To effectively solve the problem of dust coverage on the surface of photovoltaic panels and improve the photovoltaic conversion efficiency of photovoltaic power plants,an intelligent cleaning robot for photovoltaic panels was designed based on the current installation environment of photovoltaic panels.The robot was composed of a walking mechanism,a cleaning mechanism,a control module,and various sensors,and could perform cleaning work independently on a photovoltaic panel.The walking mechanism and cleaning mechanism of the robot were designed and calculated,then the stability conditions of the robo′s motion were obtained through mechanical analysis.Combining with the robot′s functions,the control system of the robot was designed.Finally,a robot prototype was produced.Through motion and cleaning performance testing of the robot,it can stably move on an inclined plane below 25°;cleaning agencies have good cleaning capabilities for floating dust or scale buildup,and robots can recognize edges and independently complete cleaning tasks.Compared with traditional cleaning methods,it not only solves the problem of dust coverage on photovoltaic panels,but also greatly reduces labor costs and water waste.
