Water-filling self-closing device for railway train

Abstract

The invention discloses a water-filling self-closing device for a railway train. The watering self-closing device comprises a train water storage tank, a transmitter and a receiver, wherein a water injection tube and a water overflow port are arranged on the train water storage tank; the water overflow port is connected with a vertically downward water overflow tube; a water-filling tube is closely sleeved on the water injection tube; the transmitter comprises a seesaw composed of a support and a plate body connected with the support via a pin shaft, and a wireless transmission module provided with a control contact at the bottom end; one end of the plate body is arranged below the water overflow tube, and the other end of the plate body is provided with a bulged part in a corresponding position below the control contact; the receiver comprises an electromagnetic valve arranged on the water-filling tube and used for opening or closing a water channel in the water-filling tube, a control module connected with the electromagnetic valve and used for controlling the close of the electromagnetic valve, and a wireless reception module connected with the wireless transmission module and the control module respectively. The water-filling self-closing device disclosed by the invention is simple in structure, convenient and practical, and can be used for closing the water channel to stop water-filling in time after the tank is fully filled with water, thus saving water and reducing economic losses.

Description

technical field [0001] The invention relates to an automatic water closing device for railway trains. Background technique [0002] Railway trains are an important means of transportation for people to travel. Domestic water for railway trains is completed by arranging water supply operations at passenger train stations. At present, the water supply operations for railway trains usually use the following methods: manually hold the water supply pipes to connect with the train water injection pipes, open Water supply valve, start water supply. When the train water tank is full of water and see water overflowing from the overflow port of the train water tank, the water supply engineer will close the water supply valve. Since there are many railway train cars, the water supply engineer needs to complete Connecting the water supply pipe, opening the water supply valve, closing the water supply valve when the water is full and overflowing, taking care of the front and back, the wo...

[0002] Railway trains are an important means of transportation for people to travel. Domestic water for railway trains is completed by arranging water supply operations at passenger train stations. At present, the water supply operations for railway trains usually use the following methods: manually hold the water supply pipes to connect with the train water injection pipes, open Water supply valve, start water supply. When the train water tank is full of water and see water overflowing from the overflow port of the train water storage tank, the water supply engineer closes the water supply valve. Since there are many railway train cars, the water supply engineer needs to complete Connecting the water supply pipe, opening the water supply valve, closing the water supply valve when the water is full and overflowing, taking care of the front and back, is overwhelming, the operation is cumbersome, labor-intensive, and often causes the water tank of the train to overflow after a certain period of time before closing the water supply valve , when the inventor made a social investigation on this phenomenon at Beijing Railway Station at 6:30 on May 22, 2013, he saw that the water storage tanks of several trains were filled with water and overflowed outwards at the same time, and the running water flow splashed to the ground, and the water splashed far away. It was more than one meter away, and it took 19 minutes to see the water supply workers complete the water supply valves of each carriage gradually closing one by one, resulting in a cruel waste of tap water
