Abstract
A portable type short-circuit grounding device comprises a grounding clip, an auxiliary hook, a grounding conducting wire and an insulating handle. The grounding clip comprises a clipping base with an upper clipping body, the clipping base is pivotally connected with a crank, one end of the crank is pivotally connected with a lower clipping piece, the clipping base is further equipped with a connecting part which is equipped with an inner threaded hole, one end of the insulating handle can be detachably equipped with an adjusting bolt matching with inner threads, and the upper end of the adjusting bolt is always abutted against the lower end of the crank. When rotating the insulating handle, the crank can upwardly rotate around a first pivot to drive the lower clipping piece to move upwardly, and a conducting bus bar is tightly clipped between clipping planes of the upper clipping body and the lower clipping piece. Because a contact area of the grounding clip and the conducting bus bar is relatively large and the clipping force does not have reverse transmission property, the grounding device is high in grounding reliability. The grounding clip is small in volume and flexible and convenient in use. After completing hanging, the insulating handle can be detached to meet requirements of hanging position and repair space on the site.
