Abstract

The turbine has a reversible wheel (A) with flexible paddle blades (6) that are made of elastic or flexible materials, so that the blades deform in cup shape when the blades are subjected to the action of tidal current. Each blade is released from the cup shape and returns to rest position when the current is not obtained. Rotational direction of an axle (7) corresponding to the tidal current permits transmission of the force obtained by water pressure on the cups of the blades to an intensity or pressure generator.

Description

-1-DESCRIPTION La présente invention concerne une hydrolienne, dont le sens de rotation de la roue à aubes à pales flexibles en godets est réversible. Cette hydrolienne est destinée à être installée sur un flotteur quelconque à poste fixe dans un site à courants de marée. Elle prend en compte les avantages des roues à godets d'un rendement très supérieur à celui des roues à aubes à pales plates. Des hydroliennes à pales plates ou à godets existent, mais ne concernent que des courants d'eau arrivant d'un même sens. Elles sont installées sur des flotteurs dans de nombreux fleuves et plus récemment, en mer, où, pour tenir compte de l'inversion de ces courants de marée, ces hydroliennes pivotent autour d'un point d'amarrage fixe, comme un bateau autour de son ancre, de façon à ce que la roue à aubes tourne toujours dans le même sens malgré l'inversion du courant de marée. L'hydrolienne à roue réversible à aubes à pales flexibles, en godets, fig : 1 (A) est constituée d'un flotteur (1) pouvant s'élever ou s'abaisser en fonction des hauteurs des marées. Il est maintenu à poste fixe par des poteaux verticaux (8) ou par tous autres moyens quelconques. Dans ce flotteur (1) est ménagée une ouverture (B) dans laquelle vient s'insérer une roue (A) à plusieurs aubes (6) supportée par les bras de l'ensemble de réglage de niveau (4). Cet ensemble de réglage de niveau est fixé et articulé sur le flotteur (1) par les chaises de support (2). Le dispositif (3), manuel ou assisté mécaniquement, permet le réglage de la hauteur de la roue à aubes (A) et l'immersion dans le courant de marée en fonction de l'action souhaitée du courant sur les pales des aubes (6) et du niveau des marées les plus basses. The present invention relates to a tidal turbine, whose direction of rotation of the paddle wheel with flexible blades in buckets is reversible. This tidal turbine is intended to be installed on any float fixed station in a tidal stream site. It takes into account the advantages of bucket wheels with a much higher efficiency than flat paddle wheels. Spiral turbines with flat blades or buckets exist, but concern only streams of water arriving from the same direction. They are installed on floats in many rivers and more recently, at sea, where, to account for the inversion of these tidal currents, these tidal turbines rotate around a fixed mooring point, like a boat around its anchor, so that the paddle wheel always rotates in the same direction despite the inversion of the tidal stream. The reversible-wheel turbine with flexible vanes, in buckets, fig: 1 (A) consists of a float (1) that can rise or fall depending on the height of the tides. It is held stationary by vertical posts (8) or by any other means. In this float (1) is formed an opening (B) in which is inserted a wheel (A) with multiple blades (6) supported by the arms of the level adjustment assembly (4). This set of level adjustment is fixed and articulated on the float (1) by the support chairs (2). The device (3), manual or mechanically assisted, allows the adjustment of the height of the paddle wheel (A) and immersion in the tidal stream depending on the desired action of the current on the blades of the blades (6). ) and the level of the lowest tides.

II permet également de soulever la roue à aube (A) au dessus de l'action des courants de marées ou du flotteur (1) pour la mettre hors service et en permettre la maintenance. La roue à aubes (A) est constituée de deux flasques circulaires (8) supportant les pales (5). Ces flasques ( 8) fig :1 et fig :2 sont fixées sur l'axe (7) et pivotent dans les paliers des bras de l'ensemble de réglage de niveau (4 ). Sur ces flasques (8) sont maintenues par les traverses hautes et basses (5) des pales flexibles, déformables (6) qui sont soumises aux courants de marée. It also makes it possible to lift the impeller (A) above the action of the tidal streams or the float (1) to put it out of service and to allow maintenance. The impeller (A) consists of two circular flanges (8) supporting the blades (5). These flanges (8) fig: 1 and fig: 2 are fixed on the axis (7) and pivot in the bearings of the arms of the level adjustment assembly (4). On these flanges (8) are maintained by the upper and lower rails (5) flexible, deformable blades (6) which are subject to tidal currents.

La force générée par le courant de marée exerce une pression sur les pales des aubes (6) fig :1 ; fig :2 ; fig :3 qui sont réalisées en matériaux flexibles et/ou souples et se déforment en forme de godet chaque fois qu'elles sont soumises à l'action de ces courants fig ; 2 ou fig : 3 . Une fois hors de l'emprise du courant de marée, chaque pale (6) fig :2 ; fig :3 de la roue à aubes (A) quitte sa forme en godet et reprend sa position de repos. L'axe (7) dont le sens de rotation est fonction du sens du courant de marée, transmet la force obtenue par la pression de l'eau sur les godets des pales (6) à tout générateur de pression ou d'intensité y associé. The force generated by the tidal current exerts a pressure on the blades of the blades (6) fig: 1; fig: 2; fig: 3 which are made of flexible and / or flexible materials and deform in the form of cup each time they are subjected to the action of these currents fig; 2 or fig: 3. Once out of the grip of the tidal stream, each blade (6) fig: 2; Fig: 3 of the impeller (A) leaves its bucket shape and resumes its rest position. The axis (7) whose direction of rotation depends on the direction of the tidal stream, transmits the force obtained by the pressure of the water on the buckets of the blades (6) to any pressure or intensity generator associated therewith .
