Description

Technical Field

[0001] This invention relates to the field of lunar sample collection technology, specifically to an array-type extraction and adhesion device for collecting lunar dust. Background Technology

[0002] Lunar dust is a fine component of lunar regolith, generally referring to lunar regolith particles with a diameter less than 1 mm. Representative lunar dust samples have a median particle size between 40 μm and 130 μm, with an average particle size of 70 μm. Particles smaller than 20 μm account for 10%–20% of the weight. Lunar dust is unbonded particulate matter produced during the Moon's formation process by repeated impacts from meteorites, solar wind, and cosmic rays. It mainly consists of crystalline grains, larger igneous rock fragments, exfoliated debris, and microscopic metallic particles. Lunar dust possesses unique chemical composition, spectral, magnetic, electrical, and micromechanical properties, making it an important sample for studying the interaction between lunar surface materials and the space environment. It also holds significant research value for ensuring the safety of astronauts and operational agencies on the lunar surface. However, current research on lunar dust samples has limitations, lacking detailed analysis of its physicochemical properties and formation processes, which restricts a deeper understanding of lunar dust formation mechanisms, natural / anthropogenic dust emission patterns on the lunar surface, and lunar dust migration mechanisms.

[0003] Obtaining lunar dust samples will provide important samples for clarifying the formation mechanism and microscopic products of lunar dust, determining the physicochemical properties and causes of lunar dust, and revealing the mechanism of lunar dust emission and the laws of dust migration and movement. It has important research significance and is also of great engineering significance for ensuring the safety of astronauts and lunar surface activities.

[0004] Currently, there are no dedicated collection devices on the market for collecting lunar dust samples. Mechanisms designed for other purposes are often incompatible with the requirements of independence, contamination resistance, human-machine interface operability, and safety in lunar sample collection, and therefore cannot meet the actual needs of collecting lunar dust samples. Some lunar dust sample collection solutions require carrying multiple 500g box-shaped devices for collection, but these solutions cannot meet the needs of collecting multiple samples at different locations with relatively small weights. Summary of the Invention

[0005] In order to solve one or more technical problems existing in the prior art, the present invention provides an array-type extraction and adhesion device for collecting lunar dust.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: The present invention provides an array-type extraction and adhesion device for collecting lunar dust, including a mounting bracket, multiple adhesion plate brackets and multiple adhesion plate assemblies. The mounting bracket has multiple connecting claws, and a horizontally arranged adhesion plate bracket is fixed below the free end of each connecting claw. The multiple adhesion plate brackets are located at the same horizontal height, and an operating interval is reserved between two adjacent adhesion plate brackets. An adhesion plate assembly is horizontally pulled out and connected to the bottom of each adhesion plate bracket. An auxiliary connector is installed at the upper center position of the mounting bracket.

[0007] The beneficial effects of the present invention are: the array-type extraction and adhesion device for lunar dust collection of the present invention, by setting multiple array-arranged pull-out adhesion plate components, allows the opening and closing of a single adhesion plate component to complete the lunar dust adhesion, and enables multiple independent collection of lunar dust particle samples at multiple points.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the end of the adhesive plate bracket near the auxiliary connector is a limiting end, and the end away from the auxiliary connector is a locking end. The two opposite ends of the adhesive plate assembly are an abutting end and a locking end, respectively. A pull-out groove is formed at the bottom of the adhesive plate bracket, extending from the limiting end to the locking end. The limiting end has a limiting baffle that limits the abutting end of the adhesive plate assembly, and the locking end is equipped with a locking component that blocks and locks the locking end of the adhesive plate assembly.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting a pull-out groove, a limiting baffle and a locking component, when the adhesive plate assembly is inserted into the pull-out groove, both ends of the adhesive plate assembly can be blocked and locked to prevent the adhesive plate assembly from falling off the adhesive plate bracket.

[0011] Furthermore, the locking assembly includes a locking housing, a drive pin, and a locking lock cylinder. The locking housing is fixed to the upper side of the locking end of the adhesive plate bracket. The bottom of the locking housing has a lock cylinder outlet. The side wall of the locking housing opposite to the adhesive plate bracket has a horizontal operating port. The locking lock cylinder is mounted in the locking housing and can move up and down. The locking lock cylinder has a drive hole. The drive hole is arranged at an angle. The drive pin passes through the horizontal operating port and the drive hole in sequence and is limited in the locking housing. The drive pin moves horizontally along the horizontal operating port and drives the locking lock cylinder to move up and down through the drive hole. The lower end of the locking lock cylinder can extend from the lock cylinder outlet and abut against the locking end face of the adhesive plate assembly to block and lock.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting up a locking housing, a drive pin, and a locking cylinder, the locking cylinder can be driven to move up and down by operating the drive pin to move horizontally, thereby using the drive hole to achieve blocking and locking of the end face of the adhesive plate assembly.

[0013] Furthermore, a limiting plate is fixed in the middle of the drive pin to prevent the drive pin from dislodging from the horizontal operating port. The limiting plate is located between the locking cylinder and the locking housing. One end of the drive pin is movably inserted into the drive hole, and the other end of the drive pin is located outside the locking housing and connected to an operating handle.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting a limit plate, the drive pin can be prevented from coming out of the horizontal operating port.

[0015] Furthermore, the lower end of the locking cylinder is inclined on the side opposite to the adhesive plate bracket, and the lower end of the locking cylinder is located inside the lock cylinder outlet.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting the lower end of the locking cylinder as an inclined surface and extending the lower end of the locking cylinder into the lock cylinder outlet, the locking cylinder can smoothly enter and exit the lock cylinder outlet.

[0017] Furthermore, there are two limiting baffles, which are respectively located on both sides of the abutting end of the adhesive plate assembly, and a channel for accommodating the abutting end of the adhesive plate assembly is formed between the two limiting baffles.

[0018] The advantage of adopting the above-mentioned further solution is that the locking part of the adhesive plate assembly can be accommodated in the channel.

[0019] Furthermore, the adhesive plate assembly includes an upper cover plate, a lower cover plate, and a locking part. The locking part is installed at the other end of the lower cover plate. One end of the upper cover plate and the lower cover plate are hinged together. The other end of the upper cover plate is locked to the other end of the lower cover plate through the locking part. A velvet fixing part is installed on the inner side of the upper cover plate, and an adhesive velvet is installed on the velvet fixing part. The end where the upper cover plate and the lower cover plate are hinged together is the locking end, and the end where the upper cover plate and the lower cover plate are locked together is the abutting end.

[0020] Furthermore, the upper cover plate has a push-out cavity on one side relative to the lower cover plate. A guide post arranged perpendicularly to the upper cover plate is installed in the push-out cavity. A slider, a first connecting rod, and a second connecting rod are installed in the push-out cavity. The slider is slidably engaged with the guide post. The slider has two inclined push-out holes. One end of the lower cover plate is hinged to one end of the upper cover plate via a hinge shaft. One end of the first connecting rod is hinged to one end of the lower cover plate via a connecting shaft. The other end of the first connecting rod is hinged to one end of the second connecting rod via a first sliding shaft. The other end of the second connecting rod has a second sliding shaft. The first and second sliding shafts are slidably disposed in the two push-out holes, respectively. The connecting shaft, hinge shaft, first sliding shaft, and second sliding shaft are all arranged in parallel. A velvet fixing part for attaching and adhering velvet is installed on the end of the slider away from the upper cover plate. During the opening of the lower cover plate relative to the upper cover plate, one end of the lower cover plate can pull the first and second connecting rods to move, causing the first and second sliding shafts to move along the push-out holes, thereby driving the velvet fixing part to extend out of the push-out cavity along the guide post.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by setting a scissor-type ejection mechanism, the velvet fixing part can be ejected when the lower cover is opened.

[0022] Furthermore, the auxiliary connector of the mounting bracket has multiple connecting claws on both sides, and the multiple connecting claws on one side of the auxiliary connector and the multiple connecting claws on the other side are arranged side by side in sequence along the first direction.

[0023] Furthermore, both the adhesive plate bracket and the adhesive plate assembly are rectangular structures, with the short side of the adhesive plate bracket extending along the first direction; among the multiple adhesive plate brackets on the same side of the auxiliary connector, the long sides of two adjacent adhesive plate brackets are arranged close together.

[0045] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0046] Example 1

[0047] like Figures 1-16 As shown, this embodiment of an array-type adhesive collection device for lunar dust includes a mounting bracket 100, multiple adhesive plate supports 200, and multiple adhesive plate assemblies. The mounting bracket 100 has multiple connecting claws 102, and a horizontally arranged adhesive plate support 200 is fixed below the free end of each connecting claw 102. The multiple adhesive plate supports 200 are located at the same horizontal height, and an operating interval is reserved between adjacent adhesive plate supports 200. An adhesive plate assembly is horizontally pulled out to the bottom of each adhesive plate support 200. An auxiliary connector 101 is installed at the upper center of the mounting bracket 100. Specifically, the middle part of the mounting bracket 100 is a central fixing part 103, and the auxiliary connector 101 can be installed on the upper side of the central fixing part 103. The auxiliary connector 101 can be a quick-release connector commonly used in the aerospace field, and the central fixing part 103 can be a plate-shaped or block-shaped structure. The connecting claws 102 can be arc-shaped.

[0048] like Figures 1-4 As shown, in a preferred embodiment, the auxiliary connector 101 of the mounting bracket 100 has multiple connecting claws 102 on each side, and the multiple connecting claws 102 on one side of the auxiliary connector 101 and the multiple connecting claws 102 on the other side are arranged side by side in sequence along the first direction.

[0049] like Figures 1-4As shown, in a preferred embodiment, both the adhesive plate holder 200 and the adhesive plate assembly are rectangular structures, with the short side of the adhesive plate holder 200 extending along the first direction; among the multiple adhesive plate holders 200 on the same side of the auxiliary connector 101, the long sides of adjacent adhesive plate holders 200 are arranged adjacent to each other. Preferably, this device design supports array-type (m×n) arrangements, such as 3×2 or 4×2, which can realize multiple independent collections of lunar dust samples at multiple points in a high-vacuum lunar environment.

[0050] This embodiment describes an array-type extraction and adhesion device for collecting lunar dust. By setting up multiple array-arranged pull-out adhesion plate assemblies, the opening and closing of a single adhesion plate assembly can be operated to complete the lunar dust adhesion, enabling multiple and independent collection of lunar dust particle samples at multiple points.

[0051] Example 2

[0052] Based on Embodiment 1, this embodiment provides a preferred assembly scheme for the adhesive plate bracket 200 and the adhesive plate assembly. For example... Figures 1-6 As shown, in this embodiment, the adhesive plate bracket 200 has a limiting end 201 near the auxiliary connector 101 and a locking end 203 away from the auxiliary connector 101. The two opposite ends of the adhesive plate assembly are an abutment end 301 and a locking end 302, respectively. A pull-out groove 204 extending from the limiting end 201 to the locking end 203 is formed at the bottom of the adhesive plate bracket 200. The limiting end 201 has a limiting baffle 205 that limits the abutment end 301 of the adhesive plate assembly. The locking end 203 is equipped with a locking component 400 that blocks and locks the locking end 302 of the adhesive plate assembly. By providing the pull-out groove, the limiting baffle, and the locking component, when the adhesive plate assembly is inserted into the pull-out groove, both ends of the adhesive plate assembly can be blocked and locked, preventing the adhesive plate assembly from detaching from the adhesive plate bracket.

[0053] like Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, there are two limiting baffles 205, which are respectively located on both sides of the abutment end 301 of the adhesive plate assembly. A channel for accommodating the abutment end 301 of the adhesive plate assembly is formed between the two limiting baffles 205. The locking part of the adhesive plate assembly can be accommodated in the channel.

[0054] A preferred embodiment of this solution is as follows: Figures 12-16As shown, the adhesive plate assembly in this embodiment includes an upper cover plate 303, a lower cover plate 304, and a locking part 305. The locking part 305 is installed at the other end of the lower cover plate 304. One end of the upper cover plate 303 and the lower cover plate 304 are hinged together, and the other end of the upper cover plate 304 is locked to the other end of the lower cover plate 304 by the locking part 305. A velvet fixing part 306 is installed on the inner side of the upper cover plate 303, and a velvet adhesive is installed on the velvet fixing part 306. The end where the upper cover plate 303 and the lower cover plate 304 are hinged together is the locking end 203, and the end where the upper cover plate 303 and the lower cover plate 304 are locked together is the abutment end 301. The hinge structure specifically adopts a hinge. The adhesive plate assembly adopts a rectangular structure as a whole. The short side of the adhesive plate assembly is used for hinge and locking, and the long side of the adhesive plate assembly is used for sliding engagement with the pull-out groove 204 of the adhesive plate bracket 200. All adhesive plate assemblies open outwards from the entire adhesive device when opened to avoid interference.

[0055] In this embodiment, the velvet fixing part 306 can be directly fixed inside the upper cover plate 303, or it can be installed inside the upper cover plate 303 using the scissor mechanism described below.

[0056] like Figure 15 and Figure 16As shown, in a preferred embodiment, the upper cover plate 303 has a push-out cavity on one side opposite to the lower cover plate 304. A guide post 316, arranged perpendicularly to the upper cover plate 303, is installed in the push-out cavity. A slider 315, a first connecting rod 313, and a second connecting rod 314 are installed in the push-out cavity. The slider 315 slides with the guide post 316. The slider 315 has two inclined push-out holes 318. One end of the lower cover plate 304 is hinged to one end of the upper cover plate 303 via a hinge shaft 317. One end of the first connecting rod 313 is hinged to one end of the lower cover plate 304 via a connecting shaft 312. The other end of the first connecting rod 313 is connected to one end of the second connecting rod 314 via a first sliding shaft 319. The second connecting rod 314 is hinged, and the other end of the second connecting rod 314 is provided with a second sliding shaft 320. The first sliding shaft 319 and the second sliding shaft 320 are respectively slidably disposed in two ejection holes 318. The connecting shaft 312, the hinge shaft 317, the first sliding shaft 319 and the second sliding shaft 320 are all arranged in parallel. The end of the slider 315 facing away from the upper cover plate 303 is equipped with a velvet fixing part 306 for installing the velvet cloth. When the lower cover plate 304 is opened relative to the upper cover plate 303, one end of the lower cover plate 304 can pull the first connecting rod 313 and the second connecting rod 314 to move, so that the first sliding shaft 319 and the second sliding shaft 320 move along the ejection hole 318, thereby driving the velvet fixing part 306 to extend out of the ejection cavity along the guide post 316. By setting a scissor-type ejection mechanism, the velvet fixing part can be ejected when the lower cover plate is opened, and after the velvet cloth has been used to attach the sample, it can be put back into the ejection cavity for sealed preservation. In this embodiment, the velvet fixing part can be a velvet fixing frame or a velvet fixing plate, as long as it can fix and stick the velvet.

[0057] The adhesive plate assembly in this embodiment can also adopt a structure commonly used in the aerospace field for adhering to lunar dust samples. The adhesive cloth can be installed in the cloth fixing part 306, which can be fixed to the side of the upper cover plate 303 near the lower cover plate 304. The aforementioned scissor mechanism can be installed inside the cloth fixing part 306. When the lower cover plate is opened, the scissor mechanism inside the cloth fixing part 306 can be driven to move synchronously, pushing the plate fixing the adhesive cloth towards the pre-collection direction. After the adhesion is completed, the lower cover plate 304 is fastened onto the upper cover plate 303, the locking assembly is unlocked, and the adhesive plate assembly can be removed and returned independently.

[0058] The adhesive cloth used has a micron-level microstructure (such as coil, brush, or braided shapes) and is made of materials such as polyetheretherketone (PEEK), polyimide (PI), and polyamide (PA), exhibiting adhesive properties. Material compatibility with the sample is considered; the surface material of components in contact with lunar dust needs to be selected based on the lowest possible contamination to extraterrestrial samples, or on surface treatment processes.

[0059] The locking part 305 in this embodiment adopts a press-fit elastic locking pin type locking structure, specifically including a locking shell 310, two locking buttons 309, and a spring. The locking shell 310 has a mounting through hole, in which the two locking buttons 309 can be slidably installed and arranged opposite each other. A spring is installed in the mounting through hole, and the two ends of the spring are respectively connected to the two locking buttons 309. Each of the two locking buttons 309 is connected to a locking pin 308 at one end inside the locking shell 310. The two locking pins 308 extend out of the locking shell 310 and face each other, and are arranged coaxially. The locking pins 308 are also arranged parallel to one side of the mounting through hole of the locking shell 310. By pressing the two locking buttons 309 relative to each other, the spring is compressed, and the two locking pins 308 can be retracted into the locking shell 310. When the two locking buttons 309 are released, the two locking pins 308 can extend out of the locking shell 310 to engage with the abutting end of the upper cover plate 303.

[0060] In this embodiment, two locking lugs 307 can be provided at one end of the velvet fixing part 306 or one end (abutting end) of the upper cover plate 303. When the lower cover plate 304 is flipped to be close to the upper cover plate 303, the two locking pins 308 of the locking part 305 can be respectively inserted into the two locking lugs 307 for locking. When it is necessary to open the upper cover plate 303 to pick up the moon dust sample, the two locking buttons 309 of the locking part 305 of the lower cover plate 304 can be pressed to drive the two locking pins 308 to retract into the locking housing 310 and contact the locking between the upper cover plate 303 and the lower cover plate 304.

[0061] The array extraction lunar dust collection device of this embodiment can complete the lunar dust collection by opening and closing a separate operating mechanism, and maintain the original state of lunar dust collection by sealing with a cover plate, so as to realize multiple independent collection of lunar dust particle samples at multiple locations.

[0062] Example 3

[0063] Based on Embodiment 2, this embodiment provides a preferred structure for the card slot assembly. For example... Figures 7-14As shown, the locking assembly in this embodiment includes a locking housing 401, a drive pin 402, and a locking lock cylinder 403. The locking housing 401 is fixed to the upper side of the locking end 203 of the adhesive plate bracket 200. A lock cylinder outlet 404 is provided at the bottom of the locking housing 401. A horizontal operating port 405 is provided on the side wall of the locking housing 401 opposite to the adhesive plate bracket 200. The locking lock cylinder 403 is movably mounted within the locking housing 401. A drive hole 406 is provided, which is arranged at an angle. A drive pin 402 passes through the horizontal operating port 405 and the drive hole 406 in sequence and is limited within the locking housing 401. The drive pin 402 moves horizontally along the horizontal operating port 405 and drives the locking cylinder 403 to move up and down through the drive hole 406. The lower end of the locking cylinder 403 can extend from the lock cylinder outlet 404 and abut against the locking end 302 end face of the adhesive plate assembly to block and lock. By setting up the locking housing, drive pin, and locking cylinder, the horizontal movement of the drive pin can be used to drive the locking cylinder to move up and down through the drive hole, thereby blocking and locking the locking end face of the adhesive plate assembly.

[0064] To facilitate the positioning of the drive pin 402 after it moves into position within the drive hole 406, a horizontal limiting segment 407 can be provided at both the upper and lower ends of the drive hole 406. When the drive pin 402 moves to the upper or lower end of the drive hole 406, it can be engaged with the corresponding horizontal limiting segment 407 for positioning, thus preventing the drive pin 402 from moving back and forth within the drive hole 406.

[0065] like Figure 9 and Figure 10 As shown, specifically, in this embodiment, a limiting plate 409 is fixed to the middle of the drive pin 402 to prevent the drive pin 402 from disengaging from the horizontal operating port 405. The limiting plate 409 is located between the locking cylinder 403 and the locking housing 401. By setting the limiting plate, the drive pin can be prevented from disengaging from the horizontal operating port.

[0066] like Figure 10 As shown, preferably, one end of the drive pin 402 is movably inserted into the drive hole 406, and the other end of the drive pin 402 is located outside the locking housing 401 and connected to an operating handle 408.

[0067] like Figure 4 , Figure 5 and Figure 7As shown, in a preferred embodiment, the lower end of the locking cylinder 403 has an inclined surface 410 on the side facing away from the adhesive plate bracket 200, and the lower end of the locking cylinder 403 is located inside the lock cylinder outlet 404. By setting the lower end of the locking cylinder as an inclined surface and allowing the lower end of the locking cylinder to extend into the lock cylinder outlet, the locking cylinder can smoothly enter and exit the lock cylinder outlet.

[0068] like Figure 12 As shown, in order to facilitate the locking and limiting of the locking cylinder 403 and the upper cover plate 303, a locking groove 311 can be opened at the locking end 302 of the upper cover plate 303, so that when the locking cylinder 403 moves downward, it can be locked into the locking groove 311 to realize the locking and limiting of the locking cylinder 403 and the upper cover plate 303. The locking groove 311 can serve as a limiting and blocking function in the pulling direction.
