Abstract
The invention relates to blades of a wind driven generator. A main structural material of the blades is strip bamboo and strip glass fiber reinforced plastic pultrusion sections, and the strip bamboo is connected with the strip glass fiber reinforced plastic pultrusion sections by adopting a special beveling mode.
Description
Technical field
The present invention relates to a kind of strip bamboo composite material and the connecting means of strip glass fibre reinforced plastics drawing and extruding section bar, the bamboo composite material that is particularly useful in the blade of wind-driven generator manufacturing is connected with strip section.
Background technique
Blade is the critical component of the effective capturing wind energy of wind power generating set.Under the condition that generator power is determined, how to improve generating efficiency, to obtain bigger wind energy, it is the target that wind-power electricity generation is pursued always, and catch the raising of wind energy power and shape, length and the area of blade has confidential relation, the size of blade dimensions then mainly depends on the material of making blade.The material of blade is light more, strength and stiffness are high more, and the ability that blade is resisted load is just strong more, and blade just can be done greatly more, and its wind energy power of catching is also just strong more.Therefore, the composite material of high-strength light, good endurance becomes the preferred material of present large-scale wind generating blade.
Wind power generation blade just under arms mostly is composite material blade at present.These blades be basically by thermoset substrate resin and E-glass fibres such as polyester resin, vinylite and epoxy resin, (glass fibre is a kind of Inorganic Non-metallic Materials of excellent performance to the S-glass fibre, mainly be divided into 5 types according to its composition, E-glass fibre and S-glass fibre are wherein two kinds), reinforcing material such as carbon fiber, be composited by moulding process such as manual lay or resin injections, to satisfy the usage requirement of different wind fields.
Bamboo wood is a kind of natural environmental-protective section bar material, by the bamboo wood that laminating technology makes, can satisfy the mechanical property requirements of blade main structure material, can effectively reduce the blade cost again, also is convenient to the recycling of material.
But bamboo wood is different with glass fibre reinforced plastic material, on the one hand bamboo wood is not thermosets (thermosets refer to be subjected to high temperature action after hardening and irreversible macromolecular material), can not earlier glass fibre be laid in body surface as glass fibre reinforced plastics, add the resin solidification moulding again, existing on the other hand bamboo wood all is a strip section, and length has certain restriction, every length is approximately 2m～3m, need find a kind of special connecting means when therefore making blade of wind-driven generator with bamboo wood, bamboo wood and glass fibre reinforced plastics drawing and extruding section bar can be linked together, can satisfy the requirement of intensity aspect again.
Summary of the invention
The present invention is intended to address the above problem, for this reason, the objective of the invention is to propose a kind of method that connects bamboo wood and glass fibre reinforced plastics drawing and extruding section bar, the requirement of strength that the connection that utilizes this method to make can be satisfied blade of wind-driven generator makes processing method become simply easy-to-operat again.
According to the present invention, a kind of bamboo wood and glass fibre reinforced plastics drawing and extruding section bar or the connecting means of carbon fiber drawing and extruding section bar are proposed, (laminating technology is meant the sheet material that is soaked with or scribbles resin stacked the strip bamboo composite material that comprises the steps: a) to adopt laminating technology to make given shape, under the heating pressurized conditions, a kind of moulding process of solidifying, comparatively common at glass fibre reinforced plastics and ground board industry) b) (pultrusion molding process is a kind of technology comparatively common in the glass fibre reinforced plastics manufacturing to adopt pultrusion molding process to make the strip glass fibre reinforced plastics drawing and extruding section bar of given shape or carbon fiber drawing and extruding section bar, the object with certain geometrical shape that adopts this technology to make is called glass fibre reinforced plastics drawing and extruding section bar or carbon fiber drawing and extruding section bar, and wherein strip is its Common Shape) c) with strip bamboo composite material, strip glass fibre reinforced plastics drawing and extruding section bar or carbon fiber drawing and extruding section bar are the main structure material; D) bamboo wood and drawing and extruding section bar wherein an end be processed into angle of chamfer or angle of chamfer is processed at two ends, the ratio of cutting sth. askew was greater than 1: 5; E) section bars such as bamboo wood and glass fibre reinforced plastics drawing and extruding section bar are pieced together on blade mold the mode of scarf with scarf put together again; F) by the vacuum introducing technology resin is injected positions such as gap between the scarf at last, be solidified into blade shell or web.Use the strip bamboo wood and the section bar of pre-processed shape in the blade production scene, can make easy to operate, quick, do not produce waste material and rubbish, but the common employing of strip material link overlaps (two kinds of materials of the same type overlap and connect) or docks the mode of (being meant enemy's combination of two articles end), join strength is not enough concerning blade of wind-driven generator, and the Placement of this mitered of the present invention has solved not enough this key issue of join strength between strip bamboo wood and the drawing and extruding section bar.
Description of drawings
By hereinafter with reference to the description part that accompanying drawing carried out, can better understand all above-mentioned features, described accompanying drawing is:
Fig. 1 is the sectional view in described blade of wind-driven generator cross section;
Fig. 2 is the whole process flow of connection profile;
Fig. 3 is the strip section of an end angle of chamfer;
Fig. 4 is the strip section of two ends angle of chamfer;
Fig. 5 is the angle of chamfer ratio;
Fig. 6 has the strip section of two ends angle of chamfer to combine for two shown in Figure 3;
Fig. 7 is the compound mode of A place main structure material in the housing shown in Figure 1.
Embodiment
Connection provided by the invention, be mainly used in the housing parts of blade of wind-driven generator, form by materials such as bamboo wood section bar and glass fibre reinforced plastics drawing and extruding section bars, referring to accompanying drawing, Figure 1 shows that the sectional view of blade of wind-driven generator, comprise housing 1 and web 2, housing mainly is made up of main structure materials such as bamboo wood and glass fibre reinforced plastics.
Figure 2 shows that the whole process flow of connection profile, comprise the steps:
S1: material is prepared, the raw material that are used for connecting, adopt bamboo wood section bar and glass fiber reinforced plastic shapes or carbon fiber section bar etc., common laminating technology is made strip in the existing furniture floor making of the bamboo wood section bar employing industry, common pultrude process is made strip in glass fiber reinforced plastic shapes or the existing glass fibre reinforced plastics industry of carbon fiber section bar employing, every profile length does not wait from 2m～3m, part section bar has only an end face to be sawn into " ∠ " word shape, two end faces of another part section bar all are sawn into " ∠ " word shape, the requirement inclined-plane is smooth, and scarf is thick long than being not more than 1: 5.
S2: the saw inclined-plane Figure 3 shows that the section bar that an end is cut sth. askew, the scarf of mark 3 for sawing out among the figure.Figure 4 shows that the two ends section bar of cutting sth. askew, the scarf that mark 4 is sawed out for the section bar two ends among the figure.Figure 5 shows that the angle of chamfer of scarf.
