Area-variable V-shaped perpendicular-spindle wind turbine blade structure

Abstract

The invention provides an area-variable V-shaped perpendicular-spindle wind turbine blade structure and relates to the improvement of a wind turbine structure, in particular to a perpendicular-spindlewind turbine blade structure. The area-variable V-shaped perpendicular-spindle wind turbine blade structure is characterized in that a plurality of frame body fixing brackets are parallel to one another, divided into upper and lower layers, and connected onto a perpendicular spindle in a sleeving manner; a plurality of groups of blade mechanisms are directly arranged on the upper and lower framebody fixing brackets; a transmission gear is fixedly arranged on a spindle of a motor and meshed with the inner ring of the corresponding frame body fixing bracket; the engine body of the motor is fixedly arranged on a base; and the perpendicular spindle is perpendicularly and fixedly arranged on the base. According to the beneficial effects, the area-variable V-shaped perpendicular-spindle wind turbine blade structure has the advantage of being low in production, transportation and manufacturing cost; the wind conversion efficiency is high; and the area-variable V-shaped perpendicular-spindlewind turbine blade structure is applicable to various application sites.

Description

technical field [0001] The invention relates to an improvement of a wind power generator structure, in particular to a blade mechanism of a vertical axis wind power generator. Background technique [0002] With the development of the wind power industry, the requirements for blades are getting higher and higher. For blades, stiffness is also a very important indicator. Studies have shown that the stiffness of carbon fiber (carbon fiber, CF) composite blades is two to three times that of FRP composite blades. Although the performance of carbon fiber composites is much better than that of glass fiber composites, it is expensive, which affects its wide application in wind power generation. Therefore, the world's major composite material companies are conducting in-depth research on raw materials, process technology, quality control and other aspects in order to reduce costs. The design of blades in wind turbines directly affects the conversion efficiency of wind energy and i...
