Description

The docking system of train and station passage

The application is the divisional application of application number 201080010573.2, March 3 2010 applying date, priority date on March 3rd, 2009, denomination of invention " oxygen enrichment low pressure pipeline permanent magnetic drive wheel track magnetic floats vehicle-subgrade system ".

Technical field

The present invention relates to low pressure pipeline Sealing Technology and permanent magnet suspension vehicle technical field, be specifically related to docking system and the floating vehicle-subgrade system of permanent magnetic drive wheel track magnetic of the separating system of the low pressure pipeline of bullet train, train and station passage.

Background technology

Wheel-rail train relies on wheel supporting, guiding and driving, train driving is dependent on the adhesion between wheel and track and drives, the adhesion of wheel and track is as squandered, and the probability of the more high contact of speed is more little, and the adhesion coefficient of wheel and track is progressively declining with the raising of speed.When running at a low speed, air drag is little of ignoring, and main resistance shows wheel and interorbital resistance to rolling.In running at high speed, square being directly proportional of air drag and speed, speed improves air drag and enlarges markedly, speed reaches main resistance after to a certain extent and shows air drag, and the driving force that sticks together of the wheel of wheel-rail train and track is progressively declining with the raising of speed, there is a limit velocity balanced each other eventually.Wheel-rail train is by the impact of wheel with the adhesion coefficient of track, the highest current economic pace is at 360 km, speed-raising will become highly difficult again, lower adhesion coefficient becomes very little at a high speed, motor driving force is also of no avail greatly again, and slipping degree increases, and energy consumption consumes huge, limiting the speed of wheel-rail train, the economic speed per hour of the limit is no more than 400 kilometers.Why aircraft can exceed that 800 kilometers of speed per hour flights, and can hover in meters altitude, have benefited under 6000 to 18000 meters of high-altitudes, air more up becomes more thin, more more little toward altitude air density, flight resistance also diminishes therewith, and therefore same speed is more more energy-conservation than ground driving in high-altitude flight.So all first flying toward high-altitude after taking off, due to the reduction of flight resistance, the speed that aircraft reaches can be higher.If the environment createing similar aircraft high-altitude flight on ground just can save substantial amounts of energy, and speed can reach more than the speed of aircraft.Before half a century, people just have contemplated that certain vacuum is pumped in the inside at the pipeline that infrastructure is airtight, and air drag just becomes fairly small, and driving will be very energy-conservation in this environment.But hole in underground, then make low pressure pipeline, cost meeting prohibitively high, and in underground once break down and being difficult to escape.One mentions race bullet train in low pressure pipeline, and people may feel that very dangerous at once, because the air in low pressure pipeline is quite few, people is inside difficult to survival.Actually we take advantage of the external environment condition gone by air to be exactly this lower pressure environment, the Concorde aircraft in 15000 meters of-18000 meters of high-altitudes that such as flies has reached the supersonic speed of 2000 kilometers of speed per hours, the atmospheric pressure of aircraft exterior only has about the 1/10-1/5 of ground standard air, the low extreme severe cold reaching less than-40 DEG C of temperature, people are still safe and sound inside aircraft, just it is because people and aircraft is made very tightly insulation, the complete facility of guaranteed passenger safety, aircraft has been acknowledged as the vehicles that safety coefficient is the highest.So we are at the surface construction lower pressure environment similar to aircraft ambient atmosphere, and temperature is room temperature rather than severe cold low temperature, even if safety devices are the same with aircraft, and also can be safer than aircraft.Once occur unexpected in low pressure pipeline, people can also run out escape in train.But pressure only has the air in the low pressure pipeline of the 1/10-1/4 of standard atmosphere very thin, if people go in pipeline still can anoxia asphyxia and threat to life, still suffer from potential safety hazard.

nullAfter current people imagine train bus stop, the mode of the upper Train of passenger mainly adopts in low pressure pipeline to arrange isolation gate and increase the mode of depressurization transitions pipeline and passes in and out train，Namely after train arrives at bus stop，Whole joint train is enclosed in the closed conduit being longer than train by the isolation gate of rear and front end，Long pipeline first becomes pressure pipeline，Then in pipeline, air is passed into，The several minutes time is needed when arriving normal atmosphere，After supercharging transition conduit and ambient atmosphere balance, opening conduits station passage door and train door start upper and lower passenger again，After passenger all passes in and out compartment，Close train door and pipeline platform access door，Start the airtight long pipeline evacuation to train place again，Long pipeline becomes again depressurization transitions pipeline，The vacuum state being pumped into requirement needs the dozens of minutes time，Two ends isolation gate is opened again after identical with pressure in low pressure pipeline，Train just sails low pressure pipeline into and travels to the next stop.This series of actions needs the time of dozens of minutes, similar with the aircraft takeoffs and landings waiting time, makes the quick advantage of maglev high speed play not out.People never resolve magnetic suspended railway and existing railwayed versatility and compatibling problem for a long time, the wheel-rail train that is can not pass through on magnetic-levitation, can not be passed through on the track of wheel-rail train magnetic suspension train, existing wheel-rail train needs transfer magnetic suspension train through magnetic-levitation, wheel-rail train is gained again through wheel track rail track, very inconvenient.Which also limits the popularization and application of magnetic suspension train technology.Conventional wheel-rail train is after speed-raising, air drag increases, advance resistance increases, the increase of train energy consumption increases with velocity squared, this certainly will increase train operation cost, cause train speed raising rear car ticket rise in price clearly, this departmental cost have to turn be added on the body of passenger, high admission fee is acceptant for white collar class and businessman, it is added burden for the high admission fee of ordinary people, what most ordinary peoples were concerned about is not save several hours, what more take a fancy to is admission fee height, bullet train benefited party after speed-raising is the crowd often taking advantage of and making aircraft, most common people are not substantially benefited.The high admission fee that train brings at high speed is not desired.It is solve the more effective approach of bullet train operating cost that Erecting and improving low pressure pipeline system reduces the topmost air drag of bullet train, and problem is very necessary to overcome existing by the station car docking system therefore developing a kind of novel low pressure pipeline.

Summary of the invention

In view of the problem existing for prior art, it is contemplated that overcome the weak point existed in above-mentioned technology, thering is provided the docking system of a kind of train and station passage, the magnetic suspension train of the low pressure pipeline technology that it adopts is than the high-speed locomotive energy-conservation more than 80% adopting low pressure pipeline technology；Maglev low friction advantage is made to seem especially prominent, the present invention adopt the high-speed maglev train of this low pressure pipeline technology can significantly save the energy, safe and reliable, only need the time of tens seconds just can realize train and station passage rapid abutting joint, personnel can quickly go up Train and utilize existing wheel track track and turnout as the positioning track of magnetic suspension train and to become rail system, the construction cost making magnetic-levitation is lower, and with existing to take turns rail railway completely compatible.

1. it is more much lower than adopting subterranean tunnel formula low pressure pipeline mode not only cost to adopt ground or overhead system low pressure pipeline mode, and it is safer, occur if any abnormal conditions, ground or overhead system low pressure pipeline safe ventilation plug can be opened, rapidly and atmosphere, passenger can safe escape pipeline for low pressure pipeline.More much more secure almost without hope of surviving than aircraft altitude.

2. magnetic-levitation train adopts circumferential type structure will not derail and overturn forever, likely derails to overturn than the open Wheeltrack structure of high-speed locomotive and wants high safety.

3. low pressure pipeline is significantly high to train and passenger safety protective action, even if the destroyed gas leakage of low pressure pipeline, gas in pipelines pressure and car resistance can only be increased, train and personnel will not be caused any harm, so preventing the safety destroying and resisting terrorist attacks higher.

4. more safer than the upper low low temperature environment at aircraft place.Except being equipped with the safety devices such as QI invigorating equipment, oxygen face mask in compartment, the temperature of low pressure pipeline is identical with surface air rather than severe cold low temperature, once occur accident in low pressure pipeline, people out will not be subject to the injury of low temperature in train, more safer than high-altitude.The pressure of high altitude environment only has the 1/10-1/4 of standard atmosphere, and oxygen content drops to the 1/10-1/4 of ground environment therewith, and people still can be in the environment of anoxia, there is potential safety hazard.Although pressure only has the 1/10-1/4 of standard atmosphere in low pressure pipeline, but oxygen content enriches in pipeline, oxygen content is basic identical with ground oxygen content, people are even at this environment, without anoxia, it is possible to take action in low pressure pipeline freely, find passway for escaping, open gas valve and safety door and leave low pressure pipeline safely, thus can be safer than aircraft.

5. the setting filling air bag makes the transition conduit exhaust decompression time shorten tens times even tens times than usual mode, and train can be greatly shortened by the time of transition conduit, improves the turnover efficiency of transition conduit.In evacuation procedure, pressure at expulsion difference is only small, almost carries out at ambient pressure, reduces emptying energy to greatest extent, is beneficial to energy-saving and emission-reduction.

6. station car docking system makes passenger getting on/off speed faster.The present invention can realize, in low pressure pipeline after train bus stop, opening train door in tens seconds, after personnel get on or off the bus, is quickly evacuated to low pressure and closes train door, leave station and run at high speed in tens seconds.Whole get on or off the bus time and common train time of getting on or off the bus only extends tens seconds, is barely affected for the total time of long-distance travel, and all the other situations are nearly identical, and passenger does not have the sensation of difference.

7. retractable door can retract near low pressure pipeline wall, strengthens gusset without departing from pipeline, passes through at a high speed without influence on train.Need not bus stop time, train can more than 800 kilometers speed per hours quickly through by way of city, it is not necessary within speed limit to 200 kilometers speed per hour, train average speed per hour will not be made to be affected.

8. retractable door adopts permanent magnetic chuck locking, and coupling mechanism force, not by Electric control, can be avoided locking, during unexpected power-off, the gas leakage decompression problem lost efficacy and cause.The region area scope of locking is relatively big, and train stop position is without requiring very accurate, as long as the outside that the position of retractable door covers on train door or low pressure pipeline access door can reliable lock sealing.The surface of train or heavy connection of pipe need not highlight locking mechanism in surface, set place outdoors, it is possible to be made very smooth, advantageously reduce the air drag of driving.

9. significantly energy-conservation.Under the isolation of seal closure, train air drag in low-voltage space environment is reduced to the 0.1-0.22 of near-earth dense atmosphere environment, eliminates the air drag of 78%-90%.The height of vacuum in pipeline need not be worried additionally for the bullet train transporting goods, it is possible to adopt 1/100 pressure below of standard atmosphere, save the air drag of 99%.Permanent magnet suspension system eliminates again the frictional resistance of more than the 90 of train, Linear Synchronous permanent-magnet drive system makes again train and interorbital transmission efficiency more than 98%, there's almost no electromagnetic resistance and eddy resistance, the energy consumption adopting the magnetic suspension train of low pressure pipeline technology only adopts 1/5th of the high-speed locomotive energy consumption of low pressure pipeline technology, less than 1/10th of aircraft energy consumption, save overwhelming majority energy.Railway occupies important proportion in the development of the national economy, and the energy-conservation realization to whole nation target for energy-saving and emission-reduction of railway transportation has great importance.

10. freight substantially reduces.Bullet train account for major part proportion air drag be significantly reduced after, running resistance substantially reduces, and operating cost is greatly lowered, and brings the obvious room for price-cut of train fare, the common people in the whole nation not only can shorten the journey time, moreover it is possible to obtains admission fee and reduces the material benefit brought.Therefore long haul cost also substantially reduces, and this is to reducing logistics cost, it is prevented that price rise, strengthens international manufacturing cost competitive advantage and has realistic meaning.

11. driving force is big, climbing capacity is strong, can climb up 30% with upgrade.Acceleration ratio wheel track is big, can shorten acceleration time and braking distance.

12. the speed of service is high.Employing linear permanent magnet driving system drives, do not affected by wheel track track adhesion coefficient, train air drag in low pressure pipeline environment only has 0.1-0.22 times of near-earth dense atmosphere, driving force improves a lot and running resistance is significantly reducing, magnetic-levitation train can realize running at high speed forever.Adopting the magnetic-levitation train of Linear Synchronous permanent-magnet drive system, the speed of service is up to 800-1000 kilometer/hour.Can be furthered the city distance with city, even country with country further.

13. the rail guide-localization rigidity adopting wheel track is big, stop the electromagnetic suspension guiding low weakness substantially rocked at high speeds of rigidity, run more steady, take advantage of do comfortable.

14. adopt permanent magnet suspension to overcome the deadweight of more than 90%, wheel is slight with the mechanical friction of rail, and the mechanical life of moving component is obviously prolonged.Maintenance cost can be reduced.

15. train marshalling list length arbitrarily increases and decreases, rate of traffic flow can regulate and control according to the actual volume of the flow of passengers, and running interval is minimum up to 3 minutes, it is possible to adapts to different traffic requirements.

16. bearing capacity is existing wheel-rail train and the summation of magnetic suspension train transport power, overload surplus is very big.Permanent magnet suspension track, once overload, also has the surplus being equivalent to wheel track track bearing capacity, adapts to the situation that the peak period volume of the flow of passengers is increased sharply.

17. owing to permanent magnet driver and interorbital magnetic force are very big, unless emergency, braking can all rely on permanent magnetic drive power regenerative braking, without wasting the energy by eddy current deceleration or mechanical brake at high speeds, save braking energy to greatest extent, as conventional wheel-rail train, no longer supplement the deficiency of wheel adhesion coefficient by mechanical friction braking.

18. line construction comprehensive cost is low.Whole track need not drive coil, control point power station on the way need not be built, also without complicated control electric system, the construction of low pressure pipeline makes to be no longer necessary to along the line build guard rail, also the construction of electric pole along the line can be saved, Along Railway construction cost reduces, and personnel's maintenance cost reduces.Owing to transmission magnetic gap is big, on track, the machining accuracy of helical stator core need not be significantly high, so low cost of manufacture.The cost building low pressure pipeline part only accounts for the only small ratio of overall line cost, these make the integrated cost of wheel track magnetic suspended railway construction that linear permanent-magnet drives drop to suitable with High-speed Wheel/Rail construction cost, and this will greatly promote the universal of magnetic suspension train technology and promote.

19. all-weather travels.There is the shielding of seal closure outside high-speed track, it is possible to prevent boisterous impact, make railway be no longer influenced by the obstruct of snowstorm, hail, ice rain, Sandstorm.Thunderstorm foggy weather will not be run into as aircraft must ground, wind and waves weather will not be run into as steamer must pull in shore to suspend, will not as automobile, passenger vehicle catches in a blizzard, typhoon, rain, foggy weather must reduce speeds or close highway to have a clear superiority in.Can accomplish that all-weather travels, stopped by neither wind or rain.

20. noiselessness.Have the shielding of seal closure outside high-speed track, it is possible to intercept sound unofficial biography, even if train with more than 800 kilometers speed per hours quickly through city, still quiet to external world.Within speed limit to 200 kilometers speed per hour, train average speed per hour need not will not being made to be affected, without the phenomenon causing noise to disturb residents, this is to preventing vehicle from the life of surrounding resident being had undesirable effect, and protection people's health has very real meaning.

21. electromagnetic-radiation-free.Seal closure adopts cold-rolled steel sheet with low cost to make, and has the shielding of steel seal closure, it is possible to shield electromagnetic to external radiation outside high-speed track, it is also possible to the magnetic field shielding of internal kicker magnet to identical with magnetic field of the earth.Make surrounding resident without the trouble and worry of Electromagnetic Interference.

22. zero-emission.Use driven by power, it is possible to not against oil and coal, it does not have toxic emission, without air pollution.Environmentally friendly three-dimensional magnetic suspension traffic system can be built into.

23. the positioning and guiding system of magnetic suspension train adopts the guiding rail of conventional wheel track track, the wheel track magnetic-levitation of compatibility is formed after the outside of guiding rail or inner side arrange permanent-magnet drive system and permanent magnet suspension system, it is truly realized magnetic suspended railway and existing railwayed versatility and compatibility, can be passed through on wheel track magnetic-levitation wheel-rail train, and can pass through again magnetic suspension train.Some wheel track track existing can be transformed by treatment in accordance with local conditions by these organization plans, it is also possible to utilizes existing wheel track track switch, and the Line technology of the existing china railway netting twine built is transformed and provided practicable track reference scheme by this.

24. low pressure pipeline internal pressure controls the lower pressure environment of about the 1/10-1/4 at normal atmosphere, it is possible to fully ensure that the safety of passenger in low pressure pipeline.People's blood under the low pressure lower than about the 1/20 of standard atmosphere can seethe with excitement and dead immediately, so being maintained above 1/10 normal atmosphere can compare safety, can reduce by the air drag of 90% at this pressure, saving the huge driving energy.

25. be filled with the oxygen of oxygen content 80%-99% in low pressure pipeline.Ignoring the few carbon dioxide of content in air and noble gas, content of oxygen in air is about 22% in simple terms, and nitrogen content is about 78%, and human life activity is not required in that by this nitrogen of 78%, but significantly increases vehicle and aircraft travels energy consumption.Wherein the oxygen of content 22% is only necessary to physical activity.If the nitrogen in pipeline air is taken out, and being only left oxygen, even if pressure have dropped 78%, in pipeline, the per unit volume concentration of oxygen does not still change.The biological time that can survive longer under such circumstances, increase the chance that escape is rescued.2008 Beijing Olympic Torch is at Mountain Everest successful ignition of height above sea level 8844.43 meters; the atmospheric pressure on Mount Everest top only has about 30KPa; temperature on average is between-40 DEG C to-50 DEG C; oxygen content only has about 6.6%; climbers still can be engaged in the weight muscle power mountaineering of complexity; sufficing to show that oxygen content is under the environment of the room temperature oxygen enrichment low pressure pipeline of 10%-22%, people remain able to normal activity.

When 26. train is entered into low pressure pipeline system by the ground rail of normal atmospheric environment except adopting the mode that isolation gate and increasing depressurization transitions pipeline are set inside and outside low pressure pipeline to pass in and out the mode of train, tube wall in transition conduit is arranged around filling air bag, and the gas emptying time of transition conduit can shorten tens times even tens times.Train by transition conduit in the short time, can pass in and out low pressure pipeline.Train is once enter in very long low pressure pipeline system and being in the upper low environment of similar aircraft flight, and running resistance is substantially reduced.Soft air bag 68 of filling is adapted to the profile of the interior different trains of transition conduit, is expelled from the gas of transition conduit to greatest extent.In exhaust decompression process, suction pressure is almost that long pressure carries out, and sunlight limits can reduce exhaust energy.

27. train adopts platform and car door rapid abutting joint system when driving to each parking website in low pressure pipeline system, make to transfer in the small space between docking car door more than the huge transition conduit of whole train, need the volume-diminished up to ten thousand times of emptying, after car door rapid abutting joint, the air in space between docking car door can quickly be pumped into the lower pressure environment being equivalent to near-earth air about 1/10 to 1/4, it is also possible to was filled with gases at high pressure within several seconds kind time and reaches normal atmosphere.The operating process such as quick open/close door, inflation or evacuation all only need the time of tens seconds just can realize train and platform rapid abutting joint, and personnel can quickly go up Train.

28. adopt the rail positioning track as magnetic suspension train of wheel rail railway, by suspension railway with driving track according to more reasonably arrangement, existing wheel track rail system all can be remained, existing wheel track turnout can be utilized as the change rail system of magnetic-levitation, the construction cost making magnetic-levitation is lower, and with existing to take turns rail railway completely compatible.

29. spatial transition 23 was connected with vacuum chamber with valve also by communicating pipe.The volume of vacuum chamber is far longer than spatial transition 23, it it is 100 times to more than 1000 times of spatial transition 23, vacuum chamber is evacuated in advance, the pressure of vacuum chamber reaches about 1-10Pa, after spatial transition 23 and vacuum chamber, gas in spatial transition 23 is rapidly to vacuum chamber internal diffusion, and the pressure of spatial transition 23 is rapidly decreased to the 1/10 ~ 1/5 of standard atmosphere.Vacuum chamber can be multiple, sequentially opens evacuation, and vacuum can reach higher, and the pressure of spatial transition 23 can be reduced to the 1/100-1/1000 of standard atmosphere.
