ENGINE OF THE SYSTEM OF SINKING AND SETTING A SHELTER IMPERMEABLE OF SEA WATER IN SEA, PROTRUDING A PLATE OPPOSED TO MOVEMENT OF WAVE FROM THE OUTER UPPER SURFACE OF THE SHELTER UPWARD IN WATER TO TAKE THE LOWER END OF THE PLATE AS FULCRUM, MOUNTING A PENDULUM SWUNG BY THE MOVEMENT OF THE PLATE WITHIN THE SHELTER UNDER THE FULCRUM, CHANGING THE ENERGY OF WAVES RECEIVED BY THE PLATE TO THE SWING OF THE PENDULUM, AND TAKING THE ENERGY FROM THE SWING OF THE PENDULUM

PROBLEM TO BE SOLVED: To effectively utilize the energy of waves. SOLUTION: A shelter 20 containing the essential part of an engine and an apparatus such as generator and preventing intrusion of sea water, which is set in the sea 2, has a wave receiving plate 5 into water on the outer upper part. The lower end of the wave receiving plate 5 is set as a fulcrum 6, and a pendulum swung by the movement of the wave receiving plate 5 is provided within the shelter 20 under the fulcrum 6, and hydraulic pumps 8, 8 are operated in the reciprocating direction of waves to efficiently absorb the energy of waves received by the wave receiving plate 5. The movement of each part of the wave receiving plate 5 is conformed to the difference in speed by the depth of the waves, and the period of the pendulum is regulated to conform to the period of the waves. The depth of the wave receiving plate 5 is raised and lowered to the sea level or sea bottom when the wave height is low or high, whereby a fixed quantity of wave energy can be absorbed.
