Embodiment
Below in conjunction with accompanying drawing mode of execution of the present utility model is described further.
Consult Fig. 1, Fig. 2, vertical wind driven generator 6 is installed in column 8 tops, central sleeve 4 is installed in wind-driven generator 6 tops, stator axis 7 upper ends pass the mesopore of central sleeve 4, evenly be provided with on the external cylindrical surface of central sleeve 4 and be connected and fixed 4 substantially horizontal fan blade poles 3, interior end bearing Z is fixed on the central sleeve 4 by rivet M, fan blade pole 3 stage casings welding fixed vertical stand 5, stand 5 is made by straight rectangular metal plate, and epimere is connected hinge 2 with hypomere with screw.Hinge 2 is connected with screw with the inner of fan blade 1.Fan blade 1 protrudes arch face and withstands support by fan blade pole 3 for the rectangular slab of band arc arch face, back, and the front arc-shaped concave is in and is subjected to force direction down with the wind.No matter wind from which direction comes, fan blade 1 all can the wind-engaging rotation, and the rotor shell 11 that drives wind-driven generator 6 is rotated generating, and fan blade 1 is connected by hinge 2 with stand 5, fan blade 1 and stand 5 be connected angle 90 ° with interior change, can freely swing 90 °.When wind to fan blade 1, behind the intrados wind-engaging, hinge 2 merges, fan blade 1 leans against fan blade pole 3, supports wind-engagings by fan blade pole 3 and forms power.The back side that rotates to fan blade 1 is forward the time, and the back side of wind fan blade 1 is supported because of fan blade 1 front has fan blade pole 3, and hinge 2 opens, and forms the opening angle between fan blade 1 and the fan blade pole 3, and wind-receiving face reduces, and promptly resistance reduces.When fan blade 1 forwards the front to forward, arc-shaped concave wind-engaging, fan blade 1 be by to after-blow, hinge 2 closures, and support is withstood by fan blade pole 3 in fan blade 1 back side, and wind-engaging forms power, and the rotor shell 11 that drives wind-driven generator 6 is rotated.
Consult Fig. 3, wind-driven generator 6 is to be equipped with rotor shell 11 by stator axis 7 to constitute, and stator axis 7 maintains static, and rotor shell 11 is rotated, and cutting magnetic line generates electricity.Central sleeve 4 is sleeved on rotor shell 11 upper end portion electric motor end caps 10 outsides, has cotter way on central sleeve 4 inwalls, and is corresponding with the cotter way on electric motor end cap 10 outer walls, and the embedded dress connecting pin 9 of cotter way clamps central sleeve 4 and electric motor end cap 10 fixing.Some fan blade poles 3 evenly are set on central sleeve 4 external cylindrical surfaces, by rivet M the bearing Z of fan blade pole 3 the inners are installed on central sleeve 4 outer walls, the stage casing, outer end of fan blade pole 3 connects stand 5, connects fan blade 1 with hinge 2.When fan blade 1 is moved in wind, fan blade 1 promotes central sleeve 4 and rotates, drive rotor shell 11 rotations of wind-driven generator 6 by electric motor end cap 10, with the coil generation electromagnetic induction on the stator axis 7, cutting magnetic line generates electricity, and the fan blade 1 arcuation concave surface wind-engaging that facings the wind is swung backward, and hinge 2 is incorporated on the hinge 2 of stand 5, fan blade pole 3 is supported fan blade 1 rearward, and fan blade 1 wind-engaging forms power.When fan blade 1 rotates to opposite side, when being facingd the wind forward by the domed back side, because the front arc-shaped concave of fan blade 1 does not have fan blade pole 3 to support, wind swing hinge 2 is opened, formation acute angle angle between fan blade 1 and the fan blade pole 3, and wind-exposuring area reduces, and has reduced resistance.Continue rotating blading 1, arc-shaped concave facings the wind, and fan blade 1 is freely swung by wind, and hinge 6 is amounted to, and fan blade 1 back arch face obtains the support of fan blade pole 3, the arc-shaped concave wind-exposuring area maximum of fan blade 1, and the power of generation is big, can make full use of wind energy.
The utility model is suitable for using in the little hinterland of wind-force, as long as reach rotor shell 11 rotations that the wind speed of 1 meter of per second can drive wind-driven generator 6. starting wind velocity requires low, the wind energy utilization height, operating cost is low, the generating efficiency height, low-carbon (LC), energy-saving and environmental protection, economic benefit and social benefit are good.
