DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0020] Please refer to Figures 1-5The utility model provides a technical scheme: a sealed door for nuclear radiation protection, including fixed frame 1, the outer side of the front and back of fixed frame 1 is fixedly installed with reinforcing plate 2, the front of fixed frame 1 is provided with a plurality of first protective lead curtain 3, the back of fixed frame 1 is provided with a plurality of second protective lead curtain 5, the both sides of fixed frame 1 inner wall are fixedly installed with a plurality of hinges 12 through bolt, the other end of hinge 12 is fixedly installed with protective door 6, the outer side of protective door 6 is fixedly installed with sealing strip 7, the back of one of protective door 6 is fixedly installed with rotating rod 9, the outer side of rotating rod 9 is movably installed with baffle 10, the end away from rotating rod 9 of baffle 10 is fixedly installed with handle 11, the back of another of protective door 6 is fixedly installed with a plurality of branch frame 8, the top of fixed frame 1 is provided with a plurality of protective concrete brick 4, the top of fixed frame 1 inner chamber is fixedly installed with ring pipe 13, the bottom of ring pipe 13 is communicated with a plurality of shower head 14, the top of ring pipe 13 is communicated with water delivery pipe 15, the other end of water delivery pipe 15 is communicated with small water pump 16, protective door 6 includes sealed shell 601, the inner side of sealed shell 601 is fixedly installed with lead plate interlayer 602, the inner side of lead plate interlayer 602 is fixedly installed with additive concrete 603.
[0021] The working principle of the above technical scheme is as follows: when the structure is used, first, the fixed frame 1 and the reinforcing plate 2 are installed on the wall position, and the protective concrete bricks 4 are inserted into the gaps to reduce the space gaps and assist in correcting the installation position. After the erection is completed, the first protective lead curtain 3 is used to perform the first protection against external radiation. Then, the multi-layer structure of the protective door 6 blocks. First, the sealed shell 601 attenuates the radiation to a certain extent, forming the first line of defense against radiation. Then, the lead plate interlayer 602 further attenuates the energy of the radiation. After that, the radiation is absorbed and scattered to a certain extent. Finally, the radiation is completely attenuated by the double-layer lead plate interlayer 602 and the sealed shell 601, and the gap when the protective door 6 is opened is sealed by the soft sealing action of the sealing strip 7. At the same time of sealing, the sealing strip 7 blocks the excess radiation. Finally, the second protective lead curtain 5 completely blocks the radiation, avoiding the passage of radiation and increasing safety. The structure design increases the application in different application scenarios, enabling the use in various protection-required situations, reducing limitations, and increasing protection effectiveness.
[0022] In another embodiment, as shown in Figure 1 and Figure 2 , the first protective lead curtain 3 and the second protective lead curtain 5 are linearly and uniformly distributed on the outer side of the reinforcing plate 2. The top ends of the first protective lead curtain 3 and the second protective lead curtain 5 are fixed on the outer side of the reinforcing plate 2 by bolts.
[0023] The first protective lead curtain 3 and the second protective lead curtain 5 serve as the first line of defense on the outer side, facilitating the increase of protection effectiveness, the stability of protection performance, and the convenience of replacement and disassembly.
[0024] In another embodiment, as shown in Figures 1-5 The hinges 12 are linearly and uniformly distributed on the opposite side of the fixed frame 1 and the protective door 6, the sealing strip 7 is matched with the size of the protective door 6, and the sealing strip 7 is made of boron polyethylene.
[0025] The hinges 12 provide opening and closing installation support for the protective door 6, and seal the gaps between the protective door 6 and the fixed frame 1 through the sealing strip 7, so as to seal while reducing the leakage of radiation. The boron element has a large absorption cross section for neutrons. After the collision between the neutron and the boron nucleus, the neutron is absorbed by the boron nucleus, thereby reducing the neutron radiation. The boron polyethylene is a composite material made by adding boron powder to polyethylene. The polyethylene itself also has certain radiation resistance, and its good forming performance can be easily made into various protective shapes.
[0026] In another embodiment, as shown in Figure 4 and Figure 5 The support frame 8 is linearly and uniformly distributed on the back of the protective door 6, the baffle 10 is matched with the size of the baffle 10, and the top of the support frame 8 is open.
[0027] The support frame 8 provides blocking and support for the baffle 10. The structure is simple, easy to maintain, convenient to use, avoids complex operation, and increases the convenience of using the structure.
[0028] In another embodiment, as shown in Figures 1-5 The protective concrete bricks 4 are linearly and uniformly distributed in a rectangular shape on the opposite side of the fixed frame 1 and the reinforcing plate 2, the spray head 14 is linearly and uniformly distributed at the bottom of the ring pipe 13, the water pipe 15 penetrates the fixed frame 1, passes through the protective door 6 and extends to the inside of the back of the fixed frame 1, and the small water pump 16 is fixedly installed at the top of the inner cavity of the fixed frame 1.
[0029] The fixed frame 1 and the reinforcing plate 2 are installed in the wall position, and the protective concrete bricks 4 are inserted into the gap to reduce the space gap and assist in correcting the installation position. In this scheme, the small water pump 16 is not punched in the inside position of the fixed frame 1. When it is necessary to go out to reduce the adhesion of radiation dust, the small water pump 16 is connected to the water source, the water flow is pumped to the water pipe 15, and then to the inside of the ring pipe 13 through the water pipe 15. The water is sprayed on the outside of the protective door 6 through the ring pipe 13 and the spray head 14, so as to wash away the dust and other residues, increase the safety, and facilitate the reduction of radiation in special environments, thereby increasing the protection and safety.
[0030] In another embodiment, as shown in Figures 3-5As shown, the lead plate interlayer 602 is located on the front and back of the additive concrete 603, the sealing shell 601 is wrapped outside the lead plate interlayer 602 and the additive concrete 603, the material of the sealing shell 601 is iron, and the additive concrete 603 is high-density concrete added with heavy aggregate.
[0031] The sealing shell 601 is made of iron, which can attenuate the rays to a certain extent. When the rays propagate in the iron, they will interact with the electrons and atomic nuclei of the iron atoms, and lose energy through ionization and excitation processes. However, the iron provides high strength and good mechanical properties for the overall structure. The lead material of the lead plate interlayer 602 has good absorption capacity for rays, and can effectively block X-rays, gamma rays, etc. This is because when the ray particles interact with the lead atoms, they will transfer the energy of the rays to the lead atoms through photoelectric effect, Compton effect and electron pair effect, thereby weakening the intensity of the rays. The concrete material of the additive concrete 603 is added with heavy density materials such as barite and iron ore. The heavy elements in the concrete, such as calcium and silicon, can absorb and scatter rays to a certain extent. The concrete added with heavy aggregate such as barite and iron ore serves as a shielding structure to block the radiation generated by the radiation source. The overall structure further increases the protection performance and improves the use in different radiation protection scenarios, reducing the limitations.
[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application. The scope of the present application is defined by the appended claims and their equivalents.
