Ein Schiff (geeigneter Tanker ect.) ist in Ufernähe ver ankert. Seitlich an der Außenseite der Bordwand zur offe nen See hin, sind vertikal beweglich zwei Auslegerarme (1+2) angebracht und entgegengesetzt auf einem Schwimmer (3) befestigt. Zwischen den Auslegerarmen (1+2) ist ein beweglicher Zylinder (4) in der Aufhängung (11) gelagert. Von diesem Zylinder führt nach oben ein Kolben (5) der dort befestigt ist. Vertikal an der Bootswand sind zwei von oben bis nach unten ins Wasser reichende kräftige Schraubspindeln (6, 7) drehbar gelagert. An höhenmäßig verstellbaren Muttern (8, 9, 10) an den Spindeln sind in einem bestimmten Abstand zueinander, Kolben (5) sowie die beiden Auslegerarme (1, 2) und Zylinderführungen (24) be festigt. Die Höhen- bzw. Tiefeneinstellung der Zylinder konstruktion (4, 5) ist so gewählt, daß der Zylinder (4) voll unter Wasser zu liegen kommt. Beide Spindeln sind dabei Syncron zu betreiben.A ship (suitable tanker etc.) is anchored near the shore. Laterally on the outside of the dropside towards the open sea, two cantilever arms ( 1 + 2 ) are vertically movable and attached opposite to a float ( 3 ). A movable cylinder ( 4 ) is mounted in the suspension ( 11 ) between the boom arms ( 1 + 2 ). From this cylinder leads a piston ( 5 ) which is attached there. Two strong screw spindles ( 6 , 7 ) reaching vertically from top to bottom into the water are rotatably mounted vertically on the boat wall. On height-adjustable nuts ( 8 , 9 , 10 ) on the spindles at a certain distance from each other, piston ( 5 ) and the two cantilever arms ( 1 , 2 ) and cylinder guides ( 24 ) be fastened. The height or depth setting of the cylinder construction ( 4 , 5 ) is chosen so that the cylinder ( 4 ) comes to lie completely under water. Both spindles are to be operated synchronously.
Beim Wellengang gehorcht der Schwimmer (3) der Wellenbe wegung, wobei der Zylinder (4) gehoben und über den fest stehenden Kolben (5) gedrückt wird. An der Unterseite des Zylinders (4) befindet sich eine Einlaßöffnung (12) mit Kugelventil (13) und vorgelagertem Schmutzkorb (14). Auch an der Unterseite des Kolbens (5) befindliche Einlaßöffnung (15) mit Kugelventil (16) garantieren ein exaktes Öffnen und schließen der Einlaßöffnungen (12, 15). Durch das Unter wassersetzen des Arbeitszylinders (4) ist erstens eine Auf nahme von Luft mit dem einströmenden Wasser in die Einlaß öffnung (12) mit vorgelagertem Schmutzkorb unmöglich, die die Druckleistung negativ beeinflussen würde und zweitens wirkt sich das Gewicht des im Zylinder (4) befindlichen Wassers in der Arbeitsleistung nicht nachteilig aus und ist gleich Null. Schon bereits eine geringe vertikale Be wegung des Schwimmers (3) durch den Wellengang begründet, schließt das Einlaßventil (12) und führt zur Pumpleistung. When the waves swell ( 3 ) obeys the movement, the cylinder ( 4 ) is lifted and pressed over the fixed piston ( 5 ). At the bottom of the cylinder ( 4 ) there is an inlet opening ( 12 ) with a ball valve ( 13 ) and an upstream dirt basket ( 14 ). Inlet opening ( 15 ) with ball valve ( 16 ) located on the underside of the piston ( 5 ) also guarantees exact opening and closing of the inlet openings ( 12 , 15 ). By putting the working cylinder ( 4 ) under water, firstly, an intake of air with the inflowing water into the inlet opening ( 12 ) with an upstream dirt basket is impossible, which would have a negative impact on the pressure output, and secondly, the weight of the cylinder ( 4 ) water in the work performance is not disadvantageous and is zero. Already a slight vertical movement of the float ( 3 ) due to the swell, the inlet valve ( 12 ) closes and leads to pumping power.
Kolben (5) sowie auch Zylinder (4) sind ca. 15° schräg zur Schraubspindel (6, 7) aufgehängt, sodaß eine günstige Hebel wirkung bei den beweglichen Teilen am Auslegerarm (21, 11) bewerkstelligt ist und die Wirkung der Schubkraft von Zy linder (4) zu Kolben (5) auf die obere Halterung (23) und zu den Schraubspindeln geführt wird. Am unteren Teil des Zylinders (4) ist vertikal drehbar eine Führung (24) ange bracht, die bei der Arbeitsbewegung des Zylinders diesen genau linear zum Kolben führt. Dazu sind die Abstände von Aufhänge- bzw. zu Führungsbolzen (21, 11) und (25, 26) gleich. Desgleichen auch Abstand (21, 25) und (11, 26). Die Kolben aufhängung (23) ist auch drehbar gelagert um die leichte Drehbewegung aufzunehmen, die im Radius (21, 11) entsteht. Das vom nach oben gehenden Zylinder (4) gedrückte Wasser öffnet das Kugelventil am Kolbenboden (16) und füllt über die Zuleitungen im Kolbeninneren und beweglichen Druck schlauch (17) einen Wasserdruckbehälter (18), der im Schiffsrumpf installiert ist. Durch das einströmende Was ser wird die Luft im Wasserdruckbehälter (18) verdichtet und es entsteht bekanntlich der elastische Wasserdruck. Das so unter Druck gesetzte Wasser wird über eine Steig leitung (19) zu einer Turbine am Deck geleitet, die einen Generator zur Stromerzeugung treibt. Über ein Kabel wird an Land in das Stromnetz gespeist.Piston ( 5 ) and cylinder ( 4 ) are suspended approximately 15 ° to the screw spindle ( 6 , 7 ), so that a favorable lever effect is achieved with the moving parts on the extension arm ( 21 , 11 ) and the effect of the thrust of Zy Linder ( 4 ) to piston ( 5 ) on the upper bracket ( 23 ) and to the screw spindles. At the lower part of the cylinder ( 4 ) a guide ( 24 ) is vertically rotated, which leads to the piston during the working movement of the cylinder exactly linear. For this purpose, the distances from the suspension bolts to the guide bolts ( 21 , 11 ) and ( 25 , 26 ) are the same. Likewise also distance ( 21 , 25 ) and ( 11 , 26 ). The piston suspension ( 23 ) is also rotatably mounted to absorb the slight rotary movement that occurs in the radius ( 21 , 11 ). The water pushed up by the cylinder ( 4 ) opens the ball valve on the piston crown ( 16 ) and fills via the supply lines inside the piston and the movable pressure hose ( 17 ) a water pressure tank ( 18 ) which is installed in the ship's hull. Due to the inflowing water, the air in the water pressure container ( 18 ) is compressed and, as is known, the elastic water pressure is created. The water pressurized in this way is fed via a riser ( 19 ) to a turbine on the deck, which drives a generator to generate electricity. A cable is fed into the power grid on land.
Bei der Abwärtsbewegung des Schwimmers (3) ins Wellental genügt das Gewicht der bewegten Teile, das geschlossene Kugelventil (13) wieder zu öffnen und den Zylinder (4) zu füllen. Die Kugel (13) ist nur geringfügig schwerer als Wasser.When the float ( 3 ) moves downwards into the trough, the weight of the moving parts is sufficient to open the closed ball valve ( 13 ) again and to fill the cylinder ( 4 ). The ball ( 13 ) is only slightly heavier than water.
Ein Vorteil dieser Anlage besteht darin, das die Wellen energie gespeichert werden kann. Bei höherem Wellengang kann eine Überkapazität der Pumpleistung in mehrere hin tereinander geschaltete Wasserdruckbehälter im Rumpfin neren des Schiffes gespeist werden die bei Unterversor gung wieder dazugeschaltet werden. Zudem können mehrere Pumpanlagen nebeneinander am Schiff installiert werden die eine ausreichende Versorgung gewährleisten. Bei stürmischem Wellengang kann das Schiff bis zu 180° abgedreht werden, weil durch die untere Abschrägung des Schwimmers (3) auch bei seitlich anströmenden Wellen ein guter Aufwärtsdruck ge währleistet ist. Selbst bei Situationen bei der um 180° zur Brandung abgewandten Pumpanlage führt die Schaukelbewegung des Schiffes noch zur Pumpleistung. Außer den Wasserdruck kesseln sind im Rumpf des Schiffes noch ein oder mehrere Luftdruckkessel installiert, die mittels Luftkompressor ge füllt werden. Bei Unterversorgung des gepumpten Wassers kann der abnehmende Druck im Wasserdruckkessel damit er gänzt und der gleichmäßige Wasserdruck auf die Turbine ge währleistet werden.Bei höherer Pumpleistung wird bei ent stehendem Überdruck im Wasserdruckbehälter die überver dichtete Luft wieder in den Luftdruckkessel abgedrängt.An advantage of this system is that the wave energy can be stored. When the waves are higher, an overcapacity of the pumping capacity can be fed into several water pressure tanks connected in series in the interior of the ship's hull, which can be switched on again if there is insufficient supply. In addition, several pumping systems can be installed next to each other on the ship to ensure adequate supply. In stormy waves, the ship can be turned up to 180 °, because the lower bevel of the float ( 3 ) ensures good upward pressure even with waves coming in from the side. Even in situations with the pumping system turned away from the surf by 180 °, the rocking movement of the ship still leads to pumping performance. In addition to the water pressure boilers, one or more air pressure boilers are installed in the hull of the ship, which are filled using an air compressor. If the pumped water is undersupplied, the decreasing pressure in the water pressure boiler can be supplemented and the even water pressure on the turbine can be guaranteed. With higher pump power, if the pressure in the water pressure tank is too high, the over-compressed air is forced back into the air pressure boiler.
Man könnte sogar bei vollkommen ruhiger See Wasserbehälter, die im Schiffsrumpf tiefer als der Meereswasserspiegel in stalliert sind drucklos befluten um sie dann nachträglich durch Lultdruckkessel unter Druck zu setzen. Durch diese Einrichtungen ist es möglich größere Energiespeicherungen zu bewirken, die eine lückenlose Stromerzeugung ermögli chen.You could have water tanks even when the sea was completely calm, those in the hull lower than the sea water level in installed are pressurized and flooded afterwards pressurized by a pressure vessel. Through this Facilities allow larger energy storage to effect, which enable a seamless power generation chen.
Natürlich können derartige Anlagen auch an Steilküsten sta tionär gebaut werden die gut in der Strömung liegen.Of course, such systems can also be used on cliffs are built in a way that lies well in the current.
