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