Description
Technical field
The present invention relates to a kind of outer cover that is used for wind-driven generator, more particularly say, be meant a kind of composite external cover with lightweight three-dimensional layer sandwich structure.
Background technique
Wind-driven generator is a kind of wind energy to be converted to mechanical energy, mechanical energy is converted to the energy conversion device of electric energy or heat energy etc. again.Through years of researches and development, diversified wind-driven generator has appearred.In recent years, the wind-power electricity generation cause is developed rapidly in the world as a kind of clean energy resource, caused numerous composite material enterprise, especially composite material for weaving enterprise showing great attention to and dropping into, this is that composite material for weaving obtains increasing promotion and application because make as blade in the main member of wind-driven generator and outer cover.
The outer cover of wind-driven generator is a kind of Large Shell Structure, includes the outer cover that engine room cover, air guide sleeve etc. form.
Summary of the invention
In order to alleviate the own wt of existing wind-driven generator outer cover, and the outer inconvenience that covers on dismounting and transportation in being applied to large-scale wind driven generator, the present invention designs a kind of wind electricity unit composite external cover with three-dimensional layer sandwich structure.The present invention adopts modular design concept to make this outer cover be made up of fair water cone and a plurality of ring cover body, and the structure of a plurality of ring cover bodies is identical, and a plurality of ring cover body is installed on the fair water cone after according to the cylindrical structure layout.Fair water cone and ring cover body have adopted fabric that textile technology produces as a shop layer materials, have reduced the own wt of outer cover effectively.
A kind of wind electricity unit composite external cover with three-dimensional layer sandwich structure of the present invention, this composite external cover includes fair water cone 1, air guide sleeve and engine room cover three parts; Air guide sleeve is to be made of according to the tapered cylinder topology layout is conformal six ring cover bodies, six ring cover bodies are meant A ring cover body 2, B ring cover body 3, C ring cover body 4, D ring cover body 5, E ring cover body 6 and F ring cover body 7, annulus 2a in the conformal formation of last connecting end of A ring cover body 2, B ring cover body 3, C ring cover body 4, D ring cover body 5, E ring cover body 6 and F ring cover body 7, annulus 2b under the conformal formation of following connecting end of A ring cover body 2, B ring cover body 3, C ring cover body 4, D ring cover body 5, E ring cover body 6 and F ring cover body 7; Engine room cover includes cabin A cover body 8, cabin B cover body 9 and cabin loam cake 10.
The cross section structure of fair water cone 1, air guide sleeve and engine room cover three parts outside in is surface layer, three-dimensional layer sandwich fabric layer and nexine in turn; The three-dimensional layer sandwich fabric layer is by upper layer of fabric, layer fabric, and the intermediate fabric composition that is used to connect upper layer of fabric and layer fabric.
The configuration configuration of the intermediate fabric in the three-dimensional layer sandwich layer that the cross section structure of the composite external cover of the present invention's design adopts is the figure of eight, " 1 " font, oblique " 1 " font, " W " font or " V " font.
A kind of wind electricity unit composite external cover with three-dimensional layer sandwich structure advantage of the present invention is:
(1) the composite external cover own wt is light, owing to adopted cooperating of three-dimensional hollow fabric that textile technology produces and resin, behind resin solidification, the hollow fabric of this three-dimensional just becomes the three-dimensional layer sandwich structure that has the space of hard.
(2) cross section structure of composite external cover (including fair water cone 1, air guide sleeve and engine room cover three parts) adopts the hierarchy design, and promptly surface layer, three-dimensional hollow fabric, nexine help different layers and realize different functions.Sun-proof, corrosion protection that surface layer plays, three-dimensional hollow fabric plays and alleviates outer cover weight, and nexine plays functions such as heat insulation.
(3) cross section structure of composite external cover (including fair water cone 1, air guide sleeve and engine room cover three parts) adopts shop layer-coating method evenly applying resin on surface layer, three-dimensional hollow fabric, the nexine, and be solidified into the formwork of hard at normal temperatures, its preparation process simple controllable, do not need large-scale accessory machinery, reduced the cost of production of producing outer cover.
(4) three-dimensional hollow fabric can not be laid at the connecting end of air guide sleeve, side, semicircle piece place, and replaces to chopped strand, helps improving the intensity of junction point.
(5), and use textile technology establishment, the working life of having improved outer cover because the material that composite external cover adopts is a glass fibre.
