Description

Technical Field

[0001] The utility model relates to the technical field of lunar crater formation simulation, in particular to a lunar crater formation simulation teaching aid for teaching. Background Art

[0002] A crater usually refers to a pit with a bowl-shaped structure. The surface of the moon is covered with large and small circular pits, called lunar craters. Most of the lunar craters are surrounded by craters that are higher than the lunar surface. There are more craters on the back of the moon. One explanation for the formation of craters is the impact of meteoroids and meteorites.

[0003] In the teaching of the formation of lunar craters, students are required to make guesses about the formation of craters and find ways to verify their guesses. However, teaching is mostly assisted by books or videos, and tray-type teaching aids are also used for auxiliary teaching. The outline of the tray teaching aid is square, while the outline of the moon is arc-shaped. The craters displayed on the tray only represent the local situation on the lunar surface, and cannot reflect the distribution characteristics of the craters on the lunar surface as a whole. Moreover, when simulating meteorite impacts, they all start from the same angle, which cannot reflect the spatial distribution of celestial bodies in the universe, nor can they reflect the relationship between the earth and the moon. It is relatively abstract and cannot simulate the craters formed by celestial bodies impacting the moon in a three-dimensional way. As a result, students lack the concept of three-dimensional cosmic space when learning, which makes learning difficult and the teaching effect weak. For this reason, we propose a teaching simulation teaching aid for the formation of lunar craters under the impact theory. Utility Model Content

[0036] Among them, the surface covering material of the lunar model 4 is ultra-light clay, which has a certain plasticity. When it is hit, pits are produced, which can simulate the formation of craters. Moreover, since ultra-light clay has a good shaping effect and can be preserved for a long time, the lunar model 4 can be used for simulation teaching and can also be used as a model for exhibition and observation.

[0037] One end of the two sets of telescopic links 17 is fixedly connected to a plug plate 18, and the upper end surface of the plug plate 18 is fixedly connected to a T-shaped plate 19. The outside of the two sets of telescopic links 17 is sleeved with a support spring. The outer walls of the adjusting rod 17 and the adjusting rod 28 are provided with a plurality of groups of slots 21, and the slots 21 are matched with the plug plate 18. Under the action of the elastic force of the support spring, the telescopic links 17 are extended, thereby driving one end of the plug plate 18 to be inserted into the corresponding slot 21, thereby fixing the position of the adjusting rod 17.

[0038] An annular groove is provided on the inner wall of the annular base 2, and two groups of limit blocks 14 are fixedly connected to the outer wall of the plug-in shaft 12, and the limit blocks 14 are matched with the annular groove. An annular plate 13 is fixedly installed on the outer wall of the plug-in shaft 12 and located above the annular base 2. A fixing rod 15 is inserted on the upper end surface of the annular plate 13. A plurality of fixing holes are provided on the upper end surface of the annular base 2, and the fixing holes are matched with the fixing rod 15. A celestial model 11 is arranged directly below the hanging rope 10, and a hook 32 is fixedly installed on the outer wall of the celestial model 11. When the plug-in shaft 12 is rotated, the limit blocks 14 move with it pressing the annular groove, which can make the plug-in shaft 12 more stable when rotating and avoid detachment from the annular base 2.

[0039] The materials of each group of celestial body models 11 can be metal, wood, plastic, ceramic, stone, foam, elastic ball, etc. of different sizes, so as to simulate celestial bodies of different materials existing in the universe.

[0040] In the classroom of the lunar crater simulation teaching, the upper ends of the hanging ropes 10 of each group can be hung on the hooks 9 of each group, and the hanging ropes 10 of each group can be hung under the adjusting rod 8. Then, the celestial body model 11 to be used for simulating the impact on the lunar crater can be hung on the outside of the hanging rope 10 near the bottom through the hook 32. Subsequently, the hanging ropes 10 with celestial body models 11 of different masses can be hung on the corresponding hooks 9 as needed to adjust the distance between the hanging celestial body model 11 and the moon. The distance is set, and then the insertion shaft 12 is rotated to drive the support rod 1 5 and the adjusting rod 1 7 to rotate, and then the support rod 2 6 and the adjusting rod 2 8 connected by the connecting block 22 are driven to rotate, and the groups of celestial models 11 hung on the adjusting rod 2 8 by the hanging rope 10 are driven to rotate, and the placement angle between each group of celestial models 11 and the lunar model 4 is adjusted. After the adjustment, one end of the fixing rod 15 can be inserted into the corresponding fixing hole through the annular plate 13 to fix the position of the insertion shaft 12, thereby fixing the position of each group of celestial models 11 at this time;

[0041] After adjusting the placement angle between the celestial model 11 and the lunar model 4, the T-shaped plate 19 in the adjustment mechanism 20 can be moved along the U-shaped frame 16 in the direction away from the support rod 15, thereby driving the plug plate 18 to move out of the slot 21, and the telescopic connecting rod 17 and the supporting spring are both compressed. At this time, the adjusting rod 17 can be pulled upward along the inside of the support rod 15 to move the adjusting rod 28 upward, thereby driving each group of celestial models 11 to move upward and adjust the height of each group of celestial models 11. After adjustment, the T-shaped plate 19 is released. At this time, under the action of the elastic force of the supporting spring, the telescopic connecting rod 17 is driven to extend, thereby driving one end of the plug plate 18 to insert into the corresponding slot 21, fixing the position of the adjusting rod 17, thereby fixing the height of each group of celestial models 11. Similarly, the adjusting rod 28 can be pulled along the support rod 26 to drive each group of celestial models 11 to move horizontally. Adjust the lateral position of each group of celestial body models 11. At this time, the position of each group of celestial body models 11 is completely adjusted, and they can be moved in turn to impact the lunar model 4. Since the lunar model 4 has a certain plasticity, it will produce pits and form craters when hit by the celestial body model 11, simulating the formation of lunar craters, and conducting simulated teaching on the formation of lunar craters. Through the above operations, the characteristics of the universe are simulated, the cosmic environment of the moon is reflected, a three-dimensional simulation is formed, students' preliminary understanding of the concept of the universe is established, the difficulty of teaching and learning is reduced, and the simulation of celestial bodies of different masses in the universe hitting the moon from different angles, different heights and different distances from the moon to form craters is achieved. After the simulation is completed, since the clay covering the surface of the lunar model 4 has a certain plasticity, the pits after the impact can be restored, so that the simulation teaching aid can be used repeatedly.

[0042] See also Figure 2 and Figure 7 The fixing mechanism 31 includes a fixing block 23, which is sleeved on the outside of the hanging rope 10, and an extrusion block 24 is inserted into the outer wall of the fixing block 23. Frames 25 are fixedly installed on the outer wall of the fixing block 23 near both sides of the extrusion block 24, and cross bars 26 are fixedly installed inside the two groups of frames 25.

Movable grooves 27 are provided at the upper and lower ends of the slide plates 30, and blocks 28 are inserted into the two groups of movable grooves 27. Slots 29 are penetrated through the upper and lower inner walls of the frame 25, and the slots 29 are matched with the block 28. A reset spring is installed between one end of the block 28 and the bottom end of the movable groove 27. Under the action of the reset spring elastic force, the block 28 is inserted into the slot 29, so that the position of the extrusion block 24 can be fixed.

[0043] Among them, two groups of through holes are opened through the upper end of the fixed block 23, one end of the hanging rope 10 passes through one group of through holes from the bottom of the fixed block 23, and passes through the other group of through holes from the top, and the extrusion block 24 squeezes the hanging rope 10 inserted in the fixed block 23, so that the upper end of the hanging rope 10 is ring-shaped, which is used to be hung on the hook 1 9. Similarly, the lower end of the hanging rope 10 is also ring-shaped through another group of fixing mechanisms 31, which is used for hanging hook 2 32 and connecting the celestial body model 11.

[0044] Specifically, the squeezing block 24 is moved away from the fixed block 23 to release the squeezing of the hanging rope 10, and the two groups of slides 30 follow it to move along the cross bar 26 in the frame 25, and the two groups of clamping blocks 28 follow the movement of the slides 30, and the inclined surface of the clamping block 28 moves along the inner wall of the clamping slot 29, gradually moves out of the clamping slot 29, and shrinks inside the movable slot 27, and the reset spring is compressed. At this time, the free end of the hanging rope 10 can be pulled along the perforation, and the more it is pulled out, the shorter its overall hanging length is, and the higher the hanging height of the celestial model 11 hung at its bottom is, so that the height of the celestial model 11 can be further adjusted, the adjustable range of the height of the celestial model 11 is increased, and the teaching effect is improved. After adjustment, the squeezing block 24 can be used to squeeze the hanging rope 10 again to fix the hanging length of the hanging rope 10, and the clamping block 28 is re-inserted into the clamping slot 29 under the action of the elastic force of the reset spring, so that the position of the squeezing block 24 can be fixed.
