Title:
WATER DRAIN STRUCTURE FOR RAILWAY VEHICLES
Document Type and Number:
WIPO Patent Application WO/2018/020612
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of strengthening fire and smoke prevention measures by preventing, in case of fire, smoke and flames from entering the interior of a railway vehicle through the water drain structure of the railway vehicle. [Solution] Water accumulated within a vehicle interior can be usually discharged to the outside of the vehicle by a water drain pipe 12. A closure means 14 for closing an opening at the lower end 12b of the water drain pipe 12 when subjected to heat from the outside is provided at the lower end 12b of the water drain pipe 12. The closure means 14 is constituted of a box 16 which has an opening 16a formed in a sidewall 163 thereof and which covers at least the lower end 12b of the water drain pipe 12. When the box 16 is subjected to heat having a temperature higher than a predetermined temperature, a shutter section 18 operates by its own weight to close the opening 16a of the box 16. This means that, in case of fire, the closure means 14 closes the opening at the lower end 12b of the water drain pipe 12 when subjected to the heat of the fire, thereby being capable of being more reliably preventing smoke and flames from entering the vehicle interior from the outside through the water drain pipe 12.
