Magnetic levitation vertical axis wind power generation

Abstract

The invention discloses a zero friction wind turbine. The advanced magnetic levitation train technology is adopted to substitute a ball bearing, but a magnetic levitation force is still low. The magnetic levitation vertical axis wind power generation comprises that an acting force is produced by homopolar mutual repulsion in a magnetic field, and the produced magnetic levitation force is high, thus a windmill is suspended in the air and the friction resistance is reduced. The magnetic fields of a movable magnetic levitation magnet (4) and a fixed magnetic levitation magnet (5) are homopolar and repulsive, and the movable magnetic levitation magnet and the fixed magnetic levitation magnet stand face to face, a vertical axis windmill (2) comprises windmill blades (1) which are provided with movable magnetic levitation magnets (4) and is connected with a windmill vertical axis (3) provided with the fixed magnetic levitation magnet (4), wind power pushes the windmill blade (1), the movable magnetic levitation magnets (4) and a generator (7) provided with a speed changing driving device (6) to rotate, and a magnetic levitation vertical axis windmill can be conveniently pushed to generate electricity almost at zero frictional resistance, thus the aim of magnetic levitation wind power generation of a large-scale windmill is achieved. The center of gravity is low, and the zero friction wind turbine is convenient to construct and mount. The zero friction wind turbine disclosed by the invention has the advantages that the wind energy utilization factor is high and the wind power cost is reduced.

Description

(1) Technical field [0001] The invention relates to a magnetic levitation vertical axis wind power generation which can suspend the windmill in the air and reduce the frictional resistance through the force generated by the magnetic field isotropic mutual repulsion. (two), background technology [0002] With the shortage of global conventional energy and the aggravation of environmental pollution, seeking to use pollution-free renewable energy has become the general trend of global energy development. The world is paying more and more attention to the development of alternative energy sources. At present, the power generation power of global renewable energy is less than 1% of the world's power generation. Among various alternative energy sources, wind energy is the most mature, and its power generation cost is constantly decreasing. Wind energy is an abundant and clean natural energy, and the effective use of this renewable energy is of great significance. Wind turbines a...

Problems solved by technology

The disadvantage is: the friction resistance is large, and it is difficult to restart when the wind is insufficient, and it needs to be started by applying external force, so the vertical axis windmill is rarely used.

However, because the magnetic levitation force of this frictionless wind turbine is only within the effective vertical gravity line range of the small bearing, the magnetic levitation force is limited. Ineffective, such as my country's largest 3 megawatt windmill with a diameter of 100 meters and a weight of 120 tons has greater frictional resistance

It is obvious that the magnetic levitation force requires a certain area as a force support, that is to say, the horizontal axis windmill structure limits the application of large wind turbines
