Description

DISPOSITIF DE PROTECTION D'UN RECIPIENT ET RECIPIENT EQUIPE DE DEVICE FOR PROTECTING A CONTAINER AND CONTAINER PROVIDED WITH
CE DISPOSITIFTHESE MEASURES
La présente invention concerne un dispositif de protection d'un récipient et un récipient équipé de ce dispositif. II est devenu courant d'utiliser des matériaux composites pour réaliser des récipients destinés à contenir un fluide sous pression. Ces récipients peuvent être des cuves, des réservoirs ou des bouteilles, et peuvent être réalisés notamment en fibres de verre, d'aramide ou de carbone noyées dans une matrice. Ce type de récipient comprend généralement une paroi latérale cylindrique et des extrémités arrondies, couramment dénommées "dômes", ainsi qu'un embout de raccordement situé au sommet de l'un et/ou l'autre de ces dômes.The present invention relates to a device for protecting a container and a container equipped with this device. It has become common to use composite materials to make containers intended to contain a fluid under pressure. These containers can be tanks, reservoirs or bottles, and can be made in particular from glass, aramid or carbon fibers embedded in a matrix. This type of container generally comprises a cylindrical side wall and rounded ends, commonly called "domes", as well as a connection end piece located at the top of one and / or the other of these domes.
Ces matériaux composites ont de nombreux avantages pour cette application mais ont toutefois pour inconvénient d'avoir des résistances très variables aux chocs et aux chutes des récipients, selon la nature des fibres utilisées. En particulier, les récipients réalisés par enroulement filamentaire de fibres de carbone sont très sensibles à de tels chocs ou chutes.These composite materials have numerous advantages for this application but have the drawback, however, of having very variable resistance to impacts and to drops from the containers, depending on the nature of the fibers used. In particular, the containers produced by filament winding of carbon fibers are very sensitive to such shocks or drops.
Les bases des dômes sont les parties les plus minces de la paroi d'un récipient et donc les plus fragiles. Un choc ou une chute sur un de ces dômes produit un délaminage des couches internes du matériau composite, qui conduit à une baisse de la tenue mécanique du récipient à la pression du fluide et, par conséquent, à un risque de rupture de ce récipient.The bases of the domes are the thinnest parts of the wall of a container and therefore the most fragile. An impact or a fall on one of these domes produces delamination of the internal layers of the composite material, which leads to a reduction in the mechanical resistance of the container to the pressure of the fluid and, consequently, to a risk of rupture of this container.
Pour solutionner ce problème, il a été imaginé, sur un récipient obtenu par bobinage de fibres, de placer un insert de protection en matériau absorbeur ou amortisseur de chocs ou d'impacts, notamment une mousse de polyuréthanne, sur chaque dôme de ce récipient, puis de recouvrir cet insert par un enroulement extérieur de fibres de renfort noyées dans une matrice. Ce procédé donne globalement satisfaction tout en conservant divers inconvénients, à savoir :To solve this problem, it has been imagined, on a container obtained by winding fibers, to place a protective insert made of shock absorbing or impact absorbing material, in particular a polyurethane foam, on each dome of this container, then cover this insert with an outer winding of reinforcing fibers embedded in a matrix. This process is generally satisfactory while retaining various drawbacks, namely:
- une durée de bobinage augmentée ;- an increased winding time;
- des couches de recouvrement de l'insert qui constituent de la matière supplémentaire ne participant pas à la tenue du récipient à la pression du fluide et alourdissant ce récipient ; - un amincissement de l'insert au niveau de ses extrémités, c'est-à-dire en direction de la paroi latérale du récipient d'une part et en direction du sommet du dôme d'autre part, pour permettre le recouvrement de cet insert sans que les couches de recouvrement ne subissent des ruptures de niveau ; cet insert protège par conséquent le récipient essentiellement contre des chutes "obliques", c'est-à-dire avec l'axe du récipient formant un angle d'environ 45° avec la surface d'impact, mais ne protège pratiquement pas ce récipient contre des chocs se produisant au niveau du sommet du dôme, dans le cas d'une chute "verticale", c'est-à- dire avec l'axe du récipient sensiblement perpendiculaire à la surface d'impact, ou contre des chocs se produisant au niveau de la portion de la paroi latérale du récipient adjacente à la base du dôme, dans le cas d'une chute "horizontale", c'est-à-dire avec l'axe du récipient formant un angle faible ou nul avec cette même surface d'impact. L'un ou l'autre de ces deux types de chute risque par conséquent de provoquer le délaminage interne précité de la base du dôme.- covering layers of the insert which constitute additional material which does not participate in the holding of the container at the pressure of the fluid and making the container heavier; - a thinning of the insert at its ends, that is to say towards the side wall of the container on the one hand and towards the top of the dome on the other, to allow the recovery of this insert without covering layers undergoing level breaks; this insert consequently protects the container essentially against "oblique" falls, that is to say with the axis of the container forming an angle of about 45 ° with the impact surface, but practically does not protect this container against shocks occurring at the top of the dome, in the case of a "vertical" fall, that is to say with the axis of the container substantially perpendicular to the impact surface, or against shocks producing at the portion of the side wall of the container adjacent to the base of the dome, in the case of a "horizontal" fall, that is to say with the axis of the container forming a small or zero angle with that same impact surface. Either of these two types of fall therefore risks causing the abovementioned internal delamination of the base of the dome.
La présente invention vise à remédier à ces inconvénients, en fournissant un dispositif de protection simple et peu onéreux à mettre en oeuvre, n'alourdissant pas significativement le récipient, et assurant une parfaite protection de ce récipient en cas de chute, quel que soit l'angle que forme l'axe de ce récipient avec la surface d'impact.The present invention aims to remedy these drawbacks by providing a simple and inexpensive protection device to implement, not significantly weighing down the container, and ensuring perfect protection of this container in the event of a fall, whatever the angle formed by the axis of this container with the impact surface.
A cet effet, ce dispositif de protection comprend :To this end, this protection device includes:
- une coque en matériau résistant au poinçonnement, conformée pour envelopper au moins l'ensemble d'un dôme du récipient, en délimitant un espace entre sa face interne et la face externe de la paroi du récipient ; et- A shell of material resistant to punching, shaped to envelop at least the whole of a dome of the container, delimiting a space between its internal face and the external face of the wall of the container; and
- un matériau compressible propre à amortir un choc ou un impact, remplissant l'intégralité de l'espace précité.- a compressible material capable of absorbing a shock or impact, filling the entire aforementioned space.
Ce dispositif est donc réalisé de manière indépendante du récipient, c'est-à-dire sans mise en place d'un insert de protection et bobinage de fibres lors de la fabrication du récipient. Par sa forme qui enveloppe au moins l'ensemble du dôme, et par le remplissage intégral de l'espace existant entre ladite coque et la paroi du récipient, le dispositif assure une parfaite répartition des impacts que le récipient peut être amené à subir, avec éventuelle compression du matériau compressible pour amortir ce choc au moment de cet impact. Il en résulte que ce dispositif permet de protéger efficacement le dôme du récipient quel que soit l'angle que forme, au moment d'un impact, l'axe de ce récipient avec la surface d'impact.This device is therefore produced independently of the container, that is to say without the installation of a protective insert and winding of fibers during the manufacture of the container. By its shape which envelops at least the whole of the dome, and by the complete filling of the space existing between said shell and the wall of the container, the device ensures a perfect distribution of the impacts that the container can be brought to undergo, with possible compression of the compressible material to absorb this shock at the time of this impact. As a result, this device makes it possible to effectively protect the dome of the container whatever the angle that the axis of this container forms with the impact surface at the time of impact.
La coque peut être réalisée notamment en résine synthétique, notamment en résine thermoplastique telle que acrylonitrile-butadiène- styrène ou polycarbonate, tandis que ledit matériau compressible peut être du polystyrène expansé, une mousse de polyuréthanne ou de polyéthylène, ou toute autre matière synthétique expansée.The shell can be made in particular of synthetic resin, in particular of thermoplastic resin such as acrylonitrile-butadiene-styrene or polycarbonate, while said compressible material can be expanded polystyrene, a polyurethane or polyethylene foam, or any other expanded synthetic material.
Avantageusement, le dispositif est conformé pour recouvrir non seulement l'ensemble du dôme du récipient, mais également la portion de la paroi latérale du récipient adjacente à la base de ce dôme.Advantageously, the device is shaped to cover not only the entire dome of the container, but also the portion of the side wall of the container adjacent to the base of this dome.
L'enveloppement de cette portion renforce la protection du récipient contre les chutes "horizontales".The wrapping of this portion strengthens the protection of the container against "horizontal" falls.
Le dispositif peut avoir une épaisseur sensiblement constante, c'est-à-dire que la coque peut "suivre" ainsi la paroi du récipient ; de préférence, toutefois, cette coque présente, du côté de la paroi latérale du récipient, une paroi sensiblement parallèle à l'axe du récipient et, du côté du sommet du dôme du récipient, une paroi perpendiculaire à cet axe, ces deux parois se raccordant l'une à l'autre par une zone arrondie. Par cette forme, le dispositif présente une épaisseur notablement augmentée au regard de la partie du dôme la plus mince, ce qui améliore encore la protection du récipient contre les chutes "obliques".The device can have a substantially constant thickness, that is to say that the shell can thus "follow" the wall of the container; preferably, however, this shell has, on the side of the side wall of the container, a wall substantially parallel to the axis of the container and, on the side of the top of the dome of the container, a wall perpendicular to this axis, these two walls connecting to each other by a rounded area. By this form, the device has a significantly increased thickness compared to the thinnest part of the dome, which further improves the protection of the container against "oblique" falls.
Avantageusement, le dispositif comprend, lorsqu'il est destiné à équiper un récipient comprenant un embout de raccordement situé au sommet d'un dôme, une saillie annulaire dont la hauteur est telle qu'elle s'étend au-delà de l'extrémité libre de cet embout lorsque le dispositif est placé sur ce dôme.Advantageously, the device comprises, when it is intended to equip a container comprising a connection end piece located at the top of a dome, an annular projection whose height is such that it extends beyond the free end of this tip when the device is placed on this dome.
En cas de chute "verticale", cette saillie permet de protéger parfaitement l'embout contre tout impact direct. Le dispositif peut être fixé de manière inamovible sur le récipient, par tout moyen approprié, notamment par collage ; il peut également être monté de manière amovible sur ce récipient, pour permettre une inspection périodique de la paroi de ce dernier.In the event of a "vertical" fall, this projection makes it possible to protect the tip perfectly against any direct impact. The device can be fixed irremovably to the container, by any suitable means, in particular by gluing; it can also be removably mounted on this container, to allow a periodic inspection of the wall of the latter.
Selon une forme de réalisation préférée de l'invention, utilisable sur des récipients comprenant un embout de raccordement, cet embout est fileté au niveau de son extrémité libre et le dispositif est conformé pour entourer cet embout de telle sorte que la face extérieure de la coque vienne en retrait de l'extrémité libre filetée de l'embout, et comprend une bague taraudée propre à être vissée sur ledit embout et à prendre appui sur ladite coque pour assurer le montage du dispositif sur le dôme. Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du dispositif qu'elle concerne.According to a preferred embodiment of the invention, usable on containers comprising a connection end piece, this end piece is threaded at its free end and the device is shaped to surround this end piece so that the outer face of the shell comes back from the threaded free end of the end piece, and includes a threaded ring suitable for being screwed onto said end piece and to bear on said shell for mounting of the device on the dome. For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the device which it concerns.
La figure 1 en est une demi-vue alors qu'il est monté sur un réservoir, en coupe longitudinale, et les figures 2 à 4 en sont des vues en coupe longitudinale à échelle réduite, en cas de chute respectivement (i) "verticale", c'est-à-dire avec l'axe du réservoir sensiblement perpendiculaire à la surface d'impact au moment de cet impact, (ii) "oblique", c'est-à-dire avec cet axe formant un angle de sensiblement 45° avec ladite surface d'impact au moment de l'impact et (iii) "horizontale", c'est-à-dire avec cet axe formant un angle faible ou nul avec ladite surface, au moment de l'impact.Figure 1 is a half view while it is mounted on a tank, in longitudinal section, and Figures 2 to 4 are views in longitudinal section on a reduced scale, in case of fall respectively (i) "vertical ", that is to say with the axis of the reservoir substantially perpendicular to the impact surface at the time of this impact, (ii)" oblique ", that is to say with this axis forming an angle of substantially 45 ° with said impact surface at the time of impact and (iii) "horizontal", that is to say with this axis forming a slight or zero angle with said surface, at the time of impact.
La figure 1 représente une partie de la paroi latérale 1 a et de l'extrémité arrondie 1 b, dite "dôme", d'un réservoir 1 en matériau composite, ce réservoir étant équipé d'un dispositif 2 pour la protection de sa paroi contre les chocs ou les chutes.FIG. 1 represents a part of the side wall 1 a and of the rounded end 1 b, called "dome", of a tank 1 made of composite material, this tank being equipped with a device 2 for protecting its wall against shocks or falls.
Le réservoir 1 est du type destiné à contenir un fluide sous pression, et comprend une paroi 5 en matériau composite, une paroi interne de doublage 6 et un embout métallique 7 pour le raccordement de ce réservoir 1 à l'installation devant être alimentée en fluide.The reservoir 1 is of the type intended to contain a pressurized fluid, and comprises a wall 5 of composite material, an internal lining wall 6 and a metal end piece 7 for the connection of this reservoir 1 to the installation to be supplied with fluid .
L'embout 7 comprend une partie tubulaire 7a, filetée et taraudée à son extrémité libre, et une embase circulaire 7b. Le taraudage de la partie 7a permet le raccordement précité tandis que le filetage permet le vissage d'une bague taraudée 8, qui assure le montage amovible du dispositif 2 sur le réservoir 1. L'embase 7b est prise en sandwich entre les parois 5 et 6, pour assurer le montage solide de l'embout 7 sur le réservoir 1.The end piece 7 comprises a tubular part 7a, threaded and tapped at its free end, and a circular base 7b. The tapping of part 7a allows the aforementioned connection while the thread allows the screwing of a tapped ring 8, which ensures the removable mounting of the device 2 on the tank 1. The base 7b is sandwiched between the walls 5 and 6, to ensure the solid mounting of the nozzle 7 on the reservoir 1.
Le dispositif 2 comprend une coque extérieure 10, qui enveloppe l'ensemble du dôme 1 b ainsi qu'une portion de la paroi 1 a adjacente à la base de ce dôme 1 b, et un remplissage 1 1 en matériau compressible, occupant l'intégralité de l'espace délimité par la face externe de la paroi 5, par la partie 7a de l'embout 7 et par la face interne de la coque 10.The device 2 comprises an outer shell 10, which envelops the whole of the dome 1 b as well as a portion of the wall 1 a adjacent to the base of this dome 1 b, and a filling 1 1 of compressible material, occupying the entire space delimited by the external face of the wall 5, by the part 7a of the end piece 7 and by the internal face of the shell 10.
Cette dernière est en matériau résistant au poinçonnement, notamment en résine thermoplastique telle que acrylonitrile-butadiène- styrène ou polycarbonate. Elle présente, du côté de la paroi 1 a, une paroi 10a sensiblement parallèle à l'axe du réservoir 1 , et, du côté du sommet du dôme 1 b, une paroi 10b perpendiculaire à ce même axe, ces parois 10a et 10b se raccordant l'une à l'autre par une zone arrondie 10c. Il résulte de cette structure que le remplissage 1 1 présente une épaisseur importante en regard de la partie du dôme 1 b qui se trouve du côté de la paroi 1 a, partie dans laquelle ce dôme 1 b présente l'épaisseur la plus faible.The latter is made of a material resistant to punching, in particular of thermoplastic resin such as acrylonitrile-butadiene-styrene or polycarbonate. It has, on the side of the wall 1a, a wall 10a substantially parallel to the axis of the reservoir 1, and, on the side of the top of the dome 1b, a wall 10b perpendicular to this same axis, these walls 10a and 10b are connecting to each other by a rounded area 10c. It follows from this structure that the filling 1 1 has a significant thickness opposite the part of the dome 1 b which is on the side of the wall 1 a, part in which this dome 1 b has the smallest thickness.
La coque 10 comprend en outre une saillie annulaire 12 dont la hauteur est telle qu'elle s'étend au-delà de l'extrémité libre de l'embout 7 et de la bague 8 lorsque le dispositif 2 est monté sur le réservoir 1. Le matériau constituant le remplissage 1 1 est propre à amortir un choc ou un impact grâce à sa compressibilité, ce matériau pouvant être du polystyrène expansé, de la mousse de polyuréthanne ou toute autre matière synthétique expansée.The shell 10 further comprises an annular projection 12 whose height is such that it extends beyond the free end of the end piece 7 and of the ring 8 when the device 2 is mounted on the reservoir 1. The material constituting the filling 1 1 is capable of absorbing a shock or an impact thanks to its compressibility, this material possibly being expanded polystyrene, polyurethane foam or any other expanded synthetic material.
Par sa forme enveloppant non seulement le dôme 1 b mais également ladite portion de la paroi 1 a, et par le remplissage 1 1 qui occupe l'intégralité de l'espace existant entre ladite coque 10 et la paroi du réservoir 1 , le dispositif 2 assure une parfaite répartition des impacts que ce réservoir peut être amené à subir.By its shape enveloping not only the dome 1 b but also said portion of the wall 1 a, and by the filling 1 1 which occupies the entire space existing between said shell 10 and the wall of the tank 1, the device 2 ensures a perfect distribution of the impacts that this reservoir may have to undergo.
La figure 2 montre plus particulièrement que la saillie 12 protège parfaitement l'embout 7 ainsi que la bague 8, et donc la paroi du réservoir 1 , contre tout impact direct en cas de chute "verticale".FIG. 2 shows more particularly that the projection 12 perfectly protects the end piece 7 as well as the ring 8, and therefore the wall of the reservoir 1, against any direct impact in the event of a "vertical" fall.
La figure 3 montre que la paroi arrondie 10c et l'épaisseur maximale du remplissage 1 1 en regard de cette paroi 10c protègent parfaitement la partie du dôme 1 b située du côté de la paroi 1a. La figure 4 montre quant à elle que la paroi 10a assure -une parfaite protection du dôme 1 b et de la paroi 1 a en cas de chute "horizontale".Figure 3 shows that the rounded wall 10c and the maximum thickness of the filling 1 1 opposite this wall 10c perfectly protect the part of the dome 1b located on the side of the wall 1a. Figure 4 shows that the wall 10a provides perfect protection of the dome 1b and of the wall 1a in the event of a "horizontal" fall.
L'embout 7 et la bague 8 permettent le montage amovible du dispositif 2 sur le réservoir 1 , de sorte que ce dispositif 2 ne fait pas obstacle à une inspection de la paroi de ce réservoir 1 . L'invention fournit ainsi un dispositif permettant de remédier aux inconvénients des dispositifs homologues de la technique antérieure puisqu'il est simple et peu onéreux à mettre en oeuvre, qu'il n'alourdit pas significativement le récipient, et qu'il assure une parfaite protection de ce récipient en cas de chute, quel que soit l'angle que forme l'axe de ce récipient avec la surface d'impact.The end piece 7 and the ring 8 allow the removable mounting of the device 2 on the tank 1, so that this device 2 does not prevent an inspection of the wall of this tank 1. The invention thus provides a device making it possible to remedy the drawbacks of homologous devices of the prior art since it is simple and inexpensive to implement, that it does not significantly weigh down the container, and that it ensures perfect protection of this container in the event of a fall, whatever the angle between the axis of this container and the impact surface.
Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple mais qu'elle en embrasse, au contraire, toutes les variantes de réalisation. Ainsi, pour des récipients de petites dimensions, tels que des bouteilles, la face latérale extérieure de la saillie 12 peut se trouver dans le prolongement de la paroi 10a. It goes without saying that the invention is not limited to the embodiment described above by way of example but that it embraces, on the contrary, all the variant embodiments. Thus, for containers of small dimensions, such as bottles, the external lateral face of the projection 12 can be in the extension of the wall 10a.
