Description

Technical Field

[0002] Photovoltaic panels are devices that generate direct current electricity when exposed to sunlight. They offer advantages such as energy conservation and emission reduction, environmental friendliness, and significant economic benefits. However, due to long-term exposure to outdoor conditions, the surface of photovoltaic panels becomes covered with dust, significantly reducing the effective contact area between the panels and sunlight, thus affecting their power generation efficiency.

The device comprises a light stand, a lamp connected to one side of the light stand, and a mounting bracket tilted at the upper end of the light stand for securing the photovoltaic panel. The device also comprises a dust removal unit disposed at the upper end of the mounting bracket. The dust removal unit comprises a dust removal assembly, which includes a brush mechanism for scrubbing dust off the photovoltaic panel and a blower mechanism disposed to one side of the brush mechanism for drying the scrubbed photovoltaic panel. As the brush mechanism moves upward along the photovoltaic panel, it draws water from a water storage unit and sprays it onto the surface of the photovoltaic panel, thereby flushing and brushing off dust adhering to the panel. As the brush mechanism moves downward along the photovoltaic panel, a trigger assembly controls the brush mechanism to stop spraying water and activates the blower mechanism to dry any remaining water on the photovoltaic panel, thereby cleaning dust adhering to the panel.
