Die Wasserkraftschnecke nach Jank (Europäische Patentanmeldung
Nach Patentanspruch 15 und 16 (
Weiterhin ist die Wasserkraftschnecke insbesondere nach Patentanspruch 6 (
Am Spalt zwischen Trog und Mantelelement besteht eine hohe Quetschgefahr für Fische, da die Fließgeschwindigkeit des Wassers zwischen Trog und Mantelelement relativ groß ist und die Fische deshalb in den Spalt gesaugt werden können.At the gap between trough and shell element there is a high risk of crushing fish, since the flow velocity of the water between the trough and shell element is relatively large and the fish can therefore be sucked into the gap.
Kennzeichnend für herkömmliche Wasserkraftschnecken und insbesondere der Wasserkraftschnecke nach Jank ist der Einsatz von Stahl für die Schneckenflügel. Nach Patentanspruch 2 (
Aufgabe bzw. ZielsetzungTask or objective
Ziel der Erfindung ist die negativen Elemente der Wasserkraftschnecke nach Jank zu eliminieren und so umzukonstruieren, das diese gleichzeitig Kostengünstiger als bisherige Wasserkraftschnecken hergestellt werden können.The aim of the invention is to eliminate the negative elements of the hydraulic screw according to Jank and to redesign so that they can be made at the same time more cost-effective than previous hydropower screws.
Insbesondere sollen die Wirkungsgradverluste durch Transmissionsverluste, die Spaltverluste zwischen Mantelrohr und Trog optimiert werden.In particular, the efficiency losses due to transmission losses, the gap losses between jacket and trough are to be optimized.

Beschreibung der ErfindungDescription of the invention
Die vorliegende Erfindung betrifft die Verwendung von einem oder mehreren Ringgeneratoren (
Kennzeichnend für Wasserkraftschnecken ist die funktionsbedingt niedrige Drehzahl von 20 bis 80 1/min und ein daraus resultierend hohes Drehmoment. Zur Transmission auf die Drehzahl des angeschlossenen Elektro-Generators wurden bisher ein- oder mehrstufige Getriebe verwendet.Characteristic of hydrodynamic screws is the function-related low speed of 20 to 80 1 / min and a resulting high torque. For transmission to the speed of the connected electric generator previously single or multi-stage gearboxes have been used.
Durch die Anwendung von einem oder mehreren mehrpoligen Ringgeneratoren (
Die mechanischen Kräfte aus den Stator-Segmenten (
Vorteil: Auf ein Getriebe zur Transmission der niedrigen Drehzahl der Wasserkraftschnecke (
Vorteil: Gegenüber herkömmlichen Wasserkraftschnecken verfügt die Wasserkraftschnecke (
Vorteil: Durch den Einsatz von mehreren Ringgeneratoren (
Im Zulaufbereich soll im Trog ein Ring bzw. eine Halbschale angeordnet werden, welche den Spalt (
Vorteil: Das gesamte Betriebswasser wird der Wasserkraftschnecke (
Vorteil: Der Spalt (
Vorteil: Durch den abgedeckten Spalt wird das im Wasser mitgeführte Geschiebe direkt der Wasserkraftschnecke (
Vorteil: Die Außenfläche des Mantelrohres (
Durch die Anwendung von einem oder mehreren mehrpoligen Ringgeneratoren (
Vorteil: Das zentrale Versteifungselement kann entfallen bzw. dient nur noch konstruktiven Zwecken.Advantage: The central stiffening element can be omitted or serves only for constructive purposes.
Vorteil: Es werden deutlich längere Wasserkraftschnecken (

Vorteil: Durch die axiale Teilung der einzelnen Schneckensegmente (
Vorteil: Durch den entfallenen Spalt wird eine Quetschgefahr für Fische oder andere Wasserlebewesen vermieden. In Verbindung mit dem Einsatz von form- und kraftschlüssig mit dem Mantelrohr (
