Anti-magnetic levitation wind power energy collector

Abstract

The invention relates to an anti-magnetic levitation wind power energy collector comprising a housing, a permanent magnet arranged in the housing, an upper pyrolytic graphite plate, an upper stator, an upper permanent magnet rotor, a blade, a lower permanent magnet rotor, a lower stator and a lower pyrolytic graphite plate; the upper and lower permanent magnet rotors are respectively fixed on topand bottom ends of the blade so as to be connected to form an integral rotor assembly; a rotor assembly receives a magnetic force of the permanent magnet in the vertical direction and an anti-magneticforce of the lower pyrolytic graphite plate, and receives an anti-magnetic force of the upper pyrolytic graphite plate and the self gravity, wherein the sum of the magnetic force of the permanent magnet in the vertical direction and an anti-magnetic force of the lower pyrolytic graphite plate is equal to the sum of the anti-magnetic force of the upper pyrolytic graphite plate and the self gravity, thus allowing the rotor assembly to suspend between the upper and the lower pyrolytic graphite plates. The collector can greatly reduce the device frictions; in addition, the blade can greatly increase the wind receiving area between the upper permanent magnet rotor and the lower permanent magnet rotor, thus driving the upper permanent magnet rotor and the lower permanent magnet rotor to rotatetogether under a weak wind current, converting weak wind energy in the environment into electric energy, and greatly improving the wind utilization efficiency.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to an anti-magnetic levitation wind energy collector. Background technique [0002] The principle of wind power generation is to use wind power to drive the generator rotor to rotate to generate electric energy. Wind power generation is a pollution-free and renewable green power. Today, countries all over the world attach importance to energy conservation and environmental protection, and people pay more and more attention to wind power generation. At present, the commonly used wind power generators usually fix the generator on the upper end of the pole or tower through the connecting flange, and directly fix the rotating shaft of the wind blade on the top of the generator. Or it cannot generate electricity when there is a slight wind, and most generators have requirements on the wind direction. During the power generation process, the wind direction needs to be adjusted contin...

Problems solved by technology

At present, the commonly used wind power generators usually fix the generator on the upper end of the pole or tower through the connecting flange, and directly fix the rotating shaft of the wind blade on the top of the generator. Or it cannot generate electricity when there is a slight wind, and most generators have requirements for the wind direction. During the power generation process, the wind direction needs to be adjusted continuously, which makes the operation troublesome. When the fan is running, the friction between the parts is large, the energy consumption is high, and the conversion rate is low.

Now people apply the magnetic levitation technology to the support of the wind turbine rotor, and replace the traditional mechanical bearing with the magnetic levitation bearing. Although the friction between the rotor and the bearing is greatly reduced and the power generation efficiency is improved, the rotating part and the non-rotating The mechanical friction between parts still exists, and a certain amount of cut-in wind is also required, which is not suitable for promotion and use in areas with low wind speed all year round
