Abstract
Description
Technical Field
[0001] This utility model relates to the field of grounding device technology, specifically to a grounding device. Background Technology
[0002] Transmission line maintenance refers to the handling of defects found during routine inspections and various checks of the line, such as replacing aging or damaged components to restore it to normal operating conditions. Grounding devices in transmission line maintenance are installed to ensure the safety of personnel and protect equipment during the maintenance process, preventing electric shock caused by current passing through the human body and reducing the risk of equipment damage due to faults such as leakage or short circuits. The grounding devices commonly used in transmission lines are mainly connected to the transmission line by clamps. The contact between the clamps and the line conductors is often not stable enough and is easily affected by strong natural factors such as wind. External interference may cause the connection between the clamps and the conductors to loosen or even fall off, posing potential safety risks to the personnel performing maintenance work. Utility Model Content
[0003] The purpose of this utility model is to provide a grounding device to solve the problem mentioned in the background art, where the grounding devices commonly used in power transmission lines are mainly connected to the power transmission lines by a clamping method. The contact between the clamp and the line conductor is often not stable enough and is easily affected by strong natural factors such as wind. External interference may cause the connection between the clamp and the conductor to loosen or even fall off, posing a potential safety risk to the personnel performing maintenance work.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a grounding device, comprising: a grip rod 1; an adjusting screw 8 rotatably disposed inside the grip rod 1; an adjusting support column 2 threadedly connected to the outside of the adjusting screw 8, the adjusting support column 2 being slidably connected to the grip rod 1; a fixed support plate 7 slidably disposed outside the adjusting support column 2, the bottom of the fixed support plate 7 being fixedly connected to the grip rod 1; a copper sliding seat 3 fixedly connected to the top of the adjusting support column 2, the top of the copper sliding seat 3 being fixedly connected to a first copper wire clamp 4; a copper bracket 5 fixedly connected to the top of the fixed support plate 7, the copper sliding seat 3 being slidably connected to the copper bracket 5; a second copper wire clamp 6 fixedly connected to the inside of the copper bracket 5, the second copper wire clamp 6 cooperating with the first copper wire clamp 4; and a placement assembly disposed outside the grip rod 1, the placement assembly including a support column 16 disposed outside the grip rod 1, one end of the support column 16 being fitted with a limit plate 18.
[0027] Understandably, when grounding is required for transmission line maintenance, this utility model involves inserting the grounding plug 13 at one end of the grounding wire 12 into the ground. Grounding is achieved through the grounding plug 13, the grounding wire 12, and the copper side plate 11. The second copper wire clamp 6 and the copper bracket 5 are then attached to the transmission line requiring maintenance. By rotating the insulating screw block 10, the rotating rod 9 and the adjusting screw 8 are adjusted. The adjusting screw 8, in turn, adjusts the height of the outer adjusting support 2. The adjusting support 2 moves the copper sliding seat 3 and the first copper wire clamp 4, thus moving the first copper wire clamp 4 and the second copper wire clamp 6. The spacing between the clamps 6 is adjusted. The cable is clamped by the No. 1 copper wire clamp 4 and the No. 2 copper wire clamp 6 for grounding. When grounding is no longer needed after maintenance, the clamps of the No. 1 copper wire clamp 4 and the No. 2 copper wire clamp 6 are removed from the power transmission line. The grounding wire 12 is manually wound up and then placed on the outside of the support column 16. The fixing hole 19 in the limiting plate 18 is placed on the outside of the side threaded rod 17. The limiting nut 20 is threaded on the outside of the side threaded rod 17 to limit the grounding wire 12 on the outside of the support column 16. The limiting treatment is completed after winding.
[0028] Please see Figures 1 to 5 It also includes a copper side plate 11, which is fixed to the outside of the copper bracket 5. A grounding wire 12 is provided on one side of the copper side plate 11, and a grounding plug 13 is fixed to one end of the grounding wire 12.
[0029] It is understood that this utility model completes the grounding of the copper wire clamp holding the cable by setting a grounding wire 12 and a grounding plug 13 on one side of the copper side plate 11.
[0030] Please see Figures 1 to 5 A fixed side seat 14 is fixedly connected to the outer side of the grip 1, and a fixed side plate 15 is fixedly connected to one side of the fixed side seat 14. One end of the support column 16 is fixedly connected to the fixed side plate 15, and a side threaded rod 17 is fixedly connected to one end of the support column 16. A fixing hole 19 that mates with the side threaded rod 17 is opened inside the limiting plate 18, and a limiting nut 20 is threadedly connected to the outer side of the side threaded rod 17.
[0031] It is understood that the limiting plate 18 of this utility model is installed on the outside of the side threaded rod 17 through the fixing hole 19, and the limiting nut 20 is used to tighten the limiting plate 18 at the installation position at one end of the support column 16, thereby restricting the position of the grounding wire 12 that is wound and placed on the outside of the support column 16, which is convenient for storage and movement.
[0032] Please see Figures 1 to 5The grip 1 has a rotating rod 9 inside, the top of the rotating rod 9 is fixedly connected to the adjusting screw 8, the bottom of the grip 1 has an insulating screw block 10, the bottom of the rotating rod 9 is fixedly connected to the insulating screw block 10, and the grip 1 has an outer anti-slip sleeve 21 on the outside.
[0033] It is understood that this utility model uses the insulating screw block 10 to rotate and adjust the rotating rod 9. When the rotating rod 9 rotates, it drives the adjusting screw 8 at the top to rotate. The adjusting screw 8 adjusts the height position of the adjusting support 2 on the outside, thereby adjusting the height position of the copper sliding seat 3 and the first copper wire clamp 4. The position between the first copper wire clamp 4 and the second copper wire clamp 6 is adjusted to complete the grounding clamping of the cable.
[0034] Please see Figures 1 to 5 Multiple limiting slide rods 22 are symmetrically fixed to the bottom of the copper sliding seat 3, and the limiting slide rods 22 are slidably connected to the fixed support plate 7.
[0035] It is understood that when the copper sliding seat 3 moves, the bottom limiting slide rod 22 moves synchronously. The limiting slide rod 22 slides with the fixed support plate 7, thereby improving the stability of the adjustment of the copper sliding seat 3 and the No. 1 copper wire clamp 4.
[0036] Please see Figures 1 to 5 The handle 1, rotating rod 9, insulating screw block 10 and limiting slide rod 22 are all made of polyethylene.
[0037] It is understandable that this utility model uses polyethylene material for insulation.
