ABSTRACT:
A hydraulic power generating device includes a main body case forming a flow passage provided with a water wheel chamber between a fluid inlet port and a fluid outlet port, a cover covering the main body case, a water wheel for power generation disposed in the water wheel chamber, a rotor magnet for rotating in cooperation with the water wheel. An ejection port including a groove is formed on the main body case for ejecting fluid toward the blades of the water wheel at a high speed and an protrusion part is formed on the cover for adjusting the aperture area of the ejection port by entering into the groove. Further, a discharge space is formed at a downstream position of the water wheel chamber so as to be in communication with the fluid outlet port, to which fluid after having rotated the water wheel is ejected and a stagnation preventing protrusion part is formed in the discharge space to facilitate flow of air bubbles to the fluid outlet port.
