Description

Technical Field

[0001] The utility model relates to the technical field of protective plates, in particular to a spliced ​​radiation protective plate. Background Art

[0002] Radiation protection panels have the function of blocking or reducing the spread of radiation (such as X-rays, gamma rays, etc.). Since radiation is harmful to the human body, many special places, such as the radiology department of a hospital, use radiation protection panels on the walls of the building. There are also many places where temporary radiation protection areas are set up and radiation protection panels are also used.

[0003] Existing radiation protection panels are mostly made of heavy metal materials such as lead and lead glass. Although these materials have high radiation absorption capacity, they are also accompanied by problems such as high price and heavy weight. At the same time, lead-containing materials have the risk of environmental pollution and may also pose a threat to human health. In addition, this type of radiation protection panel has a large area and cannot be flexibly spliced. To this end, we propose a spliced ​​radiation protection panel to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a spliced ​​radiation protection plate having good radiation protection performance, light weight, and easy splicing and installation, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spliced ​​radiation protection plate, comprising a radiation protection plate body and a connecting piece, wherein four connecting pieces are embedded in the outer surface of the radiation protection plate body, the radiation protection plate body comprises a supporting layer, a radiation absorbing layer and a wear-resistant layer, the upper surface of the supporting layer is adhered to the radiation absorbing layer, and the upper surface of the radiation absorbing layer is adhered to the wear-resistant layer;

[0008] The connecting part includes a semicircular base, a semicircular plate, a semi-arc strip, an arc groove and a limit screw. The interior of the semicircular base is slidably connected to the semicircular plate, the top surface of the semicircular plate is fixedly connected to the semi-arc strip, the upper surface of the semicircular base is provided with an arc groove, and the upper surface of the semi-arc strip is threadedly connected to the limit screw.

[0009] Preferably, the support layer is made of tungsten-nickel-iron alloy material, and the thickness of the support layer is 2-3 mm.

[0010] Through the above technical solution, although the thickness of the support layer is relatively thin, the density of tungsten-nickel-iron alloy is much higher than that of conventional materials, generally between 17.0 and 18.5 g / cm 3It has excellent absorption capacity for gamma rays or X-rays, so the support layer composed of tungsten-nickel-iron alloy not only has a certain hardness, but also has a certain radiation protection performance. Compared with traditional lead-containing materials, tungsten-nickel-iron alloy is non-toxic and environmentally friendly.

[0011] Preferably, the radiation absorbing layer is made of carbon fiber reinforced plastic, and the thickness of the radiation absorbing layer is 8-10 mm.

[0012] Through the above technical scheme, the radiation absorbing layer adopts carbon fiber reinforced plastic as the main body, and a large number of lead-free radiation absorbing particles are filled inside. Since the carbon fiber material has the advantages of being dense and lightweight, the weight of the entire plate can be greatly reduced, and the lead-free radiation absorbing particles are selected from barium sulfate, tungstate, stannate or a combination thereof, and the average particle size of these particles is in the range of 1 to 10 microns. Since materials such as barium sulfate, tungstate and stannate have high atomic numbers, they can effectively absorb and scatter X-rays and gamma rays. Under the action of electromagnetic waves, high atomic number materials can produce more electron-vacancy pairs, thereby increasing the attenuation of rays. Traditional radiation protection materials mostly use lead-containing compounds, and lead has potential hazards to the environment and human health. The application of lead-free radiation absorbing particles effectively avoids the toxicity problem of lead and meets modern environmental protection requirements. The average particle size of the particles is controlled in the range of 1 to 10 microns, which helps to improve the uniformity and density of the filler, thereby enhancing the shielding effect of the material.

[0013] Preferably, the wear-resistant layer is made of polyethylene, the thickness of the wear-resistant layer is 3-4 mm, and a ceramic coating is sprayed on the surface of the wear-resistant layer.

[0014] Through the above technical solution, the polyethylene material has the properties of corrosion resistance and wear resistance, and a layer of ceramic coating is coated on its outer surface, which can protect the outer surface of the radiation absorption layer and play a protective role.

[0015] Preferably, at least four semicircular grooves are formed through the upper surface of the radiation protection plate body, and a semicircular base is embedded in the semicircular groove, and the semicircular base is connected to the radiation protection plate body by screws.

[0016] Through the above technical solution, a semicircular groove is opened on the upper surface of the radiation protection plate body near the four side edges, and then the connecting piece is embedded in the semicircular groove, and the semicircular base is connected to the radiation protection plate body with screws, and then the semicircular plate and the semi-arc strip are assembled into the semicircular base, and then the limit screw is screwed into the screw hole of the semi-arc strip, so as to realize the assembly of the connecting piece.

[0017] Preferably, a slide groove is provided inside the semicircular base, and a semi-arc strip is slidably connected in the slide groove.

[0018] Through the above technical solution, when the two radiation protection plate bodies are spliced ​​together, the limit screw is turned to make it move in the arc groove of the semicircular base, so that the limit screw drives the semi-arc bar to move, and the semi-arc bar drives the semicircular plate to rotate, so that the semi-arc bar will be inserted into the sliding groove of the other semicircular base, realizing the connection of the two connecting parts, and then realizing the splicing of the two radiation protection plate bodies.

[0020] 1. The utility model provides a radiation protection plate body with a supporting layer, a radiation absorbing layer and a wear-resistant layer. The supporting layer as a base layer has good hardness and radiation resistance. The radiation absorbing layer adopts carbon fiber reinforced plastic as the main body, and is filled with a large number of lead-free radiation absorbing particles. The application of lead-free radiation absorbing particles effectively avoids the toxicity problem of lead and meets modern environmental protection requirements. The average particle size of the particles is controlled within the range of 1 to 10 microns, which helps to improve the uniformity and density of the filler, thereby enhancing the shielding effect of the material. The overall structure has the advantages of lightweight and good radiation resistance.

[0021] 2. The utility model provides a connecting piece. When two radiation protection plate bodies are spliced ​​together, the limiting screw is turned to make it move in the arc groove of the semicircular base. In this way, the limiting screw drives the semi-arc bar to move, and the semi-arc bar drives the semicircular plate to rotate. In this way, the semi-arc bar will be inserted into the sliding groove of the other semicircular base, thereby realizing the connection of the two connecting pieces, and then realizing the splicing of the two radiation protection plate bodies.
