HYDROELECTRIC GENERATING APPARATUS

摘要

A water stream power generation system comprise a generator (3) driven by water streams to generate electric power, a floating body (5) floating on a water surface; a support structure (7) which is mounted to the floating body (5) such that the support structure is movable up and down and supports the generator (3), an up-down device (9) which moves up and down the support structure (7) to move the generator (3) between a position in water and a position above the floating body; and an anchor member (11) for anchoring the floating body to a fixed object.
