Protective sealing door

Abstract

The invention provides a protective sealing door. The protective sealing door comprises a door body (1) and a door frame (7), a sealing groove (2) is formed in one of the door body (1) and the door frame (7), and a sealing strip (3) is arranged on the other one of the door body and the door frame in the mode of corresponding to the sealing groove (2); a sealing part (4) is arranged in the sealinggroove (2), when sealing is not needed, the sealing part (4) is in a natural state, and a gap is reserved between the sealing part and the sealing strip (3); when sealing is needed, the sealing part is inflated, sealing is formed between the sealing part and the sealing strip (3); and the sealing part (4) is connected with an air source and a controller (5), and the controller (5) controls the airsource to inflate or deflate the sealing part (4). According to the protective sealing door, effective sealing protection property can be provided, and the protective sealing door is effectively prevented from leakage.

Description

technical field [0001] The invention relates to the technical field of civil air protection engineering, in particular to a protective airtight door. Background technique [0002] Due to the entry and exit of personnel and equipment, as well as the needs of ventilation, water supply and drainage, and smoke exhaust, civil air defense fortifications in wartime have a small number of orifices that communicate with the outside. Explosion shock waves, poisons, biological warfare agents, and radioactive particles are all likely to enter the project through these openings to kill personnel and damage oral engineering structures and equipment. In order to avoid leakage incidents, protective airtight doors are generally installed at these openings. The size of the protective airtight door can be determined according to the demand. The conventional large protective airtight door can be divided into two. The total width of the protective airtight door can reach 7m. The height of the p...

AI Technical Summary

Problems solved by technology

[0003] The protective airtight door is the biggest leakage part of the civil air defense fortification. If the protective airtight door is not sealed properly, the air will enter / leak into the civil air defense fortification from the sealed part, which will pose a threat to the safety of personnel and equipment in the fortification.

[0004] However, the current effective sealing form of super large protective airtight doors is not ideal, and the traditional extrusion sealing form of small doors is not suitable for super large protective airtight doors, which is prone to leakage problems
