HYDROELECTRIC POWER GENERATION DEVICE

摘要

This hydroelectric power generation device is equipped with: an upstream conduit (1) and a downstream conduit (2) installed in a water passage; a runner casing (3) sandwiched between the upstream conduit and the downstream conduit; bosses (4a, 4b, 4c) arranged along the axial direction of the runner casing; and a runner (5) housed within the runner casing so as to be capable of rotating around the axial center of the runner casing. The bosses are divided into two stationary boss units (4a, 4c), which are affixed respectively to the upstream conduit and the downstream conduit along the axial direction of the runner casing, and a rotating boss unit (4b), which is fitted into the runner. An armature (70) is arranged in one of the stationary bosses (4c), a water conduit (40) passes through this stationary boss in the axial direction, and a permanent magnetic field (80) is installed in the rotating boss.
