Abstract

The construction contains a rotatably mounted float body arranged to float on a water course so as to enable water to flow into and out of it. The flow of water into the float body causes it to sink. As the float body sinks it reduces the flow cross-section in the water channel. The variation of the flow cross-section is used to maintain a constant upper water level. The float body is raised by allowing water to flow out of its lower region, thus increasing its buoyancy.

Description

Die Erfindung bezieht sich auf eine neuartige Konstruktion zur Absperrung von Wasserläufen zur Nutzung im Wasserkraftwerksbau.The invention relates to a novel construction for shutting off Watercourses for use in hydropower plant construction.

Die bisherigen Konstruktionen von Wehren mit Schützen, Klappen, Schlauchwehren, ect. brauchen eine relativ aufwendige Fundierung und zumeist ein nicht unbeträchtliches Bauwerk oberhalb der Wasserlinie und einen aufwendigen Betätigungsmechanismus zur einwandfreien Funktion, mit den damit nachteilig verbundenen Folgen der Landschaftsästhetik und Kosten für Bau und Betrieb dieser Anlagen.The previous designs of weirs with shooters, flaps, hose weirs, ect. need a relatively complex foundation and mostly not insignificant structure above the waterline and an elaborate Actuating mechanism for proper function, with the disadvantage related consequences of landscape aesthetics and costs for the construction and operation of these Investments.

Bei der Erfindung wird ein einfacher Schwimmkörper (Kasten- od. Rohrkörper), drehbar auf einem Wasserbecken schwimmend gelagert (siehe beiliegende Skizze). Die Regelung des Wasserspiegels erfolgt durch zufließendes Wasser aus dem Staubereich in den Schwimmkörper, welcher dadurch in das Wasserbecken tiefer eintaucht und einen größeren Abflußquerschnitt für das Wasser aus dem Staubereich freigibt.In the invention, a simple floating body (box or tubular body), rotatably supported on a pool of water (see attached sketch). The The water level is regulated by the inflowing water from the storage area into the floating body, which thereby dips deeper into the water basin and releases a larger discharge cross-section for the water from the storage area.

Das Heben des Schwimmkörpers erfolgt durch Ablassen von Wasser aus dem Schwimmkörper (und somit eine Verstärkung des Auftriebes) in den niedrigeren Unterwasserbereich der Wehranlage.The float is lifted by draining water from the Floats (and thus an increase in buoyancy) in the lower ones Underwater area of the weir system.

Die Konstanthaltung des Oberwasserspiegels erfolgt durch das Absenken und Heben des Schwimmkörpers, welches durch die Ansteuerung einer Klappe zum Zufließen von Wasser aus dem Staubereich und Abfließen in den Unterwasserbereich in und aus dem Schwimmkörper bewerkstelligt wird.The upper water level is kept constant by lowering and lifting of the floating body, which is activated by the actuation of a flap for Water from the storage area and draining into and out of the underwater area the floating body is accomplished.

Diese Anordnung kommt somit ohne aufwendige mechanische Antriebselemente zum Heben und Absenken der Absperrung aus.This arrangement is therefore without complex mechanical drive elements Raise and lower the barrier.
