[0002] With the rapid development of rail transit, it not only facilitates public travel and alleviates traffic congestion, but also reduces environmental pollution caused by vehicle exhaust. It has now become the most common mode of transportation for citizens. Tunnels are generally equipped with multiple temperature-sensing optical fibers to detect fires within stations.

[0003] In traditional tunnels, temperature-sensing optical fibers are typically laid parallel to steel wires, with a stainless steel wire tie used every meter to secure the fiber and wire.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0023] The present invention provides a temperature-sensitive optical fiber fixing bracket. Figure 1-4 As shown, it includes a bracket body 1, a pressing piece 2 and a fixing piece 3; the bracket body 1 includes a mounting plate 11, a fixing plate 12 and a support plate 13; the two ends of the support plate 13 are respectively connected to the mounting plate 11 and the fixing plate 12; the mounting plate 11 is connected to the tunnel; the temperature-sensitive optical fiber is arranged between the fixing plate 12 and the pressing piece 2, and the outer sides of the temperature-sensitive optical fiber are in contact with the fixing plate 12 and the pressing piece 2; the fixing piece 3 is connected to the side of the fixing plate 12 close to the pressing piece 2; the fixing plate 12 is connected to one end of the pressing piece 2, and the other end of the pressing piece 2 is clamped with the fixing piece 3, and the other end of the pressing piece 2 is configured to move towards or away from the fixing plate 12.

[0024] For example, when installing the temperature-sensitive optical fiber on the fixed bracket, since the material used for the pressing plate 2 has a certain elasticity, the free end of the pressing plate 2 can be lifted, and then the temperature-sensitive optical fiber can be installed between the pressing plate 2 and the fixed plate 12. Due to the squeezing force of the pressing plate 2 and the fixed plate 12, the temperature-sensitive optical fiber can be firmly installed on the fixed bracket.

[0025] For example, when installing the temperature-sensitive optical fiber on a fixed bracket, after the temperature-sensitive optical fiber has been squeezed and fixed, a fixing part 3 is used at the free end of the pressing plate 2 to further fix the pressing plate 2, thereby improving the reliability of the temperature-sensitive optical fiber installation and reducing the risk of traffic accidents caused by the temperature-sensitive optical fiber falling off. In addition, the pressing and fixing method can greatly improve the construction efficiency of manual installation of the temperature-sensitive optical fiber.

[0026] For example, when removing the temperature-sensitive optical fiber from the fixed bracket, the temperature-sensitive optical fiber can be removed and replaced from the fixed bracket by pulling the free end of the pressing plate 2 out of the fixing member 3 and then taking the temperature-sensitive optical fiber out from between the pressing plate 2 and the fixing plate 12.

[0027] Exemplarily, the pressing piece 2 includes a fixed section, a clamping section and an operating section; the fixing section and the operating section are respectively connected on both sides of the clamping section, the fixed section is connected to the fixing plate 12, the clamping section can be clamped with the fixing member 3, and the angle between the operating section and the clamping section is between 90° and 150°. The operating section can facilitate manual operation of the pressing piece 2, thereby improving the efficiency of installing or disassembling the temperature-sensitive optical fiber.

[0028] For example, there is a certain angle between the mounting plate 11 and the support plate 13, and this angle can be adjusted according to the on-site installation environment; there is a certain angle between the support plate 13 and the fixing plate 12, and this angle can be adjusted according to the actual working position of the on-site temperature-sensing optical fiber.

[0029] Exemplarily, the length of the support plate 13 can be adjusted to meet the actual application of the field temperature sensing optical fiber.

[0030] In the embodiment of this application, Figure 3 As shown, the pressing plate 2 is provided with a mounting groove 21 ; the temperature-sensing optical fiber is arranged in the mounting groove 21 .

[0031] Exemplarily, a groove is opened on one side of the fixing plate 12 close to the pressing plate 2, and the temperature-sensitive optical fiber is arranged in the groove. The positions of the installation groove 21 of the pressing plate 2 and the groove of the fixing plate 12 correspond to each other, which can meet the installation requirements of the temperature-sensitive optical fiber.

[0032] In the embodiment of this application, Figure 4 As shown, the fixing member 3 includes two elastic clips 31 and a mounting seat 32; the two elastic clips 31 are symmetrically arranged, and the two elastic clips 31 are both connected to the mounting seat 32; the introduction port 4 and the clamping opening 5 are sequentially arranged in the middle of the two elastic clips 31 toward the fixing plate 12; the mounting seat 32 is connected to the side of the fixing plate 12 close to the pressing plate 2; the pressing plate 2 is configured to enter the introduction port 4 and the clamping opening 5, and abut against the two elastic clips 31.

[0033] In the embodiment of this application, Figure 4As shown, the two elastic clips 31 each include a clamping section 311, an abutting section 312, an introduction section 313, a first connecting section 314, and a second connecting section 315, which are arranged in sequence from the free end; the two second connecting sections 315 are connected to the mounting seat 32; the two second connecting sections 315 are arranged along the thickness direction of the mounting seat 32; the two first connecting sections 314 are arranged along the thickness direction of the second connecting sections 315 and are located between the two second connecting sections 315; the two introduction sections 313 are respectively connected to the side of the two first connecting sections 314 close to the mounting seat 32, and the two introduction sections 313 are respectively connected to the side of the two first connecting sections 314 close to the mounting seat 32, and the two introduction sections 313 are respectively connected to the side of the two first connecting sections 314 close to the mounting seat 32. The angles between the sections 313 and the two first connecting sections 314 are greater than 90°; the two abutting sections 312 are respectively connected to the side of the two introduction sections 313 close to the mounting seat 32, and the angles between the two abutting sections 312 and the two introduction sections 313 are greater than 90°; the two clamping sections 311 are respectively connected to the side of the two abutting sections 312 close to the mounting seat 32, and the angles between the two clamping sections 311 and the two abutting sections 312 are greater than 90°; the pressing sheet 2 is configured to be slidably connected to the introduction section 313 and the abutting section 312, and to abut against the clamping section 311.

[0034] Exemplarily, the free end of the elastic clip 31 is an end close to the mounting seat 32 and not connected to the mounting seat 32. Since the elastic clip 31 is made of elastic material, when the elastic clip 31 is clamped with the pressing plate 2, the clamping section 311, the abutting section 312 and the introduction section 313 can all move and deform in the direction close to the second connecting section 315.

[0035] In the embodiment of this application, Figure 2 and Figure 4 As shown, the fixing member 3 also includes a mounting piece 33; the mounting piece 33 is connected to the side of the mounting seat 32 away from the elastic clip 31; a sliding groove 121 is opened on the fixing plate 12; the mounting piece 33 passes through the sliding groove 121 and abuts against the side of the fixing plate 12 away from the pressing piece 2, and the mounting seat 32 abuts against the side of the fixing plate 12 close to the pressing piece 2; the fixing member 3 is configured to slide in the sliding groove 121.

[0036] For example, when installing the temperature-sensitive optical fiber on the fixed bracket, it is necessary to lift the free end of the pressing plate 2 so that the temperature-sensitive optical fiber can be installed from the free end of the pressing plate 2. At this time, the fixing member 3 is likely to interfere with the temperature-sensitive optical fiber, which is not conducive to manual installation. Therefore, when installing the temperature-sensitive optical fiber, the fixing member 3 needs to be moved to a suitable position. The mounting piece 33 of the present application can slide in the slide groove 121, thereby realizing the movement of the position of the fixing member 3. It should be noted that the material of the mounting piece 33 is an elastic material. When installing the fixing member 3 on the fixed bracket, by pressing the two mounting pieces 33, the mounting piece 33 can be inserted from the slide groove 121 and can be engaged with the fixing plate 12, thereby realizing the installation and sliding of the fixing member 3 on the fixing plate 12.

[0037] In the embodiment of this application, Figure 2 As shown, a first mounting hole 111 is opened on the mounting plate 11; a second mounting hole 122 is opened on the fixing plate 12; the mounting plate 11 is connected to the tunnel through the first mounting hole 111; the pressing sheet 2 is connected to the fixing plate 12 through the second mounting hole 122.

[0038] In the embodiment of this application, Figure 1-4 As shown, the material of the pressing sheet 2 is 65Mn spring steel.

[0039] In the embodiment of the present application, the material of the fixing member 3 is 65Mn spring steel.

[0040] Exemplarily, the pressing piece 2 and the fixing member 3 may also be made of other elastic materials.

[0041] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
