Description

Technical Field

[0001] The utility model belongs to the technical field of electric power engineering, and in particular relates to a grounding rod for electric power engineering. Background Art

[0002] Grounding rods, also known as grounding electrodes and grounding grids, are designed and produced based on the theory of improving the internal conductivity of the grounding conductor and reducing the external soil resistivity of the grounding conductor. When the grounding resistance value does not meet the requirements, it may be necessary to check the state of the grounding pin to see if the performance has been degraded due to corrosion or other reasons. It may be necessary to replace or overhaul to restore a good grounding effect. After a long period of use, the grounding pin may be severely corroded or damaged. At this time, it needs to be removed and replaced to ensure the reliability of the grounding system.

[0003] The existing grounding rod can be removed by directly pulling it out. In some cases, a loosening agent (such as a lubricant, a rust inhibitor, etc.) can be used to help loosen the connection between the grounding needle and the soil. The loosening agent is sprayed on the ground to allow the loosening agent to penetrate and take effect, and then the grounding needle is tried to be pulled out. However, since the grounding rod is inserted into the soil for a long time during use, the penetration efficiency of the loosening agent is slow, resulting in low efficiency. If the grounding rod is pulled out directly, the outer wall of the grounding rod will be corroded when it is used in the soil for a long time, resulting in a large friction between the grounding rod and the soil, which makes it inconvenient to pull it out, and thus it is inconvenient for the staff to quickly take it out for replacement. Utility Model Content

[0005] The utility model provides the following technical solution: it comprises a fixing rod, the outer wall of the fixing rod is fixedly connected with a fixing ring, the fixing ring is rotatably connected with a rotating sleeve matching the outer wall of the fixing rod, the rotating sleeve and the fixing rod are respectively provided with corresponding outgoing liquid holes and inner liquid holes, the top of the fixing rod is fixedly connected with a top plate, the top plate is fixedly connected with a connecting ring, the connecting ring is clamped and connected with a sealing plate, the bottom end of the sealing plate is fixedly connected with a connecting block, the fixing rod is rotatably connected with a center rod, the top of the center rod is clamped with the bottom of the connecting block, the outer wall of the fixing rod is provided with a clearance hole corresponding to the rotating sleeve, a connecting rod is fixedly connected between the rotating sleeve and the center rod, and the connecting rod is slidably connected to the inner wall of the clearance hole.

[0006] Wherein, a clearance groove is provided on the top of the top plate, the inner wall of the clearance groove is rotatably connected to a rotating rod, and an arc-shaped plate is fixedly connected to the rotating rod.

[0007] Among them, a clamping block is fixedly connected to the bottom end of the connecting block, a limiting hole matching the clamping block is opened on the top of the center rod, a rotating block is fixedly connected to the bottom of the center rod, and the rotating block is rotatably connected to the bottom of the inner wall of the fixed rod.

[0008] Wherein, a conical sleeve is fixedly connected to the bottom end of the rotating sleeve, and the conical sleeve is rotatably connected to the outer wall of the fixed rod.

[0009] Wherein, an annular groove is provided on the rotating sleeve and the fixed ring, and an annular plate matching the annular groove is fixedly connected to the fixed rod and the rotating sleeve.

[0010] The beneficial effect of the utility model is that the center rod is rotated at the center of the fixed rod, and the connecting rod can slide on the inner wall of the giving way hole, so that when the center rod is rotated, the rotating sleeve can be adjusted to rotate within a certain range, so that the outgoing liquid hole opened on the rotating sleeve and the inner liquid hole opened on the fixed rod can be misaligned after long-term use, which is convenient for the loosening agent to quickly penetrate into the soil through the fixed rod, the inner liquid hole and the outgoing liquid hole, avoiding the need to add the loosening agent on the soil surface to make it slowly penetrate into the soil when using the loosening agent, and the efficiency of pulling out the fixed rod is low.

DETAILED DESCRIPTION

[0018] See also Figures 1-5 The utility model provides the following technical solutions: it includes a fixed rod 1, a fixed ring 3 is fixedly connected to the outer wall of the fixed rod 1, a rotating sleeve 31 matching the outer wall of the fixed rod 1 is rotatably connected to the fixed ring 3, and corresponding outgoing liquid holes 32 and internal liquid holes 33 are respectively provided on the rotating sleeve 31 and the fixed rod 1, a top plate 11 is fixedly connected to the top of the fixed rod 1, a connecting ring 13 is fixedly connected to the top plate 11, a sealing plate 2 is snap-connected to the connecting ring 13, a connecting block 21 is fixedly connected to the bottom end of the sealing plate 2, a center rod 23 is rotatably connected to the fixed rod 1, the top of the center rod 23 is snap-connected to the bottom of the connecting block 21, a clearance hole 25 corresponding to the rotating sleeve 31 is provided on the outer wall of the fixed rod 1, a connecting rod 24 is fixedly connected between the rotating sleeve 31 and the center rod 23, and the connecting rod 24 is slidably connected to the inner wall of the clearance hole 25.

[0019] In this implementation: The fixed rod 1 is used to introduce current into the ground by inserting the device into the soil when using the device. When the fixed rod 1 is inserted into the soil, the fixing ring 3 fixedly connected to the outer wall of the fixed rod 1 can enter the ground soil synchronously with it. Through the rotating sleeve 31 rotatably connected to the bottom of the fixing ring 3, it can fit with the outer wall of the fixed rod 1. With the bottom of the rotating sleeve 31 being conical, it is convenient to reduce the resistance of the fixing ring 3 to the insertion of the fixed rod 1 into the soil when inserting the fixed rod 1 into the soil. The external liquid outlet hole 32 opened on the fixing ring 3 corresponds to the internal liquid outlet hole 33 opened on the outer wall of the fixed rod 1. When inserting the fixed rod 1 into the soil, at this time, the central rod 23 rotatably connected to the center of the fixed rod 1 can be used. The connecting rod 24 fixedly connected to the outer wall of the central rod 23 passes through the relief hole 25 opened on the outer wall of the fixed rod 1, so that one end of it can be fixedly connected to the inside of the rotating sleeve 31. When the central rod 23 rotates, the connecting rod 24 can slide synchronously in the relief hole 25. Although the opening position of the relief hole 25 is limited, while ensuring that the whole fixed rod 1 will not break, it can drive the rotating sleeve 31 to rotate to a certain extent. When it is necessary to insert the fixed rod 1 into the soil, at this time, by rotating the central rod 23, the rotating sleeve 31 can rotate, so that the external liquid outlet hole 32 and the internal liquid outlet hole 33 can be misaligned to close the inner cavity of the fixed rod 1. The top plate 11 fixedly connected to the top of the fixed rod 1 is used to be above the ground, which is convenient for the staff to pull out and insert the fixed rod 1 into the soil. The connecting ring 13 fixedly connected to the inside of the top plate 11 is communicated with the inner cavity of the fixed rod 1. During normal use, the sealing plate 2 can be inserted into the inner wall of the connecting ring 13 through the connecting block 21 fixedly connected to its bottom end, so that the sealing plate 2 is engaged with the connecting ring 13 to close the top of the top plate 11. While protecting the inner cavity of the fixed rod 1, the connecting block 21 can be engaged with the top of the central rod 23. After being engaged, the staff can drive the connecting block 21 and the central rod 23 to rotate by rotating the sealing plate 2, so that the central rod 23 can drive the position of the rotating sleeve 31 to be adjusted. When it is necessary to pull out the fixed rod 1, at this time, by rotating the sealing plate 2, the central rod 23 drives the connecting rod 24 to make the rotating sleeve 31 rotate below the fixing ring 3, so that the external liquid outlet hole 32 can communicate with the internal liquid outlet hole 33 at this time. Then, by separating the sealing plate 2 from the top plate 11 and adding the loosening agent into the fixed rod 1, the loosening agent can penetrate outward through the external liquid outlet hole 32 and the internal liquid outlet hole 33, so that the soil around the fixed rod 1 can be quickly loosened, which is convenient for pulling out the fixed rod 1, thus facilitating the staff to carry out the disassembly and replacement work, and avoiding the low efficiency of adding the loosening agent on the soil surface and making it slowly penetrate into the soil when using the loosening agent.

[0020] A relief groove 12 is provided at the top of the top plate 11. A rotating rod 141 is rotatably connected to the inner wall of the relief groove 12, and an arc-shaped plate 14 is fixedly connected to the rotating rod 141. The relief groove 12 provided at the top of the top plate 11 is used to make way for the installation of the arc-shaped plate 14. The arc-shaped plate 14 is hinged to the inner wall of the relief groove 12 under the connection of the rotating rod 141. After the sealing plate 2 is separated from the arc-shaped plate 14, it can rotate. By lifting the arc-shaped plate 14, it is convenient to pull out the whole device from the soil.

[0021] A clamping block 22 is fixedly connected to the bottom end of the connecting block 21. A limiting hole 231 matching the clamping block 22 is provided at the top of the central rod 23. A rotating block 26 is fixedly connected to the bottom of the central rod 23, and the rotating block 26 is rotatably connected to the bottom inner wall of the fixed rod 1. The clamping block 22 fixedly connected to the bottom end of the connecting block 21 is used to engage with the limiting hole 231 provided at the top of the central rod 23, which is convenient for adjusting the position of the central rod 23 so that it can rotate, thereby rotating the connecting rod 24 and the fixed ring 3 to adjust the position of the rotating sleeve 31. The bottom of the central rod 23 rotates on the bottom inner wall of the fixed rod 1 through the rotating block 26, so that the central rod 23 is rotatably connected at the center of the fixed rod 1, ensuring that the connecting rod 24 can slide in the relief hole 25 and rotate the rotating sleeve 31.

[0022] A conical sleeve 313 is fixedly connected to the bottom end of the rotating sleeve 31, and the conical sleeve 313 is rotatably connected to the outer wall of the fixed rod 1. The conical sleeve 313 is conical. The conical sleeve 313 rotates on the outer wall of the fixed rod 1, so that when the whole device is inserted into the soil, the conical sleeve 313 can facilitate the synchronous insertion of the rotating sleeve 31 and the fixed rod 1 into the soil.

[0023] Annular grooves 312 are provided on both the rotating sleeve 31 and the fixed ring 3, and annular plates 311 matching the annular grooves 312 are fixedly connected to the fixed rod 1 and the rotating sleeve 31. The annular plate 311 is used to limit the annular groove 312 provided on the inner wall of the rotating sleeve 31, so that when the rotating sleeve 31 is driven to rotate, it can be ensured that it will not rotate horizontally on the outer wall of the fixed rod 1.

[0024] Working principle and usage process of the utility model: Before inserting the fixing rod 1 into the soil, the external liquid outlet hole 32 and the internal liquid outlet hole 33 are misaligned to seal the inner cavity of the fixing rod 1. During normal use, the sealing plate 2 is engaged with the connecting ring 13 to seal the top of the top plate 11. The staff can drive the connecting block 21 and the central rod 23 to rotate by rotating the sealing plate 2, so that the central rod 23 can drive the position of the rotating sleeve 31 to be adjusted. When it is necessary to pull out the fixing rod 1, at this time, by rotating the sealing plate 2, the central rod 23 drives the connecting rod 24 to rotate the rotating sleeve 31 under the fixing ring 3, so that the external liquid outlet hole 32 can communicate with the internal liquid outlet hole 33 at this time. Then, after separating the sealing plate 2 from the top plate 11 and adding the loosening agent into the fixing rod 1, the loosening agent can penetrate outward through the external liquid outlet hole 32 and the internal liquid outlet hole 33, so that the soil around the fixing rod 1 can be quickly loosened, facilitating the pulling out of the fixing rod 1, which is beneficial for the staff to carry out the disassembly and replacement work, and avoids adding the loosening agent on the soil surface when using the loosening agent to make it slowly penetrate into the soil, with low efficiency.
