Abstract
The invention discloses a vertical axis wind turbine blade frame structure. The vertical axis wind turbine blade frame structure comprises weft direction wing-shaped hoops, inclined struts between the inner sides and the outer sides of the hoops, ribs and inclined ribs; the ribs and the inclined ribs are arranged between all the layers of hoops; the weft direction wing-shaped hoops placed in parallel in layers and the ribs are arranged in an alignment manner in the radial direction; the two ends of each inclined strut are fixedly connected to the weft direction wing-shaped hoops so that the frame shape can be kept; the ribs and the inclined ribs are arranged around the weft direction wing-shaped hoops according to stress magnitude; connection points of the ribs and the hoops intersect with connection points of the inclined struts and the hoops; and the components are connected in a welded manner. The vertical axis wind turbine blade frame structure has the beneficial effects that the frame structure is easy to machine, a frame is stable, and borne wind loads are large.
Description
Technical field
The invention belongs to generator blade technical field, be specifically related to vane of vertical shaft wind-driven generator frame structure.
Background technique
In order to better utilize wind energy, for a long time, people devise the wind generator device of various structures form, according to the difference of wind driven generator rotation axle in direction in space position, are divided into the horizontal axis wind-driven generator of substantially horizontal and the vertical axis aerogenerator of Vertical direction.
Blade is the key member of wind-driven generator, and the cost of blades of large-scale wind driven generator accounts for about 25% of overall cost.Blade is main stand under load component, and mainly bear wind load, gravity load, centripetal force load etc., its working state does high speed rotating around wind turbine main shaft.In blade structure, general vertical axis aerogenerator all just continues to use the blade structure of Horizontal shaft aero-generator wind wheel.But the vane stress feature of the blade of vertical axis wind turbine and Horizontal shaft aero-generator wind wheel and boundary conditions all have notable difference, because blade is in rotary course, along with the increase resistance of rotating speed sharply reduces, and lift can increase on the contrary, so the efficiency of the vertical axis aerogenerator of lift-type wants the height of specific resistance type a lot.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of vane of vertical shaft wind-driven generator frame structure, has structure and easily process, frame stability, bear the feature that wind load is large.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
A kind of vane of vertical shaft wind-driven generator frame structure, comprise broadwise aerofoil profile hoop, hoop in outside between diagonal brace and each layer hoop between rib and diagonal rib, it is characterized in that: broadwise aerofoil profile hoop and the rib of the parallel placement of each layer align arrangement in radial direction, the two ends of diagonal brace are fixed on broadwise aerofoil profile hoop to keep the shape of framework, around broadwise aerofoil profile hoop, distribution is by stressed large riblet and diagonal rib, the tie point of the tie point of rib and broadwise aerofoil profile hoop and diagonal brace and broadwise aerofoil profile hoop crosses, by being welded to connect between each component.
Further, broadwise aerofoil profile hoop, diagonal brace, rib are all box-type sections.
Further, broadwise aerofoil profile hoop, diagonal brace, rib, diagonal rib are all aluminium profile.
Compared with prior art, the present invention has following beneficial effect:
Project organization of the present invention is easily processed, and the member section of each part is consistent, frame stability, bears wind load large, and material source is extensive, and be made into this locality, generating efficiency is high.
