Abstract

The invention relates to a floating power station intended to recover energy from the swell. It consists of an inclined plane forming an artificial beach 4 secured to a collection container 11, and a calming chamber 12, the whole thing being supported by a semi-submersible structure 1 with respect to which it can have an adjustable vertical movement. This power station may be used to supply energy to factories or to floating storage, to off-shore platforms, or to built up areas along the shore.

Description

La présente invention concerne une centrale flottante semisubmersible destinée à récupérer en mer l'énergie de la houle.Elle est la juxtaposition nouvelle de moyens connus et de moyens nouveaux. The present invention relates to a semisubmersible floating power station intended to recover at sea the energy of the swell. It is the new juxtaposition of known means and new means.

Dans l'etat actuel de la technique, on connait des plans inclinés fixes installés à terre sur des plages où la houle est assez régulière, et qui sont destinés à créer, dans un réservoir plaçé derrière eux, une réserve d'eau turbinable dont la hauteur utilisable est obtenue par le déferlement de cette houle provoqué par le plan incliné. In the current state of the art, there are fixed inclined planes installed on land on beaches where the swell is fairly regular, and which are intended to create, in a reservoir placed behind them, a reserve of turbinable water whose usable height is obtained by the surge of this swell caused by the inclined plane.

Ces plans inclinés fixes ne sont réellement éfficaces que pour une amplitude bien particulière de la houle. These fixed inclined planes are only really effective for a very specific amplitude of the swell.

L' auteur de la présente invention a par ailleurs décrit précedemment des dispositifs de plages artificielles installés en mer, sur des structures fixes ou sur des catamarans ( Certificat d'utilité 7914850, et certificat d'addition 7922581). The author of the present invention has also previously described artificial beach devices installed at sea, on fixed structures or on catamarans (Utility certificate 7914850, and addition certificate 7922581).

Le but de la présente invention est de placer un tel plan incliné, dans une position réglable, à l'intérieur d'une structure de plateforme connue, semisubmersible, située en mer, de façon à pouvoir exploiter, dans sa direction la plus favorable, la houle plus au large, là où elle est la plus importante, et de povoir exploiter l'éventail le plus large possible des amplitudes de cette houle. The object of the present invention is to place such an inclined plane, in an adjustable position, inside a known platform structure, semi-submersible, located at sea, so as to be able to operate, in its most favorable direction, the swell further offshore, where it is greatest, and to be able to exploit the widest possible range of amplitudes of this swell.

Un réservoir de tranquilisation est également adjoint à ce dispositif pour obtenir une meilleure régularisation du débit des turbines. A still tank is also added to this device to obtain better regulation of the turbine flow rate.

Selon une forme préferentielle de réalisation illustrée par la figure I, le support marin est une plateforme semisubmersible d'un type analogue à celles utilisées dans l'industrie du pétrole off-shore, par exemple constitué de flotteurs organisés sous forme de colonnes verticales telles que (I),(2), et (3), disposées en deux rangées parallèles encadrant la plage artificielle (4). According to a preferred embodiment illustrated in FIG. I, the marine support is a semi-submersible platform of a type analogous to those used in the offshore oil industry, for example made up of floats organized in the form of vertical columns such as (I), (2), and (3), arranged in two parallel rows framing the artificial beach (4).

Ces rangées sont fixées respectivement sur deux caissons rectangulaires immergés tels que (5) rendus solidaires l'un de l'autre par des caissons transversaux (6) et (6) également immergés. These rows are fixed respectively on two submerged rectangular boxes such as (5) made integral with one another by transverse boxes (6) and (6) also submerged.

De son coté la plage artificielle est formée de deux plans inclinés successifs (8) et (9), et dun rebord de deferlement (10),eux mèmes solidaires d'un reservoir de recueil (11) et d'un réservoir de tranquilisation (12). For its part, the artificial beach is formed by two successive inclined planes (8) and (9), and by a surge edge (10), themselves secured to a collection reservoir (11) and a tranquilization reservoir ( 12).

La plage artificielle, le réservoir de recueil, et le reservoir de tranquilisation forment un ensemble solidaire, et cet ensemble est monté sur des glissières verticales telles que (13) et peut se déplacer verticalement par rapport à la structure semisubmersible constituée par les colonnes telles que (1), (2), (3) et les caissons tels que (5), (6), (7).The artificial beach, the collection tank, and the stilling tank form an integral assembly, and this assembly is mounted on vertical slides such as (13) and can move vertically relative to the semi-submersible structure constituted by the columns such as (1), (2), (3) and the boxes such as (5), (6), (7).

Ce déplacement vertical peut, par exemple, ètre commandé par quatre vérins hydrauliques connus tels que (14) ou (15). This vertical movement can, for example, be controlled by four known hydraulic cylinders such as (14) or (15).

Au bas et à l'arrière du réservoir de recueil (11) sont disposés plusieurs orifices tels que (16), (17), ou(18), qui assurent la communication du réservoir de recueil avec le reservoir de tranquilisation (12), et qui contiennent chacun un groupe bulbe turbogénérateur connu tel que (19). At the bottom and at the rear of the collection tank (11) are arranged several orifices such as (16), (17), or (18), which ensure the communication of the collection tank with the stilling tank (12), and which each contain a known turbine generator group such as (19).

Tous les orifices tels que (16), (17) peuvent ètre obturés par un dispositif connu, suivant le débit produit par l'arrivée des vagues déf,erlantes-dans le réservoir de recueil. All the orifices such as (16), (17) can be closed by a known device, according to the flow produced by the arrival of def, erlantes-waves in the collection tank.

Le réservoir de tranquilisation (12) communique avec la mer par un large clapet de non-retour (20) dont le débit est supérieur à celui de la totalité des orifices tels que (16) et (17), de sorte que le niveau moyen dans ce réservoir est inférieur ou égal au niveau moyen de la mer2arrière lui. The still tank (12) communicates with the sea by a large non-return valve (20) whose flow rate is greater than that of all the orifices such as (16) and (17), so that the average level in this reservoir is less than or equal to the mean sea level behind it.

La plage artificielle (4) est délimitée latéralement par deux plaques verticales (21) et (22) formant a l'avant de la plateforme une entrée converyente pour la houle. The artificial beach (4) is delimited laterally by two vertical plates (21) and (22) forming at the front of the platform a converging entry for the swell.

Enfin l'ensemble peut ètre ancré par une ligne d'ancre en forme de Y (23) attachée aux caissons en des points tels que (24), et fixée à son autre extrémité à un pieu foré dans le sol marin (25), ou ancré à un mat

oscillant (26) ce qui permet à la plateforme semisubmersible de décrire eventuellement un cercle autour de ce point et de s'orienter ainsi au mieux face à la houle incidente quelle que soit sa direction.Finally, the assembly can be anchored by a Y-shaped anchor line (23) attached to the caissons at points such as (24), and fixed at its other end to a pile drilled in the sea floor (25), or anchored to a mast

oscillating (26) which allows the semi-submersible platform to possibly describe a circle around this point and to orient itself as best as possible facing the incident swell whatever its direction.

Le dispositif proposé par l'invention peut ètre installé environ à 30 miles de la côte, et sert à récupérer l'énergie de la houle en la transformant en énergie électrique. Il peut alimenter en courant une agglomération sur le rivage à laquelle il est alors relié par un cable sous-marin (fig.2), ou servir de source d'énergie électrique à des installations en mer telles des plateformes pétrolières,des usines, ou des stockages flottants auquel cas il peut ètre installé à couple (fig.3) ou mème intégré à ces installations (f ig  The device proposed by the invention can be installed approximately 30 miles from the coast, and is used to recover the energy of the swell by transforming it into electrical energy. It can supply current to a built-up area on the shore to which it is then connected by an underwater cable (fig. 2), or serve as a source of electrical energy at offshore installations such as oil platforms, factories, or floating storage in which case it can be installed with torque (fig. 3) or even integrated into these installations (f ig
