Description

Technical Field

[0001] The utility model belongs to the technical field of tubular busbars, and particularly relates to a locking structure for a high-voltage composite shielded tubular busbar. Background Art

[0002] A tubular busbar is a power transmission device, which is made of a copper tube or an aluminum tube and is tubular. Due to its tubular structure, the surface area of the tubular busbar is relatively large, capable of withstanding a large current. At the same time, the tubular structure of the tubular busbar is conducive to heat dissipation, which can effectively reduce the temperature of the busbar. Tubular busbars are widely used in power systems, such as substations, power plants, transmission lines, etc. It can be used to transmit high-voltage and large-current electricity and is an indispensable part of the power system.

[0003] In order to ensure the stability of the tubular busbar during operation and prevent it from loosening and displacing, a bolt locking structure is usually used to fix the tubular busbar. Its structure is relatively simple, easy to understand and operate, does not require complex design and manufacturing processes. At the same time, the installation process of the bolts is relatively convenient and can be completed quickly, saving installation time and labor costs. In addition, fixing by bolts can provide a stable and reliable fixing effect to ensure that the tubular busbar will not loosen or displace during operation.

[0028] As Figures 2 to 4 shown, a locking structure for a high-voltage composite shielded tubular busbar includes:

[0029] A base 1 and a movable seat 2. Mounting holes 3 are provided at the four corners inside the base 1. The mounting holes 3 are used to fix the base 1. A first chute 5 is arranged inside the base 1. The movable seat 2 is arranged on one side of the base 1 and is in contact with the base 1. The first chute 5 is used to provide a sliding track for the movable seat 2;

[0030] The ferrule 4 can sleeve the tubular busbar, thus facilitating the fixation of the tubular busbar. A second chute 8 is provided inside the movable seat 2, and the second chute 8 can allow one side of the ferrule 4 to be slidably connected therein, thus facilitating the opening and closing of the ferrule 4. A pressure rod 9 is slidably connected inside the ferrule 4, and a first insertion block 14 is fixedly connected to one side of the pressure rod 9. Then, the movement of the first insertion block 14 can be controlled by the pressure rod 9. A first slot 11 is provided inside the movable seat 2, and the first insertion block 14 and the first slot 11 have the same size, so that the outer wall of the first insertion block 14 can be tightly inserted into the first slot 11, and thus the ferrule 4 can be fixed. A reset assembly is arranged inside the pressure rod 9, and the reset assembly includes a slide rod 12 and a compression spring 13. The compression spring 13 is sleeved on the outer wall of the slide rod 12 and can provide power for the reset of the pressure rod 9. A driving assembly is arranged inside the ferrule 4. A worm gear 20 is rotatably connected inside the ferrule 4, and a rotating ring 19 is fixedly connected to the outer wall of the worm gear 20. The rotating ring 19 can be driven to rotate by the worm gear 20. A slider 15 is slidably connected inside the ferrule 4, and a limiting rod 16 is fixedly connected to one side of the bottom of the slider 15. An arc-shaped groove 21 is provided inside the rotating ring 19, and the outer wall of the limiting rod 16 can be accurately slidably connected inside the arc-shaped groove 21. Then, under the rotation of the rotating ring 19, the slider 15 can be driven to slide through the limiting rod 16. One side of the slider 15 is fixedly connected to a clamping plate 7, so that the tubular busbar is clamped by the clamping plate 7. A connecting assembly is arranged on the outer wall of the worm gear 20, and the connecting assembly includes a clamping block 10. The clamping block 10 is fixedly connected to one side of the worm gear 20, and a clamping groove 18 is provided on the other side of the worm gear 20. The outer wall of the clamping block 10 can be slidably connected inside the clamping groove 18. Thus, after the two ferrules 4 are connected, the two worm gears 20 can rotate synchronously. The driving assembly includes a driving block 6 and a worm 17. The worm 17 is rotatably connected inside the ferrule 4, and the outer wall of the driving block 6 is fixedly connected to one end of the worm 17. Then, the worm 17 can be controlled to rotate by the driving block 6, and further drive the worm gear 20 to rotate;

[0031] Specifically, when fixing the tubular busbar, press the pressure rod 9 to make it slide out of the outer slot 11 of the second chute 8. The two side collar rings 4 can slide along the second chute 8 towards the center. After closing, release the pressure rod 9. Under the action of the second slot 23, the first insert block 14 slides out of the inside of the collar ring 4 and inserts into the inner slot 11 of the second chute 8, thus wrapping the tubular busbar. By rotating the driving block 6, the worm 17 rotates, driving the worm gear 20 and the rotating ring 19 to rotate. The arc-shaped groove 21 moves accordingly, pushing the limiting rod 16, causing the slider 15 to slide towards the center of the collar ring 4, and the clamping plate 7 fixes the tubular busbar for clamping. This mechanism can complete the fixation of the tubular busbar through simple pressing and rotating operations, without complex tools and steps. The design of the collar ring 4 and the clamping plate 7 can provide a stable clamping force to ensure that the tubular busbar will not loosen during operation. The position of the collar ring 4 can be adjusted according to the tubular busbar with different pipe diameters, having strong versatility. The clamping plate 7 is made of rubber material, which can avoid damaging the surface of the tubular busbar, and at the same time enhance the shielding effect of the tubular busbar through its insulation property. When removing the tubular busbar, press the pressure rod 9 to make it slide out of the inner slot 11 of the second chute 8. The two side collar rings 4 can slide along the second chute 8 towards the outside. After opening, release the pressure rod 9. Under the action of the second slot 23, the first insert block 14 slides out of the inside of the collar ring 4 and inserts into the outer slot 11 of the second chute 8, then the tubular busbar can be taken out. At the same time, rotate the driving block 6, drive the worm 17 to rotate, drive the worm gear 20 and the rotating ring 19 to rotate. The arc-shaped groove 21 moves accordingly, pushing the limiting rod 16, causing the slider 15 to slide towards the outside, and the clamping plate 7 releases the clamping fixation of the tubular busbar, facilitating its up and down movement and changing the locking position, thus increasing the flexibility of the device in use.

[0032] Such as Figure 1 , Figure 5 and Figure 6As shown in the figure, on both sides inside the movable seat 2, there are sliding-connected second inserting blocks 22. On both sides inside the base 1, there are provided multiple second slots 23. The outer wall of the second inserting block 22 is slidably connected inside the second slot 23, thus ensuring the stability of their connection. In the case of connection, the movable seat 2 can be kept stable on the base 1. Inside the center of the movable seat 2, there is a rotatably-connected rotating shaft 29. On one side of the outer wall of the rotating shaft 29, there is fixedly-connected a gear 26. Then the gear 26 can rotate by means of the rotating shaft 29. On both sides of the gear 26, there are rotatably-connected transmission rods 27. One side of the transmission rod 27 is rotatably connected to one side of the outer wall of the second inserting block 22 by means of a pin shaft. When the gear 26 rotates, it can drive the second inserting block 22 to slide by means of the connection of the transmission rod 27. On one side inside the movable seat 2, there is a slidably-connected rack 25. The outer wall of the rack 25 is closely meshed with the outer wall of the gear 26. And on one side of the rack 25, there is fixedly-connected a pressing block 28. Then the rack 25 can be controlled by the pressing block 28, thereby controlling the rotation of the gear 26. On the other side inside the movable seat 2, there is provided a rotating spring 24. The rotating spring 24 has good elasticity. One end of the rotating spring 24 is fixedly connected to the outer wall of the rotating shaft 29, and the other end of the rotating spring 24 is fixedly connected to the inner wall of the movable seat 2, providing a stable elastic force for the reset of the rotating shaft 29;

[0033] Specifically, when the movable seat 2 needs to be moved, press the pressing block 28 to make the rack 25 slide, drive the gear 26 to rotate, and then pull the transmission rod 27 to make the second inserting block 22 slide inwards and slide out of the second slot 23 on the inner wall of the first chute 5, so that the movable seat 2 slides along the first chute 5. This mechanism only needs to press the pressing block 28 to realize the movement of the movable seat 2, which is convenient and fast. In this mechanism, components such as the rack 25 and the gear 26 are all made of high-strength and wear-resistant alloy materials to improve their service life. After the movable seat 2 is positioned, release the pressing block 28. The rack 25 loses the restricting force on the gear 26. The rotating spring 24 coaxially fixed with the gear 26 will drive the rotating shaft 29 to rotate through its elastic acting force, making the gear 26 rotate back to its original position. The gear 26 pushes the transmission rod 27 to make the second inserting block 22 slide out of the inside of the movable seat 2 and snap into the corresponding second slot 23 on the inner wall of the first chute 5, so that the movable seat 2 is kept stable. In this mechanism, after releasing the pressing block 28, the movable seat 2 can be automatically locked in the selected position without additional operations, thus increasing the convenience of its operation. Through the cooperation of the second inserting block 22 and the second slot 23, a reliable locking effect can be provided to ensure that the movable seat 2 will not shake or move during operation. Components such as the rotating spring 24 and the transmission rod 27 can be made of high-strength and wear-resistant materials to improve their service life.

[0034] The working principle is as follows:

[0035] When fixing the tubular busbar, the pressure rod 9 can be pressed to make the pressure rod 9 slide out of the outer slot 11 of the second chute 8, so that the two side collars 4 can slide along the second chute 8 towards the center. After the two side collars 4 are closed, the pressure rod 9 can be released, and the pressure rod 9 will drive the first insert block 14 to slide out of the inside of the collar 4 under the action of the second slot 23, so as to insert into the first slot 11 on the inner side of the second chute 8, so that the two side collars 4 wrap the tubular busbar. Then, by rotating the drive block 6, the worm 17 can be driven to rotate, and the worm 17 can drive the worm wheel 20 to rotate. Then, the worm wheel 20 drives the rotating ring 19 to rotate, and the arc-shaped groove 21 inside the rotating ring 19 will move accordingly. Thus, the inner wall of the arc-shaped groove 21 pushes the limiting rod 16, and the slider 15 fixing the limiting rod 16 slides horizontally. Then, the inner wall of the arc-shaped groove 21 pushes the slider 15 towards the center of the collar 4 through the limiting rod 16, so that the clamping plate 7 on the slider 15 fixes and clamps the tubular busbar. When the movable seat 2 needs to move, the pressing block 28 can be pressed to make the rack 25 slide, so that the rack 25 drives the gear 26 to rotate. Then, the rotation of the gear 26 can pull the transmission rod 27, so that the transmission rod 27 pulls the second insert block 22 to slide inwards, and the second insert block 22 will slide out of the second slot 23 on the inner wall of the first chute 5, so that the movable seat 2 can slide along the first chute 5;

[0036] When removing the tubular busbar, the pressure rod 9 can be pressed to make the pressure rod 9 slide out of the first slot 11 on the inner side of the second chute 8, so that the two side collars 4 can slide along the second chute 8 towards the outside. After the two side collars 4 are opened, the pressure rod 9 can be released, and the pressure rod 9 will drive the first insert block 14 to slide out of the inside of the collar 4 under the action of the second slot 23, so as to insert into the first slot 11 on the outer side of the second chute 8, so that the tubular busbar can be taken out. At the same time, by rotating the drive block 6, the worm 17 can be driven to rotate, and the worm 17 can drive the worm wheel 20 to rotate. Then, the worm wheel 20 drives the rotating ring 19 to rotate, and the arc-shaped groove 21 inside the rotating ring 19 will move accordingly. Thus, the inner wall of the arc-shaped groove 21 pushes the limiting rod 16, and the slider 15 fixing the limiting rod 16 slides horizontally. Then, the inner wall of the arc-shaped groove 21 pushes the slider 15 through the limiting rod 16, so that the slider 15 slides outwards, so that the clamping plate 7 on the slider 15 releases the clamping and fixing of the tubular busbar, so as to facilitate the up and down movement of the tubular busbar, so as to facilitate the replacement of its locking position. After the movable seat 2 selects a position, the pressing block 28 can be released, and the rack 25 will lose the force restricting the gear 26. The rotating spring 24 coaxially fixed with the gear 26 will drive the rotating shaft 29 to rotate through its elastic acting force, so that the gear 26 rotates back to its original position. The gear 26 will push the transmission rod 27, so that the transmission rod 27 controls the second insert block 22 to slide out of the inside of the movable seat 2, so as to be stuck into the corresponding second slot 23 on the inner wall of the first chute 5, so that the movable seat 2 is kept stable.
