Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust skylight technology, and in particular to an automatic sensing smoke exhaust skylight. Background Technology

[0002] Smoke exhaust skylights, as an important component of modern architectural design and fire safety, have undergone numerous innovations and developments in their underlying technology. The design and application of smoke exhaust skylights aim to improve the ventilation performance of buildings, especially in emergencies such as fires, enabling the rapid and effective removal of smoke and harmful gases, thus creating favorable conditions for personnel evacuation and fire rescue.

[0003] With the acceleration of urbanization and the continuous increase in building height, traditional ventilation methods can no longer meet the needs of modern buildings for efficient and rapid smoke extraction. Therefore, smoke extraction skylights have emerged and, with their unique structure and function, have become an indispensable part of modern buildings.

[0004] Existing smoke exhaust skylights all use electric push rods to open and close, and the electric push rods also serve to support the skylights. There is a lack of other supporting structures for the skylights. However, when extreme strong winds occur at the same time as a fire, the pressure difference between the inside and outside caused by the fire may cause strong winds to backflow into the factory through the skylights. If the electric push rods are damaged by the instantaneous pressure when strong winds backflow, it may cause the skylights to close abnormally, preventing the dense smoke generated by the fire from being discharged in time. Utility Model Content

[0005] The purpose of this invention is to provide an automatic sensing smoke exhaust skylight to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic induction smoke exhaust skylight, including a smoke exhaust channel, a skylight body rotatably mounted on the top of the smoke exhaust channel, connecting plates fixedly mounted on both side walls of the smoke exhaust channel, a connecting shaft fixedly mounted on the bottom of the skylight body, the two ends of the connecting shaft being rotatably connected to the two connecting plates respectively, and a double-stroke component being provided between the connecting shaft and the connecting plates.

[0007] As a further description of the above technical solution: the dual-stroke assembly includes two connecting rods, which are slidably mounted at both ends of the connecting shaft. A dual-thread track groove is provided on the side wall of the connecting plate that contacts the connecting shaft, and the connecting rod is slidably disposed inside the dual-thread track groove.

[0008] As a further description of the above technical solution: a protrusion is provided at the fork of the dual-threaded trajectory slot.

[0009] As a further description of the above technical solution: two locking blocks are slidably installed at one end of the top of the dual-thread track groove, the two locking blocks are slidably connected to the connecting plate, and a spring is fixedly connected between the two locking blocks and the connecting plate.

[0010] As a further description of the above technical solution: electric push rods are rotatably installed on both sides of the inner wall of the smoke exhaust channel, and the output ends of the two electric push rods are rotatably connected to the bottom two side walls of the skylight body, respectively.

[0011] As a further description of the above technical solution: both ends of the connecting shaft are rotatably mounted with support rings, and the two support rings are fixedly mounted on both sides of the top of the smoke exhaust channel.

[0012] This invention provides an automatic sensor-activated smoke exhaust skylight. It offers the following advantages: During operation, the skylight body is opened and closed via an electric push rod. In the event of a fire and strong winds simultaneously, backdrafts may occur, potentially causing the electric push rod to be insufficient to support the skylight body. Therefore, a dual-stroke component is installed between the connecting shaft and the connecting plate. During normal use, the skylight body moves along its normal trajectory when resetting. When encountering backdrafts, the dual-stroke component causes the skylight to enter a different trajectory, locking the skylight body in place and ensuring it remains open. This effectively prevents abnormal closure of the skylight body due to backdrafts.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0014] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 An automatic sensing smoke exhaust skylight includes a smoke exhaust channel 1, a skylight body 2 rotatably mounted on the top of the smoke exhaust channel 1, connecting plates 3 fixedly mounted on both side walls of the smoke exhaust channel 1, and a connecting shaft 4 fixedly mounted on the bottom of the skylight body 2. The two ends of the connecting shaft 4 are rotatably connected to the two connecting plates 3 respectively. A double-stroke assembly is provided between the connecting shaft 4 and the connecting plates 3. During the use of this device, the skylight body 2 is opened and closed by an electric push rod 10. In the event of a fire and strong winds occurring simultaneously, strong winds may cause backflow, making the electric push rod 10 insufficient to support the skylight body 2. Therefore, a double-stroke assembly is provided between the connecting shaft 4 and the connecting plates 3. During normal use, the skylight body 2 moves along a normal travel trajectory when resetting. When encountering strong winds, the double-stroke assembly causes the skylight to enter another travel trajectory, locking the skylight body 2 and keeping it always open, effectively preventing abnormal closure of the skylight body 2 due to strong winds.

[0026] As a preferred technical solution in this embodiment, the dual-stroke assembly includes two connecting rods 5, which are slidably mounted at both ends of the connecting shaft 4. A dual-stroke trajectory groove 6 is provided on the side wall of the connecting plate 3 that contacts the connecting shaft 4. The connecting rods 5 are slidably disposed inside the dual-stroke trajectory groove 6. The dual-stroke trajectory groove 6 consists of a quarter-circular arc groove and a horizontal straight groove. During normal use, the electric push rod 10 drives the sunroof body 2 to close slowly, and the connecting rods 5 will closely adhere to the bottom of the arc groove in the dual-stroke trajectory groove 6, moving to the bottommost position, thus allowing the sunroof to close normally. This is used for the daily ventilation of the sunroof body 2. However, in the event of a fire in the factory and strong winds, due to the... The air inside the factory is hot due to the fire. When it is discharged along the smoke exhaust duct 1, it causes the air pressure inside the factory to drop, causing cold air from the outside to backflow. Combined with strong winds, the instantaneous backflow pressure may damage the electric push rod 10, causing the sunroof body 2 to close abnormally. At this time, the dual-thread track control comes into play. When the sunroof body 2 closes instantaneously, the connecting rod 5, which is slidably installed inside the connecting shaft 4, will remain in its original position for a period of time due to inertia without being subjected to other external forces. At this time, the instantaneous closing tendency of the sunroof body 2 will cause the connecting rod 5 to enter the horizontal straight groove of the dual-thread track control. When it reaches the end, the connecting rod 5 is stuck, preventing the sunroof body 2 from closing and preventing the abnormal closing of the sunroof body 2 caused by strong wind backflow.

[0027] As a preferred technical solution in this embodiment, a protrusion 7 is provided at the fork of the dual-thread track groove 6; when the sunroof body 2 is closed normally, the sunroof rotates slowly, and the connecting rod 5 enters the arc groove of the dual-thread track groove 6 along the protrusion 7. When the sunroof body 2 is closed instantly by strong wind backflow, the connecting rod 5 is lifted when it passes the protrusion 7, and the auxiliary connecting rod 5 enters the horizontal straight groove of the dual-thread track groove.

[0028] As a preferred technical solution in this embodiment, two locking blocks 8 are slidably installed at one end of the top of the dual-thread track groove 6. The two locking blocks 8 are slidably connected to the connecting plate 3, and a spring 9 is fixedly connected between the two locking blocks 8 and the connecting plate 3. A ramp is provided on one side of the top of the two locking blocks 8, with the ramp facing the fork of the dual-thread track groove 6. When the connecting rod 5 enters the end of the horizontal straight groove of the dual-thread track groove 6, the locking block 8 limits the connecting rod 5 to prevent the connecting rod 5 from rebounding.

[0029] As a preferred technical solution in this embodiment, electric push rods 10 are rotatably installed on both sides of the inner wall of the smoke exhaust channel 1, and the output ends of the two electric push rods 10 are rotatably connected to the bottom two side walls of the sunroof body 2 respectively; the opening and closing of the sunroof body 2 are accomplished by the extension or retraction of the output ends of the electric push rods 10. In addition, the electric push rods 10 are electrically connected to the smoke sensor inside the factory. When the smoke sensor detects a smoke signal, it transmits it to the electric push rods 10 in the form of an electrical signal, and the electric push rods 10 open the sunroof body 2 in time.

[0030] As a preferred technical solution in this embodiment, support rings 11 are rotatably installed at both ends of the connecting shaft 4, and the two support rings 11 are fixedly installed on both sides of the top of the smoke exhaust channel 1; the connection between the connecting rings and the connecting shaft 4 is rotatably connected to increase the stability of the connection of the sunroof body 2.
