Description

Eine kombinierte Wellen-und Windanlage ist in der DE 4423454 A1 beschrieben, bei der sich die hohe Windkraftanlage im Rhythmus der Meereswellen mitbewegt.A combined wave and wind turbine is in the DE 4423454 A1 described, in which the high wind turbine moves with the rhythm of the sea waves.

In der DE 3633145 A1 ist ein Wellenkraftwerk beschrieben bei dem in einem Trägerrost elektrische Spulen montiert sind. In den Spulen bewegen sich Anker im Rhythmus der Wellenbewegung und erzeugen durch die Relativbewegung elektrische Energie.In the DE 3633145 A1 describes a wave power plant in which electrical coils are mounted in a carrier grate. Anchors move in the coils in the rhythm of the wave movement and generate electrical energy through the relative movement.

In der DE 3220381 A1 wird die Umwandlung der linearen Schwimmerbewegung in eine Drehbewegung beschriebenIn the DE 3220381 A1 the conversion of the linear float movement into a rotary movement is described

In der DE 197 14 512 C2 wird eine maritime Kraftwerksanlage beschrieben um Energie aus Meereswärme, Meereswellen, Windkraft und Solarstrahlung zu gewinnen. Die schwimmende Kraftwerksinsel gemäss allen 5 Zeichnungen soll durch ein schnell aufholbares und wieder verwendbares Verankerungssytem am Meeresgrund befestigt werden.In the DE 197 14 512 C2 describes a maritime power plant to generate energy from sea heat, sea waves, wind power and solar radiation. The floating power station island according to all 5 drawings is to be attached to the sea floor by a fast-catching and reusable anchoring system.

Für einen Bojenbetrieb in erster Linie, aber auch für den Windbetrieb ist jedoch eine zuverlässige Verankerung unerlässlich.For buoy operation in the first place, but also for wind operation a reliable anchor essential.

Ich habe mir die Aufgabe gestellt, zu den in der Literatur beschriebenen Windkraftwerken Wellenkraftwerke dazuzubauen.I have set myself the task to the wind power plants described in the literature to assemble.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöstThis task is due to the characteristics of claim 1 solved

Ein Ausführungsbeispiel des Gegenstandes der Erfindung ist vereinfacht in der ZeichnungAn embodiment of the subject of Invention is simplified in the drawing

1 dargestellt und im folgenden näher beschrieben: 1 shown and described in more detail below:

1 zeigt einen Rohrturm 1 vorzugsweise aus Beton oder Stahl gefertigt und trägt einen mehrteiligen Schwimmer 2. Am Schwimmer 2 sind mehrere Kraftübertragungsstangen 3 befestigt, die im Rohrturm 1 an einer Schweisskonstruktion 4 montiert sind. Die Länge der Kraftübertragungsstangen 3 ergibt sich aus der Summe von Gezeitenhöhe + Wellenhöhe + einem Sicherheitsabstand. Die Schweisskonstruktion 4 führt die Kraftübertragungsstangen 3 und trägt die Kolbenstange 5 für den Arbeitszylinder 7 1 shows a pipe tower 1 preferably made of concrete or steel and carries a multi-part float 2 , On the swimmer 2 are several power transmission rods 3 attached to the pipe tower 1 on a welded construction 4 are mounted. The length of the power transmission rods 3 results from the sum of tidal height + wave height + a safety distance. The welded construction 4 guides the power transmission rods 3 and carries the piston rod 5 for the working cylinder 7

Bei einer Bewegung der Kolbenstange 5 fördert der Kolben 6 die Hydraulikflüssigkeit in den Druckspeicher. Die Flüssigkeit treibt von dort einen Axialkolbenmotor an und fliesst über den Rücklaufspeicher in den Arbeitszylinder 7 zurück. Der Axialkolbenmotor treibt den Generator an.When the piston rod moves 5 promotes the piston 6 the hydraulic fluid in the pressure accumulator. From there, the liquid drives an axial piston motor and flows into the working cylinder via the return accumulator 7 back. The axial piston motor drives the generator.

Alle mechanischen Teile, wie Arbeitszylinder 7, Axialkolbenmotor, Druckspeicher etc . sind im Rohrturm 1 auf einem stählernen Aufnahmerahmen montiert. Ein Hebezeug kann dann die Rahmen samt der Mechanik nach Demontage des Windaggregates herausheben.All mechanical parts, such as working cylinders 7 , Axial piston motor, pressure accumulator etc. are in the tube tower 1 mounted on a steel mounting frame. A hoist can then lift out the frame including the mechanics after dismantling the wind unit.

Alle o.g. Teile sind im Rohrturm 1 frei zugänglich.All of the above parts are in the tubular tower 1 freely accessible.

Der Schwimmer 2 wird am Rohrturm 1 durch eine Kugelumlaufführung geführt. Die Kugeln sind aus Elastomeren und sitzen in Schalen. Diese Schalen sind miteinander elastisch verbunden, was verhindert, dass sich die Kugeln trotz Verformung gegenseitig behindern. Die Führung des Schwimmers 2 kann auch durch Laufrollen und Führungsschienen erfolgen.The swimmer 2 is at the tube tower 1 guided by a recirculating ball guide. The balls are made of elastomers and sit in bowls. These shells are elastically connected to one another, which prevents the balls from interfering with one another despite deformation. The guidance of the swimmer 2 can also be done by rollers and guide rails.

Bei der vorgeschlagenen Konstruktion sind die Aussenteile: Schwimmer 2 ausserhalb und Kraftübertragungsstangen 3 teilweise ausserhalb des Rohrturmes 1 installiert und von den empfindlicheren Innenteilen: Axialkolbenmotor, hydraulische Aggregate, getrennt.The outer parts of the proposed construction are: floats 2 outside and power transmission rods 3 partly outside the tube tower 1 installed and separated from the more sensitive inner parts: axial piston motor, hydraulic units.

Die Kraftübertragungsstangen 3 sind sowohl ausserhalb als auch innerhalb des Rohrturmes 1 angeordnet.The power transmission rods 3 are both outside and inside the tube tower 1 arranged.

Die Durchführung der Kraftübertragungsstangen 3 von der Rohrturmaussenseite nach Innen liegt oberhalb des höchsten Wasserspiegels, daher entfallen Dichtungsprobleme.Implementation of the power transmission rods 3 from the outside of the pipe tower lies above the highest water level, so there are no sealing problems.

Wenn der Wind nachlässt, gibt es noch Wellen, die ausgenutzt werden können.When the wind subsides, there is there are still waves that can be exploited.

Bei einer Windgeschwindigkeit von 20 – 25 m/s wird eine Windkraftanlage aus Sicherheitsgründen ausser Betrieb genommen, eine Wellenkraftanlage noch nicht.At a wind speed of 20 - 25 m / s a wind turbine is taken out of operation for safety reasons, not yet a wave power plant.

Durch eine Wasserfüllung kann das Gewicht des Schwimmers 2 variiert werden.By filling the water, the weight of the swimmer can 2 can be varied.

Bei irgendwelchen Undichtigkeiten im Hydrauliksystem kann kein Öl ins Meer gelangen. Die Umweltbelastung der Anlage ist gleich Null.With any leaks there is no oil in the hydraulic system get into the sea. The environmental impact of the plant is zero.

Durch Verschieben des Arbeitszylinders 7 kann der Schwimmer hochgehoben oder abgesenkt werden, um unterschiedliche Ausgangsstellungen zu ermöglichen, die den jeweiligen Gezeitenstand berücksichtigen.By moving the working cylinder 7 the float can be raised or lowered to enable different starting positions that take into account the respective tidal level.

Die Umwandlung der Wellenenergie ist hier beispielsweise nur über mechanische Aggregate beschrieben. Sie kann aber auch durch andere Systeme oder elektromechanische Wandler erfolgen,.The conversion of wave energy is just over here, for example mechanical units described. But it can also be done by others Systems or electromechanical transducers are made.
