The two sensors of each pair are symmetrically arranged on both sides of the train track, and a pair of photoelectric sensors 3 are respectively arranged at the entrance and exit of the train, and a pair of photoelectric sensors 3 are respectively arranged at the front and rear end of the train. The car washing system controls the car washing according to the shielding and light transmission of the photoelectric sensors 3. The 4 pairs of photoelectric sensors 3 can be used to control the start and stop of the washing equipment, including controlling the start (detection and control of the first pair of photoelectric switches) and the end (detection and control of the fourth pair of photoelectric switches), controlling the front washing (detection and control of the second pair of photoelectric switches and the third pair of photoelectric switches) and the rear washing (detection and control of the second pair of photoelectric switches and the third pair of photoelectric switches) parking spaces. The automatic car washing starts when the front of the car enters the warehouse, and the automatic car washing ends when the rear of the car leaves the warehouse. During the car washing process, the car washing system starts in sequence or stops in sequence after washing according to the shielding and light transmission of the photoelectric sensors 3, which can save water and energy. The photoelectric sensor 3 at the end washing position controls the train to stop at the end washing position and determines whether the train stops accurately. When the front washing stop indicator light changes from red to green, the train enters the end washing area, the second pair of photoelectric switches 3 are blocked by the train head, and the third pair of photoelectric switches 3 are connected as usual. The train head stops between the second pair of photoelectric switches 3 and the third pair of photoelectric switches 3. After confirming that the train position is correct, the end brush 616 changes from a non-working state to a working state (the rotating frame 65 is driven by the rotating drive motor 68 to allow the end washing brush group to brush the end face of the train). The end brush 616 rotates, and the water spray device sprays washing liquid at the same time, and the walking mechanism starts to move. When the end brush 616 moves to the front end of the train, the lifting mechanism also starts to work to drive the uniformly rotating end brush 616 to rise, and the walking mechanism performs a variable speed movement. The two combine to form a brushing movement of the train end face shape, and the end brush 616 is washed up and down twice. The second time is brushed with circulating water. After the cleaning of the locomotive head is completed, the end brush 616 is lifted away from the locomotive head and returns to the non-working state under the action of the slewing mechanism (the rotating frame 65 is retracted under the drive of the rotating drive motor 68).

[0047] Furthermore, the water supply system of the pre-wet washing liquid spray pipe 4 includes a water supply pump group 9, a detergent metering pump group 10 and a water supply pipeline.

The air supply system is arranged in the auxiliary room 22 next to the washing garage 21, and is composed of an air compressor 16, an air tank 17 and an air supply pipeline. The compressed air generated by the air compressor 16 is input into the air tank 17 through the air supply pipeline to provide power for the pneumatic motor to realize the swinging out and retracting of the brush group.

[0050] Furthermore, it also includes a water circulation treatment system for treating waste water after washing, which can treat the waste water after washing for recycling. The water circulation treatment system consists of a water treatment and regulation device 11, an inclined tube sedimentation device 12, a photocatalytic oxidation device 13 and a submersible pump group 15. The water treatment and regulation device 11 is used to collect the waste water after washing, and let the waste water flow between different regulating tanks of the water treatment and regulation device 11 through the submersible pump group 15, and then pumped into the inclined tube sedimentation device 12 for treatment through the submersible pump group 15, and the treated water enters the photocatalytic oxidation device 13. The water circulation treatment system is set in an auxiliary room 22 next to the car wash garage 21. After being collected, the car wash wastewater first enters the water treatment and regulation equipment 11, flows between different regulating tanks through the submersible pump group 15, and after large particle impurity precipitation, pH adjustment and flocculation reaction, is pumped into the inclined tube sedimentation equipment 12 through the submersible pump group 15. The flocculated dirt sinks to the bottom of the sedimentation tank under the action of gravity and the inclined tube, and is separated from the water. The treated water enters the photocatalytic oxidation device 13, and photocatalytic oxidation is carried out to effectively remove organic impurities such as surfactants and oil stains, and effectively kill various pathogens, meeting the standards of recycled water; the effluent enters the recycled water pool for car washing.
