Description

Technical Field

[0001] This utility model belongs to the field of building environment and equipment engineering technology, specifically, it relates to a stadium ventilation and airflow guiding device. Background Technology

[0002] In high-density gathering places such as large stadiums, air quality control is particularly important due to the dense crowds. Traditional stadiums primarily rely on central fans for ventilation to meet basic indoor air quality requirements. However, large stadiums often feature irregular shapes, leading to significant differences in airflow across different areas. Using traditional central fans with fixed airflow directions can easily create airflow short-circuit or dead zones, resulting in uneven temperature distribution and the retention of pollutants such as carbon dioxide, heat, and odors, affecting the health and comfort of spectators. Furthermore, the concentrated crowds in spectator areas result in poor overall airflow uniformity, making it difficult for carbon dioxide and heat to dissipate quickly, further exacerbating air quality problems.

[0003] To address these issues, ventilation and airflow guiding devices have gained increasing attention. Existing technologies have attempted to improve airflow coverage by increasing the number of fans or optimizing their layout; however, their structural designs still struggle to flexibly adjust airflow direction and offer limited precision coverage for localized areas. Furthermore, these devices are typically installed in fixed locations, failing to adequately adapt to the complex architectural structures and dynamically changing crowd distribution within stadiums, resulting in suboptimal ventilation efficiency. In addition, existing equipment is susceptible to blockages and maintenance difficulties during long-term use, further limiting its practical application.

[0004] Against this backdrop, there is an urgent need to design a stadium ventilation and airflow guiding device that can be integrated under the seats and achieve flexible adjustment and precise coverage of airflow direction through air supply channels and adjustable airflow, thereby solving the aforementioned technical problems. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide a stadium ventilation and airflow guiding device to solve the problems of fixed ventilation and airflow guiding methods in traditional ventilation and airflow guiding devices, which can easily cause indoor airflow short circuits or dead corners during use, as well as the difficulty in quickly removing carbon dioxide and heat.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A stadium ventilation and airflow guiding device is installed on the underside of the tiered seating in the stadium's spectator area. It includes a main duct and an airflow guide. The main duct is arranged along the space under the tiered seating in the stadium's spectator area and is connected to the airflow guide through a branch pipe. The other end of the main duct is connected to a fan through a pipe connector.

[0010] In a preferred embodiment, a guide plate is provided on the inner side of the opening at one end of the main body of the flow guide that is close to the room, and the guide plate is provided with a plurality of flow guide holes.

[0011] In a preferred embodiment, a flow guiding slope is also formed inside the opening of the flow guide body on the outer side of the flow guide plate, and the inclined surface of the flow guiding slope forms an angle with the inner wall of the flow guide body.

[0012] In a preferred embodiment, the flow guiding mechanism includes a flow-blocking baffle, which is a circular plate structure that matches the flow guiding slope, and it matches a threaded sleeve located at the center of the flow guiding plate via a threaded post located at the center of the inner side.

[0028] The structure of the stadium ventilation and airflow guiding device will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] As per the instruction manual Figures 1-6 As shown, this utility model provides a technical solution: A stadium ventilation and airflow guiding device is installed on the underside of the tiered seating 1 in the stadium's spectator area. It includes a main pipe 2 and an airflow guide 4. The main pipe 2 is arranged along the space under the tiered seating 1 in the stadium's spectator area and is connected to the airflow guide 4 through a branch pipe 3. The other end of the main pipe 2 is connected to a fan 6 through a pipe connector 5, and the fan 6 provides ventilation power. The airflow guide 4 is installed in the mounting hole 7 on the lower side wall of the tiered seating 1 and is connected to the branch pipe 3 to form a closed-loop ventilation system for ventilation and airflow guiding inside the stadium.

[0034] In use, the fan 6 generates and provides ventilation power, allowing the air to be introduced into the stadium through the pipe connector 5, main pipe 2, branch pipe 3, and guide vane 4. Simultaneously, exhaust is performed in the reverse order, ensuring ventilation both inside and outside the stadium. This addresses the problems of traditional ventilation systems, such as fixed airflow patterns that can lead to short circuits or dead zones in the indoor airflow, and the difficulty in quickly removing carbon dioxide and heat.

[0035] In one specific implementation, such as Figure 1 and Figure 2 As shown, the mounting holes 7 are equidistantly arranged on the lower side wall of the stepped seat 1 and flush with the step surface, so that the step surface can be self-cleaned by the ventilation effect of the air guide 4 during use.

[0036] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the flow guide 4 includes an outer sleeve 21, a flow guide body 8, and a flow guiding mechanism disposed within the flow guide body 8. The outer sleeve 21 is pre-cast into the mounting hole 7 and connected to the branch pipe 3 via a tail flange; the flow guide body 8 is screwed into the outer sleeve 21 to facilitate replacement and maintenance of the flow guide body 8 according to actual usage requirements.

[0037] Specifically, an internal thread is provided on the inner side of the outer sleeve 21, which is used in conjunction with the external thread provided on the outer surface of the flow guide body 8 to realize the detachable connection between the outer sleeve 21 and the flow guide body 8.

[0038] Specifically, slots 12 are symmetrically provided on the end face of the flow guide body 8, which facilitates the rotation of the flow guide body 8 by inserting an external instrument into the slot 12 during use, and makes it easy to disassemble the flow guide body 8.

[0039] In one specific implementation, such as Figure 4 , Figure 5 and Figure 6 As shown, the main body 8 of the flow guide is a detachable sleeve installed inside the outer sleeve 21. A flow guide plate 10 is provided on the inner side of the opening at one end of the main body 8 near the room. The flow guide plate 10 is provided with a plurality of flow guide holes 22, which are used to guide the air on the left and right sides of the flow guide plate 10 through the flow guide holes 22 during use.

[0040] Specifically, a guide slope 14 is formed inside the opening of the guide body 8 outside the guide plate 10. The inclined surface of the guide slope 14 forms an angle with the inner wall of the guide body 8, which is used to guide the airflow to flow in a specific direction and at the same time prevent debris from being deposited inside the guide body 8.

[0041] In one specific implementation, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the flow guiding mechanism includes a flow-blocking baffle 9, which is a circular plate structure used in conjunction with the flow-guiding inclined surface 14. The baffle 9 is connected to a threaded sleeve 23 located at the center of the flow-guiding plate 10 via a threaded post 13 at its inner center. During use, the relationship between the baffle 9 and the flow-guiding plate 10 is adjusted by rotating the baffle 9 through the threaded connection between the threaded post 13 and the threaded sleeve 23, thus achieving initial adjustment of the airflow rate. Simultaneously, when the baffle 9 rests against the flow-guiding inclined surface 14, it can close the opening of the flow guide body 8, achieving closure when not in use and preventing long-term convection of internal and external air from causing weathering of indoor furnishings.

[0042] Specifically, a slot 20 is provided at the center of the front end face of the flow-blocking baffle 9. The slot 20 is used in conjunction with an external component, such as a screwdriver, to fix the external component during use so as to rotate the flow-blocking baffle 9.

[0043] Specifically, the flow guiding mechanism also includes a flow regulating plate 11, which is rotatably installed on the rear side of the flow obstruction baffle 9, passes through the threaded post 13, and is fixed by a threaded top sleeve 15 threadedly installed on the threaded post 13. After installation, the flow regulating plate 11 and the flow obstruction baffle 9 can rotate relative to each other.

[0044] More specifically, the flow regulating plate 11 is also provided with a plurality of second flow regulating holes 19, which are used in conjunction with the first flow regulating holes 16 provided on the flow obstruction baffle 9. In use, the relative overlap area of ​​the first flow regulating holes 16 and the second flow regulating holes 19 is adjusted by rotating the flow regulating plate 11, thereby achieving fine adjustment of the airflow rate.

[0045] More specifically, a guide post 18 is also provided on the flow regulating plate 11. The guide post 18 is used in conjunction with the arc-shaped guide groove 17 provided on the flow obstruction baffle 9 so that the relative overlap between the first flow regulating hole 16 and the second flow regulating hole 19 can be adjusted by pushing the guide post 18 to move in the guide groove 17 during use.

[0046] In actual operation, the stadium ventilation and airflow guiding device of this utility model generates ventilation power by controlling the operation of the fan 6, and then adjusts the ventilation of the stadium interior through the pipe connector 5, main pipe 2, branch pipe 3, and airflow guide 4. During use, the ventilation and airflow guiding efficiency can be adjusted according to needs. This solves the problems of traditional ventilation and airflow guiding devices, such as fixed ventilation and airflow guiding methods, which can easily cause short-circuiting or dead zones in the indoor airflow, and the difficulty in quickly removing carbon dioxide and heat.

[0047] Meanwhile, during use, the gas flow rate entering and exiting the guide vane can be adjusted by adjusting the relative positional relationship between the flow baffle 9 and the guide vane 10, and between the flow baffle 9 and the flow regulating plate, so as to ensure the ventilation and flow guiding efficiency of this device.

[0048] It should be noted that in this utility model, the fan 6 is existing technology known to those skilled in the art, and its model and power supply method can be selected according to specific needs during use, which will not be elaborated here.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
