Solar cell panel cleaning device

Abstract

The invention relates to a solar cell panel cleaning device. The solar cell panel cleaning device comprises a water pipe support, wherein the water pipe support is arranged at the top of a solar cellpanel; a crank rocker mechanism is connected below the water pipe support; one end of a rocker of the crank rocker mechanism is connected with the water pipe support, and the other end is connected toa disc-shaped crank; the disc-shaped crank is connected with an electric transmission device; and the water pipe support is connected with a row of nozzles which are tightly attached to the plane ofthe solar cell panel through a water pipe, wherein a certain angle is formed between the nozzles and the plane of the solar cell panel. The fluid ejected by the high-pressure nozzles has great momentum, and has high dust removal and descaling effects on dust and shielding objects on the surface of the cell panel; the equal-interval and swing type nozzles can enable water flow to pass through relatively large cell panels, so that the cleaning efficiency can be improved; and therefore the cleanliness of the surface of the solar cell panel can be ensured, the occurrence of "hot spot effect" is reduced, the photoelectric conversion efficiency is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a solar battery panel, in particular to a solar battery panel cleaning device. Background technique [0002] Solar cell modules are usually installed in areas with open areas and plenty of sunlight. During long-term use, it is inevitable that flying birds, dust, fallen leaves and other shelters will fall on them, and these shelters will form shadows on the solar cell modules. Due to the existence of partial shadows, the current and voltage of some single cells in the solar cell module have changed. As a result, the product of the local current and voltage of the solar cell modules increases, thereby generating a local temperature rise on these cell modules. Defects of some cell monoliths in the solar cell module may also cause local heating of the module during operation. This phenomenon is called "hot spot effect". In the actual use of solar cells, if the temperature generated by the hot spot effect exceeds a certain limit,...

AI Technical Summary

Problems solved by technology

In the actual use of solar cells, if the temperature generated by the hot spot effect exceeds a certain limit, the solder joints on the cell components will be melted and the grid lines will be destroyed, resulting in the scrapping of the entire solar cell component

[0003] The research on solar panel cleaning mainly focuses on the dust removal on the surface of the solar panel through the wiper arm and the transmission device, while there is less research on the use of jets from medium and high pressure nozzles to clean the surface of the solar panel
