The present invention relates to a generator and, more particularly, to a wind power generating device.
A wind power generating device, such as a windmill, a wind turbine or the like, is driven by the wind power so as to produce an electric power. Thus, the wind power generating device uses the green energy to achieve an environmental protection purpose. However, the conventional wind power generating device has a complicated structure, thereby increasing the cost of fabrication and installation. In addition, the conventional wind power generating device has a larger volume and is not operated conveniently.
The primary objective of the present invention is to provide a load-free wind power generating device that is operated without needing any external load.
In accordance with the present invention, there is provided a wind power generating device comprising a stand, a shaft mounted on the stand, a rotor rotatably mounted on the shaft, a stator mounted on the stand and disposed in the rotor, and an impeller mounted on the rotor. The stator includes a plurality of magnetic coil columns. The stator has a central position provided with a hole. The rotor surrounds and covers the stator. The rotor has a central position provided with a bearing mounted on the shaft. The rotor has an inner periphery provided with a plurality of magnetic elements corresponding to the magnetic coil columns of the stator. The shaft extends through the hole of the stator and the bearing of the rotor. The bearing of the rotor is locked onto the shaft. The impeller is secured to the rotor.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The stator 10 includes a plurality of magnetic coil columns 100. Each of the magnetic coil columns 100 includes a plurality of magnetic coils. The stator 10 has a central position provided with a hole 101, and the shaft 11 passes through the hole 101 of the stator 10. In practice, the stator 10 is electrically connected with a storage battery 2 by electric wires 20. The rotor 12 surrounds and covers the stator 10 and is rotatable relative to the stator 10.
The rotor 12 has a central position provided with a bearing 120 mounted on the shaft 11. The rotor 12 has an inner periphery provided with a plurality of magnetic elements 121 corresponding to the magnetic coil columns 100 of the stator 10. Each of the magnetic elements 121 is a magnet. The shaft 11 extends through the hole 101 of the stator 10 and the bearing 120 of the rotor 12. The bearing 120 of the rotor 12 is locked onto the shaft 11. The impeller 13 is secured to the rotor 12 by screwing. The impeller 13 is mounted on one end of the shaft 11. Preferably, the impeller 13 is a helical fan.
In the preferred embodiment of the present invention, a distance between the magnetic coil columns 100 of the stator 10 and the magnetic elements 121 of the rotor 12 is at least 2 mm.
In operation, when the impeller 13 is driven and rotated by the wind power, the rotor 12 is driven by the impeller 13 and rotated relative to the stator 10, such that the magnetic elements 121 of the rotor 12 are displaced relative to the magnetic coil columns 100 of the stator 10, to produce a magnetic field which is converted by a magnetic conversion to produce an electric current which flows through the electric wires 20 into the storage battery 2. Thus, an electric power is generated through magnetic interaction between the magnetic elements 121 of the rotor 12 and the magnetic coil columns 100 of the stator 10, and is stored in the storage battery 2.

Accordingly, the wind power generating device converts the wind energy into an electric energy by a magnetic effect, without using any load, thereby decreasing the cost of production. In addition, the wind power generating device uses the green energy to generate the electric power, thereby preventing from causing an environment pollution. Further, the wind power generating device is operated constantly to generate the electric power all day long, without being limited the weather conditions, thereby enhancing the utility of the wind power generating device. Further, the distance between the magnetic coil columns 100 of the stator 10 and the magnetic elements 121 of the rotor 12 is equal to or more than 2 mm, to increase the rotation speed of the rotor 12, so as to derive the maximum electric power. Further, the impeller 13 is rotated at a smaller speed to rotate the rotor 12, such that the wind power generating device is still operated under a smaller wind power, to produce and supply steady and enough electric energy.
