Abstract

The arrangement has a generator (13) for converting potential energy into electrical energy, and a floating body (1) lying below a water surface and attachable at seabed. A generator buoy (2) is formed for floating on the water surface, and connected with the floating body by a rollable hauling rope (4) or a linearly guided pinion. The generator buoy is upwardly and downwardly movable with respect to the floating body in a vertically linear manner in wave course. The floating body and the generator buoy are guided parallel to each other.

Description

Die Patentanmeldung DE 10 2010 020 219 beschreibt einen neuartigen Wellenenergiekonverter der in besonderer Weise die potentielle Wellenenergie in eine Drehbewegung einer Generatorwelle mit hoher Drehzahl umwandeln kann.The patent application DE 10 2010 020 219 describes a novel wave energy converter which can convert the potential wave energy into a rotational movement of a generator shaft at high speed in a special way.

Das System kann jedoch die Wellendrift nicht nutzen. Um die ordnungsgemäße Generatorfunktion auch bei Ebbe und Flut zu gewährleisten, müsste seine Linearführung sehr groß dimensioniert werden oder es müsste ein aufwändiger Verstellmechanismus für das Höhenniveau des unter Wasser liegenden Schwimmkörpers eingebaut werden.However, the system can not use the shaft drift. To ensure the proper generator function even at low tide and high tide, his linear guide would have to be very large dimensions or it would have a complex adjustment mechanism for the height level of the submerged floating body to be installed.

Die vorliegende Erfindung beseitigt die geschilderten Schwierigkeiten.The present invention overcomes the problems described.

Ein Wellenenergiekonverter dessen Grundaufbau dem der Anmeldung DE 10 2010 020 219 entspricht, ist dadurch gekennzeichnet, dass anstelle eines Schwimmkörpers (1) mindestens 3 Schwimmkörper (20) nach 1 bis 3 an den Auslegern (19) einer Aufnahme (24) befestigt sind und die Generatorboje (2) sich dann von dieser Aufnahme mit der Wellenbewegung abdrücken kann und dabei das Zugseil (4) abgewickelt wird, um den Generator anzutreiben.A wave energy converter whose basic structure that of the application DE 10 2010 020 219 corresponds, is characterized in that instead of a float ( 1 ) at least 3 floats ( 20 ) to 1 to 3 to the interpreters ( 19 ) of a recording ( 24 ) and the generator buoy ( 2 ) can then press off from this recording with the wave motion and thereby the pull rope ( 4 ) to drive the generator.

Die Schwimmkörper (20) können sich bei erfindungsgemäß fehlender oder längenvariabler Abspannung (16) zum Meeresgrund mit Ebbe und Flut bewegen.The floats ( 20 ) can be in accordance with the invention missing or variable-length bracing ( 16 ) to the seabed with ebb and flow.

Dabei können die Schwimmkörper (20) so ausgebildet sein, dass sie einen geringen Strömungswiderstand besitzen um die Wellenenergie für die Generatorboje (2) nicht zu absorbieren.The floats ( 20 ) be formed so that they have a low flow resistance to the wave energy for the generator buoy ( 2 ) not to absorb.

Um vergleichbar mit einem großen Schiff, die Wellenempfindlichkeit zu senken und einen schwimmenden Fixpunkt gegenüber der Generatorboje (2) zu bilden, können die Schwimmkörper (20) so ausgebildet sein, dass ihre tiefer im Wasser liegenden Bereiche mit inneren oder äußeren Gewichten beschwert sind. Die Massenträgheit des Systems: Aufnahme (24), Ausleger (19) und Schwimmkörper (20) wird damit vergrößert.To compare with a large ship, the wave sensitivity to lower and a floating fixed point against the generator buoy ( 2 ), the floats ( 20 ) be designed so that their deeper lying in the water areas with internal or external weights are weighted. The inertia of the system: recording ( 24 ), Jib ( 19 ) and floats ( 20 ) is enlarged.

Eine Ausnutzungssteigerung der Wellenenergie erhält man dadurch, dass die Schwimmkörper (20) so ausgebildet sind, dass sie die Wellen der Generatorboje (2) derart zuleiten, dass die kinetische Energie der Wellendrift in potentielle Energie einer erhöhten Wellenamplitude umgewandelt wird. Dieser Effekt kann mit horizontalen, an der Aufnahme (24) befestigten und unter Wasser liegenden Leitblechen verstärkt werden.An increase in utilization of the wave energy is obtained by the floats ( 20 ) are designed so that they the waves of the generator buoy ( 2 ) in such a way that the kinetic energy of the wave drift is converted into potential energy of an increased wave amplitude. This effect can be combined with horizontal, on the recording ( 24 ) and underwater baffles are reinforced.

Eine weitere erfindungsgemäße Ausbildung (4) erhält der Wellenenergiekonverter nach Anmeldung DE 10 2010 020 219 , wenn seine Abspannseile (16) des Schwimmkörpers (1) nicht direkt an diesem befestigt sind, sondern am unteren Ende eines am Schwimmkörper (1) befestigten Abspannungsstabes (21). Alternativ kann von dort aus nur ein Seil (16) zum Meeresgrund gespannt werden. Dieses Seil kann an einem Ende längenvariabel ausgebildet sein.Another embodiment of the invention ( 4 ) receives the wave energy converter after registration DE 10 2010 020 219 when his guy ropes ( 16 ) of the float ( 1 ) are not attached directly to this, but at the bottom of a float ( 1 ) attached tension rod ( 21 ). Alternatively, from there only one rope ( 16 ) are stretched to the seabed. This rope can be made variable in length at one end.
