Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust window technology, and in particular to an electric smoke exhaust window for roofs. Background Technology

[0002] A rooftop electric smoke exhaust window is a ventilation and smoke extraction device installed on the roof of a building that can be opened electrically. It is mainly used for smoke extraction in fires and daily ventilation. It consists of a window sash, a drive mechanism, and a control system. It is usually linked to the fire protection system and automatically opens in the event of a fire to expel dense smoke and high-temperature gases, ensuring the evacuation of personnel and fire rescue.

[0003] However, the existing type of electric smoke exhaust window for roofs still has some drawbacks: when in use, traditional smoke exhaust windows can only be ventilated by opening and closing at an angle. When opening the smoke exhaust window for daily ventilation, the smoke exhaust window with the opening angle will have an excessive air intake, which will cause the internal air pressure to be quickly sucked out, resulting in a large negative pressure inside. Utility Model Content

[0004] The purpose of this invention is to provide an electric smoke exhaust window for rooftops, which allows for the selection of different ventilation modes based on daily use or fire smoke exhaust needs.

[0005] To achieve the above objectives, an electric smoke exhaust window for rooftops is provided, comprising: a fixed wall, a smoke exhaust pipe fixedly connected to the inner side of the fixed wall, a fixed frame fixedly connected to the inner side of the smoke exhaust pipe, a movable window rotatably connected to the inner side of the fixed frame, a groove on the upper right side of the movable window, a rotating shaft rotatably connected to the inner side of the groove, a rotating rod fixedly connected to the outer side of the rotating shaft, the front end of the rotating rod being fixedly connected to the movable window, a gear fixedly connected to the left side of the rotating shaft, a sealing cover fixedly connected to the rear end of the smoke exhaust pipe, a rack slidably connected above the sealing cover, and the front end of the rack passing through the smoke exhaust pipe and meshing with the gear;

[0007] According to the electric smoke exhaust window for roof, a smoke exhaust duct is provided inside the smoke exhaust pipe, and a limiting groove is provided at the upper end of the movable window.

[0008] According to the electric smoke exhaust window for roofs, a support plate is fixedly connected to the front end of the inner side of the smoke exhaust duct, and a smoke detector is fixedly connected to the lower end of the support plate.

[0009] According to the electric smoke exhaust window for roof, a limiting block is fixedly connected to the upper end of the limiting groove, and a lift window is slidably connected to the inner side of the limiting groove.

[0010] According to the electric smoke exhaust window for roofs, a limiting hole is provided on the inner side of the lifting window, and the limiting hole cooperates with a limiting block.

[0011] According to the electric smoke exhaust window for roof, the fixed frame has grooves at both ends on the inner side, a sliding rod is fixedly connected in the left groove, and a slider is slidably connected in the inner side of the groove, with the slider slidably connected to the upper end of the sliding rod.

[0012] According to the electric smoke exhaust window for roof, a screw is rotatably connected in the right-side groove, the slider is threadedly connected to the screw, a motor is fixedly connected to the lower end of the fixed frame, and the output end of the motor passes through the fixed frame and is fixedly connected to the screw via a coupling.

[0013] According to the electric smoke exhaust window for rooftops, a fixing rod is fixedly connected to the inner side of the slider, and the upper end of the fixing rod is fixedly connected to the lifting window.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5 This utility model provides an electric smoke exhaust window for rooftops, comprising: a fixed wall 2, a smoke exhaust pipe 1 fixedly connected to the inner side of the fixed wall 2, a fixed frame 24 fixedly connected to the inner side of the smoke exhaust pipe 1, a movable window 3 rotatably connected to the inner side of the fixed frame 24, a groove 23 on the upper right side of the movable window 3, a rotating shaft 10 rotatably connected to the inner side of the groove 23, a rotating rod 9 fixedly connected to the outer side of the rotating shaft 10, the front end of the rotating rod 9 being fixedly connected to the movable window 3, a gear 11 fixedly connected to the left side of the rotating shaft 10, a sealing cover 4 fixedly connected to the rear end of the smoke exhaust pipe 1, a rack 12 slidably connected above the sealing cover 4, the front end of the rack 12 passing through the smoke exhaust pipe 1 and meshing with the gear 11;

[0026] A cylinder 13 is fixedly connected to the rear of the upper end of the sealed cover 4. The piston rod at the front end of the cylinder 13 is connected to the rack 12. The sealed cover 4 can effectively prevent the cylinder 13 and the rack 11 from being affected by the external environment.

[0027] A smoke exhaust duct 22 is provided on the inner side of the smoke exhaust pipe 1, and a limit groove 8 is provided at the upper end of the movable window 3, so that smoke can be discharged from the upper end of the smoke exhaust pipe 1 along the inner side of the smoke exhaust duct 22.

[0028] A support plate 20 is fixedly connected to the front end of the inner side of the exhaust duct 22. A smoke detector 21 is fixedly connected to the lower end of the support plate 20. When working, the smoke detector 21 can detect the smoke and temperature inside in real time. When the smoke concentration inside is less than 20%, the smoke detector 21 will start the motor 19, thereby causing the lifting window 6 to rise to achieve the purpose of ventilation. When the smoke concentration inside is greater than 20% and the temperature is greater than 60 degrees Celsius, the cylinder 13 will be activated, thereby causing the movable window 6 to be opened.

[0029] The upper end of the limiting groove 8 is fixedly connected to the limiting block 7, and the inner side of the limiting groove 8 is slidably connected to the lifting window 6. During daily ventilation, the vertical lifting window 6 has a small opening area and adopts a vertical lifting method. During ventilation, the internal gas exchanges with the outside slowly, which can effectively prevent the internal gas from being sucked out too quickly, thereby creating negative pressure inside.

[0030] A limiting hole 5 is provided on the inner side of the lifting window 6. The limiting hole 5 cooperates with the limiting block 7. When the limiting hole 5 and the limiting block 7 are combined, the whole can form a sealed environment.

[0031] The fixed frame 24 has grooves 15 at both ends on the inner side. A slide rod 14 is fixedly connected in the left slide groove 15. A slider 16 is slidably connected in the inner side of the slide groove 15. The slider 16 is slidably connected to the upper end of the slide rod 14. When the slider 16 slides, the slide rod 14 can effectively limit its movement, so that the slider 16 always maintains horizontal movement.

[0032] A screw 18 is rotatably connected inside the right slide groove 15. The slider 16 is threadedly connected to the screw 18. A motor 19 is fixedly connected to the lower end of the fixed frame 24. The output end of the motor 19 passes through the fixed frame 24 and is fixedly connected to the screw 18 through a coupling. When the motor 19 rotates, the coupling at the front end will drive the screw 18 to rotate synchronously. Under the action of the threaded connection, the slider 16 moves synchronously.

[0033] A fixed rod 17 is fixedly connected to the inner side of the slider 16. The upper end of the fixed rod 17 is fixedly connected to the lifting window 6. When the fixed rod 17 moves, it can drive the upper lifting window 6 to move, thereby completing the opening and closing of the lifting window 6.

[0034] Working principle: During use, a support plate 20 is installed at the front end of the exhaust duct 22 inside the exhaust pipe 1, horizontally positioned with the groove 23. A smoke detector 21 is installed at the lower end of the support plate 20. The smoke detector 21 can detect the smoke concentration and temperature inside the exhaust duct 22 in real time. When the internal smoke concentration is lower than the threshold, the smoke detector 21 will start the motor 19. The rotation of the motor 19 drives the screw 18 to rotate. Under the action of the threaded connection, the slider 16 moves along the slide rod 14 in the slide groove 15, thereby driving the inner fixed rod 17 to move. The movement of the fixed rod 17 will cause the upper end to rise and fall. Window 6 is driven, causing the lifting window 6 to rise from the inside of the limiting groove 8, completing the daily ventilation and smoke extraction work. When the internal smoke concentration is higher than the threshold, cylinder 13 is activated. Under the action of cylinder 13, the front rack 12 is pulled to move. Under the meshing action, the gear 11 rotates. The rotation of gear 11 drives the inner rotating shaft 10 to rotate. The rotation of rotating shaft 10 drives the outer rotating rod 9 to rotate synchronously, thereby causing the front movable window 3 to rotate. The opening of movable window 3 maximizes the smoke extraction efficiency inside the smoke extraction window, effectively discharging the smoke inside.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
