[0032] The sealing detection mechanism 04 includes a detection upper half box 41, a detection lower half box 42, a sealing piston 43, a first spring 44 and a proximity switch 45. The detection upper half box 41 and the detection lower half box 42 are fixedly installed on the outer walls of the first fire duct 11 and the second fire duct 12 through a fixing mechanism 05. The connecting mechanism 02 is wrapped by the detection upper half box 41 and the detection lower half box 42. The sealing piston 43 is slidably installed in the detection lower half box 42. One end of the first spring 44 is installed on the inner wall of the detection lower half box 42, and the other end of the first spring 44 is installed on the sealing piston 43.

Due to the thread relationship, the nut 24 drives to fix the two connecting plates 21, thus completing the connection of the first fireproof air duct 11 and the second fireproof air duct 12, improving the convenience. Connect the mounting ear 31 and the mounting plate 32 through the fixing bolt 33, support the first fireproof air duct 11 or the second fireproof air duct 12 through the mounting plate 32, and facilitate the hoisting of the first fireproof air duct 11 and the second fireproof air duct 12 through the hoisting rod 34. When the connection sealing performance of the first fireproof air duct 11 and the second fireproof air duct 12 decreases, the smoke enters the lower half of the detector 42, and then the sealing piston 43 is pushed by the air pressure to slide in the lower half of the detector 42, so that the sealing piston 43 approaches the proximity switch 45. The proximity switch 45 emits an electrical signal to drive the buzzer to alarm, reminding the operator to come for maintenance. A short-term emergency can also be carried out through the sealing of the upper half of the detector 41 and the lower half of the detector 42. When installing the upper half of the detector 41 and the lower half of the detector 42, pass the fixing pin 53 through the perforation on the second fixing plate 52. When the locking pin 56 aligns with the locking hole on the fixing pin 53, release the handle, and the elastic force of the second spring 57 pushes the locking pin 56 into the locking hole of the fixing pin 53, thus completing the fixation of the upper half of the detector 41 and the lower half of the detector 42.
