Title
(EN) WATER HANDLING MEANS
(FR) DISPOSITIF DE DISTRIBUTION D'EAU
Abstract
(EN)
A water lifting machine has multiple facets which make it practical for use in rural and special applications. These facets include a frame on which a circular ring and a water tank are mounted in a manner in which the frame can be tipped on its side and the ring and tank then serve as wheels for transport of the machine. They also include a head which is rotated on a central conduit to lift water and has preferably downwardly or upwardly and outwardly extending arms with outlets which discharge into the ring around them, the outlets being provided with closure means openable by centrifugal effect. The arms and conduit form a siphon effect in the machine as long as there is sufficient pressure at the outlets to keep the closure means open. Drive train options allow effective application of human power for lifting water including one or two persons pedaling or two persons cranking. Options for leading the lifted water into drums or containers are provided.

L'invention se rapporte à un équipement élévateur d'eau comportant de multiples facettes qui en font un dispositif utile tant dans des applications rurales que spéciales. Cet équipement comporte un châssis sur lequel sont montés un anneau circulaire et un réservoir à eau de sorte que le châssis peut basculer sur le côté et que l'anneau et le réservoir servent alors de roues pour le transport dudit équipement. Ce dernier peut également comporter une tête qui est susceptible de pivoter sur un conduit central de manière à élever l'eau et présente de préférence des bras se prolongeant vers l'extérieur, vers le haut ou vers le bas, et possédant sur leur pourtour des orifices de sortie débouchant dans l'anneau, lesdits orifices de sortie étant pourvus d'organes de fermeture susceptibles de s'ouvrir sous l'effet de la force centrifuge. Les bras et le conduit produisent un effet siphon dans ledit équipement tant qu'il existe une pression suffisante au niveau des orifices de sortie pour maintenir ouverts les organes de fermeture. Des options à train d'entraînement permettent l'utilisation de la force humaine pour élever l'eau, par le biais notamment d'une ou de deux personnes qui pédalent ou de deux personnes manoeuvrant une manivelle. L'invention se rapporte également à des options permettant le transfert de l'eau extraite dans des tambours ou des containers.
