Abstract

The system has an impeller (1) whose axis is maintained parallel to a surface of water and perpendicular to the direction of water current (8) such that lower blades are immersed in the water and upper blades are released from the water. Rotation unit freely rotates the impeller around the axis, and mooring lines (6) prevent an assembly to be driven by current. An electric generator (5) converts the mechanical energy from the rotation of the impeller into electrical energy. A wheel rotate between catamaran type lateral floats (2) that are profiled to carry out nozzle effect on the wheel.

Description

La présente invention concerne un système de production d'énergieThe present invention relates to a power generation system

hydroélectrique par transformation de l'énergie 5 cinétique d'un courant d'eau fluvial ou marin.  hydroelectric by transformation of the kinetic energy of a fluvial or marine water stream.

Les systèmes connus selon la technique actuelle pour effectuer cette transformation utilisent principalement une ou plusieurs hélices à axe horizontal ou vertical tournant dans un 10 plan orthogonal au courant.  The known systems according to the present technique for carrying out this transformation mainly use one or more propellers with a horizontal or vertical axis rotating in a plane orthogonal to the current.

L'inconvénient de ces systèmes actuels est qu'ils nécessitent de grandes infrastructures fixées au fond pour maintenir l'hélice dans l'eau. Ces grandes infrastructures sont 15 coûteuses à l'installation, difficiles à maintenir et à démanteler. S'ils sont fixés sous des plate-formes flottantes, les mouvements de la plateforme en surface perturbent le fonctionnement des hélices. Ils sont en outre d'un fonctionnement délicat en raison de leur technologie sous- 20 marine, et les vitesses en bout de pale sont génératrices de cavitation. Le but de la présente invention est de remédier à ces inconvénients par un système de production d'énergie 25 hydroélectrique flottant sur la surface de l'eau, cette caractéristique le rendant aisément déplaçable pour son installation ou son entretienä Il permet aussi au groupe de génération d'énergie de fonctionner, sous protection des embruns, mais à l'air libre et non pas en caisson étanche sous- 30 marin. Ce système flottant est attaché au sol par une ou plusieurs lignes de mouillage et ne nécessite donc pas d'infrastructure fixe autre que le point d'ancrage de ces lignes de mouillage sur le fond.  The disadvantage of these current systems is that they require large infrastructure attached to the bottom to maintain the propeller in the water. These large infrastructures are expensive to install, difficult to maintain and dismantle. If they are fixed under floating platforms, the movements of the surface platform disrupt the operation of the propellers. They are also delicate in operation because of their underwater technology, and the blade tip speeds are cavitation-generating. The object of the present invention is to overcome these drawbacks by a hydroelectric power generation system floating on the surface of the water, this characteristic making it easily movable for its installation or maintenance. It also allows the generator group of energy to operate, under spray protection, but in the open air and not underwater waterproof box. This floating system is attached to the ground by one or more anchor lines and therefore does not require fixed infrastructure other than the anchor point of these anchor lines on the bottom.

L'invention a pour caractéristique de comporter au moins une roue à aubes dont l'axe de rotation est orienté parallèlement à la surface de l'eau et perpendiculairement à la direction du courant. Cette roue peut elle-même être flottante ou est soutenue par un ou plusieurs flotteurs latéraux de telle sorte que ses aubes inférieures plongent dans l'eau et sont soumises à la poussée du courant, et ses aubes supérieures sortent de l'eau. La roue à aubes qui tourne autour de ses paliers est mise en rotation par le courant d'eau qui appuie sur ses pales immergées.  The invention has the characteristic of comprising at least one impeller whose axis of rotation is oriented parallel to the surface of the water and perpendicular to the direction of the current. This wheel can itself be floating or is supported by one or more lateral floats so that its lower blades dive into the water and are subject to the thrust of the current, and its upper blades out of the water. The paddle wheel which rotates around its bearings is rotated by the stream of water which presses on its immersed blades.

Les flotteurs latéraux, de type catamaran, sont également conçus pour accentuer l'effet tuyère sur la roue et ainsi augmenter son efficacité. De la même façon un plancher placé entre les flotteurs sous la roue permet d'éviter les pertes par en dessous. On peut éventuellement augmenter encore l'efficacité de l'installation en installant, à. chaque extrémité des flotteurs et sur le plancher au fond, des volets amovibles qui en s'ouvrant à l'extérieur vont canaliser vers la roue une quantité d'eau en mouvement supérieure.  The side floats, catamaran type, are also designed to accentuate the nozzle effect on the wheel and thus increase its efficiency. In the same way a floor placed between the floats under the wheel makes it possible to avoid losses from below. The efficiency of the installation can be further increased by installing, at. each end of the floats and on the floor at the bottom, removable flaps that open to the outside will channel to the wheel a greater amount of water moving.

La roue entraîne un générateur qui convertit une partie de l'énergie de rotation de la roue à aubes en énergie électrique.  The wheel drives a generator that converts a portion of the rotational energy of the impeller into electrical energy.

L'énergie électrique produite par le générateur est éventuellement transformée et régulée puis acheminée vers la terre par câble électrique. Dans une variante possible de l'invention, l'énergie électrique provenant du générateur sert à la production sur place d'hydrogène obtenu par hydrolyse de l'eau. Une autre variante permet de transformer l'eau de mer en eau douce par utilisation directe de l'énergie mécanique de la roue.  The electrical energy produced by the generator is optionally transformed and regulated and then sent to earth by electric cable. In a possible variant of the invention, the electrical energy from the generator is used for the on-site production of hydrogen obtained by hydrolysis of water. Another variant makes it possible to transform seawater into fresh water by direct use of the mechanical energy of the wheel.

3 D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée, ci-dessous. Cette description sera faite en regard des dessins annexés illustrant à titre d'exemple non limitatif un système de production d'énergie hydroélectrique par transformation de l'énergie cinétique d'un courant marin selon l'invention. La figure 1 montre une vue d'ensemble du système comprenant une roue à aubes (1) dont l'axe est maintenu sur la structure (4) par le moyen de paliers (3) et entraîne un générateur (5) sous l'effet du courant d'eau (8). La structure (4) est amarrée au fond par une ligne de mouillage (6). L'efficacité de la roue est améliorée par des flotteurs latéraux (2) et d'un fond situé sous la roue (7) qui canalisent des filets d'eau vers la roue à aubes.15Other features and advantages of the invention will become apparent from the detailed description below. This description will be made with reference to the accompanying drawings illustrating by way of nonlimiting example a system for producing hydroelectric energy by transforming the kinetic energy of a marine current according to the invention. FIG. 1 shows an overall view of the system comprising a impeller (1) whose axis is held on the structure (4) by means of bearings (3) and drives a generator (5) under the effect water flow (8). The structure (4) is anchored to the bottom by a wetting line (6). The efficiency of the wheel is improved by lateral floats (2) and a bottom located under the wheel (7) which channel streams of water to the impeller.
