Water wheel, hydraulic power generation device, and hydraulic power generation system

Abstract

A water wheel includes a casing to carry a fluid flow through an inside of the casing, a pipe extending in the inside of the casing, a rotor unit having a shaft to be inserted in the inside of the casing, and a support. The shaft is directed toward the pipe. The rotor unit is detachably attached to the casing from outside. The support supports the rotor unit at a predetermined position relative to the pipe when the rotor unit is attached to the casing. A hydraulic power generation device includes the water wheel and a generator driven by the water wheel. A hydraulic power generation system includes the hydraulic power generation device and a flow path with the hydraulic power generation employed in the flow path.
