Description

Technical Field

[0001] This invention belongs to the field of nuclear engineering technology, and specifically relates to a filling station that can automatically load radioactive materials. Background Technology

[0002] In nuclear industry scenarios such as nuclear facility decommissioning and nuclear fuel reprocessing, a large amount of radioactive materials, such as radioactive material ends and waste cladding, are generated. Their safe transfer and loading are key aspects of nuclear facility operation and maintenance.

[0003] Currently, these nuclear facilities generally handle radioactive materials using manually controlled robotic arms or powered arms to complete the grabbing, transfer, and loading operations from temporary storage areas to dedicated waste bins. They cannot handle continuously discharged materials for refilling, and the operation essentially still relies on human judgment and manual control. During the operation, operators need to continuously adjust the robotic arm's posture and gripping force through visual feedback. Meanwhile, with the expansion of the nuclear industry and the significant increase in the volume of radioactive materials handled, some scenarios have begun to explore the introduction of simple automated mechanisms to assist operations. Examples include the multi-hole synchronous filling mechanism used in nuclear fuel microsphere loading and the vibratory feeding system for loading radioactive particles, providing preliminary technical references for the automated handling of radioactive materials.

[0004] However, for large radioactive materials with irregular shapes and extremely high radiation doses, such as nuclear facility terminals and spent cladding, existing transfer and loading technologies, which are mainly based on manual control, have significant shortcomings in terms of safety, efficiency, reliability, and environmental adaptability, making it difficult to meet the large-scale, safe, and efficient processing requirements of the modern nuclear industry.

[0045] It is understood that each unit or module involved in the embodiments of the present invention may correspond to only one entity structure, or may be composed of multiple entity structures, or multiple units or modules may be integrated into one entity structure.

[0046] To address the shortcomings of existing technologies that rely on manually controlled robotic arms or powered arms for handling radioactive materials and waste casings in nuclear facilities, such as safety, efficiency, reliability, and environmental adaptability, this invention provides an automated radioactive material loading station. The station comprises a shell module, a lifting module, a cap removal module, a deceleration module, a through-wall power module, and a control system.

[0047] The shell module is equipped with a material inlet channel for introducing radioactive materials;

[0048] The bottom of the shell module is equipped with a material outlet flange for docking with the waste bin, so that the imported radioactive material can be loaded into the waste bin.

[0049] The lifting module is connected to the shell module, and the cap-removing module is located at the material outlet flange at the bottom of the shell module and is connected to the lifting module. The lifting module is used to drive the cap-removing module to perform actions, thereby grabbing, opening, flipping and closing the lid of the waste bin (also called the recycling bin).

[0050] The deceleration module is connected to the material inlet channel and is used to control the introduction of radioactive materials in a pre-set sequence;

[0051] The through-wall power module is installed on the wall of the hot chamber. Its output end is equipped with a rotating handle.

This is to cooperate with the cap removal module and the material outlet flange to realize the opening, loading and closing of the cap.

[0052] The control system is electrically connected to the lifting module, deceleration module, and through-wall power module, respectively. It has a preset control program to control the operation of the lifting module, deceleration module, and through-wall power module according to the control program, so as to achieve automatic loading of radioactive materials through cooperation.

[0053] The present invention relates to an automatic radioactive material loading station that, by setting up a lifting module, a cap-removing module, and a wall-penetrating power module, can automatically open, flip, and close the waste bins. By setting up a shell module and a deceleration module, it can automatically load the end of the radioactive material and the waste casing into the waste bin according to a set program, thereby improving the safety, efficiency, reliability, and environmental adaptability of radioactive material loading.

[0054] Example 1

[0055] like Figures 1-6 As shown in the figure, this embodiment discloses a filling station that can automatically load radioactive materials, including a shell module 3, a lifting module 1, a cap removal module 2, a deceleration module 4, a wall-penetrating power module 5, and a control system (not shown in the figure).

[0056] The shell module 3 is equipped with a material inlet channel for introducing radioactive materials. The bottom of the shell module 3 is equipped with a material outlet flange 36, which is used to connect to the waste container, so that the introduced radioactive materials are loaded into the waste container 6.

[0057] Specifically, the main function of the shell module 3 is to provide sufficient filling shielding space for the filling station, allowing the lifting module 1 to be operated remotely for inspection and maintenance. The shell module 3 includes a shell body 31, with a material outlet flange 36 located at the bottom of the shell body 31. The material inlet channel includes an end chute 32 and a waste packaging chute 33, both of which are located on the shell body 31 and extend into its interior. Specifically, the inlet end of the end chute 32 is fixed to the top of the shell body 31 by welding or other means, providing a vertical inlet path for the end. The waste packaging chute 33 is a sloping channel with a certain inclination angle (e.g., 35°), and its inlet end is fixed to the side of the shell body 31 by welding or other means, providing an oblique feeding path for the waste packaging. The outlet ends of both the end chute 32 and the waste packaging chute 33 are located above the material outlet flange 36, ensuring that the introduced radioactive material can accurately fall into the waste bin.

[0058] The lifting module 1 is connected to the housing module 3 and is located inside the housing module 3. The cap-removing module 2 is located at the material outlet flange 36 at the bottom of the housing module 3 (above) and is connected to the lifting module 1 by bolts or other detachable means. The lifting module 1 is used to drive the cap-removing module 2 to perform actions, thereby grabbing, opening, flipping and closing the lid of the waste bin 6.

[0059] The deceleration module 4 is connected to the waste shell channel 33 in the material inlet channel and is used to control the introduction of radioactive materials in a set order.

[0060] The through-wall power module 5 is installed on the wall of the hot chamber. Its output end is equipped with a rotating handle 59, which is located below the material outlet flange 36. The rotating handle 59 is used to drive the rotating handle 59 to rotate and drive the waste bin 6 to lift and lower, so as to cooperate with the cap removal module 2 and the material outlet flange 36 to realize the opening, loading and closing of the cap.

[0061] The control system is electrically connected to the lifting module 1, the deceleration module 4, and the through-wall power module 5 respectively. It has a preset control program to control the operation of the lifting module 1, the deceleration module 4, and the through-wall power module 5 according to the control program, so as to realize the automatic loading of radioactive materials through cooperation.

[0062] In some embodiments, the outlet end of the end chute 32 is co-centered with the material outlet flange 36 to ensure that the end falls in the middle of the waste bin 6. The outlet end of the waste packaging chute 33 is located near the edge of the waste bin 6. The waste packaging chute 33 and the end chute 32 are staggered in the longitudinal direction to prevent the end from hitting the waste packaging chute 33 when it falls.

[0063] In some embodiments, the housing module 3 further includes a guide block 34 and a guide rail 35. The guide block 34 is located at the top of the housing body 31 and is used to guide the module 1 during remote disassembly and assembly. The guide rail 35 is located at the bottom of the housing body 31 and is used to position the module 1 during remote disassembly and assembly.

[0064] In some embodiments, the lifting module 1 includes an upper cover frame 11, a lifting assembly 12, and a first cylinder 13. The upper cover frame 11 is located on top of the housing body 31 in the housing module 3, and has a structure (such as a guide hole) adapted to the guide block 34. The lifting assembly 12 is located at the bottom of the upper cover frame 11, and has a Y-shaped groove 15. A connecting rod assembly 14 is provided in the Y-shaped groove 15. The output end of the first cylinder 13 is connected to the connecting rod assembly 14, and the connecting rod assembly 14 is connected to the cap-removing module 2. The first cylinder 13 drives the connecting rod assembly 14 to move within the Y-shaped groove 15, thereby driving the cap-removing module 2 to perform actions, realizing the grabbing, opening, flipping, and closing of the lid of the waste bin 6. The lifting module 1 is the core structure of the filling station. It is driven by the first cylinder 13 to perform linear motion, which realizes the actions of grabbing, opening, flipping and closing the lid. Specifically: when the first cylinder 13 retracts, it drives the lid-removing module 2 to open the lid, and the linear motion is converted into flipping motion through the connecting rod assembly 14 to realize the lid flipping action after opening; when the first cylinder 13 extends, it drives the lid-removing module 2 to close the lid.

[0065] Specifically, the connecting rod assembly includes main connecting rods, secondary connecting rods, bearings, bearing shafts, bearing sleeves, and standard parts. One end of each of the two main connecting rods is connected to both ends of the crossbeam, and then connected to the output end of the first cylinder 13 via the crossbeam. The other end of each of the two main connecting rods is connected to the middle section of a secondary connecting rod via bearings and bearing sleeves, and can move within the Y-shaped groove 15. The upper end of the secondary connecting rod is engaged within the Y-shaped groove 15 via a bearing shaft and can move within the Y-shaped groove 15. Operating principle: The first cylinder 13 drives the crossbeam to lift, which in turn drives the main and secondary connecting rods to move upwards in a straight line along the Y-shaped groove 15 until the bearing sleeve below the secondary connecting rod rolls to the bifurcation point of the Y-shaped groove 15. Then, the main connecting rod pulls the secondary connecting rod to perform a flipping motion, thereby driving the cap-removing module to complete the cap-flipping action after opening.

[0066] In some embodiments, the top cover frame 11 is connected to the top of the housing body 31 in the housing module 3 by a C-shaped clamp 16 for easy assembly and disassembly.

[0067] In some embodiments, the cap removal module 2 includes an upper cover plate 21, a hook 23, a push rod 24, a slider 25, a connecting rod 26, a lower cover plate 27, and a pressure head 28. The upper cover plate 21 is connected to the connecting rod assembly 14, and the lower cover plate 27 is connected to the upper cover plate 21 through the pressure head 28. One end of the connecting rod 26 is connected to the pressure head 28, and the other end is connected to the slider 25. The lower cover plate 27 has several pairs of sliding grooves inside, and each sliding groove is provided with a push rod 24. The slider 25 slides in the sliding groove and is connected to one end of the push rod 24, with the push rod 24 located at one end near the edge of the lower cover plate 27. The hook 23 is located on the other end of the push rod 24.

[0068] When the lid is opened, the lifting module 1 extends the first cylinder 13 to drive the connecting rod assembly 14 to move downward along the Y-shaped groove 15 on the lifting assembly 12, thereby causing the upper cover plate 21 to press down. Then, the connecting rod 26 pushes the slider 25 and the push rod 24 to slide outward, so that the hook 23 extends and reaches the open position to hook the lid of the waste bin 6. When the open position is reached, the waste bin 6 is lifted by the through-wall power module 5, so that the lid enters the hook 23. At this time, the first cylinder 13 retracts to drive the connecting rod assembly 14 to move upward along the Y-shaped groove 15, thereby causing the upper cover plate 21 to rise. Then, the connecting rod 26 pulls the slider 25 and the push rod 24 to slide inward, so that the hook 23 retracts to the zero position and hooks the edge of the lid, thus achieving the gripping. Continue to retract to open the lid, and continue to retract to flip the lid (such as flipping it to a vertical position).

[0069] When the lid is closed, the lifting module 1 extends the first cylinder 13 to drive the connecting rod assembly 14 to move downward along the Y-shaped groove 15 on the lifting assembly 12, so that the lid flips back to its initial state (such as a horizontal state), and continues to move downward to the lowest point. At the same time, it drives the upper cover plate 21 to press down, and then pushes the slider 25 and push rod 24 outward through the connecting rod 26, so that the hook 23 extends and reaches the open position, so that the lid is pressed tightly on the waste bin 6, thus closing the lid. At this time, the waste bin 6 is lowered as a whole by the through-wall power module 5, so that it can be separated from the filling station.

[0070] In some embodiments, the cap removal module 2 further includes a guide shaft 22 and a spring 29. The bottom end of the guide shaft 22 is connected to the lower cover plate 27, and its top end is movably mounted on the upper cover plate 21. The spring 29 is mounted on the guide shaft 22, and the two ends of the spring 29 are connected to the upper cover plate 21 and the lower cover plate 27, respectively. When the connecting rod assembly 14 moves downward and drives the upper cover plate 21 to press down, the spring 29 is compressed; when the connecting rod assembly 14 moves upward, the spring 29 provides a certain pulling force, which causes the slider 25 and the push rod 24 to slide inward through the connecting rod 26, causing the hook 23 to retract.

[0071] In some embodiments, the deceleration module 4 includes a second cylinder 41, an extension shaft 42, and a baffle 43. The second cylinder 41 is mounted on the upper cover frame 11. One end of the extension shaft 42 is connected to the output end of the second cylinder 41, and the other end of the extension shaft 42 is connected to the baffle 43. The waste packaging chute 33 is provided with a baffle inlet / outlet hole. The baffle 43 can be extended into the waste packaging chute 33 through the baffle inlet / outlet hole under the drive of the second cylinder 41. The position of the baffle 43 in the waste packaging chute 33 can be controlled by the extension and retraction of the second cylinder 41, thereby controlling the opening and closing of the waste packaging chute 33.

[0072] When the second cylinder 41 extends, the extended shaft 42 drives the baffle 43 to move downwards, passing through the baffle inlet and outlet and entering the waste packaging chute 33 to intercept and block it, thereby preventing the waste packaging from falling into the waste bin 6.

[0073] When the second cylinder 41 retracts, the extended shaft 42 drives the baffle 43 to move upward and pass through the waste shell chute 33 from the baffle inlet and outlet, so that the waste shell chute 33 is connected, and the waste shell can fall into the waste bin 6.

[0074] In some embodiments, the second cylinder 41 is provided with a lifting lug 44 for easy disassembly and assembly.

[0075] In some embodiments, the through-wall power module 5 includes a drive mechanism 51, a pre-embedded pipe 52, a through-wall pipe 53, and a through-wall assembly, the through-wall assembly including a main shaft 54, a clutch, and a drive shaft 56.

[0076] Specifically, the drive mechanism 51 is located outside the heat chamber and includes a motor and a reducer, with the motor connected to the reducer. A pre-embedded pipe 52 is installed inside the wall of the heat chamber, and a through-wall pipe 53 is installed inside the pre-embedded pipe 52. The main shaft 54 ​​is installed inside the through-wall pipe 53 via a bearing 58. One end of the main shaft 54 ​​is connected to the reducer in the drive mechanism 51 via a coupling, and the other end is connected to the transmission shaft 56 via a clutch for easy disassembly. The motor and reducer drive the main shaft 54 ​​to rotate, transmitting torque from outside the heat chamber to the transmission shaft 56 inside, thus rotating the transmission shaft 56. A rotating handle 59 is mounted on the transmission shaft 56 via welding or other methods. The waste bin 6 is located within the rotating handle 59, which rotates with the transmission shaft 56, lifting and lowering the waste bin 6.

[0077] More specifically, the coupling includes a first coupling 551 and a second coupling 552. The first coupling 551 is mounted on the reducer. One end of the main shaft 54 ​​is connected to the first coupling 551 via the second coupling 552. The clutch includes a first clutch 571 and a second clutch 572. The first clutch 571 is mounted on the other end of the main shaft 54. The drive shaft 56 is mounted in a bearing seat on the housing body 31 of the housing module 3 and is connected to the first clutch 571 via the second clutch 572. During inspection and maintenance, the entire through-assembly and the through-wall pipe 53 are pulled out from the pre-embedded pipe 52 by disengaging the first clutch 571 and the second clutch 572 for inspection and maintenance.

[0078] In some implementations, there are several sets of through-wall power modules 5, each set symmetrically arranged. For example, there may be one set of two through-wall power modules 5, each drive shaft 56 equipped with two rotating handles 59, for a total of four rotating handles 59. Two rotating handles 59 are arranged on one side, and the four rotating handles 59 are arranged diagonally to ensure even force distribution. The drive shafts 56 are driven to rotate by a motor and a reducer. After adjustment, the two drive shafts 56 achieve synchronous clockwise and counterclockwise movement, thereby driving the waste bin 6 to continue to rise and fall.

[0079] In some implementations, the control program in the control system is configured so that the end cap and waste packaging fall into the waste bin alternately, rather than falling into the waste bin together.

[0080] Specifically, according to the program settings of the upstream equipment, when the end is to be loaded, the control system controls the second cylinder 41 to extend according to the control program, thereby extending the baffle 43 into the waste packaging chute 33 to intercept and prevent the waste packaging from falling into the waste bin 6. When the waste packaging is to be loaded, the control system controls the second cylinder 41 to retract according to the control program, thereby removing the baffle 43 from the waste packaging chute 33.

[0081] The automatic radioactive material loading station of this embodiment has the following beneficial effects:

[0082] (1) Significantly improved safety: Through the cooperation of various modules, the entire process can be automated, without the need for personnel to approach the radiation environment for debugging or intervention, thus completely avoiding the risk of radiation exposure caused by manual operation; at the same time, the opening, closing and sealing actions are automatically completed to avoid the radiation leakage hazards caused by material falling or container collision.

[0083] (2) Significantly improved work efficiency: The time-consuming steps such as manual positioning and parameter adjustment are eliminated. The material is loaded alternately, the waste bin is automatically lifted and lowered and the cover is coordinated through the preset program, shortening the single operation cycle; it can be adapted to both end head and waste shell materials without the need for model change and debugging, meeting the needs of large-scale processing.

[0084] (3) Enhanced operational reliability: Through the structural optimization and precise layout of the material inlet channel and the orderly material control of the deceleration module, the material is prevented from falling out of place or colliding with each other; the mechanical transmission structure of the cap-removing module, combined with the cylinder drive, ensures that the cap grabbing, flipping and sealing actions are precise and stable, reducing problems such as container breakage and poor sealing caused by human error.

[0085] (4) Environmental adaptability and compatibility optimization: The shell module provides shielding space, and the through-wall power module adopts radiation resistance design to adapt to the high radiation environment of the hot chamber; the end (vertical feeding) and waste shell (oblique feeding) can be compatiblely loaded without changing the clamps, improving the equipment's adaptability to materials of different shapes.
