The present invention relates to a grounding rod structure for preventing electric shock accidents or damage and malfunction of electronic equipment used in an electric use facility, and more specifically, grounding noise and vibration even when installed on a rock or the like when installing the grounding rod in the ground. The present invention relates to a drill blade-shaped ground rod structure that can reduce construction costs and reduce construction costs.

In electrical installations, grounding is the most basic safety device. Inappropriate grounding facilities in electrical installations may cause electric shocks, damage to electronic equipment, and malfunctions. Therefore, it is essential to maintain a complete grounding facility for preventing accidents, protecting expensive equipment, and preventing malfunctions.

According to the guidelines of the Korea Occupational Safety and Health Agency, when installing in places where people may be in contact, such as Jeonju, the grounding electrode should be buried at a depth of 75cm or below. In addition, the specified ground resistance of the pole in which the transformer is installed shall be 25 Ω or less in accordance with the electrical equipment technical standards.

In general, the grounding resistance of the ground rod is easier to secure the ground resistance as deeply buried in the ground as possible, and when it meets a large and large rock in the ground, it cannot penetrate the rock, which is a considerable difficulty in securing the specified ground resistance suitable for the electrical equipment technical standards. I have been.

Accordingly, a ground rod in which a hot dip galvanized ground rod is constructed by a deep perforation method has been proposed, that is, FIG. 3 is a schematic view showing a structure of a conventional multi-stage seam ground rod. The ground rod configuration is connected to the ground wire 10 extending to the ground from the fatigue device installed to protect equipment such as transmission and distribution lines and transformers from lightning, and the end of the ground wire 10 is embedded in the ground, Or it consists of a grounding rod connecting sleeve 30 for connecting the multi-stage grounding rod 20 and the grounding wire 10 and the grounding rod 10 for extending the length by the coupling coupling.

However, in the structure of the conventional multi-stage grounding rod as described above, if a large and large rock is encountered in the ground in the middle of the grounding of the grounding rod 20 for the stern, the rock fails to be crushed and the ground meets the electrical equipment technical standard. It has been a significant difficulty in securing resistance. For example, whether or not rock crushing is normally broken for about 10 minutes by using the Breca rock crushing, but in this case there was a problem that severely generated noise and vibration.

As a result, noise is generated in the process of attempting to crush the rock, which inevitably causes noise pollution to the residents in the city center or near construction sites. In addition, noise and vibration problems, such as cracks caused by vibrations in buildings or walls, and complaints such as compensation, cause the residents to hate electrical installations and oppose the installation of power facilities near buildings. Complaints have been raised, and the structure of the conventional multi-stage grounding rods as described above is not parallel to the rock if it meets a large and large rock in the ground during the burying of the grounding rod 20 As a new grounding electrode should be installed and the grounding work should be done until the specified grounding resistance is obtained, the concrete or asphalt pavement layer on the road must be crushed to excavate the pit wide and large. There are also problems that increase the workload, generate noise, and increase the cost of construction. It was.

An object of the present invention is to solve the conventional problems as described above, and meet the large and large rock in the ground in the ground during the burying of the multi-stage grounding rod for Bream using the Breca can not fracture the rock and electrical equipment technical standards In addition to acting as a significant difficulty in securing a proper grounding resistance suitable for the use, as well as the shape of the drill blade shape of the body of the multi-stage grounding rod for preventing severe noise and vibration when the rock continues to be hit by Breca. The drill rod is a low noise using an electric drill (not shown) instead of the blow method using Breca, and it is a screw or coupling-type drill blade that makes it easy to secure the specified ground resistance by drilling even if it meets rocks in the ground. To provide a shaped ground rod structure.

As a means for achieving the above object, the configuration of the present invention, the processing ground wire is installed to protect the equipment, such as transmission and distribution lines and transformers from lightning, the ground wire extending from the fatigue stage to the ground, and the end of the ground wire It is embedded in the ground by a screw or coupling coupling screw or coupling-type drill blade ground rod to extend the length, and a ground wire connecting sleeve for connecting the lead terminal and the ground wire of the drill blade ground rod In the screw or coupling-type drill blade ground rod, the screw or coupling-type drill blade-shaped ground rod is processed by drilling the body into the shape of the drill blade to drill the rock by using a drill even if the rock meets the ground while installing the ground rod in the ground It is characterized in that the grounding work is very easy.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 is a schematic view showing the structure of the drill rod-shaped grounding rod according to the present invention, Figure 2 is a partial cross-sectional configuration showing the main portion of the present invention separated.

The present invention extends to a processing ground line or an arrester installed to protect devices such as transmission and distribution lines and transformers from lightning strikes, and connects the ground line 100 installed in the underground 500 and the terminal of the ground line 100 to connect the ground. Buried in (500), the lead wire 233 and the ground wire connected to the multi-stage screw or coupling-connected grounding rod 200 and the lead terminal 230 of the grounding rod 200 is extended by a screw or coupling coupling In the screw or coupling-connected grounding rod structure consisting of a grounding wire connecting sleeve 300 for connecting the grounding wire, the grounding rod 200 is drilled around the base portion 210 and the connecting rod 220 constituting its body. 241 is integrally formed to be a perforation facility in the underground rock.

In addition, the conductive portion 400 is filled in order to prevent corrosion of the connection portion between the base portion 210, the connecting rod 220, and the lead terminal 230 constituting the ground rod 200.

On the other hand, Figure 2 is a view showing the separation of the grounding rod 200 according to the present invention, as shown in the drawing, screw or coupling-type drill blade-shaped grounding rod 200 according to an embodiment of the present invention is a mechanical structural carbon A conical tip 211 for penetrating the ground is formed at one end of a drill-shaped steel rod made of steel (KSD 3752) or cemented carbide steel (a) which is a material of a conventional drill blade. The base part 210 which welds and attaches industrial diamond for rock drilling, and the other end forms the coupling threaded rod 213 for screw or coupling connection, and mechanical structural carbon like the said base part 210. Coupling of the base part to be screwed or coupled to the base part 210 to one end of the drill-shaped steel rod made of steel (KSD 3752) or cemented carbide (a) material of the existing drill blade Sabon (2 13 is formed in the same standard as the coupling nut hole 221, a plurality of connecting rods 220 to connect a plurality in series, and carbon steel for the mechanical structure (KSD), such as the base portion 210 A coupling nut hole 231 for screwing or coupling to the connecting rod 220 is formed at one end of the drill rod-shaped steel rod made of the steel a of 3752, and the lead wire 233 at the other end thereof. The lead terminal 230 is made by inserting the.

In addition, the base portion 210, the connecting rod 220 and the outer surface of the lead terminal 230 is subjected to a corrosion treatment by hot dip galvanizing (c), the base portion 210, the connecting rod 220 and the lead The material of the steel (a) of the terminal 230 is preferably made of cemented carbide that is a material of SM45C (mechanical structural carbon steel) or conventional drill blades having a strength that does not change or bend the nature of the steel even when drilling.

As described in the above embodiment, the present invention, unlike the conventional body of the multi-stage shim ground rod and lead terminal is circular, by making a circular body to be processed into a drill blade shape, as in the conventional hammer or hydraulic Breca during the type When a large rock is widely distributed on the ground, it is no longer possible to be struck. Therefore, the grounding work is completed without securing the statutory resistance value according to the Electric Equipment Technology Standard Ordinance. Although the resistance value is secured, if a drill-type ground rod is used, the grounding work is possible until the desired specified resistance is obtained by drilling using a drill even if it meets a rock, and the grounding work is much easier than the current one, and prevents additional parallel work. Thus, the ground construction cost is greatly reduced.

In addition, the present invention has the effect that noise is generated in the process of attempting to break the rock when encountering the rock as in the past, inevitably causes noise pollution inhabitants in the downtown or near construction sites.

In addition, the present invention can solve the problem of civil complaints caused by the damage caused by the vibration when the rock breaks into the Breca due to the vibration, and environmentally friendly grounding is possible to improve the quality of life of the people There is an effect that can be greatly contributed to.
