Abstract

The embodiment of the invention relates to the technical field of wind power generation, and provides a suspension bearing for a vertical-axis wind power generation device. The suspension bearing forthe vertical-axis wind power generation device comprises a transmission shaft system, a rotor, a stator, at least one magnetic suspension unit, and at least one aerodynamic suspension unit, wherein acentral supporting column connected with the transmission shaft system is arranged above the transmission shaft system. The stator is located outside the rotor, and the rotor is connected with the transmission shaft system and the central supporting column and can rotate along with the central supporting column. The magnetic suspension units can drive the rotor to suspend relative to the stator under the action of electromagnetic attraction force. The aerodynamic suspension units are connected with the rotor and the central supporting column and can generate lifting force for promoting the rotor to suspend relative to the stator. According to the suspension bearing for the vertical-axis wind power generation device, electromagnetic force of the magnetic suspension units and aerodynamic force of the aerodynamic suspension units are combined, huge buoyancy is generated, and the acting range of a draught fan relative to wind speed changes is enlarged.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a suspension bearing for a vertical axis wind power generation device. Background technique [0002] With global warming, reducing CO 2 The amount of emissions has become a concern of the whole world, and the development of renewable energy is a new topic that has attracted much attention around the world. In particular, the use of wind energy has opened up a green channel to reduce carbon dioxide emissions. Wind energy has huge reserves and is widely distributed. It can be picked up locally without transportation and is easy to use. The use of wind energy has developed from the initial wind power to lift water, wind power to aid navigation, etc. to today's wind power generation. [0003] Since the wind resources in the south of the Middle East are much lower than those in the "Three Norths" region, the wind resources in the south of the Middle East can reach 900...
