Description

Technical Field

[0001] This utility model relates to the technical field of boron carbide polyethylene shielding plates, specifically a positioning device for boron carbide polyethylene shielding plates. Background Technology

[0002] Boron carbide polyethylene shielding panels are a type of high-efficiency radiation-shielding composite material, mainly used to block harmful radiation such as neutron rays and gamma rays. They are widely used in nuclear energy, medical, scientific research and other fields. Boron carbide (B4C) has an extremely strong neutron absorption capacity, which can convert neutrons into harmless nuclear reaction products. The hydrogen atoms in polyethylene can slow down gamma rays, and their energy is further attenuated by the thickness of the material.

[0003] The positioning device for boron carbide polyethylene shielding panels is an auxiliary structure or component used to fix, align, and maintain the position of the shielding panels, ensuring accurate positioning and long-term stability during installation. It typically uses threaded connections to fix the shielding panels to walls, frames, or equipment surfaces, providing high-strength support.

[0004] Existing boron carbide polyethylene shielding panels are installed using bolts and screws. When the bolts are tightened, local stress concentration occurs in the boron carbide polyethylene panel, causing the panel to deform or crack. Furthermore, bolt fixing requires drilling holes in the shielding panel, and the gaps in the holes affect the shielding effect. Therefore, there is a need for a positioning device that can quickly position the panel without damaging its structure, thereby improving the splicing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning device for boron carbide polyethylene shielding plates, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a positioning device for boron carbide polyethylene shielding plates, comprising:

[0007] The base plate, the first shielding plate, and the second shielding plate are provided. The first shielding plate is fixed on the base plate, and the second shielding plate is snapped onto the side wall of the first shielding plate. The base plate, the first shielding plate, and the second shielding plate are all made of boron carbide polyethylene.

[0008] The splicing assembly includes a fixed frame, a fixed shaft, a first retaining ring, and a first connecting plate. The fixed frame is attached to the surface of a first shielding plate, the fixed shaft passes through the middle of the fixed frame, the lower end of the first retaining ring passes through the outer surface of the fixed shaft and is located inside the fixed frame, and the first connecting plate is fixed to one side of the first retaining ring.

[0009] Furthermore, a first spring is fixed to the lower surface of the first connecting plate, and the lower surface of the first spring is fixed to the inner wall of the fixing frame.

[0010] Furthermore, a second retaining ring is rotatably passed through the middle of the outer surface of the fixed shaft, and a second connecting plate is fixed to the outside of the second retaining ring.

[0011] Furthermore, a second spring is fixed to one side of the outer surface of the second connecting plate, and one end of the second spring is fixed to the inner wall of the fixing frame.

[0012] Furthermore, the first retaining ring and the second retaining ring are internally engaged with retaining blocks, and a connecting block is fixed to one side of the retaining block, and one side of the connecting block is attached to the outer surface of the second shielding plate.

[0016] This utility model comprises a base plate, a first shielding plate, a second shielding plate, and a splicing assembly. When splicing the first and second shielding plates, the locking block is aligned with the first and second retaining rings. Under the connection of the first and second springs, a fixed shaft is fixedly connected to the first and second retaining rings, causing them to open outwards. The locking block then engages with the first and second retaining rings. At this point, the elastic force of the first and second springs causes the first and second retaining rings to tightly hold the locking block in place, thus positioning the first and second shielding plates.

[0026] 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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a positioning device for boron carbide polyethylene shielding plates, comprising:

[0029] The base plate 11, the first shielding plate 12 and the second shielding plate 13 are fixed on the base plate 11, and the second shielding plate 13 is snapped onto the side wall of the first shielding plate 12. The base plate 11, the first shielding plate 12 and the second shielding plate 13 are made of boron carbide polyethylene.

[0030] The splicing assembly includes a fixed frame 21, a fixed shaft 22, a first retaining ring 23, and a first connecting plate 24. The fixed frame 21 is attached to the surface of the first shielding plate 12. The fixed shaft 22 passes through the middle of the fixed frame 21. The lower end of the first retaining ring 23 passes through the outer surface of the fixed shaft 22 and is located inside the fixed frame 21. The first connecting plate 24 is fixed to one side of the first retaining ring 23.

[0031] The base plate 11 is used to fix the first shielding plate 12 and the second shielding plate 13. The fixing frame 21 serves as the external frame of the retaining ring assembly, fixed to the surface of the first shielding plate 12, and provides structural support. The fixing shaft 22 serves as the rotation axis of the first retaining ring 23 and the second retaining ring 26. The first retaining ring 23 opens outward under the elastic force of the first spring 25 and cooperates with the second retaining ring 26 to clamp the retaining block 29, thereby positioning the second shielding plate 13. The first connecting plate 24 serves as the supporting component of the first retaining ring 23, transmits the spring force, and fixes the first spring 25.

[0032] The lower surface of the first connecting plate 24 is fixed with a first spring 25, and the lower surface of the first spring 25 is fixed with the inner wall of the fixed frame 21. The middle of the outer surface of the fixed shaft 22 is rotatably penetrated by a second retaining ring 26, and the outer side of the second retaining ring 26 is fixed with a second connecting plate 27.

[0033] The second retaining ring 26 is symmetrically designed with the first retaining ring 23. It opens outward under the elastic force of the second spring 28 to clamp the retaining block 29 together. The second connecting plate 27 supports the second retaining ring 26 and fixes the second spring 28.

[0034] A second spring 28 is fixed to one side of the outer surface of the second connecting plate 27, and one end of the second spring 28 is fixed to the inner wall of the fixing frame 21. A locking block 29 is locked inside the first locking ring 23 and the second locking ring 26, and a connecting block 291 is fixed to one side of the locking block 29. One side of the connecting block 291 is pasted to the outer surface of the second shielding plate 13.

[0035] The second spring 28 provides elastic force, causing the second retaining ring 26 to automatically reset and clamp the retaining block 29 after it enters, thus enhancing the stability of the connection. The retaining block 29 is inserted between the first retaining ring 23 and the second retaining ring 26 as a connection medium. The connecting block 291 is attached to the outer surface of the second shielding plate 13 to transmit the force on the retaining block and ensure its stable position.

[0036] Working principle:

[0037] When the first shielding plate 12 and the second shielding plate 13 are spliced, the locking block 29 is aligned with the first retaining ring 23 and the second retaining ring 26. Under the connection of the first spring 25 and the second spring 28, the fixed shaft 22 is fixedly connected to the first retaining ring 23 and the second retaining ring 26, so that the first retaining ring 23 and the second retaining ring 26 open outward, and the locking block 29 is inserted into the first retaining ring 23 and the second retaining ring 26. At this time, under the elastic force of the first spring 25 and the second spring 28, the first retaining ring 23 and the second retaining ring 26 tightly lock the locking block 29, thus positioning the first shielding plate 12 and the second shielding plate 13.

[0038] This step eliminates the need for bolts on the shielding plate, avoids drilling holes in the boron carbide polyethylene shielding plate, prevents cracks or stress concentration caused by drilling, protects the integrity of the shielding plate, avoids radiation leakage, and improves the quality of shielding plate installation.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The protective assembly includes a slide rail 31, a slider 32, and a movable plate 33. The slide rail 31 is attached to the middle of the outer surface of the second shielding plate 13. The slider 32 is slidably placed inside the slide rail 31. The movable plate 33 is fixed to one side of the slider 32. A protective plate 34 is fixed to the outer surface of the movable plate 33, and the protective plate 34 covers the joint between the first shielding plate 12 and the second shielding plate 13.

[0041] The slide rail 31 provides a track for the movement of the movable plate 33 and the protective plate 34. The slider 32 drives the movable plate 33 and the protective plate 34 to move by sliding, so as to cover or expose the joint. The movable plate 33 serves as a support carrier for the protective plate 34, and transmits the movement of the slider 32 to the protective plate 34. The protective plate 34 covers the joint between the first shielding plate 12 and the second shielding plate 13, blocking radiation leakage.

[0042] Working principle:

[0043] After the first shielding plate 12 and the second shielding plate 13 are spliced ​​together by the splicing assembly, push the slider 32 to move the movable plate 33. The movable plate 33 simultaneously moves the protective plate 34 so that the protective plate 34 covers the joint between the first shielding plate 12 and the second shielding plate 13.

[0044] In this step, the protective plate 34 covers the joint between the first shielding plate 12 and the second shielding plate 13, effectively blocking the penetration of neutrons, gamma rays, etc., and preventing the joint from becoming a weak point for radiation leakage.
