CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] This patent application is a patent of addition and is an improvement over a patent application titled “WAVE ENERGY CONVERTER - POINT ABSORBER” having application number “201821043737” and filed on November 20th, 2018.
TECHNICAL FIELD
[002] The present disclosure, in general, relates to the field of power generation. More particularly, the present subject matter relates to a wave energy converter.
BACKGROUND
[003] Generally, with increase in manufacturing and consumer sector, there is a greater need for development of green energy resources to fulfil the energy demand. The ocean waves contain tremendous energy and are considered as major source of renewable energy. The ocean waves possess a high and continuous kinetic energy. The captured energy can then be used for electricity generation and for powering various plants. The energy produced by the ocean waves are continuous as the waves occur all though the day however, the pattern of the waves is unpredictable and inconsistent.
[004] Different method and techniques are developed to utilize the energy generated by the moving oceanic wave. The existing techniques include an acceleration tube attached to a buoyant body. An intermediate section of the acceleration tube defines a working cylinder, with openings in the acceleration tube above and below the working cylinder allowing unobstructed flow of water between the working cylinder and the body of water in which the acceleration tube is immersed. A working piston reciprocates in the working cylinder. A relief passage at each end of the working cylinder is controlled by the working piston to allow unrestricted flow past the working piston when the piston moves past a predetermined position at the end of the working cylinder. An energy absorbing device is connected to the working piston. A restoring device is provided to apply a return force to the working piston towards the working cylinder, if the working piston moves past the predetermined position. Typically, the efficiency of a blade, as disclosed, cannot be maintained same in both directions of the water flow. This leads to uneven blade deformations, reduction in the efficiency due to vortices generated at the rotating blades. Therefore, a wave energy converter with increase efficiency of the overall wave converter is of utmost importance.
[005] Another technique may include a wave energy converter (WEC) that contains a shell suitable for being placed within a body of water. The shell contains an internal oscillator comprising a "reaction mass and a spring mechanism coupled between the reaction mass and the shell. The shell and internal oscillator are constructed such that, when placed in the body of water and in response to waves in the body of water, there is relative motion between the shell and the internal oscillator's mass. A power take-off (PTO) device is coupled between the internal oscillator and the shell to convert their relative motion into electric energy. Typically, utilization of such spring systems as disclosed, leads to fatigue and the efficiency of the spring deteriorates with time.
[006] The present disclosure is directed to overcome one or more limitations stated above or any other limitation associated with the conventional arts and to disclose a system to utilize the inconsistency of the waves in an optimized manner to enhance the efficiency of the energy production.

[0027] The present subject matter discloses a wave energy converter 100. The wave energy converter 100 comprises at least one oscillating body 102, a stationary body 104, a piston 106, a connecting arm 108 for each of the oscillating body 102, a power take off system 110 and a control mechanism 120. The oscillating bodies 102 are configured to be exposed to a surface of a water body. The stationary body 104 is configured in accordance to number of oscillating bodies and provided with a mooring arrangement to restrict the motion of the stationary body 104. The piston 106 is configured to move to and fro inside the stationary body 104 to oscillate a liquid 105 across the power take off system 110. The connecting arm 108 is configured to be mounted on the stationary body 104 and configured to convert movement of the oscillating body 102 into reciprocating motion of the piston 106. Further, the connecting arm 108 is configured to be selectively connected with the piston 106 based on the controls provided by the control mechanism 120.
[0028] In an exemplary embodiment of the present subject matter, as illustrated in figure 1 and 2, the wave energy converter 100 is configured with three oscillating bodies (102a, 102b, 102c) distributed at an angle of 120° around the stationary body 104. However the same configuration/ setup is not limited to three oscillating bodies and can be configured with multiple oscillating bodies 102. The oscillating bodies (102a, 102b, 102c) are rigidly connected with respective connecting arms (108a, 108b, 108c) to transfer the wave motion to the piston 106 for reciprocating into the stationary body 104. The number of oscillating bodies 102 are selected to balance the wave energy converter 100 always in an upright stable position.
[0029] Referring to figure 3, the wave energy converter 100 with one exemplary oscillating body 102a and connecting arm 108a is described. The wave energy converter 100 further comprises the power take off system 110 configured to convert reciprocating motion of the piston 106 into rotary motion of a fixed turbine 115 for energy production. Further the power take off system 110 is having a pair of solid structures (111, 112) positioned on the opposite walls of the stationary body 104. The fixed turbine 115 is placed between the solid structures 111 and 112. The power take of system 110 utilizes the energy generated by the motion of ocean waves to rotate the fixed turbine 115. The piston 106 reciprocates in the stationary body to pull and push the liquid 105 through the power take of system to rotate the fixed turbine 115. The fixed turbine 115 is further connected to the energy generator 118 to convert the rotational energy produced by the fixed turbine 115 into electrical energy. Since the cross-section of the solid structures 111 and 112 is reduced at View AA’ and View BB’ respectively, the velocity of the liquid 105 gets increased which results in a higher Rotation per Minute (RPM) of the fixed turbine 115. Thus the structure of the power take off system 110 also increases the torque generated on the fixed turbine 115 because of the solid structures 111 and 112. The crest and trough created by the waves and the self-weight of the oscillating bodies 102 act as active and restoring forces which provide consistent energy. The type of liquid 105 is selected based on its density, viscosity, flash point in order to configure working of the wave energy converter in accordance to the present subject matter.
[0030] Now Referring to Figure 4a, the control mechanism 120 for an exemplary oscillating body 102a and connecting arm 108a of the wave energy converter 100 is illustrated. The control mechanism 120 comprises a sensor 122 for each of the connecting arms 108, a powering actuator 124 for each of the connecting arms 108, a stopping actuator 126 for each of the connecting arms 108 and a control unit 128. The sensor 122 is configured to sense speed and direction of movement of the respective connecting arm 108. The powering actuator 124 is mounted on the piston 106 and is configured for locking the connecting arm 108 with the piston 106. The stopping actuator 126 is mounted on an inner surface of the stationary body 104 and is configured for locking the connecting arm 108 with the stationary body 104. The control unit 128 is configured to receive data from each of the sensors 122 and to actuate either the powering actuator 124 or the stopping actuator 126 of a particular connecting arm 108 according to a predefined condition. Further the control unit 128 is configured to control the movement of the connecting arms 108 to provide continuous motion to the piston 106. In an exemplary embodiment, the number of oscillating bodies 102 is selected to be three (102a, 102b, 102c). Therefore the corresponding elements such as the connecting arms (108a, 108b, 108c), the sensors (122a, 122b, 122c), the powering actuators (124a, 124b, 124c) and the stopping actuators (126a, 126b, 126c) are also three one for each of the oscillating body (102a, 102b, 102c). The figure 4b illustrates a top view of the control mechanism 120 comprising stopping actuators (126a, 126b, 126c) engaged with the connecting arms (108a, 108b, 108c).
[0031] In an embodiment, the control unit 128 is configured to actuate the stopping actuator 126 for locking the movement of the connecting arm 108 when the connecting arm 108 is configured to move the piston 106 further to an extreme position such as a top position or a bottom position. In another embodiment, the control unit 128 is configured to actuate the stopping actuator 126 for locking the connecting arm 108 configured to move the piston 106 in opposite direction to the movement of other connecting arms. In another embodiment, the control unit 128 is configured to actuate the stopping actuator 126 for locking the connecting arm 108 moving in opposite direction to the movement of the piston 106. In another embodiment, the control unit 128 is configured to actuate the powering actuators 124 for connecting the connecting arms 108 having higher speeds in same direction.
[0032] As per the wave spectra of the region in which the wave energy converter 100 is to be placed, the lengths of the connecting arms 108 are configured. The wave energy converter 100 will encounter the waves such that either one oscillating body 102 is set to motion due to crest wave and the other two oscillating bodies 102 are set to motion due to trough wave or vice-versa. In order to harness most optimum energy from the wave spectra, the motion of the oscillating bodies 102 are to be regulated which in-turn regulates the motion of the piston 106. Further an exemplary control mechanism for a wave energy converter 100 comprising three oscillating bodies (102a, 102b, 102c) is explained with the help of below table considering various possible positions of the piston 106 inside the stationary body 104.

[0033] Referring to the table A, in condition 1(a), 1(b) and 1(c) the piston has reached the top most position inside the stationary body. Further upwards movement of the piston will damage the wave energy converter. Therefore, the control unit receives this data from the sensors and actuates the stopping actuator for locking the movement of the connecting arms moving in upwards direction.
(i) Hence in condition 1(a) the connecting arms 108a and 108b are held by the stopping actuator and the connecting arm 108c is connected to the piston by the powering actuator to provide the piston a downward motion i.e. the oscillating body 102c is allowed to heave upwards.
(ii) In condition 1(b) the connecting arms 108a and 108c are held by the stopping actuator and the connecting arm 108b is connected to the piston by the powering actuator to provide the piston a downward motion i.e. the oscillating body 102b is allowed to heave upwards.
(iii) Similarly in condition 1(c), the connecting arms 108b and 108c are held by the stopping actuator and the connecting arm 108a is connected to the piston by the powering actuator to provide the piston a downward motion i.e. the oscillating body 102a is allowed to heave upwards.
[0034] Further in condition 2(a), 2(b) and 2(c) the piston has reached the mid position inside the stationary body. In this position, the piston 106 is free to move upwards or downwards. Therefore, the control unit receives this data from the sensors and actuates the stopping actuator for locking the movement of any two slow moving connecting arms (108a, 108b, 108c).
[0035] In Referring to the table A, in condition 3(a), 3(b) and 3(c) the piston has reached the bottom most position inside the stationary body. Further downwards movement of the piston will damage the wave energy converter. Therefore, the control unit receives this data from the sensors and actuates the stopping actuator for locking the movement of the connecting arms moving in downwards direction.
(i) Hence in condition 3(a) the connecting arms 108a and 108b are held by the stopping actuator and the connecting arm 108c is connected to the piston by the powering actuator to provide the piston a upward motion i.e. the oscillating body 102c is allowed to heave downwards.
(ii) In condition 3(b) the connecting arms 108a & 108c are held by the stopping actuator and the connecting arm 108b is connected to the piston by the powering actuator to provide the piston a upward motion i.e. the oscillating body 102b is allowed to heave downwards.
(iii) Similarly in condition 3(c), the connecting arms 108b and 108c are held by the stopping actuator and the connecting arm 108a is connected to the piston by the powering actuator to provide the piston a upward motion i.e. the oscillating body 102a is allowed to heave downwards.
[0036] Figure 5 illustrates the design and shape of the oscillating body 102. The Oscillating body 102 is configured to be made from low density buoyant material which helps it to float on the water body. Further the oscillating body 102 is designed to have maximum heave motion. The shape of the oscillating body 102 is configured to be an aerodynamic design to obtain lift motion due to the wind.
