Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to an autonomous protective photovoltaic power generation device. Background Art
[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electricity. It primarily consists of three main components: solar panels (modules), a controller, and an inverter, with the majority of these components made of electronic components. Solar cells are connected in series and then encapsulated and protected to form large-scale solar modules. Existing photovoltaic power generation systems operate solely by absorbing and converting sunlight to generate electricity. However, high wind speeds often carry dust particles that can strike the solar panels, causing cracks on the panels' exterior and affecting their subsequent efficiency. Utility Model Content

At this time, the pneumatic cylinder begins to extend, thereby driving the main box and the guide frame, the rotating frame, and the solar panel to start moving upward, further preventing the surrounding from blocking the photovoltaic power generation device and further ensuring that the photovoltaic power generation device can work stably.
[0011] 2. The utility model starts by two sets of symmetrical rotating motors, which drive the rotating shaft, rotating frame and solar panels to rotate forward forty-five degrees, thereby ensuring sufficient light absorption in the morning.

[0027] Specific workflow:
[0028] During installation, the chassis 24 is placed on a flat ground with the front end of the main box 11 facing east. Screws are then driven into the four evenly distributed positioning holes 25 to further ensure the rapid installation and fixation of the photovoltaic power generation device, thereby ensuring subsequent stability. The pneumatic cylinder 23 then begins to extend, thereby driving the main box 11, the guide frame 17, the rotating frame 20, and the solar panel 22 to move upward.
