Problems solved by technology

[0003] In the prior art, the wind energy utilization rate of the vertical-axis lift fan can be as high as 42% during normal operation, but this type of vertical-axis lift fan mainly has the following defects: small starting torque, complex structure, high cost, and high speed of the wind rotor. lower
However, the stability and balance of the vertical flexible wind wheel of the vertical axis flexible wind wheel also need to be further improved, and resonance is easy to occur and is relatively serious in a wide speed range under the action of various wind forces and wind directions, which also needs to be improved. However, the flexible suspension cable is easy to knot and break, making its service life low, and it is difficult to use in strong winds.

Abstract

The invention discloses a multilayer-wing-blade vertical-axis wind turbine generator system. At least two layers of wind wheels are sequentially mounted on a rack mechanism from bottom to top. The rack mechanism is in transmission connection with vertical axes of generators. In a vertical projection direction view, a plurality of fan blade units are circumferentially and evenly distributed. Each fan blade unit comprises a support rod, an articulated mechanism and a fan blade. An articulated base is arranged at one end of each support rod. The articulated bases are rotationally connected with the rack mechanism through first pins. The fan blades are hinged to the other ends of the support rods through the articulated mechanisms. Cushions are arranged between the rack mechanism and the support rods. The multilayer-wing-blade vertical-axis wind turbine generator system is provided with at least two layers of fan wheels, wind pressure is continuous and uniform, and the torque of the wind wheels are transmitted to the generators through racks, so that wind energy utilization rate and generating capacity are high; at least two layers of fan wheels are mounted on the multilayer-wing-blade vertical-axis wind turbine generator system and can work synchronously and coordinately, so that smoothness in operation is kept while the windward area of fan wheel sets is increased, and cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of vertical-axis wind power generators, in particular to a multi-layer wing swing blade type vertical-axis wind power generator capable of stable rotation. Background technique [0002] At present, there are two main types of vertical-axis wind turbines: one is the lift-type wind turbine that uses the lift of the airfoil structure to do work, and its prototype is the Darrieus wind turbine. The manufacturing technology of most vertical-axis wind turbines is On the basis of the operation principle of the airfoil structure, a little improvement technology is carried out; the other type is the resistance type fan, whose prototype is evolved from the wind cup type anemometer, and its principle is to use the front and back of the wind blade when it rotates horizontally. The difference in the resistance of the two sides to the wind does work. [0003] In the prior art, the wind energy utilization rate of the verti...
