The present invention relates to a spray device to be mounted on an electric vehicle, and more particularly, to a spray device to be mounted on a non-motor vehicle (T-car) selected from among commercial or novel electric vehicles so as to substantially improve air quality in a tunnel by spraying water during operation, collecting pollutants floating in a subway tunnel, and collecting and sinking fine dust generated by means of the operation of a train onto the road. According to the present invention, the spray device is mounted on a lower portion of the non-motorized vehicle (T-car) from among commercial or new electromotive cars, pressurized water is supplied to a distribution pipe on a discharging side by means of a pressurizing motor and a pump, and a jet is sprayed through a spray nozzle coupled to the distribution pipe. Also, it is possible to automatically spray a jet onto a rail surface while a train moves on a ground-level railway using a sensor and a control board. |
