An intelligent grounding device for high-voltage lines

Abstract

The present invention discloses an intelligent grounding device for high-voltage lines, which relates to the field of power equipment. It includes an insulating handle and a plurality of chucks. Two tongue shafts are rotatably installed in the chuck, and elastic tongues are installed on the tongue shafts. It should be noted that in the embodiment of the present invention, in extreme weather, the two brake blocks approach each other to lock and brake the high-voltage line, preventing the chuck from sliding on the high-voltage line and causing safety accidents. At the same time, the greater the wind force, the closer the two wedge-shaped push blocks are to each other, making the braking force increase with the increase of the wind force to ensure the braking effect on the chuck. In addition, through the integrated strip, multiple chucks can be installed at one time, making the installation of the grounding rod convenient, effectively reducing the time of climbing operations, reducing potential safety hazards, and locking multiple tongue shafts through the synchronous locking frame engaging with multiple locking gears, thereby locking multiple elastic tongues to ensure the stability of the connection between the chuck and the high-voltage line.

Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and particularly relates to an intelligent grounding device for high-voltage lines. Background Art

[0002] ‌The main purpose of using a grounding rod in a high-voltage line is to ensure the safety of power equipment and maintenance personnel. The grounding rod can ensure equipment safety, prevent electric shock accidents, eliminate induced voltage, and dissipate static electricity in the high-voltage line. With the progress of technology, intelligent monitoring devices can be installed on the grounding rod to collect grounding wire positioning and elevation data, analyze the hanging state data, determine whether there is a mis-hanging, and remotely transmit the data, enabling the staff to conveniently manage the grounding rod in the background, thereby making the use of the grounding rod more intelligent.

[0003] Common grounding rods are generally of the double-spring tongue type. During installation, the chuck is hung on the high-voltage line by holding an insulating rod, and the high-voltage line is clamped by two spring tongues to complete the installation of the grounding rod. However, the grounding rod is mostly used outdoors, and it is generally clamped on the high-voltage line. During installation, it needs to be clamped one by one, and the height of the high-voltage line is relatively high. Therefore, there are relatively large safety hazards in long-term high-altitude operations. In addition, the chuck is blown by the natural wind for a long time, or due to mechanical failures of the chuck itself, when the chuck is stuck on the high-voltage line, the spring tongue cannot be firmly stuck on the high-voltage line, which is extremely likely to cause problems such as poor contact, arcing, or even the grounding rod falling off; moreover, if extreme weather is encountered and the high-voltage grounding rod is blown by the wind, it may cause the grounding rod to shift or fall off, making it unable to effectively ground. If the line is charged or the voltage suddenly changes at this time, an effective protection circuit cannot be formed, increasing the risk of electric shock to the operating personnel or equipment damage. At the same time, if the loose grounding rod is blown near the live equipment, it may cause a short circuit or arc discharge, resulting in equipment tripping or even damage. Continuous wind may damage the fixing device of the grounding rod, affecting its mechanical strength, and may cause fracture or falling in the long term. Summary of the Invention

A brake driving device 8 is installed on the integrated strip 6. A plurality of sliding braking devices 7 are all connected to the brake driving device 8. The brake driving device 8 is used to drive the sliding braking device 7 to brake; the brake driving device 8 includes a U-shaped support frame 801. The U-shaped support frame 801 is installed on the integrated strip 6. A driving frame 806 is movably installed on the U-shaped support frame 801. A plurality of synchronous pressing frames 805 are slidably installed on both sides of the driving frame 806. The plurality of synchronous pressing frames 805 are respectively movably installed on the plurality of T-shaped frames 701. The plurality of synchronous pressing frames 805 synchronously squeeze the plurality of wedge-shaped push blocks 702 to move. It should be noted that in an embodiment of the present invention, in the event of extreme weather, the driving frame 806 is squeezed, the driving frame 806 moves downward to drive the plurality of synchronous pressing frames 805 to move synchronously. The movement of the synchronous pressing frames 805 squeezes the two wedge-shaped push blocks 702 to move through two pushing rollers 807. The two wedge-shaped push blocks 702 drive the two brake blocks 703 to approach each other to lock the high-voltage line for braking, and the two wedge-shaped push blocks 702 approach each other more when the wind force is greater, so that the braking force increases with the increase of the wind force to ensure the braking effect on the chuck 2.

[0050] Further specifically, in the embodiment of the present invention, a communication slot 706 is formed in the integrated strip 6, and a plurality of intelligent monitors 10 are slidably installed in the communication slot 706; in addition, a position locking bolt 707 is threadedly installed on the intelligent monitor 10, and the position locking bolt 707 locks the intelligent monitor 10 in the integrated strip 6.

It should be noted that in the embodiment of the present invention, when the two wedge-shaped push blocks 702 are squeezed, the two wedge-shaped push blocks 702 slide in the two T-shaped frames 701, and drive the two return springs 705 to contract under force. The two wedge-shaped push blocks 702 drive the two brake blocks 703 to approach each other to lock the high-voltage line for braking.

[0052] Even more specifically, in the embodiment of the present invention, the brake driving device 8 further includes a rotating support frame 802, and the rotating support frame 802 is installed on the top side of the U-shaped support frame 801; a follower pressure plate 803 is rotatably installed on the rotating support frame 802, and a windward plate 804 is installed on the top side of the follower pressure plate 803.

It should be noted that in the embodiment of the present invention, when the windward plate 804 is blown by strong wind, the windward plate 804 rotates on the rotating support frame 802 through the follower pressure plate 803, and then drives the driving frame 806 to move, realizing the function of active braking.

[0053] Please continue to refer to the attached drawings of the specification Figures 3-7, More specifically, in the embodiment of the present invention, synchronous sliding blocks 809 are slidably mounted on both inner walls of the driving frame 806. Two mounting rotation grooves 810 are formed on one side of the two synchronous sliding blocks 809 close to each other. A pushing rotating rod 808 is rotatably mounted in the two mounting rotation grooves 810 on the same straight line. The follower pressing plate 803 is located between the two pushing rotating rods 808; Support return springs 811 are mounted on both sides of the synchronous sliding block 809. One end of the two support return springs 811 away from each other is respectively mounted on the inner walls of both sides of the driving frame 806;

[0054] In addition, two vertical sliding holes 812 are formed on the top side of the U-shaped support frame 801. Two vertical limiting rods 813 are mounted on the bottom side of the driving frame 806. The two vertical limiting rods 813 are respectively slidably mounted in the two vertical sliding holes 812. It should be noted that in the embodiment of the present invention, when the wind blows the windward plate 804, the windward plate 804 drives the pushing rotating rod 808 to move through the follower pressing plate 803, and squeezes the driving frame 806 to move. The driving frame 806 vertically slides in the two vertical sliding holes 812 through the two vertical limiting rods 813. The downward movement of the driving frame 806 synchronously drives the movement of a plurality of synchronous pressing frames 805, and then drives the two brake blocks 703 to approach each other through the two wedge-shaped push blocks 702 to clamp the high-voltage wire for braking, effectively avoiding the problem that the chuck 2 slides on the high-voltage wire and causes a safety accident.

[0055] Even more specifically, in the embodiment of the present invention, two pushing rollers 807 are rotatably mounted on the synchronous pressing frame 805. The movement of the synchronous pressing frame 805 squeezes the two wedge-shaped push blocks 702 to move through the two pushing rollers 807. It should be noted that in the embodiment of the present invention, during the downward movement of the synchronous pressing frame 805, the synchronous pressing frame 805 squeezes the two wedge-shaped push blocks 702 to move through the two pushing rollers 807, which can not only achieve the purpose of squeezing the two wedge-shaped push blocks 702 to approach each other, but also effectively reduce the friction force.

[0056] Further, please refer to the accompanying instructions Figures 8-11, in the embodiment of the present invention, an auxiliary locking device 9 is further included. The auxiliary locking device 9 is installed on the insulating handle 1 and is used to lock a plurality of tongue shafts 11. Specifically, the auxiliary locking device 9 includes a turning plate 901 which is rotatably installed on the insulating handle 1. A plurality of synchronous locking frames 902 are installed on the top side of the turning plate 901. Locking gears 903 are installed at both ends of the plurality of tongue shafts 11. The synchronous locking frames 902 are engaged with the locking gears 903 to lock the tongue shafts 11. It should be noted that in the embodiment of the present invention, after the chuck 2 is clamped on the high-voltage wire by two elastic tongues 3, the turning plate 901 rotates to drive the plurality of synchronous locking frames 902 to rotate and engage with the plurality of locking gears 903, locking the plurality of tongue shafts 11 to achieve automatic locking of the elastic tongues 3 and ensure the stability of the chuck 2 after being clamped on the high-voltage wire.

[0057] Further specifically, in the embodiment of the present invention, two socket seats 904 are installed on the insulating handle 1. A middle rotating shaft 910 is installed inside the turning plate 901, and the middle rotating shaft 910 is rotatably installed on one socket seat 904 close to the integrated strip 6. In addition, driving rods 905 are installed at both ends of the middle rotating shaft 910. L-shaped push-pull frames 906 are movably installed on the side of the two driving rods 905 away from each other. Synchronous shafts 907 are installed on the side of the two driving rods 905 away from each other, and the two synchronous shafts 907 are respectively movably installed inside the two L-shaped push-pull frames 906. It should be noted that in the embodiment of the present invention, when the stretching plate 912 is pushed upward, the two L-shaped push-pull frames 906 are synchronously driven to move. The movement of the L-shaped push-pull frames 906 drives the driving rods 905 to rotate through the synchronous shafts 907, and the driving rods 905 drive the turning plate 901 to rotate through the middle rotating shaft 910, achieving the purpose of conveniently turning the turning plate 901.

[0058] Please continue to refer to the instruction manual appendix Figures 8-11 , further specifically, in the embodiment of the present invention, two installation grooves 909 are formed on one socket seat 904, and both ends of the middle rotating shaft 910 respectively pass through the two installation grooves 909. A torsion spring 911 is installed on the inner wall of the installation groove 909, and the other end of the torsion spring 911 is installed on the middle rotating shaft 910. It should be noted that in the embodiment of the present invention, when the middle rotating shaft 910 rotates, the middle rotating shaft 910 rotates in the two installation grooves 909 and drives the torsion spring 911 to be stressed. Therefore, under the restoring force of the torsion spring 911, it can help the middle rotating shaft 910 to reset, and further achieve the purpose of automatic reset of the turning plate 901.

[0059] More specifically, in the embodiment of the present invention, both of the L-shaped push-pull frames 906 are movably installed on a socket 904 away from the integrated strip 6. A stretching plate 912 is installed on the bottom sides of the two L-shaped push-pull frames 906; a downward pull spring 908 is installed on the top side of the stretching plate 912, and the top end of the downward pull spring 908 is installed on the bottom side of the socket 904. It should be noted that in the embodiment of the present invention, when pushing up the stretching plate 912, the two L-shaped push-pull frames 906 can be synchronously driven to move and the downward pull spring 908 is forced to contract. The movement of the L-shaped push-pull frame 906 drives the driving rod 905 to rotate through the synchronizing shaft 907. The driving rod 905 drives the turning plate 901 to rotate through the middle rotating shaft 910, and further drives a plurality of synchronous locking frames 902 to disengage from a plurality of locking gears 903, so that a plurality of elastic tongues 3 are unlocked, facilitating the clamping of the chuck 2 on the high-voltage line; after installation, release the stretching plate 912. Under the downward pulling force of the downward pull spring 908, the stretching plate 912 drives the two L-shaped push-pull frames 906 to move downward and reset, and then the turning plate 901 is reset. Then, the turning plate 901 drives a plurality of synchronous locking frames 902 to rotate and engage with a plurality of locking gears 903, locking a plurality of tongue shafts 11, realizing the automatic locking of the tongue shafts 11.

[0060] In summary, the working principle of an intelligent grounding device for high-voltage lines provided by the embodiment of the present invention is as follows:

[0061] When installing the chuck 2, first push up the stretching plate 912, synchronously drive the two L-shaped push-pull frames 906 to move and make the downward pull spring 908 contract under force. The movement of the L-shaped push-pull frame 906 drives the driving rod 905 to rotate through the synchronizing shaft 907. The driving rod 905 drives the turning plate 901 to rotate through the middle rotating shaft 910. At the same time, the middle rotating shaft 910 rotates in the two installation slots 909 and drives the two torsion springs 911 to be stressed. The rotation of the turning plate 901 drives a plurality of synchronous locking frames 902 to disengage from a plurality of locking gears 903, so that a plurality of elastic tongues 3 are unlocked. At this time, place the integrated strip 6 on the high-voltage line through the insulating handle 1, and then move it downward to clamp a plurality of chucks 2 on a plurality of high-voltage lines, so that the chuck 2 is clamped on the high-voltage line through the two elastic tongues 3. After completion of the installation, release the stretching plate 912. Under the downward pulling force of the downward pull spring 908, the stretching plate 912 drives the two L-shaped push-pull frames 906 to move downward and reset, and then the turning plate 901 is reset. The turning plate 901 drives a plurality of synchronous locking frames 902 to rotate and engage with a plurality of locking gears 903, locking a plurality of tongue shafts 11, and further locking a plurality of elastic tongues 3, ensuring that the chuck 2 can be stably clamped on the high-voltage line;

[0062] Furthermore, when encountering extreme weather, strong winds blow the windward plate 804, and the windward plate 804 rotates on the rotating support frame 802 through the follower pressure plate 803, and pushes the rotating rod 808 to squeeze the driving frame 806 to move, and the driving frame 806 slides vertically in the two vertical sliding holes 812 through the two vertical limit rods 813, and the driving frame 806 moves downward to synchronously drive multiple synchronous pressing frames 805 to move, and one synchronous pressing frame 805 moves to squeeze the two wedge-shaped push blocks 702 to move through the two pushing rollers 807, and the two wedge-shaped push blocks 702 slide in the T-shaped frame 701, and drive the two push-back springs 705 to contract under force, and the two wedge-shaped push blocks 702 drive the two brake blocks 703 to move closer to each other to lock the high-voltage line for braking, effectively avoiding the problem of the clamping head 2 sliding on the high-voltage line and causing safety accidents. At the same time, the greater the wind force, the closer the two wedge-shaped push blocks 702 are to each other, so that the braking force increases with the increase of wind force, thereby ensuring the braking effect on the clamping head 2;

[0063] In addition, when there is a slight breeze, the windward plate 804 rotates on the rotating support frame 802 through the follower pressure plate 803, so that the follower pressure plate 803 pushes any one of the pushing rods 808 to rotate and move, and the pushing rod 808 drives the synchronous sliding block 809 to slide in the driving frame 806, and drives the two supporting return springs 811 to be subjected to force, and then under the reaction force of the two supporting return springs 811, the synchronous sliding block 809 is driven to reset, which is used to buffer the follower pressure plate 803, so as to prevent slight wind force or external force from affecting the chuck 2, causing the chuck 2 to be inconvenient to install or disassemble.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
