Detailed ways

The embodiment of the present application provides an outdoor communication power supply device for supplying power to a communication device. The outdoor communication power supply device can be suspended and installed on a carrier, and there is no need to build a factory or select a site. In addition, the outdoor communication power supply device can also be self-sealed to meet the requirements of an outdoor power supply environment.

In this embodiment, the communication device is a base station. The base station is also called a public mobile communication base station, which is a form of radio station, and refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication exchange center in a certain radio coverage area. It can be understood that in other embodiments, the communication device can also be other types of communication equipment, such as wireless lightning arresters, servers, etc., which are not limited here.

In order to enable those skilled in the art to better understand the present application, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

Please refer to Figure 1, which is a schematic diagram of the use and installation of the outdoor communication power supply device in the embodiment of the present application. As shown in Figure 1, the outdoor communication power supply device 100 can be suspended and installed on a carrier 200 to power a communication device (not shown). The carrier 200 includes but is not limited to the communication device itself, walls, poles and other supporting carriers. In the embodiment of the present application, the outdoor communication power supply device 100 is suspended and installed on a communication base station and is used to power the communication base station.

Specifically, the outdoor communication power supply device 100 can be installed on the carrier 200 through a mounting structure 300. The mounting structure 300 can be integrated with the outdoor communication power supply device 100, or can be separated from the outdoor communication power supply device 100, as long as the outdoor communication power supply device 100 can be fixedly mounted on the carrier 200, which is not limited here.

As a specific implementation, the outdoor communication power supply device 100 includes a base 10 and at least one power supply module 20 detachably mounted on the base 10. The mounting structure 300 is fixed on the base 10, and the base 10 is fixedly mounted on the carrier 200.

Please refer to Figure 2 in combination. Figure 2 is a functional module diagram of the base in an embodiment of the present application. The base 10 includes an input bus, an output bus and at least one connecting portion 11. The at least one connecting portion 11 is electrically connected between the input bus and the output bus. The input bus is used to receive power from an external power source. Each connecting portion 11 is used to install a power supply module 20. The output bus is used to connect to at least one load 400 to supply power to the at least one load 400. The load 400 refers to a component in the communication device that needs to be powered.

When at least one power supply module 20 is installed on the base 10 through the at least one connection portion 11, the at least one power supply module 20 is electrically connected to the output bus, and the output bus supplies power to the at least one load 400. In addition, when the power supply module 20 is installed on the connection portion 11, the base 10 and the power supply module 20 are sealed to ensure that the outdoor communication power supply device 100 meets the requirements of the outdoor power supply environment.

It should be noted that the input bus and the output bus can also transmit signals with connected devices. For example, the input bus can transmit signals with a connected external power supply, and the output bus can transmit signals with a load.

In the embodiment of the present application, since the outdoor communication power supply device 100 can be suspended and installed on a carrier 200, there is no need to build a factory or select a site. In addition, when the at least one power supply module 20 is installed on the base 10, the at least one power supply module 20 is sealed and connected to the base 10, so that the outdoor communication power supply device 100 can also achieve self-sealing to meet the requirements of the outdoor power supply environment.

In addition, the base 10 also includes a lightning protection module 12. In this embodiment, the base 10 includes two lightning protection modules 12, and one lightning protection module 12 is arranged on the input bus, and the other lightning protection module 12 is arranged on the output bus. In this way, the outdoor communication power supply device 100 can be prevented from being affected and damaged by weather such as lightning.

In addition, in a specific implementation, the number of the at least one connection part 11 is more than two, so at least two power supply modules 20 can be connected. Since the more than two connection parts 11 are connected in parallel between the input bus and the output bus, the installation and maintenance of a single module will not affect the operation of other modules, so that the outdoor communication power supply equipment 100 will not be interrupted during maintenance.

Please refer to Figure 3, which is a functional module diagram of an outdoor communication power supply device in an embodiment of the present application. As shown in Figure 3, the at least one power supply module 20 includes at least one of a rectifier module, a high voltage direct current output module (HVDC module), a battery module, a photovoltaic module, a DC/DC module and a power distribution module.

Specifically, the rectifier module is used to convert alternating current into direct current. The HVDC module is used to output high voltage (such as 380V) direct current. The battery module is used to store energy and provide corresponding direct current power. The photovoltaic module is used to convert light energy into electrical energy. The DC/DC module is used to convert a first direct current voltage into a second direct current voltage. The second direct current voltage may be greater than the first direct current voltage or less than the first direct current voltage, depending on actual needs. The power distribution module is used to divide the existing voltage into several paths and then output them. The voltages of each path may be determined according to specific load requirements and may be the same or different.

In one embodiment, in order to simultaneously connect as many power supply modules 20 as possible to ensure power output, the number of the connecting parts 11 should be greater than or equal to the number of the power supply modules 20 .

In addition, in one embodiment, any two connecting parts 11 are electrically connected to each other. In this way, when the input bus is not connected to the power supply, one of the power supply modules 20 can also supply power to the load 400 through another power supply module 20 to meet the power supply requirements of different loads 400. For example, the battery module can supply power to one load 400 while converting the voltage through the DC/DC module to supply power to other loads 400, and the power supply modules and connecting parts can be mixed and inserted arbitrarily without restriction.

Please refer to FIG. 4 , which is a functional module diagram of an outdoor communication power supply device in another embodiment of the present application. In this embodiment, the base 10 also includes a monitoring module 13. The monitoring module 13 is electrically connected to the at least one connecting portion 11, respectively, and is used to monitor whether each connecting portion 11 is installed with a power supply module 20, that is, to monitor whether the power supply module 20 is electrically connected to the connecting portion 11. When it is detected that a certain connecting portion 11 is installed with a power supply module 20, the voltage and current of the power supply module 20 can also be detected to determine whether the power supply module 20 is faulty, thereby improving the reliability of power supply.

Specifically, a monitoring pin may be provided on each connection portion 11 for monitoring whether a power supply module 20 is installed in the connection portion 11. For example, when the connection portion 11 is installed with a power supply module 20, the monitoring pin outputs a low level, and when the power supply module 20 is inserted into the connection portion 11, the monitoring pin outputs a high level, so that whether the connection portion 11 is installed with a power supply module 20 can be monitored by the change in the level of the monitoring pin.

In addition, the monitoring module 13 can also monitor and manage the entire power supply system to obtain the voltage and current of the communication power supply system, and then obtain system status information to ensure the normal operation of the outdoor communication power supply device 100. In one embodiment, when the power supply module 20 includes a battery module, the monitoring module 13 can also be used to monitor the temperature and current of the battery to obtain battery status information. In addition, the monitoring module 13 can also be used to monitor the current of the load 400 to obtain load status information.

Please refer to Figures 5 and 6, wherein Figure 5 is a stereoscopic view of an outdoor communication power supply device in an embodiment of the present application, and Figure 6 is a front view of the base and the power supply module in Figure 5 in an embodiment. Among them, each power supply module 20 is provided with a plug-in portion 21 to realize the installation of the power supply module 20 and the connecting portion 11. In the embodiment of the present application, the connecting portion 11 and the plug-in portion 21 are both waterproof connectors, and the waterproof connector is used to realize the sealed connection between the base 10 and the power supply module 20. Specifically, if the connecting portion 11 is a male connector, the plug-in portion 21 is a female connector; if the connecting portion 11 is a female connector, the plug-in portion 21 is a male connector.

Please refer to Figures 7 and 8 again, wherein Figure 7 is a schematic diagram of the installation of the power supply module and the base in Figure 6, and Figure 8 is a cross-sectional view of the outdoor communication power supply device in Figure 5 in an embodiment. Specifically, the base 10 includes a shell, which is roughly in the shape of a rectangular parallelepiped. The shell includes a pair of main panels 101 arranged at intervals and a plurality of side panels 102 connected end to end and connected between the pair of main panels 101. The at least one connecting portion 11 is arranged at intervals on one of the main panels 101, and the other main panel 101 is suspended and installed on the carrier 200 through the mounting structure 300.

The power supply module 20 is also roughly in the shape of a flat rectangular parallelepiped, and the plug-in portion 21 is arranged on the plug-in surface 201, wherein the plug-in surface 201 refers to an end surface of the rectangular parallelepiped power supply module 20 with a smaller area. It can be understood that for the sake of aesthetics, the size of the main panel 101 along the first direction is the same as the size of the end surface of the power supply module 20 provided with the plug-in portion 21 along the first direction, so that after the power supply module 20 is installed on the base 10, the ends of the power supply module 20 and the base 10 are roughly flush (as shown in FIG. 5 ). In this embodiment, the first direction is the length direction of the end surface of the power supply module 20 provided with the plug-in portion 21.

In one embodiment, the two ends of the plug-in surface 201 along the first direction protrude in a direction away from the plug-in surface 201 to form a long flat-plate-shaped mounting portion 22, and the mounting portion 22 is provided with a mounting hole 221. Correspondingly, a pair of opposite side panels 102 of the housing of the base 10 are provided with fastening holes 14 at intervals. The number of fastening holes 14 on one side panel 102 is the same as the number of the connecting portion 11, and they correspond one to one.

The outdoor communication power supply device 100 also includes a fastener 30. When the plug-in portion 21 of the power supply module 20 is plugged into the connecting portion 11, a pair of mounting portions 22 are respectively located on both sides of the base 10, so that the mounting hole 221 corresponds to the fastening hole 14. In this way, after the fastener 30 is passed through the mounting hole 221 and the fastening hole 14 in turn, the power supply module 20 can be firmly fastened and locked on the base 10, so that the power supply module 20 can be stably installed on the base 10.

In order to make the power supply module 20 and the base 10 installed more firmly, the main panel 101 provided with the connecting portion 11 is also provided with holes 18 at intervals, and the mounting portion 22 is inserted into the corresponding hole 18, so that the mounting hole 221 and the fastening hole 14 correspond to each other.

In addition, in order to facilitate the transport, installation and removal of the power supply module 20, an operating portion 23 is provided at the end of one end surface of the power supply module 20 away from the plug-in portion 21. In this embodiment, the operating portion 23 is generally in a rectangular frame structure and is arranged at a certain angle with the main body of the power supply module 20.

In addition, a plurality of connection terminals 15 are also provided on a side plate 102 of the base 10. The connection terminals 15 include but are not limited to AC power supply terminals, DC power supply terminals, communication terminals and signal terminals. For example, when the AC power supply terminal 15 is connected to the mains, the mains can be input to the input bus. Correspondingly, a connection terminal 24 is also provided on the power supply module 20. It can be understood that the type of terminal provided on the power supply module 20 can be set according to the specific type of the power supply module, and is not limited here.

Please refer to Figures 9 to 11, wherein Figure 9 is a front view of the base and the power supply module in Figure 5 in another embodiment, Figure 10 is an installation schematic diagram of the power supply module and the base in Figure 9, and Figure 11 is a cross-sectional view of the outdoor communication power supply device in Figure 5 in another embodiment. In this embodiment, the connecting portion 11 is a connector, and the plug-in portion 21 is also a connector.

The connection part 11 is provided with a first convex wall 16 at intervals, and a sealing rubber ring 17 is also provided on the periphery of the first convex wall 16. Correspondingly, the plug-in part 21 is provided with a second convex wall 25 at intervals. The first convex wall 16 is similar in shape to the second convex wall 25, and the size of the first convex wall 16 is smaller than the size of the second convex wall 25. In one embodiment, the second convex wall 25 is formed by protruding along the edge of the plug-in surface 201 in a direction away from the plug-in surface 201. When the plug-in part 21 of the power supply module 20 is plugged into the connection part 11, the first convex wall 16 and the sealing rubber ring 17 extend into the second convex wall 25, so that the sealing rubber ring 17 is sandwiched between the first convex wall 16 and the second convex wall 25, so that although the connection part 11 and the plug-in part 21 themselves do not have a waterproof function, they can also achieve sealing and waterproofing between the power supply module 20 and the base 10.

In one embodiment, the first convex wall 16 and the second convex wall 25 are metal convex walls. Therefore, the first convex wall 16 and the second convex wall 25 can be integrally formed when manufacturing the main body of the base 10 and the main body of the power supply module 20, so that it is convenient to manufacture and is conducive to better sealing and waterproofing. In other embodiments, the first convex wall 16 and the second convex wall 25 can also be convex walls of other materials, as long as they can achieve a sealed connection between the base 10 and the power supply module 20, which is not limited here.

In the embodiment of the present application, the mounting portion 221 is formed by protruding from both ends of the second convex wall 25 in a direction away from the plug-in surface 201 , that is, the second convex wall 25 and the mounting portion 22 are integrally formed.

Please refer to Figure 12, which is a side view of an outdoor communication power supply device in another embodiment of the present application. In this embodiment, the connecting portion 11 and the plug-in portion 21 are plug-in ports, which can be circular plug-in ports, and data communication and sealed connection are achieved through a waterproof data cable 40. It should be noted that the connecting portion 11 in the embodiment of the present application is arranged on any side panel 102 of the shell of the base 10, and the plug-in portion 21 is arranged on any end face of the non-plug-in surface 201 of the power supply module 20, which is not limited here.

In addition, in this embodiment, the outdoor communication power supply device 100 further includes an adapter 50. The adapter 50 is generally "L"-shaped. One end of the adapter 50 is fixed to the plug-in surface 201 of the power supply module 20, and the other end is fixed to a side panel 102 of the base 10, thereby realizing a fixed connection between the power supply module 20 and the base 10.

The above is an implementation method of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
