Use of tidal waves and the kinetic energy stored in the waves are very important source for harnessing energy, in particular electricity. Though numerous researches are being conducted world wide, by several research authorities and at the same times several patents have been granted to certain technologies related to application of tidal waves towards harnessing electricity, any economical commercially successful such technology for industrial application is hardly known.

[0003] Therefore further research in this field is required for developing certain new technology, which can be commercially used for mass electricity generation from tidal waves. In Indian context, tidal wave based technologies for generating electricity, is very important, as India has vast costal line and any such development may supply enough electricity economically.

[0005] Another object of the present invention is to prepare an artificial inclined platform with certain uniform/non-uniform slope(s) to accumulate the force of the incoming tidal waves on the proposed platform and strike on the plate/steel wall suspended on Boat shaped swing and then terminate, so that without allowing the trapped tidal waves to reach its natural tip (end point) on the sea shore, its maximum energy can be utilized/transformed in creating to and fro oscillations in the said suspended obstacle, i.e. the boat shaped swing, enabling to rotate the shaft of the electricity generator means. [0006] Another important object of the present invention is to propose a novel gear assembly, which is connected to the upper end of the suspended obstacle (i.e. at the 1^st=first shaft) and the main shaft of the electricity generator means (i.e. mainly the alternator), wherein the said gear assembly is designed in such a manner that it is capable of rotating the final shaft continuously in single direction, irrespective of clockwise or anticlockwise, movement of the main shaft without getting affected by the to and fro oscillation of the said suspended boat shaped swing.

[0007] Further object of the present invention is to propose a novel method to generate electricity by installing the proposed system herein on the proposed artificial platform herein at the sea shore, followed by operating various components/devices of the said system with the help of tidal waves, in an optimized manner so that the electricity generator can generate electricity, Continuously.

Description of the Present Invention:

[0009] The present invention proposes a unique system in the form of a machine assembly installed at a sea shore at low tide level, wherein this proposed system involves a novel method towards its operation/functioning using the energy of tidal waves, and wherein the proposed system is capable of generating electricity. The structural features of the proposed system and the method of its operation towards electricity generation are substantially described herein. [0010] The proposed system as a machine assembly mainly comprises of: i. A inclined platform or a channel and sea bed; ii. A rigid structural framework; iii. A suspended and oscillating obstacle to the tidal waves, preferably in the form of a boat shaped swing; iv. A gear assembly, and a Gear-box; v. Electricity generation means.

[0011] The inclined platform or a channel and sea bed: The inclined platform or a channel and sea bed is constructed in such a manner that it (a) allows more water to flow into the channel; (b) creates more forceful tidal waves; (c) maintain uniformity in the direction of waves and supports the upward motion of the ebb tides on the inclined platform till they reach maximum height, that is they reach their tipping point; (d) transforming maximum tidal wave force on the boat shaped swing thereby allowing it to travel the optimized oscillation path.

[0012] The inclined platform is basically designed in such a manner that it has a wide mouth/opening at the sea side approximate 10 mtrs wide, allowing more water to enter into the channel / platform and gradually its sides get narrowed towards the sea-shore side upto 2.5mtr wide at point 'B' and remains constant (i.e. 2.5mtrs.) for Rest of the length of the platform/channel. At the same time, the bed of the said platform or channel is preferably elevated at certain angles from point 'A' to 'D' so that the incoming tidal waves or the incoming water rises more than the surrounding sea and can hit the suspended obstacle of the proposed system with certain effective force. [0013] The rigid structural framework: Towards the narrow end of the said inclined platform or the channel a rigid structural framework is constructed, wherein the said rigid structural framework is preferably a steel/RCC structure having pillars firmly fixed and concreted below the ground/sea bed, and beams supported on the pillars. The boat shaped swing as a suspended and oscillating obstacle to the tidal waves is suspended from the said beams herein. This rigid structural framework is so constructed that it can firmly stand on the sea shore, without being practically damaged due to the tidal force continuously. Further this framework is responsible for suitable and stable installation of the Gear assembly well connected to the alternator above the beams and at the same time for firmly holding the suspended boat shaped swing and oscillating obstacle below the beam.

[0014] The suspended and oscillating obstacle to the tidal waves, preferably in the form of a boat shaped swing: This suspended and oscillating obstacle to the tidal waves is actually hanging below the beam/roof of the said rigid structural framework of the proposed system at point 'c' (i.e. middle of B and D) with the help of a long and suitable arm. This suspended and oscillating obstacle is preferably a boat shaped swing which is suitably connected to a long and strong arm, and this long arm at its upper end is associated to the Gear assembly, mounted above the beam. On the boat shaped swing there is a vertical plate/wall mounted in such a way that it can create an effective resistance to the motion of the incoming tides/water in its path. The swing reaches its optimum upward position, along with the incoming tidal waves/water, and then due to gravitational pull it returns back and during this returning motion, it goes beyond its vertical mean position to travel on the other side towards the direction of sea. Therefore the suspended boat shaped swing, due to tidal waves continuously perform to and fro oscillations, which is the key process for operating the electricity generation means through the gear assembly, directly associated to the shaft of the said oscillating swing.

[0015] The gear assembly: Above the beam/roof of the said rigid structural framework of the proposed system, at least one gear assembly is suitably placed/mounted, on the shaft (first) which is associated to the long arm of the suspended and oscillating obstacle or the boat shaped swing at one side and at least one electricity generation means or alternator attached to the final shaft of the gear system at other end, wherein the said suspended and oscillating obstacle or the boat shaped swing is positioned below the said beam/roof of the said rigid framework.

[0016] During the to and fro oscillations of the suspended and oscillating obstacle, preferably the boat shaped swing, the said gear assembly receives the input force towards rotating its final shaft at certain predetermined RPM, wherein the said final shaft of the gear assembly is suitable associated to the alternator. This gear-box, due to its unique assembly of gears, is capable of converting the to & fro movement of the first shaft and first Gear derived from the to & fro oscillation of the suspended boat shaped swing into the single direction thereby rotating the final shaft of the gear assembly attached to the alternator, in one direction and therefore this Gear assembly is the key device of the proposed system herein for utilizing the both way movement (to and fro) of the said swing. [0017] Electricity generation means: The Gear assembly or the Gear box is suitably mounted with the electricity generation means, which is preferably at least one alternator. The said alternator is connected to the final shaft of the said gear assembly with the V-BeIt After receiving the input force due to oscillation of the boat shaped swing, through its customized multiple gear assembly, it rotates the alternator at a predetermined RPM so that electricity generation becomes practically feasible.

[0018] For converting Tidal Wave force into energy, the present invention proposes followings:

[0019] 1] a) Collection of more water (wider mouth) b) An inclined platform or channel

[0020] 2] Modification in the sea bed

[0021] 3] Creation of a mechanism/obstacle capable of obstructing and absorbing maximum force from tidal wave thereby oscillating the obstacle along with tidal wave towards rotating the shaft of the electricity generation means or the alternator through a customized Gear box assembly, which is capable of utilizing both way oscillations (i.e. to and fro) of the said obstacle for rotating the said shaft of the said electricity generation means or the alternator continuously in single direction.

[0022] 4] Utilization of at least one Alternator & generator assembly for generating electricity.

[0023] The mechanism capable of absorbing maximum force from tidal wave: The proposed mechanism comprises a set of equipments/tools and a method to integrate^' and operate these equipments/tools. The set of equipments/tools consists of:

[0024] (a) SWING (Referring to the suspended and oscillating obstacle or preferably the Boat shaped swing herein): It is a component of the proposed system in the form of a Boat shaped swing, preferably of Steel/RCC structure and with structural property; wherein the swing is suspended from the solid steel shaft (main shaft) of the gear box & alternator assembly, kept at the beam/roof of the rigid structural framework through a suitable steel rod/shaft integrated with it, which is termed as the arm of the swing. The said arm of the swing, through its end away from the suspended embodiment, passes through two bearings, each fixed on the beams placed on either side of the rigid structural framework. Through said arm of the said swing the said shaft of the gear box & alternator assembly moves (rotates) along with the movement of the swing and the bearings ensure easy rotation of the shaft. During High tide, the tidal wave strikes with force on the vertical plate/wall of the said swing and the swing moves along with the wave from A (mean vertical lowest position) to B (optimum up position towards sea shore side) thereby rotating the said arm of the swing at least upto 45° or more. As soon as tidal wave passes away, the level of sea water falls down abruptly allowing the said swing to travel back from B to A and further travel upto C (optimum up position towards sea side) under gravitational force, The swing travels in the opposite direction (B to C) almost equal to the distance it had traveled with the strike of the tidal wave, as such the arm/steel rod rotates in the opposite direction. During such movement of the swing from (B to C) the rotation of the arm/steel rod is more than 90° The swing again returns back to the position 'A', that is the mean vertical lowest position under gravitational force, thereby rotating the said arm/steel rod again to another 45° as such one cycle is completed, i.e. the swing travels to and fro from A to B, then from B to A, then A to C and then C to A to complete one cycle. During such movement, the shaft rotates by (45° + 45° + 45° + 45°), which is a sum total of 180° for completion of one cycle of movement of the swing. In a practical exemplary illustration, it may be noted that when a swing with a arm of 10 ft is suspended from its axis at Gear box & alternator assembly then the time taken by the swing in completing one cycle of its to and fro oscillation is approximately 9 seconds. Since there are 6 to 7 tides in one minute, that is one tide in every 9¹/₂ seconds, the swing is perfectly optimized and ready to take the strike of the next wave immediately and continue to rotate the shaft of the Gear box with the next strike of the tidal wave, continuously one after another during high tide.

[0025] (b) Two bearings are firmly fixed on the beams of the steel/RCC structure and these two bearings hold the solid steel rod/shaft or the said arm of the suspended obstacle, i.e. the boat shaped swing herein.

[0026] (c) The boat shaped swing is suspended from the solid steel shaft and the first Gear is also mounted on the same shaft, which in turn rotates other gears of the gear box & alternator assembly with the help of steel rod/shaft (the said arm of the swing), which are capable of holding the heavy swing and absorb the jerks during the 'to & fro' movements of the swing.

[0027] (d) A thick plate/sheet or wall, preferably of steel & of suitable dimension, fabricated on a strong frame, preferably of steel, to tame/obstruct the tidal wave force, where this thick plate/sheet/wall is to be mounted vertically on the Boat shaped swing.

[0028] (e) Gears and Gear Box (Gear assembly) is placed above the beam/roof of the rigid structural framework and connected to the said swing, below the said beam/roof of the said rigid structural framework so that the movement of the swing is easily passed on to the "Gear assembly". There are preferably three Gears mounted on three shafts plus a Gear box for multiplying the rotation of the final shaft upto 1500 to 1600 rotation per minutes (RPM). All the three shafts and the shafts in the Gear Box are supported on Bearings for easy movement.

[0029] (f) GEAR BOX: In the Gear Box, there are two gears on one shaft then there are two Rachet gears and a Middle gear on the second shaft and again a gear on the third shaft (final shaft). Since the swing moves To and FRO' and the main shaft also rotates accordingly i.e. 45° clockwise then 90° anticlockwise and again 45° clockwise. It is necessary that the final shaft attached to the alternator should move in one direction only and this is achieved by using "Rachet Gears" system in the Gear Box. There are two Rachet Gears in the Gear box and one Rachet Gear operates when the main shaft moves clockwise and the other Rachet Gear becomes non-functional, similarly when the main shaft moves in the Anti-clockwise direction the other Rachet Gear starts functioning and the first Rachet Gear becomes non functional. The Rachet Gear system is designed in such a way that the final shaft attached to the alternator rotates in one direction only in the magnetic field, irrespective of the "to and fro" movement of the arm of the swing and the total suspended embodiment. The third shaft in the gear box is connected to the Pulley of the Alternator for generation of electricity through V-BeIt. However the placement of Gear and Gear Box can be interchanged as per requirement as the main criteria is to achieve rotation of the final shaft up to 1500 to 1600 RPM.

[0030] (g) FLYWHEELS: There are two flywheels placed on either side of the third shaft (Final shaft) and the movement (Rotation) of the flywheel ensures the continuous movement of the final shaft there by maintaining the uninterrupted and continuous movement / Rotation of the rotor of the alternator.

[0031] (h) ALTERNATOR: Alternator is connected to the final shaft through pulley & V-BeIt and since the gear assembly is capable of rotating at the rate of 1500 to 1600 RPM and also a lot of torque is available from each strike of Tidal wave on the thick plate/sheet or wall of the suspended and oscillating obstacle, i.e. the boat shaped swing herein, then the shaft, gears & Gear Box transfer enough force on the alternator to generates electricity continuously.

[0032] When above mentioned proposed system is installed properly on the ^* Sea bed between low tide and high tide; preferably closer to low tide area the proposed swing is allowed to oscillate forward/upward and backward along with the tidal waves, and the gravitational force involved therein to maintain the momentum of the suspended obstacle/swing, and consequently the proposed system rotates/operates the electricity generator means, i.e. preferably at least one alternator herein effectively, leading to electricity generation. Therefore it is a totally new and innovative method for utilizing the tidal wave energy. Description of the invention with the help of drawings:

[0041] Figure 1: is simply a comparative analysis of the movement of tidal waves and the figures also show the tipping points of the waves.

[0042] In case (a) the tidal waves, mainly start rising at natural elevation of the sea-bed and finally touch the sea-shore naturally, no matter in high tide or in low tide. When a platform of suitable dimension, depending on several local factors, is constructed on the sea shore, two situations are very much likely:

[0043] Case (b): Here the tidal waves, start rising at the starting point 'A' of the proposed platform/channel herein and travel lesser distance than the normal (than naturally terminating waves) distance on the elevated platform and terminate early than normal, at certain height.

[0044] Case (c) not depicted in the drawing: Here the tidal waves, start rising at the starting point 'A' of the proposed platform and travel more distance than the normal (than naturally terminating waves) distance on the elevated platform and terminate late than normal, at certain height.

[0045] Figure 2: shows that a large volume of incoming water 11 with tidal waves is trapped on the segment 'AB' of the proposed platform. This segment 'AB' is very much inside the normal water level at the sea shore 10, preferably starts at that point where low tide begins rising. Water trapped, with tidal waves moves forward/upward on the platform and travels on the segments 'BC and 'CD'. Segments 'AB' and 'CD' are comparatively more inclined than the middle segment 'BC, which is very much horizontal. The segment 'CD' has certain openings/windows in the side walls for easy and quick disbursement of incoming water. Thus on the proposed platform, the direction of movement of tidal waves is tried to make uniform and unidirectional.

This Framework 1 , mainly mounts the Gear-Box assembly and the electricity generation means above its beams 2, or on the roof above the beams 2. Further this Framework 1 uniquely integrates the Boat shaped suspended obstacle (the Swing herein) 4, via the arm 5 of the said Swing 4 with the suitable shaft of the Gear-Box, and therefore the said Boat shaped suspended obstacle 4 remains suspended below the beams 2 and makes its provisioned to and fro oscillations freely. The Boat Shaped Obstacle 4, mounts a vertical plate or wall 6 on it.
