Technical Field
[0001] This utility model relates to the field of cleaning solar panel photovoltaic equipment, specifically a handheld photovoltaic structure dual-head dual-brush cleaning device. Background Technology
[0002] With the global demand for clean energy growing daily, the cleaning and maintenance of solar panels directly impacts photovoltaic power generation efficiency and power plant revenue. Currently, manual cleaning remains the common method for solar panel maintenance, requiring cleaners to manually wipe away dust, bird droppings, fallen leaves, and other contaminants from each panel surface using handheld cleaning tools. This method is not only extremely inefficient, but also requires significant manpower in large-scale photovoltaic power plants, and poses safety risks such as falls and electric shocks when working at heights. While traditional mechanical cleaning equipment can improve cleaning efficiency to some extent, it still faces many problems in practical applications. Some equipment is bulky and cumbersome, making it difficult to operate flexibly in complex terrains such as mountains and rooftops; some smaller cleaning machines, due to unreasonable design of cleaning components, are unable to thoroughly remove stubborn stains, resulting in inconsistent cleaning effects. Furthermore, existing cleaning equipment generally lacks adaptability when dealing with solar panels installed at different heights and tilt angles. Therefore, developing a solar panel cleaning device that can adapt to complex environments, operate flexibly, and achieve excellent cleaning results has become an urgent industry need. This utility model's handheld dual-brush cleaning device is designed to solve these problems. Summary of the Invention
