Description

Technical Field

[0001] This invention relates to the field of spherical soil sample processing mechanisms, specifically a rotary lifting in-situ encapsulation and heating extraction device for spherical soil samples. Background Technology

[0002] Deep space exploration refers to human exploration activities on the Moon and beyond, or on celestial bodies and the space environment. As an important direction of human space activities and a crucial pathway for innovation in space science and technology, it is one of the key development priorities in the current and future space field. Deep space exploration not only reflects a nation's technological level but also its comprehensive national strength. Currently, my country's fourth phase of lunar exploration has successfully completed its first lunar soil sample return mission, making a significant contribution to reconstructing the lunar evolution history and scientific research. With continuous technological updates and iterations, the next phase of lunar exploration plans to conduct in-situ analysis of lunar soil samples.

[0003] The difference between in-situ lunar soil sample analysis and sampling missions is that in-situ analysis does not require bringing samples back to Earth; lunar soil samples can be extracted and analyzed directly in orbit. However, there is currently a lack of a lunar soil sample processing mechanism capable of collecting lunar soil from different depths and geographical locations, processing the in-orbit samples, extracting volatiles through heating, and accurately analyzing the composition and isotopic structure of the lunar soil. Summary of the Invention

[0004] To better accomplish the task of in-situ analysis and processing of lunar soil samples, this invention proposes a rotary lifting in-situ lunar soil sample encapsulation and heating extraction device. This device enables the in-situ collection of lunar soil at a constant volume and density, ensuring a fixed mass of collected lunar soil. It also performs functions such as receiving the encapsulated lunar soil sample, extracting volatiles through heating, and discarding the sample by inversion. The device has a simple structure, can continuously process lunar soil samples, and is highly reusable. The heating element utilizes electromagnetic induction heating, resulting in high heating speed and energy utilization efficiency.

[0005] This invention proposes a rotary-lift in-situ packaging and heating extraction device for lunar soil samples, specifically comprising an in-situ packaging device and a sample processing device. The in-situ packaging device is made of metal and is used for the fixed-volume and fixed-density collection of lunar soil samples.

The rotary lifting device receives the in-situ packaging device and transports it to the heating extraction device, where the heating extraction device heats the collected lunar soil sample to collect gases volatilized from the soil. The heating extraction device employs electromagnetic induction heating.

[0008] Furthermore, the plurality of sampling vanes are arc-shaped with a chamfered structure on the concave side, and the height of the plurality of sampling vanes gradually decreases from the outer edge of the sampler toward the center. During sampling, the plurality of sampling vanes rotate to enable the star soil in-situ encapsulation device to have a drilling function and to expel large star soil particles and agglomerate small star soil particles.

[0009] Furthermore, the rotary lifting device includes a motor, a docking guide structure, several limit switches, a lead screw, several positioning wheels, several guide rails, a tilting gear, a rack, a cantilever support, a frame, and a cantilever.

The motor is located above the frame and connected to the lead screw, driving the lead screw to rotate. The tilting gear is connected to the cantilever. The cantilever support cooperates with the lead screw, and the rotation of the lead screw drives the cantilever support, thereby driving the cantilever to rise and fall. The positioning wheels are evenly installed on the cantilever. The cantilever support is located on both the left and right sides; several guide rails are respectively installed on the left and right sides inside the frame and cooperate with several positioning wheels to constrain the cantilever's degree of freedom so that it can only move up and down; a rack is set behind several guide rails on the left side and installed on the frame, meshing with a reversing gear to control the rotation of the cantilever; a docking guide structure is set on the outer surface of the right side of the frame for docking the sampling tube; several limit switches are set on the outer surface of the left side of the frame, which provide feedback and limit the movement of the cantilever by detecting the position of the cantilever support, and are divided into sample heating position, sample docking position and sample tilting position.

[0010] Furthermore, the heating extraction device includes an outlet and an induction heating furnace. The induction heating furnace is installed on the front side of the frame and is used to heat the collected lunar soil sample. The outlet is installed above the frame and connected to the induction heating furnace, and is used to deliver the volatile gas obtained after processing the lunar soil sample to the analyzer for in-situ analysis.

[0011] Furthermore, the induction heating furnace includes a furnace support, a furnace chamber, a coil support, an induction coil, a furnace shell, and a sealing ring. The furnace chamber is installed inside the furnace shell; the coil support is installed between the furnace chamber and the furnace shell; the induction coil is wound on the coil support for heating the interior of the induction heating furnace; the sealing ring is installed in an annular groove at the bottom of the furnace chamber; the sealing ring cooperates with the furnace support to form a sealed environment inside the furnace chamber; the furnace support, furnace chamber, coil support, and furnace shell are all made of ceramic material, and the coil support and furnace shell also serve to insulate the furnace body.

[0012] Furthermore, the sealing ring is provided with a sealing blade to enhance the sealing effect on the induction heating furnace.

[0013] Furthermore, the furnace trolley is mounted on a cantilever to receive the in-situ encapsulation device and move up and down with the cantilever.

[0014] Furthermore, the furnace drag center is provided with a ceramic cylindrical protrusion structure for positioning the star soil in-situ encapsulation device.

[0017] (2) The rotary lifting type lunar soil sample in-situ packaging and heating extraction device of the present invention has a simple structure. While the screw carries the furnace to move up and down, the furnace is connected to the rear flip gear through the rotating shaft. The flip gear cooperates with the rack to drive the furnace to flip up and down, so as to realize sample receiving, heating and pouring. It can continuously process lunar soil samples and has strong reusability.

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0028] Specific implementation method one: See Figure 1-5 This embodiment describes the rotary lifting in-situ sealing and heating extraction device for star soil samples. The device includes a star soil in-situ sealing device 24 and a sample processing device. The star soil in-situ sealing device 25 is made of metal and is responsible for the fixed-volume and fixed-density collection of star soil samples. The sample processing device includes a rotary lifting device and a heating extraction device. The rotary lifting device is connected to the heating extraction device, and the heating extraction device is located above the rotary lifting device. The rotary lifting device is responsible for transporting the star soil in-situ sealing device 24 to the heating extraction device. The heating extraction device heats the collected star soil sample to collect gases volatilized from the soil. The heating extraction device uses electromagnetic induction heating.

[0029] The in-situ encapsulation device 24 is designed in a circular cylindrical shape, including an encapsulation cover 1, a sampler 2, and a fixing structure. The outer sides of the encapsulation cover 1 and the sampler 2 are provided with protruding ridge structures. The fixing structure is a fixing pin 3, which passes through the protruding ridge structure to connect the encapsulation cover 1 and the sampler 2 together.

[0030] The sampler 2 is provided with several circular through holes 2-1 and several sampling vanes 2-2. The circular through holes 2-1 and several sampling vanes 2-2 are evenly distributed in a circumferential pattern at the bottom of the sampler 2. The circular through holes 2-1 and several sampling vanes 2-2 work together to allow the star soil to enter the sampler through compression, transportation and filling. The several sampling vanes 2-2 are arc-shaped and have a chamfered structure on the concave side. The height of the several sampling vanes 2-2 gradually decreases from the outer edge of the sampler to the center. During sampling, the several sampling vanes 2-2 rotate to enable the star soil in-situ sealing device 24 to have a drilling function, expelling large star soil particles and collecting small star soil particles.

[0031] The rotary lifting device includes a motor 4, a docking guide structure 7, several limit switches 9, a lead screw 10, several positioning wheels 11, several guide rails 12, a reversing gear 13, a rack 14, a cantilever support 21, a frame 22, and a cantilever 23. The lead screw 10, several positioning wheels 11, several guide rails 12, reversing gear 13, and rack 14 are installed inside the frame 22. The motor 4 is located above the frame 22 and connected to the lead screw 10, driving the lead screw 10 to rotate. The reversing gear 13 is connected to the cantilever 23 installed outside the frame 22. The cantilever support 21 cooperates with the lead screw 10, and the rotation of the lead screw 10 drives the cantilever support 21, which in turn drives the cantilever. 23 Lifting; the plurality of positioning wheels 11 are installed on the left and right sides of the cantilever bracket 21; the plurality of guide rails 12 are respectively installed on the left and right sides inside the frame 22 and cooperate with the plurality of positioning wheels 11 to constrain the degree of freedom of the cantilever 23 so that it can only move up and down; the rack 14 is set behind the plurality of guide rails 12 on the left side and is installed on the frame 22, and meshes with the flip gear 13 to control the rotation of the cantilever 23; the docking guide structure 7 is set on the outer surface of the right side of the frame 22 for docking the sampling tube; the plurality of limit switches 9 are set on the outer surface of the left side of the frame 22, and provide feedback and limit the movement position of the cantilever 23 by contacting the cantilever 23, which are divided into sample heating position, sample docking position and sample tilting position.

[0032] The heating extraction device includes an outlet 5 and an induction heating furnace 6: the induction heating furnace 6 is installed on the front side of the frame 22 and is used to heat the collected spherical soil sample; the outlet 5 is installed above the frame 22 and is connected to the induction heating furnace 6, so as to deliver the volatile gas obtained after the spherical soil sample is processed to the analyzer for analysis.

[0033] The induction heating furnace 6 includes a furnace support 8, a furnace chamber 15, a coil support 16, an induction coil 17, a furnace shell 18, and a sealing ring 19. The furnace chamber 15 is installed inside the furnace shell 18. The coil support 16 is installed between the furnace chamber 15 and the furnace shell 18. The induction coil 17 is wound around the coil support 16 for heating the interior of the induction heating furnace 6. The sealing ring 19 is installed in an annular groove at the bottom of the furnace chamber 15. The sealing ring 19 cooperates with the furnace support 8 to form a sealed environment inside the furnace chamber 15. The furnace support 8, the furnace chamber 15, the coil support 16, and the furnace shell 18 are made of ceramic material. The coil support 16 and the furnace shell 18 are also used for heat preservation of the furnace body.

[0034] The sealing ring 19 is provided with a sealing blade 20 to enhance the sealing effect on the induction heating furnace 6.

[0035] The furnace drag 8 is mounted on the cantilever 23 and is used to receive the star soil in-situ packaging device 24 and move up and down with the cantilever 23.

[0036] The furnace drag 8 has a ceramic cylindrical protrusion structure at its center, which is used to position the star soil in-situ encapsulation device 24.

[0037] The working principle of the rotary lifting type in-situ encapsulation and heating extraction device for star soil samples described in this invention is explained as follows:

[0038] During operation, the in-situ soil encapsulation device 24 is placed inside the sampling tube. The sampling tube, carrying the in-situ soil encapsulation device 24, is close to the surface of the sampling area. The sampling tube, through the convex structure of the in-situ soil encapsulation device 24, drives the device to rotate. The soil is collected at a constant volume and density through rotation and downward pressure. Rotation removes large surrounding soil particles, and the rotating discharge vanes 2-2 have a certain drilling function. The combination of downward pressure and rotation allows soil particles meeting the required size to enter the sampler 2. With a downward pressure in the range of 10N-20N and a rotation speed of 60rpm-90rpm, experiments show that soil will fill the encapsulation in about 1 minute, and can be completely filled in up to 3 minutes. This method has good soil collection results.

[0039] After the sampler is filled with star soil, the sampling tube is driven by the robotic arm into the docking guide structure 7 of the processing mechanism. During this movement, due to the particle chain effect, the star soil particles will not fall out of the circular through hole 2-1 at the bottom of the sampler 2. After the sampling tube passes through the docking guide structure 7, the star soil in-situ packaging device 24 is placed on the furnace drag 8. The furnace drag 8 has a ceramic cylindrical protrusion at its center for positioning the star soil in-situ packaging device 24. After the star soil in-situ packaging device 24 is in place, the sampling tube is pulled out of the docking guide structure 7 by the robotic arm.

[0040] After the in-situ encapsulation device 24 is installed and the sampling tube is removed, the motor 4 rotates and drives the lead screw 10. The lead screw 10 is threadedly engaged with the cantilever bracket 21. The rotation of the lead screw 10 drives the cantilever bracket 21 to rise. The cantilever bracket 21 drives the cantilever 23 and the tilting gear 13 to rise together via the shaft. During the rising process, the tilting gear 13 and the rack 14 move relative to each other under the trend of motion, thereby driving the shaft and the cantilever 23 to rotate counterclockwise, so that the furnace carriage 8, on which the in-situ encapsulation device 24 is installed, gradually docks with the induction heating furnace 6, and achieves sealing of the induction heating furnace 6 under the pressure brought by the rotation of the lead screw 10. During this movement, the cantilever bracket 21 can only move up and down under the constraint of the positioning wheel 11 and the guide rail 12. The position of the in-situ encapsulation device 24 is determined by the position detection of the cantilever bracket 21 by the upper limit switch 9. After determining that the in-situ encapsulation device 24 has reached the sample heating position, it is confirmed that the sample heating operation can be performed.

[0041] When the in-situ encapsulation device 24 is fed into the induction heating furnace 6, a high-frequency alternating current is passed through the induction coil 17. According to the law of electromagnetic induction, eddy currents are generated on the surface of the in-situ encapsulation device 24. Under the action of Joule heating, the encapsulated in-situ storable soil is heated. After being heated to a certain temperature, the storable soil sample will release volatile gas. The volatile gas leaves the in-situ encapsulation device 24 through the circular through hole 2-1 at the bottom of the sampler 2 and enters the analyzer through the gas outlet 5 above the induction heating furnace 6 for analysis.

[0042] After the star soil sample is heated and extracted, the motor 4 rotates in the reverse direction, causing the lead screw 10 to rotate in the reverse direction. The lead screw 10 drives the cantilever bracket 21, which in turn drives the cantilever 23 and the rotating gear 13 to move downwards via a shaft. The rotating gear 13 moves relative to the rack 14, which in turn drives the cantilever 23 and the furnace trailer 8 to rotate clockwise via a shaft. Until the furnace trailer 8 rotates to a position facing the ground, the star soil in-situ packaging device 24 on the furnace trailer 8 slides down under the influence of gravity, completing the star soil packaging and disposal process. At this time, the limit switch 9 below detects the position of the cantilever bracket 21 to determine that the cantilever 23 and the furnace trailer 8 have reached the sample tilting position, and determines that the sample tilting is complete.

[0043] After the tilting is completed, motor 4 drives lead screw 10 to rotate clockwise. Lead screw 10 drives cantilever bracket 21, tilting gear 13, cantilever 23, and furnace trailer 8 to rise. The tilting gear 13 and rack 14 move relative to each other, causing cantilever 23 and furnace trailer 8 to rotate counterclockwise. At this time, the middle limit switch 9 determines that cantilever 23 and furnace trailer 8 have returned to the sample docking position by detecting the position of cantilever bracket 21. Motor 4 stops operating. At this time, furnace trailer 8 is facing docking guide structure 7, and furnace trailer 8 waits to receive the next star soil in-situ packaging device 24.

[0044] In summary, the rotary lifting in-situ packaging and heating extraction device for star soil samples described in this application can eliminate large-particle star soil and collect small-particle star soil until the packaging device is full, thus achieving fixed-volume and fixed-density collection of star soil. The invention has a simple structure. While the lead screw 10 carries the furnace drag 8 up and down, the furnace drag 8 is connected to the rear rotating gear 13 via a rotating shaft. The rotating gear 13 cooperates with the rack 14 to drive the furnace drag 8 to rotate up and down, realizing the receiving, heating, and pouring of the sample. It can continuously heat and process several collected star soil samples, exhibiting strong reusability. Furthermore, the rotary lifting in-situ packaging and heating extraction device for star soil samples uses electromagnetic induction heating. Through the alternating magnetic field generated by the induction coil, an alternating current, i.e., eddy current, is generated inside the star soil in-situ packaging device 24, thereby heating the sample. This method has a fast heating speed and high energy utilization rate.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the invention.
