Description

Technical Field

[0001] The utility model relates to the technical field of shielding bricks, in particular to a shielding brick for a particle therapy radiation protection building. Background Art

[0002] Particle therapy, also known as heavy ion therapy or proton therapy, is a tumor treatment method that uses high-energy particles to perform targeted radiation therapy on tumors. The therapeutic rays of high-energy particle radiotherapy have strong penetrating power. Without proper shielding protection measures, it may cause radiation risks to equipment operators, patients and other personnel. Shielding bricks have excellent blocking ability and can effectively reduce radiation leakage during treatment, thereby protecting personnel from radiation damage.

[0003] After searching, the Chinese authorized patent number CN207988323U authorized the disclosure of a pre-assembled radiation protection building shielding brick, shielding module component and building system, including: pre-assembled radiation protection building shielding bricks with multiple curved end faces, pre-assembled radiation protection building shielding module components using pre-assembled radiation protection building shielding bricks; and pre-assembled radiation protection building system using pre-assembled radiation protection building shielding module components. Shielding bricks can be directly spliced, and there are no problems such as heating and cracking of large concrete pouring. The uniform element ratio of shielding bricks in the factory overcomes the inconsistency of concrete elements in different regions. The pipelines of the building system are connected to the shielding bricks in a pre-assembled component manner, and high-precision positioning of the pipeline interface becomes an easy-to-achieve effect. The shape design of each shielding module component can produce the most optimized shielding effect. The gap path through which radiation passes is a continuous differentiable function curve without any straight lines. After the equipment reaches its design life, the building is easy to dismantle.

[0004] However, it still has the following disadvantages in actual use:

[0005] The shielding brick is an integrated design, and only two sides have an uneven surface design, which reduces the shielding brick's shielding of radiation in different frequency bands, and reduces the reflection and scattering of radiation when passing through the shielding brick, thereby reducing the radiation blocking effect.

[0006] Therefore, a new shielding brick for particle therapy radiation protection building is proposed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a shielding brick for a particle therapy radiation protection building to solve the problem proposed in the above background technology that the shielding brick is an integrated design and only two sides adopt an uneven surface design, which reduces the shielding of radiation of different frequency bands by the shielding brick and reduces the reflection and scattering of radiation when passing through the shielding brick, thereby reducing the blocking effect of radiation.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a shielding brick for a particle therapy radiation protection building, comprising:

[0010] A main body component, the main body component includes a shielding brick, a square groove opened inside the shielding brick, a lower partition groove opened below the square groove, an upper partition groove opened above the square groove, a partition plate arranged outside the square groove, and a frame groove opened outside the lower partition groove and the upper partition groove;

[0011] The connecting component comprises a first square block arranged on the upper surface of the shielding brick.

[0012] Furthermore, the main body component also includes a groove arranged on the side wall of the outer surface of the shielding brick, and a protrusion arranged on the side wall of the outer surface of the shielding brick;

[0013] Specifically, the shielding brick has a multi-layer structure and a variety of materials inside, which can absorb radiation in different frequency bands, thereby improving the protective effect of the shielding brick.

[0014] Furthermore, there are two grooves, which are respectively arranged on the left and right side walls of the outer surface of the shielding brick, and there are two protrusions, which are respectively arranged on the sides of the two grooves;

[0015] Specifically, the two sides of the shielding brick adopt an uneven shape, which improves the reflection effect of the shielding brick on radiation.

[0016] Furthermore, the square groove is filled with graphite slurry, the lower groove is filled with copper blocks, the upper groove is filled with aluminum blocks, and the frame groove is filled with polymer gel;

[0017] Specifically, the graphite slurry inside the square groove is a mixture formed by graphite particles suspended in liquid. Graphite has good electrical conductivity and heat dissipation properties in the electromagnetic field and can be used to shield high-frequency radiation. The copper plate inside the lower partition groove can prevent the radiation of high-frequency electromagnetic waves. Aluminum is a lightweight metal used to shield high-frequency radiation. The polymer gel can form a uniform coating on the frame groove to shield radiation. At the same time, there is air inside the frame groove, which can increase the blocking effect on radiation. Air has certain absorption and scattering capabilities and can reduce the penetration of radiation.

[0018] Furthermore, the partition plate is made of steel and simultaneously separates the square slot, the lower partition slot, the upper partition slot and the frame slot;

[0019] Specifically, steel has high magnetic conductivity and can absorb low-frequency radiation.

[0020] Furthermore, the connection assembly also includes a first slot provided on the side wall of the first square block, a second square block provided on the lower surface of the shielding brick, and a second slot provided on the side wall of the second square block;

[0021] Specifically, there are five first square blocks and four first card slots, four second square blocks and three second card slots, and the upper and lower surfaces of the shielding brick are also designed with unevenness to improve the shielding brick's reflection effect on radiation.

[0022] Furthermore, five first square blocks are provided and equidistantly distributed on the upper surface of the shielding brick, four second square blocks are provided and equidistantly distributed on the lower surface of the shielding brick, and the first square blocks are engaged with the side walls of the second square blocks.

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The utility model can realize a multi-layer structural design of the shielding brick by arranging the square groove, the lower partition groove, the upper partition groove, the partition plate and the frame groove, and realize the shielding effect of radiation of different frequency bands by superposition and combination of different materials.

[0025] 2. Based on beneficial effect 1, by setting the first square block, the first slot, the second square block and the second slot, the outer surface of the shielding brick can be designed to be uneven, so that the radiation wave is reflected and scattered multiple times when passing through the shielding brick, thereby increasing the radiation blocking effect.
