Description

Model for earth rotation and revolution Technical Field The utility model relates to an earth rotation and revolution model. Background The rotation and revolution of the earth are important knowledge points in the geographical discipline, and the prior teaching mainly depends on the oral explanation of a teacher or the explanation of a wall map, but the rotation and revolution of the earth cannot be reproduced in an image, the day and night alternation and the seasonal variation cannot be reproduced in an image, the teaching is monotonous and boring, and the enthusiasm of students cannot be actively mobilized, so that the teaching effect is poor. Disclosure of utility model The utility model improves the problems, namely the technical problem to be solved by the utility model is to provide the earth rotation and revolution model which can vividly demonstrate the rotation and revolution of the earth, so that the teaching is vivid, the learning interest of students is increased, and the teaching quality is ensured. The solar energy simulation lamp comprises a workbench and a large turntable rotatably arranged on the workbench, wherein a solar energy simulation lamp is arranged in the middle of the large turntable, a small turntable is arranged at the edge of the large turntable, the small turntable is in rotary fit with the large turntable, and a globe assembly is arranged on the small turntable. Further, the large turntable comprises a lower large turntable body and an upper rotating body sleeved on the lower large turntable body, the upper rotating body is in running fit with the lower large turntable body, a flat plate is arranged on the upper rotating body, and a supporting body is arranged below the lower large turntable body. Further, the small turntable comprises an upper rotating body and a lower small turntable body, wherein a rotating shaft is arranged in the middle of the lower small turntable body, and the rotating shaft is in running fit with the upper rotating body. Further, the globe assembly comprises a mounting seat arranged on the small turntable, a globe is arranged above the mounting seat, a fixed shaft is arranged in the middle of the globe in a penetrating way, the lower part of the fixed shaft is connected with an output shaft of a motor arranged in the mounting seat, and a shadow measuring sign is arranged on the outer side of the globe. Furthermore, the globe is obliquely arranged, the corresponding fixed shaft and motor are obliquely arranged, and the upper surface of the mounting seat is an inclined surface. Furthermore, the globe is vertically arranged, the corresponding fixed shaft and motor are also vertically arranged, and the upper surface of the mounting seat is a horizontal plane. Further, the flat plate is connected with the solar simulation lamp through the upright post. Further, balls are arranged between the upper rotating body and the lower large disc body. Further, four-season photo paper is arranged between the workbench and the large turntable, and the upper part, the left part, the lower part and the right part of the four-season photo paper are respectively provided with spring, summer, autumn and winter marks. Furthermore, a north pole direction mark is arranged on the right side of the winter mark, and an arrow mark is arranged on the upper surface of the small turntable and can always point to the north pole direction mark. The utility model has the advantages that the device has simple structure and reasonable design, is convenient to use, can vividly demonstrate the rotation and revolution of the earth, enables teaching to be vivid and image, increases the learning interest of students, ensures the teaching quality, and is worthy of explanation that the motor of the small turntable is opened by installing the globe assembly on the small turntable, the globe on the small turntable is driven to rotate by the motor, the sun simulation lamp is arranged on the upright post in the center of the large turntable, the small turntable is pressed to drive the large turntable to rotate, thereby simulating the phenomena of rotation and revolution, the arrow mark on the small turntable is ensured to point to the identification direction of the arctic star, the toothpick is inserted on the globe, and a graduated scale is stuck on the globe, and the arrow mark direction of the small turntable is adjusted to point to the identification direction of the arctic star when the revolution reaches Ji Jiedian, and the change rule of the shadow length is found by observing the shadow length of the toothpick.
