[0002] Line maintenance refers to the work carried out on power transmission lines based on problems found during inspections, tests, and tests, aiming to eliminate defects, improve equipment health, prevent accidents, and ensure safe operation of the lines. It is a term used in the power industry. Currently, most of the existing line maintenance devices are carried out on high-altitude cables, and power construction workers wear safety belts. Due to the long maintenance lines, it is difficult for power construction workers to perform maintenance, which is time-consuming and labor-intensive, and cannot meet the needs of line maintenance.

[0003] According to a Chinese patent, a portable line maintenance device is disclosed, and its announcement number is: CN211209119U. This patent is to solve the problem that most of the existing line maintenance devices are carried out on high-altitude cables, and the power construction personnel wear safety belts. Due to the long maintenance line, the power construction personnel have difficulty in maintenance, which is time-consuming and labor-intensive, and cannot meet the needs of line maintenance. The utility model can make it more convenient for power construction personnel to repair the line by setting a card seat, a drive motor, a rotating shaft and an insulating wheel, saving time and labor, and meeting the needs of line maintenance;

[0004] However, the patent only protects the construction workers through safety ropes and safety buckles, which makes it easy for the construction workers to fall from the insulating base, posing a great safety hazard. Therefore, we propose a power transmission and distribution line fault inspection and repair device with a protective structure. Utility Model Content
