This utility model relates to a self-cleaning
solar street light for construction sites, including a light pole, a light body, a photovoltaic panel, and a bracket; it also includes: a slider, slidably connected to the photovoltaic panel, with a
brush at the bottom; an air duct, installed on the slider; a
nozzle, with an air outlet on the air duct corresponding to the
nozzle and connected to the air inlet of the
nozzle; a slider drive mechanism; an
air pump, installed on the light pole, with its air outlet connected to the air duct; and a
control unit, including a controller and a
rain sensor. The advantages are: by setting a
rain sensor, rainwater is used to clean the photovoltaic panel on rainy days. Simultaneously, a nozzle and a push-pull battery iron are added. A strategy is input into the controller to periodically start the
air pump and push-pull battery iron on non-rainy days. After the push-pull battery iron starts, the
brush detaches from the photovoltaic panel, and the nozzle sprays air onto the surface of the photovoltaic panel. During the movement of the slider, the nozzle blows away
dust particles adhering to the surface of the photovoltaic panel, achieving
dry cleaning of the photovoltaic panel.
