Abstract

The invention provides an apparatus of oxygen supply for rail vehicles and the method of supplying oxygen and aims at the condition that a carriage has a low concentration of oxygen caused by thin air in plateau areas. The invention adopts an integral oxygen producing device and comprises air sending pipes which are connected with the inside of the vehicle through oxygen supplying pipes and auxiliary distributed oxygen supplying branch pipes according to the distribution of personal quota in the carriage. The whole environment of the inner of the carriage is provided with high concentrated oxygen, and oxygen supplying is available to all the passengers at the same time. The invention realizes an oxygen supply mode which combines the diffusion type of oxygen supply and the distribution type of oxygen supply. The produced oxygen can be distributed in the whole environment of the inner of the carriage uniformly, solving the oxygen inhalation requirement of all the passengers. The apparatus of oxygen supply for rail vehicles comprises the integral oxygen producing device in the inside of the vehicle, the oxygen supply pipes of the oxygen producing device, air the air sending pipes connected with the inside of the vehicle and the auxiliary distributed oxygen supplying branch pipes according to the distribution of personal quota in the carriage.

Description

technical field [0001] The invention relates to an in-vehicle oxygen supply device and method for a rail vehicle operating on a plateau, belonging to the field of machinery manufacturing. Background technique [0002] With the rapid development of urban rail transit, the structural design of the car body and interior facilities is more humanized. Rail vehicles used in plateau areas operate in harsh external environments, and the oxygen concentration and temperature inside the compartments are low. Even strong passengers often suffer from altitude sickness. In order to relieve the worries of passengers traveling on high altitudes and establish an emergency situation in response to passengers' physical discomfort, emergency oxygen supply devices are usually equipped on plateau trains. [0003] Existing common oxygen supply device is the oxygen generating device of single structure, just this device is provided to this passenger to use by the flight attendant when a certain pa...
