[0002] The pipeline inner wall melt infiltration online temperature measuring device is used to monitor the melt infiltration temperature of the pipeline inner wall in real time to ensure the safe operation and effective maintenance of the pipeline system.

[0003] In the prior art, when measuring the temperature of the inner wall of a pipe during infiltration online, a temperature sensor is placed inside the pipe to monitor the temperature of the inner wall of the pipe. However, when performing infiltration on the inner wall of the pipe, pipes of different sizes are processed. When the temperature sensor is placed in temperature sensors of different sizes, it cannot be guaranteed that it is in the center of the pipe. The temperature result monitored by the temperature sensor will fluctuate due to the distance between the temperature sensor and the inner wall of the pipe, thereby affecting the effective and accurate monitoring of the inner wall temperature of the pipe, which is not conducive to the monitoring of the pipeline system. Therefore, we propose an online temperature measuring device for infiltration of the inner wall of the pipe. Utility Model Content

[0024] The embodiment of the present application provides an online temperature measurement device for infiltration of the inner wall of a pipeline, which solves the problem that the temperature sensor 1 cannot be ensured to be in the center of the pipeline, and the temperature result monitored by the temperature sensor 1 fluctuates due to the distance between the temperature sensor 1 and the inner wall of the pipeline, thereby affecting the effective and accurate monitoring of the temperature of the inner wall of the pipeline and being detrimental to the monitoring of the pipeline system. The embodiment of the present application provides an online temperature measurement device for infiltration of the inner wall of the pipeline, which solves the problem that the temperature sensor 1 cannot be ensured to be in the center of the pipeline, and the temperature result monitored by the temperature sensor 1 fluctuates due to the distance between the temperature sensor 1 and the inner wall of the pipeline, thereby affecting the effective and accurate monitoring of the temperature of the inner wall of the pipeline and being detrimental to the monitoring of the pipeline system. The spacing between the adjustment seat 301 and the mounting seat 2 is changed, so that the two connecting seats 408 move toward each other and drive the rotating rod 407 to rotate. At this time, the rotating rod 407 pushes the rotating seat 404 to move, so that the contact wheel 401 contacts and squeezes the pipeline. At this time, the contact wheel 401 pushes the movable seat 402 and the sliding rod 403 to move, so that the sliding rod 403 slides along the inner wall of the rotating seat 404. At the same time, the spring 405 is compressed. Under the rebound of the spring 405, the contact wheel 401 contacts the pipeline. Under the squeezing of multiple contact wheels 401, the temperature sensor 1 is confined to the center position inside the pipeline, which facilitates the temperature sensor 1 to perform online temperature measurement of the inner wall of the pipeline, and the temperature measurement is accurate.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The embodiment of the utility model discloses an online temperature measuring device for pipeline inner wall infiltration.

[0027] According to the attached Figure 1-4 As shown, it includes a temperature sensor 1, a mounting base 2, an adjustment unit 3 and multiple limit units 4. The temperature sensor 1 is inserted into the mounting base 2. The temperature sensor 1 and the mounting base 2 are connected and fixed by bolts. The adjustment unit 3 is connected below the mounting base 2.

[0028] The adjustment unit 3 includes a plurality of threaded rods 302 fixedly connected to the mounting base 2. An adjustment base 301 is slidably connected to the outer peripheral wall of the threaded rod 302. By changing the distance between the adjustment base 301 and the mounting base 2, the two connecting bases 408 move toward each other. At this time, the connecting base 408 drives the rotating rod 407 to rotate. At this time, the rotating rod 407 pushes the rotating base 404 to move, adjusting the contact wheel 401 on the rotating base 404 to move, so that the contact wheel 401 contacts and squeezes the pipe;

[0029] The limiting unit 4 is located between the mounting seat 2 and the adjusting unit 3. The limiting unit 4 includes a rotating seat 404 located between the mounting seat 2 and the adjusting unit 3. A sliding rod 403 is slidably connected to the inner wall of the rotating seat 404. A contact wheel 401 is provided at one end of the sliding rod 403. When the contact wheel 401 contacts the inner wall of the pipe, the contact wheel 401 pushes the movable seat 402 and the sliding rod 403 to move, so that the sliding rod 403 slides along the inner wall of the rotating seat 404. At the same time, the spring 405 is compressed. Under the rebound of the spring 405, the contact wheel 401 contacts the pipe. Under the squeezing of multiple contact wheels 401, the temperature sensor 1 is limited to the center position inside the pipe, which facilitates the temperature sensor 1 to perform online temperature measurement of the inner wall of the pipe, and the temperature measurement is accurate.

[0030] The outer wall of the threaded rod 302 is threadedly connected to a nut seat 303, and the nut seat 303 fits into the bottom end face of the adjustment seat 301. By rotating the nut seat 303 along the outer wall of the threaded rod 302, the nut seat 303 pushes the adjustment seat 301 to move toward the mounting seat 2.

[0031] A connecting seat 408 is fixedly connected to the outer wall of the mounting seat 2 and the adjusting unit 3 .

[0032] A rotating rod 407 is rotatably connected to the inner wall of the connecting seat 408, and one side corresponding to the multiple rotating rods 407 is rotatably connected to the rotating seat 404. By adjusting the distance between the seat 301 and the mounting seat 2, the two connecting seats 408 move toward each other. At this time, the connecting seat 408 drives the rotating rod 407 to rotate, and at this time, the rotating rod 407 pushes the rotating seat 404 to move, adjusting the contact wheel 401 on the rotating seat 404 to move, so that the contact wheel 401 contacts and squeezes the pipe.

[0033] A spring 405 is fixedly connected to the outer wall of the rotating seat 404, and the other end of the spring 405 is fixedly connected to the moving seat 402. When the rotating rod 407 rotates, it pushes the rotating seat 404 to move outward. At this time, the rotating seat 404 drives the spring 405 and the moving seat 402 to move. The spring 405 is sleeved on the outer wall of the sliding rod 403. When the rotating seat 404 moves, the sliding rod 403 and the spring 405 move, driving the moving seat 402 and the contact wheel 401 to move.

[0034] The side of the sliding rod 403 away from the moving seat 402 is fixedly connected to the limiting seat 406 , and the limiting seat 406 is in contact with the rotating seat 404 .

[0035] The movable seat 402 is rotatably connected to the contact wheel 401. When the contact wheel 401 contacts the inner wall of the pipe, the contact wheel 401 pushes the movable seat 402 and the sliding rod 403 to move, so that the sliding rod 403 slides along the inner wall of the rotating seat 404. At the same time, the spring 405 is compressed. Under the rebound of the spring 405, the contact wheel 401 contacts the pipe. Under the squeezing of multiple contact wheels 401, the temperature sensor 1 is confined to the center position inside the pipe, which facilitates the temperature sensor 1 to perform online temperature measurement of the inner wall of the pipe, and the temperature measurement is accurate.

[0036] A plurality of pulling rings 5 ​​are fixedly connected to the outer wall of the mounting base 2. By connecting the rope to the pulling ring 5, the mounting base 2 can be conveniently pulled to move on the pipeline, so that the temperature sensor 1 is in a suitable position on the pipeline, which is convenient for online monitoring of the inner wall temperature of the pipeline.
