Description

Technical Field

[0001] This invention relates to the field of radiation protection technology, and more specifically to a lead-free radiation shielding partition wall. Background Technology

[0002] In radiation protection in the medical, nuclear industry, and scientific research fields, traditional partitions mainly use lead plates. Lead plates have drawbacks such as high toxicity, high weight, difficulty in processing and shaping, and environmental unfriendliness. In recent years, lead-free protective materials (such as polymer composites containing tungsten, bismuth, and barium sulfate) have gradually become the trend, as they are more environmentally friendly and easier to process.

[0003] However, existing lead-free protective walls still face two major challenges during installation: First, for wall corners that are not right angles or have curved transitions, pre-formed bending parts are usually required in the factory, which cannot adapt to complex size and angle changes on site, resulting in poor flexibility. Furthermore, the joints of the prefabricated parts remain weak points for radiation leakage. Second, it is difficult to monitor the integrity of the protective wall. Usually, it can only be tested during acceptance, and real-time monitoring and leak point location cannot be achieved.

[0004] Therefore, there is an urgent need for a lead-free radiation shielding wall that can be flexibly adapted to the site, achieve a seamless transition, and monitor the protection status in real time. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lead-free radiation shielding partition wall to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a lead-free radiation shielding partition wall, comprising a shielding unit, wherein the shielding unit comprises two outer shielding layers and an inner lining layer sandwiched between the two; the top of the wall is provided with a bendable top panel, and adjacent shielding units are connected by outer shielding panels; Multiple extension blocks are fixedly connected to the outer side of the outer layer, and protective covers are detachably installed on the extension blocks; by selectively removing the protective covers at specific locations, the wall can be bent at the location to form an arc-shaped transition corner. The inner lining is equipped with a control system, which includes a rotatable rotating assembly and a telescopic fixing rod driven by the rotating assembly; when the rotating assembly moves, it drives the telescopic fixing rod to extend and insert into the adjacent outer panel or top panel to achieve locking. The outer display layer is also equipped with multiple interconnected indicator lights, which are electrically connected to the control system and are used to display the radiation protection status in real time. Furthermore, the inner lining layer includes a filling tank shell, into which lead-free protective slurry is poured on-site. The lead-free protective slurry is barium sulfate mortar or a polymer composite material doped with tungsten and bismuth compounds.

[0007] Furthermore, the protective cover is made of rigid PVC or ABS plastic and consists of multiple sections with easy-break points between the sections, making it easy to disassemble in sections according to bending requirements.

[0008] Furthermore, the rotating assembly includes a rotating frame and a semi-circular cam plate fixed to its back; the inner liner has control holes and an inner liner rod for wiring, and in the initial state, the semi-circular cam plate covers the channel entrance of the inner liner rod.

[0009] Furthermore, the telescopic fixing rod is sleeved with a telescopic spring. One end of the telescopic spring is fixed to the inner wall of the outer extension rod of the inner lining layer, and the other end acts on the telescopic fixing rod. One end of the telescopic fixing rod forms a cam driven relationship with the semi-circular cam plate, and the other end is provided with a groove for engaging with the fixing hole on the outer side plate or the top layer plate.

[0010] Furthermore, the top layer is made of flexible PVC or rubber composite material mixed with heavy metal fillers, which has the ability to bend and maintain its shape at room temperature or when heated to 60-80°C.

[0011] Furthermore, the indicator light is an LED light, which is interconnected by a circuit laid inside the inner lining rod, and changes the color of the light emission according to a preset radiation threshold.

[0012] A construction method for lead-free radiation shielding partition walls includes the following steps: S1: On-site filling: Liquid lead-free protective slurry is poured into the filling tank of the inner lining layer and allowed to solidify and take shape. S2: Assembly and initial fixing: Install the filled inner lining layer between the front and rear outer lining layers using the four corner fixing buckles to form a basic protective panel unit; S3: Bending pretreatment: Based on the bending radius and location required at the construction site, determine the area that needs to be bent, and remove the protective cover corresponding to that area in sections to expose the extension block and top layer below; S4: Heating and softening: Use a hot air gun to evenly heat the top layer of the area to be bent, softening it to a highly elastic state that can be bent. S5: Bending and Shaping: Apply external force to slowly bend the wall in the area where the protective cover has been removed, forming the smooth arc required by the design; S6: Locking Connection: Use a tool to insert and rotate the rotation control slot of the rotating kit to drive the telescopic fixing rod to extend and insert into the hole of the adjacent component (outer panel or top panel) to achieve permanent mechanical locking; at the same time, the rotation action opens the cable channel; S7: Wiring and Powering On: Connect the indicator light cables through the opened cable channels and turn on the power to complete the installation and commissioning of the entire system.

[0013] The technical effects and advantages of this invention are as follows: 1. This invention, with its segmented and removable protective cover and bendable top panel, along with flexibly adjustable extension blocks, facilitates the smooth bending and precise shaping of the wall at any arc on-site according to actual needs. It completely replaces traditional prefabricated right-angle components, greatly improving the adaptability of the partition wall to complex and non-standard spatial layouts. Furthermore, by forming a continuous, seamless arc transition, it fundamentally eliminates the risk of radiation leakage at corners, achieving a balance between protective performance and design freedom.

[0014] 2. This invention, through a mechanical intelligent locking system consisting of a rotating assembly and a telescopic fixing rod, and an integrated wiring indicator light network, facilitates a fast, reliable, and irreversible permanent mechanical connection between wall units. Simultaneously, it ensures the standardized layout of signal lines and real-time visual monitoring of protection status, significantly simplifying the construction process and reducing reliance on specialized tools and complex techniques. Thus, while guaranteeing installation quality and structural reliability, it greatly improves construction efficiency.

[0015] 3. This invention, through the inclusion of a rotating assembly, facilitates the simultaneous mechanical locking of the telescopic fixing rod and the opening of the inner liner cable channel with a single rotation of the unique semi-circular cam plate. This combines two key installation steps into one, ensuring the durability and reliability of the connection through mechanical interlocking, while also providing a convenient channel for the wiring of the indicator light network. This greatly simplifies on-site construction operations, avoids errors that may arise from multi-step operations, and significantly improves installation accuracy. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The lead-free radiation shielding partition wall involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figure 1 and Figure 2 This invention provides a lead-free radiation shielding partition wall, comprising a wall body assembled from multiple shielding panel units. Each shielding panel unit is a "sandwich" structure, consisting of two outer protective layers 1 (material can be high-strength ABS engineering plastic, serving both decorative and protective functions) and a middle inner lining layer 2. The inner lining layer 2 is installed on the outer protective layers 1 via fixing clips 205 at its four corners. The inner lining layer 2 is smaller than the outer protective layers 1, thus creating an installation space around its perimeter. The vertical joints of the wall are connected by the outer panel 3, while the horizontal joints and bends are achieved by the top panel 4. The protective cover 5, serving as both a decorative and functional cover, is installed on the extension block 102.

[0025] In this embodiment, it should be specifically noted that the core protective materials of the outer side panel 3 and the top layer panel 4 are the same as the filling material of the inner lining layer 2, ensuring the continuity of protection. The top layer panel 4 uses a more flexible formulation (such as adding plasticizers to the PVC matrix), giving it excellent bending performance.

[0026] The protective cover 5 is made of rigid PVC and consists of multiple segments, each with a pre-set V-shaped easy-break point. When installed on a straight wall, no bending is required; all protective covers 5 are installed in place, serving both decorative and structural reinforcement purposes. When bending is necessary, the installer calculates the specific bending point based on the designed curve, then breaks off the corresponding protective cover segment 5 by hand or with tools and removes it. After removal, the top shelf 4 and extension block 102 in that area lose their lateral constraints and become freely movable. At this point, external force can be applied to create a smooth bend in the wall, forming an arc-shaped corner, fundamentally avoiding right-angle joints.

[0027] Reference Figure 2 The outer side panel 3 includes a side panel main board 301, on which a side panel fixing hole 302 is provided; the top panel 4 includes a top panel main board 401, on which a top panel fixing hole 402 is provided; both the side panel fixing hole 302 and the top panel fixing hole 402 are fixedly installed with locking blocks. When the telescopic fixing rod 7 is inserted into them, it forms a mechanical interlock with the locking blocks to achieve permanent fixation. This fixing method only allows removal by violent destruction; adjacent protective panel units are fixedly connected through the outer side panel 3 or the top panel 4, and adjacent walls above and below are connected by a continuous arc transition through the top panel 4 with the same bending angle.

[0028] Reference Figure 3-4 The outer display layer 1 has an outer channel hole 101 for installing indicator lights 6. Multiple indicator lights 6 are interconnected by wiring laid inside the inner liner rod 204 (which is a hollow flexible pipe) to form a monitoring network.

[0029] In this embodiment, it should be specifically noted that the inner lining rod 204 is installed in the inner lining layer 2, which serves as a signal transmission function and a steel reinforcement support for the filling material, thus facilitating the stability of the filling material.

[0030] Reference Figure 4 The core of the inner lining layer 2 is a filling tank 201, which is filled with a high-density lead-free protective slurry (such as barium sulfate mortar) during on-site construction. Multiple control holes 202 are fixed inside the filling tank 201, connected by an inner lining rod 204, and connected to the outside via an outward extension rod 203. The rotating assembly 9 is installed within the control holes 202.

[0031] Reference Figure 5The telescopic fixing rod 7 and the telescopic spring 8 are installed inside the outward extension rod 203. The telescopic fixing rod 7 and the telescopic spring 8 are sleeved together. The two ends of the telescopic spring 8 are respectively fixed to the inner wall of the outward extension rod 203 and the flange of the telescopic fixing rod 7, thereby applying an inward restoring force to the telescopic fixing rod 7. One end of the telescopic fixing rod 7 extends into the control hole 202 and forms a cam driven structure with the semi-circular cam plate 902 on the rotating assembly 9 located therein. The other end has a slot and points outward. When the rotating assembly 9 rotates, the semi-circular cam plate 902 acts as a cam to push the telescopic fixing rod 7 to extend outward against the elastic force of the telescopic spring 8. The slot at its front end engages with the locking block, thereby firmly fixing the adjacent protective plate unit through the outer plate 3 or the top plate 4.

[0032] In this embodiment, it should be specifically noted that the indicator light (6) (which may be an RGB LED) emits green light under normal conditions, indicating safety. Radiation sensors (not shown in the figure) are integrated inside the walls on both sides of the outer channel hole (101). Both the sensors and the indicator light (6) are electrically connected to the control system. When the sensor detects that the radiation dose at a certain location exceeds the safety threshold (e.g., 2.5 μSv / h), the control system controls the indicator light (6) in that area to turn into a flashing red light, accurately indicating the location of the leak and realizing intelligent visual monitoring.

[0033] Reference Figure 6 The rotating assembly 9 consists of a rotating frame 901 and a semi-circular cam plate 902. The telescopic fixing rod 7 and the telescopic spring 8 are installed inside the outward extension rod 203 and are sleeved together. The telescopic spring 8 provides an inward restoring force for the telescopic fixing rod 7.

[0034] In this embodiment, it should be specifically noted that: during the initial installation, the rotating kit 9 ​​is in its initial position, with its semi-circular cam plate 902 on its back precisely covering the channel entrances of the two inner lining rods 204, preventing grout from flowing in during grouting. When it is necessary to lock adjacent walls, a special tool is used to engage the rotating control groove 903, and the rotating frame 901 is rotated (e.g., rotated 90°). The semi-circular cam plate 902 rotates accordingly, and its circumferential surface acts as a cam, pushing the telescopic fixing rod 7 to extend outward against the elastic force of the telescopic spring 8. The end of the telescopic fixing rod 7 is finally inserted into the side plate fixing hole 302 of the adjacent outer side plate 3 (or the top plate fixing hole 402 of the top layer plate 4), achieving a firm mechanical lock. This connection is a one-time permanent connection and can only be removed by breaking it. At the same time, the rotated semi-circular cam plate 902 clears the channel of the inner lining rod 204, facilitating the subsequent insertion of the indicator light 6 cable.
