Description

Technical Field

[0001] The utility model relates to the field of building smoke prevention and exhaust, in particular to a rainproof louver for an open air vent pavilion. Background Technique

[0002] In the design of underground projects, in order to minimize the impact on the urban landscape as much as possible, open low air vent pavilions usually become the preferred ventilation design scheme. The main advantage of this design lies in its low height, usually designed to be 1 meter to 1.2 meters above the ground, which can better integrate with the surrounding landscape, thus having less impact on the urban environment. However, although the open low air vent pavilion performs excellently in terms of aesthetics and landscape coordination, its design also brings some significant disadvantages, especially the problem of rain prevention is particularly prominent.

[0003] Due to the open mouth, the existing design of open low air vent pavilions has various serious defects. On rainy days, rainwater will enter the underground space unobstructed, forcing the project side to set up sump wells, drainage pumps and their corresponding supporting facilities in the underground space, increasing the project cost and the later operation and maintenance costs. In order to balance ventilation and rain prevention, rainproof louvers are usually set up in traditional designs to block the directly entering rainwater, but these designs often ignore the dust prevention effect. In addition, there are also deficiencies in the drainage design, and rainwater is likely to stay or seep into the louver surface, resulting in further leakage problems. Content of the Utility Model

[0004] In view of the above defects or requirements for improvement in the prior art solutions, the utility model provides a rainproof louver for an open air vent pavilion, which can effectively block rainwater and dust from entering the underground space while maintaining good ventilation effects by introducing an innovative combination of a diamond mesh and a drainage net.

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

[0006] A rainproof louver for an open air vent pavilion, comprising:

[0007] A louver frame, fixed on the upper part of the civil engineering base of the air vent of the open air vent pavilion;

[0008] A louver structure, arranged on the louver frame, including an upper louver structure and a lower louver structure. The upper louver structure includes a plurality of first blades and an upper louver installation cross beam for supporting and fixing the first blades; the lower louver structure includes a plurality of second blades and a lower louver installation cross beam for supporting and fixing the second blades; the first blades and the second blades are arranged alternately, so that the vertical projections of the blades of the upper louver structure and the lower louver structure can completely cover the air vent of the open air vent pavilion;

[0009] An arc-shaped wire mesh with an opening facing downwards is fixedly arranged between the first blades. A V-shaped drainage net is arranged below the wire mesh. The drainage net is installed at the edges of adjacent first blades. The drainage net is located above the second blades. Ventilation holes are evenly distributed on the wire mesh and the drainage net.

[0010] Preferably, the apertures of the ventilation holes on the wire mesh and the drainage net are the same.

[0011] Preferably, the first blade is semi-circular.

[0012] Preferably, the first blade is tile-shaped.

[0013] Preferably, the second blade is U-shaped.

[0014] Preferably, the lower louver installation cross beam includes a U-shaped groove, and the second blade is fixed in the U-shaped groove.

[0015] Preferably, the first blade and the second blade are inclined in the length direction and extend outside the louver frame at the front side air outlet, facilitating centralized drainage of rainwater.

[0016] Preferably, the slopes of the first blade and the second blade are designed to be 2% - 5%.

[0017] Preferably, the first blade and the drainage net are connected by a guiding plate. The guiding plate is a bent structure, which guides the rainwater towards the center of the second blade.

[0018] Preferably, the connection between the wire mesh and the first blade is a detachable connection method.

[0019] The beneficial effects of the present utility model are as follows: By setting upper and lower layers of louver structures and using the staggered arrangement design of the blades of the upper louver structure and the lower louver structure, the vertical projections of the upper and lower louvers can completely cover the air outlet of the open-air wind pavilion, and a sufficient ventilation area is formed on the vertical plane; By arranging a wire mesh between the first blades of the upper louver structure, it not only effectively blocks dust and fine particles from entering the interior of the open-air wind pavilion, but also ensures that the overall ventilation effect is not affected; By setting a V-shaped drainage net, the rainwater is effectively guided to the surface of the second blade of the lower louver structure, realizing rapid discharge of rainwater, avoiding the problem of rainwater staying or leaking on the louver surface. The drainage net and the first blade are connected by the bent structure of the guiding plate, enabling the rainwater to be centrally discharged, further enhancing the rainproof ability of the wind pavilion.

Detailed implementation manners

[0026] 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 a 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 those of ordinary skill in the art belong to the present invention.

[0027] In addition, the described features, structures or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to give a full understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present application.

[0028] Such as Figures 1-4As shown in the figure, this embodiment discloses a rain-proof louver for an open air vent, which includes a louver frame 1 and a louver structure. The louver frame 1 is fixed on the upper part of the civil engineering foundation 3 of the open air vent 2 of the open air vent, ensuring that the entire louver structure can be stably installed on the upper part of the air vent of the air vent, and effectively playing the functions of ventilation and rain protection without damaging the civil engineering structure.

[0029] The louver structure is arranged on the louver frame 1 and includes an upper louver structure 4 and a lower louver structure 5. The upper louver structure 4 includes a plurality of first blades 41 and an upper louver installation cross beam 42 for supporting and fixing the first blades 41. The first blades 41 are stably supported and fixed by the upper louver installation cross beam 42, ensuring the accurate position of each first blade 41 and enabling the entire upper louver structure 4 to effectively block the entry of rainwater. The lower louver structure 5 includes a plurality of second blades 51 and a lower louver installation cross beam 52 for supporting and fixing the second blades 51. The second blades 51 are also fixed by the lower louver installation cross beam 52. Specifically, the materials of the first blades 41 and the second blades 51 are aluminum alloy or other rigid materials.

[0030] The first blades 41 and the second blades 51 are arranged in an alternating manner, so that the vertical projections of the blades of the upper louver structure 4 and the lower louver structure 5 can completely cover the open air vent 2 of the open air vent. The alternating arrangement ensures the full coverage of the open air vent 2 of the open air vent without leaving gaps, effectively blocking the directly entering rainwater and enhancing the overall protection effect of the air vent.

[0031] An arc-shaped diamond mesh 43 with a downward opening is fixedly arranged between the first blades 41. A V-shaped drainage net 44 is arranged below the diamond mesh 43. The diamond mesh 43 is made of metal. Through the downward-opening design, it effectively blocks dust and other fine particles from entering the air vent interior without affecting ventilation. The drainage net 44 is made of a flexible fabric, installed at the edges of adjacent first blades 41 and above the second blades 51. This setting enables the drainage net 44 to guide rainwater into the second blades 51, ensuring the smooth discharge of rainwater and avoiding its retention in the louver structure. Ventilation holes 45 are evenly distributed on the diamond mesh 43 and the drainage net 44. These ventilation holes 45 ensure that while enhancing the protection function, the ventilation effect of the air vent is not affected, guaranteeing the normal operation of the ventilation system.

[0032] In some embodiments, the apertures of the ventilation holes 45 on the diamond mesh 43 and the drainage net 44 are the same, which not only ensures that the air flow can pass through these two mesh surfaces evenly, but also guarantees that the effects of dust prevention and rainwater guidance will not be affected by different apertures.

[0033] In some embodiments, the first blade 41 is semicircular, and its arc structure can effectively reduce wind resistance and provide a smooth path for the flow of rainwater. In other embodiments, the first blade 41 can also be designed as a tile shape, which further optimizes the waterproof performance. The tile-shaped design can better guide and discharge rainwater to prevent the occurrence of water accumulation.

[0034] In some embodiments, the second blade 51 is U-shaped, so that the second blade 51 not only has a strong structural strength, but also can form an effective water channel to smoothly guide and discharge rainwater. The lower louver mounting beam 52 includes a U-shaped groove, and this U-shaped groove structure provides a stable support for the fixation of the second blade 51, so that the second blade 51 can firmly maintain its position in the U-shaped groove, ensuring the overall stability and durability of the lower louver structure 5.

[0035] In this embodiment, the first blade 41 and the second blade 51 are inclined in the length direction, so that the blades can more effectively guide the flow of rainwater and extend outside the louver frame 1 at the front air outlet, thereby realizing centralized drainage of rainwater. In order to ensure that rainwater can be discharged smoothly, the slope of the first blade 41 and the second blade 51 is designed to be 2%-5%. The slope in this range can ensure the flow speed of rainwater on the blade surface without affecting the ventilation performance of the blade.

[0036] Furthermore, the first blade 41 and the drainage net 44 can be connected by a guide plate 46. The guide plate 46 adopts a bending structure. This design can accurately guide rainwater toward the center of the second blade 51, ensuring that rainwater will not flow into the open wind pavilion vent 2 through the ventilation area, but will be smoothly discharged through the second blade 51. The drainage net 44 adopts a flexible fabric with 30% openings, which can ensure its flexibility and adaptability when guiding rainwater and storing it, without affecting the overall louver structure, and give full play to its protective function in different states. The diamond mesh 43 and the first blade 41 adopt a detachable connection method. This design allows the diamond mesh 43 to be easily disassembled and cleaned, ensuring the continuity of the dustproof effect, and can be easily maintained and replaced when necessary.

[0037] In summary, the present utility model discloses a rainproof louver structure for an open air vent. Through the staggered arrangement of the upper louver structure and the lower louver structure, the comprehensive coverage of the air vent of the air vent is achieved, enhancing the protection performance. The inclined setting of the first blade and the second blade and its appropriate slope design effectively guide the concentrated discharge of rainwater, avoiding the occurrence of water accumulation. At the same time, by arranging the diamond mesh between the first blades, not only the dust prevention effect is improved, but also good ventilation performance is maintained; and the V-shaped drainage net further optimizes the drainage path of rainwater to ensure that rainwater can be discharged smoothly. The detachable connection method between the diamond mesh and the first blade provides a convenient maintenance means, enabling the system to still maintain high-efficiency protection and ventilation effects during long-term use. The structure design of the present utility model is reasonable and has a wide application prospect, especially suitable for underground spaces that require rain prevention, dust prevention and good ventilation.

[0038] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; under the idea of the present utility model, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present utility model.
