Description

Technical Field

[0001] This utility model relates to the field of grounding post technology, and in particular to a grounding post for power engineering. Background Technology

[0002] Grounding posts are columnar devices made of metal used to connect the grounding conductor of a power system to the earth. They have good conductivity and corrosion resistance, and can safely conduct fault current or static electricity from electrical equipment to the earth. They are the core component of power system grounding protection. In power engineering, they are directly related to equipment safety and stable system operation. If there is no effective grounding, leakage current or static electricity generated during the operation of power equipment can easily lead to electric shock accidents or equipment damage.

[0003] A search revealed that Chinese Publication No. CN218827884U discloses a power grounding post for power engineering, comprising a hollow grounding post body. The outer wall of the grounding post body has four obliquely penetrating openings for inserting anchor rods. The anchor rods are inserted into these openings, and bolts are threaded onto the outer ring of the top of the anchor rods, with the threaded ends of the bolts also threaded onto the inner wall of the grounding post body. This design solves the problems of existing power grounding posts, which are mostly driven directly into the ground to conduct current, but suffer from weak vertical stability after being driven into the soil. Under external forces, the underground power grounding post may tilt and shift, resulting in instability and reduced current conduction efficiency. This design is suitable for widespread promotion and use.

[0004] The patent specification mentions that "the outer ring of the top of the anchor rod is threaded with a bolt." Grounding posts are mostly buried underground or in concealed locations, such as cable trenches. If a hidden detachment occurs, the initial fault may only manifest as an abnormal increase in grounding resistance, without obvious tripping or equipment damage symptoms. Maintenance personnel need to check each grounding grid node one by one, which is time-consuming and labor-intensive, delaying the fault handling opportunity and leading to an expansion of risks. In response to the above problems, a grounding post for power engineering is proposed. Utility Model Content

[0005] This utility model proposes a grounding post for power engineering, which aims to improve the problem that some existing power engineering grounding posts cannot prevent the entire structure from falling off.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A grounding post for power engineering includes a grounding post body, with multiple anti-detachment mechanisms slidably connected to the four outer corners of the grounding post body, and support rods fixedly connected to the four top corners of the grounding post body, with a position adjustment mechanism fixedly connected to the top of the support rods. The anti-fall-off mechanism includes a blocking rod, which is slidably connected to the outside of the grounding post body. The grounding post body has a cavity, and a limit plate is slidably connected inside the cavity. A reset spring is sleeved on the outside of the blocking rod, and a squeezing assembly is slidably connected inside the grounding post body.

[0007] The above solution provides an anti-fall-off mechanism for the grounding post in this power engineering project. The anti-fall-off mechanism is connected to the grounding post body by a blocking rod. In conjunction with the limiting plate and reset spring in the cavity, the squeezing component can push the blocking rod to extend, enhancing the grip of the grounding post on the ground. The position adjustment mechanism at the top of the support rod facilitates adjustment. The overall design ensures that the grounding post is installed securely and prevents it from falling off. It is also convenient to operate and improves the reliability and safety of the grounding in the power engineering project.

[0008] As a further description of the above technical solution: The extrusion assembly includes an extrusion slide bar, the outside of which is slidably connected to the inside of the grounding post body, and the top of the extrusion slide bar is slidably connected to a limit lever.

[0009] The above solution involves a compression assembly where a compression slide bar is slidably connected to the grounding post body. A top-sliding limit lever fixes its position. Pushing the compression slide bar extends the blocking rod to enhance grip, while the limit lever securely locks the slide bar in place to prevent loosening. This design is simple in structure and easy to operate, ensuring effective operation of the anti-fall-off mechanism while precisely controlling the compression force, thus improving the stability and reliability of the grounding post installation.

[0010] As a further description of the above technical solution: A pull plate is fixedly connected to the top of the limiting lever, and the outside of the pull plate is in contact with the outside of the compression slide bar.

[0011] With the above solution: the pull plate at the top of the limiting rod is in contact with the outside of the squeezing slide bar. Pulling the pull plate can easily separate the limiting rod from the squeezing slide bar, releasing the squeezing slide bar from its fixation. After adjustment, the limiting rod can also be quickly reset and locked by the pull plate. No tools are needed during operation, making it more convenient to apply force. The close fit design makes the movement of the limiting rod more stable, ensuring the fixing effect of the squeezing slide bar and improving the convenience of adjustment and use of the grounding post anti-drop mechanism.

[0012] As a further description of the above technical solution: The position adjustment mechanism includes a fixed ring, which is fixedly connected to the outside of the support rod. A sliding lever is slidably connected inside the fixed ring. A second cavity is opened inside the fixed ring, and a limit block is slidably connected inside the second cavity. A tension spring is sleeved on the outside of the sliding lever.

[0013] The above solution involves a fixed ring connecting a support rod in the position adjustment mechanism. A sliding lever slides inside the fixed ring, which, in conjunction with a limiting block and tension spring in the second cavity, allows for position adjustment by pulling the sliding lever to compress the spring. When released, the spring rebounds to lock the lever in place. This design makes adjustment convenient, and the spring provides stable elasticity to ensure a secure lock. It also allows for flexible adjustment of the positions of relevant components of the grounding post, improving the device's adaptability and operational stability.

[0014] As a further description of the above technical solution: The sliding lever is externally slidably connected to the inside of the cavity two, the limiting block is internally fixedly connected to the outside of the sliding lever, and a pull plate two is fixedly connected to the outside of the sliding lever.

[0015] The above solution allows the sliding lever to slide within cavity two, with a limiting block fixed to it to restrict the sliding range. Pull plate two facilitates operation of the sliding lever; pulling pull plate two compresses the tension spring of the sliding lever, easily adjusting its position. Upon release, the spring rebounds, and the limiting block assists the sliding lever in precisely resetting and locking. Operation is effortless and adjustment is precise; the limiting block ensures stable sliding, and pull plate two enhances convenience.

[0016] As a further description of the above technical solution: The outer side of the compression slide bar has multiple slots, and the outer side of the sliding slide bar is locked with the inner side of the slots.

[0017] The above solution involves multiple slots on the outside of the compression slide bar engaging with the sliding rod. The sliding rod can be inserted into different slots to achieve multi-position fixation of the compression slide bar. It also allows for flexible adjustment of the extension length of the compression slide bar, precise control of the extension degree of the blocking rod, and adaptation to different geological fixing requirements. Furthermore, the clamping structure is stable, preventing the compression slide bar from loosening and ensuring the grounding post's anti-fall-off effect.

[0018] As a further description of the above technical solution: The limiting lever is externally slidably connected to the inside of the slot, and the outside of the limiting lever is locked with the outside of the sliding lever.

[0019] The above solution involves a limiting clamping rod sliding to connect to the slot and locking it with the sliding clamping rod, forming a double fixation. The sliding clamping rod first engages with the slot to initially fix the compression rod, and then the limiting clamping rod locks the sliding clamping rod to prevent it from detaching from the slot. This double locking significantly improves the stability of the compression rod, prevents the grounding post from loosening due to vibration or other factors during use, ensures the blocking rod continues to effectively grip the ground, and further enhances the reliability of the grounding post in preventing it from falling off.

[0020] As a further description of the above technical solution: One end of the reset spring is fixedly connected to the inside of the cavity, and the other end of the reset spring is fixedly connected to the outside of the limiting plate.

[0021] With the above solution: the two ends of the reset spring are fixed inside the cavity and outside the limiting plate, respectively. When the squeezing assembly pushes the blocking rod, the limiting plate compresses the spring. After the squeezing assembly is unlocked, the spring rebounds and drives the limiting plate and the blocking rod to reset. The reset spring can not only help the blocking rod to store force when it extends to ensure its stable grip on the ground, but also automatically reset when it does not need to be fixed, which facilitates the disassembly or adjustment of the grounding post and improves the flexibility and reset reliability of the anti-fall-off mechanism.

[0022] This utility model has the following beneficial effects: 1. In this utility model, after the grounding post body is placed underground, pressing and squeezing the sliding rod can push the blocking rod, causing the limiting plate to slide inside the cavity and the blocking rod to extend outward. The extended blocking rod can position the whole, greatly enhancing the fixing stability of the grounding post body, effectively preventing it from falling off. The operation is simple and convenient, requiring no complicated tools, quickly improving the installation firmness of the grounding post, and ensuring the reliable operation of the grounding function.

[0023] 2. In this utility model, pulling the first pull plate disengages the limiting lever from the squeezing slide bar, and then pulling the second pull plate compresses the tension spring of the sliding lever, thereby adjusting the position of the squeezing slide bar. After adjustment, releasing the pull plate causes the spring to rebound, locking the lever into the slot and inserting it into the limiting lever for secondary fixation. This design offers convenient adjustment, double-fixation for stability, ensures precise positioning of the squeezing slide bar, guarantees effective extension of the blocking rod, and improves the stability and operational reliability of the grounding post installation.

[0026] 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.

[0027] Reference Figures 1 to 3 This utility model provides an embodiment of a power engineering grounding post, including a grounding post body 1. The grounding post body 1 is the main channel for current conduction, safely guiding fault current or static electricity from the power system to the ground through the conductivity of its metallic material. Anti-corrosion treatment extends its service life in damp underground environments, ensuring long-term reliable grounding. Multiple anti-detachment mechanisms 2 are slidably connected to the four outer corners of the grounding post body 1. Support rods 3 are fixedly connected to the four top corners of the grounding post body 1. The support rods 3 serve as mounting brackets for position adjustment mechanisms 4, supporting the adjustment mechanisms on the top of the grounding post body 1 to form an operating platform. Simultaneously, the structures distributed at its four corners... The structure ensures that the adjustment mechanism is subjected to balanced forces. The top of the support rod 3 is fixedly connected to the position adjustment mechanism 4, which includes a fixed ring 41. The fixed ring 41 provides installation and sliding space for the sliding rod 42. Its rigid structure ensures the stability of the movement trajectory of the sliding rod 42. At the same time, as a reference component for position adjustment, it achieves the positioning function by cooperating with the sliding rod 42. The fixed ring 41 is fixedly connected to the outside of the support rod 3. The sliding rod 42 is slidably connected inside the fixed ring 41. The sliding rod 42 changes the position of the connecting component by sliding along the fixed ring 41. Its rod-like structure can transmit tension or thrust to achieve precise position adjustment. Specifically, the grounding post body 1 carries current into the earth, has anti-corrosion treatment to extend its service life, an anti-fall-off mechanism 2 to prevent it from falling off, a support rod 3 supports the position adjustment mechanism 4 to ensure balanced force, and in the adjustment mechanism, a fixed ring 41 securely mounts a sliding clamp 42 and sets a reference, while the sliding clamp 42 slides to adjust the position and transmits force to achieve precise positioning, thus ensuring reliable grounding, structural stability and precise adjustment.

[0028] The fixed ring 41 has an internal cavity 43, which provides space for the limiting block 44 and the tension spring 45, protecting these components from external environmental interference. Simultaneously, its inner wall guides the sliding of the limiting block 44, ensuring smooth movement of the sliding lever 42. The limiting block 44 is slidably connected inside the cavity 43, sliding synchronously with the sliding lever 42. Its function is to limit the maximum sliding stroke of the sliding lever 42 (preventing it from completely dislodging from the fixed ring 41) and simultaneously transmit the elastic force of the tension spring 45 to the sliding lever 42, ensuring it remains stably in the set position. The sliding lever 42 is externally sleeved with… A tension spring 45 is provided, which pushes the limiting block 44 and the sliding rod 42 with its elastic force, so that the end of the sliding rod 42 is tightly engaged with the external slot 5 to achieve position locking. The external sliding connection of the sliding rod 42 is slidably connected to the inside of the cavity 43, and the internal connection of the limiting block 44 is fixedly connected to the outside of the sliding rod 42. A pull plate 46 is fixedly connected to the outside of the sliding rod 42. The pull plate 46 provides a convenient force application point for the operator. By pulling the pull plate 46, the sliding rod 42 can be easily driven to overcome the elastic force of the tension spring 45 and slide, thereby achieving position unlocking. The anti-slip design ensures that it is not easy to slip during operation and improves adjustment efficiency. Specifically, cavity 2 43 protects the limiting block 44 and tension spring 45, and guides the limiting block 44 to slide; the limiting block 44 limits the stroke of the sliding rod 42 and transmits elastic force to prevent it from falling out; the tension spring 45 pushes the component to make the sliding rod 42 clamp the slot 5 to achieve stable locking; the pull plate 2 46 can apply force; the anti-slip design helps to unlock, improving the stability of position adjustment and operating efficiency.

[0029] Reference Figures 2 to 3 The anti-fall-off mechanism 2 includes a blocking rod 24. After the grounding post body 1 is inserted into the soil, the blocking rod 24 slides out from the inside. The wedge-shaped structure or barbs at its end can embed into the surrounding soil, increasing the contact area and friction with the soil to form radial support, preventing the grounding post body 1 from moving upward or laterally, thus enhancing overall stability. The blocking rod 24 is externally slidably connected to the outside of the grounding post body 1. The grounding post body 1 has a cavity 21 inside, which provides installation space for the limiting plate 22 and the return spring 23, and at the same time provides a buffer area for the extension and retraction movement of the blocking rod 24, protecting the internal structure. The component is protected from direct impact from soil pressure. The cavity 21 has a sliding connection to a limiting plate 22. The limiting plate 22 slides synchronously with the blocking rod 24. Its function is to limit the maximum extension length of the blocking rod 24 and prevent it from completely detaching from the grounding post body 1. At the same time, it evenly transmits the elastic force of the return spring 23 to the blocking rod 24 to ensure smooth extension and retraction. The outside of the blocking rod 24 is fitted with a return spring 23. The return spring 23 pushes the limiting plate 22 and the blocking rod 24 with elastic force, so that the blocking rod 24 remains in a retracted state when it is not restricted by the squeezing component 25, which facilitates the insertion of the grounding post body 1 into the soil. Specifically, in the anti-detachment mechanism 2, after the blocking rod 24 is inserted into the soil, it slides out, and the anti-grounding post body 1 moves; the cavity 21 protects the limiting plate 22 and the reset spring 23, and also provides a buffer for the extension and retraction of the blocking rod 24. The limiting plate 22 limits the extension length of the blocking rod 24 and transmits the elastic force, and the reset spring 23 causes the blocking rod 24 to retract before it is restricted, so that the grounding post can be inserted. Overall, the installation convenience and anti-detachment stability of the grounding post are improved.

[0030] When the compression assembly 25 is activated, the spring is further compressed, providing reserve elasticity for the extension of the blocking rod 24. The compression assembly 25 is slidably connected inside the grounding post body 1. The compression assembly 25 includes a compression slide rod 251. The compression slide rod 251 slides downward, and its inclined surface compresses the inner end of the blocking rod 24, converting the vertical movement into the horizontal extension and retraction movement of the blocking rod 24, realizing the synchronous extension of multiple blocking rods 24. The structure is simple and has strong linkage. The external part of the compression slide rod 251 is slidably connected inside the grounding post body 1, and the top of the compression slide rod 251 is slidably connected to a limit rod 252 for fixing. The position of the squeezing slide bar 251: When the squeezing slide bar 251 slides down to the preset position, the limiting rod 252 is engaged in the top slot 5 to prevent the squeezing slide bar 251 from rebounding and to ensure that the blocking rod 24 always remains extended. The top of the limiting rod 252 is fixedly connected to the pull plate 253, which provides the operator with a convenient point of force application. By pulling the pull plate 253, the limiting rod 252 can be disengaged from the slot 5 of the squeezing slide bar 251, releasing the lock on the squeezing slide bar 251 and facilitating the retraction of the blocking rod 24. The anti-slip design ensures that it is not easy to slip during operation. The outside of the pull plate 253 is in contact with the outside of the squeezing slide bar 251. Specifically, in the extrusion assembly 25, the extrusion slide bar 251 slides down and pushes the inclined plane to extend the blocking rod 24 simultaneously, with a simple structure and strong linkage; the limit locking rod 252 is locked into the locking groove 5 to fix the slide bar, and the anti-rebound prevents the blocking rod 24 from extending; the pull plate 253 can apply force, the anti-slip design helps to unlock and retract, and the spring reserve elasticity promotes extension, which improves the overall ease of operation and extension stability of the blocking rod 24 and enhances the anti-detachment effect of the grounding post.

[0031] Reference Figures 3 to 4The external of the compression slide bar 251 is provided with multiple slots 5. The slots 5 are the key structure for realizing multiple locking. By cooperating with the sliding rod 42 and the limiting rod 252, the position of the compression slide bar 251 can be fixed to control the extension length of the blocking rod 24, and a double insurance can be formed to prevent the compression slide bar 251 from moving accidentally. The external of the sliding rod 42 is locked with the inside of the slot 5, and the external of the limiting rod 252 is slidably connected to the inside of the slot 5. This sliding connection allows the limiting rod 252 to be accurately embedded in the slot 5, further fixing the position of the compression slide bar 251. The sliding rod 42 restricts the radial movement of the compression slide bar 251, and the limiting rod 252 restricts its axial movement. The double restriction greatly improves the locking reliability. The external of the limiting rod 252 is locked with the external of the sliding rod 42. One end of the return spring 23 is fixedly connected to the inside of the cavity 21, and the other end of the return spring 23 is fixedly connected to the outside of the limiting plate 22. Specifically, the slot 5 cooperates with the sliding rod 42 and the limiting rod 252 to control the extension length of the blocking rod 24 and prevent the squeezing slide rod 251 from moving unexpectedly. The sliding rod 42 limits the radial movement of the slide rod, and the limiting rod 252 limits its axial movement. The dual restriction greatly improves the locking reliability. The reset spring 23 connects the cavity 21 and the limiting plate 22 to help the blocking rod 24 reset, which in turn enhances the locking stability of the squeezing assembly 25 and the anti-detachment effect of the grounding post.

[0032] Working principle: By placing the grounding post body 1 underground, pressing the squeezing slide 251 into the grounding post body 1, the squeezing slide 251 can squeeze the blocking rod 24, which in turn squeezes the limiting plate 22 outside the blocking rod 24, causing the limiting plate 22 to slide inside the cavity 21, which in turn allows the blocking rod 24 to extend outward, thus enabling the blocking rod 24 to play a positioning role for the whole, making the grounding post body 1 more stable and preventing the grounding post body 1 from falling off. When adjusting the position of the extrusion slide bar 251, pulling the first pull plate 253 separates it from the interior of the extrusion slide bar 251 via the limiting rod 252. This releases the limiting rod 252 from the fixed state of the sliding rod 42. At this moment, pulling the second pull plate 46 causes it to slide the limiting block 44 inside the second cavity 43 via the sliding rod 42. This allows the tension spring 4 outside the sliding rod 42 in the second cavity 43 to move. 5. Pressing is performed, which allows the pressing slide bar 251 to move. When the position is adjusted, the tension spring 45 is rebounded by releasing the second pull plate 46, which allows the sliding latch 42 to lock into the slot 5 on the outside of the pressing slide bar 251, thereby locking the pressing slide bar 251. At this time, by lifting the first pull plate 253, the limiting latch 252 is locked into the outside of the sliding latch 42, thereby fixing the pressing slide bar 251.
