Description
Technical field
This utility model relates to technical field of power generation, particularly a kind of based on bionic wind power generation plant.
Background technology
Though wind-power electricity generation claims clean energy resource, good environmental-protection function can be played, but along with more and more Large Scale Wind Farm Integrations
Setting up, some environmental issues caused by wind-driven generator highlight, and these problems are mainly reflected in noise and to locality life
The impact of state environment.Conventional wind TRT is typically promoted fin to rotate by wind energy, and tip-speed ratio reaches 5～7(levels
Axle wind power generation plant), therefore Existential Space utilization rate is low, wind energy utilization is low, manufacturing cost exponentially increases with fin radius
The problems such as length.(1) tip-speed ratio of horizontal axis wind generating equipment is typically 5～7, will in such high speed lower panel cutting steam
Producing the biggest aerodynamic noise, meanwhile, a lot of birds are difficult to escape by luck under such high speed fin.(2) vertical axis wind power generation
The tip-speed ratio of equipment is typically 1.5～2, and such slow-speed of revolution does not the most produce aerodynamic noise, fullys meet quiet effect
Really.Noiseless has the advantage that it will be apparent that can not apply wind-driven generator because of noise problem before can be applicable to
Occasion (such as urban public utilities, private residence etc.).(3) benefit that low tip-speed ratio brings is not only the advantage of environmental protection, for blower fan
Overall performance be also very favorable.Analyzing from aerodynamic, object speed is the fastest, and the impact of profile stream field is more
Greatly.When wind-driven generator runs out of doors, fin being inevitably contaminated, this pollution actually changes the wing
The profile of sheet.From the point of view of horizontal axis rotor, even if this profile variation is the most small, also greatly reduced the wind energy profit of wind wheel
By rate, and vertical axis rotor is because rotating speed is low, so the change to profile is the most sensitive, the pollution of this fin is the most right
The aeroperformance of wind wheel does not affect.
Being found by research, existing wind power generation plant can be divided into lift-type and two kinds of structures of resistance-type fin, and it is former
Reason is all the rotary motion utilizing fin that wind energy is converted under the effect of air-flow axle.Although these structure technologies existing are relative
The most ripe, but consequent problem is such as: noise is big, big to birds injury, setting height(from bottom) is high, space availability ratio is low etc. always
Can not get solving, the wind power generation plant design structure of the necessary abandoning tradition of these problems will be solved.
Summary of the invention
It is little that the purpose of this utility model is to provide a kind of noise, and space availability ratio and safety are high, and service life is long, manufacture
Low cost and wind energy utilization high based on bionic wind power generation plant.
This utility model is achieved in that it includes base, travelling gear, dividing plate, spring, turn-screw, leaf
Sheet, fixing connecting rod, frame and electromotor, is characterized in that: be provided with travelling gear and turn-screw on base, at turn-screw
On be provided with spring and blade, two corresponding blades are connected by fixing connecting rod, and travelling gear is connected with the axle of electromotor
Connect.
Blade have employed the symmetrical airfoil of NACA type.
The best effort elevation angle of blade is 10 to 15 degree.
The utility model has the advantages that: (1) is quiet；The tip-speed ratio of the design is 1, and the equipment that this ensure that is in work process
Middle wing tip is equal with the linear velocity at wing root, thus avoids aerodynamic noise produced by high-speed motion, fullys meet quiet
Effect, make it application with the transmission wind power generation unconformable occasion of device.(2) space availability ratio is high；With traditional wind
Power generation device is compared, and the space shared by this device is smaller, and can improve in the way of using the combination of townhouse solid
Space availability ratio.(3) safety is high；This product does not has the rotating vanes of major diameter, for conventional wind TRT
Safety is higher, can be prevented effectively from and be damaged flying birds.(4) service life is long；Send out based on bionic wind-force
The overall movement speed of electric installation fin is relatively low, and suffered inertia force is with gravity in one direction, so that fin is from it
Moment of torsion effect on its direction, enhances the fatigue strength of fin, reduces the use cost of fin.(5) low cost of manufacture；Pass
The fin manufacturing cost of system wind power generation plant is that 3 powers increase along with the growth of finned length and fin radius, and blower fan
Wind sweeping area becomes positive correlation with the output of blower fan, say, that the output of blower fan is 2 times with the growth of fin radius
Side's relation, this speed allowing for the growth of fin manufacturing cost is far longer than the rate of rise of output, when fin radius surpasses
After crossing certain length, along with the increase of finned length, cost of investment sharp increase, and output increases slower, it will reach
To limits to growth, there is the limitation of use, and the increase of this design finned length is linear with manufacturing cost, therefore has
There are the potentiality of exploitation same model great wind-power units.Meanwhile, the design process of equipment have employed standard component in a large number
Use such as: cone bearing, freewheel clutch etc., reduce the manufacturing cost of equipment, also reduce the use of post facility simultaneously
And maintenance cost.(6) wind energy utilization is high；It is known that power in the movement direction time work efficiency the highest, and for symmetry
For the fin of aerofoil profile, keep the suitable elevation angle (100~150) maximum lift can be obtained.And traditional lift-type wind-power electricity generation
Among the elevation angle of device fin and relative wind is always at being continually changing, fin can not be always maintained at the work of the optimal elevation angle.Cause
Wind energy can not be maximally utilized by this, and utilization rate is difficult to improve.And we work based on bionic wind power generation plant fin
Time always remain at 130The optimal elevation angle on, fin total energy obtains maximum lift.

Detailed description of the invention
As shown in Figure 1, 2, 3, base 1, travelling gear 2, dividing plate 3, bullet should be included based on bionic wind power generation plant
Spring 4, turn-screw 5, blade 6, fixing connecting rod 7, frame 8 and electromotor 9, be provided with travelling gear 2 and driving wire on base 1
Thick stick 5, is provided with spring 4 and blade 6 on turn-screw 5, and two corresponding blades 6 are connected by fixing connecting rod 7, driving cog
Wheel 2 is connected with the axle of electromotor 9.Blade 6 have employed the symmetrical airfoil of NACA type, and the best effort elevation angle of blade 6 is 10
To 15 degree.
Operation principle:
When lower blade 6 does upstroke, left side turn-screw 5 is driven and is rotated in the clockwise direction, right side transmission
Leading screw 5 is driven, but owing to the screw thread spin line of two turn-screws 5 is mirrored symmetry along centrage.Therefore, right side turn-screw
5 rotation directions are contrary with left side turn-screw 5 rotation direction, in rotating counterclockwise.Owing to drivewheel A, B centre of gyration is equipped with super
More clutch, all only along being driven clockwise.So, when lower blade 6 does upstroke, only drivewheel A quilt
Driving and drive driven pulley C to rotate, driven pulley C drives electrical power generators again.
When blade 6 does downward movement, owing to two turn-screws 5 are mirrored symmetry, turn-screw 5 for axis
Upper and lower two-part screw thread spin line is reverse, therefore, also drives left side turn-screw 5 to do clockwise when blade 6 does downward movement
Rotating, when action effect does upstroke with lower blade 6, action effect is consistent, and drivewheel A is driven, and drivewheel B is not driven.
When upper and lower blade 6 moves to axis simultaneously, the output of blade 6 is delivered to drivewheel along left side leading screw
A, drives driven pulley C to drive the external output of electrical power generators the most again；When upper and lower blade 6 is simultaneously to two end motions, with
Contrast when upper and lower blade 6 moves to axis, blade 6 makees turn-screw 5 on the right side of downward movement driving and does dextrorotation
Turning, left side turn-screw 5 does rotation counterclockwise, and now, right side turn-screw 5 drives drivewheel B to drive driven pulley C to drive generating
Machine generating output, the output of blade 6 is delivered to electromotor 9 by right side turn-screw 5 and exports, left side turn-screw
5 rotate counterclockwise, not output.
