Description

Windkraftwerk Windkraftwerke der bekannten Bauarten benötigen im Verhältnis zu ihrer Leistung große Flügelräder, weil die Energie des Windes je Quadratmeter Wirkungsfläche nur gering ist. Die großen Flügelräder haben hohe Zentrifugalkräfte zur Folge, und um diese beherrschen zu können, darf die Drehzahl nur verhältnismäßig klein sein. Es entstehen große Drehmomente, die schwere Cretriebe erfordern. Die großen bewegten Massen und die mäßige Bearbeitungsgenauigkeit, die sich bei den großen Dimensionen ergibt, haben beträchtliche Erschütterungen des Windkraftwerkes und der Unterstützungskonstruktion. zur Folge.Wind power plant Wind power plants of the known types require in proportion to their performance large impellers, because the energy of the wind per square meter Effective area is only small. The large impellers have high centrifugal forces as a result, and in order to be able to control this, the speed must only be proportionate be small. There are large torques that require heavy gear drives. the large moving masses and the moderate machining accuracy, which is the results in large dimensions, have considerable vibrations of the wind power plant and the support structure. result.

Alle diese Nachteile werden bei einem Windkraftwerk nach der Erfindung dadurch vermieden oder verringert, daß der Treibwind durch eine Luftdüse aufgefangen und in ihr auf hohe Geschwindigkeit gebracht wird. An der engsten .Stelle der Luftdüse ist das Flügelrad angeordnet, das entsprechend der 'hohen Windgeschwindigkeit mit großer Drehzahl läuft. Die Abluft des Flügelrades gelangt in einen. Diffusor, in dem die Luftgeschwindigkeit verringert und damit der Luftdruck auf den. der Atmosphäre gesteigert wird, so daß kein Luftstau vor der Düse auftritt.All of these drawbacks become apparent in a wind power plant according to the invention this avoids or reduces the fact that the driving wind is caught by an air nozzle and is brought up to high speed in it. At the narrowest point of the air nozzle the impeller is arranged, which corresponds to the 'high wind speed with high speed runs. The exhaust air from the impeller enters a. Diffuser, in which reduces the air speed and thus the air pressure on the. the atmosphere is increased so that no air jam occurs in front of the nozzle.

Die Welle des Flügelrades kann doppelseitig oder einseitig gelagert sein., wobei die Lager in Gondeln untergebracht werden, die zentral in der Luftdüse und dem Diffusor angeordnet sind. In: den Gondeln kann gleichzeitig das Getriebe und ein Elektrogenerator Platz finden.The shaft of the impeller can be mounted on either side or on one side be., the bearings are housed in gondolas that are centrally located in the air nozzle and the diffuser are arranged. In: the gondolas can also use the transmission and find space for an electric generator.

Zur weiteren Verbesserung des Wirkungsgrades können Luftdüse und Diffusor außen mit einer strömungsgünstig ausgebildeten Verkleidung versehen werden, an der die von der Luftdüse nicht erfaßte Luft entlang strömt und auf die am Ende des Diffusors mit verringerter Geschwindigkeit austretende Abluft saugend wirkt. In .dem durch Düse und Diffusor einerseits und Verkleidung andererseits-.gebi,ldeten Hohlraum kann- in einfacher Weise die ganze Versteifungskonstruktion untergebracht werden.Air nozzle and diffuser can be used to further improve efficiency be provided on the outside with a streamlined lining on which the air not detected by the air nozzle flows along and onto that at the end of the diffuser Exhaust air escaping at a reduced speed has a sucking effect. In .dem through jet and diffuser on the one hand and cladding on the other hand-.gebi, ldeten cavity can- the whole stiffening structure can be accommodated in a simple manner.

Vor und hinter dem Flügelrad können Leit- -schaufeln fest oder verstellbar angebracht werden, so daß die Zu- und Abströmung .der Luft des Flügelrades in jede gewünschte Richtung gelenkt werden kann.Guide vanes can be fixed or adjustable in front of and behind the impeller be attached so that the inflow and outflow .der air of the impeller in each desired direction can be steered.

Die Flügel des Flügelrades können von der Hauptwelle aus verstellbar ausgebildet werden, z. B. derart, daß sie in der Flügelachse drehbar sind, und daß dadurch der Zu- und Abströmwinkel der Flügel den jeweiligen Erfordernissen angepaßt werden kann. Diese Flügelverstellung kann z. B. von, einem Fliehkraftregler oder von- anderen Einrichtungen aus automatisch erfolgen. Die Flügelverstellung kann, beispielsweise auch derart sein, daß die Flügel bei Überschreiten des zulässigen Winddrucks in der Art eines Regenschirmes mehr oder weniger nach hinten zusammenklappen.The blades of the impeller can be adjusted from the main shaft be trained, e.g. B. such that they are rotatable in the wing axis, and that as a result, the inflow and outflow angle of the blades is adapted to the respective requirements can be. This wing adjustment can, for. B. of, a governor or be done automatically from other facilities. The sash adjustment can for example, be such that the wings when the permissible limit is exceeded Wind pressure more or less fold backwards in the manner of an umbrella.

Das ganze Aggregat wird zweckmäßig auf einem Bock oder Mast drehbar gelagert, so- daß. -es jeweils in die Windrichtung eingestellt werden 'kann: Dabei kann der Diffusor als Windfahne dienen, so daß die Einstellung selbsttätig erfolgt. Die Einstellung .in Windrichtung kann. auch durch eine besondere Verstelleinrichtung bewirkt oder unterstützt werden, wobei .der Antriebsimpuls von einer besonderen, an beliebiger Stelle angeordneten kleinen Windfahne abgeleitet wird.The whole unit is expediently rotatable on a trestle or mast stored so that. -it can be set in each case in the wind direction: Here the diffuser can serve as a wind vane, so that the setting takes place automatically. The setting in the wind direction can. also through a special adjustment device caused or supported, with .the drive impulse from a special, at any point arranged small wind vane is derived.

Bei Windkraftwerken großer Abmessungen kann -der Hauptdrehzapfen und die Stützstreben -der Gondeln hohl ausgeführt sein, so daß eine Zugänglichkeit aller Lauf- und Verstelleinrichtünggen im Betrieb ermöglicht wird.In the case of wind power plants of large dimensions, the main pivot and the support struts of the gondolas are made hollow, so that everyone is accessible Lauf- and Verstelleinrichtünggen is made possible in operation.

Statt des in der Gondel untergebrachten, von. der Hauptwelle des Flügelrades angetriebenen. Gene- -rators 'kann auch das Flügelrad selbst durch Wicklungen an den Flügelspitzen - als -Generatorrotor dienen, wobei dann die Statorwicklungen gegenüber den ,Flügelspitzen an der engsten Stelle der Düse angeordnet werden. .-Ein Ausführungsbeispiel eines Windkraftwerkes nach .der- Erfindung ist in seinen wesentlichen Einzelteilen in der Zeichnung dargestellt.Instead of the one housed in the gondola, from. the main shaft of the impeller powered. Generators' can also attach the impeller itself by windings the wing tips - serve as a generator rotor, in which case the stator windings opposite the, wing tips are arranged at the narrowest point of the nozzle. .-A Embodiment of a wind power plant according to .der- invention is in its essentials Individual parts shown in the drawing.
