As shown in Figure 1, wind turbine includes more blades 1, blade 1 has certain radian, can make exhaust air rate bigger, arcwall face
Direction is consistent with centrifugal direction, and the top surface of blade 1 is inShape, top surface outside (outer blade diameter direction) is relatively low, is bond end,
It is internal higher, it is inserted terminal 4, overhead gage 2 is equipped with slot identical with blade quantity, and slot shape is identical as 1 shape of blade,
Inserted terminal 4 passes through overhead gage 2 through slot upwards from the bottom of overhead gage 2, and protrudes from the upper surface of overhead gage 2, the end of slot
The end with inserted terminal 4 is held to offset, the top surface of bottom surface and bond end of the overhead gage 2 on rear side of slot mutually overlaps, thus will be upper
Baffle 2 realizes that the overlap joint after grafting is fixed with blade 1, to further fix, overhead gage 2 in wind turbine operation process is avoided to fall off,
In the top surface of overhead gage 2, the both sides of inserted terminal 4 will be welded and fixed at inserted terminal 4 and slot again with the mode of spot welding.
Blade 1 is welded and fixed on lower baffle plate 3, and the inner end of blade forms a circle, correspondingly, blade outboard end is same
Sample is circle, and blade overhead gage 2 is less than the width (length from the inside to the outside) of blade in annular shape, overall width, wherein as schemed
Shown in 1, the internal diameter of overhead gage 2 is more than the internal diameter of blade 1, and outer diameter is preferably less than the outer diameter of blade 1, carries out effective air inducing.Lower block
The back side of plate 3 is fixed with motor (not shown), therefore the circle centre position of lower baffle plate 3 is provided with the axis hole that power supply arbor passes through.
To make lower baffle plate 3 that there is enough intensity, the resonance noise generated when motor operation is avoided, is provided on lower baffle plate 3 multiple
Pressure-type structure, in the present embodiment, pressure-type structure include two kinds, around the first pressure-type structure 5 of axis hole shape annular shape setting
With the second pressure-type structure 6 in the outside of the first pressure-type structure 5 is set, wherein the first pressure-type structure 5 is polygon, the second die mould
Structure 5 surrounds the outside of the first pressure-type structure 5, is arranged in shape radially outward, between adjacent two blade 1, is equipped with one the
Two pressure-type structures 5.
In wind turbine motion process, air inlet region sucking of the wind through 2 inner ring of overhead gage, then by the centrifugal force to run at high speed,
And under the blocking collective effect of the guiding of blade 1 and lower baffle plate 3, be discharged around, direction shown in arrow is that wind is inhaled in Fig. 1
The path enter, being discharged.Overhead gage 2 ensures that the separation in air inlet area and wind outlet area, arc shaped blade 1 can increase total air output, bottom plate
3 prevent the air of discharge from being lost from the bottom of wind turbine, therefore wind turbine provided by the utility model, can be applicable in oven, fixed
On postnotum in oven, to accelerate the thermal cycle speed inside oven, the efficiency of oven baking food is improved, prevents from producing
The dead angle of heat amount aggregation, ensures the quality and flavor of baking food.
