Abstract

This invention relates to the field of power generation technology, specifically to a hydrodynamic power generation device for fixed river equipment, comprising: a power management and communication control component; a navigation buoy, wherein the power management and communication control component is fixedly connected to the upper end of the navigation buoy; two mounting plates, both fixedly connected to the side walls of the navigation buoy; a connecting pipe, which is fixedly connected through the side walls of the two mounting plates; a three-section waterproof generator, wherein the lower end of the connecting pipe is fixedly connected through the interior of the three-section waterproof generator; and multiple disc-type coreless permanent magnet synchronous generators. In this invention, the axial flow impeller adopts a lightweight aluminum alloy material and a low-inertia fan blade design, combined with an array layout of multiple small-power disc-type coreless permanent magnet synchronous generators, reducing the overall starting torque of the system. Simultaneously, the disc-type coreless permanent magnet synchronous generators employ a printed coil stator and a radially magnetized permanent magnet rotor, effectively reducing cogging torque and eddy current losses.
