China State Construction Engineering Corporation’s Eighth Bureau has obtained a patent for a dust removal mechanism designed for solar photovoltaic panels, enhancing cleaning efficiency. According to information from the National Intellectual Property Administration, the patent titled “A Dust Removal Mechanism for Solar Photovoltaic Panels” was officially granted with announcement number CN222776182U, and the application date was June 2024.
The patent summary indicates that this innovative utility model relates to solar power generation technology. It features a cleaning frame with a hook-shaped frame fixedly connected to its right side via a support. Within the cavity of the hook-shaped frame, a first resistance wheel is rotatably connected between its top and bottom with several such wheels installed. Additionally, a load-bearing rod is also rotatably connected within the right side of the hook-shaped frame, positioned between two first resistance wheels.
This utility model is designed to improve cleaning efficiency by incorporating a wiping board and a dragging frame inside the cleaning frame, which work in conjunction with a spray nozzle and a scraper. Operators can push the equipment to first scrape off solidified dirt from the photovoltaic panels using the scraper, followed by spraying water and wiping with the wiping board. This design allows a single operator to effectively clean the panels, thus reducing labor costs.
Founded in 2009 and located in Dalian, China State Construction Engineering Corporation’s Eighth Bureau is primarily engaged in the construction industry, with a registered capital of 150 million RMB. According to data analysis from Tianyancha, the company has invested in 15 enterprises and participated in 62 bidding projects. It holds 9 trademark registrations, 90 patents, and has obtained 27 administrative licenses.
