To ensure the proper functioning and extended service life of the toilet collection system, regular maintenance and servicing are required.

[0003] At present, during the operation of EMUs, toilets are in a state of high frequency use, and scale is easily formed on the inner wall of the feces collection system pipes. As the use time increases, the thickness of the scale continues to increase, and the inner diameter of the pipes decreases. The feces collection system is prone to clogging the pipes when discharging sewage, and the scale adheres to the valve body of the sewage valve, which is easy to cause damage to the sewage valve. Both will cause the toilet to malfunction and become unusable. However, when the EMU is stopped at night, the operation of clearing the toilet pipes or replacing the sewage valve takes a long time, affecting the efficiency of nighttime maintenance, and toilet malfunctions in trains running on the line are prone to cause complaints from passengers.

[0004] In view of this, a maintenance trolley for the EMU excrement collection system is proposed. Utility Model Content
