Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust skylight technology, specifically to a smoke exhaust skylight with an adjustment mechanism. Background Technology

[0002] A smoke exhaust skylight is a ventilation device installed on the roof or other parts of a building to expel smoke, heat, and other harmful gases from the building to the outside in emergencies such as fires or for normal ventilation needs, while simultaneously introducing fresh air to improve indoor air quality and environmental conditions. It plays a vital role in protecting lives, reducing fire losses, and maintaining a normal working and living environment within the building. The working principle of a smoke exhaust skylight is primarily based on the principle of airflow. During a fire, the indoor temperature rises, and smoke and heat rise. When the indoor pressure exceeds the outdoor pressure, the smoke and heat are expelled through the smoke exhaust skylight. Simultaneously, fresh outdoor air enters the building from other vents or windows, creating air convection, thus achieving the purpose of smoke extraction and ventilation. It is widely used in industrial, commercial, and public buildings.

[0003] However, existing smoke exhaust skylights lack a structure with dual motors independently controlling the window panels, making it impossible to dynamically adjust the opening of the window panels on both sides according to the distribution of smoke concentration during a fire. This results in low smoke exhaust efficiency. Furthermore, existing smoke exhaust skylights tend to leave gaps when closed, which cannot effectively block the penetration of rainwater, dust, and external noise, leading to poor smoke exhaust efficiency and energy-saving effects. Therefore, we propose a smoke exhaust skylight with an adjustment mechanism. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a smoke exhaust skylight with an adjustment mechanism. This new smoke exhaust skylight is equipped with a structure of dual motors independently controlling the window panels, which can dynamically adjust the opening of the window panels on both sides according to the distribution of fire smoke concentration. It also has the function of blocking rainwater, dust and external noise penetration, thereby effectively improving the smoke exhaust efficiency and energy-saving effect of the smoke exhaust skylight.

[0005] The technical solution adopted by this utility model to solve its technical problem is a smoke exhaust skylight with an adjustment mechanism, including a smoke exhaust skylight frame, a first window plate, a second window plate, a first servo motor, and a second servo motor. The first window plate and the second window plate are respectively arranged at both ends inside the smoke exhaust skylight frame. The first servo motor is arranged at one end of the smoke exhaust skylight frame. The output end of the first servo motor is connected to a first connecting rod. A first transmission block is arranged on the top of the first window plate. One end of the first connecting rod is connected to the first transmission block through a first connecting plate and screws. The other end of the smoke exhaust skylight frame is equipped with a second servo motor. The output end of the second servo motor is connected to a second connecting rod. The bottom of the second window panel is equipped with a second transmission block. One end of the second connecting rod is connected to the second transmission block through a second connecting plate and bolts.

[0006] By adopting the above technical solution, this new type of smoke exhaust skylight is equipped with a structure of dual motors independently controlling the window panels. It can dynamically adjust the opening of the window panels on both sides according to the distribution of smoke concentration in a fire. It also has the function of blocking rainwater, dust and external noise penetration, thereby effectively improving the smoke exhaust efficiency and energy-saving effect of the smoke exhaust skylight.

[0007] Specifically, a sliding groove is provided on the inner side of the smoke exhaust skylight frame, and both sides of the No. 1 window panel and the No. 2 window panel are located inside the sliding groove.

[0008] By adopting the above technical solution, the cooperation of window panel No. 1, window panel No. 2 and sliding track can be used to ensure the smooth movement of window panels by physical constraints, avoiding shaking or derailment caused by external forces.

[0009] Specifically, a No. 1 sealing strip is provided on both sides of the No. 1 window panel, and a No. 2 sealing strip is provided on both sides of the No. 2 window panel.

[0010] Specifically, a mounting base is provided at one end of the smoke exhaust skylight frame, a servo motor is located on the top of the mounting base, a clamp is provided around the servo motor, and both ends of the bottom of the clamp are connected to the mounting base by screws.

[0011] Specifically, a second mounting base is provided at the other end of the smoke exhaust skylight frame, a second servo motor is located on the top of the second mounting base, a second clamp is provided around the second servo motor, and both ends of the bottom of the second clamp are connected to the second mounting base by bolts.

[0012] By adopting the above technical solutions, mounting base No. 1 and mounting base No. 2 simplify the assembly process of servo motor No. 1 and servo motor No. 2, making it easier to disassemble and repair later. Clamp No. 1 and clamp No. 2 can respectively enhance the stability of servo motor No. 1 and servo motor No. 2.

[0013] The beneficial effects of this utility model are: The smoke exhaust skylight with an adjustment mechanism described in this utility model has a No. 1 servo motor and a No. 2 servo motor that can precisely drive the No. 1 window panel and the No. 2 window panel to move horizontally along the slide. By adopting the independent control of the No. 1 servo motor and the No. 2 servo motor, the opening of the two window panels can be dynamically adjusted according to the distribution of fire smoke concentration, thereby optimizing the smoke exhaust efficiency and avoiding the risk of overall failure due to the failure of a single motor.

[0014] The smoke exhaust skylight with an adjustment mechanism described in this utility model not only limits the sliding of the first and second window panels to prevent the window panels from shifting due to wind load or vibration, but also effectively reduces the frictional resistance when the first and second window panels slide, thereby enhancing the stability of the sliding of the first and second window panels.

[0015] The smoke exhaust skylight with an adjustment mechanism described in this utility model features a No. 1 sealing strip and a No. 2 sealing strip that enhance the tightness between the No. 1 and No. 2 window panels and the smoke exhaust skylight frame when closed. This effectively blocks the infiltration of rainwater, dust, and external noise, solving the problem of gaps easily left when traditional rotary skylights are closed. This significantly improves the building's airtightness and energy-saving effect. At the same time, the independent sealing structure of the No. 1 and No. 2 window panels allows the other side to remain sealed when one side of the window panel is opened, flexibly adapting to different smoke exhaust needs.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In order to utilize dual motors for independent control of the window panels, thereby effectively improving the smoke extraction efficiency and energy-saving effect of the smoke exhaust skylight, such as... Figure 1-5As shown, the smoke exhaust skylight with an adjustment mechanism of the present invention includes a smoke exhaust skylight frame 1, a first window panel 2, a second window panel 3, a first servo motor 4, and a second servo motor 5. The first window panel 2 and the second window panel 3 are respectively arranged at both ends inside the smoke exhaust skylight frame 1. The first servo motor 4 is arranged at one end of the smoke exhaust skylight frame 1. The output end of the first servo motor 4 is connected to a first connecting rod 7. The top of the first window panel 2 is provided with a first transmission block 8. One end of the first connecting rod 7 is connected to the first transmission block 8 through a first connecting plate 9 and screws. The other end of the smoke exhaust skylight frame 1 is equipped with a second servo motor 5. The output end of the second servo motor 5 is connected to a second connecting rod 13. The bottom of the second window panel 3 is equipped with a second transmission block 15. One end of the second connecting rod 13 is connected to the second transmission block 15 through a second connecting plate 14 and bolts.

[0021] In use, the slide groove 6 serves as a key guiding structure. Its surface is treated with a low-friction coating, which can reduce the frictional resistance when the first window panel 2 and the second window panel 3 slide. Both sides of the first window panel 2 and the second window panel 3 are located inside the slide groove 6. Therefore, the slide groove 6 can limit the sliding of the first window panel 2 and the second window panel 3, which can prevent the window panels from shifting due to wind load or vibration, thereby improving the stability of sliding. The No. 1 sealing strip 10 and the No. 2 sealing strip 16 can fill the gap between the No. 1 window panel 2 and the No. 2 window panel 3 and the smoke exhaust skylight frame 1, so that the No. 1 window panel 2 and the No. 2 window panel 3 can fit tightly against the frame when the smoke exhaust skylight frame 1 is closed, effectively blocking the penetration of rainwater, dust and external noise, solving the problem of easy gaps when the traditional rotating skylight is closed, significantly improving the building's airtightness and energy-saving effect. At the same time, the independent sealing structure of the double window panels of the No. 1 window panel 2 and the No. 2 window panel 3 allows the other side to remain sealed when one side of the window panel is opened, flexibly adapting to different smoke exhaust needs; Both servo motor 4 and servo motor 5 can precisely adjust their speed and direction according to the control signal. They can drive window panel 2 and window panel 3 to move horizontally along the slide rail 6 through connecting rod 7, transmission block 8, connecting rod 13, and transmission block 15, respectively, to achieve precise control of the opening angle. By adopting independent control of dual motors, the opening of the two window panels can be dynamically adjusted according to the distribution of fire smoke concentration, optimizing smoke exhaust efficiency, while avoiding the risk of overall failure due to single motor failure.

[0022] For example, such as Figure 1 , Figure 2 As shown, a sliding groove 6 is provided on the inner side of the smoke exhaust skylight frame 1, and both sides of the first window panel 2 and the second window panel 3 are located inside the sliding groove 6.

[0023] During use, the cooperation of window panel 2, window panel 3 and sliding track 6 can ensure the smooth movement of the window panels by means of physical constraints, avoiding shaking or derailment caused by external forces.

[0024] For example, such as Figure 2 , Figure 3 As shown, a No. 1 sealing strip 10 is provided on both sides of the No. 1 window panel 2, and a No. 2 sealing strip 16 is provided on both sides of the No. 2 window panel 3.

[0025] When in use, the No. 1 sealing strip 10 and the No. 2 sealing strip 16 can effectively block the penetration of rainwater, dust and external noise.

[0026] For example, such as Figure 1 , Figure 3 , Figure 5 As shown, a mounting base 11 is provided at one end of the smoke exhaust skylight frame 1, a servo motor 4 is provided on the top of the mounting base 11, and a clamp 12 is provided around the servo motor 4. Both ends of the bottom of the clamp 12 are connected to the mounting base 11 by screws.

[0027] For example, such as Figure 1 , Figure 3 , Figure 5 As shown, a second mounting base 17 is provided at the other end of the smoke exhaust skylight frame 1. The second servo motor 5 is located on the top of the second mounting base 17. A second clamp 18 is provided around the second servo motor 5. Both ends of the bottom of the second clamp 18 are connected to the second mounting base 17 by bolts.

[0028] In use, mounting base 11 and mounting base 17 simplify the assembly process of servo motor 4 and servo motor 5, making it easier to disassemble and repair later. Clamp 12 and clamp 18 can enhance the stability of servo motor 4 and servo motor 5 respectively.

[0029] In use, the smoke exhaust skylight frame 1, which serves as the basic support structure, is fixed to a predetermined position on the building roof. The sliding groove 6 inside the frame is a key guiding structure. Its surface is treated with a low-friction coating to reduce the frictional resistance when the first window panel 2 and the second window panel 3 slide. Both sides of the first window panel 2 and the second window panel 3 are located inside the sliding groove 6. Therefore, the sliding groove 6 can limit the sliding of the first window panel 2 and the second window panel 3, preventing the window panels from shifting due to wind load or vibration, thereby improving the stability of sliding. Compared with traditional rotating skylights that require complex transmission components such as hinges and support rods, this embodiment achieves horizontal movement through the sliding groove, which simplifies the mechanical structure and reduces the failure rate and maintenance costs. Furthermore, when window panel 2 and window panel 3 are installed inside the smoke exhaust skylight frame 1 and both sides are located in the sliding groove 6, sealing strip 10 and sealing strip 16 can fill the gap between window panel 2 and window panel 3 and the smoke exhaust skylight frame 1. Both sealing strip 10 and sealing strip 16 are made of EPDM rubber material with good elasticity and weather resistance, which can enhance the deformation adaptability. When the window panel is closed, it fits tightly against the frame, effectively blocking rainwater, dust and external noise penetration, solving the problem of easy gaps when traditional rotating skylights are closed, significantly improving the building's airtightness and energy-saving effect. At the same time, the independent sealing structure of the double window panels of window panel 2 and window panel 3 allows the other side to remain sealed when one side of the window panel is opened, flexibly adapting to different smoke exhaust needs. Furthermore, both servo motor 4 and servo motor 5 can precisely adjust their speed and direction according to the control signal, and can drive window panel 2 and window panel 3 to move horizontally along the slide rail 6 respectively, so as to achieve precise control of the opening angle. Compared with the traditional manual or pneumatic drive method, this new smoke exhaust skylight adopts independent control of dual motors, which can dynamically adjust the opening of the two window panels according to the distribution of fire smoke concentration, optimize smoke exhaust efficiency, and avoid the risk of overall failure due to single motor failure.
