Description

Technology Field

[0001] The present invention relates to the field of construction technology, and more specifically to a space radiation shielding structure. Background Technology

[0002] The paradigm of the space industry is shifting from security and military competition to civilian industry and international cooperation.

[0003] National space agencies, such as NASA and ESA, are cooperating on lunar ground exploration and base establishment, and are competitively pursuing plans to build lunar bases under the leading role of governments.

[0004] The United States and Europe are leaders in the field of space exploration, and the United States is pursuing the Artemis program with the goal of landing the first female astronaut on the moon by 2024 and building a sustainable manned base on the moon by 2028.

[0005] The European Space Agency (ESA) is pursuing the Moon Village project with the goal of building a manned lunar base by 2030 using lunar regolith.

[0006] The construction of a lunar base is intended for purposes such as manned lunar exploration and the extraction of energy resources.

[0007] For lunar exploration and the development of manned bases, it is necessary to be able to cope with the extreme environment of the lunar surface (meteorite impacts, radiation, extreme temperatures, etc.).

[0008] According to research, radiation shielding has been identified as the top priority challenge to overcome in the Moon's extreme environment.

[0009] Generally, the representative radiation shielding facility on Earth, as opposed to in space, is a nuclear power plant.

[0010] Nuclear power plants focus on shielding gamma rays among various radiation elements, such as protons, neutrons, alpha, beta, and gamma rays.

[0011] Since gamma rays have the strongest penetrating power among radiations, exposure to them has very serious effects on human health, such as DNA breakage.

[0012] Considering these characteristics, nuclear power plants use high-density lead walls and concrete walls as radiation shielding facilities.

[0013] It is known that a 1 cm thick lead wall reduces gamma ray penetration intensity by half, and a 6 cm thick concrete wall exhibits the same half-value layer (HVL) performance as a 1 cm thick lead wall.

[0014] Theoretically, a wall of pure lead 10 cm thick can reduce gamma rays to less than 0.1% of the original gamma ray intensity.

[0015] In the space industry, the high density of lead walls is cited as the biggest problem, rather than their high cost or processing difficulties.

[0016] Materials that are difficult to procure locally on the Moon must be sent to the Moon via spacecraft, but transporting high-density, heavy-weight materials like lead is too costly and inefficient.

[0017] For this reason, research is being conducted to use aluminum, which has a density of about 25% of lead, as a radiation shielding material.

[0018] However, considering that cosmic radiation and solar wind radiation consist of high-energy protons and electrons, and that lifting and construction equipment for space and lunar bases has not yet been developed, there is a problem in that aluminum cannot be considered an effective construction material either.

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0041] As illustrated in FIG. 1 and below, the present invention relates to a structure for shielding cosmic radiation, and is composed of a support member (100), a shielding membrane material (200), a filler, a spacing member (300), an end joint part (400), a reinforcing membrane material (500), etc.

[0042] The support member (100) is made of aluminum, reinforced plastic material, etc., and has a structure (plate structure, I-shaped cross-section structure, T-shaped cross-section structure, etc.) equipped with a plate portion (110), and multiple members are installed at intervals to form the frame of the entire structure.

[0043] A through hole (120) (slit) with an elongated structure is formed in the plate portion (110) of the support member (100), and a shielding material (200) is joined by passing through the through hole (120).

[0044] The shielding material (200) is installed between a plurality of support members (100), has a filling portion (201) formed inside, has an injection port for injecting the filling material formed on one side, and is formed as a sealed structure by a flexible material (synthetic resin such as PVC, PVF, PVDF, PTFE, Kevlar, etc.).

[0045] A gaseous or liquid filler is filled into the filling portion (201) of the shielding material (200) so as to shield cosmic radiation.

[0046] For example, hydrogen (H2) and water (H2O), which are effective in shielding protons and neutrons of cosmic radiation, can be used as fillers.

[0047] The spacing member (300) is installed to maintain the spacing between a plurality of support members (100) and may take the form of a cable structure or a rod structure.

[0048] This has the following effects.

[0049] First, since the overall weight is low, the cost of transporting it via spacecraft is low.

[0050] Since the majority of the volume is occupied by a foldable, low-weight membrane material and heavy support members, spacing members, etc., occupy a small proportion, the burden of transport by the spacecraft is low.

[0051] Second, it is possible to effectively shield cosmic radiation containing a large amount of high-energy protons.

[0052] Since a shielding material filled with hydrogen (H2), water (H2O), etc., is used, it is effective for shielding cosmic radiation with special characteristics, such as a high number of high-energy protons.

[0053] Third, lifting and construction are possible even without separate equipment.

[0054] The overall structure is lightweight, and since buoyancy is generated when filled with hydrogen (H2), lifting and construction by human power are sufficiently possible.

[0056] The shielding material (200) is composed of a first film (210), a second film (220), an edge heat-sealed portion (230), and a central heat-sealed portion (240). (Figs. 2 to 7)

[0057] The first membrane (210) and the second membrane (220) are formed into a plate structure by a flexible material, and an injection port is formed on one side of the first membrane (210) or the second membrane (220).

[0058] An edge heat-fused portion (230) is formed by heat fusion to close the longitudinal edge portions of the first membrane (210) and the second membrane (220).

[0059] A plurality of central heat-fused portions (240) are formed at intervals along the width direction of the first film (210) and the second film (220) so that a portion of the inner surface of the first film (210) and a portion of the inner surface of the second film (220) are joined together.

[0060] A filling portion (201) is formed in the inner region of the first membrane (210), the second membrane (220), the edge heat-sealed portion (230), and the plurality of central heat-sealed portions (240).

[0061] That is, regarding the long length film material formed by the first film (210), the second film (220), and the edge heat fusion part (230), a central heat fusion part (240) is formed by heat fusion at intervals, thereby partitioning a plurality of filling parts (201).

[0062] If the space between the central heat-fused sections (240) on both sides is too wide and reinforcement is required in the middle, an additional reinforcing heat-fused section (240a) may be formed in the middle. (Figs. 4 to 7)

[0063] When the central heat-fused portion (240) of the shielding material (200) is located in the through hole (120) of the support member (100), the expanded portion of the shielding material (200) can be positioned in the area between the plurality of support members (100) by filling the filling portion (201) with a filling material. (Figs. 1, 8)

[0065] In the end support member (100A) installed at the end of a plurality of support members (100), an end coupling part (400) is formed to be coupled with the end of a shielding material (200) exposed through a through hole (120) of the end support member (100A). (Fig. 9)

[0066] The end connecting portion (400) is configured to include an end connecting member (410) and a fastening member (420).

[0067] The end connecting member (410) has an "L" shaped cross-sectional structure having a supporting member connecting part (411) that is connected to the outer surface of the supporting member (100) and a shielding material connecting part (412) that is connected to the end of the shielding material (200), and a pair is installed at the top and bottom.

[0068] A fastening member (420), such as a bolt or nut, is jointly connected to the shielding material connecting part (412) of a pair of end connecting members (410) and the end of the shielding material (200).

[0070] The shielding material (200) may be composed of a first shielding material (200a) and a second shielding material (200b) installed at intervals along the vertical direction, thereby enabling a higher shielding effect. (Figs. 10 to 13)

[0071] When a reinforcing membrane material (500) is installed in a truss structure in the area between the first shielding membrane material (200a) and the second shielding membrane material (200b), a more stable structure can be achieved.

[0072] A plurality of support members (100) are configured to include a first support member (100a), a second support member (100b), a third support member (100c), and a fourth support member (100d) installed in a row at spaced intervals.

[0073] The first shielding material (200a) and the second shielding material (200b) are installed to be supported by part or all of the first support member (100a), the second support member (100b), the third support member (100c), and the fourth support member (100d).

[0074] When the first support member (100a) and the third support member (100c) are installed in the first row, and the second support member (100b) and the fourth support member (100d) are installed in the second row spaced parallel to the first row, the first shielding material (200a) is installed in the through hole (120) of the first support member (100a) and the third support member (100c), and the second shielding material (200b) is installed in the through hole (120) of the second support member (100b) and the fourth support member (100d) to form a multilayer structure. (Figs. 10, 11)

[0075] At this time, the reinforcing membrane material (500) is sequentially installed in the through holes (120) of the first support member (100a), the second support member (100b), the third support member (100c), and the fourth support member (100d) to form a truss structure.

[0076] When the through hole (120) of the support member (100) has a configuration including a first through hole (121) and a second through hole (122) formed at a distance from each other, the first shielding material (200a) is coupled to the first through hole (121) and the second shielding material (200b) is coupled to the second through hole (122) to form a multilayer structure. (Figs. 12, 13)

[0077] At this time, the reinforcing membrane material (500) is installed to sequentially penetrate the first through hole (121) of the first support member (100a), the second through hole (122) of the second support member (100b), the first through hole (121) of the third support member (100c), and the second through hole (122) of the fourth support member (100d) to form a truss structure.

[0079] A wall structure (A) for shielding space radiation using the space radiation shielding structure described above may have the following configuration (Figs. 14, 15).

[0080] The support member (100) is installed on the side of the ground or a structure (space base, spacecraft, etc.), and the through hole (120) of the elongated structure is installed so as to face upward and downward.

[0081] The shielding material (200) is installed in the through hole (120) of the upper support member (100) to form an upright structure.

[0082] The wall structure may have a double wall structure including an outer wall (A1), an inner wall (A2), and a wall connecting member (600), which allows for a higher shielding effect.

[0083] The outer wall (A1) is formed by a plurality of support members (100) and a shielding material (200), and the inner wall (A2) is formed with the same structure on the inner side of the outer wall (A1).

[0084] One end of the wall connecting member (600) is connected to the inner side of the support member (100) of the outer wall (A1) by means of a fastener such as a bolt or nut, and the other end is connected to the outer side of the support member (100) of the inner wall (A2).

[0085] The support member (100) may have a plate structure (Fig. 14), a T-shaped cross-sectional structure (Fig. 15), etc., and the wall connecting member (600) may be installed in multiple numbers as needed.

[0087] A roof structure (B) for shielding space radiation using the space radiation shielding structure described above may have the following configuration (Figs. 16 to 18).

[0088] The support member (100) is installed on the upper part of the wall structure (A), and the through hole (120) of the elongated structure is installed so as to face left and right.

[0089] The shielding material (200) is installed in a horizontal structure in the through hole (120) of the upper support member (100).

[0090] When hydrogen (H2) is used as a shielding filler, buoyancy is generated, and a stable structure can be formed by laying regolith (B1) on the upper surface of the shielding membrane material (200).

[0091] The support member (100) may have a plate structure (Fig. 1), an I-shaped cross-sectional structure (Fig. 16), etc.

[0093] A plurality of support members (100) comprises: a central support member (100d) installed in a vertical structure; a left inclined support member (100e) installed to the left of the central support member (100d) and inclined so that its upper end faces left; and a right inclined support member (100f) installed to the right of the central support member (100d) and inclined so that its upper end faces right.

[0094] The spacing member (300) comprises: an upper spacing member (300a) installed at an angle to connect the upper portions of a central support member (100d), a left inclined support member (100e), and a right inclined support member (100f); and a lower spacing member (300b) installed at an angle to connect the lower portions of a central support member (100d), a left inclined support member (100e), and a right inclined support member (100f), and formed to have a shorter length than the upper spacing member (300a).

[0095] When a horizontal reinforcing spacing member (300c) is installed to connect the lower portions of the left inclined support member (100e) and the right inclined support member (100f) as a spacing member (300), a more stable dome-shaped roof structure can be formed.

[0097] Various space radiation shielding structures can be formed by combining a space radiation shielding wall structure (A) and a roof structure (B).

[0098] For example, a space radiation shielding structure can be formed for a base (headquarters), a drilling site, and their movement paths by the above combination. (Fig. 19)

[0099] A wall structure (A) for shielding space radiation can be formed by attaching a support member (100) to the outer surface of a lunar lander and installing a shielding material (200). (Fig. 20)

[0100] A wall structure (A) and a roof structure (B) can be installed on the exterior of the rocket to form a space radiation shielding structure, which can also serve to prevent dust from scattering during the rocket's takeoff and landing. (Fig. 21)
