[0038] The protective door mounting frame 1 is powered by an external power source to drive the internal components.

[0039] The protective door mounting frame 1 is also equipped with an equipment program, which can control the start and stop of three sets of motors and the opening and closing of electric valve 37;

[0040] All three sets of motors, electric valves 37, and two sets of infrared sensors are connected to the equipment's program signals.

[0041] Radiation protection procedures:

[0042] When workers need to perform production operations, they first turn on the indoor power. At this time, the protective door mounting frame 1 starts, and the equipment program starts. Workers select different protective doors according to the size of the entrance and exit of the operating room for shielding operation 2. The equipment program sets the movement value of the first radiation protection shielding door 21 to M1, M2, and M3, where M1 is the minimum value and M3 is the maximum value, which can be adjusted according to specific needs. The speed of the first motor 211 is V1 and V2, where V1 is the minimum value and V2 is the maximum value, which can also be adjusted according to specific needs. When the size of the entrance and exit of the operating room is small, workers select a single door for protection operation through the equipment program control. The equipment program controls the first motor 211 to start rotating forward, and the speed is adjusted to V1. The forward movement value of the first radiation protection shielding door 21 is M2. The first motor 211 drives the first moving pulley 212. The second moving pulley 213 rotates, the first moving pulley 212 moves along the built-in moving track of the protective door mounting frame 1, and the second moving pulley 213 moves along the second moving slide rail 14. The two sets of moving pulleys can fix the moving first radiation protection shielding door 21 horizontally and vertically respectively to prevent it from shaking during the movement and causing wear on the door body. When the moving distance of the first radiation protection shielding door 21 reaches M2, the equipment program detects the signal value of the second infrared sensor 13 to ensure that the first radiation protection shielding door 21 moves to the designated position. Then the equipment program controls the first motor 211 to stop. If the equipment program does not detect the signal value of the second infrared sensor 13, the equipment program determines that the second infrared sensor 13 is faulty or damaged and sends the error information to the staff. Then the equipment program controls the first motor 211 to stop.

[0043] When the entrance and exit dimensions of the operating room are large, the staff uses the equipment program to control the selection of a double-leaf door for protective operation. The equipment program controls the first motor 211 to start in reverse, adjusting the speed to V2. The reverse movement value of the first radiation protection shielding door 21 is M1. The first motor 211 drives the first moving pulley 212 and the second moving pulley 213 to rotate. The first moving pulley 212 moves along the built-in moving track of the protective door mounting frame 1, and the second moving pulley 213 moves along the second moving slide rail 14. The two sets of moving pulleys can respectively fix the moving first radiation protection shielding door 21 laterally and longitudinally, preventing it from shaking during movement and causing damage to the door body. Wear occurs. When the first radiation shielding door 21 moves a distance of M1, it is located on one side of the second radiation shielding door 22. Then, the equipment program controls the second motor 23 to start and run in the forward direction. The rotating teeth of the second motor 23 mesh with the moving rack 24 and drive the first connecting rod 26 to move. The first connecting rod 26 drives the second connecting rod 27 to move. The second rotating shaft 272 also rotates and drives the locking block 29 to perform a locking and fixing operation. After rotation, the locking block 29 is engaged in the locking hole 224. At this time, the second radiation shielding door 22 and the first radiation shielding door 21 are tightly fitted together to complete the double door. During the locking operation, the protective gasket 225 seals the gap between the two sets of radiation protection shielding doors, achieving a shielding effect and preventing wear between the two sets of radiation protection shielding doors, thus extending the service life of the doors. After the double-door locking operation is completed, the equipment program controls the first motor 211 to rotate forward, adjusting the speed to V2. The forward movement value of the first radiation protection shielding door 21 is M3. The first motor 211 drives the first moving pulley 212 and the second moving pulley 213 to rotate. The first moving pulley 212 moves along the built-in moving track of the protective door mounting frame 1, and the second moving pulley 213 moves along the second moving slide rail 14. The wheels can fix the moving first radiation protection shielding door 21 horizontally and vertically respectively to prevent it from shaking during movement and causing wear on the door body. When the first radiation protection shielding door 21 moves a distance of M3, the equipment program detects the signal value of the first infrared sensor 12 to ensure that the two sets of radiation protection shielding doors move to the designated position. Then the equipment program controls the first motor 211 to stop. If the equipment program does not detect the signal value of the first infrared sensor 12, the equipment program determines that the first infrared sensor 12 is faulty or damaged and sends the error information to the staff. Then the equipment program controls the first motor 211 to stop.

[0044] By using two sets of radiation protection shielding doors in conjunction with the first motor 211, single or double doors can be selected for radiation protection shielding operations depending on the size of the entrance and exit of the operating room. This makes the system more versatile, allows for quick switching between single and double doors, and is convenient and less complicated to operate. The protective gasket 225 improves the sealing of the two sets of radiation protection shielding doors and prevents wear between them, thus extending the service life of the doors. The two sets of infrared sensors, in conjunction with the equipment program, can reconfirm the movement position of the two sets of radiation protection shielding doors, preventing them from moving out of position and affecting the radiation protection effect. The second motor 23, the moving rack 24, the locking block 29, and the equipment program work together to quickly lock and fix the two sets of radiation protection shielding doors, reducing installation time and eliminating the need for manual installation by staff, thus reducing their workload.

[0045] Door self-cleaning operation:

[0046] During the above operations, the equipment program controls the door self-cleaning operation. The equipment program sets the moving distance of the movable cleaning seat 31 to N1 and N2, where N1 is the minimum and N2 is the maximum, and can be adjusted according to specific needs. The opening time of the electric valve 37 is T1 and T2, and the interval time is T3, where T1 is the minimum and T3 is the maximum, and can be adjusted according to specific needs. When a single door cleaning operation is required, the equipment program controls the third motor 311 to start, and the moving distance of the movable cleaning seat 31 is adjusted to N1. At this time, the movable cleaning seat 31 moves to the middle position of the protective door mounting frame 1 and stops. Then, the equipment program controls the electric valve 37 to open, with the start time being T1. At this time, the door cleaning fluid in the cleaning water tank 35 flows out from several sets of liquid outlets 36 to the cleaning block 34 to wet it. When time T1 is up, the equipment program controls the electric valve 37 to close and performs an interval cleaning timer operation. The interval time is T3. When the interval time T3 is up, the equipment program repeats the above wetting operation. During the opening and closing of a single radiation protection shielding door, the surface of the door is cleaned daily without the need for manual cleaning by staff. The cleaning block 37 is kept moist by the intermittent spraying of cleaning fluid to improve the cleaning effect. The squeegee 33 can scrape off the water stains remaining on the surface of the shielding door and let them flow down into the recycling water tank 32 for centralized collection. Staff only need to replace the cleaning block 34 periodically.

[0047] When cleaning of the double doors is required, the equipment program first controls the electric valve 37 to open for a time of T2. At this time, the door cleaning fluid in the cleaning water tank 35 flows out from several sets of outlet holes 36 to the cleaning block 34 to wet it. When T2 is up, the equipment program controls the electric valve 37 to close. Then, the equipment program controls the third motor 311 to start rotating forward. The moving distance of the moving cleaning seat 31 is adjusted to N2. The moving cleaning seat 31 moves back and forth and cleans the surfaces of the two sets of radiation protection shielding doors during the movement. During the cleaning process, the squeegee 33 can scrape off the water stains remaining on the surface of the shielding door and let them flow down into the recycling water tank 32 for centralized collection. When the moving cleaning seat 31 moves to the first infrared sensor 12, the equipment 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 equipment program controls the third motor 311 to start rotating in reverse and wipe off the water stains remaining on the surfaces of the two sets of radiation protection shielding doors.

[0048] By using the movable cleaning seat 31, electric valve 37, and equipment program in conjunction with the system, the cleaning method can be changed according to the number of radiation protection shielding door panels. When using a single radiation protection shielding door, the movable cleaning seat 31 is fixed, and the door surface is cleaned routinely during the opening and closing of the single radiation protection shielding door. The cleaning solution is sprayed intermittently to keep the cleaning block 37 moist, improving the cleaning effect and preventing the dry cleaning block 37 from damaging the door surface. When using a double radiation protection shielding door, a movable cleaning operation is performed to increase the amount of cleaning solution injected for a single cleaning operation. This ensures the cleanliness of the radiation protection shielding door while reducing the consumption of cleaning solution and reducing the cost of daily cleaning.
