[0031] In the second embodiment of the present invention, magnetic protection ring 7 is made of galvanized plate, to raise the generator output power voltage under the same generator rotation speed. Cylinder-shape turret-type water slant holes are utilized, to ensure water output angle to be more accurate, so that water flow can be more concentrated to impact on the impeller 9. As such, even under low water flow pressure, the rotation speed of the generator can be increased, to raise the output power voltage of the generator. Further, secondary injection is utilized such that the magnet 12 is completely insulated from water through encapsulation, to prevent corrosion of the magnet 12, thus avoiding the generator magnet water corrosion problem caused by surface barrel plating treatment of the magnet 12. 3-dimensional (3D) turbine blade design is used, so the impeller 9 rotation speed can be raised, under the same water flow impact, hereby raising the output power voltage of a generator. The water slant holes are designed into turret type, to work in cooperation with the 3D turbine blade, so that the impeller 9 may obtain higher rotation speed, under lower water flow pressure. In addition, the magnetic protection ring 7 is able to protect the strength of the magnetic field, such that the generator can provide higher output power voltage even having the same rotation speed. In this approach, the problem that under low water flow pressure, generator output voltage can not meet the requirement of load, can be solved.

However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention. Conversely, its purpose is to include the various changes and equivalent arrangements which are within the scope of the appended claims.
