However, the offshore environment is complex, and marine environments such as waves and typhoons are extremely destructive, which poses great safety hazards to offshore photovoltaic structures, especially floating structures. Usually, the wave energy and typhoon energy are concentrated above the sea surface, and the damage to structures below the water surface is not large. Therefore, there is an urgent need for a whole-site wind-shelter device and method for floating photovoltaic panels that can realize the sinking and avoiding when the wind and waves come, and float up to generate electricity after the wind and waves stop.

It also includes a method for sheltering the entire field of floating photovoltaic panels from the wind, based on a wind sheltering device for the entire field of floating photovoltaic panels, the steps are as follows:

(1) When the wind and waves are small, the solar photovoltaic panels need to work normally. At this time, the water inside the floating cabin is discharged by adjusting the water pumps, filled with gas to increase the buoyancy, and the cables are relaxed, and the solar photovoltaic panels work normally above the water surface;

(2) When the wind and waves are strong, the solar photovoltaic panels need to avoid the sea surface wind and waves, and no longer work normally. At this time, the interior of the floating cabin is filled with water by adjusting the water pumps, increasing the weight, reducing the buoyancy, and tightening the cables. The board dives below the surface to avoid wind and waves.

Compared with the prior art, the present invention has the following beneficial effects:

The invention adopts a plurality of floating cabins to float up and sink as a whole to avoid wind and waves, and has a simple structure and low construction difficulty. The floating chamber is evenly arranged at the bottom of the steel structure grid, and the flexible adjustment of sinking and floating can be realized by adjusting the amount of gas and water in the floating chamber. Secondly, because of the uniform layout of the floating tanks, fine-tuning the water and gas of each floating tank during the process of floating and sinking can ensure the angle of the overall structure, high stability and safety. Moreover, batteries, water pumps and solar photovoltaic panels constitute a complete supply system, which ensures the reliability of equipment regulation.
