Description

Technical Field

[0001] This utility model relates to the field of substation grounding grid technology, and in particular to a grounding grid for a box-type substation. Background Technology

[0002] As a key power distribution facility in the power system, the grounding system of the prefabricated substation not only requires good conductivity, but also needs to ensure structural stability and durability. However, in actual operation, the connection and installation of the grounding rod and the grounding body are often affected by a variety of factors, which increases the difficulty of operation.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the grounding electrode is usually made of copper or steel, which has good conductivity and corrosion resistance, but the matching grounding rod may be different in material, size and shape, making it difficult to fit the connection tightly. In addition, since the grounding system needs to withstand the current and voltage for a long time, loosening or corrosion of the connection may lead to an increase in grounding resistance and affect the grounding effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the grounding rod is inconvenient to install. Therefore, we propose a grounding grid for box-type substations.

[0005] To achieve the above objectives, this application adopts the following technical solution: a grounding grid for a box-type substation, comprising a grounding body, a grounding wire installed at the top of the grounding body, an adjusting block fixedly connected to the bottom of the grounding body, a rotating column slidably connected inside the adjusting block, a grounding rod disposed inside the rotating column, arc-shaped blocks fixedly connected to both sides of the inner wall of the adjusting block, adjusting grooves opened on both sides of the rotating column, a through hole opened on the side of the adjusting groove near the grounding rod, an insertion hole opened inside the grounding rod, a push block slidably connected inside the adjusting groove, and an insertion rod fixedly connected to the side of the push block near the grounding rod.

[0006] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0007] Preferably, sliding grooves are provided on both sides of the adjustment groove, and sliders are fixedly connected to both sides of the push block, with the surface of the sliders slidingly connected to the inside of the sliding grooves.

[0008] Preferably, a storage spring is fixedly connected to the side of the push block near the grounding rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0009] Preferably, the surface of the rotating column is provided with annular grooves, and there are two annular grooves. The inner wall of the adjusting block is fixedly connected with an annular block.

[0010] Preferably, threaded rods are provided on both sides of the adjusting block, and threaded holes are provided on both sides of the rotating column.

[0011] Preferably, a sealing gasket is provided at the top of the inside of the adjusting block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator rotates the rotating column, causing the rotating column to move the push block and the insertion rod, and the push block to contact the arc-shaped block. When the push block contacts the thicker end of the arc-shaped block, the arc-shaped block squeezes the push block to move into the adjustment groove, and drives the insertion rod to be inserted into the insertion hole, thereby achieving the function of conveniently installing the grounding rod.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a grounding grid for a box-type substation, including a grounding body 1, a grounding wire 2 installed at the top of the grounding body 1, an adjusting block 3 fixedly connected to the bottom of the grounding body 1, a rotating column 4 slidably connected inside the adjusting block 3, a grounding rod 5 installed inside the rotating column 4, arc-shaped blocks 6 fixedly connected to both sides of the inner wall of the adjusting block 3, adjusting grooves 7 opened on both sides of the rotating column 4, a through hole 8 opened on the side of the adjusting groove 7 near the grounding rod 5, an insertion hole 9 opened inside the grounding rod 5, a push block 10 slidably connected inside the adjusting groove 7, and an insertion rod 11 fixedly connected to the side of the push block 10 near the grounding rod 5. By rotating the rotating column 4, the operator moves the push block 10 and the insertion rod 11, and the push block 10 contacts the arc-shaped block 6. When the push block 10 contacts the thicker end of the arc-shaped block 6, the arc-shaped block 6 squeezes the push block 10 into the adjusting groove 7 and moves the insertion rod 11 into the insertion hole 9, thereby achieving the function of convenient installation of the grounding rod 5.

[0022] Reference Figure 4 and Figure 5 As shown in this embodiment: the size of the insertion rod 11 is adapted to the size of the insertion hole 9, and the surface of the insertion rod 11 is inserted into the interior of the insertion hole 9. By adapting the size of the insertion rod 11 to the size of the insertion hole 9, the stability and tightness of the insertion rod 11 when inserted into the insertion hole 9 are ensured, so as to guide the correct insertion direction of the insertion rod 11, avoid damage caused by misoperation, ensure a more secure connection between the insertion rod 11 and the insertion hole 9, and prevent accidental detachment during use.

[0023] Reference Figure 5 As shown in this embodiment: sliding grooves 13 are provided on both sides of the adjustment groove 7, and sliders 14 are fixedly connected to both sides of the push block 10. The surface of the slider 14 is slidably connected to the inside of the sliding groove 13. When the operator moves the push block 10, the push block 10 drives the slider 14 to slide inside the sliding groove 13. Through the above setting, the slider 14 can move smoothly in the sliding groove 13, thereby realizing the precise adjustment of the position of the push block 10. In addition, the sliding connection design between the slider 14 and the sliding groove 13 not only improves the flexibility of operation, but also enhances the durability of the device. In practical applications, this structural design can effectively reduce wear caused by frequent operation and extend the service life of the equipment.

[0024] Reference Figure 4As shown in this embodiment: a storage spring 12 is fixedly connected to the side of the push block 10 near the grounding rod 5, and the side of the storage spring 12 away from the push block 10 is fixedly connected to the inside of the adjustment groove 7. When the push block 10 contacts the thicker end of the arc block 6, the push block 10 compresses the storage spring 12 to store force, and at the same time, the insertion rod 11 is inserted into the insertion hole 9 for fixation. When the operator rotates the rotating column 4, the contact between the push block 10 and the arc block 6 is canceled, and the storage spring 12 quickly pushes the push block 10 under the action of the rebound force, and drives the insertion rod 11 to release the limit between it and the insertion hole 9.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: the surface of the rotating column 4 is provided with annular grooves 15, and there are two annular grooves 15. The inner wall of the adjusting block 3 is fixedly connected with annular blocks 16. When the operator rotates the rotating column 4, the annular grooves 15 on the surface of the rotating column 4 rotate along the trajectory of the annular blocks 16, and support and guide the movement trajectory of the rotating column 4, ensuring the stability and accuracy during the rotation process.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: threaded rods 17 are provided on both sides of the adjusting block 3, and threaded holes 18 are provided on both sides of the rotating column 4. The operator inserts the threaded rods 17 into the threaded holes 18 to fix the position of the rotating column 4, and at the same time avoids the unstable contact between the push block 10 and the arc block 6 caused by the rotation of the rotating column 4 due to external factors.

[0027] Reference Figure 4 As shown in this embodiment: a sealing gasket 19 is provided at the top of the inside of the adjusting block 3. By providing a sealing gasket 19 at the top of the inside of the adjusting block 3, the direct collision of the push block 10 inside the adjusting block 3 can be effectively prevented, thereby reducing the generation of noise. In addition, the elastic properties of the sealing gasket 19 can also absorb vibration to a certain extent, further improving the stability and reliability of the entire device.

[0028] Working principle: By rotating the rotating column 4, the operator moves the push block 10 and the insertion rod 11, bringing the push block 10 into contact with the arc-shaped block 6. When the push block 10 contacts the thicker end of the arc-shaped block 6, the arc-shaped block 6 pushes the push block 10 into the adjusting groove 7, causing the insertion rod 11 to be inserted into the socket 9. This facilitates the installation of the grounding rod 5. The matching size of the insertion rod 11 with the socket 9 ensures the stability and tightness of the insertion rod 11, guiding it to the correct insertion direction and preventing misoperation. To prevent damage caused by accidental detachment, the connection between the insertion rod 11 and the insertion hole 9 is made more secure. When the operator moves the push block 10, the push block 10 drives the slider 14 to slide inside the slide groove 13. Through the above settings, the slider 14 can move smoothly within the slide groove 13, thereby achieving precise adjustment of the position of the push block 10. In addition, the sliding connection design between the slider 14 and the slide groove 13 not only improves the flexibility of operation but also enhances the durability of the device. In practical applications, this structural design can effectively reduce wear caused by frequent operation. To extend the service life of the equipment, when the push block 10 contacts the thicker end of the arc-shaped block 6, the push block 10 compresses the energy storage spring 12 to store energy, simultaneously causing the insertion rod 11 to be inserted into the insertion hole 9 for fixation. When the operator rotates the rotating column 4, causing the contact between the push block 10 and the arc-shaped block 6 to be released, the energy storage spring 12 quickly pushes the push block 10 under the action of its rebound force, and drives the insertion rod 11 to release the limit between itself and the insertion hole 9. When the operator rotates the rotating column 4, the annular groove 15 opened on the surface of the rotating column 4 rotates along the trajectory of the annular block 16, and the rotating column 4... The moving trajectory provides support and guidance, ensuring stability and accuracy during rotation. The operator inserts the threaded rod 17 into the threaded hole 18 to fix the position of the rotating column 4, while preventing unstable contact between the push block 10 and the arc-shaped block 6 caused by the rotation of the rotating column 4 due to external factors. The sealing gasket 19 at the top of the adjusting block 3 effectively prevents the push block 10 from directly colliding inside the adjusting block 3, thereby reducing noise generation. In addition, the elastic properties of the sealing gasket 19 can also absorb vibration to a certain extent, further improving the stability and reliability of the entire device.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
