[0027] It needs to be further explained that the rotating ring 202 is provided to facilitate driving the hemispherical cover 301 to rotate on the top of the outer base 2 .
[0028] See also Figure 2-5 , the utility model provides the following technical solutions:
[0029] The rotating mechanism 3 includes a hemispherical cover 301, a morning line 302, a dusk line 303, an arc groove 304 and a positioning tube 2 305. The hemispherical cover 301 is arranged on one side of the globe body 1. The morning line 302 is fixedly connected to one side of the hemispherical cover 301. The dusk line 303 is fixedly connected to one side of the hemispherical cover 301. An arc groove 304 is opened on the lower surface of the hemispherical cover 301.

[0030] The photosensitive mechanism 4 includes a photosensitive paper 401, a fixed axis 1 402, a connecting plate 403 and a fixed axis 2 404. The photosensitive paper 401 is rotatably connected to one side of the globe body 1. The fixed axis 1 402 is arranged on the lower surface of the globe body 1.

[0031] The hemispherical cover 301 is rotatably connected to the top of the outer base 2 , and the second positioning tube 305 is movably inserted into the interior of the fixed sleeve 204 .
[0032] The photosensitive paper 401 is rotatably connected to the outer surface of the connecting rod 101, and the fixed shaft 402 is movably inserted into the interior of the positioning tube 103.
[0033] The fixed shaft 1 402 is fixedly inserted at the bottom of the connecting rod 101 , and the fixed shaft 2 404 is movably inserted inside the positioning tube 1 103 .
[0034] What needs to be further explained is that: by setting up a rotating mechanism 3, it is convenient to display the day and night conditions on the earth during the solar term. A photosensitive mechanism 4 is set on one side of the globe main body 1. By setting up the photosensitive mechanism 4, it is convenient to observe the day and night conditions on the globe by turning on the white light, and then switching to ultraviolet light to irradiate the globe at the right time. The photosensitive area where the ultraviolet light is directly irradiated has the darkest color, and the photosensitive area where the ultraviolet light is obliquely irradiated has a lighter color. This can not only display the position of the direct point, but also simulate the different temperature conditions of the direct area and the oblique area, so as to understand the reasons for the different temperatures in different seasons.
[0035] Working principle: When a device for simulating the causes of four seasons with alternating day and night is used, first, the globe body 1 is arranged on the top of the outer base 2 through the connecting rod 101, the inner base 102 and the positioning tube 103, and a rotating mechanism 3 is arranged on one side of the globe body 1. The rotating mechanism 3 is arranged to facilitate the display of the day and night conditions on the earth during the solar term, and a photosensitive mechanism 4 is arranged on one side of the globe body 1. The photosensitive mechanism 4 is arranged to facilitate the observation of the day and night conditions on the globe by turning on white light, and then switching to ultraviolet light to irradiate the globe at the right time. The color of the photosensitive area where the ultraviolet light is directly irradiated is the darkest, and the color of the photosensitive area where the ultraviolet light is obliquely irradiated is lighter, so that the position of the direct point can be displayed, and the different temperature conditions of the direct area and the oblique area can be simulated, so as to understand the reasons for the different temperatures in different seasons;
[0036] When it is necessary to observe the day and night conditions on the earth, first, the hemispherical cover 301 is set as a black-gray transparent hemispherical body. The hemispherical cover 301 is set on one side of the globe body 1 to simulate the night hemisphere area of the earth. A morning line 302 and a dusk line 303 are set on both sides of the hemispherical cover 301 to simulate the real morning and dusk lines. A second positioning tube 305 is set at the bottom of the hemispherical cover 301. The second positioning tube 305 is plugged into the top of the fixed sleeve 204. The second positioning tube 305 is used to drive the hemispherical cover 301 to rotate on the outer surface of the globe body 1. The device is convenient for observing the day and night conditions on the earth.
[0037] When it is necessary to observe the seasonal temperature conditions on the earth, firstly, by setting the photosensitive paper 401, the simulated earth and the simulated night hemisphere (the day hemisphere faces the sun) are placed in the appropriate position of the spring, summer, autumn and winter, and the white light is turned on to observe the day and night conditions on the globe. Then, the ultraviolet light is switched to illuminate the globe at the appropriate time. The photosensitive area where the ultraviolet light is directly irradiated has the darkest color, and the photosensitive area where the ultraviolet light is obliquely irradiated has a lighter color, so that the position of the direct point can be displayed, and the temperature of the direct area and the oblique area can be simulated, so as to understand the different reasons for the different temperatures in different seasons. When the hemispherical cover 301 rotates, the solar term indicating rod 203 rotates accordingly. At this time, the indicating arrow 104 fixedly connected to one side of the positioning tube 103 points to the solar term indicating rod 203, which is convenient for observing the solar terms. The device is convenient for observing the seasonal temperature conditions on the earth.
