[0002] Maintaining good natural lighting indoors is a basic requirement for the indoor environment of buildings. Currently, most buildings use skylights or skylights to achieve natural lighting. For single-story buildings that use natural smoke exhaust, especially in large industrial buildings, the skylight is often a closed structure that only achieves the purpose of natural lighting. When a fire occurs in a building, the indoor smoke is mainly exhausted by the side windows. Due to the low density of high-temperature smoke, it will quickly rise and accumulate in the top space of the building and cannot be exhausted, posing a threat to the safety of indoor personnel.

[0003] Related technology discloses a skylight with smoke exhaust function, including a skylight bottom plate, a skylight bracket mounted on the upper end surface of the skylight bottom plate, and a skylight bonded to the skylight bracket, a sliding connecting rod hinged on the inner side of the skylight bracket, an ether temperature-sensitive bulb connected to the end of the sliding connecting rod, the other end of the ether temperature-sensitive bulb is connected to the skylight bottom plate, a sliding connecting rod support rod is hinged on the middle of the sliding connecting rod, the other end of the sliding connecting rod support rod is fixed to the skylight bottom plate, and the sliding connecting rod and the skylight bottom plate are connected by a curved memory metal strip. Related technology When high-temperature smoke gathers around the ether temperature-sensitive bulb during a fire, the ether temperature-sensitive bulb will burst, and the skylight moves upward under the action of the memory metal. At this time, the smoke exhaust shaft is connected to the outdoors, and the high-temperature smoke is quickly exhausted to the outdoors.

[0004] Although the related technology has realized the smoke exhaust treatment of the skylight, when the existing elliptical skylight encounters a fire incident, it is difficult to climb up and open the skylight, resulting in most of the smoke being unable to be exhausted in time. Even if the smoke is exhausted in time, it is still troublesome to clean up afterwards. Utility Model Content

[0045] Reference Figure 1 and Figure 2 The side of the skylight body 1 facing away from the ground is fixedly connected with a mounting column 11. There are two mounting columns 11, which are perpendicular to the ground and arranged opposite to each other. The skylight body 1 is elliptical, and a smoke exhaust hole for smoke exhaust is opened at the center. Compared with other skylights, the elliptical skylight helps to distribute natural light more evenly, reduce shadows, and improve the lighting effect in the entire building.

[0046] Reference Figure 2 and Figure 3 The smoke exhaust assembly 2 is slidably connected to the mounting column 11 along the length direction of the mounting column 11. The smoke exhaust assembly 2 includes a smoke exhaust plate 21. The smoke exhaust plate 21 is slidably connected to the mounting column 11. The smoke exhaust plate 21 is used to block or open the smoke exhaust hole. A plurality of smoke exhaust ports 211 are evenly arranged on the smoke exhaust plate 21. The smoke exhaust ports 211 can be opened and closed. When the smoke exhaust ports 211 are opened, the thick smoke in the room can be quickly and timely discharged to reduce the harm of the thick smoke to the people in the room. A heat-resistant layer is provided on the side of the bottom of the smoke exhaust plate 21 away from the ground. The heat-resistant layer can further realize the heat-resistant protection of the smoke exhaust plate 21 to avoid long-term exposure to reduce the service life of the smoke exhaust plate 21.

[0047] Reference Figure 2 and Figure 3 Since the elliptical skylight is usually located at the top of the building, it is generally difficult to clean. Once it is blackened by thick smoke, it is difficult to clean, which affects the appearance of subsequent use. For this purpose, a cleaning part 3 is provided. The cleaning part 3 is arranged on the mounting column 11. The cleaning part 3 is used to clean the smoke exhaust component 2 after smoke exhaust, making maintenance more convenient, and the smoke exhaust port 211 can be cleaned regularly. Since the smoke exhaust component 2 is slidably connected to the mounting column 11, the smoke can be more conveniently discharged by moving the smoke exhaust component 2 to the side away from the skylight. The cleaning part 3 includes

[0048] Reference Figure 2 and Figure 3 The smoke exhaust assembly 2 also includes a smoke exhaust blade 22, a drive motor 23 and a lifting member 24. The smoke exhaust blade 22 is arranged on the side of the smoke exhaust plate 21 away from the skylight roof body 1, that is, the bottom of the smoke exhaust plate 21. The drive motor 23 is installed on the smoke exhaust plate 21, and the output shaft of the drive motor 23 is fixedly connected to the smoke exhaust blade 22. The drive motor 23 is used to drive the smoke exhaust blade 22 to rotate. In this embodiment, there are three smoke exhaust blades 22, and the three smoke exhaust blades 22 are evenly distributed at the bottom of the smoke exhaust plate 21. The area of ​​the smoke exhaust blade 22 is larger than the area of ​​the smoke exhaust port 211. Under normal circumstances, the smoke exhaust blade 22 can block the smoke exhaust port 211. The smoke exhaust port 211 is evenly distributed on the smoke exhaust plate 21, and the thick smoke in the room can be evenly and effectively discharged through the smoke exhaust port 211, thereby quickly reducing the harm of the thick smoke to the indoor personnel during a fire. The smoke exhaust blade 22 is arranged on one side of the smoke exhaust plate 21 and is rotated by the drive motor 23. The operation of the smoke exhaust blades 22 can increase the smoke exhaust efficiency and further accelerate the exhaust of dense smoke. In addition, when the smoke exhaust assembly 2 is not working, the smoke exhaust blades 22 can block the smoke exhaust port 211 to prevent rain and snow from entering the room.

[0049] Reference Figure 2 and Figure 3The lifting member 24 is fixedly connected to the smoke exhaust plate 21, and the lifting member 24 is used to drive the smoke exhaust plate 21 to move along the height direction of the mounting column 11. The lifting member 24 drives the smoke exhaust plate 21 to move along the height direction of the mounting column 11, and then when a fire causes thick smoke, the smoke exhaust plate 21 can be moved to a side away from the skylight roof body 1, so that the thick smoke can flow out from between the skylight roof body 1 and the smoke exhaust plate 21, thereby improving the efficiency of smoke exhaust.

[0050] Reference Figure 2 and Figure 3 The lifting member 24 includes a nut 241, a screw rod 242 and a servo motor 243. The nut 241 is fixedly connected to the smoke exhaust plate 21. The screw rod 242 passes through the nut 241 and is threadedly connected to the nut 241. The screw rod 242 and the nut 241 form a screw rod 242 nut 241 sub-mechanism. The screw rod 242 rotates to drive the nut 241 to move along the height direction of the mounting column 11. The screw rod 242 nut 241 sub-mechanism can control the vertical movement of the smoke exhaust plate 21. This allows the smoke exhaust plate 21 to be accurately moved to the desired height position so as to exhaust smoke to the greatest extent. The output shaft of the servo motor 243 is fixedly connected to the screw rod 242 to drive the screw rod 242 to rotate. The drive motor 23 also uses a servo motor 243, and the two are electrically connected with a switch. The switch is set in the building for the convenience of the operator.

[0051] Reference Figure 2-Figure 4 The cleaning part 3 includes a nozzle 31, a nozzle 32 and a water tank 33. The nozzle 31 is fixedly connected to the mounting column 11. The nozzle 31 is arranged inside the mounting column 11 to avoid affecting the lifting of the smoke exhaust plate 21. The spray end of the nozzle 31 is aligned with the smoke exhaust plate 21. The nozzle 32 is fixedly connected to the nozzle 31, and the nozzle 32 is used to transport the liquid medium used to clean the smoke exhaust plate 21. The water tank 33 is fixedly connected to the mounting column 11, and a water storage tank is provided in the water tank 33. The nozzle 32 is plugged into the water tank 33 and communicates with the water storage tank. The water storage tank is used to collect rainwater from the outside for the nozzle 31 to clean the smoke exhaust component 2. The water storage tank can collect rainwater from the outside, so that the device can utilize natural resources, namely rainwater, instead of relying solely on the external water supply system. It ensures that the device can clean the smoke exhaust plate 21 under different conditions. In particular, when there is no stable water supply system or when there is a problem with the water supply system, it can still operate normally. The effect of using rainwater to clean the smoke exhaust plate 21 is achieved through the nozzle 31, the nozzle 32 and the water tank 33. In addition, since the spraying area of ​​the nozzle 31 is fixed, the smoke exhaust plate 21 is driven up and down by the lifting member 24, and the lifting plate is driven to rotate by the driving motor 23, which enables the nozzle 31 to clean a wider range of the smoke exhaust plate 21 area.

[0052] In other embodiments, a backup water source block (not shown) is further provided at the bottom of the water tank 33, wherein the backup water source is stored inside the backup water source block, and the backup water source block is interconnected with the spray pipe 32. With the above solution, when the water in the water tank 33 evaporates completely due to long-term drought, the backup water source can be used for emergency cleaning.

[0053] Reference Figure 4 , a filter screen 331 is arranged on the top of the water tank 33, and the filter screen 331 is arranged obliquely (not shown in the figure). The filter screen 331 is arranged on the top of the water tank 33 to prevent impurities in the air, such as large dust particles or catkins, from entering the water tank 33 and contaminating the washing water. The filter screen 331 is arranged obliquely, and when there is too much water in the water tank 33, the excess water can completely soak the filter screen 331, so that the filter screen 331 can be cleaned, thereby making the water tank 33 have a certain self-cleaning function.

[0054] The implementation principle of the embodiment of the present application is:

[0055] When a fire occurs, the smoke exhaust port 211 on the smoke exhaust plate 21 of the smoke exhaust assembly 2 will be opened by driving the driving motor 23, the smoke exhaust blades 22 start to operate, and the driving motor 23 rotates it. After the smoke exhaust plate 21 is opened, the smoke exhaust port 211 and the smoke exhaust blades 22 work together to quickly discharge the thick smoke from the smoke exhaust hole. The lifting member 24 drives the smoke exhaust plate 21 to move vertically along the mounting column 11, and moves the smoke exhaust plate 21 to the side away from the skylight, so that the thick smoke can be discharged from the smoke exhaust hole and the smoke exhaust efficiency can be improved. The smoke exhaust blades 22 keep rotating during the smoke exhaust process to ensure that the thick smoke is quickly discharged, and at the same time block the smoke exhaust port 211 when not working to prevent rain and snow from entering the room. During the process of cleaning the smoke exhaust assembly 2, the nozzle 31 and the nozzle 32 in the cleaning member 3 are used to spray cleaning liquid onto the smoke exhaust plate 21 to clean the smoke exhaust assembly 2. The water storage tank in the water tank 33 collects rainwater from the outside, and the nozzle 32 is connected to the water tank 33, and the rainwater is sprayed onto the smoke exhaust plate 21 through the nozzle 31 for cleaning. In the case of long-term drought, the backup water source in the backup water source block can be used for emergency cleaning of the smoke exhaust plate 21. The filter 331 is located at the top of the water tank 33 to prevent impurities from entering the water tank 33. The filter 331 is tilted so that excess water can clean itself and keep the water tank 33 clean.
