Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, in particular to a cleaning robot for a full-automatic photovoltaic panel. Background Technique

[0002] A photovoltaic panel is a photoelectric semiconductor thin sheet that directly generates electricity using sunlight. A single solar cell cannot be directly used as a power source. To be used as a power source, several single solar cells must be connected in series and parallel and tightly encapsulated into a module. The photovoltaic panel is a key component for solar energy conversion. Since the solar photovoltaic panel is exposed outdoors, it is easy to accumulate dust, which affects the entry of sunlight, thereby weakening the power generation capacity of the photovoltaic panel. Therefore, it is necessary to clean the surface of the photovoltaic panel in a timely manner.

[0003] During the use of existing cleaning equipment for photovoltaic panels, the existing robot cleaning equipment is expensive and cannot clean photovoltaic panels with large installation angles. Therefore, it does not meet the existing requirements. For this reason, we propose a cleaning robot for a full-automatic photovoltaic panel with low cost, wide adaptability, strong performance, and programmability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cleaning robot for a full-automatic photovoltaic panel, so as to solve the problems in the existing cleaning equipment for photovoltaic panels during use, such as the high price of the existing robot cleaning equipment and the inability to clean photovoltaic panels with large installation angles.
