Description

Temperature-sensing optical cable installation components and their installation process

[0001] This application claims priority to Chinese Patent Application No. 202411745247.6, filed on December 2, 2024, entitled "A Temperature-Sensing Optical Cable Installation Assembly and its Installation Process", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of optical cable installation technology, and in particular relates to a temperature-sensing optical cable installation component and its installation process. Background Technology

[0003] Fiber optic temperature sensing technology is an advanced temperature sensing technology with real-time, online, and multi-point temperature measurement capabilities. This technology uses a special medium called a temperature-sensing optical cable to combine the functions of a sensor and a signal transmission channel. It converts the temperature information of the space where the optical fiber is located into a backscattered light signal, which is then mediated, acquired, and processed to achieve real-time display of the temperature information.

[0004] In the field of fire detection, fiber optic temperature sensing technology has great application value due to its multi-point real-time detection characteristics. For example, in tunnel engineering, by laying temperature sensing optical cables along the tunnel, temperature data at various points in the tunnel can be collected in real time, providing accurate temperature information for fire early warning systems.

[0005] However, in the actual installation of temperature-sensing optical cables, due to the lack of unified installation standards and standardized installation processes, construction workers mainly rely on their own experience to lay the cables, which leads to inconsistent installation methods and frequent problems.

[0006] The two main installation methods currently used, cable tray installation and suspended installation, each have obvious drawbacks:

[0007] 1. Cable Tray Installation: In this method, the temperature-sensing optical cable is laid inside the cable tray. However, because the cable tray is used for both cable laying and maintenance, the temperature-sensing optical cable is susceptible to mechanical damage, leading to performance degradation. Furthermore, the lack of tensioning measures within the cable tray means that when the cable is laid over a long distance, there may be significant discrepancies between the temperature measurement and the actual location, causing the fire alarm system to fail to accurately locate the fire source and thus delaying rescue efforts.

[0008] 2. Suspension Installation: This method involves suspending the temperature-sensing optical cable with steel wires. The steel wires must first be suspended, secured, and tensioned before the optical cable can be suspended. This method not only involves complex construction procedures and a significant increase in safety risks due to extensive high-altitude work, but also results in a higher economic burden due to the higher material and labor costs. Summary of the Invention

[0009] In view of the shortcomings of the related technologies, this application provides a temperature-sensing optical cable installation component and its installation process to solve the problems of easy damage, lack of tension, complex procedures and high cost of the current temperature-sensing optical cable installation method.

[0034] In some embodiments, a guide post is mounted on the base, and the compression spring is sleeved on the guide post.

[0035] A third aspect of this application provides a temperature-sensing optical cable installation process, employing the temperature-sensing optical cable installation assembly as described in either the first or second aspect, comprising the following steps:

[0036] S10: Move the first fixing plate of each of the temperature-sensing optical cable installation assemblies to the second fixing plate for the first time, and fix each of the first fixing plates when the moving distance reaches the first set distance L1.

[0037] S20: Install a first temperature-sensing optical cable installation assembly on the top plate at the front end of the tunnel, lift the winch with the temperature-sensing optical cable wound around it to the rear side of the first temperature-sensing optical cable installation assembly, pull one end of the temperature-sensing optical cable from the winch, and clamp and fix it between the first fixing plate and the second fixing plate of the first temperature-sensing optical cable installation assembly.

[0038] S30: Move the winch backward, install a second temperature-sensitive optical cable installation assembly on the tunnel roof adjacent to the front side of the winch, clamp and fix the temperature-sensitive optical cable pulled out as the winch moves backward between the first fixing plate and the second fixing plate of the second temperature-sensitive optical cable installation assembly, connect the temperature-sensitive optical cable on the rear side of the second temperature-sensitive optical cable installation assembly to a tension gauge, and pull the tension gauge horizontally backward until its tension value reaches the set tension F, so that the temperature-sensitive optical cable between the second temperature-sensitive optical cable installation assembly and the first temperature-sensitive optical cable installation assembly is tightened; move the winch backward sequentially in the aforementioned manner, each... After the winch is moved horizontally, a temperature-sensing optical cable installation assembly is installed on the tunnel roof adjacent to its front side. The pulled-out temperature-sensing optical cable is clamped and fixed on the newly installed temperature-sensing installation assembly. A tension gauge is connected to the temperature-sensing optical cable on the rear side of the newly installed temperature-sensing installation assembly and pulled horizontally backward until its tension value reaches the set tension F, so that the temperature-sensing optical cable between the newly installed temperature-sensing installation assembly and the adjacent temperature-sensing optical cable installation assembly on the front side is tightened until the temperature-sensing installation assembly is installed on the roof of the tunnel rear end, and all the installed temperature-sensing optical cable installation assemblies are aligned on the same horizontal line.

[0039] S40: Move the first fixing plate of each of the temperature-sensing optical cable installation assemblies from front to back to the second fixing plate for the second time. When the moving distance reaches the second set distance L2, fix the first fixing plate. When the number of temperature-sensing optical cable installation assemblies that have completed the second movement reaches 40% of the total number of temperature-sensing optical cable installation assemblies, install a limiting clamp on the temperature-sensing optical cable behind each temperature-sensing optical cable that has not undergone the second movement. The limiting clamp is attached to the adjacent temperature-sensing optical cable installation assembly on the front side.

[0040] S50: For the temperature-sensing optical cable installation components that have not been moved a second time, move the first fixing plate to the second fixing plate one by one from front to back. When the moving distance reaches the second set distance L2, fix the first fixing plate.

[0041] In some embodiments, the first predetermined distance

[0042] The second set distance

[0043] The set tension F = c × F max ;

[0044] In the above formula, a is 80%, b is 90%, c is 85%, and F... max denoted as , where is the tensile strength of the temperature-sensing optical cable, D is the mean diameter of the compression spring, n is the effective number of turns of the compression spring, G is the shear modulus of the material used for the compression spring, d is the diameter of the compression spring wire, and μ is the coefficient of friction between the outer sheath of the temperature-sensing optical cable and the rubber pad.

[0045] In some embodiments, the spacing between adjacent temperature-sensing optical cable mounting assemblies is less than a predetermined spacing L3.

[0046] Where q is the weight of one meter of temperature-sensing optical cable.

[0047] In some embodiments, the temperature-sensing optical cable installation assembly is installed onto a leveling pad provided on the tunnel roof, and each of the temperature-sensing optical cable installation assemblies is installed at the same height and aligned with each other in the front-to-back direction.

[0048] In some embodiments, during step S40, when installing the limiting clamps, they are installed one by one from back to front.

[0049] In some embodiments, when the temperature-sensing optical cable mounting assembly is installed onto the tunnel roof, the temperature-sensing optical cable mounting assembly is installed upside down, with the second fixing plate placed above the first fixing plate, and the base fixedly connected to the tunnel roof.

[0050] In some embodiments, in step S50, each time a second movement of one of the temperature-sensing optical cable installation assemblies is completed, that is, one of the adjacent limiting clamps on the rear side is removed.

[0051] Compared with the prior art, the beneficial effects of this application are as follows: In the embodiments of this application, the temperature-sensing optical cable installation assembly installed on the building structure is used to clamp and fix the temperature-sensing optical cable, thereby realizing the installation of the temperature-sensing optical cable. The process is simple, easy to operate, and low in cost. Moreover, the clamping and fixing of the temperature-sensing optical cable can maintain its tension after installation, keeping the temperature-sensing optical cable in a straight state. The correspondence between the measured temperature and position is accurate. The temperature-sensing optical cable is installed separately outside the cable tray and will not be damaged. This solves the problems of easy damage, lack of tension, complex process, and high cost of the current temperature-sensing optical cable installation method. Attached Figure Description

[0068] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0069] In the description of this application, it should be understood that the terms "center," "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, the descriptions of orientations such as "front end," "rear end," "front side," and "rear side" are based on the installation direction of the temperature-sensing optical cable.

[0070] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0071] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0072] As shown in Figures 1 and 2, in one schematic embodiment of the temperature-sensing optical cable installation assembly of this application, the temperature-sensing optical cable installation assembly includes a base 1, a support plate 2, a first fixing plate 3, a second fixing plate 4, and a compression spring 5.

[0073] One side surface of the base 1 serves as the mounting surface 101. The support plate 2 and one end of the compression spring 5 are both fixedly mounted on the mounting surface 101. The first fixing plate 3 is mounted on the support plate 2 via fixing bolts 6. The second fixing plate 4 is located between the first fixing plate 3 and the base 1 and is fixedly connected to the other end of the compression spring 5. Multiple fixing bolts 6 are located in the adjustment holes 7 provided on the support plate 2. The adjustment holes 7 are oblong holes and parallel to the axial direction of the compression spring 5. Rubber pads 8 are mounted on the surfaces of both the first fixing plate 3 and the second fixing plate 4, with the two rubber pads 8 positioned opposite each other.

[0074] The adjusting hole 7 is designed as a waist hole, giving it an extended length, and the length direction of the adjusting hole 7 is parallel to the axis of the compression spring 5. The position of the first fixing plate 3 on the support plate 2 is adjusted by adjusting the position of the fixing bolt 6 in the adjusting hole 7.

[0075] It is understandable that the second fixing plate 4 is connected to the mounting surface 101 of the base 1 by a compression spring 5, and there is no fixed connection between it and the support plate 2, so the position of the second fixing plate 4 relative to the support plate 2 can be changed.

[0076] In some embodiments, when the fixing bolt 6 is attached to the end of the adjusting hole 7 away from the base 1, the compression spring 5 is in a non-elastic deformation state, and both rubber pads 8 are attached to the temperature-sensing optical cable 100 between them. At this time, the temperature-sensing optical cable mounting assembly 200 is in its initial state, the elastic deformation of the compression spring 5 is 0, and the two rubber pads 8 are just attached to both sides of the temperature-sensing optical cable.

[0077] It is understandable that, in the above initial state, "the fixing bolt 6 is attached to the end of the adjusting hole 7 away from the base 1" means that the fixing bolt 6 that is farthest from the second fixing plate 4 among the multiple fixing bolts 6 is attached to the end of the adjusting hole 7 away from the base 1, as shown in Figure 4.

[0078] Loosen all the fixing bolts 6, allowing them to slide along the adjusting holes 7 towards the second fixing plate 4, bringing the first fixing plate 3 closer to the second fixing plate 4. Then tighten the fixing bolts 6 to fix the first fixing plate 3 in a position even closer to the second fixing plate 4. At this time, the temperature-sensing optical cable installation assembly 200 is in working condition. The two rubber pads 8 are respectively attached to both sides of the temperature-sensing optical cable 100, and the compression spring 5 is compressed. The resulting elastic force acts on the second fixing plate 4, causing the first fixing plate 3 and the second fixing plate 4 to clamp and fix the temperature-sensing optical cable between them through the two rubber pads 8.

[0079] Adjust the temperature-sensing optical cable installation assembly 200 to the working state and fix it on the building structure. The base 1 is fixedly connected to the building structure. Lay the temperature-sensing optical cable 100 and clamp and fix it to each temperature-sensing optical cable installation assembly 200, thereby realizing the laying and installation of the temperature-sensing optical cable 100.

[0080] The temperature-sensing optical cable mounting assembly 200 is typically installed inverted during use, with the base 1 at the top, placing the second fixing plate 4 above the first fixing plate 3. The temperature-sensing optical cable 100 is located between the second fixing plate 4 and the first fixing plate 3, and a compression spring 5 connects the second fixing plate 4 and the base 1. The temperature-sensing optical cable mounting assembly 200 includes an initial state and an operating state. By adjusting the position of the fixing bolt 6 in the adjusting hole 7, the position of the first fixing plate 3 is changed, allowing the temperature-sensing optical cable mounting assembly 200 to be in either the initial or operating state.

[0081] As shown in Figures 3 and 4, when the temperature-sensing optical cable installation assembly 200 is in its initial state, the first fixing plate 3 is fixed to the first position on the support plate. At this time, the compression spring 5 is in a non-elastic deformation state.

[0082] In the initial state, assuming the compression spring 5 is in a non-elastic deformation state, the second fixing plate 4 and the temperature-sensing optical cable 100 are supported by the first fixing plate 3. The second fixing plate 4 is mainly used to provide a clamping surface in conjunction with the first fixing plate 3. To avoid the weight of the second fixing plate 4 affecting the pressure control acting on the temperature-sensing optical cable 100, the second fixing plate 4 can be made of a lightweight material, such as foam, so its influence can be ignored.

[0083] Optionally, in the first position, the fixing bolt 6 furthest from the second fixing plate 4 among the plurality of fixing bolts 6 is attached to the end of the adjusting hole 7 furthest from the base 1.

[0084] As shown in Figures 5 and 6, when the temperature-sensing optical cable mounting assembly 200 is in operation, the first fixing plate 3 is fixed to a second position on the support plate 2, which is closer to the base 1 than the first position, and the compression spring 5 is compressed. As the first fixing plate 3 moves closer to the base 1, it pushes the temperature-sensing optical cable 100 and the second fixing plate 4 to move closer to the base 1, causing the compression spring 5 to be compressed. The elastic restoring force generated by the compression spring 5 acts on the second fixing plate 4, so that the second fixing plate 4 and the first fixing plate 1 form a clamping force on the temperature-sensing optical cable 100 located between them.

[0085] Understandably, in the working state, the second position of the first fixing plate 3 is not a fixed position, but includes multiple different positions located near the second fixing plate 4 on the side of the first position, specifically determined according to the required clamping force on the temperature-sensing optical cable 100. The temperature-sensing optical cable installation assembly 200 is adjusted to the working state and fixed to the building structure. The base 1 is fixedly connected to the building structure. The temperature-sensing optical cable 100 is then laid and clamped and fixed to each temperature-sensing optical cable installation assembly 200, thereby realizing the laying and installation of the temperature-sensing optical cable 100.

[0086] The temperature-sensing optical cable installation assembly 200 provided in this embodiment uses a compression spring 5 to provide clamping force on the laid temperature-sensing optical cable 100 through the first fixing plate 3 and the second fixing plate 4, thereby clamping and fixing the temperature-sensing optical cable 100 and achieving stable installation. The installation and fixing operation using the temperature-sensing optical cable installation assembly 200, as well as its clamping and fixing operation on the temperature-sensing optical cable 100, is relatively easy, simple, and low-cost. The clamping force on the temperature-sensing optical cable can be adjusted by changing the position of the first fixing plate 3, maintaining a firm fixation on the temperature-sensing optical cable with sufficient tension, keeping the temperature-sensing optical cable taut, and improving the accuracy of the correspondence between temperature and position. The temperature-sensing optical cable is installed independently using the temperature-sensing optical cable installation assembly 200, avoiding damage caused by installation within a cable tray, thus solving the problems of easy damage, lack of tension, complex procedures, and high costs associated with current temperature-sensing optical cable installation methods.

[0087] In some embodiments, as shown in Figures 1-6, a fine-tuning bolt 9 is threaded onto the support plate 2. The fine-tuning bolt 9 is parallel to the axis of the compression spring 5, and its inner end extends into the adjustment hole 7.

[0088] A scale line is provided on one side of the adjustment hole 7. When the temperature-sensing optical cable mounting assembly 200 is in its initial state, one end of the scale line is aligned with the fixing bolt 6 furthest from the second fixing plate 4 in the adjustment hole 7. This fixing bolt 6 serves as the reference bolt. When the position of the first fixing plate 3 needs to be precisely adjusted, the fixing bolt 6 is loosened, and the fine-tuning bolt 9 is rotated simultaneously, keeping the fine-tuning bolt 9 against the reference bolt until the reference bolt moves to the required scale line. By precisely adjusting the position of the reference bolt, the movement stroke of the first fixing plate 3 is precisely controlled, ensuring accurate deformation of the compression spring 5 and providing sufficient pressure to maintain the stable clamping and fixing of the temperature-sensing optical cable 100.

[0089] In some embodiments, as shown in Figures 1-6, a fine-tuning bolt 9 is inserted at the end of the support plate 2 away from the base 1. The axial direction of the fine-tuning bolt 9 is parallel to the axial direction of the compression spring 5, and one end of the fine-tuning bolt 9 extends into the adjustment hole 7 and abuts against the fixing bolt 6. By rotating the fine-tuning bolt 9, the position of the fixing bolt 6 in the adjustment hole 7 can be adjusted to achieve precise adjustment.

[0090] In some embodiments, a scale line is provided on the support plate 2 near the adjustment hole 7, and the scale line is arranged along the length direction of the adjustment hole 7. The fixing bolt 6 furthest from the second fixing plate 4 (i.e., the fixing bolt 6 closest to the fine-tuning bolt 9) is used as the reference bolt. By rotating the fine-tuning bolt 9, it is pressed against the reference bolt and pushed to move along the scale line. This achieves precise adjustment of the position of the first fixing plate 3, thereby precisely controlling the deformation of the compression spring 5, and further achieving precise control of the clamping force of the temperature-sensing optical cable 100.

[0091] In some embodiments, as shown in FIG1, a handle 10 is mounted on the second fixing plate 4, and the handle 10 is located on the surface of the second fixing plate 4 away from the first fixing plate 3. The handle 10 facilitates the application of an external force away from the first fixing plate 3 to the second fixing plate 4, compressing the compression spring 5 and pulling the rubber pad 8 on the second fixing plate 4 away from the rubber pad 8 on the first fixing plate 3, so that the temperature-sensing optical cable can easily enter the gap between the two rubber pads 8, and clamp and fix the temperature-sensing optical cable 100 after the handle 10 is released.

[0092] In some embodiments, as shown in FIG1, a guide post 11 is mounted on the base 1, and a compression spring 5 is sleeved on the guide post 11. The compression spring 5 slides in contact with the outer wall of the guide post 11, and the guide post 11 keeps the compression spring 5 axially deformed, which can provide pressure more accurately and sufficiently to maintain the stability of the temperature-sensing optical cable clamp.

[0093] Based on the aforementioned temperature-sensing optical cable installation assembly 200, this application also provides a temperature-sensing optical cable installation process. This process uses the aforementioned temperature-sensing optical cable installation assembly 200 to install the temperature-sensing optical cable 100, as shown in Figure 7, and includes the following steps:

[0094] In step S10, multiple temperature-sensing optical cable installation assemblies 200 are used. The first fixing plate 3 of each temperature-sensing optical cable installation assembly 200 is moved to the second fixing plate 4 for the first time. The first fixing plate 3 is fixed when the moving distance of each first fixing plate 3 reaches the first set distance L1.

[0095] In step S10, before the first fixing plate 3 moves for the first time, the position of the first fixing plate 3 causes the temperature-sensing optical cable mounting assembly 200 to be in its initial state, that is, the first fixing plate 3 is located in the aforementioned first position; when the first fixing plate 3 is fixed in the first position, and the temperature-sensing optical cable 100 is clamped between the first fixing plate 3 and the second fixing plate 4, the compression spring 5 is in a non-elastic deformation state. Through the first movement, the first fixing plate 3 moves a first predetermined distance L1 relative to its initial position towards the base 1.

[0096] The first movement distance is the first set distance L1. After the first movement of each temperature-sensing optical cable installation component 200 is completed, the corresponding first fixing plate 3 is fixed by tightening the fixing bolt 6, thereby adjusting each temperature-sensing optical cable installation component 200 from the initial state to the working state.

[0097] Step S20, as shown in Figure 8a, install the first temperature-sensing optical cable installation assembly 200-1 on the top plate at the front end of the tunnel, lift the winch 300 with the temperature-sensing optical cable 100 wound around it to the rear side of the first temperature-sensing optical cable installation assembly 200-1, pull one end of the temperature-sensing optical cable 100 out of the winch 300, and clamp and fix it between the first fixing plate 3 and the second fixing plate 4 of the first temperature-sensing optical cable installation assembly 200-1.

[0098] In some embodiments of step S20 above, when the temperature-sensing optical cable 100 is clamped between the first fixing plate 3 and the second fixing plate 4, the second fixing plate 4 is moved away from the first fixing plate 3 (for example, an external force can be applied by means of the handle 10 installed on the second fixing plate 4), so that a gap is formed between the rubber pad 8 on the second fixing plate 4 and the rubber pad 8 on the first fixing plate 3, allowing the temperature-sensing optical cable 100 to enter; after the temperature-sensing optical cable 100 is placed in the gap, the external force acting on the second fixing plate 4 is removed, and under the action of the compression spring 5, the second fixing plate 4 is pushed towards the first fixing plate 3, so that the temperature-sensing optical cable 100 is clamped between the first fixing plate 3 and the second fixing plate 4.

[0099] Step S30, as shown in Figure 8b, the winch 300 is moved backward. The second temperature-sensitive optical cable installation assembly 200-2 is installed on the tunnel roof adjacent to the front side of the winch 300. The temperature-sensitive optical cable 100 pulled out as the winch 300 moves is clamped and fixed between the first fixing plate 3 and the second fixing plate 4 of the second temperature-sensitive optical cable installation assembly 200-2, as shown in Figure 8c. The temperature-sensitive optical cable on the rear side of the second temperature-sensitive optical cable installation assembly 200-2 (i.e., the temperature-sensitive optical cable 100 between the current winch 300 and the second temperature-sensitive optical cable installation assembly 200-2) is connected to the tension gauge 400. The tension gauge 400 is pulled horizontally backward so that its tension value reading reaches the set tension F. Thus, the temperature-sensitive optical cable is pulled by the tension gauge 400, straightening and tightening the temperature-sensitive optical cable between the second temperature-sensitive optical cable installation assembly 200-2 and the first temperature-sensitive optical cable installation assembly 200-1. Then the tension gauge 400 is removed.

[0100] As shown in Figure 8d, the winch 300 is moved backward once more. After the winch 300 has moved, the third temperature-sensitive optical cable installation assembly 200-3 is installed on the adjacent tunnel roof in front of it. The newly pulled-out temperature-sensitive optical cable is clamped and fixed on the third temperature-sensitive optical cable installation assembly 200-3, as shown in Figure 8e. The tension gauge 400 is installed on the temperature-sensitive optical cable 100 between the third temperature-sensitive optical cable installation assembly 200-3 and the winch 300. The tension gauge 400 is pulled horizontally backward until its tension value reaches the set tension F. The temperature-sensitive optical cable between the third temperature-sensitive optical cable installation assembly 200-3 and the second temperature-sensitive optical cable installation assembly 200-2 is straightened and tightened. Then the tension gauge 400 is removed.

[0101] Following the aforementioned method, the winch 300 is moved backward multiple times. After each movement of the winch 300, a temperature-sensitive optical cable installation assembly 200 is installed in front of it, thus sequentially installing the fourth, fifth, sixth...Nth temperature-sensitive optical cable installation assembly, where N is a natural number greater than 6. All installed temperature-sensitive optical cable installation assemblies 200 are aligned on the same horizontal line.

[0102] Each time the winch 300 moves, the newly pulled-out temperature-sensitive optical cable 100 is first clamped and fixed to the newly installed temperature-sensitive optical cable mounting assembly 200. Then, a tension gauge 400 is connected to the rear end of the temperature-sensitive optical cable 100 and pulled horizontally backward. Each time the temperature-sensitive optical cable is pulled by the tension gauge 400, the tension value reading of the tension gauge 400 is the set tension F, thereby straightening and tightening the temperature-sensitive optical cable between the newly installed temperature-sensitive optical cable mounting assembly 200 and the adjacent temperature-sensitive optical cable mounting assembly 200 on the front side.

[0103] Finally, when the temperature-sensing installation components were installed on the roof slab at the rear of the tunnel, the winch had moved horizontally out of the tunnel from the rear. At this point, the installation of all temperature-sensing installation components was completed from front to back on the tunnel roof slab, and each temperature-sensing installation component effectively clamped and fixed the temperature-sensing optical cable at the corresponding position.

[0104] In step S40, the first fixing plate 3 of the temperature-sensing optical cable installation assembly 200 is moved to the second fixing plate 4 one by one from front to back. The first fixing plate is fixed when the moving distance reaches the second set distance L2.

[0105] After the second movement of each temperature-sensing optical cable installation assembly 200 is completed, the corresponding first fixing plate 3 will be fixed by tightening the fixing bolt 6, thereby further increasing the elastic deformation of the compression spring 5 in the working state of the temperature-sensing optical cable installation assembly 200 and improving its clamping force on the temperature-sensing optical cable.

[0106] In step S40 above, "the moving distance reaches the second set distance L2" means that the first fixing plate 3 moves a second set distance L2 relative to the position where the temperature-sensing optical cable mounting assembly 200 is in its initial state (i.e., the aforementioned first position) towards the base 1. In other words, during the second movement, the actual distance moved by the first fixing plate 3 is L2-L1.

[0107] The first fixing plate 3 of the temperature-sensing optical cable installation assembly 200 is moved a second time from front to back, as shown in Figures 8f and 9. When the number of temperature-sensing optical cable installation assemblies 200 that have completed the second movement of the first fixing plate 3 reaches 40% of the total number of temperature-sensing optical cable installation assemblies 200, installation limiting clamps 500 are fitted onto the temperature-sensing optical cables on the rear side of the temperature-sensing optical cables of the temperature-sensing optical cable installation assemblies 200 that have not undergone the second movement. The limiting clamps 500 are all attached to the adjacent temperature-sensing optical cable installation assemblies 200 on the front side. As shown in Figure 9, the limiting clamps 500 are detachable clamps that hold the temperature-sensing optical cable tightly. They protrude relative to the outer wall of the temperature-sensing optical cable and are attached to the temperature-sensing optical cable installation assembly 200 to prevent the temperature-sensing optical cable from moving forward.

[0108] The aforementioned limiting clamp 500 can be achieved using existing clamp structures. For example, the clamp consists of two semi-circular clamp plates connected by a hinge, with the distance between the two clamp plates adjusted by a nut, and rubber anti-slip strips provided on the inner sides of the two clamp plates.

[0109] Step S50: For the temperature-sensing optical cable installation assembly 200 that has not been moved a second time, that is, the temperature-sensing optical cable installation assembly 200 with the limit clamp 500 installed on the rear side, the first fixing plate 3 is moved to the second fixing plate 4 one by one from front to back. The first fixing plate is fixed when the moving distance reaches the second set distance L2.

[0110] This completes the second movement of the first fixing plate 3 in the subsequent temperature-sensing optical cable installation assembly 200. After the second movement of each temperature-sensing optical cable installation assembly 200 is completed, the corresponding first fixing plate 3 is fixed by tightening the fixing bolts 6.

[0111] In the temperature-sensing optical cable installation process provided in the above embodiments of this application, by controlling the moving distance of the first fixing plate 3, the deformation of the compression spring 5 when the temperature-sensing optical cable is clamped and fixed by the temperature-sensing optical cable installation assembly 200 is controlled, thereby controlling the clamping force.

[0112] In some embodiments, in step S10, before each temperature-sensing optical cable installation assembly 200 is installed and fixed to the tunnel roof, all temperature-sensing optical cable installation assemblies 200 can be adjusted from their initial state to their working state on the ground, so that after the temperature-sensing optical cable installation assemblies 200 are installed on the tunnel roof, they can be immediately used for clamping and fixing the temperature-sensing optical cable 100.

[0113] In step S20, the first temperature-sensing optical cable mounting assembly 200 is installed starting from the front end, and is used to clamp and fix the end of the temperature-sensing optical cable, providing a fixed foundation for the subsequent extraction of the temperature-sensing optical cable from the winch 300.

[0114] In some embodiments, in order to ensure that the winch 300 and the installed first temperature-sensing optical cable installation assembly 200 are adjacent to each other, i.e., the distance between them is short, a mobile lifting platform vehicle 600 is used to perform the installation operation of the temperature-sensing optical cable installation assembly 200.

[0115] Specifically, the winch 300 is fixed to the rear of the mobile lifting platform vehicle 600, and the temperature-sensing optical cable installation component 200 is installed at the front of the mobile lifting platform vehicle 600. The space of the mobile lifting platform vehicle 600 is small, so it is ensured that the winch 300 and the installed temperature-sensing optical cable installation component 200 are adjacent to each other.

[0116] In step S30, by moving the mobile lifting platform vehicle 600 backwards one after another, the winch 300 can be moved backwards and the new temperature-sensing optical cable can be pulled out. At the same time, a new temperature-sensing optical cable installation component 200 is installed on the mobile lifting platform vehicle 600 nearby, so that it is set up adjacent to the winch 300 one after the other with a close distance.

[0117] In some embodiments, the first predetermined distance Second set distance Set tension F = c × F max a is 80%, b is 90%, c is 85%, F max denoted as , where is the tensile strength of the temperature-sensing optical cable, D is the mean diameter of the compression spring 5, n is the effective number of turns of the compression spring 5, G is the shear modulus of the material used in the compression spring 5, d is the diameter of the steel wire of the compression spring 5, and μ is the coefficient of friction between the outer sheath of the temperature-sensing optical cable and the rubber pad 8.

[0118] Tensile strength value F max The coefficient of friction μ was obtained through performance testing in the laboratory. Since both sides of the temperature-sensing optical cable are clamped by rubber pads 8 made of the same material, the measurement of the coefficient of friction μ is ensured to be accurate. The mean diameter D, the effective number of coils n, and the wire diameter d of the compression spring 5 are all dimensional parameters of the compression spring 5 and can be obtained directly. The shear modulus G is obtained by referring to a table based on the material used in the compression spring 5.

[0119] In the above embodiment, by accurately calculating the first set distance L1, when the elastic force generated by the compression spring 5 acts on the temperature-sensing optical cable 100 through the second fixing plate 4 and the rubber pad 8, the temperature-sensing optical cable 100 can generate a frictional force of about 80% of its tensile strength value.

[0120] Set tension F = c × Fmax The temperature-sensing optical cable 100 is pulled by the tension gauge 400 to tighten it and make the tension on the temperature-sensing optical cable 100 reach 85% of its tensile strength value. After the temperature-sensing optical cable 100 is clamped and fixed on the temperature-sensing optical cable installation assembly 200, it has sufficient tension to maintain its straightness and accurately measure the temperature at various locations along the tunnel.

[0121] When the temperature-sensing optical cable is pulled using the tension gauge 400, after the first movement, the clamping force of the temperature-sensing optical cable mounting assembly 200 generates a frictional force equivalent to 80% of the tensile strength value when applied to the temperature-sensing optical cable. The horizontal tension generated by pulling the temperature-sensing optical cable can overcome the frictional force and the reverse tension generated by the weight of the temperature-sensing optical cables between the temperature-sensing optical cable mounting assemblies 200, allowing the clamped temperature-sensing optical cable to move horizontally, thereby shortening the length of the temperature-sensing optical cable between adjacent temperature-sensing optical cable mounting assemblies 200, straightening this part of the temperature-sensing optical cable, and keeping the straightened temperature-sensing optical cable taut with a tension of 85% of the tensile strength value.

[0122] In addition, when the temperature-sensing optical cable is pulled by the tension gauge 400, the temperature-sensing optical cable between the two temperature-sensing optical cable mounting components 200 on the front side of the tension gauge 400 is not taut. The tension force acting on the temperature-sensing optical cable 100 by the tension gauge 400 first acts on the temperature-sensing optical cable between the first adjacent temperature-sensing optical cable mounting component 200 on the front side and the connection point of the tension gauge 400. This section of the temperature-sensing optical cable is only subjected to the friction force generated by the clamping of the first adjacent temperature-sensing optical cable mounting component 200 on the front side. The tension force can overcome the sum of the friction force and the reverse tension force generated by the weight of the temperature-sensing optical cable on the front side, causing this section of the temperature-sensing optical cable to move backward under the action of the tension force, thereby taut and straightening the temperature-sensing optical cable between the first and second adjacent temperature-sensing optical cable mounting components 200 on the front side. When the temperature-sensing optical cable is taut and straightened, it will exert a horizontal pull on the second adjacent temperature-sensing optical cable mounting component 200. At this time, due to the friction generated by the two temperature-sensing optical cable mounting components 200 as resistance, and by using a tensile force of 85% of the tensile strength to pull the temperature-sensing optical cable, it will be unable to overcome the double friction force, thus maintaining fixation and tautness.

[0123] In step S40, the first fixing plate 3 in the temperature-sensing optical cable installation assembly 200 is moved and adjusted for the second time from front to back. Through the precise calculation of the second set distance 200, when the elastic force generated by the compression spring 5 acts on the temperature-sensing optical cable through the second fixing plate 4 and the rubber pad 8, the friction force generated on the temperature-sensing optical cable is increased to about 90% of the tensile strength value, which enhances the clamping and fixing effect of the temperature-sensing optical cable and keeps the temperature-sensing optical cable stable under the tension of 85% of the tensile strength value.

[0124] Furthermore, each time a temperature-sensing optical cable installation assembly 200 undergoes a second movement adjustment, a certain height difference is created between it and the adjacent temperature-sensing optical cable installation assembly 200, resulting in a pull on the temperature-sensing optical cables between them. In the initial stage of the second movement adjustment, the number of temperature-sensing optical cable installation assemblies 200 that have completed the second movement adjustment is small. The sum of the frictional forces generated by the pressure acting on the temperature-sensing optical cables is less than the sum of the frictional forces generated by the temperature-sensing optical cable installation assemblies 200 that have not completed the second movement adjustment. Because the second movement adjustment causes a pull on the temperature-sensing optical cables between adjacent temperature-sensing optical cable installation assemblies 200, it will not cause the rear temperature-sensing optical cable to be pulled forward and move, remaining stationary. Moreover, the resulting height difference is on the order of centimeters, and the horizontal spacing is on the order of ten meters; the resulting pull will not break the temperature-sensing optical cable. When 40% of the temperature-sensing optical cable installation assemblies 200 have completed the second movement adjustment, further increasing the number of temperature-sensing optical cable installation assemblies 200 that have completed the second movement adjustment will cause the front pulling force to be greater than the total frictional force at the rear, resulting in the rear temperature-sensing optical cable being pulled forward.

[0125] To avoid the above situation, in step S40, a limiting clamp 500 is fixedly installed on the temperature-sensing optical cable. The limiting clamp 500 presses against the temperature-sensing optical cable installation assembly 200 to prevent the temperature-sensing optical cable from moving forward under tension. This prevents the temperature-sensing optical cables between adjacent temperature-sensing optical cable installation assemblies 200 from becoming loose due to tension after all temperature-sensing optical cable installation assemblies 200 have completed the second movement adjustment.

[0126] In step S50, the second movement and adjustment of the subsequent temperature-sensing optical cable installation components 200 are carried out, thereby lifting all the temperature-sensing optical cable installation components 200. The friction force generated by each component is greater than the tension force of the temperature-sensing optical cable, thus improving the stability of the temperature-sensing optical cable after installation.

[0127] Finally, the entire temperature-sensing optical cable is clamped and fixed along the tunnel ceiling from front to back by the various temperature-sensing optical cable installation components 200, ensuring stable installation. Sufficient tension on the cable keeps it taut, guaranteeing accurate temperature measurement. The construction process requires only a mobile lifting platform vehicle 600 and the equipment for installing the temperature-sensing optical cable installation components 200, making operation simple and convenient.

[0128] In some embodiments, the spacing between adjacent temperature-sensing optical cable mounting assemblies 200 is less than a predetermined spacing L3. Where q is the weight of one meter of temperature-sensing optical cable.

[0129] Based on the precise setting of the spacing L3, the spacing between the temperature-sensing optical cable installation components 200 is precisely limited, ensuring that the temperature-sensing optical cables between adjacent temperature-sensing optical cable installation components 200 will not bend or deform due to excessive length, thereby preventing the temperature-sensing optical cables from deforming and loosening, and maintaining effective tautness for a long time.

[0130] In some embodiments, due to the poor flatness of the tunnel roof, the temperature-sensing optical cable installation assembly 200 is installed on the leveling pad 700 provided on the tunnel roof. That is, by using the leveling pad 700 of the corresponding thickness, each temperature-sensing optical cable installation assembly 200 is adjusted to the same height and aligned in the front-to-back direction. This ensures that after clamping and fixing, the temperature-sensing optical cable 100 remains horizontal and coaxial, ensuring that the correspondence between the temperature measured by the temperature-sensing optical cable 100 and the position is accurate, so that the fire early warning system can accurately locate the fire source.

[0131] This application does not impose any restrictions on the structure of the leveling pad, as long as it can provide a lower surface located on the same horizontal plane.

[0132] In some embodiments, during step S40, when installing the limiting clamps 500, they are installed one by one from back to front.

[0133] Starting from the middle of the entire temperature-sensing optical cable, the limiting clamp 500 is installed. The increasing weight of the limiting clamp 500 acts on the middle of the temperature-sensing optical cable, causing the temperature-sensing optical cable to be pulled forward under the weight of the limiting clamp 500, resulting in the temperature-sensing optical cable becoming loose.

[0134] When installed from back to front, the weight of the limiting clamp 500 will pull the temperature-sensing optical cable backward, preventing it from becoming loose due to pressure from the clamp and keeping it taut and straight to maintain the accuracy of the temperature measurement position.

[0135] In some embodiments, when the temperature-sensing optical cable mounting assembly 200 is installed on the tunnel roof, the temperature-sensing optical cable mounting assembly 200 is installed upside down, with its second fixing plate 4 placed above the first fixing plate 3, and its base 1 fixedly connected to the tunnel roof.

[0136] When the temperature-sensing optical cable is clamped and fixed on the temperature-sensing optical cable installation assembly 200 by inverting the installation, it is placed on the rubber pad 8 on the first fixing plate 3. This ensures that each clamping and fixing point is aligned on the horizontal line, making it easier to avoid height differences and making it easier to install the entire temperature-sensing optical cable in a horizontal state.

[0137] In addition, the temperature-sensing optical cable installation assembly 200 has a fine-adjustment bolt 9, which is inserted into the adjustment hole 7 from bottom to top. When adjusting, the fixing bolt 6 is pushed upwards and the fixing bolt 6 falls on the fine-adjustment bolt 9. The axial movement stroke of the fine-adjustment bolt 9 can accurately correspond to the movement stroke of the first fixing plate 3, and it is convenient to adjust the clamping force after the temperature-sensing optical cable has been clamped and fixed.

[0138] In some embodiments, each time a second movement of a temperature-sensing optical cable installation assembly 200 is completed, that is, a rear adjacent limiting clamp 500 is removed, thereby quickly reducing the pressure of the limiting clamp 500 installation on the temperature-sensing optical cable and ensuring the stability of the temperature-sensing optical cable during installation.

[0139] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0140] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
