Description
Technical field
The utility model relates to vertical axis aerogenerator, especially a kind of vertical axis aerogenerator blade link structure in working life that improves.
Background technique
The blade of vertical axis aerogenerator is connected by supporting wing with generator, and dual mode is arranged usually, and a kind of is that supporting wing 1 passes blade and blade 2 direct-connected modes, as shown in Figure 1; Another kind is to adopt hoop 3, will bind round 3 and be set in blade 2 outsides and fixing, and supporting wing 1 and hoop 3 ways of connecting, as shown in Figure 2.First kind of mode simple for structure but need blade material to have very high anti-shearing force characteristic, the complex structure of the second way, but less demanding to blade material, just to the material of hoop with have relatively high expectations, that is to say that the material that needs to make hoop has high anti-shearing force and also needs to have high bending resistance square, corrosion resistance and anti-aging characteristic.
Because of glass fibre reinforced plastics has good flex resistance, corrosion resistance and weatherability, therefore general relatively large fan blade is all made by glass fibre reinforced plastics, but anti-shearing force poor-performing because of glass fibre reinforced plastics, therefore the blade link structure of relatively large vertical axis aerogenerator all adopts the above-mentioned second way, just supporting wing and hoop ways of connecting.
Because blower fan need bear the requirement of working under harsh outdoor environment, the supporting wing that adopts existing metallic material to make at present, part cracking or the rust candle that is welded to connect at supporting wing and hoop often, thus influenced blower fan integral body working life and outward appearance, cause the accident even.The moving element of existing structure generally can only reach 5-10 working life.
The model utility content
For solving the problems of the technologies described above, a kind of vane of vertical shaft wind-driven generator link structure is now proposed, be to link into an integrated entity as matrix with sheet metal and fan-catcher, on described sheet metal, be provided with some through holes that wear winding for fiber; The composite material of the outside resin-coated and fiber of matrix.
On above-mentioned fan-catcher, be provided with some through holes that wear winding for fiber.Make the fiber that coats fan-catcher twine mutually, strengthen as the sheet metal of integrative-structure and the intensity of fan-catcher by the through hole of fan-catcher and the through hole on the sheet metal.
The through hole of offering in above-mentioned fan-catcher is installed with nut, is convenient to fixed blocks such as bolt blade and fan-catcher are fixed.
The shape of sheet metal is the wing shape, prolongs substantially horizontal at sheet metal stiffening rib is set, and improves the flex resistance of this sheet metal.
The through hole of offering on above-mentioned sheet metal is installed with nut, is convenient to fiber and wears winding, to improve intensity and rigidity.
Above-mentioned sheet metal and fan-catcher link into an integrated entity as matrix adopting be the welding.
Above-mentioned sheet metal and fan-catcher link into an integrated entity, and it connects angle is 45 degree～135 degree.
Above-mentioned sheet metal and fan-catcher link into an integrated entity, and preferably connecting angle is 90 degree.
The composite material of the outside resin-coated and fiber of above-mentioned matrix is a glass fibre reinforced plastics.
Further, for weight that alleviates supporting wing and the anti-bending strength that improves supporting wing, the glass fibre reinforced plastics that adopts is the double glazing steel with certain aerodynamic configuration, and the supporting wing cross section curve is combined by three groups of ellipse curves and satisfies spline curve, and intermediate portion thickness is big, two limit thickness-tapereds.Keep when alleviating supporting wing weight supporting wing the bending resistance square ability and have less resistance of air.
Be connected by metal construction between above-mentioned sheet metal and vertical axis aerogenerator central shaft, sheet metal and metal construction are with bolt.
Adopt link structure of the present utility model, improved the working life of vertical axis aerogenerator integral body greatly.Structure of the present utility model will make the antiseptic effect of moving element improve greatly, and the life-span was extended to more than 20 years.
