Description

Technical Field

[0001] This invention relates to the field of power safety technology, and in particular to a fast-locking structure for high-voltage grounding components. Background Technology

[0002] In power systems, electrical equipment may become accidentally energized due to aging, wear, or overvoltage breakdown of insulation. This can lead to damage to electrical equipment and electric shock accidents. To avoid such accidents, protective grounding measures are usually taken, which connect the normally non-energized metal parts of electrical equipment to the grounding device. High-voltage grounding wires are important equipment used in line and substation construction to prevent electrostatic induction electric shock from nearby energized bodies or accidental closing of circuits.

[0003] Currently, the conductor end connection of high-voltage grounding devices mainly adopts screw-type or spring-type clamps. However, when using traditional grounding wires, it is necessary to first test for power according to regulations, and after confirming that the power is off, first tighten the grounding wire clamp on the grounding electrode, and then hang the conductor clamp on the conductor. After the work is completed, first remove the conductor clamp, and then remove the grounding wire clamp. The operation process is very cumbersome. Some grounding clamps require operators to adjust and hold each clamp individually during use, making the overall operation cumbersome. In addition, existing grounding stakes have the problem of difficult thread engagement, which makes the installation process time-consuming and requires multiple alignments of the threads to be successfully installed, directly resulting in low construction efficiency.

[0004] Furthermore, the existing grounding stake nuts are not easy to tighten and are prone to loosening, resulting in unreliable grounding. The clamps of the all-copper alligator mouth grounding clamps are prone to loosening, leading to poor contact between the clamps and the conductors. At the same time, the clamp mechanism is not firm and is prone to falling off due to wind or swinging, which seriously affects the stability and safety of the grounding connection.

[0005] The existing grounding device's clamping components lack a reliable positioning and guiding mechanism, making it easy for the clamping position to shift during operation, which affects the clamping effect. At the same time, the clamping force adjustment lacks a precise transmission mechanism, making it difficult to ensure a stable and uniform clamping force. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a quick-engaging and fastening structure for high-voltage grounding components, which involves fewer operation steps and is less difficult, effectively reducing the labor intensity of high-altitude operations.

[0007] The technical solution of the present invention to achieve the above objectives is as follows: a fast-locking structure for a high-voltage grounding component, comprising a base plate, characterized in that fixing holes are respectively opened at both ends of the base plate, a threaded sleeve is fixedly installed at the center of the lower side of the base plate, a conductive cone is internally threaded into the threaded sleeve, magnetic frames are fixedly installed on both sides of the threaded sleeve on the lower side of the base plate, a magnetic retainer is movably embedded in each magnetic frame, and a cable connector is fixedly installed at the center of the upper side of the base plate;

[0008] The cable connector includes a fixed frame, which is fixedly installed on the upper center of the base plate. A groove is provided on the upper wall of the fixed frame. A first magnetic block is fixedly embedded in the center of the groove. A sliding mount is movably embedded in the groove. A clamp is fixedly installed at the top of the sliding mount.

[0009] Preferably, the sliding mounter includes a sliding block, the lower end of which is movably embedded in the sliding groove, a second magnetic block is fixedly embedded at the center of the lower wall of the sliding block, the second magnetic block is in contact with the first magnetic block, a connecting block is fixedly installed at the top of the sliding block, two locators are fixedly installed on both sides of the connecting block, and two positioning holes are opened at the center of both sides of the fixing frame.

[0010] Preferably, each of the positioners includes a hinge seat, which is fixedly installed at the center of the side wall of the connecting block. A positioning plate is hinged to the hinge seat through a shaft. A positioning block is fixedly installed on one side of the lower end of the positioning plate. One end of the positioning block is movably embedded in the positioning hole. An mounting plate is fixedly installed on the lower end of the hinge seat. A spring is connected between the bottom end of the mounting plate and the positioning plate.

[0011] Preferably, the clamp includes a clamping frame, which is fixedly installed on the top of the connecting block. The clamping frame has operating grooves at both ends of its side wall. A lower pressure plate is movably embedded in the operating groove. An installation rod is vertically installed on the outer side of the lower pressure plate. A rack is fixedly installed on the outer wall of the installation rod. A driver is fixedly installed at the lower end of the center of the outer wall of the clamping frame. The driver meshes with the rack.

[0012] Preferably, the driver includes a mounting bracket, which is fixedly mounted on the lower end of the center of the outer wall of the clamping frame. The mounting bracket is movably fitted onto the outside of the rack. A worm gear is movably mounted inside the mounting bracket via a bearing. One side of the worm gear meshes with the rack. An operating nut is fixedly mounted on the top end of the worm gear.

[0013] Preferably, each of the magnetic frames includes a mounting frame, which is fixedly mounted on one side of the lower end of the base plate. A third magnetic block is fixedly mounted at the center of the mounting frame, and the top of the magnetic retainer is movably embedded in the mounting frame and fits against the bottom of the third magnetic block.

[0014] Preferably, the magnetic fastener includes a fixing plate, the top of which is movably embedded in the mounting frame, the center of the upper wall of the fixing plate is in contact with the third magnetic block, and a fourth magnetic block is fixedly installed at the center of the lower wall of the fixing plate.

[0015] Preferably, the second magnetic block has opposite magnetic poles to the first magnetic block.

[0016] Preferably, the clamping frame is a C-shaped clamping frame.

[0017] The present invention provides a high-voltage grounding component quick-locking and fastening structure. Through the magnetic frames set on both sides of the lower end of the base plate and the magnetic retainers movably embedded therein, the grounding component is quickly positioned and initially fixed by magnetic attraction. At the same time, the sliding installer is slidably embedded in the groove of the fixed frame. The first magnetic block and the second magnetic block are magnetically attached to achieve quick sliding into place. The locator is driven by a spring to automatically embed the locating block into the locating hole to achieve quick locking. The entire assembly and disassembly process is simple to operate, without the need for tedious thread alignment and repeated tightening, which significantly improves the efficiency of grounding operations.

[0018] Multiple locking mechanisms are employed to ensure connection reliability. After the sliding mount is in place, the positioning block automatically engages with the positioning hole under the action of the spring, achieving mechanical locking and preventing accidental loosening. The clamp adopts a rack and pinion meshing transmission method. The meshing of the worm and rack has self-locking characteristics, which can effectively prevent the clamping force from loosening due to vibration. The clamping force is uniform and controllable, avoiding the problem of easy loosening of traditional threaded connections and ensuring stable and reliable clamping during long-term use.

[0019] The gripper is precisely guided and slidable by the cooperation of the slide groove and the sliding block, ensuring that the gripper moves to the accurate position along the predetermined trajectory. The positioner adopts a linkage structure of hinge seat, positioning plate and spring, and automatically locks after it is in place, without the need for additional manual operation. The C-shaped clamping frame provides ample operating space, which is convenient for the insertion and removal of cables. The operator only needs to push the sliding installer to the designated position to complete the positioning and initial fixation, and then drive the worm gear by rotating the operating nut to complete the clamping. The operation steps are few and the difficulty is low, which effectively reduces the labor intensity of high-altitude operations. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, a high-voltage grounding component quick-locking fastening structure includes a base plate 1, which is elongated. Fixing holes 2 are respectively opened at both ends of the base plate 1. A threaded sleeve 3 is fixedly installed at the center of the lower side of the base plate 1. A conductive cone 4 is movably threadedly connected inside the threaded sleeve 3. Magnetic frames are fixedly installed on both sides of the threaded sleeve 3 on the lower side of the base plate 1. A magnetic retainer is movably embedded in each magnetic frame. A cable connector is fixedly installed at the center of the upper side of the base plate 1.

[0029] In use, the operator first moves the device to the designated installation location and determines the material type of the installation location based on the actual working environment, thereby selecting the appropriate grounding installation method. When the installation location is a metal floor or metal component surface, the operator must first unscrew and remove the conductive cone 4 inside the threaded sleeve 3, and then embed the magnetic retainer into the magnetic frames on both sides of the lower end of the base plate 1. The magnetic attraction force inside the magnetic frames firmly holds the magnetic retainer at the lower end of the base plate 1. Then, the magnetic surface at the lower end of the magnetic retainer is tightly pressed against the metal floor or metal component surface, and the strong magnetic attraction force of the magnetic retainer is used to initially attract and fix the base plate 1 to the metal mounting surface, achieving rapid initial positioning of the base plate 1. After the initial positioning is completed, the operator passes the fixing bolts through the two fixing holes 2 opened at both ends of the base plate 1, and locks the base plate 1 firmly to the metal mounting surface by tightening the nuts. On the mounting surface, secondary reinforcement of base plate 1 is achieved to ensure that base plate 1 will not shift or shake during subsequent wiring operations. When the installation location is sandy or soft soil, the operator needs to remove the magnetic fixing device from the magnetic frame and align the top of the conductive cone 4 with the internal thread of the threaded sleeve 3 and screw it in, so that the conductive cone 4 is fixedly installed at the lower center of base plate 1. Then, the tip of the conductive cone 4 is vertically inserted into the sandy soil, and the grounding operation is achieved by the conductive cone 4 penetrating deep into the ground. At this time, base plate 1 forms a reliable electrical connection with the earth through conductive cone 4. After base plate 1 is fixed, the operator clamps and fixes the end of the high-voltage grounding cable through the cable connector fixed at the upper center of base plate 1, so that the high-voltage grounding cable forms a complete grounding loop with the earth through the cable connector, base plate 1 and conductive cone 4 or magnetic fixing device, thereby realizing the safe grounding connection operation of the high-voltage grounding cable.

[0030] Specifically: Each magnetic frame includes a mounting frame 25, which is fixedly installed on one side of the lower end of the base plate 1. A third magnetic block 26 is fixedly installed in the center of the mounting frame 25. The top of the magnetic fastener is movably embedded in the mounting frame 25 and fits against the bottom of the third magnetic block 26. The magnetic fastener includes a fixing plate 27, the top of which is movably embedded in the mounting frame 25. The center of the upper wall of the fixing plate 27 fits against the third magnetic block 26. A fourth magnetic block 28 is fixedly installed in the center of the lower wall of the fixing plate 27.

[0031] When the construction environment is a metal mounting surface, the worker first aligns the fixing plate 27 at the top of the magnetic fastener with the opening at the bottom of the mounting frame 25, and pushes the fixing plate 27 vertically upward into the mounting frame 25. When the center of the upper wall of the fixing plate 27 is in contact with the lower end of the third magnetic block 26 fixedly installed in the center of the mounting frame 25, the third magnetic block 26 generates magnetic attraction to attract the fixing plate 27, so that the fixing plate 27 is stably held in the mounting frame 25 and will not fall off on its own, thus completing the rapid assembly between the magnetic fastener and the magnetic frame. After the magnetic fastener is assembled, the worker moves the base plate 1 down so that the lower end of the fourth magnetic block 28 fixedly installed in the center of the lower wall of the fixing plate 27 contacts the metal ground or metal component surface. At this time, the magnetic force of the fourth magnetic block 28 attracts and fixes the entire base plate 1 to the metal mounting surface, realizing the rapid initial positioning of the base plate 1. The base plate 1 can be temporarily fixed on the metal mounting surface without the use of bolts, which effectively improves the installation efficiency of the device on the metal mounting surface.

[0032] The cable connector includes a fixed frame 5, which is fixedly installed at the center of the upper side of the base plate 1. A groove 6 is formed on the upper wall of the fixed frame 5, and a first magnetic block 7 is fixedly embedded in the center of the groove 6. A sliding mount is movably embedded in the groove 6, and a clamp is fixedly installed at the top of the sliding mount. The sliding mount includes a sliding block 8, the lower end of which is movably embedded in the groove 6. A second magnetic block 9 is fixedly embedded at the center of the lower wall of the sliding block 8, and the second magnetic block 9 is in contact with the first magnetic block 7. A connecting block 10 is fixedly installed at the top of the sliding block 8, and positioners are fixedly installed on both sides of the connecting block 10. Positioning holes 11 are formed at the center of the front and rear sides of the fixed frame 5. The magnetic poles of the second magnetic block 9 and the first magnetic block 7 are opposite. Since the magnetic poles of the second magnetic block 9 and the first magnetic block 7 are opposite, when the sliding block 8 slides in the groove 6 to the position of the first magnetic block 7, the second magnetic block 9 and the first magnetic block 7 generate magnetic fields in opposite directions that interact with each other, thereby forming a magnetic attraction force that makes the sliding block 8 automatically pulled toward the first magnetic block 7 and fit tightly with it.

[0033] Each positioner includes a hinge seat 12, which is fixedly installed at the center of the side wall of the connecting block 10. A positioning plate 13 is hinged to the hinge seat 12 via a shaft. A positioning block 14 is fixedly installed on one side of the lower end of the positioning plate 13. One end of the positioning block 14 is movably embedded in the positioning hole 11. An installation plate 15 is fixedly installed on the lower end of the hinge seat 12. A spring 16 is connected between one side of the bottom end of the installation plate 15 and the positioning plate 13.

[0034] The clamp includes a clamping frame 17, which is a C-shaped clamping frame. This C-shaped structure forms an open cable entry on the side of the frame, providing ample operating space for workers to place and remove high-voltage grounding cables. The clamping frame 17 is fixedly installed on the top of the connecting block 10. The clamping frame 17 has operating slots 18 at both ends of its side wall. A lower pressure plate 19 is movably embedded in the operating slot 18. An installation rod 20 is vertically installed on the outside of the lower pressure plate 19. A rack 21 is fixedly installed on the outer wall of the installation rod 20. A driver is fixedly installed at the lower end of the center of the outer wall of the clamping frame 17, and the driver meshes with the rack 21.

[0035] During the assembly of the cable connector, the operator first places the end of the high-voltage grounding cable to be grounded into the holder and uses the clamping mechanism on the holder to initially clamp and fix the cable end, keeping it stably inside the holder. Then, the operator aligns the bottom of the sliding mount with the groove 6 opened on the upper surface of the fixed frame 5 and slowly pushes the sliding mount into the groove 6 along the guide direction of the groove 6. Under the constraint of the groove 6, the sliding mount slides smoothly along the length of the fixed frame 5. When the sliding mount slides to the center of the groove 6, the magnetic component at the bottom of the sliding mount is aligned with the first magnetic block 7 fixedly embedded in the center of the groove 6. At this time, the magnetic force generated by the first magnetic block 7 attracts the magnetic component at the bottom of the sliding mount, causing the sliding mount to automatically adhere to the predetermined center position of the groove 6 under the magnetic attraction. This achieves rapid initial positioning of the sliding mount, ensuring that the sliding mount is installed in place and in an accurate position, avoiding installation offset problems caused by human operation errors.

[0036] When the worker inserts the lower end of the sliding block 8 into the groove 6 at the upper end of the fixed frame 5 and pushes the sliding block 8 towards the center of the groove 6, the sliding block 8 maintains a linear trajectory under the guidance of the groove 6. When the sliding block 8 moves to the predetermined center position of the groove 6, the second magnetic block 9 fixedly embedded at the center of the lower wall of the sliding block 8 is exactly aligned and attached to the first magnetic block 7 fixedly embedded at the center of the groove 6. Since the magnetic poles of the second magnetic block 9 and the first magnetic block 7 are opposite, a magnetic attraction force is generated between them. Under the action of this magnetic attraction force, the sliding block 8 is automatically attracted and stably held in the center position of the groove 6, thus completing the initial movement of the sliding block 8. Simultaneously, as the sliding block 8 slides within the slide groove 6, the two positioners fixedly installed on both sides of the connecting block 10 move synchronously with the connecting block 10. When the sliding block 8 is magnetically attracted to the predetermined position at the center of the slide groove 6, the two positioners are exactly aligned with the two positioning holes 11 opened at the center of both sides of the fixed frame 5. The locking component at the bottom of the positioner automatically embeds into the corresponding positioning hole 11 under the action of the elastic element, thereby limiting the sliding freedom of the sliding block 8 within the slide groove 6, preventing the sliding block 8 from accidentally sliding or moving along the slide groove 6 during subsequent clamping operations, and ensuring that the clamp always remains in the central working position of the cable connector.

[0037] When the sliding block 8 slides to the predetermined center position in the slide groove 6, the positioners on both sides of the connecting block 10 move synchronously with the connecting block 10 to the position directly opposite the positioning holes 11 on both sides of the fixed frame 5. In this state, the spring 16 connecting the mounting plate 15 and the positioning plate 13 is in a stretched state. The elastic restoring force of the spring 16 pulls the lower end of the positioning plate 13 to swing towards the side wall of the fixed frame 5. Since the positioning plate 13 is hinged to the hinge seat 12 through the shaft, the positioning plate 13 rotates around the shaft in the hinge seat 12 under the action of the spring 16. This causes the positioning block 14, which is fixedly installed on one side of the lower end of the positioning plate 13, to move towards the side wall of the fixed frame 5 as the positioning plate 13 swings. When the positioning block 14 moves to the positioning hole on the side wall of the fixed frame 5... When 11 is aligned, the positioning block 14 automatically inserts into the positioning hole 11 under the continuous pulling force applied by the spring 16, realizing the engagement and locking of the positioning block 14 and the positioning hole 11. After the positioning block 14 is embedded in the positioning hole 11, the sliding freedom of the sliding block 8 in the slide groove 6 is completely restricted, and the sliding block 8 cannot continue to slide or move backward in the slide groove 6, thereby realizing the reliable positioning and locking of the sliding block 8. When it is necessary to remove the sliding mount from the fixed frame 5, the operator only needs to push the positioning plate 13 outward, so that the positioning plate 13 swings outward around the axis in the hinge seat 12, driving the positioning block 14 out of the positioning hole 11. At the same time, the spring 16 is stretched to store energy, which releases the sliding limit of the sliding block 8 and removes the sliding mount from the slide groove 6.

[0038] When clamping the high-voltage grounding cable, the operator first horizontally inserts the exposed conductor portion of the high-voltage grounding cable end into the clamping frame 17 through one side opening, ensuring that the exposed conductor end of the cable is placed within the clamping space between the bottom wall of the clamping frame 17 and the lower pressure plate 19, so that the cable is directly below the lower pressure plate 19. After the cable is in place, the operator operates the driver located at the lower end of the center of the outer wall of the clamping frame 17, causing the transmission component inside the driver to start operating. When the driver operates, it drives the rack 21 meshing with it to move downwards in the vertical direction. The rack 21 drives the mounting rod 20 fixedly installed on its inner side to move downwards simultaneously. The moving mounting rod 20 then drives the vertically mounted lower pressure plate 19 at its lower end to descend smoothly in the vertical direction under the guidance and constraint of the operating slot 18. As the lower pressure plate 19 continues to descend, the lower end face of the lower pressure plate 19 gradually approaches and presses against the exposed conductor surface of the high-voltage grounding cable end until the lower pressure plate 19 tightly presses and fixes the high-voltage grounding cable end to the inner bottom wall of the clamping frame 17, so that a stable and low-resistance electrical contact interface is formed between the exposed conductor of the high-voltage grounding cable end and the clamping frame 17, thereby realizing reliable engagement and tight clamping of the high-voltage grounding cable in the clamp, and ensuring that the electrical connection between the grounding cable and the clamping frame 17 has good conductivity.

[0039] Specifically: The driver includes a mounting bracket 22, which is fixedly installed at the lower end of the center of the outer wall of the clamping frame 17. The mounting bracket 22 is movably fitted onto the outside of the rack 21. A worm gear 23 is movably installed inside the mounting bracket 22 via a bearing. One side of the worm gear 23 meshes with the rack 21. An operating nut 24 is fixedly installed at the top of the worm gear 23.

[0040] When securing the high-voltage grounding cable, the operator first uses a wrench or socket wrench to clamp and secure the operating nut 24, which is fixedly installed at the top of the worm gear 23. Then, the operating nut 24 is rotated clockwise. The operating nut 24 drives the worm gear 23 to rotate synchronously under the bearing support within the mounting bracket 22. During the rotation of the worm gear 23, the helical teeth on the outer wall of the worm gear 23 mesh with the teeth on the side of the rack 21. Due to the self-locking transmission relationship between the worm gear 23 and the rack 21, the rotational motion of the worm gear 23 is precisely converted into the linear motion of the rack 21 in the vertical direction. The operator continues to rotate the operating nut 24, and the worm gear 23... As the rotation continues, the rack 21 moves smoothly downward under the drive of the worm gear 23. The rack 21 drives the mounting rod 20 and the lower pressure plate 19 to move downward synchronously, gradually increasing the clamping force of the lower pressure plate 19 on the high-voltage grounding cable. When the high-voltage grounding cable is tightly pressed against the inner bottom wall of the clamping frame 17 by the lower pressure plate 19, the operator stops rotating the operating nut 24. Because the meshing of the worm gear 23 and the rack 21 has a self-locking characteristic, even if the operator removes the external force, the rack 21 cannot be pushed back upward under the drive of the clamping reaction force, thus ensuring that the clamping force is maintained stably and will not loosen due to vibration or external force, effectively ensuring the long-term reliable clamping of the high-voltage grounding cable.

[0041] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
