Abstract

A powered buoy (1) which simultaneously utilizes wave- and solar energy in a device for generating renewable energy and through which the economy is increased relative to separate units. On the top surface of the powered buoy is located a wind wheel, which is specifically designed as a conventional Darrieus wind wheel (2).

Description

Die Kraftboje (1), Fig. 1 und Fig. 2, nützt zugleich die Energie des Windes, der Meereswellen und der Sonnenstrahlung aus. Durch die Kombination ergibt sich eine Erhöhung der Leistung des Gerätes gegenüber konventionellen Anlagen zur Erzeugung erneuerbarer Energie, die jeweils nur eine dieser Energiequellen ausnützen, und damit eine Verbesserung der Wirtschaftlichkeit.The power buoy ( 1 ), Fig. 1 and Fig. 2, uses the energy of the wind, the ocean waves and the solar radiation at the same time. The combination results in an increase in the performance of the device compared to conventional systems for generating renewable energy, which only use one of these energy sources, and thus an improvement in efficiency.

An der Oberseite der im Meer schwimmenden Kraftboje befindet sich ein Windrad (2), Fig. 1 und Fig. 2, vorzugsweise in der als Darrieus-Windrad bekannten Ausführung, das die Windenergie ausnützt. Dieses Darrieus-Windrad kann aus 3 Elementen (3), Fig. 1, bestehen, die an 3 Streben (4), Fig. 1, befestigt sind. Diese 3 Streben sind mit Drähten (5), Fig. 1, verspannt, um den mitdrehenden Masten (6), Fig. 1, zu stützen. Die 3 Elemente des Windrades sind mit Spanndrähten (7), Fig. 1, am Masten gehalten, welche die Fliehkräfte aufnehmen. Das Windrad kann einen getrennten Stromgenerator oder einen gemeinsamen Generator antreiben, der auch von der Hydraulik mit der Wellenenergie angetrieben wird. Eine automatische Bremse, die mit Drucköl aus dem Druckölspeicher (13), Fig. 2, betätigt sein kann, arretiert das Windrad bei einem Orkan, um es vor Beschädigung zu schützen.Is located at the top of floating in the sea Kraftboje a wind turbine (2), Fig. 1 and Fig. 2, preferably in the well known as a Darrieus wind turbine design that takes advantage of the wind energy. This Darrieus wind turbine can consist of 3 elements ( 3 ), Fig. 1, which are attached to 3 struts ( 4 ), Fig. 1. These 3 struts are braced with wires ( 5 ), Fig. 1, to support the rotating masts ( 6 ), Fig. 1. The 3 elements of the wind turbine are held on the mast with tension wires ( 7 ), Fig. 1, which absorb the centrifugal forces. The wind turbine can drive a separate power generator or a common generator, which is also driven by the hydraulics with the shaft energy. An automatic brake, which can be actuated with pressure oil from the pressure oil reservoir ( 13 ), FIG. 2, locks the wind turbine in the event of a hurricane in order to protect it from damage.

An der Unterseite ist die Kraftboje mit einer Hydraulik ausgestattet, die mit der Energie der Auf- und Abbewegung der Kraftboje Drucköl erzeugt, das einen Stromgenerator antreibt.At the bottom, the power buoy is equipped with a hydraulic system that uses the energy the up and down movement of the power buoy produces pressure oil which is a power generator drives.

Ein mit einem inneren Führungsrohr (8), Fig. 1, im äußeren Führungsrohr (9), Fig. 1, der Kraftboje gleitender, vorzugsweise topfförmiger Gegenkörper (10), Fig. 1, mit mitbewegter Wassermasse, die eine Vergrößerung des dynamischen Widerstandes bewirkt, erzeugt durch den Wasserwiderstand, ähnlich wie ein Treibanker, und durch seine Masse die nötige Gegenkraft, so daß der Kolben (11), Fig. 2, im doppelt­ wirkenden Hydraulikzylinder (12), Fig. 1 und Fig. 2, bei der Bewegung der Kraftboje Drucköl pumpt. In einer anderen Ausführung wird anstelle des Öles eine andere Flüssigkeit oder ein Gas verwendet, also Pneumatik statt Hydraulik.One with an inner guide tube ( 8 ), Fig. 1, in the outer guide tube ( 9 ), Fig. 1, the power buoy sliding, preferably cup-shaped counter body ( 10 ), Fig. 1, with moving water mass, which causes an increase in dynamic resistance , generated by the water resistance, similar to a sea anchor, and by its mass the necessary counterforce, so that the piston ( 11 ), Fig. 2, in the double-acting hydraulic cylinder ( 12 ), Fig. 1 and Fig. 2, during movement the power buoy pumps up pressure oil. In another embodiment, a different liquid or gas is used instead of the oil, i.e. pneumatics instead of hydraulics.

Ein Hydromotor mit verstellbarem Hubvolumen treibt den mit konstanter Drehzahl lufenden Stromgenerator. Dabei paßt er seine Druckölaufhahme an die periodisch schwankende Ölförderung des Kolbens (11), Fig. 2, an. Ein Druckölspeicher (13), Fig. 2, und ein Schwungrad (14), Fig. 2, sorgen für eine zusätzliche Glättung der Drehzahl, also für eine Verringerung deren periodischer Schwankung.A hydraulic motor with an adjustable displacement drives the power generator, which runs at a constant speed. He adjusts his pressure oil absorption to the periodically fluctuating oil production of the piston ( 11 ), Fig. 2. A pressure oil reservoir ( 13 ), Fig. 2, and a flywheel ( 14 ), Fig. 2, provide an additional smoothing of the speed, that is, to reduce its periodic fluctuation.

Anstelle eines Hydromotors mit verstellbarem Hubvolumen können auch mehrere Hydromotoren mit konstantem Hubvolumen (15), Fig. 2, angeordnet sein, die den Generator über ein Zahnrad (16), Fig. 2, antreiben. Instead of a hydraulic motor with an adjustable stroke volume, several hydraulic motors with a constant stroke volume ( 15 ), FIG. 2, can be arranged, which drive the generator via a gear wheel ( 16 ), FIG. 2.

Diese Hydromotoren werden entsprechend der periodisch schwankenden Drucköl­ förderung zugeschaltet und weggeschaltet, vorzugsweise von einer Mikroprozessor­ steuerung. Eine druckölbesufschlagte Kupplung bewirkt, daß sich die Hydromotoren nur dann drehen, wenn die mit Drucköl beaufschlagt sind und jeweils stillstehen, wenn sie drucklos geschaltet sind.These hydraulic motors are designed according to the periodically fluctuating pressure oil funding switched on and off, preferably by a microprocessor control. A clutch with pressure oil causes the hydraulic motors only turn when they are pressurized with oil and stand still when they are depressurized.

Die Kraftboje kann die Form einer flachen runden Scheibe haben, deren Durchmesser etwa die zwanzigfache Dicke ist. Dadurch wird bewirkt, daß die Kraftboje der Auf- und Abbewegung der Mereswellen folgt daher über die Hydraulik Energie aus dieser Wellenbewegung abgibt.The power buoy can have the shape of a flat round disc, the diameter of which is about twenty times the thickness. This causes the power buoy to rise and fall Movement of the meres waves therefore follows energy from the hydraulics Emits wave motion.

Die flache runde Scheibe hat außerdem eine große sonnenbeschienene Oberfläche, auf der zusätzlich Sonnenenergie erzeugt werden kann. Eine im Kreis umlaufende und zugleich rotierende Bürste (17), Fig. 1, und ein umlaufender Scheibenwischer (18), Fig. 1, sorgen für die automatische Reinigung der Solarenergiefläche.The flat, round disc also has a large sunlit surface on which additional solar energy can be generated. A rotating and rotating brush ( 17 ), Fig. 1, and a rotating wiper ( 18 ), Fig. 1, ensure the automatic cleaning of the solar energy surface.

Außerdem ergibt die flache Scheibe ein stabiles Schwimmverhalten, das die nötige aufrechte Stellung des Windrades sicherstellt. Diese Schwimmstabilität wird durch den Gegenkörper (10), Fig. 1, wegen seines Gewichtes und wegen seines Wasserwider­ standes verstärkt.In addition, the flat disc results in a stable swimming behavior, which ensures the necessary upright position of the wind turbine. This swimming stability is reinforced by the counter body ( 10 ), Fig. 1, because of its weight and because of its water resistance.

Der Gegenkörper wird mit einer Schraubenfeder (19), Fig. 1, in der mittleren Stellung gehalten. Er ist spezifisch schwerer als das Wasser, so daß ein Teil seines Gewichtes von der Kraftboje gehalten wird. Das bewirkt eine Erhöhung der Schwimmstabilität der Kraftboje.The counter body is held in the middle position with a helical spring ( 19 ), Fig. 1. It is specifically heavier than water, so that part of its weight is held by the power buoy. This increases the swimming stability of the power buoy.

Durch Abstimmung der Federsteifigkeit der Schraubenfeder (19), Fig. 1, kann eine gedämpfte angeregte Resonanzschwingung erzeugt werden, wodurch der Kolbenweg bei niedrigem Wellengang erhöht wird.By adjusting the spring stiffness of the coil spring ( 19 ), Fig. 1, a damped excited resonance vibration can be generated, whereby the piston travel is increased in low waves.

Der Hydraulikzylinder (12), Fig. 1 und Fig. 2, ist mit einer gewellten, dehnbaren Gummimanschette (29), Fig. 1 und Fig. 2, umgeben. Eine Ölfüllung (20), Fig. 2, verhindert, daß die Gummimanschette am Hydraulikzylinder bei der periodischen Kolbenbewegung reibt.The hydraulic cylinder ( 12 ), Fig. 1 and Fig. 2, is surrounded by a corrugated, stretchable rubber sleeve ( 29 ), Fig. 1 and Fig. 2. An oil filling ( 20 ), Fig. 2, prevents the rubber sleeve from rubbing on the hydraulic cylinder during the periodic piston movement.

Der Kolben des Hydraulikzylinders ist am oberen und am unteren Anschlag mit einer hydraulischen Dämpfung versehen. Diese bewirkt eine Begrenzung der Anschlagkräfte, wenn bei einem Orkan die Höhe der Meereswellen größer ist als der Kolbenhub, so daß die Kraftboje periodisch untertaucht und aus dem Wasser vollkommen auftaucht.The piston of the hydraulic cylinder is with a at the upper and lower stop provided hydraulic damping. This limits the impact forces, if in a hurricane the height of the sea waves is greater than the piston stroke, so that the power buoy is submerged periodically and emerges completely from the water.

Durch Polumschaltung kann die Generatordrehzahl an die augenblickliche Windstärke und Wellenstärke angepaßt werden.By changing the pole, the generator speed can be adjusted to the current wind speed and wave strength can be adjusted.

Der erzeugte Strom kann direkt zum Verbraucher geleitet oder vor Ort zur Erzeugung von Wasserstoff verwendet werden. Dieser kann dann mit Rohrleitungen oder mit Schiffen zum Verbraucher transportiert werden.The electricity generated can be sent directly to the consumer or on site for generation of hydrogen can be used. This can then be done with pipes or with Ships are transported to the consumer.
