Abstract
(DE)
Beschrieben wird eine Vorrichtung (1) zur Umwandlung von Wellenenergie in elektrische Energie mit einer von einem schwimmenden Objekt getragenen Pumpeinrichtung (1), die einen in einem Pumpraum (2) angeordneten, frei entlang einer Längsachse (L) des Pumpraums (2) beweglichen Verdrängungskörper (3, 4) aufweist, welcher den Pumpraum (2) in zwei Teilräume trennt. Die beiden Teilräume sind durch ein Verbindungsleitungssystem (10) untereinander verbunden. An das Verbindungsleitungssystem (10) ist ein Generator (22) angeschlossen. Die Pumpeinrichtung ist so ausgelegt, dass aufgrund einer durch Wellen erzeugten horizontalen Schaukelbewegung des Pumpraums (2) dieser um eine quer zu seiner Längsachse (L) verlaufende horizontale Achse schwingt, wobei der Mittelwert der Lage der Längsache (L) im wesentlichen horizontal ausgerichtet ist. Dabei wird der Verdrängungskörper (3, 4) im Pumpraum (2) hin und her bewegt und drückt ein Pumpmedium (30), welches den Generator (22) antreibt, durch das Verbindungsleitungssystem (10).
(EN)
The invention relates to a device (1) for converting wave power to electric power. The inventive device comprises a pump device (1) that is carried by a floating object, said pump device being provided with a displacement body (3, 4) mounted in a pump chamber (2) and freely displaceable along a longitudinal axis (L) of said pump chamber (2), and dividing the pump chamber (2) into two subchambers. Said subchambers communicate by way of a connecting line system (10). A generator (22) is connected to said connecting line system (10). The pump device is designed in such a manner that a horizontal rocking movement of the pump chamber (2) caused by the waves induces said pump chamber to oscillate about a horizontal axis that is transverse to its longitudinal axis (L), the average value of the position of the longitudinal axis (L) being substantially horizontal. The displacement body (3, 4) is moved back and forth in the pump chamber (2) and forces a pump medium (30) that drives the generator (22) through the connecting line system (10).

L'invention concerne un dispositif (1) pour convertir l'énergie de la houle en énergie électrique, comportant une unité de pompage (1) qui est portée par un objet flottant et qui présente une corps de refoulement (3, 4) placé dans une chambre de pompage (2) et pouvant se déplacer librement le long d'un axe longitudinal (L) de la chambre de pompage (2). Ce corps de refoulement sépare la chambre de pompage (2) en deux chambres partielles communiquant par l'intermédiaire d'un système de conduite de raccordement (10) auquel est raccordé un générateur (22). L'unité de pompage est conçue de sorte que, en raison d'un mouvement de bascule horizontal de la chambre de pompage (2), produit par la houle, ladite chambre de pompage (2) oscille autour d'un axe pratiquement horizontal s'étendant transversalement à son axe longitudinal (L). La valeur moyenne de la position de l'axe longitudinal (L) est orientée pratiquement horizontalement. Le corps de refoulement (3, 4) est animé d'un mouvement alternatif dans la chambre de pompage (2) et refoule à travers le système de conduite de raccordement (10) un agent de pompage (30) qui entraîne le générateur (22).
