Description

Technical Field

[0002] Transmission lines are an important part of the power system. Safety is very important and is the basis for ensuring the normal operation of the entire power system. Many transmission lines are located in complex environments and densely populated areas, which brings many difficulties to the transmission safety and maintenance of the lines. In particular, transmission lines that are exposed to the wild for a long time are prone to failures, such as cable ice, cable external force damage, insulation oxidation and shedding, etc. These failures can cause line damage and leakage, causing huge losses to personal safety and the economy.

[0003] Ice and impurities on cables in transmission lines are basically cleaned manually or by drone robots. Manual cleaning is inefficient and labor-intensive. Since the middle part of the cables in the transmission lines is suspended in the air, conventional drone robots only spray hot air flows to the transmission lines or apply shaking actions to the cables. The hot air flows and the shaking actions of the cables will cause the cables to vibrate greatly, increasing the connection burden between the two ends of the cables and the transmission towers, and the cleaning effect is not good.
