Description

Technical Field

[0001] This utility model relates to the field of radiation protection box technology, and in particular to a nuclear radiation protection box. Background Technology

[0002] Nuclear radiation protection boxes are specialized equipment designed for the safe storage, transportation, and handling of radioactive materials. Their core function is to shield and absorb nuclear radiation using high-density materials. These boxes are indispensable in the nuclear industry and medical fields, primarily serving to store and isolate radioactive materials to protect personnel and the environment from the effects of nuclear radiation. Through the use of special materials and designs, these boxes effectively block the radiation of radioactive materials, ensuring the safe storage and handling of such materials.

[0003] Utility model patent CN219392970U discloses a nuclear radiation protection box, belonging to the field of radiation protection boxes. This box has a lid rotatably connected to its upper part, and two sets of sliding frames symmetrically slidably connected inside. Lead plates are placed inside the box, and a pushing mechanism is provided on the side of the box to push the lead plates onto the sliding frames. When the lid is closed, the pushing mechanism pushes the lead plates inside the box onto the two sliding frames inside the box. At this time, the two sliding frames support the lead plates. Therefore, when the lid is opened again to place nuclear waste, the lead plate at the top can block the radiation emitted by the nuclear waste below. When the lid is closed, the lead plate at the top descends, and the lead plates inside the box are pushed back onto the sliding frames inside the box. This cycle continues, ensuring that users are not exposed to radiation from previously placed nuclear waste when disposing of it, thus improving safety.

[0004] However, the internal structure of the aforementioned protective boxes is relatively complex, increasing manufacturing costs and making them inconvenient to use. Moreover, some existing radiation protection boxes generally have lead plate materials for their internal interlayer, making them heavy and difficult to transport, thus reducing their effectiveness. Therefore, we propose a nuclear radiation protection box to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a nuclear radiation protection box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

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

[0015] This device, with its stainless steel outer shell, stainless steel inner shell, and protective corner pads, increases the overall rigidity and protective effect of the protective enclosure, facilitating stable use. Furthermore, the novel composite material with lead-boron-polyethylene layers combines lead's shielding ability against gamma rays with boron's high absorption cross-section for neutrons, effectively enhancing radiation protection while being lighter and more portable. The built-in boxes and doors allow for the separate storage of radioactive materials, facilitating the categorized and spaced collection of these materials by staff, resulting in excellent performance.

The bottom end of each limiting sliding rod 15 passes through the support spring 14 and the limiting sliding hole 13 in sequence and extends to the bottom of the support frame 12. Through the cooperation of the limiting sliding rod 15, the limiting sliding hole 13 and the support spring 14, the placement plate 10 can be elastically supported, which facilitates the elastic and safe placement of radiation materials.

[0028] The inner wall of the built-in box 8 is fixedly connected with two sets of symmetrical protective pads 81. The protective pads 81 are rubber pads, which can increase the protection effect inside the built-in box 8 and facilitate the safe storage of radioactive materials. Each built-in door 9 has an opening and closing handle 91 fixedly connected to its upper surface. Each built-in door 9 has a lead glass frame 92 fixedly embedded in its upper surface, which can increase the observation function of this protective box and facilitate understanding of the storage of radioactive materials.

[0030] The working principle of this utility model is as follows:

[0031] In use, the staff first moves the protective box to the radiation material storage area using the stainless steel handle 5 and anti-slip sleeve 51. Then, they move the latch 7 to open the sealed door 2 and simultaneously open one of the inner doors 9 using the opening and closing handle 91. The radiation material is then placed on the placement plate 10 inside the inner box 8. The inner door 9 and the sealed door 2 are then closed, and the protective box is moved to another location. The sealed door 2 and the inner door 9 are opened in sequence to store other radiation materials. During storage, the stainless steel outer shell 101 and stainless steel inner shell 103 increase the overall rigidity of the protective box 1. The lead-boron polyethylene layer 102 composite material combines the shielding ability of lead against gamma rays with the high absorption cross section of boron against neutrons, effectively shielding both neutrons and gamma rays, thus achieving effective radiation protection for this protective box.
