Description

Technical Field

[0001] This invention relates to the field of deep space exploration technology, specifically to a lunar rock and rock powder storage device and sampling method for lunar resource exploration. Background Technology

[0002] In recent years, my country has made remarkable achievements in lunar exploration, especially in the significant breakthroughs achieved in lunar sample return missions. However, existing sample return missions still have certain limitations: firstly, the sample research cycle is long and the exploration range is limited; secondly, due to technological limitations, the collected samples are mainly lunar regolith, lacking rock samples less affected by impacts and space weathering, which greatly restricts a deeper understanding of lunar evolution. The lunar exploration program is actively underway, aiming to date, analyze the elemental composition and morphology of in-situ lunar rock samples, and select high-value rock samples for storage in a sample storage basket based on the analysis results.

[0003] Therefore, there is a need for a device that can meet the requirements of micro-quantitative analysis and store a certain amount of high-value rock samples. Summary of the Invention

[0004] To address the aforementioned lack of research on rock sample collection in lunar exploration, this invention proposes a lunar rock and rock powder storage device and sampling method for lunar resource exploration. This invention achieves efficient integration of rock block storage and temporary rock powder storage through a single motor drive, featuring a compact structure, stable operation, and suitability for rock sample collection and processing in lunar exploration missions.

[0005] This invention proposes a lunar rock and rock powder storage device for lunar resource exploration, specifically comprising a storage basket assembly, a temporary storage cup assembly, and an electrically controlled transmission assembly. The electrically controlled transmission assembly is located below the storage basket assembly, and is connected to and drives the temporary storage cup assembly to rotate. The storage basket assembly includes a frame and a storage basket, with the storage basket mounted on the frame. The temporary storage cup assembly includes a floating mechanism, a temporary storage cup, and an auxiliary support mechanism. The floating mechanism includes a spring and a base, and the base is connected to the electrically controlled transmission assembly. The temporary storage cup is slidably mounted on the base, with both ends of the cup connected to both ends of the base via a spring. The auxiliary support mechanism is mounted on the base, and its upper end is fastened to a vertical plate on the frame.

[0006] Furthermore, the temporary storage cup assembly also includes a striking mechanism, which includes a striking rod and a striking spring; one end of the striking spring is connected to the turbine shaft of the electronically controlled transmission assembly, and the other end is connected to one end of the striking rod; the middle of the striking rod is rotatably connected to the base, one end of which cooperates with the frame to compress the striking spring, and the other end strikes the bottom of the temporary storage cup.

[0007] Furthermore, the auxiliary support mechanism is equipped with spring clips.

[0008] Furthermore, the electronically controlled transmission assembly includes a stepper motor, a worm gear, and a turbine shaft. The output end of the stepper motor is connected to the worm gear, and the worm gear meshes with the turbine shaft. One end of the turbine shaft is connected to the base, and the turbine shaft is connected to a striking spring.

[0009] Furthermore, the electronically controlled transmission assembly also includes a housing and an end cover baffle, with the worm gear disposed inside the housing; the end cover baffle is fastened to the housing to protect the turbine shaft.

[0010] Furthermore, the frame is equipped with several railings, and the storage basket is placed between the railings.

[0011] Furthermore, the storage basket is provided with several grooves, into which the guardrail is embedded.

[0012] Furthermore, the storage basket has a conical bottom and a connecting rod at the top.

[0013] Furthermore, it also includes a locking and releasing mechanism, which includes a locking pin and a pressure rod. The locking pin is located on the storage basket; one end of the pressure rod is connected to the end of the turbine shaft, and the other end presses against the locking pin.

[0014] A sampling method using the aforementioned lunar rock and rock powder storage device for lunar resource exploration includes the following steps: Step 1: Before the lander launches, the electronically controlled transmission assembly drives the latching mechanism to press the storage basket firmly onto the frame; Step 2: After the lander lands, the electronically controlled transmission assembly drives the latch-release mechanism to unlock the storage basket; Step 3: The electric control transmission component drives the temporary storage cup assembly to rotate, and the auxiliary support mechanism and the upright plate on the frame are fastened together to improve the rigidity of the mechanism. At this time, the mouth of the temporary storage cup is facing upward. Step 4: After the picking device pours a certain amount of rock powder into the temporary storage cup, the floating mechanism assists the sampling device in docking with the temporary storage cup to take a sample. Step 5: After the sampling device finishes sampling, it detaches from the temporary storage cup. The temporary storage cup is then flipped over to pour out the rock powder. The knocking mechanism assists the temporary storage cup in discarding the sample. The electronically controlled transmission component drives the temporary storage cup assembly to rotate in the opposite direction until the cup opening faces upward. Step Six: The sampling device puts rock blocks into the storage basket. Repeat steps Four and Five until the storage basket is full. The robotic arm connects to the storage basket and lifts the basket. The power switch between the storage basket and the frame is disconnected, informing the system that the storage basket is separated from the frame. The robotic arm deflects and lifts the storage basket vertically upward.

[0016] (2) The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention uses a pressure bar and locking pin in conjunction with a compression spring to press the storage basket onto the frame, thereby locking the storage basket and ensuring that the storage basket does not fall off before the lander lands on the moon.

[0017] (3) The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention improves the structural rigidity of the temporary storage cup assembly by setting up an auxiliary support mechanism and frame, and prevents the turbine shaft from being bent when the temporary storage cup and the sampling device are connected.

[0018] (4) The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention uses a floating mechanism to compensate for displacement when the sampling device and the temporary storage cup are docked, thus ensuring smooth sampling.

[0019] (5) The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention uses a set tapping mechanism to tap the bottom of the temporary storage cup when discarding the sample, so as to assist in the discarding of the sample and ensure that there is no rock powder residue in the temporary storage cup.

[0025] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Specific implementation method one: See Figures 1-5This embodiment is described in detail. The lunar rock and rock powder storage device for lunar resource exploration described in this embodiment specifically includes a storage basket assembly 1, a temporary storage cup assembly 2, and an electrically controlled transmission assembly 3. The electrically controlled transmission assembly 3 is located below the storage basket assembly 1, and is connected to and drives the temporary storage cup assembly 2 to rotate. The storage basket assembly 1 includes a frame 11, several guardrails 12, and a storage basket 13. The storage basket 13 is disposed on the frame 11 and placed between the guardrails 12. The storage basket 13 is provided with several grooves 133, and the guardrails 12 are embedded in the grooves 133. The bottom of the storage basket 13 is provided with a conical tip 131, and the upper end is provided with a connecting rod 132. The conical tip 131 has a conical structure and cooperates with the frame 11. The connecting rod 132 is used to separate the storage basket 13 from the frame 11.

[0027] The temporary storage cup assembly 2 includes a floating mechanism 21, a temporary storage cup 22, a striking mechanism 23, and an auxiliary support mechanism 24. The floating mechanism 21 includes a spring 211, a base 213, and a base 214 connected to an electric control transmission assembly 3. The temporary storage cup 22 is slidably mounted on the base 214. Both ends of the temporary storage cup 22 are connected to both ends of the base 214 via a spring 211. One end of the spring 211 is connected to the edge of the base 214 via a bolt 212, and the other end is connected to the temporary storage cup 22 via a pin or bolt. This is used to assist in the collection of rock powder samples and to compensate for displacement when the sampling device and the temporary storage cup 22 are docked. At the same time, the temporary storage cup 22 can automatically return to the center under the action of the spring 211. The striking mechanism 23 includes a striking rod 231 and a striking spring 232. One end of the striking spring 232 is connected to the turbine shaft 34 of the electronically controlled transmission assembly 3, and the other end is connected to one end of the striking rod 231. The middle part of the striking rod 231 is rotatably connected to the base 214. The end connecting the striking spring 232 and the frame 11 cooperates to compress the striking spring 232 during the rotation of the device, and then releases it, so that the other end strikes the bottom of the temporary storage cup 22. The auxiliary support mechanism 24 is set on the base 214, and its upper end is fastened together with the upright plate on the frame 11 to improve the rigidity of the structure. The auxiliary support mechanism 24 is provided with a spring piece 241 on the plane in contact with the upright plate on the frame 11, such as... Figure 3 As shown; the spring piece 241 is used to prevent the auxiliary support mechanism 24 and the upright plate from making rigid contact.

[0028] The electronically controlled transmission assembly 3 includes a stepper motor 31, a worm gear 33, and a turbine shaft 34. The output end of the stepper motor 31 is connected to the worm gear 33 via a coupling 32, and the worm gear 33 meshes with the turbine shaft 34. One end of the turbine shaft 34 is connected to the base 214, and the turbine shaft 34 is connected to a striking spring 232. The electronically controlled transmission assembly 3 also includes a housing 36 and an end cover baffle 37. The worm gear 33 is disposed inside the housing 36, and a cylindrical roller bearing 35 is disposed between the worm gear 33 and the housing 36. The end cover baffle 37 is fastened to the housing 36 by screws 38 to protect the turbine shaft 34. The housing 36 and the end cover baffle 37 seal the interior to prevent dust particle contamination.

[0029] It also includes a locking and releasing mechanism 4, which includes a locking pin 41 and a pressure rod 42. The locking pin 41 is set on the storage basket 13. One end of the pressure rod 42 is connected to the other end of the turbine shaft 34, and the other end of the pressure rod 42 presses against the locking pin 41. Before the lander is launched, the pressure rod 42 presses the locking pin 41, and the locking pin 41 compresses the spring to press the storage basket 13 onto the frame 11, thus completing the locking action before launch.

[0030] A sampling method using the lunar rock and rock powder storage device for lunar resource exploration as described in claim 9, characterized by comprising the following steps: Step 1: Start the stepper motor 31. The stepper motor 31, together with the worm gear shaft 34 and the worm 33, forms a reducer, causing the worm gear shaft 34 to drive different loads on its left and right sides respectively. The right side drives the pressure rod 42 on the rotating shaft to lock the storage basket 13, while the left side controls the temporary storage cup 22 to flip for sample receiving and discarding. Before the lander launches, the stepper motor 31 drives the worm gear shaft 34 so that the pressure rod 42 at the right end presses against the locking pin 41 of the locking and releasing mechanism. The locking pin 41 compresses the spring, pressing the storage basket 13 firmly onto the frame 11, completing the pre-launch locking. Figure 1 As shown; Step 2: After the lander lands on the lunar surface, the stepper motor 31 is started. The stepper motor 31 drives the worm gear 33 to rotate the worm wheel shaft 34 in the forward direction. At this time, the pressure rod 42 is lifted, and the locking 41 in the locking and releasing mechanism is lifted upward under the action of the spring. During the rotation of the worm wheel shaft 34, the pressure rod 42 is completely separated from the locking pin 41, and the storage basket 13 is unlocked. Step 3: Stepper motor 31 drives temporary storage cup assembly 2 to rotate to 90° via worm gear 33 and worm wheel shaft 34, then stops. Auxiliary support mechanism 24, driven by worm wheel shaft 34, engages with the upright plate on frame 11 via spring piece 241, thereby increasing the rigidity of the mechanism. At this time, the opening of temporary storage cup 22 faces upwards. Figure 2 As shown; Step 4: After the picking shovel of the picking device pours a certain amount of rock powder into the temporary storage cup 22, the spring 211 of the floating mechanism 21 extends and retracts to assist the sampling device in docking with the temporary storage cup 22 to take a sample, thus completing the sampling of the sampling tube in the temporary storage cup 22. Step 5: After the sampling device completes sampling and moves away from the temporary storage cup 22 by a certain distance, the temporary storage cup 22 rotates 180° again and stops. At this time, the rock powder is poured out of the cup with the cup mouth facing downward. During the rotation, one end of the striking rod 231 and the striking spring 232 of the striking mechanism 23 comes into contact with the frame 11, compressing the striking spring 232 and then releasing it. When the striking spring 232 is released, the other end of the striking rod 231 strikes the bottom of the temporary storage cup 22, thereby assisting in the disposal of the rock powder in the temporary storage cup 22. The electric control transmission component 3 drives the temporary storage cup component 2 to rotate 180° in the opposite direction until the cup mouth faces upward. Step Six: The sampling device places rock blocks into the storage basket 13. Then, steps Four and Five are repeated until the storage basket 13 is full. The robotic arm engages with the docking rod of the storage basket 13 via the docking locking rod. When the robotic arm connects with the storage basket 13 and drives the storage basket 13 to rise, the power switch located between the bottom of the storage basket 13 and the frame 11 is disconnected. The on / off circuit informs the system whether the storage basket 13 and the frame 11 are separated. At this time, the robotic arm shaft deflects at a small angle, so that the storage basket 13 is in a vertical state and lifted upward, realizing the docking and separation of the storage basket 13.

[0031] In summary, the lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention, through the electronically controlled transmission component 3, generates different loads on the left and right sides of the turbine shaft 34. The right side drives the pressure rod 42 to lock and release, while the left side drives the temporary storage cup 22 to complete sampling and disposal, thus improving the device efficiency. The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention, through the pressure rod 42 and locking pin 41 working in conjunction with a compression spring, presses the storage basket 13 firmly onto the frame 11, achieving locking of the storage basket 13 and ensuring that it does not fall off before the lander lands on the moon. The lunar rock and rock powder storage device and sampling method for lunar resource exploration described in this invention, through the auxiliary support mechanism 24 working in conjunction with the frame 11, improves the structural rigidity of the temporary storage cup component 2, preventing the turbine shaft 34 from bending when the temporary storage cup 22 and the sampling device are connected. The present invention discloses a lunar rock and rock powder storage device and sampling method for lunar resource exploration. A floating mechanism 21 compensates for displacement when the sampling device and the temporary storage cup 22 are docked, ensuring smooth sampling. The present invention also discloses a tapping mechanism 23 that taps the bottom of the temporary storage cup 22 during sample disposal, assisting in sample disposal and ensuring no rock powder residue remains in the temporary storage cup 22.
