Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and in particular to a composite structure slow-release ion grounding device. Background Technology

[0002] Slow-release ion grounding devices are a type of resistance-reducing material with stable grounding performance and high resistance-reduction efficiency, and are currently widely used in grounding projects. Commercially available slow-release ion grounding devices typically consist of a metal tube, outer filler, inner filler, and connecting wires. The inner filler is mainly composed of active ion materials and is housed within the metal tube. Its working principle is to improve the soil resistivity around the grounding electrode (metal tube) by slowly releasing ions, thereby reducing the grounding resistance of the grounding electrode.

[0003] The service life of a slow-release ion grounding device is primarily related to the corrosion resistance of the metal pipe. The inner cavity of the metal pipe contains a high-concentration ion-rich filler. Once these ions come into contact with the metal, they accelerate corrosion; the higher the ion concentration, the stronger the corrosion, especially for carbon steel and hot-dip galvanized steel. After burial, the outer wall of the metal pipe suffers not only from soil corrosion but also from the intense corrosion caused by ions released from the filler. Furthermore, damage to the inner anti-corrosion layer also poses a risk of accelerated corrosion. Patents CN201853823U and CN204156111U propose a three-layer structure for the metal pipe to address the corrosion resistance issues of the inner and outer walls. The three-layer structure of patent CN201853823U consists of an inner cavity coated with a polymer material, a middle layer of carbon steel, and an outer layer of stainless steel. Due to manufacturing processes (mechanical extrusion bonding and internal cavity assembly) and damage to the outer layer during construction (such as scratches), the three-layer structure is prone to interlayer voids and even coating gaps. Ions containing the internal filler can quickly enter, leading to accelerated corrosion of the carbon steel in the middle layer and posing a risk of insufficient service life. Patent CN204156111U's three-layer structure still uses carbon steel for the middle layer, while the inner and outer wall coatings are made of titanium metal covering the steel pipe surface. Besides having the same corrosion risks as CN201853823U, titanium metal is also expensive, making it uneconomical.

[0004] Therefore, it is necessary to develop a composite structure slow-release ion grounding device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to design a composite structure slow-release ion grounding device to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A composite structure slow-release ion grounding device, comprising:

[0008] Connecting wire; the first end of the connecting wire is connected to the main grounding grid;

[0009] Metal grounding electrode; the second end of the connecting wire is connected to the upper end of the metal grounding electrode;

[0010] Non-metallic container; the non-metallic container is filled with internal packing material, and the side wall of the non-metallic container is connected to a metal grounding electrode; the upper part of the side wall of the non-metallic container is provided with multiple water absorption holes, and the lower part of the side wall of the non-metallic container is provided with multiple ion slow-release liquid outlet holes.

[0011] The beneficial effects of this utility model are as follows:

[0012] This application uses a non-metallic container to fill the inner packing material, so that the metal grounding electrode does not come into contact with the inner packing material. At the same time, the ions in the inner packing material are not released around the metal grounding electrode, but are released towards the soil surface. After the ions diffuse into the surrounding soil, their concentration is greatly reduced, and the corrosion of the metal grounding electrode is also weakened. In this way, the metal grounding electrode can be selected and designed according to the soil corrosivity of the grounding area, avoiding insufficient or excessive design, which may lead to failure of grounding resistance reduction effect or increase in project investment.

[0022] like Figure 1 As shown, a composite structure slow-release ion grounding device includes:

[0023] Connecting wire 1; the first end of connecting wire 1 is connected to the main grounding grid;

[0024] Metal grounding electrode 2; the second end of connecting wire 1 is connected to the upper end of metal grounding electrode 2;

[0025] Non-metallic container 3; the non-metallic container 3 is filled with internal packing 4, and the side wall of the non-metallic container 3 is connected to the metal grounding electrode 2; the upper part of the side wall of the non-metallic container 3 is provided with three water absorption holes 31, and the lower part of the side wall of the non-metallic container 3 is provided with three ion slow-release liquid outlet holes 32.

[0026] In some embodiments, the three water suction holes 31 are arranged on the same horizontal plane. The angle formed by the line connecting any two adjacent water suction holes 31 to the vertical axis of the non-metallic container 3 is the same, which is 90°. The water suction hole 31 located in the middle is placed on the back side of the connection between the metal grounding electrode 2 and the non-metallic container 3.

[0027] In some embodiments, the three ion-releasing liquid outlets 32 are arranged on the same horizontal plane. The angle formed by the line connecting any two adjacent ion-releasing liquid outlets 32 and the vertical axis of the non-metallic container 3 is the same, which is 90°. The ion-releasing liquid outlet 32 ​​located in the middle is positioned on the back side of the connection between the metal grounding electrode 2 and the non-metallic container 3.

[0028] In some embodiments, the non-metallic container 3 is formed into a cylindrical or spherical structure. The material can be selected from conductive rubber, PVC, or PE.

[0029] In some embodiments, the metal grounding electrode 2 is formed as a cylindrical (tubular or rod-shaped) or plate-shaped structure. The material can be copper, copper-clad steel, zinc-clad steel, stainless steel, or hot-dip galvanized steel.

[0030] Because the three ion-releasing holes 32 are not oriented towards the metal grounding electrode 2, this application can both improve the soil resistivity of the grounding electrode periodically by releasing ions and reduce the corrosion of the metal grounding electrode 2 by the inner filler 4.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
