Abstract

La présente invention concerne un procédé et un dispositif de production d'énergie hydroélectrique (100) comprenant une ou plusieurs canalisations d'arrivée (120) perpendiculaires à un écoulement d'eau (110) dans un ruisseau ou une rivière. Les canalisations d'arrivée (120) comportent une pluralité d'ouvertures sur leur longueur. Une conduite d'alimentation (122) et un ensemble turbogénérateur (140) sont interconnectés aux canalisations d'arrivée (120) et à une ou plusieurs canalisations de sortie (160) de sorte que l'élévation de la ou les canalisations de sortie (160) soit inférieure à celle de la ou les canalisations d'arrivée (120). Lorsque l'eau s'écoule dans les canalisations d'arrivée (120), la conduite d'alimentation (122), l'ensemble turbogénérateur (140) et les canalisations de sortie (160), de l'énergie électrique est produite. Le procédé de production d'énergie hydroélectrique selon la présente invention comprend également un dispositif de réduction de pression qui entraîne une réduction de la pression d'eau afin que l'eau puisse être relâchée en toute sécurité dans le ruisseau ou la rivière.
