Abstract

Herkömmliche Ring- bzw. Mantelpropeller haben, durch die unbeweglichen Propellerblätter,
keine Vorrichtung zur Steuerung bzw. Regelung des Steigungs- bzw. Anstellwinkels, um einen besseren Wirkungsgrad zu erreichen.
Durch einen Verstellmechanismus, kann ein „Ringpropeller” reguliert werden.
Der Mechanismus befindet sich in Form von einem Kegel(-plan)radgetriebe, zwischen Innen- und Außenhülse eines herkömmlichen Ring- bzw. Mantelpropellers (1).
Zwei unabhängig elektromagnetische Antriebe/Rotoren (2) treiben, verbunden mit jeweils ein Kegel(-plan)rad (3), die Zapfenwellen für die Ringpropellerschaufeln an (4) (5), um eine Regulierung zu ermöglichen.
Um einen konstanten Neigungswinkel der Schaufeln zu gewährleisten, dürfen die Zapfenwellen (4), durch die unabhängigen Antriebe/Rotoren (2), kein Moment an den Ringpropellerschaufeln übertragen.
Dies wird dadurch gewährleistet, dass die Antriebe/Rotoren (2) mit derselben Drehzahl rotieren. Beim Verstellvorgang bewegen sich die beiden Antriebe/Rotoren (2) unabhängig voneinander mit unterschiedlicher Drehzahl. D. h. ein Antrieb/Rotor (2) und damit auch ein Kegel(-plan)rad (3) eilt vor und die Zapfenwellen (4) können dadurch bedingt ein Moment an die Schaufeln (5) übertragen.
Dadurch kann sie als Wasserturbine (Sichone-Turbine) besser auf die jeweilige Wassermenge und Fallhöhe eingestellt werden. Der damit erreichbare Wirkungsgrad von 80 bis 90 Prozent, ähnlich einer Kaplan-Turbine, ermöglicht den Einsatz von nur einem „Ringpropeller” mit Schaufelverstellung, statt mehrerer Propeller-Turbinen.Conventional annular or shell propellers have, by the immovable propeller blades,
no device for controlling the pitch or pitch to achieve better efficiency.
Through an adjustment mechanism, a "ring propeller" can be regulated.
The mechanism is in the form of a cone (Plan) gearbox, between the inner and outer sleeve of a conventional annular or shell propeller (1).
Two independent electromagnetic drives / rotors (2), coupled with each one taper (3), drive the pinion shafts for the ring propeller blades (4) (5) to allow for regulation.
In order to ensure a constant angle of inclination of the blades, the pin shafts (4), by the independent drives / rotors (2), no moment on the ring propeller blades transmitted.
This is ensured by the fact that the drives / rotors (2) rotate at the same speed. During the adjustment process, the two drives / rotors (2) move independently of each other with different speeds. Ie. a drive / rotor (2) and thus also a cone (plan) rad (3) rushes forward and the pin shafts (4) can conditionally transmit a moment to the blades (5).
As a result, it can be set better as a water turbine (Sichone turbine) to the respective amount of water and drop height. The achievable efficiency of 80 to 90 percent, similar to a Kaplan turbine, allows the use of only one "ring propeller" with blade adjustment, instead of multiple propeller turbines.

„Mantel- bzw. Ringpropellersysteme sind dadurch gekennzeichnet, dass der Antrieb über einen Elektromotor erfolgt, der in einer Außenhülle integriert ist. Der ringförmige Rotor nimmt den Propeller auf, wobei die Flügel mit ihrer Außenseite an der Innenseite des Rotorrings starr, also unbeweglich zu einander befestigt sind. Zur Funktion des Ringpropellers ist eine leichtgängige Lagerung zwischen Rotor und Stator erforderlich”.[1]:

Technisches Problem der ErfindungTechnical problem of the invention

Diese Propellersysteme haben durch die starre Anordnung der Propellerblätter/flügel einen geringeren Beaufschlagungsbereich gegenüber Propellersystemen wie z. B. einer Kaplan-Turbine mit einem Verstellmechanismus für die Schaufeln. Diese unbewegliche Anordnung wirkt sich bei Ringpropellern auf den Wirkungsgrad stark aus, da die Drehzahl im möglichen Turbinenbetrieb bzw. der Schub, nicht durch Änderung des Steigungs- bzw. der Anstellwinkels gesteuert bzw. geregelt werden kann.These propeller systems have by the rigid arrangement of the propeller blades / wings a lower loading range against propeller systems such. B. a Kaplan turbine with an adjustment mechanism for the blades. This immovable arrangement has a strong impact on the efficiency of ring propellers, since the speed in the possible turbine operation or the thrust, can not be controlled or regulated by changing the pitch or the pitch.

Bei dem üblichen Aufbau der Ringpropellersysteme befindet sich zwischen Innen- und Außenhülse kein Verstellmechanismus für die Steuerung und Regelung des Steigungs- bzw. der Anstellwinkels.In the usual structure of the Ringpropellersysteme is located between the inner and outer sleeve no adjustment mechanism for the control and regulation of the pitch or the pitch.

Aufgabe der ErfindungObject of the invention

Mit der Erfindung wurde eine Vorrichtung zum Steuern und Regeln der Steigung bzw. des Anstellwinkels von Ringpropellern entwickelt. Die Erfindung dient mit dieser Eigenschaft dazu, den Wirkungsgrad eines Ringpropellers maßgeblich zu verbessern. Weiterhin soll eine strömungsinduzierte Veränderung der Steigungs- bzw. der Anstellwinkel durch Einsatz von Kupplungen (Lastmomentsperren) verhindert werden.The invention has developed a device for controlling and regulating the pitch or angle of attack of ring propellers. The invention serves with this property to significantly improve the efficiency of a ring propeller. Furthermore, a flow-induced change in the pitch or the angle of attack by use of clutches (load torque locks) should be prevented.

Diese Fähigkeiten werden den Merkmale der Patentansprüche gerecht.These capabilities meet the features of the claims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass statt einer Vielzahl von Ringpropellern, vergleichbar wenige effiziente Ringpropeller mit den im Patentanspruch genannten Eigenschaften, unabhängig von den Strömungsbedingungen hergestellt und genutzt werden können.The advantages achieved by the invention are, in particular, that instead of a large number of ring propellers, comparably few efficient ring propellers with the properties mentioned in the claim can be produced and used independently of the flow conditions.

Ausführungsbeispielembodiment

Die Erfindung wird nun mit weiteren Merkmalen und Vorteilen anhand der Beschreibung und Zeichnung von einem Ausführungsbeispiel näher erläutert.The invention will now be explained in more detail with further features and advantages with reference to the description and drawing of an embodiment.

Ausgehend vom Stand der Technik nach 1a/b wird gemäß eines Ausführungsbeispiel der Erfindung, zwischen den Innen- und Außenringe des Ringpropeller ein Getriebe, bestehend aus zwei unabhängig elektromagnetische Antriebe angebracht, die gemeinsam nach 2 den Antrieb der Zapfenwellen für die Ringpropellerschaufeln bilden.Based on the state of the art 1a / b is according to an embodiment of the invention, mounted between the inner and outer rings of the ring propeller, a transmission consisting of two independently electromagnetic actuators, which together after 2 form the drive of the journal shafts for the ring propeller blades.

Dichtungen zwischen den Bohrungen der Innenhülse und den Zapfenwellen, verhindern das Eindringen von Fluid in das Gehäuse.Seals between the holes of the inner sleeve and the journal shafts prevent fluid from entering the housing.

Um einen konstanten Neigungswinkel der Schaufeln zu gewährleisten, dürfen die Zapfenwellen durch die unabhängigen Antriebe/Rotoren bzw. durch die Strömung, kein Moment übertragen. Dies wird dadurch gewährleistet, dass die Rotoren mit derselben Drehzahl nach 3 rotieren.In order to ensure a constant angle of inclination of the blades, the pin shafts are not allowed to transmit any torque by the independent drives / rotors or by the flow. This is ensured by the fact that the rotors at the same speed after 3 rotate.

Desweiteren verhindern in der Innenhülse, nach 5, montierte Kupplungen (Lastmomentsperren), die strömungsinduzierte Verstellung. Furthermore prevent in the inner sleeve, after 5 , mounted couplings (load torque locks), the flow-induced adjustment.

Beim Verstellvorgang, bewegen sich die beiden Rotoren unabhängig voneinander mit unterschiedlichen Winkelgeschwindigkeiten. D. h. ein Rotor eilt vor und die Zapfenwellen können dadurch bedingt nach 4 ein Moment an den Schaufeln übertragen.During the adjustment process, the two rotors move independently at different angular velocities. Ie. a rotor rushes forward and the pin shafts can conditionally after 4 a moment transferred to the blades.
