Description

Technical Field

[0001] This utility model relates to the field of power system tool technology, specifically to a pole detachable grounding pole. Background Technology

[0002] Grounding sealing in substations is an essential and crucial step in ensuring the safety of personnel and equipment. Grounding rods are an important tool in this process. A grounding rod is a standardized term for a set of insulating tools specifically used in power systems, employed during power outages to ensure the safety of personnel. A grounding rod mainly consists of a clamp end, a rod body, and a grounding end. For example, the portable high-voltage grounding rod disclosed in CN 211829255 U, when in use, has its clamp end holding the power line, grounded through a grounding wire. During use, the grounding rod is always suspended above the power line. A large number of grounding rods are required, and their testing cycle is typically six months, a relatively long period. They are also highly susceptible to environmental factors; exposure to sunlight or rain will reduce their insulation strength. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a detachable grounding pole that can be separated from the clamp after the conductor is held in place. One pole can be used for multiple clamps, effectively reducing the number of poles required. Furthermore, during the testing period, the pole is protected from the influence of the natural environment, ensuring its insulation performance.

[0004] Specifically, this utility model is implemented as follows:

[0005] A detachable grounding pole includes a clamp and an insulated pole body. A connector is provided on the outside of the clamp, and a hook is provided on the top of the pole body. The connector and the hook form a detachable structure. In use, the hook is connected to the connector to clamp the clamp onto the power line.

[0006] Furthermore, the hook portion is L-shaped.

[0007] Furthermore, the connector is arranged vertically, and its overall structure is a U-shaped ring.

[0008] Furthermore, a ball head is provided at the end of the hook that is away from the shaft;

[0009] The side of the connector that is connected to the clamp is called the connecting side, and the side away from the clamp is called the away side. The distance between the connecting side and the away side is less than the diameter of the ball head.

[0010] The far side is provided with a protrusion so that a channel for the ball head to enter and exit is formed between the connecting side and the protrusion.

[0011] Furthermore, a grounding part is provided at the bottom of the clamp, which is used to connect a grounding wire.

[0012] The working principle of this utility model:

[0013] In use, first connect the grounding part at the bottom of the clamp to the grounding wire with a bolt. Then, insert the hook of the rod into the protrusion of the connector to hook the connector. Then, lift the rod to move the hook to the top of the connector. At this time, due to the limiting effect of the ball head, the hook cannot be dislodged from the connector. Then, lift the rod again, and after the clamp holds the wire, lower the rod to move the ball head to the channel at the protrusion position. Then, remove the connector from the channel to complete the installation of a single clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) The pole separation and unhooking grounding pole provided by this utility model can effectively reduce the reserve of grounding pole body in substation, avoid the influence of environmental factors on its insulation performance under long test cycle, and improve the service life of the pole body.

[0016] (2) The hook adopts a ball head design and is equipped with a U-shaped connector with a protrusion, which can effectively prevent the hook from coming out of the connector during use and improve the safety during use. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, this embodiment provides a detachable grounding pole, including a clamp 1 and an insulated pole body 2. The inner side of the clamp 1 is a clamping structure, mainly composed of two arc-shaped pieces forming a "V" shape. When moving from top to bottom, the conductor 4 enters the clamping structure from the bottom and is clamped by the pressure of the two arc-shaped pieces. At the same time, under the action of gravity, it can effectively prevent the wire from coming loose. Figure 2 As shown, a U-shaped ring-shaped connector 11 is installed on the outside of the clamp 1. The side of the connector 11 that connects to the clamp 1 is the connecting side 13, and the side away from the clamp 1 is the away side 14. The connecting side 13 is fixed to the outside of the clamp 1 by bolts. The bottom of the clamp 1 is a grounding part 12, which is connected to the grounding wire 3 by bolts. The conductor 4 can be grounded through the clamp 1 and the grounding wire 3.

[0027] like Figure 3 As shown, the shaft 2 is made of insulating material and has a hook 21 at the top. The hook 21 is L-shaped and has a ball head 22 at the end. The hook 21 can extend into the connector 11, and the clamp 1 can be placed and removed by supporting the connector 11. The distance between the connecting side 13 and the far side 14 of the connector 11 is smaller than the diameter of the ball head 22. At the same time, a protrusion 15 is provided on the far side 13, and a channel for the ball head 22 to enter and exit is formed between the connecting side 13 and the protrusion 15. Figure 4 As shown, the ball head 22 of the hook 21 can only enter through this channel, which can effectively prevent the hook 21 from coming out of the connector 11 during use, thus improving safety and stability during use.

[0028] Specifically, such as Figure 5 As shown, the usage process of this detachable grounding pole is as follows:

[0029] In use, first connect the grounding part 12 at the bottom of the clamp 1 to the grounding wire 3 with a bolt. Then, insert the hook 21 of the rod body 2 through the protrusion 15 of the connector 11 to hook the connector 11. Then, lift the rod body 2 to move the hook 21 to the top of the connector 11. At this time, due to the limiting effect of the ball head 22, the hook 21 cannot be dislodged from the connector 11. Then, lift the rod body 2, and after the clamp 1 holds the wire 4, lower the rod body 2 to move the ball head 22 to the channel at the position of the protrusion 15. Then, remove the connector 11 from the channel to complete the installation of a single clamp 1. Repeat the above operation to install multiple clamps 1. Reverse the operation to remove the clamp 1 from the wire 4.

[0030] This detachable grounding rod is easy to use, effectively reducing the manpower and material resources required for testing, reducing disassembly and assembly time, and can be removed and placed indoors at any time during use, unaffected by external weather conditions, ensuring its insulation performance.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
