Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission and transformation technology, specifically to a grounding device for power transmission and transformation equipment. Background Technology
[0002] The grounding device of power transmission and transformation equipment is a crucial component of the power system. It ensures the safety of electrical equipment and personnel. The main functions of the grounding device include: protecting personal safety, stabilizing system voltage, providing reference potential, and reducing electromagnetic interference.
[0003] In the existing technology, a grounding device for high-voltage power transmission and transformation equipment, disclosed in publication number CN220895887U, is described. This technology improves and optimizes the grounding device of high-voltage power transmission and transformation equipment in the prior art by designing a limiting mechanism at the bottom of the insulating rod. This can prevent the insulating pull wire and handle from being pulled accidentally during subsequent grounding processes, thereby improving the stability of the arc-shaped clamp and the overall use of the grounding device. When the grounding device needs to be disassembled or reassembled in the future, simply pressing down the pressing plate will release the limiting mechanism on the end seat, allowing the insulating pull wire and handle to be pulled normally.
[0004] However, in the above structure, after the grounding wire is connected to the ground, it is prone to friction and aging when dragged on the ground for a long time, which can lead to wire wear and potentially cause electric shock to people who come into contact with it. Utility Model Content
[0005] The purpose of this utility model is to provide a grounding device for power transmission and transformation equipment. By using this device, the problem of grounding wires being prone to friction and aging due to prolonged dragging on the ground after being connected to the ground can be solved, leading to line wear and electric shock to personnel who come into contact with them.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a grounding device for power transmission and transformation equipment, including a telescopic rod, a support rod at the upper end of the telescopic rod, a mounting base on one side of the support rod, and a protective component for protecting the grounding wire body inside the mounting base;
[0007] The protective component includes a mounting plate A disposed at the lower end of the mounting base. Two sets of mounting plates A are provided, each with a spring A on one side and a rubber plate on the other side. One set of mounting plates A has a fixing plate A on one side. The upper end of the mounting base has a slot A, and a movable plate is slidably connected inside the slot A. A fixing plate B is disposed at the lower end of the movable plate. A connecting plate is disposed at the upper end of the fixing plate B. A spring B is disposed on the other side of the fixing plate B. A limit plate is disposed on one side of the spring B. A locking plate is disposed on the inner wall of the mounting base. A slot B is formed on the outer surface of the locking plate. A grounding wire is locked and connected inside the mounting base. The limit plate can block the rubber plate on that side.
[0008] Furthermore, a motor is provided on one side of the support rod, a take-up roller is provided on one side of the motor, and an insulating cloth bag is provided on one side of the take-up roller.
[0009] Furthermore, a locking ring is provided on one side of the support rod, and a protective pad is provided on the inner wall of the locking ring.
[0010] Furthermore, the protective pad is made of plastic, and the outer side of the grounding wire is snapped into the inner side of the protective pad.
[0011] Furthermore, a mounting plate B is provided at the lower end of the engagement ring, and two sets of mounting plates B are provided.
[0012] Furthermore, a spring C is provided on one side of each of the two sets of mounting plates B, and a fixing plate C is provided on the inner side of the spring C.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model proposes a grounding device for power transmission and transformation equipment. Through the arrangement of a telescopic rod, a movable plate, spring B, spring A, a rubber plate, a limiting plate, and a slot B, spring B is compressed, pressing against spring A on the side without spring B. The rubber plate moves outward, engaging the grounding wire between the two sets of rubber plates. When the grounding wire needs to be engaged, the applied compression force is released, and the movable plate moves towards the grounding wire side. The connecting plate moves inward until it aligns with the position of slot B, engaging with it. Spring B returns to its original deformation, pushing the connecting plate upward in slot B, causing the limiting plate to move upward. The limiting plate does not contact the rubber plate on that side and therefore does not obstruct it. The rubber plate engages with the grounding wire for protection. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0021] Combination Figure 1 A grounding device for power transmission and transformation equipment includes a telescopic rod 1, a support rod 11 at the upper end of the telescopic rod 1, a mounting base 5 on one side of the support rod 11, and a protective component 6 for protecting the grounding wire body inside the mounting base 5.
[0022] The present invention will be further described below with reference to the embodiments.
[0023] Example 1:
[0024] Please see Figure 1 and Figure 3The protective component 6 includes a mounting plate A65 disposed at the lower end of the mounting base 5. The mounting plate A65 is provided in two sets. A spring A66 is provided on one side of each set of mounting plates A65. A rubber plate 67 is provided on one side of each set of mounting plates A65. A fixing plate A68 is provided on one side of one set of mounting plates A65. A slot A51 is opened at the upper end of the mounting base 5. A movable plate 61 is slidably connected inside the slot A51. A fixing plate B63 is provided at the lower end of the movable plate 61. A connecting plate 62 is provided at the upper end of the fixing plate B63. A spring B64 is provided on the other side of the fixing plate B63. A limit plate 69 is provided on one side of the spring B64. A locking plate 610 is provided on the inner wall of the mounting base 5. A slot B611 is opened on the outer surface of the locking plate 610. A grounding wire 3 is locked and connected inside the mounting base 5. The limit plate 69 can block the rubber plate 67 on that side.
[0025] Specifically, when spring B64 is in a compressed state, spring A66 on the side without spring B64 is squeezed with a tool. At this time, rubber plate 67 moves outward, which can engage the grounding wire 3 between the two sets of rubber plates 67. When it is necessary to engage the grounding wire 3, the applied squeezing force is released, and the moving plate 61 is moved towards the grounding wire 3 side, so that the connecting plate 62 moves inward until the position of the connecting plate 62 corresponds to the position of the slot B611. At this time, the connecting plate 62 engages with the slot B611. At this time, spring B64 returns to its deformation, thereby pushing the connecting plate 62 to move upward in the slot B611, thereby driving the limiting plate 69 to move upward. At this time, the limiting plate 69 does not contact the rubber plate 67 on this side and will not block the rubber plate 67. Thus, the rubber plate 67 engages with the grounding wire 3, which can engage the grounding wire 3 for protection.
[0026] Example 2:
[0027] Please see Figures 1-3 A motor 2 is installed on one side of the support rod 11, a winding roller 21 is installed on one side of the motor 2, an insulating cloth bag 22 is installed on one side of the winding roller 21, a locking ring 4 is installed on one side of the support rod 11, a protective pad 41 is installed on the inner wall of the locking ring 4, the protective pad 41 is made of plastic, the outer side of the grounding wire 3 is locked and connected to the inside of the protective pad 41, a mounting plate B43 is installed at the lower end of the locking ring 4, two sets of mounting plates B43 are provided, a spring C42 is provided on one side of the two sets of mounting plates B43, and a fixing plate C44 is provided on the inner side of the spring C42.
[0028] Specifically, the telescopic rod 1 can extend and retract to adjust the height of the grounding device, which can be adjusted according to actual needs. The motor 2 drives the winding roller 21 to rotate, thereby winding up the insulating bag 22. The insulation height can be adjusted according to the extension and retraction height of the telescopic rod 1 to provide insulation protection and reduce the possibility of electric shock during operation. The protective pad 41 can protect the grounding wire 3 and reduce the wear of the grounding wire 3. Using a tool to squeeze the spring C42, the grounding wire 3 can be locked between the two sets of fixing plates C44. At this time, when the spring C42 is squeezed, the spring C42 returns to its deformation, and the fixing plate C44 can contact the grounding wire 3 to lock. The protective pad 41 made of plastic has an insulating effect, which can protect the grounding wire 3 and provide insulation.
