Description

Technical Field

[0001] This utility model relates to the field of power technology, and in particular to a cable support with anti-galling function. Background Technology

[0002] In power transmission lines, common cable laying methods include direct burial, conduit laying, and overhead laying. Among these, overhead laying, which suspends the cable on a pole or tower, is the most widely used due to its low cost, simple construction, and ease of fault location and maintenance.

[0003] In order to cope with the changes in cable length due to thermal expansion and contraction, the cable cannot be fully taut and needs to be kept with a certain degree of slack. This results in the lack of support between the overhead cable and the pole or tower, and the cable is easily affected by strong winds in the field, which can cause large-amplitude low-frequency vibrations or galloping. Cable galloping can easily cause short circuits, wire breaks, insulator damage, and even tower collapse, threatening the safety of the power grid. In addition, frequent inspection and replacement of damaged parts increases the maintenance cost of the power system. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cable support with anti-galloping function to solve the problem that overhead cables in the prior art are easily damaged by wind, threatening the safety of the power grid and increasing the maintenance cost of the power system.

[0005] This utility model provides a cable bracket with anti-galloping function, comprising:

[0006] A support frame, on which cable clips are provided;

[0007] A guide frame is disposed between adjacent support frames, and two sliders are slidably disposed on the guide frame, with a tightening ring fixedly disposed on each slider;

[0008] A threaded rod is disposed in the guide frame and threadedly connected to the slider, wherein the threaded sections on the threaded rod that match the two sliders respectively have opposite thread directions;

[0009] A driver is mounted on the support and is rotaryly connected to the threaded rod to drive the threaded rod to rotate.

[0010] Optionally, the cross-section of the guide body of the guide frame is n-shaped.

[0011] Optionally, it also includes:

[0012] The mounting bracket is fixedly mounted on the support frame;

[0013] A rotating shaft is rotatably mounted on the mounting bracket. The rotating shaft is horizontally positioned and perpendicular to the extension direction of the guide bracket.

[0014] A rotating frame is fixedly mounted on the rotating shaft, and its extension direction points towards the cable installation area;

[0015] The rotating shaft is connected to the driver so that when the driver drives the two sliders to move away from each other and tighten the cable, it simultaneously drives the end of the rotating frame to lift and support the cable.

[0016] Optionally, the end of the rotating frame is provided with a first pulley, and the groove on the outer surface of the first pulley extends in a direction parallel to the arrangement direction of the cable.

[0017] Optionally, it also includes:

[0018] A sliding frame is disposed above the guide frame and slidably connected to the guide frame. A first end of the sliding frame is disposed near the end of the guide frame, and a second end of the sliding frame extends and is fixed to a slider. The end face of the second end of the sliding frame includes a contact slope.

[0019] The upper frame is vertically slidably disposed in the mounting frame and is connected to the rotating shaft for transmission. The bottom end of the upper frame is in contact with the contact slope.

[0020] Optionally, a second pulley is provided at the bottom end of the upper frame.

[0025] This utility model provides a cable support with anti-galloping function, which includes a guide frame between the support brackets. Two sliders are slidably mounted on the guide frame, and a tightening ring is fixedly mounted on each slider. The sliders are threadedly connected to a threaded rod, with the threads of the two sliders in opposite directions. A driver is also provided on the support bracket, and the driver is rotatably connected to the threaded rod. When the threaded rod is driven to rotate by the driver, the two sliders can be synchronously controlled to move closer or further apart. This cable support with anti-galloping function can actively control the two sliders to move closer or further apart. Therefore, based on real-time environmental conditions, when the cable gallops due to environmental influences, the two sliders are controlled to move further apart, and the tightening rings on the sliders tighten the cable, reducing the amplitude of the galloping and ensuring safety. When the environment returns to stability, the two sliders are driven to move closer together, restoring the cable to its relaxed state, thus protecting the cable and improving the reliability of the power system. Furthermore, the tension and relaxation control of cables can also disturb the cable's state, which can be used to clear snow from the cables, preventing damage to the cables due to snow pressure in icy and snowy weather. This can further improve the adaptability of the power system to harsh environments and enhance the reliability of the power system. Attached Figure Description

[0032] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0033] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0034] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] To address the problem that overhead cables are easily damaged by wind, threatening power grid safety and increasing power system maintenance costs, this invention provides a cable support with anti-galling function. It features a guide frame between support brackets, with two sliders slidably mounted on the guide frame. Each slider has a tightening ring fixedly mounted on it. The cable is laid between the support brackets and passes through the two tightening rings. The sliders are threadedly connected to a threaded rod, with the threads of the two sliders in opposite directions. A driver is also mounted on the support bracket, and the driver is rotaryly connected to the threaded rod. When the threaded rod rotates via the driver, the two sliders can be synchronously controlled to move closer or further apart. This allows for active control of the sliders' movement, controlling the cable tightening or loosening, effectively responding to environmental interference and improving the reliability of the power system.

[0037] Specifically, such as Figure 1 As shown, the support frame 1 is equipped with cable clips 2, such as straps or rings, to facilitate the positioning and installation of the cable 3. A guide frame 5 is positioned between adjacent support frames 1, and two sliders 9 are slidably mounted on the guide frame 5. A tightening ring 10 is fixedly mounted on each slider 9. The cable 3 passes through the two tightening rings 10. When the two sliders 9 move away from each other, they can move the two tightening rings 10 closer to the corresponding support frame 1, tightening the cable 3 to cope with interference from strong winds, ensuring the stability of the cable 3 and guaranteeing safety.

[0038] To drive slider 9, please refer to the following in this embodiment: Figure 5 and Figure 6 The guide frame 5 is provided with a threaded rod 8, and the slider 9 is also threadedly connected to the threaded rod 8. The threaded sections on the threaded rod 8 that match the two sliders 9 have opposite thread directions. The threaded rod 8 is connected to the driver for transmission. When the driver drives the threaded rod 8 to rotate, it can synchronously drive the two sliders 9 to move closer or further away from each other.

[0039] To ensure the reliability of the threaded rod 8 in driving the slider 9, in this embodiment, the guide body of the guide frame 5 has an n-shaped cross-section, with a groove structure inside to accommodate the threaded rod 8. The opening of this groove structure faces downwards to prevent debris from accumulating and obstructing the movement of the slider 9. The groove structure also allows for easy observation of the condition of the threaded rod 8 inside, enabling timely detection of problems and improving maintainability.

[0040] To avoid the impact of snow accumulation on the guide frame 5 on its structure, the top surface of the guide frame 5 and its components can be set as an inclined surface so that when the slider 9 moves, the snow can be made to fall off, avoiding snow accumulation and damage to the cable support. In addition, by controlling the state of the cable 3, the cable can be actively disturbed to avoid snow accumulation on the cable 3.

[0041] To further enhance the tightening ability of cable 3 and improve the fixing effect, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the support frame 1 is also equipped with an upward lifting mechanism to lift the cable and increase its tension. The upward lifting mechanism includes a mounting frame 4 fixedly mounted on the support frame 1. A rotating shaft 16 is installed inside the mounting frame 4. The rotating shaft 16 is rotatably mounted on the mounting frame 4. The rotating shaft 16 is horizontally positioned and perpendicular to the extension direction of the guide frame 5. A rotating frame 15 is fixedly mounted on the rotating shaft 16, and the extension direction of the rotating frame 15 points towards the installation area of ​​the cable 3. The rotating shaft 16 is connected to the drive driver so that when the drive drives the two sliders 9 to move away from each other and tighten the cable 3, it can simultaneously drive the end of the rotating frame 15 to lift and support the cable 3, which can further tighten the cable 3 and improve the fixing effect of the cable 3.

[0042] To avoid damage to the cable 3 by the rotating frame 15, in this embodiment, a first pulley 17 is provided at the end of the rotating frame 15. The groove on the outer surface of the first pulley 17 extends in a direction parallel to the arrangement direction of the cable 3. Thus, the first pulley 17 is spaced between the rotating frame 15 and the cable 3, and the cable 3 rolls in contact with the first pulley 17, avoiding friction damage to the cable 3.

[0043] To facilitate the driving of the rotating frame 15, in this embodiment, a sliding frame 11 is also slidably arranged on the guide frame 5. The first end of the sliding frame 11 is located near the end of the guide frame 5, and the second end of the sliding frame 11 extends and is fixed to a slider 9. The end face of the second end of the sliding frame 11 includes a contact slope. An upper frame 12 is vertically slidably arranged in the mounting frame 4. The upper frame 12 is connected to the rotating shaft 16 in a transmission manner, and the bottom end of the upper frame 12 contacts and matches the contact slope of the second end of the sliding frame 11.

[0044] When the two sliders 9 move away from each other, the sliding frame 11 can move. By contacting the inclined plane, the upper frame 12 can be driven to move upward, and then the upper frame 12 drives the rotating shaft 16 to rotate, so that the rotating frame 15 fixed on the rotating shaft 16 is lifted up, further tightening the cable 3.

[0045] To improve the smoothness of the movement of the upper frame 12, in this embodiment, a second pulley 13 is provided at the bottom of the upper frame 12, and the second pulley 13 contacts the contact slope at the second end of the sliding frame 11.

[0046] To achieve transmission between the upper frame 12 and the rotating shaft 16, in this embodiment, a rack is provided on one side of the upper frame 12, and a gear is provided on the rotating shaft 16. The rack and gear mesh with each other, smoothly driving the rotation of the rotating shaft 16. In an optional embodiment, the rotating shaft 16 can also be a camshaft. The cam structure of the upper frame 12 and the camshaft are in contact or linked, which can provide a certain impact force to disturb taut cables and improve the effect of shaking off snow accumulated on the cables.

[0047] For ease of driving, in this embodiment, as follows: Figure 4 As shown, the driver includes a motor 7, and the output shaft of the motor 7 is coaxially connected to the threaded rod 8.

[0048] To ensure the reliability of the driver, in this embodiment, the driver is also covered by a protective shell 6, such as... Figure 2 As shown, the protective shell 6, together with the support frame 1 and the guide frame 5, surrounds and encloses the drive, preventing damage to the drive from flying debris and animals in the environment.

[0049] The drive can be powered directly from the power grid and connected to the control platform via a communication system. The tensioning and fixing of the cables can be controlled by the active operation of the control platform.

[0050] In an optional embodiment, a wind sensor, a snow sensor, and a controller such as a microcontroller can also be installed on the support frame 1. The controller collects wind and snow data from the wind and snow sensors. When the wind or snow reaches a preset protection threshold, it sends a corresponding control signal to the driver. The driver then operates to tighten the fixed cable, preventing the cable from swinging under aerodynamic forces and ensuring safety. Alternatively, when there is snow accumulation, the driver can be controlled to periodically rotate forward and reverse to actively shake the cable and shake off the snow on the cable, ensuring safety.

[0051] Correspondingly, to facilitate the shaking off of snow, the part of the sliding frame 11 that contacts the guide frame 5 can also be set as a fishbone-shaped hollow type, so that the snow can be distributed between the sliding frame 11 and the guide frame 5. Thus, when the sliding frame 11 slides on the guide frame 5, the snow can be effectively shaken off, avoiding the problem that the snow is completely located on the sliding frame 11, causing the snow to be completely stationary relative to the sliding frame 11 and unable to be effectively shaken off.

[0052] To facilitate the laying of cable 3, the tightening ring 10 can be a snap ring with chamfered inner and outer edges to avoid damage to cable 3 from sharp edges.

[0053] This utility model provides a cable support with anti-galloping function, which includes a guide frame between the support brackets. Two sliders are slidably mounted on the guide frame, and a tightening ring is fixedly mounted on each slider. The sliders are threadedly connected to a threaded rod, with the threads of the two sliders in opposite directions. A driver is also provided on the support bracket, and the driver is rotatably connected to the threaded rod. When the threaded rod is driven to rotate by the driver, the two sliders can be synchronously controlled to move closer or further apart. This cable support with anti-galloping function can actively control the two sliders to move closer or further apart. Therefore, based on real-time environmental conditions, when the cable gallops due to environmental influences, the two sliders are controlled to move further apart, and the tightening rings on the sliders tighten the cable, reducing the amplitude of the galloping and ensuring safety. When the environment returns to stability, the two sliders are driven to move closer together, restoring the cable to its relaxed state, thus protecting the cable and improving the reliability of the power system.

[0054] Furthermore, the tension and relaxation control of cables can also actively disturb the cable's state, which can be used to clear snow from the cables, preventing damage to the cables due to snow accumulation in icy and snowy weather. This can further improve the adaptability of the power system to harsh environments and enhance the reliability of the power system.
