[0023] The on-line monitoring device for cable tunnels provides three implementation modes:

The top of the inner wall of the protection box 31 is rotatably connected to a bidirectional threaded rod 35 through two left and right bearing seats. A second gear 36 is fixedly connected to the middle position of the surface of the bidirectional threaded rod 35. The second gear 36 penetrates through the protection box 31 and the motor box 32 and extends into the interior of the motor box 32. The second gear 36 is meshed and driven with the first gear 34. Both sides of the surface of the bidirectional threaded rod 35 are threadedly connected with L-shaped sliding sleeves 37.

Two left and right support boxes 38 are fixedly connected to the bottom of the protection box 31. An electric push rod 39 is fixedly connected to the top of the inner wall of the left support box 38. The output end of the electric push rod 39 is fixedly connected to a connecting rod 310.

The other end of the connecting rod 310 is slidably connected to the left side of the right support box 38. A temperature sensor 311 is fixedly connected to the connecting rod 310.

[0025] The mobile adjustment component 4 includes two left and right clamping arms 41.

[0026] The temperature monitoring mechanism 3 is installed on the track 2 by moving and adjusting the component 4 and the internal bidirectional threaded rod 35, making it convenient for the temperature monitoring mechanism 2 to be installed and disassembled, and it can move along the path of the cable laying, so that the temperature of each part of the cable can be monitored at any time for a long time, improving the comprehensiveness and reliability of the cable temperature monitoring.

[0027] As Figure 2 The second embodiment is shown. The main difference from the first embodiment is that: the fire extinguishing component 5 includes a water tank 51, the water tank 51 is fixedly connected to the left side of the bottom of the protection box 31, a water pump 52 is fixedly connected to the right side of the inner wall of the water tank 51, the water outlet of the water pump 52 is connected to a connecting hose 53, the connecting hose 53 penetrates through the water tank 51 and extends to the outside of the water tank 51, and one end of the connecting hose 53 located outside the water tank 51 is connected to a nozzle 59.

[0028] The water outlet of the nozzle 59 is fixedly connected to an equalizing disc 591, a worm fan blade 593 is rotatably connected to the bottom of the inner wall of the equalizing disc 591, and a plurality of through holes 592 are formed in the bottom of the equalizing disc 591.

[0029] A slide bar 54 is fixedly connected between the left and right sides of the inner wall of the left support box body 38. The surface of the slide bar 54 is slidably connected with an L-shaped bracket 56. A return spring 55 is sleeved on the surface of the slide bar 54 on the left side of the L-shaped bracket 56. The L-shaped bracket 56 penetrates through the support box body 38 and extends to the outside of the support box body 38. The bent end of the L-shaped bracket 56 faces to the right. A first wedge block 57 is fixedly connected to the top of the bent part of the L-shaped bracket 56. A second wedge block 58 that cooperates with the first wedge block 57 is fixedly connected to the left side of the temperature sensor 311.

[0030] Through the set fire extinguishing component 5, when an open fire is generated on the surface of the cable due to overheating, the part where the open fire is generated is quickly extinguished, improving the safety of cable use.

[0031] As Figure 4 The third embodiment is shown. The main difference from the second embodiment is that: the temperature safety protection system 7 includes a temperature information reading module 71, a temperature information analysis module 72, a temperature information filtering module 73 and a temperature information sending module 74. The signal output end of the temperature information reading module 71 is connected to the signal input end of the temperature information analysis module 72. The signal output end of the temperature information analysis module 72 is connected to the signal input end of the temperature information filtering module 73. The signal output end of the temperature information filtering module 73 is connected to the signal input end of the temperature information sending module 74. The temperature sensor 311 and the processing module 6 are connected bidirectionally. The processing module 6 and the Internet transmission module 8 are connected bidirectionally. The Internet transmission module 8 and the cloud 9 are connected bidirectionally. The cloud 9 and the online terminal 10 are connected bidirectionally.

[0032] The passed temperature safety protection system 7 analyzes the cable temperature information monitored by the temperature monitoring mechanism 3, extracts the data with abnormal temperatures at multiple points of the cable, and transmits the abnormal parts to the online terminal for the convenience of the staff to observe.

[0033] After the track 2 is installed, place the left and right clamping arms 41 on the left and right sides of the track 2. Start the adjustment motor 33. The rotation of the adjustment motor 33 drives the first gear 34 to rotate. The first gear 34 rotates and transmits the power to the second gear 36. The rotation of the second gear 36 causes the bidirectional threaded rod 35 to rotate. The rotation of the bidirectional threaded rod 35 makes the two L-shaped sliding sleeves 37 approach each other, thereby driving the left and right clamping arms 41 to approach the left and right sides of the track 2, so as to clamp on the left and right sides of the track 2. In addition, the height distance between the temperature sensor 311 and the cable can be adjusted by tightening the locking bolt 44. In addition, start the drive motor 42. The rotation of the drive motor 42 makes the roller 43 rotate. The rotation of the roller 43 drives the entire temperature monitoring mechanism 3 to move, so as to monitor the temperature of the cable surface through the temperature sensor 311 during the movement. The data monitored by the temperature sensor 311 is sent to the temperature safety protection system 7 through the processing module 6. The temperature information reading module 71 reads the transmitted temperature data, and the temperature information analysis module 72 analyzes the read information, analyzes the abnormal parts and temperature information of the problems, filters out the abnormal data through the temperature information filtering module 73, and sends the abnormal data to the Internet transmission module 8 through the temperature information sending module 74. The Internet transmission module 8 then sends the data to the online terminal 10 through the cloud 9. In addition, when the temperature data is abnormally large, it is judged that there is an open fire. At this time, control the electric push rod 39 to start, so that the temperature sensor 311 moves upward. The upward movement of the temperature sensor 311 drives the second wedge block 58 to move upward, so that the L-shaped bracket 56 can move to the right under the action of the return spring 55, and start the water pump 52 to pump the water in the water tank 51 to the nozzle 59. The water enters the nozzle 59 and makes the worm fan blade 593 rotate, so that the water can be evenly sprayed on the cable surface to extinguish the fire on the cable.
