[0002] Photovoltaic power generation is a clean power generation method that directly converts solar energy into electrical energy. In the case where the available land area is very limited, the floating photovoltaic power generation system on the water surface effectively breaks through the restriction of land resources on the application of photovoltaic power generation, and the floating photovoltaic power generation device on the water surface can be combined with aquaculture to make full use of the occupied water area.

[0003] In the prior art, most of the floating photovoltaic panels on the water surface directly install floating islands on the base for floating, but the floating islands are generally fixed. In order to generate electricity better, the installation height of the photovoltaic panel is relatively fixed and higher than the height of the top of the floating island, and the distance between the photovoltaic panel and the water surface cannot be adjusted, so that when the wind force is large and the water waves are high, the photovoltaic panel is prone to capsizing.

A fixed circular plate 12 located inside the lifting buoy 7 is fixedly installed at the top of the protective cover 11. A filter pipe 15 is arranged at the bottom of the protective cover 11. A threaded rod 10 is rotatably connected to the middle of the top of the fixed circular plate 12. A piston plate 13 is hermetically slidably connected inside the lifting buoy 7.

The output end of the adjusting motor 9 is fixedly installed with the top of the threaded rod 10. The middle of the piston plate 13 is threadedly connected through the threaded rod 10. A connecting pipe 17 is fixedly installed through the main buoy 1. By setting the lifting buoy 7, when it is necessary to adjust the height of the mounting plate, the adjusting motor 9 is started to drive the threaded rod 10 to rotate, so that the piston plate 13 moves up and down along the guiding slide rod 14. When the piston plate 13 moves upward, the lake water filtered by the filter pipe 15 enters the inside of the lifting buoy 7, reducing the air above the piston plate 13 inside the lifting buoy 7, increasing the self-weight of the lifting buoy 7, and then driving the main buoy 1 and the mounting frame 4 to descend, reducing the height of the photovoltaic panel and preventing the large waves from causing inversion and capsizing.

[0023] The top of the fixed circular plate 12 is provided with guide slide rods 14 around the threaded rod 10. The guide slide rods 14 are hermetically and slidably connected to the piston plate 13. The top of the guide slide rods 14 is fixedly installed with the bottom of the main float 1. The threaded rod 10 is rotatably connected through the separation partition 8 and the bottom of the main float 1. Sealing rings are provided at the rotational connection parts of the threaded rod 10 with the separation partition 8 and the main float 1. Sealing rings are provided on the outer peripheral surface of the piston plate 13. A plurality of through grooves are formed on the outer peripheral surface of the fixed circular plate 12.

[0024] Working principle:

[0025] Through the main float 1 and the connecting float 2, the fixed plate 3 is always kept above the water surface, so that the mounting frame 4 and the photovoltaic panel are kept on the water surface. When the height of the mounting plate needs to be adjusted, the adjusting motor 9 is started to drive the threaded rod 10 to rotate, so that the piston plate 13 moves up and down along the guide slide rod 14. When the piston plate 13 moves up, the lake water filtered by the filter pipe 15 enters the inside of the lifting float 7, reducing the air inside the lifting float 7 above the piston plate 13, increasing the self-weight of the lifting float 7, and then driving the main float 1 and the mounting frame 4 to descend, reducing the height of the photovoltaic panel to prevent the photovoltaic panel from being overturned by large waves.
