In addition, in the actual use process of facilities such as the existing fireproof roller shutter door, the lowering speed is low, gaps are often reserved, the top sealing performance of the roller shutter door is poor, and dense smoke generated by a fire disaster cannot be completely isolated. These facilities also fail to automatically extinguish and isolate the primary fire.
Disclosure of Invention
The invention aims to provide a free separation type flexible partition fire-fighting system, which forms a fireproof partition wall for a small space range of a fire point in time when a fire hazard occurs in a building, prevents the fire from channeling four, and reduces loss.
To solve the above problems, a first aspect of the present invention provides a flexible zoned fire protection system, comprising: a plurality of fire detectors and a plurality of airbag assemblies are arranged in the building to form/form a freely separated flexible zoned fire space, wherein the fire detectors are connected with the airbag assemblies through wires or control devices; the airbag module includes: a housing having at least one movable opening; an air bag made of high temperature resistant material and placed in the interior of the shell body; an expansion device for receiving signals from the fire detector or control device to rapidly expand the airbag.

The fire detector can also send signals to the control device, and the signals are processed by the control device and then sent to the air bag assembly. The air bag can isolate air after being inflated, and the rapid spreading of the fire point is prevented. Compared with a fireproof door, the fire extinguishing system provided by the embodiment has the advantages that the response speed is faster, the space can be separated more finely, the reliability is higher, the maintenance is convenient, and the loss can be reduced when a fire disaster occurs. And personnel can squeeze through from gasbag and wall body or gasbag and gasbag, and the gasbag can resume the normal position through the location magnetic path after personnel pass, keeps on keeping apart the ignition point, can not destroy the closure of gasbag to the ignition point. The air bag can generate external extrusion force through internal air pressure, so that the tightness can be improved. Wherein the fire detector may be: a smoke detector, a temperature detector, a flame detector, and a special gas detector; ion type detector, photoelectric detector; linear detectors, spot detectors, cable detectors, infrared beam detectors, including but not limited to the examples described above. The fire detector can be used singly or in combination. The fire scene temperature is about 400 ℃, and the air bag can be made of high temperature resistant materials, wherein the high temperature resistant materials comprise but are not limited to refractory fibers and refractory silica gel tapes. The airbag materials are rotated by the materials piled up on site, so that the airbag can work for a long time in a fire scene.

The exterior of the flexible air bag can also be partially coated or coated with a fire-resistant coating to enable the air bag to meet the safety requirements of being in direct contact with a fire point, wherein the fire-resistant coating comprises, but is not limited to, phenolic-based fire-resistant coating, latex fire-resistant coating, polyvinyl acetate emulsion-based fire-resistant coating, room-temperature self-drying water-soluble expansion fire-resistant coating, polyolefin fire-resistant insulating coating, modified high-chlorine polyethylene fire-resistant coating, chlorinated rubber expansion fire-resistant coating, fire-proof coating, foaming fire-resistant coating and wire and cable fire-resistant coating.
The further technical proposal is that a positioning magnetic block which is used for keeping the relative positions of the two air bags and is fixed in a sealing way can be arranged between the air bags and the building surface at the corresponding positions or between the air bags. The air bag is large in volume after being inflated, and position deviation possibly occurs, so that effective isolation of a fire point cannot be achieved. The positioning magnetic blocks can be respectively arranged on the surface of the building, the surface of the air bag or the inside of the air bag, and after the air bag is inflated, the relative positions of the air bags and the building are fixed through the mutual attraction between the positioning magnetic blocks. When a plurality of positioning magnetic blocks are required to be installed on the air bags, the air bags can be attracted to each other in the shell, so that the air bags can not be inflated smoothly, at the moment, the air bags can be installed with materials which can be attracted by the magnet as positioning blocks, and the positioning magnetic blocks are installed on the surfaces of other air bags or buildings to be matched with the air bags for positioning, so that the relative fixation of the positions between the air bags and between the air bags and the buildings can be achieved.
The door-shaped structure is arranged in a building, at least one or more air bag components are arranged at the position of the door-shaped structure, the position of the door-shaped structure can be sealed after the air bag is inflated, a free separated flexible partition fire-fighting space is formed, and personnel can squeeze through the inflated air bag butt joint. The positioning magnetic blocks are respectively arranged at the bottom of the air bag and on the building ground at the corresponding positions, and one or more groups of positioning magnetic blocks are also arranged between the air bag and the air bag for positioning. Fire roller doors are generally installed at locations within a building having a door-type structure to isolate a fire, and all personnel are required to be determined to evacuate before the fire is allowed to drop the fire roller doors, and the fire cannot be prevented from being retarded by isolating air. When a subsequent firefighter enters the interior of a building to extinguish the fire, the firefighting roller shutter door is often also required to be damaged violently. According to the embodiment, the building can be isolated when a fire is found through the flexible air bag structure, personnel can squeeze through the air bags, and the air bags can be restored to the original position through internal air pressure and the positioning magnetic blocks to continuously isolate the fire. The air bags can be printed with the mark sign for people evacuation, thereby facilitating people evacuation. The fire point is isolated through the gasbag, and its leakproofness is better than fire control rolling slats door, can isolate the air to a certain extent, prevents conflagration rapid development. When fire fighters enter the fire extinguishing device, the fire fighters can pass through the air bags, and can also release the gas in the air bags, so that the fire fighters can easily enter the fire range to extinguish the fire.
In a further technical scheme, a plurality of fire detectors and a plurality of air bag components are arranged on the ceiling in a lattice type alternately at a large space in a building with open four sides, and each fire detector is connected with the plurality of air bag components surrounding the fire detectors through wires or a control device. The air bags are blocks which are in contact with the ceiling and the floor after being expanded, and the air bags of a plurality of air bag assemblies around each fire detector can separate the open building space on four sides where the fire detector is positioned from other spaces after being expanded, so that a flexible zoned fire-fighting space is formed. The air bags are blocks which are contacted with the ceiling and the floor after being inflated, and the air bags of a plurality of air bag assemblies around each fire detector can separate the space where the fire detector is positioned from other spaces after being inflated. Wherein the number of air bag assemblies around each fire detector may be 3, 4, 6, including but not limited to the examples described above, and the fire detectors and air bag assemblies may be arranged according to the layout of ground items within the building. The air bags are expanded to form blocks contacted with the ceilings and the floors, so that flames and smoke can be prevented from diffusing from gaps of the ceilings or the floors, and gaps during surface contact reduction are formed by tightly contacting and pressing a plurality of air bags around the fire detector. After the air bag is expanded, the space where the fire detector is located can be separated from other spaces, the rapid diffusion of fire points is prevented, the effect of a fireproof door is achieved, and the influence of the content in the building on the isolation effect can be reduced due to the flexible characteristic of the air bag. And the fire door can not occupy space for installation and setting like a fire door, and cannot be closed in time due to the influence of contents. When a fire occurs, the fire detector directly or through the control device controls the air bag component, the air bag component opens the shell to release the air bags, the air bags are inflated, the inflated air bags surround the fire, the air bags and the ground are fixed by the positioning magnetic blocks, gaps are reserved between the air bags and the ground through air pressure in the air bags, good sealing performance is achieved, air around the fire is isolated, and further combustion of the fire is prevented. When the ignition point is in the expansion range of a certain air bag, the ignition point can be pressed and extinguished after the air bag is expanded, and a fire detector nearby the air bag can also detect the ignition point under the condition, so that surrounding air bag devices are further controlled to isolate the ignition point and prevent the ignition point from spreading, and the expanded air bag forms a structure which is shaped like a Chinese character 'tian' in the overlook view. And the arrangement of the fire detector and the airbag module on the ceiling of the building can effectively utilize the space. When a person is isolated in the space surrounded by several air bags at the same time in the vicinity of the fire, the person can squeeze out from between the air bags.
A further technical solution is that the expansion device comprises: one or more of an electric air pump, a compressed air bottle and an air bag detonating device. When the expansion device is an electric air pump, the air bag can be inflated, and the cost is reduced. The expansion rate of the bladder is faster when the expansion device is a compressed gas cylinder, wherein the liquefied gas in the compressed gas cylinder may be air, nitrogen, carbon dioxide, including but not limited to the examples described above. When the inflation device is an airbag squib, the inflation speed of the airbag can be further increased, wherein the airbag squib can use the airbag squib of the airbag. The electric air pump, the compressed air bottle and the air bag detonating device can be used in sequence or simultaneously by setting the use sequence, so that the expansion speed of the air bag is increased, and a fire source is isolated as soon as possible. The expansion device is preferably a compressed gas cylinder, and the compressed gas absorbs heat during gasification expansion and has a fire-point combustion inhibition effect.
The further technical proposal is that a shape memory skeleton made of shape memory steel wires is arranged in the air bag; the surface of the air bag is provided with an annular supporting bag body; the support bag body is provided with a unidirectional inflation inlet. The shape memory skeleton arranged in the air bag is made of shape memory steel wires, the shape after being unfolded can be memorized, after the shell of the air bag component is unfolded to release the air bag, the air bag rapidly pops open under the action of the restoring force of the shape memory skeleton, and the air bag is supported primarily, so that the air bag is inflated by the expansion device conveniently. The larger air bag can be rapidly expanded through the shape memory framework, and the response time after a fire is found is reduced. The shape memory skeleton can be including setting up the annular support circle at the gasbag both ends face and connecting the go-between of two annular support circles, and the shape memory skeleton not only can play the supporting role to the gasbag, can also restrict the gasbag and expand at the transition of non-working face, causes the waste of inflation time. The supporting bag body of the air bag is an annular auxiliary air bag arranged on the surface of the air bag, the supporting bag body is inflated by the inflation device to expand the supporting bag body, the effect of isolating a fire point can be achieved to a certain extent after the supporting bag body is expanded, and the supporting effect of the supporting bag body is more beneficial to the opening and expansion of other parts of the air bag. The unidirectional inflation port of the support bag body can prevent the gas of the support bag body from being lost, and can play a supporting role in the whole fire extinguishing process to isolate the fire.
The further technical proposal is that the expansion device injects carbon dioxide gas into the air bag, the bottom of the air bag is provided with an air overflow hole, and the carbon dioxide gas in the air bag can be discharged to the periphery after the air bag is fully expanded. The carbon dioxide gas can be flame-retardant, has a density heavier than that of air, can be discharged from the air bag to the periphery and then can be discharged from the bottom to the top, and the effect of rapidly controlling the fire condition is achieved. And need not set up other fire extinguishing systems or devices again, reduce cost, and simple structure can reduce the complexity of entire system to improve the reliability of system.
The further technical proposal is that the surface of the air bag is provided with a fire extinguishing medium release bag; after the air bag is inflated, the fire extinguishing medium is released to the periphery of the air bag, the fire extinguishing medium release bag is sealed by the plug pin, the pulling-out end of the plug pin is connected with the surface of the air bag, and the plug pin can be pulled out after the air bag is inflated. The fire extinguishing medium is directly arranged on the surface of the air bag, and the fire extinguishing medium can be directly released to extinguish the fire after the air bag is fully expanded, so that the fire disaster which occurs initially can be more rapidly extinguished in the reaction process is reduced. After the air bag isolates the fire starting point, the fire extinguishing medium is released to the periphery of the air bag after the air bag is inflated, so that the initially-occurring fire can be automatically extinguished, and the fire starting loss is greatly reduced. The fire extinguishing medium can be various existing fire extinguishing media which can be compressed in a small steel cylinder, including but not limited to: carbon dioxide, heptafluoropropane and pyro are preferably carbon dioxide. Can be compressed and mounted on the surface of the balloon, and released after the balloon is inflated.
Further technical proposal is that the surface of the air bag is coated with fireproof silica gel. Intumescent fire retardant coatings may also be applied. The expansion type fireproof paint expands and foams when heated to form a carbonaceous foam heat insulation layer to seal a protected object, delay the transfer of heat and a base material, and prevent the object from igniting and burning or reducing strength caused by temperature rise. The expansion type fireproof coating can further coat and seal the barrier which cannot be coated by the air bag in the expansion process, so that the sealing performance is improved.
