Locking type high-voltage ground wire grounding device

Abstract

The invention provides a locking type high-voltage ground wire grounding device, and belongs to the technical field of grounding devices. The locking type high-voltage ground wire grounding device comprises a fixed seat, a connecting assembly and a retaining locking assembly, the fixed seat is used for being connected with a ground grounding grid, the fixed seat is provided with a connecting hole, the inner wall of the connecting hole is provided with an internal thread, the upper end of the fixed seat is provided with an annular tooth-shaped track, and the tooth-shaped track is concentric with the connecting hole and provided with a plurality of teeth evenly distributed in the circumferential direction; the connecting assembly is provided with a connecting rod, the connecting rod is provided with an external thread, the connecting rod is in threaded connection with the connecting hole, and the connecting assembly is provided with a connector structure used for being connected with a grounding wire; and the retaining locking assembly is arranged on the connecting assembly and provided with a clamping piece and an elastic piece, the clamping piece has the degree of freedom of rotating around the middle of the clamping piece, and the elastic piece is used for pushing one end of the clamping piece to be rotationally clamped between the two adjacent teeth so as to prevent the connecting assembly from rotating in the loosening direction. The locking type high-voltage ground wire grounding device provided by the invention has the characteristics of simplicity in operation, reliability and looseness prevention.

Description

technical field [0001] The invention belongs to the technical field of grounding devices, and more specifically relates to a blocking type high-voltage grounding grounding device. Background technique [0002] The grounding wire is an important part to ensure the safety of the circuit and protect the work safety of the circuit maintenance personnel. To a certain extent, the grounding wire can be said to be the life support line of the relevant electric workers. The grounding wires on both sides of the maintenance device can effectively avoid sudden The great harm caused by incoming calls to the human body is an important barrier to protect the life safety of maintenance personnel. [0003] However, the currently used grounding devices have the following disadvantages: the grounding device needs to be tightened and fixed with nuts during use, and the tightening and dismounting of the nuts is time-consuming and labor-intensive; the nut and the bolt pair are prone to misalignme...
