Description

Technical Field

[0002] During the manned lunar mission, astronauts will conduct multiple extravehicular activities on the lunar surface. During the lunar surface mission, lunar dust will adhere to the surface of the lunar suits and equipment. When astronauts carry items into the cabin, lunar dust will enter the cabin and pollute the cabin environment. Therefore, it is necessary to design a dust removal brush specifically for astronauts to remove dust outside the cabin to complete the lunar dust removal work outside the cabin.

[0003] Parameters of the dust removal brush, such as the bristle material, bristle length, and bristle density, will significantly affect its dust removal effect. Therefore, during the design process of the extravehicular dust removal brush tool used in the manned lunar mission, it is necessary to test the dust removal effect of single-machine test pieces of dust removal brushes with different parameter specifications, evaluate and compare the dust removal effects, and select the dust removal brush design parameters with the best effect.

[0004] At present, in the dust removal effect test, dust removal is mainly completed by hand-held dust removal brushes. In the manual process, it is difficult to control the speed and strength of the dust removal brushes for multiple times, which increases the variables of the test. In addition, in the effect evaluation after the dust removal is completed, comparison is made by relying on naked eye observation, which has large errors and lacks quantifiable evaluation indicators.

DETAILED DESCRIPTION

[0054] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0055] Combine the following Figure 1-Figure 5 , describes the lunar dust removal effect test device of the manned lunar module external dust removal brush provided in the embodiment of the present application.

[0056] Reference Figure 1 As shown, an embodiment of the present application provides a test device for the lunar dust removal effect of a dust removal brush outside a manned lunar module, comprising a test platform 100, a moving mechanism 200 and a dust removal quantification mechanism. The test platform 100 is kept parallel to the ground. The test platform 100 is used to place an object to be dusted, and the surface of the object to be dusted is parallel to the test platform 100. Specifically, the object to be dusted is made of cloth, which is spread flat on the test platform 100. During the test, simulated lunar dust is evenly sprinkled on the surface of the object to be dusted to prevent the simulated lunar dust on the object to be dusted from sliding under the action of gravity and affecting the test; the moving mechanism 200 is arranged on a side of the test platform 100 away from the ground, and the dust removal brush to be tested is installed on the moving mechanism 200. The dust removal brush to be tested is driven by the moving mechanism 200 to move along a preset path to perform dust removal on the surface of the object to be dusted several times; the dust removal quantification mechanism is used to quantify the dust removal effect of the dust removal brush to be tested.

[0057] By utilizing the technical solution provided in the above embodiment, the dust removal brush to be tested is driven to move along a preset path through the moving mechanism 200 to achieve dust removal on the surface of the object to be dusted. The strength and speed of the dust removal brush to be tested in cleaning the surface of the object to be dusted can be consistent each time, thereby ensuring that the test variables are only the parameters of the dust removal brush itself (bristle material, bristle length, bristle density, etc.), which can effectively improve the accuracy and stability of the test data.

[0058] In some specific embodiments, the dust removal quantification mechanism includes at least one of a weighing instrument, a solar light absorption rate measuring instrument, and a microscope imager. For example, the dust removal quantification mechanism includes a weighing instrument, a solar light absorption rate measuring instrument, and a microscope imager. The weighing instrument is used to measure the amount of lunar dust on the object to be removed at different dust removal stages. The solar light absorption rate measuring instrument is used to measure the solar light absorption rate of the object to be removed after dust removal. According to the characteristics that the more simulated lunar dust on the surface of the object to be removed, the darker the color, and the higher the absorption rate, the object to be removed is placed under the solar absorption rate measuring instrument, and the solar light absorption rate on the surface of the object to be removed is recorded to obtain the amount of lunar dust on the surface of the object to be removed. The microscope imager is used to measure the lunar dust coverage of the object to be removed after dust removal. In this way, by establishing a multi-dimensional and multi-faceted dust removal evaluation system, a quantifiable evaluation index is provided for the dust removal effect test of the dust removal brush.

[0059] Specifically, the weighing instrument is arranged on the test platform 100, and the weighing instrument uses an electronic scale with an accuracy of 0.001g. The dust to be removed is spread on the weighing instrument, so that the amount of lunar dust on the dust to be removed can be accurately measured without moving the test position of the dust to be removed, which is conducive to maintaining the original distribution state of the lunar dust on the dust to be removed after each dust removal. In some specific embodiments, the area of ​​the weighing surface of the weighing instrument is equal to the spread area of ​​the dust to be removed, and the dust to be removed can completely cover the weighing surface of the weighing instrument. In this way, the dust to be removed can be completely placed on the weighing instrument, ensuring that the weight data of the weighing instrument is completely derived from the lunar dust on the dust to be removed, and avoiding the situation where part of the lunar dust swept from the dust to be removed is re-counted into the weighing data of the weighing instrument.

[0060] Reference Figure 1 As shown, in some embodiments provided in the present application, the device also includes a support seat 210, a guide slide 220, a movable slide 230 and a driver 240. The support seat 210 is fixed to the test platform 100 by welding or bolts, and the guide slide 220, the movable slide 230 and the driver 240 are all arranged on the support seat 210; specifically, the guide slide 220 includes a guide screw and a guide light rod, and a threaded hole and a through hole are opened on the movable slide 230. The threaded hole is threadedly matched with the guide screw, and the through hole is slidingly matched with the guide light rod. The driver 240 adopts a servo motor, and the output shaft of the servo motor is coaxially connected with the guide screw through a coupling. Under the drive of the servo motor, the guide screw rotates along its own axis, so that the movable slide 230 moves along the axial direction of the guide screw. Since the dust removal brush to be tested is installed on the movable slide 230, it can drive the dust removal brush to be tested to move at a uniform speed along the axial direction of the guide screw. By adjusting the rotation speed of the driver 240, the moving speed of the dust brush to be tested can be adjusted, thereby ensuring that the strength and speed of the dust brush to be tested cleaning the surface of the dust object are consistent each time, ensuring that the test variables are only the parameters of the dust brush itself, and effectively improving the accuracy of the test data.

[0061] Reference Figure 1 , Figure 2 As shown, the device also includes a height adjustment component 300, which is arranged on the movable slide 230. The height adjustment component 300 includes a lifting plate 310, an adjusting shaft 330 and an adjusting wheel 340. The lifting plate 310 is vertically arranged, and a rectangular hole is opened on the lifting plate 310. A rack is vertically arranged on the right inner wall of the rectangular hole, and the rack has internal teeth 320. The left inner wall of the rectangular hole is a plane; one end of the adjusting shaft 330 is rotatably connected to the movable slide 230 through a bearing seat, and the other end passes through the rectangular hole; The adjusting wheel 340 has external teeth, the outer diameter of the adjusting wheel 340 is consistent with the width of the rectangular hole, the external teeth of the adjusting wheel 340 are in contact with the left inner wall of the rectangular hole, and the external teeth of the adjusting wheel 340 are meshed with the internal teeth 320 of the right inner wall of the rectangular hole. By rotating the adjusting shaft 330, the external teeth and the internal teeth 320 can be meshed with each other, so that the lifting plate 310 moves up and down in the vertical direction to approach or move away from the test platform 100, so as to control the height of the lower end surface of the dust removal brush to be tested with different bristle lengths to be consistent. Specifically, a scale is set in the vertical direction on the lifting plate 310. According to the bristle length of the dust removal brush to be tested, the height of the dust removal brush to be tested can be accurately adjusted by moving a certain scale in accordance with the bristle length of the dust removal brush to be tested.

[0062] Reference Figure 3 , Figure 4 As shown, in some specific embodiments, the interior of the adjusting shaft 330 has a gear cavity, the inner wall of the gear cavity is provided with a gear ring 610, and a fine adjustment component is also provided in the gear cavity, the fine adjustment component includes a central gear 620, a side gear 630, a central shaft 640 and a knob 650, the end of the adjusting shaft 330 is provided with a central hole connected to the gear cavity, the central shaft 640 is passed through the central hole, the central gear 620 is sleeved on the inner end of the central shaft 640, the knob 650 is sleeved on the outer end of the central shaft 640, the side gear 630 is installed on the inner wall of the gear cavity through the wheel axle, and when the knob 650 is pushed inward along the axial direction, the central gear 620 is located Figure 3 When the side gear 630 is in the first position, it only meshes with the ring gear 610. At this time, turning the knob 650 will not drive the adjustment shaft 330 to rotate. When the knob 650 is pushed outward along the axial direction, the central gear 620 is in the first position. Figure 4When the lifting plate 310 is in the second position, the side gear 630 is meshed with the ring gear 610 and the center gear 620 respectively. At this time, turning the knob 650 can drive the adjusting shaft 330 to rotate, and then drive the adjusting wheel 340 to rotate, so that the lifting plate 310 is lifted and lowered; a limiting convex ring 660 is also provided on the center shaft 640. When the limiting convex ring 660 is against the inner wall of the gear cavity, it indicates that the center gear 620 has reached the second position; in this way, by setting the center gear 620, the side gear 630 and the ring gear 610, the lifting distance of the lifting plate 310 can be reduced while rotating the same number of circles, so that the height of the dust removal brush to be tested can be accurately adjusted at a micro distance. Generally, first, by rotating the adjustment shaft 330, the adjustment wheel 340 is directly driven to make a rough adjustment of the dust removal brush to be tested over a large distance, saving time; then, by pushing the knob 650 outward and rotating the knob 650, the center gear 620, the side gear 630 and the ring gear 610 are engaged with each other, thereby driving the adjustment shaft 330 and the adjustment wheel 340 to make a precise adjustment of the dust removal brush to be tested over a micro distance, which is beneficial to ensure that the height and strength of each cleaning are consistent.

[0063] Reference Figure 1 As shown, the device also includes a mounting plate 400, which is vertically mounted on the lower end of the lifting plate 310, and a limiting plane 410 is formed on the side of the mounting plate 400 close to the test platform 100, and the limiting plane 410 is parallel to the test platform 100, and the limiting plane 410 is used to abut against the upper end of the dust removal brush to be tested to keep the lower end surface of the dust removal brush to be tested parallel to the test platform 100, while preventing the dust removal brush to be tested from moving up; the mounting plate 400 is detachably connected to the dust removal brush to be tested, for example, the mounting plate 400 and the dust removal brush to be tested are clamped by a groove and protrusion structure or connected by a clamp, so as to realize quick disassembly and quick assembly between the dust removal brush to be tested and the mounting plate 400; refer to Figure 5 As shown, in some embodiments, a mounting clamp is provided on the mounting plate 400, and the mounting clamp includes two clamp handles 710, the middle parts of the two clamp handles 710 are rotatably connected, and a clamp plate 720 is fixed to the end of the clamp handle 710, and a movable plate 730 is provided on the inner side of the clamp plate 720, and the movable plate 730 and the clamp plate 720 are connected by a spring 740. When clamping the dust brush to be tested, the left and right sides of the dust brush to be tested are respectively abutted against the inner side of the movable plate 730. On the one hand, it can adapt to dust brushes to be tested of different widths, and on the other hand, it can keep the movable plate 730 in surface contact with the left and right sides of the dust brush to be tested to prevent the dust brush to be tested from slipping or shifting.

[0064] Reference Figure 1As shown, the device also includes a displacement sensor 500, which is arranged on the support seat 210 and is used to detect the position of the movable slide 230 on the guide slide 220 in real time. The displacement sensor 500 is used to know the number of times the movable slide 230 goes back and forth on the guide slide 220. Specifically, the movable slide 230 goes back and forth on the guide slide 220 once, which means that the dust removal brush to be tested cleans the object to be dusted once (the dust removal brush to be tested does not clean the object to be dusted on the return journey), thereby obtaining the number of times the dust removal brush to be tested cleans the object to be dusted; specifically, the displacement sensor 500 is electrically connected to the weighing instrument, and each time the dust removal brush to be tested cleans the object to be dusted once, the displacement sensor 500 sends a signal to the weighing instrument, and the weighing instrument weighs the amount of dust on the object to be dusted in time.
