When the interval time T3 is up, the equipment program repeats the above soaking operation. During the opening and closing process of a single radiation protection shielding door, the surface of the door body is cleaned daily. There is no need for manual cleaning by staff. The cleaning block 37 is kept moist by spraying cleaning liquid at intervals to improve the cleaning effect. The wiper strip 33 can scrape off the water stains remaining on the surface of the shielding door and flow it down into the recovery water tank 32 for centralized collection. The staff only needs to replace the cleaning block 34 regularly. When it is necessary to clean the double-leaf door, the device program first controls the electric valve 37 to open for a time period of T2. At this time, the door cleaning liquid in the cleaning water tank 35 flows out from a plurality of liquid outlet holes 36 to the cleaning block 34 to wet it. When T2 is up, the device program controls the electric valve 37 to close. Then, the device program controls the third motor 311 to start forward rotation. The moving distance of the mobile cleaning seat 31 is adjusted to N2. The mobile cleaning seat 31 moves back and forth and cleans the surfaces of the two groups of radiation protection shielding doors during the movement. During the cleaning process, the wiper strip 33 can scrape off the water stains remaining on the surfaces of the shielding doors and flow them downward into the recovery water tank 32 for centralized collection. When the mobile cleaning seat 31 moves to the first infrared sensor 12, the device program controls the third motor 311 to stop and sends a stop signal to the staff. The staff manually replaces the wet cleaning block 34. Then, the device program controls the third motor 311 to start reverse rotation to wipe off the water stains remaining on the surfaces of the two groups of radiation protection shielding doors. By coordinating the use of the mobile cleaning seat 31, the electric valve 37 and the equipment program, the cleaning method can be changed according to the number of radiation protection shielding door leaves. When using a single-leaf radiation protection shielding door, the mobile cleaning seat 31 is fixed, and the surface of the door body is cleaned daily during the opening and closing of the single-leaf radiation protection shielding door. The cleaning block 37 is kept moist by spraying cleaning liquid at intervals to improve the cleaning effect and avoid the dry cleaning block 37 from wearing the door body surface. When using a double-leaf radiation protection shielding door, a mobile cleaning operation is performed and the injection amount of cleaning liquid is increased to perform a single cleaning operation. While ensuring the cleanliness of the radiation protection shielding door, the consumption of cleaning liquid can be reduced, thereby reducing the cost of daily cleaning.
