Abstract

Aiming at the flexible and safe cleaning of photovoltaic modules, an omnidirectional mobile photovoltaic cleaning robot configuration is designed. The rationality of the robot configuration is determined by using the four-wheel differential modeling method and the wheel set electromagnetic braking analysis. In view of the limitations of the existing mobile cleaning methods, a new synchronous cleaning method of roller brush dedusting and pipeline dust suction is studied. Through the CFD simulation method, the flow field simulation model of the robot suction pipe and cleaning mechanism is established, and the cleaning characteristics analysis and structural optimization simulation of the structural model are completed, as well as the comparison and evaluation test of the actual cleaning effect. The test results show that the designed cleaning robot can achieve 86.5% cleaning efficiency and improve the motion braking capability.
