Abstract

The generator uses a floating body (1) which cooperates with a second body (2,3) which oscillates relative to it, when the floating body is moved up and down by wave movement. The relative oscillation of the two bodies is converted into electrical energy. Pref. the second body comprises a stabilised, large dia plate (2) connected via vertical rods to two coupling plates (5,6) between which a pump (8) is located. The pump piston rod (9) is attached to the floating body, so that it moves up and down with the latter. The generator is held in position by at least one anchoring cable fixed to the seabed and to one of the coupling plates (5,6), and running at an angle of less than 45 deg. to the horizontal.

Description

"Meereswellenbetriebener Generator" "Ocean Wave Powered Generator"

Der Erfindung liegt die Aufgabe zugrunde, einen einfach ausgebildeten, betriebssicheren, einfach zu wartenden Meereswellengenerator zu schaffen. Der Generator kann eine Pumpe oder eine Einheit sein, die die Relativbewegungen in elektrische Energie umwandelt.The invention is based on the object of providing a simply designed, to create a reliable, easy-to-maintain ocean wave generator. The generator can be a pump or a unit that converts the relative movements into electrical Converts energy.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen auf der Wasseroberfläche schwimmenden ersten Körper und einem von diesen getragenen, in oder an ihm auf- und abbeweglich gelagerten zweiten Körper, der bezüglich seiner Bewegungen gehemmt ist, wobei die Relativbewegungen der beiden Körper zueinander zur Energiegewinnung ausgenutzt werden.According to the invention, this object is achieved by one on the surface of the water floating first body and one carried by these, in or on it- and second body, which can be displaced and which is inhibited with regard to its movements is, the relative movements of the two bodies to each other for energy generation be exploited.

Der Generator ist durch ein Seil am Meeresboden verankert, so daß er sich jeweils zur Windrichtung orientieren kann.The generator is anchored to the seabed by a rope so that he can orient himself to the wind direction.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung. Darin zeigen: Fig. 1 schematisch eine Seitenansicht der erfindungsgemäßen Vorrichtung und Fig. 2 eine perspektivische Darstellung derselben.Further details of the invention emerge from the drawing. 1 shows a schematic side view of the device according to the invention and FIG. 2 is a perspective view of the same.

In den Figuren ist mit 1 ein Schwimmer und mit 2 eine stabilisierende große Platte bezeichnet, 3 sind vertikale Stangen, die eine oberste Verbindungsplatte 4, sowie zwei weitere Platten 5 und 6 tragen. Versteifungsbleche 7 verstärken die Konstruktion und dämpfen den zweiten Körper gegenüber horizontalen Verschiebungen. Zwischen den Platten 5 un 6 ist eine-Pumpe 8 angebracht, in der ein Kolben 9 vom Schwimmer 1 hin-und herbewegt wird. Über Befestigungsösen Io wird die schwimmende Einheit über Seile 14 durch einen Bodenanker gehalten. Spiralfedern 11 halten den Schwimmer 1 elastisch in der Mittellage. 12 ist die Wasseroberfläche, 15 der Meeresgrund.In the figures, 1 is a float and 2 is a stabilizing float called large plate, 3 are vertical rods that form an uppermost connecting plate 4, as well as two further plates 5 and 6 carry. Stiffening plates 7 reinforce the Construction and dampen the second body against horizontal displacements. Between the plates 5 and 6 a pump 8 is attached, in which a piston 9 from Swimmer 1 back and forth is moved. Via fastening loops Io will the floating unit is held by ropes 14 by a ground anchor. Coil springs 11 hold the float 1 elastically in the central position. 12 is the surface of the water, 15 the bottom of the sea.

An Stelle der dynamischen Stabilisierung durch die grobe Platte 2 kann eine Trägheitsstabilisierung mit Hilfe einer flutbaren tonne erfolgen, wobei diese Tonne bei Wartungsarbeiten zum leichteren Einbringen der Energiewandlerboje bzw. zum Ausbringen mit Luft gefülit werden kann.Instead of dynamic stabilization by the coarse plate 2 inertial stabilization can be carried out with the aid of a floodable barrel, whereby this barrel for maintenance work to facilitate the introduction of the energy converter buoy or can be filled with air for application.

Eine weitere Ausführungsform, die insbesondere zur Nutzung auch der Energie niedriger Wellen geeignet ist, besteht darin, daß die Stangen 3 Hohlrohre sind, so daß der stabilisierte zweite Körper in seiner Arbeitsposition von selbst schwimmt. Der Schwimmer 1 ist dann ein Wellenfolger von geringem Eigengewicht und damit hoher Eigenfrequenz, der auch hohen Wellenfrequenzen folgt. Arbeitsgang ist dabei nur die Aufwärtsbewegung, so daß die Pumpe eine Einwegpumpe ist.Another embodiment, which is particularly useful for the Energy of low waves is suitable, is that the rods 3 hollow tubes are so that the stabilized second body in its working position by itself swims. The float 1 is then a wave follower of low weight and thus high natural frequency, which also follows high wave frequencies. Operation is only the upward movement, so that the pump is a one-way pump.
