摘要:
Plant for exploiting wave power, particularly for the production of electrical energy, provided with a float (16) which moves, guided laterally, in a large-diameter guide tube (1,1') with its lower end immersed in the sea and the other end facing upwards, fixed to any suitable support means and provided laterally with at least one window (7) positioned at sea level, in which said float is normally located and through which the wave enters to raise and lower the same float. Said float is axially integral with a movable duct (14) which extends downwards to draw water from the sea through suction valve means (15) and which crosses said float to allow entry into the same of a fixed pumping duct (11) which, via discharge valve means (12), is connected at the top to a fixed pipe (9) positioned on the upper end of said guide tube (1,1') for delivery of the water pumped by said system of fixed and movable ducts (11,14) operated by the float (16) and provided with said valve means (12,15). Said fixed pipe (9) and/or said fixed duct (11) will be sustained by a supporting structure (3,10) positioned in the upper surfaced part of said guide tube (1,1') so that by easily acting on said supporting structure (3,10), the pump-float assembly can be removed for maintenance and the inside of said guide tube (1,1') can be accessed for all maintenance and/or cleaning requirements.
摘要:
Plant for producing electric power from the movement of waves, characterized in that it comprises an offshore dam (17) for separating a section (20) of sea inside it, such as a port zone, from an open-sea section (22) and comprising towards this open-sea section (22) a submerged part which has, formed therein, one or more ducts (14, 15) and/or inlets (28) for receiving the water, provided upstream and/or downstream with non-return valve means (8, 10, 29); at least one turbine (16) connected to electric power generating means is positioned in this offshore dam (17) or in a land zone also at a distance from this offshore dam; this turbine (16) is connected upstream to at least one water supply duct (1 1, 25, 30) in turn connected upstream to suitable pumping means (6) or thrust means (31, 32) able to convey the water received via these ducts (14, 15) and/or inlets (28) towards this duct (1 1, 25, 30) for supplying water to this turbine (16).
