Automatic locking and disengaging water feeding method for passenger train

Abstract

The invention discloses an automatic locking and disengaging water feeding method for a passenger train, wherein the automatic locking and disengaging water feeding method comprises the following steps that: S1, a locking structure, a water stopping structure and a spring structure are arranged in a water feeding pipe connector, the locking structure is used for locking a train water injection nozzle, the water stopping structure can move between a closed position and a conducting position, and under the action of the spring structure, the initial state of the water stopping structure is in a closed position; S2, a water supply worker sleeves the train water injection nozzle with a water supply pipe connector, the train water injection nozzle extrudes the water stopping structure so as to extrude the water stopping structure from the closed position to the conduction position, and meanwhile, the spring structure stores elastic force; S3, the water supply worker adjusts the locking structure, so that the water supply pipe connector and the train water injection nozzle are locked, and then water supply is started; S4, after water supply is completed, the locking structure is adjusted again, so that the water supply pipe connector and the train water injection nozzle are loosened; and S5, the spring structure releases the elastic force, so that the train water injection nozzle automatically falls off, and the water stopping structure returns to the closed position from the conduction position.

Description

technical field [0001] The invention relates to the field of train water supply, in particular to a method for automatically locking and detaching passenger trains for water supply. Background technique [0002] At present, after the passenger train enters the station, the operation of adding water to the carriages needs to be completed manually. The main steps include: before the water is filled, the water supply staff connects the rubber water guide pipe of the ground well to the cone-shaped water injection nozzle on the car body, and then opens the water supply valve. Water; after the water supply is completed, the water supply staff will close the water supply valve, and then manually pull out the water guide pipe. The disadvantages of this water supply method are as follows: First, it is difficult to achieve fastening and connection. There are various types of conical water injection nozzles for passenger trains, and the size of the nozzle of the ground aqueduct is rela...

AI Technical Summary

Problems solved by technology

The disadvantages of this water supply method are as follows: First, it is difficult to achieve fastening and connection. There are various types of conical water injection nozzles for passenger trains, and the size of the nozzle of the ground aqueduct is relatively fixed, so it is troublesome to connect, and it is difficult to achieve a good fit. Second, due to the troublesome matching and the tight time for water filling, the psychological burden on the water crew is heavy, and the labor intensity of taking over is high; the third is that it is difficult to quickly realize the locking and separation of the water injection nozzle and the joint, so the auxiliary time required long, it is difficult to provide sufficient water for passenger cars; fourth, the speed of water supply is difficult to control, and water leakage may occur, resulting in a large waste of water
