Description
Die vorliegende Erfindung betrifft eine Windkraftmaschine.The The present invention relates to a wind power machine.
Windkraftmaschinen sind bekannt und sind heute als horizontal rotierende Windräder bereits vielfach im Einsatz. Die horizontal rotierenden Windräder weisen zwar bereits einen beachtlichen Wirkungsgrad, aber auch die bekannten Nachteile wie z. B. große Bauhöhe, Geräuschentwicklung, Notwendigkeit zur Nachführung, starke mechanische Belastung der Bauteile durch Fliehkräfte und Vibrationen auf. Die mechanischen Belastungen treten insbesondere auch dann auf, wenn das Windrad notwendigerweise in den Wind gedreht werden muß. Außerdem benötigen die bekannten Anlagen entweder eine relativ hohe Anfangswindgeschwindigkeit oder müssen anfangs durch Hilfsmotoren in Rotation versetzt werden.Wind power machines are known and are already widely used today as horizontally rotating wind turbines in use. The horizontally rotating wind turbines already have one considerable efficiency, but also the known disadvantages such as z. B. large height, Noise, Need for tracking, strong mechanical stress on the components due to centrifugal forces and Vibrations on. The mechanical loads occur in particular even if the windmill necessarily turned into the wind must become. In addition, the need known systems either a relatively high initial wind speed or at first be rotated by auxiliary motors in rotation.
Aus
diesem Grunde sind vertikal rotierende Windräder, d. h. Windräder mit
vertikaler Achse, konzipiert worden, die diese Nachteile beseitigen
sollen (vgl.
Ein anderer Ansatz sieht vor, die Rotorblätter in mehrere Teilblätter zu unterteilen (vgl. WO 88/09873 A1). Das unterteilte Profil setzt dabei dem Wind bei der Rücktour einen geringeren Widerstand entgegen. Trotz dieser Maßnahme weisen jedoch derartige Windkraftmaschinen nur einen bescheidenen Wirkungsgrad auf.One another approach provides for the rotor blades in several parts of the sheets subdivide (see WO 88/09873 A1). The subdivided profile sets with the wind on the return trip a lower resistance. Despite this measure However, such wind turbines only a modest efficiency on.
Es ist demzufolge Aufgabe der vorliegenden Erfindung, unter Vermeidung der aus dem Stand der Technik bekannten Nachteile eine Windkraftmaschine mit einem um eine vertikale Achse drehbaren Rotor zu schaffen, die einen hohen Wirkungsgrad aufweist sowie leicht und preiswert herstellbar ist.It is therefore an object of the present invention, while avoiding the disadvantages known from the prior art a wind turbine with a rotatable about a vertical axis rotor to provide has a high efficiency and easy and inexpensive to produce is.
Diese Aufgabe wird erfindungsgemäß durch eine Windkraftmaschine mit einem um eine vertikale Achse drehbaren Rotor, mit mindestens drei im wesentlichen radial angeordneten Rotorblättern, die den Rotor in gleich große Sektoren unterteilen, wobei die Rotorblätter in jeweils mehrere nach dem Widerstandsprinzip arbeitende Teilblätter unterteilt sind, und wobei zwischen den Teilblättern vertikale Spalte zum Durchtritt der Luft angeordnet sind, gelöst, die gekennzeichnet ist durch zwischen den Teilblättern verlaufende konvergente Kanäle, wobei die Teilblätter während der Hintour als Widerstandsläufer oder Auftriebsläufer und während der Rücktour als Auftriebsläufer wirkend ausgebildet sind.These The object is achieved by a Wind power machine with a rotor rotatable about a vertical axis, with at least three substantially radially arranged rotor blades, the the rotor in equal size Divide sectors, the rotor blades in each case after several dividing blades operating according to the resistance principle are subdivided, and wherein between the part sheets vertical column are arranged for the passage of the air, dissolved, marked is due to running between the sub-leaves convergent channels, the part sheets while the back tour as resistance runner or buoyancy runner and while the return tour as a buoyancy runner are formed acting.
Wenn die Teilblätter der Windkraftmaschine derart optimiert werden, dass ihr strömungstechnischer Widerstand oder ihr strömungstechnischer Auftrieb bei der Hintour maximiert und ihr strömungstechnischer Widerstand bei der Rücktour minimiert bzw. der Auftrieb maximiert sind, lassen sich gegenüber konventionellen Vertikalrotoren erhebliche Wirkungsgradverbesserungen erzielen. Besonderer Bedeutung kommen dabei den zwischen den Teilblättern verlaufende konvergenten Kanälen zu. Hierdurch wird bewirkt, dass die sich beschleunigende Strömung nicht abreißt und es nicht zu Verwirbelungen mit Energieverlust kommt. Weiterhin sind somit höhere Anstellwinkel möglich, die einen größeren Auftrieb bewirken.If the part sheets the wind turbine are optimized so that their fluidic Resistance or their fluidic buoyancy maximized at the back and their fluidic resistance on the return trip minimized or the buoyancy are maximized, can be compared to conventional Vertical rotors achieve significant efficiency improvements. Particular importance is attached to running between the sub-leaves convergent channels to. This causes the accelerating flow is not tearing off and there is no turbulence with energy loss. Farther are thus higher Pitch possible, the greater buoyancy cause.
Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.advantageous Embodiments are the subject of the dependent claims.
Vorteilhafterweise beträgt das Kontraktionsverhältnis der konvergenten Kanäle 0,6 bis 0,8.advantageously, is the contraction ratio the convergent channels 0.6 to 0.8.
Die konvergente Kanalführung wird bevorzugt durch die Profilierung der Teilblätter erzeugt.The convergent ducting is preferably generated by the profiling of the partial sheets.
Es ist jedoch auch möglich, die konvergente Kanalführung durch eine Verstellung der Teilblätter während eines Umlaufs zu erzeugen. Dies setzt jedoch eine vergleichsweise aufwendige mechanische Lösung z. B. mit Schrittmotoren voraus.It but it is also possible the convergent ducting to produce by an adjustment of the sub-sheets during a circulation. However, this is a comparatively complicated mechanical solution z. B. with stepper motors ahead.
Das Kontraktionsverhältnis muß nicht über den gesamten Kanal konstant sein, sondern kann in einem hinteren Kanalabschnitt größer sein als in einem vorderen Kanalabschnitt. Hierdurch wird wiederum die Beschleunigung der Strömung gezielt dort beeinflußt, wo die Gefahr von Ablösungen am größten ist.The contraction ratio need not be constant over the entire channel, but may be greater in a rear channel section than in a front channel section. As a result, in turn, the acceleration of the flow will be targeted there be influences where the risk of detachment is greatest.
Die in radialer Richtung benachbarten Teilblätter weisen nach einer bevorzugten Ausführungsform gleiche Abstände zueinander auf.The in the radial direction adjacent partial sheets have a preferred embodiment same distances to each other.
Soweit unter Berücksichtigung aller weiteren Parameter wie Profilierung, Zahl der Teilblätter etc. strömungstechnisch günstig, können die in radialer Richtung benachbarten Teilblätter auch unterschiedliche Abstände zueinander aufweisen.So far considering all other parameters such as profiling, number of part sheets, etc. aerodynamically Cheap, can the radially adjacent parts of the leaves also different distances to each other.
Gleiches gilt für die Profilierung der Teilblätter, die bei allen Teilblättern gleich oder unterschiedlich ausgebildet sein kann. Aus Symmetriegründen sollten jedoch nur die Teilblätter jedes. Sektors und nicht die in Umfangsrichtung verteilten Teilblätter unterschiedliche Profilierungen aufweisen, da es ansonsten zu Unwuchten kommt.The same applies to the profiling of the partial sheets, the with all partial sheets may be the same or different. For reasons of symmetry should but only the part sheets each. Sector and not the circumferentially distributed partial leaves Profiling, otherwise it comes to imbalances.
Auch die konvergenten Kanäle können entweder alle gleich oder innerhalb eines Sektors unterschiedlich ausgebildet sein.Also the convergent channels can either all the same or different within a sector be educated.
Vorteilhaft ist schließlich, wenn das Profil der Teilblätter eine konvexe Unterseite aufweist.Advantageous is finally, if the profile of the part sheets has a convex bottom.
Vorteilhaft ist außerdem, wenn der Einlauf durch Formgebung der Decke und des Bodens gerundet ist.Advantageous is also when the inlet is rounded by shaping the ceiling and floor is.
