Description
Technical field
The present invention relates to a kind of screw type blade of wind-driven generator.It is a kind of Sa Woniusi (Savonius) spiral shape wind-force
Generator blade.Belong to technical field of wind power generation.
Background technology
Traditional Sa Woniusi screw types blade of wind-driven generator is typically by aluminum alloy thin steel plate or conventional composite ratio
As reinforced plastic glass fibre is made, the power face and resistance surface roughness of blade are basically identical, therefore can only rely on intrinsic knot
Structure produces thrust, and fails to make power face produce more pressure differentials with resistance area.So as to cause the utilization ratio of wind energy relatively low.
According to aerodynamic principle, the surface of distinguished and admirable warp is more coarse, and blast is reduced more, namely the surface receives
More blast, as shown in Figure 5.According to formula P0-P=P1, for P closer to P0, P1 is smaller, illustrates that wind energy more changes into
The thrust of fan blade, and the wind energy escaped is fewer.
Similarly, surface is more smooth, and wind energy is escaped more, and the kinetic energy for acting on fan blade surface is smaller.And traditional wind-force
Generator blade surfaces externally and internally Just because of this defects of cause the utilization ratio of wind energy relatively low.
The content of the invention
It is an object of the invention to provide a kind of screw type blade of wind-driven generator that can improve wind energy utilization efficiency.
Realizing above-mentioned purpose technical scheme is：A kind of screw type blade of wind-driven generator, including with inner surface and appearance
The blade body in face, inner surface is as power face, and as resistance area, outer surface is to be provided with smooth surface inner surface for outer surface
Warp and weft, and form grid surface by warp and weft.
Further, the width of described parallel is more than the width of warp.
Further, the width of the parallel is through 3~5 times of line width.
After employing above-mentioned technical proposal, in order to increase the thrust of power face, while reduce the resistance of resistance area, in fan blade
Inner surface be power face set warp and weft, and by warp and weft formed grid surface, significantly increase power face
Roughness, and outer surface is resistance area makes smooth surface.The warp of inner surface is more tiny simultaneously, and parallel is more abundant,
This is the inner surface in order to allow space of the wind energy escaped out more between two blades to act on another blade
That is power face, using such a inner surface be grid surface and latitude and longitude have thickness point fan blade after, drastically increase wind energy and turn
The effect of mechanical energy is melted into, wind energy utilization efficiency is improved, after (simple) wind tunnel test, 15% or so efficiency can be improved.

Embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail.
As shown in figures 1-4, a kind of screw type blade of wind-driven generator, including with inner surface 1-1's and outer surface 1-2
Blade body 1, inner surface 1-1 is as power face, and outer surface 1-2 is as resistance area, and outer surface 1-2 is smooth surface, inner surface
Warp 2 and parallel 3 are provided with 1-1, and grid surface is formed by warp 2 and parallel 3.
As shown in figure 4, the width of described parallel 3 is more than the width of warp 2
As shown in figure 4, the width of the parallel 3 is 3~5 times of 2 width of warp.
The operation principle of the present invention is as follows：
In order to increase the thrust of power face, while reduce the resistance of resistance area, the present invention is i.e. dynamic in the inner surface 1-1 of fan blade
Power face sets warp 2 and parallel 3, and forms grid surface by warp 2 and parallel 3, significantly increases the roughness of power face,
And outer surface 1-2 is resistance area makes smooth surface.Inner surface 1-1 warp 2 is more tiny simultaneously, and parallel 3 is more abundant, this
Be in order to allow space of the wind energy escaped out more between two blades act on another blade inner surface namely
Power face, using such a inner surface be grid surface and latitude and longitude have thickness point fan blade after, drastically increase wind energy transformation
Into the effect of mechanical energy, wind energy utilization efficiency is improved, after (simple) wind tunnel test, 15% or so efficiency can be improved.
Particular embodiments described above, the purpose of the present invention, technical scheme and beneficial effect are carried out further in detail
Describe in detail it is bright, should be understood that the foregoing is only the present invention specific embodiment, be not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., it should be included in the guarantor of the present invention
Within the scope of shield.
