  • a fluid communication located below the upper surface of the support connects said deep external aquatic region to an opening opening in said volume of collection of the support.

On évite ainsi, au moins en majeure partie, qu'il y ait du ressac dans la région aquatique interne, puisque l'eau en fin de parcours des vagues quitte la région aquatique interne en tombant dans le volume de recueil du support d'où elle est évacuée sans passer par la région aquatique interne puisque la communication fluidique est située sous la surface supérieure du support.This avoids, at least for the most part, that there is surf in the internal aquatic region, since the water at the end of the course of the waves leaves the internal aquatic region by falling into the volume of collection of the support from where it is evacuated without passing through the internal aquatic region since the fluidic communication is located under the upper surface of the support.

La région aquatique externe supérieure n'est pas non plus perturbée, ou alors très peu, puisque c'est la région aquatique externe profonde qui est en communication avec le volume de recueil du support.The upper external aquatic region is also not disturbed, or very little, since it is the deep external aquatic region that is in communication with the volume of collection of the support.

La région aquatique interne, et d'ailleurs la région aquatique externe supérieure, n'étant ainsi pas perturbées par le ressac, ou à tout le moins très peu perturbées, il est possible d'avoir un délai très court entre deux vagues successives.The internal aquatic region, and moreover the upper external aquatic region, is thus not disturbed by the surf, or at least very little disturbed, it is possible to have a very short delay between two successive waves.

L'installation selon l'invention présente ainsi de bonnes capacités d'utilisation.The installation according to the invention thus has good use capacities.

Au surplus, le support est relativement peu sollicité mécaniquement par les vagues puisque l'eau est guidée vers le volume de recueil à partir duquel elle rejoint naturellement la région aquatique externe profonde, du simple fait de la communication fluidique.In addition, the support is relatively little mechanically solicited by the waves since the water is guided to the collection volume from which it naturally joins the deep external aquatic region, simply by fluid communication.

L'installation selon l'invention présente ainsi de bonnes performances en matière de longévité.The installation according to the invention thus has good performance in terms of longevity.

On notera que, de même que dans l'installation du mode de réalisation illustré sur les figures 8 et 9 du brevet américain 3,913,332, dans l'installation selon l'invention les vagues ne déferlent que d'un seul côté du générateur de vagues.It should be noted that, as in the installation of the embodiment illustrated in FIGS. 8 and 9 of US Pat. No. 3,913,332, in the installation according to the invention the waves only break on one side of the wave generator.

En effet, dans l'installation selon l'invention, les vagues déferlent uniquement du côté du support. Aucune vague ne peut déferler de l'autre côté, qui est occupé uniquement par la région aquatique externe profonde et par la région aquatique externe supérieure qui sont contigües horizontalement.Indeed, in the installation according to the invention, the waves break only on the side of the support. No wave can break on the other side, which is occupied solely by the deep outer aquatic region and the upper outer aquatic region which are contiguous horizontally.

On notera par ailleurs qu'il est bien entendu que la subdivision du milieu aquatique en différentes régions aquatiques est uniquement basée sur la localisation des régions en question par rapport au support, c'est-à-dire que les régions aquatiques désignent des lieux où se trouve de l'eau et non des volumes d'eau isolés.It should also be noted that it is understood that the subdivision of the aquatic environment into different aquatic regions is based solely on the location of the regions in question relative to the support, that is to say that the aquatic regions designate places where there is water and not isolated water volumes.

En particulier, il n'y a pas de parois étanches aux liquides isolant les différentes régions aquatiques les unes des autres. Au contraire, l'eau du milieu aquatique circule entre les différentes régions aquatiques. Ainsi, quand le générateur de vagues est au repos, l'ensemble du milieu aquatique a le même niveau de surface. Par exemple, quand le générateur de vagues est au repos, le niveau de la surface de la région aquatique interne est identique au niveau de la surface de la région aquatique externe supérieure.In particular, there are no liquid-tight walls isolating the different aquatic areas from each other. On the contrary, the water of the aquatic environment circulates between the different aquatic regions. Thus, when the wave generator is at rest, the entire aquatic environment has the same level of surface. For example, when the wave generator is at rest, the level of the surface of the internal water region is the same as the surface level of the upper external aquatic region.

Selon des caractéristiques avantageuses, ledit support est une plateforme ; ledit milieu aquatique comporte en-dessous de la plateforme une région, appelée ci-après région aquatique sous-jacente, la région aquatique externe profonde et la région aquatique sous-jacente étant contigües verticalement ; et ladite ouverture débouchant dans le volume de recueil du support débouche dans la région aquatique sous-jacente, ladite communication fluidique située sous la surface supérieure du support étant mise en oeuvre par la région aquatique sous-jacente.According to advantageous features, said support is a platform; said aquatic medium comprises below the platform a region, hereinafter referred to as the underlying aquatic region, the deep external aquatic region and the underlying aquatic region being contiguous vertically; and said opening opening into the media collection volume opens into the underlying aquatic region, said fluid communication located below the upper surface of the support being carried out by the underlying aquatic region.

C'est donc au-dessus de la plateforme que l'eau est en mouvement lorsque le générateur de vagues est en service, et non au-dessus du fond du milieu aquatique comme c'est le cas dans l'installation décrite par le brevet américain 3,913,332.It is therefore above the platform that the water is in motion when the wave generator is in use, and not above the bottom of the aquatic environment as is the case in the installation described by the patent. American 3,913,332.

On évite ainsi de mettre en suspension les sédiments, alluvions et analogues généralement présents sur le fond d'un milieu aquatique.This avoids the suspension of sediments, alluvium and the like generally present on the bottom of an aquatic environment.

Plus généralement, les perturbations apportées par l'installation à la région aquatique sous-jacente sont minimes puisqu'il s'agit simplement d'une circulation d'eau pour maintenir constant le niveau du volume de recueil de la plateforme, qui s'effectue de façon naturelle suivant le principe des vases communicants.More generally, the disturbances brought by the installation to the underlying aquatic region are minimal since it is simply a circulation of water to keep constant the level of the volume of collection of the platform, which is done naturally according to the principle of communicating vessels.

L'invention vise, sous un deuxième aspect, à fournir une installation qui minimise les perturbations apportées au milieu aquatique.The invention aims, in a second aspect, to provide an installation that minimizes disturbances to the aquatic environment.

American 3,913,332.

L'exposé de l'invention sera maintenant poursuivi par la description détaillée d'exemples de réalisation, donnée ci-après à titre illustratif et non limitatif, en référence aux dessins annexés. Sur ceux-ci :

The description of the invention will now be continued by the detailed description of exemplary embodiments, given below by way of illustration and without limitation, with reference to the appended drawings. On these:
  • the figure 1 is a top view of an installation according to the invention, the artificial wave generator is at rest;
  • the figures 2 and 3 are the sectional views marked by II-II and III-III on the figure 1 ;
  • the figure 4 is a view similar to the figure 1 but with the artificial wave generator in use;
  • the figure 5 is the sectional view marked by VV on the figure 4 ; and

L'installation 10 illustrée sur les figures 1 à 5 comporte une plateforme flottante 11 ici à contour externe circulaire et un générateur de vagues artificielles 12 installé sur la plateforme 11.The illustrated installation 10 on the Figures 1 to 5 comprises a floating platform 11 here with circular outer contour and an artificial wave generator 12 installed on the platform 11.

La plateforme 11 présente une surface supérieure 14 comportant une zone de bord 15, une zone d'évolution de vagues 16 et une zone culminante 17.The platform 11 has an upper surface 14 having an edge zone 15, a wave changing zone 16 and a culminating zone 17.

Le générateur 12 de vagues artificielles comporte quatre éléments 20 d'entraînement d'eau, chacun mobile suivant un trajet prédéterminé 21, qui est ici circulaire.The artificial wave generator 12 has four water-driving elements 20, each movable along a predetermined path 21, which is circular here.

Chaque élément mobile 20 se déplace au-dessus de la zone de bord 15.Each movable member 20 moves over the edge area 15.

L'installation 10 est située dans une étendue d'eau calme, sans ou avec très peu de perturbations telles que des vagues naturelles. Le rivage de l'étendue d'eau est à distance de l'installation 10, qui forme donc une île.The facility 10 is located in a calm expanse of water, without or with very few disturbances such as natural waves. The shoreline of the body of water is remote from the facility 10, which thus forms an island.

Quand le générateur de vagues 12 est au repos, c'est-à-dire lorsque les éléments mobiles 20 sont fixes, la zone culminante 17 est émergée.When the wave generator 12 is at rest, i.e. when the movable elements 20 are fixed, the culminating zone 17 is emerged.

Sur les figures 1 et 4, la limite entre les zones émergées et immergées quand le générateur de vagues est au repos, est représentée par une ligne 18 en trait mixte.On the figures 1 and 4 , the boundary between the emerged and submerged zones when the wave generator is at rest, is represented by a dashed line 18.

Lorsque le générateur de vagues 12 est en service, chaque élément mobile 20 est suivi latéralement, ainsi qu'on le voit bien sur la figure 4, par une vague 22 se déplaçant vers la zone d'évolution de vagues 16, au contact de laquelle la vague 22 générée déferle vers la zone culminante 17.When the wave generator 12 is in use, each movable element 20 is followed laterally, as can be seen in FIG. figure 4 by a wave 22 moving towards the wave changing zone 16, at the contact of which the wave 22 generated breaks towards the culminating zone 17.

La plateforme 11 a par exemple un diamètre de 60 à 80 m voire davantage et les vagues 22 une hauteur de l'ordre de 2 m pour la pratique du surf traditionnel (surfeur debout sur une planche) ; tandis que pour la pratique du surf couché sur une planche appropriée (bodyboard) l'installation a par exemple un diamètre de 18 à 22 m voire davantage et les vagues 22 ont une hauteur de l'ordre de 50 à 60 cm.The platform 11 has for example a diameter of 60 to 80 m or more and the waves 22 a height of about 2 m for the practice of traditional surf (surfer standing on a board); while for the practice of surfing on a board (bodyboard) the installation has for example a diameter of 18 to 22 m or more and the waves 22 have a height of the order of 50 to 60 cm.

Ici, l'étendue d'eau est formée par une anse ou une baie maritime abritée.Here, the body of water is formed by a cove or a sheltered sea bay.

En variante, l'anse ou baie maritime est remplacée par une autre étendue d'eau en environnement naturel, par exemple un lac ou une rivière s'il n'y a pas trop de courant, ou en environnement artificiel, par exemple un bassin en maçonnerie.Alternatively, the cove or sea bay is replaced by another body of water in a natural environment, for example a lake or a river if there is not too much current, or in an artificial environment, for example a pond in masonry.

Le milieu aquatique 23 (ici, la mer) avec lequel coopèrent la plateforme 11 et le générateur de vagues 12 comporte une région 24, appelée région aquatique interne, située au-dessus de la zone de bord 15 et de la zone d'évolution de vagues 16.The aquatic environment 23 (here, the sea) with which the platform 11 and the wave generator 12 cooperate comprises a region 24, called internal aquatic region, located above the edge zone 15 and the wave evolution zone 16.

En outre de la région aquatique interne 24, le milieu aquatique 23 comporte, à l'extérieur de la plateforme 11 le long de la zone de bord 15, une région 25, appelée région aquatique externe supérieure, située plus haut que la zone de bord 15 et une région 26, appelée région aquatique externe profonde, située plus bas que la zone de bord 15.In addition to the internal aquatic region 24, the aquatic medium 23 comprises, outside the platform 11 along the edge zone 15, a region 25, called the upper external aquatic region, situated higher than the edge zone. 15 and a region 26, called deep external aquatic region, located lower than the edge zone 15.

Le milieu aquatique 23 comporte enfin, en-dessous de la plateforme 11, une région 27, appelée région aquatique sous-jacente.The aquatic medium 23 finally comprises, below the platform 11, a region 27, called the underlying aquatic region.

La région aquatique externe profonde 26 et la région aquatique externe supérieure 25 sont contigües horizontalement.The deep external aquatic region 26 and the upper external aquatic region 25 are contiguous horizontally.

La région aquatique interne 24 et la région aquatique externe supérieure 25 sont contigües verticalement.The internal aquatic region 24 and the upper external aquatic region 25 are vertically contiguous.

De même, la région aquatique sous-jacente 27 et la région aquatique externe profonde 26 sont contigües verticalement.Likewise, the underlying aquatic region 27 and the deep outer aquatic region 26 are vertically contiguous.

Il est bien entendu que la subdivision du milieu aquatique 23 en régions aquatiques 24 à 27 est uniquement basée sur la localisation des régions en question par rapport à la plateforme 11, c'est-à-dire que les régions 24 à 27 désignent des lieux où se trouve de l'eau et non des volumes d'eau isolés.It is understood that the subdivision of the aquatic environment 23 into aquatic regions 24 to 27 is solely based on the location of the regions in question with respect to platform 11, that is, regions 24 to 27 designate places where there is water and not isolated volumes of water.

On notera à cet égard qu'il n'y a pas de parois étanches aux liquides isolant les différentes régions aquatiques 24 à 27 les unes des autres.It should be noted in this regard that there are no liquid-tight walls insulating the various aquatic areas 24 to 27 from each other.

Au contraire, l'eau du milieu aquatique 23 (ici, de l'eau de mer) circule entre les différentes régions aquatiques 24 à 27.On the contrary, the water of the aquatic environment 23 (here, seawater) circulates between the different aquatic regions 24 to 27.

Ainsi, quand le générateur de vagues 12 est au repos, l'ensemble du milieu aquatique 23 a le même niveau de surface.Thus, when the wave generator 12 is at rest, the entire aquatic medium 23 has the same surface level.

En particulier, comme on le voit bien sur les figures 1 à 3, le niveau de la surface de la région aquatique interne 24 est identique au niveau de la surface de la région aquatique externe supérieure 25.In particular, as can be seen from the Figures 1 to 3 the level of the surface of the internal aquatic region 24 is identical at the surface level of the upper external aquatic region 25.

Pour protéger les surfeurs contre d'éventuels prédateurs marins, il peut être prévu une grille ou un filet 28 (montré schématiquement sur les seules figures 2, 3 et 5) entre la région aquatique interne 24 et la région aquatique externe supérieure 25. De même, une grille ou un filet (non représenté) peut être prévu autour du trajet 21 pour éviter tout contact entre les éléments mobiles 20 et les surfeurs.To protect the surfers against possible marine predators, it can be provided a grid or net 28 (shown schematically on the only ones figures 2 , 3 and 5 ) between the internal aquatic region 24 and the aquatic region Also, a grid or net (not shown) may be provided around the path 21 to avoid contact between the movable elements 20 and the surfers.

La surface supérieure 14 de la plateforme 11 comporte, en outre de la zone de bord 15, de la zone d'évolution de vagues 16 et de la zone culminante 17, une crête 30 et une zone 31 en dépression par rapport à la crête 30.The upper surface 14 of the platform 11 comprises, in addition to the edge zone 15, the wave evolution zone 16 and the culminating zone 17, a peak 30 and a zone 31 in depression with respect to the ridge 30. .

La crête 30 se trouve entre la zone culminante 17 et la zone en dépression 31. Plus précisément, la crête 30 se trouve entre le sommet de la zone culminante 17 et le sommet de la zone en dépression 31.Ridge 30 is located between the culminating zone 17 and the depression zone 31. Specifically, the ridge 30 is located between the summit of the culminating zone 17 and the summit of the depression zone 31.

Comme on le voit bien sur les figures 4 et 5, la zone culminante 17 et la zone en dépression 31 sont configurées pour que quand le générateur de vagues 12 est en service, l'eau en fin de parcours des vagues 22 franchisse la crête 30 et tombe dans un volume 32 délimité par la zone en dépression 31, ce volume étant appelé volume de recueil.As can be seen from the figures 4 and 5 , the culminating zone 17 and the depression zone 31 are configured so that when the wave generator 12 is in service, the water at the end of the wave travels 22 cross the ridge 30 and falls into a volume 32 delimited by the zone. depression 31, this volume being called collection volume.

Des ouvertures 33 ou 39 ménagées au travers de la plateforme 11 débouchent respectivement dans le volume de recueil 32 et dans la région aquatique sous-jacente 27.Openings 33 or 39 formed through the platform 11 open respectively into the collection volume 32 and into the underlying aquatic region 27.

La région aquatique sous-jacente 27 fournit une communication fluidique reliant la région aquatique externe profonde 26 aux ouvertures 33 ou 39, et donc au volume de recueil 32.The underlying aquatic region 27 provides fluid communication connecting the deep external aquatic region 26 to the openings 33 or 39, and thus to the collection volume 32.

Il en résulte, comme on le voit bien sur les figures 2 et 3, que le niveau de la surface du volume de recueil 32 reste le même que pour l'ensemble du milieu aquatique 23 quand le générateur de vagues 12 est au repos ou, comme on le voit bien sur la figure 5, le même que pour le milieu aquatique 23 en-dehors de la région aquatique interne 24 quand le générateur de vagues 12 est en service.As a result, as can be seen from the figures 2 and 3 , that the level of the surface of the collection volume 32 remains the same as for the whole of the aquatic medium 23 when the wave generator 12 is at rest or, as can be seen clearly on the figure 5 , the same as for the aquatic environment 23 outside the internal aquatic region 24 when the wave generator 12 is in use.

Ainsi, quand le générateur de vagues 12 est en service, l'eau en fin de parcours des vagues 22 quitte la région aquatique interne 24 en tombant dans le volume de recueil 32 d'où elle est évacuée sans passer par la région aquatique interne 24 puisque la communication fluidique est située sous la plateforme 11.Thus, when the wave generator 12 is in use, the water at the end of the waves 22 leaves the internal aquatic region 24 by falling into the collection volume 32 where it is discharged without passing through the internal aquatic region 24 since the fluidic communication is located under the platform 11.

La région aquatique externe supérieure 25 n'est pas non plus perturbée, ou alors très peu, puisque c'est la région aquatique externe profonde 26 qui est en communication avec le volume de recueil 32.The upper external aquatic region 25 is also not disturbed, or very little, since it is the deep external aquatic region 26 that is in communication with the collection volume 32.

La région aquatique interne 24, et d'ailleurs la région aquatique externe supérieure 25, n'étant ainsi pas perturbées par le ressac, ou à tout le moins très peu perturbées, il est possible d'avoir un délai très court entre deux vagues 22 successives.The internal aquatic region 24, and moreover the upper external aquatic region 25, are thus not disturbed by the surf, or at least very little disturbed, it is possible to have a very short delay between two waves 22 successive.

Au surplus, la plateforme 11 est relativement peu sollicitée mécaniquement par les vagues 22 puisque l'eau est guidée vers le volume de recueil 32 à partir duquel elle rejoint naturellement la région aquatique sous-jacente 27 qui communique avec la région aquatique externe profonde 26.Moreover, the platform 11 is relatively little mechanically solicited by the waves 22 since the water is guided to the collection volume 32 from which it naturally reaches the underlying aquatic region 27 which communicates with the deep external aquatic region 26.

On va maintenant expliquer comment la plateforme 11, qui est flottante ainsi qu'indiqué ci-dessus, est maintenue en place dans le milieu aquatique 23.We will now explain how the platform 11, which is floating as indicated above, is held in place in the aquatic environment 23.

D'une façon générale, la flottabilité de la plateforme 11 est prévue pour que la zone de bord 15 soit à une distance prédéterminée sous le niveau de surface du milieu aquatique 23.In general, the buoyancy of the platform 11 is provided so that the edge zone 15 is at a predetermined distance below the surface level of the aquatic medium 23.

Cette distance prédéterminée est celle qui convient pour le bon fonctionnement du générateur de vagues 12.This predetermined distance is that suitable for the proper operation of the wave generator 12.

Pour maintenir la plateforme 11 vis-à-vis du fond 35 du milieu aquatique 23, des liens 36 tels que des chaines sont prévus entre la plateforme 11 et des corps-morts 37 posés sur le fond 35.To maintain the platform 11 opposite the bottom 35 of the aquatic environment 23, links 36 such as chains are provided between the platform 11 and mooring 37 placed on the bottom 35.

Il est également prévu un pieu 38 fixé au fond 35, engagé dans une ouverture centrale 39 de la plateforme 11.There is also provided a pile 38 fixed to the bottom 35, engaged in a central opening 39 of the platform 11.

Lors des changements de niveau de surface de la plateforme dus à la marée, la plateforme 11 coulisse vis-à-vis du pieu 38 et les liens 36 retiennent la plateforme 11, en particulier pour éviter qu'elle tourne autour du pieu 38.During changes in the surface level of the platform due to the tide, the platform 11 slides vis-à-vis the pile 38 and the links 36 hold the platform 11, in particular to prevent it turns around the pile 38.

En variante, la plateforme 11 est maintenue différemment vis-à-vis du fond 35, par exemple uniquement avec des liens tels que 36 ou uniquement avec des pieux tels que 38.As a variant, the platform 11 is maintained differently with respect to the bottom 35, for example only with links such as 36 or only with piles such as 38.

Ici, la plateforme 11 est fabriquée en matériaux composites à la façon d'une paroi de coque de bateau.Here, the platform 11 is made of composite materials in the manner of a boat hull wall.

En variante, les matériaux composites sont remplacés par d'autres matières utilisées pour la fabrication des coques de bateaux, par exemple de l'aluminium ou du bois.Alternatively, the composite materials are replaced by other materials used for the manufacture of boat hulls, for example aluminum or wood.

Pour ajuster la flottabilité de la plateforme 11, il est prévu des caissons (non représentés) pouvant être plus ou moins remplis d'eau.To adjust the buoyancy of the platform 11, there are provided caissons (not shown) may be more or less filled with water.

En utilisation normale, les caissons sont remplis pour ajuster la flottabilité comme il vient d'être indiqué, c'est-à-dire pour que la zone de bord 15 soit à la distance prédéterminée voulue sous le niveau de surface du milieu aquatique.In normal use, the caissons are filled to adjust the buoyancy as just indicated, i.e., so that the edge zone 15 is at the desired predetermined distance below the surface level of the aquatic environment.

Si l'on désire que la plateforme 11 émerge davantage, par exemple pour des opérations de maintenance, les caissons sont vidés.If it is desired that the platform 11 emerges more, for example for maintenance operations, the boxes are emptied.

Si l'on désire que la plateforme 11 s'enfonce davantage, par exemple pour reposer sur le fond 35 en cas de tempête, les caissons sont remplis.If it is desired that the platform 11 sinks further, for example to rest on the bottom 35 in case of storm, the boxes are filled.

En variante, la plateforme 11 n'est pas flottante mais par exemple soutenue par des pylônes fixés sur le fond 35.As a variant, the platform 11 is not floating but for example supported by pylons fixed to the bottom 35.

En outre de la plateforme 11 et du générateur de vagues 12, l'installation 10 comporte un épi 40 assujetti à la plateforme 11.In addition to the platform 11 and the wave generator 12, the installation 10 comprises an epee 40 secured to the platform 11.

L'épi 40 saille vers le haut depuis la zone d'évolution de vagues 16 en s'étendant au travers de la région aquatique interne 24 depuis la zone culminante 17 vers la zone de bord 15.The spike 40 protrudes upwardly from the wave evolution zone 16 by extending through the internal water region 24 from the culminating zone 17 to the edge zone 15.

L'épi 40 présente une surface supérieure 41 comportant une première zone latérale 42, une deuxième zone latérale 43 située du côté opposé à la première zone latérale 42 et une zone intermédiaire 44 s'étendant de la première zone latérale 42 à la deuxième zone latérale 43.The spike 40 has an upper surface 41 having a first lateral zone 42, a second lateral zone 43 situated on the side opposite to the first lateral zone 42 and an intermediate zone 44 extending from the first lateral zone 42 to the second lateral zone. 43.

Ici, la zone intermédiaire 44 comporte une première crête 45 et une deuxième crête 46, chacune émergée quand le générateur de vagues 12 est au repos.Here, the intermediate zone 44 has a first peak 45 and a second peak 46, each emerging when the wave generator 12 is at rest.

La zone intermédiaire 44 comporte également une zone 47 en dépression par rapport à la première crête 45 et à la deuxième crête 46, la première crête 45 se trouvant entre la première zone latérale 42 et la zone en dépression 47, la deuxième crête 46 se trouvant entre la deuxième zone latérale 43 et la zone en dépression 47.The intermediate zone 44 also comprises a zone 47 in depression with respect to the first peak 45 and the second peak 46, the first peak 45 being located between the first lateral zone 42 and the zone 46. depression 47, the second peak 46 being between the second lateral zone 43 and the depression zone 47.

Plus précisément, la première crête 45 se trouve entre le sommet de la première zone latérale 42 et l'un des deux sommets de la zone en dépression 47 ; et la deuxième crête 46 se trouve entre le sommet de la deuxième zone latérale 43 et l'autre sommet la zone en dépression 47.More precisely, the first peak 45 is located between the top of the first lateral zone 42 and one of the two vertices of the depression zone 47; and the second peak 46 is between the top of the second lateral zone 43 and the other vertex the depression zone 47.

La première crête 45, la deuxième crête 46 et la zone en dépression 47 sont configurées pour que quand le générateur de vagues 12 est en service, l'eau en fin de parcours des vagues 22 franchisse la première crête 45 ou la deuxième crête 46 et tombe dans un volume 48 délimité par la zone en dépression 47, appelé ci-après volume de recueil.The first peak 45, the second peak 46 and the depression zone 47 are configured so that when the wave generator 12 is in use, the water at the end of the wave travels 22 past the first peak 45 or the second peak 46 and falls into a volume 48 delimited by the depression zone 47, hereinafter referred to as the collection volume.

Ici, le volume de recueil 48 de l'épi 40 et le volume de recueil 32 de la plateforme 11 sont contigus verticalement.Here, the collection volume 48 of the spike 40 and the collection volume 32 of the platform 11 are contiguous vertically.

Plus précisément, ici, comme on le voit bien sur les figures 1 à 3, la zone en dépression 47 qui délimite le volume de recueil 48 a un profil en U et la zone en dépression 31 qui délimite le volume de recueil 32 est de forme générale tronconique avec une interruption au droit de l'épi 40. Les zones en dépression 31 et 47 se raccordent au niveau de l'interruption.More precisely, here, as we see well on Figures 1 to 3 , the zone in depression 47 which delimits the collection volume 48 has a U-shaped profile and the depression zone 31 which delimits the collection volume 32 is of frustoconical general shape with an interruption at the right of the spike 40. The zones depression 31 and 47 are connected at the interruption.

La crête 30 de la plateforme 11 se raccorde à une extrémité à la première crête 45 de l'épi 40 et se raccorde à l'autre extrémité à la deuxième crête 46 de l'épi 40.The ridge 30 of the platform 11 is connected at one end to the first ridge 45 of the spike 40 and is connected at the other end to the second ridge 46 of the spike 40.

Du côté opposé à celui où il se raccorde au volume de recueil 32, le volume de recueil 48 débouche ici au niveau de la jonction entre la zone d'évolution de vagues 16 et la zone de bord 15.On the side opposite to the one where it is connected to the collection volume 32, the collection volume 48 opens here at the junction between the wave evolution zone 16 and the edge zone 15.

Le volume de recueil 48 est ainsi en communication fluidique avec la région aquatique externe supérieure 25 via la partie de la région aquatique interne 24 qui est située au-dessus de la zone de bord 15.The collection volume 48 is thus in fluid communication with the upper external aquatic region 25 via the portion of the inner aquatic region 24 which is located above the edge zone 15.

Des ouvertures 49, semblables aux ouvertures 33, sont ménagées au travers de la partie la plus basse de la paroi qui forme la zone en dépression 47. Les ouvertures 49 débouchent respectivement dans le volume de recueil 48 et dans la région aquatique sous-jacente 27.Apertures 49, similar to the apertures 33, are formed through the lower part of the wall which forms the depression zone 47. The openings 49 open respectively into the collection volume 48 and into the underlying aquatic region 27 .

Le volume de recueil 48 est ainsi en communication fluidique, via la région aquatique sous-jacente 27, avec la région aquatique externe profonde 26.The collection volume 48 is thus in fluid communication, via the underlying aquatic region 27, with the deep external aquatic region 26.

L'eau en fin de parcours des vagues tombée dans le volume de recueil 48 est ainsi évacuée vers la région aquatique externe profonde 26 et/ou la région aquatique externe supérieure 25.The water at the end of the wave path that has fallen into the collection volume 48 is thus discharged to the deep external aquatic region 26 and / or the upper external aquatic region 25.

Le volume de recueil 48, du fait qu'il rejoint le volume de recueil 32, peut participer à l'évacuation de l'eau tombée dans le volume de recueil 32.The collection volume 48, since it reaches the collection volume 32, can participate in the evacuation of the water that has fallen into the collection volume 32.

L'assujettissement entre la plateforme 11 et l'épi 40 est ici réalisé du fait que la plateforme 11 et l'épi 40 sont d'une seule pièce, la plateforme 11 et l'épi 40 étant fabriqués conjointement en matériaux composites à la façon d'une paroi de coque de bateau.The subjection between the platform 11 and the spur 40 is here realized because the platform 11 and the spike 40 are in one piece, the platform 11 and the spike 40 being made jointly in composite materials in the manner of a boat hull wall.

En variante, les matériaux composites sont remplacés par d'autres matières utilisées pour la fabrication des coques de bateaux, par exemple de l'aluminium ou du bois.Alternatively, the composite materials are replaced by other materials used for the manufacture of boat hulls, for example aluminum or wood.

En variante, l'épi 40 est une pièce rapportée sur la plateforme 11.In a variant, the spike 40 is an insert on the platform 11.

Le générateur de vagues 12 comporte, ainsi qu'indiqué ci-dessus, quatre éléments 20 d'entraînement d'eau, chacun mobile suivant le trajet prédéterminé 21, qui est ici circulaire.The wave generator 12 comprises, as indicated above, four water-driving elements 20, each movable along the predetermined path 21, which is circular here.

Chaque élément mobile 20 se déplace au-dessus de la zone de bord 15, dans le sens montré par des flèches sur la figure 4, en entraînant de l'eau vers la zone d'évolution de vagues 16.Each movable member 20 moves above the edge area 15, in the direction shown by arrows on the figure 4 , by drawing water towards the wave evolution zone 16.

Plus précisément, chaque élément mobile 20 est suivi latéralement par une vague 22 se déplaçant vers la zone d'évolution de vagues 16. Au contact de la zone d'évolution de vagues 16, la vague 22 déferle vers la zone culminante 17.More specifically, each movable element 20 is followed laterally by a wave 22 moving towards the wave changing zone 16. In contact with the wave changing zone 16, the wave 22 breaks towards the culminating zone 17.

Les éléments mobiles 20 sont disposés sur le trajet 21 en étant équidistants angulairement.The movable elements 20 are arranged on the path 21 being equidistant angularly.

Les générateurs de vagues artificielles étant bien connus, le générateur 12 ne sera pas décrit davantage ici.Since artificial wave generators are well known, the generator 12 will not be described further here.

Pour plus de détails, on pourra se reporter notamment au brevet américain 3,913,332.For more details, see in particular US Patent 3,913,332.

On notera qu'il est possible de conformer les éléments mobiles 20 pour qu'ils puissent également générer des vagues en se déplaçant dans le sens inverse à celui illustré sur la figure 4.Note that it is possible to conform the movable elements 20 so that they can also generate waves by moving in the opposite direction to that illustrated on the figure 4 .

L'installation selon l'invention offre ainsi aux surfeurs la possibilité d'évoluer sur des vagues à droite ou sur des vagues à gauche, suivant le sens de déplacement des éléments mobiles 20.The installation according to the invention thus offers surfers the possibility of moving on waves on the right or on waves on the left, depending on the direction of movement of the mobile elements 20.

La surface supérieure 14 de la plateforme 11 comporte ici, entre la zone de bord 15, qui est horizontale, et la zone d'évolution de vagues 16, qui est inclinée, une zone d'épaulement 50 qui est verticale ou sensiblement verticale.The upper surface 14 of the platform 11 here comprises, between the edge zone 15, which is horizontal, and the wave changing zone 16, which is inclined, a shoulder zone 50 which is vertical or substantially vertical.

La zone d'épaulement 50 crée un obstacle à la propagation de l'eau mise en mouvement par l'élément mobile 20, ce qui est favorable à la qualité, pour la pratique du surf, de la vague générée avant qu'elle déferle sur la zone d'évolution de vagues 16.The shoulder zone 50 creates an obstacle to the propagation of the water set in motion by the mobile element 20, which is favorable to the quality, for the practice of surfing, of the wave generated before it sweeps over the wave evolution zone 16.

L'épi 40, qui est disposé en travers de la région aquatique interne 24, permet d'interrompre un éventuel courant d'eau tournant autour de la zone culminante 17.The spike 40, which is arranged across the internal aquatic region 24, interrupts a possible flow of water rotating around the culminating zone 17.

On notera en particulier que les vagues 22 sont arrêtées par l'épi 40 ; et qu'après que l'élément mobile 20 a franchi l'épi 40 une nouvelle vague 22 démarre dans une eau calme ou en tout cas qui n'a pas été perturbée par la vague 22 précédente.It will be noted in particular that the waves 22 are stopped by the spike 40; and after the movable member 20 has passed the spike 40 a new wave 22 starts in calm water or in any case that has not been disturbed by the previous wave 22.

La présence de la région aquatique externe supérieure 25 est également favorable à la limitation des courants dans la région aquatique interne 24.The presence of the upper external aquatic region is also favorable to the limitation of currents in the internal aquatic region 24.

En variante, l'épi est mis en oeuvre dans une installation où il n'y a pas de région aquatique externe.Alternatively, the spike is implemented in a facility where there is no external aquatic region.

Pour éviter autant que possible le ressac, la première zone latérale 42 de l'épi 40, qui est celle qui la plus sollicitée par les vagues 22 puisque les éléments mobiles 20 tournent dans le sens où ils se rapprochent de cette zone latérale, est pourvu de flèches 51.To avoid as much as possible the surf, the first lateral zone 42 of the spike 40, which is the one that is the most stressed by the waves 22 since the movable elements 20 rotate in the direction that they are approaching this lateral zone, is provided with arrows 51.

Ainsi qu'expliqué ci-dessus, l'épi 40 sert également à l'évacuation de l'eau en fin de parcours des vagues.As explained above, the spike 40 is also used for the evacuation of water at the end of the wave course.

Pour éviter que les éléments mobiles 20 fassent entrer de l'eau dans le volume de recueil 48, on met en oeuvre des mesures appropriées, par exemple un volet qui ferme le débouché vers l'extérieur du volume de recueil 48 quand l'élément mobile 20 passe devant, ou le trajet 21 est configuré pour que les éléments mobiles 20 passent au-dessus de la surface de l'eau à cet endroit.In order to prevent the mobile elements 20 from introducing water into the collection volume 48, appropriate measures are implemented, for example a flap which closes the outlet towards the outside of the collection volume 48 when the mobile element 20 passes by, or the path 21 is configured so that the movable elements 20 pass over the surface of the water at that location.

En variante, l'épi 40 ne comporte pas de volume de recueil 48, par exemple en ayant la zone intermédiaire 44 de sa surface supérieure 41 qui est remplacée par une simple crête.Alternatively, the spike 40 has no collection volume 48, for example by having the intermediate zone 44 of its upper surface 41 which is replaced by a simple ridge.

Dans une autre variante non représentée, l'installation 10 ne comporte pas d'épi tel que l'épi 40.In another variant not shown, the installation 10 has no spike such as the spike 40.

On va maintenant décrire à l'appui de la figure 6 une variante de l'installation 10.We will now describe in support of the figure 6 a variant of the installation 10.

Par commodité, on a gardé pour les éléments semblables les mêmes références numériques que pour l'installation 10 illustrée sur les figures 1 à 5.For convenience, the same reference numerals have been kept for similar elements as for the illustrated installation 10 Figures 1 to 5 .

D'une façon générale, l'installation 10 illustrée sur la figure 6 est semblable à l'installation 10 illustrée sur les figures 1 à 5, si ce n'est que le support qui fournit la surface supérieure 14 n'est pas une plateforme située au-dessus d'une région aquatique sous-jacente mais un substrat 55 faisant partie du sol et entouré par un bassin annulaire 56 dont la surface de fond 54 est bien plus basse que la zone de bord 15 ; et que l'eau du milieu aquatique 23 est de l'eau traitée, en l'occurrence de l'eau de piscine.In general, the installation 10 illustrated on the figure 6 is similar to the installation 10 illustrated on Figures 1 to 5 except that the support which provides the upper surface 14 is not a platform situated above an underlying aquatic region but a substrate 55 forming part of the ground and surrounded by an annular basin 56 whose bottom surface 54 is much lower than the edge area 15; and that the water of the aquatic medium 23 is treated water, in this case pool water.

Pour mettre en oeuvre la communication fluidique située sous la surface supérieure 14 du support que forme le substrat 55, des conduits 57 sont ménagés dans le substrat 55. Chaque conduit 57 débouche à une extrémité, par une ouverture 58, dans le volume de recueil 32 du substrat 55 et, à l'autre extrémité, par une ouverture 59, dans la région aquatique profonde 26.To implement the fluid communication located under the upper surface 14 of the support that forms the substrate 55, conduits 57 are formed in the substrate 55. Each conduit 57 opens at one end, through an opening 58, into the collection volume 32 of the substrate 55 and, at the other end, through an opening 59, in the deep aquatic region 26.

Ici, le substrat 55 et le bassin annulaire 56 sont formés par un ouvrage en maçonnerie.Here, the substrate 55 and the annular basin 56 are formed by a masonry structure.

Dans des variantes non représentées :

  • le nombre d'éléments mobiles tels que 20 du générateur de vagues tel que 12 est différent de quatre, par exemple un seul, deux, trois ou davantage que quatre ;
  • un îlot émergé est prévu au centre du volume de recueil tel que 32 du support tel que la plateforme 11 ou le substrat 55, par exemple un îlot sur lequel sont disposés des bâtiments ;
  • le trajet tel que 21 du ou des éléments mobiles tels que 20, et donc le contour du support tel que la plateforme 11 ou le substrat 55 est annulaire sans être circulaire, par exemple ovale, oblong et/ou avec des ondulations ; ou encore ce trajet n'est pas annulaire, par exemple rectiligne ou incurvé.
In variants not shown:
  • the number of moving elements such as the wave generator such as 12 is different from four, for example one, two, three or more than four;
  • an emergent island is provided in the center of the collection volume such as 32 of the support such as the platform 11 or the substrate 55, for example an island on which are arranged buildings;
  • the path such as 21 of the movable element or elements such as 20, and therefore the contour of the support such as the platform 11 or the substrate 55 is annular without being circular, for example oval, oblong and / or with corrugations; or this path is not annular, for example rectilinear or curved.
