Abstract
The invention relates to a blade lay-up split-level structure, in particular to a wind driven generator blade skin lay-up split-level structure. The blade lay-up split-level structure is characterized in that the center line of a beam cap serves as an axis, and split-level layers are arranged by deviating from the axis upwards and downwards with a certain distance. Interlacing bamboo-shoot-shaped tapering is formed, rigidity of the position close to the root is enhanced, alternatively, the number of layers is reduced on the premise of the same rigidity, and cost is reduced.
Description
Technical field
The present invention relates to a kind of blade laying staggered floor construction, especially a kind of blade of wind-driven generator covering laying staggered floor construction.
Background technique
Traditional wind blade covering laying adopts symmetric type split level style.Being specially every layer of laying, to take the center line of beam cap rearmounted layer by layer as symmetry axis, and wedge angle is parallel to each other.
This mode is because paving mode is complicated, the certain distance that staggers between layers, and this is with regard to the problem such as cause cloth size to be difficult for grasping, waste material is many.And by laying depth, increase the mechanical property of root of blade, and virtually also increasing leaf weight, machine operating cost is increased.
In CN201739094U, relating to a kind of laying structure is gradient staggered floor, a several layers of mistake, every layer of glass-fiber-fabric that is monoblock.Although it has solved the problems such as waste of material laying process complexity, in increase blade mechanical property and minimizing leaf weight, also there is defect.
Summary of the invention
The technical problem to be solved in the present invention is: by designing a kind of staggered floor arrangement mode, overcome and when existing laying is arranged complex process, also solved the predicament that the increase of rigidity and the minimizing of quality can not realize simultaneously.
The technical solution used in the present invention is: the symmetrical laying by conventional art changes staggered floor dislocation laying into.Be specially, the beam cap center line of still just take is axle, lays all with the certain distance of an off-axis or fixed range each staggered floor of arranging up and down for every layer.
Beneficial effect of the present invention is: form alternating expression " bamboo shoot shape " and receive point, increase nearly root rigidity or reduce the number of plies under the prerequisite of equal rigidity, reduced cost.
Accompanying drawing explanation
Fig. 1 is traditional covering staggered floor arrangement mode
Fig. 2 is staggered floor arrangement mode of the present invention
Embodiment
In seeing figures.1.and.2, the present invention is different from traditional symmetry arrangement mode, and the value that each staggered floor departs from beam cap center line is δ, and, along beam cap center line+δ, the form of-δ is arranged, and by that analogy, has laid all gradient coverings.
Claims (2)
1. a blade laying staggered floor construction, has some staggered floors, it is characterized in that take that beam cap center line is axle, upper and lower off-axis certain distance each staggered floor of arranging.
2. blade laying staggered floor construction as claimed in claim 1, is characterized in that with the fixed range of upper and lower off-axis each staggered floor of arranging.
