[0001] The invention belongs to the technical field of power distribution line maintenance, and in particular relates to a foreign matter cleaning device for a power distribution line. Background Art

[0002] The safe and stable operation of transmission lines directly affects the safety and reliability of the power system. Transmission lines are exposed to complex and harsh environments in the wild for a long time and are seriously affected by external factors. Kites, plastic bags, hydrogen balloons, wishing lanterns, etc. are often hung on the transmission lines. If they are not cleaned in time, short circuits between phases are likely to occur, which will have a serious impact on the safe operation of the transmission lines. For transmission lines that cross rivers, forests, farmlands, and are high above the ground, it is difficult for boom trucks to enter the operating area, and it is extremely difficult to manually clean foreign objects on the transmission lines.

[0003] In the prior art, there is a cleaning device with a cutting mechanism that can travel on the transmission line to clean the foreign objects entangled on the transmission line. However, due to the influence of the working environment, the cleaning device at high altitude is easily affected by external factors when traveling, such as strong wind and other weather conditions, which may cause the cleaning device to tilt or even have the risk of falling, which not only affects the cleaning effect but also poses a safety hazard.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a foreign body cleaning device for distribution lines. Summary of the invention

[0007] Furthermore, the linear drive device adopts an electric push rod.
