The buoy 14 can move relative to the rotating ring 20, and the combined generator is always in the flow direction of the ocean current under the action of the ocean current, so under the action of the ocean current, the combined generator exerts a pulling force on the rotating ring 20 through the rope 8 , the rotating ring 20 can rotate around the buoy 14 under the drive of the rope 8 .

During the rotation of the buoy 14, the generator coil 13 in the column 12 cuts the magnetic induction line to generate electric energy, because the rotating ring 20 is rotated and arranged on the buoy 14. Therefore, the rotating ring 20 and the buoy 14 can move relative to each other. During the rotation of the floating body 14, the rotating ring 20 does not move under the action of the combined generator, so the rotation of the buoy 14 will not affect the rotation. The rotation of the ring 20, that is, the buoy 14 will not cause the rope 8 to be wound on the cylinder 14 or the column 12 and affect the operation of the combined generator.

Specifically, the surface of the steel ball 22 is provided with a rubber layer 22a. The rubber layer 22 a acts as a buffer to prevent the steel ball 22 from directly colliding with the piezoelectric material layer 23 and destroying the piezoelectric material layer 23 .

The moving plate 7 can slide on the guide rail 1a. Under the pulling force of the rope 8, the two moving plates 7 enable the two triangular tubes 5 to move towards each other at the same time to complete the insertion, and the stability is good.

When the ocean current at sea is large, the buoyant body 2 drifts far away driven by the ocean current, and the pulling force of the rope 8 is greater than the elastic force of the return spring 6, so that the rope 8 is tightened and pulls the moving plate 7 to slide on the guide rail 1a, moving The plate 7 abuts against the triangular cylinder 5 and drives the triangular cylinder 5 to overcome the elastic force of the return spring 6 to move, so that the two triangular cylinders 5 are inserted into each other through the elongated gap 5a on the upper surface to form a cylinder with six edges , the cylinder with six edges rotates under the push of the ocean current, thereby driving the generator 4 to generate electricity, and at the same time, the thin-film solar cell-5c simultaneously generates electricity under the irradiation of sunlight, and the electricity generation efficiency is high.

When the ocean current is small, the pulling force of the rope 8 is less than the elastic force of the return spring 6, and the two triangular tubes 5 are separated from each other, so that the thin film solar cell-5c on the surface of the triangular tube 5 can receive sunlight with the largest area to realize solar power generation.

The fixed pulley 10 can play a guiding role, that is, change the direction of the rope 8, and also enable the two moving plates 7 to keep moving synchronously and more smoothly.
