An annular filter screen is mounted on the bottom surface of the baffle ring plate, and a scale collection screen is mounted on the bottom surface of the annular filter screen. A discrete plate is rotatably mounted on the inner top surface of the receiving box within the annular filter screen. A discrete drive component connected to the discrete plate is mounted on the inner top surface of the receiving box to the right of the cleaning return pipe. An annular pipe is mounted on the inner top surface of the receiving box outside the discrete drive component. A plurality of drainage pipes are connected to the bottom surface of the annular pipe inside the discrete plate. A guide pipe is also included, with one end connected to the top surface of the annular pipe and the other end connected to the cleaning return pipe.

[0012] Furthermore, a connecting ring plate is provided on the top surface of the baffle ring plate, and the connecting ring plate is connected to the inner top surface of the receiving box by several bolts; the annular tube is connected to the inner top surface of the receiving box by several connecting seats.

[0013] Furthermore, the discrete drive component includes a rotary motor, which is disposed on the inner top surface of the receiving box and located to the right of the cleaning return pipe. The rotary motor is connected to the inner top surface of the receiving box through a placement box, and the rotating end of the rotary motor is connected to the discrete plate.

[0019] Furthermore, the heating wire is an iron-chromium-aluminum heating wire, an electric furnace wire, or a graphene heating wire.

[0020] Therefore, this utility model provides the following effects and / or advantages:

[0021] 1) The mobile trolley is used to move the cleaning device to a predetermined position when the electric water heater of the EMU needs to be cleaned. The feeding mechanism is used to allow the cleaning solution to enter the container when the mobile trolley moves the cleaning device to the predetermined position. The cleaning solution is a mixture of cleaning agent and water. The cleaning agent is food-grade citric acid or other.

[0022] The cleaning inlet pipe is used to connect with the drain pipe of the electric water heater of the EMU after the cleaning solution enters the container. The cleaning return pipe is used to connect with the overflow pipe of the electric water heater of the EMU after the cleaning solution enters the container.

[0023] The cleaning pump is used to continuously output the cleaning solution in the container after the cleaning inlet pipe is connected to the drain pipe of the electric water heater of the EMU and the cleaning return pipe is connected to the overflow pipe of the electric water heater of the EMU. The cleaning solution enters the drain pipe of the electric water heater of the EMU through the cleaning inlet pipe, then passes through the water production chamber, boiling water pipe, water storage chamber and overflow pipe of the electric water heater of the EMU, and then enters the container through the cleaning return pipe. The solution circulates for a predetermined time, so that the cleaning solution reacts with the scale on the drain pipe, water production chamber, boiling water pipe and water storage chamber of the electric water heater of the EMU, causing the scale to fall off or be decomposed.

[0024] The reflux filtration mechanism is used to quickly, thoroughly and efficiently filter the cleaning solution that enters the container from the cleaning return pipe and passes through the EMU electric water heater, so as to prevent the scale that has been removed from the EMU electric water heater from re-entering the EMU electric water heater.

[0025] The discharge mechanism is used to discharge the cleaning solution from the container after the cleaning device has finished cleaning the electric water heater of the EMU.

[0026] In summary, the cleaning of the drain pipe, water production chamber, boiling water pipe, and water storage chamber of the electric water heater in the high-speed train can be completed without the need for multiple people, which reduces labor intensity and cleaning difficulty.

[0027] 2) The discrete plate is driven to rotate continuously while the cleaning pump continuously outputs the cleaning solution in the container tank, so as to centrifugally disperse the cleaning solution that has passed through the electric water heater of the EMU and comes out from several drainage pipes to the annular filter screen. The several drainage pipes divert and guide the cleaning solution from the cleaning return pipe and the annular pipe to the discrete plate, so that the annular filter screen can quickly, fully and efficiently filter the cleaning solution. The scale that has fallen off from the electric water heater of the EMU falls into the scale collection screen plate and will not accumulate and clog the annular filter screen.

[0028] 3) The descaling mechanism is used to open after the discharge mechanism discharges the cleaning solution from the container to separate the baffle ring plate from the inner top surface of the container, thereby cleaning the baffle ring plate, the annular filter screen, and the scale collection screen plate.

[0029] 4) The heating device is used to heat the cleaning solution to a predetermined temperature after the feeding mechanism allows the cleaning solution to enter the container. The heating device is not powered on until the cleaning device has finished cleaning the electric water heater of the EMU, so as to maintain the temperature of the cleaning solution in the container and thus maintain the cleaning efficiency and quality of the cleaning solution for the electric water heater of the EMU.

The cleaning solution is a mixture of cleaning agent and water. The cleaning agent is food-grade citric acid or other.

[0042] The cleaning inlet pipe 4 is used to connect with the drain pipe of the electric water heater of the EMU after the cleaning solution enters the container tank 3. The cleaning return pipe 5 is used to connect with the overflow pipe of the electric water heater of the EMU after the cleaning solution enters the container tank 3.

The cleaning solution enters the drain pipe of the electric water heater of the EMU through the cleaning inlet pipe 4, then passes through the water production chamber, boiling water pipe, water storage chamber and overflow pipe of the electric water heater of the EMU, and then enters the container tank 3 through the cleaning return pipe 5. The solution circulates for a predetermined time, so that the cleaning solution reacts with the scale on the drain pipe, water production chamber, boiling water pipe and water storage chamber of the electric water heater of the EMU, so that the scale is removed or decomposed.

The several drainage pipes 12 divert and guide the cleaning solution that comes in from the cleaning return pipe 5 and the annular pipe 11 to the discrete plate 10, so that the annular filter screen 8 can filter the cleaning solution quickly, fully and efficiently. The scale that has fallen off from the electric water heater of the EMU falls into the scale collection screen plate 9 and will not accumulate and clog the annular filter screen 8.
