Description

Technical Field

[0001] This invention relates to the field of lunar soil oxygen production technology, and in particular to an automatic sublunar oxygen production device based on lunar soil and its usage method. Background Technology

[0002] The new round of lunar exploration focuses on locating, extracting, and utilizing energy and resources existing in space, converting them into key energy sources and products needed for deep space exploration or base construction missions—in-situ utilization of deep space resources. However, due to the unique high vacuum, low temperature difference, and high cost of Earth-Moon transportation on the lunar surface, existing equipment and methods for soil collection, oxygen extraction, and storage on Earth cannot be directly applied to the preparation and storage of oxygen in the lunar environment. Therefore, there is an urgent need to develop equipment specifically designed for the sustainable production, collection, and storage of oxygen in the lunar environment.

[0003] Therefore, utilizing the abundant lunar regolith particles on the lunar surface to produce oxygen is currently the main method used worldwide for lunar oxygen production. However, the large diurnal temperature range, high vacuum environment, and the need to avoid manual labor on the lunar surface pose challenges to the continuous production of oxygen. Existing lunar oxygen production methods are inefficient and inconvenient to operate. Therefore, it is extremely important to propose an automated lunar oxygen production device based on lunar regolith and its usage method. Summary of the Invention

[0057] Example 4:

[0058] A method for using an automated sublunar oxygen production device based on lunar soil, characterized by comprising the following steps:

[0059] S1 lunar soil collection and delivery:

[0060] The lunar soil was excavated from the lunar surface and transported to the interior of isolation box 4 using a soil-carrying and transporting mechanism.

[0061] S2 lunar soil melts upon heating:

[0062] After the lunar soil is transported into the isolation box 4, the isolation box 4 is sealed, and the lunar soil is heated and melted using the heating plate 8, while the sealing and stirring mechanism 5 is used for stirring.

[0063] S3 electrolytic oxygen production:

[0064] The molten lunar soil is electrolyzed to produce oxygen, and the produced oxygen is collected in the gas collection box 2.

[0065] Working principle:

[0066] When collecting and transporting lunar soil, the push unit 18 and the length adjustment unit 17 are activated, pushing the conveying pipe 14 to deflect downwards. At the same time, the telescopic rod 15 slides downwards along the length of the conveying pipe 14, causing the bucket 16 to extend downwards into the lunar soil. As the box 1 moves forward, the lunar soil enters the bucket 16. Then, the push unit 18 is activated, causing the conveying pipe 14 to deflect upwards. The scooped lunar soil slides along the telescopic pipe 15 and the conveying pipe 14 from the feed inlet on the box 1 into the interior of the box 1. Then, under the guidance and obstruction of the partition plate 12 and the baffle plate 11, it enters the interior of the isolation box 4. Before the lunar soil enters, the bottom sealing plate 6 at the bottom of the isolation box 4 seals the bottom of the isolation box 4. After the lunar soil enters the isolation box 4, the drive mechanism 7 is activated, and the sealing and stirring mechanism 5 seals the top of the isolation box 4.

[0067] When sealing the top of the isolation box 4, the sealing and stirring mechanism 5 moves forward under the action of the drive mechanism 7. At this time, the cover 61 and the support shaft 71 movably connected to the cover 61 move together. The limiting plate 74 at the end of the support shaft 71 moves along the limiting groove 58 towards the transition groove 59 and the open groove 510. When the limiting plate 74 moves from the transition groove 59 to the open groove 510, the limiting groove 58 does not restrict the limiting plate 74. At the same time, the gear 73 on the support shaft 71 contacts and meshes with the rack 511, thereby causing the support shaft 71 to rotate when it moves forward. When the support shaft 71 rotates, it will be horizontal. The stirring shaft 81 is flipped to a vertical position; at the same time, the push-pull rod 76 moves along the guide groove 3 54 towards the push groove 55 and the guide groove 4 56. When the push-pull rod 76 moves at the push groove 55, it moves towards the inside of the mounting groove 53, and then drives the locking rod 75 to move. The locking rod 75 extends out from the locking hole on the outer ring of the stirring shaft 81 and does not lock the stirring shaft 81. At the same time, when the stirring shaft 81 rotates with the support shaft 71, the plug plate 814 located at the top of the stirring shaft 81 deflects and extends into the docking plate at the bottom of the drive shaft 52, and plugs into the docking plate, so that the motor can make the stirring shaft 81 rotate and stir when it starts.

[0068] When the stirring shaft 81 rotates with the support shaft 71, the driven rod 817 of the adjusting ring 815 located on the outer ring of the stirring shaft 81 moves along the guide groove 63 to the transition groove 64 and the guide groove 65. At this time, the adjusting ring 815 moves towards the bottom of the stirring shaft 81 under the action of the driven rod 817. Then the adjusting ring 815 drives the push rod 83 slidably connected to it to move towards the bottom of the stirring shaft 81. Then the connecting rod 84 and the base 85 move downward. After that, the movable rod 86 moves downward. Then, under the action of the gear 89 and the rack 88, the rotating shaft 810 rotates, thereby causing the auxiliary rod 812 located at the bottom of the stirring shaft 81 to deflect outward from the stirring shaft 81, unfolding the auxiliary rod 81, so as to facilitate the full mixing of lunar soil during the stirring process.

[0069] Subsequently, under the action of heating plate 8, the lunar soil is heated to a molten state, and then the motor 9 is powered on. After being powered on, the oxides in the lunar soil are electrolyzed to generate oxygen. The generated oxygen is transported to the gas collection box 2 along the gas pipe 1.

[0070] During the day, solar energy is collected by the photovoltaic panels on the top of the container 1 as the energy source for oxygen production. At night, the lunar temperature decreases, and the gaseous oxygen inside the gas collection container 2 liquefies and then enters the storage container 3 through the gas pipe 2 for storage. This design can realize the entire process of lunar soil collection, oxygen production, collection, and storage in the lunar environment. The folding and retractable design during oxygen production allows for stirring and mixing of the lunar soil during heating, improving the heating efficiency and quality of the lunar soil and thus increasing oxygen production efficiency. It makes full use of lunar solar energy, lunar soil materials, and the temperature difference between day and night for the entire process of lunar oxygen production and storage. The equipment is simple and can be placed on a lunar rover for use as a mobile oxygen production device.

[0071] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
