Description

Technical Field

[0001] This invention relates to the field of vortex ring air supply technology, and in particular to a high-volume vortex ring air supply device. Background Technology

[0002] As a core ventilation device for large venues, the high-volume vortex ring air supply system achieves long-distance, large-area air supply through the entrainment effect of vortex ring airflow, requiring a single unit to have an air volume of ≥100,000 m³ / h. 3 Performance requirements include an air supply distance of ≥20m and an air outlet guide vane as a key component for controlling the airflow direction and diffusion angle.

[0003] Many existing vortex-type air supply devices rely on manual mechanical adjustment of the air outlet guide vane. These mechanisms are complex, involving multiple components and connections. Adjusting the vane angle or direction requires operators to spend considerable time and effort on tedious operations, such as loosening multiple screws, turning multiple knobs, or moving multiple linkages. In scenarios requiring frequent adjustments to the airflow direction, such as large event venues where airflow distribution requirements vary at different stages of an event, this complex adjustment method not only reduces work efficiency but also increases the operator's workload. Furthermore, delayed adjustments may negatively impact indoor ventilation. Therefore, we propose a high-fresh-volume vortex-type air supply device. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-volume vortex ring air supply device. This device addresses the issue that many existing vortex ring air supply devices rely on manual mechanical adjustment of the air outlet guide vane, resulting in a complex adjustment mechanism with multiple components and connections. Adjusting the angle or direction of the guide vane requires operators to spend considerable time and effort on tedious operations, such as loosening multiple screws, turning multiple knobs, or moving multiple linkages. In scenarios requiring frequent adjustments to the air supply direction, such as large event venues where airflow distribution requirements vary at different stages of an event, this complex adjustment method not only reduces work efficiency but also increases the workload of operators and may even affect indoor ventilation due to untimely operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-fresh-volume vortex air supply device, comprising: Vortex ring blower housing. An air inlet shroud is installed on one side of the vortex ring blower housing; The air guide plate adjustment structure is located on the casing of the vortex ring blower.

Multiple bevel gear rings are fixedly sleeved on the outer surface of the rotating rod. Multiple bevel gears are fixedly connected to the ends of the multiple rotating shafts near the rotating rod. The multiple bevel gears mesh with the corresponding bevel gear rings.

[0006] Preferably, four support rods are fixedly connected inside the vortex ring blower housing, and a mounting plate is fixedly connected to the end of each support rod away from the vortex ring blower housing. An exhaust fan is mounted on the mounting plate.

[0022] Vortex ring blower housing 1: As the main frame of the device, it is used to support and fix components such as air inlet hood 2, regulating box 5, support rod 12, honeycomb grid 9, and screen 6, forming a closed airflow channel to provide space for the generation and transmission of vortex ring airflow; Air inlet shroud 2: used to introduce outside air. Its internal spiral groove can guide the airflow to form a pre-swirling flow to reduce turbulence. At the same time, it can be detached by the insertion block 17 cooperating with the slot 18 of the vortex ring blower housing 1. Dust filter 3: It is fixedly installed inside the air inlet hood 2 to filter dust and impurities in the air and prevent particulate matter from entering the vortex blower housing 1 and affecting the operational stability of components such as the exhaust fan 13 and honeycomb grille 9. Mounting bracket 4: It is fixedly connected to the outer surface of the vortex ring blower housing 1. The four through holes on its top are used to fix the entire device in the hoisting position of the large venue to ensure the stability of the equipment during operation. Adjustment box 5: Both adjustment boxes 5 are fixed on the outer surface of the vortex ring blower housing 1. They are used to accommodate the end of the rotating shaft 10, the rotating rod 14, the bevel gear 15, the bevel gear ring 16 and other transmission components, providing a closed installation space for the air guide plate adjustment structure and protecting the transmission components from external interference. The baffle 6 is bolted to the side of the vortex ring blower housing 1 away from the air inlet hood 2 to prevent foreign objects from entering the device, while not obstructing the output of the vortex ring airflow after being adjusted by the guide plate 7. Guide vane 7: Fixed on the rotating shaft 10, multiple guide vanes 7 gradually shorten outward from the center of the vortex ring blower housing 1. The angle is adjusted by rotating the rotating shaft 10 to achieve the guidance and diffusion angle control of the rectified airflow, thereby adjusting the airflow direction and range of the vortex ring airflow. Stepper motor 8: Fixedly installed on the top of the corresponding adjustment box 5, serving as the power source for the air guide plate adjustment structure. Its output end can drive the rotating rod 14 to rotate, providing driving force for the angle adjustment of the air guide plate 7. Honeycomb grille 9: Bolted inside the vortex ring blower housing 1, its hexagonal unit structure can rectify the airflow delivered by the exhaust fan 13, reduce the turbulence intensity, and make the airflow form a uniform beam, laying the foundation for the precise air guidance of the subsequent guide plate 7. Rotating shaft 10: Multiple rotating shafts 10 are rotatably connected inside the vortex ring blower housing 1, with both ends extending into the corresponding adjustment box 5. One end is connected to the guide plate 7, and the other end is fixed to the bevel gear 15. They can rotate under the meshing transmission of the bevel gear 15 and the bevel ring 16, thereby driving the guide plate 7 to adjust the angle. Mounting plate 11: It is fixed inside the vortex ring blower housing 1 by four support rods 12 and is used to install the exhaust fan 13, providing a stable mounting base for the exhaust fan 13. Support rod 12: One end of the four support rods 12 is fixedly connected to the vortex ring blower housing 1, and the other end is fixedly connected to the mounting plate 11. They are used to suspend and fix the mounting plate 11 and the exhaust fan 13 inside the vortex ring blower housing 1, so as to avoid the exhaust fan 13 from directly contacting the housing and generating vibration and noise during operation. Exhaust fan 13: Installed on mounting plate 11, it provides power for airflow after starting and can deliver the air pre-treated by air inlet shroud 2 to the honeycomb grid 9 in the middle section of the vortex blower casing 1; Rotating rod 14: One end of it is fixedly connected to the output end of stepper motor 8, and multiple bevel gear rings 16 are fixedly sleeved on its outer surface. It can rotate under the drive of stepper motor 8, and drive rotating shaft 10 to rotate synchronously through the meshing of bevel gear 15 with bevel gear 16. Bevel gear 15: Fixed at one end of the rotating shaft 10 near the rotating rod 14, it meshes with the corresponding bevel gear ring 16 on the rotating rod 14, and can transmit the rotational motion of the rotating rod 14 to the rotating shaft 10 to realize power transmission; The bevel ring 16 is fixedly sleeved on the outer surface of the rotating rod 14 and meshes with the bevel gear 15 on the rotating shaft 10. It rotates under the drive of the rotating rod 14 and drives multiple rotating shafts 10 to rotate synchronously through gear meshing, ensuring the consistency of the adjustment of the guide plate 7. Insert 17: All four inserts 17 are fixedly connected to the air inlet cover 2 and are inserted into the slots 18 of the vortex ring blower housing 1 and fixed with bolts to realize the detachable connection between the air inlet cover 2 and the vortex ring blower housing 1, ensuring the sealing and stability of the air inlet channel. Slot 18: Located on the side of the vortex blower housing 1 near the air inlet shroud 2, it is used to accommodate the insert 17. The insert 17 and bolts are used to fix the air inlet shroud 2 and ensure the airtightness of the connection between the air inlet shroud 2 and the housing.

[0023] Example 1: like Figure 1-7 As shown, large conference centers have different requirements for indoor airflow distribution and ventilation when hosting conferences of different sizes and types.

[0024] This advanced air volume vortex air supply device is installed at the top of the conference center. The stepper motor 8 receives signals from the control system and drives the rotating rod 14 to rotate. Multiple bevel gear rings 16 on the rotating rod 14 drive multiple bevel gears 15 that mesh with them to rotate, thereby causing multiple rotating shafts 10 to rotate and achieving precise adjustment of the angle of multiple guide plates 7.

[0025] Because the deflector plate 7 gradually shortens outward from the center of the vortex ring blower casing 1, this design allows for more flexible control of the airflow direction and intensity in different areas when adjusting the angle. During large lectures, the deflector plate 7 can be adjusted to concentrate the airflow towards the audience area, allowing fresh air to quickly reach densely populated areas. During group discussions, the angle of the deflector plate 7 can be adjusted to distribute the airflow evenly, creating a comfortable communication environment, reducing the workload of operators, and responding promptly to the ventilation needs of different scenarios.

[0026] Example 2: Underground parking lots are typically large spaces with poor ventilation, leading to the accumulation of vehicle exhaust fumes. The concentration of exhaust fumes may vary in different areas, requiring adjustments to the exhaust direction and intensity based on the specific conditions to quickly and effectively remove harmful gases and improve air quality.

[0027] Install this vortex ring air supply device in a suitable location in the underground parking lot. The exhaust fan 13 operates to generate air volume, which is rectified by the honeycomb grid 9 to form a stable vortex ring airflow.

[0028] When the exhaust gas concentration is high in a certain area, the stepper motor 8 controls the guide plate 7 to direct the airflow to that area, accelerating the discharge of harmful gases. At the same time, the spiral groove design inside the air intake hood 2 helps to enhance the air intake effect, allowing fresh air to enter the device more quickly. The dust filter 3 can filter dust and other impurities in the air, ensuring that the air entering the device is clean, realizing directional exhaust, and improving the air quality of the underground parking lot more efficiently.

[0029] By adjusting the angle of the guide vane 7, the vortex airflow is evenly distributed within the greenhouse, providing a suitable airflow environment for plants in different locations. For example, for plants near the vents, the guide vane 7 is adjusted to a smaller angle to reduce airflow intensity; for plants in the middle of the greenhouse, the angle of the guide vane 7 is adjusted to enhance airflow. Simultaneously, the stable airflow generated by the exhaust fan 13 and the rectifying effect of the honeycomb grille 9 ensure the stability and uniformity of the airflow. Compared to traditional greenhouse ventilation methods, this device can precisely adjust the airflow distribution according to the actual needs of the plants, creating a better environment for plant growth and improving crop yield and quality.

[0030] Furthermore, when using this device, outside air enters the equipment through the air inlet hood 2. The dust filter 3 inside the air inlet hood 2 filters dust and impurities in the air, preventing particulate matter from entering the equipment and affecting operational stability. At the same time, the spiral groove inside the air inlet hood 2 guides the airflow to form a pre-swirling flow, reducing turbulence disturbance after the airflow enters the vortex ring blower housing 1. The air inlet hood 2 is bolted to the slot 18 of the vortex ring blower housing 1 through the insert block 17, ensuring the sealing and stability of the air inlet channel.

[0031] The mounting plate 11 is fixed inside the vortex ring blower housing 1 by four support rods 12. After the exhaust fan 13 on the mounting plate 11 is started, it provides power to send the pre-treated airflow into the middle section of the vortex ring blower housing 1. The airflow first passes through the honeycomb grid 9, whose hexagonal unit structure rectifies the airflow, reduces the turbulence intensity, and makes the airflow form a uniform beam. When the rectified airflow reaches the guide plate 7 area, the stepper motor 8 is started when the guide plate 7 is adjusted. The stepper motor 8 is fixed to the top of the adjustment box 5, and its output end drives the rotating rod 14 to rotate. Multiple bevel tooth rings 16 on the rotating rod 14 rotate synchronously. The bevel gear ring 16 meshes with the bevel gear 15 at the end of the rotating shaft 10, driving multiple rotating shafts 10 to rotate synchronously inside the vortex ring blower housing 1, thereby driving the guide plate 7 fixed on the rotating shaft 10 to adjust the angle, and the vortex ring airflow adjusted by the guide plate 7 is sent out from the end of the vortex ring blower housing 1.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
