Ce dispositif permet de convertir l’énergie de la houle et des vagues sous forme d’énergie mécanique, hydraulique et électrique .This device allows the energy of the swell and waves to be converted into mechanical, hydraulic and electrical energy.
- Caractéristiques :- Features :
Le dispositif présenté dans ce brevet comporte trois ensembles :The device presented in this patent comprises three sets:
-un flotteur semi-immergé (1) comportant des ballasts (6) , un compartiment énergie et deux compartiments de transmission mécanique (7). Des câble immergés (12) (13) et (14) relient le flotteur à la terre pour l’énergie, les contrôles et les commandes. - A semi-submerged float (1) comprising ballasts (6), an energy compartment and two mechanical transmission compartments (7). Submerged cables (12) (13) and (14) connect the float to ground for power, controls and commands.
-deux bras orientables (2) fixés sur un massif support (3) situé au fond de la mer. - two adjustable arms (2) fixed on a solid support (3) located at the bottom of the sea.
- deux chaînes (4) reliant les bras orientables au flotteur en passant par les pignons (9) (10) (11) des compartiments transmission. A la suite des pignons (10) ces chaînes descendent verticalement et sont mises en tension par deux masses-contrepoids (17).- two chains (4) connecting the adjustable arms to the float via the sprockets (9) (10) (11) of the transmission compartments. Following the sprockets (10) these chains descend vertically and are tensioned by two mass-counterweights (17).
- Fonctionnement :- Functioning :
Sous l’effet de la houle, le flotteur est soumis à des mouvements verticaux ; dans le sens de la montée les chaînes de liaison font tourner les pignons moteurs situés dans les compartiments transmission et, dans le sens de la descente ces mêmes chaînes lestées à leurs extrémités libres par les masses-contrepoids (17) entraînent la rotation des pignons moteurs.Under the effect of the swell, the float is subjected to vertical movements; in the up direction the connecting chains rotate the motor sprockets located in the transmission compartments and, in the down direction, these same chains weighted at their free ends by the masses-counterweights (17) cause the rotation of the motor sprockets .
Adaptation de la puissance du houlomoteur en fonction de la hauteur de la houle.Adaptation of the power of the wave motor according to the height of the swell.
Le problème qui se pose est le suivant : l’énergie potentielle, composante verticale de la houle, que peut récupérer le flotteur à un instant donné, est proportionnelle à la période de la houle et au carré de sa hauteur ; par exemple, pour une hauteur de houle de 2,5 m et une période de 9 secondes, la puissance de la houle est de l’ordre de 14 kW par mètre de crête de vague, et pour une hauteur de houle de 4,5 m elle atteint 55 kW par mètre de crête de vague. En fonction des données statistiques de la houle d’un lieu où l’on veut implanter le dispositif flotteur, il convient de choisir au mieux les valeurs des masses-contrepoids (17) qui actionnent les équipements mécaniques, ce qui conduit inévitablement à déterminer un pourcentage de récupération de l’énergie disponible, en fonction des hauteurs de la houle. Ainsi, si l’on choisit de privilégier les faibles hauteurs de houle, par exemple de 1 à 2,5 mètres, il ne sera pas possible d’augmenter sensiblement la récupération d’énergie pour des houles plus hautes, pourtant bien plus énergétiques ; et réciproquement, si l’on choisit de privilégier les houles plus hautes, avec des masse plus importantes pour les contrepoids (17), le bon rendement énergétique ne sera plus assuré pour les petites hauteurs de houle. La solution idéale consiste donc à faire varier la masse des contrepoids en fonction de la hauteur de la houle.The problem that arises is the following: the potential energy, the vertical component of the swell, that can recovering the float at a given instant is proportional to the period of the swell and to the square of its height; for example, for a wave height of 2.5 m and a wave period of 9 seconds, the wave power is of the order of 14 kW per meter of wave crest, and for a wave height of 4.5 m it reaches 55 kW per meter of wave crest. Depending on the statistical data of the swell of a place where the float device is to be installed, it is advisable to best choose the values of the mass-counterweights (17) which actuate the mechanical equipment, which inevitably leads to determining a percentage of available energy recovery, depending on the height of the swell. Thus, if we choose to favor low wave heights, for example from 1 to 2.5 meters, it will not be possible to significantly increase energy recovery for higher swells, which are nevertheless much more energetic; and conversely, if we choose to favor higher swells, with greater masses for the counterweights (17), good energy efficiency will no longer be guaranteed for low swell heights. The ideal solution therefore consists in varying the mass of the counterweights according to the height of the swell.
La présente invention consiste à rajouter à la partie inférieure dechaque masse contrepoids (17)un câble (18) ou une chaîne descendant verticalement jusqu’au fond de la mer et dont une deuxième partie s’étale au fond, sur une dalle (20) ; c’est dans cette deuxième partie que sont attachées deux ou trois masses supplémentaires (19), à des distances bien définies les unes des autres, et dont les effets de contrepoids se rajoutent par paliers à la masse (17) au-delà de certaines hauteurs de houle déterminées . Lorsque la hauteur de houle diminue, les masses (19) reposent à nouveau au fond, et seule la masse (17) reste active. Pour éviter tout ballotement des masses (19) en fonctionnement, celle située la plus basse est reliée par chaîne et ressort au massif support (3) .The present invention consists in adding to the lower part of each counterweight mass (17) a cable (18) or a chain descending vertically to the bottom of the sea and of which a second part is spread out at the bottom, on a slab (20 ); it is in this second part that two or three additional masses (19) are attached, at well-defined distances from each other, and whose counterweight effects are added in stages to the mass (17) beyond certain wave heights determined . When the wave height decreases, the masses (19) rest again on the bottom, and only the mass (17) remains active. To avoid any sloshing of the masses (19) in operation, the one located lowest is connected by chain and spring to the solid support (3).
En variante , dans le cas de deux masses supplémentaires (19/1) et (19/2) , ces masses sont montées sur une tige verticale (21) fixée à la masse inférieure (19/2) et traversant la masse supérieure (19/1) . En fin de montée de la masse supérieure, une butée (22) permet alors de soulever la masse inférieure (19/2) . Alternatively , in the case of two additional masses (19/1) and (19/2), these masses are mounted on a vertical rod (21) fixed to the lower mass (19/2) and crossing the upper mass (19 /1) . At the end of the rise of the upper mass, a stop (22) then makes it possible to raise the lower mass (19/2).

Ce dispositif est particulièrement bien adapté aux zones océaniques où les valeurs moyennes des marnage sont faibles, inférieures à 1 m ; elles sont nombreuses autour des océans et des iles, par exemple en Afrique du Sud, à La Réunion, à Hawaii, où les fortes houles sont fréquentes. Il présente également l’avantage de se situer proche de la côte pour toutes les liaisons et raccordements. De tels dispositifs peuvent être installés en nombre, sans nuire à l’environnement côtier et marin ; de plus, ils contribuent à la protection des rivages.This device is particularly well suited to oceanic areas where the mean tidal range values are low, less than 1 m; they are numerous around oceans and islands, for example in South Africa, Reunion, Hawaii, where strong swells are frequent. It also has the advantage of being close to the coast for all connections and connections. Such devices can be installed in large numbers, without harming the coastal and marine environment; moreover, they contribute to the protection of shorelines.
