Description

Flügelverstellvorrichtung für Windkraftwerke Die Erfindung bezieht sich auf eine Einrichtung zur Verstellung der Flügel von Windkrafträdern und hat den Zweck, diese Verstellung so rechtzeitig vorzunehmen, daß beim Auftreffen des geänderten Windes auf das Windrad die Flügel schon die richtige ung einnehmen. Erzielt wird dieses dadurch, ß ein den- Verstellimpul.s gebender Windgesch 'ndgkeitsmesser in so großer Entfernung vo dem Windrad auf einem mit dem Kraftradkopf verbundenen Träger angeordnet ist, daß der Wind den Abstand zwischen den Geschwindigkeitsmesser und dem Windrad in derselben Zeit zurücklegt, wie zur Einleitung der Verstellung der Flügel des Windrades benötigt wird.Blade adjustment device for wind power plants The invention relates relies on a device for adjusting the blades of wind turbines and has the purpose of making this adjustment in good time that when the When the wind changes on the wind turbine, the blades are already in the right position. Achieved this is achieved by a wind speed meter giving the adjustment pulse at such a great distance from the wind turbine on one connected to the motorcycle head Carrier is arranged that the wind determines the distance between the speedometer and the wind turbine travels in the same time as to initiate the adjustment the wing of the wind turbine is required.

Es sei erwähnt, daß man früher schon Hilfsvorrichtungen zur Verstellung von Windkraft-,verkteilen .in größerem Abstand von dem Windrad angeordnet hat, und zwar. offenbar in ider Absicht, diese Einrichtungen aus dem Staubereich der Windradnabe usnv. herauszubringen. Auch ,bauliche Rücksichten spielten dabei m@its indem es ,als besonders zweckmäßig erachtet wurde, Hilfswindräder auf dir Achse des Hauptwindrades vorzusehen, wobei sich von selbst die Notwendigkeit ergab, diese Hilfswindräder weit nach vorn zu setzen. Die Möglichkeit, durch einen entsprechend groß gewählten Abstand ,des Impulsgebers die Flügelverstellung so rechtzeitig zu schalten, daß der geänderte Wind schon eine geänderte Flügelstellung vorfindet, ist aber früher noch nicht erkannt und ebensowenig bei den älteren Einrichtungen benutzt.It should be mentioned that there were previously auxiliary devices for adjustment of wind power, verkteilen. Has arranged at a greater distance from the wind turbine, and though. apparently with the intention of removing these facilities from the stowage area of the wind turbine hub usnv. bring out. Also, structural considerations played here by m @ its Auxiliary wind turbines on the axis of the main wind turbine were found to be particularly useful to provide, the necessity arose of its own accord, these auxiliary windmills to put far forward. The possibility of being chosen by a suitably large Distance from the pulse generator to switch the sash adjustment in time that the changed wind already finds a changed wing position, but is earlier not yet recognized and just as little used in the older institutions.

Auf dem Träger des Geschwindigkeitsmessers kann vorteilhaft noch eine Windfahne befestigt werden, die einen Impuls für die Drehung :der Windradachse in die Windrichtung gibt. Diese Anordnung hat einen ähnlichen Vorteil wie vorhin: Die Achse des Windrades hat schon die richtige Lage, wenn der Wind mit geänderter Richtung auf das Rad stößt, und die Windfahne ist selbst dem störenden Einfluß des Windrades und der übrigen Bauteile entzogen. In der Zeichnung ist ein @tisführungsbeispiel der Erfindung schematisch dargestellt.On the support of the speedometer it is advantageous to have one more Wind vane to be attached, which gives an impulse for the rotation: the wind turbine axis in the wind direction gives. This arrangement has a similar advantage as before: The The axis of the wind turbine is already in the correct position when the wind changes direction hits the wheel, and the wind vane itself is the disturbing influence of the wind turbine and removed from the other components. In the drawing is a @ tis guide example of the invention shown schematically.

Es ist z der Turm eines Windkraftwerkes, auf dem sich :der Kraftwerkkopf 2 in bekannter Weise drehen kann. An dem drehbaren Kopf ist die Windradnabe 3 mit den Flügeln 4 gelagert.It is z the tower of a wind power station on which: the power station head 2 can rotate in a known manner. The wind turbine hub 3 is with the rotatable head the wings 4 stored.

Vor der Nabe in einem größeren Abstand, also entgegen -der Windrichtung, liegt am Ende des rohrförmigen Trägers 5 ein Windgeschwindigkeitsmesser 6, der hier als einfache Stauscheite ausgebildet ist. Der angezeigte Wert wird durch an sich bekannte elektrische Übertragungsvorrichtungen auf eine Vorrichtung zur Verstellung der Flügel übertragen. und zwar derart. daß zu jeder Windrichtung eine solche Flügelstellung gehört, die die größtmögliche Leistung erreichen läßt.In front of the hub at a greater distance, i.e. against the wind direction, is at the end of the tubular support 5, a wind speed meter 6, which is here is designed as a simple stowage side. The displayed value is by itself known electrical transmission devices to a device for adjustment the wing transferred. in such a way. that such a wing position for every wind direction belongs, which allows the greatest possible performance to be achieved.

An Stelle einer Stauscheibe können auch andere Geschwindigkeitsmesser verwendet werden.Instead of a baffle plate, other speedometers can also be used be used.

Auf :dem Träger @ befindet sich weiterhin eine Windfahne;, die eine Drehvorrichtung für. den Kopf 2 des Kraftwerkes so beeinflußt, daß die Windradachse stets in die Windrichtung gedreht wird. Die Cbertragungsvorrichtungen hierfür, vornehmlich elektrische Einrichtungen, sind an sich bekannt. Damit das. Tragrohr 5 von der sich drehenden Nabe 3 nicht mit in Drehung versetzt wird. ist es in Lagern drehbar gestützt und durch ein Gewicht 8 belastet, so daß es seine Stellung stets beibehält.There is still a wind vane; on: the carrier @, the one Rotating device for. the head 2 of the power plant influenced so that the wind turbine axis is always turned in the direction of the wind. The transmission devices for this, primarily electrical devices are known per se. So that the. Support tube 5 from the rotating hub 3 is not set in rotation. it is rotatably supported in bearings and loaded by a weight 8 so that it always maintains its position.
