Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, in particular to a high-efficiency cleaning component and a photovoltaic panel. Background Art

[0002] Photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). The direct photoelectric conversion method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for photoelectric conversion is the solar cell; a solar cell is a device that directly converts solar energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When sunlight shines on the photodiode, the photodiode will convert the solar energy into electrical energy and generate current. Photovoltaic panels are often installed in rows outdoors. They are exposed to wind and rain, and dirt is inevitable on their surface, which will directly affect their power generation efficiency. Therefore, cleaning of photovoltaic panels is particularly important.

[0004] Regarding the above-mentioned related schemes, the photovoltaic panel is cleaned by the cooperation of the roller and the cleaning brush. During actual operation, the roller rolls downward along the inclined photovoltaic panel under the action of gravity, and drives the cleaning brush to roll at the same time to clean the photovoltaic panel. However, in this process, since the cleaning brush rolls in the same direction as the downward movement, the friction between the cleaning brush and the photovoltaic panel is small, which makes it difficult for the cleaning brush to achieve comprehensive and deep cleaning of the photovoltaic panel, and the cleaning effect is poor. Summary of the invention

[0017] 1. The present invention is provided with a cleaning mechanism and a flushing mechanism. When the driving motor is working, the output end of the driving motor drives the rotating shaft and the gear to rotate. Since the gear is meshed and connected with the tooth plate, the gear and the outer frame move along the tooth plate, so that the surface of the photovoltaic panel can be cleaned by a cleaning plate that is tightly fitted with the surface of the photovoltaic panel, and the dirt on the surface of the photovoltaic panel is flushed by the electric-controlled nozzle on the left side to loosen the dirt, thereby providing convenience for cleaning the dirt by the cleaning plate.
