ABSTRACT:
The device exploits the energy of waves (32) of an open water body (30). It comprises at least one fixed float (34), at least one extendable pumping element (10) and one pressure medium (24). The pumping element (10) attached to float (34) has at least one gas- and/or fluid-impermeable hose (12) which expands radially while shortening in the longitudinal direction and which has one inlet and/or outlet opening for at least one hydraulic and/or pneumatic pressure medium (24). On each hose (12) lie flexible longitudinal fibers (14) of high tensile strength, which run preferably parallel when extended. The fibers (14) have an upper force attachment (16) connected to the float (34) and a lower force attachment (18) connected to a fixing (38). The tensile force (Z) is applied in the longitudinal direction of the pumping element (10) and never to a hose.
Ideally the fibers (14) are arranged in guide rings (20) at regular intervals.
The device is used for example as an energy source for an electric power station, water supply, water storage, mixing and aeration of standing water and the desalination of sea water.
