Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, in particular to a cleaning robot used for photovoltaic panels. Background Art

[0002] Photovoltaic panels use the principle of solar energy's photoelectric effect to convert solar radiation energy into direct current. They have the characteristics of high photoelectric conversion efficiency, good stability, environmental protection and no noise. Photovoltaic panels are usually installed in open areas or on top of buildings. Dust and impurities in the air will accumulate on the surface of the photovoltaic panels, affecting the sunlight and reducing the power generation efficiency. Generally, a cleaning device is used to clean the dirt on the photovoltaic panels, and a cleaning robot generally uses a rotating brush roller to clean, which is difficult to remove strongly adherent dirt. Therefore, a cleaning robot for photovoltaic panels is provided. Utility Model Content
