Description
Technical Field
[0001] The utility model relates to the technical field of temperature testing devices, in particular to an instrument suitable for temperature testing of tunnel temperature-sensitive optical fibers. Background Technique
[0002] The device for temperature testing of tunnel temperature-sensitive optical fibers is mainly a tunnel distributed optical fiber temperature measurement device. This device combines optical fiber sensing technology and advanced signal processing technology, and can achieve high-precision, long-distance, and real-time monitoring of the temperature in the tunnel.
[0003] In the prior art, some workers also use a handheld intelligent resistance thermometer to detect the temperature of the optical fiber when monitoring the temperature of the optical fiber in the tunnel. Generally, a metal probe is placed on the optical fiber to detect its external temperature, and then the data is transmitted back to the thermometer by the sensor wire for analysis.
[0004] However, when using the thermometer currently, it is necessary to use a probe to sample and detect the temperature of different areas of the optical fiber. Only through the probe, the temperature of the optical fiber cannot be detected flexibly. When detecting the optical fiber at a high place, it is not convenient enough and cannot cooperate well with the workers to detect the temperature of the optical fiber in the tunnel. Content of the Utility Model
[0005] Based on this, the purpose of the present utility model is to provide an instrument suitable for temperature testing of tunnel temperature-sensitive optical fibers, so as to solve the technical problems that when using a thermometer currently, it is necessary to use a probe to sample and detect the temperature of different areas of the optical fiber, and only through the probe, the temperature of the optical fiber cannot be detected flexibly. When detecting the optical fiber at a high place, it is not convenient enough and cannot cooperate well with the workers to detect the temperature of the optical fiber in the tunnel.
[0006] To achieve the above purpose, the present utility model provides the following technical solution: An instrument suitable for temperature testing of tunnel temperature-sensitive optical fibers, including a temperature measurement device body. A sensor wire is connected to the top of the temperature measurement device body, and the other end of the sensor wire is fixed to a handle. One end of the handle is fixedly connected to a telescopic rod. A second fixing block is fixedly installed at the top of the telescopic rod. Two clamping blocks are rotatably connected to both sides of the top of the second fixing block in a symmetric structure. An induction block for cooperating with the sensor wire is fixedly installed at the top of the clamping block. A first convex block is rotatably connected to the inner side of the clamping block. A connecting rod is rotatably connected to the outer side of the first convex block. A steel column is rotatably connected between the connecting rods. A steel rope is fixedly connected to the bottom of the steel column. A winding structure for cooperating with the steel rope is arranged inside the telescopic rod.
[0007] By adopting the above technical solution, during use, the telescopic rod is expanded, and the length of the telescopic rod can be adjusted according to actual use needs. Then, hold the handle and move the end of the entire telescopic rod to the place to be detected. Then, through the mutual cooperation between the winding structure, the steel rope, the connecting rod, and the first convex block, the steel rope and the steel column move downward simultaneously. When the steel column moves downward, it has a pulling effect on the connecting rod and the first convex block. The first convex block is rotatably connected to the clamping block, and the clamping block is rotatably connected to the second convex block. Therefore, when the steel column moves downward, it will drive the clamping blocks to approach each other, so that the sensing block clamps the optical fiber. The temperature of the optical fiber is clamped and monitored by the sensing block, and the data is transmitted back to the temperature measuring device body through the sensor wire. Then, the temperature measuring device body collects, processes, and analyzes the data. With this structure, it is beneficial to cooperate with the staff to collect the temperature of the optical fiber at high places point by point, can better monitor the temperature of the optical fiber, and is beneficial to improving the practicability and flexibility of the entire instrument applicable to the temperature sensing of optical fibers in tunnels.
[0008] The present utility model is further configured such that the telescopic rod includes a first connecting rod, a second connecting rod, and a third connecting rod. The third connecting rod is fixedly connected to the handle. The second connecting rod is movably connected to the third connecting rod. The first connecting rod is movably connected to the second connecting rod. The diameter of the first connecting rod is smaller than that of the second connecting rod. The diameter of the second connecting rod is smaller than that of the third connecting rod. A damping structure is provided between the first connecting rod, the second connecting rod, and the third connecting rod.
[0009] By adopting the above technical solution, the mutual cooperation between the first connecting rod, the second connecting rod, and the third connecting rod can adjust the length of the telescopic rod according to actual use conditions. Moreover, due to the telescopic effect of the telescopic rod itself, the telescopic rod can be flexibly stored, and it is more convenient for carrying and transportation. At the same time, through the damping structure between the first connecting rod, the second connecting rod, and the third connecting rod, the telescopic rod can maintain a certain stable effect even after being fully expanded.
[0010] The present utility model is further configured such that the winding structure is located inside the third connecting rod. The winding structure includes a rotating shaft, a first coil spring, and a gear. A winding shaft is provided between the rotating shafts. The gears are fixed to both ends of the rotating shaft. The rotating shaft is rotatably connected to the third connecting rod. The first coil spring is located on both sides of the gear. The steel rope is wound around the winding shaft. A driving structure for cooperating with the winding structure is fixedly installed on the outer side of the third connecting rod.
[0011] By adopting the above technical solution, when the winding structure is located inside the third connecting rod, it can cooperate better with the handle and the driving structure. The driving structure enables the gear and the rotating shaft to rotate inside the third connecting rod, so as to achieve the effect of releasing and winding the steel rope. Moreover, through the first coil spring, when the first connecting rod and the second connecting rod are retracted into the third connecting rod, due to the characteristics of the first coil spring itself, the winding shaft can rotate in one direction, which is beneficial to winding the steel rope back into the winding shaft again.
[0012] The utility model is further configured that the driving structure includes a first fixing block, a button, a pressing column, and a rack. The first fixing block is fixed on the outer side of the third connecting rod, the button is fixed on the outer side of the first fixing block, the pressing column is fixed on the inner side of the button, the pressing column is fixedly connected with the rack, and the rack is meshed with the gear.
[0013] By adopting the above technical solution, during use, the button is squeezed, so that the pressing column drives the rack to move downward synchronously. Through the meshing relationship between the rack and the gear, the gear can rotate inside the third connecting rod, so as to achieve the effect of winding the steel rope. When the steel rope is wound, the steel column can be driven to move downward.
[0014] The utility model is further configured that the button is made of rubber material, and a first movable groove for cooperating with the pressing column and the rack is formed inside the first fixing block.
[0015] By adopting the above technical solution, when the button is made of rubber material, the button can have better deformation ability, which is beneficial to squeezing the button well. Through the first movable groove, it is beneficial for the pressing column and the rack to move up and down flexibly inside the first fixing block.
[0016] The utility model is further configured that a second convex block is fixedly connected to the bottom of the clamping block, second movable grooves for cooperating with the second convex block are formed on both sides of the second fixing block, the second convex block is rotationally connected with the second movable grooves, and a second coil spring is arranged at the connection between the second convex block and the second movable grooves.
[0017] By adopting the above technical solution, when the second convex block is rotationally connected with the second movable groove, the clamping block can move better inside the second fixing block to cooperate with the sensing block to clamp the optical fiber. Moreover, through the second coil spring between the second convex block and the second movable groove, it is beneficial for the clamping block to stably clamp the optical fiber. When the steel rope and the steel column are retracted, due to the performance of the coil spring itself, the clamping block and the sensing block can quickly reset to the initial state.
[0018] The utility model is further configured that a plurality of arc-shaped grooves are arranged on the outer side of the handle.
[0019] By adopting the above technical solution, the provided arc-shaped groove is beneficial for better fitting the palm and fingers, enabling the staff to better hold the handle for use.

When the steel column moves downward, it has a pulling effect on the connecting rod and the first convex block. The first convex block is rotatably connected to the clamping block, and the clamping block is rotatably connected to the second convex block. Therefore, when the steel column moves downward, it will drive the clamping blocks to approach each other, thereby enabling the sensing block to clamp the optical fiber. The temperature of the optical fiber is clamped and monitored by the sensing block, and the data is transmitted back to the temperature measuring device body through the sensor wire. Then, the temperature measuring device body collects, processes, and analyzes the data.

Specific embodiments
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0032] Next, the embodiments of the present utility model will be described according to its overall structure.
[0033] An instrument applicable to tunnel temperature-sensing optical fiber temperature measurement, as Figures 1-7 shown, includes a body 1 of the temperature measuring device. A sensor wire 3 is connected to the top of the body 1 of the temperature measuring device. The other end of the sensor wire 3 is fixed to a handle 4. One end of the handle 4 is fixedly connected to a telescopic rod 2. A second fixing block 7 is fixedly installed at the top of the telescopic rod 2. Clamping blocks 8 are rotatably connected to both sides of the top of the second fixing block 7 in a symmetric structure. An induction block 9 for cooperating with the sensor wire 3 is fixedly installed at the top of the clamping block 8. A first convex block 16 is rotatably connected to the inner side of the clamping block 8. A connecting rod 17 is rotatably connected to the outside of the first convex block 16. A steel column 10 is rotatably connected between the connecting rods 17. A steel wire rope 11 is fixedly connected to the bottom of the steel column 10. A winding structure for cooperating with the steel wire rope 11 is arranged inside the telescopic rod 2.
[0034] During use, expand the telescopic rod 2. The length of the telescopic rod 2 can be adjusted according to actual usage needs. Then, hold the handle 4 and move the end of the entire telescopic rod 2 to the place where detection is required. Then, through the mutual cooperation of the winding structure, the steel rope 11, and the connecting rod 17 and the first convex block 16, the steel rope 11 and the steel column 10 move downward simultaneously. When the steel column 10 moves downward, it has a pulling effect on the connecting rod 17 and the first convex block 16. The first convex block 16 is rotatably connected to the clamping block 8, and the clamping block 8 is rotatably connected to the second convex block 21. Therefore, when the steel column 10 moves downward, it will drive the clamping blocks 8 to approach each other, so that the sensing block 9 clamps the optical fiber. The temperature of the optical fiber is clamped and monitored by the sensing block 9, and the data is transmitted back to the temperature measuring device body 1 through the sensor wire 3. Then, the temperature measuring device body 1 collects, processes, and analyzes the data. With this structure, it is beneficial to cooperate with the staff to collect the temperature of the optical fiber at high places point by point, and can better monitor the temperature of the optical fiber, thereby improving the practicability and flexibility of the entire instrument applicable to the temperature sensing of optical fibers in tunnels.
[0035] Furthermore, through the mutual cooperation of the first connecting rod 201, the second connecting rod 202, and the third connecting rod 203, the length of the telescopic rod 2 can be adjusted according to actual usage conditions. Moreover, due to the telescopic effect of the telescopic rod 2 itself, the telescopic rod 2 can be flexibly stored, and it is more convenient for carrying and transportation. At the same time, through the damping structure between the first connecting rod 201, the second connecting rod 202, and the third connecting rod 203, a certain stable effect can be maintained after the telescopic rod 2 is fully expanded. And when the winding structure is located inside the third connecting rod 203, it can better cooperate with the handle 4 and the driving structure. The driving structure rotates the gear 19 and the rotating shaft 12 inside the third connecting rod 203, so as to achieve the effect of releasing and winding the steel rope 11. And through the first coil spring 18, when the first connecting rod 201 and the second connecting rod 202 are retracted into the third connecting rod 203, due to the characteristics of the first coil spring 18 itself, the winding shaft can rotate in one direction, which is beneficial to rewinding the steel rope 11 back into the winding shaft.
[0036] In this embodiment, by pressing the button 6, the pressing column 13 drives the rack 14 to move downward synchronously. Due to the meshing relationship between the rack 14 and the gear 19, the gear 19 can rotate within the third connecting rod 203, thereby achieving the effect of winding the steel rope 11. After the steel rope 11 is wound, it can drive the steel column 10 to move downward. When the button 6 is made of rubber material, the button 6 has good deformation ability, which is conducive to squeezing the button 6 well. Through the first movable groove 15, it is beneficial for the pressing column 13 and the rack 14 to move up and down flexibly within the first fixing block 5. When the second convex block 21 is rotatably connected to the second movable groove 22, the clamping block 8 can move better within the second fixing block 7, cooperating with the sensing block 9 to clamp the optical fiber. And due to the second coil spring 20 between the second convex block 21 and the second movable groove 22, it is beneficial for the clamping block 8 to stably clamp the optical fiber. When the steel rope 11 and the steel column 10 are retracted, the performance of the second coil spring 20 itself can enable the clamping block 8 and the sensing block 9 to quickly reset to the initial state. Finally, the arranged arc-shaped groove is beneficial for better fitting the palm and fingers, enabling the staff to hold the handle 4 better for use.
