Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to a non-reflective shielding door and a sliding door using the same. Background Technology

[0002] Due to the unique advantages of neutrons, such as being uncharged, having strong penetrating power, possessing a magnetic moment, being sensitive to light elements, and being able to distinguish isotopes and neighboring elements, neutron scattering technology plays an irreplaceable role in scientific research and industrial applications in fields such as physics, chemistry, new energy, life sciences, medicine, materials science, engineering, and national security.

[0003] For example, neutron scattering spectrometers typically use neutron conduits to guide neutrons into the conduit hall, and then multiple spectrometers are set up along each conduit beamline. Because neutrons are uncharged and have strong penetrating power, they pose a very serious threat to the human body. Therefore, neutron applications are usually conducted in non-reflective shielded rooms, which must be able to eliminate or minimize the reflection interference caused by neutrons within the room. Shielded doors are the main passage for personnel and equipment to enter and exit the shielded room, making them an extremely important safety guarantee.

[0004] For example, CN108131083B discloses a suspended sliding neutron shielding door, which uses a combination of a front steel plate, a back steel plate, and a boron-containing polyethylene plate sandwiched in between. The steel plate itself has a neutron-moderating effect, and boron-containing polyethylene is the main neutron-absorbing material with a higher absorption efficiency than steel and concrete. However, during neutron scattering experiments using a neutron scattering spectrometer, a large number of stray neutrons and gamma rays are usually generated. Studies have found that the shielding door composed of steel plates and boron-containing polyethylene plates cannot effectively shield neutrons and gamma radiation simultaneously.

[0005] Therefore, in view of the defects in the use of the shielding door using the above technology, it is necessary to further optimize and improve its structure. Utility Model Content

[0007] The primary objective of this invention is to provide a sliding door that addresses the technical problem of optimizing its shielding effect.

[0031] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] Example 1: Please refer to Figures 1 to 6 As shown, this embodiment provides a non-reflective shielding door, including: an outer frame layer 2 and an inner core layer 3 disposed inside the outer frame layer 2; the entire outer frame layer 2 is roughly a cuboid structure with an internal cavity, and the inner core layer 3 is also formed as a cuboid structure, and it can be perfectly accommodated in the cavity of the outer frame layer 2.

[0033] Specifically, firstly, considering the overall view of the door frame 1 during the use of the non-reflective shielding door, the outer frame layer 2 includes a main double-sided aluminum-plastic composite panel 21 facing inwards, a steel plate 22 facing away from inwards, and a pair of side double-sided aluminum-plastic composite panels 23 for connecting the double-sided aluminum-plastic composite panel and the steel plate 22. That is to say, when the non-reflective shielding door is in use, the main double-sided aluminum-plastic composite panel 21 faces inwards, while the steel plate 22 faces away from inwards.

[0034] It should be noted that, theoretically, considering the cuboid structure of the outer frame layer 2, steel plates 22 could be installed at its top and bottom, but to reduce the overall bulkiness of the shielding door, and since the height of the shielding door in use is usually greater than the height of the door frame 1, the shielding effect is not affected even if steel plates 22 are not installed at the top and bottom of the outer frame layer 2. Furthermore, the top and bottom are usually not exposed to the view, so omitting the steel plates 22 does not affect either aesthetics or shielding effectiveness. Therefore, no absolute limitation is made here regarding whether or not steel plates 22 are installed at the top and bottom of the outer frame layer 2.

[0035] More specifically, referring to the accompanying drawings, in one optional embodiment, a first steel support frame 4 is provided between the inner core layer 3 and the steel plate 22. A second steel support frame is provided between the inner core layer 3 and the main double-sided aluminum composite panel 21. A side plasterboard 25 is also provided between the inner core layer 3 and the side double-sided aluminum composite panel 23. In this optional embodiment, the first steel support frame 4 and the second steel support frame 5 have the same structure, generally comprising multiple straight tubes arranged longitudinally and transversely, and oblique tubes that are inclined to each straight tube. The use of the first steel support frame 4 and the second steel support frame 5 here is mainly to balance reducing the overall bulkiness of the shielding door and ensuring the strength of the overall outer frame layer 2.

[0036] Considering that the non-reflective shielding door of this embodiment needs to be connected to the sliding drive mechanism at the top of the shielding door when applied to a sliding door, in order to ensure a reliable fit between the outer frame layer 2 and the sliding drive mechanism, this embodiment also provides a top connecting pipe 6 on the top of each side double-sided aluminum-plastic composite panel 23 for connecting to the first steel support frame 4 and the second steel support frame 5 respectively. This structure allows the top connecting pipe 6 to be enclosed with the first steel support frame 4 and the second steel support frame 5 to form a reliable cuboid structure.

[0037] In addition, considering the need to reduce the overall bulkiness of the shielding door and ensure the strength of the overall outer frame layer 2, a first L-shaped corner steel frame 7 is provided between the side double-sided aluminum plastic plate 23 and the first steel support frame 4; and a second L-shaped corner steel frame 8 is provided between the side double-sided aluminum plastic plate 23 and the second steel support frame 5.

[0038] Based on the above structure, the inner core layer 3 will be described next. It comprises a boron-containing rubber layer 31, a lead-antimony alloy plate layer 32, and a boron-containing polyethylene plate layer 33, arranged sequentially from the inside to the outside of the door. The boron-containing rubber layer 31 is mainly used for initial neutron absorption, the lead-antimony alloy plate layer 32 is mainly used for absorbing gamma rays, and the boron-containing polyethylene plate layer 33 is a material for further neutron absorption. For the inner core layer 3 of this embodiment, the boron-containing rubber layer 31, the lead-antimony alloy plate layer 32, and the boron-containing polyethylene plate layer 33, after being stacked sequentially, can be fastened together using, for example, but not limited to, screws.

[0039] Furthermore, regarding the thickness of the three components of the inner core layer 3—the boron-containing rubber layer 31, the lead-antimony alloy plate layer 32, and the boron-containing polyethylene plate layer 33—the boron-containing rubber layer 31 has the smallest thickness, while the thicknesses of the lead-antimony alloy plate layer 32 and the boron-containing polyethylene plate layer 33 are both greater than that of the boron-containing rubber layer 31. The thickness of the lead-antimony alloy plate layer 32 can be slightly less than or equal to the thickness of the boron-containing polyethylene plate layer 33. The specific thickness parameters of these three components are designed adaptively based on the varying overall size and weight requirements of the non-reflective shielding door for different application scenarios; therefore, this embodiment does not impose absolute limitations on these parameters.

[0040] In one alternative implementation, the boron-containing rubber layer 31 is made of rubber with a boron content of 3%-5%. The lead-antimony alloy sheet layer 32 is made of a lead-antimony alloy with an antimony content of 3%-5%. The boron-containing polyethylene sheet layer 33 is made of polyethylene with a boron content of 3%-10%. Boron has a higher neutron absorption efficiency than steel and heavy concrete, and the density of the boron-containing polyethylene sheet layer 33 is much lower than that of the steel plate 22 and heavy concrete. Therefore, the weight of the non-reflective shielding door made of this inner core layer 3 is much smaller than that of a traditional heavy concrete shielding door.

[0041] In summary, for the non-reflective shielding door of this embodiment, the inner core layer 3 can not only shield neutrons but also gamma radiation. In combination with the main double-sided aluminum plastic plate 21, steel plate 22 and a pair of side double-sided aluminum plastic plates 23 of the outer frame layer 2, it can reduce the overall weight of the shielding door to meet the movement requirements of the sliding door while ensuring its reliable shielding effect.

[0042] Example 2: Please refer to Figures 1 to 6 As shown, based on the non-reflective shielding door of Embodiment 1, this embodiment provides a sliding door, including: the non-reflective shielding door of Embodiment 1, and a translation drive mechanism connected to the non-reflective shielding door for driving the non-reflective shielding door to perform translational movement.

[0043] It should be noted that the translation drive mechanism here can be any mature means in the prior art. This embodiment does not make an absolute limitation on it, nor does it make any specific structural improvements. It can be, for example, but not limited to the relevant structure disclosed in CN108131083B, which generally includes a hanging base 91 connected to the outer frame layer 2, a moving trolley 92 connected to the hanging base 91, a translation guide rail 93 cooperating with the moving trolley 92, and a driver 94 for driving the moving trolley 92 to move on the translation guide rail 93.
