Description

Technical Field

[0001] The present application relates to transportation technology, and in particular to a transportation system. Background Art

[0002] At present, the main modes of transportation include water transportation, road transportation, rail transportation (including urban subways), and air transportation. Water transportation appeared the earliest. Before air transportation, humans mainly relied on water transportation to cross the ocean, but its speed was low. The advantages of road transportation are flexibility, convenience, and door-to-door, but its disadvantages are relative disorder and relative unreliability of human operation, which lead to more traffic accidents, and currently there is serious traffic congestion and high consumption of oil resources. Railway transportation is a land transportation method suitable for long-distance and large-scale passenger and freight transportation. Its influence ranks first among all industries in the national economy. However, when the speed of wheel-rail high-speed rail is greater than 400km / h, the train traction drive power is mainly used to overcome aerodynamic resistance, energy consumption increases rapidly, economy is poor, noise and vibration are high, and high-speed rail stations need to be located at a certain distance from the main urban area and need to be connected by other modes of transportation. Air transportation, as a highly flexible mode of transportation, has advantages in crossing obstacles such as oceans and mountains. Its disadvantages are high fuel consumption and great influence from weather. The airport is far away from the urban area, and other modes of transportation are needed to connect to the urban area, which requires multiple transfers and the total time is still relatively long.

[0003] Therefore, there is an urgent need for a new type of fast, low-energy transportation system to shorten the time of long-distance transportation and facilitate the travel and transfer of people in the city center where passenger flow is concentrated. Summary of the invention

[0030] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0031] This embodiment provides a transportation system with the characteristics of high speed, low energy consumption, little impact by external climate, and low noise and vibration.

[0032] Figure 1This is a schematic diagram of the structure of the transportation system connecting two cities provided in the embodiment of the present application. Figure 1 As shown, the transportation system 11 is connected between the first city road network 12 and the second city road network 13. Passengers can directly transfer to the rail transit in the urban area after exiting the transportation system 11. In busy areas such as urban areas, the transportation system 11 can be set in an underground tunnel to facilitate docking and transfer with the underground rail transit of each city road network. It is not only convenient for urban residents to take and transfer, but also can reduce the problems of land acquisition and demolition caused by ground construction, occupation of urban road space and impact on urban landscape. The part between the two cities can be set on the ground or on an elevated bridge.

[0033] Figure 2 A top view of the transportation system provided in the embodiment of the present application. Figure 2 As shown, the transportation system provided by this embodiment includes: a transportation pipeline 2, a track 3, a platform 4, a telescopic closed passage 5 and a ventilation shaft 6.

[0034] The transport pipeline 2 can be constructed by shield tunneling with shield segments connected by sealing. The segments are prefabricated with high-performance concrete with good density. The segments are sealed and waterproofed with rubber gaskets, water-expanding rubber, cork pads and other materials. The segments can also be coated with waterproof and airtight paint. The open-cut method can also be used to cast steel bars as a whole into a rectangular frame structure. The mining method can also be used to construct the initial support and then cast the secondary lining. This embodiment takes the transport pipeline 2 built in the tunnel as an example to explain in detail the implementation method of the transportation system.

[0035] The transport pipeline 2 is a closed pipeline, and the vacuum degree inside it is a first preset value, which is less than the standard atmospheric pressure. When the first preset value is 0.01 standard atmospheric pressure to 0.5 standard atmospheric pressure, the transport pipeline 2 can be called a low vacuum pipeline.

[0036] Figure 3 for Figure 2 AA section view. Figure 2 and Figure 3 As shown, the platform 4 is provided with a platform partition door 41 for separating the platform into a platform boarding and disembarking area 42 with a vacuum degree of standard atmospheric pressure and a platform track area 43 with a vacuum degree of a first preset value, and both ends of the platform track area 43 are respectively connected to the transport pipeline 2.

[0037] The track 3 is arranged in the transport pipeline 2 and the platform track area 43, and is used to guide the travel of the vehicle. One track 3 can be arranged in the transport pipeline 2, or two or more tracks 3 can be arranged to realize a double-line bidirectional operation mode or a multi-line bidirectional operation mode. In the implementation mode provided in this embodiment, two parallel tracks 3 are arranged in the transport pipeline 2, and the vehicles on the two tracks 3 travel in opposite directions. The above-mentioned track 3 can be a track of an ordinary train, or it can be a magnetic levitation track. In the implementation mode provided in this embodiment, the track 3 is a magnetic levitation track. The magnetic levitation vehicle 7 travels in a low vacuum environment in a low vacuum pipeline, and the air resistance is small, which is conducive to increasing the travel speed and reducing noise.

[0038] A horizontal track plate is arranged in the transport pipeline 2, and the track is laid on the track plate.

[0039] The maglev vehicle 7 can be a conventional maglev vehicle, a high temperature superconducting maglev vehicle or a low temperature superconducting maglev vehicle, such as an ultra-high speed maglev vehicle 7 of the German TR (Transrapid) series, Japanese low temperature superconducting, Chinese high temperature superconducting, etc. The blocking ratio between the maglev vehicle 7 and the transport pipeline 2 is 0.1 to 0.3, specifically 0.1, 0.15, 0.2, 0.25, 0.3. The blocking ratio is the ratio of the cross-sectional area of ​​the vehicle to the clearance area above the rail surface in the transport pipeline 2.

[0040] Stations 4 are provided at the ends or in the middle of the track 3. Figure 1 In the scheme shown, stations can be set up only in the first city and the second city respectively; when the first city and the second city are far apart and there is a third city between them, a station can also be set up in the third city.

[0041] When one track is provided in the transport pipe 2, the platform 4 can be provided on one side of the transport pipe 2; when two tracks are provided in the transport pipe 2, the platform 4 can be provided on both sides of the transport pipe 2, so that passengers can get on and off the platform on both sides. In the implementation provided in this embodiment, the platform 4 is provided on both sides of the transport pipe 2.

[0042] When the vehicle enters the platform track area 43 and stops at the station, the vacuum degree outside the vehicle is still the first preset value. The other side of the platform partition door 41 is at standard atmospheric pressure, that is, a normal pressure environment. The station can be an above-ground station or an underground station, and the platform 4 is located underground.

[0043] For example: the station includes the first underground floor and the second underground floor, and the platform partition door 41 is set on the second underground floor, dividing the second underground floor into a normal pressure environment area (i.e., the platform boarding and disembarking area) and a low vacuum environment area (platform track area), and the low vacuum environment area is connected to the transportation pipeline 2.

[0044] Figure 4 for Figure 3 A magnified view of area B. Figure 4 As shown, the telescopic closed passage 5 is arranged on the side of the platform partition door 41 facing the platform track area 43. Specifically, one end of the telescopic closed passage 5 is butted against the platform partition door 41. The telescopic closed passage 5 is a telescopic structure. When no vehicle enters the station, the telescopic closed passage 5 is folded and retracted to the position of the platform partition door 41. After the vehicle enters the station, the telescopic closed passage 5 extends toward the platform track area 43, and the other end thereof is butted against the outer periphery of the door of the maglev vehicle 7, and is tightly sealed against the outer surface of the maglev vehicle 7, as shown in FIG. Figure 4 After the telescopic sealed passage 5 is sealed and connected to the outer periphery of the door, when the platform partition door 41 and the door are opened, the telescopic sealed passage 5 connects the interior of the carriage with the platform boarding and alighting area 42, providing a normal pressure environment with a vacuum degree of standard atmospheric pressure for passengers to board and alight.

[0045] There are multiple air shafts 6, which are arranged at intervals along the extension direction of the transport pipeline 2. The air shafts 6 are arranged on the side of the transport pipeline 2. The air shafts 6 are separated from the transport pipeline 2, and the vacuum degree in the air shafts 6 is the standard atmospheric pressure.

[0046] The working process of the above transportation system is:

[0047] Before the vehicle enters the station, the platform partition door 41 is closed, and the telescopic closed passage 5 is in a folded state and retracted to the position of the platform partition door 41. The inside of the transport pipe 2 is a closed low vacuum environment, and the vehicle has less air resistance and noise when traveling in the transport pipe 2, and can reach a higher driving speed.

[0048] After the vehicle enters the station and stops at the platform, the telescopic enclosed passage 5 is extended to seal against the outer periphery of the door. After the seal is good, the door and platform partition door 41 are opened, and the passengers in the car enter the platform through the telescopic enclosed passage 5, and the passengers in the platform enter the car through the telescopic enclosed passage 5.

[0049] Before the vehicle leaves the station, the vehicle door and the platform partition door 41 are closed, and then the telescopic closed passage 5 is folded. The vehicle starts to leave the platform.

[0050] When a vehicle breaks down or has a fire or other accident, if the vehicle has enough power to drive into the platform 4, the telescopic closed passage 5 is extended to seal with the vehicle door, the vehicle door and the platform partition door 41 are opened, and the passengers can escape from the platform 4. If the vehicle does not have enough power to drive into the platform 4, this embodiment provides a method for realizing escape and evacuation:

[0051] Figure 5 for Figure 2 CC section view. Figure 2 and Figure 5As shown, a sub-track channel 32 is provided below the track plate 31. The vacuum degree in the sub-track channel 32 is standard atmospheric pressure and can be connected to the ground. A horizontal sliding sealed door 9 is provided at the joint between the sub-track channel 32 and the track plate 31. The horizontal sliding sealed door 9 can be slid open or closed in the horizontal direction. When the horizontal sliding sealed door 9 is closed, the low vacuum environment in the transport pipeline 2 and the normal pressure environment in the sub-track channel 32 are isolated. When a vehicle breaks down or a fire occurs, if the vehicle does not have enough power to drive into the platform 4 or the air shaft 6, it can be parked nearby in the transport pipeline 2. Passengers wear oxygen masks and oxygen cylinders, get off the vehicle and enter the transport pipeline 2, and then open the horizontal sliding sealed door 9 to evacuate and escape from the track channel 32 to the platform 4 or the air shaft 6.

[0052] The technical solution provided in this embodiment adopts a transport pipeline, a track, a platform, an air shaft and a telescopic closed passage, wherein the platform is provided with a platform partition door for dividing the platform into a platform boarding and disembarking area with a vacuum degree of the standard atmospheric pressure and a platform track area with a vacuum degree of the first preset value; both ends of the platform track area are respectively connected to the transport pipeline, and the vacuum degree in the transport pipeline is the first preset value, which is less than the standard atmospheric pressure; the track is arranged in the transport pipeline and the platform track area, and the vehicle is subject to less air resistance when traveling in the transport space, which is conducive to increasing the driving speed, reducing the driving noise and reducing the energy consumption; a plurality of air shafts are arranged along the transport pipeline. The telescopic enclosed passage is arranged at intervals in the extension direction of the track; one end of the telescopic enclosed passage is butted against the side of the platform partition door facing the platform track area, and the other end can be extended toward the platform track area to be butted against the outer periphery of the vehicle door. After the telescopic enclosed passage is sealed and butted against the vehicle door, the vehicle door and the platform partition door are opened, and passengers can get on and off the vehicle through the telescopic enclosed passage; a horizontal track plate is arranged in the transport pipeline, and an under-track channel is arranged under the track plate, and a horizontal sliding enclosed door is arranged at the junction of the under-track channel and the track plate; the vacuum degree in the under-track channel is standard atmospheric pressure, so that passengers can enter the under-track channel from the horizontal sliding enclosed door for evacuation to ensure personnel safety.

[0053] The vacuum degree in the above-mentioned transport pipeline 2 is 0.01 standard atmosphere to 0.5 standard atmosphere, specifically 0.01 standard atmosphere, 0.05 standard atmosphere, 0.1 standard atmosphere, 0.15 standard atmosphere, 0.2 standard atmosphere, 0.25 standard atmosphere, 0.3 standard atmosphere, 0.35 standard atmosphere, 0.4 standard atmosphere, 0.45 standard atmosphere, and 0.5 standard atmosphere.

[0054] The telescopic closed channel 5 includes: a telescopic channel body and a suction sealing device. The telescopic channel body is a cylindrical structure, for example, a structure of an inner frame and an outer skin can be adopted, and the inner frame can be a structure hinged by multiple connecting rods. One end of the telescopic channel body is connected to the platform partition door 41, and the other end is provided with a suction sealing device, which is used to tightly suck the outer surface of the vehicle. The suction sealing device can specifically be an electromagnet, and a suction mechanism is also provided on the outer surface of the vehicle. The suction mechanism and the electromagnet are energized and sucked together to achieve the end of the telescopic channel body being tightly abutted against the outer surface of the vehicle.

[0055] A method for realizing a suction sealing device: the suction sealing device is an elastic sealing ring with an electromagnet embedded inside, and the elastic sealing ring can seal the gap between the telescopic closed channel and the outer surface of the vehicle.

[0056] In addition, if Figure 4 As shown, the telescopic closed passage also includes: a telescopic drive device 51, which is used to drive the telescopic passage body to extend or contract in the horizontal direction. The telescopic drive device 51 can be implemented by the principles of motor drive, hydraulic drive or pneumatic drive.

[0057] The platform partition door 41 and the telescopic driving device 51 are both connected to a control system, which controls the actions of the components so that the vacuum degree in the transport pipeline 2 meets the requirements and enables vehicles to enter and exit the station smoothly.

[0058] In addition, a vacuum detection device can also be used, which is arranged at the end of the telescopic channel body 5 to detect the vacuum degree in the telescopic channel body 5. The vacuum detection device is connected to the control system and is used to send detection data to the control system. When the telescopic channel body 5 is extended to abut against the outer surface of the vehicle and the platform partition door 41 is opened, the vacuum degree in the telescopic channel body 5 is detected by the vacuum detection device. If it is the standard atmospheric pressure, the door can be opened; if it is lower than the standard atmospheric pressure, the control system controls the telescopic channel body 5 to continue to move toward the vehicle according to the detection data of the vacuum detection device, and applies a tightening force to press the vehicle until the vacuum degree in the telescopic channel body 5 reaches the standard atmospheric pressure.

[0059] Furthermore, the transportation system also includes a disaster prevention alarm device connected to the control system signal, including a smoke sensor, an alarm and a fire extinguishing device installed in the transportation pipeline 2. The number of smoke sensors is multiple, and they are arranged at intervals in the transportation pipeline 2. The detection signal is sent to the control system. The control system controls the fire extinguishing device at the corresponding position to extinguish the fire according to the detection result, and controls the alarm to sound an alarm. The fire can be detected in the first time through the disaster prevention alarm device, which is convenient for timely alarming so that passengers can escape.

[0060] In order to further meet the passengers' riding comfort and safety, the above-mentioned magnetic levitation vehicle 7 can also be equipped with a life support system, a lighting system, a communication system and a security system, such as: providing the atmospheric pressure required for normal survival of life, closed doors on the vehicle body, special clothing that can adapt to low vacuum environment for a short time in the event of accidents and fires, portable oxygen breathing bottles, etc.

[0061] The maglev vehicle 7 runs in the transport pipeline 2 providing a low vacuum environment, and the travel speed can reach 600km / h to 1000km / h, which can eliminate most of the air resistance, reduce the running noise, and reduce the impact of external climate. In busy areas such as urban areas, the transport pipeline 2 can be conveniently connected and transferred with the rail transit network in the city, which is not only convenient for urban residents to ride and transfer, but also reduces the land acquisition and demolition caused by construction on the ground and the impact on the urban landscape.

[0062] This embodiment provides a specific implementation method of the track plate 31 and the under-track channel 32: Figure 5 As shown, two vertical track support bodies 33 are arranged below the track plate 31, and the track support bodies 33 extend in the same direction as the track 3, and a closed space relative to the transport pipe 2 is enclosed between the two track support bodies 33. The under-track channel 32 includes a vertical channel and a horizontal channel, wherein the vertical channel is arranged in the space between the two track support bodies 33 and docks with the horizontal sliding closed door 9, and the horizontal channel extends in the horizontal direction and communicates with the air shaft 6.

[0063] Figure 6 for Figure 2 DD section view. Figure 6 As shown, an air shaft partition door 61 is provided at the end of the air shaft 6 facing the transport pipeline 2 to maintain the air shaft 6 at standard atmospheric pressure. The height of the air shaft partition door 61 is lower than the track plate 31, and the under-track passage 32 is connected to the air shaft partition door 61, and passengers can escape and evacuate from the air shaft 6 through the under-track passage 32. During normal operation of the vehicle, the air shaft partition door 61 is closed.

[0064] Furthermore, an evacuation staircase 34 is provided in the vertical passage, and the top end of the evacuation staircase 34 extends to the horizontal sliding airtight door 9, and the bottom end extends to the bottom surface of the vertical passage.

[0065] At the left and right centerline positions of the transport pipeline 2, along the extension direction of the transport pipeline 2, a horizontal sliding sealed door 9 is provided at intervals of 300m-800m, which is used to isolate the low vacuum environment of the transport pipeline 2 and the normal pressure environment of the under-rail channel 32 during operation. The distance between the horizontal sliding sealed doors 9 can be specifically 300m, 400m, 500m, 600m, 700m, and 800m.

[0066] For the horizontal sliding sealed door 9, this embodiment provides a specific implementation method:

[0067] Figure 7 A top view of the horizontal sliding airtight door provided in this embodiment, Figure 8 The side view of the horizontal sliding airtight door provided in this embodiment. Figure 7 and Figure 8 As shown, the horizontal sliding closed door 9 comprises: a sliding door body 91, a door body driving device and a door body guiding device. The door body driving device and the door body guiding device are arranged on the track plate 31, and the door body driving device is used to drive the sliding door body 91 to slide horizontally along the door body guiding device.

[0068] One implementation method: The door body driving device includes: a door signal control mechanism 92, a drive motor 93, a transmission mechanism and a door connecting member 95. The transmission mechanism can be a gear transmission, a chain transmission, a belt transmission, etc. In this embodiment, the gear transmission is taken as an example, and the transmission mechanism includes: a driving gear 941, a driven gear 942 and a transmission chain 943.

[0069] The door signal control mechanism 92 is connected to the controller in the transportation system for receiving the control signal sent by the controller. The door signal control mechanism 92 is also electrically connected to the drive motor 93. When the door signal control mechanism 92 receives the door opening command sent by the controller, it controls the drive motor 93 to start.

[0070] The driving gear 941 is connected to the output end of the driving motor 93, and the transmission chain 943 is sleeved on the driving gear 941 and the driven gear 942. One end of the door connecting member 95 is fixed on the transmission chain 943, and the other end is connected to the sliding door body 91. After the driving motor 93 starts to rotate in the forward direction, it drives the driving gear 941 to rotate, and then drives the driven gear 942 to rotate through the transmission chain 943, and drives the door connecting member 95 to move horizontally, so that the sliding door body 91 moves horizontally to open. When the driving motor 93 starts to rotate in the reverse direction, it drives the sliding door body 91 to close.

[0071] One implementation method: the door body guide device includes: guide rails 96 respectively arranged on both sides of the sliding door body 91, and the guide rails 96 are provided with guide grooves facing the inner side of the sliding door body 91. The opposite sides of the sliding door body 91 are slidably arranged in the guide grooves of the guide rails 96 on both sides.

[0072] Ball bearings and lubricants may be provided between the sliding door body 91 and the guide groove, so that rolling friction occurs between the sliding door body 91 and the guide groove, thereby improving the smoothness of the opening and closing of the sliding door body 91. When the sliding door body 91 is closed, the guide rail 96, lubricant and ball bearings can also play a role in isolating air, ensuring that the vacuum degree in the transport pipeline 2 meets the requirements, and also ensuring that the vacuum degree of the channel 32 under the rail is maintained at the standard atmospheric pressure.

[0073] Furthermore, electromagnets with elastic sealing rings are installed at the bottom of both ends of the sliding door body 91 along the moving direction, which can absorb and fix the sliding door body 91 to keep it in a closed state or an open state.

[0074] In the event of a vehicle accident and complete loss of power, the vehicle stops in the transport pipe 2. The controller opens the horizontal sliding sealed door closest to the vehicle parking position, allowing passengers to enter the under-rail channel 32 for evacuation. In addition, the fan can be started to supply air to the under-rail channel 22 to maintain good ventilation, and external rescue personnel can also enter the transport pipe 2 from the air shaft 6 in the reverse direction for rescue.

[0075] Of course, there is another way: the under-track passage 32 can also be connected to the platform boarding and alighting area 42 of the station.

[0076] Along the extension direction of the transport pipeline 2, the intervals between the air shafts 6 are 2km to 4km, such as 2km, 3km, and 4km. The air shaft 6 can be built before the transport pipeline 2 is constructed. During the construction of the transport pipeline 2, the air shaft 6 can be a construction shaft excavated by the shield machine hoisting or mining method. A vacuum pump station is set in the air shaft 6, which is connected to the transport pipeline 2 through a pipeline to extract the air in the transport pipeline 2 so that the vacuum degree in the transport pipeline 2 reaches a low vacuum state of a first preset value. During the construction and operation of the transportation system, the air shaft 6 can also be used as an escape route to ensure the safety of personnel.

[0077] Fig. 9 This is a schematic diagram of the distribution of vacuum pumps on the transmission pipeline in the transportation system provided in the embodiment of the present application. Fig. 9 As shown, on the basis of the above technical solution, a vacuum pump 62, a control valve 63 and a pressure transmitter 64 are arranged in the air shaft 6, wherein the vacuum pump 62 is connected to the transport pipeline 2 through a gas pipeline, and is used to extract the air in the transport pipeline 2 so that the vacuum degree in the transport pipeline 2 reaches a first preset value. The control valve 63 is arranged on the gas pipeline, and is used to control the on and off of the gas pipeline. The pressure transmitter 64 is arranged on the transport pipeline 2, and is used to detect the air pressure signal in the transport pipeline 2, and then obtain the vacuum degree.

[0078] The vacuum pump 62 may be a water (liquid) ring vacuum pump and / or a screw vacuum pump. The control valve 63 may be a gate valve and / or a baffle valve. The pressure transmitter 64 is connected to the control system signal and sends the detected air pressure signal to the control system so that the control system controls the vacuum pump 62 and the control valve 63 to maintain the air pressure in the transport pipeline 2 stable.

[0079] During the opening and closing process of the telescopic closed passage 5 , the vacuum degree may be lost in the transport pipeline 2 , which can be adjusted and maintained by the vacuum pump 62 in the air shaft 6 .

[0080] Figure 6 It is shown that a fan 65 is arranged in the air shaft 6. The air shaft 65 is connected with the cable channel 8 and the channel under the track 32 through the ventilation duct pre-buried in the bottom plate of the air shaft. Under normal operation of the vehicle, the fan 65 can be started regularly to supply air to the cable channel 8 and the channel under the track 32. A specific method: in two adjacent air shafts 6, the fan 65 in one air shaft 6 supplies air to the cable channel 8 and the channel under the track 32, and the fan 65 in the other air shaft 6 exhausts air from the cable channel 8 and the channel under the track 32 to the outside, so that the air forms an orderly flow in the cable channel 8 and the channel under the track 32, providing a normal maintenance air environment in the cable channel 8 and a normal escape and rescue air environment in the channel under the track 32.

[0081] When a fire occurs in the transport duct 2, the fan 65 can be started to supply air to the under-track passage 32 to ensure that passengers can maintain normal breathing when entering the under-track passage 32. Further, when the horizontal sliding airtight door 9 is opened, the smoke in the transport duct 2 will enter the under-track passage 32. The fan 65 in one air shaft 6 is used to supply air to the under-track passage 32, and the fan 65 in the adjacent air shaft 6 exhausts air from the under-track passage 32 to the outside, and the smoke is discharged. Passengers can also enter the air shaft against the direction of the smoke flow to evacuate.

[0082] In order to improve the utilization efficiency of the track 3, the track 3 may further include a switch structure.

[0083] like Figure 3 and Figure 5 As shown, an equipment cable channel 8 is also provided in the transport pipeline 2 and the platform 4, in which various equipment and cables, such as electric wires, signal wires, etc., can be arranged.
