Description

MOBILE FIRE WATER TANK AND ASSOCIATED INSTALLATION METHOD

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

Fighting fires requires the presence of numerous fire water reserves throughout a territory. Thus, in the event of a fire, the firefighters are assured of having the necessary volume of water available. This volume must be accessible at all times by the firefighters and positioned in a single place, so as not to generate additional maneuvers for the fire response teams.

We know the flexible fire reserves that are generally encountered in isolated areas or in sectors where the water network is insufficient. This fire protection solution can also be used in urban and industrial areas such as when creating commercial areas 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 an intervention to defend forests against fire.

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

In fact, for a volume of water of 30 m ³ , a flexible fire reserve requires a footprint for installation on the ground of around 50 m ² with a direct outlet and around 65 m ² with a remote outlet.

However, it is not always possible to have as much land, for example in the forest or in the mountains.

In addition, the installation of a flexible fire reserve is complex, in particular because handling it using handling equipment is prohibited so as not to damage it. Thus, many tedious tasks must be carried out manually when installing a flexible fire reserve, such as stirring it, shaking it while avoiding creases.

There is therefore a need for a fire reserve which is easily installable and which can be placed in areas where the land area for installation on the ground is limited.

The invention aims to solve, at least partially, this need.

The invention relates in particular to a mobile fire water reserve which comprises:
- a maritime container which has a front wall, a rear wall, an upper wall, a lower wall and side walls, the outer face of the lower wall being intended to rest on the ground,
- an endoskeleton which is disposed inside the sea container and which is designed to reinforce the sea container from the inside, and
- a flexible waterproof membrane which is designed to be hooked inside the maritime container so as to pass from an initial position to a hooking position in which the flexible membrane takes the form of a hanging pocket which presents an upper opening in the direction of the upper wall, and which is intended to form a reservoir for storing water.

Otherwise,
- the endoskeleton comprises a main part and a removable part, the removable part of the endoskeleton being fixed to the main part of the endoskeleton by removable fixing means, and, when the flexible membrane is in the hooking position , the removable part of the endoskeleton 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, and
- the flexible membrane comprises a plurality of connection holes which are configured to allow the passage of all or part of the removable fixing means through it, when the flexible membrane is in the hooking position.

In a first embodiment, the main part of the endoskeleton comprises a plurality of first vertical beams, and
- the removable part of the endoskeleton comprises at least a second transverse beam.

Furthermore, each of the plurality of first vertical beams is fixed to the shipping container by non-removable fastening means so as to arrange the first vertical beams facing each other in pairs, on either side of the internal faces of the side walls.

Furthermore, each second transverse beam is fixed to the main part of the endoskeleton by the removable fixing means.

In a first implementation of the first embodiment, the main part of the endoskeleton further comprises a plurality of third vertical beams.

Furthermore, each of the plurality of third vertical beams is fixed on the internal faces of the rear wall by non-removable fixing means

In a second implementation of the first embodiment, the main part of the endoskeleton further comprises at least a fourth horizontal beam, which is fixed to the first vertical beams and to the third vertical beams by non-removable fixing means, so as to link together the first vertical beams and the third vertical beams, without being in direct contact with the internal walls of the maritime container.

Furthermore, each second transverse beam is fixed to the fourth horizontal beam by the removable fixing means

In a third implementation of the first embodiment, the fourth horizontal beam and the second transverse beam are arranged substantially at mid-height of the shipping container

In a second embodiment, the front wall comprises at least one access door to the interior of the shipping container, the main part of the endoskeleton further comprises a plurality of fifth horizontal beams and at least one sixth beam vertical, which are fixed to the internal face of the front wall by non-removable fixing means

the flexible membrane further comprises a plurality of anchoring elements, for example hooking eyelets, which are configured to be hooked by the plurality of hooking elements.

In a fourth embodiment, the removable fixing means are configured to pass through the connection holes of the flexible membrane in a sealed manner.

In a fifth embodiment, the fire water reserve further comprises a suction pipe and a filling pipe which respectively define a sealed passage through at least one of the walls of the maritime container, between the flexible membrane and the exterior of the maritime container, the suction pipe being intended to bring water out of the flexible membrane to a device external to the maritime container and which is suitable for consuming water, the filling pipe being intended to bring water into the flexible membrane from a supply source external to the shipping container and which is adapted to deliver water.

The invention also relates to a method for installing a mobile fire water tank, the method comprising:
- a step of supplying a mobile fire water tank according to the invention,
- a step for opening the access door to the front wall,

The figures do not necessarily respect the scales, in particular in thickness, and this for purposes of illustration.

One of the objectives of this invention is to considerably reduce the land footprint for ground installation of fire reserves.

For this, the inventors propose a reserve of fire water which is formed in a shipping container.

Indeed, the footprint of a standard shipping 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 intake and around 65 m ² with a remote intake, for a volume of water of 30 m ³ .

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

Thus, the invention relates to a mobile fire water tank as functionally illustrated in the .

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

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.

By functional coupling, it is meant that the maritime container 110 and the endoskeleton 120 are linked, for example mechanically, and also the endoskeleton 120 and the flexible membrane 130.

The illustrates shipping container 110.

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.

In the example of the , the sea container 110 has a front wall 111, a rear wall 112, a top wall 113, a bottom wall 114 and side walls 115.

Conventionally, the front wall 111 comprises at least one access door 111a inside the maritime container 110.

Furthermore, in the invention, the outer face of the lower wall 114 is intended to rest on the ground.

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

The illustrates endoskeleton 120.

In the invention, the endoskeleton 120 is placed inside the shipping container 110. Furthermore, the endoskeleton 120 is designed to reinforce the shipping container 110 from the inside.

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

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

However, the endoskeleton 120 can be formed from other materials without requiring substantial modifications of the invention.

In the invention, the flexible membrane 130 is designed to be hooked inside the shipping container 110 so as to pass from an initial position to a hooking position.

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

In the hooking position, the flexible membrane 130 is substantially folded to take the form of a suspended pocket which has an upper opening in the direction of the upper wall 113 so as to form a reservoir for storing water.

Therefore, in the hooking position, the water only comes into contact with the inner wall of the tank thus formed.

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.

In a first example, the flexible membrane 130 is made of polyvinyl chloride (PVC).

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

However, the flexible membrane 130 can be formed from other materials without requiring substantial modifications of the invention.

Back to the , the endoskeleton 120 comprises a main part 121 and a removable part 122.

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.

The term "removable fastening means" means fastening means which allow reversible fastening to be achieved.

In a first example, the removable fastening means are known fastening means by bolting bolt/nut assemblies.

In a second example, the removable fastening means are known fastening means by screwing.

However, other suitable removable fastening means may be used, without requiring substantial modifications of the invention.

Furthermore, when the flexible membrane 130 is in the attachment position, the removable part 122 of the endoskeleton 120 is placed inside the reservoir and is configured to absorb all or part of the forces exerted by the pressure of the water on the inner faces of the side walls 115.

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 fastening means through it, when the flexible membrane 130 is in the hooking position.

In one way of making the flexible membrane 130, the connecting holes 131 are formed by stitching in the flexible membrane 130.

In a particular way of carrying out the invention, the removable fastening means are configured to pass through the connection holes 131 of the flexible membrane 130 in a sealed manner.

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

In one way of making the endoskeleton 120, as illustrated in the , 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.

In this way of making the endoskeleton 120, each of the plurality of first vertical beams 121a is fixed to the maritime container 110 by non-removable fastening means so as to arrange the first vertical beams 121a facing each other in pairs, on either side. other side of the inner faces of the side walls 115.

The term "irremovable fastening means" means fastening means which make it possible to achieve irreversible fastening.

In a first example, the non-removable fixing means are known fixing means by welding.

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

However, other appropriate non-removable fastening means may be used, without requiring substantial modifications to the invention.

The illustrates a side wall 115 to which a first vertical beam 121a has been fixed. Thus, as can be seen in the , 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.

In a particular embodiment of how endoskeleton 120 is made, each of the plurality of first vertical beams 121a extends toward the inside face of bottom wall 114 and toward the inside face of top wall 113.

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.

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.

In a third example, all or part of the plurality of first vertical beams 121a come 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 .

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

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

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

In this case, each of the plurality of third vertical beams 121b is fixed to the internal faces of the rear wall 112 by non-removable fixing means.

Further, in a particular embodiment of how endoskeleton 120 is made, each of the plurality of third vertical beams 121b extends toward the inside face of bottom wall 114 and toward the inside face of top wall 113.

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.

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.

In a third example, all or part of the plurality of third vertical beams 121b come 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 .

Moreover, in the way of making the endoskeleton 120, the main part 121 of the endoskeleton 120 further comprises at least a fourth horizontal beam 121c.

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 link the first vertical beams 121a and the third vertical beams 121b together, without being in contact directly with the internal walls of the maritime container 110.

In addition, in the invention, each second transverse beam 122a is fixed to the fourth horizontal beam 121c by the removable fixing means.

In a particular way of carrying out the invention, the fourth horizontal beam 121c and the second transverse beam 122a are arranged substantially at mid-height of the maritime container 110.

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

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.

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 non-removable fixing means, so as to reinforce the access door 111a.

In a particular way of carrying out the invention, the fire water reserve 100 further comprises a plurality of attachment elements 123, for example attachment hooks, which are fixed in the upper part of the reserve of fire water 100.

In a first example, the plurality of attachment elements 123 are fixed on the upper part of the internal faces of the front, rear and

side walls

111, 112, 115 of the maritime container 110 by irremovable fastening means.

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.

In a third example, the plurality of attachment elements 123 are fixed on the endoskeleton 120, for example on a rod element of the endoskeleton 120 which runs all the way inside the maritime container 110.

Furthermore, the flexible membrane 130 further comprises a plurality of anchoring elements 132, for example hooking eyelets, which are configured to be hooked by the plurality of hooking elements 123.

In one way of carrying out the invention, the fire water reserve 100 further comprises a suction pipe 140 and a filling pipe 150.

The suction pipe 140 and the filling pipe 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 sea container 110.

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

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

The filling line 150 is intended to bring water into the flexible membrane 130 from a power source external to the shipping container 110. In particular, the power source is adapted to deliver water.

The invention also relates to a method 200 for installing the fire water reserve 100 as illustrated in the .

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

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

Indeed, the method according to the invention makes it possible to carry out the installation with the access doors 111a open, and this, until the finalization of the installation and its delivery on site.

Then, the method 200 includes a step 230 of removing the removable part 122 from the endoskeleton 120.

The removal of the removable part 122 of the endoskeleton 120 makes it possible not to be hampered during the installation of the flexible membrane 130 inside the maritime container 110.

Then, the method 200 includes a step 240 of hooking the plurality of anchoring elements 132 of the flexible membrane 130 to the plurality of hooking elements 123 of the main part 121 of the endoskeleton 120.

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 at the level of the internal faces of the rear wall 112 and side walls 115. In this way, the flexible membrane 130 does not interfere with the access door 111a which is left free of access.

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 fastening means pass through the holes in a sealed manner connection 131 of the flexible membrane 130.

Then, the method 200 comprises a step of positioning 260 the suction pipe 140 and the filling pipe 150, so as to respectively define a sealed passage through at least one of the

walls

111, 112, 113, 114, 115 of the shipping container 110, between the flexible membrane 130 and the outside of the shipping container 110.

Then, the method 200 includes a step of closing and obturation 270, from the outside, of the access door 111a of the front wall 111.

In practice, before closing and obturation, 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 inner face of the front wall 111.

Furthermore, the access door 111a of the front wall 111 is closed by non-removable closing means, for example by welding.

Finally, the method 200 includes a step of connecting 280 the filling line 150 to a power source external to the shipping container 110 and which is suitable for delivering water.

We have described and illustrated the invention. However, the invention is not limited to the embodiments that we have presented. Thus, an expert in the field can deduce other variants and embodiments, on reading the description and the appended figures.

The invention may be subject to numerous variants and applications other than those described above. In particular, unless otherwise indicated, the various 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. In addition, 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.

For example, depending on the needs, apart from the removable part 112 of the endoskeleton, the non-removable fastening means can be replaced by removable fastening means, and vice versa.

Furthermore, depending on the needs, the flexible membrane 130 can comprise the plurality of attachment elements 123 while the fire water reserve 100 can comprise the plurality of anchoring elements 132.
