The process of generating electricity through the floating pendulum comprises the following steps: when waves come, the floating pendulum rotates to push a piston rod of the hydraulic cylinder to extrude hydraulic oil into one of the accumulators, so that the pressure in the accumulators rises continuously, and the other accumulator is a relatively high-pressure accumulator. When the pressure in the high-pressure energy accumulator rises to a certain degree, the high-pressure energy accumulator releases hydraulic oil to push the generator to generate electricity, and the released hydraulic oil is pressed into the low-pressure energy accumulator to complete a power generation process.

Wherein the slope below is used for reducing energy loss, and if the slope is not used, a part of waves can flow under the floating pendulum, so that part of energy is lost. In order to fully utilize wave energy, the angle of the lower floating pendulum needs to be adjusted according to the frequency and the wave height of waves, and when the waves come, the waves impact a slope and excite the waves.

Therefore, the wave-resisting and water-leaking part can enable the wave-meeting plate 1 to bear and absorb the energy of the sea waves as much as possible when the wave-meeting plate hits the sea waves, and after the attack of the sea waves is completed, the sea water which originally prevents the wave-meeting plate 1 from moving flows through the plate-penetrating groove 2, so that the sea water resistance is reduced.
The posture maintaining rod used for limiting the rotation angle of the bidirectional function board 4 can be arranged between the frame plate holes 3, and the posture maintaining rod is a horizontal straight rod connected with the lower ends of the frame plate holes 3 on two sides and used for preventing the bidirectional function board 4 from being too far away from the surface of the wave-facing plate 1.
Particularly, the tail end of the bidirectional function plate 4 is also provided with a wave blocking part 5, the wave blocking part 5 is an arc-shaped panel which extends outwards from the tail end of the bidirectional function plate 4 and is gradually far away from one side of the plate penetrating groove 2, and the wave blocking part 5 can continue to be subjected to the force of seawater flowing through the surface of the bidirectional function plate 4, so that the impact energy of sea waves can be better absorbed.
