1. A water transportation pipe power generation device comprising:
a tubular power generator housing, wherein two ends of the housing are configured to dock with a respective pipe;
a stator component fixedly mounted inside the housing;
a tubular rotor component coaxially disposed inside the stator component, the rotor component comprising multiple rotor blades and permanent magnet groups,
wherein the stator component comprises;
a plurality of fixed coil windings which are uniformly distributed about an outer circumferential surface of the rotor component, and
an adjustable coil winding configured to be axially adjusted relative to the rotor component to change a magnetic flux,
wherein the rotor component further comprises a tubular rotor housing for a water flow to run through the rotor component,
wherein the multiple rotor blades are disposed on an inner circumferential surface of the rotor housing,
wherein the permanent magnet groups are disposed on an outer circumferential surface of the rotor housing, and
wherein the rotor component is configured to coaxially rotate relative to the stator component under a push action by said water flow to the rotor blades to generate power with the stator component.
