Form Karman vortex street.When object two sides generate periodic vortex, since Vortex Shedding alternately falls off, then object is lateral
Two sides can generate pressure difference.Under pressure action, object will receive a cross force, as whirlpool induced lift force, because of object two sides
The vortex of generation is presented periodically, then periodicity can be also presented in whirlpool induced lift force, when the frequency of whirlpool induced lift force and the intrinsic frequency of system
When rate is close, object will generate violent shake.
On-bladed wind energy conversion system is a kind of a kind of device to be generated electricity based on Karman vortex street theory.When wind acts on wind tower
When, wind can generate whirlpool induced lift force to wind tower, and when the frequency of whirlpool induced lift force is close with the intrinsic frequency of wind tower, wind tower will be produced
The vibration of raw certain frequency, to drive the movement of the mover of generator in the stator to realize that magnetic force line cutting carries out by connecting rod
Power generation.
The wind tower of on-bladed wind energy conversion system is connected by globular hinge with the mover of generator, wherein connect with globular hinge
Bar can only deflect, i.e., wind tower can deflect under wind action, and when wind acts on wind tower, wind tower can be sent out along wind direction
Raw inclination, wind machine device generating efficiency in this case will reduce, or even cannot generate electricity；On the other hand, wind tower is in wind
Due to the superposition of amplitude under power effect, eventually leads to structure caused by entire wind machine device reaches capacity because of dynamic stress and destroy.
Summary of the invention
It is an object of the invention to the resets and amplitude superposition for wind tower existing in the prior art under the action of the wind

Higher hollow metallic rod；1 upper end of wind tower support rod is connected with the wind tower of on-bladed wind energy conversion system, lower end by globular hinge 5 with
Generator is connected, and when wind tower is acted on by wind-force, wind tower support rod 1 can deflect around globular hinge 5 without around wind tower
The longitudinal axis rotation of support rod 1 itself, so that the wind tower being connected with wind tower support rod 1 is subjected to the effect of any wind direction；Wind
The middle part of tower support rod 1 is fixed with moving magnet 2；It is equipped with cylinder 11 in the periphery of wind tower support rod 1, wind tower support rod 1 does not occur
Center axis thereof is overlapped with the central axis of cylinder 11 when deflection；In 11 inside of cylinder, the position opposite with moving magnet 2 is fixed with
Fixed magnet 10, the lateral surface of moving magnet 2 is identical with the magnetic pole of the inside portion of fixed magnet 10, has between moving magnet 2 and fixed magnet 10
There is certain spacing, the medium in spacing is air；The deflection of wind tower support rod 1 can make between moving magnet 2 and fixed magnet 10
Distance changes, and based on the principle of magnetic field homopolar-repulsion, can generate the magnetic force to repel each other between the two, generated mutual expelling force is compeled
It moves wind tower support rod 1 round about, to realize the reset of wind tower support rod 1, while also just solving wind tower support rod 1
Amplitude when resonating is superimposed problem；To make the magnet of unit area generate bigger magnetic force, moving magnet 2 and fixed magnet 10
It is all made of the ndfeb magnet of radial magnetizing, is circle tube member；It is located on fixed magnet 10 on the inside of cylinder 11 and is fixed with
Tilt controller 7.
In conjunction with Fig. 4, moving magnet 2 by be mounted thereon, the moving magnet fixator 3 at lower both ends is fixed on wind tower support rod 1
On.As seen from Figure 4, moving magnet fixator 3 is the circle tube member for having circular ring shape bottom edge, circular ring shape bottom edge and dynamic magnetic
The end of iron 2 offsets, and is set on stack shell there are two opposite pin hole, by passing through two opposite pin holes and wind tower support rod 1
Moving magnet 2 is fixed on wind tower support rod 1 by the straight pin 4 of upper pin hole.
In conjunction with Fig. 6, cylinder 11 is a columnar component, from Fig. 1 to Fig. 3 as it can be seen that 11 medial surface bottom of cylinder is equipped with
One round ring boss, fixed magnet 10 can be rest directly upon on the round ring boss, while to make resetting apparatus of the present invention work
Guarantee the stability of system in the process, the internal diameter of cylinder 11 is equal with the outer diameter of fixed magnet 10.In conjunction with Fig. 5, tilt controller 7 is
One circle tube member with circular ring shape top surface and hollow out bottom surface and intermediate medial surface for back taper anchor ring, tilt controller
7 outer diameter with 11 internal diameter of cylinder is mating is placed in cylinder 11, from Fig. 5, Fig. 6 as it can be seen that on the circular ring shape top surface of tilt controller 7
Four bolts hole corresponding with 11 top surface bolt hole of cylinder are evenly arranged, such tilt controller 7 can be solid by screw 8
It is scheduled on cylinder 11；Gasket 9 is equipped between 7 bottom surface of 10 top surface of fixed magnet and tilt controller, tilt controller 7 passes through gasket 9
Fixed magnet 10 is compressed, so that tilt controller 7, gasket 9, fixed magnet 10 and cylinder 11 be made to be connected to become an entirety.From Fig. 1 to

Shield effect.
The course of work of cylinder-shaped magnetic force resetting device for on-bladed wind energy conversion system of the invention is as follows:
Referring to Fig. 1 to Fig. 3, when the wind met certain condition bypasses the wind tower being connected to above the device, wind tower two sides
Periodically falling off, direction of rotation out is opposite, biserial whirlpool of queueing discipline forms karman vortex after nonlinear interaction
Street.After Karman vortex street appearance, wind can generate the alternation cross force of a cycle, i.e. whirlpool induced lift force to wind tower, when whirlpool commendable increase
When the frequency of power and the close intrinsic frequency of wind tower, it will cause wind tower to generate resonance, wind tower and wind tower support rod 1 can be around at this time
Deflection perpendicular to wind direction occurs for globular hinge 5；Moving magnet 2 moving magnet 2 and determines magnetic when deflecting with wind tower support rod 1
Distance of the iron 10 along deflection direction will reduce, since the average distance between the magnetic force and magnetic pole between two permanent magnets is inversely proportional
And moving magnet 2 is identical as the magnetic pole of 10 opposite face of fixed magnet, thus can be generated between fixed magnet 10 and moving magnet 2 one with partially
Turn contrary magnetic force, force wind tower support rod 1 back to equilbrium position, is i.e. at position O, and class this circulation is gone down.
When wind tower is in resonance process, wind tower support rod 1 deflects into position R, i.e. wind tower support rod from position O with wind tower
1 deflects to the right α angle around globular hinge 5, as shown in Figure 1, the opposing magnetic force between two magnet reaches maximum, and forces wind tower branch
Strut 1 returns to position O from position R, as shown in Figure 2；When wind tower support rod 1 deflects into position L from position O, i.e. wind tower branch
Strut 1 deflects α angle around globular hinge 5 to the left, as shown in figure 3, return in place from position L under opposing magnetic force effect later again
Set O.Since the magnetic pole of opposite face between moving magnet 2 and fixed magnet 10 is identical, the opposing magnetic force on the one hand generated between two magnet,
The centre of oscillation of the wind tower support rod 1 when resonating with wind tower can be made to be always positioned in when wind tower support rod 1 does not deflect
At mandrel line position O；On the other hand when wind tower generates resonance under the action of the wind, it can make wind tower in safe amplitude range
Resonance, without making wind tower lead to the superposition of amplitude under the effect of sustained wind power, so that wind machine device be avoided to reach because of dynamic stress
Structure is caused to destroy to the limit.
