[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductors to directly convert light energy into electrical energy. The core component is the photovoltaic panel. Over time, dust, bird droppings, and other pollutants accumulate on the surface of photovoltaic panels, corroding the encapsulating glass and blocking sunlight, thus reducing the panel's photoelectric conversion efficiency. Therefore, photovoltaic panels require regular cleaning.

[0003] Typically, cleaning carts use a tracked structure for movement and a motor-driven cleaning roller brush. The travel path is carefully planned to coordinate with the cleaning brush head for cleaning operations. However, existing cleaning carts install the cleaning brush head by manually adjusting the angle and fixing it in place. When encountering protrusions at the joint of two photovoltaic panels, the cleaning brush head may be obstructed, affecting its cleaning effectiveness. Utility Model Content
