<p>A hydraulic generating apparatus comprises a water tank (1), a float (3), a linear-rotation conversion mechanism (4), and a generator (5). Water can be supplied into and discharged from the water tank (1). The float (3) is arranged to float in the water tank (1), and it moves up and down in accordance with a fluctuation in water surface level. The linear-rotation conversion mechanism (4) comprises a male screw shaft (41) and a female screw body (42). The male screw shaft (41) is rotatably supported, the female screw body (42) is screwed together with the male screw shaft (41) and interlocks with linear movement when the float (3) moves up and down, and the male screw shaft (41) is rotated by a linear displacement at the time of this interlocking. The generator (5) is driven by the rotation of the male screw shaft (41).</p> |
