Description
Die Erfindung betrifft eine Windkraftanlage mit einer drehbar gelagerten Nabe, an der Rotorblätter angelenkt sind, die durch die Windkraft entgegen der Kraft eines Federelements in radialer Richtung verstellt werden können.The The invention relates to a wind turbine with a rotatably mounted Hub, are hinged to the rotor blades, through the Wind force adjusted against the force of a spring element in the radial direction can be.
Eine
solche Windkraftanlage ist aus der
Die radiale Verstellung der Rotorblätter einer Windkraftanlage hat nur wenig Eingang in die Praxis gefunden. Sie ist aber für spezielle Anwendungen durchaus attraktiv. Zu denken ist an Windkraftanlagen von niedriger elektrischer Leistung in einer häufig sturmgepeitschten Umgebung, beispielsweise off-shore Windkraftanlagen zur elektrischen Energieversorgung von Fischfarmen an der Meeresküste.The radial adjustment of the rotor blades of a wind turbine has found little entry into the practice. But she is for special applications quite attractive. To think about wind turbines of low electrical power in a frequently storm-lashed Environment, such as off-shore wind turbines for electrical Energy supply of fish farms at the seashore.
Aufgabe der Erfindung ist es, eine Windkraftanlage der eingangs genannten Art zu schaffen, die unaufwendig im Aufbau, robust, wartungsarm und absolut sturmtauglich ist.task The invention is a wind turbine of the aforementioned To create kind, the unaufaufig in the structure, robust, low-maintenance and is absolutely suitable for the storm.
Bei der diese Aufgabe lösenden Windkraftanlage sitzt auf der Nabe in koaxialer Anordnung ein axial verschiebliches Gleitstück, mit dem ein jedes Rotorblatt über einen Gelenkhebel verbunden ist. Die radiale Verstellbewegung der Rotorblätter ist schwingungsgedämpft.at the task solving wind turbine sits on the Hub in coaxial arrangement an axially displaceable slider, with the one each rotor blade connected via a toggle lever is. The radial adjustment movement of the rotor blades is vibration-damped.
Dank der radialen Verstellbarkeit der Rotorblätter paßt sich die Windangriffsfläche der Windkraftanlage den herrschenden Windverhältnissen selbsttätig an. Die Schwingungsdämpfung der radialen Verstellbewegung wirkt Überreaktionen z. B. beim Einfall einer Bö entgegen.thanks the radial adjustability of the rotor blades fits The wind attack surface of the wind turbine prevailed Wind conditions on automatically. The vibration damping the radial adjustment acts overreactions z. For example Incidence of a gust.
Bei einer bevorzugten Ausführungsform ist die von der radialen Stellbewegung der Rotorblätter abgeleitete axiale Verschiebebewegung des Gleitstücks schwingungsgedämpft.at a preferred embodiment is that of the radial Positioning movement of the rotor blades derived axial displacement movement of the slider vibration damped.
Bei einer bevorzugten Ausführungsform ist ein jeder Gelenkhebel in Längsrichtung ein- und ausfahrbar und in seiner Ein- und Ausfahrbewegung schwingungsgedämpft.at A preferred embodiment is each articulated lever longitudinally extendable and retractable and in its and extension movement vibration damped.
Bei einer bevorzugten Ausführungsform ist das Federelement Teil eines oder mehrerer Federbeine(s) mit einem hydraulischen Teleskop-Schwingungsdämpfer. Geeignete Federbeine sind von Motorrädern her bekannt.at a preferred embodiment is the spring element Part of one or more struts (s) with a hydraulic telescopic vibration damper. Suitable struts are known from motorcycles ago.
Bei einer bevorzugten Ausführungsform greifen an dem Gleitstück mehrere, gleichmäßig über den Umfang verteilte Federbeine an.at a preferred embodiment engage on the slider several, evenly over the circumference distributed struts.
Bei einer bevorzugten Ausführungsform ist ein jeder Gelenkhebel mit einem einzelnen Federbein versehen.at A preferred embodiment is each articulated lever provided with a single strut.
Bei einer bevorzugten Ausführungsform sitzt der Rotor eines elektrischen Generators unmittelbar auf der Nabe der Windkraftanlage. In dieser Konfiguration wird ein optimaler Wirkungsgrad erreicht. Der Rotor des Generators kann aber auch über ein Getriebe mit der Nabe verbunden sein.at In a preferred embodiment, the rotor is seated electric generator directly on the hub of the wind turbine. In this configuration, optimum efficiency is achieved. The rotor of the generator can also have a gearbox be connected to the hub.
