Description
Windturbine. Der Gegenstand der vorliegenden Erfindung ist ein Windrad' mit drehbaren Flügeln, die unter Federwirkung im Winde gehalten «-erden.Wind turbine. The subject of the present invention is a wind turbine ' with rotating wings that are held in the wind under the action of springs.
Bei den bekannten Windrädern dieser Art «erden im allgemeinen nur auf die Drehachse wirkende Federn vorgesehen.In the case of the known wind turbines of this type, “generally only ground springs acting on the axis of rotation are provided.
Beim Erfindungsgegenstand werden auch noch die Flügel ann äußersten Ende gegenüber der Drehachse durch Federn gestützt. Die Erfindung isst in den Abb. i bis .t zur Darstellung gebracht.In the subject of the invention, the wings are also outermost End supported by springs opposite the axis of rotation. The invention eats in Fig. i to .t shown.
Die Flügel i des Drehgestel.lies.2 sind auf Achsen 3 schwenkbar befestigt. Der Flügel i ist beim Drehpunkt 3 von einer einerseits .am Drehgestell und @and'erseits am Flügel` selbst befestigten Feder4 gegen einen Anschlag 5 gedrückt. Beim Anlaufen des Windrades würden min die Flügel schon bei normaler Windstärke zurückgedrückt und so das Anlaufen nachteilig beeinflußt werden, zu xvelchem Zweck entgegengesetzt der Feder 4 das Ende des schwingenden Flügels von einer weiteren am Radkranz 2 befestigten Feder 6 gegen den Anschlag 5 gepreßt wird, wodurch. das Pendeln der Flügel vermieden wird. Hinter dem Flügelende ist im Radkranz 2 eine mit einer Nocke 7 versehene Gleitfläche 8 kippbnr gelagert, welche von einer Plattfeder 9 stets in einer Schrägstelftung gehalten «-irl. Bei plötzlich in Pfeilrichtung A eintretenden Windstößen ibt die Feder 6 nach, und der Flügel wird' in Pfeilrichtung B zurückgedrückt, gleitet dabei über die- Fläche 8, wodurch diese in Pfeilrichtung C (Abb.3) gekippt und von der Feder 9 in der andern Schrägstellung (Abb.4) gehalten wird. Der dein Flügelende nachgebende Federschenkel 6 -wird nun von der Platte 8 gesperrt (Abb. 4.). Die Feder 4 bringt nun beim nachlassenden Winde den Flügel wieder gegen den Anschlag 5 zurück, gleitet wieder über die Fläche 8 und stellt sie wieder in Pfeilrichtung D (Abb. ,4) in die Anfangsstellüng zurück, wobei der Federschenkel 6 wieder frei wird und nun wieder hinter das Flügelende greift, wodurch der Fliigel wie am Anfang gegen den Anschlag 5 gedrückt wird.The wings i of the Drehgestel.lies.2 are swivel-mounted on axes 3. The wing i is at the pivot point 3 on the one hand .on the bogie and @ on the other hand on the wing itself attached spring 4 pressed against a stop 5. When starting up of the wind turbine, the blades would be pushed back at normal wind speeds thus adversely affecting tarnishing, for the opposite purpose the spring 4 attached the end of the swinging wing to the wheel rim 2 by another Spring 6 is pressed against the stop 5, whereby. the swing of the wings avoided will. Behind the wing end is a sliding surface provided with a cam 7 in the wheel rim 2 8 kippbnr mounted, which by a flat spring 9 always in an inclined stilt held «-irl. In the event of sudden gusts of wind in the direction of arrow A, the Spring 6 after, and the wing is' pushed back in the direction of arrow B, sliding over the surface 8, whereby this tilted in the direction of arrow C (Fig.3) and from the Spring 9 is held in the other inclined position (Fig.4). The end of your wing yielding spring leg 6 - is now blocked by the plate 8 (Fig. 4.). The feather 4 now brings the sash back against stop 5 when the wind slackens, glides over surface 8 again and sets it back in the direction of arrow D (Fig. , 4) back into the initial position, whereby the spring leg 6 is free again and now reaches behind the wing end again, whereby the wing counteracts as at the beginning the stop 5 is pressed.
