And a ground wire hooking step, namely releasing the ground wire disassembling and fixing assembly so that the ground wire disassembling and fixing assembly moves downwards to the ground relative to the wire clamping and fixing assembly, fixing one end wire clamp of the ground wire, fixing and locking the other end of the ground wire with the ground wire disassembling and fixing assembly, moving the ground wire disassembling and fixing assembly with the ground wire upwards to the wire clamping and fixing assembly, and locking the ground wire clamping and fixing assembly to realize the grounding of the wire.

15. The method of claim 14, wherein the releasing the ground wire securing assembly moves the ground wire securing assembly downward to the ground surface relative to the wire clamping assembly, in particular:

and lifting the ground wire unlocking rope, releasing the locking of the ground wire unlocking piece on the ground wire clamping hook, and releasing the ground wire clamping hook under the traction of the weight piece, so that the ground wire clamping hook moves downwards to the ground.

16. The method for attaching and detaching the ground wire according to claim 14 or 15, wherein the ground wire detaching assembly moves the ground wire up to the wire clamping assembly and is locked on the wire clamping assembly, specifically:

and the traction rope is pulled, so that the traction rope pulls the ground wire clamping hook to be lifted upwards between the right clamping block and the left clamping block, and the ground wire unlocking rope is released, so that the right clamping block and the left clamping block relatively move to clamp and lock the ground wire clamping hook.

17. The ground wire hitching method as recited in claim 14 or 15, further comprising, after said ground wire hitching step, the steps of:

and in the disassembling step, the ground wire disassembling and fixing assembly is released, so that the ground wire disassembling and fixing assembly carries the ground wire to move downwards to the ground relative to the wire clamping and fixing assembly, the locking of the ground wire and the ground wire disassembling and fixing assembly is disassembled, the ground wire disassembling and fixing assembly is driven to move upwards to the wire clamping and fixing assembly and lock relative to the wire clamping and fixing assembly, the wire clamping and fixing assembly is hung and taken by an unmanned aerial vehicle, and the ground wire disassembling and fixing assembly takes off and lands and carries the wire clamping and fixing assembly and the ground wire disassembling and fixing assembly, so that the ground wire is disassembled.
