Abstract

The present application relates to a high-level radioactive waste detector handling system, which is capable of providing effective radiation shielding during the entire handling process by means of a dismounting mechanism, a coiling mechanism and a storage mechanism. In particular, the shielding cylinder in the dismounting mechanism can significantly reduce the radiation exposure risk of the operator during the process of pulling out the detector, thereby improving the safety of the operation. Compared with the traditional manual operation process, the automation characteristics of the present system can greatly shorten the time required for detector replacement. The automated lifting device, clamping device and coiling device ensure an efficient operation process, thereby improving the overall work efficiency. In addition, since the present system reduces the dependence on a large number of hand tools and the need for manual operation, the long-term labor cost caused by frequent replacement of the detector can be reduced.

[0002] In nuclear power plants, high-level radioactive detectors are critical devices used to monitor radioactivity levels inside the reactor. These detectors must withstand extreme operating conditions, including high temperatures and high doses of radiation.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Figures 1 to 3 The high-radiation detector processing system 10 in some embodiments of the present invention is shown. The high-radiation detector processing system 10 is used to remove, shield and contain detectors 30 in the core pool 20, so that detectors 30 with high radiation doses can complete the required operations underwater, and greatly reduce the steps of manual close-range operation, and greatly improve the disassembly of high-radiation detectors 30.

[0051] like Figures 1 to 15 As shown, the high-frequency detector processing system 10 includes a disassembly mechanism 1, a winding mechanism 2, and a storage mechanism 3. It should be noted that the disassembly mechanism 1 is used to pull the detector out of the reactor core. The winding mechanism 2 is used to wind the disassembled detector 30. The storage mechanism 3 is used to store the wound detector 30; that is, the storage mechanism 3 is used to store the wound detector 30.

[0052] The disassembly mechanism 1 includes a shielding cylinder 11 and a lifting device 12 that is slidably disposed inside the shielding cylinder 11. The lifting device 12 is detachably connected to the detector 30. The lifting device 12 is used to pull the detector 30 out during the movement. The shielding cylinder 11 is used to shield the radiation of the detector 30.

[0053] The winding mechanism 2 includes a winding device 21 and a clamping device 22. The clamping device 22 is used to clamp the pulled-out detector 30 and transfer it to the winding device 21. The winding device 21 is used to wind the detector 30.

[0054] Understandably, once the detector 30 is successfully removed, the clamping device 22 is responsible for transferring the detector 30 onto the reeling device 21. The clamping device 22 is designed with the shape and size of the detector 30 in mind, employing flexible or rigid grippers to ensure that the detector 30 is not damaged during transfer.

[0055] The winding device 21 contains a motor-driven spool. When the detector 30 is moved onto the winding device 21, the spool begins to rotate and gradually winds the detector 30 around it. The rotational speed and winding tension of the spool can be flexibly set. Of course, the winding mechanism 2 can be configured to wind the detector using other structures or components in the prior art that can wind detectors, and is not limited to a spool.

[0056] It should be noted that in the specific operation, the lifting device 12 is lowered and connected to the detector 30. Then, the lifting device 12 rises, pulling the detector 30 out of the core pool 20, during which the shielding cylinder 11 provides radiation protection throughout. Next, the clamping device 22 intervenes, taking over the detector 30 from the lifting device 12 and accurately placing it onto the winding device 21. Finally, the winding device 21 initiates the winding process to complete the winding of the detector 30. The entire process can be carried out in an underwater environment, reducing the chance of close contact with highly radioactive materials and improving safety.

[0057] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the coiling mechanism 2 further includes a lifting device 23. The lifting device 23 includes a coiling track 231, a lifting torque output component 232, a lifting drum 233, a lifting cable 234, a lifting pulley 235, and a lifting seat 236. The coiling track 231 is disposed in the core pool 20. The lifting torque output component 232 is driven and connected to the lifting drum 233. The lifting cable 234 is wound on the lifting drum 233. After the lifting cable 234 is wound around the lifting pulley 235, it is connected to the lifting seat 236. The lifting seat 236 is slidably disposed on the coiling track 231.

[0058] The coiling device 21 is mounted on the lifting seat 236, and the clamping device 22 is connected to the coiling track 231.

[0059] Understandably, the lifting device 23 is configured to allow for precise vertical movement of the coiling device 21 and the clamping device 22 within the core pool 20, ensuring that the detector 30 can be safely handled in the optimal position. A lifting torque output element 232 (e.g., an electric motor, hydraulic motor, or pneumatic motor) in the lifting device 23 provides power to drive the lifting drum 233. When the lifting torque output element 232 is activated, it rotates the lifting drum 233 via a transmission mechanism (e.g., gear or belt drive). As the lifting drum 233 rotates, the lifting cable 234 wound around it tightens or loosens, thereby changing the height position of the lifting seat 236.

[0060] It should be noted that the lifting cable 234 passes over the lifting pulley 235 and connects to the lifting seat 236, enabling the lifting force to be effectively transmitted to the lifting seat 236. Furthermore, the guide pulley ensures the straightness and stability of the lifting cable 234. The lifting seat 236 slides up and down along the coiled track 231 located within the core pool 20, ensuring the smoothness and accuracy of the entire movement process.

[0061] Furthermore, a groove can be provided on the winding track 231, and rollers can be provided on the lifting seat 236, with the rollers slidably disposed within the groove. The grooves can be configured to be symmetrically arranged on the winding track 231, and multiple rollers can be configured, each symmetrically disposed on the lifting seat 236. Each roller is slidably disposed within two grooves. In this way, by sliding at two different positions, the sliding stability and reliability of the lifting seat 236 can be ensured, preventing problems such as jamming or instability during sliding.

[0062] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the clamping device 22 includes a clamping frame 221, a connecting rod 222, a clamping rod 223, and two jaws 224. The connecting rod 222 is connected to the clamping frame 221, and the clamping rod 223 is rotatably connected to the connecting rod 222. The two jaws 224 are spaced apart on the clamping rod 223. The two jaws 224 are used together to clamp the detector. When the clamping rod 223 rotates, it drives the detector to be transferred to the winding device 21 through the two jaws 224.

[0063] Understandably, the clamping frame 221 serves as the basic structure of the entire clamping device 22. Fixedly mounted on the reel track 231, the clamping frame 221 provides a stable support platform for other components. One end of the connecting rod 222 is connected to the clamping frame 221, and the other end is connected to the clamping rod 223. This connection allows the clamping rod 223 to rotate around the connection point, thereby enabling the gripping of the detector 30 at different positions. The clamping rod 223 is rotatably connected to the connecting rod 222, allowing the clamping rod 223 to swing freely within a certain range. This increases the operational flexibility of the clamping device 22, enabling it to adapt to different operating angles and space constraints. Each gripper 224 is equipped with appropriate surface treatment or padding material to increase friction and prevent the detector 30 from slipping. Furthermore, the shape of the gripper 224 is adapted to the shape and size of the detector 30, ensuring good matching and robustness.

[0064] It should be noted that when the removed detector 30 needs to be transferred to the reeling device 21, the clamping rod 223 is first rotated via a control system command to adjust to the optimal gripping position. Then, the two grippers 224 close, firmly grasping the detector 30. Once the detector 30 is stably gripped, the clamping rod 223 continues to rotate, driving the detector 30 along a predetermined path via the two grippers 224 until it is accurately placed on the reeling device 21.

[0065] To ensure a safe and smooth transfer process, the clamping device 22 may also include some auxiliary mechanisms, such as:

[0066] Limit switch: Used to detect the maximum rotation angle of the clamping rod 223 to prevent damage caused by excessive rotation. Pressure sensor: Installed inside the gripper 224 to monitor the pressure applied to the detector 30 and prevent damage to the detector 30 due to excessive clamping.

[0067] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the winding device 21 includes a transverse drive 211, a transverse seat 212, a winding drive 213, a winding shaft 214, and a sliding guide 215. The transverse drive 211 is disposed on the lifting seat 236 and is drivenly connected to the transverse seat 212. The transverse seat 212 is slidably disposed on the lifting seat 236. The winding drive 213 is disposed on the transverse seat 212 and is drivenly connected to the winding shaft 214. The sliding guide 215 is slidably disposed on the lifting seat 236 and is used to receive and guide the detector to wind around the winding shaft 214.

[0068] Understandably, the traverse drive 211 is used to drive the traverse seat 212 to move horizontally along the track on the lifting seat 236. The traverse drive 211 can be an electric motor, a hydraulic cylinder, or any other suitable drive device, which provides the necessary power to enable the traverse seat 212 to move smoothly within a predetermined range.

[0069] The position of the transverse shifter 212 is controlled by the transverse shift drive 211. The transverse shifter 212 not only supports the winding drive 213 and the winding shaft 214, but also provides them with a stable support platform, ensuring accuracy during the winding process.

[0070] The reel drive 213 drives the reel shaft 214 to rotate. The reel drive 213 is typically a motor, whose output torque is sufficient to overcome the resistance of the detector 30 and can rotate the reel shaft 214 at an adjustable speed.

[0071] The winding shaft 214 is driven to rotate by the winding drive 213, and the winding shaft 214 is used to wind the detector 30. The winding shaft 214 is provided with appropriate surface texture, grooves or other anti-slip structures to ensure that the detector 30 can be firmly attached to it and prevent slippage during the winding process.

[0072] The sliding guide 215 is used to receive and guide the detector 30 so that it can be smoothly wound onto the reel 214. The sliding guide 215 may be configured with an arc-shaped guide rail or other forms of guiding structure to ensure that the detector 30 accurately enters the winding path.

[0073] It should be noted that when the clamping device 22 moves the detector 30 to the winding device 21, firstly, the lateral drive 211 is activated, driving the lateral seat 212, along with the winding drive 213 and the winding shaft 214, to move laterally and adjust to the optimal winding starting position. Then, the winding drive 213 begins to rotate the winding shaft 214, preparing to receive the detector 30.

[0074] At this point, the sliding guide 215 plays a crucial role. It automatically adjusts its position based on the initial position of the detector 30 and guides one end of the detector 30 to the starting point of the winding shaft 214. As the winding shaft 214 continues to rotate, the detector 30 is gradually wound onto it, forming a tightly arranged spiral structure.

[0075] Furthermore, to ensure the safety and accuracy of the winding process, the winding device 21 may also include some auxiliary mechanisms, such as:

[0076] Position sensor: Used to monitor the position of the transverse guide 212 and the sliding guide 215 to ensure they are always in the correct working position. Tension control system: Integrated into the reel drive 213, used to adjust the speed and torque of the reel shaft 214 to maintain appropriate winding tension and prevent the detector 30 from being too loose or too tight.

[0077] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the sliding guide 215 includes a sliding base 2151, a sliding drive 2152, a first guide wheel 2153, a first guide cylinder 2154, an opening and closing drive 2155, a second guide wheel 2156, and a second guide cylinder 2157.

[0078] The sliding seat 2151 is disposed on the lifting seat 236, the sliding drive member 2152 is driven and connected to the sliding seat 2151, the first guide wheel 2153, the first guide cylinder 2154 and the opening and closing drive member 2155 are respectively disposed on the sliding seat 2151, the second guide wheel 2156 and the second guide cylinder 2157 are respectively slidably disposed on the sliding seat 2151, and the opening and closing drive member 2155 is driven and connected to the second guide wheel 2156 and the second guide cylinder 2157;

[0079] The opening and closing drive component 2155 is used to drive the second guide wheel 2156 and the second guide cylinder 2157 to move together, so that the second guide wheel 2156 and the first guide wheel 2153 move and abut against the detector from opposite sides, and the first guide cylinder 2154 and the second guide cylinder 2157 together enclose a cylindrical space with open ends, and then the detector passes through the cylindrical space between the second guide wheel 2156 and the first guide wheel 2153.

[0080] Understandably, the slide seat 2151 provides a support platform for the entire slide guide 215 and allows it to move horizontally along a predetermined track.

[0081] The sliding drive 2152 is used to drive the sliding seat 2151 to move horizontally relative to the lifting seat 236. The sliding drive 2152 can be an electric motor, a hydraulic cylinder, or any other suitable drive device, which provides the necessary power to enable the sliding guide 215 to move smoothly within a predetermined range to adjust to the optimal guiding position.

[0082] The first guide wheel 2153 and the first guide cylinder 2154 are respectively disposed on the sliding seat 2151 for initial guidance of the detector 30. The first guide wheel 2153 helps the detector 30 smoothly enter the winding guide path.

[0083] The opening / closing drive component 2155 is mounted on the sliding seat 2151 and is used to control the opening and closing actions of the second guide wheel 2156 and the second guide cylinder 2157. The opening / closing drive component 2155 can be pneumatic, electric, or other types of actuators to achieve rapid response and precise control.

[0084] The second guide wheel 2156 and the second guide cylinder 2157 are slidably disposed on the sliding seat 2151 and are driven and connected by the opening and closing drive member 2155. Their function is to move and hold the detector 30 from opposite sides. In this way, it is ensured that the detector 30 can be stably clamped and accurately inserted between the second guide wheel 2156 and the first guide wheel 2153.

[0085] It should be noted that when the clamping device 22 moves the detector 30 to the vicinity of the winding device 21, the sliding guide 215 is first adjusted to the optimal position by the sliding drive 2152. At this time, the first guide wheel 2153 and the first guide cylinder 2154 are ready to receive one end of the detector 30. Next, the opening and closing drive 2155 is activated, driving the second guide wheel 2156 and the second guide cylinder 2157 to move towards the detector 30 until they move from both sides to hold the detector 30. As the second guide wheel 2156 and the second guide cylinder 2157 further close, the first guide cylinder 2154 and the second guide cylinder 2157 together form a cylindrical space open at both ends. After the detector 30 passes through the cylindrical space, it is firmly positioned between the second guide wheel 2156 and the first guide wheel 2153. The detector can be guided from a predetermined position to the winding shaft 214 under the guidance of the second guide wheel 2156 and the first guide wheel 2153, thereby adjusting the corresponding winding position of the detector 30, so that the detector 30 can be wound more tightly under control.

[0086] Furthermore, to ensure the safety and accuracy of the guiding process, the sliding guide 215 may also include some auxiliary mechanisms, such as:

[0087] Position sensor: Used to monitor the position of the sliding seat 2151 to ensure it is always in the correct working position. Pressure sensor: Installed inside the second guide wheel 2156 and the second guide cylinder 2157 to monitor the pressure applied to the detector 30 and prevent damage to the detector 30 due to excessive clamping.

[0088] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the reeling device 21 further includes a reeling seat 216, which is disposed on the lifting seat 236, and the reeling shaft 214 is movably inserted into the reeling seat 216.

[0089] Understandably, the reel holder 216 is mounted on the lifting seat 236, serving as a support structure for the reel 214. The reel holder 216 is provided with appropriate bores or bearings, allowing the reel 214 to be movably inserted within it, ensuring both the stability of the reel 214 and allowing for smooth rotation. To accommodate reel 214s of different sizes, the reel holder 216 may be equipped with an adjustable clamping device or adopt a standard design for quick replacement and maintenance.

[0090] It should be noted that the winding holder 216 ensures that the winding shaft 214 does not generate unnecessary vibration or offset during high-speed rotation, thereby improving the accuracy and reliability of the winding process. The bearings or bushings on the winding holder 216 reduce friction, allowing the winding shaft 214 to rotate more smoothly. This is crucial for maintaining constant winding tension, especially when dealing with long and thin detectors 30.

[0091] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the high-frequency detector processing system 10 further includes a receiving mechanism 4, which includes a receiving slide rail 41, a receiving slide block 42, a receiving drive component 43, a receiving cylinder 44, and a telescopic drive component 45.

[0092] The guide rail 41 is mounted on the lifting seat 236, the guide slide 42 is slidably mounted on the guide rail 41, the guide drive 43 is driven and connected to the guide slide 42, the guide cylinder 44 is slidably mounted on the guide slide 42, and the telescopic drive 45 is driven and connected to the guide cylinder 44.

[0093] The receiving drive 43 is used to drive the receiving slide 42 to slide along the receiving slide rail 41 so that the receiving tube 44 is aligned with or offset from the winding device 21; the telescopic drive 45 is used to drive the receiving tube 44 to move towards or away from the winding device 21. One end of the receiving tube 44 is for the detector after winding to fall into, and the other end of the receiving tube 44 is for the detector to fall out into the storage mechanism 3.

[0094] Understandably, the guide rail 41 serves as the moving track for the guide slide 42, ensuring its smooth sliding along a predetermined path. The guide slide 42 is driven by the guide drive 43, thereby controlling its positional changes. The guide drive 43 drives the guide slide 42 to slide along the guide rail 41 to adjust the position of the guide tube 44, aligning it with or offsetting it from the winding device 21. The guide tube 44 receives the coiled detector 30 falling from the winding device 21 and guides it into the receiving mechanism 3. The telescopic drive 45 drives the guide tube 44 to move towards or away from the winding device 21 to facilitate the reception and transfer of the detector 30.

[0095] It should be noted that the receiving drive 43 drives the receiving slide 42 to slide along the receiving slide rail 41, aligning the receiving cylinder 44 with the winding device 21. At this time, the receiving cylinder 44 is in a state ready to receive the coiled detector 30. After the winding device 21 completes winding the detector 30, the winding shaft 214 exits the winding position to release the detector 30, allowing it to fall into one end of the receiving cylinder 44. The receiving cylinder 44 should be designed to ensure that the detector 30 can enter smoothly and prevent damage during transfer; for example, the end of the receiving cylinder 44 can be designed with a funnel-like structure to smoothly receive the coiled detector. The telescopic drive 45 drives the receiving cylinder 44 to move away from the winding device 21. This process ensures that the detector 30 can fall smoothly from the other end of the receiving cylinder 44 into the receiving mechanism 3. After the detector 30 falls into the receiving mechanism 3, the telescopic drive 45 drives the receiving cylinder 44 back to its initial position. Next, the receiving drive 43 can remove the receiving slide 42 and the receiving cylinder 44 to prepare for the processing of the next detector 30.

[0096] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the storage mechanism 3 includes several storage devices 31. Each storage device 31 includes a storage cylinder 311, a cover, and a lifting crown 313. The storage cylinder 311 is provided with an inlet end 3111. The cover is detachably placed on the inlet end 3111. The lifting crown 313 is placed on the inlet end 3111 and is used to lift the storage cylinder 311.

[0097] Understandably, the receiving cylinder 311 is used to store the already wound detector 30. The receiving cylinder 311 is provided with an inlet end 3111 to facilitate the smooth entry of the detector 30 from the receiving mechanism 4. A removable cap is provided on the inlet end 3111 of the receiving cylinder 311 to seal the receiving cylinder 311, preventing leakage of radioactive materials and avoiding any impact from the internal detector 30 on the external environment. A lifting crown 313 is used to facilitate the lifting and handling of the receiving cylinder 311. The design of the lifting crown 313 should ensure sufficient strength and stability to withstand various operating conditions.

[0098] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the high-frequency detector processing system 10 further includes a lifting mechanism 5, which includes a lifting seat 51, a lifting sleeve 52, a lifting core rod 53, a lifting pin 55, a lifting slider 56, a lifting mounting seat 59, a plurality of lifting elastic levers 57 and a plurality of lifting alignment pins 58.

[0099] One end of the lifting sleeve 52 is connected to the lifting base 51, and the other end of the lifting sleeve 52 is connected to the lifting mounting base 59. The lifting core rod 53 is slidably inserted through the lifting sleeve 52. One end of the lifting core rod 53 is provided with a release hole and a clamping hole, and the other end of the lifting core rod 53 is connected to the lifting slider 56. The lifting pin 55 is set on the lifting base 51 and can be detachably inserted into the release hole and the clamping hole. Each lifting elastic lever 57 is rotatably set on the lifting mounting base 59 and each lifting elastic lever 57 is movably supported on the lifting slider 56. Each lifting alignment pin 58 is set on the lifting mounting base 59. The lifting core rod 53 is configured to drive the lifting slider 56 to slide, so that the lifting slider 56 supports each lifting elastic lever 57 to retract or open together.

[0100] The lifting crown 313 has several lifting alignment holes 3131 and several lifting buckle holes 3132. Each lifting alignment hole 3131 is for each lifting alignment pin 58 to be inserted one-to-one, so that each lifting spring lever 57 is aligned with each lifting buckle hole 3132.

[0101] When the lifting pin 55 is inserted into the release hole, each lifting spring tab 57 disengages from the lifting buckle hole 3132; when the lifting pin 55 is inserted into the clamping hole, each lifting spring tab 57 clamps into each lifting buckle hole 3132.

[0102] Understandably, the lifting base 51 serves as the basic support platform for the entire lifting mechanism 5. The lifting sleeve 52 provides a sliding guide for the lifting core rod 53. The lifting core rod 53 slides along the lifting sleeve 52 and drives the lifting slider 56 to move. The lifting pin 55 is mounted on the lifting base 51 and is detachably inserted into the release hole 531 or clamping hole 532 on the lifting core rod 53, thereby fixing the lifting core rod 53 and the lifting sleeve 52 when they are in different relative positions, thus controlling the state of the lifting spring levers 57. The lifting slider 56 movably holds each lifting spring lever 57, causing them to retract or expand together. Each lifting spring lever 57 is movably held by the lifting slider 56 and can retract or expand at different positions to lock or release the lifting crown 313 of the storage cylinder 311. Each lifting alignment pin 58 is used to align with the lifting alignment hole 3131 on the lifting crown 313 of the storage tube 311 to ensure that the lifting mechanism 5 is correctly connected to the storage tube 311.

[0103] It should be noted that the lifting mechanism 5 is moved above the storage cylinder 311, so that the lifting alignment pin 58 is inserted into the lifting alignment hole 3131 on the lifting crown 313. At this time, the lifting spring lever 57 is in the standby state.

[0104] After the lifting mechanism 5 is correctly aligned with the storage cylinder 311, the lifting pin 55 is first inserted into the release hole of the lifting core rod 53. This step causes the lifting spring lever 57 to disengage from the lifting buckle hole 3132 on the lifting crown 313, keeping it in a loose state for easy subsequent actions.

[0105] Next, the lifting core rod 53 is driven to slide along the lifting sleeve rod 52 by an external power source (such as a hydraulic cylinder or electric motor), which in turn moves the lifting slider 56. As the lifting slider 56 moves, it will press against the lifting spring lever 57, causing it to gradually open from the retracted state, preparing to lock the lifting crown 313.

[0106] When the lifting slider 56 moves to the predetermined position, the lifting pin 55 is pulled out from the release hole and inserted into the clamping hole. At this time, the lifting spring lever 57 is fully opened under the action of the lifting slider 56 and accurately engages with the lifting buckle hole 3132 on the lifting crown 313 to achieve a firm connection.

[0107] Once the lifting spring lever 57 is securely engaged with the lifting crown 313, the lifting mechanism 5 can activate the lifting equipment to safely lift and transport the storage cylinder 311 to the designated location. The entire process should be carried out smoothly to avoid any sudden movements that could cause damage.

[0108] After placement at the target location, slide the lifting core rod 53 so that the lifting pin 55 can be inserted into the release hole 531. At this time, inserting the lifting pin 55 into the release hole 531 will release the lifting spring lever 57 and the lifting crown 313. Subsequently, the lifting mechanism 5 can be withdrawn to prepare for the next operation.

[0109] Specifically, the lifting spring lever 57 includes a movable lever 571, a torsion spring 572, and a rotating pin 573. The rotating pin 573 is disposed on the lifting mounting base 59, the torsion spring 572 is sleeved on the rotating pin 573, the movable lever 571 is rotatably disposed on the rotating pin 573, and the torsion spring 572 is drivenly connected to the movable lever 571. The torsion spring 572 provides a force to drive the movable lever 571 to move and resist the lifting slider 56. Thus, when the position of the lifting slider 56 changes, the lifting slider 56 can rotate the movable lever 571 by pressing against it, thereby allowing the movable lever 571 to be detachably locked into the lifting latch hole 3132.

[0110] like Figures 1 to 15 As shown, in some embodiments of the high-frequency detector processing system 10, the high-frequency detector processing system 10 also includes an operating platform 6. The operating platform 6 is provided with a pedestrian walkway 61. The pedestrian walkway 61 is provided with a plurality of hanging racks 62. The hanging racks 62 are provided with hanging holes 64, and the hanging holes 64 allow the lifting base 51 to be detachably installed therein.

[0111] Understandably, the pedestrian walkway 61 is used to provide a safe passage for workers. The design of the pedestrian walkway 61 should consider width and anti-slip properties to ensure the safety of pedestrians. Several hangers 62 can be configured to be installed on or around the pedestrian walkway 61 for suspending the lifting base 51 of the lifting mechanism 5. Each hanger 62 has a hanging hole 64, allowing the lifting base 51 to be easily inserted and secured. Of course, the hanging hole 64 can also be configured for hanging long pole tools for other functions or purposes. The hanging hole 64 allows the lifting base 51 to be detachably installed. The hanging hole 64 ensures that the lifting base 51 is securely suspended and facilitates quick installation and removal.

[0112] Furthermore, to ensure the security and functionality of the operating platform 6, the operating platform 6 can be further configured to have the following structures:

[0113] Safety railing 63: Safety railings are installed around the pedestrian walkway 61 to prevent workers from falling accidentally and to improve safety.

[0114] Signage system: Clear signs are installed on the pedestrian walkway 61 and the hanging rack 62 to indicate the function and precautions of each area, helping staff to quickly find the required location.

[0115] Lighting system: Install adequate lighting equipment on the operating platform to ensure safe operation even in low light conditions.

[0116] Emergency exits: Plan reasonable emergency exits to ensure that people can be evacuated quickly in an emergency.

[0117] like Figures 1 to 15 As shown, in some embodiments of the disassembly mechanism 1, the shielding cylinder 11 is cylindrical and open at both ends. Understandably, the open ends of the shielding cylinder 11 allow a power source outside the shielding cylinder 11 to be connected to the lifting device 12 via the upper open end, and also allow the lifting device 12 to be connected to the detector via the lower open end.

[0118] like Figures 1 to 15 As shown, in some embodiments of the disassembly mechanism 1, the lifting device 12 includes a lifting power device 13, which includes a lifting middle mounting platform 131, a lifting top mounting platform 132, a lifting drive component 133, a lifting shaft 134, a lifting reversing wheel 135, and a lifting cable 136.

[0119] The middle lifting platform is located between the two ends of the shielding cylinder 11, the top lifting platform 132 is located at the end of the shielding cylinder 11, the lifting drive component 133 is located on the middle lifting platform 131, the lifting drive component 133 is driven and connected to the lifting shaft 134, the lifting reversing wheel 135 is located on the top lifting platform 132, the lifting cable 136 is wound on the lifting shaft 134, and the lifting cable 136 is connected to the lifting device 12 after passing around the lifting reversing wheel 135.

[0120] Understandably, the lifting mid-mounted platform 131 serves as a support platform for the lifting drive 133 and other related components. The lifting top-mounted platform 132 supports the lifting reversing wheel 135 and provides guidance for the lifting cable 136. The lifting drive 133 provides the power required for lifting. It can be an electric motor, hydraulic motor, or other form of power source, driving the lifting shaft 134 to rotate via a transmission mechanism (such as gears or belts). The lifting shaft 134 winds the lifting cable 136. The lifting reversing wheel 135 changes the direction of the lifting cable 136, ensuring that the lifting cable 136 is correctly connected to the lifting device 12 and maintains appropriate tension during lifting. The lifting cable 136 serves to transmit power.

[0121] like Figures 1 to 15 As shown, in some embodiments of the dismantling mechanism 1, the lifting power device 13 further includes a lifting frame 137, on which two lifting shafts 138 are provided. The two lifting shafts 138 are connected to external lifting equipment to lift the entire dismantling mechanism 1.

[0122] Understandably, after the dismantling mechanism 1 is hoisted to the predetermined position by the lifting frame 137, the lifting device 12 can be raised and adjusted to the bottom of the shielding cylinder 11, and the connection between the lifting device 12 and the detector 30 can be completed accordingly. Subsequently, the lifting drive component 133 drives the lifting shaft 134 to rotate and retract the lifting cable 136, thereby the lifting cable 136 drives the lifting device 12 to move, and then the lifting device 12 drives the detector 30 to be pulled out of the reactor core, completing the dismantling of the detector 30.

[0123] It should be noted that after the detector 30 is pulled out, it is still shielded by the shielding tube 11, and the shielding tube 11 is completely submerged in water, so that the detector 30, which has high radioactivity after long-term use, can be shielded.

[0124] like Figures 1 to 15As shown, in some embodiments of the disassembly mechanism 1, the lifting device 12 includes a lifting body 121, a lifting connecting chain 122, and a lifting connecting shackle 123. The lifting body 121 is slidably disposed inside the shielding cylinder 11. One end of the lifting connecting chain 122 is connected to the bottom of the lifting body 121, and the other end of the lifting connecting chain 122 is connected to the lifting connecting shackle 123. The lifting power device 13 is connected to the top of the lifting body 121.

[0125] Understandably, the lifting power unit 13 can drive the lifting body 121 to move up and down along the shielding cylinder 11, so that the lifting body 121 drives the lifting connection shackle 123 through the lifting connection chain 122, and then drives the detector 30 to be pulled out of the reactor core through the lifting connection shackle 123.

[0126] like Figures 1 to 15 As shown, in some embodiments of the disassembly mechanism 1, the disassembly mechanism 1 further includes a disconnection device 14, which includes a disconnection connecting cylinder 141, a disconnection enclosure 142, and a disconnection connecting ring 143. The disconnection connecting ring 143 is disposed on the disconnection connecting cylinder 141, and the disconnection enclosure 142 is movably disposed on the disconnection connecting cylinder 141.

[0127] The lifting ring 143 is connected to the lifting shackle 123. During rotation, the retaining member 142 can clamp and fix the end of the detector 30 together with the connecting cylinder 141.

[0128] Understandably, when the detector needs to be disassembled, the connecting sleeve 141 and the disassembly enclosure 142 are used to jointly enclose and lock the end of the detector 30, and the disassembly connection lifting ring 143 is connected to the lifting connection shackle 123. In this way, the lifting body 121 can pull the detector 30 out of the reactor core through the disassembly connection device 14 during the movement.

[0129] Furthermore, such as Figures 1 to 15 As shown, in some embodiments, the disconnecting connection device 14 also includes a disconnecting locking screw 144, which passes through and is screwed to the disconnecting enclosure 142, and the disconnecting locking screw 144 is movably supported against the disconnecting connecting cylinder 141.

[0130] Understandably, by rotating the locking screw 144 so that it does not protrude to the other side of the pull-out enclosure 142, the locking screw 144 can be prevented from obstructing the rotation of the pull-out enclosure 142. However, by rotating the locking screw 144 so that it protrudes to the other side of the pull-out enclosure 142, the locking screw 144 abuts against the pull-out connecting cylinder 141, thus preventing the pull-out enclosure 142 from rotating relative to the pull-out connecting cylinder 141. This maintains the clamping state of the pull-out enclosure 142 and the pull-out connecting cylinder 141 on the detector.

[0131] It should be noted that, through the content of this type of embodiment, the connection between the connecting device 14 and the detector 30 can be quickly disconnected, which greatly improves work efficiency.

[0132] The implementation of this invention has the following beneficial effects:

[0133] This invention relates to a high-level radioactive detector processing system. By incorporating a disassembly mechanism, a coiling mechanism, and a storage mechanism, this system provides effective radiation shielding throughout the processing. In particular, the shielding cylinder in the disassembly mechanism significantly reduces the radiation exposure risk to workers during detector removal, thereby improving operational safety.

[0134] Compared to traditional manual operation procedures, the automation of this system significantly reduces the time required for detector replacement. Automated lifting, clamping, and reeling mechanisms ensure efficient operation, thereby improving overall work efficiency. Furthermore, because this system reduces reliance on numerous hand tools and manual operation, it lowers the long-term labor costs associated with frequent detector replacements.
