Spray Device to be Mounted on an Electric Vehicle
First Claim
1. A spray device which is mounted on an electric vehicle in order to improve air quality in a subway tunnel, the spray device comprising:
- a water supply port disposed at one side of a doorway of a trailer car (T-car) on which the spray device is mounted, the water supply port being supplied with water using a water supply gun at a platform (A) of a subway station;
a water supply tank which contains the water therein, the water supply tank having partition plates therein;
a compression motor and a pump which supply pressurized water to the spray device;
distribution pipes which guide the pressurized water so that the pressurized water is automatically sprayed to a road and both sides of the subway tunnel and to a surface of ground rails;
spray nozzles disposed in the distribution pipes to spray the pressurized water to the road and both sides of the subway tunnel and to the surface of ground rails;
a pressure adjustment valve for adjusting the pressurized water supplied to the spray nozzles to a proper pressure;
automatic valves disposed on the distribution valves at front ends of the spray nozzles; and
a control panel which controls the automatic valves, the compression motor and the pump based on operations of a plurality of sensors and a control unit which are provided in the spray device,wherein the spray device operates in real time to spray the pressurized water through the spray nozzles by supplying the pressurized water through the automatic valves and the distribution pipes while the electric vehicle is driving.

Abstract
A spray device mounted on a non-motor vehicle (T-car) selected from among commercial or novel electric vehicles so as to improve air quality inside a tunnel by spraying water during operation, collecting pollutants floating inside a subway tunnel, and collecting and sinking fine dust generated by means of the operation of a train onto the road. 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.
