Description

Technical Field

[0001] The present invention relates to the technical field of lunar drill sample observation equipment, and in particular to a device for microscopic operation and observation of lunar drill samples. Background Art

[0002] my country's lunar exploration program has already collected and returned samples from the lunar surface. These samples, collected by drilling and scooping, have spent millions to billions of years in the vacuum environment of the lunar surface or near the lunar surface before being collected. Upon their return to Earth, these samples are at risk of contamination from two main sources.

[0003] First, dust contaminants in the air are a major source of contamination for lunar samples. An average room typically contains 100,000 particles of various types per cubic foot of air. While coarser particles can be effectively filtered and removed, finer particles are difficult to eliminate. The Moon and Earth contain the same chemical elements, albeit in different proportions. Some elements common on Earth are extremely rare on the Moon. Therefore, even a tiny particle can significantly affect the measured values of elements in lunar samples, leading to misleading research and erroneous conclusions. Second, if these lunar samples were exposed to Earth's humid air, they would react with water and oxygen. Iron in the samples would react with oxygen in the air to form rust, while minerals and glass in the samples would react with water in the air to form clay. Existing technology typically uses high-purity nitrogen isolation to protect lunar samples from airborne particulate matter, water, and oxygen.

[0004] In addition, for lunar drill samples, the geomorphological stratification structure of the samples contains a large amount of original lunar geographical information, which has important scientific research significance. During ground research, it is necessary to ensure that the original stratification structure of the drilled samples is not destroyed.

[0005] Therefore, how to provide a device for microscopic observation of lunar drilling samples that can ensure a water-free and oxygen-free environment and facilitate continuous observation at any position has become a technical problem that needs to be urgently solved by technical personnel in this field.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As described in the background art, lunar samples are exposed to the humid air of the Earth, where they will react with water and oxygen. The iron in the samples will react with the oxygen in the air and rust, and the minerals and glass in the samples will react with the water in the air to form clay. The prior art generally uses high-purity nitrogen isolation and protection to prevent lunar samples from being contaminated by particulate matter, water, and oxygen in the air. In addition, the geomorphological layered structure of lunar drilled samples contains a large amount of original lunar geographical information, which is of great scientific significance. During ground-based research, it is necessary to ensure that the original layered structure of the drilled samples is not destroyed. Therefore, how to provide a device for microscopic observation of lunar drilled samples that can ensure a water-free and oxygen-free environment and facilitate continuous observation at any position has become a technical problem that needs to be solved urgently by those skilled in the art.

[0022] To solve the above problems, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The present invention provides a device for microscopic operation and observation of lunar drilled samples, comprising a lunar sample storage box 1, a longitudinal slide rail 2, a transverse slide rail 3, a microscope 4 and a support leg 6. Two longitudinal slide rails 2 are provided, and the two longitudinal slide rails 2 are fixedly connected to the top surface of the lunar sample storage box 1. One end of the transverse slide rail 3 is slidably connected to one longitudinal slide rail 2, and the other end is connected to the other longitudinal slide rail 2. The microscope 4 is slidably connected to the transverse slide rail 3. An operation port 5 is opened on the lunar sample storage box 1, and a fluororubber glove is installed on the operation port 5. A plurality of support legs 6 are provided, and all are installed on the bottom surface of the lunar sample storage box 1.

[0023] Specifically, the top and front surfaces of the lunar sample storage box 1 are installed with transparent glass plates for easy observation by users. The provision of two longitudinal slide rails 2 can make the transverse slide rail 3 more stable during the sliding process. When adjustments are needed to the lunar drilled samples, users can operate by wearing fluororubber gloves. During the operation, the interior of the lunar sample storage box 1 is completely sealed and will not affect its water-free and oxygen-free environment.

[0024] Preferably, a lifting platform 7 is installed inside the lunar sample storage box 1, and the lifting platform 7 is used to place lunar drilling samples.

[0025] Preferably, the lifting operating platform 7 includes: a placement platform 71, a telescopic rod 73, a base plate 74, a sleeve 75, a screw A76, a ball handle 77, a hollow tube 78 and a fixed tube 79. An O-shaped groove 72 is provided on the surface of the placement platform 71, and the lunar drilling samples are placed in the O-shaped groove 72. One end of the telescopic rod 73 is connected to the bottom of the placement platform 71, and the top of the base plate 74 is connected to the other end of the telescopic rod 73. One end of the sleeve 75 is connected to the bottom of the placement platform 71, one end of the screw A76 is connected to the sleeve 75, and the ball handle 77 is threadedly connected to the screw A76. The top of the hollow tube 78 is connected to the bottom of the ball handle 77, and the other end of the screw A76 is slidably sleeved in the hollow tube 78. One end of the fixed tube 79 is connected to the base plate 74, and the other end is slidably connected to the hollow tube 78.

[0026] Specifically, the user can adjust the height of the placement table 71 by wearing fluororubber gloves. The user only needs to turn the ball handle 77. The ball handle 77 will drive the hollow tube 78 to move and adjust the length of the screw rod A76 exposed to the outside, thereby achieving the purpose of raising and lowering the placement table 71. In the technical solution of the present invention, the user can adjust the height of the placement table 71 while observing the lunar drilling samples through the microscope 4. At the same time, a scale ruler is provided in the horizontal direction inside the O-groove 72, which can assist in identifying the sample stratification information during the observation operation.

[0027] Preferably, a cover mechanism 8 is detachably connected to the placement table 71 .

[0028] Preferably, the cover mechanism 8 includes: a polytetrafluoroethylene cover 82, a handle 83 and a butterfly lock 84. A cover positioning hole 81 is opened on the placement table 71. The polytetrafluoroethylene cover 82 is detachably connected to the placement table 71 through the cover positioning hole 81. The handle 83 is installed on the top of the polytetrafluoroethylene cover 82, and the butterfly lock 84 is installed on the polytetrafluoroethylene cover 82.

[0029] Specifically, when no observation is being carried out, the present invention also provides a polytetrafluoroethylene cover 82, which can be covered on the top of the placement table 71 and locked by a butterfly lock 84 to better protect the samples and avoid operational errors that may cause the layered information of the lunar drilled samples to be destroyed. When subsequent observation is required, it is only necessary to remove the butterfly lock 84 and then pull the handle 83 to remove the polytetrafluoroethylene cover 82. The removed polytetrafluoroethylene cover 82 does not need to be taken out of the lunar sample storage box 1, but can be directly placed on the inner bottom of the lunar sample storage box 1, without destroying the water and oxygen-free environment in the lunar sample storage box 1.

[0030] Preferably, a transverse slide rail locking mechanism 9 is installed on the transverse slide rail 3 .

[0031] Preferably, the transverse slide rail locking mechanism 9 includes: a fixed plate 91, a threaded connection block 92, a screw rod B93, an abutment block 94, a pressure plate shaft 95, a pressure plate 96, a roller 97, a spring A98 and a limit block 99, the fixed plate 91 is installed on the transverse slide rail 3, the threaded connection block 92 is installed on the fixed plate 91, the screw rod B93 is threadedly connected to the threaded connection block 92, the top of the abutment block 94 is rotatably connected to the screw rod B93, the pressure plate shaft 95 is installed on the fixed plate 91, the pressure plate 96 is rotatably connected to the pressure plate shaft 95, the roller 97 is rotatably connected to the pressure plate 96 and abuts against the abutment block 94, one end of the spring A98 is connected to the fixed plate 91, and the other end is connected to the pressure plate 96, the limit block 99 is installed on the fixed plate 91, and the top abuts against the abutment block 94.

[0032] Specifically, when locking the transverse slide rail 3, the technical solution in the present invention adopts the form of friction locking, which is achieved through the characteristics of the rubber material. The roller 97 involved in the solution can also be fixedly connected. It is only necessary to ensure that when the spring A98 is not stretched or compressed by external force, the distance between the roller 97 and the limit block 99 is less than the width of the abutment block 94, thereby ensuring that when the abutment block 94 is "inserted" downward between the roller 97 and the limit block 99, the pressure plate 96 will rotate, causing the rubber layer A910 to contact the longitudinal slide rail 2 to form friction. When the lock is released, the screw rod B93 reverses, and the pressure plate 96 will reset under the action of the elastic force of the spring A98. In order to ensure the stability of the lock, two sets of transverse slide rail locking mechanisms 9 can be set in another embodiment of the present invention, which are placed at both ends of the transverse slide rail 3 to lock it with two different longitudinal slide rails 2.

[0033] Preferably, the cross section of the abutment block 94 is a right-angled trapezoid, and the side where the hypotenuse is located abuts against the limit block 99 , and a rubber layer A910 is attached to the surface of the side of the pressure plate 96 close to the longitudinal slide rail 2 .

[0034] Specifically, the bevel has stronger sliding properties, and in the solution of the present invention, the bevel abuts against the limit block 99 and slides when locked, which can make the transverse slide rail locking mechanism 9 run more smoothly.

[0035] Preferably, a microscope locking mechanism 10 is installed on the microscope 4, and the microscope locking mechanism 10 includes: a microscope bracket 101, a screw rod C102, a fixing ring 103, a slider 104, a rotating plate 105, a connecting rod 106, a pressure block 107, a rubber layer B108 and a spring B109. The microscope 4 is detachably connected to the microscope bracket 101, the screw rod C102 is fixedly connected to the microscope bracket 101, and the fixing ring 103 is sleeved on the screw rod C10 2, the slider 104 is slidably connected to the screw rod C102, the rotating plate 105 is threadedly connected to the screw rod C102, one end of the connecting rod 106 is hinged to the slider 104, the pressure block 107 is hinged to the other end of the connecting rod 106, and a rubber layer B108 is attached to the surface of the pressure block 107 on the side close to the transverse slide rail 3. A spring B109 is sleeved on the screw rod C102, with one end abutting against the fixing ring 103 and the other end abutting against the slider 104.

[0036] Specifically, in the unlocked state, the rotating plate 105 is in a high position, and the pressure block 107 is completely separated from the surface of the transverse slide rail 3. When locking, as the rotating plate 105 moves downward, the pressure block 107 will fall on the surface of the transverse slide rail 3 and generate friction with it through the rubber layer B108 to achieve the locking effect.

[0037] Preferably, a camera 11 is also installed on the microscope stand 101 .

[0038] Specifically, in addition to microscopic observation, the present invention also provides a camera 11 to facilitate users to take photos and record key parts.
