Embodiment
In order to more fully understand technology contents of the present utility model, with reference to schematic diagram to technical side of the present utility model
Case is further described and illustrated, but is not limited to this.
As shown in figure 1, a kind of generator 10 using asymmetric two-way empennage, including, fan blade 1, Wind turbines 2 are used for
The support 3 of Wind turbines 2 is installed, the afterbody of Wind turbines 2 and pair for adjusting the first reference plane and windward side angle is fixed on
To empennage 4, wherein, Wind turbines 2 are rotated with support 3 and are connected.
The vertical plane of Wind turbines 2 fan blade, 1 rotary shaft is the first reference plane, the rotary shaft of fan blade 1 and machine of Wind turbines 2
Rotary shaft the second reference plane of formation of cabin 21.
The rotary shaft of cabin 21 of Wind turbines 2 is inclined upwardly, and fan blade 1 is tilted to the side of the first reference plane.In this implementation
In example, windward side is right against, the upper end of right side fan blade is tilted to the front side of the first reference plane, the upper end of left side fan blade is to the first base
The rear side in quasi- face is tilted.
The elevation angle of the rotary shaft of cabin 21 of Wind turbines 2 is θ, and θ scope is 5 ° -45 °.
The quantity of fan blade 1 is 2, the upper end of right side fan blade 1 to the front side angle of inclination of the first reference plane be ω, ω model
Enclose for 0-45 °.
As shown in Fig. 2 asymmetric two-way empennage 4 includes left wing plate 41, right wing plate 42.The reference plane of left wing plate 41 and second
Angle is σ, and the angle of the reference plane of right wing plate 42 and second is β, and σ scope is 10 ° -30 °, and β scope is 5 ° -20 °, and β is less than
σ, σ-β scope are 5 ° -25 °.
Asymmetric two-way empennage 4 also includes fixture 43, is respectively arranged on the right company between right wing plate 42 and fixture 43
Fitting 44, the left connector 45 between left wing plate 41 and fixture 43.Left wing plate 41, right wing plate 42 are split-type structural,
Both are individually fixed in the both sides of fixture 43, wherein, fixture 43 is fixed on the afterbody of Wind turbines 2.Right wing plate 42 is with consolidating
Support can be played a part of, so as to ensure right wing plate when right wing plate 42 is by wind-force by determining the right connector 44 between part 43
42 and the second angle between reference plane fix.
When Wind turbines 2 generate electricity, because the elevation angle of the rotary shaft of cabin 21 is θ, and fan blade 1 inclines on front side of the first reference plane
Rake angle is ω, therefore, when 2 fan blades 1 are all in horizontal level, and right side fan blade 1 and the angle of windward side are ω-θ, and left
The angle of crosswind leaf 1 and windward side is θ+ω, and therefore, the wind area of right side fan blade 1 and left side fan blade 1 is different, by than
Compared with it is recognised that the actual wind area of right side fan blade 1 is greater than the wind area of left side fan blade 1, therefore produce in the horizontal direction
A raw clockwise moment of torsion, while can also form a torque in the plane perpendicular to the rotary shaft of cabin 21, during startup, only
Need smaller wind-force just can be so that Wind turbines 2 are generated electricity, in actual tests, the threshold wind velocity of Wind turbines 2 is
0.8m/s.And be connected because Wind turbines 2 and support 3 are rotated, therefore, Wind turbines 2 can also rotate in the presence of torque, and
Wind turbines 2 and the angle of windward side then determine generating efficiency, and following table is that Wind turbines 2 are imitated with windward side deflection angle to generating electricity
The influence of rate：
| Deflection angle | Generating efficiency |
| 10° | Reduction by 10% |
| 20° | Reduction by 40% |
| 30° | Reduction by 80% |
| 40° | 0 |
From the foregoing, it will be observed that influence of the size of Wind turbines 2 and windward side angle to generating efficiency is very big, and use inclined shaft
Wind turbines 2 and the deflection angle of fan blade 1, although can solve the problem of threshold wind velocity is low, reduction generating efficiency can be brought when simultaneously
The problem of.
It is specific with θ=30 °, ω=30 °, σ=20 ° are illustrated exemplified by β=10 °, when 2 fan blades 1 are all in level
During position, the angle of right side fan blade 1 and windward side is ω-θ=0 °, and left side fan blade 1 and the angle of windward side be θ+ω=
60 °, therefore, actual wind area and the fan blade area ratio of right side fan blade and windward side are 1, the reality of left side fan blade and windward side
Wind area is 0.5 with fan blade area ratio, and therefore, generating set has a clockwise torque.And port tailplane and the second base
The angle in quasi- face is big, and in the case where left and right fin area is suitable, the wind area of port tailplane is also bigger than starboard tailplane, now, meeting
Torque counterclockwise is produced, the torque can be used for offsetting the torque suffered by fan blade, so that fan blade is right against windward side,
To improve generating efficiency.σ=20 °, β=10 °, when starboard tailplane turn clockwise 10 ° when, σ becomes 30 °, and β becomes 0 °, relative to
Single empennage rotates 10 °, and its starboard tailplane only has 10 ° of deflection angle, therefore, using the correction effect produced by asymmetric empennage than single
Empennage will get well.
In other embodiments, left wing plate and right wing plate are integral type structure, and two-way empennage also includes fixture, right wing plate
The afterbody of fixture is fixed on left wing plate, fixture is fixed on the afterbody of Wind turbines.
In other embodiments, the quantity of fan blade can be 3 or 4.
In other embodiments, windward side is right against, the front end of right side fan blade is tilted to the rear side of the first reference plane, left side
The front end of fan blade is tilted to the front side of the first reference plane, and the angle of right wing plate and the second reference plane is σ, left wing plate and the second benchmark
The angle in face is β, and σ scope is 10 ° -30 °, and β scope is 5 ° -20 °, and σ-β scope is 5 ° -25 °, and the structure of fan blade is with before
Fan blade is stated towards on the contrary, the angle between the second reference plane of empennage is also opposite.
It is above-mentioned that technology contents of the present utility model are only further illustrated with embodiment, in order to which reader is easier to understand,
But embodiment of the present utility model is not represented and is only limitted to this, and any technology done according to the utility model extends or recreated,
