Description

Railway and train energy-conversion technique

The technical field of the invention: railway locomotive, train

Technical background of the present invention: well-known, railroad train carrying capacity is powerful, is the means of delivery of current land maximum.Simultaneously, its occupation of land and affiliated facility thereof also are huge, and each joint rail, road pillow and the formed railway line of roadbed thereof are the usefulness for train driving for many years.But, very big potential economic benefit is arranged between huge railroad bed and the powerful train, should be excavated and be used, realize higher application and the economic value of railroad train.

Theory of the present invention is the method for building and using at above-mentioned railway, according to " energy conservation and transformation law " application that become more meticulous, the energy and the railway technology of the use preciousness of science more, the energy that railway, train contained is extract, and the source that makes its energy is more near nature, harmony and natural.Especially possessing under the condition of building the high speed railway net now, be fit to application of the present invention more, simultaneously, this economy and operation that also can promote national high speed railway is worth.

The detailed content of the technology of the present invention:

The first, the problem to be solved in the present invention:

1. the propulsive effort of the especially quick motor-car of railway locomotive is realized by electrical motor by electric power, (using the locomotive of fuel oil or other dynamic methods certainly in addition).The operation of finishing full train will consume the kinergety that electric power changes into, and has also promptly finished transportation or has been called and finished acting, and the energy of its consumption has changed into corresponding kinetic energy.The present invention will change the energy of wiring back with its kinetic energy, though can not realize hundred-percent Conversion of energy in the middle of this simultaneously again in its this kinetic energy acting, but in line with energy savings, cut the waste, realize the principle of scientific as much as possible application natural resources, optimize railway science application engineering.

2, from the values of input and output: huge railway line and huge train are the basic characteristics of railway, simultaneously, also make railway possess the ready-made condition that the kinetic energy secondary is changed into electric energy.Comparatively speaking, other means of deliverys such as the relative automobile of train, it is longer to have unit time that travels at the uniform speed, general equal reaching more than 20 minutes, even reached at the some hrs that has.Present technique is to guarantee the normal safe operation of train and do not exceeding under the precondition of load capacity, with the special generating set of operating train momentum by setting up, transform once more and extract potential electric energy, and supply with train self on the spot and use with electrical unit, the operation technique method near nature, the energy is more rigorous more to make railway transportation.

The 2nd, the technical solution adopted in the present invention:

Know-why of the present invention is made of jointly three parts:

First: make train and carry the Idiotype generator principle: with scientific theories such as the laws of electromagnetic induction is that this electrical generator of principle manufacturing is by stator, rotor, awards fan rotor and the stator support bearing frame is a chief component.Flowing of the ambient air that train the time is driven in operation, with this machine of promotion award the fan rotor rotation, drive the rotor rotation that is attached thereto together simultaneously, cutting magnetic line sends electric energy;

Second: must select the dedicated location on the train: according to the basic functional principle of this electrical generator, install and use in place the easiest, that can obtain quick moving air in a large number on the selection train.Any position in the bottom space position of train or train top all is that this electrical generator is optimal control position, can obtain best task performance;

The 3rd: train is except that the energy resource supply of propulsive effort and necessity, and the electricity consumption source of any life, office property consumer all can be this machine and produces, and therefore, the energy resource supply of this electrical generator in the operation process of whole trains will occupy an important position.

Concrete technical method is as follows:

One. train carries the manufacturing of Idiotype electrical generator:

Method: the stator of this electrical generator, rotor still prolong with current electrical generator science and technology theoretical, special is that this electrical generator needs design and installation simultaneously to obtain the fan rotor of awarding of moving air, 1. the magnetic field environment of Idiotype generator unit stator is to be formed by N and S polar curve circle, it can produce magnetic field under energising, magnetic field disappears during outage, reach as required the order ground, particularly train that use in extraordinary circumstances, can in time control and operate.2. the two ends center-point of this machine rotor is for prolonging the beaming roller of coming out, be called " center beaming roller ", itself and stator support bearing point of connection place make suitable prolongation, get final product below generally optionally remaining on 100mm, at this prolongation beaming roller special use is installed partly and awards fan rotor, and firm linking together (accomplishing detachable).Also can do prolongation once more in case of necessity, in order to install another pivot shaft bolster additional, in order to obtain better rotational stabilization at this beaming roller and the point of connection of awarding fan rotor.Also can directly will award the beaming roller outside that fan rotor is contained in rotor, and be connected to together on the pivot shaft bolster, more compact than method 2.3. there is a fan at every generator amature two ends, special version be: in order to catch more wind energy, also can carry out many fans on demand and install, at this moment the diameter of its flabellum can be done corresponding dwindling, and helps the space of installing like this.When the speed of train movement reaches more than the 50km/h or during faster speed, caused its peripheral air to flow fast, utilize this wind energy to drive and award fan rotor, drive rotor rotation cutting magnetic line, send electric energy.

Technical requirements: 1. the technical requirements of extraordinary special-shaped electrical generator will fully take into account the space constraint and the environment for use factor of installation environment.This machine of finished product outward appearance should become relative slender type shape, length can be at 800-1000mm, relative thickness should be at 300-350mm (contain and award the fan rotor diameter), have certain stream line pattern, shell is reserved for electrical generator heat-dissipation ventilating air porthole, anti-rainwater, anti-lightning strike, prevent fires, have the damping configuration, the electrical generator fuselage with award fan rotor and constitute one whole (but the flabellum part is a detouchable with the electrical generator body) is installed, except that some and the extraneous bonded assembly terminal reserved, the end of a thread, its complete machine should be able to firmly be installed on the car body, and installation or removal should be easy to; 2. the coil apparatus formed by pure iron-soft magnetic substance and excitation coil of the stator N of this machine, S pole field, in iron core, set up magnetic field behind the coil electricity, and this magnetic field can not continue to keep after the outage, concrete parts such as coil turn, size of current, brush, data and method, can use contemporary motor and manufacture in addition normative choice of cooking technique, this paper does not lay down hard and fast rule and special the proposition; 3, rotor can not be too heavy, otherwise, resistance when meeting increase train is advanced, with the train running speed is that 50km/h is a fundamental point, design rotor, especially when train gait of march when reaching 120kg/h or 300kg/h, the relation between total power consumption strength of its coil power supply amount and motor quantum of output and institute's electricity supply and use equipment, intelligent generating is accomplished in addition necessary strictness control as far as possible.Rotor is connected with the pivot shaft bolster of stator by an axle rod, prolongation place of spool rod simultaneously also connection awards fan rotor, can be at any time Assembly ﹠Disassembly easily.In order to make rotor obtain bigger propulsive effort, if the load of train allows, also can install additional again one or many fans award fan rotor, to obtain better driving effect.4. the diameter of awarding fan rotor should be 1-2 a times of root diameter, adopt the diameter that can suitably reduce flabellum when organizing flabellum more, the installing space that minimizing is taken like this, award fan rotor general one group on three leaves of selecting, also can be leafy, every leaf is from the center-point to the top end part widens shape gradually, to catch more energy, two kinds of different colors all will be coated in the two sides of whole flabellum, are adapted to maintenance and monitoring, award the fan rotor outside and should install Safety hood additional; 5. dispersing of electrical generator self heat is that the wind-force that brings by utilizing in the train operation reaches natural heat dissipation, reserves heat-dissipation passage, air port in advance on fairing, prevents rainwater and installs lightning protection, damping, noise abatement equipment additional but will take into account.Illustrate: because suitable proven technique is all arranged on dynamo theory and manufacturing technology now, above-mentioned about dynamo theory involved in the present invention and manufacturing technology and requirement, in actual application, should select and adopt the theory that has advance more to make, this paper do too much detailed description for saving length.

Two. train carries the selection of Idiotype electrical generator installation position:

1. general first-selected train underframe bottom, train bottom and rail (road surface) generally have the free space of 450mm, select suitable position that the electrical generator of distortion is adorned thereon, complete machine takes up space should be in the height space below the 350mm (calculating for the most outstanding part with this machine flabellum), only to be processed good, can not influence traffic safety.The advantage that is installed in the bottom is certain disguise, and the snow of can taking shelter from the rain does not affect the appearance again.Adopt the condition precedent of the method to be: 1. have available enough spaces; 2. in the exquisiteness, the extra-thin design that guarantee on the electrical generator production capacity basis; Each parts of electrical generator must have durability; Award fan rotor size, how much depend on available space;

2. also can be chosen in (top) portion of going up of train, adopt Idiotype electrical generator complete machine direct mount, inlay or the method on the roof that is embedded in partly, because the solid space of installing is bigger than preceding a kind of method, available condition is more.No matter adopt which kind of installation method, the stream line pattern of its complete machine must be complementary with car body and comprise color, and the parts of noise-decreasing must be very effective, and the electrical generator heat dissipation channel must be smooth and easy.Adopt when partly or entirely the electrical generator body being embedded in the method for car body, its part of awarding fan rotor optionally will reserve the passage for its rotation in car body, and various connections are reliability and durability;

3. the selection of above-mentioned installation site is at the railway transport of passengers train, as for the train of other delivery function such as goods train or truck tanker, this equipment is installed will specifically treat as the case may be, and this paper does not describe in detail.

Three. train carries the Idiotype electrical generator installs quantity:

The factor that quantity is installed in decision mainly contains 2 points: though 1. huge train can produce stronger air movement when operation reaches certain speed, but electrical generator is resistance factor after all, therefore, the size of its flabellum is selected very important, requires as long as should reach certain electrogenesis amount in line with the rotative speed that can drive rotor.2. if the electrical generator of manufacturing is excessive, the required train wind energy of its unit flabellum is just big, and therefore, it is longer that this paper advocates the relative transverse width of electrical generator self, as can be in the 1000-1200rmm scope; And himself relative thickness should be as far as possible little, and it is little that shared spatial altitude is tried one's best; Rotor, stator, award parts match rigorous and scientifics such as fan rotor; Watch outside electrical generator, flabellum is in the position of the both sides of electrical generator, and complete machine has Compact, exquisite careful characteristics.The selection of complete engine set installation quantity:

When A. selecting train bottom vehicle frame installation method: the relative train of beneath free space of train head is few possibly, generally the 1-2 platform can be installed, train then each joint all can be installed, and can install 2 simultaneously in the middle of the train, spacing is beyond the 1000mm, and two can be installed 1 again and be got final product; When B. selecting train top installation method: the top is optional position behind the motorcoach train head, when being installed on any headstock, all, accomplish when driving can not produce obstruction or interference with the existing electric power system of train self no matter any situation occurs away from train original supply line and equipment.Each joint two, compartment of train is first-selected position, can install 2 simultaneously respectively, and spacing is beyond the 1000mm, decides according to circumstances in the middle of the train.For example: according to the sequence marshalling of motor-car, calculate with row 8 joints, 20 this Idiotype electrical generators can be installed at least, the terminal of its output is together in series, gather together, unified carrying out such as technical finesse measures such as voltage stabilizing, rectifications used as aspects such as illumination, air-conditioning, heating, offices for train self at last.C. the installation at other positions of train and goods train, extraordinary train etc., its installation should be looked particular case and specifically treat, and this paper does not do special version.

Four. the arrangement of full train power supply and using electricity system:

A. power supply: in adopting the transmission process of this electrical generator, the 1. power supply system of train: still keep its original system design arrangement.Electric energy of the present invention is not recommended as the power system electricity consumption; 2. the non-power system power supply of train: before this electrical generator enters mode of operation, when also being the following speed of 40km/h, train can still be continued to use its original design power program, more than the 40km/h particularly train enter 60km/h when above, electric power energy of the present invention will enter optimal production capacity state, especially carries out under the running state of long distance or " cruising " speed at train.This just needs to be equipped with special electricity consumption and transforms computer system, need carry out intelligentized allotment by the running state and the electricity consumption of train at that time, under the precondition that does not influence consumer work, arbitrarily, Switching power timely, by the power supply of power supply order coupling, reach best effect.3. with regard to the electric power system of train, also can be with the power supply source of train as two cover systems: the primal system that a part is had by oneself for train, a part be generator powered of the present invention system.

B. electricity consumption: the train head is except that carrying out a whole set of electricity consumption original scheme that originally had, and the electric power that the present invention produced is mainly used in aspects such as 1. illuminations, heating, drinking water boiler, communication, office, and promptly all the electricity consumption departments outside the power system all can relate to; 2. if simplify this " transducing electric power " using method of sending by train, then directly the electric power that this electrical generator produced is passed through a series of equipment, it is delivered directly in the extraneous electrical network, become new power source.Because this machine generating capacity is limited, electric network influencing is limited to external world, and the present invention is not as main purpose.

It more than is technical scheme of the present invention.

Railway and train energy-conversion technique and current railway applications technology are had a mind to the comparison of effect:

The application engineering of current railway is a huge application system engineering, and available potential and chance that investment is big, scale is big, transport power is big, exist are also many.From the railway invention so far, human application for railway particularly should remain the more extensive state that is in the application facet of the energy, particularly on the various all kinds of problems that cause now because of energy problem, more and more sharp-pointed mention human in face of.Simultaneously, we by by coal-fired to fuel oil again in the process of electric power as the railway power resources, using the means of various technology and the degree of becoming more meticulous of energy source use is progressive gradually process.But,, energy savings, make full use of the energy and then reduce environmental pollution, reduce emission of carbon-dioxide and especially seem especially outstanding important so that to save fossil energy be homophony and be in the current society of developing direction with the green regenerative energy sources.The applied energy of rows of cars mainly just has two: the one, and power driven is to the dependence of the energy, and the 2nd, train self is for the use of the energy.The present invention and current particularly comparison on the use problem of train self electricity consumption of railway applications technology, railway power supply application model before having broken through, strengthened the green of train electricity consumption, though this is middle according to the energy conservation and transformation law science, the awarding fan rotor and can form a kind of resistance factor of this electrical generator with respect to train operation, but in practice, the interests that air flows is brought that kinetic energy caused that train is huge compare, utilization is very important, in objective still more, our train usually can not be accomplished " oepration at full load ".Adopt the present invention when certain speed is arrived in train operation, can make the application facet of rows of cars, reduced its undue dependence, the advantage of certain " self-sufficiency through productive labour " is arranged for the energy beyond the train at the energy; Favourable reduction the railway operation cost; Simultaneously, also reduced emission of carbon-dioxide accordingly and reduced the use of fossil energy, than current train operation pattern realized half greening operation basically, to full greening running technology near major step.

The specific embodiment:

Enforcement of the present invention will relate to railway engineering subject, electric power subject, mechanics particularly wind-force, wind-tunnel theory and motor manufacturing and production aspects.Manufacture view at dynamo theory and electrical generator, the science and technology circle has objectively possessed advantage, application engineering is very ripe, especially about various electrical generators the reaching its maturity and widespread use of manufacturing technology of aerogenerator particularly, makes the implementation barrier of present technique seem few.Mainly be to confirm through the further enforcement of correlation technique department, choice to developing direction, especially the expansion of Zhong Guo high speed railway plan, feasibility condition has been created in the enforcement that is all present technique, use present technique will make railway especially the application engineering of high speed railway aspect be able to further improve and optimize; Can make that also railway obtains effectively and significantly improving on the operating cost problem; The more important thing is that railway has certain initiative of knowing clearly on the problem of carbon dioxide and reduction of discharging, significantly progressive, meet the world for environment requirement; In addition, also can drive motor manufacturing enterprise, increase new varieties again in the wind-driven generator field of making.Railroad train takes the lead in realizing that the basic condition of the green operation of part is that other industry is incomparable.

The equipment of present technique and infusion of financial resources can be very not big yet.
