[0002] The moon holds vast potential for scientific exploration and abundant resources; therefore, humankind has never ceased its exploration of the moon. In lunar exploration missions, studying the properties and parameters of lunar soil is a necessary means to gain a deeper understanding of lunar geological information.

[0003] However, a common technical challenge in returning lunar soil samples to Earth is the lack of adequate fidelity processing of the lunar rock samples, particularly regarding temperature control. Given the significant temperature differences between day and night on the lunar surface, the obtained lunar core samples undergo drastic temperature changes after sampling. Furthermore, lunar rock samples from different locations experience varying temperature environments, requiring different fidelity-preserving temperatures. This temperature variation leads to the loss of compositional and geological information from the in-situ lunar rock samples, making it extremely difficult to obtain the original information from the lunar core.

[0033] Please see Figures 2 to 4The heating structure 500 is at least partially located within the accommodating cavity 211 and connected to the fixing base 202. The heating structure 500 radiates heat towards the lunar rock sample to maintain it at a predetermined temperature. It is understood that the heating end of the heating structure 500 is located within the accommodating cavity 211, enabling it to radiate heat to the lunar rock sample to heat it to a predetermined temperature, which is the ambient temperature of the lunar rock sample at the time of sampling. It is also understood that an end cap is provided at the opening to seal the accommodating cavity 211, preventing and hindering heat loss.

[0034] Please see Figures 2 to 4 The control structure 300 is used to control the heating of the heating structure 500, thereby not only controlling the temperature inside the accommodating cavity 211 to be within a reasonable fluctuation range, thus achieving heat preservation for the lunar rock sample, but also controlling the heat output of the heating structure 500 according to the ambient temperature at different locations, so as to ensure that the temperature inside the accommodating cavity 211 is the same as the ambient temperature of the lunar rock sample, thereby expanding the application range of the lunar soil in-situ environment heat preservation control device 100.

[0035] Please see Figures 2 to 4 The lunar soil in-situ environment heat preservation and control device 100 provided in this application embodiment includes a storage structure 200, a heating structure 500, and a control structure 300. By placing a lunar rock sample in the accommodating cavity 211 of the storage structure 200 and radiating heat into the accommodating cavity 211 through the heating structure 500, the temperature of the lunar rock sample in the accommodating cavity 211 can be kept consistent with the temperature of the environment it was in before sampling. Then, by controlling the heating of the heating structure 500 through the control structure 300, the lunar soil in-situ environment heat preservation and control device 100 can adapt to different temperature environments.

[0036] Please see Figures 2 to 4 Optionally, the lunar soil can be preserved by the lunar soil in-situ environment temperature control device 100, preventing the container 211 from shifting or falling off during the transportation of lunar mineral samples, and by measuring the ambient temperature of the lunar soil at its original location, the temperature inside the container 211 can be made the same as the temperature of the lunar soil at its original location.

[0041] Please see Figures 2 to 4 Optionally, the heating rod 520 can be a ceramic heating rod. A ceramic heating rod is an electrothermal device that utilizes ceramic materials. Its main function is to heat the ceramic using electrical energy to generate heat.

[0047] Please see Figures 2 to 4 It is also understandable that placing the heating end of the heating rod 520 in a liquid environment can prevent interference from radiation or other interference signals on the heating process of the heating rod 520 in the lunar environment, giving the heating structure 500 a certain ability to resist external environmental interference, and also making full use of the advantage of the large specific heat capacity of the first heat-conducting liquid 410 to make the temperature in the accommodating cavity 211 more stable.

[0048] In some embodiments, the sample storage tube 201 includes three splicing units 212, which are joined together in a circumferential direction to form the receiving cavity 211, and one end of each splicing unit 212 is connected to the fixing base 202.

Optionally, the fixing base 202 has a rotating structure, generally shaped like a frustum, with three fan-shaped frustums. Each protruding fan-shaped frustum has two 3.5mm through holes at its bottom, distributed circumferentially, and a groove 214 for wiring is provided at the bottom. The fixing base 202 and the three splicing units 212 are detachably connected and fixed using M3 screws and nuts.

[0056] Optionally, a light-absorbing layer can be coated on the outer surface of the heat pipe 110 to convert sunlight into heat energy while avoiding interference from external rays or sunlight to the internal components.

There are no restrictions here, and it can be selected according to the actual situation.
