Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a photovoltaic power generation maintenance and cleaning device. Background Technology
[0002] Photovoltaic panels are devices that convert solar energy into electrical energy using the photoelectric effect. They consist of multiple solar cells; when sunlight shines on a photovoltaic panel, photons excite the semiconductor materials within the cells, generating an electric current. Photovoltaic panels can convert solar energy into electrical energy to supply electricity for homes, businesses, or industries. Cleaning and maintaining photovoltaic panels is crucial for the normal operation of photovoltaic power generation systems and for improving power generation efficiency. Dust, sand, leaves, bird droppings, and other contaminants accumulated on the surface of photovoltaic panels reduce their light absorption capacity, affecting photoelectric conversion efficiency.
[0003] Chinese Patent Publication No. CN116900012A discloses a maintenance device for photovoltaic panels, relating to the field of photovoltaic power generation technology. The device includes a cleaning body and a following vehicle. The cleaning body includes a main mounting plate, with a cleaning plate movably mounted below the main mounting plate. This invention fully utilizes the space left on the front and rear sides of a single-row photovoltaic panel, separately setting up the cleaning body and the following vehicle. A movable locking wheel assembly, in cooperation with a drive wheel, positions the cleaning body on the surface of the photovoltaic panel. The rotation of the drive wheel drives the cleaning body to move, simultaneously moving the following vehicle. While the cleaning body moves, water mist is sprayed from a spray pipe, working with the cleaning plate to clean the surface of the photovoltaic panel. Residual water on the bottom surface of the cleaning plate and the surface of the photovoltaic panel flows down and is collected by a water collection assembly, then recycled to a wastewater tank through a second connecting pipe for water recycling.
[0004] However, the above technical solution has the following defects: the cleaning brush located in the middle of the photovoltaic panel maintenance device cannot effectively cooperate with the toothed belt, the cleaning effect in the middle of the photovoltaic panel is poor and it is inconvenient to use. The cleaning body and the vehicle are connected together, and the two need to move synchronously, otherwise the photovoltaic panel is easily damaged. Utility Model Content
