Description

Technical Field

[0001] This utility model relates to the field of grounding device technology, and more specifically to an electrical grounding device for leakage protection. Background Technology

[0002] Grounding rods are used during power maintenance to temporarily ground the three-phase overhead lines or busbars on the power supply side to prevent sudden power energization and thus prevent personal injury caused by sudden power surges. Usually, three rods are used together.

[0003] Currently, grounding rods require workers to carry them and climb to the top of the utility pole before attaching them to the cable. However, existing grounding rods lack proper securing mechanisms, requiring workers to tie three rods together with ropes before carrying them to the pole and then untying them. This is cumbersome, and the ropes are prone to loosening during the climb, causing the grounding rods to fall. This results in low usability. Therefore, there is an urgent need to design a leakage protection electrical grounding device to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electrical grounding device for leakage protection to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: an electrical grounding device for leakage protection, comprising three grounding rod bodies, a first connecting component, and two second connecting components, wherein one grounding rod body is fixedly installed in the first connecting component, and the other two grounding rod bodies are respectively fixedly installed in the two second connecting components, and both second connecting components are snapped into the first connecting component;

[0006] The first connecting component includes a first connecting block, in which one grounding rod body is fixedly installed. The second connecting component includes a second connecting block, in which two other grounding rod bodies are fixedly installed in the two second connecting blocks respectively.

[0007] Furthermore, both the first connecting block and the second connecting block have a circular hole at their top, and the grounding rod body is fixedly installed inside the circular hole.

[0008] Furthermore, the second connecting component also includes a connecting post, which is fixedly installed at the end of the second connecting block that is in contact with the first connecting block. The top of the first connecting block has two connecting grooves, and the connecting post is adapted to the connecting grooves.

[0009] Furthermore, the first connecting assembly also includes two springs and two locking blocks. The outer walls of both ends of the first connecting block are provided with sliding grooves. The two springs are respectively fixedly installed on the inner walls of one end of the two sliding grooves. The two locking blocks are respectively slidably installed in the two sliding grooves. The two locking blocks are respectively fixedly connected to the two springs. The ends of the two second connecting blocks that are in contact with the first connecting block are provided with locking slots, and the locking blocks and locking slots are adapted to each other.

[0010] Furthermore, the first connecting component also includes a T-shaped grip, which is fixedly installed on the arc-shaped outer wall of the first connecting block.

[0011] Furthermore, the outer circumference of the T-shaped grip is equidistantly distributed with several anti-slip strips, which are made of rubber.

[0012] Furthermore, the bottom of the connecting post is chamfered.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model, through the provision of a first connecting component and a second connecting component, allows the connecting post and the locking block to limit the second connecting block in the horizontal and vertical directions respectively when the second connecting block is connected to the first connecting block, thereby locking the second connecting block onto the first connecting block. This enables the three grounding rod bodies to be connected together and carried by the staff without loosening or falling off, thus improving its ease of use. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 4 The present invention will be further described below.

[0022] An electrical grounding device for leakage protection includes three grounding rod bodies 1, a first connecting component 2, and two second connecting components 3. One grounding rod body 1 is fixedly installed in the first connecting component 2, and the other two grounding rod bodies 1 are respectively fixedly installed in the two second connecting components 3. Both second connecting components 3 are snapped into the first connecting component 2.

[0023] The first connecting component 2 includes a first connecting block 201, in which one grounding rod body 1 is fixedly installed. The second connecting component 3 includes a second connecting block 301, in which two other grounding rod bodies 1 are fixedly installed in the two second connecting blocks 301 respectively.

[0024] Specifically, the top of the first connecting block 201 and the second connecting block 301 are both provided with a round hole 4, and the grounding rod body 1 is fixedly installed in the round hole 4.

[0025] Specifically, the second connecting component 3 also includes a connecting post 302, which is fixedly installed at the end of the second connecting block 301 that is in contact with the first connecting block 201. The top of the first connecting block 201 has two connecting grooves 202, and the connecting post 302 is adapted to the connecting grooves 202.

[0026] Specifically, the first connecting component 2 also includes two springs 204 and two locking blocks 205. The outer walls of both ends of the first connecting block 201 are provided with sliding grooves 203. The two springs 204 are respectively fixedly installed on the inner walls of one end of the two sliding grooves 203. The two locking blocks 205 are respectively slidably installed in the two sliding grooves 203. The two locking blocks 205 are respectively fixedly connected to the two springs 204. The ends of the two second connecting blocks 301 that are in contact with the first connecting block 201 are provided with locking slots 303. The locking blocks 205 are adapted to the locking slots 303.

[0027] Specifically, the first connecting component 2 also includes a T-shaped grip 206, which is fixedly installed on the arc-shaped outer wall of the first connecting block 201.

[0028] Specifically, the outer circumference of the T-shaped grip 206 is equidistantly distributed with several anti-slip strips 207, which are made of rubber.

[0029] In this implementation scheme, the anti-slip strip 207 increases the friction between the worker's hand and the T-shaped grip 206, making the T-shaped grip easier to hold.

[0030] Specifically, the bottom of the connecting post 302 is provided with a chamfer 304.

[0031] In this embodiment, the chamfer 304 allows the connecting post 302 to enter the connecting groove 202 more smoothly when it is engaged with the connecting groove 202.

[0032] Working principle: In the initial state, the connecting blocks 302 on the two second connecting blocks 301 respectively engage with the two connecting slots 202 on the first connecting block 201. The two locking blocks 205 are pushed by the two springs 204 and engaged with the two locking slots 303. Therefore, the two second connecting blocks 301 are locked. At this time, the three grounding rod bodies 1 can be carried at the same time without falling apart. After carrying the three grounding rod bodies 1 to the top of the utility pole, hold the T-handle 206, slide the two locking blocks 205 in sequence and compress the springs 204 to make the locking blocks 205 disengage from the locking slots 303. Then slide the grounding rod body 1 fixedly installed in the second connecting block 301, which can drive the second connecting block 301 and the connecting post 3. 02. After sliding the connecting post 302 out of the connecting groove 202, the two grounding rod bodies 1 fixedly installed in the second connecting block 301 can be removed. After use, align the connecting post 302 with the connecting groove 202 from the top of the first connecting block 201 and press it down. When the second connecting block 301 slides down, it will press the locking block 205 and the spring 204, causing the locking block 205 to retract into the sliding groove 203. When the locking groove 303 on the second connecting block 301 slides down to correspond with the locking block 205, the spring 204 will release and push the locking block 205 to engage in the locking groove 303, thereby relocking the second connecting block 301 and locking the grounding rod body 1 fixedly installed in the second connecting block 301.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
