Description

Technical Field

[0001] This utility model relates to the field of building skylight technology, and in particular to a fire-fighting ventilation skylight with a rainproof and air-guiding structure. Background Technology

[0002] Fire-fighting ventilation skylights are multifunctional devices installed on the roofs of buildings. In daily use, they provide natural ventilation, introducing fresh air and expelling stale indoor air, while also providing some natural lighting. In emergencies such as fires, they can be opened quickly through automatic or manual control to promptly expel accumulated smoke, high-temperature gases, and toxic fumes. They are widely used in industrial plants, warehouses, large public buildings, and other places that require fire-fighting smoke extraction and daily ventilation and lighting.

[0003] In normal conditions, skylights achieve natural ventilation through partial opening of the window sash or fixed ventilation openings. Utilizing the air pressure difference created by the temperature difference between indoors and outdoors, they expel stale indoor air while introducing fresh air. Their light-transmitting panels (such as glass or light-transmitting panels) allow natural light to pass through, meeting the indoor lighting needs. In the event of a fire, triggered by smoke detectors, heat detectors, or fire alarm linkage signals, the skylight is driven by a motor or push rod to open quickly (some models can open to an angle of over 90°), forming a smooth smoke exhaust channel. With the help of thermal pressure (smoke rises due to heat) and outdoor wind, dense smoke, high-temperature gases, and toxic fumes are quickly exhausted to the outside, reducing indoor smoke concentration and temperature.

[0004] In existing technologies, some fire ventilation skylights lack rain protection structures during ventilation or smoke extraction. This allows rainwater to bypass the protective structure and enter the room when the ventilation or smoke extraction window is opened, thus affecting the indoor environment. Therefore, fire ventilation skylights with rainproof and diversion structures are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fire ventilation skylight with a rainproof and air-guiding structure, which aims to improve the problem of rainwater entering the room due to the lack of a rainproof and protective structure in some existing fire ventilation skylights.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fire-fighting ventilation skylight with a rainproof and air-guiding structure includes a support frame, a support frame rotatably connected inside the support frame, a support plate fixedly connected inside the support frame, two extension plates slidably connected inside the support frame, a fixed shaft fixedly connected inside the support frame, a rotating gear rotatably connected inside the support frame, two sliding racks slidably connected inside the support frame, reset components slidably connected inside both the front and rear ends of the support frame, two fixed blocks fixedly connected to the top of each of the two extension plates, a glass plate fixedly connected inside the support frame, a fixed rod fixedly connected to the left end of the support frame, and multiple telescopic rods fixedly connected inside the fixed rod. As a further description of the above technical solution: Each of the telescopic rods is fitted with a fixing spring on its exterior. A support rod is fixedly connected inside the support frame. A sealing rod is fixedly connected to the bottom of each of the telescopic rods. A rubber rod is installed inside the support rod. A support block is fixedly connected to the top of the support plate. A connecting block is rotatably connected inside the support block. A cylinder is fixedly connected to the left end of the connecting block. A rotating block is fixedly connected to the drive end of the cylinder. A fixing plate is fixedly connected inside the support frame. A support shaft is fixedly connected inside the fixing plate. As a further description of the above technical solution: Both of the aforementioned reset components include a telescopic plate, and a reset spring is sleeved on the outside of the telescopic plate. The two telescopic plates are slidably connected to the inside of the support frame. As a further description of the above technical solution: The left ends of the two return springs are respectively fixedly connected to the inside of the two extension plates, and the right ends of the two return springs are respectively fixedly connected to the inside of the two telescopic plates. As a further description of the above technical solution: The rotating gear is internally rotatably connected to the outside of the fixed shaft, and the outside of the rotating gear is meshed with the adjacent side of the two sliding racks. As a further description of the above technical solution: The left and right ends of the two sliding racks are respectively fixedly connected to the adjacent sides of the two extension plates, and the left and right ends of the plurality of fixed blocks are respectively slidably connected to the front and rear ends of the inside of the support frame. As a further description of the above technical solution: The left and right ends of the plurality of fixed blocks are respectively in contact with the adjacent ends of the two telescopic plates, and the bottoms of the two extension plates are respectively slidably connected to the front and rear ends of the top of the support frame; As a further description of the above technical solution: The bottoms of the plurality of fixed springs are fixedly connected to the top of the sealing rod, and the bottom of the sealing rod is in contact with the top of the rubber rod.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the meshing of the rotating gear and the sliding rack drives the two extension plates to slide. The sliding of the two extension plates causes the two fixed blocks to move. Then, the reset of the two return springs causes the two telescopic plates to be embedded in the interior of the fixed blocks, fixing the fixed blocks and thus fixing the extension plates. The extension plates block and guide rainwater, thereby preventing rainwater from crossing the extension plates and entering the room, thus protecting the indoor environment.

[0008] 2. In this utility model, the rotation of the support frame drives the fixed rod to move, which in turn drives the telescopic rod and the fixed spring to move. When the sealing rod comes into contact with the rubber rod, the fixed spring is squeezed and reset to make the sealing rod tightly adhere to the top of the rubber rod, thereby improving the airtightness of the skylight, preventing rainwater from seeping in, and further enhancing the rainproof effect.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3 This utility model provides an embodiment of a fire-fighting ventilation skylight with a rainproof and air-guiding structure, including a support frame 1. The support frame 1 provides basic support for other components, thereby improving the stability of the components. A support frame 2 is rotatably connected inside the support frame 1. The support frame 1 is connected to the support frame 2 via a rotating shaft, providing support for the rotation of the support frame 2, thereby improving the rotational stability of the support frame 2. A support plate 17 is fixedly connected inside the support frame 1. The support plate 17 provides fixation for the components, and the support frame slide 1 provides support for the support plate 17, thereby improving the load-bearing capacity of the support plate 17. Two extension plates 3 are slidably connected inside the support frame 2. A sliding groove is provided inside the support frame 2 to limit the sliding of the extension plates 3 and prevent them from shifting during sliding. The bottoms of the two extension plates 3 are slidably connected to the front and rear ends of the top of the support frame 1, respectively. The support frame 1 provides support for the sliding of the extension plates 3, preventing them from deviating during sliding, thereby improving the sliding stability of the extension plates 3. A fixed shaft 4 is fixedly connected inside the support frame 2. The fixed shaft 4 provides rotational support, and the support frame 2 supports the fixed shaft 4, thereby improving the load-bearing capacity of the fixed shaft 4. A rotating gear 5 is rotatably connected inside the support frame 2. The support frame 2 has a groove inside to limit the rotation of the rotating gear 5 and prevent the rotating gear 5 from deviating during rotation. The rotating gear 5 is internally rotatably connected to the outside of the fixed shaft 4. The fixed shaft 4 provides support for the rotation of the rotating gear 5, preventing it from shaking during rotation and thus improving its vibration stability. Two sliding racks 6 are slidably connected inside the support frame 2. The left and right ends of the two sliding racks 6 are fixedly connected to adjacent sides of two extension plates 3, respectively. The sliding of the two extension plates 3 drives the two sliding racks 6 to slide inside the support frame 2. The outside of the rotating gear 5 is meshed with the adjacent sides of the two sliding racks 6. The sliding of one of the sliding racks 6 meshes with the rotating gear 5, causing the rotating gear 5 to rotate, which in turn drives the other sliding rack 6 to slide. Reset components are slidably connected inside both the front and rear ends of the support frame 2. The support frame 2 provides a reset guide for the reset components, preventing them from shifting due to excessive force. Both reset components include telescopic plates 7, which are externally slidably connected to the inside of the support frame 2. The support frame 2 provides sliding guidance for the two telescopic plates 7, preventing them from shifting during sliding. A reset spring 8 is sleeved on the outside of the telescopic plates 7, providing support for the reset spring 8, ensuring that the reset spring 8 is evenly stressed, thereby improving the service life of the reset spring 8. The left ends of the two return springs 8 are fixedly connected to the interior of the two extension plates 3, and the right ends of the two return springs 8 are fixedly connected to the interior of the two telescopic plates 7. The telescopic plates 7 slide and compress the return springs 8, causing them to deform. The extension plates 3 provide support for the return springs 8 to return to their original position, reducing the pressure on the return springs 8 and thus extending their service life. Two fixing blocks 9 are fixedly connected to the top of each of the two extension plates 3. The left and right ends of the fixing blocks 9 are slidably connected to the front and rear ends of the support frame 2. The sliding of the extension plates 3 causes the fixing blocks 9 to slide within the support frame 2. The left and right ends of the fixing blocks 9 contact the adjacent ends of the two telescopic plates 7. The sliding contact of the fixing blocks 9 with the two telescopic plates 7 causes the two telescopic plates 7 to embed into the fixing blocks 9, fixing them and preventing the extension plates 3 from moving. A glass plate 10 is fixedly connected inside the support frame 2, providing support for the glass plate 10. The glass plate 10 is used to block rainwater and prevent rainwater from entering the room. A fixed rod 11 is fixedly connected to the left end of the support frame 2 by welding, thereby improving the support stability of the fixed rod 11. Multiple telescopic rods 12 are fixedly connected inside the fixed rod 11. The telescopic rods 12 are used for telescopic movement, and the fixed rod 11 provides support for the telescopic rods 12, thereby improving the telescopic stability of the telescopic rods 12. Reference Figure 1 , Figure 4 and Figure 5Each of the multiple telescopic rods 12 is externally fitted with a fixing spring 13. The telescopic rods 12 support the fixing springs 13, ensuring even force distribution and improving their efficiency. A support rod 14 is fixedly connected internally to the support frame 1. The support rod 14 provides support for the components, and the support frame 1 secures it, increasing its load-bearing capacity. A sealing rod 15 is fixedly connected to the bottom of each of the multiple telescopic rods 12. Rotation of the support frame 2 causes displacement of the fixing rod 11, which in turn moves the sealing rod 15 via the fixed telescopic rods 12. The bottom of each of the multiple fixing springs 13 is fixedly connected to the top of the sealing rod 15. The fixing spring 13 is deformed by the pressure of the fixing rod 11, which in turn compresses the sealing rod 15. A rubber rod 16 is internally installed on the support rod 14. The support rod 14 has a groove that matches the shape of the rubber rod 16, providing airtight protection to prevent rainwater infiltration. The bottom of the sealing rod 15 contacts the top of the rubber rod 16. The rotation of the support frame 2 drives the fixed rod 11 to squeeze the telescopic rod 12 and the fixed spring 13, thereby squeezing the sealing rod 15 and making the sealing rod 15 fit tightly with the rubber rod 16. To further improve the airtightness of the sunroof and prevent rainwater infiltration, a support block 18 is fixedly connected to the top of the support plate 17 via welding. The support plate 17 provides support for the support block 18, thereby improving its stability. A connecting block 19 is rotatably connected inside the support block 18. The support block 18 is connected to the connecting block 19 via a shaft, which guides the rotation of the connecting block 19, thus improving its rotational stability. A cylinder 20 is fixedly connected to the left end of the connecting block 19, providing support and preventing the cylinder 20 from shaking during operation, thereby improving its stability. A rotating block 21 is fixedly connected to the drive end of the cylinder 20. Activating the cylinder 20 provides driving force to the rotating block 21, causing it to move. A fixing plate 22 is fixedly connected inside the support frame 2. The fixing plate 22 provides fixation for other components, and the support frame 2 provides support for the fixing plate 22, thereby improving its support stability. The fixed plate 22 is internally fixedly connected to a support shaft 23, which provides support for the rotation of the fixed plate 22, prevents the fixed plate 22 from shifting during rotation, and improves the rotational stability of the fixed plate 22.

[0013] Working principle: During ventilation, cylinder 20 is activated, causing cylinder 20 to drive rotating block 21 to move. Rotating block 21 drives support frame 2 to rotate around the pivot connected to support frame 1, thereby opening support frame 2. Simultaneously, as support frame 2 rotates, extension plate 3 is pulled to slide inside support frame 2. Pulling one extension plate 3 causes one sliding rack 6 to slide inside support frame 2. Through the meshing of one sliding rack 6 with rotating gear 5, rotating gear 5 drives another sliding rack 6 to slide, thereby driving another extension plate 3 to slide, thus unfolding extension plate 3. At the same time, the sliding of extension plate 3 causes fixed block 9 to move. Fixed block 9 presses two telescopic plates 7, causing the two telescopic plates 7 to press two return springs 8. The return of the two return springs 8 pushes the two telescopic plates 7 into fixed block 9, fixing fixed block 9 and thus fixing extension plate 3 to prevent it from moving, thereby preventing rainwater from entering the room through extension plate 3. When the sunroof is closed, the rotation of the support frame 2 drives the fixed rod 11 to move, which in turn drives the telescopic rod 12 and the fixed spring 13 to move. When the sealing rod 15 comes into contact with the rubber rod 16, the fixed spring 13 is compressed, causing it to deform. The return of the fixed spring 13 causes it to press against the sealing rod 15, thus making the sealing rod 15 fit tightly against the top of the rubber rod 16, thereby improving airtightness and preventing rainwater from seeping in.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
