Description

Technical Field

[0001] The present invention relates to the technical field of physics teaching aids, and particularly to a device for demonstrating physical light refraction experiments. Background Art

[0002] Physics light refraction experiment demonstration teaching aids are teaching tools used to display the refraction phenomenon of light in different media. It usually includes a transparent refraction cover, such as a hemispherical or square shape, for containing refraction media, such as water or glass. A light beam generated by a light source (such as a laser pointer or a white light source) can be projected into the transparent cover and refracted in different media through optical principles. There are usually scale rulers on the teaching aids for measuring and recording the refraction angle of the light so that observers can quantitatively analyze the experimental results. In addition, the experimental platform ensures the stable placement of the teaching aids, and an oscilloscope or a camera can project the experimental process onto a screen for clearer observation and analysis. Through these teaching aids, students can intuitively understand the refraction law of light in different media and deepen their understanding of optical principles.

[0003] After retrieval, the invention patent with the Chinese patent number CN106023754B discloses a teaching demonstration device for light refraction, including a support base, a demonstration panel arranged on the support base, a light source assembly, a light source assembly fixing member, a dial, and a refraction assembly. The light source assembly, the light source assembly fixing member, the dial, and the refraction assembly are all arranged on the demonstration panel. The demonstration panel is also provided with a semi-circular track, fixing holes, and a sliding groove capable of horizontally moving the dial. The dial is semi-circular and arranged above the refraction assembly. The length of the semi-circular track in the horizontal direction and the height in the vertical direction are both greater than the maximum diameter of the dial. A light source assembly fixing member capable of fixing the light source assembly is arranged outside the light source assembly. The light source assembly fixing member is arranged on the semi-circular track and can move along the semi-circular track.

[0004] Compared with the prior art, the invention patent with the Chinese patent number CN106023754B can adjust the incident angle of the light source assembly. After the light source irradiates, the angle of the dial can be adjusted by rotating the adjustment handle of the dial, so that the angle at which the light source irradiates the incident window can be directly read through the dial, ensuring the accuracy of the experimental effect, improving the learning initiative, and ensuring that the teaching is vivid and interesting.

[0005] However, during the actual use of the above-mentioned device, the indoor lighting environment is likely to affect the students' actual observation, which is inconvenient for students with myopia or sitting at the back to observe. In addition, when conducting refraction experiments on liquids, the light often passes through the transparent container containing the liquid first, which will affect the refraction angle, making it difficult to meet existing needs. Therefore, a physical light refraction experiment demonstration device is proposed, which can provide a visual environment for the light path and can conduct refraction experiments on different liquids. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art that the indoor lighting environment can easily affect the actual observation of students, which makes it inconvenient for students with myopia or sitting at the back to observe, and when conducting a refraction experiment on liquid, the light often passes through the transparent container containing the liquid first, which will affect the refraction angle. A device for demonstrating physical light refraction experiments is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A device for demonstrating a physical light refraction experiment comprises an L-shaped plate, an observation chamber, a scale plate and a liquid refilling chamber, wherein the liquid refilling chamber is fixedly connected to a liquid storage chamber on the outside, and the observation chamber, the liquid refilling chamber and the liquid storage chamber are combined into a liquid medium circulation mechanism, wherein the liquid medium circulation mechanism comprises a receiving channel fixedly connected to the outside of the liquid refilling chamber, a liquid outlet channel fixedly connected to the outside of the liquid storage chamber, a cross valve movably connected to the inside of the liquid refilling chamber and a booster pump fixedly connected to the outside of the liquid storage chamber, and the observation chamber, the scale plate and the L-shaped plate together constitute an auxiliary observation mechanism, wherein the auxiliary observation mechanism comprises a water storage chamber fixedly connected to the outside of the L-shaped plate, a circulation pump fixedly connected to the outside of the L-shaped plate, a condensate chamber fixedly connected to the outside of the L-shaped plate, an atomizing nozzle fixedly connected to the inside of the observation chamber and a collecting fan fixedly connected to the inside of the observation chamber, the L-shaped plate is fixedly connected to a support frame on the outside, an adjusting bearing is fixedly connected to the outside of the support frame, and a reflector is fixedly connected to the outside of the scale plate.

[0009] The above technical solution further includes:

[0010] A connecting ring is fixedly connected to the inside of the liquid replenishing tank, a sealing gasket is fixedly connected to the outside of the cross valve, a connecting groove is opened on the outside of the cross valve, a driven gear column is fixedly connected to the outside of the cross valve, an active gear column is fixedly connected to the end of the booster pump transmission shaft, a transmission belt is movably connected to the outside of the driven gear column and the active gear column, and a protective cover is movably connected to the outside of the driven gear column and the active gear column. When conducting a liquid refraction experiment, the relevant liquid medium is injected into the liquid storage tank, and the inside of the liquid storage tank is pressurized by the booster pump and transmitted through the liquid outlet channel and transmitted to the inside of the receiving channel through the air. In this process, the liquid medium forms a laminar flow under the action of the liquid outlet channel and forms a rectangular shape under the shaping of the outlet of the liquid outlet channel, which is convenient for the laser pen to pass through the medium for refraction. The liquid medium received by the receiving channel is stably input into the liquid storage tank under the drive of the cross valve to prevent the pressure inside the liquid storage tank from fluctuating violently, so that the laminar flow formed by the liquid medium circulates stably.

[0011] The water storage bin, the circulation pump, the atomizing nozzle, the collecting fan and the condensation bin are all connected by a connecting pipe. A condensation column is fixedly connected to the inside of the condensation bin, and a buffer sponge is movably connected to the inside of the condensation bin. When conducting refraction experiment observations, if the indoor light environment is strong or the distance is far, the water inside the water storage bin is atomized by the atomizing nozzle through the circulation pump and then fills the inside of the observation bin, thereby enhancing the Tyndall effect of the laser passing through the water mist inside the observation bin, and is recovered through the collecting fan and liquefied through the condensation bin, thereby greatly improving the observation effect of the device.

[0012] The receiving channel is fixedly connected to the observation chamber, the liquid outlet channel is fixedly connected to the observation chamber, the connecting ring is movably connected to the connecting groove, the sealing gaskets are in multiple groups and are circumferentially distributed outside the cross valve, and the connecting grooves are in multiple groups and are circumferentially distributed outside the cross valve.

[0013] There are multiple groups of condensation columns which are evenly distributed inside the condensation bin. After the water mist is collected by the collecting fan, it is condensed and liquefied through the condensation columns. Meanwhile, the water mist that cannot be liquefied is filtered and liquefied through the buffer sponge, which greatly improves the recovery efficiency of the device.

[0014] A mounting groove is provided on the outside of the scale plate, a mounting block is movably connected inside the mounting groove, a laser pen is movably connected inside the mounting block, and the adjusting bearing is fixedly connected to the scale plate.

[0015] The liquid storage bin is fixedly connected with an extension base inside, the extension base is fixedly connected with a telescopic bin outside, the telescopic bin is fixedly connected with a sealing spring inside, the sealing spring has a close column plate fixedly connected to the outside of one end away from the telescopic bin, and the close column plate is movably connected to the sealing gasket.

[0016] A transparent sealing plate is fixedly connected to the outside of the observation chamber, and the transparent sealing plate provides sealing for the observation chamber and facilitates the experimental display of the laser path.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, through the receiving channel, the liquid outlet channel, the cross valve and the booster pump, refraction experiments can be carried out on different liquid media to avoid the light being affected by the liquid container and changing the refraction result. At the same time, it is convenient to replace different types of liquid media later, which greatly improves the flexibility and accuracy of the device.

[0019] 2. In the present invention, through the water storage tank, circulation pump, condensate tank, atomizing nozzle and collecting fan, during the refraction experiment, if the observation effect is poor, the water can be atomized by the atomizing nozzle and filled into the inside of the observation tank, thereby increasing the effect of the Tyndall effect of the laser passing through the water mist inside the observation tank and increasing the observation effect. At the same time, the water mist is continuously discharged by the collecting fan to avoid the accumulation of water mist inside the observation tank, thereby greatly improving the observation effect of the device.
