In this way, the energy of the waves is converted into electrical energy through the floating board 2, which can not only generate electricity but also reduce the energy of the waves, alleviate the erosion of the waves on the bank protection dam 1, and protect the bank protection dam 1.

[0043] In the present invention, when in use, the floating board 2 floats on the water surface of the river. When the water waves brought by the ship travel reach the floating board 2, the floating board 2 rises and falls with the water waves. When the floating board 2 moves up with the water waves, the floating board 2 pulls the second connecting line 9, so that the second connecting line 9 pulls the first rotating shaft 13 on the second one-way drive connecting assembly. The rotating first rotating shaft 13 drives the second rotating shaft 16 to rotate through the one-way connecting shaft. The rotating second rotating shaft 16 drives the first gear plate 17 to rotate. The rotating first gear plate 17 drives the second gear plate 18 to rotate. The rotating second gear plate 18 drives the generator 5 to operate, so that the generator 5 generates electricity.

[0044] When the floating board 2 moves downward with the waves, the floating board 2 will pull the first connecting line 4, so that the first connecting line 4 pulls the first rotating shaft 13 on the first one-way drive connecting assembly, and the rotating first rotating shaft 13 drives the second rotating shaft 16 to rotate through the one-way connecting shaft, and the rotating second rotating shaft 16 drives the first gear plate 17 to rotate, and the rotating first gear plate 17 drives the second gear plate 18 to rotate, and the rotating second gear plate 18 drives the generator 5 to operate, so that the generator 5 generates electricity, so that the floating board 2 can generate electricity both when moving up and down, and the efficiency of power generation can be improved;

[0045] When the floating board 2 moves downward with the waves, the spring 14 on the first one-way drive connection assembly drives the first rotating shaft 13 to rotate, and the rotating first rotating shaft 13 drives the winding drum 15 on the first one-way drive connection assembly to rotate, so that the winding drum 15 reels the first connecting line 4 for use when the floating board 2 moves downward next time. In this way, the energy of the waves is converted into electrical energy through the floating board 2, which can not only generate electricity but also reduce the energy of the waves, alleviate the erosion of the waves on the bank protection dam 1, and protect the bank protection dam 1.

The rotating second rotating shaft (16) drives the first gear plate (17) to rotate. The rotating first gear plate (17) drives the second gear plate (18) to rotate. The rotating second gear plate (18) drives the generator (5) to operate, so that the generator (5) generates electricity. The electricity generated by the generator (5) can be stored in the storage battery (6) to be used by the light bar (8) at night, so as to provide lighting for the revetment dam (1) of the waterway, thereby ensuring safe travel on the waterway. b. When the floating board (2) moves downward with the waves, the floating board (2) pulls the first connecting line (4), so that the first connecting line (4) pulls the first rotating shaft (13) on the first one-way drive connecting assembly, and the rotating first rotating shaft (13) drives the second rotating shaft (16) to rotate through the one-way connecting shaft, and the rotating second rotating shaft (16) drives the first gear plate (17) to rotate, and the rotating first gear plate (17) drives the second gear plate (18) to rotate, and the rotating second gear plate (18) drives the generator (5) to operate, so that the generator (5) generates electricity. In this way, the floating board (2) can generate electricity both when moving upward and downward, and the efficiency of power generation can be improved; c. When the floating board (2) moves downward with the waves, the spring (14) on the first one-way drive connection assembly drives the first rotating shaft (13) to rotate, and the rotating first rotating shaft (13) drives the winding drum (15) on the first one-way drive connection assembly to rotate, so that the winding drum (15) reels the first connecting wire (4) for use when the floating board (2) moves downward next time. In this way, the energy of the waves is converted into electrical energy through the floating board (2), which can not only generate electricity, but also reduce the energy of the waves, reduce the erosion of the waves on the bank dam (1), and protect the bank dam (1).
