A kind of working principle of the present invention: in each road resonance mechanism of vibration energy collector resonator system based on the asynchronous conversion vibration energy collector of four tunnel abreast-types that resonates; Main spring oscillator A126, secondary spring oscillator A131 and corresponding spring A132, A133 constitute a two-freedom vibration system; Collector is fixed on the large-scale macroscopic vibrations body (like subway roadbed, tunnel, bridge etc.); When the macroscopic vibrations body drives the collector vibration; The macroscopic vibrations body will provide displacement excitation for collector; When extraneous vibration source frequency is in the first order resonant frequency band range of collector, the main spring oscillator A126 of resonance mechanism, secondary spring oscillator A131 will take place to resonate strongly with the external world.At this moment, main spring oscillator A126 will obtain to equate with the vibration source frequency and amplitude increases the stable vibration of several times.The to-and-fro motion of main spring oscillator A126 in vertical plane through power amplification and the switching-over effect of reinforcement connecting rod A130, A111 and reinforcement connecting rod end cross sliding clock A134, is converted into the swing vibration of swing arm A120.Swing arm A120 drives the pawl disk B108 swing vibration on swing axis B105 and the swing axis B105.Block G and ratchet F are installed on the pawl disk B108, and ratchet F and ratchet B109 form the ratchet mechanism with unidirectional transmission agency.The swing vibration of pawl disk B108 is converted into the continuous turnover campaign of ratchet B109 through ratchet mechanism.Ratchet mechanism has unidirectional transmission agency: when certain constantly ratchet B109 after ratchet F thrust rotational velocity greater than the rotating speed of pawl disk B108; Ratchet B109 will promote ratchet F and overcome the small restoring force of torsion spring around the rotation of ratchet positioning screwn, and the gear teeth of while ratchet B109 slip over ratchet F to be continued to rotate along original direction; When ratchet B109 rotational velocity less than pawl disk B108 speed; Ratchet F will turn round around positioning screwn under the effect of torsion spring restoring force; And gently lean against on the side of block G, pawl disk B108 will drive block G and ratchet F rotates synchronously, promotes ratchet B109 thus and quickens once more.The continuous turnover of ratchet B109 moves through small coning gear shaft B117 and passes to bevel pinion B114, the bevel gear wheel C103 engagement of bevel pinion B114 and output system.Finally; The asynchronous turnover campaign of the terminal bevel pinion B114 of four tunnel changements arranged side by side; Be converted into the motion that bevel gear wheel C103 high-speed and continuous is had enough to meet the need through the switching-over of ratchet mechanism and the integration of four pairs of bevel gear pairs, the loadwheel C108 continuous high speed that bevel gear wheel C103 drives on large bevel gear shaft C107 and the axle again rotates.Thus, the vibrational energy of macrostructure body is by the vibration energy collector collection, and is converted into the rotational kinetic energy on the loadwheel C108, thereby realizes external output power.
Because in actual engineering; The vibration of macrostructure body is the multi-frequency superpositing vibration; And there is unavoidable otherness in the resonance mechanism of collector on mechanical mechanism; Therefore no matter four tunnel of vibration energy collector resonator system resonance mechanisms to be set to same natural frequency still be different natural frequencys, the vibration peak of four tunnel resonance mechanisms always alternately occurs, the output system of collector also is an asynchronous alternate from the torque excitation that No. four changements obtain; Thereby the frequency of the rotation of output system excitation is the vibration frequency sum of four tunnel resonance mechanisms arranged side by side always, thereby this vibration energy collector can reach the purpose of highly effective gathering.If extraneous vibration source frequency range is bigger; Can't guarantee that energizing frequency is in the frequency bandwidth of collector resonance all the time; Then collector can not be operated in best acquisition state; But,, always can guarantee that then the output system of collector can have strong external acting ability as long as four tunnel resonance mechanisms are not in antiresonance point simultaneously because this collector has the structural feature of arranged side by side four road asynchronous conversions; Yet the difference of suitable adjustment four tunnel resonance mechanism natural frequencys can be eliminated collector and be in this situation of antiresonance point, so this collector is with collecting efficiency height and adaptable advantage.
Because this vibration energy collector loadwheel can obtain the turnover campaign of continuous high speed, so can directly connecting load, it does work, also can it be connected with common generator and vibrational energy is converted into electric energy further realizes Conversion of energy and utilization again.In addition, this collector can also combine to set up collection network as shown in Figure 5 with hydraulic system.The loadwheel of collector H1 is connected with common oil hydraulic pump H2, and the outlet of oil hydraulic pump H2 connects an one-way valve H3 again and forms a cover vibration-hydraulic pressure collecting unit H.After a plurality of vibrations-hydraulic pressure collecting unit H parallel connection; High pressure oil is through common unidirectional oil hydraulic motor P of high pressure oil pipeline N input; Externally acting behind the input oil pressure of common unidirectional oil hydraulic motor P gathering multichannel vibration-hydraulic unit H; Low pressure oil after the oil hydraulic motor acting is back to each vibrating hydraulic collecting unit H through low pressure oil pipeline M again, and whole thus network has just formed a cover circuit hydraulic oil pipe system collection network.Because this collection network has the effect of vibration-hydraulic unit multiple spot distribution collection characteristics and the amplification of multi-channel parallel input oil pressure; Oil hydraulic motor will possess stronger external acting ability; Whole collection network has stronger vibrational energy acquisition capacity than single collector, is more conducive to the scale collecting utilization of vibrational energy.
This invention advantage and effect:
(1) this vibration acquisition device need not initiatively power consumption, non-pollution discharge, and the acquisition principle based on two degree freedom system resonance makes that the collector collection effect is obvious, collecting energy output is big.
(2) four tunnel of collector resonance mechanisms can be set near the same natural frequency according to macroscopic vibrations body vibration frequency characteristics, realize the collection of CF specific aim, also can four tunnel resonance mechanisms be set at different natural frequencies and realize that Multiband gathers on a large scale.
(3) the direct connecting generator of collector loadwheel is converted into electric energy with vibrational energy, convenient storage with utilize again.
(4) but the synthetical collection system of longspan in the space range, Multiband is set up in a plurality of collector and hydraulic system networking, be beneficial to the scale collecting utilization of vibrational energy.
