ANTIFREEZING AGENT LIQUID FEEDING DEVICE AND ANTIFREEZING AGENT LIQUID FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an antifreezing agent liquid feeding device and an antifreezing agent liquid feeding method, which allow the antifreezing agent liquid feeding device to be shifted to different positions within the car body or to be shifted from the inside of the car body to the outside, and make it easy to install, shift and remove the antifreezing agent liquid feeding device.SOLUTION: An antifreezing agent liquid feeding device 4 in this invention, which is installed inside a car body 2 of a train car, comprises a coupling-uncoupling mechanism 7 which enables coupling and uncoupling of a liquid-feeding tube 6 through which the antifreezing agent liquid flows towards a spray nozzle 5 provided at the bottom of the car body 2 and the antifreezing agent liquid device 4, and is capable of uncoupling the antifreezing agent liquid feeding device 4 from the liquid-feeding tube 6 by the coupling-uncoupling mechanism 7.SELECTED DRAWING: Figure 2
