Description

Technical Field

[0001] This utility model relates to the technical field of grounding electrodes for lightning rods or equipment in power, railway, construction and petrochemical industries, and in particular to a spherical alloy anti-corrosion grounding device. Background Technology

[0002] Grounding electrodes are used to discharge lightning current, static electricity, working ground, protective ground, safety and unbalanced current, etc., and can stabilize potential, which is extremely important for ensuring the safety of equipment and personnel.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Traditional grounding electrodes, such as metal grounding plates or metal grounding rods, can meet certain usage requirements. However, they still have the following technical problems: Metal grounding rods, due to their shape limitations, have a small contact area with the soil, making them susceptible to external environmental factors such as geographical environment, soil conditions, and seasonal changes. This leads to large fluctuations in soil moisture, resulting in substandard grounding electrode resistance in various grounding grids and posing safety hazards to equipment and facilities. Furthermore, due to limitations in on-site construction conditions, traditional grounding electrodes generally have poor corrosion resistance, accelerating the corrosion rate and significantly reducing grounding reliability.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a spherical alloy anti-corrosion grounding device to solve the technical problem that existing grounding electrode designs have defects, such as a small contact area with the soil, making them susceptible to external environmental factors, resulting in large fluctuations in soil moisture, and consequently, substandard resistance and safety hazards. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1 As shown, this utility model provides a spherical alloy anti-corrosion grounding device, including a grounding body 1, a lead-out component 2 and a grounding wire 3. The grounding body 1 is a hollow spherical structure. The grounding body 1 is connected to the grounding wire 3 through the lead-out component 2. The cavity of the grounding body 1 is filled with a conductive solution 13, and several through holes 14 are opened at its lower part for the conductive solution 13 to diffuse to the external environment.

[0023] The grounding body 1 adopts a spherical structure, which has a larger surface area compared to a grounding rod, increasing the contact area with the soil, resulting in a larger current dissipation area and stronger current carrying capacity. Furthermore, the grounding body 1 is filled with a conductive solution 13, which is slowly released into the surrounding soil through through-holes 14, enhancing the soil's conductivity and more effectively reducing grounding resistance. Moreover, the design of the lead-out component 2 allows the grounding body 1 to be easily connected to the grounding wire 3, providing more reliable grounding protection for equipment and personnel. This invention is particularly suitable for use in locations requiring reliable grounding protection, such as power systems, rail transit, airports, and communication base stations.

[0024] Furthermore, the grounding body 1 is made of alloy material, which has high strength and corrosion resistance.

[0025] As an optional implementation, the grounding body 1 includes an upper housing 11 and a lower housing 12, which are sealed and fastened together to form a receiving cavity.

[0026] The grounding body 1 adopts a split design, which facilitates manufacturing, assembly, disassembly and maintenance.

[0027] As an alternative implementation, the lead-out component 2 is disposed on the top of the upper housing 11.

[0028] The function of lead-out component 2 is to enable the grounding body 1 to be easily connected to the grounding system and provide reliable grounding protection.

[0029] As an alternative implementation, the through hole 14 is provided in the lower part of the lower housing 12.

[0030] The number of through holes 14 can be set to five, six or more according to the usage requirements, so that the conductive solution 13 can be fully diffused into the surrounding soil through the through holes 14, and play the roles of lightning protection grounding, AC / DC working grounding, anti-static grounding and safety protection grounding.

[0031] As an optional implementation, the grounding body 1 is filled with energy storage filler 6 between itself and the external environment.

[0032] Furthermore, the energy storage filler 6 includes hydroxyethyl cellulose, montmorillonite powder, and water-absorbing resin.

[0033] After the grounding body 1 is placed in the pit, the gap between the grounding body 1 and the surrounding soil is filled with energy storage filler 6. This arrangement, in conjunction with the conductive solution 13, disperses the solution into the surrounding soil, serving functions such as lightning protection grounding, AC / DC working grounding, anti-static grounding, and safety protection grounding, further stabilizing the resistivity of the surrounding soil. Furthermore, the energy storage filler 6 absorbs moisture and stores energy during the rainy season or rainy days, and releases moisture in winter or dry weather to improve the resistivity of the surrounding soil, reducing the impact of weather and season on the grounding resistance.

[0034] As an optional implementation, a filling assembly 4 is also included, which communicates with the receiving cavity through the lead-out assembly 2.

[0035] Furthermore, the filling assembly 4 has a filling channel that communicates with the receiving cavity. The conductive solution 13 enters the receiving cavity through the filling channel of the filling assembly 4, making operation convenient.

[0036] After filling is completed, the filling channel of filling component 4 can be sealed with a sealant to improve safety and sealing.

[0037] As an optional implementation, a conductive anti-corrosion layer 5 is provided on the outer side of the grounding body 1.

[0038] Furthermore, the conductive anti-corrosion layer 5 is an alloyed anti-corrosion layer, which has strong current carrying capacity and good corrosion resistance. It is not easily damaged during construction and daily operation, providing reliable protection for the long-term safe operation of the grounding grid. Moreover, it reduces the impact of drought and seasonal changes on grounding resistance, ensuring stable grounding grid resistance values.

[0039] It should be noted that the specific materials of the grounding body 1, conductive solution 13, conductive anti-corrosion layer 5 and energy storage filler 6 are based on existing technologies, as long as they can perform the above functions, which will not be elaborated here.

[0040] The grounding system is connected to the earth by a grounding device. The grounding current is introduced into the grounding body 1 through the grounding wire 3 and then dissipated to the surrounding soil through the conductive anti-corrosion layer 5 and the conductive solution 13, thus playing the roles of lightning protection grounding, AC / DC working grounding, anti-static grounding and safety protection grounding.

[0041] This invention can be used as an auxiliary device to work in conjunction with other existing grounding systems to improve grounding effectiveness. It can also be used independently to construct a corrosion-resistant grounding grid, reducing grounding resistance and enhancing grounding capacity. It can serve as a grounding electrode in power systems, rail transit, airports, communication base stations, and other similar locations.
