Solar automatic cleaning billboard based on rainwater gravity

Abstract

The invention relates to the technical field of solar photovoltaic cell panels, and discloses a solar automatic cleaning billboard based on rainwater gravity, which comprises a support plate, rotatingwheels are rotatably connected to the left and right ends of the support plate, and fixing rods are fixedly mounted on the opposite surfaces of the rotating wheels; cleaning rods are slidably connected to the opposite faces of the fixing rods through buffer springs, and display plates are fixedly installed at the left end and the right end of the support plate. According to the solar automatic cleaning billboard based on the rainwater gravity effect, rainwater falls into a groove in rainy days, a capacitor plate is pressed down due to increase of the amount of rainwater in the groove, the capacitor plate slides downwards, the area opposite to an electrode plate is increased, then an electric signal is transmitted to a driving motor through a wire, and the driving motor drives the rotatingwheels to rotate; and in the rotating process of the rotating wheels, the fixing rods are matched to drive the cleaning rods to move up and down in the guide rail frame, and therefore the billboard cleaning effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic panels, in particular to a solar automatic cleaning notice board based on the gravity of rainwater. Background technique [0002] Solar photovoltaic panel is a device that directly or indirectly converts solar radiation into electrical energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar energy is silicon. Because of the high cost of silicon, solar energy has not been widely developed. , Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly. [0003] At present, some important public notice boards are equipped with solar panels. The installation of the solar panels can provide the public notice boards with light at night, providing people with viewing adjustments. If the public notice boards are installed on the dusty roadside, ...
