[0033] The PLC central controller 10 completes self-checking when the system starts. When the battery locomotive 2 passes the photoelectric switch 7, the photoelectric switch 7 sends a high-level signal to the PLC central controller 10. After receiving the signal, the PLC central controller 10 outputs a control signal to the electric ball valve 11 and the drive motor 91. The drive motor drives the flushing pipeline to expand evenly through the automatic telescopic component 9. After the electric ball valve 11 is opened, the high-pressure water flow forms a fan-shaped water curtain.

The rack 93 drives the first flushing pipeline 3 at the entrance end of the battery locomotive 2 to move through the connecting column 93, so that the first flushing pipeline 3 is expanded or contracted along the guide track 4. The PLC central controller 10 controls the opening and closing of the electric control valve and the action of the drive motor 91 according to the signal of the photoelectric switch 7, forming a fan-shaped water curtain covering the entire section of the battery locomotive 2, which can control the movement of the first flushing pipeline 3 and evenly flush the battery locomotive 2 group.

[0041] The control principle of the control system is:

[0042] First, turn on the power supply of the flushing device in the tunnel waterproof electrical control box 14, and the PLC central controller 10 completes self-test. When the battery locomotive 2 passes the photoelectric switch 7, the photoelectric switch 7 inputs a high-level electrical signal to the PLC central controller 10. The PLC central controller 10 receives the input signal for internal program processing, and outputs a 24V voltage signal after executing the delay program to control the electric ball valve 11 to open. The PLC central controller 10 also controls the drive motor 91 to evenly expand the flushing pipeline to increase the flushing area. The high-pressure water flow inside the shield construction circulating water pipeline flows to the first flushing pipeline 3 and the second flushing pipeline 6, and is sprayed by the flushing nozzle 8 to form a fan-shaped water curtain to complete the flushing of the battery locomotive 2 group. When the battery locomotive 2 passes the photoelectric switch 7, the high-level electrical signal output is stopped, the PLC central controller 10 stops program execution, and the output stops. When the electric ball valve 11 does not receive a voltage signal, the electric valve is closed, and the flushing nozzle 8 stops spraying water to complete the flushing of the battery locomotive 2.
