Description

Wheeltrack magnetic suspension train by permanent magnetism driving in low pressure oxygen-enriched pipeline

Specification

Oxygen-enriched 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, and in particular to separating system, the docking system of train and station passage and the permanent magnetic drive wheel track magnetic of the low pressure pipeline of bullet train float vehicle-subgrade system.

Background technology

Wheel-rail train is by wheel supporting, guiding and drives, train driving is by the adhesion driving between wheel and track, the adhesion of wheel and track is as squandering, and the probability of the higher contact of speed is smaller, 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 small to that can ignore, and main resistance shows the rolling resistance of wheel and interorbital.In running at high speed, air drag and speed square are directly proportional, speed improves air drag and significantly increased, main resistance shows air drag after speed reaches to a certain extent, and the wheel of wheel-rail train and the driving force of sticking together of track are progressively declining with the raising of speed, there is a limit velocity balanced each other eventually.Wheel-rail train is influenceed by the adhesion coefficient of wheel and track, current highest economic pace is in 360 kms, raising speed again will become highly difficult, lower adhesion coefficient becomes very small at a high speed, motor driving force is also of no avail greatly again, and slipping degree increase, energy consumption consumption is huge, the speed of wheel-rail train is limited, 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 thinner, it is more smaller toward altitude air density, flight resistance also diminishes therewith, therefore same speed is more saved in high-altitude flight than ground driving.So all first flying after taking off toward high-altitude, due to the reduction of flight resistance, the speed that aircraft reaches can be higher.If that can save substantial amounts of energy if the environment of similar aircraft high-altitude flight is createed on ground, and speed can reach more than the speed of aircraft.People are just had contemplated that in the closed pipeline of infrastructure before half a century, and certain vacuum is pumped into the inside, and air drag just becomes fairly small, and driving in this environment will be saved very much.But holed in underground, then make low pressure pipeline, cost can be prohibitively high, and it is difficult escape once to be broken down in underground.One mentions bullet train is run 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 difficult inside survival.It is exactly this environment under low pressure that actually we, which multiply the external environment condition gone by air, the Concorde aircraft in 15000 meters of -18000 meters of high-altitudes that for example flies has reached the supersonic speed of 2000 kilometers of speed per hours, the atmospheric pressure of aircraft exterior only has 1/10-1/5 of ground standard air or so, the low extreme severe cold for reaching less than -40 °C of temperature, people are still safe and sound inside aircraft, exactly because aircraft is made very tight insulation by people, the complete facility of guaranteed passenger safety, aircraft has been acknowledged as the safety coefficient highest vehicles.So we are in the surface construction environment under low pressure similar to aircraft ambient atmosphere, and temperature is normal temperature rather than severe cold low temperature, also can be safer than aircraft even if safety devices are as aircraft.Once occurring in low pressure pipeline unexpected, people can also run out escape out of train.But pressure only has the air in the 1/10-1/4 of normal atmosphere low pressure pipeline very thin, if people go in pipeline still can anoxia asphyxia and threat to life, still suffer from potential safety hazard.

The mode of the upper Train of passenger mainly passes in and out train by the way of door between setting isolation in low pressure pipeline and increasing depressurization transitions pipeline after current people's imagination train bus stop, i.e. train is arrived at after bus stop, whole section train is enclosed in the closed conduit for being longer than train by the isolation gate of rear and front end, long pipeline first becomes pressure pipeline, then air is passed through into pipeline, several minutes of times are needed when reaching standard atmospheric pressure, opening conduits station passage door and train again is pressurized after transition conduit is balanced with ambient atmosphere Door start above and below passenger, passenger is all passed in and out behind compartment, close train door and pipeline platform access door, start to vacuumize the closed long pipeline where train again, long pipeline becomes depressurization transitions pipeline again, being pumped into the vacuum state of requirement needs the dozens of minutes time, it is identical with pressure in low pressure pipeline after open two ends isolation gate again, train just drives into low pressure pipeline and travelled to the next stop.This series of actions needs the time of dozens of minutes, with the aircraft takeoffs and landings stand-by period almost, plays the quick advantage of maglev high speed and does not come out.People, which never have, for a long time resolves magnetic suspended railway and existing railwayed versatility and compatibling problem, that is the wheel-rail train that can not be passed through on magnetic-levitation, can not pass through magnetic suspension train on the track of wheel-rail train, existing wheel-rail train needs to change to magnetic suspension train by magnetic-levitation, wheel-rail train is gained again by wheel track rail track, it is very inconvenient.Which also limits the popularization and application of magnetic suspension train technology.Conventional wheel-rail train is after speed-raising, air drag increase, 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 apparent, this departmental cost has to turn to be added on the body of passenger, high admission fee is acceptant for white collar and businessman, high admission fee is added burden for ordinary people, what most ordinary peoples were concerned about is not to save several hours, what is more taken a fancy to is admission fee height, bullet train benefited party after speed-raising is often to multiply the crowd for making aircraft, most common people, which do not have, to be substantially benefited.The high admission fee that train is brought at high speed is not desired.It is to solve the more effective approach of bullet train operating cost that Erecting and improving low pressure pipeline system, which reduces the topmost air drag of bullet train, therefore it is very necessary to problem to overcome existing to develop a kind of new oxygen-enriched low pressure pipeline permanent magnetic drive wheel track magnetic to float vehicle-subgrade system.

Compared with prior art, beneficial effects of the present invention are as follows：

There is the shielding of seal closure outside 1.1 high-speed tracks, can prevent flying bird from colliding bullet train, prevent the article of high value in track from losing, it is to avoid the crowded injures and deaths phenomenon fallen into track of personnel, seal closure is very safe equivalent to isolation railing.High-speed locomotive periphery certain distance is also required to construction and enclosed block and guard rail, so construction cost does not have significant difference.

1. using ground or overhead system low pressure pipeline mode ratio, using subterranean tunnel formula low pressure pipeline mode, not only cost is much lower, and it is safer, occur if any abnormal conditions, ground or overhead system low pressure pipeline safe ventilation plug can be opened, low pressure pipeline is communicated rapidly with air, and passenger can be with safe escape pipeline.Wish much more secure almost without surviving than aircraft altitude.

2. magnetic-levitation train will not be derailed and be overturned using circumferential type structure forever, Wheeltrack structure more open than high-speed locomotive, which is possible to derailing, overturns and wants high safety.

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

4. it is more safer than the upper low low temperature environment where aircraft.In addition to being equipped with the safety devices such as tonifying Qi equipment, oxygen mask in compartment, the temperature of low pressure pipeline is identical with surface air rather than severe cold low temperature, once occurring accident in low pressure pipeline, people will not out be injured out of train by low temperature, more safer than high-altitude.The pressure of high altitude environment only has the 1/10-1/4 of normal atmosphere, and oxygen content drops to the 1/10-1/4 of ground environment therewith, and people still can be in the environment of anoxic, there is potential safety hazard.Although pressure only has the 1/10-1/4 of normal atmosphere in low pressure pipeline, but oxygen content enriches in pipeline, oxygen content is substantially identical with ground oxygen content, people are even at this environment, also will not anoxic, can freely in low pressure pipeline take action, 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 of filling air bag makes the transition conduit exhaust decompression time want even tens times of short more than ten times of Shrink than usual mode, train can be short with big Shrink by the time of transition conduit, improves the turnover efficiency of transition conduit.Pressure at expulsion difference very little, is almost carried out at ambient pressure in evacuation procedure, to greatest extent reduction emptying energy, beneficial to energy-saving and emission-reduction.

6. station car docking system makes passenger getting on/off speed faster.In the achievable low pressure pipeline of the present invention after train bus stop, train door was opened in tens seconds, it is interior in tens seconds to be quickly evacuated to low pressure and close train door after personnel get on or off the bus, leave station and run at high speed.Whole get on or off the bus time and common train time of getting on or off the bus only extend tens seconds, are barely affected for the total time of long-distance travel, remaining situation is nearly identical, passenger does not have the sensation of difference.

7. Shrink Ke Hui Shrink of Shen are near low pressure pipeline wall, without departing from pipeline stiffener plate, do not interfere with train and pass through at a high speed.Do not need bus stop when, train can with more than 800 kilometers speed per hours quickly through by way of city, it is not necessary within speed limit to 200 kilometers of speed per hours, train average speed per hour will not be made to be affected.

8. Shen Shrink is using permanent magnetic chuck locking, coupling mechanism force can avoid locking failure during power-off suddenly and cause not by Electric control Gas leakage decompression problem.The region area scope of locking is larger, and train stop position is without requiring very accurate, as long as the outside that Shen Shrink position covers on train door or low pressure pipeline access door can reliable lock sealing.Surface need not protrude locking mechanism at set outdoors for the surface of train or heavy connection of pipe, can be made very smooth, advantageously reduce the air drag of driving.

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

10. freight is substantially reduced.Bullet train account for most of proportion air drag be significantly reduced after, running resistance is substantially reduced, and operating cost is greatly lowered, and brings the obvious room for price-cut of train fare, common people's Bu Dan Ke Yi Shrink short journey times in the whole nation, moreover it is possible to obtain the material benefit that admission fee reduction is brought.The also therefore substantially reduction of long haul cost, this prevents price rise to reduction logistics cost, and strengthening international manufacturing cost competitive advantage has realistic meaning.

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

12. the speed of service is high.Driven using linear permanent magnet driving system, do not influenceed by wheel track track adhesion coefficient, air drag of the train in low pressure pipeline environment only has 0.1-0.22 times of near-earth dense atmosphere, and driving force improves a lot and running resistance is being significantly reduced, and magnetic-levitation train can be realized and run at high speed forever.Using the magnetic-levitation train of Linear Synchronous permanent-magnet drive system, the speed of service is up to 800-1000 kilometers/hour.Can further be furthered city and city, even country and national distance.

13. it is big using the rail guide-localization rigidity of wheel track, prevent electromagnetic suspension and be oriented to the low weakness substantially rocked at high speeds of rigidity, operation is more steady, multiply and do comfortable.

14. overcoming more than 90% deadweight using permanent magnet suspension, the mechanical friction of wheel and rail is slight, 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, be adapted to different transport needs.

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

17. because the magnetic force of permanent magnet driver and interorbital is very big, except nonemergency, braking can be all by permanent magnetic drive power regenerative braking, without wasting the energy by vortex deceleration or mechanical brake at high speeds, braking energy is saved to greatest extent, brakes the deficiency of supplement wheel adhesion coefficient by mechanical friction no longer as conventional wheel-rail train.

18. line construction comprehensive cost low.Driving coil is not needed on whole track, control point power station on the way need not be built, also without complicated control apparatus system, the construction of low pressure pipeline no longer needs to build guard rail along making, also the construction of the electric pole along can saving, Along Railway construction cost is reduced, the reduction of personnel's maintenance cost.Because transmission magnetic gap is big, the machining accuracy of helical stator core need not be very high on track, so manufacturing cost is low.The cost for building low pressure pipeline part only accounts for whole The very little ratio of body line cost, these cause the integrated cost of the wheel track magnetic suspended railway construction of linear permanent-magnet driving drops to suitable with High-speed Wheel/Rail construction cost, and this will greatly promote the popularization and popularization of magnetic suspension train technology.

19. all-weather is travelled.There is the shielding of seal closure outside high-speed track, boisterous influence can be prevented, railway is no longer influenced by the barrier of snowstorm, hail, ice rain, Sandstorm.Thunderstorm foggy weather will not be run into as aircraft to ground, wind and waves weather will not be run into as steamer must pull in shore to suspend, and will not be caught in a blizzard as automobile, car, typhoon, rain, foggy weather must reduce speed traveling or closing highway will have a clear superiority.It can accomplish that all-weather is travelled, it is stopped by neither wind or rain.

20. it is noiseless.Have the shielding of seal closure outside high-speed track, the unofficial biography of sound can be obstructed, though train with more than 800 kilometers speed per hours quickly through city, it is still quiet to external world.Need not speed limit within 200 kilometers of speed per hours, train average speed per hour will not be made to be affected, the phenomenon that noise disturbs residents is not resulted in yet, this is to preventing life of the vehicle to surrounding resident from having undesirable effect, and protection people's health has very real meaning.

21. electromagnetic-radiation-free.Seal closure is made using cold-rolled steel sheet with low cost, the shielding for having steel seal closure outside high-speed track, can shield electromagnetic wave to external radiation, can also be the magnetic field shielding of internal kicker magnet to identical with magnetic field of the earth.Make trouble and worry of the surrounding resident without Electromagnetic Interference.

22. zero-emission., can be not against oil and coal, without waste gas discharge, no air pollution using driven by power.Environmentally friendly three-dimensional magnetic suspension traffic system can be built into.

23. the positioning and guiding system of magnetic suspension train is using the guiding rail of conventional wheel track track, the wheel track magnetic-levitation that compatibility is constituted after permanent-magnet drive system and permanent magnet suspension system is set in the outside or inner side for being oriented to rail, it is truly realized magnetic suspended railway and existing railwayed versatility and compatibility, can pass through wheel-rail train on wheel track magnetic-levitation, and the magnetic suspension train that can pass through.These organization plans can suit measures to local conditions to transform existing some wheel track tracks, can also utilize existing wheel track track switch, and this Line technology transformation to the existing china railway netting twine for having built completion provides practicable track reference scheme.

24. low pressure pipeline internal pressure controls the environment under low pressure in the 1/10-1/4 of standard atmospheric pressure or so, the safety of passenger in low pressure pipeline can be fully ensured that.People's blood under the low pressure less than 1/20 or so of normal atmosphere can seethe with excitement and dead immediately, thus be maintained above 1/10 standard atmospheric pressure can relatively safety, can reduce by 90% air drag at this pressure, save the huge driving energy.

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

When 26. train enters low pressure pipeline system by the ground rail of normal atmospheric environment in addition to passing in and out the mode of train by the way of door between the setting isolation inside and outside low pressure pipeline and increasing depressurization transitions pipeline, filling air bag, even tens times of short more than ten times of the gas emptying time Ke Yi Shrink of transition conduit are set around the tube wall of transition conduit.Train can with the short time by transition conduit, Pass in and out low pressure pipeline.Train is in the upper low environment of similar aircraft flight once entering in very long low pressure pipeline system, and running resistance is substantially reduced.Soft filling air bag 68 is adapted to the profile of different trains in transition conduit, and the gas of transition conduit is expelled to greatest extent.During exhaust decompression, suction pressure is almost long pressure and carried out, and exhaust energy can be reduced to greatest extent.

27. train uses platform and car door rapid abutting joint system when each parking website is driven in low pressure pipeline system, the huge transition conduit made more than whole train is transferred in the small space between docking car door, need the Ti Ji Shrink of emptying small up to ten thousand times, after car door rapid abutting joint, the air in space between docking car door can be pumped into the environment under low pressure equivalent to near-earth air 1/10 to 1/4 or so quickly, can also be filled with gases at high pressure within several seconds kind time and reach standard atmospheric pressure.Quick open/close door, inflate or the operating process such as vacuumizing all only needs the times of tens seconds just to realize train and platform rapid abutting joint, personnel can go up Train quickly.

28. the positioning track of magnetic suspension train is used as using the rail for taking turns rail railway, by suspension railway and driving track according to more reasonably arrangement, existing wheel track rail system can all be remained, the change rail system of magnetic-levitation can be used as by the use of existing wheel track turnout, make the construction cost of magnetic-levitation lower, and it is completely compatible with existing wheel rail railway.

29. spatial transition 23 is also connected by communicating pipe and valve with vacuum chamber.The volume of vacuum chamber is far longer than spatial transition 23, 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 1-lOPa or so, after spatial transition 23 and vacuum chamber, the rapid diffusion into vacuum chamber of gas in spatial transition 23, the pressure of spatial transition 23 is rapidly decreased to the 1/10 ~ 1/5 of normal atmosphere.Vacuum chamber can be multiple, sequentially open and vacuumize, vacuum can reach higher, and the pressure of spatial transition 23 can be reduced to the 1/100-1/1000 of normal atmosphere.
