Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning robots, in particular to a photovoltaic panel cleaning robot with a variable inclination angle. Background Art

[0002] Photovoltaic panels are installed flat or diagonally on the bottom or roof of a building. Due to the natural environment, dust is easily deposited on the panels after a period of time. Photovoltaic panels covered with dust will reduce the power generation efficiency by 20%, so the photovoltaic panels need to be cleaned regularly to ensure the high-efficiency power generation of the photovoltaic panels. Under normal working conditions, the cleaning robot cleans an entire photovoltaic panel, or the cleaning robot crosses multiple photovoltaic panels that are located on the same plane. The cleaning robot has a straight structure. When cleaning the plane, the cleaning robot can evenly clean the area it passes through. However, when the cleaning robot crosses multiple photovoltaic panels and the multiple photovoltaic panels are not located on the same plane, the cleaning will not be clean due to the angle between the photovoltaic panels. In more serious cases, it may hinder the movement of the cleaning robot. Utility Model Content
