Description

Technical Field

[0001] The present invention relates to the technical field of solid samples and volatile substance transportation and extraction, and particularly to a compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism. Background Art

[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 H2, CO2, N2, CH4, NH3, H2O or noble 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. When the study of volatile components in lunar soil is carried out in situ on the moon after the lunar soil sampling is completed, it is necessary to transport the sampler carrying lunar soil to a heating furnace for heating operation. In the prior art, when transporting the sampler, it is easy to have the situation that the sampler does not cooperate properly with the heating table. As a result, during the transportation of the sampler, the lunar soil is easy to spill from the loading cavity of the sampler, resulting in a large difference in the content of lunar soil in each sampler, and thus a large error in the final experimental results. Summary of the Invention

[0016] In one embodiment, the second detection arm includes a first stepped portion, a second stepped portion, and a third stepped portion connected in sequence; and the diameters of the first stepped portion and the third stepped portion are larger than the diameter of the second stepped portion;

[0017] A stepped hole is formed in the first mounting seat, at least part of the second stepped portion is accommodated in the stepped hole, and the first detection arm is movably sleeved on the second stepped portion and can abut against the first stepped portion;

[0018] The detection assembly further includes a first elastic member sleeved on the outer periphery of the second stepped portion, wherein the first elastic member is in a compressed state and abuts between the third stepped portion and a stepped wall of the stepped hole.

[0027] Beneficial effects of the present invention:

[0028] When conducting in-situ analysis and research on lunar soil on the moon, the compliant docking and guiding lunar soil encapsulation sample delivery-detection mechanism provided by the present invention is used to transport the collected lunar soil. Since a sampler is accommodated inside the sample delivery tube, and the sampler carries the lunar soil collected on the moon, at this time, the sample delivery tube moves closer to the feeding seat so that one end of the sample delivery tube can at least partially extend into the feeding cavity of the feeding seat. When the sample delivery tube moves relative to the feeding seat to the first preset position, the sample delivery tube performs a sample ejection operation at this time, so that the sampler can be separated from the sample delivery tube and pass through the feeding seat to cooperate with the heating table. Since in this process, each time the sample delivery tube performs a sample ejection operation, the sample delivery tube is in the first preset position relative to the feeding seat, the position of the sample delivery tube relative to the feeding seat always remains the same, so that the position of the sample delivery tube relative to the heating table also always remains the same. Furthermore, after the sampler is separated from the sample delivery tube, the sampler moves a specific length and then cooperates with the heating table. Since the movement distance of the sampler is relatively constant, the cooperation between the sampler and the heating table is good, and the lunar soil is not easily spilled from the bearing cavity of the sampler. Finally, the difference in the content of lunar soil in each sampler is small, the accuracy of the experimental results is high, and the error is small. Description of the Drawings

[0050] Refer to Figure 1 and Figures 9 - 14 , Figure 1 FIG. shows a schematic diagram of the cover plate 400 in an open state after the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism provided by an embodiment of the present invention is installed on the heating table 800; Figure 9 FIG. shows Figure 1 a schematic diagram of the relative position of the sample feeding seat 100, the detection component 200 and the rebound component 300 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 10 FIG. shows Figure 9 a top view of the relative position of the sample feeding seat 100, the detection component 200 and the rebound component 300 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 11 FIG. shows Figure 10 a cross - sectional view of the E - E position shown in Figure 12 FIG. shows Figure 1 a schematic diagram of the relative position of the sample delivery tube 700 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 13 FIG. shows Figure 12 a schematic diagram of the internal structure of the relative position of the sample delivery tube 700 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 14 FIG. shows Figure 13 a partial enlarged view of the F position shown in

[0051] The compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism provided by an embodiment of the present invention includes: a frame 600, a feeding seat 100, and a sample delivery tube 700. The feeding seat 100 is connected to the frame 600, and the feeding seat 100 is configured with a feeding cavity 110; the sample delivery tube 700 is configured with a sample delivery cavity 710, and a collector 720 is arranged in the sample delivery cavity 710, and the collector 720 is used to carry lunar soil; the sample delivery tube 700 can move closer to or away from the feeding seat 100, and one end of the sample delivery tube 700 can at least partially extend into the feeding cavity 110; when the sample delivery tube 700 moves closer to the feeding seat 100 and reaches the first preset position, the sample delivery tube 700 can perform a sample ejection operation, so that the collector 720 is separated from the sample delivery tube 700 and passes through the feeding seat 100 to cooperate with the heating table 800.

[0052] When in - situ analysis and research on lunar soil is carried out on the moon, the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism provided by the present invention is used to transport the collected lunar soil. Since the collector 720 is arranged inside the sample delivery tube 700, and the collector 720 carries the lunar soil collected on the moon, at this time, the sample delivery tube 700 is moved closer to the feeding seat 100 so that one end of the sample delivery tube 700 can at least partially extend into the feeding cavity 110 of the feeding seat 100. When the sample delivery tube 700 moves to the first preset position relative to the feeding seat 100, at this time, the sample delivery tube 700 performs a sample ejection operation so that the collector 720 can be separated from the sample delivery tube 700 and passes through the feeding seat 100 to cooperate with the heating table 800. Since in this process, each time the sample delivery tube 700 performs a sample ejection operation, the sample delivery tube 700 is in the first preset position relative to the feeding seat 100, the position of the sample delivery tube 700 relative to the feeding seat 100 always remains the same, so that the position of the sample delivery tube 700 relative to the heating table 800 also always remains the same. Furthermore, after the collector 720 is separated from the sample delivery tube 700, the collector 720 moves a specific length and then cooperates with the heating table 800. Since the movement distance of the collector 720 is relatively constant, the cooperation between the collector 720 and the heating table 800 is better, and the lunar soil is not easily spilled from the bearing cavity of the collector 720. Finally, the difference in the content of lunar soil in each collector 720 is small, and the accuracy of the experimental results is high, and the error is small.

[0053] In one specific embodiment, a clamping portion is configured on the heating table 800, and a clamping groove is formed by the collector 720 being axially recessed inward. The cooperation between the collector 720 and the heating table 800 is realized through the clamping action between the clamping portion and the clamping groove.

[0054] It should be noted that the content of lunar soil carried in one collector 720 is only 200 ± 20 mg, which is very small. Therefore, when the lunar soil in the collector 720 leaks from the loading cavity during transportation, it has a greater impact on the accuracy of the experimental results. And through this compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism, this situation can be avoided as much as possible, making the difference in the content of lunar soil in each collector 720 smaller, the accuracy of the experimental results higher, and the error smaller.

[0055] It should be noted that this compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism can also be used for transporting and analyzing soil samples on other celestial bodies, such as Venus, Mars, etc. There is no limitation in this regard. This solution is only described by taking the lunar soil on the moon as an example.

[0056] The following specifically describes the structure of the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism. Please refer to Figures 2 - 8 , Figure 2 shows Figure 1 a schematic diagram of the cover plate 400 in a closed state after the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 3 shows Figure 2 a cross - sectional view of the A - A section shown in Figure 4 shows Figure 3 a partial enlarged view of the B position shown in

[0057] Figure 5 shows Figure 1 a schematic diagram of the assembly of the feeding seat 100, the detection component 200, and the spring - back component 300 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 6 shows Figure 5 a top view of the assembly of the feeding seat 100, the detection component 200, and the spring - back component 300 in the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism shown in Figure 7 shows Figure 6 a cross - sectional view of the C - C section shown in Figure 8 shows Figure 6 a cross - sectional view of the D - D section shown in

[0058] Please refer to Figures 5 - 7 , Figures 9 - 11 and Figures 13 - 14The flexible docking guided lunar soil encapsulation sample delivery and detection mechanism provided by an embodiment of the present invention also includes a controller and a detection component 200 electrically connected to the controller, and the controller (not shown in the figure) is electrically connected to the sample delivery tube 700; the detection component 200 is installed on the feeding seat 100, and when the sample delivery tube 700 approaches and moves to the first preset position relative to the feeding seat 100, the detection component 200 can detect the sample delivery tube 700 and send a first electrical signal to the controller, so that the controller controls the sample delivery tube 700 to perform a sample discharging operation. When the sample delivery tube 700 moves closer to the feeding seat 100 and moves to the first preset position, the detection component 200 can detect that the sample delivery tube 700 is in the first preset position, and then send a first electrical signal to the controller. After obtaining the first electrical signal, the controller controls the sample delivery tube 700 to perform a sample discharging operation, so that the collector 720 is separated from the sample delivery tube 700, and then passes through the feeding seat 100 to cooperate with the heating platform 800.

[0059] Please continue reading Figures 5 - 7 , Figures 9 - 11 and Figure 13 The number of the detection components 200 provided in one embodiment of the present invention is two, and the two detection components 200 are arranged opposite to each other along the radial direction of the feeding seat 100. Since two detection components 200 are provided, when one of the detection components 200 fails, the other detection component 200 can work and send the first electrical signal to the controller, so that the fault tolerance rate of the device is high, especially when conducting experiments on the moon where it is difficult to replace parts, it can be more convenient and save trouble.

[0060] See also Figures 5 - 7 ,and Figures 13 - 14 , the detection assembly 200 of the flexible docking guided lunar soil package sample delivery and detection mechanism provided by an embodiment of the present invention includes a first mounting seat 210, a first sensor 220 and a detection plate 230; the first mounting seat 210 is fixedly connected to the frame 600, the first sensor 220 is fixedly connected to the first mounting seat 210 and electrically connected to the controller, the detection plate 230 is slidably connected to the first mounting seat 210, and the detection plate 230 can at least partially extend into the feeding cavity 110; when the sample delivery tube 700 moves to the first preset position relative to the feeding seat 100, the sample delivery tube 700 can abut against the detection plate 230 and drive the detection plate 230 to slide relative to the first mounting seat 210, so that the detection plate 230 abuts against the first sensor 220; when the detection plate 230 abuts against the first sensor 220, the first sensor 220 can send a first electrical signal to the controller, so that the controller controls the sample delivery tube 700 to perform a sample spitting operation.

[0061] When the sample delivery tube 700 moves relative to the feeding seat 100 to the first preset position, the sample delivery tube 700 abuts against the detection plate 230 extending into the feeding cavity 110 and drives the entire detection plate 230 to slide relative to the first mounting seat 210, so that the detection plate 230 can abut against the first sensing member 220, and further enables the first sensing member 220 to send a first electrical signal to the controller.

[0062] Please refer to Figure 7 , the detection plate 230 of the compliant docking and guiding type lunar soil encapsulation sample delivery-detection mechanism provided by an embodiment of the present invention includes a first detection arm 231 and a second detection arm 232 arranged at an angle; the first detection arm 231 is movably sleeved on the second detection arm 232, and at least a part of the first detection arm 231 extends into the feeding seat 100; the second detection arm 232 passes through the first mounting seat 210 and is slidably connected to the first mounting seat 210; when the sample delivery tube 700 moves relative to the feeding seat 100 to the first preset position, the sample delivery tube 700 can abut against the first detection arm 231 and drive the first detection arm 231 and the second detection arm 232 to move along the axial direction of the feeding seat 100, so that the second detection arm 232 abuts against the first sensing member 220. Specifically, the axial direction of the feeding seat 100 is Figure 7 the yy' direction in

[0063] Since the detection plate 230 includes the first detection arm 231 and the second detection arm 232 arranged at an angle, when the sample delivery tube 700 moves to the first preset position, the sample delivery tube 700 abuts against the first detection arm 231 and drives the first detection arm 231 to move along the axial direction of the feeding seat 100, and the second detection arm 232 moves synchronously under the drive of the first detection arm 231, so that the second detection arm 232 abuts against the first sensing member 220. At the same time, since the first detection arm 231 is movably sleeved on the second detection arm 232, when the first detection arm 231 drives the second detection arm 232 to move along the axial direction of the mounting seat, there is a certain margin of movement. Compared with the detection plate 230 formed by fixedly connecting the first detection arm 231 and the second detection arm 232, the entire detection plate 230 is not easily broken and has a longer service life.

[0064] In one of the embodiments, a second sensing member 240 is directly formed on the second detection arm 232. When the second sensing member 240 abuts against the first sensing member 220, the first sensing member 220 can send a first electrical signal to the controller. In another embodiment, the first sensing member 220 is a gravity sensing member. When the second detection arm 232 directly abuts against the first sensing member 220, the first sensing member 220 can send a first electrical signal to the controller.

[0065] Please refer to Figure 7 and Figure 14, in an embodiment of the present invention, the second detection arm 232 of the compliant docking and guiding lunar soil encapsulation sample delivery-detection mechanism includes a first stepped portion 2321, a second stepped portion 2322, and a third stepped portion 2323 that are connected in sequence; and the diameters of the first stepped portion 2321 and the third stepped portion 2323 are greater than the diameter of the second stepped portion 2322; a stepped hole 211 is formed in the first mounting seat 210, at least a part of the second stepped portion 2322 is accommodated in the stepped hole 211, and the first detection arm 231 is movably sleeved on the second stepped portion 2322 and can abut against the first stepped portion 2321; the detection assembly 200 further includes a first elastic member 250 sleeved on the outer periphery of the second stepped portion 2322, and the first elastic member 250 is in a compressed state and abuts between the third stepped portion 2323 and the stepped wall of the stepped hole 211.

[0066] By arranging the first elastic member 250 in a compressed state between the third stepped portion 2323 and the stepped wall of the stepped hole 211, the first elastic member 250 can apply an elastic force to the third stepped portion 2323 on the side away from the first detection arm 231 relative to the mounting seat, so that when the sample delivery tube 700 is not in the first preset position, the third stepped portion 2323 and the first sensing member 220 are in a separated state.

[0067] It should be noted that the first detection arm 231 is movably sleeved on the second stepped portion. When the sample delivery tube 700 is in the first preset position, at this time, the sample delivery tube 700 drives the first detection arm 231 along the axial direction of the feeding seat 100 and from Figure 7 y to y' in, so that the first detection arm 231 abuts against the first stepped portion 2321. At this time, through the lever principle, the first detection arm 231 drives the entire second detection arm 232 to overcome the elastic force of the first elastic member 250 and move along the axial direction of the feeding seat 100 from Figure 7 y to y' in, and finally makes the second sensing member 240 mounted on the third stepped portion 2323 abut against the first sensing member 220, so as to realize the first sensing member 220 sending a first electrical signal to the controller.

[0068] It should be noted that the second sensing member 240 can be directly integrally processed and formed on the third stepped portion 2323, or fixedly connected to the third stepped portion 2323, and no special limitation is made thereto.

[0069] Please refer to Figure 5 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 12, in one embodiment of the present invention, the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism further includes at least two resilient components 300 that are oppositely arranged and connected to the frame 600; and at least two resilient components 300 are respectively arranged on the side of the feeding seat 100 away from the feeding cavity 110; the resilient component 300 abuts against the feeding seat 100 and can drive the feeding seat 100 to move radially along the feeding seat 100. By arranging two resilient components 300 to drive the feeding seat 100 to move radially along the feeding seat 100, when the sample delivery tube 700 extends into the feeding cavity 110, it can be more easily inserted. In one specific embodiment, in order to ensure good sealing, the clearance between the sample delivery tube 700 and the feeding cavity 110 in clearance fit is 5 mm. At this time, by driving the movement of the feeding seat 100 through the resilient component 300, it is convenient for the sample delivery tube 700 to extend into the feeding cavity 110.

[0070] Please refer to Figure 8 , in one embodiment of the present invention, the resilient component 300 of the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism includes a second mounting seat 310, a second elastic member 320, and a abutting member 330; the second mounting seat 310 is fixedly connected to the frame 600, one end of the second elastic member 320 is connected to the second mounting seat 310, the other end of the second elastic member 320 is connected to the abutting member 330, and the abutting member 330 is fixedly connected to the outer wall of the feeding seat 100 on the side away from the feeding cavity 110; the second elastic member 320 is in a compressed state, and the second elastic member 320 can drive the abutting member 330 to move radially along the feeding seat 100 to drive the feeding seat 100 to move radially along its own direction.

[0071] Through the elastic deformation ability of the second elastic member 320 itself, the abutting member 330 is driven to move radially along the feeding seat 100, so that the feeding seat 100 fixedly connected to the abutting member 330 moves radially along its own direction, facilitating the insertion of the sample delivery tube 700 into the feeding cavity 110.

[0072] It should be noted that the abutting member 330 and the feeding seat 100 can be integrally processed or separately processed and fixedly connected by means such as bolt connection or welding. There is no limitation on this, as long as the feeding seat 100 can move synchronously when the second elastic member 320 drives the abutting member 330 to move.

[0073] Please refer to Figure 8 , in one embodiment of the present invention, the resilient component 300 of the compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism further includes a first connecting column 340 and a second connecting column 350. The first connecting column 340 is fixedly connected to the second mounting seat 310, and the second connecting column 350 is fixedly connected to the abutting member 330. One end of the second elastic member 320 is connected to the first connecting column 340, and the other end of the second elastic member 320 is connected to the second connecting column 350.

[0074] Please refer to Figures 1 - 4 Figures 1 - 4 , a compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism provided by an embodiment of the present invention further includes a cover plate 400. The cover plate 400 is rotatably connected to the frame 600, and the cover plate 400 has a closed state and an open state relative to the feeding seat 100. In the closed state, the cover plate 400 covers the side of the feeding seat 100 away from the heating table 800 and is clamped with the feeding seat 100 to restrict the feeding seat 100 from moving radially along it. In the open state, one end of the sample delivery tube 700 can at least partially extend into the feeding cavity 110. When this compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism is transported from the Earth to the Moon and lands on the Moon, the cover plate 400 is in the closed state, so as to avoid large lunar dust from entering the feeding cavity 110 under the action of a large impact force during landing, reducing the contamination of the surface of the heating table 800. At the same time, in this state, it can also restrict the elastic component from driving the feeding seat 100 to shake, making the whole device more stable and not easily damaged.

[0075] Please refer to Figure 4 Figure 4 , in one specific embodiment, the cover plate 400 protrudes axially outward with a limiting portion 410. In the closed state, the limiting portion 410 can be clamped with the feeding seat 100, thereby restricting the feeding seat 100 from moving radially along it.

[0076] Please refer to Figure 5 、 Figure 7 and Figure 8 Figure 8 , a compliant docking and guiding lunar soil encapsulation sample delivery - detection mechanism provided by an embodiment of the present invention further includes an induction coil assembly 500. The induction coil assembly 500 is installed between the feeding seat 100 and the heating table 800 and is electrically connected to the controller. When the collector 720 passes through the induction coil assembly 500 and cooperates with the heating table 800, the induction coil assembly 500 can send a second electrical signal to the controller, so that the controller controls the heating table 800 to rotate and rise to a second preset position.

[0077] By setting the induction coil assembly 500, when the collector 720 passes through the induction coil assembly 500, the induction coil assembly 500 can send a second electrical signal to the controller. Then, after the collector 720 cooperates with the heating table 800, the controller controls the heating table 800 to rotate and rise to a second preset position, so that the heating table 800 and the collector 720 can be covered by the cavity wall of the heating furnace and form a sealed heating space. At this point, the lunar soil in the collector 720 is heated to study the volatile components of the lunar soil.

[0078] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0079] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
