Description
Technical Field

Because the rain is usually gushed in summer, the sky in the second half of the rain is exposed out of the sun, and the thick cloud layer is arranged in the other half of the rain, at the moment, when sunlight passes through the cloud layer and water vapor and water drops in the air, the sunlight is refracted into the seven-color neon.

Further, in order to realize the appearance of the neon and the neon, the embodiment sets the shell 2 as a black light-transmitting acrylic piece for the shell 2.
In application, the use of acrylic for the housing 2 requires both color and light transmittance, since a relatively strong light source is required to reproduce the rainbow, and the black acrylic can improve contrast and make it easier to see the rainbow.
Secondly, in order to achieve the optimal observation effect, the shell 2 needs to use a semi-transparent black acrylic plate; if the light-tight acrylic plate is used, the light emitted by the laser light source 8 is totally reflected, so that the rainbow observation effect is reduced; the semi-transparent acrylic plate can reflect part of light, and the rainbow observation effect is improved.
With respect to the track mechanism 3 described above, the track mechanism 3 further includes a first slider 33 and a second slider 34 slidably mounted on the track; the CCD camera 7 is mounted on the first slider 33, and the laser light source 8 is mounted on the second slider 34.

1. the track mechanism 3 further comprises a motion controller 31, wherein the motion controller 31 is used for controlling the laser light source 8 and the CCD camera 7 to independently move at different angles;
2. The motion controller 31 is used to control the laser light source 8 and the CCD camera 7 to move synchronously at a fixed angle.
The observation principle of the laser light source 8 and the CCD camera 7 is that the light emitted by the laser light source 8 is used for irradiating the water mist sprayed by the atomizing nozzle 6 at different angles to form rainbow and neon; the CCD camera 7 is used to observe the rainbow and neon at different angles.
The beneficial effects are that: the scheme is different from the fixed shooting in the prior art in that a magnetic levitation track is used for controlling the movement of the laser light source 8 and the CCD camera 7, a rainbow which is presented by continuously changing the incident angle of the laser light source 8 can be shot, and the change of the angle rainbow and the deflection angle of the laser light source 8 which are continuously changed is measured through the angle scale on the annular track 32.
In application, the annular track 32 is adopted, and the annular track 32 is made of conductive weak magnetic materials such as copper and aluminum; an electromagnet is arranged in the sliding block, and the first sliding block 33 and the second sliding block 34 move on the annular track 32 by independently supplying an alternating current power supply to the first sliding block 33 and the second sliding block 34 and controlling the frequency, the voltage and the current of the alternating current power supply by using a power amplifier; the magnetic suspension scheme utilizes the vortex suspension principle.
Control method for the motion controller 31: (1) The second slider 34 and the laser light source 8 can be levitated by the motion controller 31, and the second slider 34 and the laser light source 8 can be moved along the track by changing the exciting current in the exciting coil in the track. By changing the position of the laser light source 8 by the motion controller 31, a change in the incident direction of the laser light source 8, which is a rainbow or neon image, is observed in the CCD camera 7.
(2) The first sliding block 33 and the CCD camera 7, the second sliding block 34 and the laser light source 8 can be suspended at the same time through the motion controller 31, the first sliding block 33 and the CCD camera 7, the second sliding block 34 and the laser light source 8 can move along the track at the same time through changing exciting current in the track exciting coil, at the same time, the included angle between the CCD camera 7 and the laser light source 8 is fixed, the CCD camera 7 and the laser light source 8 move in the track at the same time, and the change condition of shooting iridescent images and neon images in different directions can be observed in the CCD camera 7.
The rainbow and neon images with different angles are shot, and the rainbow and neon images with different angles are compared, so that the different incidence angles of the light sources and the differences of the rainbow and neon deflection angles measured by different shooting angles can be compared.
Regarding the arrangement of the above-described atomizing nozzles 6, referring to fig. 1, there are a plurality of atomizing nozzles 6, and a plurality of atomizing nozzles 6 are uniformly arranged along the length direction of the water supply pipe 42.
Further, in order to make the rainbow and neon appear in the manufactured water mist, as shown in fig. 3, the atomizing nozzle 6 is provided with a water inlet 61, a pressurizing micro-pipe 62, an atomizing port 63 and a fan-shaped notch 64 which are sequentially communicated; the sector-shaped notch 64 is provided with symmetrical inclined surfaces 641; the atomizer 6 is used for spraying fan-shaped spray.
When in use, the solution is further pressurized by the pressurizing micro-pipeline 62, sprayed out from the atomizing port 63, and then limited by the fan-shaped notch 64 to manufacture fan-shaped water mist; a plurality of atomizing heads simultaneously spray fan-shaped water mist to manufacture a fan-shaped water curtain; the laser light source 8 projects strong light on the fan-shaped water curtain to manufacture rainbow and neon; the fan-shaped water mist is mainly in a circular arc shape, which is observed in daily life, and the fan-shaped water mist is just matched with the shape of the rainbow to simulate the effect similar to the rainbow which is naturally generated.
Regarding the structure of the above-described water supply unit 5, this embodiment is shown in fig. 1 and 2, the water supply unit 5 is provided with a pool 51, a water collecting plate 52, and an overflow preventing plate 53; the two intersecting sides of the pool 51 are in sealing connection with the inner side of the mounting plate 22 and the projection surface 21; the water collecting plate 52 is provided with water collecting edges 521 and inclined collecting edges 522 on both sides in the length direction; the water collecting edge 521 is in sealing connection with the projection surface 21, two ends of the water collecting plate 52 are respectively in sealing connection with the water inlet 511 of the water tank 51 and the mounting plate 22, and the water collecting plate 52 is obliquely mounted from the water collecting oblique edge 522 to the water collecting edge 521; the two sides of the anti-overflow plate 53 in the length direction are provided with an anti-inclined edge 532 and an anti-overflow edge 533; one end of the anti-overflow plate 53 is in sealing connection with the mounting plate 22, and one side of the other end of the anti-overflow plate 53 is sequentially provided with a right-angle edge 531 and an anti-sloping edge 532, wherein the right-angle edge 531 is in sealing connection with the water inlet 511; the anti-overflow plate 53 is mounted obliquely from the anti-overflow edge 533 to the anti-overflow edge 532 in sealing engagement with the collection edge.
When the water pump is used, only water or prepared solution is needed to be added into the water tank 51, the water pump 41 pumps the water of the water tank 51, the solution enters the internal pressurizing pump from the liquid inlet 411 of the water pump 41, after being pressurized, the solution is sprayed out from the liquid outlet 412, the solution enters the water supply pipe 42, and then the pressurized solution is sprayed out on the atomizing nozzle 6 on the water supply pipe 42; when the rainbow and the neon are observed, the atomization nozzle 6 continuously sprays; in order to realize the environmental protection and sustainability of the device in use, after the water mist sprayed by the atomizing nozzle 6 falls, the far water mist sprayed out falls onto the anti-overflow plate 53, the near water mist sprayed out falls onto the water collecting plate 52, and the water collecting plate 52 and the anti-overflow plate 53 form proper inclination when being installed, so that the collected water mist flows to the water inlet 511 of the water tank 51 after being converged; the collected solution flows into the water tank 51, is pumped by the water pump 41 again and then is pressurized and sprayed out, so that the sustainable use of the water mist-solution is formed, and the design rule of environmental protection and low carbon is met.
In addition, the use of different solutions can also produce different effects on the iridescence, where the refractive index of the solution is related, for example:

2. The refractive index of light of different solutions is different, so that the refractive angles of light of different solutions are different, and in the formation process of the rainbow and the neon, light needs to be refracted for a plurality of times, if the solution with high refractive index is used, the refractive angle of light in the refraction process is larger, so that the deflection angle of the final observation rainbow and the neon is different.
