Abstract
A wind-driven power generation device based on magnetic levitation is provided. The device includes a magnetic levitation structure, a wind fan, a driving fan, and an electric power generator. Since a floating magnet floated above a fixed magnet in the magnetic levitation structure, the rotation friction of the fan shaft of the wind fan can be greatly reduced to stabilize the output electric power of the wind-driven power generation device.
Claims15
A wind-driven power generating device based on magnetic levitation, the device comprising:
- a magnetic levitation structure, comprising:
- a magnet holder;
- a fixed magnet fixed on the magnet holder;
- and
- a floating magnet disposed above the fixed magnet, wherein same magnetic pole of the fixed magnet and the floating magnet are opposite to each other so that the floating magnet floats above the fixed magnet;
- a wind fan comprising a fan shaft and a plurality of blades fixed on the fan shaft, wherein a lower end of the fan shaft is rotatably coupled to the floating magnet;
- a driving fan comprising a power supply for providing electric power thereto for driving the driving fan, wherein the driving fan is disposed on a side of the wind fan, so that the blades of the wind fan are driven when the driving fan generates wind;
- and
- an electric power generator comprising a mandrel, wherein the mandrel is connected to an upper end of the fan shaft of the wind fan, so that the mandrel is driven by rotating the wind fan and thus the electric power generator generates electric power.
