Fan blades on vertical axis wind power generation equipment

Abstract

The invention discloses fan blades on vertical axis wind power generation equipment. Each fan blade comprises a supporting frame, a transmission shaft fixed to the supporting frame, a fan blade supporting arm hinged to the transmission shaft and a fan blade fixed to the end of the fan blade supporting arm. Multiple fan blade supporting arms are arranged. The rotating centers of the fan blade supporting arms are connected in series through concentric rotary shafts. Multiple fan blades are uniformly distributed on the rotating circumference, and the adjacent to fan blades are staggered uniformlyin the vertical direction. The fan blades on the vertical axis wind power generation equipment reduce vertical planes of gaps among the fan blades, so that when air blows the blades, the starting difficulty of a fan is reduced and a power generator is smoothly started. Meanwhile, the stationarity of the power generator equipment in operation is also increased, and the full degree of a power generation power curve is increased.

Description

Technical field [0001] The invention relates to the field of power generation equipment, in particular to a wind blade on a vertical axis wind power generation equipment. Background technique [0002] Most of the existing vertical axis wind power generation equipment is a layer of blades. The blades are evenly distributed on the rotating circle. These blades form different angles with the wind direction. When the wind blows over the blades, a driving torque relative to the central axis will be generated. Drive the motor shaft to rotate, but this single-layer blade uniform distribution method cannot easily make the main shaft rotate, especially when the wind direction is perpendicular to the blades, or perpendicular to the vertical plane of the gap between the blades, this angle becomes Starting the dead corner increases the difficulty of starting. Summary of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a wind blade ...
