Description

Technical Field

[0001] The utility model relates to the technical field of rotary flexible anti-dance spacer bars, and more particularly to a rotary flexible anti-dance spacer bar. Background Art

[0002] The anti-dancing spacer is an anti-vibration and anti-dancing device used for high-voltage transmission lines. Its main function is to reduce the vibration and dancing of the transmission line under wind load or other external forces, prevent accidents such as line tripping, line breaking or tower collapse, and ensure the safe and stable operation of the power grid.

[0003] The swivel-type flexible anti-vibration spacer is a specially designed anti-vibration spacer primarily used on high-voltage transmission lines, particularly in areas subject to high wind loads. Its key feature is that the spacer's clamps can pivot freely, or within a certain angle range, to accommodate the deformation and vibration of the conductor under wind loads. It primarily consists of a spacer body and flexible connectors, such as springs and rubber, that absorb the conductor's vibration energy and reduce wear.

[0004] In the prior art, when the wire clamp structure in the rotary flexible anti-dancing spacer is connected to the cable, the wire clamp body and the wire clamp gland are wrapped around the cable, and the bottom end of the wire clamp gland is locked and fixed to the wire clamp body by means of a bolt and a nut. In this process, the locking of the bolt and the nut mainly relies on manual screwing. During use, the cable will vibrate due to wind resistance, which can easily lead to loosening between the bolt and the nut, affecting the connection stability between the wire clamp and the cable in the rotary flexible anti-dancing spacer, and affecting the overall stability of use.

[0005] In addition, the wire clamp structure in the existing rotary flexible anti-dance spacer is mostly installed on the spacer body with a fixed length. When connected to the cable, it is not convenient to flexibly adjust the connection position according to the position of the cable, affecting the overall convenience and flexibility during installation.

[0040] The utility model provides an installation cavity 9 on the connecting section 5, in which a limit plate 10 is elastically installed, a limit column 11 is provided on the limit plate 10, and a limit groove 12 is provided on the nut 8 to cooperate with the limit column 11.

A limit telescopic column 26 is provided between the inner wall of the installation cavity 9 and the limit plate 10.

[0041] In this way, when the locking and fixing between the wire clamp cover 4 and the wire clamp body 3 are achieved by the locking bolt 6 and the locking nut 7, the limiting column 11 on the limiting plate 10 can be engaged into the limiting groove 12 on the nut 8, thereby limiting the rotation of the nut 8, avoiding the loosening caused by the shaking of the locking bolt 6 and the locking nut 7 when the cable is driven by wind during use, and improving the stability of the rotary flexible anti-dance spacer during installation and use.

[0042] The utility model is provided with a telescopic section 13 at the bottom end of the wire clamp body 3, and the bottom end of the telescopic section 13 is telescopically connected to a fixed section 14, and an elastic damping connector 15 is provided between the fixed section 14 and the profile frame 1. In this way, when the rotary flexible anti-dance spacer is installed, the installation position of the rotary wire clamp body 2 can be adjusted appropriately, thereby improving the flexibility of the rotary wire clamp body 2 during installation.

[0043] The present invention provides a telescopic slot 16 on the fixed section 14, the telescopic section 13 is slidably located in the telescopic slot 16, and a telescopic adjustment structure is provided between the telescopic section 13 and the fixed section 14;

[0044] Specifically, the telescopic adjustment structure includes an adjustment slot 17 opened outward along the telescopic slot 16, and an adjustment column 18 is threadedly provided on the telescopic section 13. The tail end of the adjustment column 18 extends to the outside of the adjustment slot 17 and is provided with a locking knob 19.

[0045] In this way, through the setting of the telescopic slot 16, the telescopic section 13 can be telescopically adjusted on the fixed section 14, thereby realizing flexible adjustment of the installation position of the wire clamp body 3. When the telescopic section 13 moves, it will drive the adjusting column 18 to move in the adjusting slot 17. When it moves to the appropriate position, the locking knob 19 is tightened, so that the adjusting column 18 drives the locking knob 19 to move inward, thereby realizing the locking and fixation of the adjusting column 18 in the adjusting slot 17, and then realizing the locking and fixation of the telescopic section 13 on the fixed section 14, thereby realizing the locking and fixation of the installation position of the wire clamp body 3.

[0046] See also Figures 1-8As an implementation method of the locking knob 19: a limiting section 20 is set on the inner side of the locking knob 19, and a limiting card slot 21 is opened on the adjustment slot 17 to cooperate with the limiting section 20. The diameter of the limiting card slot 21 is larger than the diameter of the adjustment column 18 and smaller than the diameter of the locking knob 19.

[0047] Specifically, when the locking knob 19 moves, the limit section 20 can be driven to move. When the locking knob 19 is rotated and locked, the limit section 20 will be driven to engage into the limit slot 21, thereby improving the connection stability between the locking knob 19 and the fixed section 14, improving the locking stability of the telescopic section 13 on the fixed section 14, and improving the installation stability of the wire clamp body 3.

[0048] The utility model is provided with a clamping column 27 on the inner side of the locking nut 7, and a clamping groove 28 is provided on the outer side of the bottom end of the wire clamp body 3, and the clamping column 27 and the clamping groove 28 are interference-fitted;

[0049] In this way, when the wire clamp cover 4 and the wire clamp body 3 are locked and fixed, the locking nut 7 can be initially fixed to the wire clamp body 3 through the interference fit between the locking column 27 and the locking groove 28. In this way, the installation limit of the locking nut 7 is achieved, thereby avoiding the rotation of the locking nut 7 during locking, and improving the convenience and stability of the overall installation.

[0050] See also Figures 1-8 , as an implementation method of the rotary flexible anti-dance spacer: a mounting box 29 is installed at the top and bottom middle positions of the frame 1, two groups of limit springs 30 are symmetrically installed in the mounting box 29, and a counterweight block 31 is arranged between the two groups of limit springs 30. The counterweight block 31 can be connected to the inner wall of the mounting box through a ball structure, and the ball is rotatably embedded in the counterweight block 31 to reduce the friction between the counterweight block 31 and the inner cavity of the mounting box 29 and improve the anti-displacement performance.

[0051] Specifically, when the whole is subjected to wind impact, the profile frame 1 will drive the installation box 29 to displace relative to the counterweight block 31, thereby compressing the limit spring 30 at one end and stretching the limit spring 30 at the other end, which will generate a rotational force pulling the installation box 29 back. In this way, the overall stability can be improved, the vibration and dancing of the transmission line under wind load or other external forces can be reduced, and accidents such as line tripping, line breaking or tower collapse can be prevented, thereby ensuring the safe and stable operation of the power grid.

[0052] See also Figures 1-8 As an implementation of the installation box 29 , a connecting ear 32 is provided on the top of the installation box 29 , and a connecting bolt 33 is provided between the connecting ear 32 and the profile frame 1 .

[0053] Specifically, the detachable connection between the mounting box 29 and the profile frame 1 can be achieved through the cooperation of the connecting ear 32 and the connecting bolt 33, so that a mounting box 29 with a different type of counterweight 31 can be selected according to the use environment of the rotary flexible anti-dance spacer, thereby improving the flexibility and convenience of use.

[0054] In summary, when the overall equipment is in use:

[0055] Place the power transmission cable between the clamp body 3 and the clamp gland 4. When tightening, snap the clamp gland 4 shut and insert the locking bolt 6 through the connecting section 5, so that the tail end of the locking bolt 6 is threadedly engaged with the locking nut 7.

[0056] During this process, the engaging column 27 on the locking nut 7 can be located in the engaging groove 28 on the wire clamp body 3, thereby limiting the rotation of the locking nut 7 and improving the screwing stability of the locking bolt 6;

[0057] At the same time, the pressing button 24 is pressed downward, and the pressing frame 23 is driven to move in the pressing groove 22 by the pressing button 24. The movement of the pressing frame 23 drives the limiting plate 10 to move in the installation cavity 9, so that the limiting column 11 is located in the installation cavity 9;

[0058] When the nut 8 is screwed in and fixed, the limiting groove 12 on the nut 8 is aligned with the limiting post 11 on the limiting plate 10. The pressing force of the contact button 24 and the support spring 25 can push the limiting plate 10 outward, so that the limiting post 11 can be engaged into the limiting groove 12, thereby achieving the rotation limit of the nut 8. In this way, the overall loosening of the rotary wire clamp body 2 during use due to vibrations caused by factors such as the cable being driven by wind can be avoided, thereby improving installation and stability.

[0059] During the installation process, the position of the telescopic section 13 on the fixed section 14 can be adjusted. The telescopic groove 16 is provided to realize the telescopic adjustment of the telescopic section 13 on the fixed section 14, thereby realizing the flexible adjustment of the installation position of the wire clamp body 3. When the telescopic section 13 moves, it drives the adjusting column 18 to move in the adjusting groove 17. When it moves to the appropriate position, the locking knob 19 is tightened, so that the adjusting column 18 drives the locking knob 19 to move inward, thereby realizing the locking and fixing of the adjusting column 18 in the adjusting groove 17, and then realizing the locking and fixing of the telescopic section 13 on the fixed section 14, thereby realizing the locking and fixing of the installation position of the wire clamp body 3, improving the installation flexibility;

[0060] When the locking knob 19 moves, the limiting section 20 can be driven to move. When the locking knob 19 is rotated and locked, the limiting section 20 is driven to engage with the limiting slot 21, thereby improving the connection stability between the locking knob 19 and the fixed section 14, improving the locking stability of the telescopic section 13 on the fixed section 14, and improving the installation stability of the wire clamp body 3;

[0061] During use, when the whole is subjected to wind impact, the profile frame 1 will drive the installation box 29 to displace relative to the counterweight block 31, thereby compressing the limit spring 30 at one end and stretching the limit spring 30 at the other end, which will generate a rotational force pulling the installation box 29 back. In this way, the overall stability can be improved, the vibration and dancing of the transmission line under wind load or other external forces can be reduced, and accidents such as line tripping, line breakage or tower collapse can be prevented, thereby ensuring the safe and stable operation of the power grid.
