Description

Technical Field

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

[0002] With the progress and development of social life, emergency rescue, and military combat skills, various mobile equipment such as power supply vehicles, communication vehicles, emergency rescue mobile equipment vehicles, radar vehicles, etc. are used more and more frequently. Before these equipment start working in the field, they must first be grounded (workplace, safety ground, and lightning protection ground). In addition to requiring a small grounding resistance, the grounding must also be fast and withdrawn quickly. At present, there is no grounding tool specifically designed for this scenario to achieve rapid grounding and withdrawal. The existing grounding method is basically to bury the grounding copper busbar, grounding rod, etc. after manually digging a grounding pool, or to drive the grounding rod into the ground with a sledgehammer. These grounding methods have the following disadvantages: 1. It is quite difficult to work on hard soil, concrete, etc.; 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. Summary of the invention

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should belong to the scope of protection of the present invention.

[0026] Example

[0027] like Figure 1 As shown, the present invention relates to a grounding rod, which comprises a grounding rod handle 2, a grounding rod body 1 and a grounding rod head 3. The top of the grounding rod body 1 is connected to the grounding rod handle 2, and the bottom of the grounding rod body 1 is connected to the grounding rod head 3, and the three are formed in one piece.

[0028] The grounding rod body 1 is made of special steel rod, which has the characteristics of high hardness, not easy to deform, corrosion resistance, wear resistance, etc. The grounding rod body 1 is provided with a protruding spiral texture 6, which is the optimal design after comprehensive verification of a large number of soil characteristics and chip discharge rates. The spiral texture includes a coarse thread 61 and a fine thread 62 connected to each other in sequence, and the grooves between adjacent spiral texture tracks constitute a chip discharge groove 63, which is used to discharge soil chips when grounding.

[0029] The grounding rod head 3 is arranged at one end of the grounding rod body 1 and is used to be inserted into the ground with a hardness of concrete soil. In this embodiment, as a preferred solution, the grounding rod head 3 is composed of a four-edged steel knife structure 4 arranged in a cross, such as Figure 2As shown, specifically, the four-blade steel knife structure 4 includes two main steel knife heads 41 and two auxiliary steel knife heads 42. The two identical steel knife heads are arranged correspondingly. The four steel knife heads are arranged in a cross shape and stand upright on a knife head base 43. The knife head base 43 is a flat plate structure. The cross-arranged four-blade knife heads can fully meet the hardness requirements of concrete soil grounding operations.

[0030] The grounding rod handle 2 is arranged at the other end of the grounding rod body 1, and is used to connect with the electric hammer or install the grounding cap. The grounding rod handle 2 is provided with a grounding rod slot 5 for accurately installing the electric hammer or the grounding cap. In this embodiment, the grounding rod handle 2 is a cylindrical structure, and its outer diameter is smaller than the outer diameter of the grounding rod body 1.

[0031] In this embodiment, the grounding rod slot 5 includes a handle center slot 51, a handle right slot 52, a handle left slot 53, a handle right pit 54 and a handle left pit 55. The grounding rod handle 2 is a cylindrical structure. In this embodiment. Figure 3 As shown, the front 1 / 4 arc surface of the grounding rod handle 2 is provided with a handle right groove 52 and a handle left groove 53; the left and right corresponding arc surfaces of the grounding rod handle 2 are symmetrically provided with a handle left pit 55 and a handle right pit 54; the rear 1 / 4 arc surface of the grounding rod handle 2 is provided with a handle center groove 51. The handle center groove 51, the handle right groove 52, and the handle left groove 53 are all designed as long strip elliptical grooves, one end of the handle right groove 52 and the handle left groove 53 is provided at the top of the grounding rod handle 2, and the other end is provided at the center of the handle body of the grounding rod handle 2. The handle right pit 54 and the handle left pit 55 are long strip structures. The structure of the grounding rod handle 2 and its grounding rod slot 5 is actually adapted to a high-power electric hammer, which can be used to drive into the ground with a hardness of concrete.

[0032] The ground rod body 1 is connected to the ground rod head 3 and is provided with a chip feed groove 7 on its lower outer wall. As a preferred solution, a plurality of chip feed grooves 7 are arranged at equal intervals on the lower outer wall of the ground rod body 1.

[0033] A grounding cap can also be installed on the grounding rod handle 2 of the grounding rod after it is driven into the ground. The resistance of the grounding rod head 3 and the grounding rod handle 2 at both ends of the grounding rod body 1 is less than 0.4 ohms. When a smaller grounding resistance is required, several grounding rods can be driven within one meter. Multiple grounding rods are connected in parallel through grounding caps.

[0034] In actual use, the grounding rod can be quickly driven into the ground by utilizing the hammer rotation function of the electric hammer and the spiral texture of the grounding rod. Specifically, the handle of the grounding rod is installed in the hammer head mounting hole of the electric hammer, and the blade head of the grounding rod head can penetrate hard clay, stones in clay, and even reinforced concrete floors. When the grounding rod needs to be pulled out, the electric hammer can be rotated or a grounding cap can be installed on the handle of the grounding rod, and the grounding rod can be pulled out by rotating the round rod through the auxiliary hole of the grounding cap. In addition, when a smaller grounding resistance is required, several more grounding rods can be driven within one meter, and multiple grounding rods can be connected in parallel through grounding caps.

[0035] The grounding rod of the present invention can replace the manual knocking method by combining the electric method of the electric hammer. The drill bit of the electric hammer is replaced by the grounding rod. The grounding rod includes a grounding rod body, a grounding rod head and a grounding rod handle. The grounding rod body is provided with a spiral texture. Through the electric rotation of the electric hammer, the difficulty of ground operations on hard soil, concrete and the like can be greatly reduced. It has strong versatility, convenient operation, fast grounding and good effect, and can effectively improve the convenience of temporary grounding. It is suitable for outdoor sites where frequent replacement of power construction is required. The grounding rod head is composed of four-edged special steel knives arranged in a cross, which can improve the efficiency of hammering into the ground and fully meet the grounding operation requirements of soil with a hardness of concrete.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
