Abstract
The utility model relates to a wind wheel structure of a vertical axis wind driven generator, wherein a wind wheel is phi-shaped and mainly consists of more than two blades that are evenly distributed; each blade is formed in a way that above three blade units are connected; a connecting flange is arranged at the connecting end of each blade unit; and screw holes are arranged on each connecting flange. The blades exist in forms of the blade units in the production and transportation process; the blade units are assembled after being transported to a wind field; as long as the connecting flanges at the connecting ends of the adjacent blade units are locked by screws, the assembly of the blades is completed, and the split structures of the blades facilitate the transportation.
Description
Technical field
The utility model relates to vertical axis aerogenerator, especially the blade structure of wind wheel.
Background technique
Wind energy is a kind of green energy resource, and adopting wind power generating set is to be the suitable method of electric energy with wind energy transformation.Calculate by cost of electricity-generating, the cost of the big more every degree electricity of the design power of separate unit wind-driven generator is low more often.Yet blower fan is big more; Can make the excessive overlength of blade of wind-driven generator; And the individual blade of blower fan often adopts overall structure not split; Thereby the freight that makes blade transport to wind field from the workshop is risen sharply, even is difficult to realize the transportation of blade, and this has just restricted the more development of high-power wind-driven generator.
Summary of the invention
The utility model technical problem to be solved provides a kind of vertical axis aerogenerator wind wheel structure, can split blade, convenient transportation.
For solving the problems of the technologies described above, the technological scheme of the utility model is: a kind of vertical axis aerogenerator wind wheel structure, and said wind wheel is Φ shape, and said wind wheel mainly is made up of equally distributed blade more than two; Said blade is formed by connecting the above blade unit of three joints, and the connecting end of every joint blade unit is provided with adpting flange, and said adpting flange is provided with screw.Blade all is to exist with blade unit from produce transportation process; Assemble again after transporting blade unit to wind field, only need the adpting flange of adjacent vanes unit connecting end can be accomplished the assembling of blade, the convenient transportation of the fractionation structure of blade through screw lock.
As improvement, said blade unit comprises the body that skeleton is outer with being wrapped in said skeleton.
As improvement, the cross section of said blade unit is water droplet shape small in ends broad in the middle, and a wherein end wherein small in ends is a nose circle, and the other end is most advanced and sophisticated.
As improvement, the shape of said adpting flange is similar with the sectional shape of said blade unit.
As improvement, the body of said blade unit is a high strength fibre spare.
The beneficial effect that the utility model is compared with prior art brought is:
Blade all is to exist with blade unit from produce transportation process; Assemble again after transporting blade unit to wind field, only need the adpting flange of adjacent vanes unit connecting end can be accomplished the assembling of blade, the convenient transportation of the fractionation structure of blade through screw lock.
