Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel cleaning, and in particular to an engineering photovoltaic panel cleaning device and a working method thereof. Background Art

[0002] Solar panels refer to devices that use the photovoltaic effect of semiconductor materials under lighting conditions to directly convert solar energy into electrical energy. When photovoltaic power generation is carried out, a large number of photovoltaic panels will be used. The cleanliness of the surface of photovoltaic panels has a great impact on the power generation. In an open-air use environment, if the surface of the photovoltaic panels is not cleaned for a long time, a large amount of dust and various stains will accumulate on the surface of the photovoltaic panels, which will block the sunlight and reduce the power generation efficiency.

[0003] Announcement No.: CN218499102U, named: A photovoltaic panel cleaning device, including a bracket, a photovoltaic panel and a scraping assembly, the scraping assembly including a mounting plate, a slide, a scraper, a driving component and an auxiliary component. When the photovoltaic panel has not been cleaned for a long time, a certain amount of cleaning liquid stains will remain on the surface of the photovoltaic panel, which will affect the irradiation of the photovoltaic panel and reduce the power generation efficiency. At this time, the driving component can be controlled to move, and the driving component movement will drive the slide to move back and forth, thereby driving the scraper to move back and forth, scraping the surface of the photovoltaic panel to remove the liquid stains on the surface, and then realizing that when the photovoltaic panel has not been cleaned for a long time, the liquid stains on the surface of the photovoltaic panel can be automatically cleaned, greatly reducing the amount of manual labor, and is more conducive to the rapid cleaning of the photovoltaic panel.

[0004] The above-mentioned existing photovoltaic panel cleaning device is easily limited by the installation angle of the photovoltaic panel when in use. The photovoltaic panels are usually placed at an angle of 30°-45° in various regions. When the tilt angle is too small, the pollutants generated by the upper cleaning are likely to remain on the photovoltaic panel, thereby further affecting the normal use of the photovoltaic panel. In addition, the photovoltaic panel and the cleaning device are mostly assembled together for use, which is difficult to disassemble independently, and it is not convenient to use one cleaning device to clean different photovoltaic panels. For this reason, an engineering photovoltaic panel cleaning device and a working method thereof are provided. Summary of the invention
