Description

Technical Field

[0001] The invention relates to the technical field of aerodynamic airfoils of wind turbine generator sets, and in particular to a main and auxiliary double-wing space lift blade propeller for a vertical axis wind turbine generator set. Background Art

[0002] A wind turbine is a mechanical device that converts the kinetic energy of wind into electrical energy. Therefore, one of the primary research objects of wind energy conversion is the blade. The aerodynamic performance of the blade determines its wind-catching ability and the wind energy utilization efficiency of the wind turbine. The mechanical performance of the blade controls the safety performance and economic benefits of the wind turbine.

[0003] The existing patent (publication number: CN212867764U) proposes a lift blade for a vertical axis wind turbine generator set, including a blade body, wherein the blade body is composed of an airfoil leading edge, an airfoil trailing edge, a C-shaped unidirectional curved flange, an S-shaped bidirectional curved flange, an internal space truss structure, a connecting point and a variable angle pitch adjustment system, and the relative thickness of the airfoil is D / C=0.183.

[0004] This invention uses the blade's flange curved surface with special aerodynamic characteristics to combine the blade with the variable angle pitch adjustment system in the low wind speed area, thereby increasing the wind rotor rotation torque value, solving the low wind speed starting problem and maintaining slow acceleration movement. It not only enables the wind turbine to start generating electricity under lower wind speed conditions, but also improves the wind energy utilization and power generation efficiency of the low wind speed wind turbine.

[0005] However, in actual use, the following deficiencies still exist, for example: existing single-wing wind turbines usually require a certain wind speed to start, which means that they cannot work under low wind speed conditions, thereby limiting their efficiency in low wind speed areas; the blades of single-wing wind turbines experience different wind speeds and angles of attack during rotation, resulting in their aerodynamic performance not being optimized, especially when the blades are close to the wind turbine tower, a wind shadow effect is formed due to the influence of the tower, reducing the efficiency of the blades; therefore, the present invention proposes a main and auxiliary double-wing space lift blade propeller for a vertical-axis wind turbine to solve the above problems.
