Background technology
At present, global energy crisis is progressively aggravating, and the utilization of regenerative resource has received extensive concern, such as sun
It has developed rapidly in terms of energy, wind energy, tide energy, many wind power stations, establish in succession.In the field of wind-power electricity generation, vertical axis
Wind-driven generator is at low cost due to having many advantages, such as, easy to maintain, and vertical axis wind electric unit just gradually develops to the fast gesture that maximizes.
And in vertical axis wind power generation field, the staring torque of fan blade is reduced, the assembling facilitation problem of generating equipment blade is big
The key subject of power shaft wind-power electricity generation blade.And existing vertical axis wind power generation wind blade is big to the resistance of wind, wind-force
Staring torque it is big, it is impossible to keep the continuity of electrical power generators, powerful vertical axis wind power generation blade volume is big, transport
Assembling is inconvenient.
Utility model content
The utility model is big to the resistance of wind for the existing vertical axis wind power generation wind blade of solution, the startup power of wind-force
Square is big, it is impossible to keep the continuity of electrical power generators, powerful vertical axis wind power generation blade volume is big, and transport assembling is not square
Just the problem of, and then propose a kind of vertical shaft wind-driven generator spiral built up blade.
The utility model adopts the technical scheme that in order to solve the above problem：The utility model includes at least one blade master
Body, upper cover and lower cover, the top and bottom of blade main body are connected respectively with upper cover and lower cover.
Further, upper cover and lower cover are made of disk and three circular arc vanes, three circular arc vanes edge circles
Circumferential direction is uniformly arranged at the edge of disk, and edge of the blade root of each circular arc vane with disk links into an integrated entity.
Further, the lower surface of disk is equipped with tongue, and the lower surface of each circular arc vane is equipped with groove.
Further, it is provided with through hole in the middle part of disk.
Further, blade main body is the spiral blade being vertically arranged.
Further, the height of blade main body is 1m~2m.
Further, the ratio between the maximum width of the height of blade main body and blade main body is 5:Within 3.
Further, the upper surface of blade main body is parallel with lower face.
The beneficial effects of the utility model are：1st, the utility model can greatly reduce fan blade by using fabricated structure
Staring torque, ensure power generation continuity；2nd, the utility model uses triad structure, reduces the body of vertical axis blade
Product, transport easy to carry occupy little space, expand use scope；3rd, the blade main body of the utility model is distributed in generator
The all directions of main shaft, manage-style is not blown from which direction can promote blade, rotate generator shaft, since blade is made
Spiral shape considerably increases the area of blade windward, therefore has the condition for reducing blade area.
