Abstract

Es wird ein schwimmendes Windrad beschrieben, bei dem das Rotorlager von zwei Stützen gehalten wird. Spannseile nehmen die durch den Winddruck entstehenden Kräfte auf. V-förmig angeordnete Röhrenschwimmkörper weisen eine hohe Kenterfestigkeit auf, haben einen geringen Materialbedarf und einen geringen Tiefgang. Für eine leichtere Montage des Rotors können die Stützen gekippt werden.A floating wind turbine is described in which the rotor bearing is held by two supports. Tension ropes absorb the forces created by the wind pressure. V-shaped tubular floats have a high capsule strength, require little material and have a shallow draft. The supports can be tilted for easier assembly of the rotor.

Description

Offshore Windparks sind zumeist mit auf dem Meeresboden gegründeten Windrädern aufgebaut. Die Gründung ist aufwändig und die Kosten steigen mit der Wassertiefe exponentiell. An vielen Küsten fällt der Meeresboden schnell auf Tiefen von mehr als 50 m. Mit schwimmenden Windrädern ist eine Windstromgewinnung unabhängig von der Wassertiefe möglich.Offshore wind farms are mostly constructed with wind turbines based on the seabed. The foundation is complex and the costs increase exponentially with the depth of the water. On many coasts the seabed quickly falls to depths of more than 50 m. With floating wind turbines, wind power generation is possible regardless of the depth of the water.

Hier wird ein Schwimmkörper beschrieben, der geringen Tiefgang, einen geringen Materialverbrauch und eine hohe Kenterfestigkeit aufweist.Here, a floating body is described, which has low draft, low material consumption and a high center strength.

Das Rotorlager (3) des Ringwindrads steht auf Stützen (4), die wiederum auf den Röhrenschwimmkörpern (1) stehen.The rotor bearing ( 3 ) of the ring wind wheel stands on supports ( 4 ), which in turn on the tube floats ( 1 ) stand.

Anstelle einer dritten Stütze kann das Windrad auch durch Spannseile (5) abgestützt werden. Die Spannseile führen vom Rotorlager zu den Enden der Röhrenschwimmkörper. Die Spannseile nehmen dann insbesondere die durch den Winddruck entstehenden Kräfte auf. Der durch den Ring direkt angetriebene Generator (6) kann an einer der Stützen (4) befestigt werden. Die minimiert den Aufwand für die Generatorhalterung (8). Der Zugang zum Generator ist einfach zu schaffen.Instead of a third support, the wind turbine can also by tensioning cables ( 5 ) are supported. The tensioning cables lead from the rotor bearing to the ends of the tubular floating bodies. The tension cables then absorb in particular the forces resulting from the wind pressure. The generator directly driven by the ring ( 6 ) can be attached to one of the supports ( 4 ) are attached. This minimizes the effort for the generator bracket ( 8th ). Access to the generator is easy to create.

Werden die Stützen (4) kippbar ausgeführt, so können diese bei der Montage gekippt werden und der Ringrotor kann auf das Rotorlager gesetzt werden. Hierfür reichen die üblichen Krane in den Werften aus. Nach dem Aufsetzen des Rotors werden die Stützen mit dem Rotor aufgerichtet und verspannt.Are the supports ( 4 ) tilted, so they can be tilted during assembly and the ring rotor can be placed on the rotor bearing. For this, the usual cranes in the shipyards are sufficient. After placing the rotor, the supports are erected with the rotor and braced.
