Description

Technical Field

[0001] The present invention relates to the technical field of conductive connection, and particularly relates to a grounding rod structure that is convenient for installation and disassembly. Background Art

[0002] Grounding of the grounding wire in power maintenance is a very important safety measure. The purpose of grounding is to prevent current from passing through the human body and causing harm, and at the same time guide the excess current in the power system to the ground to ensure the safety of equipment and personnel. When grounding, one end of the grounding wire is connected to the equipment or high-voltage wire to be grounded, and the other end of the grounding wire has a grounding rod inserted into the ground to a certain depth, so as to introduce the current into the ground through the grounding rod.

[0003] For example, the publication number is: CN111446560B, and the name is: A grounding rod. The grounding rod body is provided with protruding spiral textures, and the head of the grounding rod is a four-edge steel knife structure arranged in a cross shape, which has the advantages of quick grounding, achieving grounding with a smaller grounding resistance, and improving the efficiency of driving into the ground; the publication number is: CN218123735U, and the name is: A telescopic grounding rod. This grounding rod includes a telescopic tube body, one end is sleeved with an anti-slip sleeve: a power connection frame, which is installed on the telescopic tube body: a power connection component, one end is located inside the power connection frame, and the other end is slidably inserted into the telescopic tube body. This grounding rod optimizes the locking method of the telescopic grounding rod and has strong practicability.

[0004] Existing grounding rods are mostly fixed or telescopic. Fixed grounding rods are usually not convenient for adjusting the length, resulting in inconvenient placement of the longer length during carrying or transportation. Although telescopic grounding rods can adjust the length, their outer surfaces are relatively smooth, which is beneficial for inserting into the ground, but there is also a risk of being randomly pulled out. Moreover, the cross-section of the telescopic grounding rod is mostly annular and is a hollow structure, with a small cross-sectional area, which affects the current flow effect and the strength is not high. Therefore, we propose a grounding rod structure that is convenient for installation and disassembly. Summary of the Invention

[0051] Please refer to Figures 1-8 , the present invention provides a technical solution: a grounding rod structure that is easy to install and disassemble is the same as that in Embodiment 1, and its distinguishing technical features are:

[0052] On one side of the guiding block 605, there is a pushing spring 607 for pushing it to reset, and the opposite side walls of the convex block 604 do not have the arc surface 606.

[0053] The working principle and usage process of the present invention: When in use, every two adjacent folding rods 2 are rotationally matched through the rotating column 202 and the connecting block 203, which is convenient for folding a plurality of folding rods 2 to reduce the length and facilitate transportation after collection. When inserting the folding rod 2 into the ground, the driving rod 101 can be pushed downward so that the threaded block 102 at the top of the driving rod 101 is threadedly engaged with the threaded groove 103. At this time, the driving rod 101 abuts against the push rod 601 and extends from one folding rod 2 into the inner side of another folding rod 2 to abut against the push rod 601 on the inner side of the other folding rod 2. Then, the push rod 601 is inserted into the inner side of the connecting block 203 to limit the rotation between two adjacent folding rods 2, making a plurality of folding rods 2 in a straight line and straight. At this time, the plurality of folding rods 2 can be inserted deep into the soil through the tip 4. After being inserted to the predetermined depth, the threaded block 102 is further rotated downward, so that the driving rod 101 continues to push the push rod 601 to move through the threaded block 102. The convex block 604 is pushed out of the folding rod 2 by abutting against the guiding groove 603, and the convex block 604 is inserted into the soil to increase the friction between the folding rod 2 and the soil and prevent the accidental pulling out of the folding rod 2. When disassembling later, the threaded block 102 can be rotated reversely. At this time, under the elastic force of the return spring 602, the push rod 601 resets, and the folding rod 2 is driven to rotate by itself through the grounding rod head 1. Then, through the arc surface 606 on the side wall of the convex block 604, the soil abuts against the arc surface 606 to generate an external force to retract the convex block 604 into the folding rod 2, and then the plurality of folding rods 2 can be pulled out from the soil. The operation is simple.
