Abstract
die Patentanmeldung "Windkraftanlage mit hintereinander angeordneten Rotoren auf horizontalen Wellen und drehendem Turm zur Kraftübertragung" baut auf der DE 102007016756 A1 auf. Zur Erhöhung der Effizienzsteigerung wird ein zweiter Rotor hinter dem drehenden Mast angeordnet. Die dreidimensionalen Blattgeometrien der beiden Rotoren sollen so ausgebildet sein, dass jeder in etwa die gleiche Leistung entwickelt. Ungleichheit soll durch Regelung der Blattverstellung bzw. durch den Einbau von Freilaufeinrichtungen ausgeglichen werden. Der zweite Rotor kann auf der gleichen horizontalen Welle wie der erste, aber auch auf einer zweiten Welle, die mit der ersten Welle fluchtet, angeordnet sein. Das durch die Kraftübertragung von der/den horizontalen Welle/n auf den Turm entstehende Drehmoment kann durch die Anordnung der beiden horizontalen Wellen am Turmkopf im Abstand von der vertikalen Mittellinie weitestgehend ausgeglichen werden, so dass die regulierende Windfahne entfallen kann.the patent application "wind turbine with successively arranged rotors on horizontal shafts and rotating tower for power transmission" is based on DE 102007016756 A1. To increase efficiency, a second rotor is placed behind the rotating mast. The three-dimensional blade geometries of the two rotors should be designed so that each develops approximately the same power. Inequality should be compensated by regulating the pitch adjustment or by the installation of freewheel devices. The second rotor can be arranged on the same horizontal shaft as the first, but also on a second shaft, which is aligned with the first shaft. The torque generated by the power transmission from the horizontal shaft (s) to the tower can be largely compensated for by the arrangement of the two horizontal shafts at the top of the tower at a distance from the vertical center line, so that the regulating wind vane can be dispensed with.
Description
Windkraftanlage mit hintereinander angeordneten Rotoren auf horizontalen Wellen und drehendem Turm zur Kraftübertragung.Wind turbine with successively arranged rotors on horizontal shafts and rotating tower for power transmission.
In der Vergangenheit gab es Lösungen, die Gesamtleistung eines Windkraftsystems durch die Verwendung eines zweiten oder mehren Rotoren zu erhöhen. In den 30er Jahren im 20. Jahrhundert flog ein Großflugzeug von Dornier Typ DoX mit 6 Motoren und mit je einem Rotor vor und hinter dem Motor angeordnet, also mit insgesamt 12 Rotoren.In There were solutions to the past, the overall performance of a Wind power system through the use of a second or more Increase rotors. In the 30s in the 20th century flew a large aircraft of Dornier type DoX with 6 engines and arranged with one rotor each in front of and behind the engine, ie with a total of 12 rotors.
Es gab auch bei früheren Windkraftanlagen Lösungsansätze mit zwei hintereinander angeordneten Rotoren, die gleichlaufend oder gegenläufig waren. Diese Anordnung hat sich nicht durchgesetzt, da durch Wegfall der Windfahne das „in den Wind Stellen" schwer durchführbar war bzw. durch das Vorhandensein von Getriebe/Generator auf der Plattform die Anordnung eines zweiten Rotors konstruktiv nur schwer gelöst werden konnte. Auch beeinflussen sich beide Rotoren gegenseitig.It gave solutions to previous wind turbines with two successively arranged rotors, the same running or in opposite directions. This arrangement did not work enforced, because by omission of the wind vane the "in the Wind places "was difficult to carry out or by the presence from gearbox / generator on the platform arranging a second Rotor's constructive could be solved only with difficulty. Also Both rotors influence each other.
In der Praxis beweisen hintereinander angeordnete gegenläufige Rotoren z. B. bei Hubschraubern oder bei Fans für Triebwerke, dass diese zu einer Effizienzsteigerung führen.In In practice, counter-rotating ones are arranged one behind the other Rotors z. Helicopters or fans of engines, that these lead to an increase in efficiency.
Die Erfindung wird mit Hilfe der Anmeldung 10 2007 016 756.5 „Windkraftanlage mit horizontal liegender Rotorwelle und drehendem Turm zur Kraftübertragung" ermöglicht. In dieser Anmeldung wird die Kraftübertragung von der horizontalen Welle auf den am Fuß gelagerten drehenden Turm mittels eines speziellen Winkelgetriebes geleitet, so dass die Stromerzeugung im Fuß des Turmes stattfinden kann.The Invention is using the application 10 2007 016 756.5 "wind turbine with horizontal rotor shaft and rotating tower for power transmission " allows. In this application, the power transmission from the horizontal shaft to the rotating one mounted on the foot Tower guided by a special angle gear, so that Electricity generation can take place in the foot of the tower.
Auf der Turmspitze dreht sich die Plattform mit der Lagerung der Rotorwelle, dem Winkelgetriebe und der Windfahne. Somit ist sowohl das Gewicht am Mastkopf reduziert als auch Platz für weitere Anwendungen gewonnen.On the tower top rotates the platform with the bearing of the rotor shaft, the angular gear and the wind vane. Thus, both the weight on Mast head reduced as well as space for further applications won.
Erfindungsgemäß wird hinter dem ersten Rotor vor dem Mast ein zweiter Rotor hinter dem Mast angeordnet. Die dreidimensionalen Blattgeometrien der Rotoren müssen den Strömungsprofilen des Windes entsprechend ausgebildet sein, damit jeder Rotor ca. die gleich hohe Leistung entwickeln kann.According to the invention behind the first rotor in front of the mast a second rotor behind the mast Mast arranged. The three-dimensional blade geometries of the rotors have to match the airfoils of the wind accordingly be formed so that each rotor about the same high power can develop.
