Abstract

The devices presently used to control the blades of vertical-axis rotors have a mechanical basis and are connected to the main drive of the rotor. They do not permit flexible adaptation of the setting angle to changed flow conditions. The novel device can change the setting angle characteristic in a variable way. The device for controlling the blades of vertical-axis rotors consists of a separate drive (1) which can change the setting angle of the rotor blades (3) via an appropriate mechanism (2). In order to generate a setting angle characteristic in accordance with the hydrodynamic (fluidic, flow-technical) requirement, the drive is connected to an electronic controlling system (5). The device for controlling the blades of vertical-axis rotors can be used for cycloidal propellers (Voith-Schneider propellers) and paddles of watercraft (vessels), as well as for wind wheels and water turbines with a vertical axis. Representation of the control system attached to the rotor for a rotor blade on the basis of a linear motor. <IMAGE>

Description

Die Erfindung betrifft eine Blattsteuerung für Vertikalachsenrotoren, die dadurch gekennzeichnet ist, daß der Anstellwinkel der einzelnen Blätter durch eine separate, vom Hauptantrieb des Rotors unabhängige Steuerung erfolgt. Dazu wird auf dem Rotor ein elektrischer, pneumatischer oder hydraulischer Antrieb mit einer angepaßten Mechanik zur Steuerung des Blattanstellwinkels angebracht.The invention relates to a sheet control for Vertical axis rotors, which is characterized in that the angle of attack of the individual blades by a separate, control independent of the main drive of the rotor. For this purpose, an electrical, pneumatic or hydraulic drive with adapted mechanics for Control of the blade pitch angle attached.

Die Steuerung kann für Zykloidalpropeller und Schaufelradantriebe von Wasserfahrzeugen, aber auch für Windräder und Wasserturbinen mit vertikaler Achse verwendet werden.The control can be used for cycloidal propellers and Paddle wheel drives for watercraft, but also for Vertical axis wind turbines and water turbines are used become.

Die Rotorblätter sind drehbar gelagert. Während einer Rotor­ umdrehung ändert sich der Anstellwinkel Φ eines Rotorblattes gegenüber der Tangente der Rotorblattbahn.The rotor blades are rotatably supported. During a rotor revolution, the angle of attack Φ of a rotor blade changes opposite the tangent of the rotor blade path.

Durch die Anstellwinkeländerung kann bei Zykloidalpropellern eine resultierende Kraft in Schubrichtung bzw. bei Turbinen ein entsprechendes Drehmoment erzielt werden.The change in the angle of attack for cycloidal propellers a resulting force in the direction of thrust or in turbines a corresponding torque can be achieved.

Es sind verschiedene Steuerungen für Vertikalachsenrotoren entwickelt worden.There are various controls for vertical axis rotors has been developed.

So werden z. B. bei Zykloidalpropellern (Voith-Schneider- Propeller) hydraulische Stellzylinder verwendet (EP 0221491 B63H-1/10), die dann über einen Steuerknüppel den Steuerpunkt verändern. Die Anstellwinkeländerung erfolgt mittels einer mechanischen Kinematik. Die zur Anstellwinkel­ änderung der Rotorblätter notwendige Energie wird über den Hauptantrieb des Rotors zur Verfügung gestellt. Der Anstell­ winkelverlauf ist mit der Lage des Steuerpunktes festgelegt und kann an veränderte Strömungsbedingungen nicht angepaßt werden.So z. B. with cycloidal propellers (Voith-Schneider Propeller) hydraulic actuating cylinder used (EP 0221491 B63H-1/10), which then via a joystick Change control point. The angle of attack changes using mechanical kinematics. The angle of attack Change of the rotor blades necessary energy is over the Main drive of the rotor provided. The employee The course of the angle is determined by the position of the control point and cannot be adapted to changing flow conditions become.

Weiter gibt es zur Veränderung des Anstellwinkels von Vertikalachsenrotoren exzentrische Steuerungen (WO88/10207 B63H1/08). Bei diesen Steuerungen ist die Veränderung des Anstellwinkels an den Kurvenverlauf der Exzenterscheibe gebunden und kann ebenfalls nicht flexibel den jeweiligen Strömungsbedingungen angepaßt werden.There is also to change the angle of attack from Vertical axis rotors eccentric controls (WO88 / 10207 B63H1 / 08). With these controls the Change the angle of attack on the curve of the Eccentric disc is bound and can also not be flexible  be adapted to the respective flow conditions.

Insbesondere kann der Anstellwinkel nicht in Bezug auf den Wirkungsgrad, äußere Belastungen, Kavitationserscheinungen oder Geräuschentwicklungen optimiert werden.In particular, the angle of attack can not be in relation to the Efficiency, external loads, cavitation phenomena or noise developments can be optimized.

Der Erfindung liegt das Problem zugrunde, daß die derzeit zur Anstellwinkelsteuerung von Vertikalachsenrotoren verwendeten Systeme auf mechanischer Basis beruhen und mit dem Haupt­ antrieb direkt gekoppelt sind. Dadurch ist der Verlauf des Anstellwinkels während eines Umlaufes bei festgehaltenem Steuerpunkt N fest vorgegeben und kann nicht flexibel den strömungstechnischen Erfordernissen angepaßt werden. Insbesondere bei Zykloidalpropellern (Voith-Schneider- Propeller) ist zur Änderung der Lage des Steuerpunktes eine aufwendige Mechanik (Steuerknüppel und mechanische Kinematik) erforderlich. Dadurch ergeben sich große Einbauhöhen, die insbesondere bei schiffstechnischen Anwendungen sehr ungünstig sind.The invention is based on the problem that the currently for Angle control of vertical axis rotors used Systems based on mechanics and with the main drive are directly coupled. This is the course of the Angle of attack during one revolution with the Control point N is fixed and cannot be flexible fluidic requirements are adapted. Especially with cycloidal propellers (Voith-Schneider Propeller) is one for changing the position of the control point elaborate mechanics (joysticks and mechanical kinematics) required. This results in large installation heights especially in marine applications are unfavorable.

Erfindungsgemäß wird die Aufgabe durch eine Einrichtung zur Blattsteuerung von Vertikalachsenrotoren gemäß den Merkmalen in den Ansprüchen 1 bis 3 gelöst.According to the invention, the object is achieved by a device for Blade control of vertical axis rotors according to the characteristics solved in claims 1 to 3.

Dadurch, daß auf dem Rotor eine separate Flügelsteuerung angebracht wird, die einen eigenständigen, elektronisch geregelten Antrieb hat und von dem Hauptantrieb des Rotors unabhängig ist, kann eine flexible Anstellwinkeländerung entsprechend den strömungstechnischen Forderungen realisiert werden. Damit kann auch die Einbauhöhe von Vertikalachsen­ rotoren verringert werden.The fact that a separate wing control on the rotor is attached, which is an independent, electronic has regulated drive and from the main drive of the rotor is independent, a flexible angle of attack change realized according to the fluidic requirements become. This also allows the installation height of vertical axes rotors can be reduced.

Die Erfindung wird im folgenden anhand von einem Ausführungs­ beispiel näher erläutert.The invention is based on an embodiment example explained in more detail.
