Description

Technical Field

[0001] This utility model belongs to the field of grounding rod technology, specifically relating to a novel quick-disassembly grounding rod. Background Technology

[0002] Currently, with the rapid development of economic construction, the scale of the power system is expanding in tandem, and the scope and workload of operating and maintaining the power system are becoming increasingly heavy. In actual construction and maintenance, especially for high-voltage cables, it is first necessary to verify whether the cable is energized. If the cable is energized, the residual electricity on the cable is conducted into the ground through a grounding rod to achieve safe construction conditions.

[0003] In existing technologies, grounding rods typically consist of an insulating rod and a metal clamp fixed to one end of the insulating rod, with each part corresponding to the other. However, in actual maintenance, it is often necessary to carry multiple insulating rods. In areas with complex terrain and poor accessibility, they can only be carried by manpower. Walking under heavy loads not only consumes the physical strength of the staff and increases their labor intensity, but also reduces the speed of movement, resulting in low maintenance efficiency. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a new type of quick-disassembly grounding rod to solve the technical problems of high load on workers and low maintenance efficiency caused by the need to carry multiple insulating rods in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel quick-release grounding rod includes an insulating rod and a clamp at the top of the insulating rod. The clamp is equipped with a grounding wire. The clamp and the insulating rod are detachably connected by a transition cylinder. The cross-sectional dimensions of the transition cylinder gradually increase away from the clamp. A cavity is formed inside the transition cylinder that runs through the entire transition cylinder along its length. The cavity includes an upper fixed space, a middle limiting space, and a bottom insertion space that are sequentially connected away from the clamp. A penetrating insertion groove is formed on the side wall of the transition cylinder along the extension direction of the transition cylinder. The insertion groove starts from the bottom opening of the bottom insertion space and extends to the middle position of the middle limiting space. A penetrating limiting groove connected to the top of the insertion groove is formed.

[0007] Furthermore, the upper fixed space and the middle limiting space are cylindrical in shape, and the inner diameter of the upper fixed space is larger than the inner diameter of the middle limiting space. The cross-sectional radius of the bottom insertion space is larger than the cross-sectional radius of the middle limiting space, and the bottom insertion space gradually increases non-linearly along the direction away from the middle limiting space, thus forming a bottom flare.

[0008] Furthermore, the limiting groove is integrally in an "L" shape, which includes a limiting horizontal groove extending along the horizontal circumferential direction and a limiting vertical groove communicating with the limiting horizontal groove. The limiting vertical groove is located at one end of the limiting horizontal groove away from the insertion groove and is below the limiting horizontal groove, and the limiting vertical groove extends along the length direction of the transition cylinder;

[0009] Furthermore, a fixing pin hole extending along the horizontal direction and penetrating the entire transition cylinder is provided at the top of the transition cylinder, and the axis of the fixing pin hole is vertically intersecting with the axis of the upper fixing space;

[0010] Furthermore, the wire clamp includes a frame body with an overall "U" - shaped structure. The top cross - bar of the frame body is concave to form a hook - like shape to fit the circular cable. A lifting screw rod is vertically penetrated through the middle position of the bottom cross - bar of the frame body and is threadedly connected thereto. The bottom of the lifting screw rod forms an insertion section adapted to the upper fixing space;

[0011] Furthermore, sliding grooves are oppositely provided on both sides of the frame body. Guide rails are formed inside the sliding grooves and are slidably connected with a top plate. The top plate is located above the lifting screw rod and the bottom surface of the top plate always contacts the top surface of the lifting screw rod;

[0012] Furthermore, an insertion head coaxial with the insulating rod is formed at the top of the insulating rod. The diameter of the insertion head is the same as the inner diameter of the middle limiting space. A horizontally arranged insertion support rod is provided on the side surface of the free end of the insertion head. The axis of the insertion support rod intersects and is perpendicular to the axis of the insertion head. The widths of the insertion groove and the limiting groove are the same as the diameter of the insertion support rod.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Compared with the prior art, by arranging a transition cylinder between the wire head and the insulating rod, one insulating rod can operate multiple wire clamps. That is, during the maintenance process, there is no need to carry multiple insulating rods, which fundamentally reduces the load of the staff, reduces their labor intensity, and thus effectively improves the traveling speed while ensuring the maintenance efficiency; and the overall structure of the transition cylinder is simple, the installation is convenient, the volume is small and it is easy to carry, which is conducive to large - area promotion and application. <​​​​​​​​​​​​​​​​

[0022] Example 1, specifically as follows Figures 1-4 As shown.

[0023] A novel quick-release grounding rod includes an insulating rod 2 and a clamp 1 located at the top of the insulating rod 2. The clamp 1 is provided with a grounding wire (not shown in the figure), and the two are detachably connected by the grounding clamp. The clamp 1 and the insulating rod 2 are detachably connected by a transition cylinder 3.

[0024] like Figure 1 As shown, the transition cylinder 3 has a circular cross-section with its dimensions gradually increasing away from the clamp 1. A cavity extending through the entire transition cylinder 3 along its length is formed inside the transition cylinder 3, with the cavity's axis coinciding with the axis of the transition cylinder 3. The cavity includes an upper fixing space 301, a middle limiting space 303, and a bottom insertion space 304, which are sequentially connected along the direction away from the clamp 1. It is worth noting that the upper fixing space 301 and the middle limiting space 303 are cylindrical in shape, with the inner diameter of the upper fixing space 301 being larger than that of the middle limiting space 303. The cross-sectional radius of the bottom insertion space 304 is larger than that of the middle limiting space 303, and the bottom insertion space 304 gradually increases in size non-linearly along the direction away from the middle limiting space 303, thus forming a flared bottom. Therefore, the bottom insertion space 304 appears as a "trumpet" shape, narrower at the top and wider at the bottom. In addition, in this embodiment, the heights of the middle limiting space 303, the bottom insertion space 304, and the upper fixing space 301 gradually decrease.

[0025] A fixing pin hole 302 extending horizontally and penetrating the entire transition cylinder 3 is provided on the side wall of the upper fixed space 301 at the top of the transition cylinder 3. The axis of the fixing pin hole 302 intersects perpendicularly with the axis of the upper fixed space 301. Figure 2 , Figure 3As shown, a through-type insertion slot 305 is provided on the side wall of the transition cylinder 3 along the extension direction of the transition cylinder 3. The insertion slot 305 starts from the bottom opening of the bottom insertion space 304 and extends to the middle position of the middle limiting space 303. The through-type insertion slot 305 is specifically that the depth of the insertion slot 305 is greater than the wall thickness of the transition cylinder 3, that is, the cavity is connected to the external space of the transition cylinder 3 through the insertion slot 305.

[0026] A through-type limiting slot 306 connected to the insertion slot 305 is provided at the top end of the insertion slot 305. That is, the depth of the limiting slot 306 is greater than the wall thickness of the transition cylinder 3. The limiting slot 306 is integrally in an "L" shape and includes a limiting horizontal slot 307 extending along the horizontal circumferential direction and a limiting vertical slot 308 connected to the limiting horizontal slot 307. The limiting vertical slot 308 is located at one end of the limiting horizontal slot 307 away from the insertion slot 305 and below the limiting horizontal slot 307. The limiting vertical slot 308 extends along the length direction of the transition cylinder 3.

[0027] The bottom of the wire clamp 1 is inserted into the upper fixing space 301 and a detachable connection is achieved between the wire clamp 1 and the transition cylinder 3. Specifically, the wire clamp 1 includes a frame body 101. In this embodiment, the frame body 101 is integrally in a "U" shape structure. The top cross bar of the frame body 101 is recessed to form a hook shape to fit the circular cable. A lifting screw rod 102 is vertically penetrated through the middle position of the bottom cross bar of the frame body 101 and the two are threadedly connected. A plug-in section adapted to the upper fixing space 301 is formed at the bottom of the lifting screw rod 102. A through pin hole is provided on the plug-in section. The plug-in section is inserted into the upper fixing space 301 from the top opening of the transition cylinder 3 and the through pin hole is aligned with the fixing pin hole, and then a pin is inserted to fix the lifting screw rod 102, so as to achieve the detachable connection between the wire clamp 1 and the transition cylinder 3.

[0028] Sliding grooves are oppositely provided on both sides of the frame body 101. Guide rails are formed inside the sliding grooves and are slidably connected with a top plate 103. That is, the top plate 103 can only displace in the vertical direction. The top plate 103 is located above the lifting screw rod 102 and the bottom surface of the top plate 103 always contacts the top surface of the lifting screw rod 102. In addition, the top plate 103 is recessed on both sides of the frame body 101 to fit the circular cable. A ground wire (not shown in the figure) can also be provided on the wire clamp 1 for leading the remaining electricity in the cable into the ground.

[0029] As Figure 4As shown, a cylindrical connector 201 coaxial with the insulating rod 2 is formed at the top of the insulating rod 2. The connection between the connector 201 and the insulating rod 2 is chamfered. The diameter of the connector 201 is the same as the inner diameter of the central limiting space 303. A horizontally oriented plug-in support rod 202 is welded to the side of the free end of the connector 201. The axis of the plug-in support rod 202 intersects and is perpendicular to the axis of the connector 201. Furthermore, it is worth emphasizing that in this embodiment, the width of the plug-in groove 305 and the limiting groove 306 is the same as the diameter of the plug-in support rod 202.

[0030] In use, firstly, insert the insertion section of the lifting threaded rod 102 into the upper fixed space 301 through the top opening of the transition cylinder 3 and align the through pin hole with the fixed pin hole. Then, insert the pin to fix the lifting threaded rod 102, thus achieving a fixed connection between the clamp 1 and the transition cylinder 3. Secondly, rotate the insulating rod 2 so that the insertion support rod 202 is aligned with the insertion groove 305. Push the insulating rod 2 into the transition cylinder 3 along the insertion groove 305 so that the insertion support rod 202 enters the limiting groove 306. Rotate the insertion support rod 202 along the limiting horizontal groove 307 to the intersection of the limiting horizontal groove 307 and the limiting vertical groove 308. Pull down the insertion support rod 202 and insert it into the limiting vertical groove 308, thereby achieving a fixed connection between the insulating rod 2 and the transition cylinder 3.

[0031] Then, the frame 101 is attached to the cable, and the insulating rod 2 is rotated to make the lifting threaded rod 102 push the top plate 103 upward, pressing the cable and fixing the wire clamp 1 to the cable. Next, the insulating rod 2 is pushed towards the wire clamp 1, so that the plug-in support rod 202 slides out of the limiting vertical groove 308, and the plug-in support rod 202 is rotated to face the plug-in groove 305. The plug-in support rod 202 is pulled out along the plug-in groove 305, so that the insulating rod 2 is separated from the transition cylinder 3. Finally, the same insulating rod 2 is inserted into different transition cylinders 3 in the same way to realize the installation and disassembly of the two.

[0032] By setting a transition cylinder 3 between the wire head 1 and the insulating rod 2, one insulating rod 2 can operate multiple wire clamps 1, eliminating the need to carry multiple insulating rods. This reduces the load on workers and their labor intensity, thereby effectively improving travel speed while ensuring maintenance efficiency. Furthermore, the transition cylinder 3 has a simple overall structure, is easy to install, and is small in size, making it easy to carry and promoting its widespread application.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
