Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lunar sample collection, and in particular to a stacked extraction type sticking device for lunar dust collection. BACKGROUND

[0002] Lunar dust is a fine component in lunar regolith, and lunar soil particles with a particle size of less than 1 mm are generally referred to as lunar dust. The median particle size of a representative sample of lunar dust is between 40 μm and 130 μm, and the average particle size is 70 μm, of which particles smaller than 20 μm account for 10% to 20% by weight. Lunar dust is a non-cemented particulate material produced by repeated meteorite impacts during the formation of the moon and the action of solar wind and cosmic rays, and is mainly composed of crystalline particles, larger igneous rock fragments, exsolved particles and microparticle metal particles. Lunar dust has unique chemical composition, spectrum, magnetism, electricity and micro-mechanical properties, and is an important sample for studying the interaction process between lunar surface material and space environment. At the same time, it also has important research value for ensuring the safety of astronauts and lunar activity organizations. However, the current research on lunar dust samples has limitations, and lacks detailed analysis of the physical and chemical properties of lunar dust and its causes, which limits the understanding of the formation mechanism of lunar dust, the law of natural / human dust raising on the moon, and the mechanism of dust migration on the moon.

[0003] The acquisition of lunar dust samples will provide important samples for clarifying the formation mechanism and microscopic products of lunar dust, determining the physical and chemical properties of lunar dust and its causes, and revealing the dust raising mechanism and dust migration law on the lunar surface, and has important research significance.

The independent adhesive unit is operated by pulling / pulling motion to collect lunar dust independently and automatically ejects a new adhesive sheet to the working position.

[0027] Specifically, as shown in Figure 1 , Figure 3 and Figure 6 , the protective shell 1 of the embodiment adopts a rectangular structure, the protective shell 1 has a first side wall 11, a second side wall 12, a third side wall 13 and a fourth side wall 14, the first side wall 11 and the third side wall 13 are correspondingly arranged and correspond to the long sides of the rectangular structure, the second side wall 12 and the fourth side wall 14 are correspondingly arranged and correspond to the short sides of the rectangular structure, the bottom of the first side wall 11 and the third side wall 13 forms a retracted edge 16, and the bottom of the second side wall 12 and the fourth side wall 14 is higher than the first side wall 11 and the third side wall 13 by at least the thickness of one extractable adhesive sheet 2 to form the pull-out port, so as to facilitate the extraction of the extractable adhesive sheet 2 at the bottom.

[0028] Further, as shown in Figure 2 , Figures 4-6 , a preferred scheme of the embodiment is that one side surface of the retracted edge 16 for overlapping the extractable adhesive sheet 2 is a bevel surface, the cross section of the extractable adhesive sheet 2 is in a basin type structure, the two side walls of the basin type structure are overlapping side walls 23, and the outer surfaces of the overlapping side walls 23 are respectively adapted to be overlapped on the two retracted edges 16.

[0036] In the present embodiment, the pull handle 21 located at the bottom is of a straight line type and is located at the middle of the side of the extractable adhesive patch 2, and the remaining pull handles 21 are all of an L-shaped structure, and the operation ends of the two adjacent L-shaped pull handles are respectively located on the two sides of the straight line type pull handle. The pull handles of different shapes and arrangements in the present embodiment can provide sufficient operation intervals for astronauts.

[0037] Embodiment 3 On the basis of Embodiment 1 or Embodiment 2, the present embodiment provides a preferred structure of the ejection mechanism, as shown in Figure 3 , Figure 5 and Figure 6 , the ejection mechanism in the present embodiment comprises a plurality of sleeve assemblies 3, each of which comprises an outer sleeve 31, a spring 33 and an inner sleeve 32. A plurality of ejection holes are formed in the top wall of the protective shell 1, and each of the ejection holes is fixed with an outer sleeve 31. The inner sleeve 32 is movably arranged in the outer sleeve 31, and the spring 33 is located in the inner sleeve 32 and connected to the top wall of the outer sleeve 31 and the bottom wall of the inner sleeve 32 at both ends. The bottom wall of the inner sleeve 32 is extended into the protective shell 1 from the corresponding ejection hole under the action of the spring 33 and elastically presses the plurality of extractable adhesive patches 2. The plurality of sleeve assemblies can exert a stable ejection force on the extractable adhesive patches. Preferably, as shown in Figure 5 and Figure 6 , the ejection mechanism in the present embodiment further comprises a flat frame 34, and the bottom walls of the plurality of inner sleeves 32 are fixedly connected to the flat frame 34, and the flat frame 34 elastically abuts against the topmost extractable adhesive patch 2. The flat frame is arranged to facilitate the stable downward movement of the plurality of inner sleeves and exert a stable and uniform ejection force on the extractable adhesive patches.

[0038] Furthermore, such as Figure 5 As shown, multiple sets of sleeve assemblies 3 are arranged in a rectangular structure. Specifically, four sets of sleeve assemblies 3 can be used. The flat plate frame 34 is a rectangular frame, and one sleeve assembly 3 is installed at each corner of the flat plate frame 34 to facilitate smooth ejection. Each of the four corners of the flat plate frame 34 is provided with a limiting protrusion ring 35, which can abut and limit the bottom of the inner sleeve 32 of the corresponding sleeve assembly 3 within the corresponding limiting protrusion ring 35. The bottom of the inner sleeve 32 can be fixed to the flat plate frame 34 or not, and the clamping and limiting with the flat plate frame 34 can be achieved by the force of the spring 33.

The outer peripheral sidewall of the inner sleeve 32 slides against the inner sidewall of the outer sleeve 31, and the inner sleeve 32 can move axially relative to the outer sleeve 31, while the spring 33 is always in a compressed state.

[0040] In this embodiment, a stacked, extractable adhesive device for collecting lunar dust is used as follows: During operation, the inner sleeves are pressed downwards by springs. Multiple inner sleeves work together to press the flat frame downwards onto the tops of multiple extractable adhesive pads. These pads abut against the closed edge of the overlapping sidewall. The bottommost extractable adhesive pad is positioned corresponding to the pull-out opening (i.e., the working position), but it will not detach from the adhesive opening due to the limiting effect of the closed edge. The entire stacked, extractable adhesive device is placed on the lunar surface. The bottommost extractable adhesive pad collects lunar dust. After collecting the dust, the extracted adhesive pad is pulled out and placed into an individually numbered packaging container for return. The extracted adhesive pads stacked on top are pushed to the working position to continue collecting lunar dust at the next sampling point.
