Cambered-surface tapered type guide flip bucket used in spiral flow shaft volute chamber
The invention provides a cambered-surface tapered type guide flip bucket used in a spiral flow shaft volute chamber. The guide flip bucket is arranged at one side of a junction of volute chamber inlet water flow of a spiral flow shaft and water flow which rotates by one circle, consists of a right-triangle-shaped vertical surface which extends and humps along a volute chamber wall surface and a guide cambered surface which is crossed with an inclined side of the right-triangle-shaped vertical surface from an upper flat section bottom plate and the above volute chamber wall surface, so that a triangular cone which is big in upper part and small in lower part, and provided with a cambered surface is formed; a crossed part of the guide cambered surface beginning part and the volute chamber wall surface is a smooth curved surface. The cambered-surface tapered type guide flip bucket can keep water flow to rotate downwards in the volute chamber by a way of adhering to the wall while preventing forming reflux by water flow impact in an inlet of the volute chamber.
