Description

Technical Field

[0001] This invention relates to the fields of aerospace and civil engineering, and in particular to a lunar brick-making base based on lunar soil and an in-situ detection method for lunar soil bricks. Background Technology

[0002] Remote sensing and manned lunar exploration have revealed that almost the entire lunar surface is covered by a loosely structured weathered layer—lunar regolith—composed of rock fragments, powder, breccia, impact molten glass, and other materials. Formed in a strongly reducing environment, lunar regolith is primarily composed of silicate and oxide minerals, containing minerals such as anorthite, pyroxene, olivine, ilmenite, and Kripparstein. With a particle size concentrated below 1 cm, lunar regolith exhibits loose and unconsolidated soil characteristics, making it a primary target for future human lunar base construction and resource development.

[0003] The construction of the lunar base requires lunar soil bricks made from lunar soil. Since the bricks are large in weight and volume, the transportation cost between the Earth and the Moon would be very high. Therefore, the preferred solution is to establish a brick-making base on the Moon, using local materials and producing bricks as needed.

[0004] Generally, finished bricks need to undergo physical and environmental performance tests to ensure the safety and durability of buildings. For lunar soil bricks, the physical performance tests are the same as for ordinary bricks, including tests for compressive strength, flexural strength, and impact strength. However, in terms of environmental testing, because the moon is in a vacuum environment, its acceleration g is only 1 / 6 of that on Earth, the daily temperature environment is between -160℃ and 180℃, and there is the influence of cosmic rays.

[0005] Currently, lunar soil has been brought back to Earth. Lunar soil bricks made from it are produced by simulating the lunar environment on Earth and conducting environmental tests. While vacuum and extreme temperature environments are easily simulated, complex environments such as cosmic rays cannot be realistically provided, so the basic properties of the lunar soil bricks cannot be determined. Experiments are also underway to transport lunar soil bricks made on Earth back to the Moon for testing, but since the manufacturing process does not take place on the Moon, there will inevitably be differences between the actual performance data and the real-world data.

[0006] Therefore, this case is brought. Summary of the Invention

[0007] One of the objectives of this invention is to provide an in-situ testing method for lunar soil bricks, so as to achieve comprehensive testing of the performance of lunar soil bricks and ensure their performance in use.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] A method for in-situ detection of lunar regolith bricks, comprising an electrically heated crucible and at least two sets of molds, the method comprising the following steps:

[0010] S1. Use the space shuttle to transport the electric heating crucible and at least two sets of molds to the moon;

[0011] S2. Lunar rover, which has already been performing missions on the moon, collects lunar soil and transports it into a crucible;

[0012] S3. The crucible's electrical energy comes from solar energy conversion. The electrical energy is used to heat and melt the lunar soil inside the crucible, forming a lunar soil slurry.

[0013] S4. The lunar rover pours the molten lunar soil slurry into at least two sets of molds, and the lunar soil slurry cools in the molds to form lunar soil bricks;

[0014] S5. Transport some of the lunar soil bricks back to Earth for testing, and leave the other portion on the Moon for environmental testing.

[0015] Furthermore, the electrical energy of the crucible comes from the photoelectric conversion of the lunar rover's photovoltaic panels and / or from the photoelectric conversion of its own photovoltaic panels.

[0016] A lunar brick-making base based on lunar soil includes a lunar rover for collecting and transporting lunar soil, a melting section, and a curing and casting section;

[0017] The lunar rover will transport the collected lunar soil to the melting section;

[0018] The molten part converts solar energy into high temperatures, causing the lunar soil inside to form a lunar soil slurry;

[0019] Lunar soil slurry enters the curing and pouring section, which is equipped with molds. The lunar soil slurry forms lunar soil bricks through the molds.

[0020] Furthermore, the molten portion utilizes solar energy based on photothermal conversion or photoelectric-thermal conversion.

[0021] The advantages of this invention are: it proposes an in-situ testing method for lunar soil bricks, which are manufactured and tested in a real lunar environment to obtain their true performance data; and it provides a feasible solution for establishing a brick-making base on the moon.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0025] like Figure 2 As shown, this embodiment proposes an in-situ detection method for lunar regolith bricks, including an electrically heated crucible and at least two sets of molds. The detection method includes the following steps:

[0026] S1. Use the space shuttle to transport the electric heating crucible and at least two sets of molds to the moon;

[0027] S2. Lunar rover, which has already been performing missions on the moon, collects lunar soil and transports it into a crucible;

[0028] S3. The crucible's electrical energy comes from solar energy conversion (such as photoelectric conversion from the lunar rover's photovoltaic panels and / or photoelectric conversion from its own photovoltaic panels), and uses electrical energy to heat and melt the lunar regolith inside the crucible to form a lunar regolith slurry;

[0029] S4. The lunar rover pours the molten lunar soil slurry into at least two sets of molds, and the lunar soil slurry cools in the molds to form lunar soil bricks;

[0031] like Figure 1 As shown, this embodiment also proposes a lunar brick-making base based on lunar soil, including a lunar rover for collecting and transporting lunar soil, a melting section, and a curing and casting section; the lunar rover transports the collected lunar soil to the melting section; the melting section converts solar energy into high temperature, causing the internal lunar soil to form lunar soil slurry; the lunar soil slurry enters the curing and casting section, which is equipped with molds, and the lunar soil slurry forms lunar soil bricks through the molds.

[0032] The molten section is based on photothermal conversion or photoelectric thermal conversion, utilizing solar energy. The structure of photothermal conversion can refer to the structure of a molten salt solar power plant, where solar energy is aggregated through mirrors to achieve high-temperature melting. Photoelectric thermal conversion converts light energy into electrical energy, and then electrical energy into heat energy.
