Description

Technical Field

[0001] This invention belongs to the field of radioactive waste treatment technology and relates to remote control, specifically a remote opening and closing device for a high-radiation waste container. Background Technology

[0002] Highly radioactive waste is extremely polluting and destructive, posing a significant potential threat to the environment. Currently, much of this waste is temporarily stored in standard containers during transport. In a radiation environment, the handling of highly radioactive waste requires strict safety measures. Opening and closing containers cannot be done manually; it must be done remotely to ensure operational safety and thus achieve safe waste disposal.

[0003] In existing technologies, tools for opening and closing waste containers include robotic arms, fully automated opening and closing devices, and remote monitoring robots. These devices are mostly very expensive to build and suitable for complex assembly line operations, but they suffer from high maintenance costs and high failure rates. Therefore, there is an urgent need to design a remote opening and closing control device that is simple to operate, low in cost, and easy to maintain, so as to avoid radiation damage to workers through remote manual operation. Summary of the Invention

[0004] The purpose of this invention is to provide a remote opening and closing device for high-radioactive waste containers. It does not use existing technologies such as robotic arms, fully automatic opening and closing equipment, or remote monitoring robots, thus solving the problems of high manufacturing cost, high maintenance cost, and high failure rate of remote opening and closing devices. It has the advantages of low manufacturing cost, simple operation, easy maintenance, and high practicality.

[0005] This invention is achieved using the following technical solution: A remote-controlled opening and closing device for a high-radioactivity waste container includes an outer sleeve, an upper flange fixedly connected to the upper end of the outer sleeve, a transition shaft adapted to pass through the center of the upper flange, a lower flange fixedly connected to the lower end of the outer sleeve, a central connecting rod connected to the lower end of the transition shaft, the lower end of the central connecting rod adapted to pass through the lower flange, and a rotating handle connected to the upper end of the transition shaft; a spring support seat fixed to the lower part of the central connecting rod, a first spring fitted onto the lower part of the central connecting rod, the upper end of the first spring abutting against the spring support seat, and the lower end abutting against the upper surface of the lower flange; a synchronously rotatable switching rod connected to the lower end of the central connecting rod, a switching groove provided on the lower end face of the switching rod, and a synchronously rotatable lifting plate mounted on the switching rod.

[0006] The top of the high-radioactivity waste container is an upper tube seat, and the cover fits inside the upper tube seat. The cover has a square groove structure, and a rotating component is installed in the center of the square groove. The square groove has a recess that can engage with a lifting plate. Rotating the rotating component allows the cover to be opened or closed.

[0007] Before use, adjust the switch slot and the lifting plate to match the square slot and rotating part on the cover. Then insert the switch slot into the rotating part, rotate and press down the rotating handle (compressing the first spring), so that the central connecting rod drives the switch slot to rotate and the rotating part opens. The lifting plate rotates synchronously and is inserted into the groove. Lift the connection between the switch cover device and the cover body to complete the opening of the cover.

[0008] When closing the cover, first connect the cover switch device to the cover body and lift it. Adjust the cover body to align with the high-radioactive waste container. Then, lower the cover body into the upper tube seat to close it with the high-radioactive waste container below. Rotate and press down the rotating handle to make the central connecting rod drive the switch slot to rotate and close the rotating part. The lifting plate rotates synchronously away from the cover body groove. Lift the cover switch device to complete the closing of the cover.

[0009] As a further technical solution, the lower flange is connected to a positioning plate, which is equipped with positioning pins, guide pins, and support columns corresponding to the part of the cover to be opened. This is used for docking and positioning the cover opening / closing tool with the upper pipe seat of the high-radioactivity waste container.

[0010] As a further technical solution, a connecting sleeve is fixedly provided at the outlet end of the lower flange, a stepped surface is provided on the switch rod, a sliding sleeve is fitted on the switch rod, and the sliding sleeve is suspended at the stepped surface of the switch rod through an annular protrusion in its upper part. A guide key is provided between the switch rod and the sliding sleeve to achieve synchronous rotation; a second spring is fitted on the switch rod, with the upper end of the second spring abutting against the connecting sleeve and its lower end abutting against the sliding sleeve; the lifting plate is integrally located on the sliding sleeve.

[0011] As a further technical solution, the upper surface of the upper flange is provided with an installation opening indicator and a disassembly opening indicator, and a pointer is fixedly mounted on the transition shaft; the upper part of the outer sleeve is symmetrically provided with two U-shaped grooves, one side of which is a long hole and the other side is a short hole; the upper part of the central connecting rod is provided with a through hole, and a pin is inserted into the through hole, with both ends of the pin protruding from the U-shaped grooves on both sides; the central connecting rod is kept in an upward state under the action of the first spring, and when the pointer points to the disassembly opening indicator, the pin is located at the upper part of the long hole of the U-shaped groove; similarly, when the pointer points to the installation opening indicator, the pin is located at the upper part of the short hole of the U-shaped groove. The U-shaped groove, through its specific contour structure, forms a kinematic pair with the inner structure of the switch cover tool, and provides bidirectional constraint on the motion freedom of the inner layer of the switch cover tool: the upper and lower inner walls of the U-shaped groove form a stop surface, restricting the axial vertical travel of the inner structure of the switch cover tool; the inner walls on both sides of the U-shaped groove form guide boundaries, suppressing the radial horizontal displacement of the inner structure of the switch cover tool.

[0012] As a further technical solution, when the pointer moves from the installation cover opening indicator position to the disassembly cover opening indicator position, the rotation angle of the central connecting rod is 45 degrees.

[0013] As a further technical solution, the upper part of the outer sleeve is provided with a protective sleeve in the U-shaped groove area, and the two ends of the pin protrude through the protective sleeve.

[0014] As a further technical solution, the outer sleeve includes an upper sleeve and a lower sleeve; an upper inner bushing is fixedly assembled inside the bottom end of the upper sleeve, and an upper annular protrusion protruding outside the bottom end of the upper sleeve is provided at the bottom end of the upper sleeve; an internal threaded sleeve is movably assembled outside the bottom end of the upper sleeve, and the internal threaded sleeve is suspended from the upper annular protrusion through its inner stepped surface; a lower inner bushing is fixedly assembled inside the upper end of the lower sleeve, and an external threaded sleeve is fixedly assembled outside it; after the internal threaded sleeve and the external threaded sleeve are connected, the upper sleeve and the lower sleeve form an outer sleeve.

[0015] As a further technical solution, the central connecting rod is adapted to pass through the upper inner bushing and the lower inner bushing. This provides precise guiding space for the axial movement of the upper and lower connecting rod's male and female couplings, ensuring stable movement trajectories and preventing the connection from falling off.

[0016] As a further technical solution, the central connecting rod includes an upper connecting rod and a lower connecting rod; the lower end of the upper connecting rod is provided with a guide male buckle, and the upper end of the lower connecting rod is provided with an elastic female buckle. After the guide male buckle is inserted into the elastic female buckle, the upper connecting rod and the lower connecting rod form a central connecting rod.

[0017] As a further technical solution, the upper flange is symmetrically provided with two arc-shaped slots, and a guide slider is provided in the arc-shaped slots, with a lifting ring between the two guide sliders.

[0018] The operation process of this invention is as follows: Opening process: S11: Adjust the pointer to the installation cover indicator position; ensure the pin is accurately positioned in the long hole of the U-shaped groove; verify that the edges of the lifting plate and the positioning plate are parallel, and confirm that the switch groove direction of the switch rod is in the diagonal direction of the positioning plate.

[0019] S12: Use lifting equipment to connect the lifting rings and lift the switch cover device to the working position.

[0020] S1.3: The operator, in conjunction with the vision system around the high-radioactive waste container, manually adjusts the switch cover device so that the front end of the guide pin of the positioning plate is directly aligned with the docking interface of the upper pipe seat; at the same time, the lifting plate is inserted into the square groove of the cover body, and the switch groove of the switch rod is precisely docked with the rotating part.

[0021] S14: The operator manually operates the rotating handle, pressing down and rotating it counterclockwise by 45° to change the cover from the "installed and closed" state to the "disassembled and opened" state. The lifting plate rotates into the rotating groove of the square slot of the cover, with the edge of the lifting plate forming a 45° angle with the edge of the positioning plate. The direction of the switch groove of the switch rod is parallel to the side length direction of the positioning plate, achieving a tight connection between the switch cover device and the cover. At this time, the pin is positioned at the short hole of the U-shaped groove. During the opening process, the rotating component drives the cross to rotate. After the cross rotates counterclockwise by 45°, it loosens the seal on the cover, and the high-radioactive waste container separates from the cover.

[0022] S15: The connection between the hoisting switch cover device and the cover body, and the cover body is transferred to a temporary storage location.

[0023] Closing process: S21: Using lifting equipment, connect the lifting ring and move the connection between the lifting switch cover device and the cover body to the working position. At this time, the lifting plate is inserted into the cover body, with the edge of the lifting plate forming a 45° angle with the edge of the cover body, and the switch groove of the switch rod aligns with the rotating part. The pointer indicates the "disassemble and open" state; simultaneously, the pin is positioned at the short hole of the U-shaped groove, the edge of the lifting plate forms a 45° angle with the edge of the positioning plate, and the direction of the switch groove of the switch rod is parallel to the side length direction of the positioning plate.

[0024] S22: The operator, in conjunction with the vision system around the container, manually adjusts the opening and closing cover device to ensure that the guide pin of the positioning plate is directly aligned with the docking interface of the upper pipe seat of the high-radioactive waste container.

[0025] S23: The operator manually operates the rotating handle, pressing down and rotating it 45° clockwise to change the cover from the "disassembly and opening" state to the "installation and closing" state. The cover connects to the upper tube seat of the high-radioactive waste container, completing the closing action. At the same time, the pin is positioned in the elongated hole of the U-shaped groove, the edge of the lifting plate is parallel to the edge of the positioning plate, and the direction of the switch groove of the switch rod is parallel to the diagonal direction of the positioning plate.

[0026] S24: The hoisting device transfers the switch cover to its storage location for future use.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects: The remote cover opening and closing device of the present invention does not use robotic arms, fully automatic cover opening and closing equipment, remote monitoring robots, etc., and solves the problems of high manufacturing cost, high maintenance cost and high failure rate of remote cover opening and closing devices; it adopts a simple mechanical structure to open the cover and has the advantages of low manufacturing cost, simple operation, easy maintenance and strong practicality.

Detailed Implementation

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0051] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0052] refer to Figures 1-19 As shown, a remote opening and closing device for a high-radiation waste container includes an outer sleeve 60. An upper flange 301 is fixedly connected to the upper end of the outer sleeve 60, and a transition shaft 202 is fitted through the center of the upper flange 301. A lower flange 802 is fixedly connected to the lower end of the outer sleeve 60. A central connecting rod 70 is connected to the lower end of the transition shaft 202, and the lower end of the central connecting rod 70 is fitted through the lower flange 802. A rotating handle 201 is connected to the upper end of the transition shaft 202. A spring support seat 901 is fixed to the lower part of the central connecting rod 70, and a first spring 902 is fitted onto the lower part of the central connecting rod 70. The upper end of the first spring 902 abuts against the spring support seat 901, and its lower end abuts against the upper surface of the lower flange 802. A synchronously rotatable switching rod 906 is connected to the lower end of the central connecting rod 70. A switching groove 9061 is provided on the lower end face of the switching rod 906, and a synchronously rotatable lifting plate 904 is mounted on the switching rod 906. The following is a detailed explanation of each part of the opening and closing device: 1. Lifting and hoisting operation section: refer to Figures 7-9 As shown, the upper flange 301 is connected to the top of the upper sleeve 601 via an outer liner 505. The lower shaft portion of the upper flange 301 is lined inside the upper sleeve 601, and the corresponding outer sleeve 601 is covered by the outer liner 505. A circular series of mounting holes are evenly formed on the surfaces of the outer liner 505 and the upper sleeve 601. High-strength bolts are inserted into these holes to achieve a rigid connection with the upper sleeve 601, forming a composite load-bearing structure. The upper flange 301 has two symmetrical arc-shaped slots 3011, each containing a guide slider 102. The two guide sliders 102 are hinged together by a pin with a lifting ring 101.

[0053] refer to Figure 7 and 10 As shown in Figure 11, the upper surface of the upper flange 301 is provided with an installation cover opening indicator 3012 and a disassembly cover opening indicator 3013, and a pointer 302 is fixedly installed on the transition shaft 202. The upper part of the outer sleeve 60 is symmetrically provided with two U-shaped grooves 603, and a protective sleeve 401 (as shown in Figure 11) is provided around the outer periphery of the U-shaped grooves 603. Figure 8 As shown), the U-shaped groove 603 has a long hole 6031 on one side and a short hole 6032 on the other side; the upper part of the central connecting rod 70 is provided with a through hole 703 (as shown). Figure 12As shown), a pin 402 is inserted into the through hole 703. The two ends of the pin 402 pass through the U-shaped grooves 603 on both sides and through the sheath 401. The central connecting rod 70 remains in an upward state under the action of the first spring 902.

[0054] like Figure 11 As shown, when pointer 302 points to the disassembly / opening indicator 3013, pin 402 is located above the elongated hole 6031 of the U-shaped groove 603; similarly, as Figure 10 As shown, when pointer 302 points to the installation cover opening indicator position 3012, pin 402 is located on the upper part of the short hole 6032 of the concave groove 603.

[0055] like Figure 8 As shown, the U-shaped groove 603, through its specific contour structure, forms a kinematic pair with the inner structure of the switch cover tool, providing bidirectional constraints on the motion freedom of the inner structure: the upper and lower inner walls of the U-shaped groove 603 form stop surfaces, restricting the axial vertical travel of the inner structure; the inner walls on both sides of the U-shaped groove 603 form guide boundaries, suppressing the radial horizontal offset of the inner structure. This structure precisely controls the motion freedom of the inner structure through geometric constraints, ensuring its directional movement within the design range.

[0056] Preferably, when the pointer 302 points from the installation cover opening indicator 3012 to the disassembly cover opening indicator 3013, the rotation angle of the central connecting rod 70 is 45 degrees.

[0057] 2. Force transmission part of the sleeve: refer to Figures 12-14 As shown, the outer sleeve 60 includes an upper sleeve 601 and a lower sleeve 602. An upper inner bushing 503 is fixedly fitted inside the bottom end of the upper sleeve 601. An upper annular protrusion 5031 protrudes from the bottom end of the upper inner bushing 503. An internally threaded sleeve 502 is movably fitted outside the bottom end of the upper sleeve 601. A ring of mounting holes is correspondingly formed on the upper sleeve 601 and the internally threaded sleeve 502, and high-strength bolts are inserted into these mounting holes to achieve a rigid connection with the upper sleeve 601. The internally threaded sleeve 502 is suspended from the upper annular protrusion 5031 via its inner stepped surface. A lower inner bushing 504 is fixedly fitted inside the upper end of the lower sleeve 602, and an externally threaded sleeve 501 is fixedly fitted outside it. A ring of mounting holes is correspondingly formed on the lower sleeve 602 and the externally threaded sleeve 501, and high-strength bolts are inserted into these mounting holes to achieve a rigid connection with the lower sleeve 602. After the internal threaded sleeve 502 is connected to the external threaded sleeve 501, the upper sleeve 601 and the lower sleeve 602 form an outer sleeve (e.g. Figure 14 (As shown).

[0058] refer to Figure 13As shown, the central connecting rod 70 includes an upper connecting rod 701 and a lower connecting rod 702. The lower end of the upper connecting rod 701 is provided with a guide male buckle 7011, and the upper end of the lower connecting rod 702 is provided with an elastic female buckle 7021. The guide male buckle 7011 is inserted into the elastic female buckle 7021 (with a gap of 0.05-0.1mm) to form the central connecting rod. The central connecting rod 70 adapts to pass through the upper inner bushing 503 and the lower inner bushing 504, providing precise guiding space for the axial movement of the female and male buckles of the upper connecting rod 701 and the lower connecting rod 702, ensuring stable movement trajectory, and preventing the connection from falling off.

[0059] 3. Opening and closing cover section: refer to Figures 2-6 As shown, the lower flange 802 is installed at the tail of the lower sleeve 602 via the outer liner 505 (as shown). Figure 3 (As shown). The upper shaft portion of the lower flange 802 is lined inside the lower sleeve 602, and the corresponding lower sleeve 602 is covered by an outer liner 505. A circular series of mounting holes are evenly spaced on the surfaces of the outer liner 505 and the lower sleeve 602. High-strength bolts are inserted into these holes to achieve a rigid connection with the lower sleeve 602, forming a composite load-bearing structure. Simultaneously, the clearance tolerance between the lower connecting rod 702 and the center hole of the lower flange 802 is maintained at H8 / f7; the surface roughness of the center hole of the lower flange 802 is less than or equal to 1.6, ensuring smooth and unobstructed vertical movement of the lower connecting rod 702.

[0060] like Figure 4 As shown, a positioning plate 801 is bolted to the lower surface of the lower flange 802. Support tubes 804 and spring caps 805 are installed on one set of diagonal sections of the positioning plate 801. Another set of diagonal holes are drilled, with the hole spacing precisely matching the mating interface A21 of the upper pipe seat A2 of the container to ensure mating accuracy. A positioning pin 806 is installed in one hole, and a support leg 807 (e.g., ...) is installed in the other hole. Figure 15 (As shown). Used for docking and positioning of the cover opening tool with the upper tube seat A2 of the high-radioactivity waste container.

[0061] The support tube 804 is installed on the lower surface of the positioning plate 801 and the spring cap 805 on the upper surface of the positioning plate 801 are connected by threads (e.g., Figure 5 As shown, an adjustable elastic guide mechanism is formed, with a spring inside the spring cap 805 providing axial elastic compensation. A guide pin 803 is installed inside the support tube 804, and the guide pin 803 and the support tube 804 are fixed with a small clearance fit, with a clearance of less than 0.1mm, to ensure motion guidance accuracy.

[0062] like Figure 15 As shown, during the docking operation, the front end of the guide pin 803 docks and positions itself with the docking interface A21 of the upper tube seat A2 of the high-radioactive waste container, and the spring cap 805 absorbs the axial deviation during the docking process to ensure reliable contact.

[0063] refer toFigure 2 and 6 As shown, a connecting sleeve 903 is fixedly provided at the outlet end of the lower flange 802. A stepped surface is provided on the switch rod 906. A sliding sleeve 905 is fitted on the switch rod 906. The sliding sleeve 905 is suspended at the stepped surface of the switch rod 906 through the engagement of the annular protrusion 9051 in its upper part. A guide key 908 is provided between the switch rod 906 and the sliding sleeve 905 to achieve synchronous rotation. A second spring 907 is fitted on the switch rod 906. The upper end of the second spring 907 abuts against the connecting sleeve 903, and its lower end abuts against the sliding sleeve 905. The lifting plate 904 is integrally located on the sliding sleeve 905.

[0064] refer to Figures 17-19 The diagram shows the structure of the cover A1 of a high-radioactivity waste container. The top of the container is an upper tube seat A2, and the cover A1 fits inside the upper tube seat A2. A square groove A11 is provided on the cover A1. A positioning seat A13 is installed on the lower surface of the cover A1. A cross-shaped element A14, which limits the opening and closing of the cover, is positioned between the positioning seat A13 and the cover A1. A rotating component A12 is installed at the center of the square groove A11. The rotating component A12 is connected to the positioning seat A13 to limit the position of the cross-shaped element A14. Rotating the rotating component A12 changes the position of the cross-shaped element A14, thus opening and closing the cover A1 (e.g., ...). Figure 19 (As shown).

[0065] The remote switch cover device of the present invention is installed inside the upper tube seat A2 and cooperates with the cover body A1 during use. Its operation process is as follows: 1. Opening process S11: Adjust pointer 302 to the installation cover opening indicator position 3012 (e.g., ... Figure 10 (As shown); ensure that the pin 402 is accurately positioned at the elongated hole 6031 of the U-shaped groove 603 (as shown). Figure 8 (As shown); verify that the edges of the hoisting plate 904 and the positioning plate 801 are parallel, and confirm that the direction of the switch groove 9061 of the switch rod 906 is in the diagonal direction of the positioning plate 801.

[0066] S12: Use lifting equipment to connect lifting ring 101 and lift the switch cover device to the working position.

[0067] S1.3: The operator, using the vision system around the high-radioactive waste container, manually adjusts the cover opening and closing device so that the front end of the guide pin 803 of the positioning plate 801 is directly aligned with the docking interface A21 of the upper pipe seat A2; simultaneously, the lifting plate 904 is inserted into the square groove A11 of the cover body A1, and the opening groove 9061 of the switch rod 906 is precisely aligned with the rotating part A12 (e.g., Figure 15 (As shown).

[0068] S14: The operator manually operates the rotating handle 201, presses it down and rotates it counterclockwise by 45° to change the cover A1 from the "installation and closing" state to the "disassembly and opening" state. The lifting plate 904 rotates into the rotating groove of the square groove A11 of the cover A1. The edge of the lifting plate 904 forms a 45° angle with the edge of the positioning plate 801. The direction of the switch groove 9061 of the switch rod 906 is parallel to the side length direction of the positioning plate 801, realizing a tight connection between the switch cover device and the cover A1. At this time, the pin 402 is positioned at the short hole position of the U-shaped groove 603.

[0069] Specifically: During the opening process, the rotating component A12 drives the cross A14 to rotate. After the cross A14 rotates 45° counterclockwise, it loosens the seal on the cover A1, and the high-radioactive waste container separates from the cover A1.

[0070] S15: Lift the connection between the switch cover device and the cover body A1, and transfer the cover body A1 to a temporary storage location.

[0071] 2. Closing process S21: Use lifting equipment to connect lifting ring 101 and move the connecting body between the switch cover device and the cover body A1 to the working position.
