The invention relates to the technical field of railway vehicles, in particular to a ventilation device for railway vehicles, which comprises a ventilation pipe, air outlet blades are rotatably connected to the inner wall of the ventilation pipe through bearings, a cavity is formed in the ventilation pipe, a gear is arranged at one end, located in the cavity, of each air outlet blade, and a first hydraulic cylinder is fixed to the inner wall of the cavity through bolts; a toothed plate is fixed to the output end of the first hydraulic cylinder through a bolt and meshed with the gear, a guide plate is fixed to the inner wall of the cavity through a bolt, and the toothed plate is slidably connected to the outer portion of the guide plate. The air conditioner has the beneficial effects that the first hydraulic cylinder is started to drive the toothed plate to move, the toothed plate can be meshed with the gear, the gear impacts the air outlet blades to turn over, the air inlet direction can be adjusted, the problem that direct blowing can only be conducted in one direction, and consequently part of passengers are blown all the time is solved, and the comfort degree is better; and the sliding block can drive the cleaning brush to move to clean the screen plate.
本发明涉及轨道车辆技术领域,具体是一种轨道车辆用通风装置,包括通风管,通风管的内壁上通过轴承转动连接有出风叶,且通风管的内部设置有空腔,出风叶位于空腔内部的一端设置有齿轮,空腔的内壁上通过螺栓固定有第一液压缸,且第一液压缸的输出端上通过螺栓固定有齿板,齿板与齿轮互相啮合,空腔的内壁上通过螺栓固定有导向板,且齿板滑动连接在导向板的外部。本发明的有益效果:启动第一液压缸带动齿板移动,能够使齿板与齿轮啮合,使得齿轮打动出风叶翻动,可以对进风的风向进行调整,解决了只能对一个方向直吹导致部分乘客一直吹风的问题,舒适度更佳,马达带动丝杆转动与滑块螺纹时,能够使滑块带动清扫刷移动对网板进行清扫。
