Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly a kind of small-sized vertical axis aerogenerator that is suitable for family's use.
Background technique
General wind-driven generator comprises generator, column, impeller, and described generator places on the described column, and described impeller set is connected on the running shaft of described generator.The wind-driven generator that is suitable for family's use that occurs on the Domestic market at present all is horizontal shaft type, be that described generator is when being installed on the column, the running shaft of described generator becomes level, described impeller is roughly parallel with described column, this wind-driven generator takes up room bigger, wind energy utilization is low, noise is big, often will consider the influence of windward side when installing, and wind loading rating is relatively poor, the leaf oar blows disconnectedly easily, and (3.5 meter per seconds are following) is difficult to work under the lower situation of wind speed.Vertical axis aerogenerator, be that described generator is when being installed on the column, the running shaft of described generator becomes vertical state, described impeller is roughly vertical with described column, through development after a while, the accumulation of a little technology has progressively been arranged, but the vertical axis aerogenerator power of design is all bigger now, and described generator running shaft connects outside the space that makes described generator be positioned at described impeller formation with described impeller hub by another major axis, like this under the effect of wind energy, can produce the stress of comparatively concentrating on described generator running shaft, consumptive material is more, and power coefficient is not satisfactory; In addition, blade on the described impeller and wheel hub connection all are to extend outside radially along wheel hub basically, and this design also can be easy to generate the reversing phenomenon as not taking special measure; Starting wind speed requires also higher.And, also be not suitable for the small-sized vertical axis aerogenerator that family uses at present.
The model utility content
The purpose of this utility model just is to provide a kind of small-sized vertical axis aerogenerator that can be suitable for domestic. applications.
The purpose of this utility model is achieved by the following technical solution: a kind of small-sized vertical axis aerogenerator, comprise generator, impeller, column, described generator places on the described column top, the running shaft of described generator vertically upward, described impeller set is connected on the described generator running shaft; Described impeller comprises blade and wheel hub, and described blade links to each other by a camber arch shape horizontal axis with impeller hub.
With described center hub central point is that initial point is set up system of coordinates XOY on the horizontal central cross-section of described impeller, it is the circle in the center of circle with the initial point that the projection on described system of coordinates XOY of described camber arch shape horizontal axis center line and described center hub external frame forms a curve, one, if the binding site of described blade and described horizontal axis is positioned at the first quartile of system of coordinates XOY, the intersection point of then described curve and circle is positioned at second quadrant or the third quadrant of system of coordinates XOY.
With the horizontal central cross-section of described impeller is benchmark, and described generator has at least part to go to the bottom between the horizontal plane that the edge forms at the horizontal central cross-section of described impeller and described impeller.
When described camber arch shape horizontal axis has definite center line, the binding site of described camber arch shape horizontal axis center line and described wheel hub in described system of coordinates projection and the line of described initial point and the angle between the transverse axis in the described system of coordinates between the 90-270 degree.
When the cross section of described camber arch shape horizontal axis is " T " font of lying on one's side, the center of the junction plane of described camber arch shape horizontal axis " T " word cross section and described wheel hub in described system of coordinates projection and the line of described initial point and the angle between the transverse axis in the described system of coordinates between the 90-270 degree.
Because the utility model has also adopted the connection set of camber arch shape horizontal axis as blade and impeller hub, make impeller the phenomenon of reversing can not occur because of the change of wind direction; Because the strength ratio of described camber arch shape horizontal axis is bigger, when being subjected to bigger wind-force, blade can not taking place blow to discount and resemble; Because it is the utilization of described camber arch shape horizontal axis makes the starting wind velocity of described generator reduce significantly, quite favourable to the utilization of wind energy.In addition because the utility model has adopted to the described master section of major general places in the encirclement that described impeller forms, the stress that makes the binding site of described generator running shaft and described impeller hub be subjected to reduces significantly; Make the ability of its antifatigue obtain enhancing, the equipment physical life increases.
