Description

Technical Field

[0001] The present invention belongs to the technical field of distribution network inspection, and in particular, relates to an automatic distribution network inspection system based on an unmanned aerial vehicle. Background Art

[0002] With the huge demand for electricity, the entire power system has been under tremendous pressure. It is necessary to inspect the lines in the overall distribution network system in a timely manner to avoid problems such as line aging and cracking, and to ensure the normal operation of the lines. At present, the inspection of distribution network lines is generally still carried out by manual inspection, which is not only very dangerous, but also has a relatively low inspection efficiency. Some devices that use drone inspections generally take photos and observe at a certain distance from the line, resulting in inaccurate line inspections.

[0003] Application No.: CN202411533473.8 discloses a drone for inspection of distribution network lines. The drone is connected to the inspection mechanism through an elastic rope, and the tension of the elastic rope is transmitted to the drone for feedback to adjust its posture in time. At the same time, the design of the inspection mechanism and the positioning clamp used to clamp the inspection mechanism makes the separation and combination of the inspection mechanism and the line more flexible and convenient. A hanger structure is arranged at the bottom of the drone. During the landing process, the drone relies on the hanger for support and has poor stability. During the drone inspection, the external facilities of the power system are mainly monitored and evaluated to ensure the safety and stability of power transmission. The inspection objects include transmission lines, power towers, substations, distribution facilities, etc., to check whether the lines are broken, tilted, rusted, etc., and observe whether the insulators are damaged. The setting of the U-shaped inspection cover will limit the location of the inspection and detection, resulting in a limited scope of use of the drone inspection.
