Civil air defense door with good heat preservation and heat insulation performance

Abstract

The invention discloses a civil air defense door with good heat preservation and heat insulation performance. The civil air defense door comprises a support external connection frame, wherein a fireproof heat preservation mechanism is fixedly installed in the support external connection frame, an automatic induction mechanism is movably arranged on the top of the support external connection frame, a sealing mechanism is movably arranged at the bottom of the support external connection frame, and a transmission mechanism is arranged between internal connection support frames and acts on a heat preservation sponge plate so as to prevent two-way evaporation of heat. When the weather is cloudy and humid, generated water vapor can be attached to the heat preservation sponge plate, redundant moisture is discharged through a plurality of air holes in the heat preservation sponge plate, the phenomenon of corrosion caused by water vapor accumulation is prevented, a door body fireproof structure is additionally arranged under the conditions, serious loss of door body structural components is prevented, additionally, the heat preservation performance of the door body is enhanced, heat volatilization is reduced, an existing mode of a mechanical door lock is replaced, internal elements are prevented from being aged and rusted, the opening and closing difficulty is not increased, and automatic scientific and technical development of the door body is also enhanced.

Description

technical field [0001] The invention belongs to the technical field of civil air defense doors, in particular to a civil air defense door with good thermal insulation performance. Background technique [0002] This type of door is the earliest to be finalized and has been widely used. It is characterized by simple structure, reliable operation and convenient maintenance, and is suitable for the entrance and exit of various civil air defense projects. However, because it has a threshold, it has been seldom used for projects with frequent personnel and vehicles, such as underground shopping malls combined in peacetime and wartime. [0003] Compared with ordinary doors and windows, civil air defense doors are larger in size and wider in thickness, and have multiple uses such as heat insulation and anti-theft. However, the existing civil air defense doors are used in a relatively closed environment, and the probability of fire increases during the process. The fire protection ...

Problems solved by technology

[0003] Compared with ordinary doors and windows, civil air defense doors are larger in size and wider in thickness, and have multiple uses such as heat insulation and anti-theft. However, the existing civil air defense doors are used in a relatively closed environment, and the probability of fire increases during the process. The fire protection effect is poor, and there is no good thermal insulation structure inside, resulting in weak indoor temperature storage capacity. Most of the existing civil air defense doors use mechanical door locks. After long-term use, the internal structure will age and corrode, resulting in poor flexibility. Increasing the difficulty of opening and closing is not conducive to the technological environment of the current developed society. In the process of fire, the existing civil air defense doors cannot eliminate the gap between the door and the door frame, resulting in thick smoke entering the room and reducing the prevention effect
