Abstract
The utility model provides a vertical axis wind turbine blade structure, includes the blade body, the exhibition of blade body is same wing section to each cross -section, and the exhibition of this blade body is the isometric distribution of non - to the chord length in each cross -section, and the leading edge in each cross -section is located same straight line. The utility model discloses simple structure, preparation are convenient, greatly reduced the degree of difficulty and the production manufacturing cost of structure to wind energy utilization efficiency, generated power have been improved.
Description
Technical field
The utility model relates to wind power generating set, particularly relates to a kind of vertical axis wind power generation blade structure.
Background technique
The blade of wind-power electricity generation is divided into two kinds usually, and one is horizontal axis wind generating blade, the general structural type adopting different airfoil profiles different chord lengths more; Another kind is vertical axis wind power generation blade, much more general adopt same aerofoil profile and etc. the structural type of chord length.
Vertical axis aerogenerator group need not become oar and driftage, and structure is relatively simple, is currently used widely gradually in middle-size and small-size wind power generation field.But blade structure is unreasonable, have impact on the utilization ratio of wind, generated output not to the utmost, more have impact on the cost of blade and the anatomical connectivity difficulty of vertical axis aerogenerator group.
Model utility content
Based on this, for above-mentioned technical problem, provide a kind of vertical axis wind power generation blade structure.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of vertical axis wind power generation blade structure, comprise blade body, the exhibition of described blade body is same aerofoil profile to each cross section, and the exhibition of this blade body is non-isometric distribution to the chord length in each cross section, and the leading edge in each cross section is located on the same line.
The chord length chord length that is the longest, that be positioned at two ends that the exhibition of described blade body is positioned at middle part in the chord length in each cross section is the shortest.
The utility model structure is simple, easy to make, greatly reduces difficulty and the manufacturing cost of structure, and improves wind energy utilization efficiency, generated output.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Fig. 1 look up structural representation.
Embodiment
As shown in Figure 1 and Figure 2, a kind of vertical axis wind power generation blade structure, comprises blade body 110.
The exhibition of blade body 110 is same aerofoil profile to each cross section 111, and the exhibition of this blade body 110 is to the chord length 112 in each cross section 111 in non-isometric distribution, and the leading edge in each cross section is located on the same line.
Adopt the vertical axis aerogenerator group of the blade of the utility model structure, the position that only need support arm is the longest with blade body 110 chord length carries out being connected, and greatly reduces the difficulty of structure.Meanwhile, due to non-isometric chord length distribution, greatly reduce the production material consumption of blade, thus reduce the manufacturing cost of blade; Due to the chord length distribution such as non-, when low wind speed, the region that mainly chord length is large is stressed, when high wind speed, the region that mainly chord length is little is stressed, and the region that now chord length is large more makes to provide structural strength to support, thus, improve wind energy utilization efficiency, generated output.
Preferably, the chord length chord length that is the longest, that be positioned at two ends that the exhibition of blade body 110 is positioned at middle part in the chord length 112 in each cross section is the shortest, constructive difficulty and manufacturing cost lower, further increase wind energy utilization efficiency, generated output.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
Claims (2)
1. a vertical axis wind power generation blade structure, it is characterized in that, comprise blade body, the exhibition of described blade body is same aerofoil profile to each cross section, the exhibition of this blade body is non-isometric distribution to the chord length in each cross section, and the leading edge in each cross section is located on the same line.
2. a kind of vertical axis wind power generation blade structure according to claim 1, is characterized in that, the chord length chord length that is the longest, that be positioned at two ends that the exhibition of described blade body is positioned at middle part in the chord length in each cross section is the shortest.
