The model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of blade of vertical axis aerogenerator, and it has high capacity usage ratio under the high wind speed condition; And, also can improve the capacity usage ratio under low wind friction velocity.
For achieving the above object, the utility model adopts following technological scheme:
A kind of blade of vertical axis aerogenerator, comprise and be fairshaped outer arced surface, inner side surface; In the cross section of blade, the lower whorl profile of this inner side surface is provided with inner fovea part and forms on a lift-type streamline, this inner fovea part opening down; Described inner side surface comprises curved circular arc part, inclined plane part, and described inner fovea part is between circular arc part and inclined plane part; Arc transition between the front end of outer arced surface and the front end of circular arc part, and form termination section, the end of outer arced surface is connected with the end of inclined plane part, and forms afterbody.
Form a cavity between described outer arced surface and inner side surface, be provided with the supporting post be connected between outer arced surface and inner side surface in this cavity.
Inner side surface is provided with two inner fovea parts.
The interior base of inner fovea part and the angle of its front side edge are acute angle.
From the minimum point of circular arc part to inclined plane part, this lift-type streamline is the trend that raises gradually.
The blade of the vertical axis aerogenerator that the utility model is set forth, its beneficial effect is:
1, because outer arced surface adopts fairshaped design, and the lower whorl profile of inner side surface is provided with inner fovea part and forms on a lift-type streamline, can guarantee that it has high capacity usage ratio under the high wind speed condition; And inner side surface is by appropriate design, can be in the situation that do not increase reverse wind resistance, increase with aweather the thrust of blade, thereby improve its capacity usage ratio under low wind friction velocity;
2, form a cavity between outer arced surface and inner side surface, can effectively reduce the weight of blade, and can improve its intensity by supporting post, prevent from occurring in the post-production process profile line relative position generation drift condition of outer arced surface and inner side surface.
The accompanying drawing explanation
The structural representation of the blade that Fig. 1 is the utility model vertical axis aerogenerator;
The cross sectional representation of the blade that Fig. 2 is the utility model vertical axis aerogenerator;
Wherein, 1, outer arced surface; 2, inner side surface; 21, circular arc part; 22, inclined plane part; 23, inner fovea part; 231, interior base; 232, front side edge; 31, termination section; 32, afterbody; 4, supporting post; 5a, lift-type streamline.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the blade of the utility model vertical axis aerogenerator is described further, understand the utility model technical thought required for protection so that clearer.
Dotted line 5a in Fig. 2 shows the wherein shape of a kind of lift-type streamline 5a, and certainly, lift-type streamline 5a described in the utility model is not limited in this shape, also can adopt other to possess the shape of the streamline of lift effect.As shown in Figure 1, be the blade of a kind of vertical axis aerogenerator of the utility model, comprise and be fairshaped outer arced surface 1, inner side surface 2.As shown in Figure 2, in the cross section of blade, the lower whorl profile of inner side surface 2 is provided with inner fovea part 23 and forms on lift-type streamline 5a at one, this inner fovea part 23 opening down.Concrete, the interior base 231 of described inner fovea part 23 is acute angle with the angle of its front side edge 232.Described inner side surface 2 comprises curved circular arc part 21, inclined plane part 22, and described inner fovea part 23 is between circular arc part 21 and inclined plane part 22.Concrete, from the minimum point of circular arc part 21 to inclined plane part 22, this lift-type streamline 5a is the trend that raises gradually.Arc transition between the front end of the front end of described outer arced surface 1 and circular arc part 21, and form termination section 31, the end of outer arced surface 1 is connected with the end of inclined plane part 22, and forms afterbody 32.Because outer arced surface 1 adopts fairshaped design, and the lower whorl profile of inner side surface 2 is to be provided with inner fovea part 23 to form on a lift-type streamline 5a, can guarantee that it has high capacity usage ratio under the high wind speed condition.And inner side surface 2 is by rationally arranging, can be in the situation that do not increase the resistance of reverse wind (direction of described reverse wind blows to afterbody 32 from the termination section 31 of blade), can increase same aweather (described same direction aweather blows to termination section 31 from the afterbody 32 of blade) thrust to blade, thereby improve its capacity usage ratio under low wind friction velocity, enlarge its Applicable scope, increase total capacity usage ratio.
