Description

TECHNICAL FIELD

[0002] A generator is a device for converting mechanical energy into electrical energy. It uses external forces (such as water power, wind power, thermal power, etc.) to drive the rotor inside the generator to rotate, and then generates an electric current in the stator through electromagnetic induction principle, so as to realize energy conversion and supply. A water current generator is a device for converting the kinetic energy of water flow into mechanical energy and driving a generator to generate electricity.

[0003] For example, Chinese patent CN215719195U discloses a micro water power generator with side-in and downward-out, which comprises a shell. A micro alternating current generator is installed in the shell. The micro alternating current generator is composed of a coil framework and a magnetic steel. A ceramic shaft sleeve is installed at the bottom of the coil framework. A coil end cover is installed in the shell. A first water inlet is formed on one side of the shell. A water outlet lower cover is installed at the bottom of the shell. A second water inlet and a water outlet are formed on the surface of the water outlet lower cover. Water flows from the first water inlet into the second water inlet and then flows out of the water outlet, thereby driving the micro alternating current generator impeller to rotate and generate electricity.

[0004] The impeller of the micro water power generator is installed in the water outlet lower cover. The flow direction of the water flow driving the impeller to generate electricity adopts the side-in and downward-out mode, that is, the water flows from the first water inlet into the second water inlet and then flows out of the water outlet. The area of the water inlet is relatively small, and the matching degree with the impeller is low, resulting in poor power generation efficiency, which needs to be improved. SUMMARY
