Abstract
Description
Die Erfindung betrifft eine Windenergieanlage mit einem Turm, einem auf dem Turm um dessen Achse drehbar gelagerten Kopf und einem von dem Kopf getragenen, aus wenigstens einem Rotorblatt, einer Rotornabe, ggf. Getriebe und einem Generator bestehenden Antriebsstrang ist.The The invention relates to a wind turbine with a tower, a on the tower about its axis rotatably mounted head and one of worn from the head, from at least one rotor blade, a rotor hub, if necessary gearbox and a generator existing powertrain is.
Bei Windenergieanlagen besteht das Problem, das zum Absenken eines auszutauschenden oder am Boden zu reparierenden Antriebsstrangs und zum Aufziehen des Antriebsstrangs als Ganzes oder auch nur eines seiner Elemente ein Kran herbeigeschafft werden muss, dessen Arbeitshöhe der des Antriebsstrangs entspricht.at Wind turbines have the problem of lowering or exchanging a to be repaired on the ground drivetrain and for mounting the Drivetrain as a whole or just one of its elements Crane must be procured, the working height of the drive train equivalent.
Der Einsatz eines solchen Krans ist mit erheblichen Kosten verbunden.Of the Use of such a crane is associated with considerable costs.
Der Erfindung liegt die Aufgabe zugrunde, eine Windenergieanlage der eingangs genannten Art zu schaffen, bei der ein Absenken und Aufziehen des Antriebsstrangs (einschließlich des Rotors) ohne einen gesondert herbeizuschaffenden Kran möglich wird.Of the Invention is based on the object, a wind turbine of the to create the aforementioned type, in which a lowering and mounting of the powertrain (including the rotor) is possible without a crane to be made separately.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Kopf mit Kranseilführungsmitteln versehen als ein ein Absenken und Aufziehen des Antriebsstrangs erlaubender Krankopf ausgebildet ist.According to the invention this Task solved by that the head with crane cable guides provided as a lowering and tightening of the drive train permitting crane head is formed.
Ein bevorzugtes Ausführungsbeispiel zeichnet sich dadurch aus, dass das Getriebe in der Rotornabe angeordnet ist, wobei das Getriebe bevorzugt ein Planetengetriebe ist, dessen Hohlrad in das Gehäuse der Rotornabe eingepasst ist. Dieses Ausführungsbeispiel erlaubt eine besonders kurze Ausbildung des Antriebsstrangs und damit ein relativ kurzes Herausragen des Antriebsstrangs über den Turm hinaus, wodurch die Belastung des Krankopfes reduziert wird, diese Ausbildung ist auch ohne Verwirklichung der Merkmale des Anspruchs 1 denkbar.One preferred embodiment is characterized by the fact that the transmission is arranged in the rotor hub is, wherein the transmission is preferably a planetary gear, whose Ring gear in the housing the rotor hub is fitted. This embodiment allows a especially short training of the powertrain and thus a relative briefly protrude the drive train beyond the tower, which the load on the crane head is reduced, this training is even without realizing the features of claim 1 conceivable.
Eine bevorzugte Ausgestaltung zeichnet sich durch einen von an der Außenfläche des Turms angebrachten Schienen Fahrkorb aus. Dieses Ausführungsbeispiel erlaubt das Aufziehen eines Kranseils (oder eines Vorseils) außerhalb des Turms, der in dem Fahrkorb auffahrende Monteur legt dieses dann um die Kranführungselemente.A preferred embodiment is characterized by a on the outer surface of the Tower mounted rail car. This embodiment allows the hoisting of a crane rope (or a pre-rope) outside of the tower, the mechanic ascending in the car then transfers this the crane guide elements.
Ein weiteres Ausführungsbeispiel zeichnet sich aus durch Mittel zum Neigen des Antriebsstrangs relativ zu der Horizontalen. Diese Ausbildung erlaubt es, eine Neigung des Antriebsstrangs nur dann einzustellen, wenn die jeweilige Windstärke dies (zur Sicherstellung eines Nichtkollidierens der sich im Wind durchbiegenden Rotorblätter mit dem Turm) erfordert, so dass das bei Neigung des Antriebsstrangs durch das Gewicht der Rotorblätter auf dessen Lager ausgeübte Drehmoment zeitlich minimiert werden kann. Auch dieses Ausführungsbeispiel ist ohne Verwirklichung der Merkmale des Anspruchs 1 möglich.One another embodiment is characterized by means for tilting the drive train relative to the horizontal. This training allows a tendency of the Adjust powertrain only if the respective wind force is (to ensure a non-collision of the wind deflecting rotor blades with the tower), so that when inclining the drive train by the weight of the rotor blades exercised on its stock Torque can be minimized in time. This embodiment is also without realizing the features of claim 1 possible.
Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur eine schematische Schnittansicht durch den oberen Teil einer erfindungsgemäß ausgebildeten Windenergieanlage.The Invention will be explained below with reference to a drawing. there the single figure shows a schematic sectional view through the upper part of an inventively designed Wind turbine.
