AI Technical Summary
Traditional turbine blade structures make it difficult to dynamically adjust the inlet flow rate and angle, leading to decreased efficiency and problems such as wear, corrosion, and vibration. Existing regulating devices are complex and costly.
It adopts a rotatable blade swing head and hinge connection, with the blade tail end overlapping design. It uses stainless steel or alloy materials and combines a hydraulic drive system to achieve dynamic adjustment and wear resistance, reducing flow loss.
It improves the efficiency of water turbines under non-design conditions, reduces maintenance costs and failure rates, extends equipment life, and enhances operational reliability and economic benefits.
