Abstract
A vane of a minitype wind generator is made of wood or metal or engineering plastics or glass fiber reinforced plastics. The entire shape meets requirements of aerodynamics needed by the minitype wind generator. One surface or two surfaces of a tip of the vane are provided with reinforced ribs which are formed in an integrated mode and identical to the vane in materials. The structure of the vane reinforces the strength of the tip of the vane, enables the vane to be more durable, and effectively reduces noise.
Description
Technical field
The application relates to a kind of small-sized wind power generator blade.
Background technique
Blade is the parts of the most basic and most critical in the small-sized wind power generator, the design that it is good, reliably quality also superior performance be the determinant factor that guarantees the normal stable operation of unit.Rugged environment and for a long time ceaselessly running have the requirement of blade:
1. density is light and have best fatigue strength and mechanical property, can stand the test of the exceedingly odious condition such as storm wind and random load;
2. inertia and the vibration frequency characteristic curve thereof in the elasticity of blade, when rotation are all normal, the load stability that passes to whole power generation system is good, must not under downloading the effect of centrifugal force, the situation of (driving) out of control break and fly out, also must not under the effect of blast, fracture, also must not in the following scope of runaway speed, produce the strong resonance that causes whole wind power generating set;
3. the material of blade must guarantee smooth surface to reduce windage, and coarse surface also can " be torn " by wind;
4. must not produce the reflection of strong Electromagnetic Interference and light;
5. do not allow to produce excessive noise;
6. corrosion-resistant, ultraviolet irradiation and thunderbolt performance are good;
7. cost is lower, and maintenance cost is minimum.
As shown in Figure 1, 2, in the prior art, the material that is used for machining blade has wood, metal, engineering plastics, glass fibre reinforced plastics etc.At present on the market the blade design of small-sized wind power generator is in order to satisfy aerodynamic design principle, its blade tip all be and narrow have thin.
The external force that can bear of its blade was just little after blade tip was narrow, thin, and its intensity is just not enough, sometimes even can cause fracture.And because blade tip is too thin, can form resonance, blade will acutely be shaken like this, thereby forms very large noise.
Summary of the invention
For the defects that the prior art Leaf exists, it is a kind of for the small-sized wind power generator blade that the utility model provides.
The utility model provides a kind of small-sized wind power generator blade, described blade is made by wood, metal, engineering plastics or glass fibre reinforced plastics, described blade integral shape satisfies the required aerodynamics of wind-driven generator, has and the integrated stiffening rib of blade same material at the vane tip one or both sides.Wherein said stiffening rib can be arranged on the one side of vane tip into strips around the vane tip periphery.
Preferably at vane tip another side and described stiffening rib another stiffening rib in a symmetrical arrangement.
The utility model advantage is to strengthen blade tip intensity, makes blade more durable, and effectively reduces noise.

Embodiment
Further describe in detail below in conjunction with the described blade in accompanying drawing 3, the 4 pairs of the utility model.
Shown in Fig. 3,4, a kind of small-sized wind power generator blade 1, described blade is made by wood, metal, engineering plastics or glass fibre reinforced plastics, described blade integral shape satisfies the required aerodynamics of wind-driven generator, has and the integrated stiffening rib 2 of blade same material at the vane tip one or both sides.Wherein said stiffening rib can be arranged on the one side of vane tip into strips around the vane tip periphery.
Above embodiment does not limit claimed scope of the present utility model just to an illustrative example of the present utility model.
Claims (3)
1. small-sized wind power generator blade, described blade is made by wood, metal, engineering plastics or glass fibre reinforced plastics, described blade integral shape satisfies the required aerodynamics of wind-driven generator, it is characterized in that having and the integrated stiffening rib of blade same material at the vane tip one or both sides.
2. a kind of small-sized wind power generator blade according to claim 1 is characterized in that wherein said reinforcing rib ring is arranged on the one side of vane tip into strips around the vane tip periphery.
3. a kind of small-sized wind power generator blade according to claim 2 is characterized in that wherein at vane tip another side and above-mentioned stiffening rib another stiffening rib in a symmetrical arrangement.
