Abstract

L'invention concerne un dispositif hydroélectrique pour une centrale hydraulique, comprenant au moins une turbine à eau avec un générateur électrique (12 ou 81), qui repose sur une base de support transversale inférieure (8) et comprenant une conduite (10) permettant à la faune aquatique de passer devant la centrale hydraulique. La centrale présente une enceinte (1), une écluse réglable (3), et de part et d'autre de l'enceinte (1), un élément d'espacement (7) respectif, avec des paliers glissants (6) sur des paliers fixes (5), disposés de manière à pouvoir coulisser sur des supports latéraux (5.1 et 5.2) qui sont montés sur la base de support transversale (8). Dans l'enceinte (1) est monté, à rotation, un rotor (2) qui est pourvu d'aubes flexibles (13) montées en rangées sur la périphérie, avec lequel le générateur électrique (12 ou 81) est accouplé mécaniquement et est monté dans celui-ci ou dans l'élément d'espacement (7). Une conduite de passage (10) forme, sur le côté de la centrale hydraulique, à partir de tubes assemblés, un passage approximativement horizontal pour la faune aquatique.
