[0046] Figure 1 and Figure 2 The illustration shows a nuclear power plant high radioactive waste containment device 10 in some embodiments of the present invention. The nuclear power plant high radioactive waste containment device 10 is used to contain and seal underwater (below the water surface of the reactor core) radioactive waste (such as detectors).

[0047] The nuclear power plant high-radioactivity waste containment device 10 includes a containment mechanism 1 and a sealing mechanism 2, the sealing mechanism 2 being detachably connected to the containment mechanism 1. Understandably, the containment mechanism 1 is used to contain radioactive waste.

[0048] like Figures 1 to 4 As shown, the storage mechanism 1 includes a storage tube 11, a base 12 and an upper seat 13. The base 12 and the upper seat 13 are respectively disposed at both ends of the storage tube 11. The inner wall surface of the base 12 and the storage tube 11 together define the radioactive material storage space 14. The upper seat 13 has a through hole 131.

[0049] Understandably, the collection cylinder 11 serves as the primary container for holding radioactive waste from the reactor. It provides a safe storage space for radioactive materials. The base 12, together with the collection cylinder 11, defines the radioactive material storage space 14, ensuring a bottom seal to prevent radioactive waste from leaking into the external environment. The upper seat 13 connects to the sealing mechanism 2, while also ensuring a top seal and supporting the installation and removal of the cover 21.

[0050] like Figures 3 to 10 As shown, the sealing mechanism 2 includes a cover 21 and a movable lock cylinder 22. The movable lock cylinder 22 is movably mounted on the cover 21. The cover 21 is detachably mounted inside the through hole 131. The movable lock cylinder 22 is provided with a torque input end 2221. The torque input end 2221 allows torque input to make the movable lock cylinder 22 rotate, thereby locking the movable lock cylinder 22 into the hole wall of the through hole 131, thus sealing the radioactive material storage space 14.

[0051] It can be understood that the cover body 21 is detachably covered in the through hole 131 of the upper seat 13, plays a role in closing the radioactive material storage space 14, and ensures that the internal radioactive material does not leak. The torque input end 2221 on the movable lock core 22 allows the torque to be applied by an external tool to drive the movable lock core to rotate, thereby achieving the tight locking or unlocking between the cover body 21 and the through hole 131, ensuring the effectiveness and reliability of the closure.

[0052] The storage space 14 is used for safe storage of radioactive waste, and ensures that the waste remains stable and isolated during underwater transportation. The through hole 131 is used to connect the closure mechanism 2, so that the radioactive material storage space 14 can be reliably closed, and subsequent operation and maintenance are also facilitated. The torque input end 2221 is provided, so that the movable lock core 22 can respond to the torque provided by the external tool, and then complete the locking or unlocking action, thereby simplifying the closure process and improving the operation efficiency.

[0053] It should be noted that the utility model realizes safe storage, closure and accurate transportation of radioactive waste through the cooperative work of the storage mechanism 1 and the closure mechanism 2. Not only the safety and convenience of the processing process are improved, but also the requirement of long-time storage of radioactive waste is met, and the safety of the waste in the whole management cycle is ensured. In addition, the compact and modular design of the utility model also enhances the flexibility and application range of the device.

[0054] As shown in Figures 3 to 10 As shown in FIG. 1, in some embodiments of the nuclear power high radioactive material storage device 10, a positioning column 211 is arranged on the cover body 21, a torque hole 212 is formed on the cover body 21, the torque hole 212 penetrates the positioning column 211, and a closing slot 213 and an opening slot 214 are formed on the positioning column 211.

[0055] The movable lock core 22 includes a blocking part 221, a guide column 222, an elastic part 223 and a locking part 224. The blocking part 221 is rotatably sleeved outside the positioning column 211, the torque input end 2221 is located on the guide column 222 and exposed in the torque hole 212, the guide column 222 is inserted into the torque hole 212, the elastic part 223 is sleeved outside the guide column 222 and located in the torque hole 212, and the locking part 224 is used to fix the relative position of the blocking part 221 and the guide column 222 in the circumferential direction. When the guide column 222 rotates, the blocking part 221 is driven to rotate by the locking part 224, so that the locking part 224 is driven by the elastic part 223 to correspondingly clamp into the closing slot 213 or the opening slot 214.

[0056] When the locking part 224 is located in the closing slot 213, the blocking part 221 is clamped to the hole wall of the through hole 131; when the locking part 224 is located in the opening slot 214, the blocking part 221 is separated from the hole wall of the through hole 131.

[0057] It can be understood that the positioning column 211 provides a mounting reference for the movable lock cylinder 22, ensuring that the blocking piece 221 is correctly sleeved and rotated. The torque hole 212 penetrates the positioning column 211, used to accommodate the guide column 222, and allows the torque input end 2221 to contact the external tool through the torque hole 212, realizing the operation of the movable lock cylinder 22. The cover closing groove 213 and the cover opening groove 214 are used to lock and unlock the position of the blocking piece 221, respectively. When the locking piece 224 is located in the cover closing groove 213, it ensures that the blocking piece 221 is firmly clamped to the hole wall of the through hole 131; when the locking piece 224 is located in the cover opening groove 214, the blocking piece 221 is separated from the hole wall, and the cover body 21 can be easily removed from the receiving barrel 11.

[0058] The blocking piece 221 plays a blocking and fixing role. It contacts or separates from the hole wall of the through hole 131, determining whether the radioactive material receiving space 14 is closed (i.e., whether the cover body 21 is locked). The torque input end 2221 on the guide column 222 is exposed in the torque hole 212, allowing torque to be applied by an external tool to drive the blocking piece 221 to rotate. The guide column 222 not only provides a rotation axis, but also ensures stable rotation of the blocking piece 221. The elastic piece 223 provides elastic support, enabling the locking piece 224 to automatically correspondingly clamp into the cover closing groove 213 or the cover opening groove 214 during rotation, enhancing the reliability and automation level of operation. The locking piece 224 is used to fix the relative position between the blocking piece 221 and the guide column 222, ensuring that they rotate synchronously. At the same time, the locking piece 224 is driven by the elastic piece 223, selectively clamping into the cover closing groove 213 or the cover opening groove 214 according to the rotation angle of the blocking piece 221, thereby completing the closing or opening action.

[0059] It should be noted that when it is necessary to close the radioactive material receiving space 14, the operator applies torque to the torque input end 2221 through an external tool, causing the guide column 222 to drive the blocking piece 221 to rotate until the locking piece 224 clamps into the cover closing groove 213. At this time, the blocking piece 221 tightly fits the hole wall of the through hole 131, ensuring that radioactive waste does not leak. When it is necessary to open the radioactive material receiving space 14, torque is again applied by an external tool, causing the guide column 222 to rotate in the opposite direction until the locking piece 224 clamps into the cover opening groove 214. At this time, the blocking piece 221 is separated from the hole wall of the through hole 131, and the cover body 21 can be easily removed, facilitating subsequent operation or maintenance.

[0060] As Figures 4 to 10As shown, in some embodiments of the nuclear high-radiation containing device 10, the blocking member 221 includes a fixed sleeve 2211 and a plurality of blocking strips 2212, the fixed sleeve 2211 is sleeved on the positioning column 211, the locking member 224 penetrates the fixed sleeve 2211, and each blocking strip 2212 is arranged on the outer wall of the circumferential edge of the fixed sleeve 2211; when the blocking member 221 rotates, each blocking strip 2212 can be clamped on the hole wall of the through hole 131 or separated from the hole wall of the through hole 131.

[0061] Understandably, the fixed sleeve 2211 is the main supporting structure of the blocking member 221. It not only provides the rotation axis, but also realizes the circumferential fixation with the guide column 222 through the locking member 224, ensuring synchronous rotation of the two. When the blocking member 221 rotates, the blocking strip 2212 can be clamped or separated from the hole wall of the through hole 131, thereby realizing the closing or opening of the radiation containing space 14.

[0062] It should be noted that when it is necessary to close the radiation containing space 14, the operator applies torque to the torque input end 2221 through an external tool, so that the guide column 222 drives the fixed sleeve 2211 to rotate. With the rotation of the fixed sleeve 2211, each blocking strip 2212 gradually approaches and finally tightly fits the hole wall of the through hole 131, forming an effective sealing barrier to prevent radioactive substances from leaking. At this time, the locking member 224 is clamped into the cover slot 213 under the action of the elastic member 223, ensuring that the blocking member 221 remains in the closed state.

[0063] When it is necessary to open the radiation containing space 14, the reverse torque is applied again through an external tool, so that the guide column 222 reversely rotates, driving the fixed sleeve 2211 and the blocking strip 2212 to rotate together. With the blocking strip 2212 separated from the hole wall of the through hole 131, the locking member 224 is automatically clamped into the cover slot 214 under the action of the elastic member 223, so that the blocking member 221 is in the open state, facilitating subsequent operation or maintenance.

[0064] As shown, Figures 4 to 10 In some embodiments of the nuclear high-radiation containing device 10, the blocking member 221 further includes a plurality of first reinforcing ribs 2213 and a plurality of second reinforcing ribs 2214, each first reinforcing rib 2213 is arranged one-to-one on each blocking strip 2212, each first reinforcing rib 2213 is connected to the fixed sleeve 2211, and each second reinforcing rib 2214 is arranged between every two adjacent blocking strips 2212. The two ends of each second reinforcing rib 2214 are respectively connected to two blocking strips 2212.

[0065] Understandably, the fixing sleeve 2211, as the main supporting structure of the stop component 221, is sleeved on the outside of the positioning post 211 and is circumferentially fixed to the guide post 222 by the locking component 224. Each baffle strip 2212 is used to clamp or disengage from the hole wall of the through hole 131 to achieve the closure or opening of the radioactive material storage space 14.

[0066] Each first reinforcing rib 2213 increases the rigidity and strength of the baffle strip 2212, ensuring that it will not deform or be damaged when subjected to high pressure environments or external impacts. They also provide additional support, allowing the baffle strip 2212 to fit more tightly against the wall of the through hole 131, enhancing the sealing effect.

[0067] A second reinforcing rib 2214 is provided between every two adjacent baffle strips 2212, and the two ends of each second reinforcing rib 2214 are respectively connected to the two baffle strips 2212. These second reinforcing ribs 2214 not only enhance the overall structural stability of the stop component 221, but also provide additional support between the baffle strips 2212 to prevent displacement or loosening during operation, and ensure the synchronous rotation performance of the entire stop component 221.

[0068] like Figures 4 to 10 As shown, in some embodiments of the nuclear power plant high radioactive material containment device 10, the torque input end 2221 includes a torque protrusion 2222, which is disposed at the end of the guide post 222 and exposed in the torque hole 212.

[0069] Understandably, the torque protrusion 2222 is used to contact an external tool (such as a torque wrench) or an external torque input device to receive and transmit rotational force; specifically, the external tool can drive the guide post 222 to rotate by pressing against the torque protrusion 2222.

[0070] like Figure 4 and Figure 5 As shown, in some embodiments of the nuclear power plant high radioactive material storage device 10, a locking flange 132 is provided on the wall of the through hole 131, and the locking flange 132 is used to lock the movable lock cylinder 22.

[0071] Understandably, the locking flange 132 is used to provide an additional mechanical locking point so that the baffle strip 2212 on the stop member 221 can more securely engage the through hole 131.

[0072] like Figure 4 and Figure 5As shown, in some embodiments of the nuclear high-level radioactive material storage device 10, the storage cylinder 11 includes a plurality of cylinder bodies 111 and a plurality of connecting flanges 112, each cylinder body 111 has one connecting flange 112 at each end, each cylinder body 111 is arranged in a straight line, and the adjacent two cylinder bodies 111 are connected by the connecting flange 112. The two connecting flanges 112 at both ends of the storage cylinder 11 are connected to the base 12 and the upper seat 13 respectively, and the inner wall surface of each cylinder body 111 and the base 12 jointly define the radioactive material storage space 14.

[0073] Understandably, the plurality of cylinder bodies 111 are arranged in a straight line one by one to constitute the main part of the storage cylinder 11. Each cylinder body 111 has one connecting flange 112 at each end for connection with other cylinder bodies 111 or the base 12 and the upper seat 13. This modular design allows the storage cylinder 11 to be flexibly adjusted in length according to actual needs, adapting to different actual use requirements.

[0074] The adjacent two cylinder bodies 111 are reliably mechanically connected by the connecting flange 112. The two connecting flanges 112 at both ends of the storage cylinder 11 are connected to the base 12 and the upper seat 13 respectively, ensuring that the entire storage cylinder 11 forms a complete sealed space. The design of the connecting flange 112 not only provides stable connection, but also facilitates disassembly and maintenance.

[0075] As shown, Figures 3 to 5 In some embodiments of the nuclear high-level radioactive material storage device 10, the storage mechanism 1 further includes a plurality of angle steels 15, each angle steel 15 is arranged one by one at each corner of the storage cylinder 11, one end of each angle steel 15 is connected to the base 12, and the other end of each angle steel 15 is connected to the upper seat 13.

[0076] Understandably, the main role of the angle steel 15 is to enhance the overall structural strength and stability of the storage cylinder 11, ensuring its long-term stable operation in a high-pressure underwater environment. The angle steel 15 provides additional support to the storage cylinder 11, enhancing its overall mechanical strength, especially at the corners, which are usually stress concentration areas. The presence of the angle steel 15 can effectively prevent the storage cylinder 11 from deforming or being damaged due to external pressure or impact, ensuring the safety and reliability of the device. The angle steel 15 not only connects the base 12 and the upper seat 13, but also reinforces the vertical stability of the entire storage mechanism 1, reducing the possibility of shaking or deviation during underwater operation, ensuring the stability of the device under various working conditions.

[0077] As shown, Figures 3 to 5 In some embodiments of the nuclear high-level radioactive material storage device 10, each cylinder body 111 includes two oppositely arranged U-shaped plates 113, and the two U-shaped plates 113 jointly define a cylindrical space open at both ends.

[0078] As can be understood, each cylinder 111 is composed of two oppositely arranged U-shaped plates 113, which are fixed together by connecting flanges 112 or other connecting means, forming an open-ended cylindrical space. In this way, not only the manufacturing process of the cylinder 111 is simplified, but also good structural strength and stability are provided.

[0079] It should be noted that the use of two U-shaped plates 113 to form the cylinder 111 greatly simplifies the manufacturing process and reduces production costs. Compared with the traditional single-piece forming method, the design of the U-shaped plate 113 makes production and assembly easier, and also facilitates quality control. Secondly, the cooperation between the two U-shaped plates 113 forms a solid cylindrical structure, enhancing the overall mechanical strength of the cylinder 111. This structure can effectively resist external pressure and impact, ensuring long-term stable operation in high-pressure underwater environments.

[0080] As shown in Figure 1 , Figure 11 , Figure 12 and Figure 13 , the storage and transportation device includes a nuclear power high-radiation storage device 10, a clamping device 1a, a transportation device 2a, and a cover opening and closing device 3a. The clamping device 1a is used to place the nuclear power high-radiation storage device 10 on the transportation device 2a, the transportation device 2a is used to move the nuclear power high-radiation storage device 10, and the cover opening and closing device 3a is used to disassemble and assemble the cover 21.

[0081] As can be understood, the nuclear power high-radiation storage device 10 is used to safely store and seal radioactive waste underwater (below the water surface of the reactor core). It includes a storage mechanism 1 and a sealing mechanism 2, which ensures that the radioactive waste is stored stably in the underwater environment for a long time, and can be easily sealed and opened.

[0082] The clamping device 1a is used to accurately place the nuclear power high-radiation storage device 10 on the transportation device 2a, ensuring that it remains stable during transportation. The clamping device 1a usually has automatic positioning and fixing functions, and can be accurately operated in the underwater environment to ensure that the nuclear power high-radiation storage device 10 does not shift or fall off due to external factors.
