The invention discloses an overspeed warning device for rail transit, which comprises an electric passenger car; an accompanying spray washing device which is arranged at the top end of the electric passenger car, is used for spraying and washing glass at the front end of the electric passenger car when the electric passenger car stops at a station every time; a high-speed alarm device which used for giving an alarm in real time when the electric passenger car is in an out-of-control high-speed condition, and is arranged at the top end in the electric passenger car. Through convection wind pressure generated when the electric passenger car runs and the elastic force effect of a wind pressure spring, the accompanying cleaning function of the front end glass of the electric passenger car is achieved through the air pressure difference and the extrusion force, through dynamic changes of wind pressure generation and disappearance, the front end glass can be cleaned once every time station parking is conducted, and in addition, through the pressure effect on convection wind and the structural arrangement of a wind pressure rotating piece and an abutting wheel, the overspeed alarm function under the high-speed wind pressure effect is achieved through reciprocating knocking, the safety of passengers is guaranteed, and early warning is conducted on a driver under the condition that the speed is abnormal.
本发明公开了一种轨道交通用超速警示装置,包括电客车,用于在每次停在站点对电客车前端玻璃时进行喷洗的伴随喷洗装置设置于所述电客车的顶端,用于在电客车是失控高速情况下进行实时报警的高速报警装置设置于所述电客车的内部顶端。本发明通过电客车行驶时的对流风压和风压弹簧的弹力作用,利用气压差与挤压力实现了对电客车前端玻璃的伴随性清洗功能,通过风压产生与消失的动态变化,使得每次进行站点停车时都能进行一次前端玻璃的清洗,此外,通过对流风的压力作用,以及风压转片与抵触轮的结构设置,利用往复敲击实现对在高速风压作用下的超速报警功能,保障了乘客的安全性,并在速度异常情况下对驾驶员进行预警。
