[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The first embodiment

[0021] Please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional assembly schematic diagram of the lunar base environment simulation device provided by the first embodiment of the present invention. Figure 2 is Figure 1 A three-dimensional assembly schematic diagram of the lunar base environment simulation device with some structures removed shown.

[0022] A lunar environment simulation device 100 includes a lunar ground simulation system 101 and a lunar rock simulation system 103 connected to each other. The lunar ground simulation system 101 is used to simulate the lunar ground environment. The lunar rock simulation system 103 is used to simulate the lunar rock environment to simulate the lunar underground environment.

[0023] The lunar environment simulation device 100 provided in this embodiment takes into account the complex environment of the lunar surface and underground, improves the accuracy of simulating the lunar environment on Earth, and thus improves the test accuracy. In addition, since the test object does not need to switch between different environments, time is saved and the test efficiency is improved.

[0024] Specifically, the lunar ground simulation system 101 includes a simulation cabin 10, a lunar soil simulation system 20 and a vacuum simulation system 30. The lunar soil simulation system 20 and the vacuum simulation system 30 are both connected to the simulation cabin 10. The lunar soil simulation system 20 is used to provide the simulation cabin 10 with a lunar soil simulation environment, and the vacuum simulation system 30 is used to evacuate the simulation cabin 10 to simulate the vacuum environment of the moon.

[0025] The lunar soil simulation system 20 includes a lunar soil simulant 21. The simulation cabin 10 is fixedly arranged on the lunar soil simulant 21, and the lunar rock simulation system 103 is arranged on the side of the lunar soil simulant 21 away from the simulation cabin 10. The test object (not shown) can walk on the lunar soil simulant 21 for testing. It can be understood that the test object can be other equipment or devices such as a corer system, a spacecraft, etc., which are not limited here.

[0026] The lunar soil simulation system 20 also includes a dust sprinkler 22, a charged particle accelerator 23 and an ultraviolet generating device 25 fixed on the simulation cabin 10. The dust sprinkler 22 is fixed to the simulation cabin 10 and is used to provide lunar dust simulants into the simulation cabin 10 to simulate the dust environment on the lunar surface. The charged particle accelerator 23 is used to generate a proton beam to make the lunar dust simulants electrostatic. When the test object moves on the lunar soil simulant 21, the surface of the test object can adhere to the raised simulated lunar dust. The ultraviolet generating device 23 is used to emit ultraviolet rays into the simulation cabin 10 to simulate the photoelectric effect of lunar dust under the action of ultraviolet rays. Since the lunar ground simulation system 101 is provided with a charged particle accelerator 23, an ultraviolet generating device 25 and a dust sprinkler 22, the dust environment on the moon is simulated, thereby improving the simulation accuracy of the lunar ground environment. It can be understood that the lunar soil simulation system 20 can omit the dust sprinkler 22, the charged particle accelerator 23 and the ultraviolet generating device 25.

[0027] In this embodiment, the preparation of the lunar soil simulant 21 can be referred to the following description: The lunar soil simulant 21 is obtained by crushing, size grading, particle size grading, mixing, and outgassing pretreatment of soil with physical and chemical properties similar to those of lunar soil. The particle size of lunar soil is very small, and particles with a size of less than 1 mm account for more than 95% of the total mass.

[0028] The mineral clasts (defined here as particles containing more than 80% of a certain mineral, mainly olivine, plagioclase, pyroxene, ilmenite, spinel, etc.), primary crystalline rock clasts (basalt, anorthosite, peridotite, norite, etc.), breccia clasts, various glasses (molten rock, microbreccia, impact glass, yellow or black igneous clastic glass), agglomerate rock, meteorite fragments, etc. provided in this embodiment act as the simulant of lunar dust and soil after pretreatment.

[0029] The lunar rock simulation system 103 includes a heat-insulating container 1031 and a lunar rock simulant 1033 accommodated in the heat-insulating container 1031. The lunar rock simulant 1033 and the lunar soil simulant 21 are stacked. The lunar rock simulant 1033 is disposed on the side of the lunar soil simulant 21 away from the simulation chamber 10.

[0030] In this embodiment, the preparation of the lunar rock simulant 1033 can be referred to the following description: According to the lunar topographic features, lunar rocks are generally divided into mare basalt and highland anorthosite. Therefore, in the simulation chamber 10, basalt blocks and basalt materials with different particle sizes can be mixed for preparation, and the lunar rock simulant 1033 can be heated in different regions according to the temperature distribution characteristics at different depths on the lunar surface to simulate the most realistic lunar surface environment, that is, the lunar rock simulant 1033 includes at least two regions with different temperatures.

[0031] More specifically, the simulation chamber 10 includes a first chamber 11 and a second chamber 13 communicating with the first chamber 11. A hatch 111 is provided on the first chamber 11. The hatch 111 is used to open or close the first chamber 11. An observation window 112 is provided on the first chamber 11. The observation window 112 is used for the experimenter to observe and record the experimental conditions inside the first chamber 11. Among them, the dust sprinkler 22, the charged particle accelerator 23, and the ultraviolet generating device 25 are all provided on the second chamber 11.

[0032] It can be understood that the number of hatches 111 is not limited. For example, the hatch 111 can be one or more than two. It can be understood that the number of observation windows 112 is not limited. For example, the observation window 112 can be one or more than two.

The vacuum simulation system 30 includes a gas storage tank 31, a vacuum pump 32, a Roots pump 33, an oil diffusion pump 34, and a pipeline 35. The gas storage tank 31, the vacuum pump 32, the Roots pump 33, and the oil diffusion pump 34 are connected in sequence through the pipeline 35. The vacuum pump 32, the Roots pump 33, and the oil diffusion pump 35 are used to evacuate the simulation chamber 10 to simulate the lunar vacuum environment. It can be understood that the structure of the vacuum simulation system 30 is not limited as long as it can meet the requirement of evacuating the simulation chamber 10.

[0034] Further, the vacuum simulation system 30 further includes a mounting bracket 37, and the vacuum pump 32 and the Roots pump 33 are arranged on the mounting bracket 37.

[0035] There is almost no atmosphere and atmospheric activity on the lunar surface, and the temperature difference between day and night is very large. The daytime temperature is 403 - 423K, and the nighttime temperature is 93 - 113K. As the temperature on the lunar surface changes, the lunar surface pressure varies within the range of 10 -9 ~10 -13 Pa. There are meteorite impact craters at the lunar poles that are not irradiated by the sun all year round, with a temperature of 40 - 50K, and the water ice content is (66 - 200)×10 8 t. Please refer to Figure 1 and Figure 2 again. In this embodiment, the lunar ground simulation system 101 further includes a temperature regulation system 40 arranged in the simulation chamber 10, which is used to regulate the temperature in the simulation chamber 10 to simulate the extreme temperature environment on the moon. It can be understood that the temperature in the simulation chamber 10 is regulated by the temperature regulation system 40 at different time points.

[0036] Further, the inner wall of the first cabin 11 is coated with a heat sink 15, which is used to simulate the extremely cold and extremely dark environment of the lunar environment. The temperature regulation system 40 includes a helium gas temperature regulation system 41 and a liquid nitrogen refrigeration system 43 connected in series with the helium gas temperature regulation system 41 to realize temperature regulation of the heat sink 15. In this embodiment, the liquid nitrogen provided by the liquid nitrogen refrigeration system 43 is further cooled to 70K by the helium gas provided by the helium gas temperature regulation system 41; within the temperature range of 150 - 400K, the helium gas temperature regulation system 41 is used to control the temperature of the heat sink 15.

[0038] The liquid nitrogen refrigeration system 43 includes a nitrogen generator 431, a liquid nitrogen storage device 433, a compressor 435 and an air pipe 437. The compressor 435 is connected to the nitrogen generator 431 through the air pipe 437, and the nitrogen generator 431 is connected to the liquid nitrogen storage device 433 through the air pipe 437. The nitrogen generator 431 is used to produce nitrogen, and the compressor 435 is used to compress the produced nitrogen and store it in the liquid nitrogen storage device 433.

[0039] The temperature adjustment system 40 further includes an array of lamps 45 (such as Figure 2 shown), and the array of lamps 45 is housed in the simulation chamber 10 and is used to simulate the collimated light of the sun. Since the array of lamps 45 is used to simulate the solar spectrum, heat flux, and altitude angle, the simulation accuracy of the lunar-based environmental device 100 for the lunar environment is further improved. In this embodiment, the array of lamps 45 is an infrared lamp array, which can also be used as a partial heat source to adjust the temperature in the simulation chamber 10.

[0040] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 a cross-sectional view of the lunar-based environmental simulation device shown, Figure 5 and is a partial enlarged schematic view of the microgravity simulation system of an embodiment of the lunar-based environmental simulation device of the present invention.

[0041] The lunar ground simulation system 101 further includes a microgravity simulation system 50. The microgravity simulation system 50 is located in the first cabin 11 of the simulation chamber 10 to provide a pulling force to the test object in the simulation chamber 10, offset a part of the earth gravity received by the test object, and realize the simulation of the microgravity environment where the test object is located on the moon.

[0042] The microgravity simulation system 50 includes a support frame 51 and a mobile suspension device 53. The support frame 51 is fixed to the inner wall of the first cabin 11 and is used to support the mobile suspension device 53. The mobile suspension device 53 is movably arranged on the support frame 51.

The mobile platform 513 is slidably connected to the second guide rail 512. The connecting member 514 is suspended on the mobile platform 513 and is used to connect with the test object to provide a pulling force to the test object. One end of the connecting member 514 facing away from the mobile platform 513 is provided with a hook (not shown in the figure). During use, the traction point of the hook is located at the centroid position of the test object. The first driving member 515 is fixed on the first guide rail 511 and is used to drive the second guide rail 512 to move along the first guide rail 511. The second driving member 515 is fixed on the second guide rail 512 and is used to drive the mobile platform 513 to move along the second guide rail 512. The first driving member 515 and the second driving member 516 can adjust the position of the mobile platform 513 according to the movement track of the test object, so as not to affect the movement of the test object.

[0043] The microgravity simulation system 50 utilizes the principle of gravity compensation on the test object. Through the combination of structures such as guide rails and suspensions and adding counterweights, it satisfies the completely unconstrained six degrees of freedom and truly simulates the operation on the lunar surface. It can be understood that the microgravity simulation system 50 is not limited to the structure shown in this embodiment. The microgravity simulation system 50 can also be other structures or devices. For example, the microgravity simulation system 50 can adopt the method of balloon suspension.

In this embodiment, the ray device 61 is used to emit x and y rays. It can be understood that the ray device 61 is not limited to emitting x and y rays. For example, the ray device 61 can only emit one of x and y rays or other types of rays. The radioactive radiation member 63 is located inside the first cabin 11 of the simulation cabin 10. In this embodiment, the radioactive radiation member 63 is a radioactive radiation ring that is generally annular. The number of the radioactive radiation members 63 is two. The two radioactive radiation members 63 are arranged at intervals. The radioactive radiation member 63 is separated from the heat sink 15 by an adiabatic layer (not shown in the figure). The array lamp 45 is located between the two radioactive radiation members 63.

[0045] It can be understood that the number of radiation-emitting members 63 can be one, three, or more; in order to make the radiation uniform at various positions in the simulation cabin 10, improvements can be made by increasing the arrangement density and size of the radiation-emitting members 63. In one embodiment, the lunar base environment simulation device 100 further includes a detector (not shown in the figure), and the detector is used to detect the radiation intensity in the first cabin 11 of the simulation cabin 10, and the controller adjusts the radiation intensity of the radiation-emitting members 63 according to the radiation intensity detected by the detector.

The first driving member 1108 and the second driving member 1109 can adjust the position of the mobile platform 513 according to the movement track of the test object, so as not to affect the movement of the test object.

[0068] The microgravity simulation system 110 utilizes the principle of gravity compensation on the test object. Through the combination of structures such as guide rails and suspensions and adding counterweights, it satisfies the completely unconstrained six degrees of freedom and truly simulates the operation on the lunar surface. It can be understood that the microgravity simulation system 110 is not limited to the structure shown in this embodiment. The microgravity simulation system 110 can also be other structures or devices. For example, the microgravity simulation system 110 can also be in the form of balloon suspension.

[0069] The lunar-based environment simulation device 200 further includes a ray device 121. The ray device 121 is installed in the second cabin 72 of the simulation cabin 70 and is used to emit rays into the simulation cabin 70 to simulate cosmic rays. In this embodiment, the ray device 121 is used to emit x and y rays. It can be understood that the ray device 121 is not limited to emitting x and y rays. For example, the ray device 121 can emit only one of x and y rays or other types of rays.

[0070] The lunar-based environment simulation device 200 provided by the second embodiment of the present invention improves the authenticity of the lunar environment simulation by simulating extreme lunar surface environments such as vacuum, microgravity, extreme temperature differences, high cosmic radiation, and microdust, and also considering the simulation of the underground environment of lunar rocks, thereby improving the accuracy of tests on test objects such as walking, detecting, and coring in the lunar-based environment simulation device 200.

[0071] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
