Description

Technical Field

[0001] This invention relates to a plume dust prevention opening and closing mechanism, specifically a double-roller pull-out type plume dust prevention opening and closing mechanism. This invention belongs to the technical field of lunar soil sample processing mechanisms. Background Technology

[0002] With continuous technological updates and iterations, the next phase of the lunar exploration mission plans to conduct in-situ analysis of lunar soil samples.

[0003] Unlike sampling missions, in-situ analysis does not require bringing samples back to Earth; instead, it involves extraction and analysis directly in orbit. Therefore, a lunar soil sample processing mechanism needs to be designed to process and extract lunar soil samples obtained in orbit. Any moving mechanism on the lunar surface faces significant risks. Highly adhesive lunar dust can cause the mechanism to jam, and the lunar rover will generate large plumes of dust during landing and movement, severely impacting the mechanism's operation and potentially causing it to fail completely. Therefore, it is necessary to design a plume-protection mechanism for the sample processing mechanism. Summary of the Invention

[0004] In order to solve the problem that the reliability of sample processing mechanisms is reduced or even directly fails due to the influence of plume dust on the lunar surface, thus preventing the smooth progress of sample processing tasks, this invention proposes a double-roller pull-out anti-plume dust opening and closing mechanism.

[0005] The technical solution adopted by the present invention to solve the above problems is as follows:

[0006] The present invention includes a drive motor, an active reel, a driven reel, an active sheave, a driven sheave, a rope, a fixed frame, and at least one skin. The fixed frame is installed at the sample inlet of the sample processing mechanism. The active reel and the driven reel are respectively installed on the bottom and top edges of the lower surface of the fixed frame, and the axes of the active reel and the driven reel are parallel to the center line of the fixed frame along its length. The left end of the active reel is fixedly connected to the output shaft of the drive motor through a coupling. The right end of the active reel is fitted with an active sheave, and the driven sheave is fitted on the right end of the driven reel. The active sheave and the driven sheave are connected by a rope. One end of the skin is fixedly connected to the active reel, and the other end of the skin overlaps the driven reel.

[0007] Furthermore, there are two skins, namely a first skin and a second skin, which are arranged from left to right along the length of the fixed frame.

[0008] Furthermore, one end of the first skin is fixedly connected to the active roll, and the other end overlaps the driven roll; one end of the second skin is fixedly connected to the driven roll, and the other end overlaps the active roll.

[0009] Furthermore, the fixed frame is a rectangular frame, and the top edge of the lower surface of the fixed frame is provided with a through hole for the driven reel to pass through; the bottom edge of the lower surface of the fixed frame is provided with a through hole for the driving reel to pass through.

[0010] The beneficial effects of this invention are:

[0011] 1. This invention effectively avoids the impact of plume dust on the sample processing mechanism, improves the reliability of the sample processing mechanism, and thus ensures the smooth progress of the sample processing task.

[0012] 2. This invention uses the pull-out of the roller to drive the movement of the skin, which can completely cover the sample inlet area, effectively preventing dust from entering the sample processing mechanism, minimizing the risk of mechanism jamming, and improving the safety and reliability of the mechanism.

[0013] 3. The present invention has a simple structure, ingenious design, and strong reusability. By pulling the skin with a dual-axis rotation, the plume dust is effectively reduced without affecting sample delivery.

[0014] 4. When the present invention has two sample inlets, two skins can be arranged to accommodate different types of samples. By rotating the motor forward and backward, the skins at different positions can be pulled out, so that the two sample inlets are covered and exposed in turn, so as to receive different types of samples. This prevents the risk of plume dust from entering either sample inlet. Attached Figure Description

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

The fixed frame 10 is installed at the sample inlet 9 of the sample processing mechanism 1. The active roll 4 and the driven roll 5 are respectively installed on the bottom and top edges of the lower surface of the fixed frame 10, and the axes of the active roll 4 and the driven roll 5 are parallel to the center line of the fixed frame 10 along its length. The left end of the active roll 4 is fixedly connected to the output shaft of the drive motor 3 through a coupling. The right end of the active roll 4 is fitted with the active rope pulley 7, and the driven rope pulley 6 is fitted on the right end of the driven roll 5. The active rope pulley 7 and the driven rope pulley 6 are connected by the rope 8. One end of the skin is fixedly connected to the active roll 4, and the other end of the skin overlaps the driven roll 5.

[0021] Specific Implementation Method Two: Combining Figures 1 to 3 This embodiment describes a method where two skins are used: a first skin 11 and a second skin 12. The first skin 11 and the second skin 12 are arranged from left to right along the length of the fixed frame 10. Two sample inlets are provided to receive different types of samples, and two skins are arranged to accommodate different sample types.

[0022] One end of the first skin 11 is fixedly connected to the driving roller 4, and the other end overlaps the driven roller 5; one end of the second skin 12 is fixedly connected to the driven roller 5, and the other end overlaps the driving roller 4.

[0023] The other components and connections are the same as in Specific Implementation Method 1.

[0024] Specific implementation method three: Combining Figures 1 to 3 In this embodiment, the fixed frame 10 is a rectangular frame. The top edge of the lower surface of the fixed frame 10 is provided with a through hole for the driven roller 5 to pass through; the bottom edge of the lower surface of the fixed frame 10 is provided with a through hole for the driven roller 4 to pass through.

[0025] Other components and connections are the same as in specific implementation method one or two.

[0026] Working principle:

[0027] The sample processing mechanism of the present invention is isolated from a large amount of lunar dust by a dust cover 2 when it is in standby mode; when it is in working mode, the mechanism needs to receive lunar soil samples for processing and analysis.

[0028] (i) When the sample processing mechanism has a sample inlet 9, when the sample processing mechanism is in the initial state, the first skin 11 covers the entire sample receiving area, and the entire mechanism is in a sealed and dustproof state.

[0029] After the sampling mechanism collects lunar soil samples, the samples are transferred to the sample processing unit 1 via a transfer mechanism for subsequent analysis and extraction. Before the samples enter the processing unit, the cover of the first skin 11 is removed, and the samples enter the processing unit through the sample inlet 9. The drive motor 3 rotates forward, driving the active reel 4 to rotate via a coupling. The active reel 4 drives the active rope wheel 7, which is coaxially fixed to it, to rotate. This, in turn, drives the driven rope wheel 6 to rotate via a rope 8. Both rotate in the same direction, ultimately driving the driven reel 5 to rotate. During this process, the first skin 11 is rolled up by the rotation of the active reel 4, exposing the sample inlet 9, thus completing the preparatory actions for sample collection.

[0030] Once the sample enters the processing mechanism, the first skin 11 begins to retract to its initial covering state, and sample processing and analysis begin. The drive motor 3 reverses, driving the active reel 4 to rotate via a coupling. The active reel 4 drives the active pulley 7, which is coaxially fixed to it, to rotate. This, in turn, drives the driven pulley 6 via a rope 8, ultimately causing the driven reel 5 to rotate. The first skin 11, coiled on the active reel, unwinds in the opposite direction, re-covering the entire sample delivery area.

[0031] (ii) When the sample processing mechanism is provided with two sample inlets 9, the two sample inlets 9 are used to receive different types of products, and the first skin 11 and the second skin 12 are arranged to accommodate different types of samples.

[0032] When the sample processing mechanism is in its initial state, the first skin 11 and the second skin 12 cover the entire sample injection area, and the entire mechanism is in a sealed and dustproof state.

[0033] After the sampling mechanism collects lunar soil samples, the samples are transferred to the sample processing unit 1 via a transfer mechanism for subsequent analysis and extraction. Before the samples enter the processing unit, the first skin 11 is removed, and sample type 1 enters the sample processing unit 1 through the left sample inlet 9. The drive motor 3 rotates forward, driving the active reel 4 to rotate via a coupling. The active reel 4 drives the active rope wheel 7, which is coaxially fixed to it, to rotate. This, in turn, drives the driven rope wheel 6 to rotate via a rope 8. Both rotate in the same direction, ultimately driving the driven reel 5 to rotate. During this process, the first skin 11 is rolled up by the rotation of the active reel 4, while the second skin 12 remains stationary, exposing the left sample inlet 9. The pre-sample preparation is complete.

[0034] Once the sample enters the processing mechanism, the first skin 11 begins to retract to its initial covering state, and sample processing and analysis begin. The drive motor 3 reverses, driving the active reel 4 to rotate via the coupling. The active reel 4 drives the active pulley 7, which is coaxially fixed to it, to rotate. This, in turn, drives the driven pulley 6 via the rope 8, ultimately causing the driven reel 5 to rotate. The first skin 11, coiled on the active reel, unwinds and re-covers the left sample inlet 9 area. Simultaneously, the driven reel 5 slowly rolls up the second skin 12, fully exposing the right sample inlet 9. Sample type 2 is then fed through the right sample inlet 9 via the sample delivery mechanism. The above actions are repeated for two different types of samples, pulling the skin at different positions to achieve the desired effect.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
