[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1. In this invention, seawater enters the vertical pipe through the inlet pipe, then passes through the filter plate and enters the connecting pipe and the outer casing, driving the blades to rotate. During the rotation of the blades, the connecting shaft can rotate, which in turn drives the generator to rotate and generate electricity.

[0016] 2. In this invention, the drive motor releases the rope. At this time, the restoring force of the second spring causes the movable plate to slide downward on the guide rod. During the sliding process, the movable plate can drive the insert plate to be inserted into the water inlet pipe and located in the positioning groove, thereby blocking the water inlet pipe. At the same time, the rotating shaft drives the threaded cylinder to rotate. During the rotation of the threaded cylinder, it can drive the screw to move upward. During the movement of the screw, it can drive the sealing plate and the filter plate to move upward, so that the garbage on the filter plate enters the collection hopper through the water outlet pipe, avoiding the time-consuming and laborious problem of manually cleaning this garbage, which also poses certain dangers.

[0017] 3. When the filter plate contacts the retaining ring, the sealing plate can compress the first spring and continue to move upward. At this time, the sealing plate drives the water flow in the vertical pipe to backwash the filter plate. The garbage on the filter plate enters the collection hopper through the outlet pipe with the water flow, thereby cleaning the filter plate more thoroughly, which is conducive to better power generation.

When the filter plate 703 contacts the check ring 706, the filter plate 703 stops moving, while the sealing plate 701 can compress the first spring 704 and continue to move upward. At this time, the sealing plate 701 drives the water flow in the vertical pipe 4 to reverse flush the filter plate 703. The garbage on the filter plate 703 flows with the water flow into the collecting hopper 6 through the water outlet pipe 5, and then the driving motor 1002 is reversed to reset the filter plate 703 for filtering. At the same time, the plug plate 902 moves upward to open the water inlet pipe 8 for power generation.
