Description

Technical Field

[0001] The present invention relates to an in-situ, non-cemented, integrated construction method for a lunar surface and deep lunar base, and belongs to the technical field of space base construction and space mining. Background Art

[0002] The Moon, Earth's only natural satellite, represents humanity's first step toward space exploration and development. Lunar exploration is a practical manifestation of humanity's continued exploration and development of space, the development and utilization of space resources and energy, and the unfolding of the formation and evolution of celestial bodies.

[0003] The construction of a lunar surface base in the lunar exploration project is the basis for in-situ acquisition of lunar resources and deep space exploration. However, the extreme environment of the moon (such as high vacuum, low gravity, large temperature differences, strong radiation, etc.) places extremely high demands on the stability and durability of the base structures. Existing technical concepts mostly rely on adhesive materials (such as cement) transported by space vehicles, which face challenges in environmental adaptability, high engineering complexity and huge costs. Some technical concepts further involve the unbonded splicing of in-situ sintered lunar soil bricks. However, in-situ sintering will change the original properties of the lunar soil under high temperature conditions, which will greatly weaken the radiation protection and temperature maintenance capabilities of the base. In addition, a base based solely on the lunar surface can only meet the needs of unmanned lunar exploration projects such as short-term observations and signal relay services.

[0004] The construction of a deep lunar base within the lunar exploration program is fundamental to astronauts' long-term lunar presence, work, and life. The deep lunar surface provides excellent shielding from cosmic rays and intense solar flares, significantly reducing health risks for astronauts. Due to the extremely low thermal conductivity of lunar regolith, the temperature in deep lunar space can be maintained at a constant -20°C, far superior to the dramatic day-night temperature swings on the lunar surface (-180°C to 120°C). This significantly reduces energy consumption in the temperature control system and makes it suitable for astronauts' work and life. Furthermore, utilizing the ultra-quiet environment of the deep lunar surface to deploy high-precision instruments (such as gravitational wave detectors and dark matter observation facilities) can mitigate lunar surface vibrations and electromagnetic interference, enabling high-precision aerospace research. While establishing a base deep within the moon offers natural protection, and using deep lunar lava caves or artificial caves (deep >10 meters) as base space is also feasible, a reasonable construction method currently lacks. Some scholars have proposed constructing deep lunar bases using 3D-printed arched load-bearing piles from lunar regolith. This technology requires complex equipment, a certain amount of binder, and even a small amount of sintering. At present, there is a lack of integrated construction technology for lunar surface and deep lunar bases worldwide, and it is impossible to achieve in-situ, non-bonded "surface-inside coordination" of lunar base functions. If the existing proposed method is used to build a deep lunar base, the economic cost of a single base construction will be greatly increased, which will bring serious constraints to subsequent in-situ resource mining and scientific research.

[0005] The theory of thermal rock fracturing has been a hot topic in the field of rock crushing since the 1830s. High-temperature flame jet surface heating is one such method. At the appropriate flame temperature (below the melting point), the rock surface is instantly heated, and a thin layer of the surface undergoes thermal exfoliation due to thermal stress compression. The exfoliated flakes always flake and eject perpendicularly to the heated surface. After one layer of rock is exfoliated, a new layer forms, and the same process occurs again, causing the exfoliation depression to extend further into the rock. Simultaneously, the rock beneath the thin surface compression layer is subjected to associated tensile stress. When the tensile stress exceeds the tensile strength, tensile cracks appear perpendicular to the heated surface, inhibiting the thermal exfoliation process and achieving the desired rock cutting effect.

[0006] Therefore, how to provide a new construction method based on the thermal fracture mechanism of rock, by controlling the thermal exfoliation process of high-temperature flame jet rock breaking and the accompanying tensile thermal fracture process, to achieve the in-situ non-cemented integrated construction of the lunar surface and deep lunar base, and effectively save construction costs, is the research direction required by the present invention. Summary of the Invention

[0007] In response to the problems existing in the above-mentioned prior art, the present invention provides a method for in-situ, non-cemented, integrated construction of the lunar surface and deep lunar base. Based on the thermal fracture mechanism of rock, the method controls the thermal exfoliation process of high-temperature flame jet rock breaking and the accompanying tensile thermal fracture process to achieve in-situ, non-cemented, integrated construction of the lunar surface and deep lunar base, effectively saving construction costs.

[0008] To achieve the above objectives, the present invention adopts a technical solution: a method for in-situ, non-cemented, integrated construction of a lunar surface and deep lunar base, comprising the following steps:

[0009] Step 1: Map the spatial distribution of deep lava caves on the Moon and select a deep lava cave as a deep base. Based on the location of the deep base, determine the location of the lunar surface base. Simultaneously, prepare for the launch of the lunar rover on Earth.

[0010] Step 2: Launching a lunar rover assembly for lunar base construction from Earth to the Moon. The rover assembly includes a water-ice electrolysis rover, a thermal rock-breaking rover, and a hoisting-and-transporting rover. The hoisting-and-transporting rover is used to transport the thermal rock-breaking rover to the desired location in the deep lava cave and to load and unload the water-ice electrolysis rover assembly.

[0011] Step 3: Start the water ice electrolysis lunar rover. After the electrolysis generates a stable flow of hydrogen and oxygen, the hydrogen and oxygen are transported to the thermal rock-breaking lunar rover. Then, the thermal rock-breaking lunar rover is started. A high-temperature flame is generated by the mixed combustion of hydrogen and oxygen near the entrance of the deep lava cave. The target area is subjected to thermal exfoliation directional deep drilling to form a fixed hole for the hoisting-transporting lunar rover to carry out heavy lifting-assembly operations. The hoisting-transporting lunar rover is controlled to move to the fixed hole to complete the fixation of the hoisting-transporting lunar rover.

[0012] Step 4: Control one of the thermal rock-breaking lunar rovers to move to the lunar surface base to perform thermal rock-breaking construction on the lunar surface rocks; hoist and transport the lunar rover to transport the other thermal rock-breaking lunar rover into the deep lava cave to perform thermal rock-breaking construction on the deep base;

[0013] Step 5: Synchronously start the two thermal rock-breaking lunar rovers in step 4 and control their operating status in real time. One of the thermal rock-breaking lunar rovers uses jet flames to thermally cut the lunar surface rocks to form topological interlocking structures and topological interlocking grooves on the walls of the lunar surface base. The other thermal rock-breaking lunar rover uses jet flames to directional drill deep lava caves and shape the lava cave walls to form a deep base.

[0014] Step 6: After the lunar rock cutting operation is completed, a portion of the topological interlocking structure formed by thermal cutting on the lunar surface is used as the wall of the lunar surface base by hoisting and building a lunar rover, so that it matches the topological interlocking groove. After the thermal rock-breaking lunar rover in the deep lava cave space completes the directional extension construction of the connecting channel between the deep base and the lunar surface base, the thermal rock-breaking lunar rover is lifted to the lunar surface by hoisting and building a lunar rover, and the other portion of the topological interlocking structure is hoisted and fixed to the upper part of the lunar surface base wall to form the top of the lunar surface base;

[0015] Step 7: Use the hoisting-built lunar rover to move a portion of the topological interlocking structure to the cave entrance of the deep base to cover it. After completion, stop all lunar rover operations and complete the integrated construction process of the lunar surface base and the deep base.

When the support platform needs to be limited, the three-way fork barbed sling extends from the sling control warehouse to the fixing hole on the lunar surface to achieve relative fixation of the support platform; the energy supply mechanism includes solar panels and hydraulic telescopic control rods, the hydraulic telescopic control rods are vertically installed on the support platform, and the solar panels are installed on the upper part of the hydraulic telescopic control rods to supply electricity for the entire lifting and transporting lunar rover; the hydraulic telescopic control rods are used to adjust the height of the solar panels relative to the support platform; the controller is used to control the operation of the electric roller, lifting mechanism, limiting mechanism and energy supply mechanism.

[0017] Furthermore, in step 1, the location for constructing the lunar surface base is determined on the lunar surface within 300m of the deep base.

[0018] Furthermore, in step 4, if the deep lava cave is not connected to the lunar surface, a thermal rock-breaking lunar rover is first used to perform thermal exfoliation drilling by spraying high-temperature flames to form a lowering channel on the lunar surface that is connected to the deep lava cave.

[0019] Furthermore, in step five, the depth of the topological interlocking groove does not exceed 2 / 3 of the height of the topological interlocking structure.

[0020] Furthermore, in step six, the walls and top of the lunar surface base are both composed of a multi-layer interlayer structure. The multi-layer interlayer structure includes the same topological interlocking structure on both sides and an intermediate layer. The intermediate layer is a lunar soil filling layer with uniform thickness, which can increase the service life of the lunar surface base. The thickness of the topological interlocking structure gradually decreases from the inside to the outside, which takes into account both the stability of the unbonded lunar surface base and the long-term maintenance ability of the internal space temperature.

[0021] Furthermore, the water ice electrolysis lunar rover includes a water ice storage tank, an electrolysis chamber, an oxygen storage tank, a hydrogen storage tank, a first solar panel and a control device installed on the lunar rover mobile platform.

[0023] Considering the abundant water ice resources at the lunar South Pole and the current progress in lunar regolith water production technology, the inventors of this invention, relying on the thermal cracking mechanism of rocks, have proposed an in-situ, non-cemented, integrated construction method for the lunar surface and deep lunar base. Compared with existing technologies, this method has the following advantages:

[0024] 1. The present invention uses a water-ice electrolysis lunar rover, a thermal rock-breaking lunar rover, and a hoisting-and-transporting lunar rover to cooperate with each other. A deep lava cave on the moon is selected as a deep base, and the location of the lunar surface base is selected on the surrounding lunar surface. The hoisting-and-transporting lunar rover is then used to transport the water-ice electrolysis lunar rover and the thermal rock-breaking lunar rover to their respective locations. The water-ice electrolysis lunar rover continuously converts the water ice resources on the moon into hydrogen and oxygen to provide energy for thermal rock-breaking. The thermal rock-breaking lunar rover generates high-temperature flames to spray and break rocks, and thermally exfoliates the lunar soil and rocks through the high-temperature flames. process and the accompanying tensile thermal cracking process; through the simultaneous construction of the lunar surface base and the deep base, the materials used in the construction process are all taken from the moon, and the lunar surface base is built by relying on topological interlocking structures, realizing the in-situ non-bonded integrated construction of the lunar surface and lunar deep bases, matching the actual energy supply of the moon, and comprehensively utilizing the environmental advantages of the lunar surface and the deep moon, taking into account the stability of the lunar base and the comfort of space temperature, which can meet the specific needs of manned space missions and unmanned autonomous operations, and greatly increasing the functional coverage of a lunar base construction.

DETAILED DESCRIPTION

[0032] The present invention will be further described below.

[0033] like Figure 1 As shown, the present invention includes the following steps:

[0034] Step 1: Map the spatial distribution of deep lava caves on the Moon and select a deep lava cave as a deep base. Determine the location of the lunar surface base within 300 meters of the deep base. Simultaneously, prepare for the launch of the lunar rover on Earth.

[0035] Step 2: Launching a lunar rover assembly for lunar base construction from Earth to the Moon. The rover assembly includes a water-ice electrolysis rover, a thermal rock-breaking rover, and a hoisting-and-transporting rover. The hoisting-and-transporting rover is used to transport the thermal rock-breaking rover to the desired location in the deep lava cave and to load and unload the water-ice electrolysis rover assembly.

[0036] Step 3: Start the water ice electrolysis lunar rover. After the electrolysis generates a stable flow of hydrogen and oxygen, the hydrogen and oxygen are transported to the thermal rock-breaking lunar rover. Then, the thermal rock-breaking lunar rover is started. A high-temperature flame is generated by the mixed combustion of hydrogen and oxygen near the entrance of a deep lava cave. The target area is subjected to thermal exfoliation directional deep drilling to form a fixing hole 37 for the hoisting-transporting lunar rover to carry out heavy lifting-assembly operations. The hoisting-transporting lunar rover is then controlled to move to the fixing hole 37 to complete the fixing of the hoisting-transporting lunar rover.

[0037] Step 4: Control one of the thermal rock-breaking lunar rovers to the lunar surface base to perform thermal rock-breaking on lunar rock 2. The hoisting-transporting lunar rover transports the other thermal rock-breaking lunar rover to the deep lava cave below the lunar surface base to perform thermal rock-breaking on lunar rock 3 in the deep base. If the deep lava cave is not connected to the lunar surface, the thermal rock-breaking lunar rover is first used to perform thermal exfoliation drilling by spraying high-temperature flames to form a lowering channel on the lunar surface that is connected to the deep lava cave.

[0038] Step 5: Synchronously start the two thermal rock-breaking lunar rovers in step 4 and control their operating status in real time, such as Figure 2 As shown, one of the thermal rock-breaking lunar rovers uses jet flames to thermally cut lunar rock on the lunar surface to form a topological interlocking structure 1 and a topological interlocking groove 4 on the wall of the lunar surface base. The depth of the topological interlocking groove 4 does not exceed 2 / 3 of the height of the topological interlocking structure 1. The other thermal rock-breaking lunar rover uses jet flames to directional drill and extend the deep lava cave space and shape the lava cave wall to form a deep base.

[0039] Step 6. After the lunar rock cutting operation is completed, a part of the topological interlocking structure 1 formed by thermal cutting on the lunar surface is used as the wall of the lunar surface base by hoisting-building the lunar rover, so that it cooperates with the topological interlocking groove 4. After the thermal rock-breaking lunar rover in the deep lava cave space completes the directional extension construction of the connecting channel 9 between the deep base and the lunar surface base, the thermal rock-breaking lunar rover is lifted to the lunar surface by hoisting-building the lunar rover, and the other part of the topological interlocking structure 1 is hoisted and fixed to the upper part of the lunar surface base wall to form the top of the lunar surface base. Both the lunar surface base wall and the lunar surface base top are composed of a multi-layer interlayer structure, which includes the same topological interlocking structure 1 on both sides and an intermediate layer. The intermediate layer is a lunar soil filling layer with uniform thickness, which can increase the service life of the lunar surface base. In addition, the thickness of the topological interlocking structure 1 gradually decreases from the inside to the outside, which takes into account the stability of the uncemented lunar surface base and the long-term maintenance ability of the internal space temperature.

[0040] Step 7: Use the hoisting-building lunar rover to move a part of the topological interlocking structure 1 to the cave entrance of the deep base to form the topological interlocking deep base covering interlayer 5 to cover it. After completion, all lunar rover operations are stopped, completing the integrated construction process of the lunar surface base and the deep base.
