Description

Technical Field

[0001] The present invention relates to the technical field of building ventilation and drainage, and in particular to a fully automatic open wind pavilion with intelligent rain and flood prevention shutters. Background Art

[0002] In underground engineering design, open, low-wind pavilions are often the preferred ventilation solution to minimize 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 seamlessly with the surrounding landscape and minimize impact on the urban environment. However, while these pavilions offer excellent aesthetics and landscape integration, they also come with some significant drawbacks, particularly in terms of rain and flood control.

[0003] The existing open low-wind pavilion design has many serious defects due to its exposure. First, on rainy days, rainwater will enter the underground space without hindrance, forcing the project party to set up a water collection well, drainage pumps and their corresponding supporting facilities in the underground space, which increases the cost of the project and the subsequent operation and maintenance costs. Secondly, when the amount of rainwater is large, the drainage pump cannot discharge all the rainwater in time, which may cause the rainwater to spread to other areas of the underground space, posing a potential safety hazard. Especially in extreme weather conditions, since the height of the wind pavilion is relatively low from the ground, rainwater may flow back into the underground space, causing serious safety risks. Although the existing technology also uses upper and lower louvers to block rainwater from entering through the structure of the louvers, this type of design often has the problem of low wind rate and cannot meet the requirements of ventilation standards. The low wind rate will lead to insufficient ventilation effect of the wind pavilion, affecting the air circulation in the underground space, and thus adversely affecting the performance of the entire ventilation system. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention proposes a fully automatic open wind pavilion intelligent rain and flood prevention shutter. Through the design of the shutter, not only the wind rate is significantly improved, ensuring that the ventilation effect meets the standard requirements, but also its main frame design can be directly placed on the upper part of the civil engineering base of the open wind pavilion air outlet without destroying the existing civil engineering structure, which greatly simplifies the installation process, reduces engineering costs and improves the safety and reliability of the system.

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

[0008] Preferably, the first blade and the second blade are arranged obliquely in the length direction, and extend out of the main frame at the front air outlet to facilitate centralized drainage of rainwater.

[0009] Preferably, the main frame includes a bottom beam fixedly arranged at the bottom of the front air outlet. In the flood prevention state, the height adjustment component controls the lower louver mounting beam to move downward until it contacts the bottom beam.

[0010] Preferably, an arc-shaped diamond mesh with the opening facing downward is fixed between the first blades, and a V-shaped drainage mesh is provided below the diamond mesh. The drainage mesh is installed at the edge of the adjacent first blade. In the normal state, the drainage mesh is located above the second blade, and in the flood prevention state, the drainage mesh is located inside the second blade.

[0011] Preferably, the first blade and the drainage net are connected by a guide plate, and the guide plate is a bent structure to guide rainwater toward the second blade. The drainage net is made of a flexible fabric with 30% open holes.

The motor drives the lifting rod to rotate, and the slider drives the upper louver mounting beam and the lower louver mounting beam to move downward.

[0015] Preferably, the height adjustment component includes a control module, which has two adjustment modes: automatic mode and manual mode. In the automatic mode, a liquid level sensor is provided on the side wall of the civil engineering base.

When the staff believes that there is a safety hazard, they can send a signal to the control module through the manual control button to manually control the motor to perform the operation.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) The present invention provides a two-layer louver structure, with the blades of the upper and lower louvers arranged in an interlaced manner, so that the vertical projections of the upper and lower louvers can completely cover the vents of the open wind pavilion and form a sufficient ventilation area on the vertical plane. By providing side louvers on all four sides of the main frame, the wind passing rate of the wind pavilion is significantly improved, ensuring that the wind pavilion can still maintain a good ventilation effect under different weather conditions, and the front side louvers do not affect the movement of the upper and lower louver structures. The main frame design of the present invention can be directly placed on the upper part of the civil engineering base of the open wind pavilion vent without destroying the existing civil engineering structure, simplifying the installation process and reducing engineering costs.

[0018] (2) The present invention uses a height adjustment component that can control the upper louver structure to descend to closely fit the lower louver structure in the event of heavy rainfall or the possibility of rainwater backflow, forming a closed structure and effectively preventing surface 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. The height adjustment component adopts an advanced intelligent control system to achieve fully automatic intelligent adjustment of the wind pavilion louver structure, with two adjustment modes: automatic mode and manual mode, providing greater flexibility.

[0019] (3) The present invention sets a diamond mesh between the blades of the upper louver structure, which has a good dust-proof function, effectively prevents dust from entering the interior of the wind pavilion, and keeps the ventilation system clean. The flexible guide net is set below the diamond mesh, which can effectively guide rainwater to the lower louver structure for drainage treatment. When the upper and lower louver structures cover the open wind pavilion air outlet, the guide net can be stored in the second blade, ensuring the compactness of the system without affecting the overall rain and flood prevention effect.

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] See also Figure 1-10This embodiment provides a fully automatic intelligent rain and flood prevention louver for an open wind pavilion, comprising a main frame 1 and a louver structure. The main frame 1 is mounted above the civil engineering base 3 of the open wind pavilion's vent 2. The main frame 1 is a monolithic structure capable of stably supporting the entire louver structure. During installation, the louver structure can be directly placed at the existing open wind pavilion's vent 2 without destroying the civil engineering structure. The louver structure comprises an upper louver structure 4, a lower louver structure 5, and side louvers 6. The louver structure is mounted on the main frame 1. The blades of the upper and lower louver structures 4 and 5 are staggered so that their vertical projections completely cover the open wind pavilion's vent 2, effectively preventing rainwater from entering the underground space.

[0035] The upper louver structure 4, the lower louver structure 5 and the main frame 1 are connected by a fully automatically controlled height adjustment component 7, which can flexibly adjust the height of the louver structure between the daily state and the flood control state. In the daily state, the upper louver structure 4 and the lower louver structure 5 maintain a certain spacing in the vertical direction, so that the upper and lower staggered blades form a ventilation area on the vertical plane to meet the normal wind flow requirements of the open wind pavilion. At the same time, the design can also guide rainwater along the length of the blades and drain it from the front air outlet, thereby effectively draining rainwater while maintaining good ventilation. In the flood control state, the upper louver structure 4 and the lower louver structure 5 are controlled by the height adjustment component 7 to move downward relative to the main frame 1 until both move to the bottom of the main frame 1, thereby closing the open wind pavilion air outlet 2 and preventing ground water from flowing back.

[0036] Side louvers 6 are arranged around the main frame 1, namely at the left, right, front, and rear vents, and are represented by left louver 61, right louver 62, front louver 63, and rear louver 64, respectively. These louvers are fixed to the main frame 1, ensuring air circulation at the left, right, and rear vents, improving the overall airflow rate. Front louver 63, located below the lower louver structure 5, can be retracted into the open pavilion vent 2 as the lower louver structure 5 moves downward, without affecting the movement of the upper louver structure 4 and lower louver structure 5, further optimizing space utilization and the overall aesthetics of the pavilion.

[0037] The upper louver structure 4 includes a number of first blades 41, which are used to guide air circulation and prevent rainwater from entering the underground space. The first blade 41 is designed as an arc-shaped blade with the opening facing upward. This arc-shaped design helps to reduce wind resistance and effectively guides rainwater to drain along the surface of the blade. The two ends of each first blade 41 are fixedly connected to the upper louver mounting beam 42 respectively. The upper louver mounting beam 42 is located at the front and rear ends of the first blade 41 to ensure the stability of the first blade 41 and the durability of the overall structure. The upper louver mounting beam 42 is connected to the main frame 1 through the height adjustment component 7, so that the upper louver structure 4 can be adjusted in height as needed to achieve flexible air outlet opening and closing control.

[0038] The lower louver structure 5 includes a number of second blades 51, the main function of which is to further block rainwater and enhance the ventilation effect. The second blade 51 is designed to have a U-shaped cross-section. This U-shaped structure not only improves the rigidity of the blade, but also forms an effective diversion channel, allowing rainwater to flow out along the second blade 51. The two ends of the second blade 51 are respectively fixed in the U-shaped groove of the lower louver mounting beam 52. The lower louver mounting beam 52 is located at the front and rear ends of the second blade 51 to ensure the stability of the second blade 51 and the durability of the overall structure. The lower louver mounting beam 52 is also connected to the main frame 1 through a height adjustment component 7, so that the lower louver structure 5 can adjust its position at any time to meet different ventilation and rain protection needs.

[0039] The first and second blades 41, 51 are both inclined along their lengths. This design facilitates the effective guidance and drainage of rainwater. The first and second blades 41, 51 extend beyond the main frame 1 at the front air vents, forming a natural drainage channel that allows rainwater to be concentrated and drained from the outside of the main frame 1. To further optimize drainage, the first and second blades 41, 51 are designed with a slope of 2%-3%, meaning they tilt downward toward the front air vents. Specifically, the first and second blades 41, 51 are made of aluminum alloy or other rigid materials.

[0040] In this embodiment, the main frame 1 includes a bottom beam 11 fixedly mounted at the bottom of the front vent 63. This beam 11 supports and stabilizes the entire structure and provides a reliable contact surface for the louver structure. In flood control mode, the height adjustment assembly 7 controls the lower louver mounting crossbeam 52 to move downward until it contacts the bottom beam 11, effectively sealing the pavilion vent and preventing rainwater or floodwater from backflowing into the underground space, thereby significantly enhancing the flood control capabilities of the entire system.

[0041] See also Figure 4-7In some embodiments, an arc-shaped diamond mesh 43 with its opening facing downward is fixed between the first blades 41, which can effectively prevent dust and other fine particles from entering the open wind pavilion without affecting the ventilation effect. A V-shaped drainage net 44 is provided below the diamond mesh 43. The drainage net 44 is installed at the edge of the adjacent first blade 41. The design purpose is to further optimize the discharge path of rainwater. In normal state, the drainage net 44 is located above the second blade 51, and the rainwater is guided to the drainage channel of the second blade through the synergistic effect of the blade and the drainage net. When entering the flood control state, the drainage net 44 will enter the interior of the second blade 51 as the louver structure descends, ensuring that the entire system can be quickly closed in an emergency to prevent water infiltration. In order to further enhance the guiding effect of rainwater, the drainage net 44 is connected to the first blade 41 by a guide plate 45. The guide plate 45 is a bent structure. This design can accurately guide rainwater toward the second blade 51, ensuring that rainwater will not flow into the open wind pavilion vent through the ventilation area, but will be smoothly discharged through the second blade 51. The drainage net 44 uses a flexible fabric with 30% open holes, 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 effect in different states.

[0042] See also Figure 9 In one embodiment, a hanger 8 is provided at the lower side of both ends of the lower louver mounting beam 52 and at the corresponding position of the front louver 63. The hanger 8 is rotatably connected to the center position of the front louver 63. This connection method allows the front louver 63 to flexibly move and rotate under the drive of the hanger 8. The two ends of the front louver 63 are connected by a connecting rod 9 to ensure that the entire front louver 63 remains synchronized during the movement and rotation process. When the lower louver mounting beam 52 moves downward, the hanger 8 will drive the front louver 63 to move downward together. When the end of the front louver 63 close to the outside contacts the civil engineering base 3 of the open wind pavilion vent 2, the front louver 63 will flip over and enter the open wind pavilion vent 2 along with the hanger 8, which facilitates the storage of the front louver 63 in the flood prevention state.

[0043] See also Figure 10 In another embodiment, the lower sides of both ends of the lower louver mounting beam 52 are also provided with hangers 8, but at this time the hangers 8 are rotatably connected to the inner end of the front louver 63, and the center of the front louver 63 is connected through a connecting rod 9. The connecting rod 9 ensures that the entire front louver 63 remains synchronized during movement and rotation. When the lower louver mounting beam 52 moves downward, the hangers 8 also drive the front louver 63 to move downward until the outer end of the front louver 63 abuts against the civil engineering base 3 of the open wind pavilion vent 2. At this time, the front louver 63 will flip over and enter the open wind pavilion vent 2 along with the hangers 8, which facilitates the storage of the front louver 63 in the flood prevention state.

[0044] See also Figure 8 In this embodiment, the height adjustment component 7 is located in the cover 12 of the left and right air outlets of the main frame 1. This design can effectively protect the height adjustment component 7 from the influence of the external environment and ensure its stable operation. The height adjustment component 7 includes a motor 71 and a lifting rod 72. The motor 71 realizes the height adjustment of the upper louver mounting beam 42 and the lower louver mounting beam 52 by rotating the lifting rod 72. The two ends of the upper louver mounting beam 42 and the lower louver mounting beam 52 are respectively mounted on the lifting rod 72 through sliders 73. When the motor 71 drives the lifting rod 72 to rotate, the slider 73 will move up and down along the lifting rod 72, thereby driving the upper louver mounting beam 42 and the lower louver mounting beam 52 to move downward synchronously to achieve the purpose of adjusting the height. It should be noted that the height adjustment method of the height adjustment component 7 is not limited to this one. Other mechanical structures that can drive the upper louver mounting beam 42 and the lower louver mounting beam 52 to move can be applied to this embodiment.

[0045] See also Figure 11 Furthermore, the height adjustment component 7 includes a control module 74, which can switch between automatic mode and manual mode to provide flexible adjustment modes. In automatic mode, a liquid level sensor 75 is installed on the side wall of the civil engineering base 3, which can monitor the changes in the water level in real time. When the liquid level sensor 75 detects that the water level has risen, it will immediately send a signal to the control module 74. After receiving the signal, the control module 74 will automatically drive the motor 71 to operate, so that the upper louver structure 4 and the lower louver structure 5 will drop rapidly to prevent the risk of backflow caused by further rise in the water level. In manual mode, a manual control button is provided in the vehicle control room. The manual control button is electrically connected to the control module 74. When the staff believes that there is a safety hazard, they can send a signal to the control module 74 through the manual control button to manually control the motor 71 to perform the operation, ensuring that the system can be manually intervened according to actual needs. This design not only realizes the automatic control of the system, but also retains the flexibility of manual intervention, providing double protection.

[0046] To evaluate the windage efficiency of a louver structure, let's use an example. Assume the main frame 1 is 9.2m long, 3m wide, and 0.65m high. The opening distance between the first blades 41, viewed along the length of the main frame 1, is 100mm, while the total length of the first and second blades 41, 51 is 220mm. The windage efficiency at the top of the main frame 1 is 100 / 220, which is approximately 45.45%. Based on this ratio, the actual windage area is 9.2m × 3m × 45.45%, which is approximately 12.55㎡. Assuming the side louvers are designed with an 80% louver ratio, the windage area on the side is (9.2m + 3m) × 2 × 0.3m × 0.8, which is approximately 5.86㎡. Combining these two windage areas, the total windage area is 12.55㎡ + 5.86㎡, which is 18.41㎡. The area of ​​the open pavilion's air outlet is 9.2m × 3m, which is 27.6㎡. The calculated overall airflow rate of the air outlet is 27.6 m2 / 18.41 m2, which is approximately 66.7%. It should be noted that the above calculation is a simplified estimate, and the airflow rate can be adjusted according to actual needs. Theoretically, it can reach 100%. This goal can be achieved by increasing the height of the main frame 1 to expand the airflow area, thereby improving the overall airflow rate. This design flexibility allows the present invention to adapt to different ventilation needs and provide optimal air circulation.

[0047] In summary, the present invention provides a fully automatic open wind pavilion intelligent rain and flood prevention louvers, the design of which fully considers the combination of ventilation efficiency and waterproof performance. By setting up the upper and lower louver structures 4 and 5 and utilizing the staggered arrangement of their blades, full coverage of the open wind pavilion air outlet 2 is achieved, which not only ensures a high wind rate, but also effectively prevents rainwater from entering the underground space. The clever coordination of the main frame 1 and the height adjustment component 7 enables the louver structure to switch freely between daily ventilation and flood prevention states. In the flood prevention state, the upper and lower louver structures 4 and 5 can move downward to close the open wind pavilion air outlet 2, providing a reliable flood prevention barrier. In addition, by setting side louvers 6 on all sides, the ventilation effect is further improved. The design of the control module 74 integrates automatic and manual adjustment modes. Through the liquid level sensor 75 and the manual control button, intelligent automatic adjustment and manual intervention when necessary are realized to ensure the stability and safety of the system under different environmental conditions. The present invention has a reasonable structure, is easy to install, has diverse functions, and has efficient protection capabilities and broad application prospects.
