Description

Technical Field

[0001] The present invention relates to the technical field of radiation protection nails for radiation protection, and particularly relates to a special-shaped material-saving radiation protection nail and a radiation protection method therefor. Background Art

[0002] With the improvement of medical level and the popularization of radiology in China, the radioactive isotopes or radiation devices used in radiation medicine are increasing day by day. At the same time, the use of civilian nuclear technology has also had more applications with the development of science and technology. However, while nuclear technology brings convenience, it also brings the problem of radiation pollution. When using radiation devices, the radiation protection situation of the radiation device machine room often needs to be considered. At present, the radiation protection materials used in China generally include barium sulfate protection boards, barium sulfate cement, red bricks, concrete, lead plates, etc. Among them, red bricks and concrete are not environmentally friendly in the production process and are not easy to construct during the construction process; although barium sulfate cement is easy to construct and has good economy, after the construction of barium sulfate cement, cracks are easily formed, which will damage the protection shield of the radiation device machine room. Especially for the decorated radiation device machine room, the formed cracks are more difficult to detect; lead plate protection is also a commonly used radiation protection method. Lead is a heavy metal, which is toxic itself. At the same time, lead is also an important metal resource. Generally, lead plate protection is not adopted for small Class III radiation device machine rooms, and lead plate protection has good effect and economy for large Class II radiation devices, etc. Barium sulfate boards have the characteristics of simple construction and good economy, and are widely used in the field of radiation device protection, especially widely used in the protection of Class III radiation device machine rooms. Whether it is a lead plate or a barium sulfate board, it needs to be fixed to the wall or the corresponding keel frame during use. At present, for the construction of barium sulfate boards, steel nails and threaded nails are used to fix them to the wall or the keel frame. The steel nails and threaded nails cause perforations in the protection materials, and lead plates are used for protection compensation, which will cause excessive use of lead plates. For the construction of lead plates, structural adhesives or universal adhesives are generally used to stick them to the wall, but the service life of the adhesives is not long, which will cause the lead plates to fall off. When using steel nails for fixation, the original radiation shield is damaged, and radiation shield compensation is also required, thus causing waste of protection materials.

[0003] Among the current radiation protection materials, lead plates and barium sulfate boards are widely used, but the radiation protection perforations caused by the construction of lead plates and barium sulfate boards will affect the radiation shielding effect. Therefore, there is an urgent need for a protection and fixation component that can effectively prevent radiation leakage and also play a fixation effect. Summary of the Invention

[0004] Aiming at the problem that ordinary steel nails fix radiation protection materials to form punctures, which affects the radiation shielding effect, the present invention provides a special-shaped material-saving radiation protection nail and a radiation protection method therefor.

[0005] The solution adopted by the present invention to solve its technical problems is as follows: A special-shaped radiation-proof nail for saving materials, comprising a nail body and a protective nail cap. One end of the nail body is set as a tip, and the other end is fixedly connected with the protective nail cap. The protective nail cap is a multi-layer structure, including an outer layer, a radiation-proof layer and an inner layer. The inner layer is fixedly connected with the nail body, the radiation-proof layer is located between the inner layer and the outer layer, and the outer layer, the radiation-proof layer and the inner layer are fixedly connected to each other.

[0006] Preferably, the protective nail cap is an arc-shaped structure, and the arc-shaped structure is a circular arc centered on the nail body.

[0007] Preferably, the radiation-proof layer is made of lead plate, and the outer layer is made of stainless steel. The outer layer, the radiation-proof layer and the inner layer are fixedly connected by welding.

[0008] Preferably, the outer edge of the protective nail cap is set as a conical inclined plane.

[0009] A radiation-proof method for a special-shaped radiation-proof nail for saving materials includes the following steps: S1. Wall leveling Level the surface of the wall or the keel frame; S2. Paving and fixing Pave the radiation protection board on the wall or the keel frame; S3. Drilling and driving in the special-shaped radiation-proof nail for saving materials Drill holes in the radiation protection board. The drilling depth is the same as the thickness of the protective nail cap, and the drilling depth is less than the thickness of the lead plate or barium sulfate board. Drive the special-shaped radiation-proof nail for saving materials into the drilled holes; S4. Hammering the nail Hammer the outer layer of the protective nail cap to drive the protective nail cap into the drilled hole, and continue to hammer the protective nail cap to make the protective nail cap flat and completely fit into the drilled hole of the radiation protection board.

[0010] Preferably, in step S3, pre-drill holes in the radiation protection board.

[0011] Preferably, the drill hole in step S3 is a conical hole, and the diameter of the conical hole gradually increases from outside to inside.

[0012] Preferably, a central notch (5) is provided at the center of the drill hole in step S3 to facilitate positioning the center of the drill hole for the special-shaped radiation-proof nail for saving materials.

[0013] The beneficial effects of the present invention: The special-shaped radiation-proof nail for saving materials provided by the present invention can not only effectively reduce radiation leakage, but also provide excellent reinforcement and fixing functions. At the same time, it can also save the use of radiation-proof materials. By embedding into the wall or the protective board, it can effectively prevent radiation leakage, and at the same time reduce the use of protective materials, increase the protection effect, simplify the protection construction and enhance the fixing strength of the protection board.

[0014] For the aspect of saving protective materials, when using ordinary steel nails or threaded nails for fixation, each nail hole requires a lead plate of about 2 cm × 2 cm. When using the radiation-proof nail of the present invention, each nail hole requires a lead plate with a radius of about 0.8 cm, saving about 50.24% of the lead plate. Moreover, the radiation-proof nail provided by the present invention has good practicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below.

[0018] Embodiment 1: In order to achieve the effect of radiation protection shielding in the ray device machine room, it is necessary to lay and fix the radiation protection plate 2 on the wall surface. The radiation protection plate 2 is generally a lead plate or a barium sulfate plate. The current conventional fixing method is to directly fix the radiation protection plate 2 on the wall or the keel frame 1 using steel nails 3 or threaded nails. The steel nails 3 and threaded nails will cause perforations in the protective material, and radiation leakage will occur at the perforated parts, as Figure 1 shown. Therefore, a lead plate is additionally provided outside the steel nails and threaded nails for protection compensation. On the one hand, the protection compensation causes excessive use of the lead plate. On the other hand, the lead plate used for compensation also needs to be fixed. Glue fixation is prone to falling off, and fixing with steel nails 3 will cause damage to the shielding, requiring multiple compensations and resulting in waste.

[0019] Therefore, the present invention provides a special-shaped material-saving radiation-proof nail that can effectively reduce radiation leakage and provide excellent reinforcement and fixation functions. Its specific structure is asFigure 2 As shown in the figure, the radiation protection nail 4 includes a nail body 41. One end of the nail body 41 is provided with a tip for penetration, and the other end is fixed with a protective cap for protecting and compensating the nail hole.

[0020] The protective nail cap 42 includes a three-layer structure, which are an inner layer 421, a radiation protection layer 422, and an outer layer 423 respectively. The inner layer 421 is directly fixed to the nail body 41. The radiation protection layer 422 is fixed on the inner layer 421, and the outer layer 423 is fixed outside the radiation protection layer 422. The inner layer 421 is directly fixed to the nail body 41 to provide high tensile strength, so that the radiation protection plate 2 is firmly fixed to the wall. The radiation protection layer 422 is made of a lead plate for protection and compensation. The outer layer 423 is used for contacting and knocking, and at the same time provides a relatively beautiful surface.

[0021] Therefore, the inner layer 421 and the nail body 41 are integrated. The inner layer 421 is made of carbon steel, which has good ductility and tensile strength. The radiation protection layer 422 made of a lead plate is fixed on the inner layer 421 by resistance welding. The outer layer 423 can be made of carbon steel or stainless steel. Carbon steel has the advantages of low cost and easy plastic processing. Stainless steel can provide better sealing protection to avoid corrosion and damage of the lead plate of the radiation protection layer 422. The outer layer 423 is fixed on the lead plate radiation protection layer 422 by resistance welding.

[0022] The protective nail cap 42 is in an umbrella-shaped arc with the nail body 41 as the center.

[0023] As Figure 3 shown, the radiation protection usage method of the special-shaped material-saving radiation protection nail is as follows: First, level the surface of the wall or the keel frame 1, and lay the radiation protection plate 2 on the wall or the keel frame 1. Use a hole opener to drill a hole on the corresponding position on the surface of the radiation protection plate 2 with the same diameter and thickness as the protective nail cap 42. The hole does not penetrate the laid radiation protection plate 2, that is, the drilling depth is the same as the thickness of the protective nail cap, and the drilling depth is less than the thickness of the lead plate or barium sulfate plate. Here, the diameter of the protective nail cap 42 is the diameter of the arc-shaped edge.

[0024] The reason for setting the drilling depth to be the same as the thickness of the protective nail cap and less than the thickness of the lead plate or barium sulfate plate is as follows: 1. If the drilling depth is greater than or equal to the thickness of the lead plate or barium sulfate plate, the shielding effect of the original protection will be damaged; 2. The nail body part is not inserted by drilling. The nail body part is embedded by knocking. If it is inserted by drilling, the nail will not be firmly fixed.

[0025] In summary, the present invention ensures the beauty of the wall surface (does not affect the subsequent decoration of the wall surface) by setting the drilling with a specific thickness, and can also provide reliable radiation protection.

[0026] During the process of drilling with the hole opener, a drill bit at the center of the hole opener is used to set a drilling center notch 5 at the center of the drill hole, which facilitates the positioning when the radiation protection nail 4 is nailed in. The drilling center notch 5 is used to fit the root of the tip of the radiation protection nail, providing central positioning when knocking in the nail.

[0027] Align the tip of the radiation protection nail 4 with the drilling center notch 5, and nail the radiation protection nail 4 into the radiation protection plate 2, so that the protective nail cap 42 of the radiation protection nail 4 is embedded into the drill hole opened in the radiation protection plate 2. At the same time, the nail body 41 penetrates the radiation protection plate 2, and the tip is embedded into the wall or the keel frame 1.

[0028] The outer layer 423 and the inner layer 421 in the protective nail cap 42 tightly hold the radiation protection plate 2, so that the radiation protection plate 2 and the wall or the keel frame 1 are tightly held together. The protective nail cap 42 is knocked until it is flush with the surface of the radiation protection plate 2. Since the protective nail cap 42 is arc-shaped, the diameter of the flattened top cap increases, so that the edge of the top cap forms an extrusion with the drill hole wall of the radiation protection plate 2, so that the lead plate of the radiation protection layer 422 can be hermetically docked with the radiation protection plate 2, further preventing radiation leakage, and completing the construction of the ray device machine room.

[0029] Example 2: In Example 1, the edge of the arc-shaped protective nail cap 42 and the inner wall of the drill hole are both flat. During the process of knocking the protective nail cap 42 flat, the top cap squeezing the inner wall of the drill hole will form uneven extrusion marks, which are not only unbeautiful, but also the contact surface between the protective nail cap 42 and the edge of the drill hole is a straight surface, which is not conducive to radiation protection.

[0030] As Figure 4 shown, in this embodiment, the edge of the protective nail cap 42 is set as a conical inclined surface, and the conical inclined surface shrinks and inclines from the inner layer 421 to the outer layer 423, that is, the diameter decreases from the inner layer 421 to the outer layer 423 in turn.

[0031] As Figure 5 shown, its usage method is: a conical drill hole is set on the radiation protection plate 2, and the diameter of the conical drill hole gradually increases from the outside to the inside. The conical drill hole matches the protective nail cap 42 with a conical inclined surface.

[0032] The diameter of the inner edge of the protective nail cap 42 is the same as the diameter of the conical hole opening, so that the protective nail cap 42 can be easily nailed into the conical hole. Knock the top cap to make it flat. The diameter of the flattened top cap increases to fill the conical hole, and the conical inclined surface of the top cap matches the inner wall of the conical hole to achieve sealing.

[0033] The structure of the protective nail cap 42 provided in this embodiment can avoid the generation of marks between the top cap and the drill hole after the top cap is knocked flat. At the same time, the docking surface between the top cap and the drill hole forms a Z-shaped bend, which can provide better protection effect.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.
