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

[0007] A plurality of air shafts are arranged at intervals along the extension direction of the transport pipeline;

[0008] One end of the telescopic enclosed passage is butted against a side of the platform partition door facing the platform track area, and the other end can be extended toward the platform track area to butt against the outer periphery of a vehicle door.

[0027] 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.

[0028] 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.

[0029] Figure 1 This 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.

[0030] Figure 2 A top view of a transportation system provided in an embodiment of the present application, Figure 3 for Figure 2 Cross-sectional view of area A in the middle, Figure 4 for Figure 2 Cross-sectional view of area B. Figure 2As 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.

[0031] 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.

[0032] 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 value of 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. The platform 4 is provided with a platform partition door 41, which is used to separate the platform into a platform boarding and alighting area 42 with a vacuum degree of standard atmospheric pressure and a platform track area 43 with a vacuum degree of the first preset value. Both ends of the platform track area 43 are connected to the transport pipeline 2 respectively.

[0033] like Figure 3 As shown, 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 two-way operation mode or a multi-line two-way 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 for 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 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.

[0034] The maglev vehicle 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, and Chinese high temperature superconducting. The blocking ratio between the maglev vehicle and the transport pipeline 2 is 0.1 to 0.3, and can be specifically 0.1, 0.15, 0.2, 0.25, and 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.

[0035] like Figure 4 As shown, a station 4 is provided at the end or middle portion of the track 3. Figure 1In 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Figure 5 for Figure 4 Enlarged view of the middle C area. The telescopic enclosed 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 enclosed passage 5 is butted against the platform partition door 41. The telescopic enclosed passage 5 is a telescopic structure. When no vehicle enters the station, the telescopic enclosed passage 5 is folded and retracted to the position of the platform partition door 41. After the vehicle enters the station, the telescopic enclosed 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 5 After the telescopic sealed passage 5 is sealed and connected to the outer periphery of the vehicle door, when the platform partition door 41 and the vehicle door are opened, the telescopic sealed passage 5 connects the interior of the vehicle compartment with the passenger boarding and alighting area 42 of the platform 4, providing a normal pressure environment with a vacuum degree of standard atmospheric pressure for passengers to board and alight.

[0040] 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.

[0041] The working process of the above transportation system is:

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The technical solution provided in this embodiment adopts a transport pipeline, a track, a platform, an air shaft and a telescopic closed passage; 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 standard atmospheric pressure and a platform track area with a vacuum degree of a 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 a first preset value, which is less than the standard atmospheric pressure; the track is arranged in the transport pipeline and the platform track area; a plurality of air shafts are arranged at intervals along the extension direction of the transport pipeline; one end of the telescopic closed passage is connected to the side of the platform partition door facing the platform track area, and the other end can be extended to the platform track area to connect with the outer periphery of the vehicle door; the vehicle is subject to less air resistance when traveling in the transport space, which is conducive to increasing the driving speed, reducing driving noise and reducing energy consumption; when the vehicle enters the station, the telescopic closed passage is extended to connect with the door, and the door and the platform partition door are opened, and the telescopic closed passage provides a normal pressure environment with the carriage and the platform, and passengers get on and off the vehicle through the telescopic closed passage to ensure passenger safety.

[0046] Furthermore, an air shaft partition door 61 is provided at the end of the air shaft 6 facing the transport pipeline 2. When the air shaft partition door 61 is closed, the air shaft 6 is separated from the transport pipeline 2, so that the air shaft 6 is kept at a standard atmospheric pressure, and the vacuum degree in the transport pipeline 2 is kept at a first preset value. When the air shaft partition door 61 is opened, the air shaft 6 is connected to the transport pipeline 2. During normal operation of the vehicle, the air shaft partition door 61 is closed.

[0047] Figure 6 for Figure 2 Cross-sectional view of region D in the figure. Figure 6 As shown, on the basis of the above technical solution, a telescopic closed passage 5 is also provided at the location of the air shaft 6. Specifically, one end of the telescopic closed passage 5 is butted against the side of the air shaft partition door 61 facing the transport pipe 2, and the other end can be stretched to be sealed against the outer periphery of the vehicle door (stretching direction is as shown in FIG. Figure 6When the air shaft partition door 61 is opened, the telescopic closed passage 5 is connected to the inner space of the air shaft.

[0048] When a vehicle breaks down or has a fire or other accidents, 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, it stops at the nearest air shaft 6, the telescopic closed passage 5 at the air shaft 6 is extended to seal with the vehicle door, the vehicle door and the air shaft partition door 61 are opened, and the passengers can escape from the air shaft 6.

[0049] 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.

[0050] 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.

[0051] 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 or the air shaft partition door, 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.

[0052] 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.

[0053] In addition, 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.

[0054] The platform partition door 41, air shaft partition door 61 and telescopic drive device 51 are all connected to a control system, which controls the operation of each component so that the vacuum degree in the transport pipeline 2 meets the requirements and enables vehicles to enter and exit the station smoothly.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Figure 7This 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. Figure 7 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.

[0060] 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.

[0061] 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 .

[0062] Figure 6 It is shown that a fan 65 is arranged in the air shaft 6. The air shaft 65 is connected to the cable channel 8 through a 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. 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 fan 65 in the other air shaft 6 exhausts air from the cable channel 8 to the outside, so that the air forms an orderly flow in the cable channel 8 and the air shaft 6, ensuring the normal air environment when personnel enter and exit the cable channel 8 for maintenance and the normal air environment when personnel in the air shaft 6 are rescued and evacuated.

[0063] In order to improve the utilization efficiency of the track 3, the track 3 may further include a switch structure.

[0064] like Figure 3 and Figure 4 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.
