[0002] As a crucial component of the lunar exploration program, lunar surface construction plays a crucial role in deep space exploration and research. On the one hand, lunar surface construction provides a stable and safe environment for scientific research, resource development, and technological advancement. On the other hand, lunar surface construction serves as a springboard for space exploration, expanding human activity and having a profound impact on human survival and development.

[0003] Construction on the lunar surface requires consideration of the harsh lunar environment: low gravity, ultra-vacuum conditions, large temperature swings, strong radiation, moonquakes, and numerous meteorites. This unique environment leads to significant differences in construction concepts and mechanical principles compared to Earth. Therefore, designing a lunar base that is adaptable, easy to install, and meets the requirements for seismic and impact resistance is crucial for lunar construction. Summary of the Invention

DETAILED DESCRIPTION

[0100] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0101] The following description sets forth specific details to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art will be able to make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0102] Example 1

[0103] like Figure 1 and Figure 2 As shown, the self-locking lunar base of the present invention includes a shock-absorbing mechanism and a cabin mechanism. The shock-absorbing mechanism is located below the cabin mechanism and is connected to the cabin mechanism via a connecting mechanism. The cabin mechanism in this embodiment is cylindrical. In addition to supporting the lunar base, the shock-absorbing mechanism also provides shock absorption.

[0104] like Figure 2 As shown, the shock-absorbing mechanism includes a limit frame 1, which has a hollow cavity inside. In this embodiment, the limit frame 1 is a rectangular parallelepiped, and the rectangular cavity is provided therein. Preferably, the limit frame 1 is a cube, and the cavity inside it is also cube-shaped. Several shock-absorbing layers are arranged from top to bottom within the grooves within the limit frame 1.

[0105] In this embodiment, four shock-absorbing layers are provided from top to bottom in the limiting frame 1, namely the first shock-absorbing layer, the second shock-absorbing layer, the third shock-absorbing layer and the fourth shock-absorbing layer. The first shock-absorbing layer is composed of the first splicing plate, the second splicing plate, and the rolling balls located between the first splicing plate and the second splicing plate. The second shock-absorbing layer is composed of the second splicing plate, the third splicing plate, and the rolling balls located between the second splicing plate and the third splicing plate. The third shock-absorbing layer is composed of the third splicing plate, the fourth splicing plate, and the rolling balls located between the third splicing plate and the fourth splicing plate. The fourth shock-absorbing layer is composed of the fourth splicing plate, the limiting frame bottom plate, and the rolling balls located between the fourth splicing plate and the limiting frame bottom plate. In this embodiment, the first splicing plate, the second splicing plate, the third splicing plate and the fourth splicing plate are preferably square plates.

[0106] like Figure 19 As shown, the bottom surface of the fourth splicing plate 3 is provided with several fourth splicing plate bottom grooves 301. The angle between the fourth splicing plate bottom grooves and the side of the splicing plate is 45 degrees. A fourth ball rolling channel is formed between the fourth splicing plate bottom grooves and the bottom plate of the limiting frame 1. The angle between the fourth ball rolling channel and the side of the splicing plate is 45 degrees. The balls 2 are placed in the fourth ball rolling channel. The fourth ball rolling channel formed between the limiting frame 1 and the fourth splicing plate 3 achieves a shock absorption effect in two directions along the fourth ball rolling channel.

[0107] like Figure 18 As shown, the top surface of the fourth splicing plate 3 is evenly spaced with a plurality of fourth splicing plate top surface grooves 302, the angle between the fourth splicing plate top surface grooves 302 and the side of the limiting frame is 45 degrees, and the fourth splicing plate top surface grooves 302 and the fourth splicing plate bottom surface grooves 301 are vertically arranged. Figure 17 As shown, the bottom surface of the third splicing plate 4 is provided with several third splicing plate bottom grooves 401. The third splicing plate bottom grooves 401 are inclined in the same direction as the fourth splicing plate top grooves 302, and are located directly above the fourth splicing plate top grooves 302. The third splicing plate bottom grooves 401 and the fourth splicing plate top grooves 302 form several third rolling ball channels. The angle between the third rolling ball channels and the side of the splicing plate is 45 degrees, and the third rolling ball channels and the fourth rolling ball channels are perpendicular to each other. The balls are placed in the third rolling ball channels. The third rolling ball channels formed between the fourth splicing plate 3 and the third splicing plate 4 achieve a shock absorption effect in two directions along the third rolling ball channels.

[0108] like Figure 16 As shown, the top surface of the third splicing plate 4 is evenly spaced with a plurality of third splicing plate top surface grooves 402, and the third splicing plate top surface grooves 402 are arranged along the width direction of the limiting frame. Figure 15As shown, the bottom surface of the second splicing plate 5 is provided with several second splicing plate bottom grooves 501. These second splicing plate bottom grooves 501 are arranged along the width of the limit frame and are located directly above the third splicing plate top grooves 402. The second splicing plate bottom grooves 501 and the third splicing plate top grooves 402 form several second ball rolling channels. The second ball rolling channels are arranged along the width of the limit frame, and the balls 2 are placed in the second ball rolling channels. The second ball rolling channels formed between the third splicing plate 4 and the second splicing plate 5 achieve a shock absorption effect in both directions along the second ball rolling channels.

[0109] like Figure 14 As shown, the top surface of the second splicing plate 5 is evenly spaced with a plurality of second splicing plate top surface grooves 502, which are arranged along the length direction of the limiting frame, so the second splicing plate top surface grooves 502 and the second splicing plate bottom surface grooves 501 are perpendicular to each other. Figure 13 As shown, the bottom surface of the first splicing plate 6 is provided with several first splicing plate bottom surface grooves 601. The first splicing plate bottom surface grooves 601 are arranged along the length of the limit frame and are located directly above the second splicing plate top surface grooves 502. The first splicing plate bottom surface grooves 601 and the second splicing plate top surface grooves 502 form several first rolling ball channels. The first rolling ball channels are arranged along the length of the limit frame, and the first rolling ball channels are arranged perpendicular to the second rolling ball channels. Rolling ball 2 is placed in the first rolling ball channel. The first rolling ball channel formed between the first splicing plate 6 and the second splicing plate 5 achieves a shock absorption effect in two directions along the first rolling ball channel.

[0110] When a moonquake occurs, the vibration is first transmitted to the restraining frame, then through the various damping layers arranged from bottom to top, ultimately to the cylindrical cabin mechanism. During this vibration transmission process, the rolling of the balls within the ball channels evenly offsets the vibration energy in all directions, achieving effective shock absorption. The four damping layers in this embodiment achieve the eight-directional shock absorption effect of the shock absorption mechanism described herein, providing the lunar base with excellent shock absorption and enabling it to better adapt to the lunar environment.

[0111] The second splicing plate 5, the third splicing plate 4 and the fourth splicing plate 3 in this application are formed by splicing blocks. In this embodiment, the splicing blocks are square, and the splicing plates formed by splicing the splicing blocks are also preferably square plates. In this embodiment, the splicing structure of the second splicing plate 5 is described in detail.

[0112] like Figure 20As shown, the splicing block 14 is a small block with a square cross-section. The splicing block 14 has four sides of equal length. Two adjacent sides are provided with dovetail tenons 1401, and the other two adjacent sides are provided with dovetail grooves 1402. The dovetail tenons 1401 are inserted into the dovetail grooves 1402 of the adjacent splicing block, thereby connecting the two adjacent splicing blocks. Preferably, the dovetail tenons and dovetail grooves in this embodiment are both located in the middle of the splicing block sides.

[0113] In this embodiment, a socket 1403 is provided on the splicing block 14 at a position midway between one-quarter of the side length of the side where the dovetail joint is located. A latch 1404 disposed within the socket allows connection between adjacent upper and lower splicing panels. In this application, the location of the socket 1403 is not limited to this, as long as the location of the socket is consistent across all splicing blocks comprising the same splicing panel.

[0114] The splicing board in this application includes several upper and lower splicing layers, and the splicing layers are connected by pins. The splicing board in this embodiment is formed by connecting three upper and lower splicing layers. First, a first splicing layer is formed by splicing several splicing blocks. Then, a second splicing layer is formed by splicing several splicing blocks together. The second splicing layer is located above the first splicing layer, and the splicing blocks between the adjacent upper and lower splicing layers are arranged in opposite directions, and the jacks between the adjacent upper and lower splicing layers are arranged correspondingly: Figure 21 As shown, a dovetail tenon is provided on one side of the splicing blocks constituting the first splicing layer, while a dovetail groove is provided on the same side of the splicing blocks constituting the second splicing layer. Finally, a third splicing layer is formed by splicing several splicing plates together, and the third splicing layer is located above the second splicing layer. The splicing blocks constituting the third splicing layer are arranged opposite to the splicing blocks constituting the second splicing layer, so the splicing blocks constituting the third splicing layer are arranged in the same direction as the splicing blocks constituting the first splicing layer, and the splicing blocks constituting the third splicing layer are located directly above the splicing blocks constituting the first splicing layer, as shown in FIG. Figure 22 At the same time, grooves are provided on the top surfaces of the splicing blocks of the third splicing layer, and the grooves on two adjacent splicing blocks are interconnected, thereby forming grooves 502 on the top surface of the second splicing plate.

[0115] The jacks on the corresponding splicing blocks of the upper and lower splicing layers are connected, and the above-mentioned jacks are penetrated by a plug, and the connection between the upper and lower splicing layers is achieved by the plug. Figure 24 As shown, in order to form a complete second splicing plate.

[0116] The splicing structure of the third and fourth splicing plates 4 and 3 is identical to that of the second splicing plate 5. Unlike the second splicing plate, the grooves of the topmost splicing blocks of the third and fourth splicing plates are oriented differently from those of the second splicing plate. In the present application, a splicing plate can be formed by plugging together several identical splicing blocks and latches, significantly reducing the number of components that make up the splicing plate and facilitating standardized and modular design of the splicing plate components.

[0117] The cylindrical cabin mechanism in this embodiment includes a cylindrical cabin, an inflatable cabin 11, a front cabin door 9 and a rear cabin door 10. The front end of the cylindrical cabin is provided with a front cabin door 9, and the rear end of the cylindrical cabin 10 is provided with a rear cabin door 10. The cylindrical cabin, the front cabin door 9 and the rear cabin door 10 form a cylindrical cavity. The inflatable cabin 11 is fixedly arranged in the cavity, and the front end of the inflatable cabin 11 is connected to the front cabin door 9.

[0118] In this embodiment, the cylindrical cabin comprises two layers of cladding, inner and outer, which are formed by inserting a plurality of mortise and tenon bricks 12. The inner and outer cladding layers are fixedly connected by mortise and tenon joints. That is, the inner cladding 15 and the outer cladding 16 are respectively inserted by mortise and tenon bricks 12, and then the inner cladding 15 and the outer cladding 16 are connected by mortise and tenon joints, thereby forming a complete cylindrical cabin. Figure 6 shown.

[0119] The inner and outer claddings are connected in exactly the same manner. This embodiment specifically describes the inner cladding's connection structure. The inner cladding comprises an array of mortise and tenon joint rings arranged axially along the cabin. These rings are closed circular rings, with adjacent rings securely connected by joints. In this embodiment, each set of mortise and tenon joint rings is formed by joining ten mortise and tenon bricks 12 located on the same circumference. The central angle of each mortise and tenon brick is 36°.

[0120] like Figure 7 and Figure 8As shown, the mortise and tenon brick 12 includes a curved brick body 1201 having four curved side surfaces and two flat surfaces at its ends. The curved side surfaces of the mortise and tenon brick include a front curved surface 1202, a rear curved surface 1203, an inner curved surface 1204, and an outer curved surface 1205. The front curved surface 1202 faces the front hatch, while the rear curved surface 1203 faces the rear hatch. The front curved surface 1202 is provided with a curved tenon groove 1207, and the corresponding rear curved surface 1203 is provided with a curved tenon 1206. The curved tenon 1206 can be fixedly inserted into the curved tenon groove 1207 of the adjacent mortise and tenon brick. The curved mortise and tenon groove 1207 on the front curved surface 1202 realizes the mortise and tenon connection between the mortise and tenon brick block and the mortise and tenon brick block in front of it, and the fixed connection between the mortise and tenon brick block and the front hatch in front of it; the curved tenon head 1206 on the rear curved surface 1203 realizes the mortise and tenon connection between the mortise and tenon brick block and the mortise and tenon brick block behind it, and the fixed connection between the mortise and tenon brick block and the rear hatch behind it.

[0121] In this embodiment, the inner curved surface 1204 is the side facing the inside of the cylindrical cabin, and the outer curved surface 1205 is the side facing the outside of the cylindrical cabin. The inner curved surface 1204 is provided with a curved tenon groove 1207, and the corresponding outer curved surface 1205 is provided with a curved tenon 1206. The curved tenon 1206 can be inserted and fixed in the curved tenon groove 1207 of the adjacent tenon-and-mortise brick. The curved tenon insertion block 1206 on the outer curved surface 1205 realizes the mortise and tenon connection between the tenon-and-mortise brick and the tenon-and-mortise brick outside it; the curved tenon groove 1207 on the inner curved surface 1204 realizes the mortise and tenon connection between the tenon-and-mortise brick and the tenon-and-mortise brick inside it.

[0122] A tenon 1208 is located at the center of one end plane of a mortise-and-tenon block, and a groove 1209 is located at the center of the other end plane of the corresponding mortise-and-tenon block. The tenon 1208 can be securely inserted into the groove 1209 of an adjacent mortise-and-tenon block. The groove 1209 and the tenon 1208 between the two adjacent planes form a mortise-and-tenon connection between two adjacent mortise-and-tenon blocks located on the same circumferential surface.

[0123] The structure of the mortise and tenon bricks in this application is symmetrical, realizing the standardized and modular structural design of the mortise and tenon bricks. In actual use, there is no need to identify their direction, and they can be plugged and fixed in the same direction, making the plug-in and fixation process of the entire cylindrical cabin very convenient, facilitating the construction of the cylindrical cabin on the moon.

[0124] In this application, the outer and inner covering layers are connected in the same manner, the only difference being that the radius of the mortise and tenon bricks forming the outer covering layer is larger than that of the mortise and tenon bricks forming the inner covering layer. The mortise and tenon bricks of the outer and inner covering layers are connected in a mortise and tenon manner.

[0125] like Figure 9 As shown, two insertion protrusions 901 are provided on the side of the front door 9 facing the cylindrical cabin body. The two insertion protrusions 901 are fixedly inserted into the arcuate tenon grooves 1207 on the mortise and tenon bricks 12 of the inner and outer cladding layers, respectively. That is, the insertion protrusions 901 and the arcuate tenon grooves 1207 achieve a fixed connection between the cylindrical cabin body and the front door 9. The side of the front door 9 away from the cylindrical cabin body is flat. A center hole is provided in the center of the front door 9, and the connection between the front door 9 and the cylindrical cabin body is achieved through this circular hole. In this embodiment, to facilitate the manufacture and installation of the front door 9, the front door 9 is composed of two semicircular rings.

[0126] like Figure 10 As shown, the rear hatch 10 has two insertion grooves 1001 on the side facing the cylindrical cabin. The curved tenons 1206 of the inner and outer cladding bricks 12 are respectively fixedly inserted into the two insertion grooves 1001. The insertion grooves 1001 and the curved tenons 1206 establish a fixed connection between the cylindrical cabin and the rear hatch 10. The side of the rear hatch 10 facing away from the cylindrical cabin is flat. In this embodiment, to facilitate the manufacture and installation of the rear hatch 10, the rear hatch 10 is composed of two semicircular plates.

[0127] In this application, the cylindrical cabin is not limited to the two inner and outer cladding layers described in this embodiment and may include multiple cladding layers. The shapes of the front and rear doors are also not limited to those described above. The placement and specific number of plug-in projections or grooves on the front and rear doors will depend on the specific structure of the cylindrical cabin to which they are connected. Specifically, if the side of the cylindrical cabin facing the front door is provided with an arcuate tenon groove, a corresponding number of plug-in projections must be provided on the corresponding surface of the front door. Similarly, if the side of the cylindrical cabin facing the rear door is provided with an arcuate tenon groove, a corresponding number of plug-in grooves must be provided on the corresponding surface of the rear door.

[0128] like Figure 11As shown, the inflatable cabin 11 in this embodiment is cylindrical, and the inflatable cabin 11 is arranged in a cylindrical cavity surrounded by the cylindrical cabin body, the front cabin door and the rear cabin door. After the inflatable cabin 11 is inflated, it can fill the entire cylindrical cabin body. A limit plate 1101 is provided at the front end of the inflatable cabin 11, and the limit plate 1101 is fixedly connected to the inflatable cabin through a fixed shaft 1102. The fixed shaft 1102 is arranged in the center hole 902 of the front cabin door, and the radius of the fixed shaft 1102 is smaller than the radius of the center hole 902; the radius of the limit plate 1101 is larger than the radius of the center hole 902. Therefore, through the above structure, the connection between the inflatable cabin 11 and the front cabin door 9 is realized. After the inflatable cabin 11 is filled with gas, the staff can complete their work on the moon in the inflatable cabin 11.

[0129] The shock absorbing mechanism and the cylindrical cabin mechanism are fixedly connected by a connecting mechanism. The connecting mechanism includes a base support 8 and top paving bricks 7. Figure 12 As shown, the top surface of the first splicing plate 6 is provided with a concave-convex mortise and tenon structure.

[0130] The bottom ends of the cylindrical hull are connected to base supports 8. The base supports 8 have curved surfaces facing the sides of the cylindrical hull, which are fixedly connected to the cylindrical hull via plug-in fastening. The bottom surface of the base supports 8 facing the first splicing plate is flat, which is fixedly connected to the first splicing plate via plug-in fastening.

[0131] In this embodiment, two foundation supports 8 are provided at the bottom of the cylindrical cabin, symmetrically arranged on the bottom surface of the cylindrical cabin. Each foundation support 8 comprises two symmetrically arranged foundation support blocks 803. When the two foundation support blocks 803 are joined, they form a foundation support with a semicircular upper surface. Several arcuate slots 801 are spaced apart on the curved surface of the foundation support blocks 803 facing the cylindrical cabin. The arcuate tenons 1206 on the mortise and tenon bricks are fixedly inserted into the arcuate slots 801, thereby achieving a fixed connection between the foundation support 8 and the cylindrical cabin.

[0132] The bottom surface of the basic support block 803 is a mortise and tenon structure corresponding to the upper surface of the first splicing plate, and the basic support block 8 is fixedly connected to the first splicing plate 6 through the mortise and tenon connection.

[0133] The top surface of the first splicing panel 6 is paved with top paving bricks 7, and the bottom surface of the top skin bricks 7 is connected to the top surface of the first splicing panel 6 via mortise and tenon joints. After the top paving bricks 7 are laid, gaps are reserved on the top surface of the first splicing panel 6 for connection with the foundation support 8. The foundation support 8 is fixedly connected to the first splicing panel 6 through these gaps.

[0134] In this embodiment, the first splicing plate 6 is formed by splicing a plurality of first splicing blocks, and the top paving bricks 7 are formed by splicing a plurality of paving splicing blocks. Because the splicing seams of the first splicing plates and the splicing seams of the top paving bricks 7 are staggered, when the first splicing plates 6 and the top paving bricks 7 are connected by mortise and tenon joints, the first splicing blocks are spliced ​​and fixed together, the paving splicing blocks are spliced ​​and fixed together, and the first splicing plates 6 and the top paving bricks 7 are fixedly connected.

[0135] This application also includes the installation method of the above-mentioned self-locking lunar base, such as Figure 25(a) to Figure 25(r) As shown, the installation method includes the following installation steps.

[0136] The first step is to excavate a foundation pit on the lunar surface. After leveling the pit surface, a limiting frame 1 is placed in the pit, as shown in Figure 25(a).

[0146] In the eleventh step, the bottom surface of the base support 8 is connected to the first splicing plate 6 by mortise and tenon joints, as shown in FIG25( k ).

[0147] In the twelfth step, the arc-shaped tenon on the outer surface of the mortise and tenon brick 12 is connected to the arc-shaped slot on the arc surface of the base support 8 by mortise and tenon, as shown in Figure 25 (l).

[0148] In the thirteenth step, the mortise and tenon bricks 12 are connected one by one from the basic supports on both sides to the inside to complete the lower assembly of the outer mortise and tenon bricks, as shown in Figure 25 (m).

[0149] Step 14: Connect the inner layer of mortise and tenon bricks with the inner side mortise and tenon bricks of the outer layer. First, install the mortise and tenon bricks at the lower part of the inner layer. Connect the inner layer of mortise and tenon bricks one by one along the axial direction. At the same time, connect the inner layer of mortise and tenon bricks with the corresponding outer layer of mortise and tenon bricks to complete the lower assembly of the inner layer of mortise and tenon bricks, as shown in Figure 25 (n).

[0150] Step 15. After the lower assembly of the inner mortise and tenon bricks is completed, the inner mortise and tenon bricks are mortised from bottom to top to complete the upper assembly of the inner mortise and tenon bricks, as shown in FIG25(o).
