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.

Embodiment 1

[0053] A flexible partition fire protection system, such as figure 1 As shown, it is a three-dimensional schematic diagram of this embodiment, including several fire detectors 2 and airbag assemblies 3 arranged on the building ceiling 1; the fire detectors 2 and airbag assemblies 3 are alternately arranged in a dot matrix, and each fire detector 2 Surrounded by four airbag modules 3, the arrangement method is as follows figure 2 as shown, figure 2 It is a top view of the ceiling installed with the flexible partition fire protection system of this embodiment, showing four groups of fire detectors 2 and surrounding airbag assemblies 3, wherein the airbags 32 have been opened. It can be seen that after the airbag 32 is inflated, the space can be divided into isolated spaces 12 one by one, thereby preventing the spread of fire when a fire occurs. The airbag 32 is made of high-purity aluminum silicate refractory fiber, with a maximum service temperature of 1260°C and a long-ter...

Embodiment 2

[0056] A flexible partition fire protection system is installed at the entrance and exit of the building instead of the fire shutter door. Such as Figure 9 As shown, the height of the entrance and exit is 5.5 meters and the width is 3 meters. The airbag 32 is made of fire-resistant silica gel cloth, and the surface is coated with chlorinated rubber expansion fireproof paint. A top airbag assembly 322 is installed on the top of the entrance and exit, and a side airbag assembly 323 is installed on both sides respectively. After the airbag 32 is fully inflated, the contact line between the three airbags is "T" shape. Such as Figure 10 shown, for Figure 9 In the enlarged view of part C, the top airbag is equipped with a positioning magnetic block 321 between it and the two walls of the entrance and exit of the building. After the airbag 32 is put down and inflated, it will not deviate along the direction of the entrance and exit. Such as Figure 11 shown, for Figure 9 In...

Embodiment 3

[0059] A flexible partition fire protection system is installed at the entrance and exit of the building instead of the fire shutter door. Such as Figure 16 As shown, the height of the entrance and exit is 3.2 meters and the width is 6 meters. The airbag 32 is made of fire-resistant silicone cloth, and the surface is coated with polyvinyl acetate emulsion-based fireproof paint. A top airbag assembly 322 is installed on the top of the entrance and exit, and a side airbag assembly 323 is installed on both sides respectively. After the airbag 32 is fully inflated, there is a vertical contact line between the top airbag and the two side airbags. Such as Figure 17 and Figure 18 shown, respectively Figure 16 In the enlarged diagrams of parts E and F in the middle, the nickel-iron blocks 324 that cooperate with the positioning magnetic blocks 321 are installed in the top airbag, which are respectively arranged on the bottom and the side, and the matching positioning magnetic ...

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...
