The working principle is as follows: when the high-voltage transmission grounding misoperation preventing device is used, firstly, the device is installed at a designated position, then the sealing plate 30 and the plug board 5 are disassembled from one side of the control box 1, the grounding wire of high-voltage transmission is butted with the cable end 31, the cable end 31 is inserted into the threading groove 3 and clamped with the connecting groove 29 at the inner side of the fixing seat 28, then the matched locking connecting piece sequentially penetrates through the cable end 31, the lead bar 26 and the fixing seat 28, so that the grounding wire of high-voltage transmission is butted and fixed with the device, then the plug board 5 is spliced with the bulge 4 at the edge of the threading groove 3 through the clamping groove 6, so that the plug board 5 extrudes the grounding wire of the cable end 31 in the threading groove 3, and the waterproof protection is carried out on the connecting position of the grounding wire through the installation and fixation of the sealing plate 30 at one side of the control box 1, one end of a ground wire row 20 penetrates the bottom of the control box 1 to extend into the bottom of the control box 1, so that the one end of the ground wire row 20 is butted with the inside of the connecting seat 16, meanwhile, the connecting frame 22 on one side of the ground wire row 20 drives the arc-shaped clamping plate 24 to be clamped with the butting rod 25 inside the groove 21, so that the clamping plate 24 clamps the butting rod 25 in a rotating way around the rotating shaft 23, so that the device is stably butted with the ground wire row 20 connected to the ground, and then the hand wheel 11 on one side of the control box 1 is rotated to drive the first bevel gear 12 at one end of the transmission wheel 8 to be meshed with the second bevel gear 13 inside the control box 1, so that the second bevel gear 13 drives the screw 14 to rotate in the sleeve 18 with the assistance of the fixing frame 15, and because the sleeve 18 is connected with the through hole 17 inside the connecting seat 16 in a penetrating way, the rotating screw 14 drives the clamping seat 19 at the bottom end, when the clamping seat 19 and the ground wire bar 20 are clamped and fastened, the ground wire bar 20 and the device can be stably installed and connected in an anti-falling mode, after the high-voltage power transmission ground wire is butted, the knob screw 705 in the locking mechanism 7 is rotated, the knob screw 705 drives the side plate 703 in the sliding groove 704 on the inner side surface of the control box 1 to move up and down, meanwhile, the side plate 703 moving up and down drives the limiting rod 702 to extend and retract in the guide hole 701 at the top end of the control box 1, when the bottom end of the limiting rod 702 is plugged with the limiting hole 10 in the middle of the butting plate 9, the spring 706 is used for damping, the limiting rod 702 limits the rotation of the driving wheel 8 in the limiting hole 10, so that the handwheel 11 outside the control box 1 is prevented from being rotated and operated mistakenly, and further the electrical connection among the ground wire bar 20, the lead bar 26 and the cable end 31 is effectively prevented from being, the internal components of the device can be serviced and maintained by the access cover 2 on top of the control box 1 and the separation of the earth connection and the operation control can be performed by the partition 27 inside the control box 1, which is not described in detail in this description and is known to the person skilled in the art. The vertical distribution means that the positional relationship between the two members is a vertical relationship.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
