A wind-resistant high-voltage cable

Abstract

This utility model discloses a wind-resistant high-voltage cable, belonging to the field of cable technology. It includes a protective cover with a buffer assembly inside. A housing is mounted on the protective cover, and a transmission assembly is mounted on the housing. A bidirectional threaded rod is rotatably connected to the inner wall of the housing. By incorporating the buffer assembly, when the cable sways under wind force, the buffer assembly absorbs kinetic energy, significantly reducing the mechanical stress caused by excessive swaying, reducing wear and fatigue, lowering the probability of line faults, and ensuring a stable power supply. Through the inclusion of the transmission assembly, bidirectional threaded rod, nuts, connecting blocks, limiting blocks, and insulating rubber pads, the transmission assembly drives the bidirectional threaded rod to rotate, precisely controlling the proximity of a pair of nuts. This allows the limiting blocks to stably clamp the cable body, quickly fixing the cable and facilitating subsequent maintenance and repair. The insulating rubber pads ensure insulation and provide cushioning, preventing damage to the cable body.

Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically a wind-resistant high-voltage cable. Background Technology

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors, which can transmit electricity or information from one place to another. It is widely used in power transmission, communication and other fields. High voltage cables are cables suitable for transmitting electrical energy at voltage levels of 10kV and above, and are often used in high voltage transmission systems of urban power grids, large factories and other places.

[0003] The existing high-voltage cables still have the following shortcomings: the existing high-voltage cables have poor wind resistance. Wind force will cause the high-voltage cables to sway and vibrate, which will lead to problems such as cable wear and loose connections, resulting in power transmission interruption and affecting users' normal power use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a wind-resistant high-voltage cable, which solves the problem of poor wind resistance of existing high-voltage cables.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant high-voltage cable, including a protective cover, a buffer assembly inside the protective cover, a housing on the protective cover, a transmission assembly on the housing, a bidirectional threaded rod rotatably connected to the inner wall of the housing, a pair of nuts threadedly connected to the bidirectional threaded rod, a connecting block fixedly connected to each nut, a limit block fixedly connected to the top of the connecting block, and a cable body disposed between the pair of limit blocks.

[0006] As a further embodiment of this utility model: the buffer assembly includes a pair of limiting rods, each of the limiting rods is fixedly connected to the inner wall of the protective cover, each of the limiting rods is fitted with a pair of springs on its outer periphery, and each of the limiting rods is slidably connected to a sliding block on its outer periphery, with one side of the sliding block being fixedly connected to the housing.

[0007] As a further embodiment of this utility model: the transmission assembly includes a worm gear, which is rotatably connected to the housing. The worm gear has a telescopic hole, and a movable rod is slidably connected to the inner wall of the telescopic hole. A knob is coaxially fixedly connected to one end of the movable rod, and a worm wheel is coaxially fixedly connected to the bidirectional threaded rod. The worm wheel meshes with the worm gear.

[0008] As a further embodiment of this utility model, an insulating rubber pad is provided on the limiting block.

[0009] As a further embodiment of this utility model: the top of the protective cover is provided with a through groove one, which is adapted to the shell, and the top of the shell is provided with a through groove two, which is adapted to the connecting block.

[0010] As a further embodiment of this utility model: both sides of the protective cover are fixedly connected to mounting plates, and the mounting plates are provided with multiple mounting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up a buffer component, when the cable swings under the action of wind, the buffer component absorbs kinetic energy, which can greatly reduce the mechanical stress caused by excessive swinging of the cable, reduce wear and fatigue, reduce the probability of line faults, and ensure a stable power supply.

[0013] 2. This utility model, by setting up a transmission component, a bidirectional threaded rod, a nut, a connecting block, a limiting block, and an insulating rubber pad, allows the transmission component to drive the bidirectional threaded rod to rotate, which can precisely control a pair of nuts to approach each other, thereby allowing the limiting block to stably clamp the cable body, quickly fix the cable body, and facilitate subsequent maintenance and repair. The presence of the insulating rubber pad ensures insulation and provides cushioning to avoid damage to the cable body. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A wind-resistant high-voltage cable includes a protective cover 1, a buffer assembly inside the protective cover 1, a housing 2 on the protective cover 1, a transmission assembly on the housing 2, a bidirectional threaded rod 3 rotatably connected to the inner wall of the housing 2, a pair of nuts 4 threadedly connected to the bidirectional threaded rod 3, a connecting block 5 fixedly connected to each nut 4, a limit block 6 fixedly connected to the top of the connecting block 5, and a cable body 7 positioned between the pair of limit blocks 6. When the cable body 7 is placed between the pair of limit blocks 6, the transmission assembly drives the bidirectional threaded rod 3 to rotate, which can precisely control the pair of nuts 4 to move closer to each other. The nuts 4 drive the limit blocks 6 through the connecting block 5 to stably clamp the cable body 7, quickly fixing the cable body 7 and facilitating later maintenance and repair. When the cable body 7 swings under the action of wind, the buffer assembly absorbs kinetic energy, which can significantly reduce the mechanical stress caused by excessive swinging of the cable body 7, reduce wear and fatigue, reduce the probability of line faults, and ensure a stable power supply.

[0022] The buffer assembly includes a pair of limiting rods 8, each of which is fixedly connected to the inner wall of the protective cover 1. A pair of springs 9 are sleeved on the outer periphery of each limiting rod 8, and a sliding block 10 is slidably connected to the outer periphery of each limiting rod 8. One side of the sliding block 10 is fixedly connected to the housing 2. The cable body 7 drives the housing 2 to move, and the housing 2 drives the sliding block 10 to slide on the outer periphery of the limiting rod 8, so that the corresponding spring 9 is squeezed and the spring 9 is compressed.

[0023] The transmission assembly includes a worm gear 11, which is rotatably connected to the housing 2. The worm gear 11 has a telescopic hole 12, and a movable rod 13 is slidably connected to the inner wall of the telescopic hole 12. A knob 14 is coaxially fixedly connected to one end of the movable rod 13. A worm wheel 15 is coaxially fixedly connected to the bidirectional threaded rod 3. The worm wheel 15 meshes with the worm gear 11. The knob 14 drives the movable rod 13 to rotate, and the movable rod 13 drives the worm gear 11 to rotate. The worm gear 11 drives the bidirectional threaded rod 3 to rotate through the worm wheel 15 it meshes with. The movable rod 13 can slide and extend on the inner wall of the telescopic hole 12. When the movable rod 13 extends, it is convenient to apply force to the knob 14. When the movable rod 13 retracts, it is convenient to install the protective cover 1 with other structures.

[0024] An insulating rubber pad 16 is provided on the limiting block 6. The presence of the insulating rubber pad 16 not only ensures insulation but also provides cushioning to prevent damage to the cable body 7.

[0025] The protective cover 1 has a through groove 1 at the top, which is adapted to the housing 2. The housing 2 has a through groove 2 at the top, which is adapted to the connecting block 5. The housing 2 can move along the through groove 1, and the connecting block 5 can slide along the through groove 2 to prevent the connecting block 5 from rotating with the bidirectional threaded rod 3.

[0026] The protective cover 1 is fixedly connected to both sides of the mounting plate 17. The mounting plate 17 has multiple mounting holes. The protective cover 1 can be installed with other structures through the mounting holes on the mounting plates 17 on both sides.

[0027] The working principle of this utility model is as follows:

[0028] The cable body 7 is placed between a pair of limit blocks 6. The knob 14 drives the movable rod 13 to rotate, which drives the worm gear 11 to rotate. The worm gear 11 drives the bidirectional threaded rod 3 to rotate through the worm wheel 15 that meshes with it. The bidirectional threaded rod 3 can precisely control a pair of nuts 4 to move closer to each other. The nuts 4 drive the limit blocks 6 through the connecting block 5 to stably clamp the cable body 7, quickly fix the cable body 7, and facilitate later maintenance and repair.

[0029] When the cable body 7 swings under the action of wind, the cable body 7 drives the housing 2 to move. The housing 2 drives the sliding block 10 to slide around the limit rod 8, which causes the corresponding spring 9 to be squeezed. The spring 9 is compressed and absorbs kinetic energy, which can greatly reduce the mechanical stress caused by excessive swinging of the cable body 7, reduce wear and fatigue, reduce the probability of line faults, and ensure a stable power supply.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
