AI Technical Summary

Technical Problem

Existing wheeled de-icing robots have complex obstacle avoidance structures, weak mobility, and cannot flexibly cross obstacles such as load-bearing ropes or suspension devices.

Method used

Design a robot dog that can lift and traverse obstacles and remove ice from overhead power transmission lines. It adopts a multi-link transmission assembly and a clamping assembly. The robot's stepping motion on the power line is achieved by the periodic swing of the clamping assembly. The gripper group can bypass or cross obstacles, and the de-icing operation is achieved by combining de-icing blades and auxiliary propulsion blades.

Benefits of technology

It enables robots to move stably and remove ice efficiently on power lines. It has a simple obstacle avoidance structure, strong passage ability, and can move continuously and effectively remove ice.

Abstract

This invention relates to a robotic dog for overcoming obstacles and removing ice from suspended power transmission lines. The robotic dog comprises a robot body, a multi-link transmission assembly, and a gripping assembly. Multi-link transmission assemblies are located on both sides of the robot body. A drive source is located within the robot body and connected to the multi-link transmission assemblies, driving the multi-link transmission assemblies to swing. The gripping assembly is rotatably mounted at one end of the multi-link transmission assemblies, and its end has a gripper assembly for gripping the power line. The multi-link transmission assemblies drive the gripping assembly to swing periodically, enabling the robot body to move stepwise along the power line. When the robot encounters an obstacle during this stepwise movement, it rotates the gripping assembly so that the gripper assembly can bypass the load-bearing rope or cross the obstacle. The obstacle avoidance structure is simple, and the robot has strong mobility.
