Solar panel power generating device de-dusted based on air multiplier

Abstract

The invention relates to a solar panel power generating device de-dusted based on an air multiplier. The device comprises a solar cell panel, a rotating shaft, and a base. The solar cell panel is fixed on the base through the rotating shaft. The rotating shaft consists of a vertical shaft and a horizontal shaft. The device is characterized by further comprising an air multiplier, a support piece, and a control module. The air multiplier sleeves the vertical shaft through the support piece and is fixed above the base, and the air outlet of the air multiplier faces the solar cell panel. The control module controls work of the device. The control module includes a 24V DC power supply, a voltage conversion chip, a single chip microcomputer, a clock chip, an external expanding memory chip, a liquid crystal display, an independent keyboard, and a stepper motor driver. The 24V DC power supply is responsible for supplying power to the stepper motor driver. A 24V voltage is converted by the voltage conversion chip into a 5V voltage for power supply to the single chip microcomputer.

Description

technical field [0001] The invention relates to a solar panel power generation device based on air multiplication and dust removal. Background technique [0002] The dust removal and cleaning requirements for solar panels have increased with the rapid development of solar tracking systems. The application environment of solar panels is complex, and after a period of work, a lot of dust will accumulate on the surface, especially in some places with little rainfall. The accumulation of dust on the photosensitive surface of the solar panel will reduce the conversion efficiency of light, and a small amount (0.00484367821kg / m2) of dust can reduce the energy conversion rate of the solar panel by 40%. The method of manual dust removal has high work intensity and high risk factor, and the cost of hiring workers is also high. Yang Jingfa et al. (Yang Jingfa, Qiu Pengfei, Li Bing, et al.

Problems solved by technology

However, this method uses chemical reagents, which may cause secondary pollution to the environment.

There are also some technologies that use stepping motors to drive roller brushes to clean the dust on the surface of solar panels, but this adds many additional mechanisms to the structure, and the solar tracking system itself has undergone major changes and high costs.
