Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line inspection, and more specifically, to a multifunctional robot for power transmission line engineering inspection. Background Art

[0002] Electric power transmission must rely on high-voltage transmission lines, whose safe and stable operation directly affects the reliability of the power system. Due to the influence of continuous mechanical tension, electrical flashover, and material aging, they may cause damage such as broken strands, wear, and corrosion. If they are not repaired and replaced in time, the original minor damage and defects may expand, eventually leading to serious accidents and causing large-scale power outages. The existing inspection robots have a simple structure and a single function. They cannot climb over obstacles encountered during inspections, and cannot meet the inspection operations of overhead transmission lines, reducing work efficiency.

[0003] In order to solve the above problems, the utility model patent with announcement number CN214772066U discloses a patrol robot for overhead power transmission lines. When it is necessary to cross an obstacle, the utility model starts a driving motor to drive the threaded rod to rotate, so that the first support frame moves on the threaded rod. When the first support frame moves outward, it drives the connecting column to disengage the connecting column from the slot opened on one side of the second walking wheel, so that the distance between the first support frame and the first support frame becomes larger. During inspection, obstacles can be easily crossed, thereby improving the inspection work efficiency.

[0004] However, when the above-mentioned inspection robot is actually used, when the inspection robot is placed on power transmission lines of different types, the connection between the inspection robot and the power transmission line may not be stable enough, resulting in sliding during movement, which will affect the working safety of the inspection robot.
