Description

Technical Field

[0001] The present invention relates to the technical field of radioactive waste treatment, in particular to a clamp for treating radioactive metal waste. Background Art

[0002] The operation and maintenance of nuclear power plants generates large amounts of radioactive metal waste, such as spent nuclear fuel rods and radioactive equipment components. Due to their radioactive properties, these wastes require specialized treatment and disposal methods to ensure personnel safety and environmental protection. However, traditional methods for handling radioactive metal waste have numerous limitations.

[0003] In terms of manual handling risks, manual handling of radioactive metal waste carries the risk of radiation exposure, posing a serious threat to the health of operators. Even if operators wear protective gear, prolonged exposure to radiation increases the risk of cancer and other radiation-related illnesses. In terms of efficiency, manual handling is inefficient, especially when handling large quantities or heavy waste, as it is labor-intensive and time-consuming. For example, moving a radioactive equipment component weighing hundreds of kilograms requires several hours of collaborative work by multiple operators, who also need to take multiple breaks to avoid excessive fatigue, significantly impacting waste disposal progress.

[0004] Operational complexity is also a major challenge. Some radioactive metal wastes are irregular in shape or large in size, making manual clamping and handling operations complex and difficult to achieve precise control. For radioactive metal fragments with odd shapes, it is difficult for humans to accurately find the right clamping points, which can easily cause the waste to fall during transportation and cause radioactive material leakage accidents. In addition, existing clamps and handling equipment are often designed for specific types of waste and lack versatility, making it difficult to adapt to radioactive metal waste of different shapes and sizes. This leads to the need to frequently change equipment when handling different types of waste, increasing equipment costs and operational difficulty.

[0005] While some devices have remote operation capabilities, their control accuracy, stability, and reliability still need to be improved. During remote operation, issues such as signal transmission delays and untimely device responses make it difficult to precisely control the clamp's movements, potentially leading to loose clamping or operational errors, and failing to meet the requirements for safe and efficient disposal of radioactive metal waste. Therefore, there is an urgent need for a radioactive metal waste disposal clamp that reduces manual operation risks, improves processing efficiency, and enhances versatility and remote operation accuracy. Summary of the Invention

[0016] Furthermore, it is preferred that the slide is arranged corresponding to the receiving sleeve, and the clamping block corresponds to the receiving space to form a clamping space for clamping the radioactive metal waste to be clamped.

[0017] Furthermore, it is preferred that the slide is an annular disc structure, the guide rail is arc-shaped, and a plurality of the clamping blocks are arranged at intervals around the center of the slide.

[0018] Furthermore, it is preferred that the clamping blocks are distributed symmetrically along the center of the slide.

[0019] Furthermore, it is preferred that the clamping block comprises a supporting portion and a clamping portion connected to the supporting portion, and the contact surface between the clamping portion and the radioactive metal waste to be clamped is a plane or an arc surface extending along the axial direction.

[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] like Figure 1-Figure 4 As shown, the present invention provides a clamp for the disposal of radioactive metal waste, including a fixed plate 10, a rotating disk 20 arranged on the fixed plate 10, a rotating drive unit 30 that drives the rotating disk 20 to rotate relative to the fixed plate 10, a receiving sleeve 40, a clamping unit 50 and an intelligent control system.

[0038] The fixing plate 10, serving as the base support for the entire fixture (541 components), is made from a high-strength, corrosion-resistant specialty alloy, such as molybdenum-containing austenitic stainless steel. This ensures long-term stability in radioactive environments, protecting against both radiation and chemical corrosion. Multiple mounting holes are located on its base, allowing for secure connection to fixtures such as mounting brackets via bolts, ensuring the fixture's stability during operation. Lifting rings can also be installed to facilitate transport and rigging of the entire fixture.

[0039] The receiving sleeve 40 is mounted on the rotating disk 20 and connected to the fixed plate 10 via a high-precision bearing to ensure smooth and stable rotation. The receiving sleeve 40 forms a receiving space for receiving the radioactive metal waste to be clamped. This receiving space can be achieved by allowing the radioactive metal waste to fall into the receiving sleeve 40 and remain there, achieving initial fixation and retention. Alternatively, the receiving sleeve 40 can be used to clamp the metal waste.

[0040] The surface of the rotating disk 20 is specially treated to form an anti-slip texture, which increases the friction between the rotating disk 20 and the receiving sleeve 40 and prevents the receiving sleeve 40 from sliding relative to each other during rotation.

[0041] The intelligent control system communicates with the clamping unit 50 and the rotary drive unit 30, respectively. The intelligent control system is the core control component of the entire clamp. Utilizing advanced industrial control computers and high-precision sensors, the intelligent control system can acquire real-time information about the type, size, and weight of radioactive metal waste. For example, laser rangefinders and weight sensors installed on the clamp can accurately measure the size and weight of the waste and transmit this data to the intelligent control system. The intelligent control system precisely controls the rotary drive unit 30 and clamping unit 50 based on pre-set programs and acquired waste parameters. When multi-angle processing of the waste is required, the intelligent control system issues instructions to the rotary drive unit 30, controlling the rotary drive 31 to rotate the rotating disk 20 at a predetermined angle and speed. During the clamping process, the intelligent control system precisely adjusts the output power of the clamping drive 51 based on the size and weight of the waste, thereby controlling the clamping force of the clamping block 54 to ensure that the waste is securely clamped without being damaged by excessive clamping force. In addition, the intelligent control system also has remote monitoring and operation functions. Operators can view the working status of the fixture in real time through the remote terminal and perform remote control, which greatly reduces the risk of manual operation and improves the safety and convenience of operation.

[0042] Working process: After the workpiece to be clamped (radioactive metal waste) is hoisted and dropped into the receiving sleeve 40, the receiving sleeve 40 is initially positioned and fixed. For special workpieces to be clamped, it is avoided to clamp to areas that cannot be clamped (there may be special areas in certain directions on the workpiece. Clamping of special areas will affect product performance and subsequent normal operation). At this time, under the precise control of the intelligent control system, the rotary drive unit 30 is driven to move, driving the rotating disk 20 to rotate, and then driving the receiving sleeve 40 to achieve multi-angle processing. Regardless of whether the waste is of regular or irregular shape, the accuracy and stability of the operation can be ensured, reducing safety accidents caused by operational errors. The clamping unit 50 is configured to clamp radioactive metal waste. The intelligent control system controls the clamping unit 50 to perform clamping action, thereby achieving stable clamping.

[0043] In one embodiment, the rotary drive unit 30 includes a rotary drive member 31, a worm 32 disposed at the output end of the rotary drive member 31, and a turbine 33 meshing with the worm 32. The turbine 33 is disposed between the fixed plate 10 and the rotating disk 20 to drive the rotating disk 20 and the receiving sleeve 40 to rotate. The rotary drive member 31 preferably utilizes a high-precision servo motor, which has the characteristics of fast response speed and high control accuracy, and can accurately adjust the rotation angle and speed according to the instructions of the intelligent control system. The worm 32 is mounted on the output shaft of the servo motor and meshes with the turbine 33. The turbine 33 is disposed between the fixed plate 10 and the rotating disk 20. When the servo motor is started, it drives the worm 32 to rotate. The worm 32 transmits power to the turbine 33 through meshing transmission with the turbine 33, thereby driving the rotating disk 20 and the receiving sleeve 40 mounted thereon to rotate synchronously. The worm 32 - turbine 33 transmission structure has good self-locking performance. When the rotating disk 20 rotates to a specified angle, it can automatically lock to prevent the rotating disk 20 from accidentally rotating due to external interference or equipment vibration, thereby ensuring the safety of radioactive metal waste during the disposal process.

[0044] In one embodiment, the receiving sleeve 40 includes a horizontally disposed stopper 41 and an axially extending sleeve 42 connected to the stopper 41. The stopper 41 engages the top surface of the rotating disk 20, while the sleeve 42 covers the inner wall of the turbine 33. The stopper 41 is disc-shaped, slightly larger in diameter than the rotating disk 20. Its bottom is provided with a groove that matches the anti-slip texture of the rotating disk 20. During installation, the groove tightly mates with the anti-slip texture of the rotating disk 20, ensuring a secure connection between the stopper 41 and the rotating disk 20 and preventing horizontal displacement of the receiving sleeve 40. The sleeve 42 covers the inner wall of the turbine 33. Its outer wall may be provided with a guide groove that interacts with a guide protrusion on the outer surface of the turbine 33, further enhancing the connection stability between the receiving sleeve 40 and the turbine 33. It also serves as a guide during rotation, ensuring smooth rotation of the receiving sleeve 40. Furthermore, the sleeve portion 42 shields and covers the inner wall of the turbine 33 to prevent impurities such as dust from entering the turbine 33 and affecting its performance.

[0045] In a preferred embodiment, the sleeve portion 42 includes a bell-shaped guide portion 421 and a receiving portion 422 connected to the guide portion 421 and extending in the axial direction. The bell-shaped design of the guide portion 421, with its optimized opening angle, can effectively guide the radioactive metal waste into the receiving sleeve 40 smoothly. Even for irregularly shaped waste, it can reduce obstacles during placement and reduce the difficulty of operation for operators. The diameter of the receiving portion 422 is smaller than the radioactive metal waste to be clamped, or the port position of the receiving portion 422 is closed. When the diameter of the receiving portion 422 is smaller than the waste, the waste is placed above the receiving portion 422 and initially positioned by its own gravity and the blocking effect of the receiving portion 422. When the port position of the receiving portion 422 is closed, an elastic material or a retractable structure can be used to achieve port closure. After the waste is placed, it can be tightly wrapped, further enhancing the stability of the receiving portion and preventing the waste from falling.

[0046] In a preferred embodiment, the clamping unit 50 includes a clamping drive 51, a slide 52 connected to the output end of the clamping drive 51, a plurality of clamping blocks 54, and a plurality of sliders 53 connected to the clamping blocks 54. The slide 52 is provided with a guide rail 521, and the slider 53 can slide relative to the slide 52 within the guide rail 521, thereby driving all the clamping blocks 54 to perform a clamping action or a release action. The clamping drive 51 can also be a high-precision servo motor, or a cylinder that can accurately control the movement of the slide 52, thereby achieving precise adjustment of the clamping force of the clamping blocks 54. The slide 52 is arranged corresponding to the receiving sleeve 40 and is an annular disc structure. Its diameter matches the outer diameter of the receiving sleeve 40, ensuring that the slide 52 can completely cover the top opening of the receiving sleeve 40 so as to clamp the radioactive metal waste placed in the receiving sleeve 40. The surface of the slide 52 is provided with a curved guide rail 521. The curvature of the guide rail 521 matches the circumference of the slide 52. One end of the guide rail 521 extends from the outer edge of the slide 52 to the center of the slide 52, with the protrusion of the guide rail 521 facing the outer edge of the slide 52. Several sliders 53 are mounted within the curved guide rail 521 and are capable of sliding relative to the slide 52. Each slider 53 is connected to a clamping block 54. When the clamping drive 51 drives the slide 52, the slider 53 slides within the guide rail 521, thereby driving all the clamping blocks 54 to clamp or release.

[0047] In a specific embodiment, each of the clamping blocks 54 is centrally symmetrically distributed along the center of the slide 52 (or other symmetrical distribution methods can be used according to actual needs). This distribution method can evenly distribute the clamping force around the radioactive metal waste, avoiding deformation or slipping of the waste due to uneven clamping force. In a specific embodiment, the clamping block 54 includes a support portion 541 and a clamping portion 542 connected to the support portion 541. The support portion 541 is fixedly connected to the slide 53 to provide stable support for the clamping portion 542. The contact surface between the clamping portion 542 and the radioactive metal waste to be clamped is a plane or arc surface extending along the axial direction. When processing cylindrical radioactive metal waste, the clamping block 54 with an arc contact surface can better fit the waste surface, increase the contact area, and improve the stability of the clamping; while for square or other regularly shaped waste, the clamping block 54 with a flat contact surface can provide a uniform clamping force to ensure that the waste is firmly clamped.

[0048] The intelligent control system establishes communication connections with the clamping unit 50, the rotation drive unit 30, the positioner 60 and the photoelectric sensor 70 respectively, and can obtain and process various types of information in real time, and accurately control the actions of each component according to preset programs and actual work requirements.

[0049] The positioner 60 is used to determine the current position of the rotating disk 20. It is installed at an appropriate location on the clamping unit 50, the receiving sleeve 40, or the fixed plate 10. Using a high-precision angle encoder or other positioning sensor, it can accurately detect the rotation angle and position of the rotating disk 20 in real time and transmit this data to the intelligent control system. Based on the information provided by the positioner 60, the intelligent control system determines whether the rotating disk 20 has reached the desired position. This system then precisely controls the operation of the rotary drive unit 30, ensuring that the receiving sleeve 40 and the radioactive metal waste arrive at their designated locations, meeting the requirements of various disposal processes.

[0050] The photoelectric sensor 70 is used to check whether the clampable position has been reached. It is installed at an appropriate position on the clamping unit 50, the receiving sleeve 40, or the fixed plate 10. When the radioactive metal waste is placed in the receiving sleeve 40, the photoelectric sensor 70 can detect the position and status of the waste and transmit the signal to the intelligent control system. The intelligent control system determines whether the clamping conditions are met based on the feedback information from the photoelectric sensor 70. If the clampable position has been reached, the intelligent control system sends a command to the clamping unit 50, controlling the clamping drive 51 to start, driving the clamping block 54 to perform the clamping action; if the clampable position has not been reached, the intelligent control system will continue to control the rotation drive unit 30 or other related components to make adjustments until the clamping conditions are met.

[0051] Example 1

[0052] Processing of cylindrical radioactive metal waste

[0053] In a nuclear power plant's waste processing workshop, a used cylindrical nuclear fuel rod needs to be disposed of. First, an operator inputs the fuel rod's approximate dimensions and weight into the intelligent control system via a remote terminal. Upon receiving the instructions, the intelligent control system controls the rotating disk to the appropriate initial position, aligning the guide of the receiving sleeve with the placement direction of the fuel rod.

[0054] The operator then uses a robotic arm to slowly move the fuel rod over the receiving sleeve. Guided by the guide, the fuel rod smoothly falls into the receiving portion of the receiving sleeve. Because the diameter of the receiving portion is smaller than the fuel rod, the fuel rod is stably received on the receiving portion. Next, the intelligent control system calculates the appropriate clamping force based on pre-entered parameters and issues a command to the clamping unit. The clamping drive activates, driving the slide. The slide slides within the curved guide rail, driving several clamping blocks toward the center, firmly clamping the fuel rod with uniform force.

[0055] During subsequent handling, if the nuclear fuel rods need to be processed at different angles, the intelligent control system issues commands to the rotary drive unit. The rotary drive unit drives the worm, which, through the turbine drive, rotates the rotating disk and receiving sleeve to the specified angle. Thanks to the self-locking properties of the worm-turbine drive, the rotating disk automatically locks when the specified angle is reached, ensuring the stability of the nuclear fuel rods during handling. Once handling is complete, the intelligent control system instructs the clamping unit to release the clamping block, and the operator uses the robotic arm to remove the processed nuclear fuel rods from the clamp, completing the entire handling process.

[0056] Example 2

[0057] Treatment of irregularly shaped radioactive metal waste

[0058] For irregularly shaped fragments of radioactive metal equipment, the relevant information is first input into the intelligent control system via a remote terminal. The intelligent control system then adjusts the rotating disk and receiving sleeve to the appropriate position. The bell-shaped design of the guide section effectively adapts to the irregular shape of the fragments, facilitating their smooth entry into the receiving sleeve. Once the fragments fall into the receiving sleeve, the elastic material at the receiving end tightly envelops them, providing a preliminary fixation.

[0059] Next, the intelligent control system precisely controls the movement of the gripping unit based on the shape and size of the fragment. The gripping drive drives the slide, enabling the gripping blocks at different positions to adaptively grip the fragment according to its shape, ensuring a secure hold. During the subsequent rotation and handling process, the rotation drive unit and the intelligent control system work together to perform multi-angle handling of the fragment according to a pre-defined program. Once handling is complete, the gripping blocks are released, and the fragment is removed, completing the handling operation.
