Description

Technical field

[0001] The invention relates to the field of firefighting. In particular, it relates to a mobile fire water reserve and its associated installation method.

[0002] Similar devices are known from GB2461934A and AU2007101010A4. Prior art

[0003] Firefighting requires the presence of numerous firefighting water reserves throughout an area. This ensures that in the event of a fire, firefighters have the necessary volume of water available. This volume must be accessible to firefighters at all times and positioned in a single location to avoid requiring additional maneuvers for firefighting teams.

[0004] We know about flexible fire reserves that are generally found in isolated areas or in sectors where the water network is insufficient. This fire defense solution can also be used in urban and industrial areas such as during the creation of commercial spaces or residential areas, from the extension of a factory to the rapid upgrading of an agricultural or industrial building. In addition, flexible tanks are also known to act as relay storage during a forest fire defense intervention.

[0005] However, flexible fire reserves require a very large land footprint for installation on the ground.

[0006] In fact, for a water volume of 30 m 3< , a flexible fire reserve requires a ground installation footprint of approximately 50 m 2< with a direct outlet and approximately 65 m 2< with a remote outlet.

[0007] However, it is not always possible to have so much land, for example in forests or mountains.

[0008] Furthermore, installing a flexible fire reserve is complex, particularly because handling it with handling equipment is prohibited to avoid damaging it. Therefore, many tedious tasks must be carried out manually when installing a flexible fire reserve, such as stirring it and shaking it while avoiding creases.

[0009] There is therefore a need for a fire reserve that is easily installed and that can be placed in areas where the land area for ground installation is limited. Summary of the invention

[0014] Furthermore, each of the plurality of first vertical beams is fixed to the maritime container by irremovable fixing means so as to arrange the first vertical beams two by two facing each other, on either side of the internal faces of the side walls.

[0015] Furthermore, every second cross beam is attached to the main part of the endoskeleton by the removable attachment means.

[0016] In a first implementation of the first embodiment, the main portion of the endoskeleton further comprises a plurality of third vertical beams.

[0027] The figures do not necessarily respect the scales, particularly in thickness, and this is for illustration purposes. Description of the embodiments

[0028] One of the objectives of this invention is to considerably reduce the land footprint of ground-based fire reserves.

[0029] To achieve this, the inventors propose a fire water reserve that is formed in a maritime container.

[0030] In fact, the footprint of a standard maritime container is around 15 m 2 for an available volume of 33 m 3, while the footprint of a flexible fire reserve is around 50 m 2 with a direct connection and around 65 m 2 with a remote connection, for a water volume of 30 m 3.

[0031] Furthermore, the installation of a fire water reserve according to the invention can be carried out with handling equipment which reduces the installation time.

[0032] Thus, the invention relates to a mobile fire water reserve as functionally illustrated in the Figure 1 .

[0033] In the Figure 1 , the fire water reserve 100 comprises a maritime container 110, an endoskeleton 120 and a flexible membrane 130.

[0034] In practice, the maritime container 110 is functionally coupled to the endoskeleton 120 and the endoskeleton 120 is functionally coupled to the flexible membrane 130.

[0035] By functional coupling is meant that the maritime container 110 and the endoskeleton 120 are connected, for example mechanically, and also the endoskeleton 120 and the flexible membrane 130.

[0036] There Figure 2 illustrates the 110 shipping container.

[0037] In the invention, the maritime container 110 is of a type known per se, such as an ISO standardized maritime container for general use (also called a “dry” container), for example according to the NF ISO 668 standard.

[0038] In the example of the Figure 2 , the maritime container 110 has a front wall 111, a rear wall 112, a top wall 113, a bottom wall 114 and side walls 115.

[0039] Typically, the front wall 111 comprises at least one access door 111a to the interior of the maritime container 110.

[0040] Furthermore, in the invention, the external face of the lower wall 114 is intended to rest on the ground.

[0041] Thus, the fire water reserve 100 is mobile and can be moved from one place to another by a lifting device such as a crane.

[0042] There Figure 3 illustrates the endoskeleton 120.

[0043] In the invention, the endoskeleton 120 is arranged inside the shipping container 110. Furthermore, the endoskeleton 120 is designed to reinforce the shipping container 110 from the inside.

[0044] In a first example, the endoskeleton 120 is made of metal.

[0045] In a second example, the endoskeleton 120 is made of composite material. Optionally, the composite material may be reinforced with fibers to locally stiffen the endoskeleton 120.

[0046] However, the endoskeleton 120 may be formed from other materials without requiring substantial modifications to the invention.

[0047] In the invention, the flexible membrane 130 is designed to be hooked inside the maritime container 110 so as to move from an initial position to a hooking position.

[0048] In the initial position, the flexible membrane 130 is substantially unfolded flat.

[0049] In the hanging position, the flexible membrane 130 is substantially folded to take the shape of a hanging pocket which has an upper opening towards the upper wall 113 so as to form a reservoir for storing water.

[0050] Therefore, in the hanging position, the water only comes into contact with the inner wall of the tank thus formed.

[0051] Furthermore, the flexible membrane 130 is waterproof. Thus, the attachment position of the flexible membrane 130 prevents any risk of water leaking out of the tank, except through the upper opening.

[0052] In a first example, the flexible membrane 130 is made of Polyvinyl chloride (PVC).

[0053] In a second example, the flexible membrane 130 is made of Ethylene Propylene Diene Monomer (EPDM).

[0054] However, the flexible membrane 130 may be formed from other materials without requiring substantial modifications of the invention.

[0055] Back to the Figure 1 , the endoskeleton 120 comprises a main part 121 and a removable part 122.

[0056] In practice, the removable part 122 of the endoskeleton 120 is fixed to the main part 121 of the endoskeleton 120 by removable fixing means.

[0057] “Removable fixing means” means fixing means which allow reversible fastening to be achieved.

[0058] In a first example, the removable fixing means are known fixing means by bolting bolt / nut assemblies.

[0059] In a second example, the removable fixing means are known screw fixing means.

[0060] However, other suitable removable fastening means may be used without requiring substantial modifications to the invention.

[0061] Furthermore, when the flexible membrane 130 is in the hooked position, the removable part 122 of the endoskeleton 120 is arranged inside the tank and is configured to absorb all or part of the forces exerted by the pressure of the water on the internal faces of the side walls 115.

[0062] Furthermore, in the invention, the flexible membrane 130 comprises a plurality of connection holes 131 which are configured to allow the passage of all or part of the removable fixing means through it, when the flexible membrane 130 is in the hooking position.

[0063] In one way of producing the flexible membrane 130, the connection holes 131 are formed by stitching into the flexible membrane 130.

[0064] In a particular way of implementing the invention, the removable fixing means are configured to pass in a sealed manner through the connection holes 131 of the flexible membrane 130.

[0065] In one example, sealing is achieved by at least one O-ring which is inserted between the removable fixing means and the flexible membrane 130.

[0066] In one way of making the endoskeleton 120, as illustrated in the Figure 3 , the main part 121 of the endoskeleton 120 comprises a plurality of first vertical beams 121a and the removable part 122 of the endoskeleton 120 comprises at least one second transverse beam 122a.

[0067] In this way of producing the endoskeleton 120, each of the plurality of first vertical beams 121a is fixed to the maritime container 110 by irremovable fixing means so as to arrange the first vertical beams 121a two by two facing each other, on either side of the internal faces of the side walls 115.

[0068] “Immovable fixing means” means fixing means which enable irreversible attachment to be achieved.

[0069] In a first example, the irremovable fixing means are known fixing means by welding.

[0070] In a second example, the irremovable fixing means are known fixing means by gluing.

[0071] However, other suitable non-removable fixing means may be used without requiring substantial modifications to the invention.

[0072] There Figure 4 illustrates a side wall 115 on which a first vertical beam 121a has been fixed. Thus, as can be seen in the Figure 4 , the side walls 115 have a trapezoidal section so that the first vertical beams 121a can be fixed in the space which separates two adjacent trapezoids, at the level of the large bases of the trapezoidal section.

[0073] In a particular embodiment of how to make the endoskeleton 120, each of the plurality of first vertical beams 121a extends toward the inner face of the bottom wall 114 and toward the inner face of the top wall 113.

[0074] In a first example, all or part of the plurality of first vertical beams 121a comes into contact, at one of its ends, with the internal face of the upper wall 113.

[0075] In a second example, all or part of the plurality of first vertical beams 121a comes into contact, at one of its ends, with the internal face of the lower wall 114.

[0076] In a third example, all or part of the plurality of first vertical beams 121a comes into contact, respectively, at one of their ends, with the internal face of the upper wall 113 and the internal face of the lower wall 114.

[0077] Still in this way of producing the endoskeleton 120, each second transverse beam 122a is fixed to the main part 121 of the endoskeleton 120 by the removable fixing means.

[0078] In a particular embodiment of the way of producing the endoskeleton 120, each second transverse beam 122a extends between two first vertical beams 121a which are opposite each other.

[0079] Furthermore, in the manner of making the endoskeleton 120, the main part 121 of the endoskeleton 120 further comprises a plurality of third vertical beams 121b.

[0080] In this case, each of the plurality of third vertical beams 121b is fixed to the internal faces of the rear wall 112 by irremovable fixing means.

[0081] Further, in a particular embodiment of how to make the endoskeleton 120, each of the plurality of third vertical beams 121b extends toward the inner face of the bottom wall 114 and toward the inner face of the top wall 113.

[0082] In a first example, all or part of the plurality of third vertical beams 121b comes into contact, at one of its ends, with the internal face of the upper wall 113.

[0083] In a second example, all or part of the plurality of third vertical beams 121b comes into contact, at one of its ends, with the internal face of the lower wall 114.

[0084] In a third example, all or part of the plurality of third vertical beams 121b comes into contact, respectively, at one of their ends, with the internal face of the upper wall 113 and the internal face of the lower wall 114.

[0085] Furthermore, in the manner of producing the endoskeleton 120, the main part 121 of the endoskeleton 120 further comprises at least a fourth horizontal beam 121c.

[0086] In particular, the fourth horizontal beam 121c is fixed to the first vertical beams 121a and to the third vertical beams 121b by irremovable fixing means, so as to connect the first vertical beams 121a and the third vertical beams 121b together, without being in direct contact with the internal walls of the maritime container 110.

[0087] Furthermore, in the invention, each second transverse beam 122a is fixed to the fourth horizontal beam 121c by the removable fixing means.

[0088] In a particular way of implementing the invention, the fourth horizontal beam 121c and the second transverse beam 122a are arranged substantially halfway up the maritime container 110.

[0089] Indeed, the inventors have noted that it is at this height that the water pressure on the internal faces of the side walls 115 is maximum.

[0090] In a second way of making the endoskeleton 120, the main part 121 of the endoskeleton 120 further comprises a plurality of fifth horizontal beams 121d and at least one sixth vertical beam 121e.

[0091] In practice, the plurality of fifth horizontal beams 121d and at least one sixth vertical beam 121e are fixed to the internal face of the front wall 111 by irremovable fixing means, so as to reinforce the access door 111a.

[0092] In a particular way of implementing the invention, the fire water reserve 100 further comprises a plurality of hooking elements 123, for example hooking hooks, which are fixed in the upper part of the fire water reserve 100.

[0093] In a first example, the plurality of attachment elements 123 are fixed to the upper part of the internal faces of the front, rear and side walls 111, 112, 115 of the maritime container 110 by irremovable fixing means.

[0094] In a second example, the plurality of attachment elements 123 are fixed to the internal face of the upper wall 113 of the maritime container 110 by irremovable fixing means.

[0095] In a third example, the plurality of attachment elements 123 are fixed to the endoskeleton 120, for example to a rod element of the endoskeleton 120 which goes all the way around the inside of the maritime container 110.

[0096] Furthermore, the flexible membrane 130 further comprises a plurality of anchoring elements 132, for example hanging eyelets, which are configured to be hung by the plurality of hanging elements 123.

[0097] In one embodiment of the invention, the fire water reserve 100 further comprises a suction line 140 and a filling line 150.

[0098] The suction line 140 and the filling line 150 respectively define a sealed passage through at least one of the walls 111, 112, 113, 114, 115 of the maritime container 110, between the flexible membrane 130 and the exterior of the maritime container 110.

[0099] In one example, the sealing is achieved by at least one sealing flange and at least one sealing counter-flange which are assembled so as to compress the flexible membrane 130 on either side.

[0100] The suction line 140 is intended to bring water out of the flexible membrane 130 to a device external to the maritime container 110. In particular, the device is adapted to consume water.

[0101] The filling line 150 is intended to bring water into the flexible membrane 130 from a supply source external to the maritime container 110. In particular, the supply source is adapted to deliver water.

[0102] The invention also relates to a method of installing 200 the fire water reserve 100 as illustrated in the Figure 5 .

[0103] The method 200 firstly comprises a step 210 of supplying a fire water reserve 100 as described above.

[0104] The method 200 then comprises a step 220 of opening the access door 111a of the front wall 111.

[0105] In fact, the method according to the invention makes it possible to carry out the installation with the access doors 111a open, until the installation is finalized and delivered to the site.

[0106] Then, the method 200 comprises a step 230 of removing the removable part 122 of the endoskeleton 120.

[0107] The removal of the removable part 122 of the endoskeleton 120 makes it possible not to be hindered when installing the flexible membrane 130 inside the maritime container 110.

[0108] Then, the method 200 comprises a step 240 of attaching the plurality of anchoring elements 132 of the flexible membrane 130 to the plurality of attachment elements 123 of the main part 121 of the endoskeleton 120.

[0109] In practice, only the anchoring elements 132 of the flexible membrane 130 are attached, which are associated with the plurality of attachment elements 123 of the main part 121 of the endoskeleton 120 which are located at the level of the internal faces of the rear wall 112 and the side walls 115. In this way, the flexible membrane 130 does not obstruct the access door 111a which is left free of access.

[0110] Subsequently, the method 200 comprises a step 250 of replacing the removable part 122 of the endoskeleton 120 on the main part 121 of the endoskeleton 120, so that the removable fixing means pass in a sealed manner through the connection holes 131 of the flexible membrane 130.

[0111] Then, the method 200 comprises a step 260 of placing the suction pipe 140 and the filling pipe 150, so as to define respectively, a sealed passage through at least one of the walls 111, 112, 113, 114, 115 of the maritime container 110, between the flexible membrane 130 and the exterior of the maritime container 110.

[0112] Then, the method 200 comprises a step of closing and sealing 270, from the outside, the access door 111a of the front wall 111.

[0113] In practice, before closing and sealing, the anchoring elements 132 of the flexible membrane 130 are attached, which are associated with the plurality of attachment elements 123 of the main part 121 of the endoskeleton 120 which are located at the level of the internal face of the front wall 111.

[0114] Furthermore, the access door 111a of the front wall 111 is closed by irremovable closing means, for example by welding.

[0115] Finally, the method 200 comprises a step 280 of connecting the filling pipe 150 to a power source external to the maritime container 110 and which is adapted to deliver water.

[0116] We have described and illustrated the invention. However, the invention is not limited to the embodiments we have presented. Thus, an expert in the field can deduce other variants and embodiments from reading the description and the attached figures.

[0117] The invention may be the subject of numerous variants and applications other than those described above within the scope of the appended claims. In particular, unless otherwise indicated, the different structural and functional characteristics of each of the implementations described above should not be considered as combined and / or closely and / or inextricably linked to each other, but on the contrary as simple juxtapositions. Furthermore, the structural and / or functional characteristics of the different embodiments described above may be the subject in whole or in part of any different juxtaposition or any different combination.

[0118] For example, depending on the needs, the flexible membrane 130 may comprise the plurality of attachment elements 123 while the fire water reserve 100 may comprise the plurality of anchoring elements 132.

[0119] Finally, depending on requirements, the access door 111a of the front wall 111 can be closed by removable closing means.
