Electric micro water cleaning head for solar panel

Abstract

The invention discloses an electric micro water cleaning head for a solar panel. The electric micro water cleaning head comprises a machine frame, a broken filament brush roller, a damp brush roller, a dry brush roller, a plurality of hard dirt scraping plates and a plurality of rubber water scraping plates. The two ends of the broken filament brush roller, the two ends of the damp brush roller and the two ends of the dry brush roller are fixed to the machine frame. The end portions of the broken filament roller, the damp roller and the dry roller are each provided with a transmission wheel. Speed reduction motors are further fixedly arranged on the machine frame. Transmission wheels are arranged on the speed reduction motors. The transmission wheels of all the brush rollers are matched with the transmission wheels on the speed reduction motors, and therefore all the brush rollers can be driven by the speed reduction motors to rotate, and the electric micro water cleaning head for the solar panel is driven by an external drive device to move. The electric micro water cleaning head for the solar panel is used in cooperation with a mechanical arm of a vehicle for cleaning the solar panel, the cleaning work efficiency of large solar power generation field photovoltaic cell panels is greatly improved, a small amount of water is used, no water stains are left, and the 0.5 MW solar cell panel can be cleaned each hour.

Description

technical field [0001] The invention relates to a solar panel cleaning device, in particular to an electric micro-water cleaning head for a solar panel. Background technique [0002] At present, the earth can use less and less energy, but solar energy is an inexhaustible energy source. As a clean and pollution-free new energy source, solar energy has attracted extensive attention in recent years, especially in the fields of photovoltaic power generation and photothermal power generation. . However, when photovoltaic panels and heliostats (hereinafter collectively referred to as solar panels) are exposed to the atmosphere, they will accumulate dust and form gray spots, which will reduce the conversion efficiency of solar energy by 20%-40%. Partial coverage of photovoltaic panels by bird droppings and falling objects will cause light spots The thermal effect will damage the photovoltaic panels; when the solar panels are covered by snow, they cannot generate electricity, and i...

Problems solved by technology

The solar panel dust removal device disclosed in Chinese patents 200710172457.0 and 201110399677.3 is a car wiper structure. The dust removal action span is small and there are dead angles. It is not suitable for the large solar panels with a width of 4 meters and a height of 20 meters in my country, and it is not suitable for the 100 square meters of the Spanish PSA and PS10. Sun Mirror; 201110289151.X discloses a plan that is installed on the slideway on both sides of each solar panel, and the crossbeam equipped with dust and snow removal strips is driven by a motor to remove dust and snow from one end of the solar panel to the other end. The average cost of this solution is high, and the slideways and screw rods are prone to rust in the sun and rain, making it difficult to implement

At present, the "overflow flushing method", "self-cleaning glass" made of titanium dioxide, "photocatalyst", "new glass anti-corrosion coating" and "manual cleaning" are used at home and abroad to design methods around a single photovoltaic panel or heliostat , the first four methods all require more water, and it is difficult to use them in desert areas where water is scarce

"Manual cleaning" has the problems of low efficiency and high cost. According to actual research, a 3MW solar power station is cleaned twice a month, and the annual cleaning labor cost is 1 million yuan
