Description

Technical Field

[0001] This utility model relates to the field of overhead cable technology, and in particular to an overhead insulated cable. Background Technology

[0002] Overhead cables are a type of high-voltage transmission line, typically composed of conductors, supports, and insulators. They are characterized by conductors made of materials such as aluminum alloy and copper, and transmit power by being suspended from utility poles. Overhead cables are widely used in urban and rural power transmission and distribution systems, offering advantages such as high transmission capacity, low line investment, and convenient maintenance and management.

[0003] Chinese utility model patent application number CN202120980721.9 discloses an overhead insulated cable. This cable features a clamp body that holds the cable body within a circular groove formed between an upper and lower clamping plate. This effectively organizes the cable body, preventing it from becoming tangled and difficult to distinguish. Furthermore, during maintenance, personnel only need to remove the set bolts to separate the upper and lower clamping plates for cable inspection, reducing maintenance time and effort, minimizing the time spent working at heights, reducing safety hazards, and increasing safety.

[0004] However, the main structure of the clamp is relatively fixed, making it difficult to adapt to the cable layout requirements in different scenarios. For example, when passing through narrow spaces, around buildings, or obstacles, the cable spacing cannot be adjusted, resulting in poor applicability. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an overhead insulated cable to solve the technical problem that overhead insulated cables are difficult to adapt to the cable layout requirements in different scenarios, such as when passing through narrow spaces, around buildings or obstacles, the cable spacing cannot be adjusted, resulting in poor applicability.

[0006] This utility model provides an overhead insulated cable, including two cable bodies, and further comprising:

[0007] Two fixing components, each of which includes a symmetrically arranged upper clamping plate and a lower clamping plate and a locking member. One side of the upper clamping plate and the lower clamping plate is rotatably connected to a hinge hole, and the opposite side is operably close to each other to form a circular tubular structure that is adapted to the surface shape of the cable body. The locking member is used to lock the opposite side of the upper clamping plate and the lower clamping plate.

[0008] An adjustment component is disposed between the two lower clamping plates to synchronously move the two fixed components closer or further apart, thereby adjusting the distance between the two cable bodies.

[0009] Furthermore, the adjustment assembly includes a bidirectional screw arranged along its axis and two moving blocks threadedly connected to the bidirectional screw, the two moving blocks being respectively connected to two lower clamping plates.

[0010] Furthermore, an operating part is provided in the middle of the bidirectional screw, and the operating part is provided with a plurality of anti-slip textures and / or anti-slip grooves.

[0011] Furthermore, limiting portions are provided at both opposite ends of the bidirectional screw.

[0012] Furthermore, both the upper clamping plate and the lower clamping plate include a semi-circular arc-shaped clamping portion and a fastening portion formed radially on the side of the clamping portion away from the hinge hole. The two fastening portions correspond to each other, and the upper clamping plate and the lower clamping plate are connected by a locking member through the corresponding two fastening portions. The moving block is connected to the fastening portion of the lower clamping plate.

[0013] Furthermore, the locking component includes a T-bolt, with straight slots provided on both fastening parts, and one end of the straight slot having a notch; the bolt head of the T-bolt is movably disposed in the straight slot of the upper clamping plate, and the bolt shank of the T-bolt is operably positioned in the straight slot of the lower clamping plate through the notch, and fixed in the straight slot by a nut, so that the upper and lower clamping plates are tightly fitted with the cable body.

[0014] Furthermore, a groove is provided on the fastening part of the lower clamping plate, and the nut is installed in the groove.

[0015] Furthermore, the inner walls of both the upper clamping plate and the lower clamping plate are provided with mounting grooves, and the inner walls of the mounting grooves are provided with anti-slip pads. The anti-slip pads and the mounting grooves with the anti-slip pads are in close contact with the outer wall of the cable body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In use, the overhead insulated cable of this utility model first fixes one fixing component to one cable body, and then fixes another fixing component to another cable body. Subsequently, the two fixing components can be adjusted to move closer or further apart, thereby changing the distance between the two fixing components and thus changing the distance between the two cable bodies. Therefore, it can adapt to the cable layout requirements in different scenarios, such as when passing through narrow spaces, around buildings, or obstacles, avoiding mutual interference, thus increasing applicability.

It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0029] like Figure 1-4As shown, an embodiment of this utility model provides an overhead insulated cable, including two cable bodies 10, two fixing components 20, and an adjusting component 30. Each fixing component 20 includes an upper clamping plate 21 and a lower clamping plate 22 symmetrically arranged, and a locking member 23. One side of the upper clamping plate 21 and the lower clamping plate 22 is rotatably connected to a hinge hole, and the opposite side is operably close to each other to form a circular tubular structure that matches the surface shape of the surface in contact with the cable body 10. The locking member 23 is used to lock the opposite side of the upper clamping plate 21 and the lower clamping plate 22. The adjusting component 30 is disposed between the two lower clamping plates 22 and is used to synchronously move the two fixing components 20 closer or further apart to adjust the distance between the two cable bodies 10.

[0030] In this embodiment of the utility model, during use, one fixing component 20 is first fixed to one cable body 10, and then another fixing component 20 is fixed to another cable body 10. Subsequently, the two fixing components 20 can be moved closer or further apart by adjusting the component 30, thereby changing the distance between the two fixing components 20, and thus changing the distance between the two cable bodies 10. Therefore, it can adapt to the cable layout requirements in different scenarios, such as when passing through narrow spaces, around buildings or obstacles, avoiding mutual interference, thereby increasing applicability.

[0031] Specifically, such as Figure 2 As shown in this embodiment of the present invention, the adjusting component 30 includes a bidirectional screw 31 arranged along its axis and two moving blocks 32 threadedly connected to the bidirectional screw 31. The two moving blocks 32 are respectively connected to two lower clamping plates 22. When the bidirectional screw 31 is rotated, since the threads are opposite, the two moving blocks 32 will move towards each other or away from each other according to the rotation direction, thereby driving the two fixed components 20 to move closer or further away from each other, thereby adjusting the cable spacing. In order to avoid slippage when operating the bidirectional screw 31 and affecting the operation, an operating part 311 is provided in the middle of the bidirectional screw 31. The operating part 311 is provided with several anti-slip patterns and / or anti-slip grooves. At the same time, a limiting part 312 is provided at both opposite ends of the bidirectional screw 31 to limit the fixed components 20 and prevent the fixed components 20 from detaching from the bidirectional screw 31 due to over-adjustment.

[0032] Specifically, such as Figure 3-4As shown in the embodiment of this utility model, both the upper clamping plate 21 and the lower clamping plate 22 include a semi-circular arc-shaped clamping portion 211 and a fastening portion 212 disposed on the side of the clamping portion 211 away from the hinge hole and formed in its radial direction. The two fastening portions 212 correspond to each other, and the upper clamping plate 21 and the lower clamping plate 22 are connected by a locking member 23 through the corresponding two fastening portions 212; the moving block 32 is connected to the fastening portion 212 of the lower clamping plate 22.

[0033] When it is necessary to install or adjust the cable, the operator can open the upper clamp 21, put the cable body 10 into the semi-circular space formed by the clamping part 211, and then close the upper clamp 21. Then, the fastening part 212 of the upper clamp 21 and the lower clamp 22 are connected and locked by the locking member 23, so that the cable is firmly fixed in the middle.

[0034] Specifically, such as Figure 3-4 As shown in this embodiment of the present invention, the locking member 23 includes a T-bolt 231. Both fastening parts 212 are provided with straight slots 232, and one end of the straight slot 232 has a notch 233. The bolt head of the T-bolt 231 is movably disposed in the straight slot 232 of the upper clamping plate 21, and the bolt shank of the T-bolt 231 is operablely disposed in the straight slot 232 of the lower clamping plate 22 through the notch 233, and is fixed in the straight slot 232 by a nut 234, so that the upper clamping plate 21 and the lower clamping plate 22 are tightly fitted with the cable body 10. In order to make the connection between the two fastening parts 212 more stable, two straight slots 232 are provided on the same fastening part 212, and are symmetrically arranged on both sides of the fastening part 212. Correspondingly, there are also two T-bolts 231 and nuts 234 in each straight slot 232.

[0035] In use, first unscrew the nut 234 from the T-bolt 231. At this point, the two clamping parts 211 can be separated. Then, put the two clamping parts 211 on the cable body 10 and make the two fastening parts 212 correspond to each other. After that, screw the nut 234 back onto the T-bolt 231 until both clamping parts 211 are in contact with the cable body 10, thereby completing the installation of the cable body 10.

[0036] Based on the above solutions, such as Figure 3-4As shown in this embodiment of the present invention, a groove 235 is provided on the fastening part 212 of the lower clamping plate 22, and the nut 234 is installed in the groove 235. When the nut 234 is tightened on the upper T-bolt 231, the nut 234 is installed in the groove 235 to connect and lock the fastening parts 212 of the upper clamping plate 21 and the lower clamping plate 22. At this time, the nut 234 is hidden in the groove 235 and does not protrude from the fastening part 212, which can avoid the nut 234 from loosening due to misoperation and external factors, thereby loosening the entire cable body 10.

[0037] Based on the above solution, in one embodiment of this utility model, the inner walls of the upper clamping plate 21 and the lower clamping plate 22 are both provided with mounting grooves, and the inner walls of the mounting grooves are provided with anti-slip pads. The anti-slip pads and the mounting grooves with the anti-slip pads are tightly fitted with the outer wall of the cable body 10, thereby preventing the cable body 10 from rotating and improving its stability. In addition, to make it more stable, the anti-slip pads can be double-layered, and the anti-slip pads can be made of anti-static silicone material.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
