Abstract

The invention discloses a railway vehicle and a railway vehicle ventilating device. The railway vehicle ventilating device comprises an air inlet cylinder, a first air opening and a second air openingare formed in the side faces of the air inlet cylinder, a top air opening is formed in the top of the air inlet cylinder, an air outlet is formed in the bottom of the air inlet cylinder, the first air opening and the second air opening are oppositely formed, and in a free state, the top air opening, the first air opening, the second air opening and the air outlet communicate; a first flow-guidingplate, a second flow-guiding plate and a connecting rod hinged between the first flow-guiding plate and the second flow-guiding plate are arranged in the air inlet cylinder, the top of the first flow-guiding plate is hinged to the position, on the upper part of the first air opening, of the air inlet cylinder, the top of the second flow-guiding plate is hinged to the position, on the upper part of the second air opening, of the air inlet cylinder, the first flow-guiding plate and the second flow-guiding plate constitute a trapezoidal connecting rod structure through the connecting rod, the upper end of the trapezoidal connecting rod structure is a large-diameter end, and the second flow-guiding plate can swing to the state of sealing the second air opening. According to the railway vehicle ventilating device, the angle between each flow-guiding plate and the corresponding air opening is adjusted according to the change of the vehicle speed, and the ventilating quantity can be ensuredduring high-speed operation of the vehicle.

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 ...
