Description

Technical Field

[0001] This invention relates to tools for power transmission line maintenance, and more specifically, to a conductor grounding device with a cyclic opening and closing function. Background Technology

[0002] During power outage maintenance of transmission lines, the grounding wire is the most important safety measure. Hanging and removing the grounding wire is a necessary task every time. Currently, the grounding wire is hung and removed using two insulated ropes. The two insulated ropes are connected in parallel between the grounding end and the conductor end of the grounding wire. Due to the winding and storage of the grounding wire, the insulated ropes often get tangled and knotted with the grounding copper wire, which seriously affects the smooth hanging and removal of the grounding wire. This not only wastes working time but also greatly consumes the physical strength of the workers, and poses many inconveniences and safety hazards.

[0003] Most existing grounding wire sets in China use spring clips, and the insulated ropes for hanging and removing them are purchased and installed by the user. Generally, there are two insulated ropes, one for hanging and one for removing, which are very easy to get tangled and knotted with the grounding wire. At present, there is no good solution.

[0004] Therefore, how to achieve rapid installation of grounding devices and design a grounding device that can accommodate cables of different diameters has become a technical bottleneck that urgently needs to be overcome in the field of power transmission line maintenance. Summary of the Invention

[0005] To overcome the above problems, this invention redesigns the grounding device at the grounding wire end, enabling it to achieve cyclic opening and closing using only a single insulating rope. Existing wire grounding devices are mostly spring-loaded and fixed. If the wire size is large, the spring compression pressure is high, making it difficult to hang and remove. If the wire size is small, the spring compression is insufficient, resulting in inadequate contact area and gripping force. This device also avoids the problem of multiple simultaneous winding and knotting of two insulating ropes and the grounding copper wire.

[0006] The purpose of this invention is to provide a conductor grounding device with a cyclic opening and closing function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conductor grounding device with a cyclic opening and closing function, comprising a main body, wherein a receiving cavity is provided inside the main body, a triggering mechanism is installed at the bottom of the receiving cavity, and two connecting posts are symmetrically arranged above the triggering mechanism inside the receiving cavity, and grounding claws are rotatably installed on the outer side of the two connecting posts. The triggering mechanism is used to drive the two grounding claws to move closer to each other, and the two grounding claws grip the cable during the process of moving closer to each other. An internal retraction component is also provided inside the grounding claw away from the triggering mechanism. The internal retraction component is used to adjust the gripping diameter of the grounding claw. The internal retraction component specifically includes an internal retraction part and a release part. The internal retraction part is installed on the inner ring surface of the grounding claw, and the release part is installed on the end of the grounding claw away from the triggering mechanism. Furthermore, when the two grounding claws come together and are completely closed, the two release parts come into contact with each other, extending the inner retracted parts inside the two grounding claws, which then grip the cable.

[0008] Furthermore, the triggering mechanism specifically includes two side plates, a triggering cavity, and a triggering block. The triggering cavity is located at the bottom of the receiving cavity, the two side plates are installed on the upper sides of the triggering cavity, and the triggering block is slidably installed between the two side plates. Two spring pieces are also cross-installed at the top of the triggering block, and the ends of the two spring pieces are cross-connected to the outer side of their respective grounding claws. Switching slots are provided on both sides of the trigger block. Inside the trigger cavity, on both sides below the trigger block, there are also mounting brackets. A linkage rod is inserted into the mounting bracket. One end of a lever is installed on both sides of the linkage rod, and a switching post is installed on the other end of the two levers. The switching post is inserted into the switching slot.

[0009] Furthermore, a pull groove is provided inside the main body, and the two ends of the pull groove are located in the trigger cavity and the top of the main body, respectively. One end of the insulating rope is connected to the bottom of the trigger block, and the other end of the insulating rope extends to the outside of the main body through the pull groove. The individual side plate is also provided with a moving groove. One end of the second push-out spring is installed at the bottom of the moving groove. Moving blocks are provided on both sides of the trigger block to cooperate with the moving groove, and the other end of the second push-out spring is connected to the bottom of the moving block.

[0010] Furthermore, hook areas are provided at both the upper and lower ends of the switching slot, and the switching column switches within the two hook areas when the insulating rope pulls the trigger block down.

[0011] Furthermore, the inner section specifically includes a retrieval cavity opened inside the grounding claw, a first push-out spring installed inside the retrieval cavity, and an inner claw. There are multiple first push-out springs, the inner claw is embedded in the retrieval cavity, and the ends of the multiple first push-out springs are connected to the outer ring surface of the inner claw. The grounding claw has a stabilizing groove inside the recovery chamber, and a stabilizing block is set on the outside of the stabilizing groove to match the stabilizing claw.

[0012] Furthermore, the release part specifically includes a plug hole opened at the end of the grounding claw, and a through overlapping hole is also provided inside the plug hole near the side of the inner claw. A stop member is provided at the end of the inner claw corresponding to the position of the overlapping hole, and the end of the stop member abuts against the overlapping hole. A spring cavity is provided in the middle section of the insertion hole. A third push-out spring is provided inside the spring cavity. A contact pin is also inserted inside the third push-out spring. An extruded round head is installed at the end of the contact pin. The other end of the contact pin extends to the outside of the insertion hole. After the two grounding claws are fully closed, the two contact pins outside the insertion hole press against each other, and their respective extrusion heads press down to squeeze the abutment out of the overlapping hole.

[0013] Furthermore, an actuating plate is installed on the outer ring surface of the contact pin, and the actuating plate is slidably installed inside the spring cavity.

[0014] Furthermore, the abutting component specifically includes a groove formed on the side of the inner claw, one end of a fourth abutting spring is connected inside the groove, the other end of the fourth abutting spring is connected to a slider, and an abutting round head is installed at the end of the slider. Furthermore, when the slider is inserted into the overlapping hole, the abutting round head is located below the extrusion round head.

[0015] Furthermore, a grounding wire is connected to the side of the main body, and the grounding wire is connected to the grounding claw and the inner retractor.

[0016] Furthermore, a roller is installed inside the trigger chamber, and an insulating rope is attached to the outside of the roller.

[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages: 1. This invention, by setting up a triggering mechanism, grounding claws, a main body, and an insulating rope, connects the grounding wire to the main body. The working mechanism is driven by the pulling of the insulating rope, which in turn drives the grounding claws to rotate out of the internal storage cavity of the main body. This completes the closing and closing of the two grounding claws and the gripping of the cable, effectively reducing the tangling and knotting of the grounding wire and greatly increasing the efficiency of power transmission line maintenance.

[0018] 2. This invention incorporates an internal retractable component within the grounding claw. This component comprises a retractable portion and a release portion. When not triggered, the retractable component is housed within the grounding claw. Only when the two grounding claws are fully closed do the two contact pins, located outside the insertion hole, press against each other, and their respective extrusion heads push the contact component out of the overlapping hole, releasing the fixation of the retractable portion. This allows the retractable portion to stably extend from within the grounding claw, thus adapting to gripping and mounting small-diameter cables. This ensures that the cable does not wobble between the two grounding claws, maintaining the maximum contact area between the device and the cable at all times, thereby improving safety and applicability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0022] Please see Figures 1 to 8 In one embodiment of this application, a wire grounding device with a cyclic opening and closing function includes a main body 1. The main body 1 has a housing cavity 2 inside. A triggering mechanism is installed at the bottom of the housing cavity 2. Two connecting posts 14 are symmetrically arranged at the upper end of the triggering mechanism inside the housing cavity 2. Grounding claws 6 are rotatably installed on the outer side of the two connecting posts 14. The triggering mechanism is used to drive the two grounding claws 6 to move closer to each other, and the two grounding claws 6 grasp the cable during the process of moving closer to each other. The individual grounding claw 6 is also provided with an inner retracting part inside the triggering mechanism. The inner retracting part is used to adjust the gripping diameter of the grounding claw 6. The inner retracting part specifically includes an inner retracting part and a release part 5. The inner retracting part is installed on the inner ring surface of the grounding claw 6, and the release part 5 is installed on the end of the grounding claw 6 away from the triggering mechanism. Furthermore, when the two grounding claws 6 come together and are completely closed, the two release parts 5 come into contact with each other, and the inner retracted parts inside the two grounding claws 6 extend out, and the two inner retracted parts grip the cable.

[0023] Furthermore, a grounding wire 3 is also connected to the side of the main body 1, and the grounding wire 3 is connected to the grounding claw 6 and the inner retractor.

[0024] This embodiment is implemented as follows: First, a storage cavity 2 is opened inside the main body 1, and the triggering mechanism and two grounding claws 6 are installed in the storage cavity 2. When mounting, the main body 1 is lowered through the grounding wire 3. After the cable is lowered, the main body 1 is pulled upward through the grounding wire 3 and the insulating rope 4, so that the main body 1 is snapped onto the outside of the cable. When the insulating rope 4 is pulled, the triggering mechanism is driven to work. When the triggering mechanism works, the two grounding claws 6 rotate out from inside the storage cavity 2 and come together to grasp the outside of the cable.

[0025] Furthermore, to prevent the two grounding claws 6 from being too large in diameter and unable to firmly grip the cable, an inner retraction component is also provided inside the grounding claws 6. The inner retraction component can only be triggered when the two grounding claws 6 are fully closed. In other words, when the grounding claws 6 grip a cable with a larger diameter, the two grounding claws 6 can be fastened to the outside of the cable. At this time, the grounding claws 6 and the cable are firmly fixed and will not loosen. When the cable diameter is small, the two grounding claws 6 can close easily. This means that the grounding claws 6 are in a wobbly state after closing. Therefore, the inner retraction component is set to work at this time to ensure that the inner retraction component can tighten and grip the outside of the cable again, so that the grounding claws 6 will not wobble.

[0026] Please see Figures 1 to 8 As a preferred embodiment of this application, the triggering mechanism specifically includes two side plates 19, a trigger cavity 12, and a trigger block 10. The trigger cavity 12 is opened at the bottom of the receiving cavity 2. The two side plates 19 are installed on the upper sides of the trigger cavity 12, and the trigger block 10 is slidably installed between the two side plates 19. Two spring members 15 are also cross-installed at the top of the trigger block 10, and the ends of the two spring members 15 are cross-connected to the outer side of their respective distant grounding claws 6. Both sides of the trigger block 10 are provided with switching slots 26. Inside the trigger cavity 12, on both sides below the trigger block 10, there are also mounting brackets 22. A linkage rod 21 is inserted into the mounting bracket 22. One end of a lever 17 is installed on both sides of the linkage rod 21, and the other end of the two levers 17 is installed with a switching post 25, which is inserted into the switching slot 26.

[0027] Furthermore, a pull groove 24 is provided inside the main body 1, and the two ends of the pull groove 24 are located in the trigger cavity 12 and the top of the main body 1, respectively. One end of the insulating rope 4 is connected below the trigger block 10, and the other end of the insulating rope 4 extends to the outside of the main body 1 through the pull groove 24. The individual side plate 19 is also provided with a moving groove 18. One end of the second push-out spring 20 is installed at the bottom of the moving groove 18. Moving blocks 16 are provided on both sides of the trigger block 10 in coordination with the moving groove 18, and the other end of the second push-out spring 20 is connected to the bottom of the moving block 16.

[0028] Furthermore, the upper and lower ends of the switching slot 26 are provided with hook areas, and when the insulating rope 4 pulls the trigger block 10 down, the switching column 25 switches within the two hook areas.

[0029] Furthermore, the bottom of the protective cover is symmetrically provided with splicing interfaces below the extension opening, and the inside of the protective cover is symmetrically provided with an inner ring groove on the inner ring surface of the extension opening. The top of the protective cover is symmetrically provided with splicing blocks, and the splicing blocks are inserted through the splicing interfaces and rotated into the inner ring groove.

[0030] Furthermore, a roller 23 is also provided inside the trigger cavity 12, and the insulating rope 4 is attached to the outside of the roller 23.

[0031] This embodiment is implemented as follows: As mentioned above, the purpose of setting the trigger mechanism is to control the rotation operation of the two grounding claws 6, thereby achieving the gripping effect of the grounding claws 6. Specifically, a trigger cavity 12 and a trigger block 10 are set at the bottom of the storage cavity. The trigger block 10 can slide up and down inside the trigger cavity 12, and moving blocks 16 are set on both sides of the trigger block 10 to slide in conjunction with the moving grooves 18 on both sides inside the trigger cavity 12. A second push-out spring 20 is set inside the moving groove 18. The second push-out spring 20 will push up the moving block 16 at all times so that the trigger block 10 keeps moving upward.

[0032] During operation, the trigger block 10 is pulled down by the insulating rope 4. The trigger block 10 is forced to retract the second push-out spring 20. At the same time, when the trigger block 10 moves down, the switching post 25 moves inside the switching grooves 26 on both sides of the trigger block 10. The movement of the switching post 25 depends on the setting of the lever 17 and the linkage rod 21 to ensure the stable movement of the switching post 25. The movement of the switching post 25 has only two positions, namely the upper and lower hook areas inside the trigger groove. This controls the trigger block 10 to be positioned once after moving up or down, ensuring that the position of the two grounding claws 6 after they come together is fixed.

[0033] During the up-and-down movement of the trigger block 10, it pulls the spring component 15. The two spring components 15 pull each other to automatically move their respective grounding claws 6 away from each other, thus realizing the gripping of the two grounding claws 6.

[0034] Meanwhile, in order to facilitate pulling the insulating rope 4, a roller 23 is also installed inside the trigger cavity 12 to ensure the stable pulling of the insulating rope 4.

[0035] Furthermore, to prevent the displacement of the toggle levers and switching posts 25 on both sides from being inconsistent when the trigger block 10 moves down, a mounting bracket 22 and a linkage rod 21 are also provided to ensure that when the toggle lever on one side rotates, the toggle lever on the other side will move synchronously, thus ensuring that the trigger block 10 moves synchronously on both sides and moves down stably.

[0036] Please see Figures 1 to 8 As a preferred embodiment of this application, the inner portion specifically includes a recovery cavity 13 opened inside the grounding claw 6, a first push-out spring 7 installed inside the recovery cavity 13, and an inner claw 11. There are multiple first push-out springs 7, the inner claw 11 is embedded in the recovery cavity 13, and the ends of the multiple first push-out springs 7 are connected to the outer ring surface of the inner claw 11. The grounding claw 6 has a stabilizing groove 9 located on the side of the recycling chamber 13, and a stabilizing block 8 is provided on the outside of the inner claw 11 in conjunction with the stabilizing groove 9.

[0037] Furthermore, the release part 5 specifically includes a plug hole 27 opened at the end of the grounding claw 6. The plug hole 27 is also provided with a through overlapping hole 36 on the side near the inner claw 11. The end of the inner claw 11 is provided with an abutment at the position corresponding to the overlapping hole 36, and the end of the abutment abuts against the overlapping hole 36. A spring cavity is provided in the middle section of the insertion hole 27. A third push-out spring 30 is provided inside the spring cavity, and a contact pin 28 is also inserted inside the third push-out spring 30. An extruded round head 31 is installed at the end of the contact pin 28, and the other end of the contact pin 28 extends to the outside of the insertion hole 27. After the two grounding claws 6 are fully closed, the two contact pins 28 are pressed against each other at the part outside the insertion hole 27, and the abutment is pushed out of the overlapping hole 36 by their respective extrusion round heads 31.

[0038] Furthermore, an actuating plate 29 is mounted on the outer ring surface of the contact pin 28, and the actuating plate 29 is slidably mounted inside the spring cavity.

[0039] Furthermore, the abutting component specifically includes a groove 34 opened on the side of the inner claw 11, one end of a fourth abutting spring 35 is connected inside the groove 34, the other end of the fourth abutting spring 35 is connected to a slider 33, and an abutting round head 32 is installed at the end of the slider 33. Furthermore, when the slider 33 is inserted into the overlapping hole 36, the abutting head 32 is located below the extrusion head 31.

[0040] This embodiment is implemented as follows: As mentioned above, in order to prevent the two grounding claws 6 from easily closing when the cable diameter is small, resulting in the grounding claws 6 being in a wobbly state after closing, the inner shrinking component is triggered at this time to ensure that the inner shrinking component can firmly grip the outside of the cable again, so that the grounding claws 6 will not wobble.

[0041] Specifically, this is achieved through an inward retraction section, which consists of multiple first push-out springs 7 installed inside the recycling chamber 13, with an inner claw 11 connected to the outside of the first push-out springs 7. The inner claw 11 is pushed out by the first push-out springs 7, and a stabilizing groove 9 and a stabilizing block 8 are provided to ensure the stable push-out of the inner claw 11 without any deviation, thus achieving the function of wrapping and gripping the outside of the cable.

[0042] However, in order to ensure that the inner claw 11 only works when gripping small-diameter cables, a release part 5 is provided. The release part 5 consists of an abutment and a contact pin 28. An insertion hole 27 and a spring cavity are provided on the end faces of the two grounding claws 6 that are close to each other. The contact pin 28 is inserted into the third abutment spring 30 inside the spring cavity, and the third abutment spring 30 is contracted by the actuating plate 29, which realizes the extension and retraction of the contact pin 28. The two grounding claws 6 come together and close, which drives the two contact pins 28 to come together and close. At the same time, the two contact pins 28 will drive their respective extrusion round heads 31 to squeeze the abutment. The abutment is provided by the slide groove 34 and the slider 33. The slider 33 is installed in the slide groove 34 by the fourth abutment spring 35. In the connected state, the slider 33 is inserted into the overlapping hole 36. At this time, the abutment round head 32 is inside the insertion hole 27 and below the extrusion round head 31. When the extrusion round head 31 is pressed downward, the abutment round head 32 is extruded. Similarly, the slider 33 will retract by the fourth extrusion spring and leave the overlapping hole 36. At this time, the inner claw 11 is released from the fixation. Multiple first abutment springs 7 push out the inner claw 11 to achieve gripping and fixing of small diameter cables.

[0043] In summary, this invention, by setting up a triggering mechanism, grounding claws 6, a main body 1, and an insulating rope 4, connects the grounding wire 3 to the main body 1. The insulating rope 4 pulls the triggering mechanism, which in turn drives the grounding claws 6 to rotate out of the receiving cavity 2 inside the main body 1, completing the closing and clamping of the two grounding claws 6 and the gripping of the cable. This effectively reduces the tangling and knotting of the grounding wire 3, significantly increasing the efficiency of power transmission line maintenance. Furthermore, by incorporating an internal retractable component inside the grounding claws 6, consisting of a retracting part and a releasing part 5, the retracting... When not triggered, the component is stored in the grounding claw 6. Only when the two grounding claws 6 are fully closed, the two contact pins 28 on the outside of the insertion hole 27 press against each other, and the extrusion head 31 of each pin presses down to push the abutment component out of the overlapping hole 36, releasing the fixation of the inner part, so that the inner part can stably extend out of the grounding claw 6. This is to accommodate small-diameter cables for gripping and mounting, ensuring that the cable will not shake between the two grounding claws 6, and ensuring that the contact area between the device and the cable is always at its maximum, thus improving safety and applicability.
