Description

Technical Field

[0001] This application relates to the technical field of cable maintenance, and particularly to an ice removal device for cable lines. Background Art

[0002] ‌As the core infrastructure of the power system, power transmission towers are tower structures made of high-strength steel. Their main function is to support overhead transmission lines and achieve the safe and reliable transmission of electrical energy from power plants to end-users. Through unique structural designs, such special towers can ensure the efficient long-distance transmission of large-capacity electrical energy under complex terrains and extreme climate conditions.

[0003] ‌Transmission cables are interconnected and transmitted through high-altitude erection at the top of the towers. However, under cold climate conditions, ice is likely to form on the surface of the cables. This ice accumulation will not only significantly increase the vertical load of the conductors, but also change the mechanical properties and electrical characteristics of the conductors. In severe cases, it may cause safety hazards such as mechanical overload and reduced insulation performance, threatening the stability of the power grid operation.

[0004] The current mainstream UAV ice removal technology has significant technical bottlenecks: First, the insufficient ice removal force leads to low operation efficiency; second, restricted by visual recognition accuracy and spatial positioning technology, it is difficult to achieve accurate ice removal position calibration. These technical defects not only increase the work intensity of ground operators, but also may pose a continuous threat to the safety of the power grid due to incomplete ice removal and the risk of secondary icing.
