Rotatable multi-angle ground lead and method for controlling opening degree of line clamping opening of rotatable multi-angle ground lead

Abstract

The invention relates to the field of electrical maintenance auxiliary tools, and specifically relates to a rotatable multi-angle ground lead. The rotatable multi-angle ground lead provided by the invention comprises a ground lead head, an insulating rod and an angle adjusting device, wherein the ground lead head and the angle adjusting device are connected through a rotation axis; the ground lead is fixed through hold-down nuts; the ground lead head can rotate on a plane in the horizontal direction of a line clamping opening; and the angle adjusting device is connected with the insulating rod. Moreover, the invention also provides a method for controlling the opening degree of the line clamping opening of the rotatable multi-angle ground lead. A tongue screw and a handle on the insulating rod are connected through a flexible shaft metal wire; the tongue screw is fixedly connected with a movable contact of the line clamping opening; when the handle is rotated, through the transmission of the flexible shaft metal wire, the movable contact of the line clamping opening is pushed upwards or downwards, so that the opening degree of the line clamping opening is controlled. The rotatable multi-angle ground lead can be applicable for various ground points with unreasonable arrangement or insufficient ambient space, is relatively wide in application range, and is more convenient for the connection with the ground points.

Description

technical field [0001] The invention relates to the field of electrical maintenance auxiliary tools, in particular to a rotatable multi-angle grounding wire and a method for controlling the opening of the wire clamp. Background technique [0002] In the maintenance of electrical distribution boxes and power lines, it is often necessary to ground the maintenance equipment to ensure that the circuit equipment is not damaged and to ensure the personal safety of the maintenance personnel. Therefore, it is necessary to use a grounding wire to connect the equipment to the ground. The grounding wire head of the existing grounding wire is directly fixed on the insulating rod. When the space at the grounding point is insufficient, the grounding wire is difficult to be clamped at the grounding point, and the operation is very inconvenient. A modified grounding wire has appeared at present, and an angle adjustment device is added between the grounding wire end and the insulating rod, w...

Problems solved by technology

Although this modification expands the applicable occasions of the ground wire, it still has certain limitations. The direction of the clamp mouth is fixed. For the ground point with dense surrounding lines, it is necessary to rotate the insulating rod so that the wire clamp mouth clamps the ground point. Drive the grounding copper wire to rotate, it is easy to affect the connection of the grounding wire due to insufficient space to rotate or touch other surrounding lines

In addition, due to the addition of the angle adjustment device, the moving contact of the clamp mouth and the rotating handle are not in a straight line. Through the connection between the moving contact and the rotating handle, the opening of the clamp opening cannot be controlled by rotating the handle.
