Wherein, 1 moment output shaft, 2 connecting rods, 3 fan blades, 4 upper end covers, 5 bottom end covers, 6 rectangular slabs, 7 gravity rods, 8 chain wheels, 9 chains, 10 center chain wheels, 11 wind springs, 12 bearings, 13 rotating shafts, 14 wind spring studs.
Detailed description of the invention
As Figure 1-3, the present invention is only as a example by four fan blades 3.Defeated including the moment under the center chain wheel 10 on top 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 feature It is also to include a upper and lower rectangular slab having rotating shaft 13 of a piece be located between fan blade 3 rear portion, upper end cover 4 and bottom end cover 5 6, and it is provided with a gravity rod 7 at this rectangular slab 6 near fan blade 3 side level, the afterbody at upper end cover 4, bottom end cover 5 sets the most respectively The bearing 12 of fixed rotating shaft 13, upper rotating shaft 13 is had to be connected via the wind spring stud 14 of wind spring 11 with upper end cover 4 afterbody, and The top of upper rotating shaft 13 is fixed with chain wheel 8, and the chain wheel 8 in rotating shaft 13 is by a ring chain being consistent with chain wheel 89 and center tooth Dish 10 associates, to keep linkage to unify each fan blade 3 of air operated machine main body the self adaptation usefulness to wind speed, it is achieved air operated machine is at wind Speed easily starts time low, and during wind speed height, rotating speed does not transfinites, and remains at good dynamic equilibrium state.
As it is shown in figure 1, the fan blade number of above-mentioned air operated machine is generally according to the requirement of air operated machine output torque, local year The situation of mean wind speed, the combined factors such as setting of air operated machine rated speed consider to determine.Such as require that air operated machine output is big During the moment slow-speed of revolution, generally use the form of more than 6 multiple fan blades.To the air operated machine for generating, it is desirable to wind energy conversion effect Rate is high, and cost performance is high, generally uses the high rotating speed form of 5-3 following fan blade.
Due to the fact that the chain wheel 8 in rotating shaft 13 is all fastened with center chain wheel 10 by ring chain 9 to associate, thus each The inflection point of the rectangular slab 6 at fan blade 3 rear portion and deflection angle all remain the state of unified linkage, prevent air operated machine at a high speed Produce vibration during operating because of disequilibrium and cause damage.
The width of above-mentioned rectangular slab 6 is 1st/to three/4th of fan blade 3 width.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 the most 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 time static.
As in figure 2 it is shown, the width of above-mentioned rectangular slab 6 is 1st/to three/4th of fan blade 3 width is according to wind pair The combined factors considerations such as the rated speed of motivation setting and local wind behaviour determine.
The size of the rotary inertia of above-mentioned gravity rod 7 countershaft 13 is that the rated speed set according to air operated machine determines '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 it is shown on 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 Time, air operated machine rotating speed equals 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, therefore the air force state of aerofoil profile fan blade 3 is destroyed, lift cancellation, reverse resistance increase, Causing air operated machine rotating speed to decline immediately, during until 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 again original equilbrium position.The most effective Preventing in the environment of high wind speed, air operated machine rotating speed exceedes rated speed and causes damage.
Therefore, the present invention when air operated machine is in calm static time, due to the bounce effect of wind spring 11, the weight of rectangular slab 6 Power bar 7 leans against on aerofoil profile fan blade 3, and rectangular slab 6 is connected with fan blade upper surface, makes fan blade form a complete airfoil type; When wind speed gradually steps up, be in the aerofoil profile fan blade 3 of diverse location and produce and drive resistance and lift, air operated machine drive the moment of resistance and Lifting moment common drives and lower starts rapidly, and rotating speed is gradually increased, gravity rod 7 because of by centrifugal action, countershaft 13 produce with The moment that wind spring 11 is contrary, square being directly proportional of the size of this moment and rotating speed.When air operated machine rotating speed is less than rated speed, weight The moment that power bar 7 centrifugal force produces is less than the opposing torque of wind spring 11, and gravity rod 7 still leans against on blade, the effect phase of rectangular slab When in the width broadening of fan blade, making the driving moment of resistance of fan blade and lift increase, thus make air operated machine easily open in low wind speed Dynamic;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 super When crossing 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 rod 7 Rectangular slab in drive 6 is rotated, and with the upper surface shape of aerofoil profile fan blade 3 in an angle, immediately changes airfoil type fan blade 3 Air force state, lift reduces, and reverse resistance increases, and makes air operated machine driving moment reduce, and rotating speed reduces, until gravity rod 7 The moment of 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 each Chain wheel 8 on the rectangular slab 6 of fan blade 3 is associated to one by ring chain 9 so that on the rectangular slab 6 of each fan blade 3 and fan blade 3 The angle that surface is formed is always consistent, it is to avoid rectangular slab 6 deflection angle of each fan blade 3 is different and the air operated machine that produces Unitary rotation disequilibrium and produce vibration cause damage problem.
The present invention is provided with at the rear portion of each fan blade 3 of air operated machine and is equivalent to the rectangular slab 6 that upper surface extends, and each fan blade The deflection of the rectangular slab that the upper surface of 3 extends is connected by chain wheel 8 and chain 9 again and unifies linkage, so that the wind of air operated machine Can conversion performance get a promotion: promoting driving force when wind speed is low, air operated machine easily starts;When wind speed meets or exceeds rated wind speed Time can reduce driving moment, the increase of suppression rotating speed, it is to avoid cause air operated machine to damage because rotating speed exceedes rated speed.With Time prevent again the vibration and damage that air operated machine causes when operating because of disequilibrium.Thus it is built into the wind that stable performance is excellent Motivation.
