Description

Technical Field

[0001] This utility model relates to the field of power distribution network technology, specifically to an overhead support device for power distribution networks. Background Technology

[0002] The power distribution network, also known as the distribution grid, is a network composed of overhead lines, cables, towers, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. It plays an important role in distributing electrical energy within the power grid. During the laying of overhead lines, overhead support devices are often used to support and organize the cables.

[0003] Currently, existing overhead power distribution network support devices mostly use support columns and support frames to support cables and arrange them neatly. For example, in the "A 10kV Urban Power Distribution Network Single Pole-Mounted Overhead Equipment" with announcement number "CN111725766B", the structure of support columns, mounting plates, fixing plates and fixing blocks can limit and organize the cables. However, in actual use, it is difficult to quickly and conveniently restrain and limit the cables. Since the cables need to be inserted into two sets of corresponding holes, the cable ends need to be pre-guided into the holes to complete the insertion, which is not conducive to mid-process assembly or disassembly. Moreover, since the size of the holes is fixed, it has great limitations in limiting the cables of different thicknesses, resulting in poor applicability and greatly affecting the actual application effect of the device. Utility Model Content

[0004] The purpose of this utility model is to provide an overhead support device for power distribution networks. It features two symmetrically arranged fixed frames, each symmetrically equipped with multiple sets of fixed frames, connecting arms, arc-shaped positioning arms, and positioning columns. By turning the fixing handle, the upper and lower sets of positioning columns can be controlled to move closer or separate. In use, the cable can be placed between the upper and lower sets of positioning columns, and the columns are brought closer together to press against the side wall of the cable, thus securing and fixing it. With the cooperation of multiple sets of positioning columns, overhead support for the cable can be achieved quickly and efficiently. This device is not only simple and convenient to operate, facilitating mid-process assembly or disassembly, but also adaptable to fixing cables of various thicknesses, greatly improving the actual performance of the device and addressing the aforementioned shortcomings in the technology.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1-6 The overhead support device for power distribution networks shown includes:

[0030] Support column 1, with two clamps 2 symmetrically arranged at the top of support column 1, and two support frames 3 symmetrically connected between the two clamps 2, and a fixing frame 4 fixed at the top of each of the two support frames 3;

[0031] The clamp 2 is fixedly connected to the support column 1 by bolts.

[0032] Multiple reinforcing arms 6 are provided between the bottom sides of the two fixing frames 4. Based on this, the connection strength between the two fixing frames 4 can be greatly enhanced by the reinforcing arms 6.

[0033] Multiple sets of fixing seats 8 are symmetrically arranged on the top side of the two support frames 3. The top of the fixing seat 8 is connected to the fixing frame 9. The inside of the support frame 3 is provided with a slide rail 5. The bottom of the fixing seat 8 is fixed with a slider 7. The slider 7 slides in the slide rail 5, and a limit component is provided between the slider 7 and the fixing frame 4.

[0034] The limiting component includes a cavity 18 disposed in the slider 7. A second spring 19 is disposed inside the cavity 18. A stop block 20 is symmetrically fixed at both ends of the second spring 19. A limiting post 21 is connected to one end of the stop block 20 relative to the second spring 19. One end of the limiting post 21 extends to the outside of the slider 7. Multiple sets of limiting holes 22 matching the limiting post 21 are symmetrically disposed on both sides of the fixing frame 4. Based on this, by pressing the two symmetrical limiting posts 21, the limiting posts 21 drive the stop block 20 to move and squeeze the second spring 19, so that the limiting posts 21 can be disengaged from the limiting hole 22. Then the fixed frame 9 can be pulled, and the fixed frame 9 can drive the slider 7 to slide in the slide rail 5 through the fixed seat 8, so that the fixed frame 9 can move on the fixed frame 4. After the limiting posts 21 are released, under the elastic rebound of the second spring 19, the two limiting posts 21 can be quickly reset and inserted into the corresponding limiting holes 22 on both sides, so that the slider 7 can be locked and fixed. Then the position and number of fixed frames 9 on the fixed frame 4 can be adjusted according to the needs.

[0035] The side wall of the fixed frame 9 is provided with a sliding cavity 10. The sliding cavity 10 is symmetrically provided with movable limiting blocks 13 at both ends. One end of each limiting block 13 extends out of the sliding cavity 10 and is connected to a connecting arm 14. The inner ends of the two connecting arms 14 are symmetrically fixed with arc-shaped positioning arms 15. The two ends of the arc-shaped positioning arms 15 are symmetrically provided with positioning posts 16.

[0036] The fixed frame 9 is provided with a driving component, which is used to drive the two limiting blocks 13 to move towards or away from each other in the sliding cavity 10.

[0037] The drive assembly includes a bidirectional screw 11 rotatably connected to the slide cavity 10 via a bearing. The top end of the bidirectional screw 11 extends outside the fixed frame 9 and is provided with a fixed handle 12. Two limit blocks 13 are threadedly connected to both ends of the bidirectional screw 11.

[0038] Both ends of the bidirectional screw 11 are fitted with first springs 17. One end of the first spring 17 is fixedly connected to the limiting block 13, and the other end of the first spring 17 is fixedly connected to the fixing frame 9. Based on this, by setting the first spring 17, when the upper and lower sets of positioning posts 16 are close together, the first spring 17 is in its initial state. As the upper and lower sets of positioning posts 16 move away from each other, the first spring 17 can be compressed and deformed. When the cable is passed between the positioning posts 16, the elastic rebound of the first spring 17 can further ensure the stable clamping of the upper and lower sets of positioning posts 16.

[0039] By turning the fixing handle 12, the fixing handle 12 drives the bidirectional screw 11 to rotate. Then, the bidirectional screw 11 can drive the two limiting blocks 13 to move closer or further apart in the sliding cavity 10. After that, the limiting blocks 13 can drive the connecting arm 14 to move, so that the connecting arm 14 drives the positioning column 16 to move through the arc-shaped positioning arm 15. This can control the upper and lower positioning columns 16 to move closer or separate. When in use, the cable can be placed between the upper and lower positioning columns 16, and the upper and lower positioning columns 16 can be controlled to move closer to press against the side wall of the cable to bind and fix the cable. With the cooperation of the multiple positioning columns 16 and the first spring 17, the overhead support of the cable can be quickly and efficiently achieved. It is not only simple and convenient to operate, but also convenient to assemble or disassemble in the middle. It can also be adapted to fix various cables of different thicknesses, which greatly improves the actual use effect of the device.

[0040] Furthermore, by simultaneously pressing the two symmetrical limiting posts 21, the limiting posts 21 drive the stop block 20 to move and squeeze the second spring 19, which can cause the limiting posts 21 to exit the limiting hole 22. Then, the fixing frame 9 can be pulled, and the fixing frame 9 can drive the slider 7 to slide in the slide rail 5 through the fixing seat 8, so that the fixing frame 9 can move on the fixing frame 4. After releasing the limiting posts 21, under the elastic rebound of the second spring 19, the two limiting posts 21 can quickly reset and be inserted into the corresponding limiting holes 22 on both sides, so that the slider 7 can be locked and fixed. Then, the position and number of fixing frames 9 on the fixing frame 4 can be adjusted according to the needs, so as to better support the cable.

[0041] The limiting block 13 has a T-shaped structure, and the outer wall of the fixing handle 12 is provided with anti-slip ridges.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
