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

[0004] In order to solve one of the above-mentioned technical defects, a transportation system is provided in an embodiment of the present application.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] Figure 2 A top view of the transportation system provided in the embodiment of the present application Figure 1 , Figure 3 A top view of the transportation system provided in the embodiment of the present application Figure 2 .like Figure 2 and Figure 3 As shown, the transportation system provided by this embodiment includes: a transportation pipeline 2, a track 3, a platform 4, a section closed door 5 and a ventilation shaft 6.

[0037] 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.

[0038] 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 includes a platform boarding and alighting area 41 and a platform track area 42, and both ends of the platform track area 42 are connected to the transport pipeline 2 respectively. The track 3 is arranged in the transport pipeline 2 and the platform track area 42.

[0039] Figure 4 for Figure 2 AA section view. Figure 4As shown, the track 3 is arranged in the transport pipeline 2. One track 3 may be arranged in the transport pipeline 2, or two or more tracks 3 may 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 vehicles on the two tracks 3 travel in opposite directions. The above-mentioned track 3 may be a track for an ordinary train, or may 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 driving speed and reducing noise.

[0040] 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.

[0041] Figure 5 for Figure 2 BB section view. Figure 5 As shown, a station 4 is provided at the end or middle portion 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.

[0042] The platform 4 is arranged on the side of the transport pipeline 2. When one track is arranged in the transport pipeline 2, the platform 4 can be arranged on one side of the transport pipeline 2; when two tracks are arranged in the transport pipeline 2, the platform 4 can be arranged on both sides of the transport pipeline 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 arranged on both sides of the transport pipeline 2. The vacuum degree in the platform 4 is the standard atmospheric pressure, that is, the platform 4 is in a normal pressure environment. The station can be an above-ground station or an underground station, and the platform 4 is located underground.

[0043] Two interval sealed doors 5 are used, which are respectively arranged at the two ends of the platform track area 42, and can be specifically arranged at the intersection of the platform track area 42 and the transportation pipeline 2. When the interval sealed door 5 is closed, the platform track area 42 and the transportation pipeline 2 are separated, which is equivalent to separating the normal pressure environment in the platform track area 42 from the low vacuum environment in the transportation pipeline 2.

[0044] When the maglev vehicle 7 is traveling in the transportation space, the interval sealed doors 5 on both sides of the platform are closed to ensure that the vacuum degree in the transportation space is maintained at the first preset value. When the maglev vehicle 7 is about to enter the station, the adjacent interval sealed door 5 is opened, and after the maglev vehicle 7 enters the station entry space, the interval sealed door 5 is closed. Since the vacuum degree in the carriage, the station entry space and the platform of the maglev vehicle is standard atmospheric pressure, a normal pressure environment is provided. When the door is opened, passengers can directly enter and exit the carriage. When the vehicle leaves the station, the interval sealed door on the other side of the platform is opened, allowing the vehicle to enter the next section of the transportation space and travel in a low vacuum environment; after the vehicle passes through the interval sealed door, the interval sealed door is closed. The vacuum degree in the transportation space will be lost during the opening process of the interval sealed door, which can be adjusted by a vacuum pump.

[0045] There are multiple air shafts 6, which are arranged at intervals along the extension direction of the transport pipeline 2, and the air shafts 6 are arranged on the side of the transport pipeline 2. An air shaft partition door 61 is arranged 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, which is equivalent to separating the normal pressure environment in the air shaft 6 from the low vacuum environment in the transport pipeline 2. When the air shaft partition door 61 is opened, the air shaft 6 is connected to the transport pipeline 2. During the operation of the vehicle, the air shaft partition door 61 is closed to ensure that the vacuum degree in the transport pipeline 2 meets the vehicle operation requirements.

[0046] When a vehicle breaks down or has a fire or other accident, if the vehicle has sufficient power to enter platform 4, passengers can get on and off platform 4 normally to evacuate; if the vehicle does not have sufficient power to enter platform 4, it can stop at the nearest air shaft 6, open the air shaft partition door 61, and supply air to the transport pipeline 2 through the air shaft 6 to form a normal pressure environment in the transport pipeline 2, and passengers can get off and evacuate from the air shaft 6.

[0047] The technical solution provided in this embodiment adopts a closed transport pipeline with a vacuum degree less than the standard atmospheric pressure and a platform with a vacuum degree of the standard atmospheric pressure, wherein the platform includes a platform boarding and alighting area and a platform track area, wherein both ends of the platform track area are respectively connected to the transport pipeline, and the tracks are laid in the transport pipeline and the platform track area; interval closed doors are respectively arranged at both ends of the platform track area, and when the interval closed doors are closed, the platform track area with a vacuum degree of the standard atmospheric pressure and the transport pipeline with a vacuum degree of the first preset value are separated; a plurality of air shafts are arranged at intervals along the extension direction of the transport pipeline, and the air shafts are arranged toward the ends of the transport pipeline. There is an air shaft partition door for separating the air shaft from the transport pipeline. The vehicle is subject to less air resistance when traveling in the transport space, which is beneficial to increase the driving speed, reduce driving noise and reduce energy consumption; when the vehicle is about to enter the station, the adjacent section closed door is opened, and the section closed door is closed after the rear of the vehicle passes, and passengers get on and off normally through the station entrance space; an air shaft partition door is provided at the end of the air shaft facing the transport pipeline, and the air shaft partition door is closed during the operation of the vehicle to ensure that the vacuum degree in the transport pipeline is a first preset value; when the vehicle breaks down or has an accident such as a fire, passengers can escape from the platform or air shaft.

[0048] When two stations on the line are close to each other, only the interval sealed doors 5 can be set on both sides of the station platform. When emergency escape is needed, the vehicle can enter the station and stop, close the interval sealed doors 5 on both sides, and then open the car door to allow passengers to escape; or the vehicle can stop next to a certain air shaft 6, close the interval sealed doors between the two stations, open the air shaft partition door 61 to supply air into the transport pipeline 2, restore the transport pipeline 2 to the standard atmospheric pressure, and then open the car door to allow passengers to escape from the air shaft 6.

[0049] When two stations on the line are far apart, multiple interval sealed doors 5 can be set between the two stations. Specifically, multiple interval sealed doors 5 are set at intervals in the transport pipeline 2. During normal vehicle driving, each interval sealed door 5 is in an open state. The air shaft 6 is set between two adjacent interval sealed doors 5, such as Figure 2As shown, when the vehicle is underpowered, it stops at the nearest air shaft 6, closes the interval sealed doors 5 on both sides of the air shaft 6, opens the air shaft partition door 61, and supplies air to the pipe space between two adjacent interval sealed doors 5 through the fan in the air shaft 6, which is connected with the air shaft 6 to form a normal pressure environment, which serves as an escape route for passengers to get off the vehicle and escape from the air shaft 6. When a fire occurs in the transport pipeline 2, the negative pressure formed between the transport pipeline 2 and the air shaft 6 is used to quickly convert the low vacuum environment between the two interval sealed doors 5 into a normal pressure environment, and passengers can evacuate to the ground through the air shaft 6. In the above scheme, the distance between the two interval sealed doors on both sides of the air shaft is much smaller than the distance between the two stations. Therefore, when emergency escape is required, air is supplied to the transport pipeline between the two interval sealed doors on both sides of the air shaft to make it a normal pressure environment, thereby reducing the loss of vacuum in the transport pipeline, so that it is not necessary to replenish more vacuum before resuming driving, thereby reducing energy consumption.

[0050] 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 through a pipeline to extract the air in the transport pipeline so that the vacuum degree in the transport pipeline 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.

[0051] 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.

[0052] In the above solution, the wind shaft 6 is fixedly installed with a wind shaft partition door 61. When the wind shaft partition door 61 and the interval sealing door 5 are closed, a low vacuum environment is formed in the transport pipeline 2. Figure 2 As shown, when the maglev vehicle 7 enters the platform space to stop, the sealed doors 5 on both sides of the section near the station are closed, the sealed doors 5 of the other sections in the transport pipe 2 are in an open state, and the air shaft partition door 61 is in a closed state. Passengers go from the normal pressure environment inside the maglev vehicle 7 to the normal pressure environment inside the station, and go to the underground station hall level through the stairs to exit the station or transfer. After the passengers get on and off the vehicle, the door is closed and the vehicle leaves the platform 4.

[0053] The control system is connected to each compartment sealed door 5 and the air shaft partition door 61. The control system calculates the opening and closing time of the compartment sealed door 5 according to the vehicle speed. When the vehicle enters the station entrance space, the air resistance of the normal pressure environment combined with the vehicle braking force causes the vehicle to slow down and enter the station. The control system is also used to control the action of the vacuum pump in the air shaft 6 to adjust the vacuum degree in the transport pipeline 2 to meet the requirements.

[0054] 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. There are multiple smoke sensors, which are respectively arranged in the station entry space and the transportation space, and send the detection signal 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.

[0055] 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.

[0056] 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.

[0057] On the basis of the above technical solution, this embodiment provides a specific implementation method of the interval sealed door 5: Figure 6 for Figure 2 Middle CC section view, Figure 7 This is a schematic diagram of the structure of a closed door in a transportation system provided in an embodiment of the present application. Figure 8 for Figure 7 A magnified view of area D in the middle. Fig. 9 for Figure 7 A magnified top view of region E in the middle.

[0058] like Figures 6 to 9As shown, the interval sealed door includes: a door drive device 51, a door transmission device 52 and a sealed door body 53. The door drive device 51 drives the sealed door body 53 to open through the door transmission device 52, specifically drives the sealed door body 53 to move upward to the top of the transport pipeline; the door drive device drives the sealed door body 53 to close through the door transmission device 52, specifically drives the sealed door body 53 to move downward to close the transport pipeline 2.

[0059] Figure 6 The shaded part in the figure is the interval sealed door 5. In a specific implementation method, a rectangular frame civil structure 8 is constructed by open excavation at the location where the interval partition door is to be set, and the opening of the civil structure 8 is connected to the transport pipelines 2 at both ends. The interval sealed door 5 is set at the opening of the civil structure 8, and is folded upward and stored at the top of the opening when opened, and unfolded downward to close the opening when closed, thereby separating the station normal pressure area and the transport pipeline as a low vacuum pipeline area, or dividing the transport pipeline into multiple areas.

[0060] The closed door body 53 can be made of high-quality steel, high-strength alloy steel, polymer material, or carbon nanomaterial.

[0061] The door driving device can be a driving motor, a cylinder or a hydraulic cylinder, and the door transmission device 52 can be a gear transmission, a sprocket transmission or other mechanisms.

[0062] The bottom of the closed door body 53 is provided with a notch 531 for avoiding the track 3. When the closed door body 53 moves downward to abut against the track surface and seal, the track 3 is located in the notch 531.

[0063] A closed door frame 55 is arranged in the transport pipe 2, and the closed door frame 55 is arranged on the periphery of the closed door body 53. A slot for accommodating the closed door body 53 is arranged in the closed door frame 55, and the closed door body 53 can slide vertically in the slot.

[0064] An elastic sealing ring 532 is provided at the end of the sealed door body 53 for sealing the gap between the track, the concrete structure beside the track and the secondary sealed door.

[0065] Furthermore, the interval sealed door 5 further includes: a secondary sealed door 54, which is arranged on both sides of the notch 531. The secondary sealed door 54 can move toward the notch 531 to the gap between the sealed track 3 and the sealed door body 53.

[0066] The secondary sealed door 54 specifically includes: a secondary sealed door driving device, a secondary sealed door frame and a secondary sealed door body. The secondary sealed door driving device is used to drive the secondary sealed door body to slide in the horizontal direction. The secondary sealed door frame is provided with a sealed card slot, the bottom end of the secondary sealed door body is slidably arranged in the closed card slot through a pulley, and an elastic sealing ring is arranged on the periphery of the secondary sealed door body.

[0067] Furthermore, a vacuum detection device 56 is disposed at the interval sealed door 53 to detect whether there is a gas leakage between the interval sealed door 53 and the transport pipeline 2 .

[0068] During the closing process of the interval sealed door 5, the sealed door body 53 is first driven downward to seal with the track and the concrete structure beside the track, and then the secondary sealed door 5 is driven to move horizontally toward the track to seal. The vacuum detection device 56 detects whether there is gas leakage at the interval sealed door 5 and the secondary sealed door 54. If there is leakage, the vacuum detection device 56 transmits a wireless signal to the door driving device 51, so that it drives the sealed door body 53 to continue to move downward and apply a tightening force until there is no more gas leakage.

[0069] Fig.10 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.10 As shown, based on 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.

[0070] 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 163 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.

[0071] 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 9 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 9. A specific method: in two adjacent air shafts 6, the fan 65 in one air shaft 6 supplies air to the cable channel 9, and the fan 65 in the other air shaft 6 exhausts air from the cable channel 9 to the outside, so that the air forms an orderly flow in the cable channel 9, ensuring the normal air environment when personnel enter and exit the cable channel 9 for maintenance. When a fire occurs in the transport pipeline 2, the interval airtight doors 5 at both ends of the air shaft 6 are closed, the air shaft partition door 61 is opened, and the fan 65 is started to supply air to the transport pipeline 2, and passengers can enter the air shaft against the direction of smoke flow to evacuate.

[0072] In order to improve the utilization efficiency of the track 3, the track 3 may further include a switch structure.

[0073] like Figure 4 and Figure 5 As shown, an equipment cable channel 9 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.
