Description

Hydrolienne souple gonflableInflatable flexible water

Elle peut être construite en deux versions, l'une destinée à l'exploitation de l'énergie de la houle, l'autre à l'exploitation de l'énergie des courants marins ou autres. Les principes techniques généraux sont analogues à ceux que nous avons exposés dans notre demande de brevet INPI N 06 04239 concernant une éolienne flottante autoporteuse.  It can be built in two versions, one for the exploitation of the energy of the swell, the other for the exploitation of the energy of the marine currents or others. The general technical principles are similar to those which we exposed in our patent application INPI N 06 04239 concerning a self-supporting floating wind turbine.

Caractéristiques communes (fig. 1) Elles se retrouvent tant dans le convertisseur de houle que dans l'hydrolienne destinée à l'exploitation des courants marins. Le dispositif est formé d'un ballon sphérique, ovale ou cylindrique' gonflable, compartimenté intérieurement en deux types de compartiments (la fig. 1 montre la coupe équatoriale du système): 1/Cinq à six compartiments externes (A), en forme de croissants ou de cylindres, disposés symétriquement autour de l'axe central de rotation et se joignant par leurs pointes aux extrémités de cet axe, et gonflés d'air. 2/Un compartiment (B) gonflé à l'eau sous pression et délimité extérieurement par le les éléments (A) d'une part, et d'autre part par des toiles (ti) tangentes alternativement de manière interne et externe aux éléments (A). Le compartiment (B) est de plus cloisonné par des toiles (t2) disposées radialement et destinées à solidariser la rotation de l'eau contenue en (B) avec la rotation de l'ensemble du ballon. Le choix de l'eau plutôt que de l'air pour le remplissage de B permet de ,Lo régulariser la rotation en augmentant l'inertie du système. 3/ Il se rajoute un ou deux2 compartiments annexes (C), gonflés à l'air, et servant à comprimer l'eau du compartiment (B) afin de maintenir sa pression à une valeur supérieure à celle de l'eau ambiante, et suffisante pour assurer, conjointement avec les éléments (A) gonflés d'air, la rigidité du système. La présence d'éléments (A) et (C) gonflés d'air 4Ç rend l'ensemble du ballon autoflotteur. L'asymétrie due à la présence de toiles (t1) tangentes alternativement de manière interne et externe aux éléments (A) permettra au dispositif soit de tourner dans un courant marin sous l'effet de la traînée différentielle induite (version hydrolienne de courant) soit de suivre le mouvement de rotation de la houle (version convertisseur % de houle), les éléments (A) agissant sur le mode de pales de turbine, et l'ensemble du ballon formant rotor.  Common characteristics (Figure 1) They are found in both the wave converter and the tidal turbine for the exploitation of marine currents. The device consists of an inflatable spherical, oval or cylindrical balloon internally divided into two types of compartments (Fig. 1 shows the equatorial section of the system): 1 / Five to six external compartments (A), shaped like croissants or cylinders, arranged symmetrically about the central axis of rotation and joining by their ends at the ends of this axis, and inflated with air. 2 / A compartment (B) inflated with pressurized water and delimited externally by the elements (A) on the one hand, and on the other hand by canvases (ti) tangent alternately internally and externally to the elements ( AT). The compartment (B) is further partitioned by webs (t2) arranged radially and intended to secure the rotation of the water contained in (B) with the rotation of the entire balloon. The choice of water rather than air for the filling of B makes it possible to regulate the rotation by increasing the inertia of the system. 3 / There is added one or two additional compartments (C), inflated with air, and used to compress the water compartment (B) to maintain its pressure to a value greater than that of the ambient water, and sufficient to ensure, together with the elements (A) inflated with air, the rigidity of the system. The presence of elements (A) and (C) inflated with air 4Ç makes the whole balloon autoflotteur. The asymmetry due to the presence of alternately tangential webs (t1) internally and externally to the elements (A) will allow the device to either turn in a marine current under the effect of the induced differential drag (tidal current version) or to follow the rotational movement of the swell (wave converter version), the elements (A) acting on the turbine blade mode, and the entire rotor flask.

Convertisseur de houle (fig.2,3 et 4) Le ballon-rotor présentera une forme fortement allongée cylindrique (en rouleau) sur sa longueur, et arrondie aux extrémités auxquelles se joignent les éléments A et W auxquelles se trouvent les compartiments (C) (fig. 2 et 3). Les proportions sont tracées à titre indicatif, le diamètre du cylindre devant être de l'ordre de grandeur du creux de la houle moyenne du lieu). Les ballons seront disposés horizontalement à ras de l'eau, quasi totalement immergés, enchaînés les uns aux autres face à la houle. Les éléments de jonction G (fig. 3) -qui forment les seuls éléments rigides du yodispositif- sont reliés aux ballons par un faisceau de câbles et contiennent chacun deux générateurs électriques dont le rotor sera actionné par un des rouleaux. De Ovale ou sphérique dans le cas de l'hydrolienne de courant, cylindrique à bouts arrondis dans le cas du convertisseur de houle. 2 Deux positionnés aux extrémités dans la cas du convertisseur de houle (fig. 2 et 3) et un, placé en position sommitale dans le cas de l'hydrolienne de courant (fig. 5) plus, ces éléments de jonction porteront suspendus, par l'intermédiaire de leviers, des lests de béton destinés à maintenir les ballons en situation de semi immersion et à fournir les moments résistants permettant l'immobilisation des stators des générateurs (fig. 3) .  Wave converter (fig. 2,3 and 4) The rotor-balloon will have a strongly elongated cylindrical shape (in roll) along its length, and rounded at the ends to which the elements A and W are joined with compartments (C) (Figures 2 and 3). The proportions are given as an indication, the diameter of the cylinder to be of the order of magnitude of the hollow of the average swell of the place). The balloons will be horizontally flush with the water, almost completely immersed, chained to each other in front of the swell. The joining elements G (FIG 3) - which form the only rigid elements of the yodispositif- are connected to the balloons by a bundle of cables and each contain two electric generators whose rotor will be actuated by one of the rollers. Oval or spherical in the case of the current turbine, cylindrical with rounded ends in the case of the wave converter. 2 Two positions at the ends in the case of the wave converter (Figures 2 and 3) and one, placed in the top position in the case of the current turbine (Figure 5) plus, these connecting elements will be suspended by using levers, concrete weights to hold the balloons in a semi-immersion situation and to provide the resistant moments allowing immobilization of the stators of the generators (FIG 3).

Les enchaînements de ballons, placés face à la houle, seront de place en place ancrés au fond, permettant le maintien en position de l'ensemble du dispositif ainsi que l'évacuation du courant électrique produit vers la rive. II en résultera une disposition d'ensemble telle qu'elle est représentée sur la figure 4. (Sur cette figure, seuls les rouleaux gonflables sont représentés et non les éléments (G)).  The sequences of balloons, placed in front of the swell, will be from place to place anchored to the bottom, allowing the maintenance of the entire position of the device as well as the evacuation of the electric current produced towards the shore. This will result in an overall arrangement as shown in Figure 4. (In this figure, only the inflatable rollers are shown and not the elements (G)).

le Hydrolienne de courant (fiq.5) Elle sera formée d'au moins deux ballons tels que décrits sous le titre caractéristiques communes , positionnés à axe vertical (ou quasi vertical du fait de la déviation due à la pression du courant). L'ancrage se fera au fond. Deux ballons superposés tourneront en sens inverse, entraînant au moyen d'un dispositif iÇ de câbles (fig. 5) le rotor et le contre rotor d'un générateur logé dans une nacelle G placée entre les deux ballons. (Nous reprenons ici un dispositif analogue à celui proposé pour une éolienne flottante d'altitude dans notre demande de brevet INPI N 06 04239). Les ballons (contrairement au cas du convertisseur de houle) pourront présenter une section équatoriale très large (forme sphérique3 ou en citrouille ) % destinée à capter une largeur maximale de courant. Les éléments (B) verront, depuis la section équatoriale jusqu'au extrémités, leur diamètre se réduire proportionnellement à celui du ballon lui-même, prenant ainsi une forme en croissant . L'élément (C) occupera, dans chaque ballon, une position sommitale. Une variante du système pourra être constituée d'un seul ballon lequel entraîne au $5 moyen de câbles le rotor du générateur, le stator de celui-ci étant immobilisé par rapport au fond de l'eau par fixation ou amarrage direct.  the current hydrolienne (fiq.5) It will be formed of at least two balloons as described under the title common characteristics, positioned vertical (or almost vertical because of the deviation due to the pressure of the current). Anchoring will be done at the bottom. Two superposed balloons will rotate in the opposite direction, driving by means of a cable device (FIG 5) the rotor and the counter-rotor of a generator housed in a nacelle G placed between the two balloons. (Here we resume a similar device to that proposed for a vertical wind turbine in our patent application INPI N 06 04239). The balloons (contrary to the case of the wave converter) may have a very wide equatorial section (spherical shape3 or pumpkin)% intended to capture a maximum current width. The elements (B) will see, from the equatorial section to the ends, their diameter being reduced proportionally to that of the balloon itself, thus taking a crescent shape. The element (C) will occupy, in each balloon, a summit position. A variant of the system may consist of a single balloon which drives the rotor of the generator by means of cables, the stator of which is immobilized relative to the bottom of the water by direct attachment or docking.
