Description

Technical Field

[0001] The invention relates to a ventilation and smoke exhaust device, and in particular to a honeycomb type ventilation and smoke exhaust skylight. Background Art

[0002] At present, most smoke exhaust skylights on the market are only used for fire smoke exhaust. They cannot be used on windy days or rainy days, which makes it impossible for workshops that need ventilation to be ventilated normally. If a streamlined ventilator is used, the cost is particularly high, and the roof load is large. When using a thin ventilator, the effective ventilation area can only reach about 30-40%, and a larger area needs to be laid out on the factory roof to meet the ventilation and smoke exhaust requirements. For example, the invention patent with the authorization announcement number CN 219158200 U discloses a smoke exhaust skylight that is easy to ventilate. The opening and closing of the window is controlled by an electric push rod. On rainy days, the window can only be closed and cannot be ventilated. Therefore, a ventilation and smoke exhaust skylight with a large effective ventilation area, rain and snow protection, and both ventilation function and fire smoke exhaust function is urgently needed. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a honeycomb ventilation and smoke exhaust skylight, which is rain and snow proof, has a large ventilation area, a simple structure, is easy to assemble, has a large effective ventilation area, and has low wind resistance.

[0004] Specifically, the present invention discloses a honeycomb type ventilation and smoke exhaust skylight, comprising: a skylight base, on which a main frame is arranged; louvers, multiple layers of which are arranged on the main frame, each layer of louvers is arranged in parallel, and a water collecting trough is arranged at the bottom; a valve plate, which is arranged between the bottom layer of louvers and is connected to a driving assembly to drive rotation.

[0005] The benefit of adopting the above technical solution is that the multi-layer louvers can effectively prevent rainwater penetration and do not need to be closed when it is windy and rainy. In extreme weather, the valve plate can be closed, and a ventilation and smoke exhaust channel is formed between the parallel louvers, which has both ventilation and fire-fighting functions.

[0006] Furthermore, the louvers are arranged at an inclination, and the inclination directions of the louvers arranged up and down are opposite.

[0007] The advantage of adopting the above technical solution is that the louvers arranged in opposite inclined directions can prevent splashing rainwater from falling into the skylight, separate the rainwater layer by layer, and the rainwater flows out from both sides through the water collecting trough.

[0008] Furthermore, an outer protective plate is provided on the outer side of the main frame.

[0009] The benefit of adopting the above technical solution is that the outer protective plate plays a protective role, protecting the louver as a whole, preventing strong winds from damaging the main body of the skylight, and at the same time preventing rain and snow from entering the skylight from the side.

[0010] Furthermore, flashing plates are provided on both sides of the skylight foundation, the flashing plates are located below the louver plates, and are provided with water guides.

[0011] The benefit of adopting the above technical solution is that the flashing plate will drain the rainwater that falls on the outside of the louver, reduce the penetration of rainwater into the skylight foundation, reduce the entry of rainwater on the mounting plate, and the water guide will drain the rainwater.

[0012] Furthermore, the louver plate includes a louver plate body, an upper end of which is provided with a bending portion, and a lower end is integrally formed with the water collecting trough.

[0013] The benefit of adopting the above technical solution is that the setting of the bending part can play a blocking role to prevent rainwater from falling from the upper side of the louver. At the same time, the one-piece water collection trough can not only drain the rainwater, but also facilitate processing and installation, and there is no gap between it and the louver body, effectively preventing water.

[0014] Furthermore, the louver plate includes an upper louver, a middle louver and a lower louver, the upper louver and the lower louver have the same inclination direction, and the middle louver and the upper louver have an inclination direction opposite to that of the upper louver.

[0015] The advantage of adopting the above technical solution is that the three-layer louvers are waterproof layer by layer, and ventilation and smoke exhaust channels are formed between the louvers, which do not need to be closed in rainy weather, thereby meeting the ventilation function in windy and rainy weather.

[0016] Furthermore, the louver plate is a lighting plate or a non-lighting plate.

[0017] The benefit of adopting the above technical solution is that when better lighting effect is needed, a lighting board is used, which is a transparent board that allows sunlight to pass through; when the lighting function is not needed, a non-lighting board is used and is set according to needs.

[0018] Furthermore, a mounting groove is provided on the main frame, and the louver plate is installed in the mounting groove.

[0019] The advantage of adopting the above technical solution is that the installation groove is used to install and fix the louver, and the inclination angle of the installation groove is set according to needs, which is convenient for assembly. There is no need to adjust the angle of the louver on site, and it can be directly installed.

[0020] Furthermore, a basic flashing plate is arranged below the flashing plate, and the lower end of the basic flashing plate extends outward.

[0021] The benefit of adopting the above technical solution is that the provision of the basic flashing board can guide the water on the flashing board to the outside, thereby preventing rainwater from entering the inside of the skylight. BRIEF DESCRIPTION OF THE DRAWINGS

The louvers 3 arranged in opposite directions can prevent splashing rainwater from falling into the skylight, separate the rainwater layer by layer, and the rainwater flows out from both sides through the water collecting groove 31. The three-layer louvers 3 are waterproof layer by layer, and at the same time, ventilation and smoke exhaust channels are formed between the louvers 3, which do not need to be closed in rainy weather, meeting the ventilation function in rainy and snowy weather. At the same time, the multi-layer louvers 3 can be formed into a modular structure and arranged on the skylight base 1, which is convenient for installation and does not affect ventilation.

[0037] In some embodiments, the main frame 2 can adopt the following structural scheme, wherein an outer protective plate 5 is arranged on the outer side of the main frame 2, and the main frame 2 and the outer protective plate 5 are connected by a protective plate bracket, and the protective plate bracket is arranged on the outer side of the main frame 2. The setting of the protective plate bracket can facilitate installation and play a supporting role. The main frame 2 is stamped from a whole piece of steel plate, which is easy to manufacture. After installation, the frame plays a role of unit separation to reduce wind blowby. An installation groove 21 is arranged on the main frame 2, and the louver 3 is installed in the installation groove 21.

[0038] The benefit of adopting the above technical solution is that the outer protective plate 5 plays a protective role, protecting the louver 3 as a whole, preventing strong winds from damaging the main body of the skylight, and at the same time preventing rain and snow from entering the skylight from the side.

[0044] The benefit of adopting the above technical solution is that the provision of the basic flashing plate 62 can guide the water on the flashing plate 6 to the outside, thereby preventing rainwater from entering the interior of the skylight.

[0045] In some embodiments, the valve plate 4 may adopt the following structural scheme (eg Figure 4 As shown in the figure, a connecting shaft is installed in the middle of the valve plate 4, and a driving component is connected to one side of the valve plate 4. The driving component can be an electric push rod 7, which is hinged on the main frame 2. A 24V electric push rod 7 is used, which is safe to work. Each valve plate 4 can be driven by an electric push rod 7, or the valve plates 4 can be connected in series and an electric push rod 7 is set to control the switch. The valve plate 4 is tilted when closed, so that rainwater flows into the water collection tank 31 along the upper end of the valve plate 4, and then discharged to the outside of the skylight. When the valve plate 4 is opened, the inclination angle of the louver 3 is the same, which will not affect the ventilation and smoke exhaust.

[0046] In order to reduce air flow resistance, the effective ventilation size of each ventilation and smoke exhaust channel is basically the same during design, so that the effective ventilation area is more than 60%. The valve plate 4 is usually in an open state. When it is windy and rainy, the ventilation and smoke exhaust are not affected by rain. When there is extreme weather, the valve plate 4 can be closed to prevent rain and snow from entering. It can be installed on a flat or inclined roof (such as Figure 6 , 7 It has good rainproof effect.
