Title: Water turbine power generation apparatus automatically adjusting draft utilizing water flow guidance and automatic adjustment to enhance power generation efficiency
Inventor: LIN SHUEEI MUH
IPC: F03B7/00
Filed: 2021-10-25
Abstract: To provide a water turbine power generation apparatus in which, as compared with conventional water turbine power generation apparatuses, there are more vanes receiving effective water flow impact, timing to receive the impact is early, thrust of a runner is increased, and power generation efficiency can be enhanced.SOLUTION: A water turbine power generation apparatus includes a water turbine power generation unit and a floatation water flow guidance unit. The floatation water flow guidance unit is connected to the water turbine power generation unit and is for guiding a water flow to the water turbine power generation unit. Specifically, the flotation water flow guidance unit divides the water flow into an upwelling flow and a sinking flow, in which the height of the water surface of the upwelling flow is higher than the water surface of the sinking flow. As compared with conventional water turbine power generation apparatuses, the upwelling flow collides with vanes located above the water surface, so that pressure is more quickly applied to the vanes and the power generation efficiency is improved. Since the height of the sinking flow is lower than that of normal water, the vanes enter the water with a more vertical inclination, and it is possible to prevent the vanes from hitting the water surface over large areas and to extend the service life. In addition, in the water turbine generation apparatus according to the present invention, draft can be adjusted by a suspension adjustment unit.SELECTED DRAWING: Figure 1A
