Abstract

The wheel has a vertical shaft (1) comprising three drive elements that are arranged vertically at an outer circumference, and an airfoil wing-shaped rotor blade (2). The drive elements are connected with a hub (5) that is rotationally supported on the shaft by horizontally arranged props (6). An advanced profile (3) is pointedly or curvilinearly formed in a rotational direction (Z) and open against the rotational direction. The rotor blade projects into the open profile representing a main drive.

Description

Die Erfindung betrifft ein Windrad mit vertikaler Achse.The The invention relates to a wind turbine with a vertical axis.

Windräder mit vertikaler Achse funktionieren entweder als Widerstandsläufer, d. h. die Staudruckdifferenz am Rotorprofil wird für das Erzeugen des Drehmoments genutzt oder als Auftriebsläufer, d. h. der Strömungsdruck erzeugt am Rotorflügel Auftrieb, der das Drehmoment erzeugt.wind turbines with vertical axis work either as resistance runner, d. H. the dynamic pressure difference at the rotor profile is for the Generating the torque used or as a lift rotor, d. H. the flow pressure generated on the rotor blade Buoyancy that generates the torque.

Widerstandsläufer wie sie in DE 10 2004 053 477 A1 oder DE 19939146 A1 beschrieben sind, haftet der Mangel an, daß die Leistungsausbeute des Windes gering ist.Resistance runner as in DE 10 2004 053 477 A1 or DE 19939146 A1 The defect is that the power output of the wind is low.

Auftriebsläufer der Bauform H-Darrieus-Rotor, wie in DE 10 2004 041 281 A1 beschrieben, erreichen eine etwas höhere Leistungsausbeute des Windes, sie ist jedoch geringer wie die bei Windkraftanlagen mit horizontaler Achse.Buoyancy runners of the H-Darrieus rotor type, as in DE 10 2004 041 281 A1 described achieve a slightly higher power output of the wind, but it is less than that of wind turbines with horizontal axis.

Damit Windräder mit vertikaler Achse effektiver arbeiten, gibt es Versuche durch Kombinationen von Widerstandsläufern und Auftriebsläufern wie z. B. in DE 20 2007 008 125 U1 beschrieben, wo im Zentrum des Windrades Rotorblätter angeordnet sind, die das Widerstandsprinzip nutzen und am Außendurchmesser des Windrades sind Tragflügel vertikal angeordnet, deren Auftrieb aus Windrichtung und Drehbewegung Vortrieb erzeugen. Auch diesen Lösungen haftet der Nachteil an, daß der Widerstandsläufer, im Zentrum angeordnet, zwar eine hohe Drehzahl erzeugen will, die aber der Drehzahl, der am äußeren Durchmesser angeordneten Tragflügel, nicht entspricht, wodurch die Leistungssteigerung durch den innenliegenden Widerstandsläufer unbedeutend ist.In order for wind turbines to work more effectively with vertical axis, there are attempts by combinations of resistance runners and buoyancy runners such. In DE 20 2007 008 125 U1 described where rotor blades are arranged in the center of the wind turbine, which use the principle of resistance and the outside diameter of the wind turbine are vertically arranged wings whose lift from the wind direction and rotary motion generate propulsion. These solutions also has the disadvantage that the resistance rotor, arranged in the center, although wants to generate a high speed, but the speed, the arranged on the outer diameter of the wing, does not match, whereby the performance increase by the inner resistance rotor is insignificant.

Deshalb ist bei dieser Kombination die Leistungsausbeute bei niedrigen Windgeschwindigkeiten nur unbedeutend höher.Therefore In this combination, the power output at low wind speeds is only insignificantly higher.

Bei allen bisher beschriebenen H-Darrieus-Rotoren werden die Rotorblätter mit der Nabe des Windrades durch diagonale Streben verbunden, die bei Rotation den Wind so verwirbeln, daß die Auftriebskraft sinkt und die mögliche Leistungsausbeute nicht erreicht wird.at All previously described H-Darrieus rotors become the rotor blades connected to the hub of the windmill by diagonal struts that during rotation, the wind swirl so that the buoyancy force decreases and does not reach the possible power output becomes.

Der Erfindung liegt das Problem zu Grunde, ein um eine vertikale Achse rotierendes Windrad bzw. seine Antriebselemente bzw. Rotorblätter so auszubilden, daß sie in der Lage sind, sowohl den Staudruck des Windes als auch die Strömungsenergie des Windes in eine möglichst große Leistung – Produkt aus Drehmoment und Drehzahl – umzuwandeln, wobei die notwendigen Streben zwischen Nabe und Antriebselementen die Energieumwandlung des Windes in Rotationsenergie des Windesrades nicht stören, sondern unterstützen.Of the Invention is based on the problem, one around a vertical axis rotating wind turbine or its drive elements or rotor blades train so that they are able to both the dynamic pressure of the wind as well as the flow energy of the wind in the highest possible performance - product from torque and speed - to convert, with the necessary Struts between hub and drive elements energy conversion of the wind in rotation energy of the wind wheel do not disturb but support.

Erfindungsgemäß wird das gelöst, indem die auf dem Außendurchmesser D angeordneten Rotorblätter, zwei- oder einteilig so ausgebildet sind, daß jedes Rotorblatt bei einer Umdrehung über 2 × 120° durch die Auftriebskraft aus der Windgeschwindigkeit getrieben wird und zusätzlich über ca. 150° durch die Staudruckdifferenz des Windes getrieben wird, weil sowohl Rotorblätter als auch die Verstrebung zwischen Rotorblättern und Nabe so ausgebildet sind, daß sie in Windrichtung große Cw-Werte und gegen den Wind kleine Cw-Werte haben.This is achieved by the arranged on the outer diameter D rotor blades, two- or integrally formed so that each rotor blade is driven in one revolution over 2 × 120 ° by the buoyancy force from the wind speed and additionally about 150 ° through the Dynamic pressure difference of the wind is driven, because both rotor blades and the strut between the rotor blades and hub are designed so that they have large C w values in the wind direction and small C w values against the wind.

Bei den zweiteiligen Antriebselementen, bestehend aus gleichlangem Rotorblatt und vorgesetztem Profil, geschieht diese Ausbildung, indem sie durch ein in Drehrichtung vorgesetztes spitz oder kurvenförmig gebogenes und nach hinten offenes Profil zu einem zweiteiligen Antriebselement ergänzt werden oder indem bei den einteiligen Rotorblättern diese als gekrümmte Profilrotorblätter ausgebildet sind und in Drehrichtung ein, nach innen oder außen angearbeitetes spitzes oder kurvenförmiges, Profil haben, das entgegen der Drehrichtung offen ist.at the two-piece drive elements, consisting of the same length rotor blade and superior profile, this training happens by going through a pointed in the direction of rotation or curved curved and open back profile to a two-piece drive element be supplemented or by the one-piece rotor blades this formed as a curved profile rotor blades are and in the direction of rotation, worked inwards or outwards pointed or curved, have profile that counter the direction of rotation is open.

Bei den Verstrebungen zwischen Antriebselementen bzw. Rotorblättern und Nabe geschieht diese Ausbildung, indem diese horizontal angeordnet und in Drehrichtung spitz oder kurvenförmig ausgeformt sind und gegen diese stumpf oder offen sind.at the struts between drive elements or rotor blades and hub this training is done by placing these horizontally and are formed in the direction of rotation pointed or curved and against these are dull or open.
