Device for hanging or detaching grounding wire of high-voltage line by aircraft and use method

Abstract

The invention relates to a device for hanging or detaching a grounding wire of a high-voltage line by an aircraft and a use method. The device is used for inductive discharge between tower angle steel on a high-voltage tower and a high-voltage line; the device comprises a grounding device clamped with tower angle steel, a high-voltage line clamping device clamped with the high-voltage line, and an aircraft; and the grounding device is connected to the high-voltage line clamping device through a wire. The grounding device comprises an inverted U-shaped grounding guide rail, a proximity switch, a guide column and a baffle plate; one end of the guide column is provided with a first magnet, the baffle plate is provided with a second magnet, the aircraft is provided with a retractable connecting rope, and the connecting rope is provided with a hook; and the hook is connected to a hanging ring. The high-voltage line clamping device comprises a first clamping body, a second clamping body, a torsion spring and an electric push rod. The device has the beneficial effects that: through the arrangement of the device for hanging or detaching the high-voltage line grounding wire by the aircraft, induced electricity in the high-voltage line is connected to a tower through a wire to discharge to the ground.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance in the electric power industry, in particular to a device for hanging or removing a grounding wire of a high-voltage line for an aircraft and a method for using it. Background technique [0002] At present, before the maintenance of the high-voltage line, in order to avoid the induction electric injury in the high-voltage line, the maintenance workers usually climb the pole tower and connect a clamp to the high-voltage line through the insulating rod. There are operational risks such as falling from high altitude and electric shock. People need to carry more than 20 kilograms of grounding wires when they climb tens of meters or hundreds of meters. The labor intensity of the operators is high. productive forces; [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...

[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;
