Description

Technical Field

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

[0002] In underground engineering design, in order to minimize the impact on the urban landscape, open low-wind pavilions are usually the preferred ventilation design solution. The main advantage of this design is that it is relatively low in height, usually designed to be 1 to 1.2 meters above the ground, and can be well integrated with the surrounding landscape, thus having less impact on the urban environment. However, although the open low-wind pavilion excels in aesthetics and landscape coordination, its design also brings some significant disadvantages, especially in terms of rain and flood prevention.

[0003] The existing open low wind pavilion design has many serious defects due to its openness. First, on rainy days, rainwater will enter the underground space without hindrance, forcing the project party to set up water collection wells, 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, bringing potential safety hazards. Especially in extreme weather conditions, due to the low height of the wind pavilion from the ground, rainwater may flow back into the underground space, causing serious safety risks. Although the prior art also uses upper and lower blinds to block rainwater from entering through the structure of the blinds, 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 view of the shortcomings of the prior art, the present invention proposes a fully automatic open wind pavilion intelligent rain and flood prevention shutters. Through the design of the shutters, not only the wind rate is significantly improved, ensuring that the ventilation effect meets the standard requirements, but also the main frame design 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, which greatly simplifies the installation process, reduces engineering costs and improves the safety and reliability of the system.

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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention 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 to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate 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, realizations 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 open wind pavilion intelligent rain and flood prevention shutter, including a main frame 1 and a shutter structure. The main frame 1 is arranged on the upper part of the civil engineering base 3 of the open wind pavilion vent 2. The main frame 1 is an integral structure, which can stably support the entire shutter structure, and can be directly placed at the existing open wind pavilion vent 2 without destroying the civil engineering structure during installation. The shutter structure includes an upper shutter structure 4, a lower shutter structure 5 and side shutters 6. The shutter structure is installed on the main frame 1. The blades of the upper shutter structure 4 and the lower shutter structure 5 are staggered, so that the vertical projection of the blades of the upper shutter structure 4 and the lower shutter structure 5 can completely cover the open wind pavilion vent 2, effectively blocking 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 distance 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 passing requirements of the open wind pavilion. At the same time, the design can also guide rainwater along the length direction of the blades and drain from the front side vents, thereby effectively draining rainwater while maintaining good ventilation effects. 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 vent 2 to prevent ground water from backflowing.

[0036] The side louvers 6 are arranged around the main frame 1, namely the left air outlet, the right air outlet, the front air outlet and the rear air outlet, which are the left louver 61, the right louver 62, the front louver 63 and the rear louver 64 respectively. The left louver 61, the right louver 62 and the rear louver 64 are fixed on the main frame 1 to ensure the air circulation of the left air outlet, the right air outlet and the rear air outlet, and improve the overall air flow rate. The front louver 63 is located at the lower part of the lower louver structure 5, and can be stored in the open air pavilion air outlet 2 as the lower louver structure 5 moves downward, without affecting the movement of the upper louver structure 4 and the lower louver structure 5, further optimizing the space utilization and the overall aesthetics of the wind pavilion.

[0037] The upper louver structure 4 includes a plurality 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 guide rainwater to be discharged along the surface of the blade. The two ends of each first blade 41 are respectively fixedly connected to the upper louver mounting beam 42, which 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 plurality of second blades 51, the main function of which is to further block rainwater and enhance ventilation. The second blade 51 is designed as a blade with 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 the height adjustment component 7, so that the lower louver structure 5 can be adjusted at any time to meet different ventilation and rain protection requirements.

[0039] The first blade 41 and the second blade 51 are both inclined in the length direction, which is helpful for the effective guidance and discharge of rainwater. The first blade 41 and the second blade 51 extend out of the main frame 1 at the position of the front air outlet 63, forming a natural drainage channel, so that rainwater can be discharged from the outside of the main frame 1. In order to further optimize the drainage effect, the slope of the first blade 41 and the second blade 51 is designed to be 2%-3%, that is, they are inclined downward toward the front air outlet 63. Specifically, the material of the first blade 41 and the second blade 51 is aluminum alloy or other rigid materials.

[0040] In this embodiment, the main frame 1 includes a bottom beam 11 fixedly arranged at the bottom of the front air outlet 63, which supports and stabilizes the entire structure and provides a reliable contact surface for the shutter structure. In the flood prevention state, the height adjustment component 7 controls the lower shutter installation beam 52 to move downward until the lower shutter installation beam 52 contacts the bottom beam 11, effectively closing the wind pavilion air outlet and preventing rainwater or flood water from flowing back into the underground space, thereby greatly improving the flood prevention capacity of the entire system.

[0041] See also Figure 4-7In some embodiments, an arc-shaped diamond mesh 43 with the opening facing downward is fixedly provided 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, and the drainage net 44 is installed at the edge of the adjacent first blade 41, and the design purpose is to further optimize the discharge path of rainwater. In the daily 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 61 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 bending structure. This design can accurately guide rainwater in the direction of 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 adopts a flexible fabric with 30% openings, which can ensure its flexibility and adaptability when guiding rainwater and storing it, without affecting the overall shutter structure, and give full play to its protective effect in different states.

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

[0043] See also Fig.10 In another embodiment, the lower sides of both ends of the lower louver mounting beam 52 are also provided with suspension rods 8, but at this time the suspension rods 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 suspension rods 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 suspension rods 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 a slider 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 Fig.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 change of water level in real time. When the liquid level sensor 75 detects that the water level rises, 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 water level. In manual mode, a manual control button is provided in the vehicle control room, and 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, and 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] In order to evaluate the windage rate of the louver structure, an example is used to illustrate. Assuming that the size of the main frame 1 is 9.2m long, 3m wide, and 0.65m high, from the length direction of the main frame 1, the opening distance between the first louver 41 is 100mm, and the overall length of the first louver 41 and the second louver 51 is 220mm. The windage rate of the top of the main frame 1 = 100 / 220≈45.45%. Based on this ratio, the actual windage area = 9.2m×3m×45.45%≈12.55㎡. Assuming that the side louvers are designed according to the louver ratio of 80%, the windage area of ​​the side = (9.2m+3m)×2×0.3m×0.8≈5.86㎡. Combining the windage areas of these two parts, the total windage area = 12.55㎡+5.86㎡=18.41㎡. The area of ​​the open wind pavilion vent = 9.2m×3m=27.6㎡. The calculated overall airflow rate of the air outlet is 27.6㎡ / 18.41㎡≈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. The flexibility of this design enables the present invention to adapt to different ventilation needs and provide the best air circulation effect.

[0047] In summary, the present invention provides a fully automatic open wind pavilion intelligent rain and flood prevention shutter, the design of which fully considers the combination of ventilation efficiency and waterproof performance. By setting the upper and lower shutter structures 4, 5, and utilizing the staggered arrangement of their blades, the full coverage of the open wind pavilion vent 2 is achieved, which not only ensures a high wind rate, but also effectively prevents rainwater from entering the underground space. The ingenious cooperation between the main frame 1 and the height adjustment component 7 enables the shutter structure to switch freely between daily ventilation and flood prevention states. In the flood prevention state, the upper and lower shutter structures 4, 5 can move downward to close the open wind pavilion vent 2, providing a reliable flood prevention barrier. In addition, by setting side shutters 6 around, 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.
