Description
Aus der EP 0 545 280 A 1 ist auch eine Antriebsvorrichtung mit einer auf einer drehbaren Welle fest angeordneten Turbine bekannt, die durch eine Flüssigkeit, insbesondere Wasser beaufschlagbar und zusammen mit der Welle in eine Drehbewegung versetzbar ist, dadurch gekennzeichnet, daß die Welle senkrecht stehend angeordnet ist, daß auf der Welle diese konzentrisch umgebend eine nach obenhin sich konisch erweiternde Röhre fest angeordnet ist und die im oberen Randbereich einen Überlauf mit einem darunter angeordneten, feststehenden Sammelbehälter für überlaufende Flüssigkeit aufweist, und daß die Turbine über wenigstens ein, vom Sammelbehälter ausgehendes Fallrohr von unten mit der Flüssigkeit beaufschlagbar ist.
Die DE 196 47 476 A1 offenbart einen pneumatisch hydraulischen Zentrifugalantrieb für alle Arten der Energiebewegung und Energieerzeugung, dadurch gekennzeichnet, daß durch einen Rotor mit einer oder mehreren integrierten Kammern/Tanks Wasser, Öl oder andere Flüssigkeiten aufnehmen und durch Beschleunigung zentrifugiert/verdichtet und in ein unter Druck stehendes Gehäuse preßt, wobei das Gehäuse, in dem der Rotor angetrieben wird unter Luftdruck oder Gasdruck steht und mit Wasser oder anderen Flüssigkeiten gefüllt ist. Die Kammern des Rotors werden über die Rotorachse mit Flüssigkeit gefüllt und durch die Drehbewegung des Rotors nach außen geschleudert, wodurch Fliehkräfte entstehen, die das Wasser über die an den Kammern angeordneten Düsen aus dem Rotor in das unter Druck stehende Gehäuse schleudern, an dessen Boden sich das Wasser sammelt und einer Turbine zugeführt wird, die das Wasser an einen Energieerzeuger und gleichzeitig in die Rotorachse zurückführt.
Die voranbeschriebenen Lösungen gehen von dem Grundprinzip des Auftriebs einer Wassersäule im Zentrum um eine rotierende Achse aus, von wo aus die Flüssigkeit radial in ein Turbinenrad geführt und durch Fliehkrafte nach außen gedrückt wird, wobei die oben beschriebenen Nachteile auftreten.
Auch die in der WO 00/29747 beschriebene hydraulische Strömungsmaschine kann diese Nachteile nicht beseitigen, da bei dieser Lösung das Wasser dem Saugraum nicht mit einer wannenförmigen Führung zugeführt wird, die Fliehkraft kein Kräftegleichgewicht mit dem atmosphärischen Luftdruck am Ausgang der Drehscheibe bildet und der Motor das Wasser in der Drehscheibe auf Austrittsgeschwindigkeit beschleunigen muß.
Der Erfindung liegt daher die Aufgabe zugrunde, eine hydraulische Strömungsmaschine zu schaffen die, ausschließlich die durch den atmosphärischen Luftdruck bedingte Beschleunigung des Strömungskreislaufes einer in einem Saugraum zu einem Laufrad aufsteigenden Wassersäule nutzt und als Endenergie einem Verbraucher zur Verfügung stellt.
Die Aufgabe wird durch eine hydraulische Strömungsmaschine mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.
Besonders hervorzuheben ist, daß durch eine Öffnung zwischen den beiden inneren Führungswänden vor dem Eingang des Saugraums innerhalb des wannenförmigen Strömungsraums der atmosphärische Luftdruck auf den Wasserspiegel wirken kann und ein zwischen Strömungsraum und Behälter angeordnetes Ausgleichsrohr ermöglicht die Regulierbarkeit des Wasserspiegels im wannenförmigen Strömungsraum. Dabei ist die Höhe des Wasserfüllstandes im Behälter durch bekannte Methoden wie manuell durch ein Sichtfenster oder über entsprechend angeordnete Schwimmer oder über Sensoren, die bei Erreichung eines bestimmbaren Pegels ein Signal auslösen sowie durch ein den Anwendungsbedingungen angepasstes Wasserzulauf- und Wasserablaufsystem optimal bestimmbar. Der atmosphärische Luftdruck übt einen Druck auf den im wannenförmigen Strömungsraum befindlichen Wasserspiegel aus und bewirkt, daß, bedingt durch das vom Laufrad erzeugte Kräftegleichgewicht, das Wasser im Saugraum beschleunigt wird, über die Leitschaufeln in das horizontal um die Achse des Generators rotierende Laufrad und von diesem in den Leitraum geleitet wird, wo es umgelenkt und dem Saugraum wieder zugeführt werden kann.
Dabei addiert sich die Geschwindigkeitsenergie der Austrittsgeschwindigkeit des Wassers aus dem Laufrad mit der Druckenergie des atmosphärischen Luftrucks und durch Querschnittsverengung im Leitschaufelbereich wird das Wasser wieder auf die erforderliche Eintrittsgeschwindigkeit in das Laufrad beschleunigt.
