Specific embodiment
As Figure 1-3, this utility model only taking four fan blades 3 as a example.Including the power under the center chain wheel 10 on top
Square output shaft 1, be connected with by connecting rod 2 has the airplane wing-shaped fan blade 3 of upper end cover 4 and bottom end cover 5 in interior air operated machine main body, its
It is characterised by also including one piece of upper and lower square having rotating shaft 13 being located between fan blade 3 rear portion, upper end cover 4 and bottom end cover 5
Shape plate 6, and it is provided with a gravity rod 7 in this rectangular slab 6 near fan blade 3 side level, and respectively in the tail of upper end cover 4, bottom end cover 5
Portion is provided with the bearing 12 of fixed rotating shaft 13, and upper rotating shaft 13 is connected with the wind spring stud 14 of upper end cover 4 afterbody via wind spring 11, and
And be fixed with chain wheel 8 on the top of upper rotating shaft 13, the chain wheel 8 in rotating shaft 13 by a ring chain being consistent with chain wheel 89 with
Heart chain wheel 10 associates, and with the self adaptation efficiency to wind speed for each fan blade 3 of the unified air operated machine main body that keeps linking, realizes air operated machine
Easily start when wind speed is low, when wind speed is high, rotating speed does not transfinite, and remain at good dynamic equilibrium state.
As shown in figure 1, the fan blade number of above-mentioned air operated machine is generally according to the requirement to air operated machine output torque, local year
The combined factors such as the situation of mean wind speed, the setting of air operated machine rated speed consider to determine.Such as require air operated machine output big
During the moment slow-speed of revolution, generally in the form of more than 6 multiple fan blades.To the air operated machine for generating electricity it is desirable to wind energy conversion is imitated
Rate is high, and cost performance is high, generally adopts the high rotating speed form of 5-3 following fan blade.
This utility model associates because the chain wheel 8 in rotating shaft 13 is all fastened with center chain wheel 10 by ring chain 9, thus
The inflection point of rectangular slab 6 at each fan blade 3 rear portion and deflection angle all remain the unified state linking, and prevent air operated machine from existing
Produce vibration when running up because of disequilibrium and cause to damage.
The width of above-mentioned rectangular slab 6 is a quarter of fan blade 3 width to 1/3rd.It is higher for annual mean wind speed,
When rated speed requires higher, rectangular slab is narrowlyer optional；Relatively low for local wind speed, when rated speed requires relatively low, square
Shape plate is optionally wider.
Above-mentioned gravity rod 7 length is equal with the width of rectangular slab 6.
Above-mentioned gravity rod and rectangular slab are integrative-structures, and are in approximately the same plane when static.
As shown in Fig. 2 a quarter that the width of above-mentioned rectangular slab 6 is fan blade 3 width is according to wind pair to 1/3rd
The rated speed that motivation sets to determine with combined factors considerations such as local wind behaviours.
The size of the rotary inertia of above-mentioned gravity rod 7 countershaft 13 is to be determined according to the rated speed that air operated machine sets
's.When wind speed remains static for " 0 " air operated machine, gravity rod 7 leans against the inner side of fan blade upper surface, and rectangular slab 6 is in aerofoil profile
On the extension equilbrium position of the upper surface of fan blade 3.When wind speed is gradually increased, the moment of gravity rod 7 centrifugal force is also with increase.Volume
The moment of elasticity of spring 11 is in opposite direction with the moment of gravity rod centrifugal force.When the rotating speed of air operated machine is less than the rotating speed of volume, gravity
The moment of bar 7 centrifugal force is less than the reverse elasticity moment of wind spring 11, and gravity rod 7 and rectangular slab 6 do not rotate, still in former
The poised state come, rectangular slab 6 is equivalent to the broadening of fan blade 3 upper surface, thus increase fan blade 3 the forward drive moment of resistance and
Lifting moment, makes air operated machine in low wind speeds it is easier to start.
As shown in figure 3, the rotating speed of air operated machine quickly increases with the increase of wind speed, when wind speed is equal to or higher than rated wind speed
When, air operated machine rotating speed is equal to or higher than rated speed, and (the centrifugal force size of gravity rod 7 and rotating speed square be directly proportional) now weighs
The moment of the centrifugal force of power bar 7 is just more than the reverse elasticity moment of wind spring 11, and this difference moment just drives gravity rod 7 to drive rectangle
Plate 6 leaves equilbrium position and 13 produces rotation around the shaft, makes it be no longer on the extended position of the upper surface of fan blade 3, but leaves
And intersect at an angle, the air force state of therefore aerofoil profile fan blade 3 is destroyed, lift cancellation, and reverse resistance increases,
Air operated machine rotating speed is caused to decline immediately, when rotating speed is less than rated speed, the centrifugal force moment of gravity rod 7 is less than wind spring 11
During opposing torque, this opposing torque forces gravity rod 7 and rectangular slab 6 to be turned back to original equilbrium position again.So just effective
Prevent in the environment of high wind speed, air operated machine rotating speed exceedes rated speed and causes to damage.
Therefore, this utility model when air operated machine is in calm static when, due to wind spring 11 bounce effect, rectangular slab 6
Gravity rod 7 lean against on aerofoil profile fan blade 3, rectangular slab 6 is connected with fan blade upper surface, make fan blade formed a complete wing
Type；When wind speed gradually steps up, the aerofoil profile fan blade 3 being in diverse location produces driving resistance and lift, and air operated machine is driving resistance
Start rapidly under the common driving of square and lifting moment, rotating speed is gradually increased, gravity rod 7 is because by centrifugal action, countershaft 13 produces
The life moment contrary with wind spring 11, square being directly proportional of the size of this moment and rotating speed.When air operated machine rotating speed is less than rated speed
When, the moment that gravity rod 7 centrifugal force produces is less than the opposing torque of wind spring 11, and gravity rod 7 still leans against on blade, the work of rectangular slab
With being equivalent to the width broadening of fan blade, so that the driving moment of resistance of fan blade and lift is increased, thus so that air operated machine is held in low wind speed
Easily start；When wind speed continues to raise, air operated machine rotating speed increases sharply, and speedup is directly proportional to wind speed cube.When rotating speed is close
Or when exceeding rated speed, the moment that on each fan blade, the centrifugal force of gravity rod 7 is formed is more than the opposing torque of wind spring 11, gravity
Bar 7 will drive upper rectangular slab 6 to rotate, and with the upper surface shape of aerofoil profile fan blade 3 in an angle, immediately change airfoil type fan blade
3 air force state, lift reduces, and reverse resistance increases, and so that air operated machine driving moment is reduced, rotating speed reduces, until gravity
The moment of bar 7 centrifugal force is less than the opposing torque of wind spring 11, till rectangular slab 6 rotates back into original equilbrium position.Now due to
Chain wheel 8 on the rectangular slab 6 of each fan blade 3 by ring chain 9 associate integral so that the rectangular slab 6 of each fan blade 3 and fan blade
The angle that 3 upper surfaces are formed is always consistent, it is to avoid rectangular slab 6 deflection angle of each fan blade 3 is different and the wind that produces
Motivation unitary rotation disequilibrium and produce vibration cause damage problem.
This utility model is provided with, at the rear portion of each fan blade 3 of air operated machine, the rectangular slab 6 being equivalent to upper surface extension, and each
The deflection of the rectangular slab that the upper surface of fan blade 3 extends is connected by chain wheel 8 and chain 9 again and unifies linkage, so that air operated machine
Wind energy conversion performance get a promotion：Driving force is lifted, air operated machine easily starts when wind speed is low；When wind speed meet or exceed specified
Driving moment can be reduced, the increase of suppression rotating speed, it is to avoid cause air operated machine to damage because rotating speed exceedes rated speed during wind speed
Bad.The vibration causing because of disequilibrium when simultaneously again preventing air operated machine operating and damage.Thus it is excellent to be built into stable performance
