Description

Technical Field

[0001] The invention relates to the technical field of skylights, and in particular to an array type smoke exhaust and lighting skylight system. Background Art

[0002] Smoke exhaust skylight refers to a product suitable for the roof of a building that integrates a series of functions such as lighting, smoke exhaust, ventilation, and heat exhaust. Depending on the function, it can also be called a lighting skylight. Most skylights can be divided into triangular, straight, arched, wind-proof, side-opening and other types. During use, the opening of the skylight can be controlled by three methods: ordinary control method, intelligent control method, and intelligent network control method. These three methods all have fire joint control functions.

[0003] The working principle of the smoke exhaust and lighting skylight is to adopt a pneumatic or electric window-pushing principle, and to open and close when the gas source is obtained or the voltage is started; the smoke, hot air, and heat generated during combustion or due to increased temperature gather at the top of the building to form smoke, which accumulates thicker and thicker in a short period of time and quickly spreads to the entire building space. The fire control system in the building quickly opens the windows on the top of the building for smoke exhaust and ventilation after the central control box receives the fire signal, so that the increasing smoke, heat, and hot gas can be discharged in the initial stage of formation. At the same time, when closed, the transparent material on the skylight can let in outdoor light, which has the effect of supplementing transparency for lighting. However, as Chinese patent application No.: 202310780138.7 discloses a double-opening skylight, but this skylight only forms an opening that can be opened and closed on the roof of the building, which leads to slower air convection inside and outside the building, causing the turbid air in the room to accumulate below the building, and the use effect is poor. Therefore, it is necessary to improve the existing smoke exhaust skylight so that it can adapt to the current needs for the use of smoke exhaust and lighting skylights. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the skylight smoke exhaust and lighting in the prior art, and to provide an array type smoke exhaust and lighting skylight system.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: an array-type smoke exhaust and lighting skylight system, including a mounting seat, a base is arranged on the upper part of the mounting seat, an opening fan is hingedly arranged on the upper part of the base, and a movable fan is arranged on the inner surface of the opening fan. After the opening fan is opened, the movable fan is combined with the opening fan through a driving device to form an exhaust duct higher than the base. A plurality of the mounting seats and the opening fans are arranged in an array on the top of the building.

[0006] Furthermore, the mounting seat includes a mounting plate connected to the roof, and the mounting plate is provided with mounting holes.

[0007] Furthermore, the sash comprises a support frame, a light-transmitting plate is arranged inside the support frame, at least two sashes are arranged opposite to each other, and an electric push rod is arranged inside the base and is hinged to the sash.

[0008] Furthermore, the inner surface of the open fan is provided with two parallel slide grooves, a slider is provided inside the slide groove, the driving device includes a screw rod arranged inside the slide groove, the slider is slidably arranged on the screw rod, and one end of the movable fan is hinged to the slider through a connecting device.

[0009] Furthermore, a top rod for pressing the moving fan is hingedly provided at the other end of the moving fan, the bottom of the top rod is hingedly connected to the support frame, and the top of the top rod is hingedly connected to the moving fan through a connecting block.

[0010] Furthermore, a sleeve is slidably provided on the top of the push rod, the end of the sleeve is hinged to the connecting block, the upper side of the connecting block is provided with an inclined surface, and a limiting block matching the inclined surface is provided on the support frame.

[0011] Furthermore, the connecting device includes a fixed tube arranged on the sliding block, a rotating shaft connected to the movable fan is arranged inside the fixed tube, and a spring is arranged at the lower part of the rotating shaft.

[0012] Furthermore, a stopper for pressing down the movable fan is provided on the side of the support frame.

[0013] The beneficial effects of the embodiments of the present invention are as follows: when smoke or air exhaust is required, the angle between the movable fan and the open fan is changed so that the movable end of the movable fan fits against the boss on the other open fan, and when the movable fans on both sides are extended, a chimney-shaped exhaust pipe is formed. The exhaust pipe has a certain height, which is higher than the top of the building. A chimney effect is formed when exhausting smoke or drawing air, and the air inside the building is replaced. When the weather is hot or the air inside the building is turbid, it is opened to allow fresh air to enter the building from the windows or doors at the bottom, and most of the hot air or turbid air is discharged from the top. At the same time, the open fan and the movable fan do not affect the lighting, thereby ensuring the lighting and smoke exhaust effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0026] See also Figures 1 to 10 The embodiment of the present invention discloses an array type smoke exhaust and lighting skylight system, which mainly includes a mounting base 1, a base 101, an opening fan 2 and a movable fan 3 arranged on a building. The mounting base 1 is designed to be firmly installed on the roof of the building, and the base 101 is fixed on the upper part thereof. The specific structure of the mounting base 1 includes a mounting plate tightly connected to the roof, and the mounting plate is provided with mounting holes, so that the mounting base 1 can be firmly fixed to the roof of the building by bolts or other fasteners. The mounting base 1 can be adjusted according to the slope of the building to ensure the stability after installation. At the top of the building, the mounting base 1 and the opening fan 2 are distributed in an array manner to maximize the smoke exhaust and lighting effects. Generally speaking, the roof of a factory building is generally large in area, and multiple skylights are installed in an array manner to improve the lighting and smoke exhaust effects and ensure the use effect.

[0027] The upper part of the base 101 is connected to the sash 2 by a hinge, so that the sash 2 can be flexibly opened and closed. In this embodiment, the base 101 adopts a rectangular frame, and the base 101 is higher than the mounting plate, providing a higher installation space, so that the sash 2 can be stably erected after opening, and only a small part is higher than the building after closing, ensuring stability during use. The two sashes 2 arranged opposite each other can increase the light-transmitting area and improve the lighting effect. When opened, the opening area can be guaranteed to the greatest extent, increasing the area of ​​smoke exhaust or ventilation, and ensuring the use effect.

[0028] The sash 2 is composed of a support frame 202 and a light-transmitting plate. The support frame 202 is a solid structure for supporting and protecting the light-transmitting plate inside. The light-transmitting plate is made of transparent or translucent material and can provide natural light required for the room when the sash 2 is closed. The sash 2 is designed to be at least two, which are arranged opposite to each other to form an openable window. The inner surface of the sash 2 is provided with a movable sash 3. A sealing strip is provided on the surface of the support frame 202 to ensure the sealing effect when the sash 2 is closed, prevent water leakage in rainy weather, and ensure the use efficiency. The support frame 202 is provided with a corresponding frame according to the use requirements, and a slide groove 203 is provided on the upper and lower frames of the support frame 202, and the two slide grooves 203 are parallel to each other, and a slider 4 is provided inside the slide groove 203. The driving device includes a screw rod 205 provided inside the slide groove 203, and a driving motor 206 is provided outside the support frame 202. The driving motor 206 adopts a waterproof motor, and a bevel gear is provided at the end of the screw rod 205 to connect with the driving motor 206, so that the screw rod 205 The slider 4 is driven to slide inside the slide groove 203, thereby driving the frame of the movable fan 3 to move to one side, realizing the function of changing the angle between the open fan 2 and the movable fan 3. The slider 4 slides on the screw rod 205, and one end of the movable fan 3 is connected to the slider 4 through a connecting device. When the screw rod 205 rotates, the slider 4 drives the movable fan 3 to move along the slide groove 203. The movable fan 3 is also composed of a frame and a light-transmitting plate, and one end of the movable fan 3 is hinged with the slider 4. When the open fan 2 is opened, the movable fan 3 is driven to move along the slide groove 203. Under the action of the motor 206 and the screw rod 205, it can be combined with the opposite open fan 2 to form an exhaust duct higher than the base 101. A boss 204 is arranged on the support frame 202, and the side of the boss 204 is arranged as an inclined surface. The moving end of the movable fan 3 abuts against the side of the boss 204, and a sealing gasket is arranged on the inclined surface of the boss 204 to reduce the gap between the movable fan 3 and the boss 204, so that a chimney-shaped exhaust duct is formed. Compared with just opening the open fan 2 for ventilation and smoke exhaust, the smoke exhaust and ventilation efficiency is greatly improved.

[0029] An electric push rod 201 is provided inside the base 101 for driving the opening and closing of the sash 2. A crossbeam 102 is provided in the middle of the base 101. When the sash 2 is closed, the side of the support frame 202 is pressed onto the crossbeam 102 to ensure the sealing and stability when closed, and the frame of the movable sash 3 does not contact the crossbeam 102. A support frame is provided on the lower surface of the crossbeam 102. The electric push rod 201 is hinged on the support frame, and the other end of the electric push rod 201 is hinged on the boss 204, so that the electric push rod 201 and the support frame 202 always have an angle, which is convenient for adjusting the opening and closing of the sash 2 according to the usage conditions, and can control the opening angle, which is convenient to use and simple to control, and ensures the usage effect.

[0030] In order to increase the stability of the movable fan 3, a top rod 301 is hingedly provided at the other end thereof, and a receiving cavity for receiving the top rod 301 is horizontally provided on the support frame 202 of the open fan 2, so that the open fan 2 and the movable fan 3 are more tightly fitted, reducing interference with the movable fan 3 and improving the use effect. The bottom of the top rod 301 is hinged to the support frame 202, and the top is hinged to the movable fan 3 through the connecting block 303. A reset groove 5 for receiving the connecting block 303 is provided at the end of the receiving cavity, and the side of the reset groove 5 is provided with an inwardly inclined surface, and the side of the connecting block 303 is designed as an inclined surface, so that the movable fan 3 When resetting, the end of the connecting block 303 enters the reset groove 5 and has a force toward the support frame 202, so that the movable fan 3 is more closely attached to the support frame 202, and a limit block 501 is arranged on the upper part of the reset groove 5, so that the movable fan 3 can be accurately reset, and the error formed after each action is reduced. The bottom of the limit block 501 is an inclined surface, so that the movable fan 3 can have a smaller downward force when resetting, thereby ensuring the stability of the movable fan 3, preventing the movable fan 3 from interfering with the cross beam 102, and preventing the movable end of the movable fan 3 from falling downward, thereby improving the use effect and making the movable fan 3 The movable fan 3 can remain stable during the opening and closing process, and is convenient to be combined with the open fan 2 to form an exhaust duct. A sleeve 304 is also slidably provided on the top of the top rod 301, and the end of the sleeve 304 is hinged to the connecting block 303. When in use, there is a certain moving distance between the sleeve 304 and the top rod 301, so that when the movable fan 3 starts to move to the left, the resistance of the top rod 301 when it is placed horizontally is prevented, so that the movable fan 3 can change the fitting angle more smoothly. The top rod 301 uses an electric push rod or a cylinder. When the slider 4 moves to the far left, the top rod 301 extends to change the distance between the movable fan 3 and the open fan 2. The angle between them makes the moving end of the movable fan 3 fit with the boss 204 on the other open fan 2. When the movable fans 3 on both sides are extended, a chimney-shaped exhaust pipe is formed. The exhaust pipe has a certain height after being formed, which is higher than the top of the building. A chimney effect is formed when exhausting smoke or drawing air, and the air inside the building is replaced. When the weather is hot or the air inside the building is turbid, it is opened to allow fresh air to enter the building from the windows or doors at the bottom, and most of the hot air or turbid air is exhausted from the top. At the same time, the open fan 2 and the movable fan 3 do not affect the lighting, thereby ensuring the lighting and exhaust effects.

[0031] The connecting device includes a fixed tube 401 and a rotating shaft 402 arranged on the slider 4, the rotating shaft 402 is inserted into the interior of the fixed tube 401, the rotating shaft 402 is connected to the movable fan 3, a stopper is arranged at the lower part of the rotating shaft 402, a spring 403 is arranged at the lower part of the stopper, the spring 403 is wound around the lower part of the rotating shaft 402, and a stopper 302 for pressing down the movable fan 3 is also arranged on the side of the support frame 202, the stopper 302 is arranged at one end near the free end, during the closing process of the movable fan 3, the end of the movable fan 3 connected to the slider 4 gradually approaches the stopper 302, and an auxiliary plate 103 is arranged in the width direction of the base 101, the auxiliary plate 103 is arranged according to the final moving position of the movable fan 3, after the movable fan 3 is in a stable state, the sealing between the base 101 and the movable fan 3 is ensured, and at the same time on the auxiliary plate 103 A groove is also provided for accommodating the stop block 302 to ensure the sealing of the open fan 2 after it is closed. When in use, when the movable fan 3 moves to the bottom of the stop block 302, the top of the support frame 202 is provided with an inclined surface which abuts against the inclined surface on the bottom block, thereby compressing the spring 403, pressing the movable fan 3 downward as a whole, so that the bottom of the movable fan 3 fits more closely to the bottom, ensuring the sealing between the movable fan 3 and the auxiliary plate 103, improving the exhaust effect of the exhaust duct formed, and preventing smoke and heat leakage. The design of the spring 403 allows the movable fan 3 to automatically reset and lift up when closed, while providing a certain buffering effect, increasing the gap between the auxiliary plate 103 and the movable fan 3, preventing the movable fan 3 from interfering with and rubbing against the auxiliary plate 103 when moving, protecting the movable fan 3 and the open fan 2 from damage, and improving the use effect.

[0032] There are multiple skylights arrayed on the top of large buildings, which not only have efficient smoke exhaust and ventilation functions, but also can provide sufficient indoor lighting when closed. At the same time, its structure is compact, stable and reliable. The exhaust duct formed when opened can accelerate the smoke exhaust effect and meet the smoke exhaust and lighting needs of various building roofs.
