Power generating installation

A power generating installation for generating power utilizing a shallow water wave,comprising:

• a mooring member;
• a force transmitting member having one end connected with said mooring member and another end to which a dead weight is attached;
• and
• a float provided with (i) a generator and (ii) a rotary member for rotating engaged with said force transmitting member;
• wherein said rotary member produces a rotary force when said float moves up and down according to an up-and-down motion of the wave, and said rotary force is transmitted to said generator to thereby cause said generator to generate power;
• wherein said rotary member and said generator are connected through a reversible unit having an input shaft and an output shaft which are arranged so that the output shaft rotates constantly in a single direction regardless of a direction of rotation of the input shaft, thereby causing the generator to also rotate in a single direction both when the wave is rising and when the wave is falling throughout the up-and-down motion of the wave;
• wherein said reversible unit includes a gear mechanism for transmitting a rotary force of said generator to said rotary member;
• and
• wherein at a time of a marine anomaly, said generator is made to function as an electric motor and rotates said rotary member through said gear mechanism to thereby bring down said float below a sea surface.
