Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiation safety protection technology, specifically to an electron accelerator radiation safety protection system. Background Technology
[0002] In actual operation, electron accelerator irradiation chambers must ensure the stability and reliability of the accelerator to prevent personnel safety accidents caused by accelerator failure. However, an accelerator is a complex system involving multiple subsystems such as vacuum, high voltage, radio frequency, and beam transmission. Each subsystem is susceptible to failure, leading to accelerator shutdown. A key technical challenge for the irradiation chamber safety protection system is how to comprehensively monitor the shutdown of the electron accelerator during personnel inspections and issue alarms and handle faults immediately upon occurrence.
[0003] Traditional safety protection systems often employ a single shutdown method, such as a controllable emergency stop button. However, this single protective measure carries certain risks. For instance, if the single emergency stop button malfunctions or is accidentally activated and cannot be reset, the equipment may fail to stop properly, leading to a dangerous situation. In radiation protection environments, if critical equipment used for radiation shielding fails to stop operating, personnel may suffer radiation damage. Summary of the Invention

The stop button in the channel and the power button at the end of the inspection further provide operational convenience. After arriving at the accelerator room, the key components of the accelerator equipment are equipped with temperature sensors, vibration sensors and radiation sensors. These sensors are connected to the monitoring system to monitor the critical status of the accelerator, ensuring a rapid response in any abnormal situation and protecting the safety of personnel.
[0009] According to one embodiment of the present invention, it further includes: a first electric door controller for controlling the first electric door. Through the above scheme, precise control is achieved, and when personnel need to conduct inspections, the system can activate protective measures in advance to ensure that staff are free from potential radiation hazards.
[0010] According to one embodiment of the present invention, it further includes: a second electric door controller for controlling the second electric door, which can close the second electric door in a timely manner when the accelerator control fails, thereby preventing personnel from being subjected to greater radiation damage and ensuring the safety of the operators.
[0011] According to one embodiment of this utility model, the emergency stop button is connected to the emergency stop button controller, and the emergency stop button controller is electrically connected to the accelerator. Through the above scheme, the emergency stop button is set as the first line of defense, effectively ensuring the safety of personnel when carrying out inspection operations.
[0012] According to one embodiment of this utility model, the stop button is connected to the stop button controller, and the stop button controller is electrically connected to the accelerator. Through the above scheme, the stop button is set as a second safety line, which further effectively ensures the safety of personnel when carrying out inspection operations.
[0013] According to one embodiment of this utility model, the power button is connected to the power button controller, and the power button controller is electrically connected to the accelerator. Through the above scheme, the power button is set as a second safety line, which further effectively ensures the safety of personnel when carrying out inspection operations.
[0014] According to one embodiment of this utility model, the inspection channel is also equipped with an emergency lighting system, an emergency ventilation system, and an emergency broadcasting system. The emergency lighting system, emergency ventilation system, and emergency broadcasting system are electrically connected to the emergency system controller, which is electrically connected to the monitoring system. Through the above scheme, in the event of failure of the electron accelerator control, the safety of inspection personnel is ensured, sufficient lighting is provided, air circulation is maintained, and alarms or safety instructions are promptly issued through the broadcasting system, effectively solving the dangerous problems faced by personnel during inspections in traditional technologies.
[0015] The technical advantages of this application are as follows:
[0016] This application provides an electron accelerator irradiation safety protection system. An initial safety barrier is established by setting up an irradiation shield. Upon entering, inspection personnel must press the emergency stop, stop, and power buttons in a specific sequence to ensure the accelerator completely stops operating before entering the accelerator room, which contains various sensors for monitoring. This ensures the safety of inspection personnel. The monitoring center's system can collect and process sensor data in real time, enabling more comprehensive safety monitoring through data storage and analysis.

[0022] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.
[0023] Example 1
[0024] See attached document Figure 1 This utility model provides an electron accelerator irradiation safety protection system, including: an irradiation shield 1, which includes: an accelerator chamber 11 for housing an accelerator 12, and a monitoring center 3 isolated from the accelerator chamber 11 by an inspection channel 5; the inspection channel 5 forms a U-shaped channel around the accelerator chamber 11; the inspection channel 5 is connected to the monitoring center 3 by a first electric door 4, and the accelerator chamber 11 is connected to the inspection channel 5 by a second electric door 10. The first electric door 4 and the second electric door 10 are located at opposite ends of the inspection channel 5, respectively. The first electric door 4 is controlled by a first electric door controller 401, and the second electric door 10 is controlled by a second electric door 1001. Through the above scheme, direct contact between the radiation area and the outside world is effectively isolated, ensuring the safety of operators, while also ensuring a clear and orderly process for entering the accelerator chamber 11 from the outside, thus improving the safety and efficiency of the work.
[0025] See attached document Figures 2-3The aforementioned electron accelerator irradiation safety protection system also includes: a safety system, which includes: an infrared sensor 6 and an emergency stop button 7 installed on the wall at the entrance of the inspection channel 5; a stop button 8 and a power button 9 installed inside the inspection channel 5; a monitoring system 301 installed in the monitoring center 3, which includes: at least one data processing unit 302, at least one data storage unit 303, at least one data analysis unit 304 and at least one data transmission unit 305; and a temperature sensor 13, a vibration sensor 14, and a radiation sensor 15 installed on the accelerator 12, which are electrically connected to the monitoring system 301.
[0026] Through the above scheme, personnel need to go through a series of verifications and safety prompts before entering the critical area. The infrared sensor 6 and emergency stop button 7 in the inspection channel 5 can monitor the safety status of personnel in real time and stop the machine in an emergency. The stop button 8 in the channel and the power button 9 at the end of the inspection further provide operational convenience. After arriving at the accelerator 12 chamber 11, the key components of the accelerator 12 equipment are equipped with temperature sensor 13, vibration sensor 14 and radiation sensor 15. These sensors are connected to the monitoring system 301 to monitor the critical status of the accelerator 12, ensuring a rapid response in any abnormal situation and protecting the safety of personnel.
[0027] The emergency stop button 7 is electrically connected to the emergency stop button controller 701, the stop button 8 is electrically connected to the stop button controller 801, and the power button 9 is electrically connected to the power button controller 901. The emergency stop button controller 701, the stop button controller 801, and the power button controller 901 are all electrically connected to the accelerator 12. Through the above scheme, three safety lines of defense are set up with the emergency stop button 7, the stop button 8, and the power button 9, which further and effectively ensures the safety of personnel when carrying out inspection operations.
[0028] After entering inspection channel 5, inspection personnel must press the emergency stop button 7, stop button 8, and power button 9 in sequence to completely stop the accelerator chamber 11 and activate the safety protection system. If the inspection is complete, the power to the accelerator chamber 11 must be turned on by pressing the emergency stop button 7, stop button 8, and power button 9 in sequence. Pressing only one or two buttons will not start the accelerator chamber 11. This process ensures that the accelerator chamber 11 completely stops operating and activates the safety protection system, effectively preventing safety hazards caused by accelerator 12 control failure. After the inspection is completed, the same steps are repeated to turn on the power to the accelerator chamber 11, ensuring that the accelerator chamber 11 can only resume operation if all steps are correctly executed. This eliminates the possibility of starting the accelerator chamber 11 by pressing only one or two buttons, greatly improving the safety of personnel during inspections.
[0029] The aforementioned inspection channel 5 is also equipped with an emergency lighting system 501, an emergency ventilation system 502, and an emergency broadcasting system 503. The emergency lighting system 501, emergency ventilation system 502, and emergency broadcasting system 503 are electrically connected to the emergency system controller 504, which is electrically connected to the monitoring system 301. Through the above scheme, in the event of a failure of the accelerator 12 control, the safety of inspection personnel is ensured, sufficient lighting is provided, air circulation is maintained, and alarms or safety instructions are promptly issued through emergency broadcasting, effectively solving the dangerous problems faced by personnel during inspections in traditional technologies.
[0030] Working principle:
[0031] After entering the irradiation protection body 1 through the entrance door 2, the inspection personnel enter the inspection channel 5 through the first electric door 4. They need to press the emergency stop button 7, the stop button 8, and the power button 9 at the entrance of the inspection channel 5 in sequence to ensure that the accelerator 12 is completely stopped and the safety mode of the protection system is activated. After the inspection is completed, the three buttons need to be operated again in reverse order to restart the accelerator 12. Various safety devices, such as infrared sensors 6, are installed in the safety system to ensure a rapid response to any abnormalities during inspections. Meanwhile, temperature sensors 13, vibration sensors 14, and radiation sensors 15 installed in the accelerator chamber 11 monitor the status of key components of the accelerator 12 in real time via wireless sensor nodes 16 and the network, and transmit the data to the monitoring system 301 for processing and analysis. The monitoring system 301 in the monitoring center 3 organizes, stores, and analyzes the data. The inspection passage 5 is also equipped with an emergency lighting system 501, an emergency ventilation system 502, and an emergency broadcast system 503 to ensure emergency response in case of emergencies, thereby protecting the safety of the accelerator 12 and personnel. The safety control of the entire system is uniformly allocated and managed by the monitoring system 301, achieving efficient and safe protection.
