the bottom of the suspension plate 3 is connected with a fixed plate 13 through a pillar, and the bottom of the fixed plate 13 is connected with an anchoring device 14.

Specifically, the anchoring device 14 includes a weight 15 disposed on the sea bottom, the weight 15 is connected with an anchor line 16, and the anchor line 16 is connected with the fixing plate 13. The device is fixed by the anchoring device 14 and is prevented from being washed away by wind waves.

Specifically, the top of the fixing plate 13 is provided with a ballast device 17, the ballast device 17 comprises a water tank 18, the water tank 18 is arranged at the top of the fixing plate 13, the top of the fixing plate 13 is provided with a first water pump 19 and a second water pump 20, the first water pump 19 and the second water pump 20 are both communicated with the water tank 18, the first water pump 19 is used for pumping seawater into the water tank 18, the second water pump 20 is used for pumping the seawater out of the water tank 18, and the top of the water tank 18 is provided with an air pipe 21. When the stormy waves are too big, the first water pump 19 is started to pump seawater into the water tank 18, air in the water tank 18 is discharged from the air pipe 21, the load of the fixed plate 13 is further increased, the fixed plate 13 sinks, the suspension plate 3 is pulled to sink through the support, the height of the power generation device body 1 is reduced, and the problem that the device topples due to too big stormy waves is solved. After the wind wave passes, the second water pump 20 is started to discharge the water in the water tank 18, the outside air is sucked into the inner cavity of the water tank 18 through the air pipe 21, so that the fixing plate 13 floats upwards, and finally the power generation device body 1 is reset to a normal working state.

One specific application of this embodiment is:

when the power generation device body 1 encounters wind waves, the wind waves push the power generation device body 1 to move towards one side, the power generation device body 1 pushes the square sliding block 5 to slide along the sliding groove 4, the sliding rod 12 is further pushed to move, the sliding rod 12 compresses the first spring 11, meanwhile, the first spring 11 in the other buffer device 9 opposite to the compressed buffer device 9 is stretched, and the sliding rods 12 in the other two buffer devices 9 slide in the T-shaped groove 8. Through the arrangement, the impact of wind waves on the power generation device body 1 is buffered, and the problem that the power generation device body 1 is easy to damage due to the impact of the wind waves is avoided. When the wind waves impact the generating set body 1 in an inclined manner, the connecting plate 7 rotates around the inner cavity of the round hole 6 to buffer the wind waves from impacting the generating set body 1 in the inclined manner.

When the wind waves are too violent and the duration time is too long, the first water pump 19 is started to pump seawater into the inner cavity of the water tank 18, so that the load of the fixed plate 13 is increased, the fixed plate 13 sinks due to the increase of the load of the fixed plate 13, the power generation device body 1 is driven to sink, the height of the power generation device body 1 is reduced, and the scouring of the wind waves to the power generation device body 1 is reduced. The fixing plate 13 sinks to enable the second spring 24 to contract, the second spring 24 tensions the anchor cable 16 through the connecting rod 25, and the problem that the suspension plate 3 on the sea surface is pushed by wind waves to collide with each other due to the fact that the anchor cable 16 is loosened is avoided.

After the wind wave returns to the normal state, the second water pump 20 is started to pump out the water in the water tank 18, so that the fixing plate 13 floats upwards, and the power generation device body 1 returns to the normal working state. Second spring 24 is stretched when fixed plate 13 floats for the rate of tension of anchor rope 16 maintains in certain within range, avoids leading to the big problem of anchor rope 16 rate of tension change because fixed plate 13 floats and sinks through setting up telescoping device 22.
