Description

Technical Field

[0001] This invention belongs to the field of lunar water resource extraction, and in particular relates to a permanent water resource extraction base system in the permanently shadowed area of ​​the moon. Background Technology

[0002] As human activities expand into outer space, the technology for extracting and utilizing lunar water resources is becoming a key issue restricting human exploration and use of the moon. Research results based on lunar regolith samples returned by the Apollo program and the Chang'e 5 mission indicate that water in the form of OH exists on the surface of lunar regolith particles. Detection of dust generated during the LCROSS probe's active impact test on the moon suggests the possible presence of water molecules in the lunar regolith. Regardless of the form of lunar water ice, heating the lunar regolith to extract water is the mainstream technical approach for in-situ lunar surface water resource extraction. This involves two methods: first, heating the lunar regolith to a molten state to force water out of the minerals; and second, heating lunar regolith containing ice to release water. Currently, lunar water ice extraction technologies primarily focus on temporary water resource exploration and cannot simultaneously consider water resource extraction and lunar base construction.

[0003] The Moon's long rotation period and small angle between its equatorial plane and the Sun's ecliptic plane result in higher solar radiation intensity in sunlit areas, giving the Moon abundant solar energy resources. However, due to the Moon's long rotation period, the lunar regolith in sunlit areas is warm, which is unfavorable for water molecule retention. In permanently shadowed regions of the Moon, the regolith maintains a consistently low temperature, acting as a cold trap for water molecule migration. This allows water molecules to accumulate and deposit in these shadowed areas. Water molecules deposited on the Moon are easily dispersed into space or other parts of the Moon by space weathering. Temperature fluctuations and the turbulent effects of meteorite impacts bury water ice within the lunar regolith. Water ice within the regolith is less susceptible to space weathering, making it more likely to have survived to this day in permanently shadowed regions.

[0004] In the initial stages of lunar base construction, transporting key equipment from Earth to the Moon using high-capacity rockets, while utilizing existing lunar resources as much as possible, can significantly reduce construction costs. On Earth, transmitting energy as electricity to households and businesses greatly facilitates human production and daily life. However, transmitting solar energy from sunlit areas to permanently shadowed areas on the Moon requires a large number of cables. These cables, simply exposed on the lunar surface, are highly susceptible to damage from meteorite impacts, introducing significant uncertainty to lunar production activities. Compared to Earth, the lunar environment has extremely low pressure, and the thin lunar atmosphere absorbs and scatters sunlight very little, resulting in minimal energy attenuation and optical modulation. Therefore, transmitting energy as light on the lunar surface is far more advantageous.

[0005] Because meteorites entering lunar orbit generate very little heat through friction with the thin lunar atmosphere, most meteorites that encounter the Moon impact the lunar surface directly at extremely high speeds. These random, high-energy meteorite impacts seriously threaten the safe operation of all components of the lunar exploration base, especially the safety of personnel stationed there. Buildings constructed directly from lunar regolith or using 3D printing technology have poor resistance to meteorite impacts, and transporting engineering components from Earth to the Moon via rockets significantly increases the construction cost of the lunar base. Heating lunar regolith to a molten state releases water, and the resulting glassy material after cooling possesses high strength, offering numerous possibilities for lunar base construction. Therefore, lunar water resource extraction and utilization technologies involve solving engineering problems related to lunar surface energy transmission, heat release water molecule capture, and lunar base construction. Summary of the Invention

[0006] The purpose of this invention is to provide a base system suitable for water resource extraction in permanently shadowed areas of the moon.

[0007] The technical solution adopted in this invention is as follows:

[0009] The focusing mirror is positioned within the illuminated area of ​​the near-permanent shadow region. It is mounted on a focusing mirror bracket, which is used to adjust the horizontal and vertical angles of the focusing mirror.

[0010] The focusing collimator is connected to the condensing lens via a focus catcher. The focus catcher is used to adjust the focusing collimator so that it is at the focal point of the light gathered by the condensing lens. The focusing collimator is formed by stacking multiple sets of first focusing units in sequence. Each first focusing unit contains an adjustable first lens element.

[0011] The first set of omnidirectional optical transceivers is connected to the focusing collimator. This first set of omnidirectional optical transceivers includes a flange base and four sets of right-angle optical energy bends connected in sequence. The flange base is connected to the focusing collimator. A solar power plane mirror, which serves both solar power generation and light reflection, is installed at the bend of each right-angle optical energy bend. The flange base is rotatably connected to the nearest right-angle optical energy bend, and adjacent right-angle optical energy bends are rotatably connected to each other. Driving components are installed between the flange base and the nearest right-angle optical energy bend, as well as between adjacent right-angle optical energy bends. These driving components are used to drive the right-angle optical energy bends to rotate.

[0012] Within the water sampling base in the permanent shadow pit, a second set of universal optical transceivers, a third set of universal optical transceivers, and a light power distributor were fixed using initial simple supports. The second and third sets of universal optical transceivers had the same structure as the first set.

[0013] The light energy distributor includes multiple sets of second focusing units, each containing a focusable second lens.

[0014] In-situ water resource thermal extraction piles or water resource thermal extraction systems are set up in the water extraction base within the permanent shadow pit, and high-energy light emitted by the light energy distributor is irradiated onto the in-situ water resource thermal extraction piles or water resource thermal extraction systems.

[0016] A further technical solution is that the water-absorbing pack has a porous quicklime at its center and montmorillonite on the outside. Water molecules undergo chemical adsorption on the surface of the porous quicklime and physical adsorption on the surface of the montmorillonite particles.

[0017] A further technical solution is that the water resource thermal extraction system includes a heat release vessel and a water absorption vessel. The main body of the heat release vessel is a high-temperature resistant vessel body. The lower part of the heat release vessel has three vessel body support legs. The bottom of the heat release vessel is provided with a drain port for discharging molten lunar soil. The top of the heat release vessel is provided with a gas transmission pipe for discharging water-containing gas. The side of the heat release vessel is provided with a glassy light energy window that allows high-energy light to enter and a material port for loading materials such as lunar soil. The gas transmission pipe is connected to the air inlet of the water absorption vessel. The lower part of the water absorption vessel is equipped with montmorillonite that can physically adsorb water molecules, and the upper part is equipped with porous quicklime that can chemically adsorb water molecules. The top of the water absorption vessel is provided with a residual gas port to facilitate the discharge of other gases. The air inlet of the water absorption vessel is located below the montmorillonite.

[0018] A further technical solution involves the water resource thermal extraction system also including bricklaying molds and waist-shaped molds.

The bottom of the upper focusing mirror support is provided with a steering stepper motor, and the steering stepper motor has a support rotation pinion gear. The support rotation pinion gear is connected to the support rotation gear ring for transmission. The focusing mirror is hinged to the top of the upper focusing mirror support, and a first telescopic rod assembly is connected between the focusing mirror and the upper focusing mirror support. One end of the first telescopic rod assembly is hinged to the focusing mirror, and the other end of the first telescopic rod assembly is hinged to the upper focusing mirror support.

[0020] A further technical solution is that the focus capture device includes a capture device flange and a second telescopic rod assembly, three lower ball head supports are provided on the focusing lens, and three upper ball head supports corresponding to the lower ball head supports are provided below the capture device flange. The upper ball head supports and the corresponding lower ball head supports are connected by the second telescopic rod assembly.

[0021] A further technical solution involves a focusing collimator formed by sequentially connecting a focusing collimator flange, multiple sets of first focusing units, and an end flange using a first series of stacked screws. The main body of the first focusing unit is a focusing mother component, which has stacked screw holes along the column direction inside. One end of the focusing mother component is a circular tube with multiple lens rails. The first lens is placed inside the circular tube. The other end of the focusing mother component is a focusing motor flange with a motor mount. A focusing stepper motor is fixed on the motor mount, and the output shaft of the focusing stepper motor is coaxially fixed. The focusing gear has a focusing cylinder fitted on it. The first lens has a focusing tooth at a position corresponding to the lens rail. The focusing tooth is located inside the lens rail at the corresponding position. A lens screw rail is provided on the outside of the focusing tooth. The focusing cylinder has a focusing screw rail inside for driving the first lens to move back and forth. A focusing gear ring is provided on the outside of the focusing cylinder at a position corresponding to the focusing gear. The focusing gear and the focusing gear ring are connected in a transmission. Thrust cylindrical roller bearings are provided on the circular cross-sections at both ends of the focusing cylinder that contact the focusing motor flange. The focusing collimator flange and the capture device flange are connected by bolts.

[0022] A further technical solution involves connecting the flange base to its nearest solar-powered right-angle bend and to two adjacent solar-powered right-angle bends via rotating components. These rotating components include a limiting misalignment platform, a limiting cone, pipe limiting teeth, a pipe limiting groove, and a limiting hoop. The limiting misalignment platform and the limiting cone are located at the upper end of the flange base and the tail end of the solar-powered right-angle bend, respectively. The pipe limiting teeth and the pipe limiting groove are located at the front end of the solar-powered right-angle bend. Limiting hoops are rotatably installed at the connection points between the flange base and the solar-powered right-angle bend, as well as at the connection points between two adjacent solar-powered right-angle bends. The interior of the limiting hoop has a conical slope at the position corresponding to the limiting cone, and the conical slope... The flange base is equipped with tapered roller bearings. The limiting hoop has a hoop limiting tooth and a hoop limiting groove inside. The hoop limiting tooth is located inside the pipe limiting groove on the corresponding optical energy right-angle bend, and the pipe limiting tooth is located inside the hoop limiting groove of the corresponding limiting hoop. The other end of the flange base is provided with a flange. The drive assembly includes a steering gear ring located at the upper end of the flange base and the tail end of the optical energy right-angle bend, and an optical path stepper motor located at the front end of the optical energy right-angle bend. A steering pinion is fixed on the output shaft of the optical path stepper motor. The steering pinion is connected to the steering gear ring at the corresponding position. The flange of the first set of universal optical transceivers is connected to the end flange by bolts.

[0023] A further technical solution is that the light energy distributor is formed by connecting a connecting cylinder and multiple sets of second focusing units through a second series of stacked screws, and the connecting cylinder of the light energy distributor is connected to the light energy right-angle bend at the end of the third set of universal optical transceivers.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] (1) The present invention has high energy utilization rate. On the one hand, by setting up in-situ water resource thermal mining piles, the solar energy is used to directly heat the lunar soil or the in-situ water resource thermal mining piles, reducing the loss caused by energy form conversion. On the other hand, by setting up a water resource thermal mining system, molten lunar soil can be produced. The molten lunar soil is directly loaded into the brick-making mold and the waist mold, which makes efficient use of energy. In the present invention, the exhaust gas port of the water-absorbing vessel of the industrial water mining device can also be connected to other gas collection devices such as rare gas and methane gas, realizing the engineering effect of multiple outputs from one heating, which greatly saves resources.

[0026] (2) The main mechanical components used in this invention have simple structure, high reliability, long service life, easy replacement and maintenance, and each component is repairable. After experiencing natural disasters such as meteorite impacts, it is easier to find replacement parts and to find and solve faults.

[0027] (3) The present invention can capture trace amounts of water. In the present invention, montmorillonite and quicklime are used as physical adsorbents and chemical adsorbents, respectively, which can capture trace amounts of water released from lunar soil in a timely manner. Compared with engineering devices that use natural condensation to capture water, it can still effectively capture water when the concentration of water molecules is very small, which indirectly increases the water collection efficiency.

[0028] (4) This invention utilizes the advantages of the lunar surface environment having fewer gas molecules, resulting in less light energy attenuation and optical modulation, to transmit energy, thus avoiding the high cost of transmitting energy from Earth to the Moon via power transmission cables launched by a carrier rocket.

[0029] (5) The bricks and slender waists cast from molten lunar soil proposed in this invention can be used to build lunar surface structures. They have the advantages of strong resistance to meteorite impact and easy repair after being impacted.

[0030] (6) In this invention, the first set of universal optical transceivers transmits the sunlight from the focusing collimator to other concentrating mirrors or lunar surface water resource extraction bases. Transmitting the sunlight to other concentrating mirrors can achieve the series and parallel connection between concentrating mirrors. The second set of universal optical transceivers is fixed on the top of the initial simple support or brick-built arched protective cover to receive the high-energy light transmitted by the first set of universal optical transceivers. The third set of universal optical transceivers is fixed on the top of the initial simple support or brick-built arched protective cover to receive the high-energy light transmitted by the second set of universal optical transceivers. A light energy distributor is set at its light energy outlet position. The high-energy light after being focused by the light energy distributor is adjusted in direction by the third set of universal optical transceivers and transmitted to the point of need. The use of the first set of universal optical transceivers, the second set of universal optical transceivers and the third set of universal optical transceivers gives more freedom in the direction of high-energy light transmission and increases the flexibility of the construction of the lunar water extraction base.

[0031] (7) The high-energy light transmitted by the focusing collimator is a parallel light with a larger optical path diameter. The light energy distributor in this invention further focuses the high-energy light at the front end of the energy demand point and places the focal point of the focused high-energy light on the heat-absorbing fins on the surface of the lunar soil or the upper surface of the heat-conducting pile in the heat release vessel of the industrial thermal mining system.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] like Figures 1-15 As shown.

[0049] A permanent water resource extraction base system in a lunar permanently shadowed area includes a cluster of focusing mirrors 1, a focusing collimator 4, a first set of universal optical transceivers 5, a second set of universal optical transceivers 96, a third set of universal optical transceivers 97, and a light energy distributor 6. The focusing mirrors 1 are positioned in the illuminated area of ​​the near-permanent shadowed region and are mounted on a focusing mirror support 2. The focusing mirror support 2 is used to adjust the angle of the focusing mirrors 1 in the horizontal and vertical directions. The focusing collimator 4 is connected to the focusing mirrors 1 through a focus catcher 3, which is used to adjust the focusing collimator 4 to a position where it is positioned correctly. The focal point of the light gathered by the focusing mirror 1 is formed by the collimator 4, which is formed by stacking multiple sets of first focusing units 32 in sequence. Each first focusing unit 32 contains a first focusing lens 36. The first set of universal optical transceivers 5 is connected to the collimator 4. The first set of universal optical transceivers 5 includes a flange base 52 and four sets of light energy right-angle bends 51 connected in sequence. The flange base 52 is connected to the collimator 4. A plane mirror 55 is set at the bend of the light energy right-angle bend 51. The plane mirror 55 can be a plane mirror that reflects light, or it can be a solar mirror that combines solar power generation and light reflection. The power generation plane mirror, flange base 52, is rotatably connected to the nearest right-angle bend in the light energy tube 51. Two adjacent right-angle bends in the light energy tube 51 are rotatably connected to each other. Driving components are installed between the flange base 52 and the nearest right-angle bend in the light energy tube 51, as well as between two adjacent right-angle bends in the light energy tube 51. These driving components are used to drive the right-angle bends in the light energy tube 51 to rotate. In the water collection base within the permanent shadow pit, the second set of universal optical transceivers 96, the third set of universal optical transceivers 97, and the light energy distributor 6 are fixed by an initial simple bracket 69. The second set of universal optical transceivers 96 and the third set of universal optical transceivers... The transceiver 97 has the same structure as the first set of universal optical transceivers 5. The optical energy right-angle bend 51 at the end of the first set of universal optical transceivers 5 is connected in sequence to the second set of universal optical transceivers 96, the third set of universal optical transceivers 97 and the optical energy distributor 6. The optical energy distributor 6 includes multiple sets of second focusing units 99. The second focusing unit 99 is equipped with a second lens 100 that can be adjusted for focus. An in-situ water resource thermal mining pile 8 or a water resource thermal mining system 9 is set in the water collection base in the permanent shadow pit. The high-energy light 50 emitted by the optical energy distributor 6 irradiates the in-situ water resource thermal mining pile 8 or the water resource thermal mining system 9.

[0050] In use, the energy-concentrating mirror 1 in the non-permanent shadow area transmits energy one-to-one to the permanent shadow area. Multiple energy-concentrating mirrors 1 can also be set at the edge of the permanent shadow area. By connecting multiple sets of energy-concentrating mirrors 1 in series and parallel, the power of light energy transmitted to the permanent shadow area can be effectively increased. The energy-concentrating mirror support 2 can rotate 360° in the horizontal plane. With the assistance of the first telescopic rod assembly 21 described below, the energy-concentrating mirror 1 can rotate in the vertical plane. By adjusting the orientation of the mirror surface of the energy-concentrating mirror 1, sunlight can be captured to the maximum extent. The focus catcher 3 relies on the second telescopic rod assembly 98 described below to adjust the position of the focusing collimator 4, so that the focusing collimator 4 finds the focal point of the light gathered by the energy focusing lens 1. Each component of the focus catcher 3 has a small coefficient of thermal expansion. The focusing collimator 4 uses four sets of first focusing units 32 with the first lens 36 being a plano-convex lens 48 and one set of first focusing units 32 with the first lens 36 being a biconvex lens 49 to focus sunlight into high-energy light 50. In the early stage of the construction of the water sampling base in the permanent shadow pit, the initial simple support 69 is used to fix the second set of universal optical transceivers 96, the third set of universal optical transceivers 97 and the light energy distributor 6 for operation. The initial simple support 69 is formed by three equal-length lightweight support legs 72 fixed to the support flange 71 by ball joints 70. A second set of universal optical transceivers 96 and a third set of universal optical transceivers 97 are respectively installed on the upper and lower sides of the bracket flange 71 for optical energy transmission. The optical energy output end of the third set of universal optical transceivers 97, which is located at the lower part of the bracket flange 71, is equipped with an optical energy distributor 6. The flange base 52 of the second set of universal optical transceivers 96 and the third set of universal optical transceivers 97 are connected to the initial simple bracket 69 by bolts.

[0051] A rotatable, light-tracking focusing mirror support 2 enables the focusing mirror 1 to effectively capture sunlight. A focusing collimator 4, formed by multiple sets of different convex lenses and biconvex lenses, adjusts the sunlight into high-energy, straight rays. A first set of universal optical transceivers 5 projects the light energy to a designated location within a permanently shadowed crater, and a second set of universal optical transceivers 96 receives the light in the target area. A third set of universal optical transceivers 97 adjusts the light direction to the desired point. At the end of the third set of universal optical transceivers 97, a light distributor 6 adjusts the high-energy collimated light into a point source at the desired point for utilization. This not only provides greater freedom in the projection and reception of light energy but also allows for more precise direction adjustment, better adapting to the complex terrain of the lunar surface. Furthermore, when the plane mirror 55 is designed to also generate electricity, it can also... Using high-energy light 50 to generate electricity is more efficient than directly receiving solar energy. In this invention, the deep lunar soil in the permanent shadow pit is heated in situ by the in-situ water resource thermal extraction pile 8, causing the water ice in the lunar soil to sublimate rapidly. The water molecules released by the lunar soil are captured on the surface of montmorillonite 79 and porous quicklime 78 through the air inlet 80 on the surface of the heat-conducting pile 76. The water resource thermal extraction system 9 can heat the lunar soil to a molten state, causing the chemically adsorbed water in the lunar soil to be released and finally captured by the water-absorbing agent pack 77 formed by montmorillonite 79 and porous quicklime 78 in the water-absorbing vessel 82. After the molten lunar soil is put into the brick-building mold 92 and the waist-shaped mold 93 and cooled, it forms bricks 94 and waist-shaped molds 95. This building material has the advantages of high strength and easy interlocking. At the same time, since bricks 94 and waist-shaped molds 95 are by-products of industrial water resource extraction on the lunar surface, they have the advantages of low cost and high renewability.

[0052] like Figure 13 As shown, the in-situ water resource thermal extraction pile 8 has heat-absorbing fins 75 at its top, and a heat-conducting pile 76 that can be driven into the soil at its bottom. The heat-conducting pile 76 contains a water-absorbing chemical pack 77, and its surface has air inlets 80 that allow water molecules to enter. The surface of the heat-absorbing fins 75 at the top of the in-situ water resource thermal extraction pile 8 is coated with a high solar energy absorption ratio coating, such as the Zijing super-limit coating made of the same material and process as the Zijing tube in a solar water heater, which can better absorb heat.

[0053] The water-absorbing pack 77 has a porous quicklime 78 at its center and montmorillonite 79 on the outside. Water molecules undergo chemical adsorption on the surface of the porous quicklime 78 and physical adsorption on the surface of the montmorillonite 79 particles.

[0054] like Figure 14As shown, the water resource thermal extraction system 9 includes a heat release vessel 81 and a water absorption vessel 82. The main body of the heat release vessel 81 is a high-temperature resistant vessel body 84. The lower part of the heat release vessel 81 has three vessel body support legs 85. The bottom of the heat release vessel 81 is provided with a drain port 86 for discharging lunar soil molten liquid. The top of the heat release vessel 81 is provided with a gas transmission pipe 87 for discharging water-containing gas. The side of the heat release vessel 81 is provided with a glassy light energy window 88 that allows high-energy light 50 to enter and a material port 89 for loading materials such as lunar soil. The gas transmission pipe 87 is connected to the air inlet of the water absorption vessel 82. The lower part of the water absorption vessel 82 is provided with montmorillonite 79 that can physically adsorb water molecules, and the upper part is provided with porous quicklime 78 that can chemically adsorb. The top of the water absorption vessel 82 is provided with a residual gas port 90 to facilitate the discharge of other gases. In order to prevent the water absorption vessel 82 from overheating, heat dissipation fins 91 are provided on its surface to assist in heat dissipation. The air inlet of the water absorption vessel 82 is located below the montmorillonite. The water resource thermal extraction system 9 also includes bricklaying mold 92 and waist-shaped mold 93.

[0055] The water resource thermal extraction system 9 is formed by a water molecule precipitation device, a heat release vessel 81, and a water molecule trapping device, a water absorption vessel 82. The molten lunar soil output from the drain port 86 at the bottom of the heat release vessel 81 in the water resource thermal extraction system 9 can be loaded one by one into the brick-building mold 92 and the waist-shaped mold 93. After the molten lunar soil in the mold cools down, it can form bricks 94 and waist-shaped molds 95 for building an arched protective cover. The bricks 94 are connected by the waist-shaped molds 95 and can be used to build a brick-built arched protective cover 7. This construction method effectively avoids the disadvantage of the lack of cementing material for bricks 94 in the lunar environment, which leads to the instability of the structure.

[0056] like Figure 2 and Figure 3 As shown, the focusing mirror support 2 includes an upper focusing mirror support 12 and a lower focusing mirror support 11. The bottom of the lower focusing mirror support 11 is provided with a fixed flange 13 that connects to the lunar surface base. The upper end of the lower focusing mirror support 11 is provided with a support rotation gear ring 10, and the upper end of the lower focusing mirror support 11 is rotatably connected to the upper focusing mirror support 12. The bottom of the upper focusing mirror support 12 is provided with a steering stepper motor 16, and a support rotation pinion 17 on the steering stepper motor 16 is connected to the support rotation gear ring 10. The focusing mirror 1 is hinged to the top of the upper focusing mirror support 12, and a first telescopic rod assembly 21 is connected between the focusing mirror 1 and the upper focusing mirror support 12.

[0057] The focusing mirror 1 can rotate 360 ​​degrees in the horizontal direction by the steering stepper motor 16 on the upper focusing mirror bracket 12 and the bracket rotation gear ring 10 on the lower focusing mirror bracket 11. The first telescopic rod assembly 21 can be an existing electric push rod, or it can be a structure formed by a telescopic rod sleeve 22, a telescopic rod stepper motor 24 with a telescopic rod drive gear 23, and a telescopic rod 26 with a rack 25. By driving the telescopic rod drive gear 23 to rotate by the telescopic rod stepper motor 24, the telescopic rod 26 can be moved to adjust the angle of the focusing mirror 1 in the vertical direction. The upper end of the lower focusing mirror support 11 is rotatably connected to the upper focusing mirror support 12. This can be achieved by providing a slewing bearing at the upper end of the lower focusing mirror support 11 and the upper focusing mirror support 12, or by providing a thrust ball bearing 14 and a cylindrical roller bearing 15 at the inner side of the tube corresponding to the slewing gear ring 10 of the support. The bottom of the upper focusing mirror support 12 is provided with a support shaft 18 and a bearing misalignment 19 that are inserted into the lower focusing mirror support 11. The top of the upper focusing mirror support 12 is provided with a movable hinge support 20, through which the focusing mirror 1 and the focusing mirror support 2 are hinged.

[0058] The focus catcher 3 includes a catcher flange 28 and a second telescopic rod assembly 98. Three lower ball head supports 27 are provided on the focusing lens 1, and three upper ball head supports 29 corresponding to the lower ball head supports 27 are provided below the catcher flange 28. The upper ball head supports 29 are connected to their corresponding lower ball head supports 27 via the second telescopic rod assembly 98. The catcher flange 28 is used to connect the focusing collimator 4. The position of the catcher flange 28 can be adjusted via the second telescopic rod assembly 98, thereby adjusting the position of the focusing collimator 4.

[0059] like Figure 4As shown, the focusing collimator 4 is formed by sequentially connecting the focusing collimator flange 31, multiple sets of first focusing units 32, and the end flange 33 using a first cascade screw 30.

Thrust cylindrical roller bearings 47 are provided on the circular cross-sections at both ends of the focusing cylinder 44 that contact the focusing motor flange 39. The focusing collimator flange 31 and the capture device flange 28 are connected by bolts. In this invention, the first focusing unit 32 can hold first lenses 36 with different parameters. This invention uses four sets of first focusing units 32 with first lenses 36 of plano-convex lenses 48 and one set of first focusing units 32 with first lenses 36 of biconvex lenses 49, so that the sunlight collected by the focusing mirror 1 is adjusted into high-energy light rays 50 that can be transmitted in a straight line. The parameters of the first lens 36 need to be further specifically designed according to the engineering application scenario in specific implementations.

[0060] Each first focusing unit 32 drives the focusing gear 41 to rotate via the focusing stepper motor 40. The focusing gear 41 can drive the focusing cylinder 44 to rotate. With the cooperation of the lens rail 43 and the focusing rail 45, the first lens 36 moves along the lens rail 37, thereby achieving focusing.

The sub-bearing 66 and the limiting clamp 57 are provided with clamp limiting teeth 67 and clamp limiting grooves 68. The clamp limiting teeth 67 are located inside the pipe limiting grooves 62 on the corresponding optical energy right-angle bend 51, and the pipe limiting teeth 61 are located inside the clamp limiting grooves 68 of the corresponding limiting clamp 57. The flange 53 is provided at the other end of the flange base 52.

The flange 53 of the first set of universal optical transceivers 5 is connected to the end flange 33 by bolts.

[0062] Driven by the optical path stepper motor 56, the universal optical transceiver can transmit sunlight in a wider range of directions; the solar power generation plane mirror in the universal optical transceiver 5 is set at the bend of the optical energy right angle bend tube 51, and the angle between the normal of its mirror surface and the tube axis is 45°. The solar power generation plane mirror is formed by a plane mirror with a solar power generation panel on its back.

The connecting cylinder 73 of the light energy distributor 6 is connected to the light energy right-angle bend 51 at the end of the third set of universal optical transceiver 97. The second focusing unit 99 has the same structure as the first focusing unit and adopts the same focusing method. The connecting cylinder 73 of the light energy distributor 6 is connected to the limiting cone tube 60 of the light energy right-angle bend 51 at the end of the universal optical transceiver 5 through the limiting clamp 57. The connecting cylinder 73 is also provided with a tube limiting groove 62 and a tube limiting tooth 61. The second focusing unit 99 has a focusable second lens 100. A second focusing unit 99 using the second lens 100 as a biconvex lens 49 or a second focusing unit 99 using the second lens 100 as a concave-convex lens 74 is also possible. The high-energy light beam 50 can be further focused to deliver it to the lunar soil surface where the in-situ water resource thermal extraction pile 8 or water resource thermal extraction system 9 needs to be heated. Alternatively, more sets of second focusing units 99 can be used in conjunction with more second lenses 100 to further adjust the high-energy light beam 50.

[0064] This invention utilizes the advantages of low solar energy attenuation and minimal light modulation effect on the lunar surface to transport energy in the form of sunlight to the permanently shadowed areas of the moon. Based on the engineering environmental conditions of low water content in lunar soil and low atmospheric pressure on the lunar surface, an adsorption method is used to collect water discharged from the lunar soil into water-collecting minerals. The molten lunar soil slag after water collection is poured into a brick-making mold 92, and finally cooled to form bricks 94 made of a glassy material. Due to the lack of lunar soil binders on the lunar surface, the bricks 94 are interlocked by narrow waists 95. Structures constructed using these bricks 94 exhibit strong resistance to meteorite impacts, high durability, and high repairability after meteorite impacts. The lunar permanently shadowed area water resource extraction base system proposed in this invention comprehensively solves the engineering problems of lunar surface energy transmission, heat-released water molecule capture, and lunar base construction.

[0065] The above are merely preferred embodiments of the present invention.
