AI Technical Summary

Technical Problem

When existing photovoltaic cleaning robots clean bird droppings and dried polymers on the surface of photovoltaic panels, the conventional cleaning process often results in poor cleaning performance and secondary pollution because the roller brush easily adheres to the dirt and the scraper easily pushes away the dirt.

Method used

The dry-hanging photovoltaic cleaning robot, which employs a structure with resistance scraping and negative pressure adsorption, scrapes off dirt with a scraper and adsorbs it into the negative suction chamber under negative pressure. Combined with the elastic drive of the spiral spring, it achieves automated unloading.

Benefits of technology

It effectively scrapes and absorbs dirt, preventing stains from tangling and shifting, ensuring cleaning results and reducing cleaning costs.

Abstract

The application discloses a dry-hanging photovoltaic cleaning robot, and relates to the technical field of photovoltaic cleaning robots.The dry-hanging photovoltaic cleaning robot comprises a shell, pulleys arranged on both sides of the shell, guide rails fixed in the shell, connecting blocks slidingly assembled on the guide rails, shaft rods penetrating the connecting blocks, roller brushes and rotating wheels respectively assembled on both ends of the shaft rods, scrapers arranged at the bottom of the rotating wheels, and collecting boxes arranged adjacent to the rotating wheels, wherein the rotating wheels further comprise sliding grooves arranged on the surfaces of the rotating wheels.The roller brushes of the existing photovoltaic cleaning robot adopt a flexible brush structure, and softened bird droppings and polymers are prone to adhere to and wind around the brush hairs, and are difficult to fall off by themselves, which not only affects the continuous cleaning effect, but also easily causes secondary pollution.If a scraper is simply used to directly scrape off the softened stains, the scraper will push the softened stains forward as a whole, and the bird droppings and polymers are easily pushed to the originally clean photovoltaic panel area, thereby expanding the pollution range, increasing the subsequent cleaning difficulty and cleaning cost.
