Description

Technical Field

[0001] The present invention relates to the technical field of lightning protection device detection, and more specifically, to a lightning protection device detection system based on an unmanned aerial vehicle. Background Art

[0002] In the existing technology, the inspection of roof lightning protection facilities usually requires workers to climb to the roof in person to check the installation dimensions of the grid, lightning strip and down conductor, as well as the corrosion of the metal grid. However, this traditional method has the problems of low efficiency and potential safety hazards, especially for those roof areas that are difficult to reach or potentially dangerous.

[0003] Although a lightning protection device detection device based on a drone has been developed in the prior art to improve detection efficiency and safety, this device still faces some technical challenges in practical applications. One of the most notable problems is that during the flight of the drone, the lead wire connected to the resistance tester may be pulled. This pulling force may come from the high-speed flight of the drone, wind speed, obstacles in the flight path, or the maneuvering action of the drone. Long-term pulling may cause damage to the lead wire or even breakage, thereby affecting the accuracy and reliability of the resistance test.

[0004] In addition, damage to the lead wires may also cause failure of the resistance tester, which not only increases the cost of repair and replacement, but may also affect the progress of the entire detection task. Therefore, how to protect the lead wires from damage and ensure the stability and reliability of the UAV when performing lightning protection device detection tasks is one of the key issues that need to be solved in current UAV lightning protection detection technology. Summary of the invention

[0005] 1. Technical issues to be solved
