Center of gravity, enhancing swing effect, be convenient for collection of energy.
Design principle of the invention are as follows: when the present invention is static, be in its equilbrium position, upper magnet yoke 5 is with lower yoke 4 due to each
From the effect of the upper permanent magnet 6 and lower permanent magnet 3 that are connected, form repulsion, the repulsion balance device top upper magnet yoke 5,
The gravity of upper permanent magnet 6 and pendulum 7, and upper magnet yoke 5 is equal with the interval of four lower yokes 4.In extraneous vibration, perturbation action
Under, the relative position of the substructure of the superstructure and device of device changes, and rotates or moves, due to upper magnetic
Yoke 5 is closer to lower yoke 4, this relative motion forms two sides vertical with the circular conical surface axis of upper magnet yoke 5 based on rotating
Upward swing.Under swing effect, so that the interval variation between upper magnet yoke 5 and four lower yokes 4, is spaced at increase, reprimand
Power decline；Be spaced at reduction, repulsion rises, formed with its torque that deviate equilbrium position opposite, make its deceleration of motion, and then make
Its rotation that opposite direction occurs is formed and is swung.Due to it is close to each other between High-coercivity Permanent Magnets when repulsion often up to it
Hundred times or more of weight, therefore the superstructure of described device has the very strong tendency that oscillation is swung near equilbrium position, no
It can topple over easily.The variation of 2 magnetic flux of induction coil when to swing, considers following four kinds of situations:
1) upper magnet yoke 5 occupy among each lower yoke 4, that is, is in equilbrium position.Between upper magnet yoke 5 and each lower yoke 4
Width of air gap when being equal.Magnetic induction intensity in each lower yoke 4 is equal, and each 2 magnetic flux of induction coil is equal, each lower yoke 4
It is equal to the repulsion of upper magnet yoke 5.
2) swing so that 5 circular conical surface of upper magnet yoke and each lower yoke 4 composition circular conical surface at a distance of being most nearby located at some lower magnetic
4 middle position of yoke.Equilbrium position is compared, the magnetic flux decline of the induction coil 2 in the lower yoke 4 is installed on；It is installed on the magnetic yoke
2 magnetic flux of induction coil in the lower yoke 4 of relative position rises；The magnetic flux on induction coil 2 in another two lower yoke 4 due to
Non-linear possible rise of its demagnetizing curve may also decline, but amplitude of variation is much smaller than the amplitude of variation of preceding two lower yoke 4.
3) it swings so that 5 circular conical surface of upper magnet yoke and each lower yoke 4 form apart most nearby being located under certain two for circular conical surface
The middle position in 4 gap of magnetic yoke.Equilbrium position is compared, the magnetic flux decline of the induction coil 2 in two lower yoke 4 is installed on；Peace
Rise loaded on 2 magnetic flux of induction coil in another two lower yoke 4.
4) swing so that 5 circular conical surface of upper magnet yoke and each lower yoke 4 composition circular conical surface at a distance of being most nearby located at some lower magnetic
To the position between certain two lower yokes, 4 gap centre comprising the lower yoke 4 among yoke 4, this situation is situation 2) and 3)
Intermediate case.Equilbrium position is compared, in two lower yoke 4, is installed on the magnetic flux decline of the former coil 2, installation and the latter
The magnetic flux of induction coil 2 may be declined according to its demagnetizing curve and may also be risen, if rising its amplitude of variation answers very little, and
Illustrate to approach and situation 2 at this time).With the former opposite lower yoke 4 in above-mentioned two lower yoke 4,2 magnetic of induction coil being fitted into
It is logical to rise；The lower yoke 4 opposite with the latter in above-mentioned two lower yoke 4,2 magnetic flux of induction coil being fitted into are bent according to its demagnetization
Line, which may decline, to be risen, if declining its amplitude of variation answers very little, and illustrate to approach and situation 2 at this time).
According to above-mentioned analysis, the scheme connected between two kinds of induction coils 2 is designed:
It 1), can be only by each 2 induced electromotive force of induction coil since each 2 magnetic flux of induction coil during the swing changes
It is being superimposed after vertical rectification, the voltage being achieved in that has biggish rectifier loss.
2) in summary under four kinds of situations each 2 magnetic flux of induction coil analysis, if the magnetic flux on two opposite induction coils 2
It is obvious significant to change more other two induction coil 2, then generates phase back-emf on this two opposite coil 2；And other two coil 2
Although electromotive force due to demagnetizing curve it is non-linear may not be it is opposite, generate electromotive force absolute value much smaller than it is preceding two sense
Answer the electromotive force absolute value of coil 2.Then, the 2 different name end of induction coil in opposite two magnetic yokes is connected, two obtained strings
Electromotive force after connection is superimposed after being rectified respectively, and opposite former scheme can reduce voltage loss caused by rectification, is conducive to
Improve efficiency of energy collection.
For the present invention first is that structure is simple, each part manufacturing is more convenient；Second is that design comparison is reasonable, installation side
Just, third is that realizing two-dimensional wiggle collection of energy；Fourth is that improving collection of energy effect by eliminating friction and reasonable connection induction coil 2
Rate.
