Description

Technical Field

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

[0002] The power line network for transmitting electric energy can be divided into two categories: "transmission network" and "distribution network". Generally, the lines with a system voltage of 220 kV and above are transmission lines (networks), and their main function is to realize the transmission and distribution of high-voltage electric energy with long distance and large capacity; the lines with a system voltage of 110 kV 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 further divided into three levels: high voltage (35 - 110 kV), medium voltage (6 - 20 kV), and low voltage (220 V / 380 V).

[0003] The transmission network is a point-to-point long-distance large-capacity backbone power line with few or no branch points. After completion, there are few opportunities for relocation and transformation. Its power poles are tall and mainly include overhead ground wires and overhead phase wires. The power system communication mainly uses optical fiber composite overhead ground wire optical cables (OPGW) multiplexed with overhead ground wires. In some lines with a voltage of 220 kV and below, all-dielectric self-supporting optical cables (ADSS) can be hung at appropriate positions on the poles. Currently, the fiber coverage rate of power communication nodes in the transmission network in China is higher than 95%.

[0004] The distribution network is an access network close to users. Its topological structure is different from the point-to-point mode of the transmission network. It has complex branches, numerous lead-down nodes, and is often upgraded and relocated. Among them, there are no overhead ground wires for medium and low voltage lines with a voltage of 63 kV and below, so there is no installation position for OPGW optical cables at this time. Although the voltage level of the distribution network is low, the types of poles are numerous, the height is low, the span is small, and there are many multi-circuits on the same tower (pole), and there is no suitable installation space for ADSS optical cables. The multiplexed optical fiber composite phase wire (OPPC) includes an outer power layer and an optical cable arranged inside the power layer. However, when the existing optical fiber composite phase wire 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-spliced later, but the splicing process is very difficult. Moreover, the existing optical cables are arranged in a mess inside the power layer, and it is easy to damage the optical cables during the construction of the power layer. To solve the above problems, an optical cable structure with a positioning function and a manufacturing method thereof are proposed in the present invention. Summary of the Invention

Detailed implementation manners

[0036] To make the objectives, 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 with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art in the field to which the present invention pertains. The words such as "including" used herein mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.

[0037] In view of the problems existing in the prior art, the embodiments of the present invention provide an optical cable structure with a positioning function, as Figure 1 shown. The optical cable structure with a positioning function includes an optical cable body 1 and a protective sleeve 3 wrapped outside the optical cable body 1. A first positioning mechanism 4 is sleeved outside the protective sleeve 3. The first positioning mechanism 4 is arranged in contact with a second positioning mechanism 5. The second positioning mechanism 5 is arranged on the inner side wall of the power layer 2. During installation, the protective sleeve 3 is provided to isolate the influence between the optical cable body 1 and the power layer 2 during construction. The mutual contact of the first positioning mechanism 4 and the second positioning mechanism 5 locks the length of the optical cable body 1 in the power layer 2 through the positioning effect.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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 abuts against the third positioning plate 51. The first positioning plate 411 is fixedly sleeved outside the protective sleeve 3. Thus, by changing the distance between the first positioning plate 411 and the second positioning plate 412, the relative positions of 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 left end of the optical cable body 1 extends too far outside the power layer 2, 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 by the first positioning plate 411 and the protective sleeve 3, thereby shortening the length of the optical cable body 1 extending outside the power layer 2; conversely, when the left end of the optical cable body 1 extends too little outside the power layer 2, the adjustment principle is the same as that in the case of being too long, and will not be elaborated here.

[0043] In one embodiment, as Figure 6 shown, the guiding and supporting assembly 413 includes a guiding support rod 4131, a guiding support cylinder 4132 and a guiding support spring 4133. The guiding support rod 4131 is movably inserted into the guiding support cylinder 4132. The guiding support spring 4133 is wound around the guiding support rod 4131, and both ends of the guiding support spring 4133 are fixedly connected to the side wall of the guiding support rod 4131 and the outer side wall of the guiding support cylinder 4132 respectively.

[0044] In this embodiment, the guiding and supporting assembly 413 is provided for two purposes. On the one hand, it is used for connecting the first positioning plate 411 and the second positioning plate 412. On the other hand, it can play a role of guiding and limiting 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 restoring force for the restoring movement of the second positioning plate 412.

[0045] In one embodiment, as Figure 3 and Figure 4 shown, the optical cable structure with positioning function further includes a limiting mechanism 6 provided between the positioning assembly 41 and the third positioning plate 51. The limiting mechanism 6 includes a limiting support rod 61 fixedly provided 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 into the limiting support groove 62. A second magnet block 64 is fixedly connected to the side wall of the limiting support groove 62. A first magnet block 63 abuts against the side wall of the second magnet block 64. The first magnet block 63 is fixedly provided on the limiting support rod 61. The magnetic poles of the mutually approaching sides of the first magnet block 63 and the second magnet block 64 are opposite. It should be noted that a second anti-card slot 65 is opened at one end of the first magnet block 63 facing.

[0046] In this embodiment, the setting of the limiting mechanism 6 can not only adsorb the second positioning plate 412 and the third positioning plate 51 more firmly, but also ensure that the horizontal central axis of the protective sleeve 3 coincides with the horizontal central axis of the power layer 2 during installation. Moreover, the setting of the limiting mechanism 6 can also reduce the difficulty of installing the guiding column 42 into the first through hole 52. Specifically, during installation, due to the 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, thus reducing the installation difficulty. And due to the 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 attached more firmly.

[0047] In actual setting, the number of the limiting mechanisms 6 is set to one, two, three or more. The specific setting can be determined according to the actual situation. Preferably, the number of the limiting mechanisms 6 is set to three, and the three limiting mechanisms 6 are arranged in an equidistant ring shape in the vertical direction.

[0048] In order to further efficiently align the limiting support rod 61 and the limiting support groove 62, in one embodiment, as Figure 4 shown, the limiting mechanism 6 further includes a third anti-card slot 66 opened at the notch end of the limiting support groove 62. The third anti-card slot 66 is opened on the third positioning plate 51. The first magnet block 63 is fixed at one end of the limiting support rod 61 located in the limiting support groove 62, and the first magnet block 63 has a round head structure (formed by the second anti-card slot 65). Among them, the cavity of the third anti-card slot 66 has a trumpet-shaped structure, and the size of the cavity opening of the third anti-card slot 66 is larger at the left end than at the right end. This can enable the limiting support rod 61 to quickly find the installation direction of the limiting support groove 62, and under the guidance of the groove wall of the third anti-card slot 66, the limiting support rod 61 can quickly, accurately and efficiently enter the limiting support groove 62.

[0049] In order to make the adjustment between the first positioning plate 411 and the second positioning plate 412 more convenient, in one embodiment, as Figure 5 and Figure 6As shown, the optical cable structure with positioning function further includes a first size adjustment mechanism 7. The first size adjustment mechanism 7 includes a first threaded rod 71 and a first threaded hole 72 formed in the first positioning plate 411. The first threaded rod 71 is threadedly inserted into the first threaded hole 72. One end of the first threaded rod 71 is fixedly connected to an adjustment disc 73. A screwing groove 74 is provided on the adjustment disc 73. The adjustment disc 73 is rotatably arranged on the first positioning plate 411. The other end of the first threaded rod 71 is fixedly connected to a second threaded rod 75. The second threaded rod 75 is threadedly inserted into an internal threaded tube 76. The internal threaded tube 76 is fixedly connected to the inner side wall of a fixed support tube 77. The fixed support tube 77 is fixedly arranged on the second positioning plate 412.

[0050] In this embodiment, the setting of the first size adjustment mechanism 7 can adjust the relative position between the first positioning plate 411 and the second positioning plate 412, so as to adjust the length of the optical cable body 1 outside the power layer 2. It should be understood that the setting of the first size adjustment mechanism 7 belongs to coarse adjustment. When it is necessary to change the length of the optical cable body 1 outside the power layer 2, rotate the combined structure of the adjustment disc 73 and the screwing groove 74. The rotation of the combined structure of the adjustment disc 73 and the screwing groove 74 will drive the rotation of the combined structure of the first threaded rod 71 and the second threaded rod 75. Since the second threaded rod 75 is movably inserted into the internal threaded tube 76, between the first positioning plate 411 and the second positioning plate 412, due to the limitation of the guiding and supporting component 413, it can only move in the horizontal direction. Therefore, the second positioning plate 412 is driven by the internal threaded tube 76 and the fixed support tube 77 to move closer to or away from the first positioning plate 411, so as to change the distance between the first positioning plate 411 and the second positioning plate 412.

[0051] When the length of the optical cable body 1 outside the power layer 2 is too long, it is necessary to cut the length of the optical cable body 1. 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, as Figure 7 shown, the optical cable structure with positioning function further includes a cutting and positioning mechanism 8. The cutting and positioning mechanism 8 includes a cutting and positioning rod 81 fixedly connected to the second positioning plate 412 and a second through hole 82 formed in the first positioning plate 411. The cutting and positioning rod 81 is movably inserted into the second through hole 82.

[0052] 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.

[0053] 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 Figure 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.

[0054] 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.

[0055] 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 Figure 10 As shown, the method is used to prepare the optical cable structure with positioning function, and the method comprises the following steps:

[0056] S1: Install the optical cable body 1 into the protective sleeve 3;

[0057] S2: The first positioning mechanism 4 is sleeved outside the protective sleeve 3;

[0058] S3: Install the second positioning mechanism 5 in the power layer 2;

[0059] 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;

[0060] 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;

[0061] 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 .

[0062] The beneficial effects of the present invention are as follows:

[0063] 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.

[0064] 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.
