Design of Overhead Ground Wire Repair Robot Based on Unmanned Aerial Vehicles

In response to the current issue of the inability to accurately transport overhead ground wire repair robots to repair points and efficiently repair broken and loose ground wires, this paper designs an overhead ground wire repair robot based on unmanned aerial vehicle. Firstly, the mechanical structure of the overhead ground wire repair robot was selected and de-signed to achieve information transmission and collaborative operation of various modules; Then, the dual closed-loop PID control method is used to control the stable position and posture of the drone, achieving the drone’s tracking of the robot’s position. At the same time, the mechanical structure and control method of the drone’s detachment device are designed to co-operate with the overhead ground wire repair robot, ensuring the accurate completion of the repair operation; Finally, a prototype of an aerial ground wire repair robot based on drones was developed and successfully applied to the repair of broken aerial ground wires in towers 66-67 of the 500kV Jiangzi Line in Ya’an, verifying the excellent engineering application value of the unmanned aerial ground wire repair robot studied in this paper.
