Title
(EN) SLUICE WITH AUTOMATIC GATE
(FR) ECLUSE A PORTE D'AMONT AUTOMATIQUE
Abstract
(EN)
The invention concerns an under opening automatic sluice with a cylinder shaped gate (1) tilting around a horizontal axis which is positioned in the centre of the shaft (3). The size of the opening of the gate is controlled by one or more floating counterweight(s) (17) which is (are) positioned in (a) housing(s) (18) and which is (are) in open connection with the upper or lower water level. Because the centre of gravity of the gate (1) changes place horizontally with the gate movement, it is possible to maintain a preadjusted level. By adjustment of the bow-formed cylinder wall (2) with respect to shaft (3) it is possible to influence the operation characteristic of the gate.
(FR)
L'invention concerne une écluse automatique qui s'ouvre depuis le bas et qui comprend une porte d'amont de forme cylindrique (1) basculant autour d'un axe horizontal situé au centre de l'arbre (3). Les dimensions de l'ouverture de la porte sont réglées par un ou plusieurs contrepoids flottant(s) (17) qui est (sont) disposé(s) dans un (des) châssis (18) et qui est (sont) en connexion ouverte avec le niveau supérieur ou inférieur de l'eau. Puisque le centre de gravité de la porte (1) se déplace horizontalement en fonction du mouvement de la porte, il est possible de maintenir un niveau préréglé. En réglant la paroi courbée (2) du cylindre par rapport à l'arbre (3) il est possible d'agir sur les caractéristiques de fonctionnement de la porte.
