Excrement storage system special for toilet during passenger train stopping

Abstract

The invention relates to an excrement storage system special for a toilet during passenger train stopping. The excrement storage system comprises a switch system, an electric drive system, a squat pan, a lower communication pipe, a excrement storage device outlet, a clutch, a toilet door and a train bottom excrement collector. The excrement storage system has the advantages that the problem that passengers cannot use the toilet when a passenger train stops is solved, the excrement of the passengers can be collected and discharged through the train bottom excrement collector, environment protection and water saving are achieved, and water used for washing the vacuum excrement collector each time is only 1 / 20 of the water used by a common household toilet bowl; the system changes an originaldirect-discharge blowdown system, zero emission in the whole journey of the passenger train can be achieved, the excrement can be sterilized in a centralized manner after the passenger train arrives,the collected excrement is delivered to related factories for waste utilization and can be used for producing organic waste, green and ecological railways are achieved and comfortable traveling environments are provided for the passengers, and passengers' trouble caused by toilet closing is avoided.

Description

technical field [0001] The invention relates to the field of passenger trains, in particular to a special toilet storage system for toilets when a passenger train stops at a station. Background technique [0002] Most of the toilets on the known passenger trains are directly connected to the outside world, and the feces of the toilets are directly discharged onto the rail subgrade without any treatment. When the speed of the passenger train is high, the dirt in the toilet will disintegrate, but when the speed is slow It will pollute the environment, so passenger trains will close the toilet when they are on the platform or close to the urban area, which will cause great trouble for passengers to go to the toilet. Because passenger trains in China and most developing countries use this direct The row-type design, although its operating cost is low, has the disadvantage that feces are discharged on the train track, which is easy to infect diseases. According to expert statisti...

Problems solved by technology

[0002] Most of the toilets on the known passenger trains are directly connected to the outside world, and the feces of the toilets are directly discharged onto the rail subgrade without any treatment. When the speed of the passenger train is high, the dirt in the toilet will disintegrate, but when the speed is slow It will pollute the environment, so passenger trains will close the toilet when they are on the platform or close to the urban area, which will cause great trouble for passengers to go to the toilet. Because passenger trains in China and most developing countries use this direct The row-type design, although its operating cost is low, has the disadvantage that feces are discharged on the train track, which is easy to infect diseases. According to expert statistics, based on the calculation of 0.5 kg of feces and 1.5 kg of urine per person per day, the country throws 0.5 kg of feces and 1.5 kg of urine every day on both sides of the railway. The amount of feces and urine is at least 3,000 tons. Such a huge amount of feces is torn into endless fine mist particles by the wheels and strong airflow due to the speeding train, and spreads around with the airflow. Hookworms, roundworms, tapeworms, schistosomes... and hepatitis, especially Most of the parasitic diseases in the human body are related to feces. Most of the parasitic diseases are transmitted through feces. If the passenger train does not have a vacuum toilet, the excrement will go straight to the rails, so close the toilet when stopping halfway to avoid At polluted stations, trains with toilets, such as express trains and EMUs, will not close the toilets at halfway stops, and they can be used normally. At present, there are 40,000 passenger trains in the country, and each passenger train has at least 30 toilets. 1.2 million toilets urgently need to be remodeled. After the statistics were exposed by the relevant media, the problem of direct excrement discharge on passenger trains has once again aroused widespread concern in the society.
