Water transportation pipe power generation device with flow-regulating and pressure-regulating function

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.
