Abstract

A wind driven generator, including a wind turbine unit and a generating device, is disclosed. The wind turbine unit is driven by the wind and a shaft of the wind turbine unit rotates the rotor in the generating device. Thus, the rotor circles the stator with a coil to generate current and supply power.

Claims

1. A wind driven generator, comprising:

a wind turbine unit comprising a vane module and a shaft, and the vane module is rotated by natural wind to rotate the shaft; and

a generating device mounted on the shaft of the wind turbine unit and comprising a rotor connected to the shaft and a stator disposed around the rotor;

whereby the wind turbine unit is driven by natural wind to rotate the rotor of the generating device through the shaft relative to the stator to generate electricity.

2. The wind driven generator of claim 1, further comprising an electricity-storage unit electrically connected with the generating device to store the electricity generated by the generating device.

3. The wind driven generator of claim 2, wherein the generating device is connected with the electricity-storage unit via a wire to store the electricity generated by the generating device in the electricity-storage unit.

4. The wind driven generator of claim 1, wherein the generating device further comprises at least one bearing connected to the shaft and a shell embracing the stator and the rotor.

5. The wind driven generator of claim 4, wherein each of the at least one bearing comprises an outer circle mounted on the shell tightly.

6. The wind driven generator of claim 4, wherein each of the at least one bearing comprises an inner circle mounted on the shaft tightly.

7. The wind driven generator of claim 1, further comprising a mounting unit on which the wind turbine unit is mounted.

8. The wind driven generator of claim 1, wherein the wind turbine unit further comprises a base, and the vane module comprises a plurality of vanes;

wherein the shaft is mounted in the base and the vanes are mounted around the shaft and connected to the base.

9. A wind driven generator, comprising:

a plurality of wind turbine units wherein each of the wind turbine units comprises a vane module rotated by natural wind and a shaft rotated by the vane module;

a plurality of generating devices connected respectively to the wind turbine units, each of the generating devices comprising a rotor mounted on the shaft and a stator disposed around the rotor; and

at least one electricity-storage unit electrically connected with the generating device;

whereby the wind turbine units are driven by natural wind to rotate respectively the rotors of the generating devices to generate electricity stored in the at least one electricity-storage unit.

10. The wind driven generator of claim 9, wherein the generating device is connected with each of the at least one electricity-storage unit by a wire to store the electricity generated by the generating device.

11. The wind driven generator of claim 9, wherein each generating device further comprises at least one bearing and a shell, and the at least one bearing is mounted between the shaft and the shell, and the shell embraces the stator and the rotor.

12. The wind driven generator of claim 11, each of the at least one bearing comprises an outer circle mounted on the shell tightly.
