Description

Title of the invention: Self-supporting autonomous fire protection structure

[0001] The present invention belongs to the technical field of preventing fires and protecting sensitive areas against fires of all kinds, in particular inside or in the outside vicinity of buildings, on construction sites, or near an area containing flammable vegetation.

[0002] The invention relates more particularly to an improved fire protection structure, intended to be installed on the ground at an area presenting a risk of fire. State of the art

[0003] The most widespread solution for fire protection in sensitive areas, and in particular the interior of buildings receiving people, consists of distributing fire extinguishers throughout the building. However, using a fire extinguisher can be difficult and requires human intervention. Standard fire extinguisher systems do not incorporate automatic detection of fire outbreaks. Finally, fire extinguishers are generally not easily transportable.

[0004] Mobile fire-fighting devices exist, for example a device with wheels described in the French patent application publication bearing the number FR 2 498 458 AL. This wheeled device also incorporates personal protective equipment such as gloves, goggles and a smoke mask. However, the device described in this document still requires activation by a person.

[0005] To overcome this major drawback, fire protection devices incorporating an automated triggering function have subsequently been proposed. These devices typically comprise a sprinkler powered, for example, by a pump, the sprinkler being started by an automated fire detector comprising a sensor. The sensor is, for example, a smoke detector or a temperature sensor. Such devices prepare and supplement the subsequent intervention of the firefighters, since they make it possible to initiate the extinction of the fire and to contain its spread, before the firefighters can intervene in the area and complete the extinction of the fire.

[0006] However, known autonomous fire protection devices are generally very bulky, not very compact and not transportable.

[0007] Furthermore, the deployment of these known devices is often difficult, especially that a connection to an external water reserve and / or to the urban water distribution network is generally necessary for the proper functioning of the pump and the sprinkler.

[0008] As a result, many isolated areas, particularly in the mountains, cannot currently be satisfactorily protected by existing autonomous fire-fighting systems. For the safety of people and the integrity of these areas, it is necessary to find fire protection systems that are more suited to the constraints of these areas.

[0009] Finally, existing fire protection devices generally have to be associated with external mechanical reinforcement elements for their support, which generates additional difficulties for the implementation of these devices.

[0010] Generally speaking, the ease of deployment and use, autonomy, modularity and effectiveness of current state-of-the-art fire protection devices can therefore be improved.

[0011] General description of the invention

[0012] In view of the above, known autonomous fire-fighting devices, aimed at automatically extinguishing emerging fires, or at least at limiting the spread of fires already declared before intervention by the fire brigade, must be improved to meet public safety issues.

[0013] In particular, there is a need for a fire protection device that is fully self-sufficient, that does not require external mechanical support, and that is able to operate where appropriate without connection to a public water distribution network or to an external tank.

[0014] Furthermore, it is preferable to seek an autonomous fire protection device which can cover a fairly wide perimeter, and which is in particular suitable for automatically extinguishing or containing a fire starting in all directions.

[0015] Furthermore, existing devices can be improved in terms of reducing floor space, in order to sufficiently protect cramped and isolated areas, or very dense areas in which saving space is crucial.

[0016] To meet these needs, the present invention relates, according to a first aspect, to a transportable fire-fighting structure configured to be installed on the ground of an area, intended to protect said area against fires, the structure comprising: a self-supporting frame mechanically supporting the structure, a fire extinguishing liquid reserve container configured to store a fire extinguishing liquid, a multidirectional sprinkler carried by the self-supporting frame, a booster fluidly connected to the liquid reserve container and fluidly connected to the multidirectional sprinkler, the booster further comprising connection means configured to allow connection of the booster with external piping, the booster being configured to supply a flow of fire extinguishing liquid at an extinguishing pressure to the multidirectional sprinkler or to said external piping, an electronic detection and control unit, configured to detect a position of a fire start or a fire at the area, the multidirectional sprinkler being configured so that its orientation is adjustable according to said fire start or fire position.

[0017] The fire-fighting structure according to the invention operates autonomously, allowing automatic detection and immediate limitation of fire outbreaks. No human presence is necessary to detect and contain fire outbreaks.

[0018] Such autonomy of the device is particularly useful in the case where the areas to be protected are isolated and difficult to access by firefighters and emergency services, which may be the case in areas located in medium or high mountains. The autonomous fire-fighting structure of the invention ensures that these isolated areas are protected in a reactive and effective manner.

[0019] An important additional advantage of the fire-fighting structure according to the invention is its very moderate size, particularly in terms of floor space occupied. Indeed, all the modules are preferably integrated within a single self-supporting frame, which may preferably be generally parallelepiped in shape. The extinguishing liquid reserve is autonomous and contained in the structure. In particular, in the case where the fire protection must be deployed inside or in the vicinity of a building, considerable space savings can be achieved by the protective structure of the invention.

[0020] An additional advantage is that the autonomous structure according to the invention is transportable and can therefore be easily moved as required, removed and / or replaced, or even redeployed from one site to another. In particular, the autonomous structure according to the invention can be transported to a workshop, in order to ensure maintenance and / or upkeep of the structure.

[0021] The fire protection structure of the invention is also intended to be self-sufficient, since it can operate where appropriate without any connection to the public water distribution network, and allows it to do without an electricity package and an HVAC package (this acronym being commonly used to designate the “Heating, Ventilation and Air Conditioning” function in the field of building ventilation equipment).

[0022] Optional and non-limiting features of the fire protection structure of the present invention may be the following, considered alone or in any technically possible combination of these features:

[0023] the self-supporting frame comprises a lower surface configured to rest on the ground, and comprises an upper surface extending parallel to the lower surface.

[0024] the frame comprises at least one post supporting the upper surface and resting on the lower surface, the liquid reserve container extending inside an internal volume delimited by said post, lower surface and upper surface.

[0025] the liquid reserve container occupies a volume greater than or equal to 30% of said internal volume provided by the self-supporting frame, preferably greater than or equal to 50% of said internal volume.

[0026] the self-supporting frame has a generally parallelepiped shape.

[0032] the electronic detection and control unit comprises at least one sensor among the following: a temperature variation sensor, and / or a smoke detector, and / or an infrared radiation sensor, and / or an ultraviolet radiation sensor, and / or an optical camera.

[0033] the electronic detection and control unit comprises a communication interface configured to transmit the electronic command for orientation of the multidirectional sprinkler remotely over a telecommunications network, preferably via the Internet and / or Ethernet and / or 3G and / or 4G and / or 5G and / or GSM voice.

[0034] the electronic detection and control unit comprises a communication interface configured to transmit an alarm signal to a remote operator, preferably via the Internet and / or Ethernet and / or 3G and / or 4G and / or 5G and / or GSM voice.

[0035] the booster comprises at least one pump and at least one motor, said motor being thermal or electric and being configured to actuate said pump.

[0036] the booster comprises two pumps mounted in parallel.

[0037] the booster is configured to provide, in operation, a flow of extinguishing liquid at a pressure of between 1 bar and 12 bars.

[0038] the fire-fighting structure comprises an autonomous power supply unit comprising an electric battery and / or comprising a fuel reserve, the engine being supplied with energy by said autonomous power supply unit.

[0039] the fire-fighting structure further comprises an electronic management module configured to generate a booster command, as a function of at least one parameter detected by the electronic detection and control unit.

[0040] the electronic detection and control unit is configured to transmit at regular intervals a periodic signal encoding at least one data item representative of an operating state of the structure, preferably via the Internet and / or Ethernet and / or 3G and / or 4G and / or 5G and / or GSM voice.

[0041] the fire-fighting structure further comprises rainwater collection means connected to the liquid reserve container.

[0042] According to a second aspect, the present invention relates to a fire protection system, configured to protect an area against fires autonomously, the system comprising a transportable fire-fighting structure as defined above, and further comprising a volume of fire-extinguishing liquid stored in the liquid reserve container integrated into said fire-fighting structure. The volume of fire-extinguishing liquid preferably comprises water mixed with an adjuvant liquid and / or water mixed with a retardant liquid.

[0043] General description of the figures

[0044] Other aims and advantages of the invention will emerge on reading the detailed description below, presented for illustrative and non-limiting purposes, said detailed description being supplemented by the following figures, among which:

[0045] [Fig. 1][Fig. 1] is a general schematic representation, in perspective, of a fire protection structure according to an exemplary embodiment of the invention. The fire protection structure is here positioned on the ground in an area to be protected.

[0046] [Fig.2][Fig.2] is an alternative view from the rear of the structure according to [Fig.l].

[0047] [Fig.3] [Fig.3] functionally represents an example of a booster circuit, which can be integrated into the fire protection structure according to Figures 1 and 2.

[0048] Detailed description of an exemplary embodiment of the invention

[0049] Figures 1 and 2 schematically illustrate an autonomous fire protection structure 1 according to an exemplary embodiment of the invention.

[0050] The protective structure 1 is configured to be positioned on a surface of an area to be protected, typically on a substantially flat ground 10 of the area. The protective structure 1 is typically deployed and maintained by professionals in the construction and building field, and / or by local authorities, although use by individuals is also envisaged.

[0051] The area to be protected is, for example, located inside or near a building, on a construction site, on a site containing flammable vegetation, etc.

[0052] The area to be protected is typically small, of the order of a few meters long and / or wide. Indeed, and as will be seen below, the dimensions and the autonomous and self-supporting nature of the protection structure 1 make it possible to envisage installing this structure on a reduced ground surface.

[0053] The protective structure 1 is advantageously self-supporting, that is to say that this structure 1 mechanically supports itself, in particular via its frame 2, without an external reinforcing or scaffolding element being necessary for the stability of the structure on the surface. Thus, in the present example, no external mechanical reinforcing element (such as a base, a beam, etc.) cooperates with the frame 2 of the structure 1.

[0054] The protective structure 1 further comprises here a container 3 for storing extinguishing liquid, a sprinkler 4, preferably multidirectional, a booster 5, a management module 6, an electronic detection and control unit 7, and an autonomous power supply unit 8. These different elements are described in detail below.

[0055] Self-supporting frame for supporting the fire-fighting structure

[0056] The self-supporting frame 2 providing mechanical support for the structure 1 is made of a material of high mechanical strength and rigidity, allowing the structure 1 to be supported and maintained. Preferably, the frame 2 is made of a metallic material. In the present example, the frame 2 is made of steel.

[0057] Importantly, the frame 2 is made of a material having very high fire resistance. Indeed, the frame 2 must, to a certain extent, resist the outbreak of fire.

[0058] For this purpose, preferably, the frame 2 is made of a material having a fire resistance of classification MO or Ml or M2, said classifications being established in accordance with the French standard NF P92-507 administered by AFNOR entitled “Fire safety - Building - Construction materials - Fire exits”. The French standard NF P92-507 defines a standardized classification of construction and furnishing materials according to their reaction to fire. Here, the fire resistance of the materials of the frame 2 is preferably of level M2.

[0059] Preferably, the frame 2 is designed so that all the functional modules of the fire-fighting device are integrated inside said frame 2. In particular, the reserve 3 of extinguishing liquid is contained in said frame 2.

[0060] Thus, a considerable saving of space can be achieved, which is particularly useful in the case where the fire protection must be deployed inside or in the vicinity of a building in which the deployment area may be small. In addition, the fire protection structure 1 is transportable and self-supporting. Said structure can therefore be moved, removed and / or replaced as required.

[0061] To this end, the self-supporting frame 2 here has a generally hollow parallelepiped shape, and defines a hollow internal volume in which the different modules can be placed.

[0062] Here, the frame 2 comprises a lower surface 20 configured to rest on the ground, an upper surface 21 extending parallel to the lower surface 20, and at least one post 22 supporting the upper surface 21 and resting on the lower surface 20. Preferably, the frame 2 comprises four posts 22 parallel to each other, at the corners of the upper and lower surfaces. The liquid reserve container 3 extends inside the volume delimited by said posts and the upper and lower surfaces.

[0063] As indicated above, the fire-fighting structure 1 is designed to achieve a reduced footprint and occupy limited ground space. The structure can thus equip isolated, cramped areas, including in the mountains, inside or near a building, etc.

[0064] The external volume occupied by the structure 1 is thus small, preferably less than 40 cubic meters, and the ground surface occupied by the structure 1 is reduced, preferably less than 20 square meters.

[0065] Preferably, the structure 1 has the following external dimensions: - an external length “L” between 2.0 meters and 8.0 meters (6.1 meters in this example); - an external width “1” between 1.0 meters and 4.0 meters (2.4 meters in this example); - finally, an external height “H” between 1.0 meters and 4.0 meters (2.6 meters in this example).

[0066] The lower surface 20 of the frame is here partly occupied by the liquid reserve 3. The remainder of the lower surface 20 forms a floor of the cabin on which one or more individuals can move.

[0067] The upper surface 21 can, for its part, optionally, accommodate several functional elements of the fire-fighting structure 1. In particular, as will be seen below, the multidirectional sprinkler 4 can be mounted on the upper surface 21.

[0068] In addition, an autonomous energy supply unit 8 can equip the structure 1. The supply unit 8 comprises, for example, one or more electric batteries. and / or a fuel reserve. The energy supply of the modules of the structure 1 is electrical and / or thermal. As will be seen below, the motorization necessary for the operation of the modules of the structure 1 can be directly supplied with energy by such an autonomous power supply unit 8. An advantage is that it can, if necessary, avoid the need for a connection to the public electricity distribution network.

[0069] Here, the fire-fighting structure 1 is equipped with substantially flat photovoltaic cells, placed above the upper surface 21. Alternatively or in combination, a wind system and / or a fuel reserve can equip the structure 1.

[0070] Fire extinguishing liquid reserve

[0071] As illustrated in Figures 1 and 2, the liquid reservoir 3 is preferably of parallelepipedal general shape, even if other geometries can be envisaged. The reservoir 3 comprises for example water, optionally and advantageously mixed with a retardant liquid and / or an adjuvant liquid. The contents of the reservoir 3 thus constitute a fire extinguishing liquid dispersible at the outlet of the sprinkler 4 and / or at the outlet of an external pipe.

[0072] In the present example, a rear wall 12 extends vertically from the lower surface 20 to the upper surface 21. The liquid reserve 3 is preferably placed against the rear wall 12. The reserve 3 preferably occupies a volume greater than or equal to 30% and less than or equal to 70% of the internal volume provided by the frame 2, preferably greater than or equal to 50% and less than or equal to 70% of said internal volume.

[0073] The internal space of the frame 2 not occupied by the reserve 3 forms a cabin, in which a person can stand. A door 13 is optionally made in the rear wall 12, allowing access to the cabin by a person.

[0074] In the present example, the sides of the frame 2 different from the rear side remain open, and do not have a closing wall.

[0075] A useful volume of the reserve 3 is for example greater than or equal to 10 cubic meters and less than or equal to 30 cubic meters. The useful volume of the tank is here equal to approximately 18 cubic meters. A large volume of fire extinguishing liquid, sufficient to at least temporarily contain the outbreak of a fire, can therefore be stored there, while ensuring moderate space requirements.

[0076] Thanks to the reserve 3 of extinguishing liquid, the fire-fighting structure 1 can operate autonomously if necessary, without connection to any public water distribution network or to any external source of liquid. The reserve 3 of liquid supplies the multidirectional sprinkler 4 and the booster 5 with a flow of fire-fighting liquid, in the event of a fire being detected in the vicinity of the structure. The fire-fighting structure 1 according to the invention is thus intended to be self-sufficient.

[0077] It is further advantageous to provide for rainwater recovery, to supply the reserve 3. To this end, in the present example, the upper surface 21 of the frame 2 comprises collection means 11, fluidically connected to the reserve 3.

[0078] Booster; Multidirectional sprinkler

[0079] The autonomous fire extinguishing means embedded in the fire-fighting structure 1 are here mainly constituted by a sprinkler 4, capable of projecting a flow of extinguishing liquid in all directions. To do this, the sprinkler 4 is preferably movable in rotation at 360° relative to the frame 2, around a substantially vertical axis.

[0080] The multidirectional sprinkler 4 is, in the present example, mounted on an outer side of the self-supporting frame 2. The sprinkler 4 is preferably located on the upper surface 21 of the frame 2, here along an edge of the upper surface 21.

[0081] The sprinkler 4 is electronically controllable. Here, the sprinkler 4 is in particular configured to receive an angular orientation command transmitted by a communication interface, said sprinkler orientation command being generated preferentially by the electronic control detection unit 7 or by a separate module communicating with said detection unit 7.

[0082] A booster 5 is embedded in the fire-fighting structure 1. The booster 5 is configured to be triggered automatically in the event of detection of the start of a fire by the detection unit. Then drawing from the reserve 3, the booster 5 can produce, from the extinguishing liquid stored in this reserve, an extinguishing flow rate and pressure suitable for supplying the sprinkler 4. The booster 5 is fluidically connected on the one hand to the reserve 3, and on the other hand to the multidirectional sprinkler 4.

[0083] Advantageously, the booster 5 may further comprise connection means 59 configured to allow connection of the booster 5 to an external pipe. Thus, if necessary, the flow of extinguishing liquid supplied by the multidirectional sprinkler 4 may be supplemented, or replaced, by a flow of extinguishing liquid at the outlet of the external pipe.

[0084] The booster 5 is preferably configured to supply, in operation, a flow of extinguishing liquid at an extinguishing pressure of between 1 bar and 12 bars, for example to the sprinkler 4 and / or to the aforementioned external piping.

[0085] In the present example, the booster 5 is directly positioned next to a wall of the container forming the reserve 3, on the cabin side.

[0086] [Fig. 3] attached shows functionally a circuit of the booster 5, according to a non-limiting example of embodiment.

[0087] The booster 5 comprises at least one pump 52 capable of providing a flow of liquid at a flow rate and extinguishing pressure sufficient to supply the sprinkler 4. The fire-fighting structure 1 comprises a thermal or electric motor configured to operate said pump.

[0088] The booster 5 preferably further incorporates a control cabinet. As will be detailed below, the booster 5 can receive a command from an electronic management module, depending on the signals transmitted by the fire detection unit.

[0089] The booster 5 according to the present example is preferably supplied with three-phase current of voltage 400 volts.

[0090] In the present example, the booster 5 comprises two pumps 52 mounted in parallel, capable of setting in motion a flow of extinguishing liquid between an inlet 530 (suction manifold) and an outlet 531 (discharge pipe).

[0091] Preferably, the pumps 52 are associated with non-return valves and isolation valves in order to ensure control of the extinguishing flow rate. Here, each pump 52 is associated with a non-return valve 54, and is associated with a pair of isolation valves 55 making it possible to selectively isolate each pump 52.

[0092] The booster 5 is preferably further equipped with a series of sensors, making it possible to control the proper functioning of the booster 5 and to monitor the operating state of the structure. In the present example, the booster 5 comprises a first pressure sensor 56 (preferably a 0-16 bar pressure gauge) at the suction inlet, and / or a second pressure sensor 56 (preferably a 0-16 bar pressure gauge) at the discharge outlet. The booster 5 here further comprises a pressure switch 58.

[0093] In addition, the booster 5 is optionally equipped with a water shortage sensor 57.

[0094] Electronic fire detection unit; Electronic management module

[0095] Advantageously, the fire-fighting structure 1 operates autonomously with automatic detection of fire outbreaks within the protection perimeter of the structure. No human presence is necessary for fire detection.

[0096] The detection and monitoring of the protection perimeter of the structure are ensured by an electronic detection and control unit 7, comprising one or more sensors preferably placed outside the module. These sensors are capable of scanning a predetermined perimeter around the fire-fighting structure 1.

[0097] Preferably, the electronic unit 7 comprises at least one sensor and preferably several sensors chosen from the following group: a temperature variation sensor, and / or an infrared radiation sensor, and / or a smoke detector, and / or an ultraviolet radiation sensor, and / or an optical camera.

[0098] Thus, the electronic unit 7 is capable of autonomously and reactively detecting the start of a fire within the perimeter by reacting to a rise in temperature in surface and / or the appearance of infrared radiation and / or the appearance of ultraviolet radiation. Such detection prepares the way for subsequent intervention by firefighters, since it allows the extinction of the fire to be initiated and its spread to be contained. Here again, fire-fighting structure 1 is intended to be self-sufficient.

[0099] In the present example, the electronic unit 7 comprises a surface temperature sensor (not illustrated in the attached figures) and / or a camera 70. The camera 70 here comprises an optical camera placed on the upper surface 21 of the self-supporting frame 2. Alternatively or in combination, the camera 70 can enable detection of infrared radiation and / or detection of ultraviolet radiation in the protection perimeter.

[0100] Preferably and advantageously, the electronic detection unit 7 is also configured to receive an orientation command for the multidirectional sprinkler 4 as a function of at least one parameter detected by the electronic detection unit 7.

[0101] Here, the orientation of the multidirectional sprinkler 4 is automatically adjusted according to the detected position of the start of the fire or fire. The detected position is for example recorded in an electronic memory of the structure, for example in the form of ground coordinates.

[0102] An angular displacement command of the sprinkler 4 is then processed by calculation means of the electronic unit 7 as a function of said detected position, so as to move for example the aiming axis of the sprinkler 4 so that it disperses the extinguishing liquid at the level of the fire start.

[0103] Preferably and advantageously, the electronic unit 7 is associated with an electronic management module 6 ensuring the control of the booster 5.

[0104] The booster 5 receives an electronic command from the electronic management module 6 as a function of the measurements transmitted by the electronic unit 7. The command of the booster 5 comprises, for example, an extinguishing flow rate setpoint and / or an extinguishing pressure setpoint to be supplied at the inlet of the multidirectional sprinkler 4, and / or at the inlet of an external pipe connected to the booster 5 via the connection means 59. The command of the booster 5 is, for example, determined by calculation means of the electronic management module 6.

[0105] The electronic management module 6 is for example integrated into a control cabinet of the booster 5.

[0106] Preferably, the structure 1 comprises a telecommunications interface, configured to transmit an electronic command for orientation of the sprinkler 4 remotely over a telecommunications network, preferably via the Internet and / or Ethernet and / or 3G and / or 4G and / or 5G and / or GSM voice. The electronic command for orientation of the sprinkler can then be received and processed by the electronic unit 7. Alternatively, the sprinkler orientation command can be generated directly at the electronic unit 7 or transmitted by wire to the electronic unit 7.

[0107] Furthermore, a periodic signal encoding at least one data item representative of an operating state of the structure can be generated and transmitted periodically over a remote network, preferably via the Internet and / or Ethernet and / or 3G and / or 4G and / or 5G and / or GSM voice. The periodic signal can pass through the telecommunications interface.

[0108] Alternatively or in combination, an alarm signal representative of the location and / or intensity of a fire outbreak within the protection perimeter of the structure can be generated and transmitted periodically over a remote network, for example via the telecommunications interface.

[0109] Such a telecommunications interface is for example integrated into the electronic management module 6.

[0110] Thus, in the event of detection of a fire starting and in the event of the booster being triggered, the fire-fighting structure automatically alerts a remote electronic unit, belonging for example to fire protection services: fire brigade and / or civil security and / or local authorities, etc.

[0111] The alarm transmitted to the fire protection services can specify the location and / or intensity of a fire outbreak and / or specify the type of fire outbreak. Such an alarm prepares and completes the subsequent intervention of the fire brigade to extinguish the fire detected in the area.

[0112] The autonomous fire-fighting structure of the invention thus ensures that isolated areas that are difficult for firefighters to access are protected in a reactive and effective manner.
