Stage structure, marine power generation apparatus and marine structure having the stage structure

摘要

PROBLEM TO BE SOLVED: To provide a construction measure capable of converting spontaneous kinetic energy such as waves or wave motions in the ocean into electric energy by a certain measure on the hypothesis that the spontaneous kinetic energy is used as a small ocean water power dam and eliminating waves and wave motions to construct an emergency port of shelter or a submarine resources developing ocean base. SOLUTION: High waves or wave motions in the ocean are sea-surface layer phenomena, and an ocean wave phenomenon does not occur in a deep layer. When an oscillational and fluid water depth area of the greatest depth of the water influenced by waves (the extent of a draft of a super-tanker) is cut, the wave phenomenon can be prevented. When a submarine coming to the surface is anchored and is washed by high waves, since such a phenomenon as waves get over the submarine is frequently seen, when an inclined platform shaped stage jump is constructed to the front end of a barge, waves and wave motions suddenly raise the stage, and a channel descending from the barge at a steep slope is provided to make waves and wave motions as a fast-stream, it descends the channel, a bearing is provided to a side wall to use it as a rotational bearing of a hydraulic turbine, the hydraulic turbine is rotated to make torque as an accelerator or rotational driving force of a generator inside of the barge to generate electricity.
