Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is further described: as figure 2 , 5 As shown, the lift-type elliptical spherical vacuum magnetic levitation wind turbine includes blades 13, fan main shaft 5, magnetic levitation bearing 23, transmission shaft 18, and an elliptical sphere 1 whose major axis is perpendicular to the ground. As an optimization scheme, the sphere The ratio of the major axis to the minor axis is 0.618.

[0030] Such as figure 1 , the spheroid 1 is provided with a through spheroid vertical axis circular hole 4 with its long axis as the central axis, and the hole wall of the spheroid vertical axis circular hole 4 on the inside of the spheroid 1 is provided with a spheroid inner tank 3. The sphere casing 2 on the outer surface of the sphere 1 is equipped with a week of the blades 13; the fan main shaft 5 runs through the vertical axis hole 4 of the sphere, as figure 2 , a pair of axial magnetic suspension bearings 23 a...

Abstract

A lift-type ellipsoid vacuum magnetic suspension wind turbine comprises blades, a fan spindle, magnetic suspension bearings and a transmission shaft, and further comprises an ellipsoid perpendicular to the ground. Taking the long axis as a central axis, the ellipsoid is provided with a through sphere vertical axis circular aperture; the fan spindle penetrates through the through sphere vertical axis circular aperture, the pair of axial magnetic suspension bearings is arranged in the middle of the through sphere vertical axis circular aperture, the outer side of a rotor pushing disc for the magnetic suspension bearings is fixed with the middle part of a sphere lining, and the inner side of the rotor pushing disc is fixed with the fan spindle; and stators at the upper ends and the lower ends of the magnetic suspension bearings are respectively provided with cylindrical magnetic suspension bearing stator radial protective devices. The lift-type ellipsoid vacuum magnetic suspension wind turbine has very stable aeroelasticity, and is light in overall mechanism, low in starting coefficient, higher in wind power utilization coefficient, wider in application range and lower in cost.

Description

technical field [0001] The invention relates to a wind power machine of a wind power device, in particular to a lift type elliptical ball vacuum magnetic levitation wind machine. Background technique [0002] There are many current wind turbines, such as horizontal axis wind turbines, vertical axis wind turbines; resistance wind turbines, lift wind turbines; shapes are also different, multi-wing type, propeller type, Sabinius type, Darrieus type Wait. But these wind turbines all have their big defects respectively, and the performance is not very stable, the function is single, the efficiency is low, and the wind energy utilization coefficient is generally 0.2-0.4. In particular, horizontal-axis wind turbines with relatively mature technology and a large number of popularized applications must be treated with special anti-flutter and anti-divergence due to their structural characteristics, which increases the cost and reduces the wind energy utilization factor. [0003] Th...
