[0032] This application is based on the discovery and understanding of the following facts and issues:

[0033] With the continuous advancement of space exploration technology, humanity's exploration of lunar resources has progressed from exploration to development and utilization. As a key pillar of deep space exploration, the construction of a lunar base is of great significance for promoting scientific discovery, technological development, and even future interstellar travel.

[0034] As a native lunar resource, lunar regolith not only reduces the need to transport materials from Earth but also significantly lowers construction costs. Using masonry made from lunar regolith for lunar base construction is an ideal option for lunar base construction.

[0035] The lunar soil masonry in related technologies requires high construction precision, lacks construction redundancy, and requires deep human participation in the construction process. Considering the complex and uncertain special environment of the lunar surface, it is difficult for humans to participate in the construction, and robots are needed to build the lunar soil masonry. However, due to structural limitations such as the robot's sensors, construction accuracy is often difficult to guarantee.

[0036] Some masonry structures used on Earth in the related technology achieve positioning between masonry by setting protrusions or grooves on the masonry, but they only play a positioning role to increase the stability between the masonry, and cannot guide the masonry to reach a predetermined relative position, nor can they achieve self-positioning of the masonry.

[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] The following describes a self-placed lunar soil masonry structure 1 suitable for a lunar base according to an embodiment of the present invention with reference to the accompanying drawings.

[0041] like Figures 1-6 As shown, a self-positioning lunar soil masonry structure 1 suitable for a lunar base according to an embodiment of the present invention includes a plurality of lunar soil masonry bodies 10, each lunar soil masonry body 10 is prepared from lunar soil, and each lunar soil masonry body 10 has six surfaces 12, at least two opposite surfaces 12 of the six surfaces 12 form a self-positioning guide surface 11, each self-positioning guide surface 11 is non-planar, and each self-positioning guide surface 11 is a centrally symmetrical structure, and the two opposite self-positioning guide surfaces 11 are mirror-symmetrical, and each self-positioning guide surface 11 is suitable for tightly fitting with the self-positioning guide surface 11 of other lunar soil masonry bodies 10. When the two self-positioning guide surfaces 11 are tightly fitted, the relative positions of the two soil masonry bodies 10 where the two self-positioning guide surfaces 11 are located are in a predetermined relative position, and the self-positioning guide surface 11 is constructed to be suitable for guiding the two soil masonry bodies 10 to move to the predetermined relative position.

[0042] Specifically, Figure 1 、 Figure 2 、 Figure 5 and Figure 6It is shown that two opposite surfaces 12 of the six surfaces 12 of the lunar soil masonry 10 form the self-positioning guide surfaces 11 , namely the upper surface and the lower surface of the lunar soil masonry 10 . Figure 3 and Figure 4 It is shown that four of the six surfaces 12 of the lunar soil masonry 10 form self-positioning guide surfaces 11. The lunar soil masonry 10 may also have six surfaces 12 each forming a self-positioning guide surface 11.

[0043] like Figure 4 As shown, the predetermined relative position may be a unique position. Figure 2 and Figure 6 As shown, there may be two predetermined relative positions.

[0044] It should be understood that the two self-positioning guide surfaces 11 fit tightly together, and may fit completely together (e.g. Figure 2 The four rows of lunar soil masonry 10 in the middle and lower parts can also be partially fitted, for example, half of the two self-positioning guide surfaces 11 fit together (such as Figure 2 top three rows).

[0045] The lunar soil masonry 10 can be hollow or solid.

[0046] During construction, the robot assembles multiple lunar soil masonry blocks 10 into a building. If the lunar soil masonry blocks 10 are misplaced or deviated during the assembly process, the lunar soil masonry blocks 10 can automatically move to the predetermined relative position under the action of external forces such as gravity and the guidance of the self-positioning guide surface 11, so that each lunar soil masonry block 10 can reach the predetermined design position.

[0047] According to the self-placed lunar soil masonry structure 1 suitable for a lunar base according to an embodiment of the present invention, by making each lunar soil masonry 10 prepared from lunar soil, it is possible to fully utilize the in-situ resources on the lunar surface, reduce the need to transport materials from the Earth, and lower construction costs.

[0048] Furthermore, by forming a self-positioning guide surface 11 on each lunar soil masonry 10, each self-positioning guide surface 11 is adapted to closely mate with the self-positioning guide surface 11 of another lunar soil masonry 10, so that when the two self-positioning guide surfaces 11 are closely aligned, the relative positions of the two lunar soil masonries 10 are at a predetermined relative position, and the self-positioning guide surfaces 11 are configured to guide the two lunar soil masonries 10 to move to the predetermined relative position. Compared to lunar soil masonries in related technologies, this system can automatically move to the predetermined relative position under the guidance of the self-positioning guide surfaces 11 and external forces such as gravity when misalignment or other deviations occur during the assembly process of the lunar soil masonry 10, thereby reducing the precision requirements of construction equipment such as robots and improving the ability to adapt to the complexity and uncontrollability of the lunar surface environment.

[0049] In addition, by making each self-positioning guide surface 11 non-planar, each self-positioning guide surface 11 has a centrally symmetrical structure, and the two opposite self-positioning guide surfaces 11 are mirror-symmetrical, so that each lunar soil masonry 10 can still achieve mutual cooperation between the self-positioning guide surfaces 11 after being flipped horizontally and upside down, reducing the position requirements for each lunar soil masonry 10, further facilitating assembly, and reducing construction difficulty.

[0050] Furthermore, after the assembly is completed, the close fit of the self-positioning guide surface 11 can also improve the stability between the lunar soil masonry 10 and improve the integrity and stability of the building.

[0051] Therefore, the self-positioning lunar soil masonry structure 1 suitable for the lunar base according to the embodiment of the present invention can realize the self-positioning of the lunar soil masonry, reduce the construction accuracy requirements, and has the advantages of low cost, strong adaptability, and good stability.

[0052] The following describes a self-placed lunar soil masonry structure 1 suitable for a lunar base according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0053] In some specific embodiments of the present invention, Figures 1-6 As shown, the self-placed lunar soil masonry structure 1 suitable for a lunar base according to an embodiment of the present invention includes a plurality of lunar soil masonry bodies 10 .

[0054] Advantageously, each lunar regolith masonry 10 is provided with an adsorption structure adapted to adhere to the adsorption structures of other lunar regolith masonries 10. Because gravity on the moon is approximately one-sixth that of Earth, the adsorption structures provide additional force when assembling lunar regolith masonry 10 in insufficient gravity or when assembling lunar regolith masonry 10 in a direction not characterized by gravity, ensuring a tight fit between the self-positioning guide surfaces 11 of the lunar regolith masonry 10.

[0055] Optionally, the adsorption structure is a magnetic material layer, an electrostatic adsorption material layer or a self-assembled monolayer film, so that the magnetic force, electrostatic adsorption force or chemical adsorption force can be used to provide additional force to promote the mutual adsorption between the lunar soil masonry 10.

[0056] More advantageously, a photosensitive identification material layer is provided on the surface of the lunar soil masonry 10. In this way, it is possible to judge whether the lunar soil masonry 10 is assembled in place by the location and area of the light-sensitive identification material layer. For example, Figure 2 In the bottom two rows of lunar soil masonry 10, if the self-positioning guide surfaces 11 are completely aligned, the corresponding photosensitive identification material layer on the self-positioning guide surfaces 11 should be completely blocked, and it can be determined whether the two lunar soil masonry 10 is properly assembled. This makes it easier for construction equipment to identify the assembly position of the lunar soil masonry 10.

[0057] Figure 3 and Figure 4The following shows a self-placed lunar soil masonry structure 1 suitable for a lunar base according to some examples of the present invention. Figure 3 and Figure 4 As shown, four of the six surfaces 12 of each lunar regolith masonry 10 form self-positioning guide surfaces 11. These four self-positioning guide surfaces 11 include two opposing first guide surfaces 111 and two opposing second guide surfaces 112. The first guide surfaces 111 are adapted to closely mate with the second guide surfaces 112 of other lunar regolith masonries 10. This allows for the utilization of more surfaces of the lunar regolith masonry 10, enabling more complex and flexible assembly methods. Furthermore, after assembly, constraints can be formed in multiple directions, further enhancing the stability and reliability of the self-positioning lunar regolith masonry structure 1 suitable for lunar bases.

[0058] Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The following shows a self-placed lunar soil masonry structure 1 suitable for a lunar base according to some examples of the present invention. Figure 2 and Figure 6 As shown, the self-positioning guide surfaces 11 are respectively formed on the upper surface and the lower surface of the lunar soil masonry 10 (the up and down directions are indicated by the arrows in the figure and are only for the convenience of description, not for the limitation of the actual setting direction). The predetermined relative positions include a first relative position and a second relative position. In the first relative position, the projections of the two lunar soil masonry 10 in the plane perpendicular to the up and down directions overlap. In the second relative position, the projections of the two lunar soil masonry 10 in the plane perpendicular to the up and down directions partially overlap. Specifically, as Figure 2 As shown, the relative positions of the top three rows of lunar soil masonry 10 are the second relative positions, and the relative positions of the bottom four rows of lunar soil masonry 10 are the first relative positions. Figure 6 As shown, the relative position between the top two rows of lunar soil masonry 10 is the first relative position, and the relative position between the bottom two rows of lunar soil masonry 10 is the second relative position. This allows the lunar soil masonry 10 to have a more flexible combination method to be suitable for different types of buildings.

[0059] In some embodiments, as Figure 1 and Figure 2 As shown, the self-positioning guide surface 11 is one or more of a mirror-symmetrical surface, a rotationally symmetrical surface, and a translationally symmetrical surface. In this way, the lunar soil masonry 10 can be guided by the curved surface.

[0060] In other embodiments, Figure 3-Figure 6As shown, the self-positioning guide surface 11 includes multiple sub-slopes 113. Adjacent sub-slopes 113 are inclined relative to each other, and the multiple sub-slopes 113 are inclined relative to other surfaces 12 of the lunar soil masonry 10 other than the self-positioning guide surface 11. In this way, the lunar soil masonry 10 can be guided by the inclined surfaces.

[0061] Specifically, the lunar soil masonry units 10 are connected via a connecting interface material. Specifically, the connecting interface material can be an adhesive, a cementitious material, or a lunar soil material. Adhesive materials include, but are not limited to, epoxy resin, polysulfide rubber, acrylic resin, polyester resin, polyvinylidene fluoride, polycarbonate, and polysulfone; cementitious materials include, but are not limited to, phosphate cement, sulfate cement, and geopolymer cementitious materials; and lunar soil materials include, but are not limited to, screened lunar soil particles, lunar soil resin composite materials, and lunar soil sintered materials. This improves the connection performance between the lunar soil masonry units 10.

[0062] More specifically, the lunar regolith masonry 10 is formed through one or more of 3D printing, sintering, casting, adhesive bonding, and lunar regolith bag filling. Specifically, the 3D printing methods can include lunar regolith concrete 3D printing, laser melting 3D printing, solar concentrating 3D printing, and microwave melting 3D printing. This facilitates the molding of the lunar regolith masonry 10 and facilitates its in-situ production.

[0063] Specifically, the lunar soil masonry 10 can be used to assemble

[0064] The following describes a construction method for a self-placed lunar soil masonry structure 1 suitable for a lunar base according to the above embodiment of the present invention, including the following steps:

[0065] In-situ collection of lunar soil;

[0066] preparing the collected lunar soil into a plurality of lunar soil masonry blocks;

[0067] Assemble multiple lunar soil masonry blocks into a building.

[0068] According to the construction method of the self-positioning lunar soil masonry structure 1 suitable for the lunar base according to the above embodiment of the present invention, the lunar soil masonry can achieve self-positioning, reduce the construction accuracy requirements, and has the advantages of low cost, strong adaptability, and good stability.
