Fireproof smoke-isolating fire-fighting roller shutter door
The invention discloses a fireproof and smoke-isolating type fire-fighting rolling shutter door applied to the field of fire-fighting devices, when a fire occurs, a fire-fighting fireproof shutter door is put down for fireproof isolation, a thermal deformation air bag can expand and push an outer movable sealing strip to be attached to the two sides of the shutter door through a movable push plate to achieve primary sealing and smoke isolation, and meanwhile, the outer movable sealing strip is pushed to be attached to the two sides of the shutter door; the first magnetic repulsion block and the magnetic movable plate are the same in magnetism, so that magnetic thrust is generated on the magnetic movable plate, stable extrusion force is applied to the inner movable flexible sealing strip, the soft inner movable flexible sealing strip can be better attached to the surface of the curtain door, and when the curtain door deforms, the inner movable flexible sealing strip can be tightly attached to the surface of the curtain door. When the inner movable flexible sealing strip is pressed, the inner movable flexible sealing strip can correspondingly deform under the action of magnetic thrust so as to effectively guarantee the sealing smoke isolation effect, and when the inner movable flexible sealing strip is attached to the curtain door, the multiple smoke isolation sealing layers on the inner movable flexible sealing strip can be tightly attached to the curtain door in the pressed state, so that multiple sealing cavities are formed, and therefore the sealing effect of the curtain door is improved. And the smoke isolation effect is further improved.
本申请公开了应用于消防装置领域的一种防火隔烟型消防卷帘门，当发生火情时，将消防防火帘门放下进行防火隔离，热形变气囊会膨胀并通过活动推板推动外活动密封条与帘门两侧贴合实现初步密封隔烟，同时，第一磁性相斥块和磁性活动板磁性相同，故对磁性活动板产生磁性推力，为内活动柔性密封条施加稳定的挤压力，使较为柔软的内活动柔性密封条能更好的与帘门表面贴合，故当帘门发生形变时，内活动柔性密封条在磁力推力的作用下也会相应发生形变，以有效保证密封隔烟效果，并且当内活动柔性密封条与帘门贴合时，内活动柔性密封条上的多个隔烟密封层在受压状态下会与帘门紧密贴合，从而形成多个密封腔，进一步提升隔烟效果。
