AI Technical Summary
Existing tidal current turbines have insufficient starting torque at low flow rates, are prone to stall and cavitation at high flow rates, have poor adaptability to complex reciprocating flows, have high operation and maintenance costs, are easily damaged, and lack self-protection mechanisms.
The biomimetic whale fin variable pitch tidal power turbine is designed, which adopts biomimetic blades and wave-shaped nodal structure, combined with independent variable pitch drive and fairing, to achieve vortex-induced flow direction, adaptive pitch control and anti-entanglement protection, and uses servo motors and controllers to achieve self-protection under multiple operating conditions.
It improves the low-flow-rate start-up capability, enhances the hydrodynamic efficiency at high flow rates, reduces operation and maintenance costs, improves the survivability and power generation efficiency of the device, and reduces mechanical vibration and noise.
