Abstract

The tornado visualization device comprises a base, a smoke generating assembly, a power assembly and a radial adjustment assembly. The smoke generating assembly is arranged in the smoke generating chamber of the base and emits smoke outward through the smoke outlet hole, so that the airflow is visualized, and the airflow flow path and direction are easy to observe and more intuitive. The power assembly comprises a plurality of rotating platforms and a plurality of air outlet mechanisms. The air outlet mechanisms are arranged on the rotating platforms.

[0041] Please refer to the following: Figures 1 to 5 The tornado visualization device 1 provided in the embodiments of the present invention will be described below.

[0042] Please see Figure 1This invention provides a tornado visualization device 1, including a base 10, a smoke generating assembly 20, a power assembly 30, and a radial adjustment assembly 40. A smoke chamber 11 is formed at the center of the base 10, and multiple smoke outlets 121 are provided on the upper surface of the smoke chamber 11, communicating with the smoke chamber 11. The smoke generating assembly 20 is disposed within the smoke chamber 11. The power assembly 30 includes a fixed support 31, multiple rotating platforms 32, and multiple air outlet mechanisms 33. The fixed support 31 is annular (circular, square, etc.) and positioned above the base 10. The central part corresponds vertically to the smoke chamber 11. Multiple rotating platforms 32 are arranged on the fixed support 31 along the circumference of the smoke chamber 11. Air outlet mechanisms 33 are arranged one-to-one on the rotating platforms 32. The rotating platforms 32 can drive the air outlet mechanisms 33 to rotate around their own vertical axis. When multiple power components 30 are provided, the multiple power components 30 are arranged at intervals from top to bottom. The radial adjustment components 40 correspond one-to-one with the power components 30. The radial adjustment components 40 are used to drive the rotating platforms 32 to move radially along the fixed support 31, thereby increasing or decreasing the radius of the circle enclosed by the multiple rotating platforms 32.

[0043] Compared with the prior art, the tornado visualization device 1 provided in this embodiment of the invention has the following advantages:

[0044] The tornado visualization device 1 provided in this embodiment of the invention includes a base 10, a smoke generating component 20, a power component 30, and a radial adjustment component 40. The smoke generating component 20 is disposed in the smoke chamber 11 of the base 10, and smoke escapes outward through the smoke outlet 121, making the airflow visible and facilitating observation of the airflow path and direction, providing a more intuitive understanding. The power component 30 includes multiple rotating platforms 32 and multiple air outlet mechanisms 33. The air outlet mechanisms 33 are disposed on the rotating platforms 32. When the rotating platforms 32 rotate, they can change the blowing direction of the air outlet mechanisms 33, thereby changing the air outlet angle. When the power component 30 has multiple layers, by changing the wind speed and angle of entry of the multiple power components 30, a tornado state that is thicker at the top and thinner at the bottom or vice versa can be simulated. In use, the wind speed and angle of entry can be changed by the power component 30, and the radial position of the air outlet mechanism 33 can be changed by the radial adjustment component 40, which can simulate tornadoes of various shapes. Combined with the smoke generating component 20 that visualizes the airflow, it is convenient for demonstration or experimentation.

[0045] In this embodiment of the invention, the base 10 is used to provide stable support for the various components installed on it. The base 10 can be a seat component made of stainless steel, cast iron or other materials, or welded from other metal profiles.

[0046] The smoke chamber 11 has a hollow structure. The hollow interior of the smoke chamber 11 is used to accommodate the smoke outlet 121. The smoke chamber 11 can be circular, square, hexagonal, or other shapes. The smoke outlet 121 is located on the top of the smoke chamber 11 to allow smoke to escape. The escaped smoke flows with the airflow and can form a visible tornado.

[0047] The smoke generating component 20 is used to generate smoke and can be a commercially available, mature product; there are no restrictions on its specific model or specifications. The color of the smoke can be white, blue, green, etc.

[0048] The power assembly 30 is positioned above the base 10 and can be configured in one, two, or more layers as needed. The power assembly 30 includes a fixed bracket 31, a rotating platform 32, and an air outlet mechanism 33. Multiple rotating platforms 32 and multiple air outlet mechanisms 33 correspond one-to-one. The fixed bracket 31 surrounds the smoke chamber 11 of the base 10. The multiple rotating platforms 32 are evenly spaced along the circumference of the smoke chamber 11. The air outlet mechanisms 33 are mounted on the rotating platforms 32. The rotating platforms 32 can drive the air outlet mechanisms 33 to rotate around a vertical axis, thereby changing the air outlet direction. Multiple rotating platforms 32 can operate independently without affecting each other. Each rotating platform 32 contains a rotation drive component, such as a geared motor or a hydraulic rotary motor, which can drive the air outlet mechanism 33 to rotate via gear transmission, belt transmission, sprocket transmission, etc., thereby changing the air outlet angle. The fixed bracket 31 can be driven by a geared motor or other drive component to achieve the rotation of the entire power assembly 30. Multiple rotating platforms 32 can be controlled to rotate synchronously via a PLC controller or rotate individually.

[0049] In this embodiment of the invention, the fixed bracket 31 can be a ring-shaped metal plate, or a frame structure welded from steel profiles, plates or pipes, as long as it can support the installation of the rotating platform 32.

[0050] The radial adjustment assembly 40 is used to change the radial position of the power assembly 30, thereby changing the radial range of the tornado. The radial adjustment assembly 40 can be an electric telescopic rod, pneumatic push rod, hydraulic telescopic rod, etc., connected to the rotating platform 32, and the telescopic direction of the electric telescopic rod, pneumatic push rod, hydraulic telescopic rod, etc. is along the radial direction of the fixed bracket 31.

[0051] Please see Figure 1 , Figure 2 and Figure 3 In some possible embodiments, the smoke generating assembly 20 includes a plurality of smoke generating pipes 21 and a smoke generator. The plurality of smoke generating pipes 21 are respectively disposed in the smoke generating chamber 11. The smoke generating pipes 21 are annular and coaxially arranged with the fixed bracket 31. A plurality of smoke holes are opened on the smoke generating pipes 21 along their own circumference. The plurality of smoke generating pipes 21 are arranged sequentially from the center outward at intervals. The smoke generator is connected to the smoke generating pipes 21.

[0052] In this embodiment of the invention, the smoke-generating pipe 21 is annular, and the diameter of the multiple smoke-generating pipes 21 gradually increases from the center to the edge. The multiple smoke-generating pipes 21 can be connected to each other or individually connected to the smoke generator. The smoke generator can deliver smoke to the smoke-generating pipe 21 through a gas hose, and then escape from the smoke hole into the smoke-generating chamber 11.

[0053] Please see Figures 1 to 3 In some possible embodiments, the smoke generator includes multiple smoke generating units, each connected to a corresponding smoke-generating pipe 21. These units can produce smoke of different colors, with each color corresponding to a different smoke-generating pipe 21, facilitating the demonstration of airflow patterns at different radial positions of a tornado. The smoke generator can be located inside or outside the base 10, as long as it is connected to the smoke-generating pipe 21.

[0054] Please see Figure 1 and Figure 4 In some possible embodiments, the air outlet mechanism 33 includes an air guide duct 311 and a fan 332. The air guide duct 311 is located on the rotating platform 32 and has an air outlet channel that runs through the horizontal direction. The fan 332 is located in the air outlet channel and the air outlet side of the fan 332 faces the hollow part of the fixed bracket 31.

[0055] In this embodiment, the air guide duct 311 is a hollow cylindrical component. The cross-section of the air guide duct 311 can be circular, square, or other shapes. The fan 332 is installed inside the air outlet channel. The fan 332 can be any commercially available product such as an axial flow fan 332, as long as it can generate an airflow of appropriate magnitude. To ensure the stability of the tornado shape, multiple fans 332 can be selected from the same model and batch to ensure that the airflow of multiple fans 332 is consistent.

[0056] Please see Figure 5 In some possible embodiments, the air outlet mechanism 33 further includes a rectifier unit disposed in the air outlet channel and located on the air outlet side of the fan 332.

[0057] In this embodiment, a rectifier unit is provided in the air outlet channel. The rectifier unit can rectify the air blown out by the fan 332, making it blown out more evenly. The rectifier unit can be a honeycomb panel 333, a corrugated plate, or other components.

[0058] Please see Figure 5 In some possible embodiments, the rectifier unit includes a honeycomb panel 333 and a damping mesh 334. The honeycomb panel 333 is disposed on the air outlet side of the fan 332, and the damping mesh 334 is disposed on the side of the honeycomb panel 333 away from the fan 332.

[0059] The honeycomb panel 333 is a honeycomb-shaped mesh panel, and the damping mesh 334 is a component with multiple mesh holes, which can rectify the airflow and make it blow out more evenly.

[0060] like Figure 1 As shown, in a specific embodiment, the tornado visualization device 1 includes two layers of power components 30. Each layer of power components 30 consists of 12 individual rotating platforms 32 and air outlet mechanisms 33 (such as power fans 332). Each air outlet mechanism 33 has a rotating platform 32 below it, and each air outlet mechanism 33 has a honeycomb filter and two layers of damping nets 334 at its outlet to rectify the airflow. The rotation speed of the rotating platforms 32 is adjustable, as are the airflow speed and volume of the air outlet mechanisms 33. The 12 air outlet mechanisms 33 in the first layer can rotate as a whole with the fixed support 31, or they can rotate independently through their respective rotating platforms 32, thereby adjusting the tornado's angle of attack and rotation radius.

[0061] When the rotation angles of the first and second layer rotating platforms 32 are not consistent, a tornado state with a thicker top and thinner bottom, or vice versa, can be simulated. Combined with different rotation angles and wind speeds of the air outlet mechanism 33, even more different tornado shapes can be simulated. The smoke-generating pipe 21 can have three layers, inner and outer, and can generate smoke according to different rotation angles to visualize the tornado. The top cover 12 of the smoke-generating chamber 11 has a mesh-like perforated structure, allowing the smoke from the lower layer to flow through the smoke outlet 121 to the wind rotation area.

[0062] Please see Figure 1 , Figure 2 and Figure 4 In some possible embodiments, the fixed bracket 31 has a plurality of first guide holes 311 along its circumference, and the first guide holes 311 extend radially along the fixed bracket 31. The rotating platform 32 is correspondingly disposed in the first guide holes 311, and the rotating platform 32 is slidably engaged with the first guide holes 311. The radial adjustment assembly 40 includes an adjustment plate 41 and a first driving member 42. The adjustment plate 41 is annular and disposed below the fixed bracket 31. The adjustment plate 41 has a plurality of second guide holes 411. The extension direction of the second guide holes 411 intersects the radial direction of the fixed bracket 31. One end of the second guide hole 411 is close to the center hole of the adjustment plate 41, and the other end is close to the edge of the adjustment plate 41. The second guide holes 411 correspond one-to-one with the first guide holes 311. The rotating platform 32 is slidably engaged with the second guide holes 411. The first driving member 42 is used to drive the adjustment plate 41 to rotate around its own axis.

[0063] In this embodiment, the adjusting plate 41 is rotatably disposed below the fixed bracket 31. The fixed bracket 31 has a first guide hole 311 arranged radially, and the adjusting plate 41 has a second guide hole 411 inclined at a certain angle to the first guide hole 311. The bottom of the rotating platform 32 has a sliding block that simultaneously slides with the first guide hole 311 and the second guide hole 411. The first driving member 42 drives the adjusting plate 41 to rotate clockwise or counterclockwise, so that the rotating platform 32 can slide back and forth along the first guide hole 311, thereby changing the radial distance of the air outlet mechanism 33. The second guide hole 411 can be an arc-shaped or elongated hole, with one end of the second guide hole 411 near the center of the adjusting plate 41 and the other end near the edge of the adjusting plate 41.

[0064] In this embodiment, the adjusting plate 41 is annular, and multiple second guide holes 411 are evenly distributed along the circumference of the adjusting plate 41. The sliding blocks of the rotating platform 32 are correspondingly fitted into the second guide holes 411. When the adjusting plate 41 rotates, it can simultaneously drive multiple rotating platforms 32 to move, thereby realizing the synchronous adjustment of multiple rotating platforms 32. Compared with setting a separate radial adjustment mechanism for each rotating platform 32, the structure is simple and the accuracy is high.

[0065] In this embodiment, the first driving component 42 is used to drive the adjustment plate 41 to rotate. The first driving component 42 can be a geared motor, hydraulic rotary motor or other rotating driving component that is connected to the rotating shaft of the adjustment plate 41. The rotating driving component is connected to the adjustment plate 41 through gear transmission, chain transmission, belt transmission or other means.

[0066] Please see Figure 1 In some possible embodiments, the outer periphery of the adjusting plate 41 is provided with a gear ring, and the first driving member 42 includes a drive motor and a gear. The drive motor is located on the fixed bracket 31, and the gear is located on the output shaft of the drive motor and meshes with the gear ring.

[0067] In this embodiment, a gear ring is provided on the outer periphery of the adjusting plate 41. The gear ring can be fixedly connected to the adjusting plate 41 as a whole by means of screws, welding, etc. The drive motor is located on the fixed bracket 31 and is located on one side of the gear ring. The output shaft of the drive motor is connected to a gear through a spline, etc. The gear meshes with the gear ring to drive the adjusting plate 41 to rotate.

[0068] In some possible embodiments, the tornado visualization device 1 further includes a height adjustment component for adjusting the vertical height of the fixed support 31. The height adjustment component may be a scissor lift, a starter lift, a hydraulic lift, a motor-driven screw jack, or a motor-driven rack and pinion mechanism, etc.

[0069] The height adjustment component is a vertically arranged lifting cylinder connected to the fixed bracket 31. One or more lifting cylinders can be installed as needed. When multiple cylinders are installed, they are spaced apart along the circumference of the fixed bracket 31 to ensure uniform force distribution and smooth lifting. In this embodiment, by setting the height adjustment component, the height of the power component 30 can be changed, thereby forming tornadoes of different shapes.

[0070] In some possible embodiments, the power assembly 30 is provided with two or more layers spaced apart from top to bottom. The tornado visualization device also includes multiple translation components, which correspond one-to-one with the power assembly 30. The translation components include a first translation mechanism and a second translation mechanism. The first translation mechanism is used to drive the corresponding fixed support 31 to move along a first horizontal direction, and the second translation mechanism is used to drive the corresponding fixed support 31 to move along a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0071] In this embodiment, the translation component includes a first translation mechanism and a second translation mechanism, which are used to adjust the position of the motion component in the x and y directions, respectively, so that the upper and lower power components 30 are staggered by a certain distance in the vertical direction, which can form a tornado with an inclined posture.

[0072] The first and second translation mechanisms can be hydraulic cylinders, electric telescopic rods, or other translation devices capable of moving in the x and y directions, connected to the fixed bracket 31. By setting up translation components, the tornado visualization device has more adjustment options, thereby creating tornadoes with more varied postures.

[0073] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present invention specification has recorded each combined embodiment and can support different combined embodiments.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
