Description
METHOD AND SYSTEM FOR CHARGING A LIGHT TOWER
Field of the Invention
The present invention relates to a method and system for charging a light tower.
Background
Light towers are useful for various applications, particularly outdoor illumination. For instance, portable light towers are often used in the area of mining or construction for illuminating outdoor areas when operations are conducted at night time.
Diesel-powered LED light towers are known. The cost of fuel to power such light towers is typically between AUD$8,000 - $20,000 a year for each light tower. Further, such diesel-powered LED light towers are not particularly environmentally friendly. An alternative system for powering light towers is desirable.
Summary of the Invention
According to a first aspect of the invention, there is provided a method of illuminating a mine site, the method comprising: providing a battery-powered light tower to illuminate at least a portion of the mine site; providing a charging service vehicle capable of transporting an energy storage unit between a charging station and the light tower; charging the first energy storage unit with power from a power source at the charging station; driving the charging service vehicle carrying the energy storage unit to a location where the energy storage unit can deliver power to a battery of the light tower; electrically or electromagnetically coupling the energy storage unit to the battery of the light tower; and recharging the battery of the light tower by transferring power from the energy storage unit while the energy storage unit is coupled to the battery of the light tower.
According to a second aspect of the invention, there is provided a method of illuminating a mine site, the method comprising: providing a battery-powered light tower to illuminate at least a portion of the mine site; providing a charging service vehicle capable of transporting an energy storage unit between a charging station and the light tower; charging the energy storage unit with power from a power source at the charging station; driving the charging service vehicle carrying the energy storage unit to the light tower; and exchanging a battery of the light tower with the energy storage unit carried by the charging service vehicle such that the energy storage unit is arranged to deliver power to the light source of the light tower.
The energy storage unit and the battery may be interchangeably installable in or on the light tower and each energy storage unit is capable of powering a light source of the light tower when installed, and wherein the charging station is capable of charging both the first energy storage unit and the second energy storage unit.
The charging station may receive power from a source of renewable energy, wherein the source of renewable comprises any one from the following group: a solar power system; an ocean power hydroelectric generator system; a wind power system; other source of renewable energy.
The method may further comprise driving the charging service vehicle to another battery-powered machine or tool at the mine site to recharge a battery of the another battery-powered machine or tool with the other another energy storage unit carried by the charging service vehicle.
According to a third aspect of the invention, there is provided a mine site illumination system comprising: a battery-powered light tower_to illuminate at least a portion of the mine site; a charging station for charging an energy storage unit; a charging service vehicle capable of transporting the energy storage unit between the charging station and the battery-powered light tower; wherein the energy storage unit is capable of: (a) electrically or electromagnetically coupling to a battery of the battery-operated light tower in order to recharge the battery of the light tower; or (b) being exchanged with a battery of the light tower carried by the charging service vehicle such that the battery-powered light tower is capable of being powered by the energy storage unit.
Also disclosed herein is a system for charging a light tower, the system comprising: the light tower; a first energy storage unit capable of delivering power to the light tower when connected to the light tower; a charging station for charging the first energy storage unit; a charging service vehicle capable of transporting the first energy storage unit between the charging station and the light tower; wherein the system is arranged to deliver charge from the charging station to the light tower via the first energy storage unit.
By providing a light tower that can be powered by charge delivered from a charging station, the present invention may provide the advantage of avoiding the use of diesel-powered LED light towers, and thus the costs associated therewith.
Furthermore, by delivering power to the light tower using a charging service vehicle, which may already be used to provide power to other equipment, the present invention may provide the advantage of saving on costs otherwise incurred by re-fuelling or delivering power exclusively to one or more light towers. In other words, the light towers can form part of a group of electrically-or battery-powered equipment regularly serviced by one or more charging service vehicles.
The light tower may comprise a second energy storage unit arranged to power a light source of the light tower. In this embodiment, the first energy storage unit may be associated with, or mounted to, the charging service vehicle. Further, the first energy storage unit may be capable of charging the second energy storage unit while installed in or on the charging service vehicle when electrically or electromagnetically coupled to the second energy storage unit.
Alternatively, the system may comprise a second energy storage unit capable of delivering power to the light tower, wherein the first and second energy storage units are interchangeably installable in or on the light tower and each energy storage unit capable of powering a light source of the light tower when installed. Thus, according to embodiment, instead of recharging an energy storage unit installed in the light tower, the energy storage unit can be replaced by another energy storage unit when required. The charging station may be capable of charging both the first energy storage unit and the second energy storage unit.
The system may comprise a further energy storage unit capable of being charged at the charging station and delivering power to the light tower. In this embodiment, the first (or second) and further energy storage units may be interchangeably mountable to the charging service vehicle. In other words, instead of recharging the first (or second) energy storage unit at the charging station, the first (or second) energy storage unit can be interchanged with the further energy storage unit.
Further, the charging service vehicle may be capable of transporting each energy storage unit between the charging station and the light tower. Thus, the charging service vehicle can then carry the further energy storage unit to the or another light tower, or to other equipment that needs recharging.
The charging station may comprise a source of renewable energy, wherein the source of renewable comprises any one from the following group: a solar power system; an ocean power hydroelectric generator system; a wind power system; other source of renewable energy.
By delivering power from a renewable source of energy to the charging service vehicle, and ultimately to the light tower, the present invention may provide the advantage of utilising “clean” energy and significantly reducing costs compared to diesel-powered LED light towers.
The light tower may comprise one or more of the following: at least one light emitting diode as the light source; a hollow mast supporting the light source and encapsulating at least one cable for delivering power from the energy storage unit to the light source; a 12kWh lithium ion battery as the rechargeable battery.
The charging service vehicle may be a truck. The charging service vehicle may be an electrically powered vehicle. The charging service vehicle may be used to carry one or more energy storage units to several locations to charge other electrically powered equipment.
Also disclosed herein is a method of charging a light tower using a system, the method comprising: charging a first energy storage unit with power from a power source at a charging station; driving a charging service vehicle carrying the energy storage unit to a location where the first energy storage unit can deliver power to a light tower to power a light source of the light tower; and delivering power to the light tower with power from the first energy storage unit.
The method may comprise charging the first energy storage unit with power from the power source at the charging station while the energy storage unit is carried by the charging service vehicle.
The method may comprise electrically coupling the first energy storage unit to a second energy storage unit installed in the light tower and arranged to provide power to a light source of the light tower. The first energy storage unit can then recharge the second energy storage unit.
Alternatively, the second energy storage unit may be removably installed in the light tower. The first and second energy storage units may also be substantially the same. Consequently, the first and second energy storage units can be interchangeably installed in the light tower.
The method may comprise driving the charging service vehicle carrying the first (or second) energy storage unit to the charging station. The method may then comprise interchanging the first (or second) energy storage unit with a further energy storage unit charged at the charging station. Thus, instead of recharging the first (or second) energy storage unit at the charging station, the first (or second) energy storage unit can be interchanged with the further energy storage unit.
The present invention further provides a method of illuminating a mine site, the method comprising: providing mine site illumination system comprising: a battery-powered light tower_to illuminate at least a portion of the mine site; a charging station for charging an energy storage unit; a charging service vehicle capable of transporting the energy storage unit between the charging station and the battery-powered light tower; wherein the energy storage unit is capable of: (a) electrically or electromagnetically coupling to a battery of the battery-operated light tower in order to recharge the battery of the light tower; or (b) being exchanged with a battery of the light tower carried by the charging service vehicle such that the battery-powered light tower is capable of being powered by the energy storage unit; the method further comprising the steps of charging the energy storage unit with power from a power source at the charging station; driving the charging service vehicle carrying the energy storage unit to a location where the energy storage unit can deliver power to a battery of the light tower; electrically or electromagnetically coupling the energy storage unit to the battery of the light tower; and recharging the battery of the light tower by transferring power from the energy storage unit while the energy storage unit is coupled to the battery of the light tower.

Detailed Description
Throughout this specification, the term “light tower” is used to mean a generally tall upstanding structure comprising lights at an upper end portion of the structure to illuminate a surrounding area. Light towers are typically, though not exclusively, used for outdoor illumination, and may be portable.
Figure 1 shows a system 100 for charging a light tower 102. The system 100 comprises the light tower 102, a first energy storage unit 104, a charging station 106 and a charging service vehicle 108. The first energy storage unit 104 is capable of delivering power to the light tower 104 when connected to the light tower 102, and is capable being charged at the charging station 106. The charging service vehicle 108 is capable of transporting the first energy storage unit 104 between the charging station and the light tower 102. The system 100 is arranged to deliver charge from the charging station 106 to the light tower 102 via the first energy storage unit 104.
According to a first embodiment shown in Figures 1 and 2, the first energy storage unit is in the form of a rechargeable battery 104 mounted on the charging service vehicle 108. Further, the charging service vehicle is in the form of a service truck 108 capable of supplying power from the battery 104 to other equipment, such as but not limited to high-powered mining equipment. In this embodiment, the light tower 102 comprises a second energy storage unit also in the form of a rechargeable battery 110, which is installed in the light tower 102 to power one or more light sources 112 of the light tower 102.
The charging station or dock 106 may be embodied as a fixed charging location (as shown in Figure 1) or may be transportable. The charging dock 106 comprises a connector 107 for connecting to the battery 104 carried by the truck 108 to supply charge to the battery 104. The charging dock 106 may receive power by being directly connected to an electrical power supply grid. Preferably, the charging dock 106 receives power from a renewable energy power source, such as a solar power system 113, a wave energy electrical power generation system 114 or wind power system (not shown).
Alternatively, if the charging dock 106 is transportable, the charging dock 106 may receive power from a portable power supply, such as a generator set or another energy storage unit. In that case, the charging dock 106 may comprise a hand-held device that can transfer power from a portable power supply to the battery 104 carried by the truck 108, or even directly to the battery 110 of the light tower 102. For example, in emergency situations where the light tower 102 requires immediate charging but the truck 108 is not available, a generator set or other battery can be towed to the site of the light tower 102, and a portable charger, such as an emergency “fast” charger, can be used to transfer power from the generator set or battery to the battery of the light tower 102. The fast charger may be hand-held. The generator set or battery that is towed preferably also has sufficient capacity to fully recharge the battery 110 of the light tower
In this embodiment, the battery 104 carried by the truck 108 generally remains on the truck 108. Similarly, the battery 110 of the light tower 112 generally remains on the light tower. When (or close to when) the battery 110 of the light tower requires recharging, the truck 108 can be driven to the light tower 102 to recharge the battery 110 by connecting the battery 104 of the truck to the battery 110 of the light tower. For example, as shown in Figure 2, the battery 104 can recharge the battery 110 by connecting an electrical cable 202 through power points 118 and 120 of the light tower 102 and truck 108, respectively. The battery 104 of the truck 108 in this embodiment has sufficient capacity to fully recharge the battery 110 of the light tower.
After servicing the light tower 102 and optionally other battery-powered light towers or other equipment, the truck 108 can be driven back to the charging dock 106 for its own battery 104 to be recharged. When (or close to when) the battery 104 of the truck requires recharging, the truck 108 can be driven to the charging dock 106. There, its battery 104 can be connected via an electrical cable 122 to power point 120 to a power source (not shown) at the charging dock 106 to receive charge from the power source.
With reference to Figures 2, 3A and 3B, further features of the light tower 102 according to a specific embodiment will be described. The light sources 112 of the light tower are in the form of light emitting diodes (LEDs). The light tower also 102 comprises a telescopic mast 124 supporting the LEDs 112, which can be adjusted to adjust the height of the LEDs 112 according to desired use. In this particular embodiment, when the mast 124 is lengthened to its maximum height, the LEDs 112 can be mounted over 9m above the ground. However a person skilled in the art will appreciate that the mast 124 can be configured to extend to various maximum heights. The LEDs 112 may have a total output of 2400W, which is believed to be able to illuminate an area of up to 2300 square metres of ground area when the mast 124 is fully extended.
The LEDs in this embodiment are mounted on an adjustable support head 125. As shown in Figure detail in Figure 3B, the support head 125 comprises generally horizontal arms 127 that are rotatable about a common axis A. Each arm 127 further supports at a distal end the light sources 112 such that rotation of the arms about the axis A causes the light sources 112 also to rotate about the axis A, thus changing the area of illumination. Furthermore, the support head 125 is also rotatable about a generally vertical axis B so that the light sources 112 are also rotatable about the axis B.
The mast 124 in this embodiment is hollow. The light tower 102 may thus be configured such that all cables, piping and other necessary electrical or other components for delivering power from the battery 110 to the LEDs is encapsulated within the mast 112. This reduces the risk of entanglement of the cables and may provide the advantage of a robust exterior that can withstand harsh environmental forces.
Furthermore, the mast 124 in this embodiment is collapsible, as shown particularly in Figure 2. More specifically, the mast 124 is hingedly connected to a base 126 of the light tower 102 at a hinge 128 so that the mast is pivotally movable about the hinge 128. Collapsing the mast 124 can allow for ease of manoeuvrability of the mast 124 when transported. The light tower 102 can be configured with a hydraulic system to move the mast 124 between a collapsed position (see Figure 2) and an upright position (see Figure 3A). The hydraulic system may for example include a hydraulic piston and cylinder assembly 132 connecting the base 126 and a lower portion of the mast 124. When the assembly 132 extends, the mast 124 is moved to the collapsed position; when the assembly 132 retracts, the mast 124 is moved to the upright position. Furthermore, to assist in transportability the base 126 of the light tower 102 is mounted on wheels 130.
The light tower 102 in this embodiment also has a user-interface 134 located on the base 126. The user-interface 134 provides user controls to select various operations of the light tower 102, such as telescopic extension or retraction of the mast 124 to change the height of the light tower, or moving the mast 124 between the collapsed and upright position, or changing position of the light sources 112.
An overall width of the light tower 102 may be between 2-4 metres, for example 3.2 metres. Preferably, the light tower 102 ought to be designed with a central centre of gravity to provide a stable and robust base 126.
In this embodiment, the battery 110 is enclosed in the base 126 of the light tower 102. According to an example, the battery 110 of the light tower 102 is a 120kWh battery. Preferably, the battery 110 is capable of “fast” charge, for example the battery 110 can be substantially charged in approximately 15 minutes. Further, the battery 110 may have an estimated run-time of 48 hours, which can offer approximately 4 days of 12-hour continuous operation.
According to a specific embodiment, the battery 110 is a modular battery that is removably mounted in the base 126 of the light tower 102. Thus, once removed, the battery 110 can be used in other equipment, such as dewatering pumps, generators or welders. As shown in the exploded view in Figure 3A, the base 126 of the light tower 102 can hold a plurality of removably in the base and connectable to electrical components of the light tower 102 to provide power to the LEDs 112.
With reference to Figure 4, the system 400 according to another embodiment will be described. Features in the system 400 that are the same as corresponding feature in the system 100 are given the same reference numeral.
Like the system 100, the system 400 comprises a light tower 112, a charging service vehicle in the form of a truck 108 capable of carrying an energy storage unit in the form of a battery, and a charging station (not shown). However, in the system 400, instead of the battery 104 recharging the battery 110 from the truck, the battery 104a is interchangeable with the battery 110a from the light tower 112. In other words, the system 400 is arranged to deliver charge from the charging station to the light tower 102 by the truck 108 delivering a fully charged battery 104a and swapping the battery 110a with the battery 104a. The battery 110a is thus removed from the light tower 102 once spent and replaced with another battery 104a delivered by the truck 108. It will be appreciated that in this embodiment the batteries 110a and 104a are substantially similar at least in function.
With reference to Figure 5, the system 500 according to yet another embodiment will be described. Like the systems 100 and 400, the system 500 comprises a light tower (not shown), a truck 108 capable of a battery and a charging station 106a. However, in the system 500, instead of the battery 110b remaining on the truck 108 while recharged at the charging station 106a via electrical cable 122, the battery 110b is swapped with a further battery 140 that has previously been charged. The further battery 140 is substantially the same as the battery 110b. Thus, the battery 110b is removed from the truck 108, and the further battery 140 is mounted on the truck 108. It will be appreciated that the batteries 110b and 140 in this embodiment are substantially similar at least in function. The truck 108 can then deliver the further battery 140 to a light tower or other equipment that requires power from the battery 140. A method 600 of using the system 100 according to an embodiment will now be described with reference to Figure 6. The method 600 comprises charging the first energy storage unit or battery 104 of the charging service vehicle or truck 108 with power from a power source at the charging station 106 (step 602). Then, the truck 108 carrying the battery 104 is driven to a location where the battery 104 can deliver power to the second energy storage unit or battery 110 of the light tower 102 (step 604). Specifically, the battery 104 is coupled to the battery 110 (step 606). The coupling can be done using an electrical cable 116. Then, the battery 110 is recharged by transferring power from the battery 104 to the battery 110 (step 608). While the battery 110 of the light tower 102 is being recharged, the light tower 102 can be inspected by personnel, e.g. a driver of the truck 108. Accordingly, inspection of the light tower 102 can be scheduled or occur when the battery 110 is being recharged or replaced. Optionally, the truck 108 can then be driven to another location to deliver power to other equipment or back to the charging station 106 to recharge its battery 110 (step 610). A method 700 of using the system 400 according to another embodiment will now be described. The method 700 comprises charging the first energy storage unit or battery 104 with power from a power source at the charging station 106 (step 702). Then, the charging service vehicle carrying the battery 104 is driven to the light tower 102, which has the second energy storage unit installed therein (step 704). Then, the second energy unit or battery 110 is exchanged with the battery 104 such that the battery 104 can deliver power to a light source of the light tower (step 706). Optionally, the method further involves driving the charging service vehicle 108 to another location, i.e. to deliver power to other equipment, or back to the charging station 106, e.g. to recharge its battery 110 (step 708).
It will be understood to persons skilled in the art of the invention that many modifications may be made without departing from the spirit and scope of the invention.
For example, alternative embodiments of the system may comprise a plurality of light towers to be services by the same service truck and/or a plurality of trucks and/or a plurality of charging docks.
Furthermore, the charging service vehicle may be embodied in forms other than a truck, such as a car towing a trailer or other carriage holding an energy storage unit.
As another alternative, instead of the batteries being rechargeable by delivering power from a power source via an electrical cable to the battery, the batteries may be configured to be rechargeable by wireless or inductive charging. Thus, according to a specific embodiment, the step 606 of coupling the battery 104 to the battery 110 can involve electromagnetically coupling the batteries 104 and 110 for inductive charging.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
