Description
Technical Field
The invention belongs to a vacuum pipeline traffic system, and particularly relates to a vacuum pipeline train with a pressure-relief fire-extinguishing system.
Background
The main resistance of the high-speed train running in the dense atmosphere on the earth surface is air resistance, which limits the speed increase and also forms huge energy consumption. Theoretically, in order to increase the running speed and reduce the running energy consumption, a track on which a train runs can be placed in a pipeline, the pipeline is vacuumized, and the train runs in a vacuum pipeline, so that the vacuum pipeline train is called as a vacuum pipeline train.
From the engineering practice point of view, the vacuum pipeline is not in a complete vacuum state, air with extremely low pressure still exists in the pipeline, but because the air pressure is extremely low and the oxygen content is extremely thin, a fire disaster cannot happen in the pipeline. However, air with nearly one atmospheric pressure exists in each carriage of the train to maintain the life activities of passengers and drivers and passengers, the materials such as seats, interiors and the like in the train are difficult to be completely incombustible, the train is used as a complex electromechanical system, complex electrical equipment is designed in the train, fire disasters in the train are possibly caused due to aging or other faults of the electrical equipment, and the passengers are difficult to escape when the train runs in a pipeline and the fire disasters occur unlike the train running in an open atmospheric environment. When a fire breaks out in a certain carriage of the train, passengers can evacuate to the adjacent carriages in a short time, but if the fire of the carriage can not be controlled in time, the fire affects the structural strength of the carriage or the fire spreads to other carriages, and finally the safety problem of the passengers can also be caused.
Because the air in the vacuum pipeline in which the train is located is extremely thin, the breathing of passengers in the train and the heating of the passengers and vehicle-mounted electrical equipment are problems to be solved.
At present, trains running in atmospheric environment, such as high-speed rails and subway vehicles, are equipped with handheld fire extinguishers in each carriage, and spraying fire extinguishing systems are designed on part of foreign trains.
Referring to fig. 3 and 4, the sprinkler system includes a roof-mounted spray head 111, a water pipe 112, a water supply pump 113, and a water tank 114. When a fire breaks out in the passenger compartment 109, the smoke alarm system or the manual operation spraying system sprays water into the compartment to extinguish the fire.
The existing spraying fire-extinguishing system of the high-speed train has the following defects: the spray fire-extinguishing system used on the high-speed train needs fire-fighting water carried by the train, and the water carrying amount is limited, so that the fire in the carriage can not be completely extinguished by the vehicle-mounted spray fire-extinguishing system, and the train can be stopped at any time for evacuating people even if the fire can not be completely extinguished by the train running in the atmospheric environment. However, the train running in the vacuum pipeline has high speed and long parking time, people can be evacuated after the train is parked and the atmospheric pressure in the pipeline is recovered, when a fire in the train is not extinguished, the fire of the train can be aggravated if the atmospheric pressure in the pipeline is recovered, smoke in the pipeline cannot be dissipated, and therefore the people cannot escape through the pipeline. It is therefore desirable that the fire fighting modes of trains operating in vacuum lines ensure complete suppression of fires in the cars, which conventional water-spraying fire fighting modes used on high-speed rails obviously do not meet.
In addition, in order to avoid the increase of the self weight of the train, an oxygen supply and temperature regulation system which is mutually associated with the fire extinguishing system needs to be designed for the vacuum pipeline train, and the systems can act in a coordinated way and share the water resource.
