Description

Technical Field

[0001] This utility model relates to the field of high-voltage power transmission technology, specifically to a wiring device for high-voltage overhead power transmission lines. Background Technology

[0002] In high-voltage overhead power transmission systems, the connection device, as the core component connecting transmission lines to towers and equipment, directly determines the safe operation of the entire power transmission network and also affects the stable transmission of line current and signal continuity.

[0003] Traditional high-voltage overhead transmission line wiring devices are mostly rigid connection structures, which lack sufficient wind resistance and are prone to stress concentration caused by line swaying in strong winds, leading to faults such as terminal wear and conductor breakage. Existing buffering solutions such as rubber gaskets have drawbacks such as short lifespan and non-adjustable buffering force, failing to meet the long-term, reliable wind resistance requirements of high-voltage transmission lines. Therefore, there is an urgent need to design a new wiring device for high-voltage overhead transmission lines to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage overhead transmission line connection device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-voltage overhead transmission line connection device includes a pipe body, the inner wall of which is provided with a plurality of sliding grooves, and a slider is provided on the inner wall of the pipe body, the slider being slidably connected to the pipe body through the sliding grooves;

[0007] One end of the slider is integrally formed with a connecting tube, and the outer wall of the connecting tube has several through holes. The inner wall of the through holes is threaded with a locking nut, and the end of the slider away from the connecting tube is provided with a return spring.

[0008] Preferably, the outer wall of the pipe body is provided with an external thread, the outer wall of the external thread is provided with a connecting block, the inner wall of the connecting block is provided with an internal thread, and the connecting block is threadedly connected to the pipe body through the external thread and the internal thread.

[0009] Preferably, a connecting rod is provided at one end of the connecting block, a fixing block is provided at the end of the connecting rod away from the connecting rod, and a fixing ring is provided on one side of the fixing block.

[0010] Preferably, a take-up device is provided at the end of the tube away from the external thread, and a wire harness is provided on the inner wall of the take-up device.

[0011] Preferably, the slider has several slide bars on its periphery, and both the slider and the connecting tube are hollow cylindrical structures.

[0012] Preferably, the two ends of the return spring are respectively attached to the end faces of the slider and the tube, and the return spring is used for at least wind resistance and buffering.

[0013] In the above technical solution, the high-voltage overhead transmission line connection device provided by this utility model has the following advantages:

[0014] (1) Through the sliding cooperation between the slider and the groove and the elastic action of the return spring, the line sway caused by strong wind can be effectively buffered. When the line is subjected to wind force, the slider moves along the groove to compress or stretch the spring, converting the instantaneous impact force into elastic potential energy, reducing stress concentration at the connection point, reducing the risk of conductor strand breakage and component wear, and improving wind resistance stability.

[0015] (2) The connecting pipe through hole and locking nut facilitate the fixing of wires of different specifications. The connecting block is connected to the pipe body by thread, which is convenient for installation and disassembly. The wire take-up device can organize the wire bundle to avoid tangling. The slide bar design ensures that the slider slides smoothly. The whole system is suitable for various working conditions, extends the life of the device and reduces the operation and maintenance costs. Attached Figure Description

[0023] 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.

[0024] like Figure 1-5 As shown in the figure, a high-voltage overhead transmission line connection device provided by this utility model includes a pipe body 1. The inner wall of the pipe body 1 is provided with a plurality of sliding grooves 10. A slider 11 is provided on the inner wall of the pipe body 1. The slider 11 is slidably connected to the pipe body 1 through the sliding grooves 10. A connecting pipe 12 is integrally formed at one end of the slider 11. A plurality of through holes are provided on the outer wall of the connecting pipe 12. A locking nut 14 is threadedly connected to the inner wall of the through holes. A return spring 13 is provided at the end of the slider 11 away from the connecting pipe 12.

[0025] In this embodiment, a tube body 1 is included. The inner wall of the tube body 1 is provided with a plurality of sliding grooves 10. The sliding grooves 10 penetrate the entire axial length of the inner wall of the tube body 1, and the cross-section of the sliding grooves 10 is T-shaped. A slider 11 is provided on the inner wall of the tube body 1. The slider 11 is slidably connected to the tube body 1 through the sliding grooves 10. A matching T-shaped slide bar is provided on the periphery of the slider 11 at the corresponding position of the sliding grooves 10. The slide bar is embedded in the sliding grooves 10 to form a sliding fit, so that the slider 11 can slide freely along the axial direction of the tube body 1 and cannot rotate circumferentially.

[0026] One end of the slider 11 is integrally formed with a connecting tube 12. The axis of the connecting tube 12 coincides with the axis of the slider 11, and the two together form a through hollow channel. The outer wall of the connecting tube 12 is provided with several through holes. The axis of the through holes is perpendicular to the axis of the connecting tube 12, and the inner wall of the through holes is machined with internal threads 8.

[0027] The inner wall of the through hole is threaded with a locking nut 14. Tightening the locking nut 14 allows its end to extend into the hollow channel of the connecting tube 12, thereby fixing the component that passes through the channel. A return spring 13 is provided at the end of the slider 11 away from the connecting tube 12. The center position of the end face of the slider 11 away from the connecting tube 12 abuts against one end of the return spring 13.

[0028] Specifically, the outer wall of the pipe body 1 is provided with an external thread 9, the length of the external thread 9 is 1 / 5 of the total length of the pipe body 1, and the outer wall of the external thread 9 is provided with a connecting block 2, which is a cylindrical hollow structure.

[0029] The inner wall of the connecting block 2 is provided with an internal thread 8. The inner wall of the connecting block 2 is machined with an internal thread 8 that is compatible with the external thread 9. The connecting block 2 is connected to the pipe body 1 by the threaded engagement of the internal thread 8 and the external thread 9 through the external thread 9 and the internal thread 8. After tightening, it can be fixed by the self-locking of the thread.

[0030] Specifically, a connecting rod 3 is provided at one end of the connecting block 2, and one side of the outer wall of the connecting block 2 is welded to one end of the connecting rod 3. The axis of the connecting rod 3 is perpendicular to the axis of the connecting block 2.

[0031] A fixing block 4 is provided at the end of the connecting rod 3 away from the connecting rod 3. A fixing ring 5 is provided on one side of the fixing block 4. The end of the connecting rod 3 away from the connecting block 2 is welded perpendicularly to one side of the fixing block 4. The center position of the other side surface of the fixing block 4 is welded and fixed to one side of the fixing ring 5. The axis of the fixing ring 5 coincides with the central axis of the fixing block 4, forming a complete external fixed support structure.

[0032] Specifically, a take-up device 6 is provided at the end of the tube body 1 away from the external thread 9. A wire harness 7 is provided on the inner wall of the take-up device 6. The other end of the wire harness 7 passes through the hollow cavity of the tube body 1 and the through channel of the slider 11 and the connecting tube 12, and is fixed by the locking nut 14.

[0033] Specifically, a number of sliders are provided on the periphery of slider 11. Four sliders are evenly arranged on the periphery of slider 11 along the circumferential direction, and the length of the sliders is the same as the length of slider 11.

[0034] Both slider 11 and connecting tube 12 are hollow cylindrical structures. Their inner diameters are the same and their axes are collinear, forming a continuous threading channel.

[0035] Specifically, the two ends of the return spring 13 are respectively attached to the end faces of the slider 11 and the tube 1. One end of the return spring 13 is attached to the end face of the slider 11 away from the connecting tube 12, and the other end is attached to the inner wall step surface of the tube 1 near the take-up device 6.

[0036] The return spring 13 is used for wind resistance and buffering. When the slider 11 is subjected to an axial external force and moves in the direction of the take-up device 6, the return spring 13 is compressed and generates an elastic restoring force. When the external force disappears, the elastic restoring force of the return spring 13 pushes the slider 11 to return to its original position. The external impact force is absorbed through the extension and contraction deformation of the spring, thereby achieving the wind resistance and buffering function.

[0037] Working steps: 1. Insert the wire into the connecting tube 12, align it with the through hole and screw in the locking nut 14 until the wire is clamped, thus fixing the wire to the connecting tube 12.

[0038] 2. Place the return spring 13 inside the tube 1 and attach it to the bottom end, and attach the other end to one end of the slider 11;

[0039] Third, align the slider 11 with the slide groove 10 on the inner wall of the tube body 1, and slide the slider 11 into the tube body 1;

[0040] 4. Align the connecting block 2 with the external thread 9 on the outer wall of the pipe body 1 through the internal thread 8, and rotate the connecting block 2 clockwise until it is tightened to ensure that the two are firmly fixed.

[0041] 5. When strong winds or other severe weather occur, the wind pulls the return spring 13 of the wiring harness 7, causing the slider 11 to reciprocate, thus creating a buffer effect.

[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.
