Photovoltaic cell panel cleaning system

Abstract

A photovoltaic cell panel cleaning system disclosed by the present invention comprises a photovoltaic support used for supporting a photovoltaic cell panel, a portal frame body erected at the photovoltaic support and a water supply mechanism used for spraying the cleaning water to the photovoltaic cell panel, and the water supply mechanism comprises a pressure water pipe arranged on the portal frame body, a pressure nozzle connected with the pressure water pipe and used for spraying the cleaning water to the photovoltaic cell panel and a water supply pipe used for transporting the cleaning water to the pressure water pipe. The photovoltaic cell panel cleaning system of the present invention adopts a washing mode to clean the photovoltaic cell panel, the cleaning water sprayed by the pressure nozzle forms a pressure water column under the action of the pressure to spray to the surface of a solar cell panel, and because of a certain water pressure, the stains, such as the floating dust, the guanos, etc., on the surface of the photovoltaic cell panel can be removed very well, and the photovoltaic cell panel can be cleaned thoroughly. The photovoltaic cell panel cleaning system of the present invention is simple and easy, and enables the cleaning efficiency to be improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a photovoltaic panel cleaning system. Background technique [0002] At present, the installed capacity of solar photovoltaic power generation in my country has exceeded 80GW, and most of the projects are distributed in the western region, which is dry, less rainy and dusty. Since the power generation of solar panels depends on the degree of absorption of sunlight, if the surface of the panels is dust According to statistics, the loss of photovoltaic power generation due to surface dust covering is about 8% to 12%, so the dust on the surface of photovoltaic panels will greatly reduce the energy efficiency of the entire power station. [0003] The cleaning of existing photovoltaic panels has the following problems: the photovoltaic power station occupies a large area, the efficiency of manual cleaning is low, the cycle is long, the cost is high, and the quality cann...

AI Technical Summary

Problems solved by technology

[0002] At present, the installed capacity of solar photovoltaic power generation in my country has exceeded 80GW, and most of the projects are distributed in the western region, which is dry, less rainy and dusty. Since the power generation of solar panels depends on the degree of absorption of sunlight, if the surface of the panels is dust According to statistics, the loss of photovoltaic power generation due to surface dust covering is about 8%~12%, so the dust on the surface of photovoltaic panels will greatly reduce the energy efficiency of the entire power station

[0003] The cleaning of existing photovoltaic panels has the following problems: the photovoltaic power station occupies a large area, the efficiency of manual cleaning is low, the cycle is long, the cost is high, and the quality cannot be guaranteed, and the working environment of the workers is poor, which is not conducive to the health of the workers

[0006] (1) Cleaning the photovoltaic panels is achieved by direct contact between the wiper brush and the photovoltaic panel, and the cleaning efficiency is low, and the direct contact between the wiper brush and the photovoltaic panel is easy to cause wear on the photovoltaic panel;

[0007] (2) The support arm of the above cleaning device is set under the photovoltaic panel, and the rainwater and the cleaning water after cleaning the photovoltaic panel are recovered through the groove on the support arm. However, since the cleaning water after cleaning the photovoltaic panel contains a lot of mud When the sand falls directly into the groove, it is easy to make the sand remain in the groove, and the support pulley slides in the groove of the support arm to drive the movement of the wiper brush. Therefore, if a large amount of sand remains in the groove, It is easy to block the groove, so that the support pulley cannot slide on the support arm, that is, it cannot drive the wiper brush to move, thus hindering the wiper brush from cleaning the photovoltaic panel

[0008] To sum up, the cleaning efficiency of the above-mentioned devices is low, and the recycling method of water resources is relatively cumbersome, which is not conducive to the operation of cleaning
