Abstract[English]
The present invention relates to an underwater pumping device and method capable of moving over the seabed and of converting wave energy into high-pressure seawater pumping action for reverse osmosis desalination. The invention makes it possible to transform wave motion into linear motion by means of surface floats and an underwater float oscillating with the waves. The floats drive pistons that draw in, filter, and compress seawater. The movable pumping device is capable of positioning itself in synchronisation with the period and celerity of the waves by sliding by means of an anchoring system rolling on a conveying pipeline that carries the pumped water directly to a reverse osmosis station. The pipeline is anchored to the seabed by means of a series of deadman anchors. The sliding mechanism makes it possible to retrieve and remove the pumping device from the water for weather-risk prevention and for cleaning and maintenance.[French]
La présente invention concerne un dispositif et un procédé de pompage sous-marin ayant la capacité de se déplacer sur le fond marin capable de convertir l'énergie de la mer en action de pompage à haute pression d'eau de mer pour le dessalement par osmose inverse. L'invention permet de transformer les mouvements des vagues en un mouvement linéaire au moyen de flotteurs de surface et de flotteur sous-marin oscillant avec les vagues. Les flotteurs actionnent des pistons qui aspirent, filtrent et compriment l'eau de mer. Le dispositif de pompage mobile est capable de se positionner en synchronisation avec la période et la célérité des vagues en coulissant au moyen d'un système d'ancrage roulant sur un pipeline de renflouement de l'eau pompée directement vers une station d'osmoseur inverse. Le pipeline est ancré au fond marin au moyen d'une série de corps morts. Le dispositif de coulissement permet de rapatrier et de faire sortir le dispositif de l'eau pour une action de prévention des risques météorologiques ainsi que pour le nettoyage et la maintenance.
