Abstract

A rotor carrier rotating horizontally on a base platform with roller bearings has four to sixteen upward folding vertical (3) and horizontal (4) segments to form a block on reaching a vertical position. A generator produces electric power fed by other devices into the closest authorized mains supply.

Description

Auf einer Plattform (Fundament) bewegt sich auf Rollenlagern (wie bei Planetarien und Radioteleskopen) der Rotorenträger der Windkraftanlage, der gegenüber der Plattform unbegrenzt verdrehbar ist und durch eine vertikale Stabilisierungsplatte jede Abweichung der Windrichtung ohne Zeitverzögerung auf die Arbeitsrichtung der Anlage (90° quer zur Windrichtung) überträgt. Je nach der gewünschten Antriebsseite (rechts oder links vom Drehpunkt) erzeugt eine angemessene Krümmung der Stabilisierungsplatte (nach links bei Rechtsantrieb oder nach rechts bei Linksantrieb) den erforderlichen Gegendruck zum Ausgleich der einseitigen Windeinwirkung ohne daß hierfür elektronisch gesteuerte. Elektromotoren benötigt werden.Moved on a platform (foundation) on roller bearings (like planetariums and radio telescopes) the rotor carrier the wind turbine opposite the platform can be rotated indefinitely and by a vertical Stabilizing plate on any deviation of the wind direction without time delay transfers the working direction of the system (90 ° across the wind direction). Depending on the desired drive side (right or left of the fulcrum) creates an appropriate curvature of the Stabilizing plate (to the left with right-hand drive or to the right with left-hand drive) the necessary counter pressure to compensate for the unilateral wind exposure without electronically controlled. Electric motors needed become.

Für die erforderliche leichtgängige Verdrehbarkeit des Rotorenträgers gegenüber der Rotorenplattform bietet sich ebenfalls eine stabile und leichtgängige Rollenlagerung an.For the required smooth Rotatability of the rotor carrier across from the rotor platform also offers stable and smooth-running roller bearings on.

Die Arbeitsweise der Windkraftanlage mit Horizontalrotor beruht darauf, daß der Wind nebeneinanderliegende um 90° aufklappbare Segmente auf der Antriebsseite zur Rotation um ihre vertikale Achse zwingt und beim Rücklauf wieder in ihre Ausgangsposition (Flachlage) zurückversetzt. Da diese Positionsveränderung der Antriebssegmente nicht spontan abgeschlossen werden kann ergibt sich zwangsläufig eine Verminderung des theoretischen Wirkungsgrades, der mit steigender Rotationsanzahl pro Zeiteinheit abnimmt. Da im Falle von Windanlagen mit dreiflügeligem Vertikalrotor zwar der der gesamte von den Flügeln bestrichene Kreis Einwirkungsfläche des Windes ist, in diesem Zusammenhang jedoch nur jene Flächen zählen, die gleichzeitig dem Winde ausgesetzt sind (etwa 7 bis 10% der erfaßten Fläche) ergibt sich unter Berücksichtigung von angenommenen 25 % Verminderung des Wirkungsgrades aufgrund der Verzögerung bei der Positionsveränderung für die beschriebene Windkraftanlage mit Horizontalrotor ein Wirkungsgrad von 37,5% der vom Winde erfaßten Fläche, also mehr als das Vierfache des Wirkungsgrads von Vertikalrotor-Anlagen der zur Zeit eingesetzten Art.How the wind turbine works with horizontal rotor is based on the fact that the wind lies side by side segments that can be opened by 90 ° on the drive side Forces rotation around its vertical axis and when rewinding again returned to their starting position (flat position). Because this change in position the drive segments cannot be completed spontaneously results inevitably a decrease in theoretical efficiency, which increases with increasing The number of rotations per unit of time decreases. Because in the case of wind turbines with three-winged The vertical rotor admittedly covers the entire area of action of the wings which is swept by the wings In this context, wind is only those areas that count exposed to the wind at the same time (about 7 to 10% of the area covered) yourself considering of an assumed 25% reduction in efficiency due to the delay when changing position for the Wind turbine with horizontal rotor described an efficiency 37.5% of those caught by the wind Area, that is more than four times the efficiency of vertical rotor systems Art currently used.

Die optimale Anzahl der Rotor-Segmente dürfte je nach Größe der Anlage bei 8 bis 16 liegen. Rotoren mit 8 Segmenten haben aufgrund des größeren Abstands zwischen den Klappflügeln einen höheren Wirkungsgrad, Rotoren mit 16 Segmenten laufen gleichmäßiger aufgrund geringerer Drehzahlschwankungen.The optimal number of rotor segments should ever according to the size of the system are 8 to 16. Rotors with 8 segments have due to the greater distance between the folding wings a higher one Efficiency, rotors with 16 segments run more evenly due to lower speed fluctuations.

Die niedrigere Bauhöhe der Horizontalrotor-Anlage ist vorteilhaft im Hinblick auf die Stabilität, wirkt sich aber insofern negativ aus als die Windgeschwindigkeit in Bodennähe niedriger ist als in 80 m Höhe. Bei gezielter Auswahl des Aufstellungsgeländes (Bergkuppen und flache Hänge, die Gruppenbauweise ähnlich wie bei Terrassenhäusern zulassen) läßt sich dieser Nachteil jedoch deutlich begrenzen. Eine Horizontalrotor-Anlage auf einen hohen Mast zu stellen, um höhere Windgeschwindigkeiten nutzen zu können,erscheint nicht empfehlenswert aufgrund der in diesem Falle nicht auszuschließenden Stabilitäts- und Torsionsprobleme.The lower overall height of the horizontal rotor system is advantageous in terms of stability, but has an effect negative than the wind speed lower near the ground is as at 80 m height. With a targeted selection of the installation site (mountain tops and flat slopes, the group construction is similar like with terrace houses allow) can however, this disadvantage is clearly limited. A horizontal rotor system on one to put high mast to higher Being able to use wind speeds does not seem recommendable due to the stability and Torsion problems.

Zwei übereinanderliegende Horizontalrotoranlagen mit unterschiedlichen Antriebshälften und einem planflächigen Richtungsstabilisator stellen im Hinblick auf Richtungsstabilität die optimale Konstruktionsvariante dar.Two superimposed horizontal rotor systems with different drive halves and a flat Directional stabilizers provide the optimal in terms of directional stability Construction variant.
