Abstract
Description
Technical Field
[0001] This utility model relates to the field of power grounding technology, and in particular to a grounding device with a protective structure. Background Technology
[0002] For operational and safety reasons, power systems often require connecting certain parts of the power system and its electrical equipment to the earth. This is called grounding. In a power system, "ground" refers to the conductive material of the earth whose potential at any point is conventionally taken as 0. Grounding refers to the conductive connection (metallic connection) between a circuit (equipment) and the earth or certain conductors that replace the earth. Power system grounding includes high-voltage system grounding and low-voltage system grounding. Low-voltage grounding systems are classified into five types according to grounding system: IT, TT, TN-C, TN-S, and TN-CS. Traditional grounding devices lack effective protective structures, and power lines or conductive components are easily damaged by being stepped on, crushed, or subjected to mechanical impact, affecting the working efficiency of the grounding device. Furthermore, ordinary grounding devices, such as simple metal rods, rely solely on being inserted into the ground for fixation and are easily affected by soil loosening, rainwater erosion, or external pulling forces. Therefore, those skilled in the art provide a grounding device with a protective structure to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grounding device with a protective structure.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A grounding device with a protective structure includes a square plate. A slot is formed in the middle of the top surface of the square plate. A conductive block is fixedly installed in the middle of the bottom wall of the slot. A wire-bearing hole is formed on one side of the slot. Buffer rods are fixedly installed at the four corners of the bottom wall of the slot. A top cover is fixedly installed on the top of the buffer rod. Connecting blocks are fixedly installed on both sides of the top surface of the top cover. A reflective block is fixedly installed on the top of the connecting block. A fixing component is fixedly installed in the middle of the bottom surface of the square plate.
[0005] As a further embodiment of this utility model, the fixing component includes a circular block fixedly installed in the middle of the bottom surface of the square plate, a fixing cone fixedly installed at the bottom of the circular block, connecting blocks fixedly installed on both sides of the square plate, and a fixing bolt threaded through the middle of the top surface of the connecting block.
[0006] As a further embodiment of this utility model, a semi-circular plate is fixedly installed in the middle of the top surface of the square plate, and a compression bolt is threaded through one side of the top surface of the semi-circular plate.
[0007] As a further embodiment of this utility model, one end of the compression bolt is rotatably connected to a compression block, and a flexible pad is attached to the bottom of the compression block.
[0008] As a further embodiment of this utility model, connecting holes are provided at the four corners of the top surface of the square plate, and connecting bolts are threaded through the internal threads of the connecting holes.
[0009] As a further embodiment of this invention, a damping spring is provided inside the buffer rod, and the buffer rod is slidably connected to a sliding rod inside.
[0010] As a further embodiment of this utility model, the outer surface of the square plate is covered with a waterproof membrane to increase water resistance, and the outer surface of the top cover is covered with an anti-oxidation membrane to increase anti-oxidation properties.
[0011] As a further embodiment of this utility model, the square plate has circular grooves equidistantly spaced on one side, and reinforcing ribs are provided inside the circular grooves.
[0012] The beneficial effects of this utility model are as follows: 1. By setting up a buffer rod, reflective blocks, a top cover, and a square plate, when personnel are installing the grounding device, the reflective blocks can warn outsiders at night. If the top cover is accidentally stepped on, it will move downwards, and the buffer rod will work with the top cover to cushion the downward movement. The power cord will then be protected inside the slot, thus facilitating the protection of the power cord inside the square plate.
[0013] 2. By setting up the square plate and fixing components, when personnel are installing the square plate, they can place the square plate in the designated installation position, and then press the square plate down to make the fixing cone penetrate into the ground. Then, they can tighten the fixing bolt to fix the connecting block, thereby effectively fixing the square plate. Attached Figure Description

[0017] Reference Figures 1-4 A grounding device with a protective structure includes a square plate 1. A slot is provided in the middle of the top surface of the square plate 1. A conductive block 2 is fixedly installed in the middle of the bottom wall of the slot. A wire-bearing hole is provided on one side of the slot. A semi-arc plate 8 is fixedly installed in the middle of the top surface of the square plate 1. A compression bolt 9 is threaded through one side of the top surface of the semi-arc plate 8. One end of the compression bolt 9 is rotatably connected to a compression block 10. A flexible pad is attached to the bottom of the compression block 10.
[0018] When staff need to ground the power cord, they can place the square plate 1 in the designated working position, press down on the square plate 1 to drive the fixing cone 72 into the bottom, and then tighten the fixing bolt 74 to fix the connecting block 73 to the ground, thus fixing the square plate 1 to the ground. Then, the staff can place the power cord inside the cable tie hole and tighten the squeezing bolt 9 to move the squeezing block 10 downward. The squeezing block 10 can then fix the power cord to the top of the conductive block 2. When outsiders pass by the square plate 1, the reflective block 6 can warn them. If outsiders accidentally step on the top cover 4, the buffer rod 3 can cushion the top cover 4 downward, thus facilitating effective protection of the power cord inside the square plate 1.
[0019] In this utility model, buffer rods 3 are fixedly installed at the four corners of the bottom wall of the card slot, a top cover 4 is fixedly installed on the top of the buffer rods 3, connecting blocks 5 are fixedly installed on both sides of the top surface of the top cover 4, a reflective block 6 is fixedly installed on the top of the connecting block 5, a damping spring is provided inside the buffer rods 3, and the inside of the buffer rods 3 is slidably connected to the sliding rod.
[0020] With the installation of buffer rod 3, reflective block 6, top cover 4 and square plate 1, when personnel install the grounding device, the reflective block 6 can warn outsiders at night. Subsequently, when the top cover 4 is accidentally stepped on, the top cover 4 moves downward, and then the buffer rod 3 cooperates with the top cover 4 to buffer downward, and then the power line is protected inside the slot, thus facilitating the protection of the power line inside the square plate 1.
[0021] In particular, a fixing component 7 is fixedly installed in the middle of the bottom surface of the square plate 1. The fixing component 7 includes a circular block 71 fixedly installed in the middle of the bottom surface of the square plate 1. A fixing cone 72 is fixedly installed at the bottom of the circular block 71. Connecting blocks 73 are fixedly installed on both sides of the square plate 1. A fixing bolt 74 is threaded through the middle of the top surface of the connecting block 73. Connecting holes are opened at the four corners of the top surface of the square plate 1. Connecting bolts 11 are threaded through the inside of the connecting holes.
[0022] With the square plate 1 and the fixing component 7, when personnel are installing the square plate 1, they can place the square plate 1 in the designated installation position, and then press the square plate 1 downwards to make the fixing cone 72 penetrate into the ground. Then, the fixing bolt 74 is turned to fix the connecting block 73, thereby effectively fixing the square plate 1.
[0023] In particular, the outer surface of the square plate 1 is covered with a waterproof membrane to increase waterproofness, the outer surface of the top cover 4 is covered with an anti-oxidation membrane to increase anti-oxidation, and a circular groove is provided at equal intervals on one side of the square plate 1, with reinforcing ribs provided inside the circular groove; The waterproof and anti-oxidation membranes serve to prevent slippage on the square panel 1 and the top cover 4.
[0024] Working principle: When the staff needs to ground the power cord, they can place the square plate 1 in the designated working position, press down on the square plate 1 to drive the fixing cone 72 into the bottom surface, and then tighten the fixing bolt 74 to fix the connecting block 73 to the ground, thus fixing the square plate 1 to the ground. Then, the staff can place the power cord inside the cable tie hole and tighten the squeezing bolt 9 to move the squeezing block 10 downward. The squeezing block 10 can then fix the power cord to the top of the conductive block 2. When outsiders pass by the square plate 1, the reflective block 6 can warn outsiders. If outsiders accidentally step on the top cover 4, the buffer rod 3 can cushion the top cover 4 downward, thus facilitating effective protection of the power cord inside the square plate 1.
