Description

Dispositif de protection pour réservoir de fluide sous pression et réservoir pourvu d'un tel dispositif Protective device for a pressurized fluid reservoir and reservoir provided with such a device
La présente invention concerne un dispositif de protection pour réservoir de fluide sous pression ainsi qu'un réservoir pourvu d'un tel dispositif.The present invention relates to a protective device for pressurized fluid reservoir and a reservoir provided with such a device.
L'invention concerne plus particulièrement un dispositif de protection pour réservoir de fluide sous pression comprenant une enveloppe destinée à être disposée sur au moins une partie de la surface extérieure d'un réservoir, des moyens d'absorption d'énergie comportant une pluralité de nervures souples formées sur la surface intérieure de l'enveloppe destinée à venir en contact avec la surface extérieure d'un réservoir.The invention relates more particularly to a protection device for a pressurized fluid reservoir comprising an envelope intended to be disposed on at least a portion of the external surface of a reservoir, energy absorption means comprising a plurality of ribs. flexible formed on the inner surface of the casing intended to come into contact with the outer surface of a tank.
L'alimentation de dispositifs consommant du gaz, par exemple une pile à combustible, pose de nombreux problèmes. Il est notamment important d'assurer une simplification et la sécurisation de l'alimentation en se plaçant notamment dans le cadre du principe d'échange d'un réservoir vide par un réservoir plein.The supply of devices consuming gas, for example a fuel cell, poses numerous problems. It is particularly important to ensure simplification and securing of the power supply, particularly in the context of the principle of exchanging an empty tank with a full tank.
Ce problème est d'autant plus sensible que la tendance est à l'augmentation des pressions de service, ceci afin d'offrir un meilleur rapport entre la masse de gaz stockée et la masse totale du réservoir, conjointement à un faible encombrement.This problem is all the more sensitive as the trend is to increase operating pressures, in order to offer a better ratio between the mass of gas stored and the total mass of the tank, together with a small footprint.
De plus, la tendance est à une diffusion plus large de systèmes nécessitant l'utilisation de gaz à un public de non-spécialistes.In addition, the trend is towards a wider diffusion of systems requiring the use of gas to a non-specialist public.
Un objectif des systèmes de stockage de fluide et de leurs dispositifs de remplissage et/ou de soutirage est de rendre faciles les manipulations nécessitées par l'action d'échanger un réservoir plein contre un réservoir vide. Les systèmes de stockage doivent de plus assurer implicitement un niveau de sécurité rendant possible ces manipulations par des non-spécialistes, tout en permettant d'améliorer la sécurité et la productivité dans des centres de conditionnement.An objective of the fluid storage systems and their filling and / or withdrawal devices is to make easy the manipulations required by the action of exchanging a full tank against an empty tank. Storage systems must also implicitly ensure a level of security that makes it possible for these manipulations by non-specialists, while at the same time making it possible to improve safety and productivity in packaging centers.
Par ailleurs, la plupart des réserves de gaz livrées chez des clients sont amenées à être mobiles. Dans un cas extrême, la source de gaz autonome pourrait être amenée à être déployée et suivre l'application consommatrice de gaz, par exemple pour alimenter une pile à combustible sur un site isolé ou pour suivre des pompiers en intervention d'urgence. Chaque client ou famille de clients a ses besoins spécifiques auxquels il convient de répondre le mieux possible. Ceci a pour conséquence une complexification de l'organisation industrielle car il est nécessaire de gérer une grande diversité de produits.In addition, most gas reserves delivered to customers are likely to be mobile. In an extreme case, the stand-alone gas source could be deployed and monitor the gas consuming application, for example to fuel a fuel cell at an isolated site or to follow firefighters in emergency response. Each client or family of clients has their specific needs that must be met as best as possible.

La figure 1 représente un corps de réservoir 1 oblong présentant une partie principale cylindrique 10 et deux extrémités inférieure 11 et supérieure 12 en forme sensiblement de dôme. L'extrémité arrondie supérieure 12 dispose d'une tête 2 de remplissage et de distribution. Comme représenté, la tête 2 de remplissage et de distribution comprend notamment une interface de connexion 3, un témoin d'état de la contenance 4, un bouclier anti-chocs 5 et un orifice central 6 donnant accès à l'intérieur du réservoir 1.Figure 1 shows an elongated tank body 1 having a cylindrical main portion 10 and two lower 11 and upper ends 12 substantially domed. The upper rounded end 12 has a filling head 2 and distribution. As shown, the filling and dispensing head 2 comprises in particular a connection interface 3, a status indicator of the capacity 4, an anti-shock shield 5 and a central orifice 6 giving access to the interior of the reservoir 1.
La figure 2 présente en variante l'ensemble de stockage de gaz (réservoir) suivant le même mode de réalisation avec une enveloppe optionnelle 100 couvrant sensiblement entièrement la surface extérieure du réservoir 1. L'enveloppe 100 (ou fourreau) est prévue pour protéger le réservoir 1 contre les chocs et les chutes éventuelles.FIG. 2 alternatively presents the gas storage assembly (tank) according to the same embodiment with an optional envelope 100 covering substantially entirely the outer surface of the tank 1. The envelope 100 (or sleeve) is provided to protect the tank 1 against shocks and possible falls.
L'enveloppe oblongue 100 de dimensions adaptées au réservoir 1 fait correspondre son extrémité arrondie inférieure 111 avec l'extrémité inférieure 11 du réservoir 1. La partie centrale cylindrique de l'enveloppe 100 épouse la partie cylindrique 10 du réservoir 1. L'extrémité supérieure arrondie 112 de l'enveloppe recoure quant à elle l'extrémité supérieure 12 du réservoir 1.The oblong envelope 100 of dimensions adapted to the tank 1 matches its lower rounded end 111 with the lower end 11 of the tank 1. The cylindrical central portion of the envelope 100 matches the cylindrical portion 10 of the tank 1. The upper end rounded 112 of the envelope recourse in turn the upper end 12 of the tank 1.
Des fentes 102 situées sur la périphérie de l'extrémité supérieure 112 de l'enveloppe permettent d'enfiler l'enveloppe 100 sur le réservoir 1.Slots 102 located on the periphery of the upper end 112 of the casing make it possible to thread the casing 100 onto the reservoir 1.
A l'extrémité supérieure de l'enveloppe 100, un collier 103 équipé d'un fermoir 104 (de type ruban d'accrochage ou bouton pression ou tout autre moyen équivalent) peut être prévu pour immobiliser l'enveloppe 100 sur le réservoir 1.At the upper end of the casing 100, a collar 103 equipped with a clasp 104 (of the type of fastening tape or snap fastener or any other equivalent means) may be provided for immobilizing the casing 100 on the reservoir 1.
L'enveloppe 100 comporte sur sa périphérie des empreintes ergonomiques 101 permettant une bonne préhension de l'ensemble. L'enveloppe 100 est de préférence réalisée en mousse haute densité thermo-formée mais tout autre matériau peut être envisagé tel que du Néoprène, une matière élastomère, etc..The envelope 100 has on its periphery ergonomic impressions 101 allowing a good grip of the assembly. The envelope 100 is preferably made of thermo-formed high-density foam but any other material may be envisaged such as neoprene, an elastomeric material, etc.
La figure 3 représente un réservoir sur lequel est connectée une tête de délivrance de fluide 150. Le réservoir 1 est guidé et enfermé dans une autre forme de réalisation de dispositif de protection ou enveloppe 100. Le dispositif de protection 100 possède un fond rapporté 133. L'enveloppe 100 forme un étui creux et comporte sur sa surface intérieure au moins une zone comportant des lamelles ou nervures souples longitudinales 328 (cf. figure 6). De préférence, les lamelles s'étendent longitudinalement sur sensiblement toute la longueur de l'enveloppe 100.FIG. 3 shows a reservoir on which a fluid delivery head 150 is connected. The reservoir 1 is guided and enclosed in another embodiment of a protective device or envelope 100. The protection device 100 has an attached bottom 133. The envelope 100 forms a hollow case and has on its inner surface at least one area with longitudinal flexible strips or ribs 328 (see Figure 6). Preferably, the lamellae extend longitudinally over substantially the entire length of the casing 100.
Les lamelles 328 solidaires de sa paroi interne permettent à la fois d'immobiliser un réservoir 1 dans l'enveloppe 100 et de compenser les variations géométriques du réservoir 1 résultant notamment de sa pression interne et de ses tolérances de fabrication. Par ailleurs, les lamelles 328 permettent d'absorber l'énergie générée par un choc ou une chute du réservoir ainsi habillé. Les lamelles 328 peuvent être supplées par tout autre structure équivalente telle que des lamelles circulaires suivant le diamètre du réservoir, des picots souples, etc..The lamellae 328 integral with its internal wall make it possible both to immobilize a reservoir 1 in the casing 100 and to compensate for the geometric variations of the reservoir 1 resulting in particular from its internal pressure and its manufacturing tolerances. Furthermore, the strips 328 can absorb the energy generated by a shock or a fall of the tank thus dressed. The slats 328 may be supplemented by any other equivalent structure such as circular slats depending on the diameter of the tank, flexible pins, etc.
De même, les nervures longitudinales peuvent être continues et/ou formées par une pluralité de picots ou nervures « discrètes » formant les lignes de contact « en pointillés » sur la surface extérieure du réservoir.Similarly, the longitudinal ribs may be continuous and / or formed by a plurality of pins or "discrete" ribs forming the "dotted" contact lines on the outer surface of the tank.
De même, les lignes de nervures longitudinales peuvent être légèrement décalées angulairement par rapport à la direction longitudinale du réservoir (c'est- à-dire que l'angle entre les nervures longitudinales et l'axe longitudinal du réservoir peut être non nul et par exemple compris entre 0 et 30 degrés.Similarly, the longitudinal rib lines may be slightly angularly offset relative to the longitudinal direction of the reservoir (that is to say that the angle between the longitudinal ribs and the longitudinal axis of the reservoir may be non-zero and by example between 0 and 30 degrees.
En variante, les nervures peuvent former des lignes hélicoïdales sur la surface extérieure du réservoir.Alternatively, the ribs may form helical lines on the outer surface of the tank.
Le fond rapporté 133 de l'enveloppe 100 comprend un filet hélicoïdal 331 destiné à être vissé dans une saignée hélicoïdale 321 de l'enveloppe 100.The bottom 133 of the casing 100 includes a helical thread 331 intended to be screwed into a helical groove 321 of the casing 100.
Le fond 133 amovible permet ainsi de faciliter le montage et le serrage du réservoir 1 dans l'enveloppe 100. De plus le fond 133 amovible permet de ne pas entraver les opérations de maintenance usuelles du réservoir 1.The removable bottom 133 thus makes it easier to assemble and tighten the tank 1 in the casing 100. Moreover, the removable bottom 133 makes it possible not to hinder the usual maintenance operations of the tank 1.
La partie supérieure de l'enveloppe 100 peut comporter une empreinte femelle 522 pour permettre de positionner et d'indexer en rotation le réservoir 1 par rapport à la dite enveloppe 100. De cette façon, il est par exemple possible de faire correspondre un témoin d'état de contenance et des organes de sécurité (soupape de décharge, fusible thermique, disque de rupture, etc. ...) dudit réservoir 1 avec des ouvertures correspondantes de l'enveloppe 100.The upper part of the envelope 100 may comprise a female cavity 522 to allow the reservoir 1 to be positioned and indexed in rotation relative to said envelope 100. In this way, it is for example possible to match a control of state of containment and safety devices (relief valve, thermal fuse, rupture disc, etc. ...) of said tank 1 with corresponding openings of the casing 100.
Les figures 4 et 5 décrivent des caractéristiques et des fonctions avantageuses de l'enveloppe 100 de réservoir. L'enveloppe 100 comporte un orifice 323 permettant de visualiser, par exemple, un état du témoin de contenance du réservoir 1. Un autre orifice 324 de l'enveloppe (par exemple prédécoupé dans le corps de l'enveloppe) peut être prévu pour disposer optionnellement d'un canal d'évacuation pour un organe de sécurité du réservoir (par exemple une soupape de décharge, un fusible thermique, un disque de rupture ou tout autre système analogue).Figures 4 and 5 describe advantageous features and functions of the tank shell 100. The envelope 100 comprises an orifice 323 making it possible to visualize, for example, a state of the reservoir capacity indicator 1. Another orifice 324 of the envelope (for example pre-cut in the body of the envelope) may be provided to dispose of optionally an evacuation channel for a tank safety member (for example a relief valve, a thermal fuse, a rupture disc or any other similar system).
L'enveloppe 100 comprend quatre organes de préhension :The envelope 100 comprises four gripping members:
- une poignée supérieure 325,an upper handle 325,
- une sangle d'épaule 326- a shoulder strap 326
- une poignée souple 327, eta flexible handle 327, and
- une poignée de fond 332.- a bottom handle 332.
Les organes de préhension sont prévus pour permettre de porter et/ou déplacer et/ou positionner et/ou orienter le réservoir dans différentes configurations, dont celles décrits ci-après.The gripping members are provided to allow to carry and / or move and / or position and / or orient the reservoir in different configurations, including those described below.
Dans une première configuration, le réservoir équipé de l'enveloppe 100 peut être couché ou maintenu debout. Pour ce faire, le réservoir 1 peut être levé ou déplacée via la poignée supérieure 325 de l'enveloppe 100.In a first configuration, the tank equipped with the envelope 100 can be laid down or held upright. To do this, the tank 1 can be lifted or moved via the upper handle 325 of the casing 100.
L'utilisation conjointe de la poignée supérieure 325 et la poignée de fond 332 peut permettre de transporter ou de positionner le réservoir pour le présenter, par exemple, dans un système receveur ou dans une cellule de stockage horizontal.The joint use of the upper handle 325 and the bottom handle 332 may allow the container to be transported or positioned for display, for example, in a receiving system or in a horizontal storage cell.
Le réservoir peut également être transportée via la sangle 326 d'épaule (qui est de préférence élastique ou enroulable/déroulable à partir d'un enrouleur du type de ceux utilisés par exemple pour les ceintures de sécurité de véhicules).The reservoir can also be transported via the shoulder strap 326 (which is preferably elastic or rollable / unrollable from a retractor of the type used for example for vehicle seat belts).
Le réservoir peut en outre être transporté via la poignée souple 327. Avantageusement, la poignée souple 327 a des dimensions choisies de façon à faire saillie par rapport à la sangle d'épaule 326. De cette façon, la poignée souple 327 et la sangle d'épaule 326 peuvent être placé dans une même zone et peuvent être attrapées l'une ou l'autre sans difficulté et sans risque de confusion ou de mauvaise manipulation.The reservoir can also be transported via the flexible handle 327. Advantageously, the flexible handle 327 has dimensions chosen so as to project relative to the shoulder strap 326. In this way, the flexible handle 327 and the shoulder strap shoulder 326 can be placed in the same area and can be caught either without difficulty and without risk of confusion or mishandling.
De plus, l'enveloppe 100 (et donc le réservoir 1 ) peut être prise via la poignée de fond 332, par exemple pour son extraction hors d'un système receveur ou d'une cellule de stockage horizontale. Par ailleurs, l'enveloppe 100 peut assurer au réservoir 1 qu'elle habille une grande stabilité. En effet, les formes extérieures de l'enveloppe 100 peuvent être prévues pour faciliter plusieurs positions stables de pose.In addition, the envelope 100 (and thus the reservoir 1) can be taken via the bottom handle 332, for example for its extraction out of a receiving system or a horizontal storage cell. Furthermore, the envelope 100 can ensure the tank 1 that it dresses a great stability. Indeed, the outer forms of the envelope 100 can be provided to facilitate several stable positions of installation.
Par exemple, deux nervures 1328, 329 longitudinales peuvent coopérer avec une nervure transversale 330 pour former une zone stable de l'enveloppe 100 en position horizontale couchée. Dans cette position couchée allongée, les différents organes de préhension sont facilement accessibles et toute autre position assure la limitation de la possibilité de roulement de l'enveloppe 100.For example, two longitudinal ribs 1328, 329 can cooperate with a transverse rib 330 to form a stable zone of the casing 100 in horizontal supine position. In this extended lying position, the various gripping members are easily accessible and any other position ensures the limitation of the possibility of rolling the envelope 100.
La structure 333 du fond 33 de l'enveloppe 100 peut également former une zone d'appui stable pour la position verticale. En particulier, la forme 333 concave du fond 33 peut définir une zone d'appui circulaire qui facilite sa stabilité sur un sol irrégulier.The structure 333 of the bottom 33 of the envelope 100 can also form a stable support zone for the vertical position. In particular, the concave form 333 of the bottom 33 may define a circular bearing zone which facilitates its stability on an uneven ground.
Ainsi, la forme de l'enveloppe 100 permet de sécuriser le réservoir en position de stockage, quelle soit horizontale ou verticale. Deux orifices 334 peuvent être prévus à la base de l'enveloppe 100 pour coopérer avec au moins un axe de positionnement ou de fixation solidaires d'un bâti (non représenté). De cette façon, le réservoir peut être parfaitement maintenu et/ou positionné verticalement.Thus, the shape of the envelope 100 makes it possible to secure the reservoir in the storage position, whether horizontal or vertical. Two orifices 334 may be provided at the base of the casing 100 to cooperate with at least one positioning or fixing axis integral with a frame (not shown). In this way, the tank can be perfectly maintained and / or positioned vertically.
La forme de l'enveloppe 100 permet, en outre, un stockage de plusieurs enveloppes de façon adjacente en rendant possible leur l'imbrication de leurs volumes.The shape of the envelope 100 further allows a storage of several envelopes adjacent by making possible the nesting of their volumes.
De plus, la géométrie de l'enveloppe 100 offre à l'utilisateur des surfaces d'information 335 judicieusement orientées.In addition, the geometry of the envelope 100 offers the user information surfaces 335 judiciously oriented.
Selon les besoins de l'utilisation, la nature du fluide stocké dans le réservoir, l'enveloppe 100 peut avoir des propriétés isothermes, permettant de maintenir un réservoir à une température dont la plage de variation doit être réduite.Depending on the needs of use, the nature of the fluid stored in the reservoir, the envelope 100 may have isothermal properties, to maintain a reservoir at a temperature whose range of variation must be reduced.
De préférence, l'enveloppe comporte au moins deux orifices distincts destinés à former un circuit de ventilation du gaz situé dans l'enveloppe. Ces orifices, par exemple situés respectivement en partie supérieure et inférieure de l'enveloppe 100, permettent une évacuation des fuites de gaz du réservoir et empêchent ainsi leur stagnation entre le réservoir et l'enveloppe 100. L'invention peut s'appliquer à toutes les utilisations de fluide demandant une grande facilité d'emploi, un bon compromis légèreté, encombrement et capacité (autonomie). Par exemple : l'hydrogène gazeux pour pile à combustible portable ou mobile, les gaz médicaux, les gaz pour analyses et laboratoires. Preferably, the envelope comprises at least two separate orifices intended to form a gas ventilation circuit located in the envelope. These orifices, for example located respectively in the upper and lower part of the casing 100, allow evacuation of gas leaks from the reservoir and thus prevent their stagnation between the reservoir and the casing 100. The invention can be applied to all fluid applications requiring ease of use, a good compromise lightness, size and capacity (autonomy). For example: hydrogen gas for portable or mobile fuel cells, medical gases, gases for analysis and laboratories.
