The technical field relates to fire protection assemblies, and more particularly to fire spread-limiting assemblies and to methods for limiting fire spread.
Firefighting is a battle against time: when a fire occurs, for instance and without being limitative in a building, in a vehicle or outside thereof, it is essential to quickly intervene so as to limit the damages as well as to limit fire from spreading around the initial fire. However, particularly when the fire occurs in remote locations, it might require some time for firemen to reach the fire. Moreover, existing firefighting devices that can be available for instance in a building or in a vehicle are not always easy to use and/or efficient.
In view of the above, there is a need for a fire spread-limiting assembly which would be able to overcome or at least minimize some of the above-discussed prior art concerns and would be able to quickly and efficiently limit the spreading of a fire and inhibit the formation of flame upon a structure or a location when exposed to the imminent threat of fire.

Referring now to the drawings, and more particularly to
As detailed below, the fire spread-limiting assembly 100 is configured to limit fire spread thanks to the cooling fluid circulating within the one or more flexible fluid lines 330.
In the embodiment shown, the cooling fluid designates a substance, typically liquid or gas, that is used to reduce or regulate the temperature of the fire spread-limiting assembly 100. For instance, the cooling fluid has high thermal capacity, low viscosity, is chemically inert and/or neither causes nor promotes corrosion of the cooling fluid circulation assembly 300. For instance, the cooling fluid comprises water, polyalkylene glycol or any other fluid having coolant materials.
Heat Resistant Covering
In the embodiment shown, as represented for instance in
In the embodiment shown, as represented in
For instance, at least one of the first and second heat resistant layers 210, 220 is at least partially made of a material having mechanical and/or heat-resisting properties. For instance, at least one of the first and second heat resistant layers 210, 220 is at least partially made of fiberglass, Kevlar™, carbon fiber or a combination thereof. The first and second heat resistant layers 210, 220 might have a substantially similar structure and/or composition or could be made of different materials.
The first and second heat resistant layers 210, 220 each comprise an inner face 212, 222, and an opposed outer face 214, 224. The inner faces 212, 222 of the first and second heat resistant layers 210, 220 at least partially face each other.
In the embodiment shown, and as represented in
In the embodiment shown, the cooling fluid source 310 is at least partially delimited by at least one of the first and second heat resistant layers 210, 220 of the heat resistant covering 200. In the embodiment shown, the first and second heat resistant layers 210, 220 are joined to each other at a lower portion thereof. For instance, the first and second heat resistant layers 210, 220 are made of a single layer 215 folded along a central portion thereof forming a lower portion 217 of the heat resistance covering 200. The term “lower portion” equally refers to the first and second heat resistant layers 210, 220, to the heat resistant covering 200, or to any other component of the heat resistant covering 200. It could also be conceived a heat resistant covering that would be made of two distinct first and second heat resistant layers that would be secured to each other (for instance glued, welded or sewn to each other).
In the embodiment shown, the cooling fluid source 310 is at least partially formed by folding the single layer 215 forming the first and second heat resistant layers 210, 220. For instance, the cooling fluid source 310 could be at least partially formed or delimited by folding at least one of the first and second heat resistant layers 210, 220. In the embodiment shown, the cooling fluid source 310 is at least partially delimited or formed by the inner faces 212, 222 of the first and second heat resistant layers 210, 220. It could also be conceived a fire spread-limiting assembly 100 in which the cooling fluid source 310 would only be limited by the inner face 212, 222 of a single one of the first and second heat resistant layers 210, 220, the single one of the first and second heat resistant layers 210, 220 being folded on itself.
In the embodiment shown, as represented in
For instance, the first and second absorbing material layers 231, 233 are at least partially made of foam, fabrics or any other material having fluid-absorbing properties and/or heat-resisting properties.
In the embodiment shown, the heat resistant covering 200 further comprises first and second water resistant layers 240, 250 (or inner and outer water resistant layers 240, 250, considered with respect to the object, building, person, . . . substantially covered by the heat resistant covering 200, when configured in the extended configuration). The absorbing material layer 230 is arranged between the first and second water resistant layers 240, 250 (for instance between inner faces thereof).
In the embodiment shown, the first and second water resistant layers 240, 250 are made of a single water resistant layer 245 folded along a central portion thereof forming the lower portion of the first and second water resistant layers 240, 250. It could also be conceived a heat resistant covering that would be made of two distinct first and second water resistant layers. The two distinct first and second water resistant layers could be secured to each other (for instance glued, welded or sewn to each other) at a lower portion thereof.
In the embodiment shown, the cooling fluid source 310 is thus at least partially delimited (or formed) by the first and second water resistant layers 240, 250 of the heat resistant covering 200.
For instance, at least one of the first and second water resistant layers 240, 250 is at least partially made of fiberglass, Kevlar™, carbon fiber or a combination thereof. The first and second water resistant layers 240, 250 might have a substantially similar structure and/or composition or could be made of different materials.
In the embodiment shown, the first water resistant layer 240 and the first heat resistant layer 210 are made of distinct layers superposed to each other (for instance at least partially secured to each other, for instance by being glued, welded, sewn, . . . to each other). It could also be conceived a heat resistant covering in which the first water resistant layer and the first heat resistant layer would be made of a single layer having mechanical and/or heat-resisting properties and fluid-absorbing properties. The same considerations apply to the second water resistant layer 250 and the second heat resistant layer 220.
As mentioned above, and as represented in
It is thus understood that, in the embodiment shown, the flexible fluid lines 330 are secured to the first and second heat resistant layers 210, 220 via the absorbing material layers 231, 233 and the first and second water resistant layers 240, 250.
It is appreciated that the shape, and the configuration of the heat resistant covering, for instance, the shape, the number, the configuration, the structure of the first and second heat resistant layers, the first and second water resistant layers and the first and second absorbing material layers can vary from the embodiment shown.
Cooling Fluid Circulation Assembly
Cooling Fluid Source
As mentioned above, the cooling fluid source 310 is integrated to the heat resistant covering 200, to the lower end portion 217 thereof, in the embodiment shown. The term “integrated” should be understood as meaning that the cooling fluid source 310 is united with the heat resistant covering 200 (i.e. the cooling fluid source 310 is not spaced apart from—or at a distance of—the heat resistant covering 200). In the embodiment shown, the cooling fluid source 310 is mounted to the lower end portion 217 of the heat resistant covering 200.
The cooling fluid source 310 is further fluidly connected to the flexible fluid lines 330 and to the absorbing material layer 230.
It is appreciated that the shape, the configuration, and the location of the cooling fluid source 310 can vary from the embodiment shown.
Flexible Fluid Lines
In the embodiment shown, the flexible fluid lines 330 comprise a main distribution line 332 extending substantially between the upper and lower edge portions 204, 202 of the heat resistant covering 200, for instance substantially parallel to the first and second lateral portions 206, 208 when the heat resistant covering 200 is configured in the extended configuration. In the embodiment shown, the main distribution line 332 extend substantially in a central portion 201 of the heat resistant covering 200.
The flexible fluid lines 330 further comprise a plurality of secondary distribution lines 334 (three, in the embodiment represented in
In the embodiment shown, as represented in
As represented in
The present disclosure is not limited to flexible fluid lines 330 having perforations formed therein. It could also be conceived a fire spread-limiting assembly having flexible fluid lines with at least some areas made of a permeable or porous material, for the cooling fluid circulating into the flexible fluid lines to escape therefrom so as to circulate into the absorbing material layer surrounding the flexible fluid lines.
Moreover, the cooling fluid source 310 is in fluid communication with the absorbing material layer 230 of the heat resistant covering 200 for the cooling fluid circulating into the absorbing material layer 230 to be at least partially collected into the cooling fluid source 310 under the force of gravity and/or upon actuation of the pump 360. To this end, perforations 311 can be formed in the cooling fluid source 310, as represented in
It is appreciated that the shape, the configuration, and the location of the flexible fluid lines 330, for instance the shape, the configuration, the location and the number of the main and secondary distribution lines 332, 334 can vary from the embodiment shown.
Additional Features of the Cooling Fluid Circulation Assembly
As represented in
The fluid-cooling device 370 is configured to maintain a temperature of the circulating cooling fluid below a pre-determined temperature limit. The fluid-cooling device 370 could be permanently fluidly connected to the cooling fluid source 310, or selectively connected to the cooling fluid source 310, for instance only when a temperature of the cooling fluid circulating in the cooling fluid circulation assembly 300 is equal to or greater than a pre-determined threshold.
In the embodiment shown, as represented in
In the embodiment shown, the fire spread-limiting assembly 100 further comprises a cooling fluid controller 410 configured to monitor a heating condition of the fire spread-limiting assembly 100. For instance, the cooling fluid controller 410 is configured to monitor the temperature of the circulating cooling fluid (for instance the temperature of the cooling fluid circulating in the cooling fluid source 310).
The cooling fluid controller 410 is further configured to fluidly connect the complementary cooling fluid tank 400 to the cooling fluid circulation assembly 300 when the monitored heating condition corresponds to a pre-determined heating condition. For instance, the cooling fluid controller 410 is configured to fluidly connect the complementary cooling fluid tank 400 to the cooling fluid circulation assembly 300 when the temperature of the cooling fluid reaches a pre-determined temperature. The cooling fluid controller 410 is thus operatively coupled to the cooling fluid circulation assembly 300 (for instance to the cooling fluid source 310 thereof) and to the complementary cooling fluid tank 400.
In the embodiment shown, the fire spread-limiting assembly 100 further comprises a pump controller 420 configured to monitor a fire condition and to actuate the pump 360—or to adjust an actuation parameter of the pump 360—of the cooling fluid circulation assembly 300 when the monitored fire condition corresponds to a pre-determined fire condition. For instance, the pump controller 420 is configured to monitor a temperature in the vicinity of the heat resistant covering 200 or an atmosphere composition in the vicinity of the heat resistant covering 200 and to actuate the pump 360 when the temperature reaches a pre-determined fire temperature and/or when the atmosphere composition corresponds to a pre-determined fire atmosphere composition.
For instance, the pump controller 420 is configured to monitor a heating condition of the fire spread-limiting assembly 100 (for instance to monitor a temperature in the vicinity of the fire spread-limiting assembly 100) and to modify a flow rate of the pump 360 when the monitored heating condition corresponds to a pre-determined heating condition. In other words, the pump controller 420 is configured to adjust the flow rate of the circulating cooling fluid upon monitoring of the heating condition of the fire spread-limiting assembly 100. The pump controller 420 is thus operatively coupled to the cooling fluid circulation assembly 300 (for instance to the pump 360 thereof).
It is appreciated that the shape, the configuration, and the location of the complementary cooling fluid tank, the cooling fluid controller and the pump controller can vary from the embodiment shown.
Additional Features of the Fire Spread Limiting Assembly
As represented in
In the embodiment shown, the deployment device 500 comprises a plurality of extendable support members 510 (two, in the embodiment shown) mounted to the heat resistant covering 200 (for instance to the outer face 214, 224 of one of the first and second heat resistant layers 210, 220 or between the inner faces 212, 222 of the first and second heat resistant layers 210, 220). In the embodiment shown, each of the extendable support members 510 comprises an upper end portion 512 mounted to the upper edge portion 204 (or in the vicinity thereof) of the heat resistant covering 200, and an opposed lower end portion 514 mounted to the lower edge portion 202 (or in the vicinity thereof) of the heat resistant covering 200. In the embodiment shown, the extendable support members 510 extend along a substantially vertical direction.
In the embodiment shown, the extendable support members 510 are of the parallelogram type. It could also be conceived extendable support members of the scissor type or any other mechanical structure (such as, for instance, a shutter) mountable to the heat resistant covering 200 to configure the heat resistant covering 200 from one of the compact, extended and intermediate configurations into another one of the compact, the extended and the intermediate configurations.
The fire spread-limiting assembly 100 further comprises a deployment controller 430 configured to monitor a fire condition and to actuate the deployment device 500 when the monitored fire condition corresponds to a pre-determined fire condition. Similarly to the above-disclosed cooling fluid controller 410 and pump controller 420, the deployment controller 420 can be configured to monitor a temperature in the vicinity of the heat resistant covering 200 or an atmosphere composition in the vicinity of the heat resistant covering 200 and to actuate the deployment device 500 when the temperature reaches a pre-determined fire temperature and/or when the atmosphere composition corresponds to a pre-determined fire atmosphere composition. The deployment controller 430 is thus operatively coupled to the deployment device 500.
It is appreciated that the shape, the configuration, the structure and the location of the deployment device 500, for example the shape, the configuration, the number, the structure and the location of the extendable support members 510, can vary from the embodiment shown.
For instance, as represented in
The fire spread-limiting assembly can further comprise a mobile structure (not represented) supporting the heat resistant covering 200 and comprising for instance wheels or any other displacement devices. The mobile structure is thus configured to displace the fire spread-limiting assembly 100 (for instance to store it when not in use or to approach it from the fire for the heat resistance covering 200 to be configured in the extended configuration).
It is appreciated that the shape, the configuration, and the structure of the fire spread-limiting assembly 100 can vary from the embodiment shown. For instance, the shape, the configuration, and the dimensions of the heat resistant covering can be adjusted as a function of the location where the fire spread-limiting assembly is intended to be used and/or of the shape and dimensions of the building or object the heat resistant covering is configured to at least partially cover.
The present disclosure also concerns a method for limiting a spread of a fire. The method according to embodiments of the present disclosure may be carried out with a fire spread-limiting assembly such as those described above.
The method comprises covering and/or confining at least partially the fire with a heat resistant covering 200 of a fire spread-limiting assembly 100 and actuating a pump 360 of a cooling fluid circulation assembly 300 of the fire spread-limiting assembly 100 fluidly connected to a cooling fluid source 310 of the cooling fluid circulation assembly 300. The cooling fluid source 310 is integrated to the heat resistant covering 200 and to one or more flexible fluid lines 330 being part of the heat resistant covering 200 for the cooling fluid to circulate within the one or more flexible fluid lines 330.
It is thus understood that the pump 360 drives the cooling fluid from the cooling fluid source 310 to the one or more flexible fluid lines 330 (i.e. the pump 360 circulates the cooling fluid contained in the cooling fluid source 310 within the one or more flexible fluid lines 330 upon actuation).
In the embodiment shown, the method further comprises flowing the cooling fluid into an absorbing material layer 230 of the heat resistant covering 200. For instance, in the embodiment shown, upon actuation of the pump 360, the cooling fluid is circulated from the one or more flexible fluid lines 330 into the absorbing material layer 230 via perforations 336 formed in at least some of the flexible fluid lines 330. In the embodiment in which the heat resistant covering 200 comprises first and second heat resistant layers 210, 220, upon actuation of the pump 360, the cooling fluid will at least partially reach the first and second heat resistant layers 210, 220.
Moreover, the cooling fluid is further circulated, in particular under the force of gravity, into the cooling fluid source 310, for instance via perforations 311 formed therein.
In the embodiment shown, the method further comprises providing the heat resistant covering 200 into a compact configuration, monitoring a fire condition (such as a temperature in the vicinity of the heat resistant covering 200 or an atmosphere composition in the vicinity of the heat resistant covering 200), and configuring the heat resistant covering 200 into an extended configuration when the monitored fire condition corresponds to a pre-determined fire condition.
In the embodiment shown, the method further comprises monitoring a heating condition of the fire spread-limiting assembly (such as a temperature of the heat resistant covering 200 or of the cooling fluid circulating within the flexible fluid lines 330), and fluidly connecting a complementary cooling fluid tank 400 to the cooling fluid circulation assembly 300 when the monitored heating condition corresponds to a pre-determined heating condition.
In the embodiment shown, the method further comprises monitoring a fire condition (such as a temperature in the vicinity of the heat resistant covering 200 or an atmosphere composition in the vicinity of the heat resistant covering 200), and actuating the pump 360 when the monitored fire condition corresponds to a pre-determined fire condition.
In the embodiment shown, the method further comprises monitoring a heating condition of the fire spread-limiting assembly (such as a temperature of the heat resistant covering 200 or of the cooling fluid circulating within the flexible fluid lines 330), and modifying a flow rate of the pump 360 when the monitored heating condition corresponds to a pre-determined heating condition.
It is thus understood that the fire spread-limiting assembly 100 can be easily and quickly displaced and deployed so as to cover and/or to confine at least partially a fire.
Moreover, thanks to the cooling fluid circulating within the heat resistant covering 200, when the heat resistant covering 200 covers and/or confines at least partially the fire, the spreading of the fire can be limited.
It is further understood that the use of the complementary cooling fluid tank 400 allows providing additional cooling fluid to the cooling fluid circulation assembly 300, in case of a substantial vaporization of the cooling fluid circulating in the cooling fluid circulation assembly 300.
Moreover, it is understood that the heat resistant covering 200, the cooling fluid source 310 and the flexible fluid lines 330 have flexibility properties for them to be easily adapted to the shape and dimensions of the fire to be covered and/or confined at least partially. Fasteners (not represented) might further be mounted to the heat resistant covering 200 for the heat resistant covering 200 to be hung over the fire.
The fire spread-limiting assembly 100 of the disclosure is thus configured to form a mobile, extendible and flexible system configured to limit the spreading of a fire.
