Description

Technical Field

[0001] This application relates to the technical field of power grounding piles, and in particular to a power grounding pile for power engineering. Background Technology

[0002] Grounding refers to the connection of the neutral point of a power system and electrical installation, the exposed conductive parts of electrical equipment, and the external conductive parts of the equipment to the earth via a conductor. It can be divided into working grounding, lightning protection grounding, and protective grounding. Grounding piles refer to the ground piles, support piles, and building piles of buildings that can serve as grounding piles. Power transmission lines and related equipment are mostly located outdoors and are easily struck by lightning. Line tripping caused by lightning strikes occurs frequently. In order to protect against lightning strikes, grounding devices need to be installed on transmission lines to conduct the current generated by lightning strikes to the earth and avoid damage to conductors or transmission equipment from lightning voltage. Because reliable grounding is required, grounding devices usually use metal grounding piles.

[0003] A search revealed Chinese Patent Publication No. CN215896745U, which discloses a power grounding stake for power engineering. The grounding stake body has a vertically oriented cavity at its upper part, into which a hydraulic telescopic rod is installed. A vertical connecting channel is located at the lower part of the cavity. Two rows of cavities are symmetrically arranged on opposite sides of the connecting channel, with at least two cavities in each row. Each cavity communicates with the connecting channel, and a fixed cone is installed in each cavity. One end of the fixed cone passes through the outer peripheral wall of the grounding stake body. Two opposing fixed cones are connected by a pulling assembly, and adjacent pulling assemblies are connected by a fixed rope. The top pulling assembly is connected to the hydraulic telescopic rod via a connecting rope. This invention utilizes the force transmission of the pulling rope to achieve lateral pull-out of the fixed cone, moving it into the grounding stake. This facilitates the disassembly of the grounding stake, promotes recycling, reduces costs, and is more environmentally friendly.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The above-mentioned solution can achieve the lateral pull-out of the fixed cone by the force transmission of the pull rope, moving the fixed cone into the grounding stake, thereby facilitating the disassembly of the grounding stake, making it easier to recycle, reducing costs, and being more environmentally friendly. However, this device cannot independently insert the fixed cone into the ground, and the pull rope is prone to breakage during long-term use, affecting subsequent use. Therefore, a new method is needed to solve this problem. Utility Model Content

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model comprises components such as a screw, a first connector, a connecting block, a pile body, a connecting rod, an insert plate, and a buffer groove. A tool is used to connect the screw to the first connector, which is then rotated to rotate the screw. The rotation of the screw causes the connecting block to slide vertically along the pile body. During this process, the insert plate contacts the pile body and slowly opens, sliding along the groove on the side of the pile body until it is horizontally inserted into the ground. The buffer groove prevents the insert plate from squeezing against the pile body, thus enhancing the stability of the grounding pile through the connection between the insert plate and the ground.

Then, a tool is used to connect the second connector, which facilitates the rotation of the threaded rod. The rotation of the threaded rod will move vertically along the corresponding fixed column. When the threaded rod is inserted into the ground, it can enhance the connection between the grounding pile and the ground, thereby achieving the effect of increasing the friction between the grounding pile and the ground through the setting of the threaded rod.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] This application discloses a power grounding stake for power engineering. For example... Figure 2 As shown, the pile includes a pile body 1, with a screw 3 rotatably connected to the inner wall of the pile body 1. The pile body 1 has four sliding grooves 8 inside, and each sliding groove 8 has a fixed groove 9 on its inner wall. Each sliding groove 8 has a baffle 12 slidably connected to its inner wall. The screw 3 can rotate inside the pile body 1. Each sliding groove 8 is set above the corresponding fixed groove 9, and the baffle 12 can slide vertically along the corresponding sliding groove 8.

[0023] Please see Figure 2Each fixed rod 10 has a spring 11 fitted on its outer surface. The top end of each spring 11 is fixedly connected to the corresponding sliding groove 8, and the other end is fixedly connected to the corresponding baffle 12. The outer surface of each fixed rod 10 is slidably connected to the corresponding fixed groove 9. The spring 11 is compressed when the baffle 12 pushes the corresponding fixed rod 10 to slide vertically upward along the corresponding fixed groove 9. When there is no external force, the spring 11 will push the corresponding baffle 12 to reset under its rebound force. The baffle 12 can seal the pile body 1 and prevent soil from the ground from entering the pile body 1.

[0024] Please see Figure 4 The pile body 1 has several installation slots 16 inside. Each installation slot 16 has a grounding rod 17 fixedly installed on its inner wall. Each grounding rod 17 has an installation head 18 fixedly connected to its top. By installing the grounding rod 17 in the corresponding installation slot 16 and then connecting the grounding wire to the installation head 18, lightning can be guided through the grounding rod 17.

[0025] Please see Figure 1 , Figure 2 , Figure 4 Several fixed posts 13 are fixedly connected to the upper surface of the pile body 1. Each fixed post 13 has a threaded rod 14 threadedly connected to its inner wall. Each threaded rod 14 has a second connector 15 fixedly connected to its top end. By inserting the threaded rod 14 into the corresponding fixed post 13 and then connecting the second connector 15 with a tool, the fixed posts 13 are evenly arranged on the upper surface of the pile body 1. When the second connector 15 is rotated, the second connector 15 will drive the corresponding threaded rod 14 to rotate. At this time, the threaded rod 14 will be inserted into the ground through the action of the fixed post 13, thereby increasing the connection between the grounding pile and the ground.

[0026] Please see Figure 1 , Figure 2 , Figure 4 The top of the screw 3 is fixedly connected to a first connector 4. The outer surface of the screw 3 is threadedly connected to a connecting block 5. The outer surface of the connecting block 5 is slidably connected to the pile body 1. The inner wall of the connecting block 5 is fixedly connected to four connecting rods 6. The first connector 4 is connected by using a tool. Then, the first connector 4 is rotated. The first connector 4 will drive the screw 3 to rotate. The rotation of the screw 3 will drive the connecting block 5 to slide vertically along the pile body 1.

[0027] Please see Figure 2 , Figure 3Each connecting rod 6 has a rotatable insert plate 7 on its outer surface. The outer surface of each insert plate 7 is inserted into the pile body 1. The outer surface of the pile body 1 has four buffer grooves 2. The insert plate 7 can rotate around the corresponding connecting rod 6. When the insert plate 7 extends out of the pile body 1, its bottom surface is beveled. The vertical movement of the connecting block 5 will drive the insert plate 7 to move vertically. When the insert plate 7 is retracted into the pile body 1, the insert plate 7 will pass through the buffer groove 2 to prevent the insert plate 7 from being damaged by force during the tilting process. When the insert plate 7 is completely inserted into the pile body 1, the insert plate 7 will be in a tilted state under the action of gravity, and the inclined surface will face the outside of the pile body 1. When the connecting block 5 moves vertically downward, the insert plate 7 will slide along the pile body 1 and gradually tend to be horizontal.

[0028] Please see Figure 2 , Figure 4 Each baffle 12 has its outer surface slidably connected to the corresponding insert plate 7. Each baffle 12 has its upper surface fixedly connected to a fixed insert rod 10. Each fixed insert rod 10 can slide vertically along the corresponding fixed groove 9. The baffle 12 has an oblique angle on the side close to the central axis of the pile body 1. The connection between the baffle 12 and the fixed insert rod 10 allows the two to move synchronously. When the insert plate 7 slides horizontally along the pile body 1, the insert plate 7 will squeeze the baffle 12. Then, through the decomposition of force, the baffle 12 will move vertically upward along the sliding groove 8. When the insert plate 7 is retracted, the baffle 12 will close the pile body 1.

[0029] The implementation principle of a power grounding pile for power engineering in this embodiment is as follows: First, the grounding rod 17 is installed in the corresponding mounting groove 16. Then, the grounding wire is connected to the mounting head 18. At this time, lightning can be guided through the grounding rod 17. Then, a tool is used to connect the second connector 15. The second connector 15 will drive the corresponding threaded rod 14 to rotate. At this time, the threaded rod 14 will be inserted into the ground through the action of the fixing post 13. Then, a tool is used to connect the first connector 4. By rotating the first connector 4, the first connector 4 will drive the screw 3 to rotate. The rotation of the screw 3 will drive the connecting block 5 to slide vertically along the pile body 1. During this process, the vertical downward movement of the connecting block 5 pushes the insert plate 7 to rotate around the corresponding connecting rod 6. During this process, the insert plate 7 pushes and squeezes the corresponding baffle 12, and through the decomposition of force, the baffle 12 drives the corresponding fixed insert rod 10 to move vertically and squeezes the spring 11 to compress it. When the first connecting head 4 is rotated in the opposite direction, the connecting block 5 drives the insert plate 7 to move vertically upward. During this process, the insert plate 7 will tilt, and the buffer groove 2 will prevent the insert plate 7 from being squeezed and broken until the insert plate 7 is completely inserted into the pile body 1. At this time, the spring 11 will push the corresponding baffle 12 to seal the pile body 1 under the action of its rebound force to prevent soil from entering.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
