  • Turbine hydroelectric power generation device, and power generation method based on pressurized water inlet pipelines
    Patent number: 12680525
    Abstract: According to a turbine hydroelectric power generation device and a power generation method based on pressurized water inlet pipelines, after water flows are input into liquid inlet flow channels and guided by guide vanes, by arranging the liquid inlet flow channels that are the vortex-shaped spiral flow channels, it can be ensured that the water flows are evenly diverted by the guide vanes and thus are output to a driving rotor at the same flow velocity to impact and drive the driving rotor to rotate. The driving rotor can drive, during rotation, a power generation rotor to rotate inside a magnetic power generation mechanism to generate electricity, and the input water flows are finally collected by a bottom liquid discharge mechanism and then separated into multiple water flows to be output respectively.
