The left end of the connecting pipe 11 is fixedly connected to a hose 12, and the left end of the hose 12 is fixedly connected to an intake pipe 13. The left end of the intake pipe 13 is located on the right side of the sealing plate 4 and extends to the outside thereof. The length of the hose 12 is relatively long and will not affect the movement of the sealing plate 4 on the right side. An air pressure sensor 100 is fixedly connected to the sealing plate 4 on the left side.

[0024] The top of the fixed shell 3 is provided with a mounting plate 14, the bottom of the mounting plate 14 is in contact with the top of the fixed shell 3, and two slots 15 are provided at the bottom of the front of the mounting plate 14. The top of the fixed shell 3 and the position corresponding to the slot 15 are fixedly connected with an insert 16. The top of the insert 16 passes through the slot 15 and extends to its interior and contacts the inner wall of the slot 15. A fixing groove 17 is provided on the top of the mounting plate 14. An adjusting rod 18 is rotatably connected to the groove at the bottom of the inner wall of the fixing groove 17 through a bearing. The top of the adjusting rod 18 passes through the slot 15. A rotating block 19 is fixedly connected to the fixed groove 17 and extends to the outside thereof. A movable plate 20 is threadedly connected to the surface of the adjusting rod 18. The surface of the movable plate 20 is in sliding contact with the inner wall of the fixed groove 17. A clamping block 21 is fixedly connected to the bottom of the movable plate 20 at the position corresponding to the insertion block 16. A clamping slot 22 is provided at the top of the insertion block 16 at the position corresponding to the clamping block 21. The bottom of the clamping block 21 passes through the fixed groove 17, the slot 15 and the clamping slot 22 from top to bottom in sequence and extends to the inside of the clamping slot 22 and contacts the inner wall of the clamping slot 22.

[0025] Through the mutual cooperation of the transparent water tank 2, the fixed shell 3, the sealing plate 4, the servo motor 5, the forward threaded rod 6, the reverse threaded rod 7, the threaded block 8, the adjustment plate 9, the air pump 10, the connecting pipe 11, the hose 12, the air pressure sensor 100, the air intake pipe 13 and the mounting plate 14, it is convenient to detect the airtightness of the drainage pipe, and the size of the leakage hole can be quickly understood, thereby improving the detection effect.

[0026] Through the mutual cooperation of the slot 15, the insert block 16, the fixed slot 17, the adjusting rod 18, the rotating block 19, the movable plate 20, the clamping block 21 and the clamping slot 22, it is convenient to disassemble the detection and clamping structure for maintenance and repair, thereby improving the flexibility during use.

[0027] Furthermore, two positioning rods 23 are fixedly connected to the bottom of the movable plate 20, and a positioning groove 24 is provided at the bottom of the inner wall of the fixed groove 17 and corresponding to the position of the positioning rod 23. The bottom end of the positioning rod 23 passes through the positioning groove 24 and extends to the inside to contact the inner wall of the positioning groove 24. By setting the positioning rod 23 and the positioning groove 24, the stability of the movable plate 20 during movement is improved.

[0028] Specifically, the rotating block 19 is rotated, and the rotating block 19 drives the adjusting rod 18 to rotate. The adjusting rod 18 drives the clamping block 21 to move upward through the movable plate 20, so that the clamping block 21 and the clamping slot 22 are separated. Then, the fixed shell 3 can be pulled forward, and the fixed shell 3 drives the plug-in block 16 to move forward, so that the plug-in block 16 and the slot 15 are separated. The structure on the fixed shell 3 can be disassembled for maintenance and repair.

[0029] Furthermore, the bottoms of the two opposite sides of the two sealing plates 4 are fixedly connected with top plates 25, and the tops of the top plates 25 are fixedly connected with arc-shaped support plates 26. By setting the top plates 25 and the arc-shaped support plates 26, the position of the pipeline between the two sealing plates 4 is improved. The left side of the top of the bottom plate 1 is fixedly connected with a connecting plate 27, and two cylinders 28 are fixedly connected to the connecting plate 27. The bottom ends of the cylinders 28 are fixedly connected to the top of the mounting plate 14, and the left side of the connecting plate 27 is fixedly connected with an alarm 29. By setting the alarm 29, it is possible to quickly understand whether the pipeline is leaking.

[0030] Furthermore, a controller is fixedly connected to the connecting plate 27 , and the servo motor 5 , the air pump 10 , the air cylinder 28 , the air pressure sensor 100 and the alarm 29 are electrically connected to the controller respectively.

[0031] When in use, the drainage pipe is placed on the top of the arc-shaped support plate 26 and located between the two sealing plates 4. Then the servo motor 5 is started. The servo motor 5 drives the forward threaded rod 6 and the reverse threaded rod 7 to rotate through the output shaft, so that the two threaded blocks 8 move closer to each other. The threaded block 8 drives the sealing plate 4 to move close to the drainage pipe through the adjustment plate 9, so that the two sealing plates 4 clamp and seal the two ends of the drainage pipe. Then the air pump 10 is started. The air pump 10 transmits gas to the drainage pipe through the air inlet pipe 13, and senses whether the air pressure in the drainage pipe is stable through the air pressure sensor 100. At the same time, the cylinder 28 is started. The cylinder 28 drives the fixed shell 3 and the drainage pipe to move to the inside of the transparent water tank 2. When the drainage pipe leaks, the position and size of the leak can be clearly seen through the transparent water tank 2. At the same time, the air pressure sensor 100 transmits the signal to the controller, and the controller activates the alarm 29 to sound an alarm to remind the staff.
