Abstract

The invention relates to a turbine blade wheel for large water depths, the form of the cross-section of the wheel, comprising blades (4) and consisting of a part (7) that is straight or only slightly curved, being, under no circumstances, at a tangent to the outer circular part of the wheel, said cross-section also consisting of a curved part (8) for connection between parts (7) and (9). Said form, in association with the circular movement of the blades (R) as a result of the rotation of the wheel, follows a circular path of the incoming plane water jet, without hitting the other blades.

Claims

REVENDICATIONS MODIFIÉES  MODIFIED CLAIMS
reçues par le Bureau international le 07 mai 2011 (07.05.2011)  received by the International Bureau on May 07, 2011 (07.05.2011)
1~ Dispositif selon l'invention pour capter l'énergie hydraulique cinétique des hautes chutes d'eau constitué par une turbine composée comme suit : 1 ~ Device according to the invention for capturing the kinetic hydraulic energy of the high waterfalls consisting of a turbine composed as follows:
- d'une partie mobile de forme générale cylindrique avec des aubes (4) supportées par des disques (3)  a movable part of generally cylindrical shape with vanes (4) supported by disks (3)
Caractérisée par la forme cylindrique des aubes dont la section est constituée de trois parties : une partie droite (7) ou de très faible courbure, en aucun cas tangent à la partie circulaire extérieure de la Roue mais faisant avec elle un angle suffisant pour permettre l'entrée, par l'intermédiaire d'un injecteur, d'un jet d'eau plan de section rectangulaire par la totalité de la circonférence extérieure de la roue , une partie en arc de cercle (9) et une partie courbe de liaison entre les parties (7) et (9), l'angle entre l'entrée d'eau dans une aube et sa sortie de la partie circulaire (9), cumul des angles successifs entre les parties (7) (9) et leur liaison est au moins de 180°.  Characterized by the cylindrical shape of the blades whose section consists of three parts: a straight part (7) or very small curvature, in no case tangent to the outer circular part of the wheel but making with it an angle sufficient to allow the input, via an injector, of a plane water jet of rectangular section through the whole of the outer circumference of the wheel, an arcuate part (9) and a curved connecting part between the parts (7) and (9), the angle between the inlet of water in a blade and its exit from the circular part (9), accumulating successive angles between the parts (7) (9) and their connection is at least 180 °.
Cette forme associée au mouvement circulaire des aubes (R), du fait de la rotation de la roue, a pour conséquence, suivant figure 3, une déviation du jet d'eau entrant d'un angle supérieur à 180°, sans aucun choc avec les autres aubes, ce trajet permet la récupération de la totalité de l'énergie cinétique d'un jet d'eau entrant de section rectangulaire qui peut être de toute longueur ce qui permet des débits très importants avec de très hauts rendements.  This shape associated with the circular movement of the blades (R), due to the rotation of the wheel, has the consequence, according to FIG. 3, of a deviation of the water jet entering from an angle greater than 180 °, without any shock with the other blades, this path allows the recovery of all the kinetic energy of an incoming water jet of rectangular section which can be of any length which allows very high flow rates with very high yields.
