Description

Technical Field

[0002] In the context of large-scale lunar exploration activities, lunar energy supply has become a primary issue. At present, the energy and power supply of lunar exploration equipment mainly relies on solar energy and nuclear energy. Solar energy can only be used during the lunar day, while nuclear batteries have low output energy and can only meet the needs of low-power scientific research instruments. Therefore, it is difficult to provide sustainable energy security for large-scale lunar exploration activities by relying solely on solar energy or nuclear batteries. It is urgent to develop new technologies for lunar in-situ energy supply.

[0003] In fact, when the depth of the lunar surface exceeds 1m, the lunar soil or lunar rock layer is a constant temperature layer, and there is a large temperature difference between the constant temperature layer and the lunar surface; converting this temperature difference into energy that can be directly used on the moon is of great significance to the realization of in-situ energy supply for lunar-based activities, and the development of lunar geothermal energy is a very promising direction. On the other hand, high-temperature heat (1000℃) will be generated during lunar-based drilling. As a potential source of energy, there are no reports on heat recovery for lunar-based coring and prospecting. Using the high-temperature heat generated during lunar-based coring drilling to generate electricity in real time can achieve the dual effects of reducing the drill bit temperature and in-situ power generation while drilling, promote the safe drilling of lunar-based coring, and provide continuous energy supply for lunar-based exploration activities.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In the context of large-scale lunar exploration activities, lunar energy supply has become a primary issue. At present, the energy and power supply of lunar exploration equipment mainly relies on solar energy and nuclear energy. Solar energy can only be used during the lunar day, while nuclear batteries have low output energy and can only meet the needs of low-power scientific research instruments. Therefore, it is difficult to provide sustainable energy security for large-scale lunar exploration activities by relying solely on solar energy or nuclear batteries. It is urgent to develop new technologies for lunar in-situ energy supply.

[0022] Thermovoltaic power generation technology is a process that directly converts thermal energy into electrical energy, that is, the heat generated by the temperature difference between high and low temperatures is used to convert mobile thermal energy into electrical energy. It is an effective energy conversion method that can work in extreme environments. Since the moon is in an extreme vacuum and waterless environment, lunar-based drilling and coring exploration is actually a friction heat generation process of waterless dry drilling. The heat in the hole cannot be effectively discharged, and the maximum temperature of the drill bit can reach 1000°C. Recycling the high-temperature friction heat generated by lunar-based dry drilling can simultaneously achieve lunar-based in-situ power generation and effective coring exploration. In recent years, with the deepening of lunar exploration, human demand for lunar energy has become increasingly severe, and the existing lunar energy sources have obvious limitations. There have been no reports on heat recovery for lunar-based drilling and coring exploration. Using the high-temperature heat generated during lunar-based coring drilling to generate electricity in real time can achieve the dual effects of reducing drill bit temperature and in-situ power generation while drilling, promote the safe drilling of lunar-based coring, and provide continuous energy supply for lunar-based exploration activities.

[0023] Reference Figures 1 to 3 The present invention discloses a lunar-based coring prospecting in-situ real-time power generation device while drilling, comprising: a drilling sampling mechanism, the drilling sampling mechanism is used to drill into the lunar soil / rock, and the drilling sampling mechanism is also used to perform heat exchange with the lunar soil / rock; A phase-change heat-conducting mechanism, one end of which is disposed in the drilling and sampling mechanism and is used for heat exchange with the drilling and sampling mechanism; The in-situ power generation mechanism is arranged between the drilling and sampling mechanism and the phase change heat conduction mechanism. The in-situ power generation mechanism can switch between the first power generation mode and the second power generation mode according to the temperature difference between the drilling and sampling mechanism and the phase change heat conduction mechanism. In the first power generation mode, friction heat is generated between the drilling and sampling mechanism and the lunar soil / rock. At this time, the drilling and sampling mechanism is the hot end and the phase change heat conduction mechanism is the cold end; in the second power generation mode, the drilling and sampling mechanism is located inside the lunar soil / rock. During the lunar day, the drilling and sampling mechanism is the cold end and the phase change heat conduction mechanism is the hot end. During the lunar night, the phase change heat conduction mechanism is the cold end and the drilling and sampling mechanism is the hot end. In the present invention, lunar soil / rock is sampled by a drilling sampling mechanism. When the drilling sampling mechanism is sampling, it generates a large amount of heat by friction with the lunar soil / rock. At this time, the drilling sampling mechanism acts as a hot end. On the one hand, the phase change heat conduction mechanism conducts the heat of the drilling sampling mechanism to reduce the temperature of the drilling sampling mechanism. On the other hand, the phase change heat conduction mechanism acts as a cold end. At this time, the in-situ power generation mechanism generates electricity through the temperature difference between the drilling sampling mechanism and the phase change heat conduction mechanism. After the sampling is completed, the drilling sampling mechanism is located inside the lunar soil / rock. During the lunar day, the drilling sampling mechanism is the cold end and the phase change heat conduction mechanism is the hot end. During the lunar night, the phase change heat conduction mechanism is the cold end and the drilling sampling mechanism is the hot end. The in-situ power generation mechanism generates electricity through the temperature difference between the drilling sampling mechanism and the phase change heat conduction mechanism. In the present application, electricity is generated by recovering the heat of the drilling sampling mechanism during sampling, and a thermovoltaic power generation device is integrated to achieve continuous power generation, which is not affected by the working conditions and the time of the lunar day / night.

[0027] A further optimized solution is that the drilling sampling mechanism includes an outer shell 5, one end of the phase change heat conduction mechanism is arranged in the outer shell 5, the outer shell 5 is also used for conducting heat, the bottom end of the outer shell 5 is detachably connected with a drill bit 6, and a sampling hole for sampling is opened on the drill bit 6. The heat of the drill bit 6 during sampling is transferred to the outer shell 5, wherein the outer shell 5 is a heat-conducting shell made of heat-conducting material; the drill bit 6 and the outer shell 5 are connected by a threaded connection, and extending the length of the thread can effectively increase the heat conduction efficiency between the drill bit 6 and the outer shell 5.

[0028] According to a further optimized solution, the phase-change heat-conducting mechanism comprises a heat-conducting pipe 3 , and the bottom end of the heat-conducting pipe 3 is coaxially penetrated in the outer shell 5 .

[0029] A further optimized solution is that the in-situ power generation mechanism includes a plurality of thermoelectric module groups, which are arranged between the outer wall of the heat pipe 3 and the inner wall of the outer shell 5, and the plurality of thermoelectric module groups are arranged at equal intervals from top to bottom along the length direction of the outer shell 5. The thermoelectric module group includes a plurality of thermoelectric modules 4, and the plurality of thermoelectric modules 4 are arranged at equal intervals in the circumferential direction, and the two ends of the thermoelectric modules 4 are respectively in contact with the outer wall of the heat pipe 3 and the inner wall of the outer shell 5.

[0030] According to a further optimization scheme, the heat radiation mechanism includes a plurality of radiation plates 1, which are circumferentially evenly spaced on the outside of the heat pipe 3, and the plurality of radiation plates 1 are all located on the lunar surface, and the radiation plates 1 are used to transfer heat to the heat pipe 3.

[0031] According to a further optimization scheme, the heat preservation mechanism includes: a vacuum insulation layer 2, which is arranged on the outside of the heat-conducting pipe 3, and a vacuum cavity is formed between the vacuum insulation layer 2 and the heat-conducting pipe 3 for insulating the heat-conducting pipe 3.

[0032] According to a further optimized solution, the power mechanism includes a drill 7 , the output shaft of the drill 7 is transmission-connected to the heat pipe 3 via a joint 9 , and the radiation plate 1 is detachably connected to the outer side wall of the joint 9 .

[0033] A further optimized solution is provided, wherein the heat pipe 3 comprises a heat pipe 3.1, the bottom end of the heat pipe 3.1 is coaxially penetrated in the outer shell 5, the top end of the heat pipe 3.1 is connected to the joint 9, the outer side of the heat pipe 3.1 is provided with a heat preservation mechanism, a heat conducting structure 3.2 is provided inside the heat pipe 3.1 / on the inner side wall of the heat pipe 3.1, and the radiation plate 1 is used to transfer heat to the heat conducting structure 3.2, wherein the heat conducting structure 3.2 is a capillary structure, which is opened inside the heat pipe 3.1 or arranged on the inner side wall of the heat pipe 3.1, and a heat conducting medium (working fluid) is provided in the heat conducting structure 3.2 to accelerate the heat transfer.

[0034] Working principle: When the drill tool drills and cores in the lunar environment, since there is no circulating medium in the borehole, it is actually a frictional heat generation process of waterless dry drilling, and the drill end can generate a high temperature of nearly 1000°C. The high temperature generated by the drill bit 6 is transmitted to the shell 5, and a vacuum insulation layer 2 is arranged on the outside of the heat pipe 3 to form a heat preservation cavity to avoid heat conduction to the lunar soil / rock area as much as possible. The contact between the thermoelectric module 4 and the shell 5 forms a hot end, and the contact between the thermoelectric module 4 and the heat pipe 3 forms a cold end. When one end of the heat pipe 3 is heated by the heat source conducted by the shell 5, the internal working fluid absorbs heat and evaporates to form steam; the steam flows rapidly to the colder end along the heat conducting structure 3.2 inside the heat pipe 3.1 under the impetus of the capillary effect; at the colder end, the steam condenses into liquid when it encounters cold and releases heat. The condensed liquid flows back to the hotter end through the heat conducting structure 3.2, completing the cycle and realizing the transfer of heat from the hot end to the cold end. Through the above process, the heat exchange between the high temperature heat generated by the drill bit during drilling and the heat source on the lunar surface can be achieved. The temperature difference between the high temperature generated by lunar-based core drilling and exploration and the lunar surface can be converted into electrical energy through an integrated thermovoltaic generator. The thermoelectric module is a power generation device that directly converts thermal energy into electrical energy using the Seebeck effect.

[0035] When the drilling is completed, during the lunar day / night, the two sides of the thermoelectric module 4 absorb heat from the lunar soil / rock constant temperature layer and the lunar surface respectively. During the lunar day, the temperature can reach up to 127°C, and the temperature of the lunar surface is conducted through the radiation plate 1 to form a hot end, forming a temperature difference with the cold end of the lunar soil / constant temperature layer of about -20°C; during the lunar night, the temperature can reach down to -183°C, and the heat of the lunar soil / rock constant temperature layer of about -20°C is conducted to the outer shell 5 to form a hot end, and the temperature of the lunar surface is conducted through the radiation plate 1 to form a cold end. The temperature difference between the outer shell 5 and the lunar soil / rock constant temperature layer during the lunar day / night is used to convert the temperature difference into electrical energy through the integrated thermovoltaic generator. The device can realize uninterrupted and continuous power generation, whether during drilling and coring or after drilling is completed, and is not affected by working conditions and lunar day / night time.

[0036] The equipment installation and fixing process of the present invention is as follows: the first step is to transport the device to the target location through the lunar exploration equipment; the second step is to accurately locate the target location and fix the device in the lunar soil / rock through the lunar exploration equipment; the third step is to start the device and drill into the lunar soil / rock to reach a predetermined depth for sampling; the fourth step is to generate electricity through the in-situ power generation mechanism during the sampling process, and the output power is used to power the drilling instrument in the hole or the lunar surface instrument and equipment; the fifth step is to store the core sample in a specific storage cabin after the sampling is completed, and to fix the heat pipe 3 and the vacuum insulation layer 2 in the lunar soil / rock by a fixing device to construct a temporary or permanent in-situ power generation system. At the same time, multiple power generation devices can be connected in series to continuously provide power for the lunar surface instruments and equipment.
