An anti-falling elastic clamping card plate 6 for limiting the position of the U-shaped card plate 4 is connected to the outer wall of the U-shaped card plate 4 below the thermal pipe body 1. The detection collar 2 is connected to the U-shaped card plate 4 through an L-shaped traction plate 13. An alarm 3 is installed on the top surface of the detection collar 2. The alarm 3 includes a buzzer and a warning light.

[0030] The detection collar 2 is composed of two oppositely arranged semicircular clamp rings 22 connected together, and an outer ring plate 24 is provided at the center of both sides of the two semicircular clamp rings 22. The inner walls of the two outer ring plates 24 are bonded with rubber sealing rings 25, and the inner walls of the rubber sealing rings 25 abut against the outer wall of the thermal pipe body 1;

[0031] Connecting plates 23 are provided on the outer walls of both ends of the two semicircular clamp rings 22, and two adjacent connecting plates 23 are connected by fixing bolts;

[0032] Two ear plates 8 are symmetrically welded on the top surface of the U-shaped card plate 4, and the handle rod 5 is fixedly installed between the two ear plates 8. A rectangular plug interface 11 is opened on one side of the U-shaped card plate 4, and the L traction plate 13 is inserted into the rectangular plug interface 11, and the U-shaped card plate 4 is connected to the L traction plate 13 through a second locking bolt 12.

[0033] A plurality of threaded holes 14 are equidistantly provided on the upper and lower sides of the side of the L-shaped traction plate 13 away from the rectangular plug-in port 11, and one of the threaded holes 14 is connected to the detection collar 2 by a screw.

[0037] Working principle:

[0038] The thermal pipeline leakage rapid detection device has a U-shaped card plate 4 clamped on one end of the outer wall of the thermal pipeline body 1, and a detection collar 2 installed on the other end of the outer wall of the thermal pipeline body 1. When the U-shaped card plate 4 and the detection collar 2 are fixedly installed, the two anti-falling elastic clamping cards 6 can be adjusted in distance from the horizontal plate 21 under the action of multiple tension springs 19. Under the action of the telescopic positioning rod 20, the position of the anti-falling elastic clamping cards 6 can be adjusted, and the tension spring 19 pulls the two anti-falling elastic clamping cards 6 inward to clamp and fix the U-shaped card plate 4.

[0039] When the U-shaped card plate 4 and the detection collar 2 need to be moved, the two anti-fall-off elastic clamping plates 6 are removed to separate them from the U-shaped card plate 4. When force is applied to the U-shaped card plate 4, the multiple clamping auxiliary rollers 16 can roll between two adjacent transverse plates 15, so that the U-shaped card plate 4 can move on the outer wall of the thermal pipe body 1, thereby adjusting its position.

[0040] The multiple gas sensors on the surface of the detection collar 2 can detect the thermal pipe body 1. If a gas leak occurs outside the thermal pipe body 1, the gas sensor will detect the gas pressure outside the thermal pipe body 1. When the change value exceeds the set safety value, the information will be immediately fed back to the PLC set in the detection collar 2. The PLC controls the alarm 3 to start and alarm.

[0041] The two detachable fixed vertical plates 7 can be installed by the cooperation between the extended insert plate 9 and the rectangular insert port 11 , and the extended insert plate 9 can be fixedly installed by the first locking bolt 10 .

Any technician familiar with this technical field can make equivalent substitutions or changes within the technical scope disclosed by the invention based on the technical solution and inventive concept of the invention, which should be covered by the scope of protection of the invention.
