Abstract
The utility model discloses an aerogenerator honeycomb vane. The inner part is honeycomb plates which are fixed together, and is in the structure of a honeycomb; the outer surface of each honeycomb plate is provided with glass fiber and an epoxide resin layer. The aerogenerator honeycomb vane has the advantages of high intensity, light weight and low cost, thereby solving the bottleneck problem of the development of a high power aerogenerator, and being able to improve the efficiency of the existing aerogenerator highly.
Description
Technical field
The utility model relates to a kind of honeycomb blade of wind generator, belongs to the blade of wind-driven generator manufacture technology field.
Background technique
Because petroleum-based energy is in short supply day by day, people actively attempt utilizing other energy, and the development of Wind Power Utilization is especially rapid: wind-power electricity generation every year is all with 30% speed increment both at home and abroad, wherein the primary especially developing direction of high-power wind power generation.Demand mainly is other wind-driven generator of 3-10MW level on the present domestic and international market, and the pylon of this type wind-driven generator, the manufacturing technology of unit, inversion system are comparatively ripe, can both satisfy the demand in market.But powerful wind power generation blade length overlength, requirement of strength are high again, adopt following complex fiber material to make usually:
1, E, S glass fibre;
2, carbon fiber;
3, carbon, E glass mixed fibre;
4, carbon, wooden, E glass fibre;
5, thermoplastic resin;
6, E glass, bamboo fiber.
Though the blade that goes out with above-mentioned material can satisfy the usage requirement of high-power wind-driven generator, blade is very heavy, fabricating cost is high; Because himself is overweight, promotes its rotation and must expend many wind energies simultaneously, directly reduced the wind-powered electricity generation conversion ratio of wind-driven generator.These reasons cause the blade of wind-driven generator to become the bottleneck of high-power wind-driven generator development.
The model utility content
The purpose of this utility model is, provides the honeycomb blade of wind generator that a kind of intensity height, weight are light, fabricating cost is cheap, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it is fixed together by sheet honeycomb plate 1 at least and constitutes the blade skeleton, and the blade skeleton that constitutes at the honeycomb plate is coated with glass fibre and epoxy resin layer.
The thickness of every honeycomb plate is 0.5～3 centimetre.
The thickness of glass fibre and epoxy resin layer is 1～50 centimetre.
Bond together by adhesive between the honeycomb plate.
Owing to adopted technique scheme, compared with prior art, the main material honeycomb plate that the utility model uses can adopt the reworked material manufacturing, and very environmental protection is cheap, and has had this finished product to sell on the market; Adopting the honeycomb plate to make blade can make the blade manufacture cost reduce by 60%～80%; Because its inside is honeycomb structure, greatly reduce the overall weight (subordinate list 1 is the table of comparisons of 34 meters long blade of wind-driven generator weight of the present invention and the making of other conventional material) of blade again; The experiment proved that in addition honeycomb blade of wind generator toughness of the present utility model is suitable with the carbon fiber blade greater than glass fibre blade, intensity, can satisfy the usage requirement of high-power wind-driven generator fully.Honeycomb blade of wind generator intensity height of the present utility model, weight are low, with low cost, have solved the bottleneck problem of high-power wind-driven generator development, and great market application foreground is arranged, and use the present invention can improve the efficient of existing wind-driven generator than the highland.

Accompanying drawing 1 is a structural representation of the present utility model.
Reference character: 1, honeycomb plate; 2, glass fibre and epoxy resin layer; 3, adhesive.
Embodiment
Embodiments of the invention 1: be less than or equal to 20 meters blade for length, be by weight: the raw material of 80 parts of honeycomb plates (thickness of every honeycomb plate is 0.5～3 centimetre), 10 parts of adhesive (as the L-02 neoprene phenolic adhesive), 20 parts in glass fibre (as the E-alkali-free glass fibre), 20 parts of epoxy resin (as 6101 epoxy resin) are made honeycomb blade, whittle shape so an amount of honeycomb plate that increases is beaten the part of pruning to replenish because of beating the honeycomb plate in making.The honeycomb plate is bonded together with the L-02 neoprene phenolic adhesive, and the mode by artificial or machine treatment is shaped to blade shape then, smears on the surface of this blade to cover upper glass fiber and epoxy resin again.
Embodiments of the invention 2: for the blade of length greater than 20 meters, be by weight: the raw material of 50 parts of honeycomb plates (thickness of every honeycomb plate is 0.5～3 centimetre), 40 parts of adhesive (as the L-02 neoprene phenolic adhesive), 30 parts in glass fibre (as the E-alkali-free glass fibre), 30 parts of epoxy resin (as 6101 epoxy resin) are made honeycomb blade, whittle shape so an amount of honeycomb plate that increases is beaten the part of pruning to replenish because of beating the honeycomb plate in making.The honeycomb plate is bonded together with the L-02 neoprene phenolic adhesive, and the mode by artificial or machine treatment is shaped to blade shape then, smears on the surface of this blade to cover upper glass fiber and epoxy resin again.
