Description

Technical Field

[0001] The invention relates to the technical field of power grid construction, and in particular to a foreign matter cleaning device for overhead lines. Background Art

[0002] At present, in order to reduce power supply failures caused by external reasons such as trees, birds and foreign objects and improve the reliability of power supply, bare wire overhead cables that were previously used due to technical and cost issues have begun to be gradually transformed. An insulating layer is applied to the outside of the overhead cables without an insulating layer to avoid power supply failures caused by external reasons such as trees, birds and foreign objects as much as possible, and to enhance the ability of the cables to withstand bad weather. However, since bare wire cables are exposed to the air for a long time, dust accumulates on them or debris such as leaves hang on the cables, which affects the coating effect of the insulating layer. If the foreign objects on the overhead cables can be cleaned before applying the insulating layer, the above problem can be well solved.

[0003] After the cables are hung in the air, it is difficult to clean them manually, and the existing cleaning devices are not convenient to fix on the cables for mobile cleaning, which greatly reduces the efficiency of the cleaning work. It may even cause aging and performance degradation of the cables due to failure to handle them in time.
