Title (EN) WAVE-POWER PLANT WITH CONTROLLABLY BUOYANT FLOATS
(FR) CENTRALE HOULOMOTRICE À FLOTTEURS FLOTTANTS POUVANT ÊTRE COMMANDÉS
Abstract:
(EN) Floating wave power plant (100) comprises a shaft (102) provided with unidirectional rotary rotor blades (101). The shaft (102) is connected with a generator (233) arranged inside a generator housing (211) for the production of electric current. Two or more buoyancy means (106) are connected to the shaft (102), arranged to control depth level of the wave power plant (100) and angle of inclination of the shaft (102). The buoyancy means (106) is hollow and exhibits a bladder (133) attached to the interior of the housing (111) and encompassing the shaft (102), this defining a gas-filled interior (115) and a water-filled environment (114) inside the housing (111). The gas-filled interior (115) is emptied and filled by gas via conduit (118), valve (117) and conduit (116) and by means of a compressor (235) and a pressure tank (236) in the generator housing (211).
(FR) L'invention concerne une centrale houlomotrice flottante (100) qui comprend un arbre (102) pourvu de pales de rotor rotatives unidirectionnelles (101). L'arbre (102) est relié à un générateur (233) disposé à l'intérieur d'un bati de générateur (211) pour la production de courant électrique. Au moins deux moyens de flottabilité (106) sont reliés à l'arbre (102), et sont agencés pour commander le niveau de profondeur de la centrale houlomotrice (100) et l'angle d'inclinaison de l'arbre (102). Le moyen de flottabilité (106) est creux et présente un sac gonflable (133) fixé à l'intérieur du boîtier (111) et englobant l'arbre (102), ce qui définit un intérieur rempli de gaz (115) et un environnement rempli d'eau (114) à l'intérieur du boîtier (111). L'intérieur rempli de gaz (115) est vidé et rempli de gaz par l'intermédiaire d'un conduit (118), d'une vanne (117) et d'un conduit (116) et au moyen d'un compresseur (235) et d'un réservoir de pression (236) dans le bati de générateur (211).
