Description

Technical Field

[0001] This invention relates to the field of rainbow simulation experimental technology, specifically to a three-view integrated imaging optical device. Background Technology

[0002] Rainbows, a common atmospheric optical phenomenon, are formed by the dispersion of light caused by refraction, internal reflection, and secondary refraction within water droplets. In physics teaching and science demonstrations, several simple methods are traditionally used to simulate rainbows indoors, such as: using a prism to disperse natural or artificial light; using a plane mirror inserted obliquely into a basin of water to reflect and disperse light; or directly using a spray device to create a water mist rainbow under sunlight at a specific angle.

[0003] However, these traditional methods have significant limitations. First, they are heavily influenced by environmental conditions. For example, the prism and water basin methods require precise manual adjustment of the light source and component angles, and struggle to consistently and clearly reproduce rainbows; the mist method typically requires outdoor sunlight and cannot be easily demonstrated indoors. Second, these methods mostly simulate only a single primary rainbow phenomenon and cannot vividly demonstrate more complex optical phenomena, such as double rainbows (neon rainbows) and the Alexandria band between them. Finally, traditional apparatuses are often single-function and cannot systematically study and demonstrate the impact of key parameters such as background light intensity, light source incident angle, and water mist morphology on rainbow observation, thus limiting their application in in-depth teaching and scientific research. Summary of the Invention

[0004] The purpose of this invention is to provide a three-view integrated imaging optical device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A three-view integrated imaging optical instrument device includes an optical imaging tube, an adjustable light source assembly installed at the front end of the optical imaging tube, a backlight plate installed at the rear end of the optical imaging tube, transparent plates embedded on both the front and rear sides of the optical imaging tube, a spray rainbow mechanism embedded at one end of the optical imaging tube, and a drain outlet provided at the lower end of the optical imaging tube. The spray rainbow-making mechanism includes a swing frame and a water pipe located at the upper end of the swing frame. An atomizing nozzle is installed at one end of the water pipe, and a water inlet is provided at the other end of the water pipe. A fixing sleeve is fixedly installed in the middle of the outer side of the water pipe, and a rotating shaft is fixedly connected to the front and rear ends of the outer side of the fixing sleeve.

[0006] As a further embodiment of the present invention: a U-shaped groove is provided on the inner side of one end of the swing frame facing the atomizing nozzle, an atomizing plate is embedded in the inner side of the U-shaped groove, and the atomizing plate is fixedly connected to the swing frame by a set of fastening bolts.

[0007] As a further embodiment of the present invention: a screw is fixedly connected to one end of each of the rotating shafts, and lugs are fixedly connected to the front and rear sides of one end of the optical imaging tube. The screw passes through the inner side of the corresponding lug, and the screw and the corresponding lug are fixedly connected by a set of nuts.

[0008] As a further embodiment of the present invention: a set of bearing seats containing bearings are installed on the upper end of the swing frame away from the atomizing plate, and the rotating shaft passes through the inner side of the corresponding bearing seat.

[0009] As a further embodiment of the present invention: a sliding plate is slidably connected to the inner side of the swing frame away from the atomizing plate, a set of return springs is installed at the lower end of the sliding plate, and guide bars are slidably connected to the front and rear sides of the sliding plate, each of the guide bars being fixedly connected to the inner sidewall of the swing frame.

[0010] As a further embodiment of the present invention: the adjustable light source assembly includes a strip frame, on the inner side of which are arranged mutually parallel ball screws and guide rods. One end of the ball screw is located on the outer side of the strip frame and is fixedly connected to a screw motor, and a nut pair is engaged with the ball screw. A guide sleeve is slidably connected to the guide rod. A connecting plate is connected between the nut pair and the guide sleeve. A U-shaped frame is fixedly connected to the upper end of the connecting plate, and a high-intensity lamp is installed inside the U-shaped frame.

[0011] As a further embodiment of the present invention: a set of connecting frames is fixedly connected to the rear end of the strip frame, and the connecting frames are fixedly installed at the lower end of the front side of the optical imaging tube.

[0012] As a further embodiment of the present invention: the upper outer side of each high-intensity lamp is fixedly connected with a rotating column that penetrates the inner side of the U-shaped frame. The rotating column is rotatably connected to the U-shaped frame, and a gearbox is installed at one end of one of the rotating columns on the outer side of the U-shaped frame. A drive motor is installed at one end of the gearbox, and an encoder is installed at one end of the drive motor.

[0013] As a further embodiment of the present invention: the backlight panel is composed of a light source, a light guide plate, and an optical film.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention integrates an adjustable light source assembly, a spray rainbow-generating mechanism, and a backlight panel into a single optical imaging tube, creating a closed experimental environment unaffected by external weather and lighting conditions. This allows rainbow generation and observation to be performed stably and repeatedly in any indoor environment, greatly improving the reliability and convenience of teaching demonstrations. The adjustable light source assembly uses a lead screw motor and a drive motor to precisely control the position of the high-intensity lamp in the horizontal direction and the illumination angle in the vertical plane. This not only makes it easier to quickly find the best light path to generate a rainbow, but also allows students to intuitively study the decisive influence of the incident angle of the light source on the position, shape, and clarity of the rainbow, elevating qualitative observation to the level of quantitative research. By introducing a swingable and replaceable atomizing plate design, and through the periodic impact and detachment of water mist from the atomizing plate, the device can dynamically change the shape and distribution of the water mist, thus successfully simulating the main rainbow, the secondary rainbow, and the Alexander Belt phenomenon between them; this is difficult to achieve with traditional experimental methods, greatly enriching the teaching content. The backlight panel can provide two different background lights, bright and dark. By switching the background, the experimenter can clearly observe the significant effect of background contrast on the visibility of the rainbow, thereby understanding the importance of background selection when observing rainbows in natural environments and cultivating comprehensive optical analysis skills.

[0017] Please see Figures 1-6 In this embodiment of the invention, the three-view integrated imaging optical instrument device includes an optical imaging tube 1, an adjustable light source assembly 6 installed at the front end of the optical imaging tube 1, a backlight plate 3 installed at the rear end of the optical imaging tube 1, transparent plates 2 embedded on both the front and rear sides of the optical imaging tube 1, a spray rainbow mechanism 4 embedded at one end of the optical imaging tube 1, and a drain outlet 5 provided at the lower end of the optical imaging tube 1. The water sprayed during the experiment can be concentrated and discharged through the drain outlet 5, keeping the experimental environment clean.

[0018] exist Figure 2 , Figure 3 and Figure 4 In the spray rainbow-making mechanism 4, there is a swing frame 41 and a water pipe 48 located at the upper end of the swing frame 41. One end of the water pipe 48 is equipped with an atomizing nozzle 412, and the other end of the water pipe 48 is provided with a water inlet 47. The water inlet 47 is connected to external pressurized water, such as tap water, via a flexible hose. Tap water enters the water pipe 48 through the water inlet 47 and is then sprayed out from the atomizing nozzle 412 in a mist form, forming a rainbow under light. The outer side of the water pipe 48... A fixing sleeve 411 is fixedly installed in the middle. Rotating shafts 410 are fixedly connected to the front and rear ends of the outer side of the fixing sleeve 411. A U-shaped groove 415 is provided on the inner side of one end of the swing frame 41, directly opposite the atomizing nozzle 412. An atomizing plate 413 is embedded in the inner side of the U-shaped groove 415. The atomizing plate 413 is fixedly connected to the swing frame 41 by a set of fastening bolts 414. After loosening the fastening bolts 414 counterclockwise, the atomizing plate 41 can be pulled out from the U-shaped groove 415. 3. By replacing the atomizing plate 413 with one of different specifications, when the water mist sprayed from the atomizing nozzle 412 hits the atomizing plate 413, some of the water mist passes through the atomizing plate 413, while the other part of the water mist is refracted on the atomizing plate 413, thus producing different types of rainbows. When the atomizing plate 413 is not installed, the water mist can be sprayed out in the same form. Each rotating shaft 410 is fixedly connected to one end with a screw 42, and the front and rear sides of one end of the optical imaging tube 1 are fixedly connected with lugs 7. The screw 42 passes through the inner side of the corresponding lug 7, and the screw 42 and the corresponding lug 7 are fixedly connected by a set of nuts 49. This allows the rotating shaft 410, the fixing sleeve 411, and the water pipe 48 to be fixed on the optical imaging tube 1 and kept stationary. The atomizing nozzle 412 is embedded in the optical imaging tube 1 from one end, ensuring that the atomizing nozzle 412 remains stable. This ensures that the device can maintain a long service life and stable performance even in frequent teaching use.

[0019] exist Figure 2 and Figure 3In the swing frame 41, a set of bearing seats 43 containing bearings are installed on the upper end of the swing frame 41 away from the atomizing plate 413. The rotating shaft 410 passes through the inner side of the corresponding bearing seat 43. Since the rotating shaft 410 and the screw 42 are fixed on the optical imaging tube 1 and remain stationary, the bearing seat 43 and the swing frame 41 can rotate around the rotating shaft 410. A sliding plate 45 is slidably connected to the inner side of the swing frame 41 away from the atomizing plate 413. A set of return springs 44 are installed at the lower end of the sliding plate 45, and guide bars 46 are slidably connected to the front and rear sides of the sliding plate 45. Each guide bar 46 is fixedly connected to the inner wall of the swing frame 41. Since the water pipe 48 is fixed to the optical imaging tube 1, when the water mist sprayed from the atomizing nozzle 412 impacts the atomizing plate 413, the swing frame... At the junction of the rotating shaft 410 and the bearing seat 43, the swing frame 41 rotates clockwise. When the swing frame 41 rotates to a certain angle, the water mist sprayed from the atomizing nozzle 412 can no longer impact the atomizing plate 413. At the same time, the sliding plate 45 hits the water pipe 48, the return spring 44 is deformed by pressure, and the sliding plate 45 slides along the guide bar 46. When the pressure on the return spring 44 disappears, the return spring 44 extends and pushes the sliding plate 45 to move in the opposite direction, thereby causing the swing frame 41 to rotate counterclockwise at the junction of the rotating shaft 410 and the bearing seat 43. The atomizing plate 413 returns to the impact range of the water mist sprayed from the atomizing nozzle 412, blocking the water mist again. The shape and angle of the water mist are changed repeatedly, thus simulating the Alexander Belt, i.e., the double rainbow phenomenon.

[0020] exist Figure 5 and Figure 6In the adjustable light source assembly 6, there is a strip frame 61. A ball screw 62 and a guide rod 64 are arranged parallel to each other on the inner side of the strip frame 61. One end of the ball screw 62 is located on the outer side of the strip frame 61 and is fixedly connected to a screw motor 63. A nut pair 612 is engaged with the ball screw 62. A guide sleeve 613 is slidably connected to the guide rod 64. A connecting plate 614 is connected between the nut pair 612 and the guide sleeve 613. A U-shaped frame 66 is fixedly connected to the upper end of the connecting plate 614. A high-intensity lamp 65 is installed inside the U-shaped frame 66. The rear of the strip frame 61... A set of connecting brackets 67 is fixedly connected to the end, and the connecting brackets 67 are fixedly installed at the lower end of the front side of the optical imaging tube 1, so that the adjustable light source assembly 6 can be installed together with the optical imaging tube 1; the ball screw 62 is driven to rotate by the lead screw motor 63, so that the nut pair 612 moves horizontally along the ball screw 62; thereby driving the connecting plate 614 and the guide sleeve 613 to move horizontally along the guide rod 64, and thus causing the U-shaped frame 66 and the high-intensity lamp 65 to move horizontally, adjusting the horizontal position of the high-intensity lamp 65; the light emitted by the high-intensity lamp 65 passes through the transparent plate. After 2, it enters the optical imaging tube 1, where it is reflected and refracted on the water mist, thus forming a rainbow. Adjusting the horizontal position of the high-intensity lamp 65 can better form the rainbow. Each high-intensity lamp 65 has a fixed upper outer end connected to a rotating column 68 that penetrates the inner side of the U-shaped frame 66. The rotating column 68 is rotatably connected to the U-shaped frame 66, and one end of one of the rotating columns 68 is located on the outer side of the U-shaped frame 66, with a gearbox 69 installed thereon. A drive motor 610 is installed at one end of the gearbox 69, and an encoder 611 is installed at one end of the drive motor 610. The encoder 611 is connected to the drive motor... Motor 610 drives gearbox 69 to rotate, which in turn drives rotating column 68 and high-intensity lamp 65 to rotate together, thereby adjusting the angle of high-intensity lamp 65 to change the incident angle of light and thus better form a rainbow. Encoder 611 can calculate the rotation angle of drive motor 610, thereby precisely controlling the illumination angle of high-intensity lamp 65. This not only makes it easier to quickly find the best light path to generate a rainbow, but also allows students to intuitively study the decisive influence of the incident angle of the light source on the position, shape and clarity of the rainbow, elevating qualitative observation to the level of quantitative research.

[0021] exist Figure 1 In the middle, the backlight panel 3 is composed of a light source, a light guide plate, and an optical film. The light source can be an LED or a CCFL. The light source emits light, and the light guide plate guides the scattering direction of the light to achieve uniform light distribution. The light is then directed onto the optical film through the light guide plate, and the optical film homogenizes and brightens the light. The light passes through the transparent plate 2 on the back side of the optical imaging tube 1 and enters the optical imaging tube 1, forming a rainbow background. The backlight panel 3 can be adjusted to create either a dark or bright background. For example, in a dark background, a shadowy forest or building can be formed behind the water mist, resulting in a very clear rainbow due to the high contrast with the background. In a bright background, a bright sky or white wall can be placed behind the water mist, making the rainbow blurry and difficult to discern. By switching the background, the experimenter (such as a student) can clearly observe the significant impact of background contrast on the visibility of the rainbow, thereby understanding the importance of background selection when observing rainbows in a natural environment and cultivating comprehensive optical analysis skills.

[0022] Working principle: When it is necessary to simulate the formation of a rainbow, firstly, connect the water inlet 47 to the external pressurized water through a hose, such as connecting it to tap water; Then, tap water enters the water pipe 48 from the inlet 47 and is sprayed out from the atomizing nozzle 412 in the form of atomization, and the water mist is sprayed into the optical imaging tube 1. Next, the high-intensity light 65 is turned on. The light emitted by the high-intensity light 65 passes through the transparent plate 2 and then into the optical imaging tube 1. It is reflected and refracted on the water mist, thus forming a rainbow. After the backlight panel 3 is turned on, the backlight panel 3 illuminates the inside of the optical imaging tube 1. The experimenter can then observe the rainbow inside the optical imaging tube 1 by looking through the transparent plate 2 on the front side of the optical imaging tube 1. The ball screw 62 is rotated by the lead screw motor 63, causing the nut assembly 612 to move horizontally along the ball screw 62. This causes the connecting plate 614 and the guide sleeve 613 to move horizontally along the guide rod 64, which in turn causes the U-shaped frame 66 and the high-intensity lamp 65 to move horizontally, adjusting the position of the high-intensity lamp 65. The gearbox 69 is driven by the drive motor 610, which in turn drives the rotating column 68 and the high-intensity lamp 65 to rotate together, thereby adjusting the angle of the high-intensity lamp 65 to change the incident angle of the light, thus better forming a rainbow. When it is necessary to observe the double rainbow, the atomizing plate 413 is installed in the U-shaped slot 415 and the atomizing plate 413 is locked to the swing frame 41 by the fastening bolt 414; at this time, the water mist sprayed from the atomizing nozzle 412 hits the atomizing plate 413, part of the water mist passes through the atomizing plate 413, and the other part of the water mist impacts the atomizing plate 413 and is refracted on it; When the water mist sprayed from the atomizing nozzle 412 impacts the atomizing plate 413, the swing frame 41 rotates clockwise at the junction of the rotating shaft 410 and the bearing seat 43. After the swing frame 41 rotates to a certain angle, the water mist sprayed from the atomizing nozzle 412 can no longer impact the atomizing plate 413. At the same time, the sliding plate 45 hits the water pipe 48, the return spring 44 is deformed by pressure, and the sliding plate 45 slides along the guide bar 46. When the pressure on the return spring 44 disappears, the return spring 44 extends and pushes the sliding plate 45 to move in the opposite direction, thereby causing the swing frame 41 to rotate counterclockwise at the junction of the rotating shaft 410 and the bearing seat 43. The atomizing plate 413 returns to the impact range of the water mist sprayed from the atomizing nozzle 412, blocking the water mist again. This cycle repeats, changing the shape and angle of the water mist, thus simulating the Alexander Alexandrite band, i.e., the double rainbow phenomenon.
