Description

Technical Field

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

[0002] In power engineering, grounding piles are important components to ensure the safe operation of power systems. They are mainly used to connect electrical equipment or systems to the earth to achieve safety protection, equipment protection, and system stability.

[0003] An investigation revealed that a Chinese utility model patent discloses a grounding pile for power engineering (publication number: CN210296649U), comprising a hollow pile tube, a cap connected to the upper end of the pile tube, and a grounding needle disposed inside the pile tube. The lower end of the pile tube is open, and a current-guiding ring is disposed inside the pile tube and contacts the lower end of the grounding needle. The current-guiding ring is slidably connected to the pile tube. Several metal columns perpendicular to the current-guiding ring are connected to the lower end of the current-guiding ring. The cap is connected to the upper end of the pile tube, and the side wall of the cap has an installation hole.

[0004] In the aforementioned patent, an installation plate is set above the pile pipe, and a clamping frame is connected to the installation plate. The clamping frame can extend and retract under the action of the telescopic rod and spring, thereby enhancing the limiting effect of the clamping frame on the grounding pin and accommodating grounding pins of different specifications. However, this setting may not be efficient and stable enough during installation, which may result in poor stability during use and affect the actual use effect.

[0005] Therefore, this utility model provides a power grounding pile for power engineering to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a power grounding stake for power engineering, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the power grounding pile for the power engineering includes a grounding pile body 1, a plug 2 fixedly installed at the bottom of the grounding pile body 1, a control rod 3 slidably installed inside the grounding pile body 1, and a control mechanism set inside the grounding pile body 1 to improve stability.

[0027] The control mechanism includes a lifting rod 4 fixedly installed at the bottom of the control rod 3, a fixed slider 5 fixedly installed on the lifting rod 4, a movable block 6 slidably installed inside the grounding pile body 1, an inclined groove 7 opened inside the movable block 6, an extension plate 8 fixedly installed on the movable block 6, multiple through grooves 9 opened on the extension plate 8, and a sliding groove 10 opened on the grounding pile body 1 for the extension plate 8 to slide. The fixed slider 5 is slidably connected inside the inclined grooves 7 on the two movable blocks 6.

[0028] When using this power grounding pile for power engineering, the plug 2 is aligned with the ground, and the grounding pile body 1 is rotated to insert it into the ground. After the grounding pile body 1 and plug 2 are inserted to a suitable depth, the control rod 3 is pressed down. The movement of the control rod 3 drives the lifting rod 4 to move downward simultaneously. The movement of the lifting rod 4 drives the fixed slider 5 to move downward synchronously. The fixed slider 5 moves inside the inclined groove 7 on the two moving blocks 6, thereby pressing the two moving blocks 6 outward simultaneously. The movement of the two moving blocks 6 drives the extension plate 8 connected to it to move along the sliding groove 10 until the two extension plates 8 completely extend outside the grounding pile body 1. The interior of the multiple through grooves 9 is filled with soil, which makes the power grounding pile for power engineering more stable during installation and improves the stability of the power grounding pile for power engineering in actual use. At the same time, the power grounding pile for power engineering is more difficult to pull back, reducing the problem of the power grounding pile for power engineering being stolen after installation.

[0029] Furthermore, in order to support the power grounding piles used in this power project during their application, such as... Figure 1 , Figure 2 and Figure 5 As shown, an upper connecting ring 11 is fixedly connected to the side surface of the grounding pile body 1, and a support plate 12 is rotatably connected to the side surface of the upper connecting ring 11. Multiple support plates 12 are provided, and the multiple support plates 12 are distributed in a ring array on the upper connecting ring 11.

[0030] A telescopic rod 13 is rotatably connected to the side surface of the upper connecting ring 11. Multiple telescopic rods 13 are provided and are arranged in a ring array on the upper connecting ring 11. A lower connecting ring 14 is fixedly connected to the side surface of the grounding pile body 1.

[0031] A rotating rod 15 is rotatably connected to the side surface of the lower connecting ring 14. Multiple rotating rods 15 are provided and are arranged in a ring array on the lower connecting ring 14. A connecting rod 16 is rotatably connected to the end of the rotating rod 15 away from the lower connecting ring 14.

[0032] The end of the connecting rod 16 away from the rotating rod 15 is rotatably connected to one side of the support plate 12, and the movable end of the telescopic rod 13 is rotatably connected to the end of the rotating rod 15 away from the lower connecting ring 14.

[0033] When using this power grounding pile for power engineering, firstly, multiple support plates 12 are pried open, causing the support plates 12 to rotate counterclockwise around the point where they connect to the upper connecting ring 11. The rotation of the support plates 12 drives the connecting rod 16 and the rotating rod 15 to rotate synchronously. The rotation of the rotating rod 15 causes the telescopic rod 13 to extend, providing support for the entire structure. When not in use, the multiple support plates 12 are manually pried open, causing the support plates 12 to rotate counterclockwise around the point where they connect to the upper connecting ring 11. At the same time, the connecting rod 16 and the rotating rod 15 rotate synchronously. The rotation of the rotating rod 15 causes the telescopic rod 13 to retract until the multiple support plates 12 fit into the interior of the grounding pile body 1. This significantly reduces the space occupied and facilitates storage and transportation.

[0034] Furthermore, in order to, such as Figure 1 , Figure 2 and Figure 5 As shown, each support plate 12 is fixedly connected to an abutment block 17 at the end away from the upper connecting ring 11. A threaded rod 18 is screwed into the inside of the abutment block 17, and a threaded hole adapted to the threaded rod 18 is opened inside the abutment block 17.

[0035] When the power grounding pile for this power project is in use, after the multiple support plates 12 are opened, multiple abutment blocks 17 will contact the ground. Then, by aligning the threaded rods 18 with the threaded holes on the abutment blocks 17, the threaded rods 18 are rotated until they penetrate into the soil. On the one hand, this can further increase the tightness of the connection between the power grounding pile and the ground. On the other hand, when encountering some wind, external forces or other disturbances, the threaded rods 18 that penetrate into the soil can play an anchoring role, preventing the power grounding pile for this power project from shifting, thereby ensuring the stability of the grounding system.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
