Description

Technical Field

[0001] This utility model relates to ventilation structures, and more specifically to a warehouse ventilation structure. Background Technology

[0002] For warehouses, especially those storing grains, chemical raw materials, textiles, electronic products, or other goods requiring high air circulation, the internal air quality and ventilation are crucial. Good ventilation can effectively regulate the temperature and humidity inside the warehouse, preventing goods from becoming moldy, spoiled, or clumping due to high temperature and humidity. At the same time, it can remove harmful gases or dust generated by the volatilization of materials, ensuring storage safety and quality. Typically, air inlets and outlets are installed at high and low points on warehouse walls, relying on the temperature difference and wind pressure between indoors and outdoors for air exchange. While this structure is inexpensive and requires no energy, its ventilation effect is entirely dependent on natural conditions and is unstable. In windless weather or when the temperature difference between indoors and outdoors is small, air circulation is extremely weak, easily creating ventilation dead zones inside the warehouse, especially in the central area and areas with dense stacking of goods, where the air is almost stagnant, leading to localized excessive temperature and humidity. Forced ventilation using fans is employed. While more efficient than natural ventilation, it typically has significant drawbacks. First, simple air supply systems merely inject outdoor air into the warehouse in one direction, resulting in a linear airflow that fails to effectively agitate and replace the stagnant air throughout the warehouse space, especially between complex shelving units. This leads to uneven mixing of fresh and old air, creating a "short-circuit" effect where fresh air flows directly from the inlet to the outlet without adequately reaching the goods area. Second, achieving ideal overall ventilation often requires multiple fans, resulting in complex layouts, high energy consumption, and increased operating costs. In summary, existing warehouse ventilation structures, whether natural or mechanical, generally suffer from a core problem: they cannot actively and effectively agitate the air in every corner of the warehouse while introducing fresh air, resulting in insufficient air circulation, low ventilation efficiency, and the potential for creating areas of localized environmental degradation. Utility Model Content

[0003] The purpose of this invention is to provide a warehouse ventilation structure that can introduce outdoor air into the warehouse while simultaneously agitating the air inside, increasing airflow and improving ventilation.

[0004] The objective of this utility model is achieved through the following technical solution: A warehouse ventilation structure includes a ventilation duct, a rotating cavity rotatably connected to the ventilation duct, and a diffuser duct fixedly connected to the rotating cavity. The rotating cavity can rotate on the ventilation duct, driving the diffuser duct to rotate, thereby causing the diffuser duct to agitate the air inside the warehouse. The ventilation duct is provided with a connecting hole, and the ventilation duct is connected to the rotating cavity through the connecting hole, and the rotating cavity is connected to the air dissipation duct. The ventilation duct is fixedly connected to a mounting bracket; A fan is rotatably connected to the ventilation duct, and a drive motor that drives the fan to rotate is fixedly connected to the ventilation duct. A linkage shaft is fixedly connected to the fan; The rear end of the ventilation duct is fixedly connected to a mounting base, and the linkage shaft is rotatably connected to the mounting base. A drive gear is fixedly connected to the linkage shaft; A driven gear is rotatably connected to the mounting base, and a gear ring is rotatably connected to the mounting base. The driving gear and the driven gear mesh for transmission, and the driven gear and the gear ring mesh for transmission; Blades are fixedly connected between the gear ring and the air duct.

[0005] The beneficial effects of this utility model are as follows: The ventilation duct is used to ventilate the warehouse. At the same time, the rotating cavity can rotate around the ventilation duct, which in turn drives the air distribution duct to rotate, thereby agitating the air in the warehouse, increasing the air flow and improving the ventilation effect.

[0009] The present invention will now be described in further detail with reference to the accompanying drawings.

[0010] like Figures 1 to 7 As shown below, the structure and function of a warehouse ventilation system will be described in detail. A warehouse ventilation structure includes a ventilation duct 11, a rotating cavity 31 rotatably connected to the ventilation duct 11 via a bearing, and a diffuser duct 32 fixedly connected to the rotating cavity 31 via screws. The rotating cavity 31 can rotate on the ventilation duct 11, driving the diffuser duct 32 to rotate, so that the diffuser duct 32 agitates the air in the warehouse. The ventilation duct 11 is provided with a connecting hole 13, and the ventilation duct 11 is connected to the rotating cavity 31 through the connecting hole 13. The rotating cavity 31 is connected to the air dissipation duct 32. When using, such as Figure 1 As shown, one end of the ventilation duct 11 is connected to the outside, and the other end is located indoors. The ventilation duct 11 ventilates the warehouse. The airflow enters the rotating cavity 31 through the ventilation duct 11, then enters the air distribution duct 32 through the rotating cavity 31, and finally enters the warehouse through the air distribution duct 32. At the same time, the air distribution duct 32 is driven to rotate, causing the rotating cavity 31 to rotate on the ventilation duct 11. As the air distribution duct 32 rotates, it agitates the air in the warehouse, increasing the airflow and ventilation effect. It also continuously changes the position of the outside air entering the warehouse, achieving uniform ventilation. Furthermore, a mounting bracket 14 is fixedly connected to the ventilation duct 11 by screws; a hole is made in the warehouse wall for the ventilation duct 11 to pass through, so that one end of the ventilation duct 11 extends into the outside of the warehouse through the hole, and the mounting bracket 14 fits against the warehouse wall, thereby completing the installation and fixation of the ventilation duct 11. A fan 22 is rotatably connected to the ventilation duct 11 via bearings. A drive motor 21 for driving the fan 22 is fixedly connected to the ventilation duct 11 via screws. The drive motor 21 is preferably a servo motor. When the drive motor 21 is started, the output shaft of the drive motor 21 begins to rotate. The output shaft of the drive motor 21 drives the fan 22 to rotate, thereby forcibly blowing external air into the ventilation duct 11 to achieve ventilation. Furthermore, in order to drive the ventilation duct 32 to rotate continuously; The fan 22 is fixedly connected to the linkage shaft 23 by screws; The rear end of the ventilation duct 11 is fixedly connected to the mounting base 12 by screws, and the linkage shaft 23 is rotatably connected to the mounting base 12 by bearings. A drive gear 41 is fixedly connected to the linkage shaft 23 by screws; A driven gear 42 is rotatably connected to the mounting base 12 via a bearing, and a gear ring 43 is rotatably connected to the mounting base 12 via a bearing. The driving gear 41 and the driven gear 42 mesh for transmission, and the driven gear 42 and the gear ring 43 mesh for transmission. When fan 22 rotates, it drives linkage shaft 23 to rotate, which in turn drives drive gear 41 to rotate. Drive gear 41 then drives driven gear 42 to rotate, which in turn drives gear ring 43 to rotate. Since the diameter of gear ring 43 is larger than that of drive gear 41, speed reduction is achieved. Blades 44 are fixedly connected between gear ring 43 and air duct 32 by screws. When gear ring 43 rotates, it drives air duct 32 to rotate, thus agitating the air, increasing airflow in the warehouse, and improving ventilation. At the same time, it continuously changes the position of external air entering the warehouse, achieving uniform ventilation. Furthermore, the rotation of blade 44 further enhances the airflow within the warehouse, increasing ventilation.
