[0002] With the development of science and technology, photovoltaic power generation components have been widely used. However, due to the long-term exposure of photovoltaic panels to the outdoor environment, the outermost encapsulation glass is prone to dust accumulation, resulting in reduced light transmittance, which in turn affects the photovoltaic panel's photoelectric conversion efficiency. In addition, in actual photovoltaic power stations, photovoltaic panels are generally arranged in an inclined array. During long-term use, the glass surface of the photovoltaic panel will inevitably be stained with various dust particles and may absorb large garbage, affecting normal photovoltaic power generation, so it needs to be cleaned regularly.

When the proximity switch 305 receives the signal, the mobile motor 203 stops moving to prevent the mobile external frame 1 from falling directly, and ensure that the mobile external frame 1 is located on one side of the photovoltaic panel. At this time, it is convenient to remove the mobile external frame 1. The mobile external frame 1 can be used to directly clean a whole row of spliced ​​photovoltaic panels, and it can move without hindrance.
