Device for generating hydroelectric energy

Abstract

The invention relates to a device for generating hydroelectric energy, using the swell of a mass of water, said device containing an impeller which is rotatable around a shaft and at least one electric generator group, the drive shaft of which is coupled at least in one direction of rotation in a torque transmitting manner to the impeller shaft, whereby the device is provided with a floating casing which contains two compartments which are partly filled with fluid and which via a passage are fluidly connected with each other, whereby the device furthermore contains an air-filled caisson, which has an open bottom and opens out to said passage and whereby in said caisson the impeller is rotatably mounted around a shaft which extends perpendicular to the direction of the passage and whereby the impeller is partly mounted in the air-filled space of the caisson and partly in the fluid in the passage.
