Description

Technical Field

[0001] The present invention relates to a lunar lava tube building structure system and a construction method, and in particular to a lunar lava tube building structure system and a construction method based on assembled modules, belonging to the technical field of lunar building engineering. Background Art

[0002] my country's lunar exploration project is planned to be divided into three stages: "unmanned lunar exploration", "manned lunar landing" and "establishing a lunar scientific research station" ("exploration, landing and residence"). At present, the three-phase mission of "orbiting, landing and returning" in the "unmanned lunar exploration" stage has been completed, and in 2021, China will jointly release the "International Lunar Scientific Research Station Roadmap" with Russia, and plans to complete the basic type of the unmanned scientific research station through 8 missions before 2035. Lunar construction engineering is an important infrastructure for lunar exploration and development, and an important symbol of my country's strategy to become a space power. Its main function is to provide shelter for lunar exploration equipment and a stable living environment for astronauts, and to meet the functional requirements of short-term manned operation and long-term automatic operation. Since the moon has no atmosphere to protect it, its surface has the characteristics of large temperature difference, high vacuum, strong radiation, long day and night, and is susceptible to direct impact from space meteorites and microparticles. Therefore, the construction of unmanned exploration equipment and manned cabins needs to consider protective structures to ensure the smooth operation of equipment and the safe residence of personnel. Against this background, it is of great significance to carry out research on lunar construction engineering technology in a timely manner.

[0003] Lava tubes are natural shelters on the moon that can protect lunar buildings from direct impacts of space meteorites and particles, making them an excellent location for lunar buildings. However, due to the high cost of transportation between the earth and the moon, as well as the complex lunar surface environment such as large temperature differences and strong radiation, lunar lava tube building structures need to have as little transportation mass and volume as possible, while being able to meet the requirements of rapid construction. Modular building assembly technology makes it possible to adapt to this special transportation and construction requirements.

However, during the prefabrication and assembly process, large-scale lifting machinery is required, and after prefabrication, the steel structure is large in size and has high transportation costs.

[0053] The present invention solves the problems of high difficulty, slow speed and high cost in constructing the lunar building structure system under the conditions of large temperature difference, strong radiation and micrometeoroid attack on the moon. Based on the environmental conditions of the lunar lava tube, a lunar lava tube building structure system based on assembled modules is provided.

[0054] The assembled module in the present invention adopts a multi-layer composite material panel, which has the functions of heat preservation and radiation protection on the basis of being lightweight and assemblable, and can effectively cope with the adverse environment of strong radiation and large temperature difference on the lunar surface. The module scale adopted and the designed connection mode between modules fully consider the use needs and activity characteristics of people in the microgravity environment of the moon. The patents of CN113338674B (Moon pit type manned lunar building structure and construction method based on the future lunar base) and CN114687451A (Moon surface type manned lunar building structure and construction method based on the future lunar base) are proposed based on the lunar pit and lunar surface environment respectively, and adopt an expandable inflatable structure to increase the transportation efficiency, and at the same time adopt the surface covered with lunar soil to cope with the complex environment of large temperature difference, strong radiation and micrometeoroid impact on the lunar surface. The difference between the present invention and the present invention is that the present invention makes full use of the natural shelter conditions of the lunar lava tube, so that it can be quickly constructed without covering the surface lunar soil, reducing the difficulty of construction and improving the speed of construction. The modularization in the invention of CN216142511U (A hexagonal inflatable expandable building module for lunar construction) is applicable to the lunar surface, but it is limited to the horizontal expansion of the module and cannot be applied to more scenarios with vertical expansion requirements.

[0058] Specific implementation method 2: Combination Figures 1 to 7 To illustrate the present embodiment, the rod basic unit 10 of the present embodiment includes a plurality of six-way carbon fiber connectors 1, a plurality of carbon fiber rods 3 and a plurality of modular panels 6. The six-way carbon fiber connector 1 is provided with a carbon fiber rod plug-in interface 2. Four six-way carbon fiber connectors 1 are arranged in a rectangular array.

[0065] Specific implementation method five: Combination Figure 6To explain this embodiment, the modular panel 6 of this embodiment is provided with plug-in protrusions 8 on the four edges, and a modular panel cut corner 7 is processed at the top corner between two adjacent plug-in protrusions 8 .

[0069] In this way, the carbon fiber door panels 15 and double-glazed windows 16 with openings of different sizes vary in length and width within a range of 4m×4m to accommodate the combination of different functional spaces.

[0070] The other components and connection relationships are the same as any one of the specific implementation modes 1 to 5.

[0071] Specific implementation method seven: Combination Figure 12 to Figure 13 To illustrate this embodiment, the modular panel 17 without traffic function in this embodiment includes two carbon fiber layers 12, a filling embedded layer 13 and a carbon fiber panel frame 18. The filling embedded layer 13 is embedded in the carbon fiber panel frame 18, and the two carbon fiber layers 12 are installed on the left and right sides of the carbon fiber panel frame 18.

[0072] Such arrangement plays a role in partitioning and blocking the wall traffic. The other components and connection relationships are the same as any one of the specific implementation modes 1 to 6.

[0073] Specific implementation method eight: Combination Figures 10 to 13 To explain this embodiment, the filling and embedding layer 13 of this embodiment is formed by stacking a continuous alumina fiber layer, a polyimide film layer and an aluminum foil composite material layer.

[0074] In this way, the lunar lava tube building structure system based on the assembled module can have the performance of heat insulation and radiation protection, and the light weight and high strength material characteristics make it conducive to reducing the economic cost in the transportation between the earth and the moon. The other components and connection relationships are the same as any one of the specific implementation methods one to seven.

[0075] In this embodiment, there are two types of attached panels: a modular panel 11 with traffic function and a modular panel 17 without traffic function. The modular panel with traffic function is composed of a carbon fiber surface layer 12, a filling layer 13 composed of a Nextel layer (referring to continuous aluminum oxide fiber), a Kapton layer (referring to a polyimide film) and an aluminum foil composite material layer, a carbon fiber door panel frame 14, a carbon fiber door panel 15, and a double-layer glass window 16.

[0077] With such arrangement, the solar panel 19 can be disassembled according to the specific situation, and other functional components, such as the lunar plant cabin, astronomical observatory, etc., can be inserted through the six-way carbon fiber connector 1. By adding the solar panel 19, it is used to convert solar energy into electrical energy to provide energy for lunar buildings. The other components and connection relationships are the same as any one of the specific embodiments 1 to 8.

[0078] Specific implementation method ten: Combination Figures 1 to 18 The present embodiment is described. The method for constructing a lunar lava tube building structure system based on assembled modules in the present embodiment comprises the following steps:

[0079] Step 1: Modular unit components of prefabricated building structures;

[0080] Prefabricate six-way carbon fiber connectors 1, carbon fiber rods 3 and modular panels 6 on the ground, and the attached panels include modular panels 11 with traffic functions and modular panels 17 without traffic functions;

[0081] Step 2: Use the carrier to transport the modular unit components prefabricated on the ground to the moon and assemble them. The assembly steps are as follows:

[0082] Step 21: Assemble from bottom to top, assemble the connection layer first. The assembly steps of the connection layer are:

[0083] S211: assembling a plurality of rod systems, connecting two adjacent six-way carbon fiber connectors 1 via a carbon fiber rod 3;

[0084] S212: two adjacent bar systems are connected via a modular panel 6;

[0085] S213: repeating step S211 and step S213 until a rectangular bottom surface of the connection layer is assembled;

[0086] Step 22: Assemble the support layer;

[0087] The attached panels are slidably inserted on the carbon fiber rods 3 of the rod system on the connection layer to form a support layer supported by the panels, wherein the attached panels in the support layer are modular panels 11 with traffic functions and / or modular panels 17 without traffic functions;

[0088] Step 23: A connecting layer is installed on the upper part of the supporting layer, and a supporting layer is installed on the upper part of the connecting layer, and this process is repeated until a building wall is assembled;

[0089] Step 3: Install the solar panel 19 on the building wall of the lunar building module facing the lava tube entrance, thereby completing the construction of the lunar lava tube building structure system based on the assembled module.

[0090] In this implementation, the modular unit components prefabricated on Earth are transported to the moon by a carrier, and the modules with transportation functions are preferentially plugged in to form the building skeleton. After the basic transportation function streamline is determined, the modules without transportation functions are expanded horizontally and vertically according to the requirements of building use. This method is more flexible and easier to adjust functions later.

[0091] Combination Figures 1 to 18 The working principle of the present invention is described:

[0092] The lunar lava tube building structure system based on the assembled module of the present invention includes a six-way carbon fiber connector 1, a carbon fiber rod 3, a modular panel 6, a carbon fiber surface layer 12, a filling layer 13, a carbon fiber door panel frame 14, a carbon fiber panel frame 18, a solar panel panel 19, etc. The rod system is composed of a six-way carbon fiber connector 1 and a carbon fiber rod 3. The six-way carbon fiber connector has a carbon fiber rod plug-in interface 2 at the top, bottom, left, right, front and back, and the carbon fiber rod end 4 can be combined with the carbon fiber connector by plugging. The carbon fiber rod 3 has a modular panel plug-in notch 5 at the top, bottom, front and back, which can be combined with the plug-in protrusion 8 at the edge of the modular panel 6 by plugging. There is a modular panel cut corner 7 at the edge of the modular panel 6 to facilitate the intersection 9 of the carbon fiber rod, the connector and the modular panel. Eight six-way carbon fiber connectors 1, eight carbon fiber rods 3 and six modular panels 6 can form a rod basic unit module 10. The rod basic unit module 10 can be expanded horizontally and vertically to meet the space requirements of different shapes and sizes in various lunar mission scenarios.

[0093] 26 six-way carbon fiber connectors 1 and 48 carbon fiber rods 3 form a 4m×4m basic use unit module 20, which can expand the building area by horizontal and vertical expansion. There are two types of modular panels 6: modular panels with traffic function 11 and modular panels without traffic function 17. The modular panel with traffic function is composed of a carbon fiber surface layer 12, a filling layer 13 composed of a Nextel layer, a Kapton and an aluminum foil composite material layer, a carbon fiber door panel frame 14, a carbon fiber door panel 15, and a double-layer glass window 16. The modular panel without traffic function 17 is composed of a carbon fiber surface layer 12, a filling layer 13 composed of a Nextel layer, a Kapton and an aluminum foil composite material layer, and a carbon fiber panel frame 18. The two types of modular panels 6, the six-way carbon fiber connector 1, and the carbon fiber rods 3 together form an assembled 4m×4m basic use unit module 20. The surface of the unit module can be attached with a solar panel 19 to convert solar energy into electrical energy to provide energy for lunar buildings.

[0094] In the example of the present invention, 3×3 4m×4m basic use unit modules 20 are assembled into a "wall"-like whole, and the application scenario is the entrance of the lava tube. The natural shelter conditions of the lava tube can greatly reduce the probability of the lunar building module being hit by meteorites. At the same time, the shielding of the lava tube can resist particle radiation and reduce the large temperature difference to provide a constant temperature environment. On this basis, the present invention proposes a solution that the surface of the building module is not covered with a thick lunar soil layer. Relying on the site selection of the lava tube, the requirements of the building insulation layer and the radiation layer can be reduced to a certain extent, reducing energy consumption while expanding the possibility of more construction of lunar buildings. Under the microgravity conditions of the moon, the lunar lava tube building structure system based on the assembled module in the present invention provides the possibility of vertical construction in this environment. Lightweight, high-strength and modular carbon fiber connectors 1, rods 3 and panels 6 are conducive to low-cost manufacturing and transportation, and mature assembly technology is conducive to rapid construction in the complex environment of the moon. The filling embedded layer 13 supported by multi-layer composite materials provides sufficient protection for the lunar building in the lava tube to resist the complex lunar environment with large temperature differences and strong radiation. The combination of solar panel panels 19 and the vertical form design solves the crucial energy problem for lunar buildings and provides a guarantee for long-term and sustainable lunar exploration.
