Description

Technical Field

[0001] This utility model belongs to the field of factory ventilation technology, specifically, it relates to a ventilation and rainproof louver. Background Technology

[0002] The container production line workshop generates heat from machinery, electrical rooms, welding, and dust, necessitating good ventilation. Therefore, ventilation systems are installed on the roof. High-level ventilation windows often use traditional PVC windows, aluminum alloy tilt-and-turn windows, or traditional louvers. Traditional louvers offer limited ventilation and are susceptible to rainwater intrusion during strong winds and rain. Ordinary sliding windows require manual operation for opening and closing, posing challenges for large workshops. Aluminum alloy tilt-and-turn windows are expensive and offer only average ventilation and rain protection. Due to the high roof height, opening and closing these windows is inconvenient. While ventilation is necessary in summer, timely closure during storms can lead to significant rainwater leakage and potential safety hazards.

[0003] Therefore, developing a ventilated and rainproof louver that can ensure ventilation while preventing rainwater from entering the room during rainy weather, and that can automatically open after the rainwater evaporates, is an urgent technical problem to be solved. Summary of the Invention

[0026] In some embodiments of this application, the lower wall of the rectangular through cavity is formed with an inclined portion, and the height of the inclined portion gradually decreases from the direction near the building window to the direction away from the building window;

[0039] Compared with the prior art, the advantages and positive effects of this utility model are:

[0040] By installing ventilated and rainproof louvers at building windows, each comprising an inlet section, a first rotating section, a first guide section, a second rotating section, and a second guide section, in the first state, the wind speed is low, and the wind force cannot drive the first and second rotating sections to rotate. Multiple first airflow channels are formed through the inlet section, the first rotating section, the first guide section, the second rotating section, and the second guide section, and these multiple first airflow channels extend to the building windows. These multiple first airflow channels are interconnected, allowing air to flow through them, thereby achieving airflow and gas exchange between the building's interior and exterior air. In the second state, rainwater drives the first or second rotating section to rotate, and the rainwater flows downwards along the first and second rotating sections, thus preventing rainwater from entering the building windows. The second state also creates a second airflow channel, thus enabling indoor and outdoor ventilation even under rainproof conditions.

[0041] In the third state, the wind speed is relatively high, and the air can drive the first and second rotating parts to rotate, forming a third airflow path. Since the fluctuations formed in the third airflow path are more than those in the first airflow path, the wind speed is reduced. The airflow after the wind speed is reduced can pass through the third airflow path. In strong wind weather, it can also play a normal ventilation role by slowing down the airflow.

[0042] This allows for ventilation of both indoor and outdoor spaces while preventing rainwater from entering the building and reducing wind speed during strong winds. Furthermore, the entire process can be automated, eliminating the need for personnel to climb to open or close windows and reducing safety risks for operators.

[0084] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0085] In some embodiments of this application, a ventilated and rainproof louver is disclosed, such as... Figure 2 , Figure 3 As shown, indoor and outdoor air can be ventilated and exchanged through the ventilated and rainproof louvers. Figure 4 , Figure 5 As shown, in rainy weather, the louvers prevent rainwater from entering the building and prevent rainwater from entering the building window 100 through the ventilated and rainproof louvers. Under these conditions, indoor and outdoor air can still be ventilated through the windproof and rainproof louvers. In windy weather, the ventilated and rainproof louvers can slow down the wind speed and ensure normal indoor and outdoor ventilation.

[0086] The first state is defined as the state under normal wind speed conditions, where the wind speed cannot drive the first rotating part 300 and the second rotating part 500 to rotate. The second state is defined as the state under rain conditions, where the rainwater can drive the first rotating part 300 or the second rotating part 500 to rotate. The third state is defined as the state under strong wind conditions, where the wind speed can drive the first rotating part 300 or the second rotating part 500 to rotate.

[0087] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the ventilation and rainproof louver includes an inlet 200, a first rotating part 300, a first guide part 400, a second rotating part 500, and a second guide part 600.

[0088] An inlet portion 200, a first rotating portion 300, a first guide portion 400, a second rotating portion 500, and a second guide portion 600 are arranged sequentially from the direction away from the building window 100 to the direction closer to the building window 100. Multiple airflow passages are formed through the inlet portion 200, the first rotating portion 300, the first guide portion 400, the second rotating portion 500, and the second guide portion 600.

[0089] In the first state, its airflow path is defined as the first airflow path 710.

[0090] In the second state, its airflow path is defined as the second airflow path 720.

[0091] In the third state, its airflow path is defined as the third airflow path.

[0092] Multiple airflow channels extend to 100 windows of the building.

[0093] Specifically, multiple airflow paths are set up in parallel.

[0094] In the first state, such as Figure 2 , Figure 3 As shown, airflow can pass through the first airflow passage 710.

[0095] In the second state, such as Figure 4 , Figure 5 As shown, rainwater enters the airflow passage and drives the first rotating part 300 or the second rotating part 500 to rotate, or the first rotating part 300 and the second rotating part 500 rotate simultaneously, to block rainwater from entering the airflow passage located behind the first rotating part 300. In this state, airflow can still pass through the second airflow passage 720.

[0096] If the rainwater fails to drive the first rotating part 300 to rotate, for example, if the first rotating part 300 becomes stuck and fails to rotate, the rotation of the first rotating part 300 will not completely block the rainwater, and the rainwater can pass through the first rotating part 300 and enter the subsequent area of ​​the second airflow passage 720.

[0097] When rainwater enters the second rotating part 500, the rainwater drives the second rotating part 500 to rotate, and the rotated second rotating part 500 is used to block the rainwater from entering the second airflow passage 720.

[0098] In the third state, strong winds can drive the first rotating part 300 or the second rotating part 500 to rotate. Through the rotation of the first rotating part 300 or the second rotating part 500, the fluctuation of the extension trajectory of the third airflow passage can be increased, thereby reducing the speed of airflow and reducing the strong winds entering the third airflow passage to weak winds.

[0099] In some embodiments of this application, the inlet portion 200 includes a plurality of inlet blades 210. The plurality of inlet blades 210 extend horizontally. The plurality of inlet blades 210 are spaced apart vertically.

[0100] In order to guide the airflow, the guide vanes 210 are inclined upward in the direction from near the building window 100 to away from the building window 100.

[0101] The first rotating part 300 includes a plurality of first rotating blades 310. The plurality of first rotating blades 310 extend horizontally. The plurality of first rotating blades 310 are spaced apart vertically.

[0102] In order to achieve the effect of rainwater, such as Figure 4 , Figure 5 As shown, the first rotating part 300 rotates, and the first rotating blade 310 can rotate around its central part. Rainwater can drive the first rotating blade 310 to rotate around its central part until the first rotating blade 310 tilts upward from the direction near the building window 100 to the direction away from the building window 100, thereby forming a large angle between the first rotating blade 310 and the guide blade 210. Rainwater cannot pass through the guide blade 210 and then through the first rotating blade 310. Rainwater flows directly through the first rainwater passage 810 formed between the guide blade 210 and the first rotating blade 310, and can flow downward through the first rainwater passage 810.

[0103] The first guide section 400 includes a plurality of first guide blades 410. The plurality of first guide blades 410 extend horizontally. The plurality of first guide blades 410 are spaced apart vertically.

[0104] The second rotating part 500 includes a plurality of second rotating blades 510. All of the plurality of second rotating blades 510 extend horizontally. The plurality of second rotating blades 510 are spaced apart vertically.

[0105] In order to achieve the effect of rainwater, such as Figure 4 , Figure 5As shown, the second rotating part 500 rotates, and the second rotating blade 510 can rotate around its central part. Rainwater can drive the second rotating blade 510 to rotate around its central part until the second rotating blade 510 tilts downwards from the direction near the building window 100 to the direction away from the building window 100, thereby forming a large angle between the second rotating blade 510 and the first rotating blade 410. Rainwater cannot pass through the first rotating blade 410 and then through the second guide blade 610. Rainwater flows directly through the second rainwater passage 820 formed between the second rotating blade 510 and the first guide blade 410, and can flow downwards through the second rainwater passage 820.

[0106] In the third state, under the action of strong wind, the first rotating part 300 increases the fluctuation of the third airflow passage by rotating, which reduces the wind speed of the strong airflow flowing through the third airflow passage.

[0107] In the third state, under the action of strong wind, the second rotating part 500 increases the fluctuation of the third airflow passage by rotating, which reduces the wind speed of the strong airflow flowing through the third airflow passage.

[0108] The second guide section 600 includes a plurality of second guide blades 610. The plurality of second guide blades 610 extend horizontally. The plurality of second guide blades 610 are spaced apart vertically.

[0109] An airflow passage is formed between two adjacent inlet blades 210, two adjacent first rotating blades 310, two adjacent first guide blades 410, two adjacent second rotating blades 510, and two adjacent second guide blades 610.

[0110] Specifically, the first rotating blade 310 includes a first bent portion 311 and a first stop portion 312. The first bent portion 311 protrudes upward. The first bent portion 311 is rotatable about a bend formed thereon. The first bent portion 311 includes a first end 3111 and a second end 3112. The first end 3111 and the second end 3112 are connected through the bend.

[0111] The first end 3111 of the first bend is formed on the side of the first bend 311 near the building window 100.

[0112] The second end 3112 of the first bend is formed on the side of the first bend 311 away from the building window 100.

[0113] The weight of the first end 3111 of the first bend is greater than the weight of the second end 3112 of the first bend. Under the action of gravity, the first end 3111 of the first bend can drive the first bend 311 to rotate around the bend until it abuts against the first stop 312.

[0114] The height of the first stop portion 312 is similar to the height of the adjacent first guide portion 400. This ensures that, in the first state, the first rotating portion 300 and the first guide portion 400 are at similar heights and are arranged adjacent to each other. This allows airflow to pass through more smoothly.

[0115] The first stop 312 is used to limit the extreme position of the rotation of the first bending part 311. When it is in the extreme position that abuts against the first stop 312, the airflow passage is open.

[0116] Specifically, the second rotating blade 510 includes a second bent portion 511 and a second stop portion 512. The second bent portion 511 is provided to protrude upward. The second bent portion 511 is rotatable about the bend formed thereon. The second bent portion 511 includes a first end 5111 and a second end 5112. The first end 5111 and the second end 5112 of the second bent portion are connected through the bend.

[0117] The first end 5111 of the second bend is formed on the side of the second bend 511 near the building window 100.

[0118] The second end 5112 of the second bend is formed on the side of the second bend 511 away from the building window 100.

[0119] The weight of the first end 5111 of the second bend is greater than the weight of the second end 5112 of the second bend. Under the action of gravity, the first end 5111 of the second bend can drive the second bend 511 to rotate around the bend until it abuts against the second stop 512.

[0120] The height of the second stop portion 512 is similar to the height of the adjacent first guide portion 400. This ensures that, in the first state, the second rotating portion 500 and the second guide portion 600 are at similar heights and are arranged adjacent to each other. This allows airflow to pass through more smoothly.

[0121] The second stop 512 is used to limit the extreme position of the rotation of the second bend 511. When the second stop 512 is in the extreme position, the airflow passage is open.

[0122] The first guide section 400 and the second guide section 600 are mainly used to guide the airflow through the airflow passage.

[0123] The first guide vane 410 and the second guide vane 610 can also guide rainwater.

[0124] Specifically, the first guide vane 410 can be a bent vane with an upward convex center. The second guide vane 610 can be a bent vane with an upward convex center.

[0125] The protrusions formed on the first guide vane 410 and the protrusions formed on the second guide vane 610 can both play a certain role in blocking rain.

[0126] The first guide vane 410 and the second guide vane 610 are fixedly installed.

[0127] In some embodiments of this application, during the rotation of the first bending portion 311 and the second bending portion 511 under the action of wind and rain, rainwater hits the second end 3112 of the first bending portion and the second end 5112 of the second bending portion, thereby driving the first bending portion 311 and the second bending portion 511 to rotate until the first end 3111 of the first bending portion abuts against the first stop portion 312 located above it, and the first end 5111 of the second bending portion rotates to abut against the second stop portion 512 located above it, thereby limiting the rotation limit position of the first bending portion 311 and the second bending portion 511 in the second state.

[0128] In the second state, a first rainwater passage 810 is formed between the inlet 200 and the first rotating part 300. A second rainwater passage 820 is formed between the first guide 400 and the second rotating part 500. Rainwater can flow downwards through the first rainwater passage 810, or rainwater can flow downwards through the second rainwater passage 820. This achieves rainwater drainage. Because multiple second airflow passages 720 are still formed while providing rain protection, ventilation performance can still be guaranteed even while providing rain protection.

[0129] After the rainwater disappears due to evaporation and other factors, the first end 3111 of the first bend and the first end 5111 of the second bend rotate under the action of gravity until the first end 3111 of the first bend abuts against the adjacent first stop 312 and the first end 5111 of the second bend abuts against the adjacent second stop 512, thereby restoring the airflow passage to the first state, and the airflow passes through the first airflow passage 710 to achieve the ventilation function of the ventilation and rainproof louver.

[0130] In some embodiments of this application, during the rotation of the first bend 311 and the second bend 511 under strong wind, the strong wind acts on the second ends 3112 of the first bend and 5112 of the second bend, thereby driving the first bend 311 and the second bend 511 to rotate until the first end 3111 of the first bend abuts against the first stop 312 located above it, and the first end 5111 of the second bend rotates to abut against the second stop 512 located above it, thereby limiting the rotation limit positions of the first bend 311 and the second bend 511 in the third state. Due to the above-mentioned rotation action, the fluctuations in the third airflow passage are greater than the fluctuations in the first airflow passage 710, thereby achieving the effect of reducing wind speed.

[0131] In some embodiments of this application, the ventilation and rainproof louver also includes a window frame body 900, in which a rectangular through cavity 910 is formed. The inlet portion 200, the first rotating portion 300, the first guide portion 400, the second rotating portion 500, and the second guide portion 600 are all arranged horizontally within the rectangular through cavity 910.

[0132] The two ends of the inlet 200 are fixedly mounted on the inner wall of the rectangular through cavity 910.
