Description

Technical Field

[0001] The utility model relates to the field of building smoke prevention and exhaust, in particular to an open wind pavilion with adjustable shutters. Background Art

[0002] In underground engineering design, open, low-wind pavilions are often the preferred ventilation solution to minimize the impact on the urban landscape. The primary advantage of this design lies in its low height, typically 1 to 1.2 meters above ground level, which allows it to blend well with the surrounding landscape and thus minimize its impact on the urban environment. However, while these open, low-wind pavilions offer excellent aesthetics and landscape integration, they also come with some significant drawbacks, particularly in terms of rain protection.

[0003] The open wind pavilion design in the prior art usually adopts a fixed louver structure. Although this design is simple, it has significant defects. The fixed louver structure cannot be adjusted according to changes in the external environment. Therefore, under severe weather conditions, rainwater, dust and other foreign matter can easily enter the underground space through the open wind pavilion, causing potential safety hazards. In addition, the fixed louver structure cannot achieve complete closure of the wind pavilion, and thus cannot effectively prevent rainwater backflow and the intrusion of external pollutants in extreme weather. Although some designs in the prior art have introduced adjustable louver structures, these adjustable louver structures often find it difficult to strike a balance between protective performance and ventilation efficiency. Utility Model Content

[0004] In response to the above defects or improvements required in the existing technical solutions, the utility model provides an open wind pavilion with adjustable shutters. By introducing a height adjustment component, the shutter structure can flexibly adjust the height according to the external environment and actual needs, thereby achieving effective closing and opening of the wind pavilion.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An open wind pavilion with adjustable shutters, comprising:

[0007] The louver frame is fixed on the upper part of the civil foundation of the open wind pavilion vent;

[0008] The louver structure is provided on the louver frame, and includes an upper louver structure, a lower louver structure and side louvers. The side louvers are located at the left air outlet, the right air outlet, the front air outlet and the rear air outlet of the louver frame, namely the left louver, the right louver, the front louver and the rear louver;

[0009] The bottoms of both ends of the lower louver structure are fixed with vertically arranged mounting rods, namely a first mounting rod and a second mounting rod, and both ends of the plurality of front louvers are rotatably connected to the first mounting rod and the second mounting rod respectively through a rotating shaft;

[0010] A height adjustment component controls the upper louver structure and the lower louver structure to move downward relative to the louver frame to the bottom of the louver frame to close the open air pavilion air outlet.

[0011] Preferably, the rotating shaft is located at the center of the front louver, and the two ends of the front louver are connected by a connecting rod. When the lower louver structure moves downward, the mounting rod drives the front louver to move downward. When the end of the front louver close to the outside abuts against the civil engineering base of the open wind pavilion air outlet, it flips over and enters the open wind pavilion air outlet along the mounting rod.

[0012] Preferably, the rotating shaft is located at the inner end of the front louver, and the centers of the front louver are connected by a connecting rod. When the lower louver structure moves downward, the mounting rod drives the front louver to move downward. When the outer end of the front louver abuts against the civil engineering base of the open wind pavilion vent, it flips over and enters the open wind pavilion vent along with the mounting rod.

[0013] Preferably, the upper louver structure includes a plurality of first blades and an upper louver mounting beam for supporting and fixing the first blades.

[0014] Preferably, the lower louver structure includes a plurality of second louvers and a lower louver mounting beam for supporting and fixing the second louvers.

[0015] Preferably, the first blades and the second blades are staggered so that the vertical projections of the blades of the upper louver structure and the lower louver structure can completely cover the air outlet of the open wind pavilion.

[0016] Preferably, the first blade and the second blade are arranged obliquely in the length direction, and extend out of the louver frame at the front air outlet to facilitate centralized drainage of rainwater.

[0017] Preferably, the height adjustment assembly is located in the cover of the left air outlet and the right air outlet of the louver frame.

[0018] Preferably, the height adjustment assembly includes a motor and a lifting rod driven to rotate by the motor, and both ends of the upper louver mounting beam and the lower louver mounting beam are respectively sleeved on the lifting rod through sliders.

[0019] Preferably, the lifting rod is provided with an external thread, and the sliding block is provided with an internal thread.

[0020] The beneficial effects of the present utility model are as follows: when the rainfall is heavy or there is a possibility of rainwater backflow, the height adjustment component can control the upper louver structure to descend to fit tightly with the lower louver structure to form a closed structure, thereby effectively preventing ground water from backflowing into the underground space. This design is not only suitable for rain protection needs under normal rainfall conditions, but also provides reliable flood protection in extreme weather, greatly improving the safety of the underground space. By arranging side louvers on all four sides of the main frame, the wind rate of the wind pavilion is significantly improved, ensuring that the wind pavilion can maintain good ventilation. In addition, the design of the front side louvers does not affect the movement of the upper louver structure and the lower louver structure, ensuring the smoothness of the adjustment process and the stability of the wind pavilion structure.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the present invention.

[0033] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0034] like Figure 1-9 As shown, this embodiment discloses an open wind pavilion with adjustable louvers, including a louver frame 1 and a louver structure. The louver frame 1 is fixed to the upper part of the civil engineering base 3 of the air outlet 2 of the open wind pavilion, and effectively performs ventilation and rain protection functions without damaging the civil engineering structure. The louver structure is installed on the louver frame 1, including an upper louver structure 4, a lower louver structure 5 and side louvers 6. The side louvers 6 are arranged at the left air outlet, right air outlet, front air outlet and rear air outlet of the louver frame 1, which are respectively the left louver 61, the right louver 62, the front louver 63 and the rear louver 64. The side louvers 6 arranged in this way can significantly improve the wind passing rate of the wind pavilion, ensuring that the pavilion can still maintain a good ventilation effect.

[0035] Vertically mounted mounting rods 7 are fixed to the bottoms of both ends of the lower louver structure 5. The mounting rods 7 are respectively a first mounting rod 71 and a second mounting rod 72. The ends of the plurality of front louvers 63 are rotatably connected to the first mounting rod 71 and the second mounting rod 72 via a rotating shaft 65, allowing the front louvers 63 to be moved when needed, ensuring that the adjustment function of the lower louver structure 5 is not affected. When it is necessary to completely close the open air pavilion vent 2, the front louvers 63 can be smoothly stored.

[0036] In the ventilation state, the upper louver structure 4 and the lower louver structure 5 maintain a distance from each other, and the height adjustment component 8 is used to control the upper louver structure 4 and the lower louver structure 5 to move downward relative to the louver frame 1 to the bottom of the louver frame 1 to completely seal the open air pavilion vent 2, which is now in the closed state. Through this height adjustment component 8, the upper louver structure 4 and the lower louver structure 5 can be flexibly adjusted according to environmental conditions, thereby effectively preventing rainwater or other foreign matter from entering the underground space, especially in inclement weather, ensuring the safety of the underground space.

[0037] like Figure 4-5 As shown, in one embodiment, the rotation axis 65 is located at the center of the front louver 63. The two ends of the front louver 63 are connected by a connecting rod 9. This design ensures that the front louver 63 remains stable during movement. When the lower louver structure 5 moves downward, the mounting rod 7 drives the front louver 63 downward along with it. When the outer end of the front louver 63 abuts the civil foundation 3 of the open wind pavilion vent 2, the front louver 63 flips over and enters the open wind pavilion vent 2 along with the mounting rod 7.

[0038] like Figure 6-7 As shown, in another embodiment, the rotation axis 65 is located at the inner end of the front louver 63, and the centers of the front louvers 63 are connected by a connecting rod 9. This arrangement also allows the front louvers 63 to remain stable during movement. When the lower louver structure 5 moves downward, the mounting rod 7 drives the front louvers 63 downward. When the outer end of the front louver 63 abuts the civil foundation 3 of the open wind pavilion vent 2, the front louver 63 flips over and enters the open wind pavilion vent 2 along with the mounting rod 7.

[0039] Through the above design, it is ensured that the front side louvers 63 can be smoothly stored inside the wind pavilion during the closing process of the open wind pavilion air outlet 2, ensuring that the entire wind pavilion achieves good protection effect in the closed state, and the front side louvers 63 do not affect the normal operation of other structures.

[0040] like Figure 8-9As shown, the louver structure can be in a ventilating state and a closed state. The upper louver structure 4 includes a plurality of first blades 41 and an upper louver mounting crossbeam 42 for supporting and securing the first blades 41. The first blades 41 are stably supported and secured by the upper louver mounting crossbeam 42, ensuring the accurate positioning of each first blade 41 and enabling the entire upper louver structure 4 to effectively block rainwater ingress. The lower louver structure 5 includes a plurality of second blades 51 and a lower louver mounting crossbeam 52 for supporting and securing the second blades 51. The second blades 51 are also secured by the lower louver mounting crossbeam 52. The first blades 41 and the second blades 51 are staggered so that the vertical projections of the blades of the upper louver structure 4 and the lower louver structure 5 completely cover the open air pavilion vent 2. The staggered arrangement ensures full coverage of the open air pavilion vent 2 without leaving any gaps. In the ventilating state, it effectively blocks direct rainwater ingress and enhances the overall protective effect of the air pavilion. In the closed state, the first blades 41 and the second blades 51 cooperate to seal the open air pavilion vent 2.

[0041] In this embodiment, the first blades 41 and the second blades 51 are tilted in their lengthwise direction, allowing the blades to more effectively guide the flow of rainwater. The blades extend beyond the louver frame 1 at the front vents, thereby achieving centralized drainage of rainwater. To ensure smooth drainage of rainwater, the slope of the first blades 41 and the second blades 51 is designed to be 2%-5%. This slope range ensures a high flow rate of rainwater on the blade surface without affecting the ventilation performance of the blades.

[0042] like Figure 9 As shown, in this embodiment, the height adjustment assembly 8 is located within the housing 11 of the left and right air outlets of the main frame 1. This design can effectively protect the height adjustment assembly 8 from the influence of the external environment and ensure its stable operation. The height adjustment assembly 8 includes a motor 81 and a lifting rod 82. The motor 81 adjusts the height of the upper louver mounting beam 42 and the lower louver mounting beam 52 by rotating the lifting rod 82. The ends of the upper louver mounting beam 42 and the lower louver mounting beam 52 are respectively mounted on the lifting rod 82 through sliders 83. When the motor 81 drives the lifting rod 82 to rotate, the slider 83 moves up and down along the lifting rod 82, thereby driving the upper louver mounting beam 42 and the lower louver mounting beam 52 to move downward synchronously to achieve the purpose of height adjustment. The lifting rod 82 is provided with an external thread, and the slider 83 is provided with an internal thread that matches it. When the motor 81 is activated, the lifting rod 82 rotates, and through the threaded drive, the slider 83 moves up and down along the lifting rod 82, thereby driving the upper louver mounting beam 42 and the lower louver mounting beam 52 to move synchronously, achieving the up and down adjustment of the louver structure. This threaded drive design not only ensures the stability and accuracy of adjustment, but also effectively prevents the louver structure from slipping or loosening during adjustment.

[0043] In summary, the utility model discloses a rainproof louver structure for an open wind pavilion. By introducing a height adjustment component 8, the louver structure is flexibly adjusted, and can be moved up and down according to the external environment and actual needs, thereby effectively realizing the closing and opening of the open wind pavilion. This structure not only enhances the protective performance, but also, especially under heavy rainfall or extreme weather conditions, can form a closed structure by tightly fitting the upper louver structure 4 and the lower louver structure 5, effectively preventing ground water from flowing back. In addition, by arranging side louvers 6 around the louver frame 1, the wind rate of the wind pavilion is significantly improved, ensuring that good ventilation effects can still be maintained under different weather conditions. The design of the front side louvers 63 does not affect the adjustment and storage process of the louver structure, further improving the stability and adaptability of the overall system. The utility model has a reasonable structure and complete functions, and is widely applicable to the ventilation and protection needs of various underground spaces.
