Abstract： The traditional insulator cleaning method is very dangerous， effortless， time-consuming and low efficiency. In order to solve these problems， the type， radius， installation location and angle of different insulators were analyzed. A new design of the manipulator used in the semi-automatic cleaning robot was proposed， which can break the sweeping angle limitation and achieve 360°all-round cleaning. The all type insulators cleaning were realized through the stretching of the sweeping arm， the rotation and tilt of the brush， and the opening and closing adjustments of the gripper. The results indicate that， this new design of the manipulator can replace the traditional manual cleaning very well， which make the cleaning work safer， improve the cleaning efficiency and ensure the quality of the cleaning.
