Abstract
The utility model discloses a fan blade for a vertical axis wind-driven generator, which comprises two or three strip-shaped bowed blades and a supporting structural frame, wherein, the strip-shaped bowed blades are parallel to the vertical axis of the wind-driven generator; the supporting structural frame is combined with the vertical axis of the wind-driven generator so as to form a whole body; fixing holes are formed at the upper ends of the lower ends of the strip-shaped bowed blades; and the supporting structural frame is fixed on the fixing holes so as to form an arch. The fan blade is characterized in that the strip-shaped bowed blades are flexible strip-shaped bowed blades; the transverse section of each strip-shaped bowed blade is in the shape of a shuttle; the thickness of the weather side (the wind-driven surface of each strip-shaped bowed blade) is greater than that of the both sides of each strip-shaped bowed blade; and the cross-sectional area of the weather side is greater than that of the both sides of each strip-shaped bowed blade. The weather side can easily drive the vertical axis of the wind-driven generator to rotate in the setting direction when pushed by wind, the wind power is utilized to perform energy conversion effectively, and wind resources can be utilized fully. Particularly, the fan blade can bear the strong wind impact for a long time, can effectively reduce the abrasion on the fan blade caused by wind power, and has the advantages of low stress, small material utilization, low probability of fracture and long service life.
Description
Technical field
The utility model relates to the generator flabellum, especially relates to a kind of vertical axis aerogenerator flabellum.
Background technique
The vertical axis aerogenerator flabellum is used to accept wind-force and transfers electric energy to by head, is the vitals of wind-driven generator with the wind energy transformation electric energy.The flabellum of existing vertical axis aerogenerator is to adopt the glass fibre molding and forming mostly, and the cross-section is the face of no gradual change, there is short problem in working life, particularly try hard to recommend action and can not drive the generator vertical shaft time spent easily and rotate, can not effectively utilize wind-force to carry out transformation of energy at wind-engaging.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned defective that remedies prior art, proposes a kind of vertical axis aerogenerator flabellum.
Technical problem of the present utility model is solved by the following technical programs.
This vertical axis aerogenerator flabellum, comprise 2～3 bar shaped bent blades parallel with the generator vertical shaft, and with the generator vertical shaft be the supporting frame of one, the upper and lower end of described bar shaped bent blades is respectively equipped with fixed hole, fixedly is arciform with described supporting frame, rotates around the generator vertical shaft, the wind energy of accepting any direction is converted to mechanical work, and do not need to follow the tracks of the yawing mechanism of wind direction, and can stand long-term high wind effect, effectively alleviate the wearing and tearing of wind-force to the bar shaped bent blades.
The characteristics of this vertical axis aerogenerator flabellum are:
Described bar shaped bent blades is the flexible bar type bent blades, forms no moment of flexure stress curve around the rotation of generator vertical shaft.
The cross-section of described bar shaped bent blades is to spin shuttle shape cross-section, the windward side be the wind-engaging focusing surface thickness of bar shaped bent blades greater than thickness of two sides, and the windward side cross-sectional area is greater than the cross-sectional area of both sides.Try hard to recommend action when the windward side wind-engaging and the time spent can drive the generator vertical shaft easily and rotate, effectively utilize wind-force to carry out transformation of energy, make full use of wind-resources towards direction initialization.
Preferably, the described bar shaped bent blades aluminum alloy bar section bar bent blades that is the thin-walled hollow structure.
Preferably, described thin-walled hollow structure is the thin-walled hollow structure that is provided with stiffening rib.
Preferably, described stiffening rib is that the cross-section is the stiffening rib of C shape.
Preferably, the windward side thickness of described bar shaped bent blades is greater than 1.0～1.2 centimetres of thickness of two sides.
The beneficial effect that the utility model is compared with the prior art is:
The utility model is based on the plasticity of aluminum alloy, the windward side thickness of the bar shaped bent blades parallel with the generator vertical shaft is greater than thickness of two sides, and the windward side cross-sectional area is greater than the cross-sectional area of both sides, trying hard to recommend action when the windward side wind-engaging can drive the generator vertical shaft easily rotate towards direction initialization the time spent, effectively utilize wind-force to carry out transformation of energy, make full use of wind-resources.Especially can stand long-term high wind effect, effectively alleviate the wearing and tearing of wind-force flabellum, have stressed little, materials are few, the advantage of frangibility, long service life not.
Description of drawings
Fig. 1 is the bar shaped bent blades cross-section schematic representation of the utility model embodiment;
Fig. 2 is the package assembly schematic representation of bar shaped bent blades in the wind-driven generator of magnetic suspension wind power generation road lamp of Fig. 1.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing, the utility model is made an explanation.
The wind-driven generator flabellum of the magnetic suspension wind power generation road lamp that shows as Fig. 1 to Fig. 2 comprises three bar shaped bent blades 1 parallel with the generator vertical shaft, and with the generator vertical shaft be the supporting frame 2 of one.Supporting frame 2 is installed in the top of magnetic suspension wind Power Generation Road lamppost.
Bar shaped bent blades 1 is that thin-walled hollow is provided with the aluminum alloy flexible bar type bent blades that the cross-section is stiffening rib 5 structures of C shape, and upper and lower end is respectively equipped with fixed hole, fixedly is arciform with supporting frame 2, rotates around the generator vertical shaft.
The cross-section of bar shaped bent blades 1 is to spin shuttle shape cross-section, windward side 3 be the wind-engaging focusing surface thickness of bar shaped bent blades 1 greater than 1.1 centimetres of both sides 4 thickness, and windward side 3 cross-sectional areas are greater than the cross-sectional area of both sides 4.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be considered as belonging to protection domain of the present utility model.
