Abstract

The invention discloses a rail vehicle and a ventilation device for a rail vehicle. The ventilation device includes an air inlet tube, the side of the air inlet tube is provided with a first air port and a second air port, the top is provided with a top air port and the bottom is provided with an air outlet, and the first The air outlet and the second air outlet are set opposite to each other. In the free state, the top air outlet, the first air outlet, the second air outlet and the air outlet are connected; The connecting rod between the baffle and the second baffle, the top of the first baffle is hinged on the air inlet cylinder at the position above the first air outlet, the top of the second baffle is hinged on the air inlet cylinder and located at the first At the position above the second air outlet, the first air guide plate and the second air guide plate form a trapezoidal connecting rod structure through the connecting rod and the upper end is a large diameter end, and the second air guide plate can swing to the state of sealing the second air outlet. In the ventilation device, the angle between the deflector and the corresponding air outlet is automatically adjusted according to the change of the vehicle speed, and the ventilation volume can be ensured when the vehicle is running at high speed.

Description

technical field [0001] The invention belongs to the field of rail vehicle ventilation design, in particular to a rail vehicle ventilation device, and in addition to a rail vehicle. Background technique [0002] At present, the air inlet device of the rail vehicle fan is usually installed on the surface of the rail vehicle, such as the roof, side wall, and side suspension beam, and the air inlet surface of the ventilation device is in a negative pressure area. [0003] When the rail vehicle is running, there is a negative pressure difference between the air inlet and outlet of the ventilation branch. The negative pressure difference may be greater than or equal to the fan pressure value, at this time, the ventilation volume is zero. The instability of the air volume of the ventilation branch will directly affect the working state of the components that need ventilation and cooling in the rail vehicle. [0004] Therefore, how to solve the problem that the ventilation device ...
