At present, power lines are usually erected in the wild, which inevitably suffers from the invasion of nature and the impact of human activities for many years, the corrosion of metal accessories and various hardware, illegal buildings, trees, and various accumulations in the line channel, etc. , are unavoidable. In order to ensure the safe and reliable operation of the power line, it is necessary to do a good job in the daily maintenance of the line operation. To find these defects of the line, usually rely on the inspection of the line. The operation and maintenance of the power line generally requires a monthly inspection. In case of strong wind In special circumstances such as heavy rain and failures, it is necessary to temporarily increase the number of inspections, and the inspection of power lines is mainly based on the inspection route on foot, but the inspection route is usually blocked by the growth of plants, especially in mountainous areas. Mountain forests, rugged mountain roads, sparsely populated, the inspection road is very easy to be blocked by thorns, weeds and other plants, making it difficult for the inspectors to move, which reduces the inspection efficiency, increases the labor intensity, and also increases the number of inspection personnel who are hidden in the weeds. Attack and bite hazard of living venomous snakes etc.

For a long time, the line patrol lanes, especially the mountain line patrol lanes, have to hire people to clean and cut plants on the line patrol lanes once or twice every year during the peak growth period of plants from April to August. The line patrol road, because only the branches and leaves above the ground of the plant roots were cut down and cleaned, the roots of the plants were not cleared and eradicated. After less than a month, new branches and leaves were quickly grown again and blocked the line patrol road. It only treated the symptoms but not the root cause. Some plants grow faster and grow more branches and leaves the more they are cut down.
