The water supply system is easy to overflow, leak, submerge and other accidents under the conditions of unattended operation, blocked pipeline, equipment failure and the like.
Therefore, the technique has disadvantages in that:
1. the water supply system of the mop pool is in a non-electric state, and if the water faucet is in an open state, the water faucet can continuously supply water to cause accidents of overflow, leakage, flooding and the like.
2. The motor train unit is in an electric state, and under the unattended condition, if the water faucet is in an open state, water is drained continuously.

4. The mop pool water supply system is in an electric state, the waste water tank is full, water supply to the faucet is not controlled, and the pressure at the joint of the mop pool and the waste water tank is increased due to the fact that water is full, so that leakage accidents are caused.
The state of the water faucet can not be controlled in the processes of vehicle production, returning and operation, as long as the water purifying tank has water, the water faucet is in an open state, the mop pool can continuously supply water, and accidents such as overflow, leakage, submergence and the like can occur under the conditions of unattended operation, pipeline blockage, equipment failure and the like.
For example, in a certain train, before leaving a factory in winter, a pipeline drains water, a water faucet is in an open state, after reaching a train section, a section organization is in a non-electricity maintenance state, and a mop pool water supply system is in a non-electricity state. And when the state of the tap is not confirmed, the purified water tank supplies water, the tap continuously supplies water, and the electroless overhauling waste water tank fails to drain water in time, so that the water is continuously supplied after the waste water is full, and finally, a large amount of purified water overflows into the compartment after the mop pool is full. And the joint of the waste water tank and the mop pool is leaked due to the water pressure after the waste water tank and the mop pool are full. Thereby causing flooding, leakage and flooding accidents of the motor train unit.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
