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 transmission lines and related equipment are mostly located outdoors and are susceptible to lightning strikes. 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 ground and prevent damage to conductors or transmission equipment from lightning voltage.

[0003] Currently, most existing power grounding stakes rely on nuts and bolts to fix the wires to the grounding stakes. This is not only troublesome to install, but also because the wires are exposed to the outside, it is easy to accidentally come into contact with the wires and cause danger. In addition, the existing grounding stakes are generally not very stable after being driven into the ground by external force, and the whole structure is easy to shift or even be pulled out, which further affects normal use and thus poses a hidden danger to the safe operation of the line.

[0004] Based on this, this utility model designs a power grounding pile for power engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power grounding pile for power engineering.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power grounding pile for power engineering, comprising a grounding pile body, a limiting plate, a terminal block, a guide plate, a connecting bolt, a grounding cone, barbs, and a cone head. The limiting plate is fixedly connected to the outer side of the upper end of the grounding pile body. A terminal block is provided at the center of the upper end of the limiting plate. The terminal block is fixedly connected to the grounding pile body. Four slots are circumferentially formed on the outer side of the grounding pile body. A guide plate is slidably connected to the grounding pile body. Four grounding cones are spirally connected to the guide plate. Multiple barbs are circumferentially formed on the outer side of the lower end of the grounding pile body. A blade is formed on the outer edge of the barb. A cone head is provided at the lower end of the grounding pile body.

[0007] As a preferred embodiment of this utility model, the terminal block has a groove, a wiring tube is provided inside the groove, a wiring hole is provided on the wiring tube, a conductive rod is fixedly connected to the lower end of the wiring tube, the conductive rod is movably connected inside the terminal block, an insulating rod is fixedly connected to the upper end of the wiring tube, a wire clamping screw is spirally connected inside the insulating rod, and a sealing plate is provided at the front end of the groove.

[0008] As a preferred embodiment of this utility model, a screw head is fixedly connected to the top of the insulating rod, the screw head is located at the top of the terminal block, and a sealing cover is attached to the upper end of the screw head.

[0009] As a preferred embodiment of this utility model, the sealing plate is provided with an anti-slip groove, a wire hole is provided below the anti-slip groove, and sliding strips are provided on both sides of the sealing plate, with the sliding strips slidably connected to the terminal block.

[0010] As a preferred embodiment of this utility model, the side of the limiting plate is fixedly connected with four extension plates in a ring, and each of the four extension plates is spirally connected with a connecting bolt.

[0011] As a preferred embodiment of this utility model, the upper end of the guide plate is provided with four screw holes, and the center of the guide plate is provided with four locking blocks, which are slidably connected in the corresponding locking slots. The center of the guide plate is also provided with four through slots.

[0012] As a preferred technical solution of this utility model, the limiting plate can be spirally connected to the screw hole opened on the upper end of the guide plate by four connecting bolts, and the barb can pass through the through groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, this utility model conceals the connection of the wire by using the provided terminal block. Simply pass the wire end through the through hole on the sealing plate and then through the terminal hole on the conduit. The terminal end is pressed and fixed by tightening the wire clamping screw. Then, by rotating the screw head, the insulating rod is rotated, which in turn rotates the conduit, causing the wire end to wrap around the conduit, thus connecting the wire to the grounding stake. This avoids exposing the connection point of the wire and the grounding stake to the outside, preventing accidental contact. The structure is simple and easy to operate, and it can effectively fix the wire to the grounding stake.

[0015] 2. In use, this utility model first fixes the guide plate to the ground with four grounding cones to keep the guide plate horizontal. Then, the grounding pile body is hammered to drive the grounding pile body into the ground. Through the cooperation of the locking block and the locking groove, it can be ensured that the grounding pile body is inserted vertically into the ground without any tilting. After the limiting plate contacts the guide plate, the limiting plate and the guide plate are connected and fixed by the connecting bolts, thus completing the setting of the grounding pile. The four grounding cones and the multiple barbs at the lower end of the grounding pile body make the grounding pile difficult to pull out easily, and have good stability. Attached Figure Description

The terminal block 3 is fixedly connected to the grounding pile body 1. Four slots 101 are circumferentially opened on the outer side of the grounding pile body 1. The guide plate 4 is slidably connected to the grounding pile body 1. Four grounding cones 6 are spirally connected to the guide plate 4. Multiple barbs 7 are circumferentially arranged on the outer side of the lower end of the grounding pile body 1. A blade surface 701 is opened on the outer edge of the barb 7. A cone head 8 is provided at the lower end of the grounding pile body 1.

[0027] A groove 301 is provided on the terminal block 3, and a wiring tube 302 is provided inside the groove 301. A wiring hole is provided on the wiring tube 302. A conductive rod 303 is fixedly connected to the lower end of the wiring tube 302. The conductive rod 303 is movably connected inside the terminal block 3. An insulating rod 304 is fixedly connected to the upper end of the wiring tube 302. A wire clamping screw 305 is spirally connected inside the insulating rod 304. A sealing plate 306 is provided at the front end of the groove 301.

[0028] The top end of the insulating rod 304 is fixedly connected to a screw head 3041, which is located at the top end of the terminal block 3. The upper end of the screw head 3041 is covered by a sealing cover plate 3042.

[0029] The sealing plate 306 is provided with an anti-slip groove 3061, and a wire hole 3062 is provided below the anti-slip groove 3061. Sliding strips 3063 are provided on both sides of the sealing plate 306, and the sliding strips 3063 are slidably connected to the terminal block 3.

[0030] The aforementioned terminal 3 is made of a material with good conductivity and is coated with an insulating coating. The wiring tube 302 and the conductive rod 303 are also made of conductive materials, while the insulating rod 304 and the wire screw 305 are made of insulating materials. This concealed wiring design of the terminal 3 can prevent the connection points of the wires and grounding stakes from being exposed to the outside, thus preventing accidental electric shock accidents.

[0031] Please refer to Figure 1 , Figure 2 and Figure 6 The side of the limiting plate 2 is fixedly connected with four extension plates 201 in a ring, and each of the four extension plates 201 is spirally connected with a connecting bolt 5.

[0032] The upper end of the guide plate 4 has four screw holes 401, and the center of the guide plate 4 has four locking blocks 402. The four locking blocks 402 are slidably connected in the corresponding locking slots 101. The center of the guide plate 4 also has four through slots 403.

[0033] The limiting plate 2 can be spirally connected to the screw hole 401 at the upper end of the guide plate 4 by four connecting bolts 5, and the barb 7 can pass through the through groove 403.

[0034] Through the structural design of the guide plate 4 and the grounding pile body 1, the guide plate 4 can guide and limit the grounding pile body 1 during the process of inserting it into the ground, so that the grounding pile body 1 can be inserted vertically into the ground. At the same time, after the grounding pile body 1 is inserted, the limiting plate 2 and the guide plate 4 are connected by the connecting bolt 5, which can enhance the stability of the grounding pile body 1. With the cooperation of the barb 7, the grounding pile is not easy to be pulled out.

[0035] The working principle and usage process of this utility model are as follows: In specific use, unscrew the four grounding cones 6 on the guide plate 4 upwards, and then unscrew the four connecting bolts 5 on the limiting plate 2 upwards to disengage the guide plate 4 from the limiting plate 2. The guide plate 4 can then be moved downwards until it reaches its lowest point. Next, insert the grounding pile body 1 downwards into the ground so that the guide plate 4 contacts the ground and is adjusted to a horizontal state. Then, screw the grounding cones 6 back into the guide plate 4 to fix it in place. Finally, drive the grounding pile body 1 downwards into the ground by hammering until the limiting plate 2 contacts the guide plate 4. After the plate 2 contacts the guide plate 4, the limiting plate 2 and the guide plate 4 are fixedly connected together by the connecting bolt 5. When connecting the wire, the wire terminal is passed through the wire hole 3062 on the sealing plate 306 and then through the wire hole on the connecting pipe 302. The wire terminal is pressed and fixed by tightening the wire pressing screw 305. Then, by rotating the screw head 3041, the insulating rod 304 is rotated, which in turn drives the connecting pipe 302 to rotate, so that the wire terminal is wrapped around the connecting pipe 302, thereby realizing the connection between the wire and the grounding stake. This can prevent the connection position of the wire and the grounding stake from being exposed to the outside and avoid accidental contact.
