Description

Technical Field

[0001] This invention relates to the field of basement skylight technology, and more particularly to a basement smoke exhaust skylight that can improve lighting effects. Background Technology

[0002] In existing buildings, many structures include basements to improve land resource utilization. Basements typically suffer from low ventilation efficiency and dim lighting. Skylights installed on the sloping roofs of basements, with mechanical smoke extraction devices such as smoke exhaust fans fixed inside, are used to expel smoke and dust. By directing the exhaust fans outwards, air convection is created near the skylight opening, accelerating the removal of smoke and dust. However, when smoke and dust are not needed, the smoke extraction devices still obstruct the skylight when it is closed, affecting lighting in the basement and making it colder and damper. Reduced sunlight exposure for people in the basement is also detrimental to prolonged indoor activities. Therefore, designing a basement smoke extraction skylight that minimizes the obstruction of windows by smoke extraction devices and improves lighting when windows are closed has become an urgent technical problem to be solved. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a basement smoke exhaust skylight that can improve lighting performance.

[0004] The present invention provides a basement smoke exhaust skylight that improves lighting performance. The skylight includes a mounting bracket and a window frame. A slide rail and a gear shaft are connected to the mounting bracket. The slide rail is located on the indoor-facing side of the mounting bracket and is arc-shaped with one end extending to the side of the mounting bracket. A movable seat is slidably connected to the slide rail. The gear shaft is positioned corresponding to the center of the slide rail and is a driven gear. The movable seat is equipped with a smoke exhaust fan and a linkage rod, one end of which is connected to the gear shaft. The window frame is housed within the mounting bracket and has a hinge shaft that is axled to the mounting bracket. A drive gear is coaxially connected to the hinge shaft. The drive gear and the driven gear are meshing bevel gears.

[0005] With the above structure, a drive gear is connected to the hinge shaft of the window frame, and a driven gear is connected to the gear shaft. The drive gear and the driven gear are meshing bevel gears. When the window frame is opened from the mounting bracket, the window frame drives the hinge shaft to rotate. The drive gear rotates coaxially with the hinge shaft, driving the meshing driven gear to rotate. The driven gear drives the connected gear shaft to rotate. One end of the linkage rod is connected to the gear shaft to move in a circular trajectory. The position of the gear shaft corresponds to the center of the slide rail. As the linkage rod moves, it pushes the moving seat to move along the arc-shaped slide rail. The smoke exhaust fan moves with the slide rail to the bottom of the mounting bracket and aligns with the opened window frame. The smoke exhaust fan is then activated to blow air outwards from the skylight, accelerating the discharge of smoke and dust from the basement to the outside. During the closing of the window frame, the hinge shaft, drive gear, driven gear, and gear shaft rotate in opposite directions, causing the moving seat to slide onto the slide rail and extend to one end of the mounting bracket. The exhaust fan moves to the side and is offset from the window frame, preventing the exhaust fan from blocking the window frame when the window is not open for smoke extraction. This improves the lighting effect in the basement after the skylight is closed, helping people to receive sufficient sunlight when spending long periods of time in the basement. The skylight is opened and closed via a rotating shaft and gear transmission. When opened, the exhaust fan moves to the bottom of the window frame to accelerate the extraction of indoor smoke and dust. When closed, the exhaust fan moves to the side of the mounting bracket and is offset from the window frame, ensuring sufficient space under the window frame for sunlight to enter the basement and improving the cold and damp indoor environment.

[0006] As a further improvement of this utility model, a rotatable support rod is axially connected to one side of the window frame, and a slot is provided on the other side of the mounting bracket corresponding to the hinge axis. The slot's opening direction, position, and size are all matched with the support rod.

[0007] With the above structure, after opening the window frame, the support rod is rotated to a position perpendicular to the hinge axis. The end of the support rod away from the window frame is aligned downwards and inserted into the slot, so that the mounting bracket, window frame, and support rod form a stable triangular support structure, keeping the window frame in the open state and preventing accidental contact or closure of the window frame due to its own weight.

[0008] As a further improvement of this utility model, the end of the support rod is provided with an arc-shaped guide surface, and the connecting shaft between the window frame and the support rod is a damping rotating shaft.

[0009] With the above structure, the end of the support rod is provided with an arc-shaped guide surface. When the arc-shaped guide surface contacts the edge of the slot, it can guide the support rod to be inserted into the slot along the arc surface. The window frame and the support rod are connected by a damping shaft. After the window frame is closed, the support rod is rotated to fit against the window frame. The resistance of the damping shaft prevents the support rod from shaking.

[0010] As a further improvement of this utility model, the mounting bracket is also provided with reinforcing ribs, and the reinforcing ribs are connected to the slide rails extending to one end of the side of the mounting bracket.

[0011] With the above structure, a reinforcing rib is set on the mounting bracket to connect the end of the slide rail that extends to the side of the mounting bracket. The mounting bracket is used to improve the structural strength of the slide rail and prevent the slide rail from bending downward.

[0012] As a further improvement of this utility model, the slide rail is provided with limiting blocks at both ends, and the limiting blocks are rubber pads.

[0013] With the above structure, after the movable seat slides to the end of the slide rail by opening and closing the window frame, the movable seat hits the limit block for braking. The limit block is a rubber pad, which buffers the collision with the movable seat and prevents damage to both.

[0015] like Figures 1-3 The diagram shows a basement smoke exhaust skylight that improves lighting performance. It includes a mounting bracket 1 and a window frame 2. The mounting bracket 1 is connected to a slide rail 3 and a gear shaft 4. The slide rail 3 is connected to the side of the mounting bracket 1 facing the interior and is arc-shaped with one end extending to the side of the mounting bracket 1. A movable seat 5 is also slidably connected to the slide rail 3. The gear shaft 4 is positioned corresponding to the center of the slide rail 3 and is actuated by a driven gear 6. The movable seat 5 is equipped with a smoke exhaust fan 7 and a linkage rod 8. One end of the linkage rod 8 is connected to the gear shaft 4. The window frame 2 is housed within the mounting bracket 1 and has a hinge shaft 9 actuated to the mounting bracket 1. The hinge shaft 9 is coaxially connected to a drive gear 10, which is a meshing bevel gear with the driven gear 6.

[0016] A drive gear 10 is connected to the hinge shaft 9 of the window frame 2, and a driven gear 6 is connected to the gear shaft 4. The drive gear 10 and the driven gear 6 are meshing bevel gears. When the window frame 2 is opened from the mounting bracket 1, the window frame 2 drives the hinge shaft 9 to rotate. The drive gear 10 rotates coaxially with the hinge shaft 9, driving the meshing driven gear 6 to rotate. The driven gear 6 drives the connected gear shaft 4 to rotate. One end of the linkage rod 8 is connected to the gear shaft 4 to move in a circular trajectory. The position of the gear shaft 4 corresponds to the center of the slide rail 3. As the linkage rod 8 moves, it pushes the moving seat 5 to move along the arc-shaped slide rail 3. The smoke exhaust fan 7 moves with the slide rail 3 to the bottom of the mounting bracket 1 and is aligned with the opened window frame 2. The smoke exhaust fan 7 is activated to blow air outwards from the skylight, accelerating the discharge of smoke and dust from the basement. Outdoors; during the closing of window frame 2, hinge shaft 9, drive gear 10, driven gear 6, and gear shaft 4 rotate in opposite directions, causing the moving seat 5 to slide onto the slide rail 3 and extend to one end of the mounting bracket 1. The smoke exhaust fan 7 moves to the side and is offset from the position of window frame 2. This prevents the smoke exhaust fan 7 from blocking window frame 2 when the window is not open for smoke exhaust, improving the lighting effect of the basement after the skylight is closed, and helping people to be exposed to sufficient sunlight when they are in the basement for a long time. When the skylight is opened, the smoke exhaust fan 7 is moved to the bottom of window frame 2 through the shaft and gear transmission, accelerating the exhaust of indoor smoke and dust. When closed, the smoke exhaust fan 7 moves to the side of the mounting bracket 1 and is offset from window frame 2, ensuring that there is sufficient space under window frame 2 for sunlight to enter the basement, improving the cold and damp indoor environment.

[0017] A rotatable support rod 11 is axially connected to one side of the window frame 2. The mounting bracket 1 has a slot 12 on the other side corresponding to the hinge shaft 9. The slot 12's opening direction, position, and size are all matched with the support rod 11.

[0018] After opening the window frame 2, rotate the support rod 11 to a position perpendicular to the hinge shaft 9. The end of the support rod 11 away from the window frame 2 is aligned downward and inserted into the slot 12, so that the mounting bracket 1, the window frame 2, and the support rod 11 form a stable triangular support structure, keeping the window frame 2 in the open state and avoiding accidental contact or the window frame 2 closing due to its own weight.

[0019] The end of the support rod 11 is provided with an arc-shaped guide surface, and the connecting shaft between the window frame 2 and the support rod 11 is a damping rotating shaft.

[0020] The end of the support rod 11 is provided with an arc-shaped guide surface. When the arc-shaped guide surface contacts the edge of the slot 12, it can guide the support rod 11 to be inserted into the slot 12 along the arc surface. The window frame 2 and the support rod 11 are connected by a damping shaft. After the window frame 2 is closed, the support rod 11 is rotated to fit against the window frame 2. The resistance of the damping shaft prevents the support rod 11 from shaking.

[0021] The mounting bracket 1 is also provided with a reinforcing rib 13, which is connected to the slide rail 3 and extends to one end of the side of the mounting bracket 1.

[0022] The mounting bracket 1 is equipped with reinforcing ribs 13 to connect the end of the slide rail 3 that extends to the side of the mounting bracket 1. The mounting bracket 1 is used to improve the structural strength of the slide rail 3 and prevent the slide rail 3 from bending downward.

[0023] The slide rail 3 is provided with limiting blocks 14 at both ends, and the limiting blocks 14 are rubber pads.

[0024] After the movable seat 5 is slid to the end of the slide rail 3 by opening and closing the window frame 2, the movable seat 5 hits the limit block 14 to brake. The limit block 14 is a rubber pad, which buffers the collision with the movable seat 5 to prevent damage to both.
