Description

A Simple Solar Altimeter

technical field

The utility model relates to the technical field of middle school geography teaching aids, in particular to a simple solar altimeter.

Background technique

In middle school geography teaching, the sun's altitude angle is both an important point and a difficult point. Simply drawing pictures on the blackboard to explain is too abstract for students to understand. The altitude angle of the sun refers to the angle between the sun's rays and the earth's surface. Someone proposed a solar altimeter measuring instrument, comprising a support plate and a base, the support plate is fixed on the base, a vertical scribe line is provided at the middle position of the surface of the support plate, and an instrument panel is provided on the support plate, The instrument panel is provided with a scale value, the instrument panel is provided with a pointer, the two ends of the pointer are provided with vertical parts perpendicular to the pointer, and the vertical parts at both ends of the pointer are provided with light holes , the centers of the two light holes are located on the same axis, the two ends of the pointer are respectively provided with reading holes, and the pointer is rotatably connected with the instrument panel and the support plate. Although this solar altitude measuring instrument can measure the size of the solar altitude angle, its structure is complicated and its production cost is high, which is not conducive to popularization and popularization in vast middle schools, and it is inconvenient to use and not accurate enough to measure because it needs to turn the pointer when using it. .

Utility model content

The purpose of the utility model is to provide a simple solar altimeter with low cost, easy operation and accurate demonstration effect in view of the disadvantages of the existing simple solar altimeter such as high cost, complicated operation and inaccurate demonstration effect.

The purpose of this utility model is achieved by the following technical means: a simple solar altimeter, including a base, a pole, a weight line, a weight, a protractor plate is connected to the pole, and the The protractor plate is connected to the support bar through an arc-shaped frame; the weight and weight line are connected to the protractor plate through a vertical rotation shaft; the support rod is connected to the base through a horizontal rotation shaft.

The arc frame and the protractor plate are set as thin plates.

The base and the pole are configured as cylinders.

Compared with the prior art, the utility model has the following obvious advantages: the simple solar altimeter can be adjusted easily and conveniently, and can better demonstrate and measure the altitude angle of the sun, thereby calculating the solar altitude; The overall instrument uses less materials, saves costs, and is easy to carry and handle, which is beneficial to classroom demonstrations.

Description of drawings

Fig. 1 is the structural representation of the utility model;

In the figure, 1-vertical shaft, 2-protractor plate, 3-arc frame, 4-weight, 5-rod, 6-flat shaft, 7-base.

Detailed ways

Below in conjunction with accompanying drawing description and specific embodiment, the utility model is described in further detail:

A kind of simple solar altimeter as shown in Figure 1, comprises base 7, strut 5, weight line, weight 4, and described strut 5 is connected with protractor plate 2, and described protractor plate 2 is connected to the support rod 5 through the arc frame 3; the weight 4 and the weight line are connected to the protractor plate 2 through the vertical rotation shaft 1; the support rod 5 is connected to the base through the horizontal rotation shaft 6 7 on. In this way, when the simple sun altimeter is used in practice, the position of the protractor plate 2 is adjusted by rotating the vertical shaft 1, so that when the weight line coincides with the 90° scale line of the angle indicating scale on the protractor plate 2, it indicates that the base 7 is in a horizontal state, then rotate the horizontal axis 6 to adjust the base 1, and by observing the position of the weight 4, the base 7 is always in a horizontal state, so that the projection of the weight line just falls on the protractor plate 2, at this time, the projection The scale indicated is the solar altitude angle. Then calculate the solar altitude value; this simple solar altitude measuring instrument uses less materials overall, saves costs, and is easy to carry and put down, which is beneficial for classroom demonstrations.

The arc-shaped frame 3 and the protractor plate 2 are set as thin plates. Arranged like this, the overall design of the utility model is relatively light and handy, simple and convenient, can adjust operation easily, demonstrates preferably and measures the altitude angle of the sun.

The base 7 and the pole 5 are configured as cylinders. Such arrangement further saves the materials of the utility model and enhances the flexibility of the utility model operation.

In a word, the utility model provides a simple solar altimeter with low cost, simple operation and accurate demonstration effect. The above is only a part of the specific implementation methods of the utility model, and the protection scope of the utility model is not limited thereto. Any skilled person familiar with the technical field can easily think of changes within the technical scope disclosed in the utility model Or replacement, all should be covered within the scope of protection of the present utility model.
