MARINE POWER GENERATING SYSTEM AND MARINE POWER GENERATING METHOD

摘要

[Problem] To provide a marine power generation system which is engineered to be able carry out power generation stably and highly efficiently, using the large source of energy even in ocean currents having insufficient speeds to create a water current, similar to a water discharge from a dam, which is ideal for hydroelectricity.;[Solution] As an example of a water intake structure (10), a sea surface floatation object, floats on the sea by buoyancy, and has an aperture part (12) through which seawater is taken therein. A water guide pipe (20) is underwater, which secures a space underwater. One end of the water guide pipe (20) is connected to the sea surface floatation object (10), and the seawater which is taken in from the sea surface floatation object which is the water intake structure (10), is introduced downward under the sea surface. Power generators (30) that generate power from either the falling motion of the seawater or water pressure are in the water guide pipe (20), and carry out power generation. A submersible body (40) is in the water, and an accumulation space (41) is provided that takes in the seawater which is discharged from another end of the water guide pipe (20). The seawater that is taken into the accumulation space (41) in the submersible body (40) is discharged outward from the submersible body (40) by a discharge part (50).

1. A marine power generation system comprising;
a water intake structure for taking in seawater, wherein the water intake structure comprises an aperture part for taking in seawater, and an upper seawater guide part for sending the taken-in seawater from the aperture port to an inner portion; a seawater drop pipe comprising an upper terminal and a lower terminal for supplying a dropping space undersea for dropping the taken-in seawater from the upper terminal which is connected with the upper seawater guide part to the lower terminal; a power generator installed in the water drop pipe for generating electricity power by motion of the dropping seawater and/or by a water pressure of the taken-in seawater; a submersible body connecting with the lower terminal of the seawater drop pipe for supplying a seawater tank space for temporarily storing the discharged seawater from the lower terminal of the seawater drop pipe; a forced discharge part for discharging the stored seawater from the seawater tank space of the submersible body to the outer undersea forcibly.
