Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the wind power blade of the utility model comprises a girder 1 containing a beam edge core material 2 and a shell cloth layer,

this wind-powered electricity generation blade has special manufacturing process, and it is at first with roof beam limit core 2 and girder 1 integrated into one piece in advance, when treating the casing and spread the layer, will contain roof beam limit core 2's girder 1 and casing cloth layer fully combine, and concrete step is as follows:

(1) manufacturing a girder 1

(2) And manufacturing a transition material block, wherein the transition material block is an original material which is not cut.

(3) And cutting the transitional material block into a specific shape and size by using cloth cutting scissors or other cutting tools according to the width requirement of the girder 1 and the thickness design requirement of the transitional core material to form the beam edge core material 2.

(4) And completing glass fiber cloth winding and laying of the beam edge core material 2 and the girder 1, and integrally pouring and forming to form the girder 1 with the beam edge core material 2.

(5) The method comprises the following steps of finishing the laying of the glass fiber cloth corresponding to the outer shell in the assembling equipment, hoisting the prefabricated girder 1 with the beam edge core material 2 into the outer shell, and then continuously finishing the laying of the rest glass fiber cloth layer.

(6) And after the layer laying of the shell is poured, curing and molding the shell by using high temperature.

(7) And (3) assembling and bonding the PS surface shell and the SS surface shell, bonding the web 5 on the girder 1, and curing to finish the blade manufacture.

Wherein, the transitional core material formed in the step (2) can be triangular, circular arc or trapezoidal.

And (3) the prefabrication and forming process of the beam edge core material 2 and the girder 1 is that after the girder 1 is formed, the bonding material is used for independently bonding, curing and forming.

The bonding material adopts glue.

The blade structure comprises shells, adhesives, a crossbeam 1 with a beam edge core material 2 and a web 5, wherein the two shells are fixedly adhered by the adhesives 4, each shell is formed by adhering the crossbeam 1 with the beam edge core material 2 and a blade core material 3, the crossbeam 1 with the beam edge core material 2 is formed by winding a glass fiber cloth on the crossbeam 1 and pouring resin glue on the beam edge core material 2 and then air-drying the poured resin glue, the beam edge core materials 2 are arranged on two sides of the crossbeam 1, and the blade core materials 3 are arranged on two sides of the beam edge core material 2;

the beam structure further comprises two web plates 5, and two ends of each web plate 5 are respectively adhered to the two girders 1.

The utility model has the advantages that:
