Abstract
A kind of H type vertical axis wind electric unit blade structure, the load that solution blade bears is not corresponding with self-strength, the blade that low wind speed starts, the technical problem that leaf weight is large, the scheme adopted is that the shape of blade is: with center, length of blade direction for benchmark is to both sides, the major axis H of the transverse section of blade
1in the structure diminished gradually.Beneficial effect is that vane stress is corresponding with the intensity of himself, low wind speed district blade transverse section major axis H
1longer region is main force part, blade transverse section, high wind speed district major axis H
1shorter region is main force part, greatly changes the overall performance of unit and reduces the weight of blade and unit, reducing manufacture cost.
Description
Art
The utility model belongs to wind power plant mechanism, particularly a kind of H type vertical axis wind electric unit Leaf structure.
Background technique
In prior art, H type vertical axis wind electric unit Leaf structure adopts prismatic blade structure, namely blade is consistent in the transverse shape of length direction, one group of blade is vertically mounted on land through blade supporting arm respectively, land is connected with generator set input shaft, generator set is arranged on pylon, and blade drives land that generator set is rotated under wind-force effect, realizes generator set and rotates generating.
In H type vertical axis wind electric unit, even if the main stressed member of blade, determine the critical component of H type vertical axis wind electric unit generating efficiency especially, blade in design principle is, under the prerequisite ensureing blade strength simultaneously, increase its stress surface windward as far as possible, rotate to meet land drive electrical generators group, ensure the generating efficiency of group of motors, in prior art, in H type vertical axis wind electric unit, be adopt the transverse section of blade to be the major axis H of equal length
1structure, this structure blade, for ensureing that low wind speed starts, must ensure the major axis H of blade transverse section
1have certain length, the shortcoming of this blade structure is, the major axis H of blade transverse section
1contradiction between length and leaf weight, simultaneously the blade load of bearing is not corresponding with self-strength, as needs ensure that blade can start by low wind speed, leaf weight is caused to increase, strengthen manufacture cost, blade supporting arm and pylon require higher intensity simultaneously, strengthen the manufacture cost of blade supporting arm and pylon.
Model utility content
For overcoming in prior art, the transverse section of the blade adopted in H type vertical axis wind electric unit is the major axis H of equal length
1the above-mentioned technical deficiency that structure is brought, the utility model discloses a kind of H type vertical axis wind electric unit Leaf structure.Solve above-mentioned the deficiencies in the prior art.
The technological scheme that the utility model technical solution problem adopts is that the shape of blade is: with center, length of blade direction for benchmark is to both sides, the major axis H of the transverse section of blade
1in the structure diminished gradually.
The beneficial effects of the utility model are, vane stress is corresponding with the intensity of himself, low wind speed district blade transverse section major axis H
1longer region is main force part, blade transverse section, high wind speed district major axis H
1shorter region is main force part, greatly changes the overall performance of unit and reduces the weight of blade and unit, reducing manufacture cost.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram.
Accompanying drawing 2 is accompanying drawing 1 schematic cross-sectional view.
Accompanying drawing 3 is accompanying drawing 1 plan view.
Accompanying drawing 4 is the utility model use schematic diagram.
In accompanying drawing, 1 blade, 2 blade supporting arms, 3 lands, 4 generator set, 5 pylons.
Embodiment
Referring to accompanying drawing, a kind of H type vertical axis wind electric unit blade structure, blade 1 is fixed on land 3 through blade supporting arm 2, and land 3 is coaxially connected with generator set 4, and generator set 4 is fixedly supported on pylon 5.
The shape of described blade 1 is: with center, length of blade direction for benchmark is to both sides, the major axis H of the transverse section of blade 1
1in the structure diminished gradually.
During use, major axis H
1in the ratio diminished gradually, the situation design of the wind field situation used according to H type vertical axis wind electric unit.
The blade 1 of this structure is stressed corresponding with the intensity of himself, and heart position is in the trend increased gradually wherein for the two ends of blade 1, and the self-strength of blade 1 is corresponding with it.
Low wind speed district blade transverse section major axis H
1longer region is main force part, blade transverse section, high wind speed district major axis H
1shorter region is main force part.
In the utility model embodiment, the wind field situation that can use according to H type vertical axis wind electric unit, the shape of described blade 1 is: with center, length of blade direction for benchmark is to both sides, the transverse section minor axis H of blade 1
2in the structure diminished gradually.
In the utility model embodiment, the wind field situation that can use according to H type vertical axis wind electric unit, the shape of described blade 1 is: with center, length of blade direction for benchmark is to both sides, the major axis H in transverse section of blade 1
1with minor axis H
2the structure diminished gradually in equal proportion.
