Air pressure fastening connecting type water supply automatic control system for passenger train

Abstract

The present invention is an automatically controlled pneumatically fastened water supply system for passenger train. Structurally, the automatically controlled pneumatically fastened water supply system includes pneumatically fastened fast pipe union connected between the water injecting nozzle in the train and the water pipe; one T-pipe with the first end connected to the water pipe, the second end connected via water pipe and the first solenoid valve to the water source, and the third end connected via air pipe and the second solenoid valve to a micro air pump; the air pipe connected to the air passage of the pneumatically fastened fast pipe union, and a control device comprising one microcomputerized control unit and one radio emitter. The present invention has short water supply time, water saving, high work efficiency and other advantages.

Description

Technical field [0001] The invention relates to a water supply device for passenger trains, in particular to an air pressure fastening connection type automatic water supply control system for passenger trains. Background technique [0002] At present, most of the water supply operations on railway passenger trains in my country still use the operation method that has lasted for decades-after the train stops, the water supply worker connects the water pipe to the train water injection nozzle, and then runs for a certain distance to turn on the water valve to supply water; the water valve before driving Close, and then return to the car body to separate the water pipe from the car body. There are many shortcomings in this operation method, mainly as follows: [0003] 1. The operation efficiency is low, and the water supply capacity of the existing water supply pipe network equipment has not been fully utilized. After the speed of the train is increased, the water supply / demand con...

AI Technical Summary

Problems solved by technology

[0003] 1. The operating efficiency is low, the water supply capacity of the existing water supply pipe network equipment has not been fully utilized, and the water supply / demand contradiction of related passenger trains has become more and more prominent after the train speed is increased

[0004] 2. Serious waste of water resources

[0005] 3. Sheungshui is labor-intensive and labor-intensive

[0006] 4. The waterlogging formed by residual water or overflow water will soak the roadbed for a long time to reduce its performance and affect other operations
