Aerodynamic force suspension double-wing type connector and turbine rotor of vertical axis wind turbine

Abstract

The invention provides an aerodynamic force suspension double-wing type connector and a turbine rotor of a vertical axis wind turbine. The aerodynamic force suspension double-wing type connector comprises a first wing plate, a second wing plate, a first connecting plate, a second connecting plate, a third connecting plate, a fourth connecting plate and a supporting connecting rib, the first wing plate is located above the second wing plate and arranged opposite to the second wing plate, and the supporting connecting rib is connected between the first wing plate and the second wing plate; the first connecting plate and the second connecting plate are fixed to the inner edge and the outer edge of the first wing plate correspondingly, and the third connecting plate and the fourth connecting plate are fixed to the inner edge and the outer edge of the second wing plate correspondingly; the first wing plate and the second wing plate are provided with streamline structures for providing aerodynamic force buoyancy; and when airflow flows through, upward lift force can be generated, suspension of the turbine rotor is achieved, the mechanical friction loss of a bearing is reduced or even eliminated, and the wind energy conversion coefficient is increased. The turbine rotor comprises a central supporting column, a movable blade assembly and a plurality of double-wing type connectors, and also has the above advantages.

Description

technical field [0001] The invention relates to the technical field of new energy sources, in particular to an aerodynamically suspended double-airfoil connector and a vertical axis wind power generator turbine rotor. Background technique [0002] With global warming, reducing CO 2 The emission of carbon dioxide has become a concern of the whole world. The development of renewable energy is a new topic that has attracted much attention in the world. In particular, the utilization 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] At present, the development of wind power generators in low wind speed areas has become a hot spot in the wind power industry. On the o...
