[0020] Background plate 02 is fixed on the back side of cuboid base 01 by bolt or buckle, and is convenient to assemble and disassemble when using or storing, and background plate 02 is dark (such as black), and can also be other darker colors, and the black background plate 02 is more conducive to reducing light interference and enhancing contrast, and the effect is better during experiment simulation, and the shape of the background plate 02 is not particularly limited here, and the shape of the background plate 02 that can achieve the same or equivalent effect all belong to the protection scope of the utility model. The orbit simulation 11 is used for simulating the revolution of simulation moon 04 around the earth, which can be a track arranged on the upper surface of base 01, or a groove arranged on the upper surface of base 01, and simulation moon 04 changes position in the orbit simulation 11 to simulate the revolution of the moon around the earth, and simulation moon 04 is located between simulation earth 05 and simulation sun 03 to simulate the position distribution of celestial bodies when the solar eclipse is formed, and simulation sun 03 is fixed on the upper surface of base 01, and its position is not particularly limited here, and it is more beautiful to arrange simulation sun 03 on the center line of base 01.

[0021] The simulation earth 05 and the simulation sun 03 are located on the same central axis, which simplifies the relative relationship of the earth, the sun and the moon in the solar system, fixes the simulation sun 03 and the simulation earth 05, and focuses on the specific blocking of the simulation sun 03 caused by the different spatial positions of the simulation moon 04 between the simulation earth 05 and the simulation sun 03, so that students can truly compare the three different conditions of "total solar eclipse", "annular solar eclipse" and "partial solar eclipse" that can be observed on the earth in real life. By changing the position of the simulation moon 04 in the simulation orbit 11, the simulation of its revolution around the earth is realized, and the simulation moon 04 is placed between the simulation earth 05 and the simulation sun 03. According to the different blocking of the simulation moon 04 to the simulation sun 03, students can observe and infer that the moon's orbit is not only different in distance, but also different in height, and then realize the development from simple popular science knowledge to real cognitive thinking, effectively break through the teaching key points and difficulties, and achieve the teaching requirements of the national curriculum standard.

[0022] As shown in Figure 1 , the simulation orbit 11 includes a first arc-shaped track 111, a second arc-shaped track 112, a third arc-shaped track 113, and a straight track 114 connecting the first arc-shaped track 111, the second arc-shaped track 112 and the third arc-shaped track 113. The center line of the straight track 114 coincides with the center line between the simulation earth 05 and the simulation sun 03.

[0023] The simulation orbit 11 is provided with three arc-shaped tracks for simulating the revolution of the moon around the earth, i.e. the first arc-shaped track 111, the second arc-shaped track 112 and the third arc-shaped track 113. The straight track 114 is connected with the three arc-shaped tracks, and the simulation moon 04 can be slid into any one of the three arc-shaped tracks through the straight track 114, so as to change the distance between the simulation moon 04 and the simulation earth 05, and intuitively display that the orbit of the moon around the earth has different distances, so that students can more intuitively observe that when the distance between the moon and the earth changes, different forms of solar eclipse phenomenon will appear, and students can have a deeper understanding of the motion of celestial bodies.

[0024] As shown in Figure 1 , 2 , the simulation sun 03 is provided with a first support 31, the simulation moon 04 is provided with a second support 41, and the simulation earth 05 is provided with a third support 51. The simulation sun 03 is fixedly arranged on the upper surface of the base 01 through the first support 31, the simulation moon 04 is slidably arranged in the simulation orbit 11 through the second support 41, and the simulation earth 05 is fixedly arranged on the side wall of the base 01 through the third support 51. The second support 41 and the third support 51 are both provided with scales 42, and the height of the simulation moon 04 and the simulation earth 05 can be adjusted according to the scales 42.

[0025] The simulated sun 03 is fixed on the first support 31 by bolts or buckles, and the first support 31 is also fixed on the upper surface of the base 01 by bolts or buckles, so that the first support 31 is spaced apart from the upper surface of the base 01 by a certain distance, so as to avoid visual deviation caused by too close distance; the simulated earth 05 is slidingly sleeved on the third support 51, and the two can be connected through a sliding groove, and when the height is adjusted to the required height, the two are fixed by bolts, or the two are connected through a locking pin, so as to adjust the height of the simulated earth 05 and ensure that the simulated earth 05 matches the simulated sun 03, and the third support 51 is fixed on the front side wall of the base 01 by bolts or buckles.

[0026] The second support 41 is provided with a protrusion or a pulley matched with the revolution simulation track 11 at the lower end, and the upper end is slidingly connected with the simulated moon 04, and the two can be connected through a sliding groove, or the two can be connected through a locking pin, or other connection modes capable of achieving equivalent or same effect, so that the simulated moon 04 can not only slide in the revolution simulation track 11 through the second support 41, but also adjust the relative position between the simulated moon 04 and the simulated earth 05, and the height between the simulated moon 04 and the revolution simulation track 11 can be adjusted by sliding up and down along the second support 41, so that the revolution track of the moon around the earth in the celestial motion is not only different in distance, but also different in height, and the moon moves on different revolution tracks, and the blocking of the sun is also different, so that the formation process of the three solar eclipse phenomena, i.e. total solar eclipse, annular solar eclipse and partial solar eclipse, is truly presented, so that students can realize that the revolution track of the moon around the earth is not a perfect circle.

[0027] The shapes of the first support 31, the second support 41 and the third support 51 are not particularly limited, and the support shapes capable of achieving equivalent or same effect belong to the protection scope of the utility model.

[0028] As shown in Figure 1 , the simulated earth 05 is provided with an observation hole 52 for observing the cause of solar eclipse.

[0029] The position of the observation hole 52 is not particularly limited, because in reality many coordinates on the earth can observe solar eclipse, but the observation hole 52 is preferably arranged in the upper part of the simulated earth 05, so as to facilitate students to observe the whole process of the formation of solar eclipse phenomenon, and the shape of the observation hole 52 is not particularly limited, and the shape of the observation hole 52 can meet the naked eye observation.

[0030] As shown in Figure 1 , the simulated sun 03 is provided with a simulated lamp 32, the base 01 is further provided with a switch 12 for controlling the simulated lamp 32, and a battery box 13 for installing a battery for supplying power to the simulated lamp 32.

[0031] The simulation lamp 32 is used to simulate the sunlight emitted by the sun 03, and the type and color of the lamp are not particularly limited here. The color is preferably closer to the realistic golden yellow. The switch 12 for controlling the simulation lamp 32 can be provided on the right side or the left side of the base 01. The battery box 13 can also be provided on the right side or the left side of the base 01. The battery box 13 can be a flip type battery box 13 or other battery box 13 with the same effect (such as a drawer type battery box 13). The lid can be opened directly to install the battery. The battery model is not further limited here. The battery is preferably a common and universal battery, such as an AA battery (5# battery) or a AAA battery (7# battery). The process is simple and cost-saving. The simulation lamp 32, the switch 12 and the battery box 13 are electrically connected through wires. The simulation lamp 32 can be turned on by the switch 12.

[0032] As shown in Figure 1 , a solar eclipse formation and lunar orbit reasoning demonstration device also includes a mobile phone holder 06 for holding a mobile phone to shoot the solar eclipse formation through the observation hole 52. The mobile phone holder 06 is provided on the side wall of the base 01 on the same side as the simulated earth 05.

[0033] The mobile phone holder 06 is installed on the front side of the base 01, i.e. on the side wall of the base 01 on the same side as the simulated earth 05, and is located directly below the simulated earth 05. The mobile phone holder 06 has a device for holding a mobile phone. Since there are many models of mobile phones with different sizes, the mobile phone holder 06 is preferably installed through a sliding groove and is preferably rotatable. In this way, the position of the mobile phone can be adjusted by sliding the mobile phone holder 06 up and down to align the camera with the observation hole 52, and the angle can be adjusted by rotating the mobile phone holder 06 to facilitate the alignment of the camera with the observation hole 52. Not only does it solve the difficulty of visual positioning in space observation for students, but it also quickly solidifies the simulated phenomenon through mobile phone shooting, quickly presents evidence to all students for common learning and discussion, and completes the cultivation of core thinking and the achievement of teaching goals.

[0034] As shown in Figure 1 , the background plate 02 is provided with a display plate 21 for displaying the formation process of the solar eclipse.

[0035] The display plate 21 can be hung or attached to the background plate 02, or can be provided with a magnetic attraction device to be attracted to the background plate 02 by magnetic force, or can be connected to the background plate 02 by other methods with the same or similar effect. The display plate 21 can be a light plastic plate or a foam plate or other material, or a display screen. However, from the perspective of safety and cost savings, it is best to use a foam plate.

[0036] The display board 21 is written with the definition of the eclipse, and the continuous photos of the three forms of the eclipse, i.e. the total solar eclipse, the annular solar eclipse and the partial solar eclipse, are arranged in the time sequence of the occurrence of the eclipse, and are provided with the corresponding introduction, so that the students can discuss the celestial law on the display board 21 at any time during the observation, which not only can make the students more easily understand the eclipse phenomenon, but also can mobilize the enthusiasm of the students in learning.
