Description

Technical Field

[0001] The present invention relates to the field of optical cable technology, and in particular to an optical cable structure with a positioning function and a manufacturing method thereof. Background Art

[0002] The power line network that transmits electric energy can be divided into two categories: "transmission network" and "distribution network". Usually, the lines with a system voltage of 220kV and above are transmission lines (networks), whose main function is to realize the transmission and distribution of large-capacity high-voltage electric energy over long distances; the lines with a system voltage of 110kV and below are distribution lines (networks). The distribution network is a network that draws out from a certain node in the transmission network and then distributes electric energy step by step. According to the voltage level, the distribution network can be divided into three levels: high voltage (35~110kV), medium voltage (6~20kV) and low voltage (220V / 380V).

[0003] The transmission network is a point-to-point long-distance large-capacity backbone power line with no branch points or few branch points. There are few opportunities for migration and reconstruction after construction. Its power towers are tall and mainly consist of two parts: overhead ground wire and overhead phase wire. The power system communication is mainly based on optical fiber composite overhead ground wire cable (OPGW) multiplexed with the overhead ground wire. In some 220kV and below lines, all-dielectric self-supporting optical cables (ADSS) can be hung at appropriate locations on the towers. At present, the optical fiber coverage rate of power communication nodes in my country's transmission network is higher than 95%.

[0004] The distribution network is an access network close to users. Its topology is different from the point-to-point mode of the transmission network. It has complex branches, numerous down-lead nodes, and is often upgraded and relocated. Among them, medium and low voltage lines of 63kV and below do not have overhead ground wires, so there is no installation location for OPGW optical cables. Although the voltage level of the distribution network is low, the poles and towers are of various types, low heights, and small spans. There are many multiple circuits on the same tower (pole), and there is no suitable installation space for ADSS optical cables. The multiplexed optical fiber composite phase line (OPPC) includes an outer power layer and an optical cable arranged inside the power layer. However, when the existing optical fiber composite phase line is manufactured, the length of the cable cannot be accurately controlled. If the reserved optical cable is too short, the optical cable needs to be re-welded later, but the welding process is very difficult, and the existing optical cables are arranged in the power layer in a disorderly manner. When the power layer is constructed, it is easy to cause damage to the optical cable. In order to solve the above problems, the present invention proposes a cable structure with positioning function and a manufacturing method thereof. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field of the present invention. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0020] In view of the problems existing in the prior art, an embodiment of the present invention provides an optical cable structure with a positioning function, such as Figure 1 As shown, the optical cable structure with positioning function includes an optical cable body 1, and a protective sleeve 3 wrapped around the optical cable body 1, a first positioning mechanism 4 is arranged outside the protective sleeve 3, the first positioning mechanism 4 and the second positioning mechanism 5 are arranged to conflict with each other, and the second positioning mechanism 5 is arranged on the inner wall of the power layer 2. During installation, the protective sleeve 3 is arranged to isolate the optical cable body 1 and the power layer 2 from affecting each other during construction, and the first positioning mechanism 4 and the second positioning mechanism 5 conflict with each other to lock the length of the optical cable body 1 in the power layer 2 through positioning.

[0021] The present invention provides a protective sleeve 3 outside the optical cable body 1. The provision of the protective sleeve 3 can isolate the optical cable body 1 and the power layer 2, so that when the optical cable body 1 or the power layer 2 is constructed, they will not affect each other, so during construction, the damage of the optical cable body 1 or the power layer 2 can be effectively prevented; the combined structure of the first positioning mechanism 4 and the second positioning mechanism 5 provided in the present invention can realize the positioning of the optical cable body 1 and the power layer 2 by mutual interference, thereby avoiding the reserved optical cable being too short during construction, and further effectively avoiding the subsequent step of re-fusing the optical cable.

[0022] In one embodiment, Figure 2 As shown, the second positioning mechanism 5 includes a third positioning plate 51 fixedly arranged on the inner wall of the power layer 2, and a first through hole 52 is opened in the middle of the third positioning plate 51. The first positioning mechanism 4 includes a positioning component 41 which is sleeved outside the protective cover 3 and contacts with the third positioning plate 51. The side wall of the positioning component 41 is fixedly connected with a guide column 42, and the guide column 42 is movably sleeved outside the protective cover 3. The guide column 42 is movably inserted in the first through hole 52, and a first anti-stuck groove 43 is opened at one end of the guide column 42 located in the first through hole 52.

[0023] In this embodiment, the combined structure of the second positioning mechanism 5 and the first positioning mechanism 4 are simply set, so that in the actual processing and preparation process, it can achieve the effect of saving time and labor. In addition, in this embodiment, the first through hole 52 is opened in the middle of the third positioning plate 51, so that the optical cable body 1 can be installed in the middle of the power layer 2 through the guide column 42, so that during construction, the distance between the optical cable body 1 and the power layer 2 can be made farther, which is more convenient for construction. Moreover, the setting of the first anti-stuck groove 43 in this embodiment can play an anti-stuck role, so that the process of installing the guide column 42 into the first through hole 52 can be more convenient and efficient.

[0024] In one embodiment, Figure 5 As shown, the positioning assembly 41 includes a first positioning plate 411 fixedly mounted on the outside of the protective cover 3, and a second positioning plate 412 movably mounted on the outside of the protective cover 3, and also includes a guide support assembly 413 arranged between the first positioning plate 411 and the second positioning plate 412 and used to connect the first positioning plate 411 and the second positioning plate 412, and the second positioning plate 412 is arranged to be in conflict with the third positioning plate 51.

[0025] In this embodiment, the first positioning plate 411 and the second positioning plate 412 can move relative to each other, and the second positioning plate 412 and the third positioning plate 51 are arranged to conflict with each other, and the first positioning plate 411 is fixedly sleeved outside the protective sleeve 3, so that by changing the distance between the first positioning plate 411 and the second positioning plate 412, the relative position between the optical cable body 1 and the power layer 2 will be changed through the third positioning plate 51 and the protective sleeve 3. For example, when the distance from the left end of the optical cable body 1 extending outside the power layer 2 is too long, the distance between the first positioning plate 411 and the second positioning plate 412 is reduced, so that the optical cable body 1 is retracted into the power layer 2 through the first positioning plate 411 and the protective sleeve 3, thereby shortening the length of the optical cable body 1 extending to the power layer 2; conversely, when the distance from the left end of the optical cable body 1 extending outside the power layer 2 is too short, the adjustment principle is consistent with that when it is too long, and it will not be repeated here.

[0026] In one embodiment, Figure 6 As shown, the guide support assembly 413 includes a guide support rod 4131, a guide support tube 4132 and a guide support spring 4133. The guide support rod 4131 is movably inserted in the guide support tube 4132, and the guide support spring 4133 is wound around the outside of the guide support rod 4131, and the two ends of the guide support spring 4133 are respectively fixedly connected to the side wall of the guide support rod 4131 and the outer side wall of the guide support tube 4132.

[0027] The setting of the guide support assembly 413 described in this embodiment is used for connecting the first positioning plate 411 and the second positioning plate 412 on the one hand, and can also play a guiding and limiting role for the movement of the second positioning plate 412, so that the second positioning plate 412 can only move in the horizontal direction. At the same time, it can also provide a reset force for the reset movement of the second positioning plate 412.

[0028] In one embodiment, Figure 3 and Figure 4 As shown, the optical cable structure with positioning function also includes a limiting mechanism 6 arranged between the positioning component 41 and the third positioning plate 51, the limiting mechanism 6 includes a limiting support rod 61 fixedly arranged on the second positioning plate 412, and a limiting support groove 62 opened on the third positioning plate 51, the limiting support rod 61 is movably inserted in the limiting support groove 62, and a second magnet block 64 is fixedly connected to the side wall of the limiting support groove 62, the side wall of the second magnet block 64 is abutted against the first magnet block 63, the first magnet block 63 is fixedly arranged on the limiting support rod 61, and the magnetic poles of the first magnet block 63 and the second magnet block 64 are opposite to each other. It should be noted that the first magnet block 63 is provided with a second anti-stuck groove 65 toward one end.

[0029] The setting of the limiting mechanism 6 in this embodiment can not only adsorb the second positioning plate 412 and the third positioning plate 51 more firmly, but also ensure that the horizontal center axis of the protective cover 3 coincides with the horizontal center axis of the power layer 2 during installation. Moreover, the setting of the limiting mechanism 6 can also reduce the difficulty of installing the guide column 42 into the first through hole 52. Specifically, during installation, due to the mutual attraction between the first magnet block 63 and the second magnet block 64, there is no need to accurately align the limiting support rod 61 and the limiting support groove 62, thereby reducing the difficulty of installation. Moreover, due to the mutual attraction between the first magnet block 63 and the second magnet block 64, the second positioning plate 412 and the third positioning plate 51 can be more firmly attached.

[0030] In actual settings, the number of the limiting mechanisms 6 is set to one, two, three or more, and the specific settings can be determined according to actual conditions; preferably, the number of the limiting mechanisms 6 is set to three, and the three limiting mechanisms 6 are arranged in an equidistant ring in the vertical direction.

[0031] In order to further efficiently make the limiting support rod 61 and the limiting support groove 62, in one embodiment, as Figure 4 As shown, the limiting mechanism 6 also includes a third anti-stuck groove 66 provided at the slot end of the limiting support groove 62, the third anti-stuck groove 66 is provided on the third positioning plate 51, the first magnet block 63 is fixed to one end of the limiting support rod 61 located in the limiting support groove 62, and the first magnet block 63 is in a round head structure (formed by the second anti-stuck groove 65). Among them, the slot cavity of the third anti-stuck groove 66 is in a trumpet-shaped structure, and the size of the slot cavity opening of the third anti-stuck groove 66 is larger at the left end than at the right end, so that the limiting support rod 61 can quickly find the installation direction of the limiting support groove 62, and under the guidance of the slot wall of the third anti-stuck groove 66, the limiting support rod 61 can quickly, accurately and efficiently enter the limiting support groove 62.

[0032] In order to facilitate the adjustment between the first positioning plate 411 and the second positioning plate 412, in one embodiment, Figure 5 and Figure 6As shown, the optical cable structure with positioning function also includes a first size adjustment mechanism 7, which includes a first threaded rod 71 and a first threaded hole 72 opened on the first positioning plate 411, the first threaded rod 71 is threadedly inserted in the first threaded hole 72, one end of the first threaded rod 71 is fixedly connected with an adjustment disk 73, the adjustment disk 73 is provided with a screwing groove 74, the adjustment disk 73 is rotatably set on the first positioning plate 411, the other end of the first threaded rod 71 is fixedly connected with a second threaded rod 75, the second threaded rod 75 is threadedly inserted in an internal threaded tube 76, the internal threaded tube 76 is fixedly connected to the inner side wall of the fixed support tube 77, and the fixed support tube 77 is fixedly set on the second positioning plate 412.

[0033] The first size adjustment mechanism 7 in this embodiment can adjust the relative position between the first positioning plate 411 and the second positioning plate 412, thereby adjusting the length of the optical cable body 1 outside the power layer 2. It should be understood that the first size adjustment mechanism 7 is a rough adjustment. When the length of the optical cable body 1 outside the power layer 2 needs to be changed, the combination structure of the adjustment disk 73 and the screwing groove 74 is screwed. The rotation of the combination structure of the adjustment disk 73 and the screwing groove 74 will lead to the rotation of the combination structure of the first threaded rod 71 and the second threaded rod 75. Since the second threaded rod 75 is movably inserted in the internal threaded tube 76, between the first positioning plate 411 and the second positioning plate 412, due to the limitation of the guide support assembly 413, it can only move in the horizontal direction. Therefore, the second positioning plate 412 is moved closer to or away from the first positioning plate 411 through the internal threaded tube 76 and the fixed support tube 77, thereby changing the distance between the first positioning plate 411 and the second positioning plate 412.

[0034] When the length of the optical cable body 1 outside the power layer 2 is too long, the length of the optical cable body 1 needs to be cut. In order to ensure that the length of the optical cable body 1 outside the power layer 2 after cutting is within the standard range, in one embodiment, Figure 7 As shown, the optical cable structure with positioning function also includes a cutting positioning mechanism 8, which includes a cutting positioning rod 81 fixedly connected to the second positioning plate 412, and a second through hole 82 opened on the first positioning plate 411, and the cutting positioning rod 81 is movably inserted in the second through hole 82.

[0035] The length of the cutting positioning rod 81 in this embodiment is the standard range length of the optical cable body 1 outside the power layer 2, and the standard length can be adjusted according to the actual situation. In addition, the structural design of the cutting positioning mechanism 8 in this embodiment is reasonable, and the cutting positioning rod 81 is movably plugged into the first positioning plate 411 and fixedly connected to the second positioning plate 412, so that when the distance between the first positioning plate 411 and the second positioning plate 412 is adjusted, the cutting positioning rod 81 will also be driven to move relative to the power layer 2, so that when the optical cable body 1 is cut, it is more accurate, and the left end of the cutting positioning rod 81 is used as a benchmark, which can make the cutting process more convenient.

[0036] When the length of the optical cable body 1 outside the power layer 2 is too long, the optical cable body 1 needs to be cut. In order to make the cutting process more accurate, in one embodiment, Figure 8 and Fig. 9 As shown, the optical cable structure with positioning function also includes a flush ring 9 arranged outside the cutting positioning rod 81, and also includes a second size adjustment mechanism 10, the second size adjustment mechanism 10 includes a second threaded hole 101 and a third through hole 103 opened on the flush ring 9 and connected to each other, the cutting positioning rod 81 is movably inserted in the third through hole 103, and the third threaded rod 102 is threadedly inserted in the second threaded hole 101, the upper end of the third threaded rod 102 can extend into the third through hole 103 and is arranged to conflict with the cutting positioning rod 81, and the cutting positioning rod 81 is provided with a scale line 104.

[0037] In this embodiment, the flush ring 9 is arranged vertically, so that the left side of the flush ring 9 is used as a standard edge, and the optical cable body 1 can be cut more smoothly in the vertical direction. Moreover, in this example, the flush ring 9 can move on the cutting positioning rod 81, and the second size adjustment mechanism 10 is also provided with a scale line 104 on the cutting positioning rod 81, so that the length of the optical cable body 1 can be cut more accurately. At the same time, after the position of the flush ring 9 on the cutting positioning rod 81 is adjusted, the third threaded rod 102 is screwed, and the upper end of the third threaded rod 102 is used to resist the cutting positioning rod 81, so that the position of the cutting positioning rod 81 and the flush ring 9 can be locked, thereby avoiding relative movement between the flush ring 9 and the optical cable body 1 during cutting.

[0038] In view of the problems existing in the prior art, the embodiments of the present invention further provide a method for manufacturing an optical cable structure with a positioning function, such as Fig.10 As shown, the method is used to prepare the optical cable structure with positioning function, and the method comprises the following steps: S1: Install the optical cable body 1 into the protective sleeve 3; S2: The first positioning mechanism 4 is sleeved outside the protective sleeve 3; S3: Install the second positioning mechanism 5 in the power layer 2; S4: Install the optical cable body 1 with the protective cover 3 and the first positioning mechanism 4 installed outside into the power layer 2 until the first positioning mechanism 4 and the second positioning mechanism 5 come into contact with each other and stop; S5: driving the first size adjustment mechanism 7 to roughly adjust the relative position between the optical cable body 1 and the power layer 2 through the distance between the first positioning plate 411 and the third positioning plate 51; S6: driving the second size adjustment mechanism 10 to precisely adjust the relative position between the optical cable body 1 and the power layer 2 by changing the position of the flush ring 9 on the optical cable body 1 .

[0039] The beneficial effects of the present invention are as follows: The present invention provides a protective sleeve 3 outside the optical cable body 1. The provision of the protective sleeve 3 can isolate the optical cable body 1 and the power layer 2, so that when the optical cable body 1 or the power layer 2 is constructed, they will not affect each other, so during construction, the damage of the optical cable body 1 or the power layer 2 can be effectively prevented; the combined structure of the first positioning mechanism 4 and the second positioning mechanism 5 provided in the present invention can realize the positioning of the optical cable body 1 and the power layer 2 by mutual interference, thereby avoiding the reserved optical cable being too short during construction, and further effectively avoiding the subsequent step of re-fusing the optical cable.

[0040] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
