Excrement treatment device for rail transit

Abstract

The invention discloses an excrement treatment device for rail transit. The device comprises a collection box, a water storage partition plate, a water storage cavity, a collection cavity, a pressure sensor, a water injection pipe, a blow-off pipe, an anti-odor funnel, a guide slope plate, a lower suction cylinder, an upper suction cylinder, a discharge cylinder, a storage box, rollers, a handle, a pin, an isolation part, a suction part and a flow guide part; a vertical water storage partition plate is jointly fixed to the front end and the rear end in the collection box, the water storage cavity and the collection cavity are formed between the collection box and the water storage partition plate, and a vertical pressure sensor is fixed to the middle of the bottom end of the water storage cavity. The device is designed by mainly utilizing the speed change of a train, the inertial motion of an object and the energy conservation principle of the object, the anti-odor funnel with the small upper part and the large lower part can prevent odor from overflowing from the blow-off pipe to a certain extent, and the water storage cavity capable of automatically flushing the guide slope plate can enhance the excrement collection effect.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to an excrement treatment device for rail transit. Background technique [0002] At present, the excrement collection methods adopted by the traditional ordinary express trains and high-speed trains in China are not the same. For the traditional ordinary express trains, most of them choose to use the excrement disposal method of direct row, and this excrement disposal method will The excrement is directly discharged into the environment around the railroad track, which not only affects the appearance, but also causes a series of health and safety problems, and the excrement accumulates near the railroad track for a long time and then penetrates into the interior of the gate, thereby dispelling the ballast between ballasts. The gap is filled, and then the shock absorption effect of the barrier gate is reduced. For the high-speed rail, most of the excrement treatment method is vacuumed. T...

[0002] At present, the excrement collection methods adopted by the traditional ordinary express trains and high-speed trains in China are not the same. For the traditional ordinary express trains, most of them choose to use the excrement disposal method of direct row, and this excrement disposal method will The excrement is directly discharged into the environment around the railroad track, which not only affects the appearance, but also causes a series of health and safety problems, and the excrement accumulates near the railroad track for a long time and then penetrates into the interior of the gate, thereby dispelling the ballast between ballasts. The gap is filled, and then the shock absorption effect of the barrier gate is reduced. For the high-speed rail, most of the excrement treatment method is vacuumed. ballast, and reduce the health pollution along the railway, but the fly in the ointment is the high cost, which highlights the shortcomings of the traditional rail transit excrement treatment method
