Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber sensing laying, in particular to a structure for increasing the vibration coupling degree of an optical fiber. Background Technique

[0002] In the current process of scientific and technological development, optical fiber sensing technology is playing an increasingly important role and is widely used in multiple key fields. Among them, in the detection of oil and gas pipeline leaks, optical fiber sensing can monitor the operating status of the pipeline in real time and accurately. Once a leak occurs, it can quickly issue an alarm, reducing safety risks and economic losses. In the field of subgrade settlement monitoring, optical fiber sensing, with its high precision and high stability, can promptly detect tiny changes in the subgrade, providing strong guarantee for the safety of infrastructure. In the scenario of monitoring vehicle flow and speed on the highway network, optical fiber sensing can efficiently obtain vehicle driving information, providing important data support for traffic management and planning. However, the laying method and coupling degree of the optical cable will have a significant impact on its sensing effect. Regarding the laying method of the optical cable, different laying environments and requirements require different methods. If the selection is improper, problems such as optical fiber damage and signal attenuation may occur, thereby reducing the accuracy and reliability of sensing.

[0003] In the existing technology, there are many problems in the actual application of traditional optical fiber co-groove laying and direct burial methods. On the one hand, the traditional co-groove laying and direct burial methods of optical cables and electric cables are highly random, greatly affected by the soil, and the coupling situation cannot be guaranteed. On the other hand, during the optical fiber laying process by construction personnel, there is a lack of unified operation specifications and quality control standards, which easily causes parameters such as the bending radius and tension of the optical cable to not meet the standards, affecting the performance of the optical fiber. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a structure for increasing the vibration coupling degree of an optical fiber, which can effectively solve the problems in the existing technology that the traditional co-groove laying and direct burial methods of optical cables and electric cables are highly random, greatly affected by the soil, and the coupling situation cannot be guaranteed. On the other hand, the quality of construction personnel varies, and the consistency of optical fiber laying is poor.

[0005] The technical solution adopted by the utility model is: a structure for increasing the vibration coupling degree of an optical fiber, including a base. A convex block is fixedly installed on the top of the base. An installation groove is opened on the top of the base. An installation block is fixedly installed inside the installation groove. A protection pad is fixedly installed on the top of the installation block. A armored optical fiber body is arranged on the top of the protection pad. A pressing block is arranged on the top of the base. A fixing block is fixedly installed at the bottom of the pressing block. A clamping groove is opened at the bottom of the fixing block. A second slot is opened inside the fixing block. A first plug is inserted and installed inside the second slot.

[0006] Preferably, the protection pad is located outside the protrusion, the protrusion and the protection pad have the same shape, and the cross-sections of both are "semi-circular" structures, and the protection pad is in contact with the armored optical fiber body.

[0007] Through the above technical solution and the design of the protective pad, when laying the optical fiber, the base can be placed at the optical fiber laying location first, and then the armored optical fiber body can be placed on the outside of the protective pad. This can prevent the armored optical fiber body from directly contacting the bump, which would easily cause damage to the armored optical fiber body when used for a long time.

[0008] Preferably, two identical protrusions, mounting grooves, mounting blocks and protective pads are provided, and the two protrusions, mounting grooves, mounting blocks and protective pads are symmetrically distributed about the center line of the base.

[0009] Through the above technical solution, through the design of two protrusions, mounting grooves, mounting blocks and protective pads, the two protrusions and the protective pad can form a circular groove, and the armored optical fiber body can be placed between the two, which can limit the armored optical fiber body and clamp the optical fiber in the circular protrusion to ensure the consistency of coupling.

[0010] Preferably, a slot 1 is provided on the top of the base, and plug blocks 2 are fixedly installed at the four corners of the pressure block. The plug block 2 and the slot 1 are plug-connected and correspond one to one.

[0011] Through the above technical solution, through the cooperation of plug block 2 and slot one, after the laying is completed, plug block 2 can be inserted into slot one, which can facilitate the rapid alignment of the base and the pressure block. The anti-foolproof design can avoid the reverse installation of the pressure block. At the same time, it can also facilitate the rapid installation of the base and the pressure block, reduce the difficulty of installation, and unify the operating specifications.

[0012] Preferably, the cross-sections of the pressing block and the fixing block are in a "T"-shaped structure, the cross-section of the clamping groove is in a "semicircular" structure, and the clamping groove is in contact with the top of the armored optical fiber body.

[0013] Through the above technical solution, through the design of the pressing block and the fixing block, when the armored optical fiber body is placed on the inner side of the two protrusions, the card slot can be in contact with the armored optical fiber body, and can be pressed against the top of the armored optical fiber body to form a fixed triangular structure with high stability.

[0014] Preferably, a compression sleeve is fixedly installed at the bottom of the insert block, a groove is opened on the outer side of the compression sleeve, the cross-sections of the compression sleeve and the groove are both "C"-shaped structures, and the compression sleeve and the groove are located on the top of the armored optical fiber body.

[0015] Through the above technical solution, through the design of the compression sleeve and the groove, during laying, the first insert block can also be inserted into the second slot. Subsequently, the compression sleeve is fixedly installed with the fixed block, enabling the compression sleeve to contact the armored optical fiber body, thereby playing a protective role for the armored optical fiber body and further improving its corrosion resistance and wear resistance.

[0016] Preferably, the same number of bases and pressing blocks are provided, and the bases and pressing blocks are made by cast-in-place technology or prefabrication technology.

[0017] Through the above technical solution, through the design of multiple bases and pressing blocks, since the cast-in-place technology and prefabrication technology of concrete involved in structural processing are very mature, it can be constructed in sections, increasing the coupling of the optical cable without increasing the maintenance difficulty. And if there is damage to the optical fiber, this section can be conveniently removed for fusion splicing repair, avoiding the relatively difficult later maintenance of the integral structure.

[0019] 1. For the structure for increasing the vibration coupling degree of an optical fiber, through the design of two convex blocks, the installation groove, the installation block and the protective pad, a circular groove can be formed by the two convex blocks and the protective pad, and the armored optical fiber body can be placed between the two, which can play a role in limiting the armored optical fiber body, clamping the optical fiber in the circular convex block, ensuring the consistency of coupling, and at the same time avoiding directly laying it on the soil, which is likely to cause a great influence on it by the soil and the coupling condition cannot be guaranteed.

[0020] 2. For the structure for increasing the vibration coupling degree of an optical fiber, through the cooperation of the second insert block and the first slot, after laying is completed, the second insert block can be inserted into the first slot, which is convenient for the bases and the pressing blocks to be quickly aligned, and at the same time enables the fixed block to clamp the armored optical fiber body, which can not only avoid the reverse installation of the pressing block, but also facilitate the quick installation of the bases and the pressing blocks, reduce the installation difficulty, unify the operation specifications and quality control standards, and avoid the parameters such as the bending radius and tension of the optical cable not meeting the standards and affecting the performance of the optical fiber.

[0021] 3.

[0035] Specifically, the cross-sections of the pressing block 8 and the fixing block 9 are in a "T"-shaped structure, and the cross-section of the card slot 10 is in a "semicircular" structure.

[0037] Specifically, there are the same number of bases 1 and pressing blocks 8. The bases 1 and pressing blocks 8 are made by cast-in-place technology or precast technology.

Through the design of the pressing sleeve 13 and the groove 14, during laying, the first inserting block 12 can also be inserted into the second slot 11, and then the pressing sleeve 13 is fixedly installed with the fixing block 9, so that the pressing sleeve 13 is in contact with the armored optical fiber body 6, thereby playing a role in protecting the armored optical fiber body 6, and can further improve its corrosion resistance and wear resistance. Through the design of multiple bases 1 and pressing blocks 8, since the cast-in-place technology and precast technology of concrete involved in structural processing are very mature, it can be constructed in sections, increasing the optical cable coupling without increasing the maintenance difficulty. And when there is damage to the optical fiber, this section can be easily removed for fusion splicing repair, avoiding the relatively difficult later maintenance of the integral structure.
