Description

Technical Field

[0001] This utility model relates to the field of hydropower generation, and in particular to an impeller for hydropower generation. Background Technology

[0002] Hydropower generation uses water as power to drive an impeller, which in turn drives a generator to produce electricity. The impeller is a crucial component. Currently, waterwheel-type impellers still have certain problems in use. For example, during long-term use, the impeller blades are damaged by the impact of water flow, and the water flow carries many impurities, which can lead to blade damage and replacement. In traditional impeller manufacturing, the blades and the impeller disc are generally fixed by welding and bolts. Welding cannot be disassembled but has high stability, while bolt installation requires more bolts and has slightly lower stability, but it can be replaced. Both methods have certain limitations.
