The invention provides a cubicle with an inflatable sealing structure, which is mounted on a rail transit train body and comprises a cubicle fixing part connected with the train body through a first sealing structure and a top fixing part connected with the cubicle fixing part through a second sealing structure, and the cubicle fixing part comprises a cubicle body and a top fixing plate; the screen cabinet movable part is connected with the screen cabinet fixed part through a second sealing structure, and the screen cabinet movable part comprises a top overhauling plate and a cabinet door; the top fixing plate is further provided with an air inlet valve used for introducing air into the cabinet body and an air outlet valve used for discharging air. According to the screen cabinet with the inflatable sealing structure, the multiple sealing structures are used for sealing all installation gaps of the screen cabinet, and the interior and the exterior of the screen cabinet are isolated as much as possible. And meanwhile, an air inlet valve and an exhaust valve are arranged, so that a positive pressure space is formed in the screen cabinet compared with the outside while air circulation and a heat dissipation function are achieved, the interference of external environment factors on internal working elements is reduced, the operation stability of equipment is improved, and safe operation of a train is ensured.
本发明提供了一种具有充气式密封结构屏柜,安装于轨道交通列车车体上,包括:通过第一密封结构与车体进行连接的屏柜固定部,屏柜固定部包括柜体与顶部固定板;通过第二密封结构与屏柜固定部连接的屏柜活动部,屏柜活动部包括顶部检修板与柜门;顶部固定板上还设置有用于向柜体内部通入气体进气阀与排出气体的排气阀。本发明提供的具有充气式密封结构屏柜,利用多重密封结构将屏柜的各处安装缝隙进行密封,尽可能的做到屏柜内部与外部隔离。同时利用设置有进气阀与排气阀,在做到空气流通发挥散热功能的同时,屏柜内部也相较于外界形成了正压空间,减少了内部工作元件受到外界环境因素的干扰,提升了设备运行稳定性,确保列车安全运行。
