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

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 ele
