Beschreibungdescription
Die Erfindung betrifft eine Windkraftanlage zur Nutzbar¬ machung von Windenergie, insbesondere zur Erzeugung von elektrischem Strom sowie zum Antrieb von Versorgungs¬ einrichtungen und Arbeitsmaschinen, gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a wind power plant for utilizing wind energy, in particular for generating electrical current and for driving supply devices and working machines, according to the preamble of patent claim 1.
Ein bekanntes Windkraftturbinenrad (DE-I 925 200) weist einen Rotorkegel auf, von dessen Mantelfläche auf den Umfang verteilte Laufschaufeln radial abstehen. Die Kegel-Basisfläche ist abgeschlossen und die frei abstehenden Schaufeln sind so eng aneinandergerückt, daß sie sich noch überdecken. Bei einer anderen Wind- kraftanlage (DE-A-3 239 087) trägt ein rotierend gelagerter Kegelmantel radial abstehende Schaufel¬ kränze, die sich von der Spitze bis zur Basis des Kegels gegebenenfalls auch in Form von Spiralrippen erstrecken und zudem verhältnismäßig weit radial nach außen abstehen. Zwischen den Spiralrippen sind Luft- k-anäle ausgebildet, die mit Leitblättern spiralförmige Gefäße mit anschließenden Düsen bilden, so daß die aus diesen Kegelkanälen austretende Luft durch die Düsen auf einen feststehenden Rippenkranz aufprallt und dadurch eine Turbowirkung auslöst. Mit diesen bekannten Windrädern lassen sich meist die an ein Windkraftwerk zu stellenden Anforderungen nicht erfüllen. Es soll nämlich bei schwachem Wind bereits eine ausreichende Leistung erreicht werden und zugleich bei starkem Wind kein allzu starker Wirkungsgradabfall eintreten. Die Anlage soll auch wegen überhöhter Drehzahl des Rotors nicht zu Bruch gehen. Schließlich hat sich bei den bekannten Rotoren gezeigt, daß bei Böen ihre Drehzahlen sich sehr stark verändern.A known wind turbine wheel (DE-I 925 200) has a rotor cone, from the circumferential surface of which rotor blades distributed radially protrude. The cone base surface is closed and the freely projecting blades are so close together that they still overlap. In another wind power plant (DE-A-3 239 087), a rotatably mounted cone jacket carries radially projecting blade rings, which optionally extend in the form of spiral ribs from the tip to the base of the cone and also relatively far radially outwards stand out. Air channels are formed between the spiral ribs, which, with guide blades, form spiral vessels with adjoining nozzles, so that the air emerging from these cone channels impacts a fixed ring of ribs through the nozzles and thereby triggers a turbo effect. These known wind turbines usually do not meet the requirements to be placed on a wind power plant. It should namely, sufficient power can already be achieved in weak winds and at the same time there is no excessive drop in efficiency in strong winds. The system should also not break due to excessive rotor speed. Finally, it has been shown in the known rotors that their speeds change very strongly during gusts.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Windkraftanlage zu schaffen, die sowohl bei schwachem als auch bei starkem, böigem Wind eine erhöhte und gleichmäßige Leistung erbringt und außerdem einen einfachen und widerstandsfähigen Aufbau aufweist.The invention is therefore based on the object of providing a wind power plant which produces an increased and uniform output both in weak and in strong, gusty winds and also has a simple and robust construction.
Diese Aufgabe wird an einer Windkraftanlage gemäß dem Oberbegriff des Patentanspruches 1 erfindungsgemäß durch die Kennzeichnungsmerkmale dieses Patentanspruches gelöst.This object is achieved in a wind power plant according to the preamble of claim 1 according to the invention by the characterizing features of this claim.
Vorteilhafte Weiterentwicklungen der Erfindung sind in Unteransprüchen gekennzeichnet.Advantageous further developments of the invention are characterized in the subclaims.
Durch die Abdeckung der radial abstehenden Flügel mit einem Außenmantel entstehen Strömungskanäle für die vom Kegelmantel abgelenkte Windströmung, die mit voller Energie auf die Flügel trifft. Der Außenmantel verhindert dabei ein radiales Abschleudern von Wind¬ strömen mit einer ungünstigen Wirbelbildung. Über die glatte Außenfläche des Außenmantels streicht der Wind wirbelfrei hinweg und erzeugt auf der Rückseite der Flügel einen starken Sog, der wesentlich stärker als der Winddruck ist. Durch die Wirkung als Hohlflügel entsteht an den Flügeln kein Luftstau. Bei starkem Wind wird nur so viel Luft an die Flügel-Kanäle ge- leitet, wie die Öffnungen dieser Hohlflügel aufnehmen, während der überschüssige Wind über den Außenmantel streicht und durch den vorerwähnten Sog den Wirkungs- grad erhöht. Durch die allseits glatten Oberflächen bilden sich keine störenden Wirbel, so daß der Rotor mit relativ hoher Umdrehungszahl laufen kann, ohne daß Schäden auftreten. Hierdurch kann wiederum der Durch- esser des Kegelmantels und des gesamten Rotors ver¬ kleinert werden.By covering the radially projecting blades with an outer jacket, flow channels are created for the wind flow deflected by the cone jacket, which hits the wings with full energy. The outer jacket prevents a radial flinging of wind currents with an unfavorable vortex formation. The wind sweeps across the smooth outer surface of the outer jacket and creates a strong suction on the back of the wing, which is much stronger than the wind pressure. Due to the effect as a hollow wing, there is no air build-up on the wings. In strong winds, only as much air is directed to the wing channels as the openings of these hollow wings receive, while the excess wind sweeps over the outer jacket and, through the aforementioned suction, the effect degrees increased. Due to the smooth surfaces on all sides, no disturbing eddies are formed, so that the rotor can run at a relatively high speed without damage occurring. As a result, the diameter of the cone shell and of the entire rotor can in turn be reduced.
Der Kegelmantel versetzt durch seine Drehbewegung die Luftschicht entlang seiner Fläche in eine gleichsinnige Drehbewegung in Form eines Dralles. Dieser sorgt neben der glatten Bauform für einen wirbelfreien Eintritt der Luftströmung in den Hohlflügel. Daran ändern auch starke Böen nichts, da überschüssige Luftmassen den Rotor nicht angreifen können.Due to its rotary motion, the conical jacket sets the air layer along its surface in a co-rotating motion in the form of a swirl. In addition to the smooth design, this ensures that the air flow does not enter the hollow wing. Even strong gusts do not change this, since excess air masses cannot attack the rotor.
Die Erfindung wird nachfolgend anhand eines Ausführungs¬ beispiels, das auch in der Zeichnung schematisiert dargestellt ist, näher beschrieben. Es zeigen:The invention is described below with reference to an exemplary embodiment, which is also shown schematically in the drawing. Show it:
Fig. 1 eine Seitenansicht einer Windkraftanlage, Fig. 2 eine Stirnansicht eines teilweise ge¬ zeichneten Windrotors und Fig. 3 eine Seitenansicht dieses Windrotors mit eingezeichneten Strömungslinien.1 shows a side view of a wind power plant, FIG. 2 shows an end view of a partially drawn wind rotor, and FIG. 3 shows a side view of this wind rotor with drawn flow lines.
Ein erfindungsgemäßer Windrotor 1 ist auf einem Turm, Gerüst oder Standrohr 2 gelagert, wobei seine im wesentlichen horizontal eingestellte Rotorachse 3 in Achslagern auf einer Drehscheibe (nicht gezeichnet) montiert ist. Dadurch ist der Rotor auf die Windrichtung mittels einer Windfahne 4 selbsttätig oder durch andere mechanische oder automatische Steuerungsein¬ richtungen einstellbar. Von der Rotorachse 3 wird die Rotationsbewegung mittels eines Winkelgetriebes 5 über eine Welle 6, die im hohlen Standrohr gelagert sein kann, nach unten zu einem Bodengetriebe 7, beispiels¬ weise mit einem Zapfwellenanschluß 8, abgeleitet. Eine Kupplung 9 ermöglicht die Trennung des Antriebes. Zweckmäßig ist der Rotor mit Windfahne bis auf den Boden nach unten abklappbar.A wind rotor 1 according to the invention is mounted on a tower, scaffolding or standpipe 2, its rotor axis 3, which is set essentially horizontally, being mounted in axle bearings on a turntable (not shown). As a result, the rotor can be adjusted to the wind direction automatically by means of a wind vane 4 or by other mechanical or automatic control devices. The rotational movement is derived from the rotor axis 3 downwards by means of an angular gear 5 via a shaft 6, which can be mounted in the hollow standpipe, to a ground gear 7, for example with a PTO shaft connection 8. A clutch 9 enables the drive to be disconnected. The rotor with the wind vane can be conveniently folded down to the ground.
Der Windrotor 1 weist einen Kegelmantel 10 auf, der an seiner gegen den Wind gerichteten Spitze 11 geschlossen ist und an seiner Mantelbasis 12 noch einen Windleit¬ ring 13 trägt, dessen Mantelfläche etwa parallel zur Rotorachse ausläuft. Der kegelförmige Rotorkörper ist an seiner Basisfläche offen. Durch den Windleitring werden störende Strömungswirbel weitgehend vermieden. Von der Mantelfläche 10 des Rotors stehen auf den Umfang gleichmäßig verteilte, radial nach außen sich erstreckende Flügel 15 ab, die mit ihrer Innenkante 16 zweckmäßig von der Mantelbasis 12 aus sich in Richtung Kegelspitze 11 erstrecken. Diese Flügel sind zweck¬ mäßig rechteckig, so daß ein die Außenkanten 17 dieser Flügel überdeckender Außenmantel 20 parallel zum Kegel¬ mantel 10 verläuft. Die Länge des Außenmaπtels ist vorteilhaft so groß wie die Erstreckung der mehr oder weniger gekrümmten Flügel entlang einer Mantellinie, * so daß die Flügel in der Mantelebene gesehen vollständig abgedeckt sind. Ein in der Praxis bewährtes Längen- Höhen-Verhältnis der Flügel beträgt etwa 2 : 1. Der Außeπmantel kann wiederum annähernd ein Drittel des Kegelmantels einnehmen. In den auf diese Weise gebil¬ deten Strömungskanälen 21 sind die Flügel aerodynamischen Gesichtspunkten entsprechend angeordnet, wozu sie auch bogenförmig gekrümmt und zur Windströmung in einem Winkel angestellt sein können. Verlaufen die Längskanten 16,17 der Flügel nicht parallel zueinander, so können hierdurch sich erweiternde oder verengende Strömungs¬ kanäle 21 geschaffen werden. Die in Fig.3 angedeuteten Strömungslinien machen sichtbar, daß der zuströmende wind durch den Kegelmantel abgelenkt und durch die Strömungskanäle 21 geführt wird. Durch den Aufprall auf die Flügel wird der Rotor in Drehung versetzt. Ferner wird der abgelenkte Wiπdstrom auch außen über den Außenmantel geleitet, wo an dessen Ende im Innen¬ raum ein Sog entsteht, der die Strömung durch die Strömungskanäle verstärkt. Da der Außenmantel eine sonst übliche Wirbelbildung im 3ereicr. der Flügel verhindert, so kann der Rotor jetzt eine erheblich höhere Drehzahl erreichen. Der strömungstechnisch vor¬ teilhaft ausgebildete Windleitring 13 läßt den durch die Strömungskanäle strömenden Windstrom weitgehend wirbelfrei nach hinten abströmen.The wind rotor 1 has a cone jacket 10, which is closed at its tip 11 directed against the wind and also carries a wind guide ring 13 on its jacket base 12, the jacket surface of which runs approximately parallel to the rotor axis. The conical rotor body is open at its base surface. Disturbing flow vortices are largely avoided by the wind control ring. From the circumferential surface 10 of the rotor project radially outwardly extending vanes 15, which with their inner edge 16 expediently extend from the circumferential base 12 in the direction of the cone tip 11. These wings are expediently rectangular so that an outer jacket 20 covering the outer edges 17 of these wings runs parallel to the cone jacket 10. The length of the outer jacket is advantageously as large as the extent of the more or less curved wings along a jacket line, * so that the wings are completely covered when viewed in the jacket plane. A length-to-height ratio of the vanes that has proven itself in practice is approximately 2: 1. The outer jacket can in turn take up approximately one third of the conical jacket. In the flow channels 21 formed in this way, the wings are arranged according to aerodynamic aspects, for which purpose they can also be curved in an arc and set at an angle to the wind flow. If the longitudinal edges 16, 17 of the wings do not run parallel to one another, widening or narrowing flow channels 21 can be created as a result. The flow lines indicated in FIG. 3 make it clear that the inflowing wind is deflected by the conical jacket and is guided through the flow channels 21. The rotor is rotated by the impact on the blades. Furthermore, the deflected wind current is also conducted outside via the outer jacket, where a suction is created at the end thereof in the interior, which increases the flow through the flow channels. Since the outer sheath usually forms a vortex in the 3ereicr. prevents the wing, the rotor can now reach a significantly higher speed. The flow control ring 13, which is advantageously designed in terms of flow technology, allows the wind flow flowing through the flow channels to flow out to the rear largely without swirls.
Die Windfahne 4 ist um die Horizontalachse drehbar, so daß durch Herausdrehen aus dem Wind ein Stillsetzen des Rotors möglich ist.The wind vane 4 can be rotated about the horizontal axis, so that the rotor can be stopped by unscrewing it from the wind.
Die Erfindung beschränkt sich nicht auf das darge¬ stellte Ausführungsbeispiel. So können die Flügel und der Außenmantel Voll- oder Hohlkörper mit einer strömungs¬ technisch günstigen Querschnittsform sein. Es kann hierbei auch vorteilhaft sein, wenn die Außenfläche des Außenmantels leicnt gewölbt ist, während die Innenfläche plan verläuft. The invention is not limited to the exemplary embodiment shown. Thus, the wings and the outer casing can be solid or hollow bodies with a cross-sectional shape that is favorable in terms of flow. It can also be advantageous here if the outer surface of the outer jacket is slightly curved, while the inner surface is flat.
