Description

Technical Field

[0001] This invention relates to the field of astronomy, and in particular to an experimental apparatus and method for simulating the luminosity changes of eclipsing binary stars. Background Technology

[0002] Astronomical simulations of the luminosity changes of eclipsing binary stars are of great significance. An eclipsing binary star system refers to stars that pass each other in the direction of the observer's line of sight. During this process, one star blocks part or all of the light from the other star, causing a change in luminosity. The study of this phenomenon is very important for our understanding of the properties of stars, the evolution of galaxies, and the physical processes of the universe.

[0003] In existing technologies, physical models and experimental equipment are used to simulate the luminosity changes of eclipsing binary stars. To obtain different data, different diameter, light-transmitting, hollow spheres (referred to as light source spheres) are used to simulate the stars. During the fixation of the light source spheres, different fixing clamps are required for different spheres. Frequent clamp changes make the device very cumbersome and complex to use, increasing the workload. Based on this, we hereby provide an experimental device and method for astronomically simulating the luminosity changes of eclipsing binary stars to solve such problems. Summary of the Invention

[0039] Example 1

[0040] Reference Figures 1-3 This is the first embodiment of the present invention, which provides an experimental apparatus for simulating the luminosity changes of eclipsing binary stars in astronomy, comprising:

[0041] The fixed unit 100 includes a support member 101 located at the bottom, an angle display member 102 disposed at the top of the support member 101, a length display member 103 horizontally disposed on the angle display member 102, and a limiting member 104 disposed on the angle display member 102, wherein the limiting member 104 connects the angle display member 102 and the length display member 103 in series. The angle display member 102 is fixedly connected to the top of the support member 101, and the length display member 103 is horizontally rotatably connected to the angle display member 102, enabling vertical angle adjustment on the angle display member 102. The limiting member 104 connects the angle display member 102 and the length display member 103, allowing the length display member 103 to rotate on the angle display member 102 with the limiting member 104 as the center, thereby achieving the purpose of adjusting the rotation angle.

[0042] The limiting unit 200 includes a fixing component 201 located on the length display component 103, an adjusting component 202 disposed below the fixing component 201, an adjusting component 203 disposed inside the fixing component 201, and a positioning component 204 disposed above the fixing component 201. Two sets of limiting units 200 are symmetrically arranged on the length display component 103, and two simulated light sources for simulating binary eclipses are installed on the two sets of limiting units 200. The fixing component 201 can slide on the length display component 103 to adjust the distance between the two sets of limiting units 200. The adjusting component 202 is threadedly connected to the lower part of the fixing component 201, the adjusting component 203 is threadedly connected to the inside of the fixing component 201, the outer side of the positioning component 204 is slidably connected to the upper part of the fixing component 201, and the top end of the positioning component 204 is rotatably connected to the top end of the adjusting component 203.

[0043] During use, according to actual needs, a suitable simulated light source is selected and fixed on the fixed component 201 via the positioning component 204. The distance between the two sets of limiting units 200 is adjusted by sliding on the length display component 103. By rotating the adjustment component 202, the limiting unit 200 can be fixed at a specified position on the length display component 103. Through the above operations, the distance between the two sets of simulated light sources can be adjusted to meet more experimental needs. Subsequently, according to the needs, the angle of the length display component 103 on the angle display component 102 is adjusted, and the length display component 103 is fixed at a specified angle by rotating the limiting component 104 to obtain experimental data on the width transformation of eclipsing binary stars at different angles, thus meeting more usage needs.

[0044] The support component 101 includes a base 101a at the bottom, a drive motor 101b above the base 101a, and a support rod 101c above the drive motor 101b. An angle display component 102 is located at the top of the support rod 101c. The base 101a is the overall support base of the device. The support rod 101c is connected to the drive motor 101b. Driven by the drive motor 101b, the angle display component 102 and the length display component 103 can rotate in a circle to simulate the rotation of a planet. The support rod 101c is a telescopic adjustment rod, which can adjust the support height according to the usage requirements to meet more usage needs.

[0045] The angle display component 102 includes an angle display block 102a located at the top of the support rod 101c, a connecting shaft 102b located at the center of the angle display block 102a, and angle scales 102c on both sides of the angle display block 102a. The angle display block 102a has a semi-circular structure, and the connecting shaft 102b at its center is used to fix the limiting component 104. The limiting component 104 is threadedly connected to the connecting shaft 102b. The angle scales 102c cooperate with the angle display block 102a to form a protractor structure. The length display component 103 is set on the angle display component 102. The center positions of the angle display component 102 and the length display component 103 coincide. Therefore, when the length display component 103 rotates, the rotation angle can be accurately displayed on the angle display component 102. The intuitive display of the angle scales 102c makes it convenient for experimental personnel to record data and obtain more experimental data.

[0046] The length display component 103 includes a length display rod 103a located on the angle display block 102a, a sliding groove 103b formed between the length display rods 103a, length scales 103c distributed on both sides of the length display rods 103a, a limiting groove 103d located at the center of the length display rods 103a, display grooves 103e located on the length display rods 103a and on both sides of the limiting grooves 103d, and an angle pointer 103f located in the display grooves 103e. The limiting component 104 is rotatably connected to the length display component 103 through the limiting grooves 103d.

[0047] Furthermore, the fixed component 201 is slidably limited within the slide groove 103b, and the length scale 103c can accurately and intuitively record the distance the fixed component 201 moves on the length display component 103, facilitating data recording by experimental personnel. The display slot 103e is used to install the angle pointer 103f, which is parallel to the right-angle side of the angle display component 102. When the length display component 103 rotates, the angle pointer 103f will rotate on the angle display component 102 and indicate the angle scale 102c at the specified angle, intuitively displaying the rotation angle of the length display component 103. The limiting groove 103d overlaps with the connecting shaft 102b and is the center of the length display component 103.

[0048] The limiting component 104 includes a limiting shaft 104a located within the connecting shaft 102b, with the limiting shaft 104a passing through the limiting groove 103d and the connecting shaft 102b in sequence, a knob 104b disposed at one end of the limiting shaft 104a, a pressure plate 104c disposed on the limiting shaft 104a, and a pressure piece 104d disposed at the other end of the limiting shaft 104a. The limiting shaft 104a is threadedly connected to the connecting shaft 102b, and the pressure plate 104c is located within the slide groove 103b and matches and overlaps with the slide groove 103b.

[0049] During use, the limiting unit 200 slides along the slide groove 103b on the length display component 103. The length scales 103c on both sides of the length display component 103 can intuitively record the distance the limiting unit 200 has moved. Then, as needed, the length display rod 103a is rotated with the center of the circle where the angle display component 102 and the length display component 103 coincide as the axis. The angle pointer 103f set on the length display rod 103a will rotate with the length display rod 103a and can indicate the angle scale 102 on the angle display component 102 while rotating. c. The overall rotation angle range of the length display component 103 is displayed intuitively, so that while the angle is adjusted, it is convenient for the staff to record data. Then, the limiting component 104 is rotated, and the limiting shaft 104a moves along the connecting shaft 102b through the threaded connection with the connecting shaft 102b. The moving limiting component 104 drives the pressure plate 104c to move in the limiting groove 103d, and finally presses the length display rod 103a close to the connecting shaft 102b, thereby fixing the length display component 103 on the angle display component 102.

[0050] Example 2

[0051] Reference Figures 4-8 This is the second embodiment of the present invention, which differs from the first embodiment in that it provides a measure to fix simulated light source covers of different sizes, thereby improving the installation efficiency of simulated light source covers.

[0052] Compared to Embodiment 1, the fixing component 201 further includes a fixing disk 201a located in the slide groove 103b, a threaded shaft 201b disposed below the fixing disk 201a, and scale pointers 201c disposed below the fixing disk 201a and located on both sides of the threaded shaft 201b. The threaded shaft 201b is fixedly connected to the lower part of the fixing disk 201a, and the scale pointers 201c are fixedly connected to the lower sides of the fixing disk 201a. When the threaded shaft 201b is inserted into the slide groove 103b, the fixing disk 201a is located above the length display rod 103a, and the scale pointers 201c on both sides are respectively engaged with the outer side of the length display rod 103a, and the lower part of the scale pointers 201c is aligned with the length scale 103c.

[0053] Furthermore, a moving groove 201a-1 for sliding and limiting the positioning component 204 is provided above the fixed plate 201a, and a threaded hole 201b-1 is provided inside the threaded shaft 201b. The adjusting component 203 is threadedly connected to the threaded hole 201b-1 and can move vertically inside the threaded shaft 201b by the drive of the thread.

[0054] During use, the length scale 103c is evenly and symmetrically distributed at both ends of the length display rod 103a with the center of the length display rod 103a as the origin. When the limiting unit 200 on one side moves on the length display component 103, the fixing component 201 slides along the slide groove 103b. The distance it moves on the length display component 103 is from the origin position to the scale position indicated by the scale pointer 201c. The same applies to the other side. In this way, the distance moved by the limiting unit 200 can be obtained intuitively and effectively, so as to better grasp the experimental data.

[0055] Furthermore, the simulated light source is a spherical dome with good transparency. The dome has an opening at the bottom for fixing it. In the prior art, the dome is fixed by the opening. At the same time, the size of the opening at the bottom is different for domes of different sizes.

[0056] The adjusting component 202 includes an adjusting rudder 202a located on a threaded shaft 201b, limiting rings 202b disposed on the upper and lower sides of the adjusting rudder 202a, and a threaded groove 202c opened in the adjusting rudder 202a, with the threaded groove 202c passing through the adjusting rudder 202a and the limiting rings 202b. The adjusting rudder 202a is threadedly connected to the threaded shaft 201b, which passes through the scale pointer 201c. Rotating the adjusting rudder 202a can drive the adjusting component 202 to move along the threaded shaft 201b. If it moves upward, the adjusting component 202 can clamp and fix the limiting unit 200 at any position on the length display component 103 through the mutual pressing and cooperation between the limiting rings 202b and the fixed plate 201a. Conversely, if it moves downward, the clamping on the length display component 103 is released, and the limiting unit 200 is in a free state.

[0057] The adjusting component 203 includes a threaded rod 203a located within the fixing component 201, an adjusting knob 203b located at the end of the threaded rod 203a, and a limiting piece 203c located at the top of the threaded rod 203a. The threaded rod 203a is threadedly connected to the threaded hole 201b-1. The adjusting knob 203b and the limiting piece 203c are respectively fixedly connected to both ends of the threaded rod 203a, and the limiting piece 203c extends into the positioning component 204. The threaded rod 203a is rotatably limited and connected to the positioning component 204 through the limiting piece 203c.

[0058] The positioning component 204 includes a top component 204a located at the top of the threaded rod 203a, three sets of connecting rods 204b disposed on the outside of the top component 204a, and a fixing component 204c disposed at one end of each set of connecting rods 204b. The top component 204a is rotatably limited to the top of the adjusting component 203 and can move vertically with the adjusting component 203. The connecting rods 204b are rotatably connected between the top component 204a and the fixing component 204c. The fixing component 204c is slidably connected in the moving groove 201a-1 below.

[0059] Furthermore, the top assembly 204a includes a top block 204a-1 rotatably connected to the adjustment component 203, a light source body 204a-2 disposed at the top of the top block 204a-1, and a connecting ear 204a-3 disposed on the outside of the top block 204a-1 for rotatably connecting with the connecting rod 204b. The light source body 204a-2 is used to provide a light source for emitting light, and its brightness can be freely adjusted according to needs.

[0060] Furthermore, the fixing component 204c includes a vertically arranged fixing shaft 204c-1, a pad 204c-2 disposed on the outer side of the top of the top block 204a-1, a slider 204c-3 disposed horizontally at the lower end of the fixing shaft 204c-1, and a fixing lug 204c-4 disposed on the side of the fixing shaft 204c-1 and rotatably connected to the connecting rod 204b. The slider 204c-3 has a rectangular structure and is slidably disposed in the moving groove 201a-1. Due to its rectangular structure, the slider 204c-3 can only slide parallel within the top block 204a-1. The fixing shaft 204c-1 is perpendicular to the slider 204c-3. Therefore, the fixing shaft 204c-1 cannot bend when the slider 204c-3 moves and can only maintain an upright position. The pad 204c-2 is made of a soft material to prevent damage to the lampshade.

[0061] During use, the fixing range of the positioning component 204 can be adjusted by rotating the adjusting component 203, according to the size of the lampshade and the actual size of the lampshade opening. By adjusting the knob 203b to rotate the threaded rod 203a, the threaded rod 203a, through its threaded connection with the threaded shaft 201b, will move vertically on the fixing component 201. When the threaded rod 203a moves downward, the adjusting component 203 will drive the top component 204a to move downward. The downward-moving top component 204a will push the fixing component 204c outward through the connecting rod 204b, causing the three sets of fixing components 204c on the outside to expand outward synchronously. The entire assembly, limited by slider 204c-3, will slide outward along the moving groove 201a-1 in a vertical state. The sliding fixing component 204c will eventually abut against the edge of the simulated light source's cover. The three sets of fixing components 204c move in the same way, ultimately fixing the simulated light source firmly to the fixing component 201. The positioning component 204 can be freely opened and closed, achieving the purpose of fixing simulated light source covers of different sizes. Conversely, the adjusting component 203 drives the top component 204a to retract downward, and the fixing component 204c will retract inward, thereby releasing the simulated light source from its limitation or changing the clamping and fixing range to meet more usage needs.

[0062] The remaining structure is the same as that in Example 1.
