Title:
COMBINED IMPULSE WATER TURBINE RUNNER
Document Type and Number:
WIPO Patent Application WO/2023/087683
Kind Code:
A1
Abstract:
Disclosed is a combined impulse water turbine runner, relating to the technical field of impulse water turbines. The combined impulse water turbine runner comprises water buckets, a wheel disc, an upper cover plate and a lower cover plate; multiple water buckets are provided and uniformly arranged on a periphery of the wheel disc, a water bucket comprising a bucket root at an inner end and a bucket at an outer end; the bucket root has an embedded shifting fork structure, and comprises an upper shifting fork and a lower shifting fork, the upper shifting fork and the lower shifting fork being provided with multiple upper and lower coaxial bucket root holes, and an embedded block being located between the upper shifting fork and the lower shifting fork at an end close to the bucket; a first shaft hole is formed in the center of the wheel disc, multiple hole systems are formed on the surface of the wheel disc, multiple wheel disc through holes are formed in each hole system along a circumferential direction, and multiple embedded grooves are uniformly distributed along a circumferential edge of the wheel disc; the embedded blocks are embedded into the embedded grooves, so that the embedded blocks and the wheel disc bear partial tangential force of jet flow-impacted bucket roots; a second shaft hole is formed in the center of both the upper cover plate and the lower cover plate, and the plate surfaces are provided with multiple cover plate fixing holes.
