Abstract

The wind turbine has a two-armed mast (4), which can pivot in a vertical direction about its rotational axis. One arm of the mast carries the turbine wheel (6), the other arm carrying a counter-weight, with two vertical wind vanes (7) behind the turbine wheel (6), also serving to guide the wind currents. Pref. the mast (4) is angled at 45 degrees to the horizontal in its working position and it is attached to the top of a support pylon (1) via a rotary bearing (2. 3). It pivots through 90 degrees into the stowed position under control of a hydraulic cylinder (8).

Description

Windkraftanlage Bei den Windkraftanlagen mit einem schw@nkbaren Mast erfolgt das in den Wind drehen durch eine Windfahne, die durch oln Gestänge an einem Drehteller befestigt ist. Das Auf- und Abschwenken der Fahne erfolgt hier mittels eines Zugseiles, das mit dem schwenkbaren Mast verbunden ist. Bei der neuen Ausführung wird das in den Wind drehen durch am Mast befindliche Windleitflächen bewirkt.Wind power plant For wind power plants with a swiveling mast turning into the wind is done by a wind vane, which is attached to one by oln rods Turntable is attached. The flag is swiveled up and down here by means of a pull rope that is connected to the pivoting mast. With the new version turning into the wind is caused by wind deflectors on the mast.

Die Abbn, 1 und 2 zeigen den Erfindungsgegenstand in beispiels weiser Ausfährung. f Auf einem Turn 1 befindet sich ein Drehbock 2, er sich um eine Königssäule 3 in horizontaler Richtung dreht.Figs. 1 and 2 show the subject invention in example wise Execution. f On a turn 1 there is a turning stand 2, he is around a king column 3 rotates in the horizontal direction.

Der Mast 4 ist in der Betriebsstellung um ca. 45° nach oben gerichtet. Er trägt an seinem um 45° abgeschrägten Kopf den Maschinenträger 5 nebst Luftschraube 6. Vor der tuftschraube 6 (gesehen vom Turn aus) befinden sich zwei Leitflächen 7, die mit Mast 4 und Maschinenträger 5 fast verbunden sind. Sie dienen zur Windführung und sind, um den Strömungsdrall auszunutzen, an der Luftschraubenseite leicht gekrümmt. Dadurch wird eine Wirkungsgradverbesserung bis zu 9 % erreicht. Diese Leitflächen 7 ersetzen gleichzeitig die Windfahne. Das Herabschwenken auf den Erdboden erfolgt hydraulisch durch den Zylinder 3, wobei der Schwenkbereich ca. 900 beträgt. Auf der Erde kommt die Stirnfläche der Luftschraube 6 in dem Windschatten des Mastes 4 zu liegen, so daß diese vor Stürmen gesichert ist.In the operating position, the mast 4 is directed upwards by approx. 45 °. On its head, which is bevelled at 45 °, it carries the machine carrier 5 together with the propeller 6. In front of the propeller 6 (seen from the turn) there are two guide surfaces 7, which are almost connected to mast 4 and machine carrier 5. They serve to guide the wind and, in order to take advantage of the flow swirl, are slightly curved on the propeller side. This results in an efficiency improvement of up to 9%. These baffles 7 also replace the wind vane. The swing down to the ground takes place hydraulically through the cylinder 3, the pivoting range being approx. 900. on the face of the propeller 6 comes in the slipstream of the mast 4 to lie so that it is secured from storms.
