| titleOfInvention | Bidirectional through-flow turbine |
| abstract | The utility model discloses a bidirectional through-flow turbine, which comprises a water inlet flow passage, wherein one end of the water inlet flow passage is tightly attached to the water inlet flow passage and is sequentially communicated with a guide vane section, a runner chamber, a tail water pipe diffusion section and a tail water pipe extension section; a hub body is also distributed along the direction of the central shaft of the water inlet flow passage, and the other end of the hub body extends to the tail water pipe diffusion section; the hub body is fixed in the water inlet flow channel through the buttress, the outer surface of the hub body is also respectively fixed with a circle of guide vanes and a circle of runner blades capable of rotating along the outer surface of the hub body, the tail ends of the guide vanes are close to the inner wall of the guide vane section, and the tail ends of the runner blades are close to the inner wall of the runner chamber; and a drainage blade is also fixed on the inner wall of the extension section of the draft tube. Through setting up the drainage blade at draft tube extension section, change the flow direction of rivers under the reverse operating mode, make rivers can clockwise rotation when getting into the runner, improved the circulation volume of rivers, simultaneously, also reduce the impact force of rivers to the runner, reduce the noise and the vibration of the hydraulic turbine, improved runner blade's fatigue life. |
