Abstract

The wave power energy converter is mounted on a vertical axis supported by a vertical column. The vertical rotating shaft carried in bearings in the column, has radial arms fixed perpendicular to the shaft. The arms are at equal angles in the horizontal plane. Each arm has a rigid rectangular flap suspended from it by pivots. Below each arm, and fixed to the rotating shaft, a radial projection prevents the flap moving past the vertical when wave pressure is applied in one sense, while not impeding the angular displacement of the flap in the opposite sense. A wave causes a net torque on the shaft because one flap is held square on by the projection while the diametrically opposite flap in deflected upwards towards the horizontal. The ebb and flow of a wave causes first one side of the converter, then the other, to be effective. The rotating shaft is gear coupled to an electric generator mounted on a fixed vertical rod attached to the support column.

Description

Collecteur à double effet du mouvement des ondes
On sait que les ondes de la mer sont soumises à un continuel flux et reflux.Double effect collector of wave movement
We know that the waves of the sea are subject to a continuous ebb and flow.

L'inversion continuelle de leur sens d'avancement crée donc des problèmes considérables d'exploitation de l'é- nergie cinétique.The continual reversal of their direction of advancement therefore creates considerable problems of exploitation of kinetic energy.

La présente invention résout ces problèmes avec simpli- cité, ainsi qu'il sera démontré ci-aprés.The present invention solves these problems with simplicity, as will be demonstrated below.

D'après cette invention, une couronne mobile est prévue avec un axe de rotation vertical à pales radiales arti- culées sur des rayons substantiellement horizontaux.According to this invention, a mobile crown is provided with a vertical axis of rotation with radial blades articulated on substantially horizontal spokes.

Elles sont articulées en haut, la force de gravité tendant donc à Baire assumer aux pales une position de repos verticale.They are articulated at the top, the force of gravity therefore tending to Baire assume the blades a vertical rest position.

La rotation de chacune des pales sur son articulation, sous la poussée des ondes, est bloquée dans un des deux sens (le mêe pour toutes les pales), quand la position verticale, ou en tous cas la position d'incidence maximale des ondes, est atteinte, par des éléments d' arrdt solidaires à la couronne mobile, de façon que, quand les ondes avancent dans une direction, les pales qui, d'instant en instant viennent se situer d'un côté de l'axe de rotation de la couronne mobile, reçoivent en plein la poussée des ondes, alors.que les pales se trouvant du côté opposé, tournant librement sur leur articulation, se disposent de manière à offrir aux ondes une incidence minimale.The rotation of each of the blades on its articulation, under the push of the waves, is blocked in one of two directions (the same for all the blades), when the vertical position, or in any case the position of maximum incidence of the waves, is reached, by stop elements integral with the movable crown, so that, when the waves advance in one direction, the blades which, from moment to moment come to lie on one side of the axis of rotation of the mobile crown, receive full wave thrust, while the blades being on the opposite side, freely rotating on their articulation, are arranged so as to offer the waves a minimal incidence.

Quand le sens dZavancement des ondes est inversé, les pales qui viennent se situer dans la partie précédemment soumise en plein à la poussée des ondes se disposent dans la position d'incidence minimale, et les pales situées du c8té opposé reçoivent la poussée des ondes en plein. Ceci avec un effet de rotation toujours dans le même sens de la couronne mobile, indépendemment du sens d'avancement des ondes dans leur flux et reflux.When the direction of advance of the waves is reversed, the blades which come to be situated in the part previously subjected in full to the thrust of the waves are arranged in the position of minimum incidence, and the blades located on the opposite side receive the thrust of the waves in full. This with an effect of rotation always in the same direction of the mobile crown, independently of the direction of advance of the waves in their ebb and flow.

Dans une forme préférée de réalisation, les pales sont au nombre de quatre, rectangulaires et disposées à 900 par rapport à l'arbre de la couronne mobile, afin daévi- ter toute interférence entre les pales durant leurs soulèvements prgressifs. In a preferred embodiment, the blades are four in number, rectangular and arranged at 900 relative to the shaft of the movable crown, in order to avoid any interference between the blades during their progressive lifting.

Les caractéristiques et les buts de cette invention seront rendus encore plus clairs par les exemples de réalisation illustrés par les figures schématiques.The characteristics and aims of this invention will be made even clearer by the exemplary embodiments illustrated by the schematic figures.

Fig. 5) Détail
Fig. 1), La couronne mobile 10) est libre de tourner autour ae l'arbre fixe 11), sur lequel est monté le gé- nérateur électrique 12). Les pales 14), 15), 16), 17) sont suspendues aux bras 13).Fig. 5) Detail
Fig. 1), the movable crown 10) is free to rotate around the fixed shaft 11), on which the electric generator 12) is mounted. The blades 14), 15), 16), 17) are suspended from the arms 13).

Les dents 18) solidaires à la couronne mobile interdisent aux pales de tourner autour des bras dans l'un des deux sens outre la verticale L'arbre fixe est so- lidaire à la colonne 19) ancrée au fond de la mer. Le courant électrique engendré est convoyé vers la rive par les câbles 20). The teeth 18) integral with the movable crown prevent the blades from turning around the arms in one of the two directions in addition to the vertical. The fixed shaft is secured to the column 19) anchored to the bottom of the sea. The electric current generated is conveyed to the shore by the cables 20).

Quand les ondes avancent dans le sens des flêches, les pales se trouvant dans la position de la pale 14), cest-à-dire à droite de la figure, reçoivent la poussée des ondes en plein tandis que les pales qui se trouvent dans la position de la pale 16), c'est-à-dire à gauche, se soulèvent sous la poussée des ondes, offrant à celles-ci peu de résistance.When the waves advance in the direction of the arrows, the blades being in the position of the blade 14), that is to say to the right of the figure, receive the thrust of the waves in full while the blades which are in the position of the blade 16), that is to say on the left, are raised under the push of the waves, offering them little resistance.

Quand le mouvement des ondes s'inverser, les pales de droite se soulèveront et celles de gauches recevront en plein la poussée des ondes, La couronne mobile tourne- ra donc toujours dans le mEme sens indépendemment du sens des ondes.When the movement of the waves is reversed, the blades on the right will lift and those on the left will receive the full thrust of the waves. The movable crown will therefore always rotate in the same direction regardless of the direction of the waves.

La simplicité de l'installation et ses avantages conside'- rables sur le rendement et la puissance globale sont évidents.The simplicity of the installation and its considerable advantages in terms of efficiency and overall power are obvious.

Fig.2). lBlle illustre une couronne mobile 21), presque identique-à celle de la Fig. 1), présentant la variante des masses 22 ) qui équilibrent partiellement le poids des pales en alliage léger comme la 23).  Fig. 2). lBlle illustrates a movable crown 21), almost identical to that of FIG. 1), presenting the variant of the masses 22) which partially balance the weight of the light alloy blades such as 23).

La différence entre les poids des masses et celui des pales suffit à contraindre les panneaux en position ver ticale tout en s'opposant' en mesure minimale au soulèvement déjà décrit'des pales comme la 24) et donc au mouve ment de la couronne mobile.The difference between the weights of the masses and that of the blades is sufficient to constrain the panels in a vertical position while opposing 'as a minimum measure the lifting already described (blades like 24) and therefore the movement of the movable crown.

Dans la variante de la Fig. 3, la couronne mobile 25) est composée de deux séries 26) et 27) de pales superposées comme les 28) et 29), chacune ayant une hauteur d'à peu près la moitié de celles des fig. 1) et 2). I1 est ainsi possible de prévoir un plus grand nombre de pales avec un effet plus continu de poussée des ondes.In the variant of FIG. 3, the movable crown 25) is composed of two series 26) and 27) of superimposed blades like 28) and 29), each having a height of about half that of FIGS. 1 and 2). It is thus possible to provide a larger number of blades with a more continuous effect of wave pushing.

La variante de la Fig. 4) consiste dans l'adoption sur la couronne mobile 38), en place de chaque pale, d'un couple 30) de pales 31) et 32), chacune d'elle articulée sur les bras respectivement comme à 33) et 34).The variant of FIG. 4) consists in the adoption on the movable crown 38), in place of each blade, of a couple 30) of blades 31) and 32), each of them articulated on the arms respectively as in 33) and 34) .

Les couples d'engrenages 35) et 36), solidaires aux pa les,détermnent pour chaque pale de chaque couple un mouvement inverse à celui'de l'autre pale et donc leur équilibrage réciproque.The pairs of gears 35) and 36), integral with the blades, determine for each blade of each couple a movement opposite to that of the other blade and therefore their reciprocal balancing.

Le développement de la denture des engrenages, ainsi que le montre clairement la Fig. 5), est tel qu'il interdit aux pales de se renverser au-delà de la position verticale et aussi d'atteindre une position horizontale.The development of the teeth of the gears, as clearly shown in FIG. 5), is such that it prevents the blades from overturning beyond the vertical position and also from reaching a horizontal position.

Sous la poussée des ondes, les pales de droite tendent à s'ouvrir et celles de gauche à se fermer comme le couple 37).Under the pressure of the waves, the right blades tend to open and those on the left to close like the couple 37).

Quand les ondes changent de direction, les pales de ce dernier couple sont contraintes à s'ouvrir et à se disposer en position verticale, recevant en plein le choc des ondes.When the waves change direction, the blades of this last couple are forced to open and to be arranged in vertical position, receiving in full the shock of the waves.

Le rendement de l'installation s'avantage de l'équili- brage et de la disposition symétrique deS pales de chaque couple. The efficiency of the installation benefits from the balancing and the symmetrical arrangement of the blades of each pair.
