Description

Technical Field

[0001] This utility model relates to the field of radiation shielding equipment technology, specifically a shielding cover adapted for use with lead-boron polyethylene shielding plates. Background Technology

[0002] Radiation protection is crucial in numerous fields, including the nuclear industry, medical radiological equipment, and scientific research laboratories. Lead-boron polyethylene (BOPE) shielding panels are widely used for radiation shielding due to their excellent comprehensive shielding performance, providing good shielding against fast neutrons, thermal neutrons, and gamma radiation, as well as their lightweight and dimensional stability.

[0003] Currently, most existing shielding covers compatible with lead-boron polyethylene shielding panels adopt a cuboid frame structure, consisting of four side frames. Typically, one of the side frames is designed to be openable to facilitate operation of internal equipment. However, the existing opening and closing range is greatly limited. In most cases, the openable side frame can only rotate at a small angle and cannot be fully opened. This causes great inconvenience for the entry and exit of larger equipment. When installing large radiation source equipment or replacing or repairing large internal components, operators need to work in a narrow opening and closing space. This not only makes the operation difficult and inefficient, but also increases the risk of collision with the shielding panel or equipment due to the limited operating space, thereby affecting the shielding effect or damaging the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a shielding cover adapted for use with lead-boron polyethylene shielding plates, thereby solving the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a shielding cover adapted for use with lead-boron polyethylene shielding plates, comprising:

[0006] The shielding cover itself;

[0007] The extension component includes a support column, a vertical rod, and a hole. The support column is fixed to the top of the shielding plate, the shielding cover body is located on the top of the shielding plate, the hole is opened on the top of the shielding cover body, the vertical rod is movably connected to the inside of the support column, and the upper part of its outer surface is fixedly connected to the inside of the hole.

[0008] Furthermore, a limiting plate is fixedly connected to the top of the upright, the limiting plate is suspended from the top of the shielding cover body, and an observation window is provided on the outer surface of the shielding cover body.

[0009] Furthermore, guide grooves are provided on both sides of the outer surface of the support column, and guide blocks are provided at the lower part of both sides of the outer surface of the upright, with the guide blocks movably connected inside the guide grooves.

[0010] Furthermore, a rubber block is adhered to the top of the guide block, and the rubber block is snapped into the top of the support column.

[0011] Furthermore, the top of the shielding plate is provided with an inner groove, and a sealing gasket is adhered to the bottom of the shielding cover body, the sealing gasket being embedded inside the inner groove.

[0012] Furthermore, it also includes a fixing component, which includes a corner plate, a socket, and a rod. The corner plate is fixed to the lower part of the corner of the shield body, the socket is opened inside the corner plate, and the rod is fixed to the top of the shield and inserted into the socket.

[0013] Furthermore, a fastening ring is threaded onto the outer surface of the insertion rod, and the fastening ring is pressed against the top of the corner plate.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through the design of the extension component, allows the upright to extend inside the support column. Combined with the sliding cooperation of the guide block and the guide groove, the operator only needs to apply force by hand to lift the shielding cover body upward and move it to the upper part, so that the shielding plate can be fully exposed. This completely solves the problem of difficulty in entering and exiting large components caused by the limited opening and closing range of traditional openable side frames. Whether it is placing or replacing larger-sized equipment or repairing large internal components, it can provide sufficient operating space, significantly reduce the difficulty of operation, improve work efficiency, and reduce the risk of equipment collision caused by limited operating space.

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.

[0026] 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.

[0027] Please see Figure 1-4 As shown, this utility model is a shielding cover adapted for use with lead-boron polyethylene shielding plates, comprising:

[0028] Shielding cover body 11;

[0029] The extension component includes a support column 23, a vertical rod 25, and a hole 291. The support column 23 is fixed to the top of the shielding plate, the shielding cover body 11 is located at the top of the shielding plate, the hole 291 is opened at the top of the shielding cover body 11, the vertical rod 25 is movably connected to the inside of the support column 23, and the upper part of its outer surface is fixedly connected to the inside of the hole 291.

[0030] The operator applies an upward force to the shielding cover body 11. This force is transmitted to the upright 25, causing the upright 25 to extend upward along the inside of the support column 23. The area of ​​the shielding plate that was originally covered by it is fully exposed, forming a sufficiently spacious operating space to facilitate the smooth entry and exit of larger equipment and the operation of operators to place, replace or repair large components.

[0031] A limiting plate 22 is fixedly connected to the top of the upright 25. The limiting plate 22 is suspended on the top of the shielding cover body 11. An observation window 21 is provided on the outer surface of the shielding cover body 11.

[0032] Through the observation window 21, operators can observe the operation of the internal equipment in real time without opening the shielding cover, which not only ensures the safety of the operators, but also facilitates the timely detection and handling of equipment problems.

[0033] The outer surface of the support column 23 is provided with guide grooves 27 on both sides, and the lower part of the outer surface of the upright 25 is provided with guide blocks 26, which are movably connected to the inside of the guide grooves 27.

[0034] When the shield body 11 moves upward, the guide blocks 26 on both sides slide synchronously in the guide grooves 27 corresponding to the support column 23. The guide grooves 27 limit and guide the guide blocks 26, ensuring that the shield body 11 maintains a stable posture during the upward process, avoiding deviation or shaking, and ensuring the smoothness of the lifting process.

[0035] A rubber block 24 is adhered to the top of the guide block 26, and the rubber block 24 is snapped onto the top of the support column 23;

[0036] Because the rubber block 24 has a certain degree of elasticity, under the weight of the shield body 11 itself and the pressure applied by the operator, the rubber block 24 undergoes elastic deformation and is tightly locked onto the top of the support column 23, thereby firmly fixing the shield body 11 in the upper position and preventing it from falling accidentally during operation.

[0037] The top of the shielding plate has an inner groove 29, and the bottom of the shielding cover body 11 is bonded with a sealing gasket 28, which is embedded in the inner groove 29.

[0038] The sealing gasket 28 is embedded inside the inner groove 29 to provide a seal and ensure the overall shielding performance of the shielding cover.

[0039] Working principle:

[0040] First, the upright 25 is nested inside the support column 23, forming a retractable support structure. When large components need to be operated, the operator applies an upward force to the shielding cover body 11. This force is transmitted to the upright 25, causing it to extend upward along the inside of the support column 23. During this process, the guide block 26 slides synchronously in the guide groove 27 corresponding to the support column 23. As the shielding cover body 11 continues to move upward, when it reaches the preset upper position, the rubber block 24 undergoes elastic deformation and engages with the top of the support column 23, thus fully exposing the area of ​​the shielding plate that was originally covered, forming a sufficiently spacious operating space.

[0041] This step facilitates the smooth entry and exit of larger equipment and allows operators to place, replace, or repair large components.

[0042] Please see Figure 1 , Figure 3 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The fixing component includes a corner plate 31, a socket 32, and a plug rod 33. The corner plate 31 is fixed to the lower part of the corner of the shielding cover body 11, the socket 32 ​​is opened inside the corner plate 31, and the plug rod 33 is fixed to the top of the shielding plate and inserted into the socket 32.

[0044] After the shielding cover body 11 is attached to the top of the shielding plate, the insertion rod 33 on the corner plate 31 will be inserted into the preset insertion hole 32 of the shielding plate simultaneously. The cooperation between the insertion rod 33 and the insertion hole 32 not only serves a positioning function.

[0045] The outer surface of the insertion rod 33 is threaded with a fastening ring 34, which is pressed against the top of the corner plate 31;

[0046] Rotating the fastening ring 34 utilizes the threaded structure on the outside of the fastening ring 34 and the insertion rod 33 to move the fastening ring 34 axially along the insertion rod 33 and press it tightly against the surface of the shielding plate. This makes the insertion rod 33 fit more tightly with the insertion hole 32, the shielding cover body 11, and the corner plate 31 with the shielding plate, eliminating gaps to the maximum extent, thereby effectively blocking electromagnetic interference and ensuring that the shielding cover as a whole has reliable shielding performance.

[0047] Working principle:

[0048] After the shielding cover body 11 is attached to the top of the shielding plate, the corner plate 31 is attached to the top of the shielding plate, and the insertion rod 33 on the corner plate 31 is simultaneously inserted into the preset insertion hole 32 of the shielding plate. Finally, the fastening ring 34 is rotated, and the threaded structure of the fastening ring 34 and the insertion rod 33 is used to make the fastening ring 34 move along the axial direction of the insertion rod 33 and press tightly against the surface of the shielding plate.

[0049] This step effectively blocks electromagnetic interference, ensuring that the shielding cover as a whole has reliable shielding performance.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
