Description

Technical Field

[0001] This application relates to the field of buildings, and more specifically, to a sealed, waterproof louver with flood-proof function and an underground or above-ground building on which the flood-proof louver is installed. Background Technology

[0002] In recent years, the effects of global warming have become increasingly prominent, leading to more frequent extreme weather events such as torrential rains and floods. These extreme weather events increasingly impact the normal operation of urban underground spaces and pose safety hazards to low-lying buildings above ground. In particular, when underground spaces are affected by floods, people may be trapped or injured, posing significant safety risks and hindering timely evacuation and rescue. Floods can also damage or malfunction equipment within underground spaces, affecting their normal operation. More importantly, floods can cause sewage, chemicals, and other substances to spill out of underground spaces, causing environmental pollution and irreparable damage to the surrounding ecosystem and residents' health.

[0003] In underground spaces and in the rail transit sector, most important equipment rooms are located underground. Currently, the common flood prevention method involves using ventilation louvers to provide ventilation, and then adding a flood barrier to block floodwater. This approach has three main drawbacks: First, achieving a balance between ventilation and flood barriers is difficult, especially under demanding design conditions; second, the response capability to flooding events is limited, often failing to respond promptly and lacking intelligent solutions; and third, in extreme weather, the manual installation of flood barriers in every open area of ​​the building requires significant manpower.

[0004] Currently, most venetian blinds on the market are used in residential homes. The slats are thin and fragile, and they do not have a sealing and waterproof function when closed. Some venetian blinds are equipped with smart systems, but these are often only used to control the angle of the slats to control the amount of ventilation and sunlight. In heavy rain, they cannot be remotely controlled in a timely manner to protect indoor facilities. Utility Model Content

[0005] In view of this, this application proposes a sealed, waterproof, and robust louver with flood-proof function for use in underground buildings or buildings located in low-lying areas on the ground. It can effectively prevent damage or malfunction of indoor equipment caused by extreme weather, ensure the safety of people indoors, and provide effective technical support for urban safety and sustainable development.

[0006] According to this application, a louver with flood-proof function is provided, including a column and a plurality of blades rotatably disposed on the column, and a clamping assembly rotatably disposed at at least two ends of the upper long side and the lower long side of the blades. In the closed state of the louver with flood-proof function, the ends of the upper long side and the lower long side of adjacent blades are sealed and coupled together, and the clamping assembly sealably clamps the plurality of blades, so that the louver with flood-proof function is sealed and waterproof.

[0007] Preferably, the plurality of blades are arranged in parallel, and the clamping assembly includes a clamping part and a clamping part symmetrically arranged at both ends of the upper long side and the lower long side of the blades. In the closed state of the louver with anti-flood function, the clamping part and the clamping part cooperate to apply a continuous clamping force to the plurality of blades.

[0008] Preferably, it further includes a transmission device fixedly connected to the clamping assembly, the clamping assembly being controlled to move by the transmission device, the transmission device continuously outputting power to the clamping assembly to clamp the blades when the louver with anti-flood function is closed.

[0009] Preferably, the transmission device includes a motor and a transmission mechanism rotatably connected to the output shaft of the motor; the transmission mechanism includes a plurality of transmission rods rotatably connected to each other and a fixed component and a movable component rotatably connected to the transmission rods, the fixed component being fixedly disposed on the column, and the movable component being fixedly disposed on one of the clamping parts or the clamping parts.

[0010] Preferably, the length of the clamping assembly along the column direction is equal to the sum of the external lengths of all the blades along the width direction in the closed state of the louver with anti-flood function;

[0011] The ends of the upper and lower long sides of adjacent blades are connected in a snap-fit ​​or tenon-and-mortise manner and are sealed.

[0012] Preferably, the blade is cuboid in shape and has a snap-fit ​​groove at the ends of the upper and lower long sides of the blade that are close to each other. The snap-fit ​​groove is a strip-shaped notch provided along the edges of the upper and lower long sides of the blade. A sealing element is fixedly installed in the snap-fit ​​groove. Alternatively, the blade has a tenon groove at the ends of the upper and lower long sides of the blade that are close to each other. A sealing element is fixedly installed in the tenon groove.

[0013] Preferably, the cross-sectional shape of the strip-shaped notch is square, trapezoidal, circular arc, or triangular.

[0014] Preferably, the sealing element is a rubber or silicone sealing strip that satisfies water tightness, and the blade and the clamping assembly are made of a high-strength, waterproof material.

[0015] Furthermore, the louver with flood prevention function provided in this application also includes an intelligent control device. The intelligent control device includes a water level monitoring device and a main control device disposed outside the louver with flood prevention function. The main control device is electrically connected to the motor of the transmission device. The main control device can remotely control the operation of the motor to close the louver with flood prevention function and continuously output power to the clamping assembly.

[0016] According to another aspect of this application, a building is also provided, including a door, a window, and a wall, wherein the window is a louvered window with flood protection function provided in this application.

[0017] According to the technical solution of this application, the main purpose of designing a flood-resistant louver with ventilation function is to solve the problem that underground or above-ground facilities and equipment rooms are easily affected by flooding during floods and other water disasters, thereby improving the safety and stability of underground or above-ground facilities. Specifically, the flood-resistant louver provided in this application has the following beneficial effects:

[0018] 1. Enhanced safety: By preventing water from entering equipment rooms, these flood-proof louvers, which also provide ventilation, help reduce the impact of flooding on underground facilities and improve the overall safety and stability of underground spaces.

[0019] 2. Enhanced rapid response capability: The flood-proof louvers, which combine flood prevention and ventilation, are equipped with intelligent sensor control or water level alarm devices. They can provide information to the central control unit in a timely manner when the water level rises, and the control room management personnel can realize batch automatic closure. The flood-proof louvers can quickly block water flow in the event of floods, improving the timely response capability of underground facilities.

[0020] 3. Reduced Labor Costs: Buildings with traditional ventilation louvers typically also have flood barriers. In extreme weather conditions, these barriers need to be manually installed at every opening area within a certain timeframe, requiring significant manpower. This invention enables rapid response to flood-resistant louver closing requests and batch control of flood-resistant louvers, greatly improving management efficiency and reducing labor costs.

[0021] 4. High compatibility: Compared with traditional flood prevention facilities, louvers with flood prevention function have lower requirements for civil engineering coordination, are more flexible in construction, and are not limited by the scene.

[0022] 5. High reliability: The louvers with flood protection function can be closed not only by remote control of the motor drive, but also by manual means, which is more reliable than traditional facilities.

[0023] 6. Modular installation: The louvers with flood protection function can be customized according to project requirements and installed in a modular manner.

[0024] On the other hand, this utility model also provides a building equipped with the flood-proof louvers provided in this application. Clearly, this type of building has a greater function in flood prevention and disaster relief. In the event of torrential rain and floods, in the field of rail transit, this type of building can block rainwater from entering the building, effectively protecting important equipment inside. Such buildings, located in low-lying areas, can reduce the amount of water entering the building or slow down the time it takes for floodwater to enter, thereby ensuring the safety of people and property inside the building and buying valuable time for rescue.

[0040] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in specific embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0041] It should be noted that the terms "upper," "lower," "left," and "right" used in this utility model are merely descriptive terms and should not be considered as limitations on this utility model application.

[0042] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the flood-proof louver in the first embodiment of this application includes a column 10 and a plurality of blades 20 rotatably disposed on the column 10. It also includes a clamping assembly 30 rotatably disposed at at least two ends of the upper long side 21 and the lower long side 22 of the blades 20. Preferably, the plurality of blades 20 are arranged in parallel. The clamping assembly 30 includes a clamping part 31 and a clamping part 32 symmetrically disposed at both ends of the upper long side 21 and the lower long side 22 of the blades 20. In the closed state of the flood-proof louver, the ends of the upper long side 21 and the lower long side 22 of the adjacent blades 20 are sealed and coupled together. The clamping assembly 30 sealably clamps the plurality of blades 20 and the clamping part 31 and the clamping part 32 cooperate to apply a continuous clamping force to the plurality of blades 20. When the flood-proof louver is closed, the clamping part 31 and the clamping part 32 continuously output power to the multiple blades 20 of the flood-proof louver, causing the clamping part 31 and the clamping part 32 to combine together to form a sealing clamping structure covering the planar window body composed of multiple blades 20, effectively preventing water from entering the building from the vertical sides of the flood-proof louver window body; and the continuously output power extends through the multiple blades 20 to the ends of the upper long side 21 and the lower long side 22 of the blades that are close to each other, making the end seal have a stronger pressure resistance effect, thereby making the flood-proof louver sealed and waterproof.

[0044] from Figure 1 and Figure 2 As can be seen from the description, the flood-resistant louver in the first embodiment of this application also includes a transmission device 40 fixedly connected to the clamping assembly 30. The two sets of clamping assemblies 30 are controlled to move by the transmission device 40. When the flood-resistant louver is closed, the transmission device 40 continuously outputs power to the two sets of clamping assemblies 30 to clamp the blades 20. The continuous power output is provided by the motor 41 of the transmission device 40, and the motor output shaft 411 is rotatably connected to the transmission mechanism 42. The transmission mechanism 42 includes multiple rotatably interconnected transmission rods 421 and fixed assemblies 422 and moving assemblies 423 rotatably connected to the transmission rods 421. Figure 1 As can be seen, two sets of four fixed components 422 are fixedly installed on the two columns 10, and two sets of six moving components 423 are fixedly installed on the two clamping parts 31.

[0045] During use, when the flood-proof louvers are closed, the motor 41 performs two actions to achieve waterproof sealing. The first action is that the output shaft 411 of the motor 41 rotates, driving the long transmission rod 421 from... Figure 2The device moves upwards from the indicated position. The fixing component 422 is screwed onto the column 10, serving as the rotational support point for the rotating arm connected to the fixing component 422. The long transmission rod 421 drives the rotating arm to rotate, and the rotating arm drives the short transmission rod 421 connected to the moving component 423 to move upwards. This transmits power to the clamping component 30 and multiple blades 20, and through the motor 41, provides continuous power to press the sealing coupling of the blades 20, forming a frontal waterproof seal. Figure 7 As can be seen, after the blades 20 are closed, when viewed from the side, multiple blades 20 will form a complete linear side. At this time, the two sets of clamping components 30 on both sides of the column 10 continuously squeeze the sides of multiple blades 20 to solve the sealing problem of the vertical side of the louver with anti-flood function, so that the entire window has an overall waterproof sealing effect.

[0046] Furthermore, the length of the clamping assembly 30 along the column 10 is equal to the sum of the external lengths of all the blades 20 in the width direction when the louver with flood protection function is closed; thus, the column 10 and all the blades 20 form a complete cuboid when the louver with flood protection function is closed, and there will be no gaps between the column 10 and the blades 20 and the edge of the window frame, which further improves the waterproof and airtightness of the louver with flood protection function when closed.

[0047] Specifically, from Figure 3 and Figure 6 As can be seen, the blades 20 are rectangular in shape, and the long sides 21 and the lower long sides 22 of the blades are provided with locking grooves 50. In the first embodiment of the blade locking grooves, the locking grooves are square. When the louver with flood prevention function is closed, the square locking grooves 51 provided at the two ends of the long sides 21 and the lower long sides 22 of the blades are interlocked to form a zigzag interlocking structure. The interlocking is tight and there are no gaps. When water seeps in from the outside through the zigzag interlocking structure of the louver with flood prevention function, the water needs to move upward from the bottom along the zigzag interlocking structure. It needs to overcome its own gravity, which is a process of water level rise. Therefore, the blades 20 with this structure can effectively prevent water from seeping in by sealing each other.

[0048] Figure 9 In a second embodiment of the blade locking groove 50 of this application, the locking groove 50 is a trapezoidal locking groove 52. The inclined mating surfaces make it easier for the two blades 20 to engage when closed.

[0049] Figure 10 The third embodiment of the blade snap-fit ​​groove 50 of this application is an arc-shaped snap-fit ​​groove 53. The arc-shaped mating surface allows the sealing strip to fit more firmly against the mating surface, further improving the firmness of the seal 70.

[0050] Figure 11 The fourth embodiment of the blade snap-fit ​​groove of this application is a triangular snap-fit ​​groove 54.

[0051] from Figure 12 As can be seen, in the first embodiment of the blade tenon and mortise joint in this application, the ends of adjacent blades 20 that are close to each other are connected in a tenon and mortise joint and sealed.

[0052] from Figure 4 As can be seen from this, the sealing element 70 can be fixedly installed in the snap-fit ​​groove 50 and the tenon groove 60.

[0053] Preferably, the seal 70 is a rubber or silicone seal that satisfies water tightness, and the blade 20 and clamping assembly 30 are made of a high-strength, waterproof material.

[0054] The slats 20 of the flood-resistant louvers are designed with snap-fit ​​or tenon-and-mortise joints, and are equipped with rubber or silicone sealing strips to ensure high water tightness when closed. When designing flood-resistant louvers, calculations must be performed on water pressure and the cross-section of the louver components in the closed state to ensure that the louvers can withstand the impact of floodwaters and maintain good sealing performance. At the same time, the cross-sectional dimensions of the slats 20 should also be limited to ensure the structural stability and service life of the flood-resistant louvers. Flood-resistant louvers can be manufactured using waterproof aluminum alloy materials, combined with a waterproof sealing design to prevent water seepage into the building. The slat material 20 should be selected based on its water resistance and strength; waterproof plastics or stainless steel can be used to ensure that it will not fail due to moisture during flooding.

[0055] Furthermore, such as Figure 1 As shown, the first embodiment of the louver with flood prevention function provided in this application also includes an intelligent control device 80. The intelligent control device 80 includes a water level monitoring device 81 and a main control device 82 disposed outside the louver with flood prevention function. The main control device 82 is electrically connected to the motor 41 of the transmission device 40. The main control device 82 can remotely control the operation of the motor 41 to close the louver with flood prevention function.

[0056] A water level monitoring device 81 or a sensing device is installed on the exterior of the flood-resistant louvers. The main control device 82 uses a combination of manual, mechanical, and electric valves for linkage control. The water level monitoring device 81 installed on the exterior of the flood-resistant louvers is electrically connected to the building's overall equipment system. When the water level around the louvers rises to a certain level, the water level monitoring device 81 sends the water level information to the main control device 82 and automatically triggers an alarm. The management personnel at the main control device 82 then assess the situation and take appropriate actions. Management personnel can remotely control the motor 41 to precisely and batch close the flood-resistant louvers in the affected area, while the flood-resistant louvers in other safe areas can operate normally. Under extreme conditions, the flood-resistant louvers can also be closed manually to prevent water from entering the building's interior space.

[0057] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0058] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this utility model.
