Description
Technical field
The present invention relates to a kind of power-supply system, relate in particular to the power-supply system that is used for a jacking equipment, the part potential energy that its recyclable this jacking equipment discharged, and be electric energy to utilize once again with this part potential energy converting and energy, reach the effect of energy conservation.
Background technology
Jacking equipment has been that the building site in part indispensable in the building structure of type now, the especially city is generally not enough, and building has to promote its height, reaches higher plot ratio.No matter so be to carry people or thing, jacking equipment miscellaneous in daily life everywhere as seen, and the running of jacking equipment, consumed energy is inevitably, therefore following the running of known jacking equipment and the correlation of energy consumption is stated in summary.
Please refer to Fig. 1, Fig. 1 is the schematic diagram of known jacking equipment.The running of the lift-launch that jacking equipment 10 mainly rises or descends by electric power (known power source is the AC mains power supply), its structure probably comprises a bearing structure 11, a drive system 12 and a brake gear 13.When jacking equipment 10 is the action of rising, that is bearing structure 11 rises to a higher position, can obtain one and be changed to positive potential energy difference compared to original position this moment, this potential energy difference by electric power for giving drive system 12 in the jacking equipment 10, then drive system 12 draws high bearing structure 11 gained, and most that therefore can be considered electric energy that jacking equipment 10 consumed converts potential energy (also having other fraction electric energy is that other device of being applied in bearing structure body or the jacking equipment is required) to." potential energy " speech that note that in the literary composition to be mentioned is meant " gravitional force ".
In addition, when the jacking equipment desire descends, that is bearing structure 11 is when desiring to drop to position lower in the space, and is most of then running and control by drive system 12 and brake gear 13 makes bearing structure 11 drop to this lower position with a stable speed.But can find this moment, be present in the potential energy difference (being changed) between script high position and this lower position by electric energy, when bearing structure 11 descends, by brake gear 13 slow down consume, make its can descend in a stable speed (slowing down bearing structure 11) by acceleration that potential energy difference produced.
Therefore, when known jacking equipment carries out the repetitive process of " rising " and " decline ", there are many electric energy in operation, to be consumed inevitably and use up.And may need up to a hundred times with present jacking equipment one the sky, following number of times, be meant company's row number or department store especially, thus, just more need to consume the electric energy of " various ", along with energy prices are surging, must pay the very electric energy expense of great number especially.
In this, in the operating mode of known jacking equipment, it is (be meant especially when bearing structure 11 is decline, consume when being slowed down by brake gear 13) that is wasted that the quite huge energy is arranged.If the potential energy difference that jacking equipment discharged suitably can be reclaimed and utilization again, can reach the effect of energy savings, also can reduce the generation (brake gear is when slowing down bearing structure, and potential energy difference originally converts heat energy to) of used heat.Yet desire reclaims potential energy, must be by energy storing device and energy conversion device, and with the mode that potential energy converting and energy is for the benefit of stored, in addition, considering the energy that generally uses in the jacking equipment is electric energy, therefore potential energy converting and energy is become electric energy just to be the most feasible mode.
Though wherein energy conversion device can be implemented by known generator easily, energy storing device can't utilize known common electric capacity and battery to implement efficiently; Illustrate, the energy storage class of the energy storage elements of widespread usage has three kinds now: 1. power conversion is stored for the chemical energy form, wherein traditional battery and genus are at this type.2. power conversion is stored for the physical energy mode, as traditional electric capacity.3. be that the form that has physical energy and chemical energy concurrently is stored with power conversion, this type of includes super capacitor.
Generally speaking, though electric capacity is comparatively simple on processing procedure,,, can only use as of short duration energy storage so its energy storage capacity is less relatively because of its energy storage density is not high.And conventional batteries, mainly be to utilize the mode of chemical energy to carry out the energy storage, therefore its energy storage density obviously is better than general electric capacity, and can be applicable to various electric power supply apparatus, but shortcoming is: the moment electric power output that it can produce can be subject to chemical reaction rate, and can't discharge and recharge or carry out high power output fast, and it is limited to discharge and recharge number of times, easily grows variety of issue when excessively charging and discharging; For example: present employed storage battery though bragging about reusablely, but has the restriction in its life-span.repeatedly discharge and recharge or long-time obsolete situation under, the capacity of storage battery can descend, and damage easily, reason is that storage battery is to utilize chemical energy to be converted to electric energy, chemical substance will often be protected its activity, and it is rotten just to be unlikely to lose efficacy, when original compound activity all uses up or nearly use up, just can't carry out new chemical reaction again, and then cause storage battery aging and declaration is died of old age.And super capacitor is a kind of element between between battery and electric capacity, claim electric double layer capacitance (Electrical Double-Layer Capacitor) again, because of passing through the energy storage of part physics, the chemical energy storage framework of part simultaneously, so it has the capacity bigger than common electric capacity, but its shortcoming is: because of chemical material tool chemical characteristic is arranged, and easy electric leakage shortcoming just like battery, add that again because of also having part be the fast phenomenon of the velocity of discharge of physical characteristic, just producing thus has the phenomenon that will soon not have electricity, can't reach effective storage function.Even, the pressure withstanding degree of super capacitor is not high, internal resistance is bigger, thereby cannot be used for alternating current circuit, if and the improper use meeting causes phenomenons such as electrolyte leakage, because the inborn characteristic of super capacitor, power consumption too fast if need to continue to use with necessity frequent to its charging, cause it and be not suitable for as a main supply of electric power source.
So above-mentioned known energy-storage travelling wave tube also can't reach advantages such as long (high charge-discharge number of times), high energy storage density of desired life-span of jacking equipment, transient high power output and fast charging and discharging simultaneously.Therefore, because known electric capacity and battery, the energy storage density that it possessed is not sufficient to make it to store the abundant electric energy that is enough to supply the jacking equipment running under a desirable weight, in other words, known electric capacity or battery, application in this kind situation will not possess the economic benefit of making us accepting, be utilized once again because if want in this case to store sufficient electric energy so that reclaim, with known electric capacity or the formed energy storing device of battery quite surprising weight and volume will be arranged, thus, concerning jacking equipment, just (jacking equipment is to reach to bear this extra weight and volume to have become obstacle on the real work, in primary structure and design, must consider again), so therefore the advantage that energy recuperation brought will have a greatly reduced quality.
Summary of the invention
Therefore, purpose of the present invention, be that a kind of power-supply system is being provided, the energy storing device of advantages such as application has low cost, energy storage density height, volume is little, in light weight, capacity big, Maintenance free, long service life, the low pollution of environmental protection, and then the electric energy of potential energy converting and energy when reclaiming the storage jacking equipment and descending, to provide load required electric power again, expectation can reach the energy-conservation power-supply system of utilizing again.

The operating principle that further specifies magnetic capacitance is as follows.The material phenomenon that resistance changes under certain magnetic field is called " magneto resistance effect ", and magnetic metal and alloy material generally all have this magneto-resistor phenomenon, and generally, the resistivity of material only produces slight reducing in magnetic field; Under certain condition, the amplitude that resistivity reduces is quite big, exceeds more than 10 times than the magnetoelectricity resistance of common magnetic metal and alloy material, and can produce very huge magneto resistance effect.If further combined with the Maxwell-Wagner circuit model, also may produce very huge magnetocapacitance effect in the magnetic-particle complex media.
In known capacitance, capacitance C is by the area A of electric capacity, the DIELECTRIC CONSTANT of dielectric layer
0ε
rAnd the thickness d decision, as
Yet in the present invention, magnetic capacitance 100 mainly utilizes the magnetic dipole of proper alignment in first magnetic pole 110 and second magnetic pole 120 to form magnetic field, the electronics of storage inside is rotated towards same spin direction, carry out neat arrangement, so can be under similarity condition, hold more electric charge, and then increase the storage density of energy.Simulate in known capacitance, the operation principles of magnetic capacitance 100 is equivalent to the dielectric constant that is used for changing dielectric layer 130 by magnetic field, so cause the significantly lifting of capacitance.
In addition, in the present embodiment, interface 132 between interface 131 between first magnetic pole 110 and the dielectric layer 130 and second magnetic pole 120 and the dielectric layer 130 is a uneven surface, with by increasing the mode of surface area A, further promotes the capacitance C of magnetic capacitance 100.
Please refer to Fig. 4, Fig. 4 is the structural representation of an embodiment of first magnetic pole 110 shown in Figure 3.As shown in Figure 4, first magnetic pole 110 is a sandwich construction, include one first magnetosphere 112, one separator 114 and one second magnetosphere 116, wherein separator 114 is made of nonmagnetic substance, first magnetosphere 112 and second magnetosphere 116 then include the electric conducting material of tool magnetic, and when magnetization, by different extra electric fields, make the magnetosphere 112 of winning have different directions respectively with magnetic dipole 113 and 117 in second magnetosphere 114, for example in a preferred embodiment of the present invention, magnetic dipole 113 and 117 direction are oppositely, and can further suppress the leakage current of magnetic capacitance 100.In addition, it is emphasized that, the structure of first magnetic pole 110 is not limited to aforesaid three-decker, and can be in a similar fashion, with a plurality of magnetospheres and continuous staggered the stacking of nonmagnetic layer, adjustment by magnetic dipole direction in each magnetosphere further suppresses the leakage current of magnetic capacitance 100 again, even reaches the almost effect of leakage current.In addition, the structure of second magnetic pole 120 also can adopt the structure of above-mentioned first magnetic pole 110, and this design variation also belongs to category of the present invention.
In addition, because known energy-storage travelling wave tube is stored in the mode of chemical energy mostly, therefore all need to have the dimensions, otherwise tend to cause declining to a great extent of efficient.Compared to this, magnetic capacitance 100 of the present invention is stored in the mode of energy of position, and more efficient energy storage mode can be provided thus, thereby magnetic capacitance of the present invention can be used as a preferable supply of electric power source.
Please refer to Fig. 5, Fig. 5 is the schematic diagram of an embodiment of magnetic capacitor module 200 of the present invention.Brought forward is described, in the present embodiment, be to utilize manufacture of semiconductor on a silicon substrate, to make a plurality of undersized magnetic capacitances 100, and by the proper metal processing procedure, form electrical connection 100 of a plurality of magnetic capacitances, thereby constitute a magnetic capacitor module 200 that includes a plurality of magnetic capacitances 100, again with the supply of electric power source of magnetic capacitor module 200 as energy storing device or external device (ED).In the present embodiment, a plurality of magnetic capacitances 100 in the magnetic capacitor module 200 are electrically connected in the mode of similar array, yet the present invention is not limited to this, and can be according to the supply of electric power demand of different starting drives, adjust magnetic capacitance and form, to satisfy the supply of electric power demand of various different devices with series, parallel or series-parallel mode.
Then the embodiment of the designed jacking equipment of power-supply system of the present invention is adopted in explanation.Please refer to Fig. 6, the jacking equipment 600 among the figure including (but not limited to): bearing structure 601 is coupled to a cable wire 610; Drive system 602 is coupled to cable wire 610, necessary control and power when bearing structure 601 rise and fall can be provided; Power-supply system 603 is coupled to drive system 602, required electric power in the time of can supplying with drive system 602 running; Roller 642 is coupled to Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630 and rail set 640, in order to when bearing structure 601 descends, converts potential energy difference to kinetic energy; Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630 is coupled to roller 642 and power-supply system 603, and the kinetic energy that utilizes roller 642 to produce generates electricity, and with the magnetic capacitor module 607 of power storage in power-supply system that produces; Brake gear 622 is coupled to rail set 640, in the time of can working as bearing structure 601 declines it is slowed down, and can keep stable speed when bearing structure 601 is descended; And rail set 640, in order to provide roller 642 and brake gear 622 1 active forces to produce point, roller 642 is rolled along this produce kinetic energy, and 622 pairs of rail sets of brake gear, 640 generation active forces (for example frictional force), so that bearing structure 601 is slowed down.In addition, power-supply system 603 has comprised two supply of electric power sources, be respectively power supply supplying module 605 and magnetic capacitor module 607, wherein magnetic capacitor module 607 also can be by Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630 to its electric energy that charges and produced with storage Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630 except supplying the electric power.Power-supply system 603 comprises a power source regulating circuit 640 in addition, in order to adjust power supply module 605 and the ratio of magnetic capacitor module 607 in out-put supply.Please note, during actually application, power supply module 605 in the present embodiment can correspond to the AC mains power supply in the known jacking equipment, also can may supply the power supply of jacking equipment required electric power by corresponding other, the present invention does not make restriction to this, so only name with power supply module 605.In addition, the concrete methods of implementing of power source regulating circuit 640 have a lot, and should be those skilled in the art and can understand easily, so seldom be described further at this.
Below explain the application of the power-supply system 603 of present embodiment.At first, suppose that magnetic capacitor module 607 does not contain any electric charge (can't supply capability), when jacking equipment 600 is controlled through an operator, when desiring to make its bearing structure 601 to rise, the electric power that this moment, drive system 602 can be provided by the power supply module in the power-supply system 603 605 makes that to produce a power that draws high by this bearing structure 601 is able to therefore be drawn high.Through above step, bearing structure 601 finally just is arranged in higher position, space.
When if the operator desires to make bearing structure 601 to move to position lower in the space, this moment, the running and the control of drive system 602 can make bearing structure 601 begin to descend, in the process that descends, roller 642 begins to roll on rail set 640, and the kinetic energy that is produced when rolling has just driven Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630, makes it begin to produce electric energy.Note that because roller 642 has consumed most potential energy differences with rail set 640 effects, get final product so brake gear 622 only need wait bearing structure 601 slowed down where necessary.The electric energy that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 630 is produced in said process is stored to magnetic power module 607 subsequently, though can after supply be the required electric power of bearing structure 601 inner members (for example electric light) or drive system 602, and by power source regulating circuit 604, the voltage that magnetic capacitor module 607 can be supplied and current conversion are bearing structure 601 and drive system 602 acceptable voltage levels.Simultaneously, power source regulating circuit 604 also can be adjusted in the out-put supply of power-supply system 602, and both ratios of being provided of power supply module 603 and magnetic power module 607 make jacking equipment 600 can obtain stable supply of electric power.One of reason that power source regulating circuit 604 is set is to be not enough to supply bearing structure 601 for fear of 607 electric energy stored of magnetic capacitor module to rise to a higher position, this moment is by adding the supply of electric power of power supply module 605, so that possessing enough electric power, drive system 602 allow bearing structure 601 be risen to desired higher position, in addition, also may command magnetic capacitor module 607 and power supply module 605 give other device in the jacking equipment 600 to supply with abundant electric power to power source regulating circuit 604.
The structure that note that jacking equipment shown in Figure 6 600 only belongs to a conceptual explanation, is not the execution mode that the present invention limits.For instance, converting potential energy difference to kinetic energy by roller 642 and rail set 640 only is an exemplary illustrated, in fact potential energy converting and energy can be become the device of kinetic energy a lot, all can be applied to jacking equipment 600, is difficult to enumerate one by one at this.Main spirit of the present invention again is to utilize the high energy storage density of magnetic capacitance itself to be used as a energy storage device in the power-supply system, so that electric energy is recycled, so any design variation of being done at potential energy converting and energy mechanism still belongs to invention category of the present invention in fact.
Known jacking equipment is when descending, in order to keep stable decrease speed, the main potential energy that slows down and descend and discharged because of bearing structure by brake gear to consume, make it be unlikely to convert to too much kinetic energy, and the potential energy that bearing structure possessed is to draw high this bearing structure gained by drive system, and drive system draws high this bearing structure by a supply of electric power, this measure is equivalent to convert electric energy to potential energy and stores, and this bearing structure is when dropping to low relatively position, just by brake gear potential energy is consumed in order to avoid this potential energy converting and energy is too much kinetic energy, make that bearing structure is out of control to be fallen, but that such function mode has been wasted is many before with potential energy mode electric energy stored.Compared to known jacking equipment, the present invention has passed through energy conversion device, the part of the potential energy that jacking equipment is discharged when bearing structure descends is converted to electric energy, and be stored in the energy storing device, therefore can be when this bearing structure desire rises, give the required electric power of bearing structure by energy storing device for giving drive system or providing again, reclaim and the effect of utilizing again with Danone, thereby make the electric power of power-supply system be unlikely to excessively to be wasted and can to recycle.
From the above, pass through magnetic capacitance, realized the energy storing device of passing inexecutable jacking equipment, this is because the traditional electrical energy storage density that perhaps battery is lower can make with it is that the energy storing device of basic engineering produces excessive weight, cause to be implemented on economically in the jacking equipment and (certainly will change the structure and the cost of lowering or hoisting gear), so power-supply system of the present invention can be under the consideration that takes into account cost and usefulness, carry out the energy recovery of jacking equipment and utilize again, to reach the reality of energy savings.
The above only is the preferred embodiments of the present invention, and all equalizations of doing according to claims of the present invention change and modify, and all should belong to covering scope of the present invention.
