Abstract

L'invention concerne une porte à ouverture et à fermeture actionnées par gravité, commandée par le niveau de l'eau. Dans une chambre d'écluse (1), un battant de porte (26), un dispositif d'ouverture et de fermeture, des installations d'alimentation et un dispositif de commande sont reliés mécaniquement entre eux. Le battant (26) est relié à la chambre d'écluse (1) par des chaînes de drague transversales (22, 23). Le battant (26) est relié à un arbre de rotation (17) avec un moment positif d'un câble en acier vertical (16). Un réservoir d'eau (20) est relié à l'arbre de rotation (17) avec un moment négatif d'un autre câble en acier vertical (18). Le réservoir d'eau (20) est relié à un dispositif d'alimentation en eau par l'intermédiaire de tuyaux souples (39). Le dispositif d'alimentation en eau commande l'alimentation de l'eau par le niveau d'eau et un commutateur à flotteur (31, 31'). Le niveau d'eau commande automatiquement le stockage et le déchargement d'eau dans le réservoir d'eau (20), et, par conséquent, le niveau d'eau commande automatiquement la montée et la descente du réservoir d'eau (20), et par conséquent, l'ouverture et la fermeture du battant (26).
