Description

Technical Field

[0001] The utility model relates to the technical field of radiation shielding, in particular to a radiation safety protection device with multi-level shielding. Background Art

[0002] With the rapid development of nuclear science and technology and the widespread application of nuclear reactions in many fields such as medicine, scientific research, and industry, the issue of radiation safety protection has become increasingly prominent. Existing radiation safety protection equipment is often relatively simple in material selection, and mostly relies on traditional shielding materials such as lead. However, although lead materials have a certain ability to absorb radiation, they are dense, easy to corrode, and have limited shielding effects on high-energy rays (such as X-rays and gamma rays). Especially in complex radiation environments, their protection effects are often unsatisfactory. Utility Model Content

[0003] The purpose of the utility model is to provide a radiation safety protection device with multi-level shielding, so as to solve the problem of relatively single material selection of existing radiation safety protection devices mentioned in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A radiation safety protection device with multi-level shielding, comprising a safety protection outer cover for shielding radiation, wherein the inner wall of the safety protection outer cover is embedded with a tungsten alloy shielding layer and a composite material shielding layer, and the top of the safety protection outer cover is an open structure and a shielding top cover is installed on the top;

[0006] The safety protection outer cover is a top-open and hollow columnar structure, and a first embedding groove and a second embedding groove for installing a tungsten alloy shielding layer and a composite material shielding layer are respectively formed on the top edge of the safety protection outer cover.

[0007] Preferably, a shielding inner cover is provided on the inner wall of the safety protection outer cover.

[0008] Preferably, the thickness of the shielding inner cover is 3-5 mm, the shielding inner cover is made of stainless steel and is an integrally formed structure with the inner wall of the safety protection outer cover.

[0010] Preferably, the width of the first embedding groove is the same as the thickness of the tungsten alloy shielding layer, and both are 2-5 mm.

[0011] Preferably, the width of the second embedding groove is the same as the thickness of the composite material shielding layer, and both are 3-6 mm.

[0013] Preferably, a transparent observation window is provided at the center of the top surface of the shielding top cover.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In this multi-level shielding radiation safety protection device, the tungsten alloy shielding layer is known for its high density and good radiation absorption ability. As the first layer of shielding material on the inner wall of the safety protection cover, it can effectively block and absorb various radiation particles from the outside, including X-rays, gamma rays, etc., thereby significantly reducing the probability of radiation penetrating into the internal space and ensuring the safety of internal items. The embedding of the composite shielding layer and its location behind the tungsten alloy shielding layer further enhances the protection ability against different types of radiation, which not only improves the broad spectrum of the overall shielding effect, but also effectively copes with mixed radiation sources in complex environments, providing more comprehensive and detailed radiation protection. The safety protection cover adopts a top opening design, which is convenient for placing items. At the same time, the shielding cover installed on the top is seamlessly connected to form a complete protection system. The shielding cover also has excellent radiation shielding performance, ensuring that there is no radiation leakage at the top opening and maintaining the consistency of the overall protection level. The first embedding groove and the second embedding groove opened on the top edge of the safety protection cover are specially tailored for the tungsten alloy shielding layer and the composite shielding layer, which not only simplifies the installation process and improves the assembly accuracy, but also ensures the close combination between the shielding layer and the protective cover.

[0016] 2. In the present multi-level shielding radiation safety protection device, a number of ejection holes are evenly and equidistantly arranged in a ring shape and corresponding to the positions of the first embedding groove and the second embedding groove are opened at the bottom of the safety protection outer cover, so as to facilitate ejecting or installing the shielding layer from the bottom when necessary, such as for maintenance, replacement or adjustment, thereby improving the maintainability and flexibility of the protection device and reducing maintenance time and cost.

[0017] 3. In this multi-level shielding radiation safety protection device, a transparent observation window is set at the center of the top surface of the shielding top cover, through which the internal situation can be observed, which improves the convenience and practicality of use. At the same time, the transparent observation window is also made of radiation-proof material to ensure that there is no damage from radiation during the observation process.

The shielding material can effectively block and absorb various radiation particles from the outside, including X-rays, gamma rays, etc., thereby significantly reducing the probability of radiation penetrating into the internal space and ensuring the safety of the internal items. The composite shielding layer 30 is embedded and located behind the tungsten alloy shielding layer 20, further enhancing the protection ability against different types of radiation, not only improving the broad spectrum of the overall shielding effect, but also effectively dealing with mixed radiation sources in complex environments, providing more comprehensive and detailed radiation protection. The safety protection cover 10 adopts a top opening design, which is convenient for placing items. At the same time, the shielding top cover 40 installed on the top is seamlessly connected to form a complete protection system. The shielding top cover 40 also has excellent radiation shielding performance, ensuring that there is no radiation leakage at the top opening and maintaining the consistency of the overall protection level. The first embedding groove 12 and the second embedding groove 13 opened at the top edge of the safety protection cover 10 are specially tailored for the tungsten alloy shielding layer 20 and the composite shielding layer 30, which not only simplifies the installation process and improves the assembly accuracy, but also ensures the close combination between the shielding layer and the protective cover.

[0030] Furthermore, a shielding inner cover 11 is provided on the inner wall of the safety protection outer cover 10. The thickness of the shielding inner cover 11 is 3-5 mm. The shielding inner cover 11 is made of stainless steel and is an integrally formed structure with the inner wall of the safety protection outer cover 10 to provide an additional radiation shielding layer. The choice of stainless steel ensures the corrosion resistance and durability of the shielding inner cover 11, and is suitable for a variety of harsh working environments.

[0031] Specifically, the bottom of the safety protection cover 10 is provided with a plurality of ejection holes 14 which are evenly and equidistantly arranged in a ring shape and correspond to the positions of the first embedding groove 12 and the second embedding groove 13, so as to facilitate ejecting or installing the shielding layer from the bottom when necessary, such as for maintenance, replacement or adjustment, thereby improving the maintainability and flexibility of the protective device and reducing maintenance time and cost.

[0032] Among them, the width of the first embedded groove 12 is the same as the thickness of the tungsten alloy shielding layer 20, and both are 2-5mm.

The composite shielding layer 30 is aligned with the second embedding groove 13, and also uses tools to assist, and pushes it smoothly and fits tightly to the tungsten alloy shielding layer 20. Then, the shielding top cover 40 is aligned with the top opening of the safety protection outer cover 10 to ensure that all edges are aligned. After completing all installation steps, a comprehensive inspection of the entire safety protection device is carried out, including the installation quality of each shielding layer, the sealing of the seams, and the stability of the overall structure.
