Free-separation-type flexible partitioning fire protection system

Abstract

The invention discloses a free-separation-type flexible partitioning fire protection system and relates to the technical field of fire protection facilities. The system comprises multiple fire detectors installed in a building and multiple airbag assemblies installed in the building to form a free-separation-type flexible partitioning fire protection space. The fire detectors are connected with the airbag assemblies through wires or control devices. Each airbag assembly comprises a shell, an airbag placed in the shell and made of a high-temperature-resistant material and an expansion device which receives signals of the fire detectors or the control devices to make the airbags quickly expand.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a free-separated flexible partition fire-fighting system. Background technique [0002] At present, the fire protection settings inside the building are mainly used for fire prevention and heat insulation at the larger openings of the building through safety doors, fire shutter doors, etc., which are widely used in fire partition areas of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. , is an indispensable fire prevention facility in modern buildings. Rigid fire safety doors have explosion-proof functions, but they are usually bulky and costly, and the effect is easily affected by poor timing of closing. At present, there is a kind of flexible fireproof shutter. When a fire occurs, the shutter sheet will sag under the action of gravity to form isolation, which is low in cost, easy to i...

AI Technical Summary

Problems solved by technology

Rigid fire safety doors have explosion-proof functions, but they are usually bulky and costly, and are likely to affect the effect due to poor timing of closing

At present, there is a kind of flexible fireproof shutter. When a fire occurs, the shutter sheet will sag under the action of gravity to form isolation, which is low in cost, easy to install, and easy to grasp when to cut off the smoke. The separation effect of combustion air is not ideal

[0003] Rolling shutters and other settings cannot divide the space in the building into small parts, and can only be set in special locations. Once a fire breaks out and the indoor fire hydrant system, foam fire extinguishing system or dry powder fire extinguishing system is activated, the items in the entire fire area will be damaged and cannot continue use

In addition, in the actual use of current fire-proof rolling doors and other facilities, the speed of lowering is slow, and there are often gaps left, resulting in poor sealing at the top of the rolling door, which cannot completely isolate the dense smoke generated by the fire.

These facilities also cannot automatically extinguish the initial fire and isolate the fire source.
