Embodiment 1

[0070] The drone inspects the photovoltaic panels, determines the specific location information of the photovoltaic panel dirt through the infrared camera 102 and the dirt positioning system 101, and then controls the drone to hover within 1 meter of the dirt location, and aims the laser at the stubborn dirt on the photovoltaic panel. Adjust the wavelength to 100nm, and after 5 seconds of working time, the telescopic pipeline 311 is stretched out, so that the rotating nozzle 312 is outside the downwind area of ​​the drone, and then the solenoid valve 302 is started, and the carbon fiber compressed air bottle 301 outputs air, and the air passes through the pressure reducing valve After 303 is decompressed, the outlet pressure is 0.4MPa, so that the air is ejected from the rotating nozzle 312 to clean the impurity gas in the pipeline; adjust the adjustable channel 307 to make the dry ice flow rate 0.2kg / min; after 2s, touch the pneumatic valve 306 When it is turned on, the dry ic...

Embodiment 2

[0072] The drone inspects the photovoltaic panels, determines the specific location information of the photovoltaic panel dirt through the infrared camera 102 and the dirt positioning system 101, and then controls the drone to hover within 1 meter of the dirt location, and aims the laser at the stubborn dirt on the photovoltaic panel. Adjust the wavelength to 3000nm, and after working for 5s, the telescopic pipeline 311 is stretched out, so that the rotating nozzle 312 is outside the downwind area of ​​the drone, and then the solenoid valve 302 is started, and the carbon fiber compressed air bottle 301 outputs air, and the air passes through the pressure reducing valve After 303 is decompressed, the outlet pressure is 0.6MPa, so that the air is ejected from the rotary nozzle 312, and the impurity gas in the pipeline is cleaned; the adjustable channel 307 is adjusted to make the dry ice flow rate 0.3kg / min; after 2s, the pneumatic valve 306 is activated When it is turned on, the...

Embodiment 3

[0074]The drone inspects the photovoltaic panels, determines the specific location information of the photovoltaic panel dirt through the infrared camera 102 and the dirt positioning system 101, and then controls the drone to hover within 1 meter of the dirt location, and aims the laser at the stubborn dirt on the photovoltaic panel. Adjust the wavelength to 1500nm, and after working for 5s, the telescopic pipeline 311 is stretched out, so that the rotating nozzle 312 is outside the downwind area of ​​the drone, and then the solenoid valve 302 is activated, the carbon fiber compressed air bottle 301 outputs air, and the air passes through the pressure reducing valve After 303 is decompressed, the outlet pressure is 0.5MPa, so that the air is ejected from the rotary nozzle 312, and the impurity gas in the pipeline is cleaned; the adjustable channel 307 is adjusted to make the dry ice flow rate 0.25kg / min; after 2s, the pneumatic valve 306 is activated When it is turned on, the d...

Abstract

The invention discloses a method and a system for cleaning stubborn dirt on the surface of a solar photovoltaic panel. The system firstly adopts a laser cleaning technology to strip the stubborn dirt from the surface of the photovoltaic panel, and then cleans the residual dirt in cooperation with a dry ice dirt cleaning technology. Compared with an existing photovoltaic panel decontamination technology, the method is more water-saving, safer, efficient and rapid; a novel 3D printing technology is adopted to process all module frames so as to reduce the load weight of an unmanned aerial vehicle and improve the flight stability of the unmanned aerial vehicle, and the system is simple, safe and easy to operate; the photoelectric conversion rate of the solar photovoltaic panel is improved by removing the stubborn dirt, the hot spot effect is avoided, and the photovoltaic power generation safety is greatly improved; and the system has important significance in reducing water consumption, simplifying cleaning equipment, reducing comprehensive cost, facilitating later maintenance and the like.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic panel power generation, and in particular relates to a cleaning method and system for stubborn dirt on the surface of a solar photovoltaic panel. Background technique [0002] Due to its environmental protection and renewable advantages, photovoltaic power generation has been widely used and developed rapidly in recent years. Solar panels are one of the core components of the photovoltaic power generation system. Generally, they are connected in series and parallel to form a solar panel array, and installed outdoors to receive sunlight and generate electricity. The light receiving efficiency largely determines the performance of the photovoltaic power generation system. power generation efficiency. [0003] Stubborn dirt on solar photovoltaic panels (organic pollution such as shellac and bird droppings, microbial pollution, etc.) is a major difficulty in cleaning photovoltaic panels. I...
