Description

Permanent water resource exploitation base system in permanent shadow area of moon Technical Field The invention belongs to the field of lunar water resource exploitation, and particularly relates to a permanent water resource exploitation base system in a permanent shadow area of a moon. Background With the expansion of human activities to the universe, the technology of mining and utilizing lunar water resources is becoming a key problem for restricting the human to search and use the moon. Results of lunar soil sample study based on Apollo program retrieval and Chang No. five task retrieval in the United states indicate that the surface of lunar soil particles is loaded with water in the OH form. In the LCROSS detector active impact lunar test, the detection result of the flying dust shows that water molecules possibly exist in lunar soil. Regardless of the form of lunar water ice retention, the heating of lunar soil to extract water in the lunar soil is a main technical idea of in-situ resource exploitation of lunar surface water, firstly, the lunar soil is heated to a molten state so as to expel water in minerals, and secondly, the lunar soil containing ice is heated so as to release the water in the lunar soil. The related technology of moon water ice exploitation is mainly oriented to temporary water resource exploitation detection, and water resource exploitation and moon base construction cannot be considered at the same time. The moon rotation period is long, the included angle between the equatorial plane and the solar energy equatorial plane is small, the solar radiation intensity of the area of the lunar surface which can be irradiated by sunlight is high, and the lunar surface has rich solar energy resources. Meanwhile, as the moon rotation period is longer, the lunar soil temperature of the area of the lunar surface which can be irradiated by sunlight is higher, and water molecules are not easy to be reserved. In a lunar surface permanent shadow area which cannot be irradiated by sunlight, lunar soil keeps a lower temperature throughout the year, so that the lunar soil in the permanent shadow area plays a cold trap role in the migration process of water molecules, the water molecules which jump and migrate are deposited and enriched on the lunar surface in the permanent shadow area, the water molecules deposited on the lunar surface are extremely easy to scatter and lose to the universe or other areas of the lunar surface under the effect of space weathering, the water ice deposited on the lunar surface is buried in the lunar soil due to the temperature fluctuation and the flip action of merle impact, and the strength of the water ice in the lunar soil subjected to space weathering is small, so that the water ice buried in the lunar soil in the lunar surface permanent shadow area is easier to stay up to now. In the initial stage of the construction of the lunar base, key equipment is transported to the moon from the earth through a large-capacity rocket, and meanwhile, the lunar base is constructed by using lunar site resources as much as possible, so that the construction cost can be greatly saved. Under the earth surface environment, energy is conveyed to thousands of households and various industrial and commercial enterprises in an electric mode, so that production and living activities of human beings are greatly facilitated, but a large amount of cables are needed for conveying the energy to a moon permanent shadow area through the solar energy of the moon surface irradiation area through the cables, and the cables simply exposed on the moon surface are extremely easy to damage in the merle impact process, so that great uncertainty is brought to the production activities of the moon surface. Compared with the earth, the pressure of the lunar surface environment is extremely low, the absorption and scattering of sunlight by the thin lunar surface atmosphere are small, and the corresponding energy attenuation and optical modulation influence are small, so that the energy is transmitted in the form of light under the lunar surface environment more advantageously. Because frictional heating between the merle intruding into the moon orbit and the rarefaction atmosphere of the lunar surface is very small, most merle encountered with the moon can directly strike the lunar surface at extremely high movement speed. These random, very energetic merle impact activities seriously threaten the safe operation of the components of the lunar exploration base, especially the personnel residing at the lunar base. The building structure manufactured by directly using lunar soil as an 'epitaxial wall' or welding by using a 3D printing technology has the defect of poor capability of resisting merle collision, and the construction cost of the lunar base is greatly increased by conveying engineering components from the earth to the moon through rockets. The lunar soil is heated to a molten state, so that mois
