DETAILED DESCRIPTION

[0043] The embodiments of the present application are described in detail below with reference to the accompanying drawings, wherein the same or similar components are denoted by the same or similar reference numerals throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are for the purpose of explanation only, and are not to be understood as limiting the present application.

[0044] The lunar soil bag structure continuous filling and solidifying equipment 1 for lunar construction according to an embodiment of the present application and its construction method are described below in conjunction with Figures 1 to 12 ​

[0045] The first aspect of this invention proposes a continuous filling and solidification device 1 for lunar soil bag structures used in lunar surface construction.

[0046] like Figures 1 to 12 As shown, a continuous filling and curing device 1 for lunar soil bag structures for lunar surface construction according to a first aspect embodiment of the present invention includes a lunar soil bag 101, a pretreatment module 102, a robotic arm 103, a continuous filling module 104, and a curing actuator module 105. The pretreatment module 102 is used to mix lunar soil with a curing agent and short fibers to obtain mixed lunar soil. The robotic arm 103 is movable on the lunar surface. The continuous filling module 104 includes a lunar soil feeding device 1041 and a continuous filling actuator 1042. The inlet end of the lunar soil feeding device 1041 is connected to the pretreatment module 102, and the outlet end of the lunar soil feeding device 1041 is used to extend into the lunar soil bag 101 from the bag opening. The continuous filling actuator 104... 2. Fixed to the outlet end of the lunar soil feeding device 1041; the continuous filling actuator 1042 is connected to the end of the mechanical wall and is used to clamp and connect with the lunar soil bag 101 while the outlet end of the lunar soil feeding device 1041 extends into the lunar soil bag 101 and can move relative to the lunar soil bag 101, so that while the lunar soil feeding device 1041 fills from the bottom of the lunar soil bag 101 to the opening of the lunar soil bag 101, it gradually spreads the part of the lunar soil bag 101 to be filled along the predetermined path of the end of the mechanical arm 103, so that the filled lunar soil bag 101 is located at the predetermined path position; the curing actuator module 105 is used to connect to the end of the mechanical arm 103 to cure the mixed lunar soil filled in the lunar soil bag 101.

[0047] Specifically, such as Figures 6 to 9 As shown, the lunar soil bag 101 is a high-performance fiber cloth flexible bag, which is long and narrow. The lunar soil bag 101 is prefabricated on Earth, folded and compressed and transported to the lunar surface so that it can be filled with lunar soil on the moon, making full use of the in-situ resources of lunar soil and flexibly constructing lunar base buildings and structures.

[0048] like Figure 2As shown, the pretreatment module 102 is used to mix the lunar soil with the curing agent and the short fibers to obtain the mixed lunar soil. It needs to be explained that the lunar soil is the natural soil on the surface of the moon or the engineering material processed by screening the natural soil on the surface of the moon. Since the lunar soil generally has the problem of insufficient tensile strength, the material is difficult to withstand the tensile stress generated by one atmospheric pressure inside the lunar building and the temperature change outside, which is easy to cause material cracking and endanger the structural safety; the short fibers added in the lunar soil can effectively improve the tensile performance of the lunar soil bag 101 component, avoid material cracking, and ensure the structural safety. The short fibers can use the high molecular fiber, carbon fiber transported from the earth, or the basalt fiber prepared in situ on the moon surface, further improving the utilization rate of in-situ resources, but are not limited to this. The role of the curing agent added in the lunar soil is to cure the lunar soil through chemical reaction or bonding, and the stress performance of the cured lunar soil component is greatly improved compared with the loose lunar soil filled in the lunar soil bag 101, the structural bearing capacity and stability are obviously enhanced, and the structural safety is improved. The curing agent can use the high molecular binder transported from the earth, which has the characteristics of strong wave absorption capacity, low melting point, easy to reach the molten state under the action of microwaves, can save energy and time, and reduce the energy demand and time cost of lunar construction. Through the pretreatment module 102, the lunar soil, the curing agent and the short fibers can be automatically mixed uniformly, with high automation degree and high work efficiency.

[0049] As shown in Figure 1 , the mechanical arm 103 can move on the lunar surface, including but not limited to up, down, left and right movement, and the extension unit is arranged on the mechanical arm 103, and tools can be connected on the extension unit, so that the mechanical arm 103 has multiple functions; the mechanical arm 103 can be remotely controlled, so as to replace the astronauts to work on the lunar surface, and the mechanical arm 103 has high automation degree and high work efficiency.

[0050] As shown in Figure 3 and Figure 4 , the inlet end of the lunar soil feeding device 1041 is connected with the pretreatment module 102, including but not limited to flange connection, and the outlet end of the lunar soil feeding device 1041 is used to extend into the lunar soil bag 101 from the bag opening of the lunar soil bag 101; the continuous filling executor 1042 is fixed on the outlet end of the lunar soil feeding device 1041. That is, the lunar soil feeding device 1041 is connected between the pretreatment module 102 and the lunar soil bag 101, and can automatically fill the mixed lunar soil in the pretreatment module 102 into the lunar soil bag 101, with high automation degree.

[0051] The continuous filling implementer 1042 is fixed at the outlet end of the moon soil loading device 1041, and is connected at the end of the mechanical arm 103, used for being inserted into the moon soil bag 101 at the outlet end of the moon soil loading device 1041, and being clamped and connected with the moon soil bag 101 and being movable relative to the moon soil bag 101, so that the moon soil loading device 1041 fills the moon soil bag 101 from the bottom to the mouth of the moon soil bag 101, and the moon soil bag 101 is gradually spread according to the predetermined path of the end of the mechanical arm 103, so that the filled moon soil bag 101 is located at the predetermined path position. That is, the continuous filling implementer 1042 can make the outlet end of the moon soil loading device 1041 inserted into the moon soil bag 101, and clamped and connected with the moon soil bag 101 and movable relative to the moon soil bag 101, and fill the mixed moon soil into the moon soil bag 101 according to the predetermined path of the end of the mechanical arm 103, so as to ensure that the filled moon soil bag 101 is located at the predetermined position, and the degree of automation is high, and the work efficiency is high.

[0052] As shown in Figure 5 The solidification implementer module 105 is used for being connected at the end of the mechanical arm 103, and is used for solidifying the mixed moon soil filled in the moon soil bag 101. It can be understood that the solidification implementer module 105 is connected at the end of the mechanical arm 103, and can follow the movement of the mechanical arm 103, and the degree of automation is high. The solidification implementer module 105 can heat the solidification agent in the mixed moon soil region by region, so as to solidify the mixed moon soil, and ensure the structural strength of the moon soil bag 101, and the moon soil bag 101 after solidification has a certain shielding effect on adverse environmental factors such as radiation, extreme temperature, moon dust and micro meteorite.

[0053] When the moon soil bag structure continuous filling and solidification equipment 1 for lunar construction in the first aspect of the embodiment of the application is used, the moon soil is pretreated by the pretreatment module 102, and the moon soil is mixed with the solidification agent and the short fiber to obtain the mixed moon soil. Then, the mixed moon soil is filled into the moon soil bag 101 by using the mechanical arm 103 and the continuous filling module 104. The end of the mechanical arm 103 moves according to the predetermined route, so that the moon soil bag 101 is gradually spread and filled with the mixed moon soil on the predetermined path, and finally a strip-shaped filled moon soil bag 101 is formed. The filled moon soil bag 101 is stacked layer by layer to form a stacking structure. Finally, the solidification implementer module 105 is used to be close to the stacking structure by using the mechanical arm 103, and the solidification of the moon soil is completed region by region, so as to realize the construction of the lunar base building and structure. The lunar building can be used as the working and living space of the astronauts staying on the lunar surface. The appearance of the lunar structure is usually a wall body or a slope body, and can be used as the peripheral protective structure of the launch platform, the sunshade wall and the dustproof wall.
