Abstract
Description
In der beigefügten Abbildung Seite 8 ist ein Element des
Strömungskraftwerkes beispielhaft folgendermaßen dar
gestellt:
Der Rotor ist mit (1) bezeichnet und trägt den als Pro
peller wirkenden Leitflächenkranz (2), der bei der darge
stellten Anströmungsrichtung Pfeil (9) den Rotor (1) gemäß
Pfeil (8) in Umdrehung versetzt. Der Rotor (1) trägt etwa
bei (3) einen Auftriebskörper und setzt sich in den nur an
gedeuteten Generator-Rotor (4) fort, der in dem punktiert
gezeichneten Stator (6) rotieren kann und bei (5) in be
kannten Lagern so gelagert ist, daß die von der Strömung
hervorgerufenen Kräfte über die zentrale Befestigung (7)
auf die Verankerung übertragen werden. Die Verankerung
besteht aus dem elastischen, aber nicht um seine Längs
achse drehbaren Verbindungsteil (10), das fest mit dem
im Gewässergrund (11) angebrachten Betonanker (12) verbun
den ist.In the attached figure on page 8, an element of the flow power plant is shown as an example:
The rotor is designated ( 1 ) and carries the per-peller guide ring ( 2 ), which in the flow direction shown Darge arrow ( 9 ) rotates the rotor ( 1 ) according to arrow ( 8 ) in rotation. The rotor ( 1 ) carries approximately at ( 3 ) a buoyancy body and continues in the only indicated generator rotor ( 4 ), which can rotate in the dotted stator ( 6 ) and at ( 5 ) in known bearings is mounted that the forces caused by the flow are transmitted to the anchor via the central fastening ( 7 ). The anchoring consists of the elastic, but not about its longitudinal axis rotatable connecting part ( 10 ), which is firmly connected to the concrete anchor ( 12 ) attached in the body of water ( 11 ).
Der Rotor kann jede andere zweckmäßige Form haben, also auch ein relativ zum Durchmesser langer Kunststoff-Schlauch sein, der größtenteils mit Wasser und nur teilweise wegen des Auftriebs mit Luft gefüllt ist, wenn außer der Ener gieerzeugung ein erhöhter Strömungswiderstand zwecks Energievernichtung erforderlich sein sollte.The rotor can have any other convenient shape, that is also a plastic hose that is long relative to the diameter be mostly water and only partly because the buoyancy is filled with air when except the ener gie generation an increased flow resistance in order Energy destruction should be required.
Es wird erfindungsgemäß auch die Möglichkeit eingeschlos sen, den Generator in den Grundanker zu integrieren, wobei sodann Auftriebskörper mit Leitflächen und Verbindungs teil eine Einheit bilden, die das hydrodynamisch erzeugte Drehmoment auf den Generator-Rotor überträgt. According to the invention, the possibility is also included sen to integrate the generator into the base anchor, whereby then buoyancy body with guide surfaces and connection form part of a unit that the hydrodynamically generated Transmits torque to the generator rotor.
Die Nutzung der kinetischen Energie strömender Gewässer erfolgt allgemein in der Weise, daß man natürlich oder künstlich bis zu einer gewissen Höhe aufgestautes Wass er mittels Schaufelrädern oder Turbinen, die mit elek trischen Generatoren gekoppelt sind, mit der Erzeugung elektrischer Energie Arbeit leisten läßt.The use of the kinetic energy of flowing water is generally done in such a way that one of course or water artificially dammed up to a certain height by means of paddle wheels or turbines, which are connected to elec trical generators are coupled with the generation electrical energy.
Die zu diesem Zwecke erforderlichen Kraftwerksbauten sind den jeweiligen topographischen und hydraulischen Gegebenheiten des zu nutzenden Gewässers stets indivi duell anzupassen, sind aufwendig in der Ausführung und lassen sich nachträglich kaum ändern, wenn andere Gege benheiten dies erforderlich machen.The power plant buildings required for this purpose are the respective topographical and hydraulic The conditions of the water to be used are always individual duel, are complex to implement and can hardly be changed afterwards if other areas make this necessary.
So erscheint zum Beispiel die Nutzung der weitgehend konstanten West-Ost-Strömung in der Straße von GIBRAL TAR, mit ihrer enormen Förderung von etwa 80 000 Kubik metern pro Sekunde, unmöglich mit konventionellen Mit teln realisierbar.For example, the use of the appears largely constant west-east flow in the street of GIBRAL TAR, with its enormous output of around 80,000 cubic meters meters per second, impossible with conventional Mit feasible.
Demgegenüber war es jedoch vorübergehend gelungen, in der recht engen Meeresbucht von SAINT MALO (Frankreich) ein funktionierendes Kraftwerk zu errichten, das den dortigen erheblichen Tiden-Hub ausnutzt. Bei Flut wur de das Wasser durch große Schleusen in einen Speicher geleitet, um es umgekehrt bei einsetzendem Ebbestrom über Niederdruck-Turbinen mit elektrischen Generatoren Arbeit leisten zu lassen.In contrast, however, it had temporarily succeeded in the rather narrow bay of SAINT MALO (France) to build a functioning power plant that exploits significant tidal range there. At high tide de the water through large locks into a reservoir directed to it the other way around when ebb flow begins via low pressure turbines with electrical generators To have work done.
Die gewaltigen Tidenströmungen der Erde, die viermal täg lich ihre Richtung ändernd, in Watten-Gebieten und Flußdeltas auftreten, lassen sich mit den bekannt gewordenen Mitteln in nennenswerter Weise überhaupt noch nicht zur Erzeugung elektrischer Energie nutzen, weil die nutzbaren Strömungen zu weit vom Ufer entfernt liegen und weil nautische Verhältnisse, wie auch ständig sich ändernde Sedimentation und Erosion an Ufern und Gewässergrund die Anlage konventioneller Kraftwerksbauten ausschließen.The mighty tidal currents of the earth, four times a day Lich changing direction, in wadden areas and river deltas can occur with those who have become known Not worth mentioning funds at all Use electrical energy generation because the usable Currents are too far from the bank and because nautical conditions, as well as constantly changing Sedimentation and erosion on the banks and the bottom of the water Exclude the installation of conventional power plants.
Durch die Patentanmeldung P 38 19 194.6 ist ein Mittel be kannt geworden, mit welchem jedem beliebigen und schwier igen Gewässerstrom durch bojenartige, an individuellen Ankern befestigte Widerstandskörper, kinetische Ström ungsenergie entzogen werden kann.Through the patent application P 38 19 194.6 is a means became known with which any and difficult water flow through buoy-like, individual Anchor fixed resistance bodies, kinetic flow energy can be extracted.
Diese Energievernichtung kann praktisch an jeder gewünsch ten Stelle des strömenden Wasserkörpers, durch die hydro dynamischen Eigenschaften des Widerstandskörpers bedingt, so portioniert werden, daß die Übertragung der Gegen kräfte auf jedweden Gewässergrund unproblematisch ist.This energy destruction can be practically desired on everyone th place of the flowing body of water through which hydro dynamic properties of the resistance body, be portioned so that the transfer of the counter forces on any water bed is unproblematic.
Die in großer Zahl in einer Strömung angeordneten bojen artigen Widerstandskörper leiten - analog den Verhält nissen bei einem durchströmten Schilffeld - individuell die Gegenkraft ihres Strömungswiderstandes über die Ver ankerung in den Grund ab, wobei einzeln ein sehr geringer Aufstau des Wassers erfolgt, der sich insgesamt addiert und zur Abnahme der Strömungsgeschwindigkeit führt. Die Folge ist die Reduktion der pro Zeiteinheit transportier ten Wassermenge, so daß , ganz im Sinne des Kostenschutzes, bei Flut an den Seedeichen der Wattengebiete geringere Höchstwasserstände nur auftreten können.The buoys arranged in large numbers in a current conduct like resistance body - analogous to the ratio nissen in a reed field with flow - individually the counterforce of their flow resistance over the ver anchoring in the ground, whereby individually a very small one Water is accumulated, which adds up overall and leads to a decrease in flow velocity. The The result is a reduction in the amount of time transported amount of water, so that, in the spirit of cost protection, lower at flood on the dikes of the wadden areas Maximum water levels can only occur.
Es ist naheliegend, nicht nur kinetische Energie durch eine derartige Anordnung zu vernichten, sondern sie im Gegenteil auch mit bekannten Mitteln zu nutzen, was Gegen stand vorliegender Erfindung ist.It is obvious not just through kinetic energy to destroy such an arrangement, but in On the contrary, to use what is known was present invention.
