Title
(EN) WEIR WITH WEIRGATE WITH A LOW PLACED AXIS FORESEEN WITH MECHANICAL DRIVE
(FR) BARRAGE A PORTE A AXE PLACE BAS PREVU AVEC UN ENTRAINEMENT MECANIQUE
Abstract
(EN) The invention concerns a weir with a weirgate with a low placed axis. The weirgate is foreseen with wings in the form of a half circle which carries a tooth-rack. The tooth-rack is driven by gears which are connected with each other by right angle wormgears and via a system of shafts. The system of shafts is led underneath of the weir so when the weirgate is opened, ships can pass the weir.
(FR) L'invention concerne un barrage ayant une porte à axe placé bas. La porte du barrage est prévue avec des ailes en forme de demi-cercle portant une crémaillère. La crémaillère est entraînée par des engrenages lesquels sont reliés les uns aux autres par des vis sans fin à angle droit et par un système d'arbres. Le système d'arbres est mené sous le barrage de manière que lorsque la porte est ouverture, des bateaux peuvent traverser le barrage.
