Description

Die Erfindung bezieht sich auf eine Anordnung für ein Meereswellenkraftwerk nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an arrangement for a marine wave power plant according to the preamble of patent claim 1.

Im Stand der Technik sind viele derartige Anordnungen beschrieben. Da der Bau von Windenergieanlagen an Land durch strengere Auflagen immer kritischer beurteilt wird, will man in zunehmendem Maße Windenergieanlagen auf offener See installieren die die kinetische Energie von Wellenbewegungen in elektrische Energie umwandeln. In der Vergangenheit wurden weltweit viele Systeme entwickelt von denen sich aber wegen der extremen Bedingung im Onshore und Offshore Bereich bisher keines in Serie durchsetzen konnte und mussten in nahezu allen Fällen bereits in der Testphase aufgegeben werden.Many such arrangements are described in the prior art. Since the construction of onshore wind turbines is being assessed more and more critically by stricter requirements, it is increasingly planned to install wind turbines on the open sea, which convert the kinetic energy of wave motions into electrical energy. In the past, many systems were developed worldwide, of which, however, due to the extreme conditions in the onshore and offshore area, none of them has been able to assert themselves in series and in almost all cases had to be abandoned in the test phase.

Aufgabe der Erfindung ist es daher ein Kraftwerk vorzustellen, welches die Energieauskopplung aus Meereswellen mit geringstem technischem Aufwand ermöglicht und dessen Standzeit und technischer Wirkungsgrad in einem hocheffektivem gesamtwirtschaftlichen Verhältnis zu den Anlagekosten stehen, denn nicht immer ist eine vermeintlich technisch aufwendigere Konstruktion auch unter Berücksichtigung der Investitions- und Instandhaltungskosten langfristig effizienter.The object of the invention is therefore to introduce a power plant, which allows the energy extraction from sea waves with the least technical effort and its life and technical efficiency in a highly effective overall economic relationship with the investment costs, because not always is a supposedly more technically complicated construction, taking into account the investment and maintenance costs more efficient in the long term.

In folgendem wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit zwei Zeichnungen beschrieben.In the following the invention will be described with reference to a preferred embodiment in conjunction with two drawings.

Dabei zeigt:

  • 1 eine vereinfachte Schnittzeichnung des Meereswellenkraftwerk (1) Vorderansicht. Um möglichst wirtschaftlich zu arbeiten dient der Turm (17) gleichzeitig als Zylinder für den darin eintauchenden Kolben (14) der mit Meerwasser geschmiert wird. Bei einer Hubphase des Kolbens (14) strömt das Meerwasser über das Einlassventil (13) in den Druckraum (12) und wird beim Niederfahren des Kolbens (14) über das Auslassventil (11) und die Druckleitung (10) in die Turbine (8) gedrückt und es wieder über den Auslauf (9) verlässt. Der Auftriebskörper (5) ist mittels der Fördergabel (4) mit dem Gelenk (3) und dem um mehr als 360° verdrehbarem Drehdeckel (18) unverlierbar verbunden, wobei das Gelenk 16 als Kugelgelenk (16) oder Kardangelenk ausgeführt ist. Vorteilhafterweise dreht sich der Auftriebskörper (5) automatisch in die Wellenrichtung und wird somit mechanisch weniger beansprucht. Der Generator (7) ist zum Schutz vor Meerwasser, Regen und Frost im Generatorschutzraum (6) platziert von wo auch das Energiekabel ausgeführt wird.
  • 2 eine vereinfachte Schnittzeichnung des Meereswellenkraftwerk (1) Vorderansicht bei dem durch die Erweiterung eines zweiten Druckraumes (26) mit einem zweiten Kolben (25) sowohl der Hub als auch die Senkung des Auftriebskörpers (5) zum Energieeintrag beiträgt. Hierzu wird der Druckraum (12) und der Druckraum (26) durch die Trennscheibe (21) getrennt, wobei die Kolbenstange (20) die beiden Kolben kraftschlüssig verbindet durch die Bohrung (22) läuft. Die Kolbenstange (20) muss nicht in Gleitreibung durch die Bohrung (22) laufen sondern kann einen geringfügig kleineren Durchmesser aufweisen da Gleitdichtungen über mehr als zwei Elemente relativ anfällig sind. Der Ausgleich hierfür liegt in der großen Differenz der dynamischen Widerstandssituation der Ringfläche der Bohrung (22) zu den Ventilen. Über das Leckwasserventil (24) wird das Leckwasser beim Niederfahren des Kolbens (25) aus dem Druckraum (26) befördert.
Showing:
  • 1 a simplified sectional drawing of the marine wave power plant (1) front view. In order to work as economically as possible, the tower (17) serves as a cylinder for the immersing piston (14) which is lubricated with seawater. In a stroke phase of the piston (14), the seawater flows via the inlet valve (13) in the pressure chamber (12) and is when lowering the piston (14) via the outlet valve (11) and the pressure line (10) in the turbine (8). pressed and leaves it again via the outlet (9). The buoyancy body (5) is connected by means of the conveyor fork (4) to the joint (3) and rotatable by more than 360 ° rotary cover (18) captive, wherein the joint 16 is designed as a ball joint (16) or universal joint. Advantageously, the buoyancy body (5) rotates automatically in the direction of the shaft and is therefore subjected to less mechanical stress. The generator (7) is placed to protect against seawater, rain and frost in the generator protection room (6) from where the power cable is running.
  • 2 a simplified sectional view of the marine wave power plant (1) front view in which contributes by the expansion of a second pressure chamber (26) with a second piston (25) both the stroke and the lowering of the buoyancy body (5) for energy input. For this purpose, the pressure chamber (12) and the pressure chamber (26) separated by the cutting disc (21), wherein the piston rod (20) connects the two pistons frictionally through the bore (22). The piston rod (20) need not be in sliding friction through the bore (22) but may have a slightly smaller diameter because sliding seals are relatively susceptible to more than two elements. The compensation for this lies in the large difference between the dynamic resistance situation of the annular surface of the bore (22) to the valves. About the leak water valve (24) the leak water is conveyed when driving down the piston (25) from the pressure chamber (26).
