Description

Technical Field

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

[0002] ‌The main purpose of using a grounding rod in high-voltage lines 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 high-voltage lines. With the progress of technology, intelligent monitoring devices can be installed on the grounding rod to collect ground wire positioning and elevation data, analyze the hanging state data, determine whether it is mis-hung, and remotely transmit the data, enabling 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. When installing, 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. When installing, it needs to be clamped one by one, and the height of the high-voltage line is relatively high. Therefore, long-term high-altitude operations pose a greater safety hazard. 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, in the event of extreme weather, if the high-voltage grounding rod is blown by strong wind, it may cause the grounding rod to shift or fall off, making it unable to effectively ground. If the line is energized or there is a sudden voltage at this time, an effective protection circuit cannot be formed, increasing the risk of electric shock to operating personnel or equipment damage. At the same time, if the loose grounding rod is blown near the energized 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 breakage or falling in the long term. Summary of the Invention

The multiple synchronous pressing frames 805 are respectively movably installed on the multiple T-shaped frames 701, and the multiple synchronous pressing frames 805 synchronously squeeze the multiple wedge-shaped push blocks 702 to move. It should be noted that in the embodiment of the present invention, in case of extreme weather, the driving frame 806 is squeezed, the driving frame 806 moves downward and synchronously drives the multiple synchronous pressing frames 805 to move. The synchronous pressing frames 805 move to squeeze 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 wire 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, ensuring the braking effect on the chuck 2.

Move the chuck 2 so that the chuck 2 moves on the bottom side of the integrated strip 6. At the same time, the chuck 2 slides on the bottom side of the driving frame 806 through the synchronous pressing frame 805. After moving in place, tighten the position locking bolt 707 so that the position locking bolt 707 locks the intelligent monitor 10 on the bottom side of the integrated strip 6, and the chuck 2 can be fixed at the required position.

[0028] Please continue to refer to the attached instructions Figure 3 - Figure 7, Further specifically, in the embodiment of the present invention, two limiting transverse movement grooves 704 are formed on the T-shaped frame 701, and two wedge-shaped push blocks 702 on the same side are respectively slidably installed in the two limiting transverse movement grooves 704; a return spring 705 is installed on one inner wall of the limiting transverse movement groove 704, and the other end of the return spring 705 is installed on the wedge-shaped push block 702.

The windward plate 804 is blown to drive the follower pressing plate 803 to rotate on the rotating support frame 802. 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 pressing plate 803, and then drives the driving frame 806 to move, realizing the function of active braking.

[0030] Please continue to refer to the attached drawings of the specification Figure 3 - Figure 7 , Further specifically, in the embodiment of the present invention, synchronous sliding blocks 809 are slidably installed on both inner walls of the driving frame 806. Two installation 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 installed in the two installation 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 installed on both sides of the synchronous sliding block 809, and the ends of the two support return springs 811 away from each other are respectively installed on the inner walls of both sides of the driving frame 806; In addition, two vertical sliding holes 812 are formed in the top side of the U-shaped support frame 801, and two vertical limiting rods 813 are installed on the bottom side of the driving frame 806. The two vertical limiting rods 813 are respectively slidably installed in the two vertical sliding holes 812.

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 plurality of synchronous pressing frames 805 to move, 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.

[0031] More specifically, in the embodiment of the present invention, two pushing rollers 807 are rotatably installed on the synchronous pressing frame 805. The movement of the synchronous pressing frame 805 squeezes the two wedge-shaped push blocks 702 through the two pushing rollers 807 to move. 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 through the two pushing rollers 807 to move, 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.

[0032] Further, please refer to the attached drawings of the specification Figure 8 - Figure 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 the plurality of tongue shafts 11. Specifically, the auxiliary locking device 9 includes a turning plate 901. The turning plate 901 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 the 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 to lock the plurality of tongue shafts 11, realizing the automatic locking of the elastic tongues 3 and ensuring the stability of the chuck 2 after being clamped on the high-voltage wire.

[0033] 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 flipping 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 sides of the two driving rods 905 away from each other, synchronizing shafts 907 are installed on the sides of the two driving rods 905 away from each other, and the two synchronizing 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 pushing up the stretching plate 912, the two L-shaped push-pull frames 906 are synchronously driven to move, the movement of the L-shaped push-pull frame 906 drives the driving rod 905 to rotate through the synchronizing shaft 907, and the driving rod 905 drives the flipping plate 901 to rotate through the middle rotating shaft 910, so as to achieve the purpose of conveniently flipping the flipping plate 901.

[0034] Please continue to refer to the attached drawings of the specification Figure 8 - Figure 11 Furthermore specifically, in the embodiment of the present invention, two installation grooves 909 are formed in 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 resilience of the torsion spring 911, it can help the middle rotating shaft 910 to reset, and further achieve the purpose of automatically resetting the flipping plate 901.

[0035] Even more specifically, in the embodiment of the present invention, the two L-shaped push-pull frames 906 are both movably installed on one socket seat 904 away from the integrated strip 6, and a stretching plate 912 is installed on the bottom sides of the two L-shaped push-pull frames 906; a downward pulling spring 908 is installed on the top side of the stretching plate 912, and the top end of the downward pulling spring 908 is installed on the bottom side of the socket seat 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 pulling spring 908 is stressed and contracts. The movement of the L-shaped push-pull frame 906 drives the driving rod 905 to rotate through the synchronizing shaft 907, and the driving rod 905 drives the flipping plate 901 to rotate through the middle rotating shaft 910, thereby driving 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 wire; after installation, when the stretching plate 912 is released, under the downward pulling force of the downward pulling spring 908, the stretching plate 912 drives the two L-shaped push-pull frames 906 to move downward and reset, and then the flipping plate 901 is reset. Then, the flipping 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.

[0036] In summary, the working principle of an intelligent grounding device for high-voltage lines provided by an embodiment of the present invention is as follows: When installing the chuck 2, first push up the tension plate 912, synchronously drive the two L-shaped push-pull frames 906 to move and make the pull-down spring 908 contract under force. The movement of the L-shaped push-pull frame 906 drives the drive rod 905 to rotate through the synchronizing shaft 907. The drive 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 grooves 909 and drives the two torsion springs 911 to be stressed. The rotation of the turning plate 901 drives the multiple synchronous locking frames 902 to disengage from the multiple locking gears 903, unlocking the multiple elastic tongues 3. At this time, the integrated strip 6 is placed on the high-voltage line through the insulating handle 1, and then moved down to clamp the multiple chucks 2 on the multiple high-voltage lines, so that the chuck 2 is clamped on the high-voltage line through the two elastic tongues 3. After the installation is completed, release the tension plate 912. Under the downward pulling force of the pull-down spring 908, the tension plate 912 drives the two L-shaped push-pull frames 906 to move down and reset, thereby making the turning plate 901 reset. The turning plate 901 drives the multiple synchronous locking frames 902 to rotate and engage with the multiple locking gears 903 to lock the multiple tongue shafts 11, and further lock the multiple elastic tongues 3 to ensure that the chuck 2 can be stably clamped on the high-voltage line; Further, in case of extreme weather, the wind blows the windward plate 804. The windward plate 804 rotates on the rotating support frame 802 through the follower pressing plate 803, and squeezes the driving frame 806 to move by pushing the rotating rod 808. 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 multiple synchronous pressing frames 805 to move. The movement of one synchronous pressing frame 805 squeezes the two wedge-shaped push blocks 702 to move through the two pushing rollers 807. The two wedge-shaped push blocks 702 slide in the T-shaped frame 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, effectively avoiding the problem that the chuck 2 slides on the high-voltage line and causes a safety accident. 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 the wind force to ensure the braking effect on the chuck 2; In addition, when there is a slight wind, the windward plate 804 rotates on the rotating support frame 802 through the follower pressing plate 803, so that the follower pressing plate 803 pushes any one of the rotating rods 808 to rotate and move. The rotating rod 808 drives the synchronous sliding block 809 to slide in the driving frame 806 and drives the two support return springs 811 to be stressed. Then, under the reaction force of the two support return springs 811, the synchronous sliding block 809 is reset to buffer the follower pressing plate 803 and avoid the problem that the chuck 2 is affected by slight wind force or external force, resulting in the inconvenience of installing or disassembling the chuck 2.
