Description

Technical Field

[0001] This invention relates to the field of grounding anti-disconnection technology, specifically to a multi-point grounding anti-disconnection grounding device. Background Technology

[0002] In the operation and maintenance of power systems, grounding devices are key facilities to ensure the safety of operators and the normal operation of equipment. Traditional grounding devices generally have problems such as loose connections, easy detachment, and cumbersome operation, which bring serious safety hazards to power maintenance work. Moreover, with the expansion of power grid scale and the increase of voltage level, the risk of grounding failure is becoming increasingly prominent, which puts forward higher requirements for anti-detachment technology.

[0003] Currently, in multi-point grounding scenarios, traditional methods require grounding multiple cables one by one, which is a cumbersome process of repeated disassembly and assembly. Especially in high-rise buildings, the increased length of the grounding wire leads to greater weight and difficulty in carrying, and operators face greater risks when working at heights. In addition, once the grounding device falls off, it not only loses its protective function, but may also trigger a chain reaction such as short circuit accidents and protection malfunctions.

[0004] To address the aforementioned issues, we propose a multi-point grounding anti-disconnection grounding device. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-point grounding anti-disconnection grounding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-point grounding anti-derailment grounding device, comprising a grounding box; the grounding box includes a grounding base disposed at the bottom and a grounding component and an anti-derailment component disposed inside, the top of the grounding base is fixed to the bottom of the grounding component, and the grounding base is fixedly connected to the grounding base, the grounding component includes a connector fixedly connected to the grounding base and an insulating plate disposed on the connector, the anti-derailment component is disposed corresponding to the insulating plate, and the anti-derailment component is fixedly disposed against the inner wall of the grounding box, and grounding wires are interspersed inside both the insulating plate and the anti-derailment component.

[0007] Preferably, an acrylic plate is installed on the front end of the front surface of the grounding box. The acrylic plate is inserted into the grounding box in a plug-in manner to achieve a seal.

[0008] Preferably, the top of the grounding base includes a lower connecting plate, the upper surface of which is distributed with internally threaded posts, and the top of the connector includes an upper connecting plate, the upper connecting plate having screw holes corresponding to the lower connecting plate.

[0009] Preferably, the top of the lower connecting plate is embedded in the bottom of the upper connecting plate.

[0010] Preferably, the top of the upper connecting plate has connecting posts arranged symmetrically on the left and right, with the connecting post on the left being lower than the connecting post on the right. Both connecting posts are embedded with grounding copper busbars, and sheath overvoltage protectors are evenly distributed on the grounding copper busbars. The bottom of each sheath overvoltage protector is located on the insulating plate.

[0011] Preferably, the sheath overvoltage protector and the grounding copper busbar are arranged adjacently on the side of the insulating plate, and a first baffle is provided on the side of the insulating plate between two adjacent sheath overvoltage protectors and grounding copper busbars.

[0012] Preferably, a second connecting pipe is provided on the top of the insulating plate near the inner wall of the grounding box, and a first connecting pipe is provided inside the anti-detachment component passing through the grounding box. The anti-detachment component is also provided with an mounting plate on the outer wall of the first connecting pipe. The first connecting pipe and the second connecting pipe are correspondingly provided, and each is provided with a second baffle, a first anti-detachment tube and a second anti-detachment tube. The second baffle is arranged in a grid-like horizontal arrangement, and the first anti-detachment tube and the second anti-detachment tube are arranged in sequence. The first anti-detachment tube and the second anti-detachment tube are both arranged in an L-shape.

[0013] Preferably, the first anti-detachment tube includes a first wire-fixing groove disposed at both ends of the L-shape, and a first wire-tightening assembly is disposed in the first wire-fixing groove. The second anti-detachment tube includes a second wire-fixing groove disposed at both ends of the L-shape, and a second wire-tightening assembly is disposed in the second wire-fixing groove.

[0014] Preferably, the first and second tensioning assemblies are both tapered at their front ends and have cable clamping blocks inserted into each other. The bottom of the cable clamping blocks is provided with anti-slip pads, and the rear cylindrical sections of the first and second tensioning assemblies are both sleeved with positioning top springs.

[0015] Preferably, the cable clamping block has a limiting groove at the front tapered portion of the first and second tensioning components. A limiting block is provided inside each limiting groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

Grounding wires are inserted through the second connecting pipe on the grounding component and the first connecting pipe on the anti-detachment component. The grounding wires are connected to the grounding copper busbar through the sheath overvoltage protector on the insulating plate and the grounding base to complete the overall grounding. This simplifies the process of multi-point synchronous grounding operation.

[0017] 2. This invention utilizes an external anti-detachment component on the grounding box in conjunction with an internal insulating plate to stably clamp and fix the grounding cable, ensuring that the grounding cable will not loosen from the self-locking cable device. Simultaneously, after multiple grounding cables are inserted into the first connecting pipe, the first and second anti-detachment pipes, through their internal first and second tightening components, can counteract the loosening force of the grounding cables, keeping them firmly fixed inside the first and second anti-detachment pipes. Furthermore, by correspondingly positioning the first and second anti-detachment pipes on the insulating plate with the anti-detachment components, the grounding cables can be connected to the grounding base. When pulling the grounding cable, cable clamping blocks within the first and second tightening components can secure the grounding cable, preventing it from loosening from the first and second anti-detachment pipes. This invention is convenient to use, reduces labor intensity, simplifies the installation and connection steps of the grounding cable and grounding terminal, and improves the flexibility and adaptability of the device.

Example 1

[0021] like Figure 1-4 As shown, this embodiment discloses a multi-point grounding anti-derailment grounding device, including a grounding box 1; the grounding box 1 includes a grounding base 4 disposed at the bottom and a grounding component 3 and an anti-derailment component 7 disposed inside.

Grounding wires are interspersed inside both the insulating plate 6 and the anti-derailment component 7.

[0022] In this embodiment, an acrylic plate 2 is installed on the front end of the front surface of the grounding box 1. The acrylic plate 2 is inserted into the grounding box 1 in a plug-in manner to achieve sealing of the multi-point synchronous grounding inside the grounding box 1.

[0023] In this embodiment, the grounding component 3 includes a connector 5 fixedly connected to the grounding base 4 and an insulating plate 6 disposed on the connector 5.

The cable clamping block 25 is provided with a limiting groove 27 at the front tapered part of the first tensioning assembly 20 and the second tensioning assembly 22. A limiting block 29 is provided inside the limiting groove 27. An upper limit tension spring 28 is provided on the upper surface of the limiting block 29.

[0027] Specifically, firstly, during use, the grounding cable is passed through the first connecting pipe 8 corresponding to the anti-disconnection component 7 on the rear side of the grounding box 1. After passing through the first connecting pipe 8, the grounding cable passes through the second connecting pipe 11 on the rear side of the upper insulating plate 6 of the grounding component 3 in the grounding box 1 and connects to the front sheath overvoltage protector 9 of the insulating plate 6. At the same time, there are several first connecting pipes 8 and corresponding second connecting pipes 11 for multi-point synchronous grounding operation. Simultaneously, the first connecting pipe 8 and the second connecting pipe 11 are correspondingly arranged, and each is equipped with a second baffle 16, a first anti-detachment pipe 17, and a second anti-detachment pipe 18. The second baffle 16 is arranged horizontally in a grid pattern, with the first anti-detachment pipe 17 and the second anti-detachment pipe 18 arranged sequentially. Both the first anti-detachment pipe 17 and the second anti-detachment pipe 18 are L-shaped. The first anti-detachment pipe 17 includes a first wire-fixing groove 21 at both ends of the L-shape, and a first wire-tightening assembly 20 is arranged in the first wire-fixing groove 21.

The front ends of both the first wire-tightening assembly 20 and the second wire-tightening assembly 22 are tapered and inserted with cable clamps. The bottom of the cable clamping block 25 is provided with an anti-slip pad 26.

The upper end of the upper limit tension spring 28 is fixed to the top of the limit groove 27. The lower surface of the limit block 29 is provided with a lower limit tension spring 30. The lower end of the lower limit tension spring 30 is fixed to the bottom of the limit groove 27, so as to ensure that the grounding cable is fixed and that the grounding cable will not come loose from the inside of the first anti-detachment tube 17 and the second anti-detachment tube 18. Furthermore, the sheath overvoltage protectors 9 are arranged adjacently on the side of the insulating plate 6. A first baffle 12 is provided on the side of the insulating plate 6 between two adjacent sheath overvoltage protectors 9 and the grounding copper busbar 10.

Then, the grounding terminal at the top of the sheath overvoltage protector 9 is connected to the grounding copper busbar 10, and the grounding copper busbar 10 is connected to the connecting posts 14 symmetrically arranged on the upper connecting plate 13 of the connector 5. This is used to integrate the two grounding copper busbars 10 into a unified grounding base 4 to achieve reliable grounding of the power supply site. Finally, an acrylic plate 2 is installed on the front end of the front surface of the grounding box 1, so that the acrylic plate 2 is inserted into the grounding box 1 in a plug-in manner to achieve sealing of the multi-point synchronous grounding inside the grounding box 1.
