摘要：【中文】本发明涉及一种列车用集便系统的重力排污机构及真空集便系统，包括中转箱和污物箱，所述中转箱置于污物箱的上方，所述中转箱与污物箱之间通过连通口连通，在所述连通口处安装有用于控制连通口通断的阀门，所述阀门为塞阀或膜片阀，所述中转箱通过重力将污物排至污物箱内。本发明整体结构简单，可以不限制连通口的口径，而且利用塞阀或膜片阀代替现有技术中的滑板阀，不但可以使得重力排污更加稳定可靠，而且有利于降低维护成本。 【EN】The invention relates to a gravity sewage draining mechanism of a train excrement collecting system and a vacuum excrement collecting system, which comprise a transfer tank and a sewage tank, wherein the transfer tank is arranged above the sewage tank, the transfer tank is communicated with the sewage tank through a communication port, a valve for controlling the communication port to be opened and closed is arranged at the communication port, the valve is a plug valve or a diaphragm valve, and the transfer tank discharges sewage into the sewage tank through gravity. The invention has simple integral structure, can not limit the caliber of the communicating port, and utilizes the plug valve or the diaphragm valve to replace a sliding plate valve in the prior art, thereby not only leading the gravity sewage discharge to be more stable and reliable, but also being beneficial to reducing the maintenance cost.

摘要：【中文】本发明涉及一种扩展方舱，包括固定舱体，在所述固定舱体的一侧或两侧安装有可抽拉的一个或多个扩展舱体，在所述固定舱体的底部设置有可使扩展舱体移动至固定舱体外部的多个滑轨，所述滑轨包括设置在固定舱体内部的固定滑轨及对应设置在所述固定舱体外侧的活动滑轨，所述活动滑轨的另一端安装有支撑地脚，所述活动滑轨被配置成在展开状态时与对应的固定滑轨共同形成供扩展舱体移动的滑轨而在所述扩展舱体处于缩回状态时缩回固定在所述固定舱体上。本发明不但可以大幅提升扩展舱体在展开状态时的承载能力，有利于增加扩展空间的抽拉长度，有效提升扩展空间，而且，整体结构简单，操作也简单方便，抽拉过程平稳性也更好。 【EN】The invention relates to an expansion shelter, which comprises a fixed cabin body, wherein one or more expansion cabin bodies capable of being pulled out are installed on one side or two sides of the fixed cabin body, a plurality of slide rails capable of enabling the expansion cabin bodies to move to the outside of the fixed cabin body are arranged at the bottom of the fixed cabin body, each slide rail comprises a fixed slide rail arranged in the fixed cabin body and a movable slide rail correspondingly arranged on the outside of the fixed cabin body, supporting feet are installed at the other ends of the movable slide rails, and the movable slide rails are configured to form slide rails for the expansion cabin bodies to move together with the corresponding fixed slide rails in an expansion state and retract and fix the expansion cabin bodies on the fixed cabin bodies in a retraction state. The invention can greatly improve the bearing capacity of the expansion cabin body in the unfolding state, is beneficial to increasing the drawing length of the expansion space and effectively improving the expansion space, and has simple integral structure, simple and convenient operation and better stability in the drawing process.
