- the containment device 1 essentially comprises an envelope 2, splinter mats 3, 4 and 5, and a sleeve 6.
- the mats 3 to 5 and the sleeve 6 are arranged in the envelope 2.
- the envelope 2 is made of flexible and transparent material, for example of elastomeric polyurethane. It is particularly advantageous that the material of the envelope 2 can undergo a very high stretching before rupture. A minimum stretch of 100% or even 200% can be provided before the material breaks.
- the elastomeric polyurethane can be in the form of a thin sheet, for example less than 1 mm.
- the casing 2 has the general shape of a cylinder of revolution closed at its ends and therefore comprises a bottom wall 2a intended to rest on the ground, an upper wall 2b disposed at the end opposite to the bottom wall 2a and a wall tubular 2c connecting the end walls 2a and 2b in a sealed manner and which can be in one piece with the latter.
- the envelope 2 is completed by a retaining element 7 of the upper mat 5.
- the upper mat 5 is disposed above the upper wall 2b of the envelope 2 and is retained by the retaining element 7.
- the element retainer 7 may be in the form of a plurality of elastic straps making it possible to flexibly retain the upper mat 7.
- the retainer 7 is produced in the form of a sheet of material identical to that of the envelope 2 and fixed firmly to said envelope 2, for example by high frequency welding.
- the retaining element 7 then makes it possible to improve the seal by constituting an additional seal layer.
- a retaining element 8 of the intermediate belt 4 is also provided, which can be produced in a similar manner to the retaining element 7, and therefore preferably in the form of a sheet of material identical to the material of the envelope 2, and fixed in leaktight manner to said envelope 2.
- the retaining element 8 also forms an additional seal, increasing the probability that the seal of the envelope 2 will be maintained.
- the envelope 2 is completed by an opening 9 formed in the tubular wall 2c, at a distance from the upper wall 2b, and closed by a closure 10, for example a zipper.
- the opening 9 can extend over the greater part of the circumference of the tubular wall 2c in order to facilitate the use of the device.
- the opening 9 can be substantially parallel to the end walls 2a and 2b.
- an additional outer flap 11 is provided, which can be made of the same material as the casing 2 or of a slightly more rigid material, for example in a thicker sheet of the same material, fixed firmly, for example by welding with high frequency at the tubular wall 2c of the casing 2 above the opening 9 and coming by gravity down below the opening 9.
- the outer flap 11 is provided, at its lower end oriented towards the casing 2, a hooking zone 12 provided with multiple hooks complementary to a hooking zone 13 with multiple hooks fixed on the tubular wall 2c under the opening 9 and provided to be able to hang with the zone of attachment 12.
- the attachment zones 12 and 13 can be of the Nelcro® type. This reinforces the mechanical strength of the zipper 10, preventing it from being torn off in the event of an explosion inside the confinement device. Of course, a zipper 10 will be chosen having excellent sealing qualities.
- the splinter mats 3, 4 and 5 can be made of similar materials, for example comprising fibers with high mechanical resistance, such as aramid fibers.
- the splinter protection mats 3, 4 and 5 may comprise a plurality of protective layers and a reinforcing layer of semi-rigid material.
- the lower belt 3 is arranged at the bottom of the envelope 2 and has a flat shape.
- the upper belt 5 also has a flat shape, while the intermediate belt 4 has a flat wall 4a surrounded by a flange 4b directed downwards and making it possible to prevent the blast effect from reaching the envelope 2 too directly during an explosion inside said envelope 2, the blast effect moving upwards and therefore towards the flat wall 4a of the intermediate belt 4, then being able to move radially outwards while being at this moment limited by the peripheral rim 4b.
- the sleeve 6 is arranged on the lower mat 3 and can be made of a material similar to the splinter-proof mats 3, 4 and 5.
- the sleeve 6 has a cylinder shape adapted to the shape of the splinter-proof mat 3 to rest by its lower edge on said lower mat 3.
- the sleeve 6 can be in one piece. However, it is preferred to make the sleeve 6 in two parts.
- the sleeve 6 comprises an inner part 6a extending over the entire height of the sleeve 6 and provided with a groove on its periphery in an area close to the lower belt 3, and an outer portion 6b disposed in the aforementioned groove and having a shape complementary to the inner part 6a.
- the sleeve 6 may have a rectangular shape.
- the outer portion 6b can extend over substantially half of the total height of the sleeve 6. In the event of an explosion in an area located in the sleeve 6, the blast effect may then tend to lift the inner part 6a, while the part 6b remains in place on the lower belt 3 and prevents propagation of the chips in this direction.
- the shape of the two parts of the sleeve 6 can be produced in different ways. Two parts of the same height can be provided in the form of two concentric cylinders nested one inside the other with or without contact. One can also provide a contact surface between the two parts of the sleeve 6 having a frustoconical shape.
- the containment device can include a retention tank 14, in the form of a fluid-tight bowl placed between the lower belt 3 and the bottom wall 2a of the casing 2 and between the sleeve 6 and the side wall 2c of the envelope 2.
- the retention tank 14 can be made of waterproof material resistant to corrosive products, in particular sulfuric acid, nitric acid, hydrochloric acid.
- the retention tank 14 can be made of sentoprene®.
- the retention tank 24 includes a flat bottom 24a and an upwardly directed rim 24b. The rim 24b is provided with an articulated panel 24c which can be folded down, see FIG. 2, in the open position of the casing 2.
- the panel 14c can be articulated on the bottom 14a by means of a hinge 14d, which can simply be produced by an area of reduced thickness of the material constituting the retention tank 14.
- the articulated panel 14c can be connected to the rest of the edge 14b by elastic bellows allowing said panel to pivot between a substantially vertical position similar to that of the rest of the edge 14b and a substantially horizontal position in alignment with the bottom 14a, while retaining a seal in the position illustrated in FIG. 1 between the articulated panel 14c and the rest of the edge 14b.
- the containment device further comprises a sample collection pipe 15 fixed to the side wall 2c of the envelope 2 in a sealed manner and equipped with a valve 16.
- the containment device can be used in the following manner.
- the containment device is arranged in the open state, illustrated in FIG. 2, near an object 20 considered to be dangerous, for example an object likely to contain harmful chemical or biological substances.
- the opening 9 of the envelope 2 is then clearly released upwards and downwards.
- the articulated panel 14c of the retention tank 14 is pivoted downwards and the sleeve 6 is removed.
- the articulated panel 14c and the lower belt 3 can be provided with bevelled or chamfered ends to favor the rise of the suspect object. Provision may also be made to cover the upper surface of these elements with a material having excellent sliding qualities, for example tetrafluoroethylene. It is also possible to provisionally have a plate favoring sliding on the lateral ends of the pivoting panel 14c and of the lower belt 3 to facilitate the rise of the suspect object.
- the panel 14c can be held in the high position by hooking onto the rest of the edge 14b by means of straps, press buttons, or even multiple hook strips of the Nelcro® type.
- the sleeve 6 can be placed around the suspect object before bringing the suspect object into the envelope 2. In this way, the lateral projection of splinters is avoided as soon as possible.
- the upper part of the envelope and the intermediate 4 and upper 5 mats are placed above the sleeve 6, for example by letting them rest on the upper end of the sleeve 6, then the zipper 10 is closed and the additional flap 11 which is fixed by means of the fixing zones 12 and 13.
- the suspect object is now confined in the containment device.
- the suspect object can now be moved with reduced risk, both to people in the vicinity and to the environment.
- a possible explosion causes a blast effect which initially tends to be distributed isotropically.
- the soil generally constitutes a hard zone, the blast effect tends to spread radially and upwards. Radially, the blast effect is limited by the sleeve 6 and can then only deploy upwards.
- the blast effect then drives the upper part of the casing 2, comprising the intermediate mat 4, the upper mat 5, the retaining elements 7 and 8 and the upper wall 2b of the casing 2 upwards, causing the stretching of the side wall 2c of the envelope 2.
- a side wall 2c of a length of several meters can be provided, allowing significant deployment of the envelope 2 followed by an elastic stretching, then a stretching considerable plastic which allows the blast effect to spread upwards and therefore to weaken, the fact of projecting upwards the intermediate protective mats 4 and upper 5 also resulting in a non-negligible energy consumption tending to decrease the breath effect.
- the blast effect can also cause an upward drive of the inner part 6a of the sleeve 6.
- the lower part 6b of the sleeve 6 not directly subjected to the blast effect, remains substantially in contact with the lower belt. 3. Any splinters, the speed of movement of which is considerably lower than the speed of movement of the blast effect, are then retained laterally by the external part 6b of the sleeve 6.
- the blowing effect then directed upwards can deteriorate and even puncture the retaining element 8 and is then contained by the intermediate belt 4, in particular by the flat wall 4a of the carpet intermediate 4. Edges 4b can prevent lateral expansion of the blast effect.
- the upper wall 2b of the envelope 2 is protected by the intermediate belt 4 and therefore retains its seal.
- the retaining element 7 may meet various objects, devices and devices located in its path, for example lighting devices, a ceiling, a cable , an electrical sheath.
- the retaining element 7 can be damaged and even punctured by impact with the object located in its path, which then reaches the protective mat 5 provided to prevent such perforation, which makes it possible to protect the upper wall 2b from the envelope 2 which retains its integrity and its sealing qualities.
- the protective mat 5 provided to prevent such perforation, which makes it possible to protect the upper wall 2b from the envelope 2 which retains its integrity and its sealing qualities.
- the gaseous fraction of the chemical or biological products and the pulverulent fraction are retained by the envelope 2.
- the confinement device can be brought to a laboratory for analysis purposes.
- the laboratory can take samples through the pipe 15 and the valve 16.
- the containment device can then be brought in for destruction, for example in a secure incinerator provided for this purpose.
- the containment device makes it possible to significantly increase the safety of personnel, in particular personnel for protection and demining services, and to reduce the risk of environmental pollution, which eliminates the need for long and costly cleaning and disinfection operations.
- the containment system is well suited for suspicious objects containing radioactive substances, which it will avoid dispersion.
- the casing 2 further comprises an inner flap 19 firmly fixed to the side wall 2c of the casing 2 above the opening 9 and intended to come into contact with said side wall 2c below the closure 10 in the position illustrated in FIG. 1.
- the interior flap 19 can be made of the same material as the envelope 2. In the event of an explosion, the flap 19 is pressed against the closure 19 by the blast effect and thus increases the tightness of said closure 10.
- the containment device 1 is provided with a frame 17 disposed under the bottom wall 2a of the casing 2 and equipped with wheels 18 allowing more movement easy to contain.
- absorption elements 21 are in the form of winding pipes 22. Two pipes 22 are wound and stacked on top of each other. Provision may be made for the pipes 22 to be held in the wound position by means of fixing means, for example a flexible flange. The pipes 22 can be filled with air and closed at their ends.
- the absorption elements 21 are arranged between the bottom wall 2a of the casing 2 and the frame 17.
- the absorption elements 2 and the frame 17 can comprise metal parts without interfering with an X-ray of the suspect object.
- a pipe 22 is shown forming a wound absorption element. .
- the pipe 22 is surrounded by flexible foam 24, see FIG. 6, and placed under the splinter-proof mat 3.
- absorption elements are in the form of two windings of superimposed pipes 22, said pipes 22 having a first diameter.
- Second pipes 23 of diameter smaller than the diameter of the first pipes 22 are inserted into the pipes 22.
- the pipes 23 are also closed at their ends to trap air.
- a carriage according to a variant of the invention comprises a chassis 17 provided with wheels 18.
- the chassis 17 comprises opposite vertical side walls 25 supporting an axis 26.
- a basket is articulated on the axis 26 and comprises tie rods 27 directed downward from the axis 26 and a plate 28 supported by the tie rods 27 at a level lower than that of the axis 26.
- the plate 28 remains substantially horizontal, even when the carriage goes up or down a slope.
- the containment device 1 and the energy absorbing elements 21 are arranged on the plate 28.
- a model of trolley with two perpendicular horizontal articulations can be provided to allow the trolley to pass over sloping and sideways surfaces while while maintaining the horizontality of the plate 28.
- the sleeve 6 is produced in two concentric parts 6a and 6b, the external part 6b having a bore with a diameter greater than that of the external surface of the inner portion 6a.
- the inner portion 6a has a height greater than that of the outer portion 6b.
- the containment device further comprises a bell 30 provided with an upper wall 30a and a peripheral rim 30b, of height greater than that of the sleeve 6 and being in the form of a side skirt surrounding the sleeve 6 and the lower end of which rests on the lower belt 3.
- the bell 30 can be in the form of 'a parallelepiped open on its lower face, or a cylinder open on its lower face and closed on its upper face.
- the inner part 6a of the sleeve 6 can be covered on its bore with a fire-resistant material.
- the lower surface of the flat wall 30a and the bore of the rim 30b of the bell 30 can also be provided with a fire-resistant coating.
- the bell 30 can be made of materials similar or identical to those of the protective mats 3 to 5, and is thus able to protect the envelope 2 against splashing of splinters, corrosive products or against the effects of a fireball.
- the bell 30 makes it possible to maintain the shape of the envelope 2, the retaining element 8 being able to rest on the upper surface of the flat wall 30a of the bell 30.
- the closure of the containment device is facilitated by the presence of the bell 30 which has sufficient rigidity to support the upper part of the containment device, and to give it a shape.
- the lateral portion 2c of the envelope 2 can be provided with folds 2d in order to preserve a large axial dimension allowing an upward development of the envelope 2.
- elastic straps 29 can be provided fixed on the casing 2 to absorb energy during the axial extension of the casing 2.
- the elastic straps 29 can be fixed on the casing 2, on either side of the folds 2d or on the walls end 2a and 2b.
