Examples:
referring to fig. 1 to fig. 4, the configuration of the transition section of the magnetic levitation pipeline in the preferred embodiment of the present invention is disposed on the magnetic levitation vacuum pipeline 3, which can be regarded as replacing a part of the pipeline on the pipeline magnetic levitation traffic line with the vacuum pipeline 3 in the preferred embodiment of the present invention, thereby completing the auxiliary interception braking of the magnetic levitation train 1 on the permanent magnetic track 2 and assisting the rescue and evacuation of the passengers on the magnetic levitation train 1 after the emergency braking.
Specifically, the transition section structure comprises a plurality of openable gates 4 which are arranged at intervals in the longitudinal direction of the vacuum pipeline 3, and pipeline units with two ends closed can be formed in the vacuum pipeline 3 by utilizing the simultaneous closing of the two gates 4 in the longitudinal direction, so that the maglev train 1 can complete emergency braking and emergency evacuation in the corresponding pipeline units.
In actual setting, the shutter 4 is disposed inside the vacuum pipe 3 and is provided with a shutter opening controller 5 corresponding thereto, and the shutter 4 can be controlled to be maintained in an open state or a closed state by control of the shutter opening controller 5.
In a specific embodiment, the gate 4 includes a plurality of gate units sequentially arranged side by side in the transverse direction of the pipeline, each gate unit extends vertically and can be lifted vertically respectively, and correspondingly, a containing bin capable of containing the gate units and driving the gate units to perform vertical lifting movement and a driving mechanism are arranged on the outer side of the top of the pipeline.
It will be appreciated that when the door unit is actually set, a through groove penetrating through the inside and outside needs to be formed in the top area of the pipeline, and at this time, the vacuum pipeline 3 in the through groove forming area needs to be subjected to connection and reinforcement treatment at both ends, and the opening area is sealed, so that the tightness of the pipeline when the gate 4 works and when the gate does not work is ensured. In actual arrangement, preferably, an elastic sealing element is arranged at the bottom of each door body unit, and can be abutted against a running platform or other in-pipe structures in the pipeline when the door body units work, so that the abutting part is sealed; accordingly, each resilient seal may seal the channel at the top of the duct when the door unit is retracted.
Of course, in addition to the above-described implementation, the installation form of the shutter 4 may be set to another form as required in the actual installation, for example, the shutter 4 of a spiral vane type may be opened or closed by synchronous spiral control of each vane unit installed in combination. It is however obvious that a housing compartment for housing the fan blade unit and a control mechanism for controlling the movement of the fan blade unit are provided outside the vacuum duct 3.
Further, on the vacuum pipe 3 between the two gates 4 spaced apart in the longitudinal direction, a breaking unit and an air pressure sensor 7 are correspondingly provided. The air breaking unit in the preferred embodiment is an air breaking valve 6 which is connected to the outer side of the vacuum pipeline 3 in a sealing way and is communicated with the internal environment of the pipeline, and is used for introducing pressure gas into the pipeline unit after the two gates 4 are closed respectively, increasing the air pressure in the pipeline unit, ensuring that the air pressure in the pipeline unit is consistent with the atmospheric pressure, enabling passengers on a vehicle to enter the vacuum pipeline 3 after emergency braking, and then completing emergency evacuation.
In actual setting, the emptying valve 6 is electrically connected with the gate 4 or the control system of the gate 4, and is used for starting working after the corresponding two gates 4 are closed (namely, after the pipeline units with two closed ends are formed). Accordingly, an air pressure sensor 7 is provided inside the vacuum duct 3, which is provided in a plurality of spaced apart relation between the two gates 4, for detecting the air pressure in each region of the duct unit. Meanwhile, the air pressure sensor 7 is in communication connection with the control system of the magnetic levitation train 1, and can feed back the detection result to the magnetic levitation train 1 with emergency braking in the pipeline unit in real time, so that the magnetic levitation train 1 can conveniently judge the air pressure condition outside the train in real time, and whether the vehicle door can be opened for emergency evacuation is determined.
Because the two gates 4 are correspondingly closed in the longitudinal direction, a pipeline unit with a certain length is formed in the vacuum pipeline 3, at the moment, an air bag with certain air pressure can be formed in the pipeline unit by ventilation in the pipeline unit, the air bag reacts on the maglev train 1, the running resistance of the maglev train 1 is increased, and assistance is provided for emergency braking of the maglev train 1. Meanwhile, in actual setting, the air ventilation is preferably started from one end deviating from the coming direction of the train, so that the air in the pipeline unit is diffused from one side deviating from the coming direction to one side of the coming direction, and the blocking effect on the outer side of the train is increased. Meanwhile, in the continuous running process of the train, the air volume in the pipeline unit is further compressed, the blocking of the maglev train 1 is gradually increased, and the braking interception of the maglev train 1 is further assisted.
Further, in the preferred embodiment, an interception net assembly is also arranged in the pipeline unit with two closed ends, and comprises an interception net 8 which is folded and packaged at the top end of the pipeline, winches 9 which are respectively arranged at two lateral sides of the pipeline, and brakes 10 which are mounted at two lateral sides of the pipeline. In a preferred embodiment, the two ends of the interception net 8 are respectively connected with two winches 9, so that after the interception net 8 falls from the top of the pipeline, the two winches 9 can tighten the two ends thereof respectively. Meanwhile, the brake 10 in the preferred embodiment is designed as a water turbine energy absorber, which includes a rotor enclosed in a sealed cavity and a brake band wound around the rotor at one end. The other end of the brake net belt is connected with the interception net 8 through a shearing separation pin, so that the brake net belt can not be carried out as long as the shearing separation pin is not broken; correspondingly, the rotor is a conical blade, and the sealing cavity is filled with anti-freezing and anti-corrosion brake fluid. In addition, the interception net component is preferably electrically connected with a control system of the gate 4, a trigger signal of the interception net component can be generated by a control instruction of the gate 4, the interception net 8 is released from falling after being packaged and fixed at the top of the inner side of the pipeline, and tensioning control of the interception net 8 is completed after the interception net is falling.
When the train needs emergency stop, a trigger signal is given, the interception net 8 drops after being unpackaged from the top of the pipeline, meanwhile, the winch 9 of the brake 10 rotates, the interception net 8 is tightened, and the net center is aligned with the central line of the pipeline and perpendicular to the track center. When the magnetic levitation train 1 collides with the interception net 8, the shearing separation pin connected with the interception net 8 and the brake 10 is sheared and broken, the net body screens the magnetic levitation train and slides forward together with the train, the braking net belt is taken out, and then the rotor of the brake 10 is driven to move. After that, the rotor generates braking moment under the rapid rotation, and gradually absorbs the kinetic energy of the maglev train 1, so that the maglev train 1 is stopped rapidly.
During the actual setting, install a plurality of netted interception subassemblies in vacuum pipe's changeover portion structure, independent interval sets up each other in the pipeline longitudinal direction, and the stop stopping process of magnetic levitation train 1 is accomplished independently each other, carries out the emergency braking of magnetic levitation train 1 in the assistance.
Further, as shown in fig. 3 and 4, the evacuation rescue platform is provided in the preferred embodiment corresponding to the transition section structure, and is provided on at least one lateral side outside the vacuum pipe 3, for example, on both lateral sides as shown in fig. 3. Specifically, the evacuation platform 12 is arranged along the longitudinal extension of the pipeline, one side of the evacuation platform 12 is close to the outer wall surface of the vacuum pipeline 3, and the vacuum pipeline 3 is provided with an evacuation protection door 11, and the evacuation protection door 11 can be communicated with the evacuation platform 12 and a walking platform in the pipeline after being opened, so that passengers can walk from the walking platform to the arrangement area of the evacuation protection door 11, and pass through the evacuation protection door 11 to the evacuation platform 12. Correspondingly, an evacuation step 13 is arranged corresponding to the evacuation platform 12, and can be used for emergency evacuation of evacuation personnel on the evacuation platform 12 and rescue traffic of the rescue personnel.
In actual setting, the evacuation protection door 11 is electrically connected with the air pressure sensor 7, so that the evacuation protection door 11 can be opened only under the condition that the atmospheric pressure is restored in the pipe, namely, the opening of the evacuation protection door 11 depends on the display result of the air pressure sensor 7.
When the magnetic levitation pipeline is in fault and needs emergency stop, the magnetic levitation train 1 is guided to a transition section structure of a nearby area, and the gates 4 at two ends of the transition section structure are closed to form a pipeline unit with two closed ends. After that, the air break valve 6 is opened, so that the blocking net assemblies are opened while the air bags are formed to promote the braking of the train, and the blocking net assemblies synchronously work to assist in completing the emergency braking of the maglev train 1. After the magnetic levitation train is braked and stopped in an emergency, the oxygen mask rapidly falls down in the train body, after the air pressure sensor 7 in the transition section structure detects that the pipeline returns to normal pressure, the evacuation protection door 11 is opened, passengers escape from the magnetic levitation train 1 and enter the evacuation platform 12, and the passengers walk to a safe zone through the evacuation ladder 13, so that the emergency evacuation and emergency rescue processes are completed.
It can be understood that when the magnetic levitation train 1 finds that emergency braking is needed, the linear motor starts braking operation, the position of a section where the magnetic levitation train 1 is likely to stop in an emergency is judged, the corresponding gate 4 to be closed is determined, once the magnetic levitation train 1 enters the section, the gates 4 at the two ends are rapidly closed, and then the processes of air breaking ventilation, interception net component interception and the like are performed, so that the magnetic levitation train 1 can be accurately braked in a pipeline unit; finally, after the air pressure in the pipeline unit is recovered, passengers on the maglev train 1 get off and travel to the nearby evacuation rescue platform, so that the emergency evacuation of the passengers is completed.
Preferably, in the transition section structure, the gate 4 is preferably arranged in a plurality of longitudinally spaced mode, namely, at least one gate 4 is additionally arranged in the extending direction of the pipeline unit formed by the two gates 4 at the front end, and a broken air valve 6 and an air pressure sensor 7 are arranged corresponding to the pipeline area corresponding to the additional gate 4. When the pipeline unit at the front end forms and starts emergency braking of the maglev train 1, the additional gate 4 can be synchronously closed, and air is broken in the corresponding area, once the emergency braking pipeline unit is found to be incapable of meeting braking requirements, the gate 4 at the tail part of the pipeline unit is opened to prolong the braking length of the pipeline unit, so that rigid collision between the maglev train 1 and the gate 4 is avoided, and the safety of emergency braking is ensured.
The magnetic levitation pipeline transportation disaster prevention rescue evacuation transition section structure can form a pipeline unit with two closed ends and a certain length in the vacuum pipeline, realize auxiliary emergency braking of the magnetic levitation train in the pipeline unit, meet the requirement of emergency braking after the magnetic levitation train fails, provide conditions for emergency evacuation of passengers on the train after the emergency braking, ensure the safety and reliability of the magnetic levitation operation of the vacuum pipeline, promote the development of pipeline magnetic levitation transportation technology, and have good practical value and application prospect.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
