A support portion is provided at the bottom of the mounting frame 1, and a buoyancy portion is installed at the bottom of the support portion; the buoyancy portion allows the device to float on the sea surface, and the device is fixed to prevent the device from moving to other positions with the waves, so as to avoid affecting the power generation of the device by combining light energy and wave energy.

[0050] See also Figure 1 to Figure 6The support part is connected with a wave transmission part, and the wave transmission part includes an energy conversion component, which is movably mounted on the support part, and the wave energy is converted into mechanical energy through the energy conversion component, and the wave energy in the sea area where the device is located is converted into mechanical energy. The top end of the energy conversion component is connected with a rotating plate 37, and a guide ring 24 is provided on the bottom end surface of the mounting frame 1, and the guide ring 24 is slidably connected with one end of the rotating plate 37. For example, an annular groove 372 is provided on the inner wall of the guide ring 24, and a spherical sliding block 371 is slidably connected in the annular groove 372, and the spherical sliding block 371 is slidably connected in the annular groove 372.

The spherical sliding block 371 and the annular sliding groove 372 enable the rotating plate 37 to slide smoothly in the guide ring 24, thereby increasing the stability of the operation of the device and thus improving the wave energy conversion efficiency of the device. The other end of the rotating plate 37 is fixedly connected to the third transmission shaft 35, and the wave impact received is converted into the rotational power of the rotating plate 37 through the energy conversion component, so that one end of the rotating plate 37 rotates around the third transmission shaft 35, and the other end of the rotating plate 37 rotates along the inner wall of the guide ring 24. The shaft 35 is rotatably installed at the center position of the mounting frame 1. When the rotating plate 37 rotates, the third transmission shaft 35 rotates synchronously.

For example, the first generator 25 is provided with a first pulley, and the third transmission shaft 35 is provided with a second pulley. The first pulley and the second pulley are connected through the first transmission belt 36. When the third transmission shaft 35 rotates, the first generator 25 works through the cooperation of the first pulley, the second pulley and the first transmission belt 36, and then the energy conversion component is transmitted to the rotating plate 37. The rotating plate 37 rotates. The mechanical energy of the wave is transmitted to the first generator 25 through the third transmission shaft 35 and the first transmission belt 36, so that the first generator 25 works and wave energy generation is realized. The first generator 25 is installed on the bottom end surface of the mounting frame 1 and is located outside the guide ring 24. A through hole 241 is provided on the outer wall of the guide ring 24.

[0061] based on Figures 1 to 10 The present invention also proposes a method for using a power generation device combining light energy and wave energy at sea, which is used to use the above-mentioned power generation device, comprising the following steps:

[0062] The power generation device is fixed on the sea level by the buoyancy part;

[0063] Specifically, the power generation device is floated on the sea surface by the floating cone barrel 16, and then connected to the seabed foundation by the mooring cable 15. The projection of the mooring cable 15 on the horizontal plane is located outside the mounting frame 1, ensuring that the power generation device will not be strongly twisted under the action of waves, avoiding the power generation device from twisting, thereby enabling the power generation device to stably absorb wave energy and stably fix the power generation device on the sea level.

[0064] The energy conversion component is driven by the waves to move, converting wave energy into mechanical energy, pushing one end of the rotating plate 37 to rotate around the third transmission shaft 35, and the other end of the rotating plate 37 rotates along the inner wall of the guide ring 24, pushing the third transmission shaft 35 to rotate; the third transmission shaft 35 drives the first generator 25 to work through the first transmission belt 36, converting mechanical energy into electrical energy; at the same time, the photovoltaic panel 13 on the mounting frame 1 converts light energy into electrical energy.

[0065] Specifically, the photovoltaic panel 13 relies on solar energy to generate electricity, and the swing plate 2 floats on the sea surface. The waves will drive the swing plate 2 to float up and down in an irregular manner. During this process, the swing plate 2 itself will swing, so that the second connecting sleeve 40 drives the transition sleeve 39 to swing in the rotating sleeve 52, and the rotating sleeve 52 rotates in the connecting ring 22, driving the first connecting sleeve 31 to swing, and the first connecting sleeve 31 drives the first slider 41 and the second slider 43 to reciprocate in the strip slide groove 373 in the rotating plate 37, and makes the rotating plate 37 rotate, thereby driving the third transmission shaft 35 to rotate, and the third transmission shaft 35 drives the first generator 25 to work through the first transmission belt 36, thereby converting wave energy into electrical energy. At the same time, the third transmission shaft 35 will drive the first transmission shaft 11 to rotate, so that the cleaning brush 12 on the first transmission shaft 11 cleans the upper surface of the photovoltaic panel 13.

[0066] At the same time, the swing plate 2 will also float up and down on the sea surface. At this time, the swing plate 2 will drive the second connecting sleeve 40 to move back and forth in the transition sleeve 39, and cooperate with the metal rotating part 48 to rotate the first connecting sleeve 31. The first connecting sleeve 31 makes the second transmission shaft 34 rotate synchronously with the second transmission belt 46 through the constant velocity universal joint 33, so that the second generator 44 generates electricity.
