Description

Technical Field

[0001] This invention relates to the field of nuclear fuel cycle and irradiation effects technology, and more specifically, to a lead container suitable for transporting portable high-intensity radiation samples in a LOCA shielded glove box. Background Technology

[0002] The study of radioactive samples is crucial to the large-scale development and application of nuclear energy. The short-distance, inter-regional transport of highly radioactive samples (such as uranium and plutonium-based nuclear fuel samples), precise docking with LOCA shielded glove boxes, and sample loading and unloading operations are core aspects of ensuring experimental safety and advancing nuclear materials research and development. These samples possess extremely strong radiation characteristics, and their transport and handling processes must strictly prevent radiation leakage and avoid direct exposure to personnel. Improper handling can not only cause irreversible radiation damage to experimental personnel but also potentially contaminate the experimental environment and even affect the continuity of the entire research project.

[0003] The existing lead containers used for transporting samples for docking glove boxes have multiple technical shortcomings in the entire operation process, from docking preparation to sample loading and unloading, which seriously affect operational efficiency and safety: In the initial adaptation stage of docking glove boxes, the lead container interface size is fixed. If the interface diameter or flange type of the target glove box differs, the entire lead container must be replaced or the interface components must be disassembled and replaced, which not only prolongs the initial preparation time but also significantly increases equipment maintenance costs. During the docking alignment stage, the operation relies entirely on manual visual observation and judgment. If the trolley is not placed evenly, causing a height difference or horizontal misalignment between the lead container and the glove box, the trolley support legs must be repeatedly adjusted for correction, which is not only time-consuming and labor-intensive but also... Visual misjudgment can easily cause collisions and damage between the lead container interface and the glove box, further increasing operational risks. Even after initial alignment, during the final docking process, the reliance on a single set of load-bearing slide rails can lead to lateral displacement of the lead container due to rail gaps, requiring multiple push-pull adjustments to ensure precise interface fitting, significantly slowing down the docking process. Furthermore, in the subsequent sample loading and unloading stages, existing push-pull rods are mostly designed with fixed lengths, unable to adapt to glove box sample inlet channels of varying depths, necessitating frequent replacements of push-pull rods of the appropriate specifications. During transport, the lack of a stable fixing structure for the push-pull rods makes them susceptible to shaking due to road bumps, potentially causing sample damage and posing a safety hazard of radioactive material leakage. These interconnected technical pain points throughout the entire process collectively restrict the adaptability, ease of operation, and safety of transport lead containers, making it difficult to meet the requirements for efficient and safe transport operations in nuclear fuel experiments. Summary of the Invention

[0004] The purpose of this invention is to provide a movable high-intensity discharge sample transport lead container suitable for LOCA shielded glove box, which solves the problems of poor interface compatibility, difficult docking, horizontal displacement, incompatible push-pull rods, and unsafe transport of existing lead containers.

[0005] This invention is achieved through the following technical solution: a movable high-powered radiation sample transport lead container suitable for LOCA shielded glove box, comprising a transport vehicle, a lead container horizontally slidably connected to the transport vehicle, a shielding cavity provided inside the lead container, a push-pull rod axially movably connected to the rear end of the lead container, a sample compartment for loading high-powered radiation samples provided at one end of the push-pull rod inside the shielding cavity, a first connector connected to the front end of the lead container, a second connector for mating with the glove box being detachably connected to the end of the first connector, a shielding valve provided inside the first connector, a plurality of laser emitters arranged circumferentially on the outer side of the second connector, a plurality of positioning protrusions evenly distributed circumferentially on the end face of the second connector, and a target that mates with the laser emitters and a positioning hole that mates with the positioning protrusions provided on the mating end face of the glove box.

[0006] Furthermore, the first connector has a sealing ring groove embedded in its end, and a sealing ring is provided in the sealing ring groove. One end of the second connector has a sealing ring platform that engages with the sealing ring groove and abuts against the sealing ring. The other end of the second connector has several rotary torsion locks evenly distributed around its outer circumference for locking the second connector and the glove box.

[0007] Furthermore, the rotary torsion lock includes a knob seat and a locking rod connected to each other. The knob seat is rotatably connected to the second connector, and the end of the knob seat is in limiting contact with the second connector. The locking rod is radially provided with a support rod. A locking hole is provided on the mating end face of the glove box. The locking hole is a stepped cylindrical hole with a larger inner diameter and a smaller outer diameter. A positioning notch is provided on the mating end face of the glove box that communicates with the locking hole for fitting through the support rod.

[0008] Furthermore, the push-pull rod has a multi-fold structure, which includes a telescopic section, a folding section, and a connecting section that connects to the sample chamber. The telescopic section includes several telescopic joints that slide and nest in sequence. Between adjacent telescopic joints, a spring positioning pin is provided in the inner telescopic joint to fix the adjacent telescopic joints, and a positioning hole is provided on the side wall of the outer telescopic joint to cooperate with the spring positioning pin.

[0009] Furthermore, the two ends of the folding segment are respectively hinged to the connecting segment and the telescopic joint nested on the outermost side. The hinged end of the connecting segment is provided with a first guide groove for guiding the folding segment to rotate vertically in an oriented manner, and the hinged end of the telescopic joint nested on the outermost side is provided with a second guide groove for guiding the telescopic segment to rotate vertically in an oriented manner.

[0010] Furthermore, after the folding section and telescopic section are flipped over, the push-pull rod is U-shaped, and the transfer vehicle is equipped with a clamp for clamping and fixing the telescopic section.

[0011] Furthermore, the end of the telescopic joint nested on the innermost side is connected to a holding seat, and a reference rod extends radially from the holding seat. The horizontal arrangement of the reference rod corresponds to the horizontal upward orientation of the sample chamber opening.

[0012] Furthermore, the transfer vehicle is equipped with a main slide rail and side slide rails arranged parallel to both sides of the main slide rail, and a slide seat is provided below the lead tank that is slidably connected to the main slide rail and the side slide rails.

[0013] Furthermore, the transfer vehicle is adjustablely connected to a positioning block that abuts against the slide to limit the extension of the lead can.

[0014] Furthermore, the shielding cavity is truncated cone-shaped with a larger front end and a smaller rear end, and the sample chamber has a receiving groove shaped like a semi-cylindrical funnel with a larger front end and a smaller rear end.

[0015] The present invention has at least the following advantages and beneficial effects:

[0016] (1) The device can be adapted to various glove box flange interfaces with replaceable second connectors without overall modification, thus improving the adaptability of the device. The optical alignment of the laser emitter and the target, combined with the mechanical positioning of the positioning protrusion and the positioning hole, reduces the difficulty of aligning the lead can and the glove box and improves the docking efficiency.

[0017] (2) By setting a lead sealing ring groove at the end of the first connector and embedding a sealing ring therein, and cooperating with the sealing ring platform set at the second connector, a double seal is achieved for the connector connection. The second connector and glove box are locked by rotating a torsion lock, which can achieve both quick operation and reliable locking force.

[0018] (3) The multi-segment retraction and directional folding storage design of the push-pull rod is adapted to the sample inlet channel of different depths of the glove box, preventing the sample chamber from colliding due to the shaking of the push-pull rod during transportation.

Detailed Implementation

[0026] The specific implementation method is described below with reference to the accompanying drawings.

[0027] Example

[0028] like Figures 1 to 6As shown, this embodiment mainly discloses a movable high-powered radioactive sample transport lead container 2 suitable for LOCA shielded glove box. Its main structure includes: 1. A movable high-powered radioactive sample transport lead container 2 suitable for LOCA shielded glove box, including a transport vehicle 1, a lead container 2 horizontally slidably connected to the transport vehicle 1, a shielding cavity 20 provided inside the lead container 2, a push-pull rod 3 axially movably connected to the rear end of the lead container 2, a sample chamber 4 for loading high-powered radioactive samples provided at one end of the push-pull rod 3 inside the shielding cavity 20, a first connector 5 connected to the front end of the lead container 2, a second connector 6 for mating with the glove box detachably connected to the end of the first connector 5, a shielding valve 51 provided inside the first connector 5, a plurality of laser emitters 61 arranged circumferentially on the outer side of the second connector 6, a plurality of positioning protrusions 62 evenly distributed circumferentially on the end face of the second connector 6, and a target that mates with the laser emitters 61 and a positioning hole 312 that mates with the positioning protrusions 62 provided on the mating end face of the glove box. Specifically, the transport vehicle 1, serving as the foundation for carrying and transporting the lead container 2, can utilize an existing structure. Its overall design is a trolley structure with lockable casters and height-adjustable support feet, including a support frame. The support feet are located at the four corners of the lower end of the support frame, used to adjust the height of the upper platform of the transport vehicle 1, ensuring the lead container 2 is horizontally aligned with the glove box interface, and also serving to support and fix the carrier, preventing swaying during docking. The casters are located on the crossbeam at the lower end of the support frame, used to propel the carrier to achieve short-distance cross-regional movement. Once at the target position, they lock to prevent slippage, ensuring stability during docking and sample loading / unloading. The lead container 2 is made of lead, utilizing lead's radiation shielding properties to enclose the high-radiation sample for radiation isolation. An internal shielding cavity 20 is provided to contain the high-radiation sample, preventing radiation leakage from the sample from harming personnel and the environment. A push-pull rod 3 is axially movable through the rear end of the lead container 2, driving the sample chamber 4 in and out of the shielding cavity 20. The first connector 5 is detachably connected to the front end of the lead container 2 via bolts, providing a connection base for the first connector 5. Simultaneously, a shielding valve 51 (preferably a ball valve) is installed inside the first connector 5. The actuator of the shielding valve 51 is external to the first connector 5. After the forced discharge sample is inserted, rotating the actuator closes the shielding valve 51, sealing the shielding cavity 20 to prevent radiation leakage. The second connector 6 is used to adapt to different specifications of glove box flange interfaces, improving the adaptability of the device and allowing the lead container 2 to be adapted to various glove boxes without overall modification. The laser emitter 61 can adopt existing technology, circumferentially arranged outside the second connector 6. Three emitters can be installed, using a 650nm low-power red laser to avoid additional radiation risks. The corresponding target has a crosshair at its center, which, in conjunction with the laser emitter 61, achieves optical alignment for preliminary alignment guidance between the lead container 2 and the glove box over a long distance. Meanwhile, the positioning protrusion 62 is made of lead and has a conical structure (head taper 30°); correspondingly, the positioning hole 312 is trumpet-shaped with a smooth slope on its inner wall. Through the mechanical cooperation between the positioning protrusion 62 and the positioning hole 312, close-range precise correction is achieved. The dual guidance reduces the difficulty of manual alignment, avoids collision damage between the second connector 6 and the glove box, and improves docking efficiency.

[0029] Furthermore, in specific implementation, the first connector 5 provided in the embodiment of the present invention has a sealing ring groove embedded in its end, and a sealing ring is provided in the sealing ring groove. One end of the second connector 6 has a sealing ring platform that engages with the sealing ring groove and abuts against the sealing ring. The other end of the second connector 6 has several rotary torsion locks 63 evenly distributed around its outer circumference for locking the second connector 6 and the glove box. Specifically, the overall structure of the second connector 6 is two flange structures connected by a connecting cylinder. One flange is connected to the first connector 5, and the other flange is connected to the glove box. The sealing ring groove is a lead annular groove, which matches the shielding performance of the lead container 2. The sealing ring provided in the groove is a radiation-resistant O-ring, which is suitable for long-term use in a strong radiation environment and prevents radiation leakage through the gap. The sealing ring platform at one end of the second connector 6 is precisely matched with the sealing ring groove in size and is made of lead to ensure shielding continuity. It can be engaged in the sealing ring groove and abut against the sealing ring to achieve a sealed connection between the first connector 5 and the second connector 6, realizing a double seal (physical seal + radiation shielding seal) for the connector connection. The second connector 6 has four circumferentially evenly distributed rotary torsion locks 63 (preferably four, radially symmetrically distributed to ensure uniform locking force) on the outer side of the other end. These locks are used to quickly lock the glove box docking end without tools, which greatly shortens the docking operation time and improves the operation efficiency. The circumferentially evenly distributed structure ensures the stability after locking and prevents the docking from loosening.

[0030] Furthermore, in a specific implementation, the rotary torsion lock 63 provided in this embodiment of the invention includes a knob seat 631 and a locking rod 632 connected to each other. The knob seat 631 is rotatably connected to the second connector 6, and the end of the knob seat 631 is limited and abutted against the second connector 6 to prevent axial movement. The locking rod 632 is radially provided with a support rod 633, and a locking hole is opened on the glove box mating end face. The locking hole is a stepped cylindrical hole with a larger inner diameter and a smaller outer diameter, and a positioning notch communicating with the locking hole for mating with the support rod 633 is opened on the glove box mating end face. Specifically, one end of the locking rod 632 is connected to the knob seat 631, and the other end passes axially through the second connector 6. The larger inner hole of the locking hole provides rotation space for the support rod 633, and the smaller outer hole forms an axial limit for the locking rod 632. When the support rod 633 enters the larger inner hole of the locking hole through the positioning notch, it can be rotated 90° to form an axial lock with the stepped surface, which can achieve both quick operation and reliable locking force. It should be noted that the distance between the support rod 633 and the knob seat 631 is exactly the sum of the axial length of the outer small hole of the lock hole and the thickness of the flange of the second connector 6 used for docking the glove box, ensuring the reliability of the docking.

[0031] Furthermore, in a specific implementation, the push-pull rod 3 provided in the embodiments of the present invention has a multi-fold structure. The push-pull rod 3 sequentially includes a telescopic section 31, a folding section 32, and a connecting section 33 connected to the sample chamber 4. The telescopic section 31 includes several telescopic joints 310 that are slidably nested in sequence. Between adjacent telescopic joints 310, a spring positioning pin 311 for fixing the adjacent telescopic joints 310 is provided in the inner telescopic joint 310, and a positioning hole 312 that cooperates with the spring positioning pin 311 is opened on the side wall of the outer telescopic joint 310. Specifically, the outer diameter of the telescopic joints 310 of the telescopic section 31 decreases sequentially from the outside to the inside to ensure smooth sliding nesting. A wear-resistant coating (such as nitriding treatment to reduce sliding wear) is provided between adjacent telescopic joints 310; the spring positioning pin 311 can adopt existing technology, including a fixed sleeve and a telescopic cylinder, with a spring provided between the fixed sleeve and the telescopic cylinder. The end of the telescopic cylinder is hemispherical, which facilitates insertion / extraction into the positioning hole 312 and reduces jamming. Taking two adjacent telescopic sections 310 as an example, a spring positioning pin 311 is provided at the end of the inner telescopic section 310 near the outer telescopic section 310; a positioning hole 312 is provided at the end of the outer telescopic section 310 near the inner telescopic section 310, and a shallow groove is provided on the inner wall of the other end of the outer telescopic section 310 to cooperate with the telescopic cylinder for limiting the spring positioning pin 311 after retraction. When the telescopic section 31 needs to be extended, the inner telescopic section 310 only needs to be pulled outward with force to disengage the spring positioning pin 311 from the shallow groove until the telescopic cylinder of the spring positioning pin 311 is engaged in the positioning hole 312 to fix the length.

[0032] Furthermore, in a specific implementation, the two ends of the folding segment 32 provided in this embodiment of the invention are respectively hinged to the connecting segment 33 and the outermost telescopic joint 310. The hinged end of the connecting segment 33 is provided with a first guide groove 331 for guiding the folding segment 32 to rotate vertically, and the hinged end of the outermost telescopic joint 310 is provided with a second guide groove 313 for guiding the telescopic segment 31 to rotate vertically. Specifically, the hinged end of the connecting segment 33 is formed by beveling through machining to form the first guide groove 331, and the hinged end of the outermost telescopic joint 310 is formed by beveling through machining to form the second guide groove 313. The two ends of the folding segment 32 are respectively fitted into the connecting segment 33 and the outermost telescopic joint 310. Taking the folding segment 32 and the connecting segment 33 for folding and folding as an example, when the folding segment 32 attempts to rotate in a non-preset direction (reverse direction), the extended portion at the end of the folding segment 32 will tightly abut against the inner wall of the connecting segment 33, forming a rigid limit. The spatial shape of the first guide groove 331 is perfectly matched with the forward flipping trajectory of the folding section 32. On the one hand, the groove provides sufficient clearance for the forward flipping of the folding section 32, avoiding structural interference; on the other hand, the inclination angle of the groove wall guides the folding section 32 to turn precisely along the preset trajectory. When the folding section 32 flips forward to a 90° vertical state, the end of the first guide groove 331 (arc-shaped limiting surface) abuts against the outer wall of the folding section 32, forming a rigid stop, restricting its further flipping, thereby achieving triple control of "reverse locking - forward guidance - end point limiting".

[0033] Furthermore, in specific implementation, after the folding section 32 and telescopic section 31 provided in the embodiments of the present invention are flipped, the push-pull rod 3 is U-shaped, and the transport vehicle 1 is provided with a clamp for clamping and fixing the telescopic section 31. Specifically, after the folding section 32 and the telescopic section 31 are bent, the U-shaped opening of the push-pull rod 3 faces the glove box, and the telescopic section 31 is folded and stored under the platform on the upper part of the transport vehicle 1 and fixed by the clamp, saving the lateral storage space of the push-pull rod 3 and avoiding the risk of collision of the sample chamber 4, sample damage or radiation leakage caused by the push-pull rod 3 due to bumps and shaking during transportation.

[0034] Furthermore, in a specific implementation, the innermost telescopic joint 310 provided in this embodiment of the invention is connected to a handle 314 at its end. A reference rod 315 extends radially from the handle 314, and the horizontal arrangement of the reference rod 315 corresponds to the sample chamber 4 opening being horizontally upwards. Through the rigid linkage between the reference rod 315 and the sample chamber 4, the operator does not need to approach the lead container 2; they can determine the orientation of the sample chamber 4 opening simply by observing whether the reference rod 315 is horizontal. This avoids sample loading deviations or sample drops due to misjudgment. When unloading the sample, simply rotating the reference rod 315 180° allows the sample to be poured out.

[0035] Furthermore, in a specific implementation, the transfer vehicle 1 provided in this embodiment of the invention is equipped with a main slide rail 11 and side slide rails 12 arranged parallel to both sides of the main slide rail 11. A slide block 21, slidably connected to the main slide rail 11 and the side slide rails 12, is provided below the lead can 2. Specifically, the main slide rail 11 is located directly below the lead can 2, bearing the weight of the lead can 2. A polytetrafluoroethylene slider is embedded in the surface of the main slide rail 11 to reduce sliding resistance and facilitate the horizontal pushing of the lead can 2. The side slide rails 12 restrict the lateral displacement of the lead can 2 and eliminate gap errors through mechanical guidance.

[0036] Furthermore, in specific implementation, the transfer vehicle 1 provided in this embodiment of the invention is adjustablely connected to a positioning block 13 that abuts against the slide 21 to limit the extension of the lead can 2. Specifically, a strip groove parallel to the main slide rail 11 is provided on the platform of the transfer vehicle 1, and the positioning block 13 is connected to the strip groove by bolts. Before the first docking, the precise distance between the glove box interface and the transfer vehicle 1 is measured, the positioning block 13 is adjusted to the corresponding position, and tightened with screws. This reduces repeated adjustments for manual alignment and improves docking efficiency.

[0037] Furthermore, in specific implementation, the shielding cavity 20 provided in the embodiment of the present invention is a frustoconical shape with a large front end and a small rear end, which facilitates the loading and unloading of the strong-release sample; the sample chamber 4 is provided with a receiving groove with a large front end and a small rear end in the shape of a semi-cylindrical funnel, which facilitates the loading and unloading of the strong-release sample, especially the loading and unloading of the strong-release sample after explosion.
