Portable quick grounding device

Abstract

The invention relates to a portable quick grounding device. The device comprises an electric hammer, a grounding rod and a lap joint cap. The grounding rod comprises a grounding rod body, a groundingrod head part and a grounding rod handle part, wherein the grounding rod head part and the grounding rod handle part are arranged at two ends of the grounding rod body. The ground rod body is providedwith spiral textures. The grounding rod handle part is arranged in a hammer head mounting hole of the electric hammer in a grounding and withdrawing operation state, the lap joint cap is mounted on the grounding rod handle part in a grounding state, and a positioning mechanism for stabilizing the grounding rod handle part and an auxiliary mechanism for withdrawing the grounding rod from the ground are arranged on the lap joint cap. Compared with the prior art, the grounding device has advantages of quick grounding, reusable parts, convenience in carrying and the like.

Description

technical field [0001] The invention relates to a grounding device, in particular to a portable fast grounding device. Background technique [0002] With the progress and development of social life, emergency rescue, and military combat technology, various mobile equipment such as power supply vehicles, communication vehicles, emergency rescue mobile equipment vehicles, and radar vehicles are used more and more frequently. Before starting work in the field, these equipment first need to be grounded (working ground, safety ground and lightning protection ground). The grounding requires a small grounding resistance, fast grounding and quick withdrawal. At present, there is no grounding tool specially designed for this scenario to implement rapid grounding and withdrawal. The existing grounding methods are basically to bury the grounding copper bars and grounding rods after manually digging the grounding pool, or to drive the grounding rods into the ground by hitting with a sl...

Problems solved by technology

The existing grounding methods are basically to bury the grounding copper bars and grounding rods after manually digging the grounding pool, or to drive the grounding rods into the ground by hitting with a sledgehammer. These grounding methods have the following disadvantages: 1. Hard soil, It is quite difficult to work on concrete and other ground; 2. The grounding operation takes a long time; 3. It is difficult and time-consuming to withdraw the grounding, or the grounding rod cannot be reused; 4. The grounding resistance after the surface of the grounding rod is corroded is too high to meet the grounding resistance requirements
