Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of extraterrestrial water development, in particular to an extraterrestrial water ice in-situ synthesis and exploitation simulation device and method. BACKGROUND

[0002] There are a large amount of water ice, methane sea, methane hydrate, ammonia hydrate and other ice-like or ice-like substances on extraterrestrial planets such as Mars, the Moon and Titan, which are important sources of energy resources such as methane, hydrogen and ammonia, and life resources such as water in the future process of human migration and exploration.

[0003] However, the structure of extraterrestrial water ice is complex, the mineral composition is complex, the temperature and pressure are extreme, and the gravity is low, which leads to the exploitation conditions being quite different from those on Earth. Therefore, the existing Earth water ice exploitation device cannot be effectively applied to the exploitation of extraterrestrial water ice.

[0004] Patent application No. 20211059469.1 discloses a lunar water ice exploitation method, which includes 6 steps. First, a neutron spectrometer in a movable base station at the edge of a shadow pit detects the location of the water ice in the pit. Then, meteorological blasting shells are fired at the detected location. Then, an anti-escape cover that can be deployed in the air is fired at the blasting location to cover the blasting pit. Then, a light collector in the base station guides sunlight to the blasting pit through the anti-escape cover. The water ice sublimated by the sunlight is collected by a cold trap collector in the anti-escape cover. After the collection is completed, it can be recycled into the base station. However, this method is mainly used for sublimation water ice collection and is difficult to implement under low gravity conditions.

[0005] Patent No. 202011933369.0 discloses a lunar polar region deep water ice sampling and detection device, which includes a mechanical arm, a detection bomb, a sampling assembly and a control unit. The detection bomb, the sampling assembly and the control unit are installed on the mechanical arm. The mechanical arm is used to control the penetration angle of the detection bomb and the spatial pose of the sampling assembly by changing its own configuration. An electromechanical interface connected to the detection bomb is provided on the mechanical arm, and the electromechanical interface is electrically connected to the control unit. The detection bomb is used to penetrate into the predetermined depth of the detection area in the form of kinetic energy after receiving the initiation instruction of the control unit. The hole formed during the penetration of the bomb head serves as a sampling channel for the sampling assembly. The sampling assembly is used to enter the sampling channel under the assistance of the mechanical arm to collect samples from the detection object on the side wall of the sampling channel. However, this patent is mainly used for sampling and is difficult to realize the exploitation and utilization of water ice.

[0006] The patent application with the patent application number 202211378585.1 discloses a system for extracting and utilizing water ice resources outside the earth and an implementation method thereof. The system comprises a drilling device for ice-containing regolith, a water ice light-heat extraction device, a steam condensation and collection device, a hydrogen-oxygen decomposition device, and a load platform. The drilling device for ice-containing regolith and the water ice light-heat extraction device are designed in an integrated manner. The drilling device for ice-containing regolith is connected to the steam condensation and collection device through a steam pipeline. The steam condensation and collection device is connected to the hydrogen-oxygen decomposition device through a liquid water pipeline. The drilling device for ice-containing regolith, the water ice light-heat extraction device, the steam condensation and collection device, and the hydrogen-oxygen decomposition device are installed on the load platform. However, the structure of the patent application is relatively complex. Moreover, the patent is an equipment for on-site application, and the cost of on-site verification is extremely high. It is impossible to carry out indoor synthesis and preparation of water, ice, and combustible ice deposits and in-situ monitoring and mining. There is no recovery measurement system matched with the combustible ice mining. In addition, the light gathering and heating system is greatly affected by light, and it is impossible to carry out continuous mining.

[0007] The cost of extraterrestrial on-site water ice mining experiments is extremely high. Therefore, a simple structure is needed to simulate the in-situ synthesis and mining of extraterrestrial water ice in a low-temperature vacuum weightlessness environment. It can effectively be applied to indoor experiments and on-site applications of extraterrestrial water ice mining. It can also provide experimental and theoretical support for human extraterrestrial migration and exploration of energy and water resources. SUMMARY
