Abstract
A water transportation pipe power generation device with flow-regulating and pressure-regulating function is provided comprising a tubular power generator housing, a stator component fixedly inside and a tubular rotor component coaxially disposed inside the stator component. The stator component comprises fixed coil windings uniformly distributed on an outer circumferential surface of the rotor component and an adjustable coil winding capable of performing axial movement along the rotor component and adjusting an axial position to change a magnetic flux. The rotor component comprises a tubular rotor housing for a water flow to run through. Multiple spirally-distributed rotor blades are disposed on an inner circumferential surface of the rotor housing, and permanent magnet groups in sensing cooperation with the fixed coil windings and the adjustable coil winding are disposed on an outer circumferential surface of the rotor housing. The rotor component can coaxially rotate for power generation relative to the stator component.
