Subway vehicle body and roof drainage system thereof

Abstract

The invention discloses a subway vehicle body and a roof drainage system thereof. The roof drainage system of the subway vehicle body comprises continuous rain eaves, air conditioner mounting platformdrainage structures, end wall drainage structures and a cab end drainage structure. The air conditioner mounting platform drainage structures are respectively mounted at four corners of a sunk air conditioner mounting platform; directions of first water inlets are parallel to the vehicle running direction, heights of first water outlets are lower than those of the first water inlets, and the first water outlets are communicated with the rain eaves. The end wall drainage structures are arranged on the heads, at the end walls, of the rain eaves and have drainage passages from top to bottom. Thecab drainage structure is provided with a drainage passage to drain water in the rain eaves to the vehicle bottom or the front of cab doors. In application of the roof drainage system, inertia forceand dead weight of water during acceleration and deceleration of the vehicle is utilized to guide water into the drainage structure to be drained, and thus drainage effect is thorough. Besides, the drainage pipeline is flushed through inertial force and dead weight of water so that blocking risk of the drainage pipeline due to dust accumulation is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, more specifically, to a subway vehicle, and also to a roof drainage system for a subway vehicle. Background technique [0002] Compared with EMUs and ordinary passenger cars, subway vehicles have a large number of passenger compartment doors, which is one of their main characteristics. In order to prevent passengers from being drenched by rainwater when getting on and off the car and passing through the door, a rain eaves mechanism is usually provided above the door to guide and discharge water to the non-door area. EMUs and other vehicles have fewer doors, so it is generally sufficient to set a shorter rain eaves above the doors. However, there are many doors in subway vehicles, so it is usually necessary to set up long rain eaves to discharge from both ends of the vehicle, or directly set up a drainage mechanism on the air-conditioning installation platform to pass through the gap betwee...
