Description

Technical Field

[0001] This utility model belongs to the field of protective materials, specifically a lead-free protective barium plate. Background Technology

[0002] In fields such as medical and industrial flaw detection, radiation protection for personnel and equipment is often required. Traditional protective materials often use lead-containing materials. Lead has good radiation shielding performance. However, lead is a heavy metal and poses potential hazards to the environment and human health. During production, use and disposal, lead may leak into the environment, polluting soil and water sources. Furthermore, once ingested by humans, lead can cause serious damage to the nervous system, blood system and other systems. In addition, existing protective panels are large in size and inconvenient to transport. Therefore, we designed a lead-free protective barium plate that can be quickly spliced ​​and installed.

[0004] This utility model is achieved through the following technical solution:

[0005] A lead-free protective barium plate includes a substrate, on both sides of which a barium-based protective layer is fixedly disposed. On both sides of the substrate and the barium-based protective layer, a connecting block is fixedly disposed to fix the three together. The connecting block is an isosceles triangular structure. The connecting block is provided with a slot and a strip. The slot and strip on both sides are arranged oppositely, and the strip can be inserted into the corresponding slot.

[0006] As described above, a lead-free protective barium plate is provided, wherein the barium-based protective layer is made of at least one of barium sulfate, barium oxide, or barium titanate, accounting for 70-90 wt%, mixed with a polymer binder.

[0007] As described above, in a lead-free protective barium plate, several evenly distributed rubber pads are fixedly provided on the bottom side of the barium-based protective layer.

[0008] As described above, in a lead-free protective barium plate, the substrate is a high-strength fiber material, such as carbon fiber or glass fiber.

[0009] In the lead-free protective barium plate described above, the top end of the slot and the bottom end of the strip are respectively configured as spherical structures.

[0010] As described above, in a lead-free protective barium plate, several insertion rods are fixedly provided on the front side of the substrate, and several insertion holes are provided on the rear side of the substrate corresponding to the insertion rods, so that the insertion rods can be inserted and engaged with the corresponding insertion holes.

[0011] The advantages of this utility model are: it has a simple structure and ingenious design. By using lead-free barium-based protective materials, it avoids the harm of lead to the environment and human body, meeting the requirements of green environmental protection and occupational health and safety. The barium compounds in the barium-based protective layer have good absorption and scattering effects on radiation, effectively blocking common radiations such as X-rays and gamma rays. Its protective performance is comparable to traditional lead-containing protective materials. In addition, multiple barium plates can be spliced ​​together to form a protective plate or a storage box for use, offering diverse functions. At the same time, the small size of the barium plates facilitates transportation, meets market demand, and is suitable for promotion. Attached Figure Description

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

[0016] A type of lead-free protective barium plate, such as Figure 1 , 2As shown in Figures 3 and 4, the substrate includes a base plate 1. A barium-based protective layer 2 is fixedly provided on both sides of the base plate 1. A connecting block 3 that can fix the three together is fixedly provided on both sides of the base plate 1 and the barium-based protective layer 2. The connecting block 3 has an isosceles triangular structure. A slot 4 and a strip 5 are respectively provided on the connecting block 3. The slots 4 and strips 5 on both sides are arranged oppositely. The slot 4 on the left side is below the strip 5, and the slot 4 on the right side is above the strip 5. The strip 5 can be inserted into the corresponding slot 4.

[0017] Specifically, as shown in the figure, the barium-based protective layer 2 in this embodiment is made of at least one of barium sulfate, barium oxide, or barium titanate, accounting for 70-90 wt%, mixed with a polymer binder. Barium compounds such as barium sulfate have good radiation absorption capabilities, while the polymer binder firmly bonds the barium compounds together and tightly bonds them to the substrate 1.

[0018] Specifically, as shown in the figure, the bottom side of the barium-based protective layer 2 in this embodiment is fixed with several evenly distributed rubber pads 30. In this embodiment, there are four rubber pads 30. When transporting barium plates, several barium plates can be stacked together for transport. The rubber pads 30 can prevent the barium-based protective layer 2 from sliding and scratching each other during transportation.

[0019] Furthermore, as shown in the figure, the substrate 1 in this embodiment is a high-strength fiber material, such as carbon fiber or glass fiber. This provides structural support for the entire barium plate, ensuring that the barium plate has sufficient strength and toughness, and is not easily broken.

[0020] Furthermore, as shown in the figure, the top end of the card slot 4 and the bottom end of the card strip 5 in this embodiment are respectively set as spherical structures, with a larger end size of the spherical structure. The spherical structure can make the card strip 5 and the card slot 4 fit more firmly, preventing the card strip 5 from easily sliding out of the card slot 4.

[0021] Furthermore, as shown in the figure, the front side of the substrate 1 in this embodiment is fixedly provided with several insertion rods 60, and the rear side of the substrate 1 is provided with several insertion holes 61 corresponding to the insertion rods 60. The insertion rods 60 can be inserted and engaged with the corresponding insertion holes 61. Inserting the insertion rods 60 of the first barium plate into the insertion holes 61 of the second barium plate on the front side completes the splicing of the two barium plates, which can increase the stability of the protective barium plate.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
