Description

Technical Field

[0002] The lightning protection inspection of high-rise buildings includes multiple inspection items such as lightning current measurement, grounding system test, metal component insulation test, lightning rod test and lightning induction test. A key link of the above inspection items is to lay out and reel in the wires from the roof. At present, the laying out and reeling in the lightning protection inspection of high-rise buildings have the following problems: 1. The distance of laying out the wires from the roof to the ground is long, and the weight of the wires is heavy. In addition, the natural wind makes the cables swing left and right, which causes the operators who lay out the wires to be subjected to a large downward pulling force during the laying out and reeling out process, posing a safety hazard to the operators who lay out the wires on the roof of the high-rise building. At the same time, it is also impossible to lay out the connecting wires at a uniform speed and slowly, and the reeling out process requires a high arm strength of the operators; 2. Secondly, during the process of laying out and reeling out the wires, the copper stranded wires are prone to friction with the parapet or lightning strip, which will cause wear on the copper stranded wires, and there is a high temperature hazard caused by friction; 3. After the laying out of the wires, there is no effective cable fixing measure, and the cable reel is light in weight. The cables, equipment and reels connected to the detection equipment on the roof are at risk of being pulled off the roof. Utility Model Content
