Abstract
The utility model discloses a main shaft vertical type wind wheel connecting structure which comprises main blades, upper connecting wings and lower connecting wings. The main shaft vertical type wind wheel connecting structure is characterized in that a die once forming structure is adopted in the main blades, the upper connecting wings and the connecting lower wings. The main shaft vertical type wind wheel connecting structure has the advantages of ensuring high-speed operation of a main shaft vertical type wind driven generator and connecting strength of the main blades, the upper connecting wings and the lower connecting wings, being stable in operation, reducing fatigue shaking of the upper connecting wings and the lower connecting wings, and prolonging service life of a wind wheel of the main shaft vertical type wind driven generator and a wind turbine.
Description
Technical field
The utility model relates to technical field of wind power generation, relates in particular to the rectilinear wind wheel linkage structure of a kind of main shaft.
Background technique
Wind-driven generator of the prior art comprises horizontal axial type and perpendicular axis type two classes, and in the rectilinear wind wheel of original main shaft, main lobe and connecting wing are with bolts, the drawback of existence be waste time and energy, requirement of strength is high and complex process.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides the rectilinear wind wheel linkage structure of a kind of main shaft.
The technical solution adopted in the utility model is:
