[0002] With the progress of space technology, in order to realize the development and utilization of lunar resources, landing on the moon and studying lunar soil has become a development trend. Specifically, the volatile components in lunar soil include H 2 , CO 2 , N 2 , CH 4 , NH 3 , H 2 O or rare gases, etc. These volatile components can not only reveal the process of planetary formation and evolution, but also be important resources for future lunar bases. Therefore, it is particularly important to analyze and study them. In order to improve the accuracy of the study of volatile components in lunar soil and avoid the loss and change of volatile components during the process of sampling and returning to the earth, it is necessary to study lunar soil in-situ on the moon. In the prior art, lunar soil is mostly abraded by friction and other methods, so that the volatile components in the lunar soil are volatilized for research. However, the volatilization speed of the volatile components in this way is relatively slow, so it is easy to leak, resulting in poor accuracy of experimental data; moreover, the time required for a single sample experiment is too long, and thus the time required for the entire research process is relatively long and the efficiency is low.

[0045] Refer to Figure 1 and Figures 11 - 14 , Figure 1 shows a schematic diagram of an on-line force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating provided by an embodiment of the present invention; Figure 11 shows Figure 1 a schematic diagram of the frame 100, the collector 200, the heating assembly 300, the first driving assembly 400, the second driving assembly 500 and the blanking plate 600 in the on-line force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating shown in

[0046] Figure 12 shows Figure 11 a sectional view taken along line D-D shown in Figure 13 shows Figure 12 a partial enlarged view at position E shown in Figure 14 shows Figure 1 a schematic diagram of the collector 200 in the on-line force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating shown in

[0047] An embodiment of the present invention provides an online force-controlled rotary direct-push seal force-applying mechanism for in-situ lunar soil heating, which includes a frame 100, a collector 200, a heating assembly 300, and a first drive assembly 400. The collector 200 is used to carry lunar soil; the heating assembly 300 includes a heating shell 310 and a heating furnace body 320; the heating shell 310 is fixedly connected to the frame 100, and the heating shell 310 is configured with a heating chamber 311, and the heating shell 310 is also configured with a ventilation pipe 312 that passes through the heating chamber 311, and the ventilation pipe 312 is used to communicate with a gas analyzer; the heating furnace body 320 includes a supporting portion 321, and the supporting portion 321 is used to support the collector 200; the first drive assembly 400 includes a fixed seat 410, The fixing seat 410 is slidably connected to the frame 100, and the fixing seat 410 is fixedly connected to the side of the heating furnace body 320 away from the supporting portion 321. The fixing seat 410 can drive the heating furnace body 320 to approach a first preset position relative to the heating shell 310; so that the heating furnace body 320 can be accommodated in the heating cavity 311; and the heating furnace body 320 can be sealed and abutted against the heating shell 310, so that the heating cavity 311 is a closed cavity; the heating furnace body 320 can perform a heating operation on the collector 200 located in the closed cavity.

[0048] When the lunar soil on the moon is analyzed in situ by the online force-controlled rotary direct-push sealing force-applying mechanism for in-situ lunar soil heating provided by the present invention, the supporting portion 321 of the heating furnace body 320 supports the collector 200, and the collector 200 carries the lunar soil. The heating furnace body 320 is driven by the fixing seat 410 of the first driving assembly 400 to approach the first preset position relative to the heating shell 310. Specifically, the first preset position is a position where the sealing ring 322 can be sealed and abutted with the heating shell 310, and the heating furnace body 320 is accommodated in the heating chamber 311, so that the heating furnace body 320 is accommodated in the heating chamber 311, and the heating furnace body 320 is sealed and abutted with the heating shell 310, and the heating chamber 311 is a closed chamber. At this time, the heating furnace body 320 heats the collector 200 located in the closed chamber, and the volatile matter in the lunar soil is volatilized under the heating action, and flows to the gas analyzer through the vent pipe 312 on the heating shell 310 for analysis. Since the present mechanism heats the lunar soil in a closed chamber by means of a heating furnace body 320 when conducting in-situ analysis on the volatiles in the lunar soil, the volatiles are less likely to leak in the closed chamber, and the content of the volatiles flowing into the gas analyzer is more accurate, thereby allowing the analysis of the volatile content of the lunar soil to be more accurate. Furthermore, since the heating furnace body 320 heats the lunar soil faster than the abrasion method, the volatiles in the lunar soil evaporate faster, and thus the time required for a single experiment on the lunar soil in each collector 200 is shorter, thereby allowing the entire research process to take less time and be more efficient.

[0049] Specifically, the collector 200 is configured with a cavity for accommodating lunar soil, and the cavity is in communication with the external environment. Therefore, when the collector 200 is heated, the volatile components of the lunar soil can volatilize into the sealed cavity through the cavity and flow into the gas analyzer through the ventilation pipe 312 on the heating housing 310.

[0050] In one specific embodiment, the supporting part 321 is configured with a plug-in part, and the collector 200 is configured with a mounting hole 210. By inserting the plug-in part into the mounting hole 210, the supporting part 321 can be sleeved and clamped with the collector 200. It should be noted that the plug-in part and the hole wall of the mounting hole 210 are in clearance fit. Therefore, after the analysis and detection of the lunar soil in the collector 200 carried on the supporting part 321 are completed, the collector 200 and the supporting part 321 are easy to separate, and it is easy to complete the operation of discarding the sample of the collector 200.

[0051] It should be noted that the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism can also be used for the analysis and detection of soil on other celestial bodies, such as Venus, Mars, etc. There is no limitation in this regard. This solution is only described by taking the moon as an example.

[0052] The following specifically describes the structure of the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism. Please refer to Figures 2 - 10 , Figure 2 shows Figure 1 the front view of the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism shown in Figure 3 shows Figure 1 the schematic diagram of the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism shown in Figure 4 shows Figure 1 the schematic diagram of the delivery pipe 710 in the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism shown in Figure 5 shows the installation schematic diagram of the frame 100, heating assembly 300, first drive assembly 400, second drive assembly 500 and blanking plate 600 in the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism shown in 1; Figure 6 shows Figure 5 the partial enlarged view of the A position shown in Figure 7 shows Figure 1 the schematic diagram of the heating assembly 300, first drive assembly 400, delivery pipe 710, first sensor 910 and second sensor 920 in the in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism shown in Figure 8 shows Figure 7 the partial enlarged view of the B position shown in Figure 9 shows Figure 7The right side view of the heating assembly 300, the first driving assembly 400, the delivery pipe 710, the first sensor 910 and the second sensor 920 in the online force-controlled rotary direct-thrust seal force-applying mechanism for in-situ lunar soil heating is shown; Figure 10 Shows Figure 9 A local enlarged view of point C is shown.

[0053] See also Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 11 The first driving assembly 400 of the online force-controlled rotary direct-thrust seal force-applying mechanism for in-situ lunar soil heating provided by one embodiment of the present invention further includes a first driving member 420 and at least two guide rods 430. The first driving member 420 is mounted on the frame 100. The power output end of the first driving member 420 is connected to the fixing seat 410. The two guide rods 430 are spaced apart along the length direction of the frame 100. Specifically, the length direction of the frame 100 is Figure 1 In the yy' direction, the fixing seat 410 is slidably mounted on the guide rod 430 and can slide along the extension direction of the guide rod 430 itself under the drive of the first driving member 420.

[0054] Since the fixed seat 410 is slidable by two guide rods 430 arranged at intervals along the length direction of the frame 100, when the fixed seat 410 drives the heating furnace body 320 to move relative to the heating shell 310, the entire movement process is not only stable, but also the parallelism of the fixed seat 410 is well maintained. When the heating furnace body 320 moves to seal and abut with the heating shell 310, due to the good parallelism of the fixed seat 410, the parallelism of the heating furnace body 320 installed thereon is good, and then when the heating furnace body 320 is driven by the fixed seat 410 and approaches the heating shell 310, the sealing connection at the abutment between the heating furnace body 320 and the heating shell 310 will be good, and finally the sealing performance in the closed cavity will be good. When the lunar soil is heated in the heating chamber 311, the volatile matter is not easy to leak from the abutment between the heating furnace body 320 and the heating shell 310, so that the accuracy of the analysis of the volatile content of the lunar soil is high. Specifically, the first driving member 420 can be a motor or a cylinder.

[0055] See also Figure 12 In one specific embodiment, the first driving assembly 400 also includes a screw rod 450, one end of which is connected to the side of the fixed seat 410 away from the heating furnace body 320, and the other end of the screw rod 450 is connected to the first driving member 420. The screw rod 450 is driven to rotate by the first driving member 420, thereby driving the fixed seat 410 to slide along the extension direction of the guide rod 430 itself.

[0056] In still another embodiment, the first driving assembly 400 further includes two gears. One of the gears is sleeved and fixed on the power output end of the first driving member 420, and the other gear is sleeved and fixed on the side of the lead screw 450 away from the heating furnace body 320. Through the meshing transmission of the two gears, the power of the first driving member 420 is transmitted to the lead screw 450 to drive the lead screw 450 to rotate about its own axis.

[0057] Please refer to Figure 13 , the heating furnace body 320 of the online force-controlled rotary direct-push sealing force-applying mechanism for in-situ lunar soil heating provided by an embodiment of the present invention further includes a sealing ring 322. The sealing ring 322 is sleeved on the heating furnace body 320. When the heating furnace body 320 approaches the heating outer shell 310 to a first preset position, the sealing ring 322 can be in sealing contact with the heating outer shell 310 at this time, so that the sealing effect of the heating furnace body 320 and the heating outer shell 310 is better, and thus the sealing performance of the heating cavity 311 as a closed cavity is better.

[0058] In one embodiment, the online force-controlled rotary direct-push sealing force-applying mechanism for in-situ lunar soil heating further includes a conveying assembly. The conveying assembly is slidably connected to the frame 100, and the conveying assembly is used to convey the collector 200 to the supporting portion 321 of the heating furnace body 320. The collector 200 is conveyed to the supporting portion 321 of the heating furnace body 320 through the conveying assembly, so that the heating furnace body 320 can drive the collector 200 to move into the heating cavity 311 of the heating outer shell 310 for heating operation, which is very simple and convenient.

[0059] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 9 , the conveying assembly of the online force-controlled rotary direct-push sealing force-applying mechanism for in-situ lunar soil heating provided by an embodiment of the present invention includes a conveying pipe 710. The conveying pipe 710 is slidably connected to the frame 100 so that the conveying pipe 710 can approach or move away from the supporting portion 321; the conveying pipe 710 is configured with a conveying cavity having an opening. The collector 200 is accommodated in the conveying cavity and can slide relative to the cavity wall of the conveying cavity. The collector 200 can slide to the supporting portion 321 through the opening of the conveying cavity. Since the conveying pipe 710 is slidably connected to the frame 100, the conveying pipe 710 can move closer to the supporting portion 321. When the conveying pipe 710 moves closer to the supporting portion 321 to a preset position, the collector 200 accommodated in the conveying cavity slides relative to the cavity wall of the conveying cavity, so that the collector 200 can slide to the supporting portion 321 through the opening of the conveying cavity.

[0060] In one embodiment, the conveying assembly further includes a driving member and a conveying member. The driving member is connected to the conveying pipe 710, and the power output end of the driving member is connected to the conveying member. The conveying member is connected to the collector 200 in the conveying cavity. The driving member is used to drive the conveying member to move, thereby driving the collector 200 in the conveying cavity to slide relative to the cavity wall of the conveying cavity. Specifically, the driving member can be a motor or a cylinder, and the conveying member can be a conveyor belt or a conveyor chain, etc.

[0061] Please refer to Figure 5 , the on-line force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating provided by an embodiment of the present invention further includes a second driving assembly 500. The second driving assembly 500 is installed on the frame 100. The second driving assembly 500 is connected to the fixed seat 410. The second driving assembly 500 is used to drive the fixed seat 410 to rotate around the rotation axis of the fixed seat 410; when the first driving assembly 400 drives the heating furnace body 320 to move away from the heating outer shell 310 to a second preset position, and the second driving assembly 500 drives the fixed seat 410 to rotate around its own rotation axis to a third preset angle, the supporting portion 321 can be opposite to the opening of the conveying cavity, so that the collector 200 can slide along the cavity wall of the conveying cavity to the supporting portion 321. Specifically, the third preset angle is the angle at which the supporting portion 321 is opposite to the opening of the conveying cavity. By driving the fixed seat 410 to rotate around the axis of the fixed seat 410 by the second driving assembly 500, the supporting portion 321 is opposite to the opening of the conveying cavity. Then, when the collector 200 slides along the cavity wall of the conveying cavity to the supporting portion 321, the collector 200 can be more easily sleeved and clamped with the supporting portion 321, and the collector 200 is not easily dropped before analysis and detection, thereby avoiding the waste of the lunar soil carried inside it.

[0062] Please refer to Figure 5 and in combination with Figure 6, the second driving assembly 500 of the online force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating provided by an embodiment of the present invention includes a second driving member, a rack 510, and a sector gear 520; the second driving member is installed on the frame 100, and the power output end of the second driving member is connected to the sector gear 520. The rack 510 is fixedly connected to the frame 100, the sector gear 520 is fixedly connected to the fixed seat 410, and the sector gear 520 meshes with the rack 510; the second driving member is used to drive the sector gear 520 to rotate around its own rotation axis, so as to drive the fixed seat 410 to rotate around the rotation axis of the fixed seat 410. By driving the sector gear 520 to rotate through the second driving member, the fixed seat 410 is further driven to rotate around its own rotation axis, so that the heating furnace body 320 fixedly connected to the fixed seat 410 can rotate synchronously, and finally the supporting part 321 on the heating furnace body 320 is opposite to the opening of the conveying cavity of the conveying pipe 710. At the same time, due to the meshing of the sector gear 520 and the rack 510, the rotation angle of the fixed seat 410 is relatively accurate, and the position where the supporting part 321 is opposite to the opening of the conveying cavity is more accurate. Specifically, the second driving member can be a motor or a cylinder, etc.

[0063] Please refer to Figures 5 - 11 , the first driving assembly 400 of the online force-controlled rotary direct-push sealing force application mechanism for in-situ lunar soil heating provided by an embodiment of the present invention further includes a guiding slider 440. The guiding slider 440 is slidably sleeved on the guiding rod 430. An avoidance groove 441 is formed by the guiding slider 440 being recessed inward along the height direction of the frame 100. Specifically, the height direction of the frame 100 is Figure 1 or Figure 7 the zz' direction in; the sector gear 520 is rotatably connected to the guiding slider 440, and a lapping portion 411 is protruded outward from the sector gear 520 along the length direction of the frame 100. Specifically, the length direction of the frame 100 is Figure 1 or Figure 7 the yy' direction in, and the lapping portion 411 can be at least partially received in the avoidance groove 441; when the sector gear 520 drives the fixed seat 410 to rotate around the rotation axis of the fixed seat 410, the lapping portion 411 can rotate in the avoidance groove 441.

[0064] By providing the lapping portion 411 and the avoidance groove 441 on the sector gear 520 and the guiding slider 440, when the sector gear 520 drives the fixed seat 410 to rotate, it can avoid the collision between the sector gear 520 and the fixed seat 410, thereby avoiding damage. Moreover, since the sector gear 520 is convexly provided with the lapping portion 411 along the length direction of the frame 100, the center of gravity of the entire sector gear 520 can be easily located at the center position of its own structure, which is relatively balanced. The sector gear 520 is not likely to become a cantilever beam structure, so the sector gear 520 itself is not likely to deform, and thus the parallelism of the fixed seat 410 fixedly connected thereto is maintained well. When the heating outer shell 310 and the heating furnace body 320 are in sealed contact, the sealing performance of the sealed cavity formed by the heating cavity 311 is also good.

[0065] Please refer to Figure 7 、 Figure 9 and Figure 10 As shown in, an in-situ lunar soil heating on-line force-controlled rotary direct-push sealing force application mechanism provided by an embodiment of the present invention further includes a first sensor 910. The first sensor 910 is installed on the frame 100 and is located between the frame 100 and the guiding slider 440. A first abutting wheel 911 is provided on the first sensor 910. An abutting inclined surface 442 is formed on one side of the guiding slider 440 close to the first sensor 910. When the guiding slider 440 slides along the extension direction of the guiding rod 430 to the second preset position, the first abutting wheel 911 can abut against the abutting inclined surface 442, and then it can be determined by the first sensor 910 whether the heating furnace body 320 has moved to the second preset position at this time. Specifically, the second preset position is the position where the heating furnace body 320 is completely separated from the heating outer shell 310, and when the fixed seat 410 rotates around the rotation axis of the fixed seat 410 to the third preset angle, the supporting portion 321 of the heating furnace body 320 is opposite to the opening of the conveying pipe 710 of the conveying assembly. Through the action of the first sensor 910, the position of the heating furnace body 320 can be accurately identified, and then the moving and staying position of the heating furnace body 320 during the moving process can be more accurate, so that when the fixed seat 410 rotates around the rotation axis of the fixed seat 410 to the third preset angle, the supporting portion 321 of the heating furnace body 320 is more accurately opposite to the opening of the conveying pipe 710 of the conveying assembly.

[0066] Please refer to Figure 1 、 Figure 2 and Figure 9The online force-controlled rotary direct-push seal force-applying mechanism for in-situ lunar soil heating provided by one embodiment of the present invention further includes a first stopper 810 and a second stopper 820; the first stopper 810 is mounted on the delivery pipe 710; the second stopper 820 is mounted on the frame 100, and the first stopper 810 cooperates with the second stopper 820 to limit the moving distance of the delivery pipe 710 relative to the supporting portion 321. By providing the first stopper 810 and the second stopper 820, the delivery pipe 710 will not collide with the supporting portion 321, thereby avoiding damage to the delivery pipe 710 and the supporting portion 321.

[0067] In one specific embodiment, see Figure 3 and Figure 4 The delivery tube 710 is provided with a plug-in end 711 on one side close to the supporting portion 321. The first limit member 810 is formed by the delivery tube 710 protruding outwardly along its radial direction, and the diameter of the first limit member 810 on the side facing the plug-in end 711 of the delivery tube 710 is gradually reduced. The second limit member 820 is constructed with a limit hole 821. The hole wall of the limit hole 821 is provided with a limit arm 822 along its axial direction and on one side facing the delivery tube 710, and the limit arm 822 is gradually expanded on one side facing the delivery tube 710. When the delivery tube 710 approaches a certain distance relative to the supporting portion 321, the first limit member 810 can be limited by the limit arm 822, thereby preventing the delivery tube 710 from getting closer to the supporting portion 321. For details, please refer to Figure 3 The number of the limiting arms 822 is 6, and the 6 limiting arms 822 are arranged at intervals along the circumference of the limiting hole 821 to limit the moving distance of the conveying tube 710.

[0068] In another specific embodiment, one of the first limit member 810 and the second limit member 820 is a limit switch, and the other is a limit sensor sheet, and the limit sensor sheet and the limit switch cooperate to limit the moving distance of the conveying tube 710 relative to the supporting portion 321. Specifically, the limit switch can be a Hall sensor or an infrared sensor, etc., and the limit sensor sheet is adapted thereto.

[0069] See also Figure 5 and Figure 11 The online force-controlled rotary direct-push seal force-applying mechanism for in-situ lunar soil heating provided by one embodiment of the present invention further includes a blanking plate 600, which is connected to the frame 100 and is arranged on the side of the fixed seat 410 away from the heating furnace body 320. The blanking plate 600 is constructed with a guide sliding slope 610 inclined from top to bottom along the height direction of the frame 100. Specifically, the height direction of the frame 100 is Figure 1 or Figure 7in the zz' direction. After the heating operation of the collector 200 is completed, the fixed seat 410 can drive the heating furnace body 320 to move away from the heating outer shell 310 to a third preset position relative to the heating outer shell 310, and the third preset position is the blanking position of the collector 200; and the second driving assembly 500 drives the fixed seat 410 to rotate around its own rotation axis to a first preset angle. Specifically, the first preset angle is the angle at which the collector 200 is separated from the supporting portion 321. For example, the included angle between the rotation axis of the fixed seat 410 and the vertical plane is 60°, so that the collector 200 is separated from the supporting portion 321 and slides to the surface of the celestial body through the guiding inclined surface 610.

[0070] When the heating operation of the collector 200 is completed, at this time, the fixed seat 410 drives the heating furnace body 320 to move away from the heating outer shell 310 to a third preset position relative to the heating outer shell 310. Specifically, the third preset position is the blanking position of the collector 200, that is, the supporting portion 321 is flush with the blanking plate 600 or slightly higher than the blanking plate 600. Then the second driving assembly 500 drives the fixed seat 410 to rotate around its own rotation axis to a first preset angle, so that the collector 200 can be separated from the supporting portion 321. Furthermore, under the action of gravity, the collector 200 slides to the surface of the celestial body through the guiding inclined surface 610, thus completing the sample discarding operation. Then, the analysis and detection of the volatile components of the lunar soil in the next collector 200 can be carried out.

[0071] Please refer to Figure 7 , an in-situ lunar soil heating online force-controlled rotary direct-push sealing force application mechanism provided by an embodiment of the present invention further includes a second sensor 920. The second sensor 920 is installed on the frame 100 and located between the frame 100 and the guiding slider 440. The working principle of the second sensor 920 is the same as that of the first sensor 910, and will not be elaborated here. The second sensor 920 is used to determine whether the heating furnace body 320 moves to the third preset position. Through the action of the second sensor 920, the position of the heating furnace body 320 can be more accurately identified. Furthermore, the moving and staying position of the heating furnace body 320 during the moving process can be more accurate, so that when the fixed seat 410 rotates around the rotation axis of the fixed seat 410 to the first preset angle, the collector 200 can easily slide to the surface of the celestial body through the guiding inclined surface 610.
