Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ray shielding devices, in particular to a ray shielding protection screen. Background Art
[0002] In the field of radiation protection technology, traditional radiation shielding screens rely primarily on thick, heavy lead plates as their core components. Due to their high density and excellent radiation absorption, lead plates are widely used in medical, scientific research, industrial flaw detection, and other applications requiring radiation protection. However, these traditional radiation shielding screens have significant limitations in design and use.
[0003] First, the rigidity and weight of lead sheet material are significant drawbacks. Lead's high density makes lead shields not only bulky but also extremely inconvenient to transport, install, and operate. Moving or adjusting the shield's position, in particular, often requires considerable physical effort and time. Furthermore, the rigidity of lead sheet material limits its flexibility during use.
[0004] Secondly, traditional lead shields have poor bending properties. Due to the material properties of lead, once bent, it is difficult to restore to its original shape and position. This not only affects the aesthetics and durability of the shield, but can also negatively impact its radiation protection effectiveness. In applications where frequent adjustments to the shield's shape and angle are necessary, such as radiation shielding devices in scientific research experiments, traditional lead shields clearly cannot meet this requirement.
[0005] Therefore, traditional radiation shielding screens have obvious deficiencies in terms of material, weight, bending performance, etc. These limitations not only restrict the scope and flexibility of the shields, but also increase the risks and costs during their use. Utility Model Content
[0006] In view of the above problems, the present application provides a radiation shielding protective screen to facilitate the bending and restoration of the protective screen.
[0007] To achieve the above objectives, the present application provides a radiation shielding protective screen, comprising:
[0008] A shielding unit comprising a plurality of stacked shielding plates; the shielding plates comprising a first region and a second region, the second region being an annular region and disposed around the first region; and a plurality of folds being preset on the first region to facilitate bending of the shielding plates;
[0009] The housing has a built-in accommodating cavity for accommodating the shielding unit, the shielding unit is placed in the accommodating cavity, and the housing is used to protect the shielding unit.
[0010] In the technical solution of the embodiment of the present application, a plurality of through holes are arranged in an array in the first area, and the through holes between two adjacent shielding plates are arranged in a staggered manner.
[0011] In the technical solution of the embodiment of the present application, the through holes located on different shielding plates are staggered in the vertical direction.
[0012] In the technical solution of the embodiment of the present application, the shielding plate is a lead shielding plate.
[0013] In the technical solution of the embodiment of the present application, the fold includes: a first fold line and a second fold line, the first fold line and the second fold line are connected to each other, and there is a non-zero angle between the first fold line and the second fold line.
[0014] The technical solution of the embodiment of the present application further includes: a handle, which is placed in the edge area of the shell; there are multiple handles, and the multiple handles are arranged around the accommodating cavity.
[0015] In the technical solution of the embodiment of the present application, the handle is a handle hole, and the handle hole passes through the edge of the shell.
[0016] In the technical solution of the embodiment of the present application, the shielding plate is a quadrilateral, the first region includes four edges that are respectively parallel to the four edges of the shielding plate, and two adjacent edges are connected by an arc;
[0017] The extended lines and arcs of the adjacent edges enclose a first sub-region, a second sub-region, a third sub-region and a fourth sub-region in the second region;
[0018] The areas of the first sub-region, the second sub-region, the third sub-region and the fourth sub-region are different.
[0019] Unlike existing technologies, this solution utilizes multiple stacked shielding panels with pre-defined creases in the first region of the panels, allowing the shield to be easily bent and adaptable to various complex spatial layouts. This not only facilitates installation and transportation, but also allows users to adjust the shield's shape and angle to meet specific needs, significantly increasing its flexibility and adaptability, enabling more comprehensive coverage of equipment. While traditional lead sheets offer excellent radiation protection, the new shield, through its multi-layered design, promises even more precise radiation shielding control. Different layers of shielding panels can be optimized for different energy levels, providing more comprehensive and effective protection. Thanks to its multi-layered structure and pre-defined creases, the new shield easily returns to its original state after bending, reducing the risk of deformation and damage from prolonged bending. This not only extends the shield's lifespan but also reduces maintenance costs. Compared to heavy lead sheets, the new shield's multi-layered design allows for a lighter weight. This not only facilitates transportation and installation, but also enhances its portability, making it easier to move between locations and reuse.

[0042] See also Figures 1 to 6 In this embodiment, a radiation shielding protective screen includes:
[0043] The shielding unit 10 includes a plurality of stacked shielding plates 11. The shielding plates 11 include a first region 111 and a second region 112. The second region 112 is an annular region and is disposed around the first region 111. The first region 111 is provided with a plurality of folds 113 to facilitate bending of the shielding plate 11.
[0044] The housing 20 has a built-in accommodating cavity for accommodating the shielding unit 10 . The shielding unit 10 is placed in the accommodating cavity. The housing 20 is used to protect the shielding unit 10 .
[0045] The shielding unit 10 includes a plurality of shielding plates 11 , and the plurality of shielding plates 11 are stacked and each shielding plate 11 has the same structure; each shielding plate 11 is divided into the first area 111 and the second area 112 .
[0046] The first region 111 is provided with a plurality of folds 113. These folds 113 allow the shielding plate 11 to bend at these folds 113, as needed, to accommodate different shielding requirements or installation conditions. Furthermore, the folds 113 may extend through the shielding plate 11 or may be grooves or markings formed on the shielding plate 11.
[0047] The second area 112 is an annular area, which is arranged around the first area 111 to form a frame structure to improve the strength of the shielding plate 11; the annular setting not only enhances the overall structural strength of the shielding plate 11, but also helps to disperse and absorb rays from different directions, thereby improving the shielding effect.
[0048] Multiple shielding plates 11 are stacked together to form an integrated shielding unit 10. This stacking arrangement not only further enhances the shielding effect but also allows for adjustment of the number and thickness of shielding plates 11 to meet different shielding requirements. Furthermore, the thinness of each shielding plate 11 improves bending and recovery efficiency.
[0049] It should also be noted that the dimensions of the shielding plate 11 include but are not limited to 600mm*600mm and 800mm*800mm.
[0050] The housing 20 defines a cavity for accommodating and securing the shielding unit 10. The cavity's shape and size match the shielding unit 10 to ensure its stable placement. The housing 20 protects the shielding unit 10 from environmental damage, such as impact, abrasion, or corrosion. Furthermore, the housing 20 provides a well-sealed environment for the shielding unit 10.
[0051] When the radiation shielding protective screen is in working condition, the radiation will first encounter the external barrier of the shell 20. Since the material and thickness of the shell 20 have a certain shielding ability, it can initially block or weaken the intensity of the radiation. The radiation will then enter the accommodating cavity inside the shell 20 and contact the stacked shielding unit 10. The multiple shielding plates 11 in the shielding unit 10 further absorb and scatter the radiation through the high-density material inside. Furthermore, since a plurality of folds 113 are preset on the first area 111, the shielding plate 11 can be bent when needed to adapt to different installation conditions and shielding requirements. This flexibility not only improves the shielding effect, but also increases the scope of application of the protective screen, so that the protective screen can be effectively attached to the equipment.
[0052] Unlike existing technologies, this technical solution utilizes multiple stacked shielding panels 11 and pre-designed creases 113 in the first region 111 of the shielding panels 11, allowing the shield to be easily bent and adaptable to various complex spatial layouts. This not only facilitates installation and transportation, but also allows users to adjust the shape and angle of the shield according to actual needs, significantly increasing its flexibility and adaptability, thereby ensuring more comprehensive coverage of equipment. While traditional lead sheets provide excellent radiation protection, the new shield, through the multi-layer design of shielding panels 11, offers the potential for more refined radiation shielding control. Different layers of shielding panels 11 can be optimized for different energy levels, providing more comprehensive and effective protection. Due to its multi-layer structure and pre-designed creases 113, the new shield can more easily return to its original state after bending, reducing the risk of deformation and damage caused by long-term bending. This not only extends the shield's service life but also reduces maintenance costs. Compared to heavy lead sheets, the new shield's multi-layer design makes it possible to achieve a lighter weight. This not only facilitates transportation and installation, but also improves the portability of the protective screen, making it easier to move and reuse between different sites.
[0053] According to some embodiments of the present application, referring to Figure 3 、 Figure 4 as well as Figure 6 A plurality of through holes 114 are arranged in an array in the first area 111 , and the through holes 114 between two adjacent shielding plates 11 are staggered.
[0054] The through-holes 114 are arranged in an array within the first region 111, and are evenly distributed in the array. Furthermore, the through-holes 114 between two adjacent shielding plates 11 are staggered. When a through-hole 114 is located at a certain position on the upper shielding plate 11, the corresponding position on the lower shielding plate 11 is absent. This staggered arrangement further increases the difficulty for radiation to penetrate the multiple shielding plates 11, thereby improving shielding efficiency.
[0055] Since mechanical punching only causes the lead material on the lead plate to diffuse around the hole and does not reduce the mass of the lead material that constitutes the lead plate, the overall mass of the punched lead plate is consistent with the original solid lead plate. According to the basic theory of radiation protection: the mass attenuation coefficient μ value does not change due to changes in the physical state of the material, the overall mass of the punched lead plate remains unchanged and the overall protection effect remains unchanged.
[0056] To sum up, the staggered punching of each shielding plate 11 and the staggered placement of the lead plates of the radiation shielding protection screen ensure that the protection effect remains unchanged, and also bring softness and elasticity during transportation, installation and disassembly, and maintain the original shape of the multi-layer lead plates and prevent them from deformation.
[0057] The shielding plate 11 material should be selected from metal or alloy materials with high density and good radiation absorption ability, such as lead, tungsten, etc. These materials can effectively block and scatter radiation and improve the shielding effect.
[0058] Figure 5 Solid rectangle and Figure 2 The dotted rectangular frame is the lead plate (shielding plate 11) area of the shielding protection screen, which is generally square or rectangular; Figure 5 The dotted line (i.e., the first area 111) is within the punching area. By reserving the first sub-area 1121, the second sub-area 1122, the third sub-area 1123 and the fourth sub-area 1124 of different areas at the four corners of the first area 111, the mass center point of the first area 111 of each shielding plate 11 is staggered with the center point of the shielding plate 11, and the center points of the first areas 111 are also staggered. In this way, it is ensured that the punching positions of each shielding plate 11 do not overlap as a whole, and no holes are formed that pass through the shielding unit 10.
[0059] When the radiation shielding protective screen is in working state, the through holes 114 staggered between the multi-layer shielding plates 11 can prevent radiation from passing through the through holes 114. Specifically, when radiation attempts to penetrate the shielding plates 11, they will encounter obstructions from the through holes 114.
[0060] In some embodiments, because through-holes 114 are arranged in an array, radiation is scattered multiple times and deviates from its original direction during penetration. Furthermore, the staggered arrangement of through-holes 114 between adjacent shielding plates 11 ensures that radiation encounters more obstruction and scattering when penetrating the multi-layer shielding plates 11. This design not only improves shielding effectiveness but also increases the flexibility of the shield, adapting it to varying shielding requirements and installation conditions.
[0061] The diameter of the through hole 114 is about 0.1 to 0.25 mm, and the hole spacing is about 5 to 10 mm.
[0062] According to some embodiments of the present application, referring to Figure 6 The through holes 114 on different shielding plates 11 are staggered in the vertical direction.
[0063] The number of layers of the shielding plate 11 is preferably 4-6. In order to further improve the efficiency of shielding rays, the through holes 114 of each layer are staggered. Specifically, taking the shielding plate 11 with 3 layers as an example, the orthographic projections of the through holes 114 of the first layer on the second shielding plate 11 and the third shielding plate 11 do not intersect with the through holes 114 of the second shielding plate 11 and the third shielding plate 11.
[0064] According to some embodiments of the present application, the shielding plate 11 is a lead shielding plate 11 .
[0065] According to some embodiments of the present application, referring to Figures 4 and 5 The fold 113 includes: a first fold line 1131 and a second fold line 1132, the first fold line 1131 and the second fold line 1132 are connected to each other, and there is a non-zero angle between the first fold line 1131 and the second fold line 1132.
[0066] The first fold lines 1131 are arranged in an array to form a first array pattern; the second fold lines 1132 are arranged in an array to form a second array pattern; the first array pattern and the second array pattern are arranged alternately. Preferably, the first fold lines 1131 and the second fold lines 1132 are perpendicular to each other.
[0067] To increase the flexibility and durability of the shielding plate 11, the first fold line 1131 and the second fold line 1132 can be formed on the shielding plate 11 through indentations, scoring, or other methods, without disrupting the overall structure of the shielding plate 11. Furthermore, the depth and width of the fold line 113 can be adjusted as needed to accommodate different bending radii and strength requirements. Furthermore, the first fold line 1131 and the second fold line 1132 divide the shielding plate 11 into strips or small pieces, improving bending and resetting efficiency.
[0068] When the shielding plate 11 needs to be bent to fit a specific shape or space, the operator can bend the shielding plate 11 along the first fold line 1131 and / or the second fold line 1132. Because these two fold lines form an angle on the shielding plate 11, the shielding plate 11 can be guided to bend in a specific manner without causing structural damage or performance degradation.
[0069] During the bending process, the shielding plate 11 divided by the first fold line 1131 and the second fold line 1132 will deform. However, because they are interconnected, they can jointly withstand the stress caused by the bending. At the same time, the presence of the fold line 113 allows the shielding plate 11 to deform more easily along the predetermined path during bending, thereby improving the efficiency and accuracy of the bending.
[0070] According to some embodiments of the present application, referring to Figures 1 to 2 , further comprising: a handle 30, wherein the handle 30 is disposed in the edge area of the shell 20; the handle 30 is multiple, and the multiple handles 30 are disposed around the accommodating cavity.
[0071] The edge area of the shell 20 has a certain width. Specifically, there is a distance between the outer edge of the accommodating cavity and the outer edge of the shell 20. This distance can be used to install structures such as the handle 30 and / or positioning holes.
[0072] The handle 30 is a concave structure, and both ends of the handle 30 are connected to the edge area of the housing 20. Figure 2 The handle 30 is a handle hole that passes through the edge of the shell 20.
[0073] According to some embodiments of the present application, referring to Figures 3 to 5 , the shielding plate 11 is a quadrilateral, the first region 111 includes four edges that are parallel to the four edges of the shielding plate 11, and two adjacent edges are connected by an arc;
[0074] The extension lines and arcs of the adjacent edges enclose in the second area 112 to form a first sub-area 1121 , a second sub-area 1122 , a third sub-area 1123 and a fourth sub-area 1124 ;
[0075] The areas of the first sub-region 1121 , the second sub-region 1122 , the third sub-region 1123 and the fourth sub-region 1124 are different.
[0076] The shielding plate 11 has a quadrilateral structure. The first region 111 includes four edges parallel to the four edges of the shielding plate 11. These four edges form the basic framework of the first region 111, with adjacent edges smoothly connected by arcs. The extensions of the adjacent edges and the arcs enclose four subregions in the second region 112: a first subregion 1121, a second subregion 1122, a third subregion 1123, and a fourth subregion 1124. These four subregions are unequal in area. By reserving subregions of varying sizes at the four corners of the first region 111, the center of mass of the first region 111 of each shielding plate 11 is offset from the center of the shielding plate 11. When multiple shielding plates 11 are assembled into the shielding unit 10, the center points of the first regions 111 of each layer of shielding plates 11 are also staggered. This ensures that the perforations of each shielding plate 11 do not overlap, preventing through-holes from forming in the shielding unit 10.
