Abstract
Description
Technical Field
[0001] This invention relates to the technical field of power engineering, and more particularly to a power grounding pile for power engineering. Background Technology
[0002] In power engineering construction, grounding piles are important devices to ensure the safe operation of electrical equipment and prevent lightning strikes and leakage accidents. Traditional grounding piles are mostly fixed metal piles driven directly into the ground, relying on the friction between the pile and the soil for fixation. However, under adverse geological conditions such as loose, sandy soil or high groundwater levels, these piles are prone to loosening, being pulled out, or having unstable grounding resistance, leading to a decrease in grounding effectiveness and affecting system safety.
[0003] In existing technologies, some expandable grounding piles expand the pile body through mechanical or hydraulic means to enhance the anchoring force. However, they generally suffer from problems such as complex structure, inconvenient installation, uneven expansion, or large expansion resistance. Especially in the initial driving stage, the overall expansion structure is easily subject to large soil resistance, leading to installation difficulties or even damage to the pile body. Summary of the Invention
[0004] The present invention aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this invention is to provide a power grounding pile for power engineering, which uses a rotating fastening bolt to drive guide plates of different heights to press down in sequence, so that the conical pile body can expand step by step from local to overall, effectively reducing the initial expansion resistance and improving the driving efficiency.
[0006] To achieve the above objectives, the present invention proposes a power grounding pile for power engineering, comprising a conical pile body and a stabilizing mechanism; the stabilizing mechanism includes a fastening bolt threaded into the conical pile body; a conical block is fixedly installed at one end of the fastening bolt located within the conical pile body; multiple guide plates are installed on the inner wall of the conical pile body; and an insertion assembly is provided on the conical pile body.
[0007] In addition, the power grounding pile for power engineering proposed in the above application may also have the following additional technical features: Specifically, the lower end of the conical pile is divided into four equal parts at equal angles, and multiple guide plates are respectively installed on the corresponding parts of the conical pile.
[0008] Specifically, the multiple guide plates are all triangular, and the corresponding guide plates located at different parts of the conical pile body are installed at different heights on the inner wall of the conical pile body.
[0009] Specifically, the insertion assembly includes multiple mounting slots formed on the conical pile body; a sliding groove is formed on the conical pile body and in the corresponding mounting slot; a sliding rod is slidably disposed in the multiple sliding grooves; a reinforcing plate is fixedly installed at one end of the multiple sliding rods; and multiple push rods are slidably disposed inside the conical pile body.
[0010] Specifically, multiple push rods are located on one side of the fastening bolt, and multiple push rods are located on one side of the corresponding reinforcing plate.
[0011] Specifically, the top of the plurality of reinforcing plates is sloped, and the sliding rod is installed at a position slightly below the top of the reinforcing plate.
[0012] The power grounding pile for power engineering of the present invention uses a rotating fastening bolt to drive the guide plate to gradually press down, so that the conical pile body can achieve controlled expansion from the inside to the outside. Since the height of the guide plate is different at different positions, the fastening bolt contacts and pushes each guide plate in turn during the downward movement, thereby realizing the gradual expansion of the conical pile body from local to overall, in stages. This time-sharing expansion method not only reduces the initial expansion resistance, making the pile body easier to anchor in the soil layer, but also effectively increases the interlocking area and friction between the pile body and the surrounding soil, significantly enhancing the foundation anchoring force and overall stability.
[0013] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0017] The following description, in conjunction with the accompanying drawings, describes the power grounding pile used in power engineering according to an embodiment of the present invention.
[0018] Figure 1 This is a schematic diagram of the structure of a power grounding pile for power engineering according to an embodiment of the present invention.
[0019] like Figure 1-Figure 3 As shown, the power grounding pile for power engineering in this embodiment of the invention includes a conical pile body 10 and a stabilizing mechanism 20; the stabilizing mechanism 20 includes a fastening bolt 201 threadedly disposed in the conical pile body 10; a conical block 202 is fixedly installed at one end of the fastening bolt 201 located in the conical pile body 10; a plurality of guide plates 203 are installed on the inner wall of the conical pile body 10; and an insertion component 204 is provided on the conical pile body 10.
[0020] In one embodiment of the present invention, such as Figure 1-Figure 3 As shown, the lower end of the conical pile 10 is divided into four equal parts at equal angles, and multiple guide plates 203 are respectively installed on the corresponding parts of the conical pile 10.
[0021] In one embodiment of the present invention, such as Figure 1-Figure 3 As shown, the multiple guide plates 203 are all triangular, and the corresponding guide plates 203 located at different parts of the conical pile body 10 are installed at different heights on the inner wall of the conical pile body 10.
[0022] It should be noted that the triangular guide plate 203 can slowly open the conical pile 10 when the conical block 202 squeezes the guide plate 203, thereby completing the fixation of the conical pile 10.
[0023] Specifically, in actual operation, the relevant personnel first insert the conical pile 10 into the ground. After insertion, the fastening bolt 201 is rotated. Since the fastening bolt 201 is threadedly connected to the conical pile 10, the rotation of the fastening bolt 201 will cause the fastening bolt 201 to move downward. The downward movement of the fastening bolt 201 will cause the fastening bolt 201 to squeeze the guide plate 203, which in turn will cause the conical pile 10 to expand outward. Since the height of the guide plate 203 is different at different positions of the conical pile 10, the conical pile 10 can be expanded sequentially at different positions.
[0024] By rotating the fastening bolts, the guide plates are gradually pressed down, enabling the conical pile to expand controllably from the inside out. Since the guide plates at different positions have different heights, the fastening bolts contact and push each guide plate in turn during the downward movement, thereby achieving the gradual expansion of the conical pile from local to overall, in stages. This time-sharing expansion method not only reduces the initial expansion resistance, making the pile easier to anchor in the soil layer, but also effectively increases the interlocking area and friction between the pile and the surrounding soil, significantly enhancing the foundation anchoring force and overall stability.
[0025] In one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, the insertion component 204 includes a plurality of mounting slots 2041 formed on the conical pile body 10; a sliding slot 2042 is formed on the conical pile body 10 and in the corresponding mounting slot 2041; a sliding rod 2043 is slidably arranged in the plurality of sliding slots 2042; a reinforcing plate 2044 is fixedly installed at one end of the plurality of sliding rods 2043; and a plurality of push rods 2045 are slidably arranged in the conical pile body 10.
[0026] It should be noted that the push rod 2045 is a combination of a straight rod and multiple bent rods, with the straight rod located on one side of the reinforcing plate 2044 and the bent rods located on the top of the reinforcing plate 2044.
[0027] In one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, a plurality of push rods 2045 are located on one side of the fastening bolt 201, and a plurality of push rods 2045 are located on one side of the corresponding reinforcing plate 2044.
[0028] It should be noted that when the end of the fastening bolt 201 moves, it can squeeze the push rod 2045. It is necessary to ensure that the radius of the end of the fastening bolt 201 is greater than the radius of the multiple push rods 2045.
[0029] In one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, the top of the plurality of reinforcing plates 2044 is inclined, and the sliding rod 2043 is installed at the lower part of the top of the reinforcing plate 2044.
[0030] It should be noted that the sliding rod 2043 is installed at the lower top of the reinforcing plate 2044. After the sliding rod 2043 moves to the bottom of the sliding groove 2042, if the reinforcing plate 2044 is pushed, the reinforcing plate 2044 can still rotate along the sliding rod 2043 because the rotation center of the reinforcing plate 2044 is not on one end of the reinforcing plate 2044.
[0031] Specifically, in actual operation, since the reinforcing plates 2044 on the conical pile 10 are all fixedly connected, when the conical pile 10 is inserted into the ground, the reinforcing plates 2044 will increase the insertion force, making it inconvenient to insert the conical pile 10.
[0032] In the initial state, the reinforcing plate 2044 is retracted into the installation groove 2041. After the installation of the conical pile 10 is completed, the fastening bolt 201 moves downward and squeezes the guide plate 203, while also squeezing the push rod 2045. The downward movement of the push rod 2045 will push the reinforcing plate 2044, causing the reinforcing plate 2044 to slide downward. When the reinforcing plate 2044 drives the sliding rod 2043 to the bottom of the sliding groove 2042, if the push rod 2045 continues to push one end of the reinforcing plate 2044, it will cause one end of the reinforcing plate 2044 to rotate downward, thereby causing the reinforcing plate 2044 inserted into the soil to rotate upward. This increases the lateral contact area between the reinforcing plate 2044 and the soil, increasing the stability of the conical pile 10.
[0033] The downward movement of the fastening bolts not only pushes the guide plate to expand the pile body, but also squeezes the push rod, causing the reinforcing plate to slide downwards and move along the sliding groove to the bottom. When the push rod continues to apply force, one end of the reinforcing plate is compressed and rotates downwards, forcing the other end inserted into the soil to flip upwards and unfold, forming a transverse anchoring plate structure. This action significantly increases the contact area and interlocking force between the reinforcing plate and the surrounding soil, effectively improving pull-out resistance and overturning resistance, and enhancing the overall stability of the conical pile.
[0034] In summary, the power grounding pile used in power engineering according to the embodiments of the present invention, by rotating the fastening bolt to drive the guide plate to be pressed down gradually, enables the conical pile body to achieve controllable expansion from the inside to the outside. Since the height of the guide plate at different positions is different, the fastening bolt contacts and pushes each guide plate in turn during the downward movement, thereby realizing the conical pile body to expand from the local to the whole in stages. This time-sharing expansion method not only reduces the initial expansion resistance, making the pile body easier to anchor in the soil layer, but also effectively increases the interlocking area and friction between the pile body and the surrounding soil, significantly enhancing the foundation anchoring force and overall stability.
