DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] A teaching aid for simulating the movement of the earth includes a revolution simulation mechanism 1, a rotation simulation mechanism 2 and an earth body 3. The earth body 3 is installed on the revolution simulation mechanism 1. A light source 4 adapted to the earth body 3 is provided on the revolution simulation mechanism 1. The rotation simulation mechanism 2 is connected to the earth body 3 to drive the earth body 3 to rotate.

[0021] The revolution simulation mechanism 1 drives the earth body 3 to revolve around the light source 4 as the center, the rotation simulation mechanism 2 drives the earth body 3 to rotate, and the light source 4 simulates sunlight, so as to more vividly demonstrate the entire process of the earth's movement and improve teaching efficiency.

[0022] The revolution simulation mechanism 1 includes a fixed seat 1-1, a revolution seat 1-2 and a revolution transmission member 1-3. The revolution seat 1-2 is connected to the fixed seat 1-1 through the revolution transmission member 1-3. The earth body 3 is installed on the revolution seat 1-2. The revolution seat 1-2 is driven by the revolution transmission member 1-3 to perform circular motion with the fixed seat 1-1 as the center, thereby realizing the movement of the earth body 3 with the fixed seat 1-1 as the center, realizing the revolution simulation of the earth body 3.

[0023] The revolution transmission member 1-3 includes a rotating rod 1-4 and a pulley group 1-5. The rotating rod 1-4 is rotatably mounted on the fixed seat 1-1, and the revolution seat 1-2 is rotatably mounted on the rotating rod 1-4, that is, the fixed seat 1-1 and the revolution seat 1-2 are respectively located at the two ends of the rotating rod 1-4, and the pulley group 1-5 is respectively connected to the fixed seat 1-1 and the revolution seat 1-2.

[0024] One side pulley of the pulley group 1-5 is fixed on the fixed seat 1-1, and the other side pulley of the pulley group 1-5 is fixed on the revolution seat 1-2. When the revolution seat 1-2 performs a circular motion with the fixed seat 1-1 as the center, the belt of the pulley group 1-5 moves relative to the fixed seat 1-1, thereby driving the pulley on the revolution seat 1-2 to rotate relative to it, so that the earth body 3 rotates relative to the light source 4.

[0025] In order to realize the rotation of the rotating rod 1-4 on the fixed seat 1-1, a revolution drive motor 1-6 is installed on the rotating rod 1-4. The revolution drive motor 1-6 is connected to the fixed seat 1-1 through a gear set 1-7, so that the revolution drive motor 1-6 performs a circular motion along the fixed seat 1-1, thereby driving the rotating rod 1-4 to rotate on the fixed seat 1-1.

[0026] The light source 4 is arranged at the rotation center of the rotating rods 1 - 4 to ensure that the earth body 3 performs a circular motion with the light source 4 as the center.

[0027] The light source 4 includes a wide-width light source 4-1 and a narrow-width light source 4-2. In this embodiment, the wide-width light source 4-1 is a lamp panel structure with a larger width, which is used to generate a wide-width light spot. The narrow-width light source 4-2 is a single-beam light source, which is used to generate a narrow-width light spot. The narrow-width light source 4-2 is arranged in the middle of the wide-width light source 4-1. The wide-width light source 4-1 is used to simulate the earth's polar day and polar night phenomena, and the narrow-width light source 4-2 is used to simulate the direct point of the sun.

[0028] The fixed seat 1-1 includes a base plate 1-12 and a fixed shaft 1-13 connected to the base 1-12. The rotating rod 1-4 is rotatably mounted on the fixed seat 1-13. A solar term indicator is provided on the base plate 1-12. Figure 1 -9, a solar term indicator light 1-8 is provided at the bottom of the rotating rod 1-4, and the solar term indicator light 1-8 indicates the solar term. Figure 1 -9 settings, solar terms indication Figure 1 -9 includes 24 solar term grids evenly distributed on the circumference of the base plate 1-12, and the corresponding solar terms are filled in the solar term grids in the form of pictures and texts. When the rotating rods 1-4 rotate, the solar term indicator lights 1-8 face different solar term grids, thereby displaying the solar terms during the earth's revolution.

[0029] The revolution seat 1-2 includes a revolution shaft 1-10 and an earth mounting plate 1-11 fixedly mounted on the revolution shaft 1-10. The revolution shaft 1-10 is rotatably mounted on the rotating rod 1-4, and the pulley group 1-5 is connected to the revolution shaft 1-10, driving the revolution seat 1-2 to rotate relative to the rotating rod 1-4. The earth body 3 and the rotation simulation mechanism 2 are respectively mounted on the earth mounting plate 1-11.

[0030] The rotation simulation mechanism 2 includes a rotation shaft 2-1 and a rotation motor 2-2. The earth body 3 is installed on the rotation shaft 2-1. The rotation motor 2-2 is connected to the rotation shaft 2-1 to drive the rotation shaft 2-1 to rotate, thereby driving the earth body 3 to rotate.

[0031] An inclined surface 1-14 is provided on the earth mounting plate 1-11, and the rotation axis 2-1 is rotatably mounted on the inclined surface 1-14, so that the rotation axis of the earth body 3 is tilted relative to the rotation center of the rotating rod 1-4, while ensuring that the earth body 3 can rotate on the revolution seat 1-2.

[0032] The outer side of the globe body 3 is wrapped with photochromic material. When the wide light spot and narrow light spot generated by the light source 4 are irradiated on the globe body 3, the color of the surface of the globe body 3 changes, so that the irradiation traces of the light source 4 appear on the globe body 3, making teaching more concrete and improving teaching efficiency.

[0033] This teaching aid includes the following three teaching scenes:

[0034] (1) The north-south movement of the sun's direct point caused by the Earth's revolution;

[0035] The narrow-width light source 4-2 is turned on, the rotating motor 2-2 is in a stopped state, and the rotating rod 1-4 is driven to rotate on the fixed seat 1-1 by the revolution drive motor 1-6, so that the globe body 3 performs a circular motion with the fixed seat 1-1 as the center. Due to the action of the pulley group 1-5, during the circular motion of the globe body 3 along the narrow-width light source 4-2, the globe body 3 rotates relative to the light source, and the photochromic material on the globe body 3 changes, thereby showing the north-south movement of the direct sunlight point on the globe body 3.

[0036] (2) The formation of the Tropic of Cancer and the Tropic of Capricorn;

[0037] The narrow-band light source 4-2 is turned on, and the revolution drive motor 1-6 is in a stopped state. At this time, the rotating rod 1-4 is in a stopped state, and the earth body 3 is driven to rotate by the rotation motor 2-2. The photochromic material on the earth body 3 changes, thereby showing the Tropic of Capricorn or the Tropic of Cancer on the earth body 3.

[0038] (3) The formation of polar day and polar night phenomena;

[0039] The wide-band light source 4-1 is turned on, and the revolution drive motor 1-6 is in a stopped state. At this time, the rotating rod 1-4 is in a stopped state, and the earth body 3 is driven to rotate by the rotation motor 2-2. Since the rotation axis of the earth body 3 is tilted relative to the rotation center of the rotating rod 1-4, part of the earth's surface cannot be illuminated by the wide-band light source 4-1, thereby demonstrating the phenomenon of polar day and polar night.
