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. After the surface of the grounding rod is corroded, the grounding resistance is too high to meet the grounding resistance requirements

Embodiment

[0027] Such as figure 1 As shown, the present invention relates to a ground rod, which includes a ground rod handle 2 , a ground rod body 1 and a ground rod head 3 . The top of the ground rod body 1 is connected to the ground rod handle 2, and the bottom of the ground rod body 1 is connected to the ground rod head 3, and the three are integrally formed.

[0028] The grounding rod body 1 is made of special steel rod, which has the characteristics of high hardness, not easily deformed, corrosion resistance and wear resistance. The ground rod body 1 is provided with a protruding spiral texture 6, which is an optimal design after comprehensive verification of a large number of soil properties and chip yield. The spiral texture includes coarse threads 61 and fine threads 62 arranged in sequence, and grooves between adjacent spiral texture tracks form chip removal grooves 63 for discharging soil debris when grounding.

[0029] The ground rod head 3 is arranged at one end of the gr...

Abstract

The invention relates to a grounding rod. The grounding rod comprises a grounding rod body (1), a grounding rod handle part (2) used for mounting an electric hammer or a grounding cap, and a groundingrod head part (3) used for being inserted into the ground. The grounding rod handle part (2) and the grounding rod head part (3) are arranged at two ends of the grounding rod body (1); and the grounding rod body (1) is provided with protruding spiral textures (6), the grounding rod handle part (2) is provided with a grounding rod groove position (5) used for being matched with electric hammer installation or grounding cap installation, and the grounding rod head part (3) is a four-blade steel knife structure (4) arranged in a crossed mode. Compared with the prior art, the grounding rod is rapid in grounding, capable of achieving small grounding resistance grounding and improving efficiency of hammering into the ground, convenient to carry and the so on.

Description

technical field [0001] The invention relates to the technical field of grounding equipment, in particular to a grounding rod. 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 wi...
