Abstract

A structure (2) rising from the seabed carries a trapezoidal plate (1). The trapezoid tapers (5) in the direction of the tide and is entirely submerged. A smaller plate (6) overlaps the shorter side (4) of the trapezoidal plate and is attached to it by screwed connectors (7,8). These are adjusted so that the smaller plate is partly below and partly above the water line irrespective of the state of the tide at the chosen location. This arrangement harnesses the surface water movement. A water wheel (16) is supported on the smaller plate and caused to rotate by the tide running over it. A generator (23) is coupled to the wheel.

Description

L'objet de la présente invention est un dispositif destiné à créer artificiellement des vagues déferlantes au large et à exploiter leur énergie. The object of the present invention is a device intended to artificially create breaking waves offshore and to harness their energy.

Il résulte de la combinaison originale de moyens connus et de moyens nouveaux. It results from the original combination of known means and new means.

Dans l'état actuel de la technique il n'existe pas à notre connaissance de dispositif dont l'objet soit de créer au large des vagues déferlantes. In the current state of the art, to our knowledge, there is no device whose object is to create off the breaking waves.

On connait toutefois des systemes constitués par des éléments de digues en béton, juxtaposés, ayant la forme de tremplins triangulaires à profil curviligne se terminant en entonnoir et dont le but est d'obliger les vagues s'engouffrant vers leur partie la plus large, de s'élever dans la partie étroite de ces entonnoirs jusqu'à un réservoir ou elles sont recueillies et dont la différence de niveau avec le niveau moyen est theoriquement exploitable par une turbine. However, systems are known which are made up of juxtaposed concrete dam elements, in the form of triangular springboards with a curvilinear profile ending in a funnel, the purpose of which is to force the waves rushing towards their widest part, rise in the narrow part of these funnels to a reservoir where they are collected and whose difference in level with the average level is theoretically exploitable by a turbine.

On sait que l'énergie de la houle se matérialise par un mouvement circulaire des molécules d'eau, décroissant exponentiellement avec la profondeur, et que ce mouvement ne se transforme en mouvement rectiligne, avec création de déferlantes dans le sens de la progression de la houle, que lorsque cette dernière rencontre un haut fond. We know that the energy of the swell is materialized by a circular movement of the water molecules, decreasing exponentially with depth, and that this movement does not transform into rectilinear movement, with the creation of breaking waves in the direction of the progression of the swell, only when the latter meets a high bottom.

Dans la presente invention on se propose de créer au large un haut fond artificiel en plan incliné provoquant la transformation de la houle en vagues deferlantes régulières, et d'exploiter l'énergie de ces vagues. In the present invention, it is proposed to create offshore an artificial bottom in an inclined plane causing the transformation of the swell into regular breaking waves, and to harness the energy of these waves.

Dans un type de réalisation de l'invention schématiquement illustré par la figure I ce haut fond est constitué par une plaque principale trape zoîdale (1) supportée par une structure fixe (2) de telle sorte que sa grande base (3) soit moins élevée que sa petite base (4). In one type of embodiment of the invention schematically illustrated in FIG. 1, this high bottom is constituted by a main zoidal trap plate (1) supported by a fixed structure (2) so that its large base (3) is lower than its small base (4).

La perpendiculaire médiane à ces bases est dirigée suivant le sens de la houle dominante. The median perpendicular to these bases is directed in the direction of the dominant swell.

Cette plaque trapezoîdale est totalement immergée et ses côtés forment un angle (5) dans lequel se situe la direction de la majorité des houles constatées sur le site.  This trapezoidal plate is completely submerged and its sides form an angle (5) in which the direction of the majority of the swells observed on the site is located.

A ce niveau de sa petite base (4) qui est la plus élevée, elle est recouverte par une deuxième plaque (6) qui peut glisser sur la plaque (1) grâce à deux vérins (7) et (8) connus attachés d'un côté en (9) et (10) a la plaque (6) et de l'autre côté en (11) et (12) à la plaque (1). At this level of its small base (4) which is the highest, it is covered by a second plate (6) which can slide on the plate (1) thanks to two known jacks (7) and (8) attached to one side at (9) and (10) has the plate (6) and on the other side at (11) and (12) the plate (1).

Le bord supérieur (13) de cette plaque (6) émerge du niveau moyen de l'eau alors que son bord inferieur (14) est situé en dessous de ce niveau moyen. Par le jeu des verins (7) et (8) la plaque (6) peut conserver la même émergence quelle que soit la marée sur le site. The upper edge (13) of this plate (6) emerges from the average level of the water while its lower edge (14) is located below this average level. By the play of jacks (7) and (8) the plate (6) can keep the same emergence whatever the tide on the site.

Sur cette plaque (6) est installé un système récupérateur d'énergie (15) qui peut être par exemple un ensemble de roues a aubes telles que (16) montées sur le même axe (17) lequel est soutenu par deux paliers extrêmes (18) et (19) et par plusieurs paliers intermédiaires (20) et (21). On this plate (6) is installed an energy recovery system (15) which can be for example a set of impellers such as (16) mounted on the same axis (17) which is supported by two end bearings (18 ) and (19) and by several intermediate bearings (20) and (21).

Le diamètre de ces roues à aubes est uniforme et leur axe commun (17) est situé à une hauteur superieure à celle des plus hautes vagues déferlantes produites par la houle maximum. The diameter of these impellers is uniform and their common axis (17) is located at a height greater than that of the highest breaking waves produced by the maximum swell.

Les aubes des roues sont presque tangentes en (22) à la plaque (6). The blades of the wheels are almost tangent at (22) to the plate (6).

Frappées par le déferlement de la houle elles entraînent en rotation l'axe (17) qui fait à son tour tourner un alternateur (23) qui peut être remplacé par une pompe hydraulique ou tout-autre système de production d'énergie connu. Cette énergie peut être transportée au rivage par un cable (24) ou par une tuyauterie sous-marine. Struck by the surge of the swell they cause the axis (17) to rotate, which in turn turns an alternator (23) which can be replaced by a hydraulic pump or any other known energy production system. This energy can be transported to shore by a cable (24) or by underwater piping.

Après déferlement la vague s'écoule par dessus le bord (13) de la plaque (6) qui joue le rôle de système anti retour, toute quantité d'eau qui aurait tendance à revenir en arrière etant conduite à glisser sous la plaque (6). After breaking the wave flows over the edge (13) of the plate (6) which acts as a non-return system, any amount of water which would tend to go back being driven to slide under the plate (6 ).

Dans un autre type de réalisation (fig 2 Planche II) la plaque (1) au lieu d'être trapezoldale est seulement rectangulaire.  In another type of embodiment (fig 2 Plate II) the plate (1) instead of being trapezoidal is only rectangular.

L'exploitation de l'énergie des houles de différentes directions est alors obtenue en disposant plusieurs plaques sur le site, orientées chacunes dans un des divers sens préférentiels de la houle. The exploitation of the energy of swells from different directions is then obtained by placing several plates on the site, each oriented in one of the various preferential directions of the swell.

Le dispositif proposé par l'invention est utilisable dans la récupération de l'énergie de la houle et peut servir à alimenter soit des agglomerations sur le rivage soit des installations sur plateformes en mer, telles des champs pétroliers ou des usines flottantes.  The device proposed by the invention is usable in recovering the energy of the swell and can be used to supply either agglomerations on the shore or installations on offshore platforms, such as oil fields or floating factories.
