Embodiment 1

[0059] The drone inspects the photovoltaic panel, and determines the specific location information of the photovoltaic panel stain through the infrared camera 402 and the stain positioning device 401. The operator controls the drone to hover within 1 meter near the stain position, and aligns the nozzle 203 on the photovoltaic panel. Stains, adjust the plunger pump 204 flow rate to 2L / min, the working time is 5 seconds, start the plunger pump 204, so that the cleaning liquid is sprayed from the nozzle 203; after the plunger pump stops working for 5 seconds, first open the solenoid valve 302, adjust The outlet pressure of the carbon fiber compressed air bottle pressure reducing valve 303 is 0.4MPa so that the compressed air passes through the inlet of the spray boom gas pipeline 309 and is sprayed out from the nozzle 312 to clean the impurity gas in the pipeline; adjust the adjustable channel to make the dry ice flow rate 0.2 kg / min; After 2 seconds, touch the pneumatic valve 306...

Embodiment 2

[0061] The unmanned aerial vehicle inspects the photovoltaic panels, and determines the specific location information of the photovoltaic panel stains through the infrared image acquisition device 402 and the stain positioning device 401. For stains on the board, adjust the flow rate of the plunger pump 204 to 3L / min, and the working time is 5 seconds, start the plunger pump 204, so that the cleaning liquid is sprayed from the nozzle 203; after the plunger pump stops working for 5 seconds, first open the solenoid valve 302 , adjust the outlet pressure of the carbon fiber compressed air bottle pressure reducing valve 303 to 0.5MPa so that the compressed air passes through the inlet of the spray boom gas pipeline 309 and is sprayed out from the nozzle 312 to clean the impurity gas in the pipeline; adjust the adjustable channel to make the dry ice flow After 2 seconds, touch the pneumatic valve 306 to open, and the dry ice particles enter the dry ice inlet 309 of the spray bar thr...

Abstract

The invention provides a method and system for cleaning a panel surface of a solar photovoltaic panel with dry ice. Compared with an existing photovoltaic panel decontamination technology, the method and the system for cleaning the panel surface of the solar photovoltaic panel with the dry ice have the advantages that an environment-friendly stain cleaning agent is adopted to be sprayed to the panel surface of the solar photovoltaic panel, and meanwhile, a dry ice cleaning technology is used in cooperation, so that residual stains are cleaned away without water stains, and the problem of water shortage in regions such as deserts or gobi is solved. Compared with an existing photovoltaic panel cleaning technology, more water is saved, cleaning is higher in efficiency, faster and more thorough, a novel 3d printing technology is adopted, the load weight of an unmanned aerial vehicle is reduced, the flight stability of the unmanned aerial vehicle is improved, the system is simple, safe and easy to operate, the photoelectric conversion rate of the solar photovoltaic panel is improved, and the cleaning cost is reduced.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic panel power generation, and in particular relates to a method and system for cleaning the surface of a solar photovoltaic panel with dry ice. Background technique [0002] With the advancement of technology in recent years, photovoltaic power generation has been widely used and developed rapidly due to its environmental protection and renewable advantages, and the cost per unit energy of existing solar power generation has dropped significantly to the level of thermal power generation. Because large-scale solar photovoltaic power plants are often distributed in sparsely populated areas such as open deserts and Gobi, solar photovoltaic panels are placed in exposed harsh environments for a long time, and their surfaces will be polluted by sandstorms, ice, and bird droppings. The heat conversion rate is greatly reduced, and because the polluted part cannot work normally, the temperature is too high ...
