Manned transport equipment with breathing air supply pipe

Abstract

The invention discloses manned transport equipment with a breathing air supply pipe. The manned transport equipment is equipped with the breathing air supply pipe. The pipe wall of the breathing air supply pipe is provided with an opening along the length direction of the breathing air supply pipe; pipe walls on both sides of the opening are respectively connected to a chain belt I and a chain belt II; one side edge of the chain belt I is provided with arrayed chain teeth I; one side edge of the chain belt II is provided with arrayed chain teeth II; a ventilation sliding block device is disposed on a joint between the chain belt I and the chain belt II; the structure of the ventilation sliding block device includes two guiding mouths, a bottom plate, a cover plate and inner core bodies; the bottom plate is connected to the cover plate through the inner core bodies; a gap is disposed between the bottom plate and the cover plate; in the outer sides of the guiding mouths of the ventilation sliding block device, the chain teeth I of the chain belt I are meshed with the chain teeth II of the chain belt II; the chain teeth I and the chain teeth II located inside the ventilation sliding block device are opened by the inner core bodies; and the ventilation sliding block device is provided with an air outlet hole.

Description

technical field [0001] The present application relates to a passenger transport device with a breathing air supply tube. Background technique [0002] In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. [0003] When a fire breaks out in passenger transportation equipment such as motor vehicles or ships with breathing air supply pipes, in order to avoid the smoke from invading people, at present, fire rescue personnel mostly rely on the use of fire-fighting air tanks combined with fire masks when rescuing people trapped by fire smoke. However, it is inconvenient to carry fire-fighting air tanks and cannot be used by many people. Sometimes the spare air tanks carried by firefighters cannot satisfy their own rescue use, let alone satisfy the trapped people at the fire scene. Similarly, when a fire occurs in manned transport equipment such as motor vehicles, passenger cars, ships, etc., fire smoke spreads rapid...
