Description

Die Erfindung betrifft eine Vorrichtung zur Gewinnung von Energie aus Wellen, insbesondere aus Meereswellen zur Erzeugung von elektrischen Strom und/oder zur Gewinnung von Trinkwasser, nachstehend Energiewandler zur Nutzung von Meereswellenenergie genannt. Sogenannte Wellenenergieumwandler, nachstehend Energiewandler genannt, sind bekannt. Es gibt zahlreiche Konstruktionen, aber Keine hat bisher den kommerziellen Durchbruch geschafft. Als bisher praktikabel haben sich Konstruktionen ausgezeichnet, die Wellenenergie durch Hebelkräfte in Energie umwandeln, wobei Schwimmer, die mit Auslegern verbunden sind und drehbar gelagert sind, durch die Wellen auf und ab bewegt werden. Alle bisher bekannten Systeme wandeln die Wellenenergie entweder mechanisch oder hydraulisch um, wobei alle bisher bekannten Systeme einen oder mehrere gravierende Nachteil(e) haben. Alle bisher bekannten Systeme sind mittels Konstruktionen fest mit dem Ufer oder dem Gewässergrund verbunden. Dieses setzt geeignete bauliche Maßnahmen, wie z. B. Hafenmolen voraus, oder die Engergiewandler können aufgrund der Wassertiefen nur in küstennahen Gewässern installiert werden. Als Stand der Technik mit den nicht praktikablen Ausführungen werden folgende Patente angeführt:
US 6,476,511 ; US 4,453,894 ; US 4,013,382 ; WO 2006/108421 A1 The invention relates to a device for recovering energy from waves, in particular from sea waves for generating electricity and / or for the production of drinking water, hereinafter called energy converter for the use of sea wave energy. So-called wave energy converters, hereafter called energy converters, are known. There are numerous designs, but None has made the commercial breakthrough so far. As hitherto practicable constructions have been awarded that convert wave energy by leverage into energy, with floats, which are connected to jibs and are rotatably mounted, are moved by the waves up and down. All previously known systems convert the wave energy either mechanically or hydraulically, all known systems have one or more serious drawback (s). All previously known systems are connected by means of constructions fixed to the shore or the riverbed. This sets appropriate structural measures, such. As harbor moles ahead, or the Engergiewandler can be installed due to the depths of water only in coastal waters. As prior art with the impracticable versions, the following patents are cited:
US 6,476,511 ; US 4,453,894 ; US 4,013,382 ; WO 2006/108421 A1

Eine Vorrichtung wurde vom Fraunhofer Institut CMI vorgestellt, bei der ein Schiff mit Wellenenergie-Schwimmern auf See die Energie speichern soll und dann in den Hafen zurückkehrt, um die gespeicherte Energie an Land abzugeben. Das ist unpraktikabel, weil die An- und Abfahrt des Schiffes Energie verbraucht, was das System absurd macht und es wird zusätzlich eine Schiffsbesatzung benötigt, die wiederum teuer ist.A device was presented by the Fraunhofer Institute CMI, where a ship with wave energy floats at sea should store the energy and then return to the port to deliver the stored energy ashore. This is impractical because the arrival and departure of the ship consumes energy, which makes the system absurd and it also requires a ship's crew, which in turn is expensive.

Um die fast unbegrenzt vorhandene Recource der Wellenenergie nutzbar zu machen, ist es wichtig, sowohl eine kostengünstige und effiziente Konstruktion zu schaffen, als auch eine sturmsichere Konstruktion zu schaffen, die selbst extreme Wetterverhältnisse unbeschadet übersteht.In order to harness the almost unlimited available source of wave energy, it is important to create both a cost effective and efficient design, and to create a storm proof construction that withstands even extreme weather conditions unscathed.

Der Erfindung liegt die Aufgabe zu grunde, mittels finanziell vertretbaren Aufwand eine praktikable und sichere Lösung für das Problem zu finden.The invention is based on the object to find a viable and secure solution to the problem by means of financially reasonable effort.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung mit der in Anspruch 1) angegebenen Vorrichtung.The solution of this object is achieved according to the invention with the device specified in claim 1).

Die Erfindung besteht aus einem zentralen Schwimmkörper jeglicher Form und Abmessung, vorzugsweise länglicher und/oder rechteckiger Form, z. B. ein Ponton oder Schiff, welcher als Systemträger dient und und permanent auf der ausgewählten Position verankert ist, wobei sich die Längsachse des Schwimmkörpers relativ quer zu den Wellen ausrichtet und alle zur Energieerzeugung oder Trinkwassergewinnung notwendigen technischen Einrichtungen und die Verankerungseinrichtungen aufnimmt, um den Schwimmkörper auf Position zu halten und an dessen Seiten sich Ausleger mit Schwimmern befinden, welche durch (Meeres-)Wellen auf und ab bewegt werden, wobei diese Bewegungen mittels Hydraulikzylindern oder andere geeignete Hydraulikpumpen ein Hydraulikfluid zu hydraulischen Motoren unter Niederdruck oder Hochdruck fördert, nachstehend Kraft-Übersetzer-Einheit genannt (KÜE), wobei die Energiewandler, bestehend aus Hydraulikmotoren, wiederum Generatoren zur Stromerzeugung antreiben oder Hochdruckpumpen antreiben, um mittels Umkehrosmose Trinkwasser zu erzeugen und der elektrische Strom mittels Kabeln und das Wasser mittels Schläuchen an Land befördert werden. Da sich die Kraft-Übersetzer-Einheiten (KÜE) und die Energiewandler auf einem Schwimmkörper befinden, können diese an jeder geeigneten Stelle der Welt, wo entsprechend häufig Wellengang auftritt, mittels einfachem Ankergeschirr verankert werden, wobei keine großen baulichen Maßnahmen erforderlich sind und somit eine kostengünstige und schnelle Installation möglich ist.The invention consists of a central float of any shape and size, preferably elongated and / or rectangular shape, for. As a pontoon or ship, which serves as a system carrier and is permanently anchored to the selected position, with the longitudinal axis of the floating body aligns relatively transverse to the waves and all necessary for energy production or drinking water technical equipment and the anchoring devices receives the float to hold in position and on the sides of which are outriggers with floats which are moved up and down by (marine) waves, these movements by means of hydraulic cylinders or other suitable hydraulic pumps promoting hydraulic fluid to hydraulic motors under low pressure or high pressure, hereinafter Translator unit (KUE), where the energy converters, consisting of hydraulic motors, in turn drive generators to generate electricity or drive high-pressure pumps to generate drinking water by means of reverse osmosis and the electric power by means of cables and the water by means of hoses a n country. Since the force translator units (KÜE) and the energy converters are on a float, they can be anchored at any suitable point in the world, where correspondingly frequent waves, using simple anchor harness, with no major structural measures are required and thus a inexpensive and fast installation is possible.

Zu Wartungszwecken können die Schwimmkörper mit den KÜE und dem Energiewandler in einen nahen Hafen geschleppt werden. Desweiteren können die Ausleger mit den Schwimmern zum Abschleppen, zur Wartung oder bei Sturmgefahr hochgeklappt werden, um Schäden am System zu vermeiden. Um ein hohes Maß an Stabilität des Schwimmkörpers zu gewährleisten, können zusätzliche Schwimmkörper, Gewichte oder Ballast jeglicher Art am Schwimmkörper angebracht werden.For maintenance purposes, the floats can be towed with the KÜE and the energy converter to a nearby port. Furthermore, the booms with the floats can be folded up for towing, for maintenance or in case of a storm, in order to avoid damage to the system. To ensure a high degree of stability of the float, additional floats, weights or ballast of any kind can be attached to the float.
