Abstract

L'invention se rapporte au domaine de la production d'énergie hydroélectrique et peut s'utiliser dans un barrage en béton pourvu d'un orifice de décharge destiné à l'évacuation de l'eau avec des débits maximaux ou sous-critiques des crues en cas d'impossibilité de la canaliser dans l'installation hydraulique. L'ouvrage de décharge comprend une paroi de prise d'eau (4) montée dans la zone de collecte des eaux (2). Dans une conduite d'eau de profondeur (5), dans sa zone adjacente à la chambre de turbine (7), on a formé une ouverture (13) dans laquelle on a monté une porte à soupape (14), reliée par charnière à la partie plafond de la chambre (7). Pendant le fonctionnement du dispositif, la porte à soupape (14) en position baissée (en mode d'évacuation des eaux) bloque l'entrée dans la chambre de turbine (7) et empêche les déchets d'y pénétrer. Un faux bord (16) permet de relier l'ouvrage de décharge à un barrage 'flottant' en béton. L'ouvrage de décharge de l'invention se distingue par une fiabilité élevée et par sa simplicité d'utilisation.
