In at least one embodiment of the disclosure, present disclose provides a kind of Used in Boundary Lubrication of Magnetic Fluids type gap resonant frequencies
Vibrate electromagnetism energy accumulator comprising stator and mover two large divisions.As shown in Figure 1, stator includes：Package tube 3, package tube 3 are
The cylinder of upper and lower ends opening；Upper end cover 1 and lower cover 10, the upper port of package tube 3 is arranged in upper end cover 1, to close
The lower port of package tube 3 is arranged in upper port and lower cover 10, to closed lower mouth；First spring 2 and second spring 9,
First spring 2 and second spring 9 are arranged in package tube 3, and the first spring 2 is fixed on upper end cover 1, and second spring 9 is solid
It is scheduled on lower cover 10；Coil 4, coil 4 is wrapped in 3 outside of package tube, and is prepared by conductive material, for the magnetic in movement
Induced current is generated in.Mover includes：Magnet 8, magnet 8 are prepared by magnetic material, and magnet 8 is arranged in package tube 3, and
Between the first spring 2 and second spring 9, magnet 8 can move up and down in package tube 3, during up and down motion
It can be in contact with the first spring 2 and second spring 9 and compress the first spring 2 and second spring 9.
When on the hydraulic pump when the energy accumulator is fixed on high-frequency vibration source, such as in working, the vibration in high-frequency vibration source
It is transmitted to the device, the mover in package tube 3 is forced along the up-down vibration of package tube 3.As shown in Fig. 2, when mover moves to one
Positioning can compress the first spring 2 or second spring 9 when setting.After and by spring apply reaction force rush continue to negative side
To movement.So the spring being fixed on two end caps can be realized the kinetic energy of mover and the mutual conversion of elastic potential energy, prolong
Long time of vibration.If the kinetic energy that mover obtains every time can be lost due to collision end cap without spring；And if be provided with
Spring, so that it may kinetic energy be passed into spring, spring passes to mover again.The up-down vibration of mover so that itself and package tube 3 it
Between form relative motion, to produce a changing magnetic field.By the law of electromagnetic induction it is found that a part of closed circuit
When conductor does cutting magnetic induction line movement, induced current will be generated on conductor.The relative motion of mover and package tube 3 and formed
One changing magnetic field, therefore the coil 4 being fixed on outside package tube 3 produces induced current under changing magnetic field.This is just
It is the principle that energy accumulator converts the energy of high-frequency vibration to electric energy.It can be to need continued power using the electric current that energy accumulator generates
Micropower electronic product and microminiature remote sensing detecting element power supply, solve sensor component and need asking for power supply
Topic, realizes self-sufficient, is easy to implement wireless sensor network.
In accordance with another embodiment of the present disclosure, magnetic fluid 5 is filled between the inner sidewall and mover of package tube, to keep away
Exempt from directly contacting for mover and the inner sidewall of package tube 3, magnetic fluid 5 is for reducing mover during up and down motion and package tube
Friction between 3 inner sidewall.
The magnetic fluid 5 for being filled in package tube 3 and mover gap can flow under the influence of a magnetic field and be fixed on magnetic field strength
High place, position as shown in Figure 1.Magnetic fluid 5 is bonded with mover and the interaction strong in contact surface.Due to design
The side of symmetry, mover is identical by the power size of magnetic fluid 5, and mover and package tube 3 keep coaxial position.If mover is inclined
From central axis, then the active force of the magnetic fluid 5 of narrow side will increase, and the power of the opposite other side then reduces, and then mover
It will be pushed back central axis, kept always with package tube 3 coaxially, here it is magnetic fluids 5, and mover to be made to float on the original at 3 center of package tube
Cause.
Magnetic fluid 5 in package tube 3 and mover gap flows under magnetic fields as lubricant medium and is fixed on magnetic
The high place of field intensity, package tube 3 and mover are kept apart, so that the running quality of mover is improved, are reduced because of friction
Caused energy consumption substantially increases the energy recovery efficiency of system.
The disclosure can select carbon fiber pipe as package tube 3.In addition, the disclosure selects the spring of high rigidity as first
Spring 2 and second spring 9, such as waveform spring, ring spring, pagoda spring or disk spring etc..
The intrinsic frequency calculation formula such as following formula of spring：
Wherein, A is frequency, and K is the stiffness coefficient of spring, and m is the load bearing quality of spring.
Know that K is bigger by (1) formula, A is bigger, therefore high-strength spring is able to achieve high-frequency vibration.In addition, above-mentioned listed spring
All have many advantages, such as that small in size, occupied space is few, stress is symmetrical, the deformation of very little can bear biggish load, be very suitable to
The lesser situation of energy accumulator axial space of disclosure design, can make energy accumulator compact overall structure.
According to the another embodiment of the disclosure, there is gap between mover and the first spring 2 and second spring 9, thus
Form interstitial vibration.This section of gap adds somewhat to the moving displacement of mover, and then overcomes the change of high rigidity spring
The small disadvantage of shape.The increase of moving displacement is so that amplitude increases, to improve the power of mover, this design is substantially increased
The energy recovery efficiency of energy accumulator.
According to the another embodiment of the disclosure, magnet 8 is permanent magnet, and permanent magnet is by samarium cobalt permanent magnet body material or neodymium iron
The preparation of boron permanent magnet material.The reason of selecting permanent magnet is that it can also retain higher remanent magnetism for a long time under open-circuit condition, is not easy
Magnetization is also not easy loss of excitation.Mover can also include two pieces of iron blocks 6, the upper and lower ends in magnet 8 are respectively fixedly connected with, so that iron block
6 and magnet 8 can move up and down in package tube as a whole.The effect of iron block 6 is to improve magnetic direction, and conduct
Conductor and permanent magnet constitute closed magnetic circuit, as shown in Figure 3.
The permanent magnetic field that permanent magnet 8 and magnet 6 are formed is constant always, so magnetic fluid 5 will also be suspended in designated position always
On, lubricating status is stablized, to form continuous lubrication, eliminates abrasion, improves the efficiency of energy accumulator energy regenerating.
Energy as much as possible is obtained for recycling, reduces the air drag loss between mover and stator is critically important one
A aspect.For the loss for solving this aspect, the disclosure has done following design：Magnet 8 and iron block 6 are centrally formed with through-hole, make
Obtain the space connection of mover upper and lower ends；Or mover further includes hollow pipe 7, magnet 8 and iron block 6 are centrally formed with through-hole, empty
Heart pipe 7 is arranged in through-hole, is fixedly connected with magnet 8 and iron block 6, so that the space of mover upper and lower ends is connected to.Using in this way
Design, can be connected to mover up and down two sides cavity, allow two sides cavity in air mover vibrate when can be swimmingly
Flowing, to reduce air drag.
When the intrinsic frequency of mover is equal with the vibration frequency of vibration source (for example, hydraulic pump), mover can resonate,
Very big energy is generated in the periodic vibration of very little.At this point, mover is known as resonance mover.According to formula (1) it is found that by changing
Become the stiffness K of the first spring 2 and second spring 9, the quality m of mover, Used in Boundary Lubrication of Magnetic Fluids type gap resonant frequencies can be made to shake
The intrinsic frequency of dynamic electromagnetism energy accumulator is equal with the external frequency of vibration source.
It is illustrated in figure 4 the Distribution of Magnetic Field figure of annular permanent magnet, as seen from Figure 4, further away from permanent magnet, magnetic induction line is got over
Sparse, magnetic field strength is weaker, and closer to permanent magnet, magnetic induction line is more intensive, and magnetic field strength is stronger.When 4 position one of iron block 6 and coil
A pair of seasonable, resonance mover is in equilibrium state, 4 cutting magnetic induction line minimum number of coil.When coil 4 and permanent magnet 8 are corresponding
When, 4 cutting magnetic induction line quantity of coil is most, as shown in Figure 5.When resonance mover speed maximum, pass through the magnetic flux change of coil 4
Rate is maximum, and in the case where 4 the number of turns of coil is certain, the induced electromotive force of generation reaches maximum；As resonance mover moves closer to
Equilbrium position, the magnetic flux across closed circuit tail off, and the induced electromotive force of generation reduces.Meanwhile resonance mover deviates balance
The direction of position is different, and the direction for generating induced electromotive force is also different, and the inductive current direction of generation is also different, as shown in figure 3,
So energy accumulator can generate an alternating current.
In conclusion by the induced current that can convert high-frequency vibration to coil, it can be achieved that the energy of high-frequency vibration returns
It receives.The Used in Boundary Lubrication of Magnetic Fluids type gap resonant frequencies vibration electromagnetism energy accumulator structure of the disclosure is simple, at low cost, applied widely,
High-frequency vibratory energy, and output power can flexibly be absorbed.The energy of high-frequency vibration generation is taken full advantage of, this part of energy can be
Monitoring sensing components lasting electric power is provided, solve the problems, such as that sensor component needs power supply, realize it is self-sufficient,
It is easy to implement wireless sensor network.
It will be understood by those of skill in the art that above embodiment is used for the purpose of clearly demonstrating the disclosure, and simultaneously
Non- be defined to the scope of the present disclosure.For those skilled in the art, may be used also on the basis of disclosed above
To make other variations or modification, and these variations or modification are still in the scope of the present disclosure.
