The frame is composed of at least three longitudinal members 1, 2, 3, 4 whose feet 5, 6, 7, 8 on the one hand and heads 13, 14, 15, 16 on the other hand are joined by tensioning devices 9, 10, 11, 12, 17, 18, 19, 20 in order to constitute a lower regular polygon and an upper regular polygon which are parallel, superposed and angularly offset, by virtue of an inclination of the longitudinal members, by an angle sufficient for two successive longitudinal members to overlap. Tensioning devices 21, 22, 23, 24 are provided between at least some of the feet and at least some of the heads. The longitudinal members 1, 2, 3, 4 consist of tubes which are closed at both ends but are provided with an opening 29 to the outside at the feet and are connected at the heads with the central pipe 34 of a compressed air source 35.

Description

Conteneur et en particulier cage immergeable pour l'aquaculture Linvention porte sur un conteneur et en particulier une cage immergeable pour l'aquacuiture, comprenant une armature habillée d'un filet pourvu d'un moyen d'accès. Container and in particular submersible cage for aquaculture The invention relates to a container and in particular a submersible cage for aquacuiture, comprising a frame covered with a net provided with an access means.

il a été proposé plusieurs types de cages ou autres structures immergeables pour l'aquaculture, qui sont manoeuvrées à l'aide de treuils ou de ballasts remplis d'eau à immersion et vidés au moyen d'air comprimé à l'émersion.Several types of cages or other submersible structures for aquaculture have been proposed, which are maneuvered using winches or ballasts filled with immersion water and emptied by means of compressed air at emersion.

Certaines de ces cages présentent une armature parallélépipédique qui comporte ainsi au moins douze longerons, souvent rigidifiés par des membrures supplémentaires. D'autres structures à armature en forme de navette cylindroconique à ballasts toriques nécessitent, elles aussi, de nombreux longerons et autres membrures pour assurer leur rigidité et former les extrémités coniques
Toutes ces structures connues, souvent d'un volume de plusieurs dizaines de mestres cubes, exigent une main d'oeuvre importante pour leur montage ou leur démonta.ge, mais leur inconvénient majeur est d'etre d'un prix de revient prohibitif, d'un poids tres élevé et d'une manutention hors de l'eau difficile.
Some of these cages have a parallelepipedic reinforcement which thus comprises at least twelve longitudinal members, often stiffened by additional members. Other armature structures in the shape of a cylindroconical shuttle with toric ballasts also require numerous beams and other members to ensure their rigidity and form the conical ends.
All these known structures, often of a volume of several tens of cubic masters, require a large workforce for their assembly or their dismantling, but their major drawback is to be prohibitively expensive, '' a very high weight and difficult handling out of the water.

Cet inconvénient est d'autant plus sensible que les longerons et membrures travaillent à la compression, à l'extension et. à la flexion et doivent donc être d'une grande rigidité, excluant l'emploi de matériaux légers.This drawback is all the more noticeable as the side members and members work on compression, extension and. to bending and must therefore be very rigid, excluding the use of light materials.

Elles manquent enfin de souplesse et leur manutention ou les effets de: la houle en profondeur peuvent provoquer leur dislocaton.Finally, they lack flexibility and their handling or the effects of: deep swell can cause their dislocation.

L'invention a pour objet de remédier à ces inconvénients, et pour ce faire, l'armature est composée d'au moins trois longerons dont les pieds d'une part et les têtes d'autre part sont réunis par des tendeurs pour constituer un polygone régulier inférieur et un polygone régulier supérieur parallèles, superposés et décalés angulairement, grâce à une inclinaison des longerons, d'un angle suffisant pour que deux longerons successifs se chevauchent, des tendeurs étant en outre avantageusement prévus entre au moins certains des pieds et au moins certaines des têtes.The invention aims to remedy these drawbacks, and to do this, the frame is composed of at least three beams, the feet on the one hand and the heads on the other hand are joined by tensioners to constitute a lower regular polygon and upper parallel regular polygon, superimposed and angularly offset, by virtue of an inclination of the side members, of an angle sufficient for two successive side members to overlap, tensioners being advantageously also provided between at least some of the feet and at minus some of the heads.

De préférence, l'armature comprend quatre longerons, le décalage angulaire étant tel que leurs huit pieds et tettes forment en projection un octogone régulier.Preferably, the frame comprises four longitudinal members, the angular offset being such that their eight feet and tettes form in projection a regular octagon.

On conçoit que les longerons d'un tel conteneur, qui sont en très petit nombre par rapport au volume disponible ne sont solhcités qu'à la compression et peut-être exceptionnellement à la tension, mais jamais en tout cas a la flexion. II est donc possible de les réaliser en matériaux légers, et en particulier en matériaux plastiques.It is understood that the side members of such a container, which are very few in relation to the available volume, are solhcited only in compression and perhaps exceptionally in tension, but never in any case in bending. It is therefore possible to produce them in light materials, and in particular in plastic materials.

En fin de compte un tel conteneur, tout en se révélant bon marché et facile à monter, à démonter et à manoeuvrer, est d'un poids si réduit que, conformément à un mode de réalisation de l'invention particulièrement avantageux par le gain supplémentaire quil procure en matière de poids et de prix de revient, les longerons peuvent former eux-memes les ballasts s'ils sont constitués par des tubes fermés aux deux extrémités mais pourvus d'une ouverture vers l'extérieur au niveau des pieds et reliés au niveau des têtes avec la tubulure centrale d'une source d'air comprimé
Enfin les pieds peuvent être munis d'ancrages qui facilitent le contact, du conteneur avec le fond marin et évitent sa détérioration par ce fond
Un mode de réslisation de l'invention est maintenant décrit à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels: la figure 1 est, une vue en plan de l'armatue d'une cage immergeable
Pour l'aquaculture, conforme à l'invention; la figure 2 est une vue en plan de cette cage immergeable; la figure 3 3 est une vue en cavalière en élévation de la meme cage; et la figure 4 est une vue en plan de l'armature d'une cage immergeable pour l'aquaculture selon une varianté
L'armature représentée en figure 1 est essentiellement constituée de quatre longerons 1, 2, 3, 4 dont les pieds 5, 6, 7, 8 sont réunis deux par deux par des tendeurs 9, 10, 11 et 12 formant, ainsi les sommets d'un polygone inférieur, qui est ici un carré.
In the end such a container, while proving to be inexpensive and easy to assemble, disassemble and maneuver, is of such a reduced weight that, in accordance with an embodiment of the invention particularly advantageous by the additional gain which it provides in terms of weight and cost price, the side members can themselves form the ballasts if they consist of tubes closed at both ends but provided with an opening towards the outside at the feet and connected to the level of the heads with the central tube of a compressed air source
Finally the feet can be provided with anchors which facilitate contact, of the container with the seabed and prevent its deterioration by this bottom.
A mode of resolution of the invention is now described by way of nonlimiting example with reference to the accompanying drawings in which: FIG. 1 is a plan view of the armatue of a submersible cage
For aquaculture, in accordance with the invention; Figure 2 is a plan view of this submersible cage; Figure 3 3 is a side view in elevation of the same cage; and Figure 4 is a plan view of the frame of a submersible cage for aquaculture according to a variety
The frame shown in Figure 1 consists essentially of four beams 1, 2, 3, 4 whose legs 5, 6, 7, 8 are joined two by two by tensioners 9, 10, 11 and 12 thus forming the tops of a lower polygon, which here is a square.

A leur tour, les têtes 13, 14, 15 et 16 des longerons 1, 2, 3, 4 sont réunies entre elles par des tendeurs 17, 18, 19 et 20 pour constituer les sommets bu polygone supérieur, qui est un carré de même taille que le précédent.In turn, the heads 13, 14, 15 and 16 of the side members 1, 2, 3, 4 are joined together by tensioners 17, 18, 19 and 20 to form the vertices of the upper polygon, which is a square of the same size than the previous one.

Toutefois, les sommets du carré supérieur sont décalés angulairement par rapport aux sommets correspondants du carré inférieur d'environ
135
Plus précisément, la tête 13 du longeron 1 est décalée angulairement par rapport au pied 5 du même longeron 1 d'un angle de l'ordre de
135 autour de l'axe vertical central de l'ensemble.
However, the vertices of the upper square are angularly offset from the corresponding vertices of the lower square by about
135
More precisely, the head 13 of the spar 1 is angularly offset relative to the foot 5 of the same spar 1 by an angle of the order of
135 around the central vertical axis of the assembly.

Le longeron 1 occupe ainsi une position inclinée à l'intérieur de l'armature et chevauche. à environ les deux tiers de sa longueur, le longeron 2 qui occupe une même position inclinée entre son pied 6 et sa tête 14, le faisant chevaucher à son tour le longeron 3 qui, pour les mêmes raisons, chevauche le longeron 4 lequel lui-même chevauche enfin le longeron 1.The spar 1 thus occupies an inclined position inside the frame and overlaps. at about two thirds of its length, the spar 2 which occupies the same inclined position between its foot 6 and its head 14, causing it in turn to overlap the spar 3 which, for the same reasons, overlaps the spar 4 which itself even finally overlaps the beam 1.

On constate aux dessins, que dans l'exemple choisi qui comporte quatre longerons ceux-ci se trouvent deux par deux dans des plans verticaux parallèles, puisqu'ils occupent tous quatre des positions résultant l'une de l'autre d'un décalage angulaire de 900 autour du même axe vertical.It can be seen in the drawings, that in the example chosen which has four side members, these are located two by two in parallel vertical planes, since they all occupy positions resulting from each other by an angular offset of 900 around the same vertical axis.

Cette armature doit etre complétée pour constituer une structure stable pa.r des tendeurs disposés entre au moins certains des pieds 5 à 6 et certaines des têtes 13 à 16. I1 serait possible de prévoir huit tendeurs de ce type reliant un pied 5 à la tête suivante 6, puis cette tête au pied suivant 16, et ainsi de suite, mais il a été constaté aux essais qu'il est possible de se passer de la moitié de ces tendeurs et de n'en utiliser que quatre (21, 22, 23, 24) reliant chaque pied tel que 5 à la tête suivante 16.This frame must be completed to constitute a stable structure by tensioners arranged between at least some of the feet 5 to 6 and some of the heads 13 to 16. It would be possible to provide eight tensioners of this type connecting a foot 5 to the head next 6, then this head to the next foot 16, and so on, but it was found in tests that it is possible to do without half of these tensioners and to use only four (21, 22, 23, 24) connecting each foot such as 5 to the next head 16.

L'armature constitue ainsi un volume à huit sommets et à dix faces, deux des faces étant constituées par les carrés inférieur et supérieur, les huit autres faces étant des triangles qui sont alternativement du type 5, 16, 6 et dru type 16, 5, fa. The frame thus constitutes a volume with eight vertices and ten faces, two of the faces being constituted by the lower and upper squares, the other eight faces being triangles which are alternately of type 5, 16, 6 and dru type 16, 5 , fa.

Le premier type de triangle a pour base l'un des côtés 19 du carré supérieur et pour sommet le pied correspondant 5. L'autre type a pour base l'un des côtés 9 du carré inférieur et pour sommet la tête correspondante 16. The first type of triangle is based on one of the sides 19 of the upper square and the corresponding foot is at the top 5. The other type is based on one of the sides 9 of the lower square and the corresponding head 16 is at the top.

Les figures 2 et 3 montrent la cage 25 dont le filet 26 habille cette armature en épousant la forme des dix côtés ainsi décrits et en s'appuyant sur les tendeurs ou en s'incurvant naturellement là où l'on s'est dispensé de disposer un tendeur, c'est-à-dire par exemple entre la tête 16 et le pied 6.Figures 2 and 3 show the cage 25 whose net 26 covers this frame by following the shape of the ten sides thus described and by leaning on the tensioners or by bending naturally where one has dispensed with having a tensioner, that is to say for example between the head 16 and the foot 6.

Le filet 26 est pourvu d'un moyen d'accès classique 27 qui permet d'introduire ou d'extraire les animaux à élever et qui sert également de passage pour la visite intérieure éventuelle de la cage.The net 26 is provided with a conventional means of access 27 which makes it possible to introduce or extract the animals to be raised and which also serves as a passage for the possible internal visit of the cage.

Quatre ancrages 26 sont fixés aux pieds des longerons pour assurer le positionnement ferme de la cage sur les fonds marins et pour éviter son contact direct avec ces fonds qui pourraient la détériorer.Four anchors 26 are fixed to the feet of the side members to ensure the firm positioning of the cage on the seabed and to avoid its direct contact with these funds which could damage it.

Les longerons sont réalisés sous forme de tubes fermés aux extrémités et sur lesquels des moyens convenables tels que des colliers sont pfévus pour la fixation des tendeurs et des pieds Ils sont pourvus, au veisinage de leurs pieds, d'ouvertures 29 communiquant avec l'extérieur et, au voisinage de leurs têtes, d'embouts pour des tubulufes 30, 31, 32, 33 reliées à une tubuire centraie 3a, elle-même reliée à un compresseur 35.The side members are made in the form of tubes closed at the ends and on which suitable means such as collars are provided for fixing the turnbuckles and the feet. They are provided, on the veining of their feet, with openings 29 communicating with the outside. and, in the vicinity of their heads, nozzles for tubing 30, 31, 32, 33 connected to a central tube 3a, itself connected to a compressor 35.

Des crochets non représentés, fixés par exemple au voisinage des têtes des longerons, permettent d'émerger et d'immerger la cage ainsi constituée. A l'immersion, la tubulure 34 étant à l'air libre, les quatre longerons formant des ballasts s'emplissent d'eau par les ouvertures 29. A l'émersion, il suffit d'activer le compresseur 35 pour chasser l'eau présente dans les quatre longerons.Hooks not shown, fixed for example in the vicinity of the heads of the side members, make it possible to emerge and immerse the cage thus formed. Upon immersion, the tubing 34 being in the open air, the four longitudinal members forming ballasts fill with water through the openings 29. On emersion, it is sufficient to activate the compressor 35 to expel the water present in the four beams.

Les utilisateurs disposent ainsi d'une cage immergeable qui peut être de très grande dimension, puisque son voiume peut atteindre plusieurs dizaines de mêtres cubes, les longerons mesurant plusieurs mètres de longeur, avec un diamètre pouvant atteindre cinquante centimètres.Users thus have a submersible cage which can be very large, since its volume can reach several tens of cubic meters, the longitudinal members measuring several meters in length, with a diameter of up to fifty centimeters.

Cette cage est d'une légèreté exceptionnelle, d'une part pour ne comporter que quatre longerons, d'autre part parce que ces iongerons, ne travaillant qu'à la compression et exceptionnellement à la traction, peuvent entre relativement légers et surtout peuvent être réalisés en matériau plastique et enfin parce que les- longerons servent eux-mêmes de baliasts
On notera également la souplesse de l'ensemble constitue. par ces quatre longerons réunis uniquement par des tendeurs qui laissent une liberté de mouvement suffisante pour supporter les contraintes de déformation causées soit par la manutention, soit par la houle.
This cage is exceptionally light, on the one hand to have only four beams, on the other hand because these ioners, working only in compression and exceptionally in traction, can between relatively light and above all can be made of plastic and finally because the rails themselves serve as baliasts
Note also the flexibility of the assembly constitutes. by these four beams joined only by tensioners which allow sufficient freedom of movement to withstand the deformation stresses caused either by handling or by the swell.

Enfin, il ressort à l'évidence des explications qui precèdent qu'une telle cage est d'un prix de revient largement inférieur a celui des cages actuelles de volume comparable. Elle est en outre d'un montage et d'un démontage particulièrement rapides et aisés.Finally, it is evident from the foregoing explanations that such a cage has a cost price much lower than that of current cages of comparable volume. It is also particularly quick and easy to assemble and disassemble.

Il va de soi que le mode de réalisation faisant usage de quatre longerons qui a été décrit n'est pas limitatif. A titre d'exemple, il a été représente en figure 4 l'armature d'une cage semblable à trois longerons 36, 37, 38 dont les pieds 59, 42 41 sont au sommet d'un triangle équilatéral inférieur matérialisé par les tendeurs 42, 43 et 44, tandis que les têtes 45, 46, 47 sont les sommets, d'un triangle équilatéral supérieur de dimensions semblables matérialisé par les tendeurs 48, 49 et 50.It goes without saying that the embodiment making use of four beams which has been described is not limiting. For example, it has been shown in Figure 4 the frame of a cage similar to three beams 36, 37, 38 whose feet 59, 42 41 are at the top of a lower equilateral triangle materialized by the tensioners 42 , 43 and 44, while the heads 45, 46, 47 are the vertices, of an upper equilateral triangle of similar dimensions materialized by the tensioners 48, 49 and 50.

Le décalage angulaire entre la tête et le pied de chaque longeron est de l'ordre de 160 grâce à quoi le longeron 36 est chevauché, à environ un tiers de sa sa longueur, par le longeron 38 mais chevauche à son tour, avant d'atteindre la tête 45, le longeron e4. Trois -tendeurs ont été prévus en 51, 52 et 53 entre chaque pied tel que 39 et chaque tête telle que 47.The angular offset between the head and the foot of each spar is of the order of 160 thanks to which the spar 36 is overlapped, to about a third of its length, by the spar 38 but overlaps in turn, before reach head 45, the spar e4. Three tensioners have been provided at 51, 52 and 53 between each leg such as 39 and each head such as 47.

On réalise ainsi un volume à huit faces, à savoir les deux triangles équilatéraux et six triangles latéraux, trois ayant pour base un tendeur tel que 50 et le pied correspondant 39, les trois autres ayant pour base un tendeur tel que 43 et la tête correspondante 47. This produces an eight-sided volume, namely the two equilateral triangles and six lateral triangles, three having a tensioner as base as 50 and the corresponding foot 39, the other three having a tensioner as base as 43 and the corresponding head 47.
