Description
Die Erfindung bezieht sich auf einen Gezeitengenerator für die Erzeugung elektrischer Energie aus dem Wellenhub und aus der Meeresströmung.The invention relates to a tide generator for the generation of electrical energy from the wave stroke and from the ocean current.
Ein Meeresströmungskraftwerk ist laut Wikipedia ein Wasserkraftwerk, das aus der natürlichen Meeresströmung Elektrizität erzeugt. Es wird dabei nicht, wie bei den meisten anderen Wasserkraftanlagen, ein Stauwerk errichtet, sondern die Turbine steht an einem Mast frei in der Strömung. Zu den entscheidenden Vorteilen derartiger Meeresströmungskraftwerke zählt die Tatsache, dass Meeresströmungen kontinuierlich fließen und sich dadurch gut vorhersagen lassen, wodurch sich die Qualität eines Standortes gut einschätzen läßt. Zudem benötigen Meeresströmungskraftwerke eine nur geringe Strömungsgeschwindigkeiten, da die Dichte des Wassers wesentlich größer als die von Luft ist.An ocean current power plant is, according to Wikipedia, a hydroelectric power station that generates electricity from the natural ocean currents. It is not, as with most other hydroelectric power plants, built a dam, but the turbine is free on a mast in the flow. One of the key advantages of such ocean current power plants is the fact that ocean currents flow continuously and can therefore be easily predicted, which makes it easy to assess the quality of a site. In addition, ocean current power plants require only low flow velocities since the density of the water is much greater than that of air.
Kommerzielle Meeresströmungskraftwerke sind in der Regel komplett in das umgebende Wasser eingetaucht, da eine Durchmischung der Wasserströmung mit Luft zu einem rapiden Sinken der Dichte der Strömung und damit einem Leistungseinbruch führen würde. Zudem werden in diesem Fall Probleme, wie Korrosion aufgrund höherer Luftzufuhr, vermieden. Meeresströmungskraftwerke sind in ihrem Betrieb ähnlich umweltverträglich wie Windkraftanlagen oder Solarkraftwerke, da ihre Turbinen keine Abfallstoffe, wie zum Beispiel Kohlenstoffdioxid, emittieren. Auch sind infolge der langsamen Rotation des Rotors Meeresströmungskraftwerke für Fische und andere Meerestiere praktisch ungefährlich.Commercial ocean current power plants are usually completely submerged in the surrounding water, since mixing the water flow with air would cause a rapid decrease in the density of the flow and thus a power dip. In addition, problems such as corrosion due to higher air supply are avoided in this case. Oceanic power plants are as environmentally sound in their operation as wind turbines or solar power plants because their turbines do not emit any waste materials, such as carbon dioxide. Also, due to the slow rotation of the rotor sea current power plants for fish and other marine animals are virtually safe.
Zu den Nachteilen von Meeresströmungskraftwerken gehört ihre mangelnde Wirtschaftlichkeit; außerdem ist in der Nähe derartiger Anlagen nur dann ein effektiver Fischfang möglich, wenn der Wasserspiegel über der Turbine ausreichend hoch ist. Ferner sind bei der Errichtung der Turbinen Wechselwirkungen mit möglichen Schiffsbewegungen zu berücksichtigen. Auch stellt die Installation der Anlagen eine wasserbau- und stahlbautechnische Herausforderung dar, weil Bauarbeiten auf offener See oder in Flüssen anspruchsvoll sind und die Baumaterialien unterwassertauglich und gegen Salzangriff gerüstet sein müssen. Ihre Wartung ist häufig aufwendig, da sich die Anlagen unter Wasser befinden und dadurch schwer erreichbar sind.The disadvantages of ocean current power plants include their lack of efficiency; In addition, effective fishing is only possible near such facilities if the water level above the turbine is sufficiently high. Furthermore, when constructing the turbines, interactions with possible ship movements have to be considered. Also, the installation of the facilities represents a hydraulic engineering and steel engineering challenge, because construction work on the open sea or in rivers are demanding and the building materials must be suitable for underwater and against salt attack. Their maintenance is often expensive, since the plants are under water and therefore difficult to reach.
Demgegenüber schwimmt ein Wellengenerator gleichsam im Meer bzw. er wird lediglich auf dem Meeresboden verankert, wie dies beispielsweise auf der Website „https://www.slimlife.eu/wellengenerator.html“ beschrieben ist. Die schwimmende Anlage wird dabei einfach zu ihrem vorgesehenen Standort geschleppt und dort verankert. Allerdings sind die Energieausbeuten eines reinen Wellengenerators vergleichweise gering.In contrast, a wave generator floats as it were in the sea or it is anchored only on the seabed, as described for example on the website "https://www.slimlife.eu/wellengenerator.html". The floating system is simply towed to its intended location and anchored there. However, the energy yields of a pure wave generator are comparatively low.
Die Druckschrift
Aufgabe der Erfindung ist es, eine Anordnung der eingangs genannten Art bereitzustellen, die eine optimale Nutzung der Meeresenergie ermöglicht.The object of the invention is to provide an arrangement of the type mentioned, which allows optimal use of ocean energy.
Die Erfindung löst diese Aufgabe durch eine Kombination wenigstens eines Wellengenerators und wenigstens eines Strömungsgenerators, die zusammen mit einer Seezeicheneinheit, einer Zentraleinheit, einer Auftriebs- und Richtungseinheit, wenigstens einer Strömungsturbine mit einem vertikalen Rotor sowie einer mechanischen Blattverstellung in angenähert vertikaler Richtung bewegbar auf einer Starrachse angeordnet sind, die an einem auf dem Meeresboden ruhenden und dort gegebenenfalls verankerbaren Grundgewicht unterhalb der Wasseroberfläche schwenkbar gelagert ist. Vorteilhafte Weiterbildungen sind in den weiteren Ansprüchen angegeben.The invention achieves this object by a combination of at least one wave generator and at least one flow generator, which together with a navigation unit, a central unit, a buoyancy and direction unit, at least one flow turbine with a vertical rotor and a mechanical blade adjustment in approximately vertical direction movable on a rigid axle are arranged, which is mounted on a resting on the seabed and there optionally anchored basis weight below the water surface pivotally. Advantageous developments are specified in the further claims.

Das gesamte Gerät könnte beispielsweise ein Gewicht von etwa 30 Tonnen aufweisen, es wird im Dreibis · Viersekundentakt entsprechend eines Wellenhubes von beispielsweise einem Meter auf und ab gesenkt, wodurch etwa 100 kW einwirken.The entire device could, for example, have a weight of about 30 tons, it is in Dreibis · Viersekundentakt corresponding to a shaft stroke of, for example, one meter up and down, causing about 100 kW act.
Die Strömungsgeneratoren
Die Zentraleinheit
Die schiffbautechnische Berechnung dieser Schwimmeinheit muss mit zunehmender Neigung mehr Gegenauftrieb erzeugen, d.h. eine Kraft, die entgegen den Kräften die durch eine Krängung durch Wind und Strömung hervorgerufen werden, ein aufrichtendes Moment erzeugt. Die Hydraulik des Wellengenerators
Die gesamte Anordnung wird ähnlich wie ein Seezeichen ausgebracht und enthält eine Achse sowie eine Befestigung mit schwenkbarem Gelenk am Meeresboden. Die Schwimmeinheit hält die Strömungsturbine auch bei Seegang auf gleichbleibender Tiefe im Wasser. Der Hydraulische Zylinder des Wellengenerators ist durch seine Länge in der Lage, den örtlichen Tidenhub in axialer Bewegung auszugleichen.The entire arrangement is deployed similar to a navigation mark and includes an axle and an attachment with pivoting joint on the seabed. The floating unit keeps the flow turbine at constant depth in the water, even in rough seas. The length of the hydraulic cylinder of the shaft generator makes it possible to compensate for the local tidal movement in axial movement.
