Description

Technical Field

[0001] The invention belongs to the technical field of extraterrestrial body sampling and detection, and in particular relates to a temperature control and maintenance device, a force load testing device and a method for a lunar soil water ice simulant. Background Art

[0002] Since the 1960s, when researchers proposed the existence of water ice in the permanently shadowed lunar poles, a surge in interest in lunar regolith detection has emerged, making exploration of this region a strategic priority for major space powers. Over decades of technological advancement, extraterrestrial probes, using remote sensing methods such as radar, neutron spectroscopy, and spectroscopy, have initially confirmed the presence of varying amounts of water ice in the lunar surface, subsurface, and profiles at high latitudes. They speculate that this ice may exist as a mixture of ice and lunar regolith, or as water ice or bound water. However, the exact state of occurrence and its physical and chemical properties have yet to be definitively verified.

[0003] Currently, domestic and international scholars have conducted extensive research on the drilling and cutting of extraterrestrial regolith. Sun Jing et al. addressed the lack of a test platform for cutting performance testing of simulated lunar regolith in existing technologies and provided a single-edge linear cutting load characteristic test platform. To meet dynamic cutting requirements, Liu Rongqiang et al. proposed an orthogonal single-edge cutting force test system using a drop hammer and a cutting test bench. These studies focused on lunar rocks and dry lunar regolith, which differ significantly from regolith containing water ice. The occurrence morphology and mechanical properties of lunar regolith water ice are key research areas for future polar exploration and represent a key simulation technology that is difficult to achieve and control. Therefore, to address the issue of maintaining the temperature and morphology of existing lunar regolith water ice samples, it is necessary to design a device that simulates the polar lunar regolith state by coupling multiple factors, including the physical properties of lunar regolith water ice. Summary of the Invention

[0004] In view of this, the present invention aims to propose a temperature control and maintenance device for lunar soil water ice simulant to solve the problem of maintaining the temperature and morphology of existing lunar soil water ice simulant.

[0005] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0007] Furthermore, the latch assembly includes a sealing latch and a sealing latch opening, the sealing latch being fixed at the free end of the thermal insulation observation opening and closing plate, and the sealing latch opening being installed on the side of the low temperature environment box corresponding to the free end of the thermal insulation observation opening and closing plate.

[0008] Furthermore, a sample mold enclosure is provided at the upper end of the sample mold for keeping the surface edge of the simulated lunar soil sample intact.

[0009] Furthermore, a liquid nitrogen port is provided at a corner of the upper surface of the low-temperature environment box, and the liquid nitrogen port is connected to the funnel.

[0010] Furthermore, openings for evaporation of liquid nitrogen are provided at the four corners of the transparent cover.

[0011] Furthermore, the transparent cover is an acrylic transparent cover.

[0012] Furthermore, a sealing strip is provided on the thermal insulation observation opening and closing plate.

[0013] Compared with the prior art, the temperature control and maintenance device for lunar soil water ice simulant created by the present invention has the following beneficial effects:

[0014] (1) The temperature control and maintenance device for the lunar soil water ice simulant created by the present invention can isolate the lunar soil water ice sample from the outside air through the shielding effect of the low-temperature environment box, ensure its own water content is constant, and achieve good environmental heat insulation effect.

[0015] (2) The temperature control and maintenance device for the lunar soil and water ice simulant created by the present invention can make the lunar soil and water ice sample in the mold reach a lower temperature level (maximum below -190°C) by filling the refrigerant mold with refrigerant (liquid nitrogen) and then transferring heat to the lunar soil and water ice mold.

[0016] (3) The temperature control and maintenance device for the lunar soil and water ice simulant created by the present invention can realize the functions of temperature measurement and temperature control by embedding a temperature sensor inside the lunar soil and water ice sample, thereby ensuring that the lunar soil and water ice sample can maintain a relatively stable temperature and shape.

[0017] Another purpose of the present invention is to propose a low-temperature simulated lunar soil and water ice cutting force test device, which includes a horizontally arranged cutting force test platform, a frame vertically fixed on one side of the cutting force test platform, a force monitoring unit fixed on the cutting force test platform, a cutting drive unit installed on the frame, a vernier slide for changing the cutting position of the sample, and a temperature control and maintenance device for loading the above-mentioned lunar soil and water ice simulant on the vernier slide.

The cutting platform unit controls the output through the cutting servo control unit to control the cutting procedure of the cutting platform. The cutting servo control unit can effectively and stably propel the cutting mechanism to perform cutting motion.

[0021] (2) The present invention creates a low-temperature simulated lunar soil water ice cutting force load testing device, in which a force load monitoring unit collects and monitors the cutting force load of the interaction between the sample and the tool in real time; the force load monitoring unit can accurately measure the cutting force load.

[0022] (3) The present invention creates a low-temperature simulated lunar soil and water ice cutting force load test device. Through the setting of the vernier slide, it can realize multi-position cutting of lunar soil and water ice samples, and fully utilize the lunar soil and water ice samples. Multiple cutting can also increase the number of experimental groups, obtain more force load data, reduce random errors, and obtain relatively accurate cutting force loads.

[0023] Another purpose of the present invention is to propose a testing method for a low-temperature simulated lunar soil and water ice cutting force test device, which includes a liquid nitrogen tank providing refrigerant to fill the low-temperature environment box with liquid nitrogen through a flow pipe, cooling the simulated lunar soil sample immersed in the refrigerant, and a temperature sensor embedded in the simulated lunar soil sample to monitor the sample temperature of the simulated lunar soil sample in real time, thereby playing a role in temperature control.
