Problems solved by technology

[0003] Among the existing patents, the technology closest to the present invention is: the name is, a grounding clip and a suspension grounding wire device and a method for unmanned aerial vehicle suspension grounding wires (application number 202011352304.6); Structurally, the clamps at the tower end and the wire end are hooked downwards, and the UAV is used to suddenly downward, and the whole device is soft, which is basically impossible to achieve in practice, but there is only a theoretical possibility; The second is that the connection of the tower end of the device does not match the shape of the angle steel, so it is difficult to achieve the purpose of clamping and good contact; third, in terms of the operation method, the operation method is to hang the wire end first and then hang the pole tower end, which does not meet the requirements of national security discharge. According to the current standard, there is a risk of electric discharge injury; the method of this patent does not involve the steps of how to use drones for demolition;
[0004] Among the existing patents, there is also an application number of CN201820629684.5, which is named as a grounding wire device for power lines carried by drones. This patent uses a telescopic rod to connect to the high-voltage wire. The telescopic rod is connected to the aircraft through a bracket, which is a rigid connection and requires the aircraft It can only be realized if it is very close to the high-voltage line. There is a risk that the aircraft will hang on the high-voltage line, and there is also a problem of impracticality. The carrying capacity of ordinary aircraft is very limited, usually a few kilograms in weight. The patented telescopic rod needs It is very long to achieve grounding. After the telescopic rod is very long, it needs to be thickened for rigidity, and the weight is heavy. This patent is basically a theoretical possibility, but it cannot be popularized and used in practice, so it is not practical;
