Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a grounding electrode cone and grounding method. Background Technology

[0002] In the field of power equipment grounding, the grounding electrode is a key component whose performance is significantly affected by the geological environment. Traditional grounding electrodes have exposed many problems under harsh geological conditions.

[0003] After the grounding electrode cone is installed, water is usually added around it to reduce the resistance to below the testing standard (≤10Ω). However, in arid and hot environments, such as the Gobi Desert, water evaporates quickly and is easily absorbed, causing the grounding resistance to gradually increase, leading to inaccurate test data or even failure to detect open circuits. During emergency rescue and repair in the Gobi Desert, the need for reliable grounding devices is even more urgent, and traditional grounding electrodes are difficult to meet the requirements.

[0004] Traditional grounding electrodes have the following prominent problems in harsh geological environments:

[0005] Low resistance reduction efficiency: Conventional vertical grounding electrodes are used in dry or highly saline-alkali soils where the soil conductivity is poor, making it difficult to reduce the grounding resistance to the standard range, which increases the risk of power system failure.

[0006] Installation is complex: Installation in rocky areas requires pre-drilling, which is difficult and may damage the environment; in soft areas such as deserts, the grounding is easily loosened, and manual hammering is inefficient and cannot meet the requirements for rapid installation.

[0007] Poor adaptability: The injection of existing grounding electrode resistance reducing agent relies on special tools, which are inconvenient to operate in complex field environments and make it difficult to achieve rapid and effective resistance reduction.

[0008] Furthermore, existing technologies have not solved the core problems of low detection efficiency and slow emergency deployment, making it impossible to quickly establish an effective grounding system in emergency situations. Therefore, there is an urgent need for a grounding device that combines high resistance reduction, rapid installation, and convenient testing functions. Summary of the Invention

[0009] The purpose of this invention is to provide a grounding electrode cone and grounding method to solve the problems existing in the prior art. The first cavity inside the cone body contains a resistance-reducing agent, which continuously enters the ground layer through the drainage hole at the tip, effectively and continuously maintaining the grounding resistance value within the standard range. At the same time, the hammer-driven structure facilitates rapid installation, achieving efficient resistance reduction, rapid installation, and convenient testing functions.

[0010] To achieve the above objectives, the present invention provides the following solution:

[0011] This invention provides a grounding electrode cone, comprising a cone body, a tip, and a hammering structure. The cone body has a first cavity inside, and its two ends are a first port and a second port connected to the first cavity, respectively. The tip is connected to the second port of the cone body, and the tip has a second cavity inside, which is connected to the first cavity. A drainage hole connected to the second cavity is formed on the wall of the tip. The hammering structure is connected to the outer wall of the cone body, and the hammering surface of the hammering structure is located outside the axial projection area of ​​the first port of the cone body.

[0012] In one embodiment, the hammering structure includes a support portion and a hammering portion. The support portion is connected to the ground cone body and has an angle with the ground cone body. The hammering portion is connected to the support portion, and the top surface of the hammering portion serves as the hammering surface.

[0013] In one embodiment, a grounding connector is also included, one end of which is connected to the outer wall of the ground cone body, and the other end of which is a free end.

[0014] In one embodiment, the grounding connector includes a main body and an enlarged portion connected to each other, the main body being connected to the ground cone body, and the diameter of the enlarged portion being larger than the diameter of the main body.

[0015] In one embodiment, a handrail is also included, which is connected to the outer wall of the ground cone body.

[0016] In one embodiment, the handrail includes a horizontal support arm and an oblique support arm connected to each other. The horizontal support arm is vertically connected to the ground cone body, and the oblique support arm is obliquely connected to the ground cone body. The horizontal support arm, the oblique support arm, and the ground cone body are combined to form a right triangle.

[0017] In one embodiment, a top plug is also included, the top plug comprising a plugging portion and a first threaded portion connected to each other, the first port being a threaded port, and the first threaded portion being used for threaded connection with the threaded port.

[0018] In one embodiment, the top plug pin further includes an extension, one end of which is connected to the first threaded portion, and the other end of which is used to extend to a position close to the second cavity.

[0019] In one embodiment, an injection interface is further included, which is used to connect the injection bottle and the first cavity. The injection interface includes a through port and a second threaded portion connected to each other. The second threaded portion is used to be threadedly connected to the threaded port, and the through port is used to connect to the bottle mouth of the injection bottle.

[0020] This invention provides a grounding method using a grounding electrode cone as described above, including the following:

[0021] S1. Strike the hammer face to drive the grounding electrode cone into the ground to the set depth;

[0022] S2. Inject a drag-reducing agent into the first cavity of the ground cone body, and allow the drag-reducing agent to penetrate into the surrounding soil layer through the drainage hole;

[0023] S3. Connect the grounding wire to the ground cone body.

[0024] The present invention achieves the following technical effects compared to the prior art:

[0025] This invention utilizes a first cavity within the ground cone body to contain a resistance-reducing agent. The agent can enter a second cavity connected to the tip of the first cavity and then continuously enter the ground layer through a drainage hole connected to the second cavity. This reduces the resistance value of the ground layer at the insertion location of the ground cone body, effectively and continuously maintaining the grounding resistance value within the standard range. Simultaneously, the ground cone body can be quickly installed by striking the hammering surface of the hammering structure. Furthermore, the hammering structure and the first port of the ground cone body do not overlap in the projection area of ​​the ground cone body, avoiding obstruction of the first port by the hammering structure. The resistance-reducing agent can be intermittently or continuously replenished to the first port, ultimately achieving efficient resistance reduction, rapid installation, and convenient testing functions.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The purpose of this invention is to provide a grounding electrode cone and grounding method to solve the problems existing in the prior art. The first cavity inside the cone body contains a resistance-reducing agent, which continuously enters the ground layer through the drainage hole at the tip, effectively and continuously maintaining the grounding resistance value within the standard range. At the same time, the hammer-driven structure facilitates rapid installation, achieving efficient resistance reduction, rapid installation, and convenient testing functions.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-6As shown, this invention provides a grounding electrode cone, comprising a cone body 1, a tip 6, and a hammering structure 2. The cone body 1 has a first cavity inside, with a first port and a second port at its two ends, respectively, connecting to the first cavity. Thus, the cone body 1 can be a cylindrical structure with both ends open. The first cavity can hold a resistance-reducing agent, the first port serves as an inlet, and the second port serves as an outlet. The tip 6 is connected to the second port of the cone body 1. The tip 6 is designed for easy insertion into the ground. The tip 6 has a second cavity inside, connecting to the first cavity. Both the first and second cavities can serve as a space for holding the resistance-reducing agent. A drainage hole 61, connecting to the second cavity, is provided on the wall of the tip 6. The resistance-reducing agent in the first and second cavities can be drained through the drainage hole 61. Since the tip 6 is inserted into the ground during use, the resistance-reducing agent can seep into the ground through the drainage hole 61, thereby reducing the resistance at the grounding electrode cone location. The hammering structure 2 is connected to the outer wall of the ground cone body 1. By hammering the hammering structure 2, the ground cone body 1 can be inserted into the stratum. The hammering surface of the hammering structure 2 is located outside the projection area of ​​the first port in the axial direction of the ground cone body 1. That is, the projection of the hammering structure 2 and the first port in the axial direction of the ground cone body 1 do not coincide. Thus, the hammering structure 2 can make room for the position of the first port to avoid interference. At the same time, it can also avoid damaging the first port by hammering, which would affect the injection of the drag-reducing agent.

[0043] This invention utilizes a first cavity within the ground cone body 1 to contain a resistance-reducing agent. The resistance-reducing agent in the first cavity can enter a second cavity connected to the tip 6, and then continuously enter the ground layer through a drainage hole 61 connected to the second cavity. This reduces the resistance value of the ground layer at the insertion position of the ground cone body 1, effectively and continuously maintaining the grounding resistance value within the standard range. Simultaneously, the ground cone body 1 can be quickly installed by striking the hammering surface of the hammering structure 2. Furthermore, the hammering structure 2 and the first port of the ground cone body 1 do not overlap in the projection area of ​​the ground cone body 1, which avoids the hammering structure 2 blocking the first port. The resistance-reducing agent can be intermittently or continuously replenished to the first port, ultimately achieving efficient resistance reduction, rapid installation, and convenient testing functions.

[0044] In one implementation, such as Figure 1 , Figure 2 and Figure 4As shown, the hammering structure 2 includes a support part 21 and a hammering part 22. The support part 21 is connected to the ground cone body 1 and forms an angle with the ground cone body 1. This angle allows the support part 21 to be angled upwards when the tip 6 is pointing downwards. The hammering part 22 is connected to the support part 21, which supports the hammering part 22. Simultaneously, the angle (less than 90°) between the ground cone body 1 and the support part 21 ensures that the force transmitted by the hammering part 22 has a component along the axial direction of the ground cone body 1. Therefore, when the hammering part 22 is struck, the ground cone body 1 can be smoothly inserted into the stratum. The top surface of the hammering part 22 serves as the hammering surface, which has sufficient contact area, facilitating accurate hammer placement during hammering and improving operational convenience.

[0045] In one implementation, such as Figure 1 and Figure 3 As shown, it also includes a grounding connector 4. One end of the grounding connector 4 is connected to the outer wall of the ground cone body 1, which can be done by welding or threading, but the grounding connector 4 must be in reliable contact with the ground cone body 1. The other end of the grounding connector 4 is a free end, and the grounding wire can be wound and connected to the grounding connector 4 for fixation. The grounding connector 4 can also be provided with a through hole for the grounding wire to pass through.

[0046] In one implementation, such as Figure 3 As shown, the grounding connector 4 includes a main body 41 and an enlarged portion 42 connected to each other. The main body 41 is connected to the ground cone body 1. The diameter of the enlarged portion 42 is larger than the diameter of the main body 41. Therefore, when the grounding wire is wound around and connected to the main body 41, the enlarged portion 42 can be used to restrict the position of the grounding wire and prevent it from falling off. By providing the enlarged portion 42, the connection and fixing effect of the grounding connector 4 on the grounding wire can be further improved.

[0047] In one implementation, such as Figures 1-3 As shown, it also includes a handrail 3, which is connected to the outer wall of the ground cone body 1. During the hammering process, the handrail 3 can be used to maintain the verticality of the ground cone body 1, ensuring that the ground cone body 1 is inserted into the stratum vertically.

[0048] In one implementation, such as Figures 1-3 As shown, the handrail 3 includes a horizontal support arm 32 and an oblique support arm 31 connected to each other. The horizontal support arm 32 is vertically connected to the ground cone body 1, and the oblique support arm 31 is obliquely connected to the ground cone body 1. The horizontal support arm 32, the oblique support arm 31 and the ground cone body 1 are combined to form a right triangle. The right triangle has the stability of a triangle, which can ensure the stability of the handrail 3. When it is necessary to remove the grounding electrode ground cone inserted into the stratum, the handrail 3 can be used as a support point to lift the ground cone body 1 with a pry bar, which further improves the ease of use of the grounding electrode ground cone.

[0049] In one implementation, such as Figures 1-5 As shown, it also includes a top plug 5, which includes a sealing part 51 and a first threaded part 52 connected to each other. The first port of the ground cone body 1 is a threaded port, and the first threaded part 52 can be threadedly connected to the threaded port. Thus, the top plug 5 is installed on the ground cone body 1 by thread. After the installation of the top plug 5 is completed, the sealing part 51 can close the first port. Therefore, when the grounding electrode ground cone is inserted into the stratum, it can prevent soil from entering the first cavity during the hammering process and causing blockage of the first cavity, ensuring that the first cavity has sufficient capacity and can connect to the injection bottle 8 to achieve continuous and stable communication between the injection bottle 8 and the drainage hole 61.

[0050] In one implementation, such as Figure 4 As shown, the top plug 5 also includes an extension 53. One end of the extension 53 is connected to the first threaded portion 52, and the other end of the extension 53 is used to extend to a position close to the second cavity. The extension 53 can occupy the space of the first cavity. During the hammering process, soil may enter the second cavity of the tip 6 through the drainage hole 61 and then enter the first cavity of the ground cone body 1. At this time, the extension 53 can prevent the soil from moving further upward, thereby avoiding blockage of the first cavity. In addition, in the initial stage of inserting the grounding electrode cone into the stratum, the resistance-reducing agent in the main body 1 of the grounding electrode cone enters the stratum relatively slowly (there may also be soil blocking the drainage hole 61), making it difficult to achieve a good resistance-reducing effect in a short time. At this time, after injecting the resistance-reducing agent into the first cavity, a top plug 5 can be installed. The extension 53 connected to the top plug 5 forms a piston structure. By pushing the top plug 5 downward, the extension 53 can provide the movement pressure of the resistance-reducing agent in the first cavity, thereby accelerating the resistance-reducing agent to penetrate the drainage hole 61, so that the resistance-reducing agent can quickly diffuse to the periphery of the grounding electrode cone.

[0051] In one implementation, such as Figure 6 As shown, it also includes an injection interface 7, which is an adapter used to expand the diameter of the first port to the diameter of the bottle opening of the injection bottle 8, so as to facilitate the installation of the injection bottle 8. The injection interface 7 includes a through port and a second threaded portion connected to each other. The second threaded portion is used to be threadedly connected to the threaded port (the first port of the ground cone body 1), and the through port is used to connect to the bottle opening of the injection bottle 8. After the injection bottle 8 is installed, the injection interface 7 can connect the injection bottle 8 and the first cavity, thereby continuously introducing the drag-reducing agent in the injection bottle 8 into the first cavity. It should be noted that if the injection bottle 8 is a deformable and compressible bottle such as a mineral water bottle, the injection pressure of the drag-reducing agent can be provided by compressing the injection bottle 8, thereby achieving a function similar to the aforementioned extension 53.

[0052] Table 1 Technical Parameters and Materials

[0053]

[0054] Table 1 shows the materials and parameters of the main components of the grounding electrode cone disclosed in this invention. Based on the data in Table 1 and related information, this invention can achieve the following technical effects:

[0055] 1. The ground cone body 1 can guide the drag-reducing agent directly to the tip 6 and evenly penetrate into the surrounding soil through the drainage hole 61, ensuring the effective distribution of the drag-reducing agent in the deep soil layer.

[0056] 2. The injection interface 7 can be inserted into the mouth of common mineral water bottles (such as Nongfu Spring, Yibao and other brands), and the drag-reducing agent can be quickly injected without additional tools, which significantly reduces the operation threshold.

[0057] 3. The hammering part 22 of the hammering structure 2 is designed with a trapezoidal hammering surface. This hammering surface is compatible with ordinary hammers, which makes it convenient for construction personnel to drive the grounding electrode cone into the ground by hammering, thus helping the grounding electrode cone to be installed quickly in complex geological conditions.

[0058] 4. Grounding connector 4 supports parallel connection of multiple grounding wires with a current carrying capacity of ≥100A, meeting the requirements of high current grounding and ensuring the stability and reliability of the grounding system.

[0059] 5. The drainage holes 61 are distributed in a ring to effectively prevent salt accumulation and blockage in high-salt and alkaline lands and sand accumulation in desert areas, ensuring the smooth flow of the ground cone body 1 and the long-term stability of the grounding electrode cone.

[0060] 6. The main body of the ground cone 1, the hammering structure 2, the handrail 3, the grounding connection bolt 4, etc. are made of stainless steel 304, which has good corrosion resistance. After testing, the salt spray resistance performance in harsh environments such as high salt and alkali and humidity is ≥1000 hours, which significantly improves the service life. The actual service life is ≥5 years.

[0061] like Figures 1-6 As shown, the present invention provides a grounding method using a grounding electrode cone as described above, including the following:

[0062] S1. Strike the hammer face to drive the grounding electrode cone into the ground to the set depth;

[0063] S2. Inject a drag-reducing agent into the first cavity of the ground cone body 1, and allow the drag-reducing agent to penetrate into the surrounding soil layer through the drainage hole 61.

[0064] S3. Connect the grounding wire to the ground cone body 1.

[0065] This invention is applicable to the following scenarios:

[0066] 1. Power system grounding: grounding of substations and transmission line towers.

[0067] 2. Grounding of communication base stations: rapid grounding of communication facilities in desert and Gobi areas.

[0068] 3. Grounding of industrial equipment: anti-corrosion grounding for equipment in high-salt and alkaline chemical plants and coastal areas.

[0069] 4. Emergency Rescue: Temporary grounding deployment after disasters such as earthquakes and typhoons.

[0070] Through the above technical solutions, this invention effectively solves the technical problems of traditional grounding electrodes in harsh environments, and has the advantages of high efficiency resistance reduction, rapid installation and long service life, with significant engineering application value and economic benefits.

[0071] The following are examples of applications provided by this invention:

[0072] Example 1: Grounding construction in saline-alkali land

[0073] Construction preparation

[0074] 1. Prepare a 550ml mineral water bottle as the injection bottle 8, fill it with the prepared drag-reducing agent (such as a high molecular polymer drag-reducing agent), and embed it into the injection interface 7 connected to the first port of the ground cone body 1. The injection interface 7 is made of nylon rod.

[0075] 2. Check whether the surface of the grounding electrode cone is intact and ensure that the drainage hole 61 is not blocked.

[0076] Installation steps

[0077] 1. Driving the ground cone body 1: Use a regular hammer to strike the hammering surface of the hammering structure 2, driving the ground cone body 1 vertically into the soil until the top of the ground cone body 1 is about 100mm from the ground (total driving depth 800mm), which takes about 3 minutes. During the hammering process, the hammering structure 2 effectively disperses the impact force and prevents the ground cone from tilting.

[0078] 2. Injecting the resistance-reducing agent: Squeeze the injection bottle 8, and the resistance-reducing agent flows into the tip 6 through the first chamber and the second chamber. It then permeates evenly into the surrounding soil through the end drainage hole 61, forming a low-resistance conductive channel.

[0079] 3. Connect the ground wire: Fix the multi-strand ground wire with the ground wire connector 4 made of M12 stainless steel connector to ensure a firm connection.

[0080] Effect detection

[0081] The grounding resistance was measured to be 3.8Ω using a grounding resistance meter, which is more than 60% lower than that of the traditional grounding electrode (9.5Ω), meeting the requirement of ≤4Ω for grounding resistance in saline-alkali land in GB 50169-2016 "Code for Construction and Acceptance of Grounding Devices".

[0082] Example 2: Emergency Repair in the Desert

[0083] Scenario requirements

[0084] A grounding fault occurred on a power transmission line in a desert area, requiring the rapid deployment of grounding electrodes to restore power supply.

[0085] Implementation steps

[0086] 1. Select a grounding electrode cone made of 304 stainless steel. No additional anti-corrosion treatment is required. Simply insert a mineral water bottle containing a resistance reducing agent as the injection bottle 8 into the injection interface 7 of the first port of the grounding cone body 1.

[0087] 2. Hammer the main body of the ground cone to a depth of 600mm in the sand layer (because the desert soil is loose, the actual driving speed is faster than in saline-alkali land, taking about 2 minutes).

[0088] 3. After injecting the resistance-reducing agent, connect the multiple ground wires to complete the grounding system construction.

[0089] Performance testing

[0090] 1. After passing a 500A high-current test and being continuously powered on for 10 minutes, the grounding electrode temperature rise was less than 30K, and the grounding connection bolt 4 showed no loosening or overheating, indicating that its current carrying capacity and connection stability meet the needs of emergency repair.

[0091] 2. After a month of testing in a windy and sandy environment, the drainage hole 61 was not blocked by sand particles, the ground cone showed no obvious displacement, and the grounding resistance remained stable at around 5Ω, proving its reliability in the desert environment.

[0092] The grounding electrode cone and grounding method of the present invention have the following technical effects:

[0093] 1. Increased efficiency in detection:

[0094] The resistance-reducing agent precisely penetrates through the ground cone body 1, reducing the grounding resistance by more than 50% compared to traditional methods. A single injection can quickly achieve the required standard (reducing the resistance in saline-alkali land from 9.5Ω to 3.8Ω), shortening the testing cycle. Furthermore, the top resistance-reducing agent can maintain a low resistance state for a longer period through the injection bottle 8, and can also be reused to replenish the resistance-reducing agent level.

[0095] The standardized interface is compatible with general testing equipment, and the grounding connector 4 supports simultaneous testing of multiple grounding wires, improving data accuracy and testing efficiency.

[0096] 2. Rapid Disaster Relief:

[0097] The hammering surface design of the hammering structure 2 achieves "instant stabilization upon impact," with a penetration time of ≤2 minutes in desert areas and ≤3 minutes in rocky areas, meeting the emergency grounding requirements in disaster scenarios.

[0098] The mineral water bottle, used as the injection bottle 8, can be directly connected to inject the resistance reducing agent, saving the preparation time of traditional tools. Combined with the quick-connect grounding bolt 4, the overall deployment time is reduced to within 10 minutes, significantly improving the emergency response speed.

[0099] 3. Environmental adaptability:

[0100] The wind-resistant and salt-alkali-resistant structural design ensures long-term stable operation in extreme environments, reduces the frequency of repeated testing and maintenance, and provides reliable grounding protection for emergency equipment.

[0101] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
