Embodiment 2
The present embodiment optimizes design on the basis of embodiment 1, specifically：
Lightening hole 401 is located at the middle part of rib 40, because the cross sectional shape of blade is aerofoil shape, so in rib
Portion position is corresponding with the position that wing sectional dimension up and down is maximum, because wing middle part is usually the first girder 11, the
The Support Position of two girders 12, the rib of the position bears that support force is smaller, so designing lightening hole at the middle part of rib 40
401, can to greatest extent reduce the influence to rib structure performance.It is further preferred that when lightening hole 401 is arranged at the wing
During the middle part of rib 40, its girder of distance first, the distance of the second girder answer equal or approximate, and lightening hole 401 preferably makes
With round-shaped or elliptical shape, when using elliptical shape, oval short-axis direction is identical with the direction of web 20
Or overlap.
Embodiment 3
The present embodiment optimizes design on the basis of embodiment 1, specifically：
Lightening hole 401 includes two, is distributed on the rib 40 of the link position both sides of web 20.
In the present embodiment, a lightening hole 401 is separately designed in two side positions of web 20, so that the rib of web both sides
40 weight all reduces.
It is further preferred that lightening hole 401 should all be round-shaped, and the radius of circle is not limited, two losss of weight
The radius in hole can be with equal, it is also possible to；Understanding based on those skilled in the art, according to blade shell stress size, with
And the size of rib 40 designs the position of opening of lightening hole and selects suitable radius.
Rib 40 is general to be made by composite, and used as a kind of example, rib 40 is manufactured by sandwich material, and sandwich material will
Seek light weight and disclosure satisfy that the support strength that rib 40 is used.
The end face of web 20 is provided with the C-channel 201 for caving inward, the weight for mitigating structure.
Rib 40 is provided with the U-shaped groove 402 for being adapted to the first girder 11 and being connected with the link position of the first girder 11；
Rib 40 is provided with the U-shaped groove 402 for being adapted to the first girder 12 and being connected with the link position of the second girder 12.
U-shaped groove 402 is just connected with the first girder 11 or the adaptation of the second girder 12.
Using the structure design of U-shaped groove 402, the company between the girder 11 of rib 40 and first, the second girder 12 can be made
Connect more stable.
Reinforcement 404 is provided between wing rib structure 40 and blade shell 30, by reinforcement 404 by wing rib structure
40 provide stabilization support, prevent the unbalance stress of wing rib structure 40 and incline.
Reinforcement 404 selectively can be provided between the girder 11 of wing rib structure 40 and first, the second girder 12, by
In the first girder 11, the second girder 12 Stability Analysis of Structures itself, so reinforcement 404 is arranged on into the first girder 11, the second girder
On 12, the support effect of reinforcement 404 can be made more preferable.
Reinforcement 404 is a kind of measure for increasing the local Out-of Plane Stiffness of wing rib structure 40, and rib plate can be significantly greatly increased
The Out-of Plane Stiffness of structure 40, strengthens the support to wing rib structure, the ability of its resistance unstability is improved, in certain load range
It is interior so that local train is preferably controlled with stress.
Can selectively, the end face of web 20 is connected with rib 40 and web 20 is vertical with rib 40, by web 20
Rib 40 is connected, and then support is provided to rib 40, prevent rib 40 from being inclined to the side of web 20, so as to ensure that rib 40 has
There is more preferable support strength.
Preferably, the wind generator set blade that the present embodiment is provided is sectional-type blade.But based on people in the art
Understanding of the member to technical solutions of the utility model, the wind generator set blade that the present embodiment is provided can be used for monoblock type leaf
Piece.
