Application method of the utility model

And determining time according to the position relation between the earth, the sun and the moon. The direction is determined from the warp and weft. When the moon is observed while standing on the earth, the lunar phase changes due to the change in the spatial position among the moon, the earth and the sun. The work adopts a mode of combining a drawing board and a real object to enhance the space perception, visually observe the moon phase change and understand the moon phase cause.

1. The sun instrument is arranged at the sunlight position on the right side of the drawing board.

2. The moon is placed at any position of the orbit of the moon around the earth of the drawing board. Moon gauges are divided into black and white. The white face faces the sun meter and represents the illuminated part of sunlight; the black surface faces away from the sun meter and represents the part which cannot be illuminated by the sun.

3. The direction of the objective lens of the observer is aligned with the moon, and the ocular lens is used for observing the moon phase. The direction of the objective lens points to the south along the meridian, and accords with the characteristic of 'north from top to bottom and right from left to right' of a starry sky.

4. The observer can rotate to observe the moon shape of lunar calendar on different dates.

5. The time azimuth disc is matched with the map board map.

The red line is a "time pointer" pointing to time on the drawing board, again indicating the direction south. The black lines indicate the east-west direction.

When the direction of the objective lens of the observer is consistent with the direction of the time pointer, the corresponding time is when the moon of the current day is positioned in the sky in the south. In the case of the upper moon, the time when we see the moon in the sky right in the south is about 18 hours. When the time is full of the month, we see in the sky right in the south that the moon time is around 0.

The time azimuth disk is rotated (as the earth rotates, the time azimuth disk also rotates), the time pointer indicates the observation time, and the moon azimuth is the direction of the objective lens direction of the observer on the time azimuth disk. In the case of the upper lunar, the moon is in the eastern state at 12 and in the western state at 0, and the moon can be seen in the first half of the night. When the moon is full, the moon is in the eastern state at 18 times and in the western state at 6 times, and the moon can be seen in the whole night. If the sun, earth, moon are well in line, then lunar eating may occur. In the lower meniscus, the moon is in the eastern direction at 0 and in the western direction at 12, and the moon can be seen only in the latter half of the night. In the case of a new moon, the moon is facing away from the earth, the moon cannot be seen in the daytime, and the moon cannot be seen at night. If the sun and moon are well aligned during the new month, the phenomenon of solar eclipse occurs.

The utility model has the meaning that

1. The lunar phase calendar has the advantages that the lunar phases of different dates of the lunar calendar can be visually and clearly seen, and the lunar phase causes can be more vividly understood; the change in the lunar phase is due to the change in the positional relationship among the earth, moon and sun. The viewing angle is changed and the visual effect is also changed. 2. The mode of combining the drawing board with the real object is adopted, so that the spatial third dimension is enhanced. The color map has a space concept, and the three-dimensional effect of the object is overlapped with the space position direction of the drawing board, so that the space three-dimensional sense is enhanced. 3.

The moon shape is seen, the time is known, and the direction can be judged; the moon shape is seen, the direction is known, and the time can be estimated. Theoretical knowledge and life reality are combined, students can pay attention to geographical phenomenon around, and the teaching aid has a heuristic reference effect for professional teachers and related personnel. 4. The process is exquisite and the demonstration operation is flexible. The demonstration instrument can flexibly display the moon phase condition at any time, and the manufacturing process is also exquisite. The operation is flexible, and the manual operation and the electric demonstration can be realized. 5. Local materials are available, the manufacturing cost is low, the price is low, and the method is convenient to popularize.
