[0052] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0053] It is important to understand that the formation process of hail is generally as follows: 1. Convection formation: Hail usually needs to form in strong convective air currents, which usually occur under unstable atmospheric conditions, such as storms or thunderstorms. 2. Ice nucleus formation: In convective air currents, when air rises to higher altitudes, it encounters tiny particles such as cloud droplets or ice crystals, which are called ice nuclei. 3. Ice nucleus growth: When the air rises and encounters the ice nucleus, water vapor condenses on the surface of the ice nucleus to form an ice layer. 4. Updraft effect: Driven by convective air currents, hail particles continue to rise. 5. The presence of a liquid water layer: During the rise of hail particles, a layer of liquid water may exist. 6. Repeated freezing and melting cycles: When hail particles continue to rise and come into contact with colder air, liquid water may refreeze, and hail is formed in this cycle.

[0054] The invention provides a demonstration device for simulating the formation of hail, which is used for dynamically demonstrating the formation process of hail. The demonstration purpose is relatively clear, the fun is strong, the participation and interactivity are strong, the knowledge points are presented relatively concisely and are easy to accept, so that the audience can learn knowledge while playing.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the demonstration device for simulating hail formation includes structures such as a fan 21, a pipe 2, a cloud simulation lamp, a spiral track 7, and an imaging component 5. One end of the pipe 2 has a sphere inlet and an airflow inlet, and the other end of the pipe 2 is connected to the spiral track 7. The spiral track 7 extends downward, and the fan 21 is connected to the airflow inlet. The fan 21 is used to provide wind to push the sphere to rise along the pipe 2. The sphere is used to simulate ice crystals and hail formed by ice crystals. The main body of the demonstration device for simulating hail formation can be fixedly set on a vertical curtain wall for display to the audience.

[0056] The fan 21 is arranged upstream of the pipeline 2, and the cloud simulation lamp is arranged midstream of the pipeline 2 and above the fan 21. The fan 21 is used to generate wind force simulating rising airflow to push the sphere to rise in the pipeline 2. The sphere is used to simulate ice crystals (or ice nuclei) and hail formed by ice crystals.

[0057] The pipe 2 is used to provide a limit and set track for the upward movement of the ball. Optionally, the pipe 2 is a transparent pipe 22 to show the entire operation process to the audience. The ball can be a colored ball or an ocean ball in the prior art to enhance the visual effect.

[0058] The cloud simulation lamp is installed on the pipe 2, and part of the structure of the pipe 2 is arranged inside the cloud simulation lamp. The cloud simulation lamp is used to light up when the sphere passes through the pipe 2 structure located inside the cloud simulation lamp. The cloud simulation lamp is provided with at least one level on the pipe 2, and simulates the sphere in the cloud layer through at least one visual signal; when the cloud simulation lamp is provided with multiple levels, it can have different appearances, such as simulating that the cloud layer is getting bigger and bigger, and is used to simulate different higher and higher cloud layers. The visual signal here can be a light signal or an image simulation, animation playback, etc.

[0059] Specifically, in this embodiment, the spiral track 7 is arranged inside the imaging assembly, and the imaging assembly is arranged on one side of the pipe 2. The imaging assembly includes: a box 53, and a reflector 51 and a semi-transparent mirror 52 arranged in the box 53. Among them, the semi-transparent mirror 52 and the reflector 51 are arranged parallel to each other, the semi-transparent mirror 52 is arranged on the side of the box 53 facing the audience, and the reflector 51 is arranged on the side of the box 53 away from the audience. The spiral track 7 is located between the reflector 51 and the semi-transparent mirror 52, which is used to repeatedly reflect the spherical image to simulate the process of ice crystals forming hail after repeated collisions. The imaging assembly is used to make the spiral falling motion of the sphere produce a messy image to simulate the process of ice crystals forming hail after repeated collisions. Due to the effects of the spiral track 7 and the imaging assembly, only one sphere can be used to achieve the effect of multiple sphere collision display, vividly showing the process of ice crystals forming hail after repeated collisions.

[0060] In the above embodiment, the demonstration device simulating the formation of hail not only vividly displays the changes of ice crystals in the rising process, but also can achieve the effect of multiple sphere collision display by using only one sphere with the help of spiral tracks and imaging components, and vividly displays the process of hail formation after repeated collisions of ice crystals. It is highly interesting, and the knowledge points are presented in a relatively concise and easy to accept, allowing the audience to learn knowledge while playing.

[0061] In some embodiments, Figure 1-Figure 3 As shown, the demonstration device simulating hail formation also includes a first control component 1 (or booth component), which includes a display frame 12 and a pressing ball 11, a guide rod 13 and a sensing structure 14 installed on the display frame 12. The pressing ball 11 is set on the top of the guide rod 13 and triggers the sensing structure 14 by pressing. The sensing structure 14 is used to monitor the position of the pressing ball 11 or the guide rod 13. When the pressing ball 11 is detected to be pressed, the sensing structure 14 transmits a signal to the processor of the demonstration device simulating hail formation to control the fan 21 to start. The first control component 1 can effectively improve the audience's participation and interactivity, allowing the audience to learn knowledge while playing.

[0062] As an achievable method, the display stand 12 can be located on one side of the pipe 2 as an operating table; the pressing ball 11 can be located on the top of the display shell as a structure for the audience to operate, and the pressing ball 11 is connected through the guide rod 13. The sensing structure 14 can be a pressure sensor or a switch, which transmits the trigger signal to the processor or directly to the fan 21 to control the fan 21 to start. Taking the pressure sensor as an example, Fig. 9 As shown, the pressure sensor can be connected to the circuit breaker of the fan 21 through an electric wire, the pressure sensor is simultaneously connected to a light emitting diode, and the pressure sensor circuit is also connected to the central control system.

[0063] Afterwards, the audience can pick up a marine ball from the ball storage basket 61 fixed on the exhibition wall and put it into the transparent pipe 22 with a trumpet-shaped front end (inlet pipe 64). Optionally, the ball inlet pipe 64 is fixedly connected to the fan 21 pipe, a section of a reducing hose is provided between the fan 21 and the pipe, and they are respectively fastened with a clamp, a throttling device and a dust filter valve are provided at the inlet of the fan 21, the throttling device is fastened with the fan 21 clamp, and the dust filter valve is fastened with the throttling device clamp.

[0064] In some embodiments, Figure 1 and Figure 2As shown, the cloud simulation lamp includes a first special-shaped light box 23, a second special-shaped light box 24 and a third special-shaped light box 25, each of which has a different shape to simulate the cloud layer at different stages of the ice crystal's rise; each special-shaped light box is provided with a light strip, each light strip is controlled by a sensor or a preset program to emit light at least when the sphere passes by. The cloud simulation lamps designed in three layers are located at different heights, which can simulate clouds at different stages and intuitively show the changes of ice crystals during their rise.

[0065] As an implementable method, the first special-shaped light box 23 has an appearance of a structure composed of three prisms, and a first sensor 26 is arranged inside the structure; the second special-shaped light box 24 has an appearance of a smaller cloud structure, and a second sensor 27 is arranged inside the structure; the third special-shaped light box 25 has an appearance of a larger cloud structure, and a third sensor 28 is arranged inside the structure; each sensor is used as a signal feedback device, and gives a feedback signal when the ball passes by, which is used to control the lighting of the lamp beads in the light box; in this embodiment, each sensor can be set at the starting end of each light box. The opening of the light strips or lamp beads in each light box can also be controlled by a preset program, such as opening the light strip of the first special-shaped light box 23 after the first preset time interval after the fan 21 is turned on, opening the light strip of the second special-shaped light box 24 after the second preset time interval after the fan 21 is turned on, and opening the light strip of the third special-shaped light box 25 after the third preset time interval after the fan 21 is turned on.

[0066] In some embodiments, at least one pipeline 2 is provided, the air outlet of the fan 21 is connected to the air inlet, the sphere enters the pipeline 2 through the sphere inlet, the sphere inlet is arranged upward, and the pipeline 2 is configured as a transparent pipeline 22 at least at the position of the cloud simulation lamp. When two or more pipelines 2 are provided, each pipeline 2 is arranged in parallel, each pipeline 2 passes through the cloud simulation lamp, and the end of each pipeline 2 is connected to the starting end of the spiral track 7. Figure 4 As shown, three pipelines 2 are provided, each of which is equipped with an inlet pipeline 64 . Each pipeline can work independently, but will eventually converge into the same spiral track 7 .

[0067] As a feasible method, the pipeline 2 may include a transparent straight pipe and a transparent curved pipe. There is a connecting joint between the transparent straight pipe and the transparent curved pipe, which is seamlessly sealed with UV glue. The transparent pipe and the special-shaped light box are seamlessly bonded and fixed with UV glue. The light bar in the special-shaped light box is fixed with the shape of the light box. The transparent pipe has a hole for installing a sensor, the sensor signal line is connected to the light bar circuit, and the transparent pipe is connected to the curtain wall with a transparent clip.

[0068] After each section of the pipeline is processed according to the design requirements, it is spliced ​​and formed; after the special-shaped pipeline is processed by the hot bending process, the glass tube becomes softer and can be formed into pipelines of different specifications and shapes, and then the pipelines are spliced ​​and formed.

[0069] According to the different shapes, it can be divided into local hot bending and overall hot bending; the hot bending should have a smooth transition and the sphere should pass through naturally and smoothly.

[0070] Splicing and forming requires special organic glass glue for bonding. The bonding should be firm and reliable, without glue overflow and flow defects; each joint should have a smooth transition without abnormal protrusions and abnormal depressions. After the overall forming, a sealing test is carried out, and installation and debugging can be carried out after passing the test.

[0071] In some embodiments, the imaging component 5 may also be provided with a light strip or light beads that can be turned on automatically. When the sphere passes through the imaging component 5, it turns on to enhance the light and shadow effects and attract the audience's attention.

[0072] As an achievable method, the box 53 can be made of tempered glass, the imaging component 5 is embedded in the curtain wall, the imaging component 5 wraps the spiral track 7, and the spiral track 7 is seamlessly bonded to the outer shell of the second control component 3 with UV glue. The semi-transparent and semi-reflective mirror 52 (also called a semi-transparent and semi-reflective mirror or a spectroscope) is an optical device that has the function of dividing light into two parts: transmission and reflection. It is transparent on one side and reflective on the other side. The semi-transparent and semi-reflective mirror 52 is usually made of a special thin film coating that has specific optical properties to achieve the separation of transmission and reflection. This coating can cause light of a specific wavelength to interfere and reflect on the surface. When light is incident from the transparent side of the semi-transparent and semi-reflective mirror 52, part of the light will pass through the coating, while the other part of the light will be reflected by the coating. The relative intensity of the transmitted light and the reflected light depends on the coating used and the design parameters. The combined use of the reflector 51 and the semi-transparent and semi-reflective mirror 52, combined with the spherical running track of the spiral track 7, can simulate the process of many ice crystals forming hail after repeated collisions.

[0073] After the sphere lands on the spiral track 7 and completes the simulation of the hail formation process, the sphere can automatically return to the initial position. However, in order to enhance the interactivity with the audience, the audience can also participate in the process of the sphere returning to its original position.

[0074] In some embodiments, Figure 1 and Figure 5 As shown, the demonstration device simulating hail formation also includes a second manipulation component 3 fixedly arranged at the bottom of the box 53 of the imaging component 5, and the second manipulation component 3 is used to eject the ball into the ball lifting mechanism 4.

[0086] Figure 8 FIG. 1 is an operation flow chart of a demonstration device for simulating hail formation in one embodiment of the present invention. Figure 8 As shown, the operation steps include:

[0087] 1. The audience presses the push ball on the upper end of the booth of the first control component to trigger the pressure switch, which starts the three axial flow fans at the end of the transparent pipe;

[0088] 2. The audience takes a ball from the ball storage basket fixed on the exhibition wall and puts it into the transparent pipe with a trumpet shape at the front end. Driven by the wind, the ball moves along the transparent pipe;

[0089] 3. When passing through three groups of light boxes, the sensor is triggered to light up the light boxes; the ball falls into the spiral track;

[0090] 4. With the background of the imaging components at the back, the effect of numerous spheres colliding with each other is revealed;

[0091] 5. The ball falls on the bottom plate of the ejection mechanism of the second control assembly, and under the action of the upper connecting rod installed on the base, the ball is ejected into the hole in front of the bottom plate;

[0092] 6. The ball in the hole falls onto the support plate of the ball lifting mechanism, and the support plate drags the ball upward, and finally passes through the recovery pipe and returns to the ball storage basket.

[0093] In the above process, the audience can have three manual participation steps, namely manually pressing the ball to start the fan, manually dropping the sphere and manually ejecting the sphere. The audience participation is high, and graphic explanations can be configured to introduce the process of hail formation through dynamic display of real objects, which has a good popular science effect.
