Embodiment
The specific embodiment that the utility model adopted will be further described by following embodiment and accompanying drawing.
See also Fig. 1 and Fig. 2, Fig. 1 is for showing the schematic representation of the utility model wind power generation structure, and Fig. 2 shows fan housing stereogram of the present utility model.As shown in the figure, wind power generation structure 100 comprises a fan housing 1 and a blade structure 2.Fan housing 1 is an awl cylindrical structure, and fan housing 1 has a plurality of to be arranged at the air-guiding hole 11 of fan housing 1 lateral margin around mode, in order to a wind stream F is imported from the air-guiding hole 11 of fan housing 1.
See also Fig. 3 and Fig. 4 simultaneously, Fig. 3 is for showing the stereogram of blade structure of the present utility model, and Fig. 4 is for showing the top view of blade structure of the present utility model.As shown in the figure, blade structure 2 comprises that rotating shaft 21 and multilayer are to be arranged at fan blade layer 22a, 22b, 22c, the 22d of rotating shaft 21 around mode.Each fan blade layer 22a, 22b, 22c, 22d have six respectively by 21 extended fan blades 221 of rotating shaft.Wherein, the fan blade 221 of blade structure 2 is the fan blade of an arc, and fan blade 221 has the space 221 that facings the wind, and in order to blowing fan blade 221 as wind stream F, the space 222 that facings the wind by fan blade 221 can increase wind stream F and fan blade 221 area of contact.
When a wind stream F blows blade structure 2, because each fan blade layer 22a, 22b, 22c, 22d are to be arranged at around mode in the rotating shaft 21, and has one first predetermined angle theta 1 between same fan blade layer 22a, 22b, 22c, each contiguous fan blade 221 of 22d, in addition, between each fan blade layer 22a, 22b, 22c, the 22d is non-overlapped setting, so that the fan blade 221 of each fan blade layer 22a, 22b, 22c, 22d all has different directivity with respect to rotating shaft 21.As shown in Figure 4, by the top view angle, each fan blade layer 22a, 22b, 22b, 22c, 221 of the fan blades that each of 22c, 22d is adjacent have second an identical predetermined angle theta 2, so that each fan blade 22 equal distribution of each fan blade layer 22a, 22b, 22c, 22d are on the plane perpendicular to rotating shaft 21.Therefore when wind stream F blows the fan blade 22 of blade structure 2, having at least one fan blade 221 is subjected to wind stream F and blows and drive rotating shaft 21 rotation, moreover, because each fan blade 221 has the space 222 that facings the wind, therefore when wind stream F blows fan blade 221, can increase the area of contact of wind stream F and fan blade 221, make fan blade 221 can be subjected to wind stream F easily and blow and drive rotating shaft 21 rotation.
See also Fig. 5, it shows that the utility model wind power generation structure is incorporated into the schematic representation of generator.As shown in the figure, the rotating shaft 21 of wind power generation structure 100 of the present utility model is incorporated into a generator 3, when a wind stream F blowed to fan housing 1, at this moment, the air-guiding hole 11 that is positioned at fan housing 1 lateral margin can be imported wind stream F.After wind stream F imported from the air-guiding hole 11 of fan housing 1, the fan blade 221 that is arranged at the blade structure 2 of fan housing 1 inside can blow and drive rotating shaft 21 rotations because be subjected to wind stream F, and then drives generator 3 generatings that are connected in rotating shaft 21.
In addition, because the fan housing 1 of wind power generation structure 100 is the awl cylindrical structure of a base diameter greater than top diameter, therefore when wind stream F blows the fan blade 221 of blade structure 2, blade structure 2 in the rotation can be directed to each fan blade layer 22a with partial Upwind air-flow F, 22b, 22c, the 22d bottom, and form whirlpool air-flow F1, instantly whirlpool air-flow F1 is from each fan blade layer 22a, 22b, 22c, when 22d flows through the bottom, following whirlpool air-flow F1 can produce a stablizing effect to blade structure 2, and derived via the air-guiding hole 11 that is positioned at fan housing 1 opposite side, produce because of rotation with blade structure 2 in avoiding rotating and the generator 3 that is connected in rotating shaft 21 and rock.
By above embodiment as can be known, the value on the true tool industry of wind power generation structure provided by the utility model was so the utility model had accorded with the requirement of patent already.But above narration only is preferred embodiment explanation of the present utility model, allly be skillful in this skill person when can doing other all improvement, but these changes belong to still in creation spirit of the present utility model and the following claim scope that defines according to above-mentioned explanation.
