The energy conversion assembly 50 is disposed on the floating body assembly 20 , and includes a transmission gear assembly 41 meshing with a synchronous gear located above, a generator 51 connected to the transmission gear assembly 41 , and an energy storage mechanism 52 connected to the generator 51 .

[0036] The water power generation device is provided with a counterweight block 11 on a counterweight base 12 so that the device is sunk into the water, and a buoyancy box 21 is connected to the counterweight base 12 by an elastic rope 60 so that the buoyancy box 21 can reciprocate up and down under the action of water waves, and a slide rail 33 and a synchronization device 31 are connected to the buoyancy box 21.

The first reinforcing beam 120 and the second reinforcing beam 121 are vertically cross-fixed and connected and arranged in a cross shape. Specifically, the counterweight block 11 is fixed at the intersection of the first reinforcing beam 120 and the second reinforcing beam 121, so that the center of gravity of the counterweight block 11 and the counterweight base 12 is on the vertical line of the center of the counterweight base 12. Specifically, the outer surface of the counterweight block 11 is coated with an anti-corrosion coating.

[0042] In this embodiment, the upper ends of the elastic rope 60 are respectively connected to the four sides of the bottom surface of the floating body support frame 22, and the lower ends are respectively connected to the two ends of the first reinforcement beam 120 and the second reinforcement beam 121. The floating body support frame 22 and the counterweight base 12 can be evenly stressed, thereby ensuring that the elastic rope 60 has a sufficiently large elastic force.

[0043] In this embodiment, the waterproof platform 53 is located at the top of the floating body support frame 22, and the four corners are fixedly connected to the tops of the four vertical rods 222 respectively; the waterproof platform 53 is raised by the four vertical rods 222, which can reduce the contact with the water surface, thereby reducing the corrosion of the water body to the waterproof platform 53. Specifically, a sealing cover 54 is provided on the waterproof platform 53, and the energy conversion assembly 50 is arranged in the sealing cover 54. Such a design can ensure the waterproof effect of the energy conversion assembly 50, and prevent the transmission gear assembly 41 and the generator 51 from being corroded and damaged due to water ingress.

Through the conversion of the reciprocating motion mechanism 30, the toothed synchronous belt 311 is driven to move, and then the first synchronous gear 312 and the second synchronous gear 313 are driven to rotate. The first synchronous gear 312 drives the one-way bearing 42 and the bevel gear and the speed-increasing gear 411 to rotate, and drives the generator 51 shaft to rotate in one direction. When rotating forward, it drives the load, and when rotating reversely, it is unloaded.
