Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a medical radiation protection structure for a duct cable tray encased in a lead plate through a wall. Background Technology

[0002] Medical radiation protection structures are architectural or engineering protection systems specifically designed to shield or reduce the harm of ionizing radiation to personnel, equipment and surrounding areas in medical environments.

[0003] A search revealed Chinese patent CN215406704U, which discloses a medical radiation-proof wall structure, relating to building structure technology. The structure includes a building base with multiple radiation-proof walls within it. These walls are joined together to form the main body of the building, which contains a radiation-proof chamber. Entrances and exits are provided on the radiation-proof walls. This technical solution involves creating a radiation-proof chamber on the floor of a medical room, which is then constructed by joining multiple radiation-proof walls. This chamber can be freely combined to meet the hospital's specific needs, providing radiation protection for instruments and equipment located within it. Gaps created when multiple walls are joined are blocked by other walls, ensuring that the joints between the walls are not on the same horizontal plane. This prevents radiation generated by instruments within the radiation-proof space from scattering out through the gaps, thus protecting personnel outside the space.

[0004] Based on the above search and existing technology, the following findings were made:

[0005] Existing patents use staggered splicing walls to cover gaps, but the materials at the splicing points themselves have radiation leakage, and since no flexible sealing materials are used, they cannot block radiation scattering; moreover, the radiation-proof walls are fixed splicing structures, which cannot adapt to the vibration and displacement of air ducts and cable trays, and gaps may appear due to deformation after long-term use, so they have certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a medical radiation protection structure for duct cable trays encased in lead plates through walls. The radiation protection structure is simple to construct and has both high protection and economy.

[0007] The technical solution to achieve the purpose of this utility model is: a medical radiation protection structure for a duct cable tray encased in a lead plate through a wall, comprising a concrete wall and a duct cable tray, wherein the duct cable tray is installed inside the concrete wall, and further comprising a protective plate assembly.

[0008] The protective panel assembly includes an upper irregular lead protective panel that is fitted over the outside of the air duct cable tray.

[0009] Preferably, a flexible lead rubber pad is fixedly installed on the outside of the air duct cable tray, and a fireproof nano aerogel is fixedly installed between the flexible lead rubber pad and the concrete wall. Both the flexible lead rubber pad and the fireproof nano aerogel are located inside the concrete wall.

[0010] Preferably, an internal medical lead plate is fixedly installed between the outer side of the concrete wall and the upper irregular lead protective plate, and the upper irregular lead protective plate has a slot.

[0011] Preferably, a lower irregular-shaped lead protective plate is provided at the bottom of the upper irregular-shaped lead protective plate, and a buckle is fixedly installed on the lower irregular-shaped lead protective plate, the buckle being engaged with a slot.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model adopts a double-layer wrapping structure of medical lead plate and irregularly shaped lead protective plate, which reduces the risk of radiation leakage through physical superposition, and the protective effect is significantly better than that of a single-layer lead plate; the contact length between the irregularly shaped lead protective plate and the duct cable tray is ≥2 times the length of the long side of the duct, ensuring seamless coverage; the irregularly shaped lead protective plate supports on-site size customization to adapt to different specifications of duct cable trays, and achieves rapid assembly through snap-fit ​​connection, reducing welding or bolt fixing steps.

[0014] Secondly, this utility model uses fire-resistant nano-aerogel to replace rock wool, which has both fireproof and radiation shielding functions, simplifying the construction process; flexible lead rubber pads fill the joints, which absorb vibration and enhance sealing, avoiding radiation leakage due to structural deformation.

[0015] This invention addresses the problems of existing patents that use staggered splicing walls to cover gaps, but the materials at the splicing points themselves can leak radiation, and the lack of flexible sealing materials makes it impossible to block radiation scattering; moreover, the radiation-proof walls are fixed splicing structures that cannot adapt to the vibration and displacement of air ducts and cable trays, and gaps may appear due to deformation after long-term use.

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved medical radiation protection structure for through-wall lead plate enclosure of air duct cable trays. The technical solution of this utility model is as follows:

[0026] Example 1

[0027] like Figures 1-2 As shown, a medical radiation shielding structure with lead plate encapsulation for through-wall ductwork cable trays includes a concrete wall 1 and a ductwork cable tray 2. The ductwork cable tray 2 is installed through the interior of the concrete wall 1, without affecting the sealing construction of the electromechanical ductwork cable tray 2. On-site installation is convenient and quick. It also includes a protective plate assembly.

[0028] The protective panel assembly includes an upper irregular lead protective panel 4 that is fitted onto the outside of the air duct cable tray 2. By adopting an irregular lead protective panel and a redundant radiation-proof lead plate wrapping structure of medical lead plate, the possibility of radiation leakage is reduced.

[0029] Example 2:

[0030] Based on the first embodiment of this application which provides a medical radiation protection structure for duct cable trays encased in lead plates through walls, the second embodiment of this application proposes another medical radiation protection structure for duct cable trays encased in lead plates through walls. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 3-5As shown, a flexible lead rubber pad 6 is fixedly installed on the outside of the duct cable tray 2. A fireproof nano aerogel 7 is fixedly installed between the flexible lead rubber pad 6 and the concrete wall 1. Both the flexible lead rubber pad 6 and the fireproof nano aerogel 7 are set inside the concrete wall 1. The fireproof nano aerogel 7 replaces rock wool and has functions such as fireproof, high temperature resistance and radiation shielding. The flexible lead rubber pad 6 adapts to the vibration of the duct cable tray 2 and avoids joint leakage.

[0033] As a further embodiment of this utility model, an internal medical lead plate 3 is fixedly installed between the outer side of the concrete wall 1 and the upper irregular lead protective plate 4. The upper irregular lead protective plate 4 has a slot. The lead plate is customized and designed according to different sizes on site, which can be adapted to the radiation protection construction of ducts and cable trays of various sizes through the wall, and has strong applicability.

[0034] Furthermore, a lower irregular-shaped lead protective plate 5 is provided at the bottom of the upper irregular-shaped lead protective plate 4. A buckle 501 is fixedly installed on the lower irregular-shaped lead protective plate 5. The buckle 501 is snapped into the slot. The connection through the buckle 501 supports quick assembly and size adjustment, thereby improving construction efficiency.

[0035] The specific working method is as follows: First, during the construction of the concrete wall 1, an installation opening for the air duct cable tray 2 is reserved. After the concrete wall 1 reaches its curing age, the internal medical lead plate 3 is installed. Second, after the internal medical lead plate 3 is installed, fireproof sealing is carried out between the air duct cable tray 2 and the concrete wall 1 using flexible lead rubber pads 6 and fireproof nano aerogel 7. In addition, irregularly shaped lead protective plates can be installed simultaneously. These plates must fully wrap around the air duct cable tray 2, and the interplay between the clips 501 and the slots ensures a tighter connection between the irregularly shaped lead protective plates, thus completing the implementation of this structure. Finally, to ensure safety, the length of the contact portion between the special irregularly shaped lead protective plate and the air duct cable tray 2 must be greater than twice the length of the long side of the air duct cable tray 2, and the length of the contact portion with the internal medical lead plate 3 should not be less than 50cm.

[0036] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
