Description

Technical Field

[0001] This utility model relates to the field of power auxiliary device technology, and in particular to a telescopic grounding device. Background Technology

[0002] The power system consists of generation, transmission, transformation, distribution, and consumption. It converts primary energy into electricity through mechanical devices, and then supplies the electricity to users through transmission, transformation, and distribution. The grounding wire is a safe return line that directly connects to the earth. In case of danger, it transfers high voltage directly to the ground. It is an important tool to ensure the safety of workers, especially when voltage is accidentally generated on de-energized equipment and lines (such as reverse power transmission) or when the circuit is accidentally closed. However, due to the variety of regional environments and conditions, and the fact that the grounding wire is also an essential tool for transmission line operations, it is very inconvenient to use general grounding insulating rods in actual power production, maintenance, and repair work in special terrains such as high mountains and ravines, special seasons such as hot summers and cold winters, and special tower types with large bends. For example, when suspending grounding wires at voltage levels of 110kV and above, conventional multi-section grounding rods are required. The length of conventional grounding rods is fixed and cannot be adjusted, making the operation time-consuming, labor-intensive, and very inconvenient.

[0003] Currently, commonly used telescopic grounding rods can only be adjusted in stages, and cannot be adjusted steplessly, thus their applicability to power maintenance sites is poor. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention, which provides a telescopic grounding device that helps workers connect a grounding wire to a distant cable crossarm. It includes a gripping component 1, the section of the structure closest to the worker's hand, primarily serving a connecting and supporting function. The gripping component 11 includes an insulated handle 11, the part the worker holds during wiring. The handle 11 needs to be insulated from the grounding wire to protect the worker, or an insulating rubber layer can be fitted over the bottom gripping section of the grounding device for insulation. A threaded rod 12 is rotatably connected to the insulated handle 11. A motor can be mounted on the insulated handle 11, and the motor's output end can be connected to the threaded rod 12, allowing the motor to drive the threaded rod 12 to rotate. The outer wall of the threaded rod 12 has threaded grooves.

[0028] The lifting member 2, disposed on the outer wall of the threaded rod 12, includes a lifting cylinder 21 sleeved on the outer wall of the threaded rod 12. The lifting cylinder 21 is sleeved on the threaded rod 12 and can slide relative to the threaded rod 12, including sliding along the central axis of the threaded rod 12 and rotating about the threaded rod 12. A retainer 22 is disposed on the outer wall of the lifting cylinder 21. When the device needs to be extended to connect to a distant cable crossarm, the retainer 22 restricts the relative rotation between the lifting cylinder 21 and the threaded rod 12. The lifting cylinder 21 can only slide relative to the threaded rod 12 along the axis of the threaded rod 12.

[0029] The wiring clamp 3 is installed on the top of the lifting component 2. The wiring clamp 3 fixes the grounding wire. When the lifting cylinder 21 slides along the axis of the threaded rod 12, the wiring clamp 3 will slide together with the lifting cylinder 21 to connect the grounding wire to the cable to be grounded at a distance. The bottom end of the grounding wire is grounded, thus completing the grounding work.

[0030] Usage: When it is necessary to ground a cable at a distance, fix the grounding wire to the clamp 3, rotate the threaded rod 12, and the lifting cylinder 21 will slide along the axis of the threaded rod 12 under the action of the threaded rod 12, away from the insulating handle 11. The lifting cylinder 21, with the clamp 3 and the grounding wire on the clamp 3, will come to the cable to be grounded. Use the clamp 3 to fix the grounding wire to the cable crossarm, thus completing the grounding work. When it is necessary to retract the grounding device, rotate the threaded rod 12 in the opposite direction, and the lifting cylinder 21 will slide towards the insulating handle 11 under the action of the threaded rod 12, thus completing the retraction of the telescopic grounding device.

[0031] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, the outer wall of the lifting cylinder 21 is provided with a sliding groove 211, and the edge of the sliding groove 211 is provided with a retaining edge 212. The inner wall of the lifting cylinder 21 is provided with a locking block 213. The locking block 213 cooperates with the threaded groove on the surface of the threaded rod 12. The end of the locking block 213 away from the lifting cylinder 21 is embedded in the threaded groove. When the relative rotation between the lifting cylinder 21 and the threaded rod 12 is restricted by the retainer 22, the rotation of the threaded rod 12 will apply a force in the axial direction of the threaded rod 12 to the locking block 213, thereby causing the lifting cylinder 21 to slide along the direction of the threaded rod 12. This allows the lifting cylinder 21, carrying the wiring clamp 3, to move away from the insulating handle 11 to the distant grounding cable or to retract close to the insulating handle 11, thus shortening the size of the entire device and making it easier to carry and store.

[0032] Furthermore, the retainer 22 includes a connecting rod 222, the bottom of which is connected to the insulating handle 11, and a slider 221 is provided at the top of the connecting rod 222. The slider 221 is fixedly connected to the connecting rod 222 and is located inside the slide groove 211. The slider 221 can slide inside the slide groove 211, and relative sliding can occur between the retainer 22 and the lifting cylinder 21. When the bottom of the connecting rod 222 is fixedly connected to the top of the insulating handle 11, when the threaded rod 12 rotates on the insulating handle 11, the lifting cylinder 21, which is sleeved outside the insulating handle 11, is restricted by the connecting rod 222 and cannot rotate relative to the threaded rod 12. Therefore, under the action of the threaded rod 12, the lifting cylinder 21 can only slide towards or away from the insulating handle 11.

[0033] Furthermore, the wiring clamp 3 includes a hook 31 disposed on the top of the lifting cylinder 21. A baffle 32 is provided at the opening of the hook 31. Preferably, the baffle 32 can be hinged to the hook 31. A torsion spring can be provided at the connection between the baffle 32 and the hook 31. In this way, the grounding wire can be clamped between the baffle 32 and the hook 31, or the grounding wire can be fixed to the hook 31 by winding or welding. When the telescopic device sends the hook 31 to the cable to be grounded, the grounding wire can be connected to the cable to be grounded by directly hooking the hook 31 onto the crossarm of the cable to be grounded, thus completing the grounding work.

[0034] Furthermore, a lever 223 is provided on the side of the connecting rod 222, and a protrusion 224 is provided on the bottom of the connecting rod 222, protruding on the connecting rod 222 towards the axis of the threaded rod 12. A frustum 121 is provided at the bottom of the threaded rod 122, and a first bevel gear 123 is provided at the bottom of the frustum 121. A crank 111 is provided on the top of the insulating handle 11, and the crank 111 is rotatably connected to the insulating handle 11. Preferably, the crank 111 is also insulated, and a second bevel gear is provided on the side of the crank 111. Gear 112, the second bevel gear 112 meshes with the first bevel gear 123, and the top of the insulating handle 11 is provided with a receiving groove 113 on the side away from the crank handle 111. The outer wall of the receiving groove 113 is provided with a pin 114. When it is necessary to use the rotating threaded rod 12 to raise and lower the lifting cylinder 21, hold the lever 223 and pull the connecting rod 222 down to pull the protrusion 224 into the receiving groove 113. Insert the pin 114 to lock the protrusion 224. At this time, the connecting rod 222 and the insulating handle 11 are fixed together.

[0035] Usage: When grounding, hold the insulating handle 11 with one hand and the lever 223 with the other hand to pull the connecting rod 222 downwards, pulling the protrusion 224 into the receiving groove 113. Insert the pin 114 to lock the protrusion 224. At this time, the connecting rod 222 and the insulating handle 11 are fixed together. Then turn the rocker handle 111 to make the second bevel gear 112 rotate, which drives the first bevel gear 123 to rotate. The first bevel gear 123 will rotate along with the threaded rod 12, thereby driving the lifting cylinder 21 to rise and fall, completing the extension and retraction of the grounding device.

[0036] Example 3, referring to Figures 1-4 This is the third embodiment of the present invention. Unlike the previous embodiment, in actual inspection or maintenance work, sometimes when encountering windy weather or when multiple grounding wires need to be connected, it is necessary to use a grounding device to fix the grounding wire to a cable crossarm at a distance. It is necessary to twist the grounding wire to the crossarm by using a telescopic grounding rod. This requires the workers to rotate the grounding rod continuously, which is labor-intensive. In a better way, the bottom edge of the truncated cone 121 of this device is provided with a slot 122. The slot 122 cooperates with the protrusion 224. When the protrusion 224 of the connecting rod 222 is engaged in the slot 122 at the bottom of the truncated cone 121, the connecting rod 222 can be fixedly connected to the truncated cone 121.

[0037] Usage: When it is necessary to use the grounding device to twist and wrap the ground wire around the cable crossarm, simply use the lever 223 to push the connecting rod 222 upward, so that the protrusion 224 engages with the slot 122 of the truncated cone 121. At this time, when the second bevel gear 112 is rotated to drive the threaded rod 12 to rotate together, the threaded rod 12 will drive the truncated cone 121 and the connecting rod 222 on the side of the truncated cone 121 to rotate together, which can drive the lifting cylinder 21 to rotate together, thereby driving the grounding wire to twist and wrap around the crossarm, reducing the labor intensity of the workers.
