Abstract
The utility model relates to a kind of blade of wind-driven generator, comprise blade part and leaf tip, blade part is hollow structure inside and is the wing shape of torsion or the planar of torsion, the angle that blade part rear and front end is reversed is 10 ~ 35 °, leaf tip is the wing shape or the planar of torsion that reverse, and the angle reversed than blade part rear and front end of the angle reversed of leaf tip rear and front end is large and angle that the is torsion of leaf tip rear and front end is less than 90 °; The outer surface of blade part and leaf tip has flame retardant coating, corrosion-resistant finishes and insulation coating.Blade of wind-driven generator of the present utility model is anticorrosive, anti-lightning strike, and can start when wind-force is less.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator
,belong to technical field of wind energy utilization.
Background technique
Wind power generating set, can divide wind wheel (comprising tail vane), generator and steel tower three part substantially.Wind wheel is the kinetic energy of keeping watch is the vitals of mechanical energy, and it is made up of the impeller of two (or more only) propeller shapes.When wind is to blade, blade produces aerodynamic force and drive wind wheel to rotate.The material requirements intensity of blade is high, lightweight, and current multiplex glass fibre reinforced plastics or other composite material (as carbon fiber) manufacture.
Blade is parts that are the most basic in wind-driven generator and most critical, its good design, and reliable quality also has superior performance to be the determinant factor ensureing that unit normal table runs.Blade need use the light material of density to make and should have best fatigue strength and mechanical property, can stand the test of the exceedingly odious conditions such as storm wind and Random Load; Simultaneously corrosion-resistant, the Ultraviolet radiation of blade and thunderbolt performance will be got well.
The blade of the horizontal-shaft wind turbine of prior art is the lift-type blade for wing shapes, blade is more straight, windup-degree is less, use the wind energy conversion system of such blade when wind speed is less than threshold wind velocity, can not start, and when wind speed is greater than rated wind speed, if do not take additional measures, so rotating speed is too fast, easily causes the destruction of the even whole mechanical structure of blade.
Model utility content
The technical problems to be solved in the utility model is, proposes a kind of anticorrosive, anti-lightning strike little wind speed and bootable blade of wind-driven generator.
The utility model is the technological scheme solving the problems of the technologies described above proposition, a kind of blade of wind-driven generator, comprise blade part and leaf tip, described blade part is hollow structure inside and is the wing shape of torsion or the planar of torsion, the angle that blade part rear and front end is reversed is 10 ~ 35 °, leaf tip is the wing shape or the planar of torsion that reverse, and the angle reversed than blade part rear and front end of the angle reversed of leaf tip rear and front end is large and angle that the is torsion of leaf tip rear and front end is less than 90 °; The outer surface of described blade part and leaf tip has flame retardant coating, corrosion-resistant finishes and insulation coating.
Being improved to of technique scheme: the angle staggered in blade part rear and front end is 25 °.
Being improved to of technique scheme: the angle staggered in leaf tip rear and front end is 50 °.
Being improved to of technique scheme: described flame retardant coating is for containing Flame Retardant Unsaturated Polyester Resin coating.
Being improved to of technique scheme: described corrosion-resistant finishes is the coating containing carbamide paint or polyurethane.
Being improved to of technique scheme: described insulation coating is the coating containing aluminium metaphosphate.
The beneficial effects of the utility model are:
1, because blade part hollow, reduce the overall weight of blade, make it also can rotate when wind-force is less.
2, the angle that the angle reversed due to leaf tip rear and front end is reversed than blade part rear and front end is large, when wind speed is below rated wind speed, the rotary driving force square that leaf tip produces is greater than steering resistance square, not only be conducive to the startability improving wind energy conversion system, and can wind speed round be improved, improve generated energy; When wind speed is greater than rated wind speed, wheel speed is fast, and the rotary driving force square that leaf tip produces is less than steering resistance square, and the rotating speed of restriction wind wheel, can not damage whole mechanical structure because rotating speed is too fast.
3, the outer surface of blade part and leaf tip has flame retardant coating, corrosion-resistant finishes and insulation coating, can effectively prevent blade from receiving the corrosion and thunderbolt etc. of external environment condition.
