Description

La présente demande se rapporte à un réservoir intégrant un support d'équipements auquel sont reliés différents équipements ainsi qu'à un procédé de fabrication dudit réservoir.The present application relates to a tank integrating an equipment support to which different pieces of equipment are connected as well as to a method of manufacturing said tank.

US 3 951 362 A divulgue la structure d'un réservoir cryogénique dans un avion. US 3,951,362 A discloses the structure of a cryogenic tank in an aircraft.

Selon un mode de réalisation visible sur la figure 1, un réservoir d'hydrogène 10 comprend une enceinte extérieure 12, une enceinte intérieure 14 positionnée à l'intérieur de l'enceinte extérieure 12 ainsi que différents équipements 16, comme des conduits, des capteurs, des fils électriques par exemple, positionnés à l'intérieur de l'enceinte intérieure 14 et reliés à cette dernière.According to an embodiment visible on the figure 1 , a hydrogen tank 10 comprises an exterior enclosure 12, an interior enclosure 14 positioned inside the exterior enclosure 12 as well as various equipment 16, such as conduits, sensors, electrical wires for example, positioned inside inside the interior enclosure 14 and connected to the latter.

Selon une configuration, chaque enceinte extérieure ou intérieure 12, 14 comprend un corps tubulaire 18.1 fermé à chacune de ses extrémités par des parois d'extrémité 18.2, 18.3 en forme de dôme.According to one configuration, each exterior or interior enclosure 12, 14 comprises a tubular body 18.1 closed at each of its ends by end walls 18.2, 18.3 in the shape of a dome.

Selon un procédé de fabrication, le corps tubulaire 18.1 et une première paroi d'extrémité 18.2 de l'enceinte intérieure 14 sont assemblés. Les différents équipements 16 sont introduits à l'intérieur de l'enceinte intérieure 14 depuis l'extrémité du corps tubulaire 18.1 ouverte et sont reliés, les uns après les autres, à l'enceinte intérieure 14 par des supports (au moins un pour chaque équipement 16). Lorsque tous les équipements 16 ont été mis en place, l'enceinte intérieure 14 est fermée en reliant la deuxième paroi d'extrémité 18.3 au corps tubulaire 18.1, puis l'enceinte intérieure 14 est positionnée dans l'enceinte extérieure 12.According to a manufacturing method, the tubular body 18.1 and a first end wall 18.2 of the interior enclosure 14 are assembled. The different pieces of equipment 16 are introduced inside the interior enclosure 14 from the open end of the tubular body 18.1 and are connected, one after the other, to the interior enclosure 14 by supports (at least one for each equipment 16). When all the equipment 16 has been put in place, the interior enclosure 14 is closed by connecting the second end wall 18.3 to the tubular body 18.1, then the interior enclosure 14 is positioned in the exterior enclosure 12.

L'étape de mise en place des équipements 16 est relativement longue et impacte fortement le temps de fabrication du réservoir 10. L'intérieur de l'enceinte intérieure 14 n'étant pas très accessible, la fixation de chaque équipement 16 dans l'enceinte intérieure 14 s'avère difficile pour un opérateur. Cette difficulté est accentuée pour les derniers équipements 16 qui doivent être intégrés sans endommager les premiers équipements 16 déjà installés.The step of installing the equipment 16 is relatively long and has a significant impact on the manufacturing time of the tank 10. The interior of the interior enclosure 14 is not very accessible, the fixing of each piece of equipment 16 in the enclosure interior 14 proves difficult for an operator. This difficulty is accentuated for the last pieces of equipment 16 which must be integrated without damaging the first pieces of equipment 16 already installed.

La présente invention vise à remédier à tout ou partie des inconvénients de l'art antérieur.The present invention aims to remedy all or part of the disadvantages of the prior art.

A cet effet, l'invention a pour objet un réservoir comprenant au moins une enceinte ainsi que plusieurs équipements positionnés dans l'enceinte, l'enceinte comportant un corps tubulaire présentant des première et deuxième extrémités ouvertes ainsi que des première et deuxième parois d'extrémité reliées aux première et deuxième extrémités, le réservoir comprenant au moins un support d'équipements, auquel sont reliés les équipements, positionné dans l'enceinte et relié à l'enceinte.For this purpose, the invention relates to a tank comprising at least one enclosure as well as several pieces of equipment positioned in the enclosure, the enclosure comprising a tubular body having first and second open ends as well as first and second end walls connected to the first and second ends, the tank comprising at least one equipment support, to which the equipment is connected, positioned in the enclosure and connected to the enclosure.

Le réservoir est caractérisé en ce que :

  • le support d'équipements comprend une première extrémité reliée à la première paroi d'extrémité de l'enceinte par au moins une première liaison de type liaison par encastrement, le support d'équipements étant relié de manière rigide à la première paroi d'extrémité ;
  • le support d'équipements comprend une deuxième extrémité reliée à la deuxième paroi d'extrémité de l'enceinte par au moins une deuxième liaison ; et
  • la deuxième liaison est une liaison pivotante glissante configurée pour permettre au support d'équipements de se translater par rapport au corps tubulaire et à la deuxième paroi d'extrémité selon une direction d'introduction ainsi que de pivoter par rapport au corps tubulaire et à la deuxième paroi d'extrémité autour d'un axe parallèle à la direction d'introduction.
The tank is characterized in that:
  • the equipment support comprises a first end connected to the first end wall of the enclosure by at least one first connection of the embedding connection type, the equipment support being rigidly connected to the first end wall ;
  • the equipment support comprises a second end connected to the second end wall of the enclosure by at least one second connection; And
  • the second connection is a sliding pivoting connection configured to allow the equipment support to translate relative to the tubular body and the second end wall in an insertion direction as well as to pivot relative to the tubular body and the second end wall around an axis parallel to the direction of introduction.

Le support d'équipements n'étant pas positionné dans une enceinte lors de la fixation des équipements et étant largement accessible, la mise en place des équipements est grandement simplifiée par rapport à l'art antérieur et les risques d'endommagement des équipements positionnés les premiers sont limités.

Selon une configuration, le support d'équipements 32 comprend une première extrémité 34.1 reliée à la première paroi d'extrémité 26.1 par au moins une première liaison 36 ainsi qu'une deuxième extrémité 34.2 reliée à la deuxième paroi d'extrémité 26.2 par au moins une deuxième liaison 38.According to one configuration, the equipment support 32 comprises a first end 34.1 connected to the first end wall 26.1 by at least one first connection 36 as well as a second end 34.2 connected to the second end wall 26.2 by at least a second connection 38.

Selon un agencement, comme illustré sur la figure 6, lors de la mise en place du support d'équipements 32, la deuxième paroi d'extrémité 26.2 est reliée au corps tubulaire 24 et le support d'équipements 32 est introduit dans le corps tubulaire 24 via sa première extrémité 24.1 ouverte, la deuxième extrémité 34.2 du support d'équipements 32 étant introduite en premier. Le support d'équipements 32 est introduit dans le corps tubulaire 24 en se translatant selon une direction d'introduction parallèle à l'axe de révolution A24.According to an arrangement, as illustrated in the Figure 6 , when installing the equipment support 32, the second end wall 26.2 is connected to the tubular body 24 and the equipment support 32 is introduced into the tubular body 24 via its first open end 24.1, the second end 34.2 of the equipment support 32 being introduced first. The equipment support 32 is introduced into the tubular body 24 by translating in a direction of insertion parallel to the axis of revolution A24.

Selon un mode de réalisation, le support d'équipements 32 comprend une ossature tubulaire métallique et mécanosoudée. Bien entendu, l'invention n'est pas limitée à cette matière pour le support d'équipements 32 qui peut être réalisé en d'autres matières compatibles avec le produit stocké dans l'enceinte. De même, les éléments formant le support d'équipements 32 peuvent être reliés entre eux par toute technique d'assemblage appropriée.According to one embodiment, the equipment support 32 comprises a metal and mechanically welded tubular framework. Of course, the invention is not limited to this material for the equipment support 32 which can be made of other materials compatible with the product stored in the enclosure. Likewise, the elements forming the equipment support 32 can be connected together by any appropriate assembly technique.

Selon une configuration, le support d'équipements 32 comprend au moins trois tubes longitudinaux 40 parallèles entre eux et à l'axe de révolution A24 et reliés entre eux par des renforts 42 de manière à former un treillis. Selon un agencement, le support d'équipements 32 comprend quatre tubes longitudinaux 40 disposés à chaque sommet d'un quadrilatère dans un plan transversal (perpendiculaire à l'axe de révolution A24).According to one configuration, the equipment support 32 comprises at least three longitudinal tubes 40 parallel to each other and to the axis of revolution A24 and connected to each other by reinforcements 42 so as to form a trellis. According to one arrangement, the equipment support 32 comprises four longitudinal tubes 40 arranged at each vertex of a quadrilateral in a transverse plane (perpendicular to the axis of revolution A24).

Lorsque le support d'équipements 32 est positionné dans l'enceinte 22, chaque tube longitudinal 40 comprend une première extrémité 40.1 orientée vers la première paroi d'extrémité 26.1 ainsi qu'une deuxième extrémité 40.2 orientée vers la deuxième paroi d'extrémité 26.2.When the equipment support 32 is positioned in the enclosure 22, each longitudinal tube 40 comprises a first end 40.1 oriented towards the first end wall 26.1 as well as a second end 40.2 oriented towards the second end wall 26.2.

Chaque équipement 30, 30', 30" est relié au support d'équipements 32 par au moins une attache 48 (visible sur la figure 2) présentant une première extrémité 48.1 reliée à l'équipement 30, 30', 30", par une soudure par exemple, et une deuxième extrémité 48.2 reliée au support d'équipements 32 par une soudure par exemple. Selon un agencement, l'attache 48 comprend une zone intermédiaire 48.3 flexible positionnée entre les première et deuxième extrémités 48.1, 48.2. A titre d'exemple, une attache 48 est une bande de matière pliée en oméga pour obtenir la zone intermédiaire flexible 48.3.Each piece of equipment 30, 30', 30" is connected to the equipment support 32 by at least one fastener 48 (visible on the figure 2 ) having a first end 48.1 connected to the equipment 30, 30', 30", by a weld for example, and a second end 48.2 connected to the equipment support 32 by a weld for example. According to one arrangement, the attachment 48 comprises a flexible intermediate zone 48.3 positioned between the first and second ends 48.1, 48.2. For example, a fastener 48 is a strip of material folded in an omega shape to obtain the flexible intermediate zone 48.3.

Selon un mode de réalisation, la deuxième liaison 38 est une liaison pivotante glissante configurée pour permettre au support d'équipements 32 de se translater par rapport au corps tubulaire 24 et à la deuxième paroi d'extrémité 26.2 selon la direction d'introduction ainsi que de pivoter par rapport au corps tubulaire 24 et à la deuxième paroi d'extrémité 26.2 autour d'un axe parallèle à la direction d'introduction ou à l'axe de révolution A24.According to one embodiment, the second connection 38 is a sliding pivoting connection configured to allow the equipment support 32 to translate relative to the tubular body 24 and the second end wall 26.2 in the direction of insertion as well as to pivot relative to the tubular body 24 and the second end wall 26.2 around an axis parallel to the direction of insertion or to the axis of revolution A24.

Selon une configuration, la deuxième liaison 38 comprend un nez 50 solidaire de la tête 44, de forme cylindrique, avec une extrémité arrondie ainsi qu'un premier logement 52 solidaire de la deuxième paroi d'extrémité 26.2, plus particulièrement rapporté sur sa face intérieure F26.2, et configuré pour recevoir le nez 50 et former avec ce dernier une liaison pivotante glissante.According to one configuration, the second connection 38 comprises a nose 50 secured to the head 44, of cylindrical shape, with a rounded end as well as a first housing 52 secured to the second end wall 26.2, more particularly attached to its interior face F26.2, and configured to receive the nose 50 and form with the latter a sliding pivoting connection.

La première liaison 36 est une liaison par encastrement, le support d'équipements 32 étant relié de manière rigide à la première paroi d'extrémité 26.1. Selon un mode de réalisation visible sur la figure 5, la première liaison 36 comprend, pour la première extrémité 40.1 de chaque tube longitudinal 40, un deuxième logement 54, solidaire de la première paroi d'extrémité 26.1, dans lequel peut s'emmancher la première extrémité 40.1 du tube longitudinal 40 ainsi qu'une liaison rigide 56 reliant le tube longitudinal 40 et la première paroi d'extrémité 26.1. Selon un agencement, la première paroi d'extrémité 26.1 comprend, pour chaque tube longitudinal, une patte 58 rapportée sur la face intérieure F26.1 de la première paroi d'extrémité 26.1, traversée par un trou formant le deuxième logement 54 et présentant une face transversale 58.1 positionnée dans un plan transversal (perpendiculaire à l'axe de révolution A24) et orientée vers la deuxième paroi d'extrémité 26.2. En complément, chaque tube longitudinal 40 comprend une collerette 60 configurée pour prendre appui contre la face transversale 58.1 lorsque le tube longitudinal 40 est emmanché dans le deuxième logement 54. A titre d'exemple, la liaison rigide 56 se présente sous la forme d'une soudure reliant la collerette 60 et la face transversale 58.1, s'étendant sur toute la périphérie de la collerette 60. Bien entendu, l'invention n'est pas limitée à ce mode de réalisation pour obtenir la première liaison 36 par encastrement reliant le support d'équipements 32 et la première paroi d'extrémité 26.1.The first connection 36 is an embedding connection, the equipment support 32 being rigidly connected to the first end wall 26.1. According to an embodiment visible on the Figure 5 , the first connection 36 comprises, for the first end 40.1 of each longitudinal tube 40, a second housing 54, secured to the first end wall 26.1, in which the first end 40.1 of the longitudinal tube 40 can be fitted as well as a rigid connection 56 connecting the longitudinal tube 40 and the first end wall 26.1. According to one arrangement, the first end wall 26.1 comprises, for each longitudinal tube, a tab 58 attached to the interior face F26.1 of the first end wall 26.1, crossed by a hole forming the second housing 54 and having a transverse face 58.1 positioned in a transverse plane (perpendicular to the axis of revolution A24) and oriented towards the second end wall 26.2. In addition, each longitudinal tube 40 comprises a flange 60 configured to bear against the transverse face 58.1 when the longitudinal tube 40 is fitted into the second housing 54. For example, the rigid connection 56 is in the form of a weld connecting the flange 60 and the transverse face 58.1, extending over the entire periphery of the flange 60. Of course, the invention is not limited to this embodiment to obtain the first connection 36 by embedding connecting the equipment support 32 and the first end wall 26.1.

Selon une variante simplifiée, seule la première extrémité 34.1 du support d'équipements 32 est reliée à la première paroi d'extrémité 26.1 par une première liaison 36 de type liaison par encastrement. Selon cette variante, le support d'équipements 32 est relié en porte à faux à l'enceinte 22. Cette variante est plus particulièrement adaptée pour un support d'équipements 32 court, pour lequel sa structure treillis est suffisamment rigide pour ne pas nécessiter son maintien au niveau de sa deuxième extrémité 34.2.According to a simplified variant, only the first end 34.1 of the equipment support 32 is connected to the first end wall 26.1 by a first connection 36 of the embedding connection type. According to this variant, the equipment support 32 is cantilevered to the enclosure 22. This variant is more particularly suitable for a support equipment 32 short, for which its lattice structure is sufficiently rigid not to require it to be maintained at the level of its second end 34.2.

Le procédé de fabrication est maintenant décrit au regard des figures 2 et 6.The manufacturing process is now described with regard to the figure 2 And 6 .

Ce procédé comprend des étapes de fixation des différents équipements 30, 30', 30" sur le support d'équipements 32, comme illustré sur la figure 2, et d'assemblage du corps tubulaire 24 et de la deuxième paroi d'extrémité 26.2, comme illustré sur la partie (A) de la figure 6. Le support d'équipements 32 n'étant pas positionné dans une enceinte et étant largement accessible, la mise en place des équipements 30, 30', 30" est grandement simplifiée par rapport à l'art antérieur. De plus, les risques d'endommagement des équipements positionnés les premiers sont limités. Les étapes d'assemblage de l'enceinte 22 et de mise en place des équipements 30, 30', 30" peuvent être réalisées simultanément, ce qui permet de réduire le temps de fabrication du réservoir 20.This method includes steps of fixing the different equipment 30, 30', 30" on the equipment support 32, as illustrated in the figure 2 , and assembly of the tubular body 24 and the second end wall 26.2, as illustrated in part (A) of the Figure 6 . The equipment support 32 not being positioned in an enclosure and being widely accessible, the installation of the equipment 30, 30', 30" is greatly simplified compared to the prior art. In addition, the risks of damage to the equipment positioned first is limited. The steps of assembling the enclosure 22 and installing the equipment 30, 30', 30" can be carried out simultaneously, which makes it possible to reduce the manufacturing time of the tank 20 .

Le procédé comprend également une étape de solidarisation du support d'équipements 32 et de la première paroi d'extrémité 26.1, comme illustré sur la partie (A) de la figure 6, puis une étape d'introduction du support d'équipements 32 dans le corps tubulaire 24, comme illustré sur la partie (B) de la figure 6. Ainsi, tous les équipements sont introduits en même temps dans l'enceinte 22, contribuant à réduire le temps de fabrication du réservoir 20.The method also includes a step of securing the equipment support 32 and the first end wall 26.1, as illustrated in part (A) of the Figure 6 , then a step of introducing the equipment support 32 into the tubular body 24, as illustrated in part (B) of the Figure 6 . Thus, all the equipment is introduced at the same time into the enclosure 22, helping to reduce the manufacturing time of the tank 20.

Le nez 50 est positionné dans le premier logement 52, comme illustré sur la partie (C) de la figure 6. Enfin, la première paroi d'extrémité 26.1 étant mise en contact avec le corps tubulaire 24, le procédé comprend une étape d'assemblage de la première paroi d'extrémité 26.1 et du corps tubulaire 24 en les reliant grâce à la liaison périphérique 28, comme une soudure périphérique par exemple.The nose 50 is positioned in the first housing 52, as illustrated in part (C) of the Figure 6 . Finally, the first end wall 26.1 being brought into contact with the tubular body 24, the method comprises a step of assembling the first end wall 26.1 and the tubular body 24 by connecting them using the peripheral connection 28, like a peripheral weld for example.
