Problems solved by technology

[0003] In the existing technology, the teaching of sunshine projection mostly adopts the PPT graphic method, and two circles are used to represent the sun and the earth respectively. Draw the projected area on the earth. This method is a static diagram. It lacks a three-dimensional and dynamic sunshine projection relationship display. It is difficult for students to understand.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments, but it should be understood that the protection scope of the present invention is not limited by specific embodiments.

[0023] A kind of multifunctional geographical sunshine projection teaching experimental device, such as figure 1 As shown, it includes the base 1, the sun model and the earth model. The base 1 is made of a flat plate or other flat boards. The function of the base 1 is to bear the weight of the entire sunshine projection teaching experiment device and make the device easy to move. In order to facilitate the mobile device, universal wheels can also be installed on the bottom of the base 1; a longitudinal support rod 2 is fixedly installed on the base 1 or on the upper surface of the base 1, and a rotatable earth orbit 3 is installed on the longitudinal support rod 2. The shape of the orbit 3 simulates the orbit shape of the earth orbiting the sun, which is ...

Abstract

The invention belongs to the technical field of teaching devices, and particularly relates to a multifunctional geographic sunshine projection teaching experiment device. The device comprises a base,a sun model and an earth model; a longitudinal supporting rod is fixedly installed on the base; a rotatable earth motion orbit is installed on the longitudinal supporting rod; the shape of the earth motion orbit simulates the orbit shape of the earth moving around the sun; the sun model comprises a light scattering and emitting body, a longitudinal rotating ring, a transverse rotating ring, a linear light source and a light source supporting column; the earth model is installed on the earth motion orbit in a sliding mode; and the earth model not only can slide along the earth motion orbit, butalso can simulate real earth rotation. According to the device, not only the real process that the earth moves around the sun, but also the sunshine projection can be simulated; and the three-dimensional and dynamic effects are added.

Description

technical field [0001] The invention belongs to the technical field of teaching devices, and in particular relates to a multifunctional geographical sunshine projection teaching experiment device. Background technique [0002] Sunshine projection is a common course in geography teaching. We know that the rotation direction of the earth is counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Different locations on the earth receive different angles of sunlight, so different projections will appear. Correctly interpret these projections It can help students understand the sunshine relationship between the earth and the sun in time. In daily life, due to the different heights of buildings on the earth, when the angle of sunlight changes, the size of the projection of the building will also change accordingly. Grasping the relationship between the projection of buildings and the angle of sunlight will have a great impact on urban planning and arc...
