Description

Technical Field

[0001] This utility model relates to the field of radiation protection technology, specifically a high-dose protective container. Background Technology

[0002] To ensure personnel and environmental safety, a series of regulations and standards have been formulated both domestically and internationally, and clear provisions have been made regarding radiation dose limits for the use, transportation, and storage of radioactive materials. This requires the use of standard-compliant protective equipment in all operations involving radioactive materials, and high-dose protective containers are one of the important protective equipment.

[0003] High-dose protective containers are used to store and transport highly radioactive materials. However, with the increase in the number of uses and the vibration, bumps and collisions during transportation, the sealing structure of the container, such as rubber gaskets and welded joints, is prone to loosening, affecting the sealing effect. Therefore, we propose a high-dose protective container. Utility Model Content

[0004] The purpose of this invention is to provide a high-dose protective canister to solve the problem mentioned in the background art that, with the increase in the number of uses and the vibration, bumps, and collisions during transportation, the sealing structure of the canister, such as rubber gaskets and welded joints, is prone to loosening, affecting the sealing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-dose protective container, comprising a protective container, wherein the exterior of the protective container is provided with a multi-layer shielding assembly, and the top of the multi-layer shielding assembly is provided with a sealing and fixing assembly; The multi-layer shielding assembly includes a shielding shell, a shielding layer fixedly installed on the inner wall of the shielding shell, a positioning frame slidably connected to the shielding layer through a groove provided inside it, a second reflective layer fixedly installed on one side of the positioning frame, a second reflective layer slidably connected inside the shielding layer, and bolts threadedly connected to both the second reflective layer and the shielding layer through threaded holes provided inside them, with a limit shielding cylinder connected to the external threads of the bolts.

[0006] The limiting shielding cylinder is fixed to the second reflective layer by bolts, and a protective tank is installed inside the limiting shielding cylinder.

[0007] The sealing and fixing assembly includes a shielding cover, with a shielding cover on the top of the shielding shell and a sealing ring fixedly installed at the bottom of the shielding cover.

[0008] The sealing ring is the same size as the opening of the second reflective layer, and the first reflective layer is fixedly installed at the bottom of the shielding cover. The outer side of the first reflective layer is in contact with the inner wall of the sealing ring.

[0009] The shielding cover has multiple hinge blocks on its exterior. A spring is fixedly installed at the bottom of each hinge block, a mounting bracket is fixedly installed at the bottom of each spring, and a spring pin is provided at the top of the mounting bracket.

[0010] The shielding shell is externally fixed with multiple blocking frames, and the blocking frames have multiple through holes inside. The mounting frame is engaged with the blocking frame by spring pins.

[0011] This utility model has at least the following beneficial effects: The protective container is sealed once by a set of sealing and fixing components, thus ensuring the sealing of the protective container during transportation. The set of multi-layer shielding components reflects and scatters the radiation leaking from the protective container multiple times during transportation, thereby reducing the penetration of the radiation and preventing the radiation from leaking out during the transportation of the protective container. After the radioactive material inside the protective container is cleaned, the limiting shielding cylinder can be removed by turning the bolts and the second reflective layer can be moved upward to remove and replace it or the radiation on its surface can be cleaned, so as to facilitate the next use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 The present invention provides a technical solution: a high-dose protective canister, including a protective canister 1, the exterior of which is provided with a multi-layer shielding assembly 3, and the top of the multi-layer shielding assembly 3 is provided with a sealing and fixing assembly 2; The multi-layer shielding assembly 3 includes a shielding shell 36, a shielding layer 35 fixedly installed on the inner wall of the shielding shell 36, a positioning frame 34 slidably connected to the shielding layer 35 through a groove provided inside it, a second reflective layer 33 fixedly installed on one side of the positioning frame 34, the second reflective layer 33 slidably connected inside the shielding layer 35, the second reflective layer 33 and the shielding layer 35 are both threadedly connected to bolts 31 through threaded holes provided inside them, a limiting shielding cylinder 32 is threadedly connected to the outside of the bolts 31, the limiting shielding cylinder 32 is fixed to the second reflective layer 33 by the bolts 31, and a protective canister 1 is provided inside the limiting shielding cylinder 32.

[0017] The sealing and fixing assembly 2 includes a shielding cover 21. The shielding cover 21 is provided on the top of the shielding shell 36. A sealing ring 27 is fixedly installed on the bottom of the shielding cover 21. The size of the sealing ring 27 is the same as the size of the opening of the second reflective layer 33. A first reflective layer 26 is fixedly installed on the bottom of the shielding cover 21. The outer side of the first reflective layer 26 is in contact with the inner wall of the sealing ring 27. Multiple hinge blocks 22 are hinged to the outside of the shielding cover 21. A spring 23 is fixedly installed on the bottom of the hinge block 22. A mounting bracket 24 is fixedly installed on the bottom end of the spring 23. A spring pin 28 is provided on the top of the mounting bracket 24. Multiple blocking brackets 25 are fixedly installed on the outside of the shielding shell 36. Multiple through holes are provided inside the blocking brackets 25. The mounting bracket 24 is engaged with the blocking bracket 25 by the spring pin 28.

[0018] When it is necessary to clean and transport the radioactive material inside the protective container 1, first place the protective container 1 into the shielding shell 36 and position it inside the limiting shielding cylinder 32. Then, cover it with the shielding cover 21 and pull the mounting bracket 24 so that its top surface contacts the bottom of the blocking bracket 25. At this time, the spring 23 extends and retracts, and the hinge block 22 moves. After hearing the spring pin 28 engage with the blocking bracket 25, release the mounting bracket 24. Then, operate the remaining mounting bracket 24 in the same way as before, so that the shielding cover 21 is fixed to the shielding shell 36. At this time, the sealing ring 27 is located on the inner wall of the second reflective layer 33, thus completing the seal.

[0019] During the transportation of the protective container 1, the radiation energy of the radioactive material inside may increase. As the number of times the protective container 1 is used increases, it becomes difficult to completely shield the radioactive material inside. The first reflective layer 26 and the second reflective layer 33 are set here so that the radiation leaking from the protective container 1 is reflected and scattered multiple times inside the container, thereby reducing the penetration of the radiation. At this time, some radiation may still break through the first reflective layer 26 and the second reflective layer 33. Therefore, the shielding layer 35, the shielding shell 36 and the shielding cover 21 can block this part of the radiation to prevent radiation leakage during the transportation of the protective container 1. After the radioactive material inside the protective container 1 is cleaned, the limiting shielding cylinder 32 can be removed by rotating the bolt 31 and the second reflective layer 33 can be moved upward to remove it for replacement or its surface can be cleaned of radiation, so as to facilitate the next use.
