Description

Technical Field

[0001] This utility model relates to the field of popular science teaching technology, and in particular to a popular science teaching aid for demonstrating electromagnetic radiation. Background Technology

[0002] Electromagnetic radiation is the propagation of momentum and energy in space in the form of waves by electric and magnetic fields that oscillate in the same direction and are perpendicular to each other. The direction of propagation is perpendicular to the plane formed by the electric and magnetic fields. The interaction and change of the electric and magnetic fields produce electromagnetic waves, which are emitted or propagated into the air to form electromagnetic radiation.

[0003] The Crookes radiometer is a tool used for popularizing radiation science. Commonly known as a solar windmill, it is a partially vacuum-sealed glass bulb containing a set of metal blades. When light shines on it, the blades rotate; the stronger the light, the faster they rotate, thus providing a simple quantitative measurement of electromagnetic radiation intensity.

[0004] Currently, popular science education on electromagnetic radiation mainly relies on brochures and videos. However, since electromagnetic radiation is invisible to the naked eye, the public finds it difficult to perceive its existence. Consequently, the abstract data on electromagnetic radiation is not easily understood and lacks intuitive representation, resulting in poor educational effectiveness. Utility Model Content

[0005] To overcome at least one of the shortcomings of the prior art described above, this utility model provides a popular science teaching aid for demonstrating electromagnetic radiation, thereby solving the problem that abstract data on electromagnetic radiation is not easily understood.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A popular science teaching aid demonstrating electromagnetic radiation includes:

[0008] Base;

[0009] The lighting mechanism is slidably connected to the base;

[0010] An electromagnetic radiation sensing mechanism is mounted on a base;

[0011] The display mechanism includes a display panel, a data processor, a distance sensor, a light sensor, and a rotation speed sensor. The rotation speed sensor is mounted on an electromagnetic radiation sensing mechanism, the light sensor is mounted on a base and is used to measure the brightness of the lighting mechanism, and the distance sensor is mounted on the base and is used to measure the distance between the lighting mechanism and the electromagnetic radiation sensing mechanism. The data processor is connected to the distance sensor, the light sensor, and the rotation speed sensor, and the display panel is used to display the data measured by the distance sensor, the light sensor, and the rotation speed sensor.

[0012] The above scheme uses distance sensors, light sensors, and speed sensors to measure data from the lighting mechanism and the electromagnetic radiation sensing mechanism. The data is then processed by a data processor to analyze the relationships between the data and displayed on a panel. This provides a clearer picture of the changes in electromagnetic radiation data and allows for a more detailed understanding of the origins of this data, enhancing knowledge of electromagnetic radiation. This popular science teaching aid provides a highly interactive learning platform, enabling learners to operate and observe the process of electromagnetic radiation data changes firsthand, enhancing public awareness of electromagnetic radiation phenomena in daily life and improving scientific literacy.

[0017] Furthermore, the operating handle is provided with a support rod, the support rod is provided with an indicator head, the base is provided with a scale line on the side facing the operating handle, and the tip of the indicator head faces the scale line.

[0018] With the above-mentioned further solutions, the position of the bulb can be read very intuitively and accurately by using the indicator head and the scale line together. This allows for more precise distance adjustment and recording, which helps to improve the accuracy of experimental data. Users can quickly and easily adjust and confirm the position of the moving rod without additional tools, which not only saves preparation time but also reduces the difficulty of operation.

[0019] Furthermore, the electromagnetic radiation sensing mechanism includes a transparent cover, a vertical rod, a rotating rod, and blades. The transparent cover is fixedly installed on the base, and the vertical rod is fixedly installed on the base and located inside the transparent cover. The upper end of the vertical rod is provided with a groove, and the rotating rod is rotatably connected inside the groove. Multiple evenly arranged horizontal bars are provided on one end of the rotating rod connected to the groove, and the ends of the horizontal bars are connected to blades.

[0020] Through the aforementioned further scheme, by using a rotating rod with blades and installing it in the groove of a vertical rod, the energy of electromagnetic radiation can be intuitively demonstrated by observing the rotation of the blades when electromagnetic radiation acts on them. This intuitiveness is very important for popular science education, as it can transform abstract concepts into phenomena that can be directly observed. Combined with distance and light sensors, the influence of electromagnetic radiation on the rotation speed of the blades under different light intensities or distances can be accurately recorded, which can greatly stimulate learners' interest and increase their enthusiasm for participation.

[0021] Furthermore, the movable rod is equipped with a knob for controlling the brightness of the bulb.

[0022] The above-mentioned further solutions, by directly controlling the brightness of the light bulb on the moving rod, increase the ease of operation and facilitate interactive operation for students.

[0023] Furthermore, the speed sensor is fixedly mounted on the top of the transparent cover and is used to measure the speed of the blades.

[0024] With the above-mentioned further solution, by installing the speed sensor on the top of the transparent cover, the rotational speed of the blades can be monitored directly and accurately. Combined with the data displayed in real time on the display panel, the audience can immediately see the changes in the blade speed, enhancing the interactive experience and teaching effect.

[0025] Furthermore, the light sensor is fixedly mounted on the base, located between the transparent cover and the bulb.

[0026] With the above-mentioned further solution, the light sensor is positioned between the bulb and the transparent cover, which can accurately measure the light intensity emitted by the bulb, reduce interference from external light sources, and ensure the authenticity and accuracy of the measurement results.

[0027] Furthermore, the slide groove is provided with a groove, and the end of the movable rod connected to the slide groove is provided with a protrusion plate. The protrusion plate is slidably connected in the groove, and a distance sensor is fixedly installed on one end of the groove.

[0028] With the above further solution, the distance sensor is fixedly installed at one end of the groove, and the positional change of the moving rod relative to the blade can be directly and accurately measured through the convex plate.
