Description

Technical Field

[0001] This utility model relates to the field of flexible lead curtain technology, and more specifically, to a flexible lead curtain for radiation protection. Background Technology

[0002] Flexible lead curtains for radiation protection are specially designed protective devices to block and reduce radiation. They primarily utilize the high density of lead to shield against ionizing radiation, such as X-rays and gamma rays. Lead has excellent absorption and attenuation properties for radiation, effectively reducing the harm of radiation to the human body and sensitive equipment.

[0003] While existing flexible lead curtains for radiation protection can be bent and folded, excessive bending or prolonged twisting can cause local deformation of the lead core, resulting in low resilience and a tendency to deform and fail to return to a flat state. This deformation reduces the lead equivalent in local areas, thus affecting the overall radiation shielding effect. Therefore, we propose a flexible lead curtain for radiation protection. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a flexible lead curtain for radiation protection, so as to solve the technical problem that the current flexible lead curtain has local deformation when repeatedly bent or in a long-term twisted state, which leads to a reduction in the radiation protection effect in local areas.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a flexible lead curtain for radiation protection, comprising a soft lead curtain body composed of a first outer layer and a second outer layer, wherein a plurality of shielding layers are wrapped between the first outer layer and the second outer layer, and a rebound plate is sandwiched in the middle of the plurality of shielding layers;

[0006] The opposite sides of the rebound plate are provided with a number of annular grooves, and the side of the rebound plate located inside the annular grooves is provided with a diamond-shaped groove.

[0007] This invention enhances overall resilience by incorporating a spring plate structure between several shielding layers. The spring plate's properties allow the shielding layer to quickly flatten after bending, while also strengthening its resistance to bending. This reduces the probability of localized deformation caused by excessive bending, thus maintaining good radiation protection.

[0008] Preferably, the opposite sides of the first outer layer and the second outer layer are both extruded and formed with grooves, and the grooves are square in shape, with the same size as the shielding layer and the rebound plate.

[0009] Preferably, a metal ring is fixedly provided inside the perforation and is fixedly connected to the outer walls of the first outer layer and the second outer layer, and the diameter of the metal ring is larger than the diameter of the perforation.

[0010] Preferably, the first outer layer and the second outer layer are made of a multi-layer composite of vinyl and striped mesh fabric.

[0011] Preferably, the shielding layer is made of lead plate, and the shielding layer has at least eight layers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model enhances the overall resilience by setting a spring plate structure between several shielding layers. The characteristics of the spring plate allow the shielding layer to quickly flatten after being bent, and also enhance the bending resistance of the shielding layer. In this way, the probability of local deformation caused by excessive bending can be reduced under the action of the spring plate, thus maintaining a good radiation protection effect.

[0014] 2. This utility model also disperses concentrated stress in the circumferential direction by opening annular grooves on both sides of the rebound plate, thereby improving the uniformity of stress at the bending position and thus improving the rebound effect at the bending position. The addition of diamond grooves allows the rebound plate to resist deformation in multiple directions, thereby further improving the resilience of the rebound plate and enhancing the protection effect of the shielding layer. At the same time, this structural design can reduce the weight of the rebound plate and reduce the impact on the overall weight of the soft lead curtain body. Attached Figure Description

[0021] like Figures 1 to 5 As shown, this utility model relates to a flexible lead curtain for radiation protection, comprising a soft lead curtain body 1 composed of a first outer layer 101 and a second outer layer 102. A plurality of shielding layers 2 are wrapped between the first outer layer 101 and the second outer layer 102, and a spring plate 3 is sandwiched in the middle of the plurality of shielding layers 2. The arrangement of the first outer layer 101 and the second outer layer 102 can seal and wrap the plurality of shielding layers 2 inside, thereby playing a protective role. The spring plate 3 is located in the middle of the plurality of shielding layers 2, thereby playing an elastic support role. This increases the rebound force after bending the soft lead curtain body 1, and plays an elastic support role for the plurality of shielding layers 2, so that the shielding layers 2 are not easily deformed after repeated bending.

[0022] The opposite sides of the spring plate 3 are provided with a number of annular grooves 301, and the side of the spring plate 3 located inside the annular grooves 301 is provided with diamond grooves 302. The annular grooves 301 can improve the uniformity of the force at the bending position when it is bent, reduce the influence of the bending force on the spring plate 3, and make it easier for the spring plate 3 to recover. The diamond grooves 302, together with this complex stress distribution, enable the spring plate 3 to resist deformation in multiple directions, enhance the bending deformation resistance of the spring plate 3, and further improve the deformation resistance of the shielding layer 2.

[0023] In the embodiments of this utility model, the opposite sides of the first outer layer 101 and the second outer layer 102 are both extruded and formed with grooves 103, and the shape of the grooves 103 is square. The size of the grooves 103 is the same as the size of the shielding layer 2 and the spring plate 3. The grooves 103 can increase the marking area and play a role in warning of danger. The outer edges of the first outer layer 101 and the second outer layer 102 protruding from the grooves 103 can be used for installation and fixing operations without affecting the integrity of the shielding layer 2.

[0024] In the embodiments of this utility model, the first outer layer 101 and the second outer layer 102 are provided with corresponding perforations 104 on the side of the groove 103, and adjacent perforations 104 are arranged at equal intervals; the perforations 104 can increase the number of installation and positioning positions.

[0025] In an embodiment of this utility model, a metal ring 105 is fixedly provided inside the perforation 104 and is fixedly connected to the outer wall of the first outer layer 101 and the second outer layer 102, and the diameter of the metal ring 105 is larger than the diameter of the perforation 104; the provision of the metal ring 105 can strengthen the strength of the perforation 104, improve the protection of the outer side of the soft lead curtain body 1, and reduce the occurrence of damage.

[0026] In the embodiments of this utility model, the first outer layer 101 and the second outer layer 102 are made of a multi-layer composite of vinyl and striped mesh fabric; it has good flexibility, chemical corrosion resistance and a certain strength.

[0027] In this embodiment of the invention, the shielding layer 2 is made of lead plate, and the shielding layer 2 has at least eight layers; the most important performance of the lead plate is its shielding effect against radiation. Its ability to absorb and attenuate radiation is related to the thickness of the lead plate. Generally speaking, the thicker the lead plate, the better the shielding effect against radiation.

[0028] Working Principle: This embodiment provides a flexible lead curtain for radiation protection. By setting a rebound plate 3 between several shielding layers 2, the overall toughness can be increased. When bending the main body 1 of the flexible lead curtain, the support of the rebound plate 3 can improve the uniformity of the stress on the shielding layer 2. Thus, when the pressure on the main body 1 of the flexible lead curtain is released, the force of the rebound plate 3 can improve the resilience of the shielding layer 2, achieving the effect of quickly returning to a flat state. Therefore, when the main body 1 of the flexible lead curtain is repeatedly bent, the shielding layer 2 is less likely to deform locally. The annular grooves 301 opened on both sides of the rebound plate 3 can improve the uniformity of the stress at the bending position. The annular grooves 301 can adjust the elastic modulus distribution inside the thin plate to a certain extent. As the stress is redistributed around the groove, the elastic modulus of the rebound plate 3 is relatively lower in the area near the annular groove 301, and relatively higher in the area away from the groove. This change allows the elastic deformation of the soft lead curtain body 1 to be more evenly distributed across the entire body 1 when subjected to external force, thus improving the rebound and recovery effect. The diamond-shaped grooves 302 structure within the annular groove 301 form a cross-stress distribution network on the rebound plate 3. When the rebound plate 3 is subjected to external force, the four corners and four sides of the diamond-shaped grooves 302 will generate stresses in different directions. This complex stress distribution enables the rebound plate 3 to resist deformation in multiple directions. Moreover, the geometric parameters such as the angle and side length of the diamond-shaped grooves 302 can adjust the magnitude and direction of the stress, further improving the resistance to deformation. This strengthens the protection of the shielding layer 2, allowing it to maintain flatness and prevent localized deformation when subjected to repeated bending.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
