Description
Technical field
The invention belongs to technical field of energy recovery, particularly to a kind of energy recycle device based on jump phenomena.
Background technology
Energy recycle device utilizes the mode such as piezoelectric, electromagnetic induction mechanical vibrational energy is converted to electric energy and stores up
Depositing, such as, the mechanical kinetic energy that staff swings is converted to electric energy by hand-held low energy consumption torch, powers for its LED, thus without
External cell is powered, and decreases the old and useless battery pollution to environment, and is applicable to the environment of field equal energy source shortage.Except this it
Outward, energy recycle device also may be installed (such as water pump, electromotor etc.) in the reciprocating plant equipment of part, these is set
Standby mechanical energy is converted to electric energy, thus provides power supply for other mini-plants.
It is the biggest that the internal mechanical structure of energy recycle device produces reciprocating amplitude within a cycle, its electromagnetism sense
Should be able to power or the change in voltage that makes piezoelectric produce just can be the biggest, correspondingly, energy recovery efficiency is the highest.Therefore, for improving
Energy recovery efficiency, needs internal mechanical version reasonable in design so that it is can produce under the incentive action of external vibration
Big amplitude.
Summary of the invention
It is an object of the invention to: a kind of energy recycle device based on jump phenomena is provided, can be expeditiously by mechanical energy
Amount is converted to electric energy.
The technical scheme is that a kind of energy recycle device based on jump phenomena, it includes: square plastic magazine,
Rustless steel shell fragment, piezoelectric ceramic piece, small-sized Magnet and long bar magnet；
It is provided with support in square plastic magazine；One end of rustless steel shell fragment is fixed on support, and other end connection has small-sized
Magnet, rustless steel shell fragment constitutes cantilever beam structure；Piezoelectric ceramic piece is pasted onto the side fixing end near rustless steel shell fragment, piezoelectricity
The two poles of the earth of potsherd connect wire；Long bar magnet is arranged on the inwall of square plastic magazine, relative with small-sized Magnet homopolarity；
Square plastic magazine is placed on vibration source equipment.
Stainless steel substrates defines cantilever beam structure, when small-sized Magnet deviation horizontal level is x, is produced by stainless steel substrates
Rigidity restoring force is:
In formula, x is that small-sized Magnet deviates horizontal distance, and E is the tension and compression rigidity of stainless steel substrates, and l is small size magnetic irony
Heart distance stainless steel substrates distance between installation site on bearing.
When the small-sized Magnet of stainless steel substrates end is near rectangle Magnet, i.e. both spacing are Δ, the most small-sized Magnet
The non-linear repulsive force being subject at diagram vertical direction is:
In formula, η and M is respectively magnetic capacity and magnetic pole strength.Therefore, when reducing Δ so thatCan cause
F2＞ F1, thus each stainless steel substrates " warpage " can be caused, it may be stablized at the A shown in Fig. 3 or B location；Δ is the least, " sticks up
Bent " degree is the biggest." warpage " positional distance horizontal plane is respectively as follows:
This device is arranged in the plant equipment of vibration, it is assumed that small-sized Magnet is now at location A, if equipment produces
Impact, random or simple harmonic oscillation cause the vibration of stainless steel substrates so that the Oscillation Amplitude of small-sized Magnet reaches | xA|, can cause
Stainless steel substrates jumps to " warpage " position B from " warpage " position A, thus causes each piezoelectric ceramic piece generation wide-range strain, to
Outer release electric energy.The two ends copper conductor of this device is connected with charging circuit, by charging circuit, piezoelectric ceramic piece is produced
Electrical power storage, thus realize energy regenerating.
Beneficial effect: the present invention " saltatory " frame for movement can carry out large-amplitude vibration under the effect of excitation, the suitableeest
For energy recycle device." saltatory " structure should utilize Magnet repulsive interaction flexing cantilever beam structure, so that cantilever beam structure
Occur " warpage ", define the nonlinear vibration subsystem with bistable fixed point.With traditional line only having a stable equilibrium point
Property oscillator system different, this structure has two stable " warpage " positions, when by external vibration incentive action, cantilever beam
Meeting " warpage " position " jump " rapidly from which is to another " warpage position ", thus makees big amplitude fortune at short notice
Dynamic, if post piezoelectric in cantilever beam end, this " jump " phenomenon can make piezoelectric have big strain amplitude, cause
Change in voltage amplitude becomes big, and the efficiency being converted to electric energy can increase.

Detailed description of the invention
Seeing accompanying drawing, a kind of energy recycle device based on jump phenomena, it includes: 6,6 rustless steels of square plastic magazine
2,6 pieces of piezoelectric ceramic pieces of sheet, 4,1 rectangle Magnet 5 of 3,6 small-sized Magnet.Wherein, it is provided with support 1 in square plastic magazine 6；
One end of rustless steel shell fragment 2 is fixed on support 1, and the other end connects small-sized Magnet 4, and rustless steel shell fragment 2 constitutes cantilever beam knot
Structure；Piezoelectric ceramic piece 3 is pasted onto the side near the fixing end of rustless steel shell fragment 2, and the two poles of the earth of piezoelectric ceramic piece 3 connect wire；
Long bar magnet 5 is arranged on the inwall of square plastic magazine 6, relative with small-sized Magnet 4 homopolarity, can be that S level is to S level, it is also possible to for N
Level is to N level；
Square plastic magazine 6 is placed on vibration source equipment.
Described small-sized Magnet 4 is cube structure, for NdFeB material.
Described rectangle Magnet 5 is NdFeB material.
Repulsive interaction between long bar magnet 5 and small-sized Magnet 4 causes each stainless steel substrates 2 " warpage " so that it is stable in Fig. 3 institute
The A shown or B location.When this device is arranged in the plant equipment of vibration, vibration equipment causes the vibration of stainless steel substrates 2, leads
Cause stainless steel substrates 2 and jump to another " warpage " position from " warpage " position, thus cause each piezoelectric ceramic piece 3 on it
Raw wide-range strain, outwards discharges electric energy.The two ends copper conductor of this device is connected with charging circuit, will pressure by charging circuit
The electrical power storage that electroceramics sheet 3 produces, thus realize energy regenerating.
