A high-speed EMU drainage device

Abstract

The invention provides a drainage device for a high-speed motor train unit. The drainage device comprises a water collecting container and a drainage pipeline. The water collecting container comprises a shell and a cavity in the shell. The interior of the cavity is divided into a drainage cavity and a water inflow cavity through a partition plate. The drainage cavity and the water inflow cavity communicate with each other through a siphon installed on the partition plate. The top of the water inflow cavity is connected with a water inflow pipe. The top of the drainage cavity communicates with a drainage pipe inlet of the drainage pipeline through a water inflow pipe joint. The drainage pipeline is located outside the water collecting container. A drainage pipe outlet in the tail end of the drainage pipeline is located below the horizontal plane of the bottom of the water collecting container. By the adoption of the drainage device for the high-speed motor train unit, the structure is simple, washing wastewater can be effectively stored, and a low weight purpose can be achieved.

Description

technical field [0001] The invention relates to a drainage device, in particular to a drainage device suitable for high-speed EMUs. Background technique [0002] EMUs, urban rail and subway trains generally have washrooms, and the waste water in the washrooms is directly discharged out of the train through the drainage device installed under the train, such as figure 1 As shown, the interior of the drainage device is divided into a drainage chamber and a water inlet chamber, and the penetration and drainage are realized through the siphon tube. The drainage pipes are directly installed in the drainage chamber to discharge the waste water from the bottom of the drainage chamber. However, due to space constraints, the drainage The device is generally small in size, and the drainage pipeline is also placed, which further leads to the reduction of the effective volume of the drainage cavity. Therefore, the drainage device generally cannot effectively store waste water and must b...

[0002] EMUs, urban rail and subway trains generally have washrooms, and the waste water in the washrooms is directly discharged out of the train through the drainage device installed under the train, such as figure 1 As shown, the interior of the drainage device is divided into a drainage chamber and a water inlet chamber, and the penetration and drainage are realized through the siphon tube. The drainage pipes are directly installed in the drainage chamber to discharge the waste water from the bottom of the drainage chamber. However, due to space constraints, the drainage The device is generally small in size, and the drainage pipeline is also placed, which further leads to the reduction of the effective volume of the drainage cavity. Therefore, the drainage device generally cannot effectively store waste water and must be discharged at any time. In order to ensure air tightness, the drainage device generally only has one drain. It is not easy to maintain when the pipe outlet is clogged, and it is not easy to achieve the purpose of reducing the weight of the car body
