Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical engineering grounding technology, and specifically relates to an electrical engineering grounding device. Background Technology
[0002] Electrical engineering is one of the core disciplines in modern science and technology. It involves many aspects such as the generation, transmission, distribution and application of electricity. The application of electrical engineering is very wide, covering many fields such as industrial production, transportation, communication, medical care, and smart homes. In order to ensure the normal operation of equipment, stabilize the potential of equipment, reduce electromagnetic interference and static electricity accumulation, and prevent overvoltage from damaging the equipment, electrical engineering requires the use of grounding devices.
[0003] Grounding devices are located underground for extended periods, making them susceptible to electrochemical corrosion and necessitating the replacement of the grounding rods. However, current technology buries the grounding rods directly underground, requiring excavation for replacement, which complicates the process. Therefore, this paper proposes a technical solution to address the issue of the need for excavation and the resulting inconvenience in replacing grounding rods under existing technology. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrical engineering grounding device, which aims to solve the problem that the ground needs to be excavated when replacing the grounding rod, and the convenience of replacement needs to be improved.
[0006] (2) Technical solution
[0007] To address the aforementioned technical problems, this utility model provides an electrical engineering grounding device, comprising a base and a grounding rod. The base has a groove in the middle and a threaded hole in the middle, directly below the groove. A protective tube is threadedly connected to the threaded hole, with a threaded bottom on the protective tube. Two sets of symmetrically distributed limiting components are threadedly mounted on the upper surface of the base. Two sets of insertion holes are provided on the upper side of the grounding rod. Thanks to the combined use of the protective tube and limiting components, the grounding rod is movably fixed, and the grounding rod does not directly contact the soil, reducing the soil's compressive force. This facilitates the removal of the grounding rod during replacement without excavating the ground, thus improving the convenience of replacement.
[0008] Furthermore, the upper surface of the base has multiple sets of evenly distributed circular holes, and the circular holes are slidably fitted with fixing rods, the lower ends of which are pointed.
[0009] Furthermore, the groove is fitted with an insulating ring, and the grounding rod is fitted with the insulating ring.
[0010] Furthermore, a connecting piece is installed on the top of the grounding rod, and the size of the grounding rod is smaller than that of the protective tube.
[0011] Furthermore, the limiting component includes a box body, an ear plate is installed at the middle position of the lower end of the side of the box body, the box body is threaded onto the upper surface of the base through the ear plate, and a limiting groove is formed in the lower part of the box body.
[0012] Furthermore, one end of the box body is recessed, and a connecting rod is slidably connected to the box body. The connecting rod is connected to a pull ring, and a connecting plate is installed at the end of the connecting rod away from the pull ring. A spring is sleeved on the outside of the connecting rod, with one end of the spring installed on the inner side of the box body and the other end of the spring installed on the side of the connecting plate. A vertical plate is installed at the lower middle position of the connecting plate, and a mounting plate is connected to the lower end of the vertical plate. An insert rod is installed on the side of the mounting plate, and an insulating post is installed at the end of the insert rod away from the mounting plate.
[0013] Furthermore, the vertical plate is slidably adapted to the limiting groove, and the insertion rod and insulating column are slidably adapted to the side hole and insertion hole.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the installation of a protective tube, facilitates the separation of the soil from the grounding rod, preventing the soil from exerting force on the grounding rod, thereby making it easier to remove the grounding rod in the next step.
[0017] The limiting component enables the grounding rod to be fixed in place, making it easy to remove. The insulating post prevents current from flowing out of the grounding rod. Pulling the pull ring causes the insertion rod and insulating post to retract into the base. Then, the grounding rod is inserted into the insulating ring. After releasing the pull ring, the insulating post is inserted into the socket under the action of the spring, completing the installation of the grounding rod.
[0018] By using the protective tube and limiting components together, the grounding rod can be fixed in place, and the grounding rod does not come into direct contact with the soil, reducing the compressive force on the soil. This makes it easy to remove the grounding rod when it is replaced, and there is no need to excavate the ground, thus improving the convenience of replacement. Attached Figure Description

[0027] This specific embodiment is an electrical engineering grounding device, and its structural schematic diagram is shown below. Figure 1 , Figure 2 , Figure 3As shown, the device includes a base 1 and a grounding rod 4. A groove 11 and a threaded hole 12 are located in the middle of the base 1, directly below the groove 11. A protective tube 3 is threadedly connected to the threaded hole 12, with threads at the bottom of the protective tube 3. Two sets of symmetrically distributed limiting components 2 are threadedly installed on the upper surface of the base 1. Two sets of insertion holes 9 are located on the upper side of the grounding rod 4. Multiple sets of evenly distributed circular holes 5 are located on the upper surface of the base 1. A fixing rod 10 is slidably fitted to each circular hole 5, with a pointed end at the lower end of the fixing rod 10. An insulating ring 6 is fitted to the groove 11, and the grounding rod 4 is fitted to the insulating ring 6. A connecting piece 8 is installed on the top of the grounding rod 4. The grounding rod 4 is smaller than the protective tube 3. In actual use of this grounding device, a pit is first dug, and... Insert the protective tube 3, then fill it with soil (be careful not to let the soil enter the inside of the protective tube 3), then clean the opening of the protective tube 3, rotate the base 1 so that the threaded hole 12 of the base 1 connects with the protective tube 3, then insert the fixing rod 10 to fix the base 1, then pull the limiting component 2 outward, then insert the grounding rod 4 into the insulating ring 6 (the insulating ring 6 separates the grounding rod 4 from the base 1, making it easier for the current to enter the ground, and the grounding rod 4 does not contact the protective tube 3), then use the limiting component 2 to fix the grounding rod 4, then connect the grounding rod 4 to the electrical equipment through the connecting piece 8 and the wire. The grounding rod 4 directly conducts the current to the ground. When it is necessary to replace the grounding rod 4, release the limiting component 2 to release the limiting of the grounding rod 4, and then take the grounding rod 4 out upward.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the limiting component 2 includes a box body 201. An ear plate 204 is installed at the lower center of the side of the box body 201. The box body 201 is threaded onto the upper surface of the base 1 via the ear plate 204. A limiting groove 211 is formed at the lower part of the box body 201. One end of the box body 201 is recessed. A connecting rod 203 is slidably connected to the box body 201. A pull ring 202 is connected to the connecting rod 203. A connecting plate 206 is installed at the end of the connecting rod 203 away from the pull ring 202. A spring 205 is sleeved on the outside of the connecting rod 203. One end of the spring 205 is installed on the inner side of the box body 201, and the other end is installed on the side of the connecting plate 206. A vertical plate 208 is installed at the lower center of the connecting plate 206. A mounting plate 210 is connected to the lower end of the vertical plate 208. A mounting plate 210 is installed on the side of the mounting plate 210. An insulating post 207 is installed at the end of the insertion rod 209 away from the mounting plate 210. The vertical plate 208 is slidably adapted to the limiting groove 211. The insertion rod 209, the insulating post 207, the side hole 7, and the insertion hole 9 are slidably adapted to each other. Pulling the pull ring 202 moves the connecting rod 203. The movement of the connecting rod 203 moves the connecting plate 206. The movement of the connecting plate 206 compresses the spring 205. The movement of the connecting plate 206 moves the vertical plate 208 along the limiting groove 211. The movement of the vertical plate 208 moves the mounting plate 210 and the insertion rod 209. The movement of the insertion rod 209 moves the insulating post 207 into the base 1. Then, the grounding rod 4 is inserted into the insulating ring 6. Then, the pull ring 202 is released. Under the action of the spring 205, the insulating post 207 is inserted into the insertion hole 9, completing the installation of the grounding rod 4.
[0029] Working principle: When using this grounding device, first dig a pit, put the protective pipe 3 in, and then fill it with soil (note that the soil should not enter the inside of the protective pipe 3). Then clean the opening of the protective pipe 3, rotate the base 1 so that the threaded hole 12 of the base 1 connects with the protective pipe 3, then insert the fixing rod 10 to fix the base 1, then pull the limiting component 2 outward, then insert the grounding rod 4 into the insulating ring 6 (the insulating ring 6 separates the grounding rod 4 from the base 1, making it easy for the current to enter the ground, and the grounding rod 4 does not contact the protective pipe 3), then use the limiting component 2 to fix the grounding rod 4, then connect the grounding rod 4 to the electrical engineering equipment through the connecting piece 8 and the wire. The grounding rod 4 directly conducts the current to the ground. When it is necessary to replace the grounding rod 4, release the limiting component 2 to the grounding rod 4, and then take the grounding rod 4 out upward. The setting of the protective pipe 3 makes it easy to separate the soil from the grounding rod 4, preventing the soil from exerting force on the grounding rod 4, thus making it easy to take out the grounding rod 4 in the next step.
[0030] The specific working method of the limiting component 2 is as follows: pulling the pull ring 202 drives the connecting rod 203 to move, the connecting rod 203 moves the connecting plate 206 to move, the connecting plate 206 moves and compresses the spring 205, the connecting plate 206 moves and drives the vertical plate 208 to move along the limiting groove 211, the vertical plate 208 moves and drives the mounting plate 210 and the insertion rod 209 to move, the insertion rod 209 moves and drives the insulating column 207 to retract into the base 1, then the grounding rod 4 is inserted into the insulating ring 6, and then the pull ring 202 is released, and under the action of the spring 205, the insulating column 207 is driven to insert into the insertion hole 9, completing the installation of the grounding rod 4. Through the setting of the limiting component 2, the grounding rod 4 is movablely fixed, which makes it easy to remove the grounding rod 4, and the insulating column 207 can prevent current from flowing out of the grounding rod 4, ensuring the grounding effect.
