The invention discloses a fireproof plugging device for a railway vehicle drainage port. The device comprises a fixing mechanism which is detachably and fixedly connected to the outer surface of a pipe wall of the railway vehicle drainage port, a circulation channel which penetrates through the fixing mechanism, is communicated with the railway vehicle drainage port and is used for discharging fluid flowing out of the railway vehicle drainage port, and a fireproof expansion piece which is arranged in the fixing mechanism, when the fireproof expansion piece is heated, the fireproof expansion piece expands to block the circulation channel, and therefore when a railway vehicle runs forwards, fluid flowing out of the railway vehicle drainage port can flow out through the circulation channel, normal drainage is not affected, and when the lower portion of the vehicle body is on fire, the fireproof expansion piece can be heated to expand to block the circulation channel; therefore, flames andsmoke can be prevented from spreading into a carriage through the railway vehicle drainage port, and the safety performance is improved. Certainly, the risk that a fireproof material is added to theinner side of the railway vehicle drainage port, and consequently sundries block the railway vehicle drainage port is avoided.

    本发明公开了一种用于轨道车辆排水口的防火封堵器,包括:固定机构,可拆卸式固定连接于轨道车辆排水口的管壁外表面上;流通通道,贯穿固定机构,且与轨道车辆排水口连通,用于将从轨道车辆排水口流出的流体排出;防火膨胀件,设置于固定机构中,在受热时,防火膨胀件膨胀以堵塞流通通道,就此,在轨道车正行运行时,从轨道车辆排水口流出的流体会通过该流通通道流出,不影响正常排水,而在车体下方起火时,防火膨胀件会受热膨胀,以堵塞流通通道,从而可避免火焰及烟气通过该轨道车辆排水口蔓延至车厢内部,也就提高了安全性能。当然,也就避免了在该轨道车辆排水口的内侧增加防火材料、以及由此导致的杂物堵住轨道车辆排水口的风险。
