Abstract

The turbine has a scissors system mounted between a rotor shaft (3) i.e. axle, and a rotor blade (2) and pulling and pushing the rotor blade from and to the rotor shaft. A horizontal movement of the rotor blade is triggered by a vertical motion of a receiving disk (1) that is vertically moved over a lifting-and lowering mechanism. The rotor blade is pulled out at the rotor shaft by the scissors system, and a centrifugal force system (6) is fastened to the receiving disk, where the rotor blade is centrally pulled by a tensioning spring (4).

Description

Problematikproblem

Eine Darrieus Windturbine mit H-Rotoren ist ein Gerät zur Energiegewinnung durch Wind. Sie haben in der Regel zwei bis fünf fest installierte Flugel Der Nachteil dieser H-Rotor-Turbine ist, das bei Sturm eine Bremsung zwar ein Weiterdrehen der Turbine verhindert, aber die Windlast nicht von den Flügeln des Rotors genommen wird Des weiteren ist die für die Bremsung notwendige Technik aufwandig, teuer und schwer Außerdem verringert man bei Sturm nicht die Windangriffsflache, wodurch heutige H-Rotor-Turbinen robuster gebaut werden mussenA Darrieus wind turbine with H-rotors is a device for generating energy through wind. They have usually two to five fixed Flugelel The disadvantage of this H-Rotor-Turbine is, that during a braking braking prevents further turning of the turbine, but the wind load is not taken from the wings of the rotor Braking necessary technology costly, expensive and heavy In addition, one does not reduce the wind attack surface during storm, whereby today's H-Rotor turbines must be built more robustly

Abhilferemedy

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Turbine zu schaffen, die die Flügel nach innen (zur Rotorwelle) zieht, bis sie nahezu anliegen. So ist eine Reduzierung der Rotorleistung moglich Außerdem verringert sich die Windlast der Windenergiegewinnungsanlage Bauteile zur Bremsung konnen wesentlich kleiner ausfallen, oder sogar (je nach Große der Windkraftanlage) vernachlassigt werdenThe specified in claim 1 invention is based on the problem of providing a turbine that pulls the wings inwards (to the rotor shaft) until they almost touch. Thus, a reduction of the rotor power is possible In addition, reduces the wind load of the wind energy extraction system components for braking can be much smaller, or even neglected (depending on the size of the wind turbine)

Realisierung einer Bewegung der Rotorblätter zur Rotorwelle Hier wird über ein Scherensystem der Flugel (2) an die Rotorwelle (3) befestigt. Eine vertikale Bewegung der Aufnahmescheibe (1) wird durch Umlenkung im Scherensystem zu einer horizontalen Bewegung Diese vertikale Bewegung der unteren Aufnahmescheibe (1) hat eine horizontale Bewegung der Flugel zur Folge Um einen Langenunterschied durch die Bewegung auszugleichen, ist ein Schienensystem (4) an der oberen Scherenbefestigung des Flugelblattes notwendig Ein weiteres Schienensystem ist auf der Welle befestigt Auf diesem Schienensystem (7) lauft die Aufnahmescheibe, um ein Verdrehen zu verhindernRealization of a movement of the rotor blades to the rotor shaft Here is via a scissor system of the wing ( 2 ) to the rotor shaft ( 3 ) attached. A vertical movement of the receiving disc ( 1 ) is deflected in the scissors system to a horizontal movement This vertical movement of the lower pick-up disc ( 1 ) results in a horizontal movement of the wings To compensate for a long difference by the movement, a rail system ( 4 ) on the upper scissors attachment of the Flugelblatt necessary Another rail system is attached to the shaft on this rail system ( 7 ) runs the pickup disk to prevent twisting

Die Windanlage ist im eingefahrenen Zustand sehr kompakt und gut zu transportieren Ideal für mobile AnwendungenAt the receiving disc ( 1 ) is a centrifugal system ( 6 This centrifugal system releases an attachment point at an adjustable maximum speed. After this point has been released, the take-up disc ( 1 ) Pulled down part of the pulling force is deflected by the scissor joint and the rotor blades are pulled to the center The necessary train is by a tension spring ( 8th Ensured in the shaft The system described above is a small system It is quickly assembled and disassembled by the scissors system. The wind turbine is very compact and easy to transport when retracted Ideal for mobile applications

Zu Patentanspruch 3To claim 3

Um große Anlagen mit diesem Scherensystem auszurüsten ist ein Verstellen der Aufnahmescheibe (1) und das daraus resultierende Heranziehen der Rotorflugel nur mit Motorkraft zu realisieren Der Motor (9) befindet sich hierbei im Unteren Teil der rotierenden Welle und zieht den Aufnahmeteller durch eine Gewindeachse nach unten Hierbei wird die Gewindeachse über ein Gegenstuck (ahnlich einer Mutter für Schloßschrauben) mit der Aufnahmescheibe verbunden Wird die Achse nun in Drehung versetzt, gleitet die Aufnahmescheibe (1) je nach Drehrichtung auf oder ab Der Vorteil einer motorbetriebenen Verstellung istTo equip large systems with this scissors system is an adjustment of the receiving disc ( 1 ) and to realize the resulting attraction of the rotor blade only with engine power. 9 ) is in this case in the lower part of the rotating shaft and pulls the receiving plate through a threaded axis down Here, the threaded axis is connected via a Gegenstuck (similar to a nut for Schloßschrauben) with the receiving disc If the axis is now rotated, slides the receiving disc ( 1 ) depending on the direction of rotation up or down The advantage of a motorized adjustment is

Die Steuerbarkeit der Rotorleistung Hier wird ein Heranziehen und Herausfahren der Rotorflugel moglich Z B ist die Windanlagenleistung bei starken Wind zu reduzieren (Flügel auf einen bestimmten Abstand zur Welle hin einzufahren) und muss nicht ganz abgestellt werden Außer dem ist bei Wartungsarbeiten so die Drehkraft von der Welle zu nehmen.The controllability of the rotor power Here, a pulling in and out of the rotor wing is possible ZB is the wind turbine performance in strong wind to reduce (wing at a certain distance to the shaft to retract) and does not have to be completely turned off Besides that, during maintenance, so the rotational force from the shaft to take.
