Description

Technical Field

[0001] This invention relates to the field of radiation protection technology, and more specifically to a movable lead-frame folding shielding wall structure for industrial radiation protection. Background Technology

[0002] Industrial radiation is mainly generated by industrial flaw detection equipment bombarding a target material with high-voltage accelerated electrons, producing X-rays, or by the decay of radioactive isotopes such as cobalt-60 and iridium-192 releasing gamma rays. Its ionizing radiation has strong penetrating power and can cause irreversible damage to the human body, such as hematopoiesis and reproduction. Protective lead rooms use lead as the core shielding material, which can effectively attenuate and block radiation leakage, control the radiation dose within the national safety limits, protect the health of workers and the surrounding public, meet radiation safety regulations, achieve safe isolation of flaw detection operations, prevent environmental risks, and ensure the compliant and efficient conduct of industrial non-destructive testing.

[0003] Referring to the relevant patent CN110632102A, the essence of the technology is to divide the enclosure into three independently arranged areas: an electrical equipment room, a testing room, and a control room. In the testing room, differential thickness lead plates and double-layer lead plate structures are used to achieve precise and efficient radiation shielding. The top is equipped with an openable and movable top plate with a waterproof sealing structure, which ensures the airtightness of the enclosure without compromising radiation protection capabilities. The bottom frame integrates ventilation ducts and wiring channels, and can be used in both hoisting and grounding and vehicle-mounted applications. It is also equipped with hoisting, lighting, monitoring, emergency stop and other operational safety structures, ultimately realizing the integration of mobility, portability, reliable shielding, sealing and insulation and safe operation for low-energy X-ray industrial CT operations.

[0004] Currently, industrial radiation protection mainly adopts two methods: fixed lead rooms or temporary simple shielding facilities. Fixed lead rooms cannot be moved and can only be used in fixed locations. They have poor adaptability, are bulky, and are inconvenient to transport and install, failing to meet the protection needs of outdoor and temporary work scenarios. Temporary simple shielding facilities are cumbersome to assemble, require tools, are time-consuming and labor-intensive, and are prone to gaps at the joints that can lead to radiation leakage. They also have insufficient protection strength, cannot dynamically adjust the protection level according to the radiation intensity at the site, have unstable support structures that are prone to tipping over, and occupy a lot of space when stored and transported, making them difficult to adapt to work sites of different shapes and sizes.

[0005] Therefore, it is essential to provide a movable lead-frame foldable shielding wall structure for industrial radiation protection. This structure features modular design for tool-free rapid assembly, a foldable structure for easy transport and storage, adjustable protection strength components to adapt to different radiation scenarios, optimized sealing structure at joints to eliminate radiation leakage risks, and a stable support mechanism to improve structural reliability. This improved approach offers flexible adaptation to various work sites, convenient deployment, and high-efficiency protection, thus addressing the aforementioned issues. Summary of the Invention

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1: As Figure 1-10 As shown, the present invention provides a movable lead room foldable shielding wall structure for industrial radiation protection, including a connecting sleeve 1. The connecting sleeve 1 is provided with a connecting component 4 for modular connection. The side of the connecting sleeve 1 is provided with a protective component 2 that can adjust the thickness of the shielding wall according to the requirements. The side of the protective component 2 is provided with an adjusting component 3 that can adjust the assembly angle. The connecting component 4 includes a connecting sleeve 41 provided inside the connecting sleeve 1, a movable seat 42 slidably installed inside the connecting sleeve 41, and a limiting rod 43 fixedly installed on the top surface of the movable seat 42 and penetrating the top surface of the connecting sleeve 41 for connecting adjacent connecting sleeves 1. There are two movable seats 42, which are arranged opposite to each other at both ends inside the connecting sleeve 41. The connecting sleeve 41 is provided with two springs 44. One end of the spring 44 is installed on the bottom surface of the movable seat 42. The limiting rod 43 is movably installed inside the connecting sleeve 1.

[0035] The equipment is made of a built-in lead plate covered with an outer isolation layer. The radiation protection properties of lead, combined with the outer isolation layer, achieve anti-oxidation, anti-scratch, and structural reinforcement of the lead plate, thereby enhancing the overall protective strength of the equipment. The connecting component 4 is set on the side of the basic shielding wall 21, respectively set on its top and bottom. The protective component 2 and the connecting sleeve 1 form a basic component. There are two of these components, which are set opposite to each other on the left and right sides of the adjusting component 3, forming a modular component. Each modular component is connected by the connecting component 4, and the corrugated protective sleeve 34 set inside the adjusting component 3 ensures the shielding effect between each module, eliminates the linear gaps at the module splicing, and prevents radiation from escaping in a straight line along the gaps.

[0036] The two movable seats 42 inside the connecting component 4 are arranged opposite each other. One end of the movable seat 42 passes through the side of the connecting sleeve 41. The corresponding position of the connecting sleeve 41 is provided with a groove to ensure that one end of the movable seat 42 can slide inside it. At the same time, it ensures that the overall thickness of the connecting component 4 is flush with the thickness of the protective component 2, preventing the formation of radiation scattering dead angles due to thickness difference, and ensuring the continuity and uniformity of the protective surface. The two springs 44 inside the connecting sleeve 41 can ensure that the limiting rod 43 is always in the extended state and rotates inside the connecting sleeve 1 to adjust the connection angle of the two adjacent protective components 2, so as to realize the flexible construction of any polygonal shielding area and adapt to different shapes of work sites.

[0037] The protective component 2 includes a base shielding wall 21 fixedly installed on the side of the connecting sleeve 1, a pre-embedded lead plate 26 fixedly installed inside the base shielding wall 21 to provide base shielding function, lead plate slot housings 22 fixedly installed on both sides of the base shielding wall 21 for modular assembly and disassembly, and a rotating shaft 24 fixedly installed on the other side of the base shielding wall 21 for connection. There are two lead plate slot housings 22, which are fixedly installed on the left and right ends of the base shielding wall 21 respectively. Multiple insert lead plates 23 are movably installed inside the lead plate slot housings 22. A limit plate 25 is fixedly connected to the top surface of the rotating shaft 24.

[0038] The protective component 2 is based on the basic shielding wall 21. Multiple pre-embedded lead plates 26 are fixedly connected inside the basic shielding wall 21. Each pre-embedded lead plate 26 is connected by a combination of conical protrusions and conical grooves to ensure the stability of the connection and the sealing of the gaps. The straight splicing gaps are transformed into tortuous labyrinthine channels, which greatly increases the radiation penetration path length. By utilizing the characteristic that the radiation intensity decreases exponentially with the penetration distance, the gap leakage rate is significantly reduced. Lead plate slot housings 22 are provided on both sides of the basic shielding wall 21. Inserted lead plates 23 can be filled inside the lead plate slot housings 22 to enhance the shielding strength of the protective component 2. The inserted lead plates 23 have a similar structure to the pre-embedded lead plates 26, but are oriented differently to ensure the sealing of the shield. The orthogonally arranged lead plate layers simultaneously block direct and scattered radiation from different directions, forming a three-dimensional protective barrier.

[0039] The top surface of the rotating shaft 24 is provided with two positioning holes with an included angle of 90 degrees. The bottom surface of the rotating shaft 24 is provided with a limiting plate 25. The two sides of the limiting plate 25 are provided with two positioning grooves. The positioning holes and positioning grooves are respectively adapted to the angle limiting rod 311 and the spring locking rod 314 to form a double mechanical locking mechanism to prevent the protective component 2 from being offset by external force collision and to ensure the accuracy of the protective boundary.

[0040] In this embodiment, by folding the two opposing protective components 2 on both sides of the adjusting component 3, the lead plate slot housing 22 is not provided with an inserted lead plate 23, and the connecting component 4 is not installed inside the connecting sleeve 1. At this time, the mass of a single component is low, and it can be transported to the required outdoor industrial radiation area. The protective components 2 on both sides are unfolded with the adjusting component 3 as the axis. Furthermore, by pressing the two movable seats 42, the limiting rod 43 is retracted into the connecting sleeve 41. After the connecting sleeve 41 is installed inside the connecting sleeve 1, the limiting rod 43 is released so that it is locked inside the connecting sleeve 1, ensuring that the connecting component 4 can connect two adjacent components, so that it can quickly form a protective shielding area in the required area, avoiding the industrial radiation from affecting non-target areas, realizing tool-free rapid assembly, and greatly shortening the on-site protection preparation time.

[0041] When a complete fixed shielding area is formed by the cooperation of the connecting sleeve 1, protective component 2, adjusting component 3, and connecting assembly 4, if the radiation intensity of the current area exceeds the protection strength of the pre-embedded lead plate 26 set inside the basic shielding wall 21, insert lead plates 23 can be inserted into the lead plate slot housing 22 on both sides. Since the inserted lead plates 23 and the pre-embedded lead plates 26 face opposite directions, the thickness of the shielding is increased by the spaced insert lead plates 23 and the pre-embedded lead plates 26. At the same time, the individual insert lead plates 23 and the pre-embedded lead plates 26 form a labyrinthine gap with conical protrusions and conical grooves, which prevents radiation from escaping from the gap, enhances the overall protection strength of the equipment, forms an orthogonal superimposed protection system, and improves protection efficiency.

[0042] Example 2: Figure 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the adjusting component 3 includes a connecting base 31 disposed on the side of the rotating shaft 24, a support rod 32 movably installed on the back of the connecting base 31 for support, an auxiliary support rod 37 movably installed inside the connecting base 31 for auxiliary support, a corrugated protective sleeve 34 disposed on the side of the connecting base 31 for enhancing the gap shielding effect, a connecting buckle 315 fixedly installed on the other side of the connecting base 31 for connection, and a spring clip 314 disposed on the bottom surface of the connecting base 31 for positioning. Connecting seats 38 are provided at both ends of the side of the connecting base 31. The number of protective components 2 is two. The two protective components 2 are rotatably connected to the inside of the connecting seats 38 through the rotating shaft 24. An angle limiting rod 311 is threadedly connected inside the top surface of the connecting base 31, and the angle limiting rod 311 penetrates the top surface of the connecting base 31.

[0043] Two connecting seats 38 are provided on the side of the connecting base 31. The connecting seats 38 cooperate with the rotating shaft 24 to ensure that the protective component 2 can move while connected to the adjusting component 3. One end of the rotating shaft 24 passes through the bottom surface of the connecting seat 38 and is fixedly connected to the limiting plate 25. The limiting plate 25 rotates on the bottom surface of the connecting seat 38 and is always in contact with the spring latch 314. The spring latch 314 is engaged in the slot on the side of the limiting plate 25 to limit the unfolding angle of the protective component 2. The angle limiting rod 311 provided on the top surface of the connecting seat 38 can be engaged in the inside of the rotating shaft 24 to cooperate with the spring latch 314 to further limit the unfolding angle of the protective component 2. The automatic pre-tightened spring latch achieves rapid initial positioning, and the rigid angle limiting rod achieves final locking, taking into account both ease of operation and structural reliability.

[0044] The lower end of the angle limiting rod 311 is engaged inside the top surface of the rotating shaft 24, one end of the spring rod 314 is engaged on the side of the limiting plate 25, the side of the connecting base 31 is provided with a first fixing groove 313, the side of the connecting base 31 and the side of the first fixing groove 313 is provided with a second fixing groove 316, the side of the corrugated protective sleeve 34 is fixedly connected with a limiting buckle 35, the limiting buckle 35 is engaged inside the second fixing groove 316, the inside of the first fixing groove 313 is engaged with a fixing buckle 310, and the side of the fixing buckle 310 is fixedly connected with a movable shielding cover 39.

[0045] The corrugated protective sleeve 34 is made entirely of lead powder, which, while ensuring its flexibility, also provides a certain level of radiation protection. The lead powder particles, evenly dispersed in the rubber matrix, absorb radiation energy while retaining the elasticity and extensibility of the rubber, achieving a flexible seal for irregular gaps. The corrugated protective sleeve 34 has opposing limiting buckles 35 at both ends, which can be engaged inside the second fixing groove 316 to connect two connected components.

[0046] The bottom surface of the support rod 32 is movably connected to a telescopic support foot 33, and the top surface of the telescopic support foot 33 is fixedly connected to an angle limiting slide plate 312. The angle limiting slide plate 312 is slidably connected inside the bottom surface of the support rod 32. The inside of the support rod 32 is rotatably connected to a threaded adjusting rod 36. One end of the telescopic support foot 33 is threadedly connected to the outer surface of the threaded adjusting rod 36. One end of the surface of the auxiliary support rod 37 is movably connected to a movable sleeve 320. One end of the auxiliary support rod 37 is movably connected to the side of the support rod 32. The side of the movable sleeve 320 is fixedly connected to an angle locking slide plate 317. The angle locking slide plate 317 is slidably connected inside the support rod 32. The bottom surface of the movable sleeve 320 is fixedly connected to a buckle 318. The inside of the connecting base 31 is slidably connected to a movable buckle 319. The side of the movable buckle 319 is provided with a return spring 321. The return spring 321 is provided inside the connecting base 31. The buckle 318 is snapped into the side of the movable buckle 319.

[0047] A support rod 32 is provided on the back of the connecting base 31 and fixed inside it by a pivot. A telescopic support foot 33 is provided on the bottom surface of the support rod 32. The telescopic support foot 33 is limited by an angle limiting slide plate 312 so that it can only slide along the support rod 32. A threaded adjustment rod 36 is provided inside the support rod 32 to control the extension length of the telescopic support foot 33, further adapting to the support needs of different ground heights. A groove is provided inside the connecting base 31, which can be used to snap one end of the telescopic support foot 33 into the groove, ensuring that the support rod 32 can be retracted on the back of the connecting base 31 and remain relatively flat, which facilitates the folding, storage and stacking of the equipment for transportation, and reduces the storage space occupied.

[0048] The connecting base 31 is equipped with a movable buckle 319 that can slide left and right. One end of the movable buckle 319 passes through the interior of the connecting base 31. It can be moved to further release the restriction on the buckle 318. The side of the movable buckle 319 is equipped with a locking block that matches the buckle 318. The return spring 321 can ensure that the buckle 318 and the movable buckle 319 are always in the locked state. The fixed buckle 310 is restricted by the angle locking slide plate 317 to move only in a straight line along the internal slide groove of the foundation shielding wall 21. The locking of the buckle 318 and the movable buckle 319 can restrict the position of the current movable sleeve 320. The auxiliary support rod 37 is movably connected to the support rod 32. When the support rod 32 moves, the movable sleeve 320 can be moved by the auxiliary support rod 37, realizing automatic locking after the support rod is unfolded. No additional tools are required, which improves the efficiency of on-site deployment.

[0049] There are two types of connecting bases 31, which have the same basic structure. The difference is that the other connecting base 31 has a sleeve on its side that is compatible with the connecting buckle 315. The two oppositely arranged connecting bases 31 are connected and secured by the connecting buckle 315 and the sleeve. The movable shielding cover 39 is made of the same material as the corrugated protective sleeve 34 and is snapped into the inside of the first fixing groove 313 by the fixing buckle 310. It is used to cover the splicing gap between the connecting bases and achieve full protection without dead angle shielding.

[0050] In this embodiment, after the adjusting member 3 is placed in the desired position, the threaded adjusting rod 36 can be rotated in the opposite direction to drive the telescopic support foot 33 to move, thereby releasing the restriction on the support rod 32. At this time, the support rod 32 is pushed outward, and the threaded adjusting rod 36 is rotated further until the telescopic support foot 33 contacts the ground. At this time, the bottom surface of the protective member 2 and the telescopic support foot 33 form a triangular support structure to ensure its stability during support. By utilizing the geometric invariance of the triangular structure, the overturning resistance of the equipment is improved.

[0051] As the support rod 32 unfolds, it drives the auxiliary support rod 37 to move, which in turn drives the movable sleeve 320 to slide down along the angle locking slide plate 317 until the buckle 318 engages with the side of the movable buckle 319, thus limiting the position of the support rod 32. At this point, the connecting base 31, the auxiliary support rod 37, and the support rod 32 together form another triangular support structure, ensuring the stability of the support rod 32 when it is supported, forming a double triangular stability system, which greatly improves the overall rigidity and load-bearing capacity of the support structure.

[0052] After the protective component 2 is unfolded to 90 degrees, the spring lever 314 will engage with the side of the limiting plate 25 to initially limit the unfolding angle of the protective component 2. Further limiting of the protective component 2 is achieved by installing the angle limiting rod 311 on the top surface of the rotating shaft 24. The unfolding angle of the protective component 2 and the angle between two adjacent protective components 2 connected by the connecting component 4 can be selected to adapt the shielding area to the current working area. At this time, the adjustment component 3 inside the shielding area, which is composed of multiple connecting components 4, works together to further ensure the stability of the shielding area. Through multi-point support and multi-module collaboration, a rigid protective frame with overall force is formed.

[0053] After the equipment shielding area is defined, the compressed corrugated protective sleeve 34 is engaged with the second fixing groove 316 through the limiting buckle 35. At this time, the corrugated protective sleeve 34 covers the surface of the protective component 2 and slides along the surface of the adjusting component 3 until it covers the two adjacent protective components 2 and the connecting sleeve 1, thereby reinforcing the gap at the component connection. Another limiting buckle 35 is engaged with the second fixing groove 316 to limit the corrugated protective sleeve 34, further ensuring the shielding strength of the current shielding area, effectively sealing the weak links at the module splicing point, and eliminating the risk of radiation leakage.

[0054] Fold the two protective components 2 onto the side of the adjusting component 3, while ensuring that the support rod 32 on the side of the adjusting component 3 provides sufficient support strength. At this time, the connecting buckle 315 in this state can be installed inside the sleeve on the side of the connecting base 31. Through the cooperation of the fixing buckle 310 and the movable shielding cover 39, the shielding strength between the two connecting bases 31 is reinforced. Furthermore, the two adjacent sets of structures are connected by two connecting components 4 to cooperate with the original shielding area and further divide the shielding strength area. At this time, the two folded protective components 2 can further enhance the shielding strength of the area for the protection of strong radiation equipment, forming a double-layer orthogonal lead plate protection structure and improving the protection level of the area.

[0055] The working principle of this movable lead-frame folding shielding wall structure used for industrial radiation protection will be explained in detail below.

[0056] like Figure 1-10 As shown, the two opposing protective components 2 can be folded and stored on both sides of the adjusting component 3. At this time, the lead plate slot housing 22 is not installed with the inserted lead plate 23, and the connecting component 4 is not installed in the connecting sleeve 1. The weight of a single module component is greatly reduced, making it easy to manually transport to the outdoor industrial radiation operation site.

[0057] After placing the adjusting component 3 in the predetermined position, rotate the threaded adjusting rod 36 in the reverse direction to retract the telescopic support foot 33, releasing the lock on the support rod 32; push the support rod 32 outward to the extended state, and then rotate the threaded adjusting rod 36 in the forward direction to extend the telescopic support foot 33 and make it firmly contact the ground. At this time, the bottom surface of the protective component 2 and the telescopic support foot 33 form a triangular support structure, which utilizes the geometric invariance of triangles to improve the equipment's anti-overturning ability.

[0058] As the support rod 32 unfolds, it drives the auxiliary support rod 37 to move, which in turn causes the movable sleeve 320 to slide down along the angle locking slide plate 317 until the buckle 318 automatically engages with the side of the movable buckle 319, completing the automatic locking of the support rod 32. At this time, the connecting base 31, the auxiliary support rod 37, and the support rod 32 form a second triangular support structure, creating a double triangular stability system, which greatly improves the overall rigidity and load-bearing capacity of the support structure.

[0059] The protective components 2 on both sides are unfolded with the adjusting component 3 as the axis. When unfolded to 90°, the spring latch 314 automatically engages with the positioning groove on the side of the limiting plate 25, completing the initial limiting of the unfolding angle; then the angle limiting rod 311 is inserted into the corresponding positioning hole on the top surface of the rotating shaft 24 to achieve double angle locking. By selecting different positioning holes and adjusting the connection angle of the connecting component 4, the shielding area can be completely adapted to the shape and size of the work site.

[0060] Pressing the two movable seats 42 of the connecting component 4 causes the limiting rod 43 to retract into the connecting sleeve 41; after inserting the connecting sleeve 41 into the corresponding hole of the connecting sleeve 1, releasing the movable seats 42 causes the limiting rod 43 to pop out under the action of spring force and lock into the inner wall of the connecting sleeve 1, completing the quick connection of two adjacent modular components. Multiple modular components are sequentially spliced ​​together through the connecting component 4, and with the multi-point support of each adjusting component 3, a rigid protective frame bearing the overall force is formed, realizing tool-free rapid assembly and significantly shortening the on-site protection preparation time;

[0061] After the overall frame of the shielding area is built, the corrugated protective sleeve 34 in a compressed state is snapped into the second fixing groove 316 of a connecting base 31 by the limiting buckle 35 at one end; the corrugated protective sleeve 34 is stretched so that it completely covers the splicing gap between the two adjacent protective components 2 and the connecting sleeve 1, and then the limiting buckle 35 at the other end is snapped into the second fixing groove 316 of the corresponding connecting base 31, effectively sealing the weak link at the splicing of the module and eliminating the hidden danger of radiation leakage;

[0062] After the basic shielding area is built, if the on-site radiation intensity exceeds the protective capacity of the lead plate 26 embedded in the basic shielding wall 21, insert lead plates 23 can be inserted into the lead plate slot housings 22 on both sides. Since the insert lead plates 23 and the embedded lead plates 26 face opposite directions, they are arranged at intervals to form an orthogonal superimposed protection system. At the same time, the conical concave-convex structure forms a three-dimensional labyrinth-like gap, which greatly increases the radiation penetration path length and significantly improves the overall protection strength.

[0063] For work areas with high radiation intensity, the two protective components 2 can be folded and stored on the side of the adjusting component 3 to ensure that the support rod 32 of the adjusting component 3 provides sufficient support; the connecting buckle 315 is installed in the sleeve on the side of the two oppositely arranged connecting bases 31 to realize the back-to-back connection of the two module components; the movable shielding cover 39 is snapped into the first fixing groove 313 by the fixing buckle 310 to strengthen the shielding strength between the connecting bases.

[0064] The enhancement module is connected to the original shielding area via connecting component 4, allowing for the creation of areas with higher protection levels. In its folded state, the two protective components 2 form a double-layer orthogonal lead plate protection structure, significantly improving the protection level and meeting the protection requirements of high-radiation equipment.

[0065] In summary, the essence of the technology is to achieve modular, foldable, tool-free, and rapid construction of an industrial radiation shielding area through the cooperation of protective component 2, adjusting component 3, connecting component 4, connecting sleeve 1, and other components. It simultaneously provides basic radiation protection and stable support. Furthermore, through the orthogonal superposition of inserted lead plate 23 and pre-embedded lead plate 26, the gap reinforcement of corrugated protective sleeve 34, and the linkage of double triangular support and double angle locking mechanism, further progress is made in dynamically adapting to different radiation intensities, eliminating radiation leakage from splicing gaps, and significantly improving the overall structural rigidity and protection reliability.

Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
