Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiments belong to protection scope of the present invention.
As shown, a kind of liter hinders composite vertical axis wind generator, comprising: blade 30, blade 31, central fixed shaft
10, rotary sleeve 20, rotating frame 21, speed increasing gear 14, cable wire fixed disk 12, cable wire 13, fixing axle guiding rudder 11.
Resistance-type vertical axis wind turbine, crosswind leaf does positive work with the wind, and contrary wind crosswind leaf does negative work, so its air-flow utilization rate
It is very low.Lift-type wind energy conversion system generates the principle of lift according to aircraft wing, utilizes the fan blade liter that high-speed cruising generates in air
Power acting, positive work is all done in side and contrary wind side with the wind.But most of lift-type wind energy conversion systems, wing is not the wing of aircraft, and
It is symmetrical streamlined wing.This is because the fan blade that fixed aircraft wing is wing, in rotary course, if
Fourth quadrant is that the left right side of putting down is convex, generates lifting force moment and is positive, then being also that the left flat right side is convex in first quartile, generation lifting force moment is
It is negative.It is that the left convex right side is flat in the second quadrant, generates lifting force moment and be positive, is that the left convex right side is flat in third quadrant, generating lifting force moment is
It is negative.It is positive and negative to offset, so, asymmetrical aircraft wing is wing, can not bring positive torque herein.Using fairshaped right
Claim wing, resistance can be effectively reduced, while equally can produce lift using the wing angle of attack.Liter resistance proposed by the present invention is multiple
Mould assembly vertical axis aerogenerator, since its is wing variable, in working condition, not only attack angle of blade all four quadrants all
Positive turning moment is generated, wing plano-convex changes the turning moment that generated lifting force moment is also all positive, so its
Efficiency is higher.
As shown in Fig. 2, a kind of liter hinders composite vertical axis wind generator, and the course of work is such that in air-flow
Under promotion, blade 30 and 31 on rotating frame 21 rotates counterclockwise, blade 30 and 31 on the left of central fixed shaft 0 o'clock to 9
When o'clock runs, blade 30 and 31 brings into operation from plumbness, at this point, under the top edge of blade 30 and 31 linear velocity is greater than
Edge linear velocity, blade 30 and 31 generate right-handed moment.Airflow direction vertically upward, in the up time of blade 30 and 31
Needle rotates by a certain angle, and after the leading edge of blade 30 and 31 is tilted to the left, air-flow will generate counterclockwise rotating force square to blade 30 and 31.
After positive and negative equalising torque, blade 30 and 31 and airflow direction keeping parallelism, at this point, uprush is to blade 30 and 31 without rotatory force
Square rotates the thrust of the blade 30 and 31 pair air of generation, and because blade 30 and 31 is vertical with horizontal direction, level run is fast to the left
Identical about degree, blade 30 and 31 is symmetrical above and below, therefore the suffered thrust to the right of about 31 blade 30 and is equal, also produces without torque
It is raw.So blade 30 and 31 and airflow direction keeping parallelism are stable states.Because blade is deviateed on the vertex of eccentric cam 23 at this time
30 and 31 center, will generate thrust to the left panel of blade 30 and 31 33, which generates the power rotated clockwise
Square, this torque make the leading edge of blade 30 and 31 deviation vertical line slightly incline to the left.Withstand a left side for coaming plate 33 in the vertex of eccentric cam 23
Side, so that 33 left hand projection of coaming plate, right side is horizontal, and the angle of attack and blade 30 and 31 that airflow direction slightly inclines to the left to this are left
The flat wing effect in the convex right side, the aircraft wing for complying fully with standard generate the principle of lift.Generated lift to the left, torque
For forward torque counterclockwise.
When 9 o'clock to 6 o'clock runs on the left of central fixed shaft, blade 30 and 31 brings into operation blade from plumbness,
At this point, 23 vertex of eccentric cam starts the right side for being biased to blade 30 and 31, with the increasing of rotation angle, the top of eccentric cam 23
Point will be gradually increased to the jack-up dynamics on the right side of coaming plate 33, and 33 profile of coaming plate becomes left flat right convex.It is run with 0 point to 9 section
Principle is identical, 9 points to 6 sections, and blade 30 and 31 will keep blade inlet edge and vertical direction slightly to run to the angle of right avertence.
Operation is to 6 o'clock position, because 10 right side outside diameter of central fixed shaft is greater than left side outside diameter, blade 30 and 31
The wheel that rotates against 37 the right side outer circle with central fixed shaft 10 is leant, hereafter, blade 30 and 31 when rotated, due to leaf
The inward flange linear velocity of piece 30 and 31 is less than outer edge linear velocity, and air-flow is pushed away to what the inside of blade 30 and 31 generated
Power is greater than the thrust generated to outside, and blade generates the torque rotated clockwise, and rotates clockwise by central fixed shaft 10
To the obstruction for rotating against wheel 37, so, the blade face of blade 30 and 31 will be run to always with 22 keeping parallelism of rotating frame boom
0 o'clock position, during which, blade 30 and 31 is flat right convex to a 3 o'clock position left side at 6 o'clock, and lifting force moment is positive torque counterclockwise,
Blade 30 and 31 is left convex right flat in 3 o'clock to 0 o'clock position, and lifting force moment is also positive torque counterclockwise.
When due to generator operation, 21 rotation speed of rotating frame is very low, when air-flow vertically blows to fan blade, right side resistance-type wind
Leaf will generate obstruction to air-flow, and the guiding of right side blade will force on the left of air flow direction, in this way, the gas flowed through due to the unit time
Body flow increases, and the air velocity at 9 o'clock of left side to 12 o'clock position certainly will increase, and airflow direction can deflection to the left.This
The air-flow that a deflection to the left and speed become larger will generate thrust to the left to row to blade herein, increase forward direction counterclockwise
Torque.
During whole service, the wing and angle of attack of impact of the air-flow to blade 30 and 31, blade 30 and 31 all meets
The theory of airfoil lift, the torque that lift generates is entirely forward torque.Positive lift torque, not only in central fixed shaft
10 left sides generate, and equally can also generate on 10 right side of central fixed shaft.These positive lift torques, in addition central fixed shaft 10
The resistance-type torque on right side, it is common that runner is pushed to rotate counterclockwise, drive electrical power generators.Therefore, the vertical axis runner is practical
On be lift, a resistance mixed vertical axis.Its operation on the right side of central fixed shaft 10, in addition to resistance is done
Except positive work, lift is also doing positive work simultaneously, the operation in 10 left side of central fixed shaft, in addition to the resistance of very little part does negative work
Except, bigger lift is all doing positive work, high-efficient, lift-type blower high speed rotation when due to, resistance-type blower low speed rotation
When it is high-efficient, therefore, come to control the tip speed ratio of runner rationally by adjusting the no-load voltage ratio of generator loading and speed change system, can be with
Reach the maximum power generation efficiency of wind energy conversion system.Although not accurately calculating and testing test, tentatively calculate that this vertical-shaft wind is sent out
The wind energy utilization of motor will be considerably beyond 50%, and conservative estimation is not less than 70%.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
