Abstract

The invention relates to a novel form of wave energy conversion in which a suitable installation that is located in the immediate influx region of the waves, i.e. in the immediate vicinity of the water/shore, absorbs the force of the waves in continuous motion and converts said force into another force. Said force can then be used for all force conversion units. The aim of the invention is to develop a device which can optimise the use of the energy contained in the waves in the shore region or rivers. According to the invention, one or more wave impeller wheels are mounted horizontally in a frame in a height-adjustable steel construction that is situated in the water, the discontinuous rotation of said wheels being converted by gears into a continuous rotation. The distance between the wave impeller wheels is dimensioned according to the average frequency of the wave.

Kurze Beschreibung der AbbildungenBrief description of the illustrations
[0011] Die Erfindung wird anhand von Abbildungen näher erläutert. Dazu zeigt Figur 1 die erfindungsgemäße Wasserwellenenergiegewinnungsanlage und in Figur 2 wird die Wirkungsweise skizziert.The invention will be explained in more detail with reference to figures. 1 shows the water wave energy recovery system according to the invention and in Figure 2, the operation is outlined.
Ausführung der ErfindungEmbodiment of the invention
[0012] Die in Figur 1 gezeigte Vorrichtung besteht aus einer Stahlkonstruktion, welche auf einbetonierten Stützen 1 im Wasser steht. Die Vorrichtung kann beispielsweise vor einer Küste in der Uferzone eingesetzt werden und nutzt die Energie der Wasserwellen. Auf den Stützen 1 ist ein Rahmen 2 angeordnet, welcher die Wellenflügelräder 3 aufnimmt und in der Höhe verstellbar ist. Die Wellenflügelräder 3, die aus einem Leichtmaterial, z.B. glasfaser- oder kohlefaserverstärkten Kunststoff, gefertigt sind, sind auf einer horizontalen Achse innerhalb des Rahmens 2 gelagert. Die Anzahl der Flügel 4 der Wellenflügelräder 3 richtet sich hauptsächlich nach der Amplitude der Wasserwelle. Für eine ausreichende Stabilität werden mindestens drei Flügel 4 vorgesehen. Die Konstruktion funktioniert allerdings auch mit lediglich einem Flügel 4. In dem Rahmen 2 können ein oder mehrere Wellenflügelräder 3 angeordnet werden. Der Abstand der Wellenflügelräder 3 voneinander ist von der durchschnittlichen Frequenz der Wasserwelle abhängig. So haben in der Ostsee die Wasserwellen eine andere Amplitude und Frequenz als beispielsweise in der Nordsee oder im Atlantik. Neben den grundsätzlich anderen Frequenzen und Amplituden können diese auch aufgrund von unterschiedlichen Windverhältnissen variieren. Entsprechend muss die Vorrichtung dimensioniert werden und es muss die Möglichkeit geschaffen werden, Schwankungen auszugleichen. So können für eine optimale Kraftumsetzung die Wellenflügelräder 3 einzeln in der Höhe und in ihrem Abstand zueinander verstellbar sein.The apparatus shown in Figure 1 consists of a steel structure, which stands on cast-in supports 1 in the water. The device can be used for example in front of a coast in the riparian zone and uses the energy of the water waves. On the supports 1, a frame 2 is arranged, which receives the wave impellers 3 and is adjustable in height. The Wellenflügelräder 3, which are made of a light material, such as glass fiber or carbon fiber reinforced plastic, are mounted on a horizontal axis within the frame 2. The number of wings 4 of the wave impellers 3 depends mainly on the amplitude of the water wave. For sufficient stability at least three wings 4 are provided. However, the construction also works with only one wing 4. In the frame 2, one or more wave impellers 3 can be arranged. The distance of the wave impellers 3 from each other is dependent on the average frequency of the water wave. Thus, in the Baltic Sea, the water waves have a different amplitude and frequency than, for example, in the North Sea or in the Atlantic. In addition to the fundamentally different frequencies and amplitudes, these can also vary due to different wind conditions. Accordingly, the device must be dimensioned and the possibility must be created to compensate for fluctuations. Thus, for optimum force conversion, the wave-flywheels 3 can be individually adjustable in height and in their distance from one another.
[0013] Die Stahlkonstruktion wird je nach Amplitude der Wellen in der Höhe ausgerichtet. Dies wird in der Regel hydraulisch erfolgen. Es können aber durchaus auch andere Verstellmechanismen angewendet werden. Ebenso werden die Wellenflügelräder 3 auf dem Rahmen 2 horizontal verstellbar angeordnet.The steel structure is aligned depending on the amplitude of the waves in height. This will usually be done hydraulically. But it can also be used quite other adjustment mechanisms. Likewise, the wave-wing wheels 3 are arranged horizontally adjustable on the frame 2.
[0014] Wie in Figur 2 dargestellt, wird ein Wellenflügelrad 3 von je einer Welle angetrieben. Die dabei entstehende diskontinuierliche mechanische Drehbewegung wird über Getriebe, insbesondere Kettengetriebe, in eine kontinuierliche Drehbewegung umgewandelt und treibt damit einen oder mehrere Generator zur Erzeugung von elektrischer Energie an, welcher sich ebenfalls auf der Anlage befindet. Die Wellenflügelräder 3 lassen sich an die Wellenhöhe anpassen, so dass ein ständiges maximales Drehmoment erzeugt wird. Die notwendigen Transformatoren zur Umwandlung und Weiterleitung des Stroms können an Land stationiert werden.As shown in Figure 2, a wave impeller 3 is driven by a respective shaft. The resulting discontinuous mechanical rotational movement is converted via transmission, in particular chain transmission, in a continuous rotary motion and thus drives one or more generators for generating electrical energy, which is also located on the system. The wave impellers 3 can be adapted to the wave height, so that a constant maximum torque is generated. The necessary transformers to convert and forward the electricity can be stationed ashore.
[0015] Durch die Anordnung mehrerer Wellenflügelräder 3 hintereinander im Frequenzabstand der Wellen kann die Energie der Wellen optimal ausgenutzt werden.By arranging several wave impellers 3 in a row in the frequency separation of the waves, the energy of the waves can be optimally utilized.
[0016] Eine Notabschaltung aufgrund von Sturm erfolgt, indem die gesamte Anlage aus dem Bereich der Wellen gehoben wird. Des weiteren ist es auch möglich, dass die einzelnen Flügel der Wellenflügelräder verstellbar sind und so zusätzlich durch die Stellung der Flügel die Notabschaltung realisiert wird.An emergency shutdown due to storm takes place by the entire system is lifted out of the range of waves. Furthermore, it is It is also possible that the individual wings of the wave-wiper wheels are adjustable and thus the emergency shutdown is additionally realized by the position of the wings.
[0017] Wasserwellenenergiegewinnungsanlage kann in Kombination als Kompaktanlage mit Fotovoltaikanlage, Windkraftanlage und Pumpspeicherwerk ausgeführt sein. Beispielsweise kann die ständige mechanische Drehbewegung für den Antrieb von Pumpen für ein Pumpspeicherwerk genutzt werden.Wasserwellenenergiegewinnungsanlage can be designed in combination as a compact system with photovoltaic system, wind turbine and pumped storage. For example, the constant mechanical rotary motion can be used to drive pumps for a pumped storage power plant.
[0018] Denkbar ist ebenfalls der Einsatz derIt is also conceivable the use of
Wasserwellenenergiegewinnungsanlage auch bei einer kontinuierlichen Wasserbewegung in einem Strömungskanal oder Fluss. Water wave energy recovery system even with a continuous water movement in a flow channel or river.
