Description

Technical Field

[0001] The utility model belongs to the technical field of fire smoke exhaust equipment, and in particular relates to a wind pipe opening sealing device structure. Background Art

[0002] At present, the smoke exhaust duct openings of traditional fire smoke exhaust systems and clean air conditioning systems are usually directly connected to the outside world, which causes the hot air in the duct to come into contact with the cold air outside and easily forms condensation in the duct, seriously affecting the normal operation of the system; the existing technology adds electric valves, check valves and other measures in the middle of the duct, which are cumbersome to install and disassemble, and inconvenient for daily maintenance, with a high failure rate, and cannot effectively solve the condensation problem at the duct opening, especially for fire smoke exhaust systems with higher requirements. Condensation at the duct opening will bring great hidden dangers to the normal operation of the system. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a duct opening sealing device structure, which is easy to arrange and install, and convenient to maintain, and can effectively block outdoor cold air from entering the smoke exhaust duct opening, thereby reducing the occurrence of condensation in the duct.

[0004] The technical solutions adopted by the present invention to solve the above technical problems are:

[0005] A duct opening sealing device structure, comprising a sealing frame 5 arranged around the outer ring of the duct opening to be sealed 4, a sealing groove 6 being formed on the end surface of the sealing frame 5 flush with the duct opening to be sealed 4, and a sealing ring being arranged in the sealing groove 6;

[0006] The sealing frame 5 on one side of the air duct opening 4 to be sealed is installed with a driving mechanism 1, and the driving mechanism 1 is connected to the anti-leakage sealing soft curtain 3 through a telescopic actuator 2. The extension size of the anti-leakage sealing soft curtain 3 is adapted to the air duct opening 4 to be sealed, and the driving mechanism 1 is electrically connected to the fire alarm device.

[0007] Furthermore, the driving mechanism 1 is specifically an electric telescopic cylinder installed on the sealing frame 5 on one side of the air duct opening 4 to be sealed, and the telescopic actuator 2 is specifically a telescopic rod driven by the electric telescopic cylinder.

[0008] Furthermore, one end of the telescopic actuator 2 is connected to the driving mechanism 1 , and the other end is connected to the end of the anti-leakage sealing soft curtain 3 .

[0009] Furthermore, the telescopic actuator 2 is driven by the driving mechanism 1 to drive the anti-leakage sealing soft curtain 3 to extend from one side of the air duct opening 4 to be sealed to the other side until it covers the air duct opening 4 to be sealed.

[0010] Furthermore, the telescopic actuators 2 are provided in two groups, and the two groups of telescopic actuators 2 are symmetrically arranged on the upper and lower sides of the air duct opening 4 to be sealed.

[0011] Furthermore, the anti-leakage sealing soft curtain 3 is made of polyester fiber material.

[0012] Furthermore, the anti-leakage sealing soft curtain 3 extends to cover the air duct opening 4 to be sealed and forms a sealing fit with the sealing ring provided in the sealing groove 6 .

[0013] Compared with the prior art, the present invention has the following main advantages:

[0014] 1. The utility model provides a duct opening sealing device structure. By arranging a sealing frame and a sealing groove on the outer ring of the duct opening to be sealed and cooperating with a driving mechanism, a telescopic actuator and an anti-leakage sealing soft curtain, it can effectively block outdoor cold air from entering the exhaust duct opening, thereby reducing the occurrence of condensation in the duct.

[0015] 2. The sealing frame, sealing groove, driving mechanism, telescopic actuator and anti-leakage sealing soft curtain of the utility model are all arranged outside the air duct opening to be sealed, which is convenient for arrangement, installation and maintenance;

[0016] 3. The utility model is easy to operate. Under non-fire conditions, the anti-leakage sealing soft curtain is stretched to cover the air duct opening, and cooperates with the sealing frame and sealing groove to form a seal, thereby effectively blocking the air duct opening to be sealed; under fire conditions, the driving mechanism receives a signal and can promptly retract the anti-leakage sealing soft curtain, thereby not affecting the normal operation of the fire smoke exhaust system.
