An outdoor grounding device

Abstract

The invention provides an outdoor grounding device. The outdoor grounding device comprises a base, a shell, a winding cylinder, a clamping ring, a spring, a grounding copper wire and a rotating shaft,wherein the base is detachably arranged on a tower cross arm; the shell is arranged on the base through a fixing mechanism; the rotating shaft is positioned in the shell, and the two ends of the rotating shaft are arranged on the shell separately; the winding cylinder is rotatably arranged on the rotating shaft; a first groove for winding a grounding copper wire is formed in the periphery of thewinding cylinder; the spring is arranged in the winding cylinder to form a spring ring concentric with the winding cylinder; the two ends of the spring are arranged on the winding cylinder and the rotating shaft respectively; the clamping ring is arranged on the inner side of the winding cylinder so as to prevent the spring from falling, and rotates along with the winding cylinder; and a wire passing hole for allowing the grounding copper wire to penetrate through is formed in the shell. According to the outdoor grounding device, the number of the carried working tools can be reduced, the operation procedure is simplified, the working efficiency is improved, the operation difficulty and the operation risk are lowered, and the grounding wire can be protected.

Description

technical field [0001] The invention relates to an outdoor grounding device. Background technique [0002] Most of the power transmission lines are located in remote mountainous areas with high mountains and long roads, so a large amount of work tools and materials need to be carried for power outage maintenance operations. Workers are often exhausted when they arrive on site. When working on the line, it is necessary to conduct electrical inspection and grounding first. The conventional electrical inspection grounding has the following defects: it needs to carry multiple sets of grounding wires, which is very heavy; every time the grounding needs to be carried out, the operator needs to lift the ground on the cross arm of the tower After the work is completed, it needs to be dismantled, bundled and then sent back to the ground. The dismantling process is also unchanged. Therefore, the operation procedure is cumbersome, the workload is heavy, and the work efficiency is redu...

When working on the line, it is necessary to conduct electrical inspection and grounding first. The conventional electrical inspection grounding has the following defects: it needs to carry multiple sets of grounding wires, which is very heavy; every time the grounding needs to be carried out, the operator needs to lift the ground on the cross arm of the tower After the work is completed, it needs to be dismantled, bundled and then sent back to the ground. The dismantling process is also unchanged. Therefore, the operation procedure is cumbersome, the workload is heavy, and the work efficiency is reduced. After the grounding is hung, the grounding copper wire is in a loose and drooping state. It is easy to swing, thereby reducing the safety distance from the lower part or the surrounding charged body, and increasing the operation risk; if the grounding wire is transported and hoisted for a long time, it is easy to wear and tear, which will lead to leakage and other phenomena when grounding, and there are unsafe factors
