A generator and a corresponding power storage device are provided inside the buoyancy assembly 2. The high-pressure hydraulic oil output by the hydraulic cylinder 103 drives the hydraulic motor to rotate, and the hydraulic motor directly drives the generator to rotate to generate electricity.

[0036] The damping suspension device 1 includes a top frame 101, a connecting seat 105, a damping buoy 106 and a damping disc body 108.

The roller A1043 contacts the central guide shaft 205, so that when the central guide shaft 205 slides, the rotation of the roller A1043 reduces friction, reduces the system operation resistance and the wear of the central guide shaft 205, and further improves the energy conversion efficiency and service life of the device.

[0040] The damping disc 108 includes a fixed block 1081, a connecting column 1082, and a baffle A 1083.

[0042] The roller guide support B203 includes a fixed ring B2031, a support rod B2032 and a roller B2033. The fixed ring B2031 is connected to the float 202.

[0043] The float 202 is shaped like a truncated cone. A rubber buffer 204 is mounted on the outer wall of the retaining ring B2031 on the support rod B2032, away from the float 202.

Buoy A301 is mounted on a connecting chain 303 connected to the damping suspension device 1, and buoy B302 is connected to the ground anchor 304 via the chain 303. By adjusting the length of the anchor chain 303, the anchoring device 3 can be installed in any sea area. The buoyancy generated by buoy A301 balances the weight of the chain 303 from buoy B302 to the damping suspension device 1, while the buoyancy generated by buoy B302 balances the weight of the chain 303 from buoy B302 to the ground anchor 304, preventing the weight of the chain 303 from affecting the operation of the device.

[0048] S2: Use a towing vessel to adjust the position of the anchoring device 3. After the adjustment is completed, observe the draft depth scale of the floating body 202 and adjust the number of balancing weights 107 to make the device reach the expected design center position. After the adjustment is completed, open the working valve of the hydraulic cylinder 103 to start the generator.
