Fixing structure for sewage discharging hose of passenger train

Abstract

The invention provides a fixing structure for a sewage discharge hose of a passenger train. The fixing structure comprises a hose storage well chamber and a sewage discharge main pipe, a hose basket is arranged in the hose storage well chamber, a sewage discharge hose is placed in the hose basket, the sewage discharge main pipe penetrates through the hose storage well chamber, one end of the sewage discharge hose is communicated with the sewage discharge main pipe, the other end of the sewage discharge hose is provided with a sewage discharging connector capable of being communicated with a train sewage box, and the sewage discharging connector is fixed to the inner wall of the hose basket. The sewage discharge hose is stored in the hose basket of the storage well chamber, the hose rewinding workload of sewage discharging operation is reduced, the situation that the operation efficiency is reduced due to tripping of the sewage discharging hose and a hose winder is avoided, the hose bending frequency is reduced, and the potential safety hazard that the sewage discharging hose is scattered due to non-rewinding after operation is solved.

Description

technical field [0001] The invention relates to the technical field of railway equipment, in particular to a fixing structure for a sewage discharge hose of a railway passenger car. Background technique [0002] The usual railway passenger car sewage discharge system includes sewage discharge vacuum pump room, sewage discharge pipeline and accessories, sewage discharge unit, electric control system, etc. The sewage discharge vacuum pump room provides stable negative pressure for the sewage discharge pipeline; the sewage discharge pipeline, vacuum gauge, valve and other accessories pump the train sewage to the pump room; the sewage discharge unit is used for the sewage discharge operation to the train, including sewage discharge joints, soft Pipes, valves, etc.; the electric control system is used for functions such as recovery of sewage discharge hoses. [0003] At present, the hoses of the sewage unloading unit of railway passenger cars are mainly of the rewind type, and t...

AI Technical Summary

Problems solved by technology

[0009] At present, the sewage unloading unit needs to be equipped with a hose reel to rewind the sewage discharge hose. The traditional electric rewind hose has problems such as high failure rate and heavy maintenance workload. Therefore, there is an urgent need for a hose fixing method for the sewage discharge unit to solve the current Problems with the rewinding of the sewage discharge hose
