Abstract
The utility model relates to a wind turbine blade, which belongs to the field of components of wind power generation equipment. The existing large-scale wind turbine blade has the defects of relatively complex manufacture, relatively higher cost and the like. The utility model comprises a blade root and a blade body which are connected into a whole, wherein the blade body mainly comprises a skeleton and a pneumatic shell covered on the skeleton, and the skeleton comprises stringers and ribs which are connected into a whole by casting; and the ribs are covered outside the stringers, and the ribs are riveted with the stringers by rivets. The utility model reduces the weight of the blade, increases stiffness and yield strength, and reduces cost and manufacturing difficulties.
Description
Technical field
The utility model belongs to the wind power plant part field, and is especially relevant with a kind of wind-powered electricity generation machine blade.
Background technique
For improving the strength and stiffness of blade, prevent local buckling, large-scale blade mostly adopts the girder skeleton to add the structural type of pneumatic shell, the main forms such as balladeur train D type commonly used, O type, rectangle or Two bors d's oeuveres channel-section steel of dying, pneumatic housing is the moulding covering, girder adopts the girder steel welding, and covering develops into glass fibre reinforced plastics or composite material forming from using cloth to make.Girder steel glass fibre covering blade covering and girder steel bonding area are little, and solidification intensity is low and come off easily, cause operation process dangerous high; The leaf weight that composite material is made is heavier, poorly conductive causes anti-lightning strike performance poor, development for the super sized type blade of wind-driven generator still is restricted, and the carbon-fibre reinforced epoxy resin blade involves great expense, materials such as glass fibre reinforced plastics epoxy resin, carbon fiber mainly refine from oil, pollute in manufacture process greatly, raw material sources can be exhausted, is again non-renewable.
The model utility content
The purpose of this utility model is exactly to overcome the above-mentioned defective that existing large-scale wind electricity machine blade exists, and a kind of rigidity and yield strength height, relative simple, relatively low wind-powered electricity generation machine blade and the manufacture method thereof of cost of manufacturing are provided.For this reason, the utility model is by the following technical solutions:
A kind of wind-powered electricity generation machine blade, comprise the blade root and the blade body that connect as one, blade body mainly is made up of skeleton and the pneumatic housing that is covered on the skeleton, and it is characterized in that: described skeleton comprises longeron and the rib that casting is connected as a single entity, and rib is wrapped in the longeron outside.
Described pneumatic housing is spliced by at least 2 coverings.
Adopt riveted joint between described pneumatic housing and the described skeleton.
Blade root of the present utility model and blade body skeleton adopt the cast aluminium alloy casting, and during riveted joint lid dress pneumatic housing, pneumatic housing can be a writing board shape, uses rivet after the extruding pneumatic housing makes it with skeleton outer rim warpage.
Use the utility model can reach following beneficial effect: the longeron of skeleton and rib use the cast aluminium alloy casting to be connected as a single entity, and have alleviated leaf weight, have improved rigidity and yield strength, have reduced cost; Use the riveted joint of plate shaped pneumatic housing and skeleton, reduced manufacture difficulty.
Description of drawings
Fig. 1 is blade root and a skeleton structural drawing partly in the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, wind-powered electricity generation machine blade described in the utility model comprises blade root 1 and the blade body that connects as one, blade body mainly is made up of skeleton and the pneumatic housing that is covered on the skeleton, and skeleton comprises longeron 3 and the rib 2 that casting is connected as a single entity, and rib 2 is wrapped in longeron 3 outsides.Pneumatic housing is spliced by 2 flat aluminium alloy plate material coverings, adopts riveted joint between pneumatic housing and the skeleton.
Blade root of the present utility model and blade body skeleton adopt the cast aluminium alloy casting, and during riveted joint lid dress pneumatic housing, pneumatic housing is a writing board shape, uses rivet after the extruding pneumatic housing makes it with skeleton outer rim warpage.
Claims (3)
