Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a power grounding pile for power engineering. Background Technology

[0002] Power grounding stakes are an important piece of equipment in power systems, used to ensure the normal operation of the system and personal safety. Their main function is to dissipate the current in the power system into the ground through ground resistance, ensuring personal safety within the system. When a short circuit or fault occurs in the system, the grounding stake can quickly conduct the current into the ground, preventing large-scale electric shock accidents. At the same time, grounding stakes also help stabilize the voltage and frequency of the power system, reduce stray electromagnetic radiation on power lines, and improve the system's efficiency and stability.

[0003] In the traditional installation process of grounding piles, a hammer is usually used to drive the grounding pile into the ground. However, during the hammering process, the grounding pile is prone to deformation, bending, or tilting at the insertion angle, resulting in the grounding pile not reaching the specified depth and thus affecting the effectiveness of the grounding pile. In order to solve the above problems, the inventor proposes a power grounding pile for power engineering. Utility Model Content

[0004] To address the problem that using a hammer to install grounding piles can easily cause deformation, bending, or tilting of the grounding pile, resulting in the grounding pile not reaching the specified depth and thus affecting its effectiveness, this utility model aims to provide a power grounding pile for power engineering.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a power grounding pile for power engineering, including a cover plate and an auxiliary frame. A grounding pipe is fixedly installed on the lower surface of the cover plate, and a threaded cone is fixedly installed at the bottom end of the grounding pipe. A fixing plate is rotatably installed on the lower surface of the cover plate, and the grounding pipe is inserted through the fixing plate. Four threaded rods distributed in a ring are rotatably installed on the outer ring of the fixing plate. A drive gear is fixedly installed at the top end of each of the four threaded rods. A toothed ring is fixedly installed on the lower surface of the cover plate, and the toothed ring meshes with the drive gear.

[0006] Preferably, the cover plate has a storage groove, and a handle is hinged in the storage groove. The length of the handle is less than the length of the storage groove. The bottom ends of the four threaded rods are tapered. The grounding pipe is a hollow galvanized pipe. A terminal block is fixedly installed in the top of the grounding pipe. A grounding wire is installed on the terminal block and passes through the cover plate.

[0007] Preferably, the auxiliary frame has sliding grooves on both sides, and sliding plates are slidably installed in both sliding grooves. The bottom ends of both sides of the auxiliary frame are fixedly installed with pedals. One end of the upper surface of each of the two sliding plates is fixedly installed with a positioning block. The lower surface of the fixed plate has two symmetrically distributed positioning holes, and the positioning blocks can be inserted into the corresponding positioning holes.

[0008] Preferably, a fixing rod is fixedly installed in each of the two slides, and the fixing rod is inserted through the corresponding sliding plate. A spring is sleeved on each of the two fixing rods, and the top of the spring contacts the lower surface of the corresponding sliding plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, the cover plate drives the grounding pipe and the threaded cone to rotate. The grounding pipe gradually penetrates into the ground through the rotation of the threaded cone. At the same time, the cover plate drives the toothed ring to rotate, the toothed ring drives the drive gear to rotate, the drive gear drives the threaded rod to rotate, and the threaded rod rotates to gradually insert into the ground until the grounding pipe is completely inserted into the ground, thereby completing the installation of the grounding stake. This replaces the traditional method of hammering the grounding stake to install it, preventing the grounding pipe from deforming and bending during the hammering process, which would affect the use effect of the grounding stake.

[0011] 2. In this utility model, by inserting the four threaded rods and the grounding pipe into the ground simultaneously and using an auxiliary frame, it is possible to prevent the insertion angle of the grounding pipe from tilting. The threaded rods can also be used to fix the grounding pipe, which can effectively prevent the grounding pipe from loosening or shifting later. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-6As shown, this utility model provides a power grounding stake for power engineering, including a cover plate 1 and an auxiliary frame 7. A grounding pipe 2 is fixedly installed on the lower surface of the cover plate 1, and a threaded cone 3 is fixedly installed at the bottom end of the grounding pipe 2. A fixing plate 10 is rotatably installed on the lower surface of the cover plate 1, and the grounding pipe 2 is inserted through the fixing plate 10. Four threaded rods 4 are rotatably installed in a ring on the outer ring of the fixing plate 10, and a drive gear 18 is fixedly installed at the top end of each of the four threaded rods 4. A toothed ring 9 is fixedly installed on the lower surface of the cover plate 1, and the toothed ring 9 meshes with the drive gear 18. First, a suitable installation location is selected. The grounding stake should be installed close to the main power source, and cross-installation or locations that are too far away should be avoided as much as possible. Then, the grounding pipe 2 is vertically inserted into the ground through the threaded cone 3 at the bottom end, and at the same time, the bottom end of the threaded rod 4 is inserted into the ground, thereby grounding the fixing plate 1. After setting a limit, the cover plate 1 is rotated, which drives the grounding pipe 2 and the threaded cone 3 to rotate. The grounding pipe 2 gradually penetrates deeper into the ground through the rotation of the threaded cone 3. At the same time, the cover plate 1 drives the toothed ring 9 to rotate, which drives the drive gear 18 to rotate. The drive gear 18 drives the threaded rod 4 to rotate, and the threaded rod 4 rotates and gradually inserts into the ground until the grounding pipe 2 is completely inserted into the ground, thus completing the installation of the grounding stake. This replaces the traditional method of hammering the grounding stake, preventing the grounding pipe 2 from deforming and bending during the hammering process, which would affect the use of the grounding stake. By inserting the four threaded rods 4 into the ground synchronously with the grounding pipe 2 and using the auxiliary frame 7, the insertion angle of the grounding pipe 2 can be prevented from tilting when it is inserted. The threaded rods 4 can also fix the grounding pipe 2, which can effectively prevent the grounding pipe 2 from loosening and shifting later.

[0022] The cover plate 1 has a storage slot 13, and a handle 5 is hinged in the storage slot 13, and the length of the handle 5 is less than the length of the storage slot 13.

[0023] By adopting the above technical solution, the handle 5 drives the cover plate 1 to rotate. When not in use, the handle 5 can be stored in the storage groove 13. The length of the handle 5 is less than the length of the storage groove 13, making it easy to pry out the handle 5.

[0024] The bottom ends of all four threaded rods 4 are tapered.

[0025] By adopting the above technical solution, the tapered design facilitates the insertion of the threaded rod 4.

[0026] The grounding pipe 2 is a hollow galvanized pipe. A terminal block 11 is fixedly installed inside the top of the grounding pipe 2. A grounding wire 6 is installed on the terminal block 11 and passes through the cover plate 1.

[0027] By adopting the above technical solution, the grounding pipe 2 is connected to the power equipment by the grounding wire 6. When a short circuit or fault occurs in the system, the grounding pipe 2 can quickly conduct the current into the ground through the grounding wire 6, thus avoiding a large-scale electric shock accident.

[0028] The auxiliary frame 7 has sliding grooves on both sides, and sliding plates 16 are slidably installed in both grooves. The bottom of both sides of the auxiliary frame 7 is fixedly installed with pedals 8.

[0029] By adopting the above technical solution, the auxiliary frame 7 is fixed by stepping on the pedal 8 with both feet, and the sliding plate 16 can slide up and down in the groove of the auxiliary frame 7.

[0030] A positioning block 17 is fixedly installed on one end of the upper surface of each of the two sliding plates 16. Two symmetrically distributed positioning holes 12 are opened on the lower surface of the fixed plate 10, and the positioning block 17 can be inserted into the corresponding positioning hole 12.

[0031] By adopting the above technical solution, the positioning block 17 on the sliding plate 16 is inserted into the corresponding positioning hole 12 on the fixed plate 10 to position and limit the fixed plate 10. This can prevent the fixed plate 10 from rotating with the cover plate 1 in the early stage, and can also prevent the insertion angle from tilting when the grounding pipe 2 is inserted.

[0032] A fixing rod 14 is fixedly installed in each of the two slides, and the fixing rod 14 is inserted through the corresponding sliding plate 16.

[0033] By adopting the above technical solution, the sliding plate 16 can slide up and down along the fixed rod 14 in the sliding groove.

[0034] Springs 15 are fitted on both fixed rods 14, and the top of the springs 15 contacts the lower surface of the corresponding sliding plate 16.

[0035] By adopting the above technical solution, the rebound force of the spring 15 can be used to ensure that the positioning block 17 on the sliding plate 16 is always inserted into the corresponding positioning hole 12 on the fixed plate 10.

[0036] Working Principle: When using this novel design, first select a suitable installation location. The grounding stake should be installed close to the main power supply, avoiding cross-installation or locations that are too far away. Next, insert the grounding pipe 2 vertically into the ground through the threaded cone 3 at its bottom end. Simultaneously, the bottom end of the threaded rod 4 is also inserted into the ground. Then, step on the pedal 8 with both feet to fix the auxiliary frame 7. Next, insert the positioning block 17 on the sliding plate 16 into the corresponding positioning hole 12 on the fixed plate 10 to position and limit the fixed plate 10. Then, use the handle 5 to rotate the cover plate 1. The cover plate 1 drives the grounding pipe 2 and the threaded cone 3 to rotate. The grounding pipe 2 gradually penetrates deeper into the ground through the rotation of the threaded cone 3. The cover plate 1 drives the gear ring 9 to rotate, the gear ring 9 drives the drive gear 18 to rotate, the drive gear 18 drives the threaded rod 4 to rotate, and the threaded rod 4 rotates and gradually inserts into the ground until the grounding pipe 2 is completely inserted into the ground, thus completing the installation of the grounding stake. This replaces the traditional method of hammering the grounding stake, preventing the grounding pipe 2 from deforming and bending during the hammering process, which would affect the use of the grounding stake. By inserting the four threaded rods 4 into the ground synchronously with the grounding pipe 2 and using the auxiliary frame 7, the angle of insertion of the grounding pipe 2 can be prevented from tilting. The threaded rods 4 can also be used to fix the grounding pipe 2, which can effectively prevent the grounding pipe 2 from loosening and shifting later.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
