These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] Figure 1This is a schematic diagram of the structure of a radiation detection shielding device provided in an embodiment of this application. Figure 2 yes Figure 1 The top view of the X-ray detection shielding device shown is shown. Figure 3 yes Figure 1 The diagram shows a scenario where a radiation detection shielding device can be used. (Combined with...) Figure 1 , Figure 2 and Figure 3 As shown, the X-ray inspection shielding device 10 is used to mount a target workpiece 31 on a bearing surface 21. The target workpiece 31 includes a target side surface 311. Specifically, the X-ray inspection shielding device 10 includes: a first support plate 11, a second support plate 12, an elastic component 13, a first shielding plate 14, and a second shielding plate 15. The edge of the first support plate 11 is rotatably connected to the edge of the second support plate 12, and the first support plate 11 is configured to be disposed on the bearing surface 21.

[0025] The elastic component 13 is connected to the first support plate 11 and the second support plate 12 respectively. When the second support plate 12 contacts the target side 311 of the target workpiece 31, the elastic component 13 is configured to push the second support plate 12 so that the second support plate 12 abuts against the target side 311 of the target workpiece 31.

[0026] The first shielding plate 14 is attached to the side of the first support plate 11 away from the bearing surface 21, and the second shielding plate 15 is attached to the side of the second support plate 12 close to the first shielding plate 14.

[0027] In summary, this application provides a radiation detection shielding device. The edges of a first support plate and a second support plate are rotatably connected. The first support plate is disposed on a bearing surface. Elastic components are connected to both the first and second support plates. When the second support plate contacts the target side of the target workpiece, the elastic components push the second support plate to abut against the target side of the workpiece. The first shielding plate is attached to the side of the first support plate away from the bearing surface, and the second shielding plate is attached to the side of the second support plate close to the first shielding plate. This application uses the elastic components to press the second support plate against the side of the target workpiece, reducing the gap between the second shielding plate and the target workpiece and improving the shielding effect. Furthermore, the first shielding plate on the first support plate can also shield radiation reflected from the bearing surface, preventing this radiation from affecting the detection results, further improving the shielding effect of the radiation detection shielding device.

[0028] In one exemplary embodiment, the X-ray inspection shielding device further includes a rotating shaft assembly 16, which is connected to the edges of the first support plate 11 and the second support plate 12, respectively. The rotating shaft assembly 16 provides a stable center of rotation for the first support plate 11 and the second support plate 12, constraining them to rotate around the assembly, thus enabling controllable relative movement between the two support plates. Simultaneously, it effectively converts the driving force of the elastic component 13 into a clamping force on the target workpiece 31. In this embodiment, the rotating shaft assembly 16 may specifically include a hinge, a hinge joint, and / or at least one of a pin passing through corresponding shaft holes on the edges of the first support plate 11 and the second support plate 12. In this embodiment, the first support plate 11 and the second support plate 12 can rotate relative to each other within an angle range of 30 to 150 degrees under external force.

[0029] In one exemplary embodiment, the first shielding plate 14 and the second shielding plate 15 remain continuous and bend at the pivot assembly 16, without needing to be tightly fitted to the mechanical structure of the pivot assembly 16. This structure ensures that even at rotating parts, radiation will not leak from the seams of the shielding plates, ensuring the integrity of the shielding effect and avoiding wear and tear of the shielding plates caused by frequent rotation. Furthermore, because a tight fit is not required, the manufacturing precision requirements are reduced, simplifying the processing and installation of the first shielding plate 14 and the second shielding plate 15.

[0030] In one exemplary embodiment, the elastic component 13 includes at least one spring sheet 131, which includes a first spring sheet 1311 and a second spring sheet 1312. The first spring sheet 1311 and the second spring sheet 1312 are connected, and there is an included angle greater than 90 degrees between the first spring sheet 1311 and the second spring sheet 1312. The first spring sheet 1311 is connected to a first support plate 11, and the second spring sheet 1312 is connected to a second support plate 12. When the X-ray inspection shielding device is placed on the target workpiece 31, after the second support plate 12 contacts the target side 311 of the target workpiece 31, the first support plate 11 is pushed closer to the second support plate 12, causing the included angle between them to decrease, thereby compressing the spring sheet 131, pressing it from an initial large angle (e.g., 135°) to a smaller angle (e.g., 100°). This deformation process stores elastic potential energy. To restore its original shape, the spring plate 131 applies a reaction force to the first support plate 11 and the second support plate 12, thereby generating a strong restoring torque. This torque acts on the second support plate 12, pressing it tightly against the target side 311 of the target workpiece 31. This ensures that a constant clamping force is maintained between the shielding plate and the target workpiece 31 throughout the entire inspection process, ensuring reliable shielding effectiveness. Furthermore, since the spring's deformation is proportional to the force it provides, when encountering abnormalities such as protrusions on the target side 311, the spring plate 131 can buffer the impact through greater deformation, preventing hard damage to the device or workpiece. Compared to other structures that can provide thrust to the second support plate 12, using the spring plate 131 allows the elastic component 13 to automatically complete the clamping action simply by placing the device in place and giving it a gentle push. Operators do not need to perform tedious bolt tightening operations, greatly improving inspection efficiency.

[0031] In one exemplary embodiment, the ends of the first spring sheet 1311 and the second spring sheet 1312 are provided with mounting holes, and are respectively fastened to the first support plate 11 and the second support plate 12 by screws. To ensure the connection is firm and to distribute stress, in this embodiment, a rigid washer may be added between the spring sheet and the support plate.

[0032] In one exemplary embodiment, there are two spring plates 131. The first spring plate 1311 of the two spring plates 131 is connected to both ends of the first support plate 11 in the first direction f, and the second spring plate 1312 of the two spring plates is connected to both ends of the second support plate 12 in the first direction f, where the first direction f is the extension direction of the edge connecting the first support plate 11 and the second support plate 12. The two spring plates 131 are symmetrically arranged at both ends of the first support plate 11 and the second support plate 12, and can push the second support plate 12 from both sides together, ensuring that the clamping force is evenly distributed along the first direction f. The double support point structure improves the overall rigidity of the device when subjected to lateral force or vibration, making it more stable during operation and less prone to positional displacement. It prevents the second support plate 12 from twisting or tilting due to single-point drive, and avoids local gaps caused by uneven force, so that the second shielding plate 15 on the entire second support plate 12 can be tightly fitted with the target side 311.

[0033] In addition, the elastic component 13 can also be other structures. For example, the elastic component 13 may include two hydraulic rods, each hydraulic rod including a hydraulic cylinder and a hydraulic rod mounted on the hydraulic cylinder. The hydraulic cylinder can be fixedly connected to the first support plate 11, and the hydraulic rod is rotatably connected to the second support plate 12 (for example, the second support plate 12 may be provided with a connecting piece with an opening, and one end of the hydraulic rod is rotatably connected to the connecting piece of the hydraulic cylinder). The extension and retraction direction of the hydraulic rod has an angle greater than zero degrees and less than or equal to 45 degrees with the plate surfaces of the first support plate 11 and the second support plate 12. In this way, the hydraulic cylinder can push the hydraulic rod to extend so that the second support plate 12 can abut against the target surface of the target workpiece.

[0034] In one exemplary embodiment, a first spring is connected to a first support plate via a first adjustable base, and a second spring is connected to a second support plate via a second adjustable base. The first adjustable base includes a first base fixed to the first support plate, a first slider movable back and forth within a groove in the first base in a direction parallel to the first support plate, and a first adjusting bolt for locking the first slider. The end of the first spring is connected to the first slider via a first hinge shaft. The second adjustable base includes a second base fixed to the second support plate, a second slider movable back and forth within a groove in the second base in a direction parallel to the second support plate, and a second adjusting bolt for locking the second slider. The end of the second spring is connected to the second slider via a second hinge shaft. By loosening the first adjusting bolt and the second adjusting bolt respectively, the positions of the first slider and the second slider can be adjusted independently, thereby synchronously changing the effective lever arm between the two ends of the spring and the rotating shaft assembly. This dual-adjustment mechanism can precisely control the initial preload and effective stiffness of the spring sheet. After tightening the bolt, the position can be fixed. By independently adjusting the lever arm length at both ends of the spring sheet, the required clamping force can be precisely matched according to the weight, surface characteristics and placement angle of the target workpiece, ensuring the shielding effect while avoiding excessive compression of the precision workpiece.

[0035] In one exemplary embodiment, the second support plate 12 has a shielding region. The orthographic projection of the target workpiece 31 onto the second support plate 12 lies within the shielding region, while the orthographic projection of the second spring piece 1312 onto the second support plate 12 lies outside the shielding region. The size and shape of the shielding region can be determined based on the dimensions of the target workpiece 31 and the typical angle of the X-ray beam. During X-ray irradiation, only the X-rays passing through the shielding region will be imaged on the film. By placing the second spring piece 1312 outside the shielding region, the possibility of the elastic component 13 forming false defect images on the film is fundamentally eliminated, ensuring that the second spring piece 1312 will not leave any image on the final X-ray film. This allows operators to clearly and accurately identify and judge the true defects inside the target workpiece, greatly improving the reliability and accuracy of the inspection results.

[0036] In one exemplary embodiment, the second support plate 12 includes a support plate body 121 and a flexible shielding layer 122. The edge of the support plate body 121 is rotatably connected to the edge of the first support plate 11. The second shielding plate 15 is attached to the side of the support plate body 121 closest to the first support plate 11, forming an angle with the first shielding plate 14. The flexible shielding layer 122 is attached to the side of the support plate body 121 away from the second shielding plate 15. The other side of the flexible shielding layer 122 contacts the target side surface 311 of the target workpiece 31. In related technologies, gaps caused by uneven surfaces are unavoidable between the lead plate and the side surface of the workpiece, and radiation leaks from these gaps, causing edge erosion. In this embodiment, by setting the contact surface with the target side surface 311 as a flexible shielding layer 122, it has a certain deformation capability and can conform to any irregularities of the target side surface 311, filling all possible tiny gaps that are invisible to the naked eye. Under certain thrust and extrusion, the flexible shielding layer 122 can completely fit the target side 311 of the target workpiece 31, preventing radiation from leaking from the gap between the target side 311 and the radiation detection shielding device, thus improving the shielding effect of the radiation detection shielding device.

[0037] In one exemplary embodiment, the flexible shielding layer 122 includes a flexible substrate layer and a plurality of shielding particles distributed within the flexible substrate layer. The material of the shielding particles includes at least one of bismuth, tungsten, and lead. In this embodiment, the flexible substrate layer can be manufactured using silicone rubber, polyurethane, or nitrile rubber. The shielding particles are spherical or near-spherical lead-bismuth alloy microspheres with a particle size distribution between 50 μm and 210 μm and a volume fill rate of 60% to 80%. The manufacturing process employs mixing, calendering, and vulcanization to ensure uniform particle distribution and strong bonding with the matrix. The flexible shielding layer obtained in this manner is a one-piece solid component with excellent mechanical properties and durability. Other materials can also be used for the flexible substrate layer, and the particle size and volume fill rate of the shielding particles are not limited in this embodiment.

[0038] In one exemplary embodiment, the flexible shielding layer includes a flexible outer shell and shielding powder located within the flexible outer shell. The shielding powder is made of at least one of bismuth, tungsten, and lead. In this embodiment, the flexible outer shell is a sealed capsule made of at least one of polyvinyl chloride and / or thermoplastic polyurethane composite materials, internally divided into multiple independent, interconnected chambers. This design prevents excessive powder accumulation in any one area. The shielding powder is a lead-tungsten mixed powder obtained by atomization. After filling, it is completely sealed by evacuation and filling with a small amount of inert gas (such as nitrogen) to prevent oxidation and moisture absorption. The flexible shielding layer obtained in this way is lighter and has excellent flexibility, adapting to more complex curved surfaces. When the target side 311 of the target workpiece 31 is not a flat shape, a flexible shielding layer including a flexible outer shell and shielding powder located within the flexible outer shell can be used. By adjusting the metal material ratio, particle / powder filling rate, and the thickness of the flexible layer, the flexible shielding layer can conform to any shape of the target workpiece 31, improving the flexibility of the X-ray inspection shielding device.

[0039] In one exemplary embodiment, the first support plate 11 and the support plate body 121 are made of stainless steel. The first support plate 11 and the support plate body 121 not only bear the first shielding plate 14 and the second shielding plate 15, but also resist the bending and torsional moments caused by the reaction forces of the elastic component 13 and the target workpiece 31. Stainless steel plates have high strength and high rigidity, ensuring that the geometry of the entire device remains unchanged under stress. Furthermore, stainless steel plates also have a certain degree of corrosion resistance, ensuring that the device can be used for a long time in industrial environments (where it may come into contact with water, chemical reagents, etc.) without rusting, thus improving the service life of the X-ray detection shielding device.

[0040] In one exemplary embodiment, the X-ray inspection shielding device further includes a pressing component 17, which is located on the first shielding plate 14, and the mass of the pressing component 17 is greater than the sum of the masses of the first support plate 11, the second support plate 12, the elastic component 13, the first shielding plate 14, and the second shielding plate 15. When the elastic component 13 pushes the second support plate 12 against the target workpiece 31, it generates a reaction force of equal magnitude and opposite direction. This reaction force tends to cause the entire X-ray inspection shielding device to move away from the target workpiece 31 around its grounding point. The pressing component 17 generates a stabilizing torque through its huge self-weight. This stabilizing torque must be greater than the overturning torque caused by the reaction force of the elastic component 13, thereby firmly fixing the X-ray inspection shielding device on the bearing surface 21 and keeping it absolutely stationary. In this embodiment, the pressing component 17 can be a single cast iron or lead block, or it can be composed of multiple standard counterweights. When facing target workpieces 31 of different sizes and weights, or when the elastic component 13 is replaced with a model of different stiffness, the stabilizing torque can be flexibly adjusted by adding or removing counterweights.

[0041] In one exemplary embodiment, the side of the first support plate 11 that contacts the bearing surface 21 has a composite anti-slip structure. The composite anti-slip structure includes multiple serrated metal strips and rubber pads adhered between the metal strips. The multiple serrated metal strips are positioned on the side of the first support plate that contacts the bearing surface for a cutting-in grip on rough or soft bearing surfaces. The rubber pads, filled between the multiple serrated metal strips, provide significant static friction on smooth, hard bearing surfaces, eliminating minor slippage that may occur after the device presses against the workpiece, ensuring the stability of the shielding position, and resisting horizontal reaction forces from the elastic components and possible accidental collisions while preventing the first support plate from slipping. Furthermore, the thickness of the rubber pad perpendicular to the first direction is greater than the thickness of the serrated metal strips perpendicular to the first direction. When placing the first support plate, the rubber pad contacts the bearing surface first, preventing the hard metal base plate from directly scratching the precision testing platform or workbench, thus providing protection.

[0042] Figure 3 This illustration shows a schematic diagram of a usage scenario for the radiation detection shielding device provided in an embodiment of this application, combined with... Figure 1 and Figure 2As shown, the target workpiece 31 is placed on the support surface 21. The X-ray tube 32 is located above the target workpiece 31, and the X-ray radiation it generates covers the upper area of ​​the target workpiece 31 in a cone shape. The X-ray inspection shielding device 10 of this embodiment is placed on one side of the target workpiece 31. The first support plate 11 is placed flat on the support surface 21, and the second support plate 12 is automatically attached to the target side 311 of the target workpiece 31 by the pressure of the elastic component 13. The pressing component 17 is placed on the first shielding plate 14 covering the first support plate 11 to ensure that the entire device is absolutely stationary during the exposure process and to avoid shielding failure caused by small displacements. The overall width design of the X-ray inspection shielding device 10 ensures that the elastic components 13 on both sides will not project onto the effective film area. The flexible shielding layer 122 on the outside of the second support plate 12 maintains close contact with the target side 311. The primary X-ray beam 321 emitted from the X-ray tube 32 shines downward at a certain angle, passing through the upper area of ​​the target workpiece 31. Some of the rays directly penetrate the target workpiece 31 and form an image on the film below, which is the effective information required for inspection. When the rays interact with the material of the target workpiece 31, scattered rays are generated in various directions. The flexible shielding layer 122 on the second support plate 12 is in close contact with the target side 311, blocking the scattered rays propagating along the target side 311. The second shielding plate 15 provides the main shielding capability, while the flexible shielding layer 122 ensures a seamless and close contact, fundamentally eliminating the conditions for edge erosion. The first shielding plate 14 on the first support plate 11 shields the scattered rays leaking from below the side of the target workpiece 31, as well as the scattered rays reflected after irradiating the bearing surface 21. The shielding at the rotating shaft assembly 16 is achieved by the bending and fitting of the shielding plates on the first support plate 11 and the second support plate 12, ensuring continuous shielding in the corner area.

[0043] Furthermore, the thickness of the first shielding layer and the second shielding layer can be positively correlated with the accelerating voltage of the ray tube 32. For example, the greater the accelerating voltage of the ray tube 32, the thicker the first shielding layer and the second shielding layer.

[0044] This application provides an embodiment of a radiation detection shielding device for shielding one target side of a target workpiece 31. When the target workpiece 31 includes multiple target sides, multiple radiation detection shielding devices provided in this application can be used to shield the multiple target sides. For example, if the target workpiece 31 is a cubic workpiece with four target sides, then four radiation detection shielding devices provided in this application can be used to shield the four target sides.

[0045] In summary, this application provides a radiation detection shielding device. The edges of a first support plate and a second support plate are rotatably connected. The first support plate is disposed on a bearing surface. Elastic components are connected to both the first and second support plates. When the second support plate contacts the target side of the target workpiece, the elastic components push the second support plate to abut against the target side of the workpiece. The first shielding plate is attached to the side of the first support plate away from the bearing surface, and the second shielding plate is attached to the side of the second support plate close to the first shielding plate. This application uses the elastic components to press the second support plate against the side of the target workpiece, reducing the gap between the second shielding plate and the target workpiece and improving the shielding effect. Furthermore, the first shielding plate on the first support plate can also shield radiation reflected from the bearing surface, preventing this radiation from affecting the detection results, further improving the shielding effect of the radiation detection shielding device.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0047] In this application, the term "at least one of A and B" merely describes the relationship between related objects, indicating that three relationships can exist. For example, "at least one of A and B" can represent: A existing alone, A and B existing simultaneously, and B existing alone. Similarly, "at least one of A, B, and C" indicates that seven relationships can exist, representing: A existing alone, B existing alone, C existing alone, A and B existing simultaneously, A and C existing simultaneously, C and B existing simultaneously, and A, B, and C existing simultaneously.
