Description

Technical Field

[0001] This invention relates to the field of smoke exhaust skylight technology, specifically to an intelligent smoke exhaust skylight based on photovoltaic power generation. Background Technology

[0002] Smoke exhaust skylights are fire-fighting equipment on factory roofs. They are commonly used for ventilation and smoke extraction between the inside and outside of the factory, as well as for lighting, ventilation, and smoke extraction within the factory. Smoke exhaust skylights create movement in the space, allowing internal air to flow out and achieving air circulation.

[0003] Existing smoke exhaust skylights mostly rely on free airflow and exchange for smoke discharge, which cannot achieve the effect of quickly discharging smoke into the outside air. Furthermore, they only have one opening method, making it difficult to adapt to various weather conditions. This fails to achieve the optimal usage mode of smoke exhaust skylights and greatly reduces their effectiveness.

[0004] Therefore, it is necessary to provide an intelligent smoke exhaust skylight based on photovoltaic power generation to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent smoke exhaust skylight based on photovoltaic power generation, in order to solve the problems of the above-mentioned background technology, which cannot achieve the effect of quickly exhausting smoke into the outside air, and has only one opening method, making it difficult to adapt to various weather conditions and failing to achieve the optimal use of the smoke exhaust skylight, thus greatly reducing the effectiveness of the smoke exhaust skylight. The technical solution of this invention addresses the problem of the overly simplistic nature of existing technical solutions and provides a solution that is significantly different from existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent smoke exhaust skylight based on photovoltaic power generation, comprising a ground with a convex structure, a smoke exhaust channel penetrating the top of the ground below the ground, the top of the smoke exhaust channel being inclined and having a transparent glass plate, a rotating rod rotatably connected to a rotating frame at the front and rear ends of the inclined end of the transparent glass plate, and the bottom of the rotating frame being fixed to the top of the ground, a driving component for driving the transparent glass plate to rotate at one end of the top of the ground, a photovoltaic module glass plate at the top of the transparent glass plate, a connecting rail at the front and rear ends of the bottom of the photovoltaic module glass plate, a limit mechanism between the connecting rail and the transparent glass plate, a wind cup assembly connected to the transparent glass plate at one end of the connecting rail, and a fan assembly for quickly exhausting smoke inside the smoke exhaust channel.

[0007] Preferably, the drive assembly includes a drive motor mounted on the ground, the output end of the drive motor is connected to a first drive gear, the front end rotating rod of the transparent glass plate passes through the front end face of the rotating frame and is connected to a second drive gear, and the outer walls of the first drive gear and the second drive gear are provided with transmission chains.

[0008] Preferably, a telescopic rod is installed at the front and rear ends of the recessed part of the ground, a universal joint is connected to the top of the telescopic rod, a mounting base is connected to the top of the universal joint, and an electric rod is installed inside the mounting base.

[0009] Preferably, the limiting mechanism includes a groove formed inside the connecting track, a slider adapted to the groove is provided inside the groove, a fixing rod is provided at the front and rear ends of one end of the transparent glass plate and is rotatably connected to the slider, and a through hole communicating with the groove is provided at the opposite end of the connecting track.

[0010] Preferably, one end of the fixing rod extends through to the outside of the connecting rail and is welded to a rotating sleeve. The rotating sleeve is rotatably connected to the shaft of the wind cup assembly, and the bottom of the shaft is connected to a first meshing gear.

[0011] Preferably, the fan assembly includes fixed plates equidistantly fixed to the inner wall of the smoke exhaust duct. A motor housing is provided at one end of the fixed plates opposite each other. A servo motor is installed inside the motor housing. The output end of the servo motor is connected to a fan with a rotating shaft. An annular groove is formed in the inner wall of the smoke exhaust duct. A toothed ring plate is provided inside the annular groove. A connecting plate is installed on the inner side of the toothed ring plate and mounted on the outer wall of the fan blades. A through groove is formed at the front end of the inner wall of the smoke exhaust duct.

[0012] Preferably, the bottom of the annular groove is provided with an annular limiting groove, and a ball bearing is provided inside the annular limiting groove.

[0013] Preferably, a rotating shaft fixed to the top of the ground is installed in front of the smoke exhaust duct via a bearing. The top of the rotating shaft is connected to a second meshing gear that meshes with the first meshing gear. A third meshing gear that meshes with a gear ring plate is also installed on the outer wall of the rotating shaft.

[0014] Preferably, a battery and a controller are also installed on the top of the ground, and an alarm is installed on the inner wall of the smoke exhaust duct. The battery, controller, and alarm are all electrically connected.

[0015] Compared with the prior art, the beneficial effects of the present invention are: When the present invention is working normally, the first drive gear is driven to rotate by the drive motor, which in turn drives the second drive gear to rotate through the transmission chain, thereby driving the transparent glass plate to rotate and opening the smoke exhaust channel for smoke exhaust or ventilation. At this time, the photovoltaic module glass plate is tightly attached to the top of the transparent glass plate and rotates synchronously. When encountering rain, snow, or strong sunlight, this invention can control the extension of the electric rod so that the locking block connected to one end of the electric rod can be locked inside the slot opened in the photovoltaic module glass plate for limiting. At this time, when the transparent glass plate is rotated by the drive motor, the movement displacement between the transparent glass plate and the photovoltaic module glass plate is different until the transparent glass plate is in a vertical state and the photovoltaic module glass plate is in a horizontal state and located on top of the transparent glass plate, thus achieving the blocking of rain and snow or the blocking of strong sunlight. In this invention, when the wind cup assembly is in a vertical position, its first meshing gear meshes with the second meshing gear. Wind power drives the wind cup assembly to rotate, which in turn drives the first meshing gear, which in turn drives the second meshing gear. Then, a rotating shaft drives the third meshing gear to rotate, which in turn meshes with the rotating gear ring plate, causing the fan to expel flue gas outwards. This significantly reduces the number of times the servo motor is used, increasing its lifespan. Furthermore, during the rotation of the gear ring plate, the circular limiting groove and ball bearings greatly reduce the friction generated during rotation, not only increasing the lifespan of the gear ring plate but also facilitating faster rotation speed and thus faster flue gas expulsion.

[0016] In summary, this invention employs different opening methods depending on the weather. In cool weather, the transparent glass panel and the photovoltaic module glass panel move as a single unit, with a servo motor controlling the fan to exhaust smoke or exchange air. In hot or rainy / snowy weather, the movement and displacement between the transparent glass panel and the photovoltaic module glass panel differ until the transparent glass panel is vertical and the photovoltaic module glass panel is horizontal and located on top of the transparent glass panel. This achieves the purpose of blocking rain and snow or blocking strong sunlight. At this time, the rotation of the wind cup assembly drives the fan to rotate and exhaust smoke, greatly reducing the number of times the servo motor is used and improving its service life.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0021] Please see Figure 1-7 A smart smoke exhaust skylight based on photovoltaic power generation includes a ground 1 with a convex structure. A smoke exhaust channel 2 is provided below the ground 1, penetrating the top of the ground 1. The top of the smoke exhaust channel 2 is inclined and has a transparent glass plate. A rotating rod is provided at the front and rear ends of the inclined end of the transparent glass plate, which is rotatably connected to a rotating frame 4. The bottom of the rotating frame 4 is fixed to the top of the ground 1. A drive component 5 is also provided at the top end of the ground 1 to drive the transparent glass plate to rotate. A photovoltaic module glass plate 6 is provided at the top of the transparent glass plate. A connecting rail 7 is provided at the front and rear ends of the bottom of the photovoltaic module glass plate 6. A limit mechanism 8 is provided between the connecting rail 7 and the transparent glass plate. A wind cup assembly 9 is provided at one end of the connecting rail 7 and connected to the transparent glass plate. A fan assembly 10 is provided inside the smoke exhaust channel 2 to quickly exhaust the smoke.

[0022] like Figure 1-7 As shown, the drive assembly 5 includes a drive motor 501 mounted on the ground 1. The output end of the drive motor 501 is connected to a first drive gear 502. The front end rotating rod of the transparent glass plate passes through the front end face of the rotating frame 4 and is connected to a second drive gear 503. A transmission chain 504 is provided on the outer wall of the first drive gear 502 and the second drive gear 503. During normal operation, the drive motor 501 drives the first drive gear 502 to rotate, thereby driving the second drive gear 503 to rotate through the transmission chain 504, which in turn drives the transparent glass plate to rotate and open the smoke exhaust channel 2 for smoke exhaust or ventilation. At this time, the photovoltaic module glass plate 6 is tightly attached to the top of the transparent glass plate and rotates synchronously.

[0023] like Figure 1-7 As shown, telescopic rods 11 are installed at the front and rear ends of the recessed part of the ground 1. A universal joint 12 is connected to the top of the telescopic rod 11, and a mounting base 13 is connected to the top of the universal joint 12. An electric rod 14 is installed inside the mounting base 13. When encountering rain, snow, or strong sunlight, the electric rod can be extended so that the locking block connected to one end of the electric rod can be locked inside the slot opened in the photovoltaic module glass panel 6 for limiting. At this time, when the transparent glass panel is rotated by the drive motor 501, the movement displacement between the transparent glass panel and the photovoltaic module glass panel 6 is different until the transparent glass panel is in a vertical state and the photovoltaic module glass panel 6 is in a horizontal state and located on top of the transparent glass panel, thus achieving the blocking of rain and snow or the blocking of strong sunlight.

[0024] like Figure 1-7 As shown, the limiting mechanism 8 includes a groove 801 opened inside the connecting track 7. A slider 802 adapted to the groove 801 is provided inside the groove 801. Fixed rods 803 are provided at the front and rear ends of one end of the transparent glass plate and are rotatably connected to the slider 802. A through hole 804 communicating with the groove 801 is opened at the opposite end of the connecting track 7. When the transparent glass plate rotates, the fixed rods 803 at the front and rear ends of the transparent glass plate rotate inside the slider 802, and the slider 802 slides inside the groove 801. At this time, the photovoltaic module glass plate 6 moves upward as a whole, and drives the telescopic rod 11 to extend until the transparent glass plate is in a vertical state and presses against the photovoltaic module glass plate 6.

[0025] like Figure 1-7 As shown, one end of the fixed rod 803 extends through to the outside of the connecting rail 7 and is welded to a rotating sleeve 15. The inside of the rotating sleeve 15 is rotatably connected to the shaft of the wind cup assembly 9. The bottom of the shaft is connected to the first meshing gear 16. When the transparent glass plate rotates, the fixed rod 803 also rotates, so that when the transparent glass plate is in a vertical state, the wind cup assembly 9 is in a vertical state.

[0026] like Figure 1-7 As shown, the fan assembly 10 includes a fixing plate 101 that is equidistantly fixed to the inner wall of the smoke exhaust channel 2. A motor housing is provided at one end of the fixing plate 101. A servo motor 102 is installed inside the motor housing. The output end of the servo motor 102 is connected to a fan 103 with a rotating shaft. A circular groove 104 is provided on the inner wall of the smoke exhaust channel 2. A toothed ring plate 105 is provided inside the circular groove 104. A connecting plate 106 is installed on the inner side of the toothed ring plate 105 and installed on the outer wall of the blades of the fan 103. A through groove is provided at the front end of the inner wall of the smoke exhaust channel 2. The servo motor 102 can drive the fan 103 to rotate, thereby exhausting the smoke or air inside the smoke exhaust channel 2 to the outside.

[0027] like Figure 1-7As shown, an annular limiting groove 17 is provided at the bottom of the annular groove 104. A ball is provided inside the annular limiting groove 17. The annular limiting groove 17 and the ball greatly reduce the friction generated by the toothed ring plate 105 during rotation. This not only improves the service life of the toothed ring plate 105, but also facilitates the acceleration of the rotation speed of the toothed ring plate 105, thereby accelerating the discharge of flue gas.

[0028] like Figure 1-7 As shown, a rotating shaft 18 fixed to the top of the ground 1 is installed in front of the smoke exhaust channel 2 via a bearing. The top of the rotating shaft 18 is connected to a second meshing gear 19 that meshes with the first meshing gear 16. A third meshing gear 20 that meshes with the gear ring plate 105 is also installed on the outer wall of the rotating shaft 18. When the wind cup assembly 9 is in a vertical state, its first meshing gear 16 is just meshed with the second meshing gear 19. The wind can drive the wind cup assembly 9 to rotate, thereby driving the first meshing gear 16 to rotate, which in turn drives the second meshing gear 19 to rotate. Then, the rotating shaft 18 drives the third meshing gear 20 to rotate, which in turn meshes with the rotating gear ring plate 105 to drive the fan 103 to exhaust the smoke outward.

[0029] like Figure 1-7 As shown, a battery and controller are installed on the top of ground 1, and an alarm is installed on the inner wall of the smoke exhaust duct 2. The battery, controller, and alarm are all electrically connected. The battery stores the energy absorbed by the photovoltaic module glass panel 6, and then provides power to the drive motor 501 and servo motor 102. The controller can control the drive motor 501, servo motor 102, and electric pole 14 to work. Since the battery, controller, and alarm used are all existing technologies, the diagrams are omitted here and will not be described in detail.

[0030] Working principle: During normal operation, the drive motor 501 drives the first drive gear 502 to rotate, which in turn drives the second drive gear 503 to rotate via the transmission chain 504. This, in turn, rotates the transparent glass panel to open the exhaust duct 2 for smoke extraction or ventilation. At this time, the photovoltaic module glass panel 6 is tightly attached to the top of the transparent glass panel and rotates synchronously. The servo motor 102 drives the fan 103 to rotate, thereby expelling the smoke or air inside the exhaust duct 2. When encountering rain, snow, or other adverse weather conditions, the exhaust duct will open. When sunlight is strong, the electric rod can be extended to lock the locking block at one end into the slot of the photovoltaic module glass panel 6 for limiting its position. At this time, when the drive motor 501 rotates the transparent glass panel, the fixing rods 803 at the front and rear ends of the transparent glass panel rotate inside the slider 802, and the slider 802 slides inside the groove 801. This causes the photovoltaic module glass panel 6 to move upwards, extending the telescopic rod 11 until the transparent glass panel is vertical and presses against the photovoltaic module glass panel. 6. As the transparent glass plate rotates, the fixing rod 803 also rotates, causing the transparent glass plate to be in a vertical state. When this state is achieved, the wind cup assembly 9 is also in a vertical state, and its first meshing gear 16 meshes with the second meshing gear 19. The wind force drives the wind cup assembly 9 to rotate, which in turn drives the first meshing gear 16, which in turn drives the second meshing gear 19. Then, the rotating shaft 18 drives the third meshing gear 20 to rotate, which in turn meshes with the rotating gear ring plate 105, causing the fan 103 to expel the flue gas outwards. This significantly reduces the servo motor... The increased usage frequency improves the service life of the servo motor. Furthermore, during the rotation of the gear ring plate 105, the circular limiting groove 17 and the ball bearings significantly reduce the friction generated during rotation. This not only extends the service life of the gear ring plate 105 but also facilitates faster rotation speed, thus accelerating the exhaust of smoke. In the event of a fire, the internal alarm in the smoke exhaust channel 2 activates, and the independent power supply inside the battery powers the servo motor 102, driving the fan to rotate and quickly exhaust the smoke.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
