Definitions
- the present invention relates to the destruction of dangerous objects such as shells or other ammunition.
- the invention relates in particular to the field of demilitarization and more generally to all sectors of environmental protection. It relates in particular to a secure preparation device for destruction by confined explosion of dangerous objects and the method of producing and implementing such a device.
- the destruction of toxic products must necessarily be done in a closed environment to prevent the spread of toxic molecules and their degradation products often themselves very dangerous (arsenic for example).
- the simultaneous presence of the explosive charge and the toxic products makes the delicate and dangerous neutralization operations.
- the difficulty is at its height when the munitions in question are in a state that does not allow their disassembly, either because of their corrosion, or because their firing system is already aligned ie armed and triggered.
- One of the most effective and versatile methods is to surround the munition with massive explosive charges and detonate the whole thing in an armored detonation chamber.
- the heat and the shock wave fracture the ammunition and destroy its explosive and / or toxic contents.
- the major drawback of the method lies in the large number of manual operations required: preparation of the ammunition and additional charges, setting up the ignition line, loading the chamber, these operations must be done most often in protective clothing.
- the invention proposes simple and economical means for enabling the remote operation of the method described above and thus safeguarding the safety of the operators.
- the invention also makes it possible to increase the rate of destruction of the charges.
- the invention proposes a device for destroying dangerous objects such as shells, ammunition or other charges to be destroyed by detonation, comprising a package made from a blank folded on itself in at least three folds, four or more folds to form at least three panels and two half-panels, four sides or four sides and a closure flap of the packaging made in the form of a tubular package of polygonal section and in particular square or rectangular once the blank folded, loads explosives disposed on the sides to be folded, said blank being of suitable dimensions to accommodate, in the center of the tubular packaging and in contact with the explosive charges, one or more of said dangerous objects to be destroyed.
- support plates attached to the panels are interposed between the explosive charges and said panels, the plates
- the support being of a width such that they leave portions of free sides to allow the folding of the blank.
- the support plates are advantageously flexible polymer foam plates.
- the support plates are preferably of thickness adapted to the diameter of the explosive charges and the charge or charges to be destroyed so as to maintain said charges in contact.
- the blank is advantageously a cardboard blank provided with fold lines to reduce the cost of the package.
- the blank is a foam blank of polymer foam provided with folding precuts.
- the polymeric foam is advantageously a polyurethane foam.
- the device advantageously comprises means for fixing the explosive charges on the panels.
- the device advantageously comprises handling straps.
- the device comprises a line of ignition of the explosive charges.
- the invention further relates to a method of making a package for destroying dangerous objects such as shells, ammunition or other objects to be destroyed by detonation which comprises:
- flexible foam plates are positioned on the sides of the unfolded blank before the explosive charges are laid, the explosive charges themselves being placed on the plates.
- the blank is made of foam and is previously provided with folding precuts and slots for receiving lashing straps.
- the explosive charges are preferably fixed on the panels or plates by lashing straps.
- the method advantageously comprises a step of equipping the package with handling straps, a step of attaching the package to a handling machine by means of the handling straps, the attachment of the package by the handling straps in a chamber of detonation then the detonation of the package by means of the ignition line.
- Figure 1 a perspective view of a device made according to the invention after laying explosive charges and a charge to be destroyed;
- FIG. 2 a perspective view of the device of FIG. 1 before laying explosive charges
- FIG. 3 front views of an exemplary embodiment of a device according to the invention according to several production steps;
- FIGS. 6A to 6G front views of non-limiting embodiments of devices of the invention.
- FIGS 7A and 7B perspective views of a second embodiment of the invention unfolded and folded
- Figure 8 a perspective view of a polygonal section package.
- the present invention proposes the constitution of a pre-equipped conditioning means comprising explosive charges and an ignition line.
- the charge or charges to be destroyed can then be deposited on this means which, by a simple remote control operation comes to constitute a package to be introduced into a detonation chamber to explode.
- An advantage of the invention is that the explosive charges and the ignition line being new pyrotechnic objects, they can be handled directly by an operator in accordance with the safety standards and in particular compliance with the maximum quantities of explosive present.
- the pre-equipped conditioning means of the invention performs in particular the following functions:
- FIG. 1 represents an exemplary embodiment of a device according to the invention before folding.
- a blank 10 for example a standard thick packing cardboard plate, blocks of foam 40, 41 are glued.
- the blank may in particular be a strong carton for 10 mm thick triple-groove packaging whose main fiber (the axis of the grooves) is positioned perpendicular to the axis of the ammunition to prevent sagging of the package once folded.
- the blank may include imprints of fold lines.
- the foam plates 40, 41 are, for example, polymer foam plates such as a standard polyurethane foam of 48 kg / m 3 type for the plate supporting the ammunition, 24 kg / m 3 for the other parts of the unfolded packaging.
- the foam boards are simply glued (by self-adhesive strips or a spray glue for example) onto the carton of the package.
- the blank can be deposited on a polyacrylate plate-type support plate with a thickness of 16 mm and a width of 60 mm.
- Blocks of explosive forming the explosive charges 20, 21 are fixed on the support plates such as foam blocks using means for fixing the explosive charges of small straps type 50 preferably provided with self-gripping means but also to be elastic.
- explosive charges are explosive charges used in mines and quarries, for example emulsion type.
- the blank comprises fold lines p1, p2, p3, p4 defining sections 1 1, 12, 13, 14a, 14b and the load to be destroyed, here a shell 100 which is placed on the explosive charges arranged on a main panel 1 1 of the device around which the blank will be folded.
- Figure 2 shows the blank equipped with support plates 40, 41 without the explosive charges.
- the main panel 1 1 and its support plate 40 is wider than the side panels 12, 13 and the end panels 14b, 14c intended to provide the upper face of the package. These side and extreme sides receive plates of reduced width 41.
- the plates 40, 41 received by the panels are cut to have a reduced width relative to the panels to allow the folding of the tubular box-shaped packaging.
- the means 50 for fixing the explosive charges of the straps type for example in two parts provided with self-gripping material (known for example under the trademark Velcro) or elastic, are mounted on the blank and pass through slots in the support plates.
- self-gripping material known for example under the trademark Velcro
- elastic are mounted on the blank and pass through slots in the support plates.
- the device further comprises an ignition line 60 which is a standard device consisting of an electric detonator 61 or initiator and a detonating charge 62 or booster.
- This ignition line is responsible for simultaneously igniting all the additional charges 20, 21.
- the initiator and the detonating charge are placed at one end of the box, where the compression action of the foam blocks will squeeze the explosive bars against them.
- An electrical wire 63 connecting the detonator to a control module 64 is folded onto one of the sidewalls of the box and held by fasteners, for example straps made of self-gripping material. The control module 64 connected to the initiator by the wire 63 can thus be moved away from the box.
- the emplacement of the explosive charges such as explosive bars, as well as the setting of the ignition line can be done manually in an ad hoc room on the plate equipped with support plates and explosive charges. Once the plate thus prepared, it is transferred to a room dedicated to operations involving the handling of the loads to be destroyed. There the dangerousness of the operations imposes the remote handling.
- the foam plates 40, 41 and explosive charges 20, 21 are arranged in such a way that they have a recess allowing a stable and teleoperated removal of the charge to be destroyed.
- the ammunition (s) to be destroyed are taken from the stock and deposited on the explosive charges of the main blank.
- the device is then closed by a folding machine. Closing the package that is the packaging equipped with its explosive charges and containing the dangerous object to be destroyed is for example provided by an adhesive tape.
- FIG. 3 The steps of the method of implementation of the device of the invention are shown schematically in FIG. 3 and include:
- step A placing the ammunition receiving blank unfolded and provided with its support plates which here comprise 45 ° side cuts to allow folding of the blank according to its fold lines;
- step B placing explosive charges according to an arrangement of thick and thin charges ensuring good coverage of the charge to be destroyed once the package has been folded and then put in place an ignition line;
- step C removal of the ammunition or charges to be destroyed on the pan around which the package will be folded;
- Steps D, E, F progressive closure of the package according to fold lines p2, p3 to fold the side panels 12, 13 around the main panel 1 1 and p1, p4 to fold the upper half panels 14a, 14b;
- step F the foam plates firmly apply the explosive charges to the load to be destroyed.
- the finished package is made in the form of a tubular box, here square or rectangular section shown in Figure 4 with handling straps 51 for example previously fixed under the blank so that their stall and the establishment of these is possible with one movement;
- the following process involves the attachment of the box or package to a handling machine by means of the straps 51 and the establishment of the box in a detonation chamber 70 as shown in Figure 5 by the handling machine that can to be a robot driven remotely.
- the set of selected materials meets two requirements: a minimum cost, considering that the box is for single use, and a reduction in the gaseous volume emitted during the combustion of the box in the room. This latter requirement generally corresponds to the definition of a maximum permissible mass and a maximum organic matter content.
- FIGS. 6A to 6G provide a non-limiting view of the possible arrangements for:
- FIGS. 6B and 6C two possible arrangements for two medium ammunition 101.
- the arrangement of FIG. 6B corresponds to a box formed in four folds p1, p2, p3, p4 with two half-panels 14a, 14b on the upper face
- the arrangement of FIG. 6C corresponds to a box formed in three folds p1, p2, p3 with a pan 14 on the upper side folded from a first side face 12 and secondly joining a side face 13.
- This box further comprises a bottom foam plate provided with a cutout 44 for driving an explosive charge 20 and thus to bring the charges to destroy;
- FIGS. 6D and 6E show two arrangements made for large munitions 103, the arrangement of FIG. 6D placing thick charges at the corners of the box while the arrangement of FIG. 6E places them on lateral faces embedded in cutouts of the side plates;
- FIGS. 6F and 6G also show arrangements for large munitions 103 which provide arrangements of thick and thin explosive charges 21 for responding to various situations depending on the strength of the charge to be destroyed.
- the device of the invention can evolve especially in the use of foam blocks of different density to avoid crushing by the weight of the ammunition, a definition of the box dimensions corresponding to the various calibers, with compatible boxes of 2 or 3 ammunition for small calibres, the use of straps folded along the box to allow their capture and deployment by a manipulator robot, the use of a connection system of the ignition line 60, the possibility of being able to simultaneously introduce several boxes in a detonation chamber using a tray holder box, plate of plastic acrylate alveodiae for example. In this case an ignition line common to all boxes and fixed on the tray can be used.
- Figure 7A is a variant for which the blank 10 'is directly made of foam and provided with cuts between the sections in the form of grooves V 1 6 adapted to achieve areas of reduced thickness to fold the blank according to four sections for producing the tubular package according to FIG. 7B.
- the means 50 for fixing the loads are constituted by straps inserted in slots of the foam and closing on the explosive charges.
- FIGS. 7A and 7B comprises a support plate 55 which can also be used in the case of the example of FIG. 1 and which can in particular comprise means for retaining the handling straps.
- FIG. 8 shows a polygonal section packaging here hexagonal comprising sections 1 1 to 1 1 e of identical size, in this example the sections are made directly in the foam blank provided with grooves V 1 6 folding as the blank of Figure 7A.
- a blank is made of a sufficiently dense foam to dispense with a cardboard blank on which foam plates are arranged.
- the hexagonal geometry makes it possible to distribute the charges more evenly around the object to be destroyed and it is conceivable in the context of the invention to further increase the number of panels.
- the invention can be used for the preparation for the destruction by detonation of any dangerous object, whose dismantling by other means would be risky or too expensive.
- the invention is capable of being easily adapted to objects of various shapes and sizes and varied in the context of the destruction by detonation of dangerous products that is suitable for the destruction of a large number of toxic molecules.
