Embodiment
As Fig. 1, 2, shown in 3, upper, lower fixed frame 1, one or more permanent magnet 3 is provided with between 2, three are given in figure, permanent magnet 3 adopts ferromagnetic material, as neodymium iron boron, be connected on fixed mount 1 by upper reset spring 7 above permanent magnet 3, permanent magnet 3 be connected on lower fixed frame 2 below by the next spring 8, how outside upper each permanent magnet 3 may correspond to, lower back-moving spring 7, 8, lower back-moving spring 8 is sleeved on passive hydraulic cylinder 10, passive hydraulic cylinder 10 is fixed on lower fixed frame 2, permanent magnet 3 is fixed on the piston rod of passive hydraulic cylinder 10, the coil 4 of band magnetic core is equipped with in the side, N.S pole of each permanent magnet 3, the arrangement of permanent magnet 3 is parallel to each other magnetic pole in the same way, namely each permanent magnet 3 is all arranged in order by N.S pole or S. N pole, between two permanent magnets 3, interval is equal, be arranged in same plane equably, on same height, in the both sides of each permanent magnet 3, namely both sides, N.S pole are equipped with the coil 4 of a band magnetic core 5, coil with magnetic core and permanent magnet 3 mutually alternate intervals are arranged on sustained height, coil 4 upper end with magnetic core and upper holder 1 are fixedly linked, lower end directly or by initiatively hydraulic cylinder 9 indirectly and lower fixed frame 2 be fixedly linked, each coil 4 may correspond to multiple active hydraulic cylinder 9, initiatively hydraulic cylinder 9 is communicated by the oil sump 11 bottom oil pipe 12 and lower fixed frame 2 with the bottom cylinder barrel of passive hydraulic cylinder 10.Upper and lower fixed mount 1,2 adopts the nonferromagnetic material of high strength to make, as aluminum alloy materials; Outside the permanent magnet 3 of said structure and the coil 4 of band magnetic core, be arranged with the peripheral magnetic core 6 of a circle, wound core 5 and peripheral magnetic core 6 adopt high conductivity material to make, as silicon steel;
Complete magnetic loop is formed at above-mentioned permanent magnet 3 and the outer peripheral magnetic core 6 being arranged with a trap conjunction of the coil 4 of band magnetic core; In FIG, oil sump 11 bottom lower fixed frame 2 is connected with external active hydraulic cylinder 9 by oil pipe 12, when External Force Acting is at active hydraulic cylinder 9, initiatively the piston movement of hydraulic cylinder 9 forms fluid pressure, this pressure enters passive hydraulic cylinder 10 through oil pipe 12, oil sump 11 conduction, under hydraulic action, the piston driving permanent magnet 3 of passive hydraulic cylinder 10 moves up and down; In fig. 2, initiatively hydraulic cylinder 9 is set in being, be fixed on lower fixed frame 2, bottom it, cylinder barrel is connected with oil sump 11, initiatively the piston rod of hydraulic cylinder 9 is connected with upper holder 1 by the coil 4 of band magnetic core, when upper holder 1 has external force or vibration, with the piston rod movement of moving winding 4 and initiatively hydraulic cylinder 9, and then fluid pressure is formed in the cylinder barrel of active hydraulic cylinder 9, this pressure enters passive hydraulic cylinder 10 through oil sump conduction, thus the promotion permanent magnet 3 be fixed on passive hydraulic cylinder 10 piston moves up and down; Initiatively hydraulic cylinder 9 and passive hydraulic cylinder 10 all according to practical application needs, can select single-stage or multistage hydraulic cylinder; All active hydraulic cylinder 9 piston cross-sections amass the ratio of ratio referred to as sectional area that sum and all passive hydraulic cylinder 10 piston cross-sections amass sum, in actual applications, for improving unit efficiency, for amplitude or produce the ratio that the less energy source of displacement should select larger sectional area, meanwhile, passive hydraulic cylinder 10 adopts multistage; For amplitude or produce the ratio that the larger energy source of displacement should select less sectional area, meanwhile, initiatively hydraulic cylinder 9 adopts multistage.
operation principle: the displacement that vibration of the present invention or pressure produce directly can be considered as the displacement of initiatively hydraulic cylinder 9 piston rod.Because built-in upper holder and initiatively hydraulic cylinder piston rod are fixed, Fig. 1 is the state of the present invention when not working, and the magnetic energy now through coil 4 is maximum; When active hydraulic cylinder 9 piston rod has vibration or line pressure shift occurs, drive passive hydraulic cylinder 10 piston rod upwards or move downward, namely permanent magnet 3 upwards or move downward, now, due to the change of permanent magnet 3 and coil 4 and magnetic core 5 relative position, cause the rapid reduction through coil 4 magnetic flux, when moving to maximum displacement point, when namely going up most or descend most, magnetic flux now through coil 4 is minimum, close to 0, according to the law of electromagnetic induction, magnetic flux change produces induced electromotive force; When upper holder 1 move return to balance point by maximum displacement point time, under the double action of recoil of spring power and vibration source restoring force, the magnetic flux through coil 4 increases sharply, and produces the induced electromotive force of respective direction.In whole process, permanent magnet 3 overcomes Ampere force acting, realizes moving being converted into electric energy.Magnet size in the present invention, coil turn, hydraulic cylinder type, the when spring strength of hydraulic cylinder piston sectional area all can be selected to determine according to focused energy size in practical application and applied environment, each coil can be connected or Parallel opertation, and concrete series-parallel system determines according to practical application.The electric energy be directly converted by the present invention is the irregular alternating current of waveform, needs external change-over circuit during output.
