[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a safe and energy-saving hybrid ventilation device for industrial plants, such as... Figure 1-5 As shown, the industrial plant's safe and energy-saving hybrid ventilation device includes a ventilation duct body 1, a rotating base 2 fixedly installed at the lower end of the ventilation duct body 1, the rotating base 2 fixedly installed on the plant, a fan cover 3 fixedly installed at the lower end of the rotating base 2, a ventilation fan 4 fixedly installed inside the fan cover 3, ventilation blades 5 fixedly installed on the output shaft of the ventilation fan 4, a closing component is provided on the upper left side of the ventilation duct body 1, and adjustment components are provided on the ventilation duct body 1 and the rotating base 2.

[0025] During use, when the ventilation device needs to be activated, the ventilation fan 4 is started by connecting an external power source. The output shaft of the ventilation fan 4 drives the ventilation blades 5 to rotate. At this time, the ventilation blades 5 generate airflow, which is drawn in through the ventilation duct body 1, thus achieving ventilation of the factory. By adjusting the components, the ventilation duct body 1 is rotated, which in turn drives the ventilation blades 5 to rotate. At this time, the direction of the air intake of the ventilation blades 5 changes, thereby changing the amount of ventilation. When natural ventilation is needed, the ventilation duct body 1 is opened by closing the components. Then, according to the difference in air pressure and thermal pressure inside and outside the factory, the air inside and outside the factory will flow under the action of the pressure difference, thereby achieving natural ventilation of the factory.

[0026] Protective covers 6 are fixedly installed on both the upper and lower sides of the fan cover 3. The two sets of protective covers 6 are located on the upper and lower sides of the ventilation fan 4 and the ventilation blades 5.

[0027] The protective cover 6 protects the upper and lower ends of the fan cover 3, preventing damage caused by collisions during use and improving the protective effect of the fan cover 3.

[0028] The closing assembly includes an air vent frame 7, which is fixedly installed at the left end of the ventilation duct body 1. A first drive motor 8 is fixedly installed at the upper end of the air vent frame 7, and a first rotating shaft 9 is provided at the lower end of the first drive motor 8. A first transmission link 10 is installed at the lower end of the first rotating shaft 9. Multiple sets of second rotating shafts 11 are circumferentially installed on the air vent frame 7. The lower end of the first rotating shaft 9 is connected to the second rotating shaft 11. Multiple sets of air guide vanes 12 are rotatably installed inside the air vent frame 7. A second transmission link 13 is fixedly installed on each of the multiple sets of second rotating shafts 11. A hinge rod 14 is rotatably installed between the second rotating shafts 11 and the multiple sets of second transmission links 13.

[0029] When the ventilation volume needs to be adjusted, the first drive motor 8 drives the first rotating shaft 9 to rotate, and the first rotating shaft 9 drives the first transmission link 10 to move. When the first transmission link 10 moves, it drives the first transmission link 10, multiple sets of second rotating shafts 11, multiple sets of second transmission links 13 and multiple sets of hinged rods 14 to rotate, thereby changing the included angle between multiple sets of guide vanes 12, thus adjusting the ventilation volume. This achieves precise control of the ventilation volume and improves the practicality of the ventilation device.

[0030] The adjustment assembly includes a wind direction sensor 15, which is rotatably mounted on the upper side of the ventilation duct body 1. An impeller 16 is mounted on the upper end of the wind direction sensor 15, and a guide vane 17 is provided in the middle of the upper end of the wind direction sensor 15. A second drive motor 18 is installed at the connection between the lower end of the ventilation duct body 1 and the rotating base 2. A drive gear 19 is fixedly mounted on the output shaft of the second drive motor 18. A gear ring groove 20 is opened at the upper end of the rotating base 2, and the drive gear 19 meshes with the inner wall of the gear ring groove 20.

[0031] Based on the airflow direction, the rotating impeller 16 drives the wind direction sensor 15 to rotate. As the wind direction sensor 15 rotates, it detects the airflow. The output shaft of the second drive motor 18 drives the drive gear 19 to rotate on the inner wall of the gear ring groove 20, which in turn drives the ventilation duct body 1 to rotate. At this time, the ventilation duct body 1 drives the air outlet frame 7 to rotate, thereby adjusting the direction of the air inlet of the air outlet frame 7, thus changing the amount of ventilation and improving the practicality of the ventilation device.

[0032] The multiple sets of air guide blades 12 are made of aluminum alloy, and the surface of the multiple sets of air guide blades 12 is anodized.

[0033] By using aluminum alloy to manufacture the multiple sets of air guide blades 12, the corrosion resistance and strength of the multiple sets of air guide blades 12 are improved, ensuring that the multiple sets of air guide blades 12 will not deform or be damaged during long-term use, thus extending the service life of the multiple sets of air guide blades 12. The anodizing treatment increases the surface hardness of the multiple sets of air guide blades 12, improves the wear resistance of the multiple sets of air guide blades 12, avoids scratches and wear during use, and ensures the aesthetics of the multiple sets of air guide blades 12.

[0034] The inner walls of both the ventilation duct body 1 and the rotating base 2 are covered with sound insulation cotton layers, and the thickness of the sound insulation cotton layers on the inner walls of the ventilation duct body 1 and the rotating base 2 is 3-5mm.

[0035] By applying a layer of sound-absorbing cotton, the noise generated by the ventilation system during operation is reduced, avoiding the impact of noise on workers in the factory. At the same time, the noise reduction effect of the ventilation system is improved, making the ventilation system more stable and reliable during operation.

[0036] Working Principle: In operation, firstly, by starting the ventilation fan 4, the output shaft of the fan 4 drives the ventilation blades 5 to rotate. The ventilation blades 5 generate airflow, which draws fresh air into the factory through the main body of the ventilation duct 1, achieving ventilation. The impeller 16 detects the airflow direction and drives the wind direction sensor 15 to rotate. The wind direction sensor 15 is connected to the second drive motor 18 via a data cable. As the wind direction sensor 15 rotates, the output shaft of the second drive motor 18 drives the drive gear 19 to mesh and rotate within the gear ring groove 20, thereby causing the entire ventilation duct body 1 to rotate. The rotation is adjusted on the base 2, at which time the direction of the air intake of the main body 1 of the ventilation duct changes. When it is necessary to adjust the ventilation volume or when natural ventilation is needed, the first drive motor 8 drives the first rotating shaft 9 to rotate. The first rotating shaft 9 drives the first transmission link 10 to move. When the first transmission link 10 moves, it drives the first transmission link 10, multiple sets of second rotating shafts 11, multiple sets of second transmission links 13 and multiple sets of hinge rods 14 to rotate, thereby changing the included angle between multiple sets of guide vanes 12, thereby adjusting the ventilation volume. This achieves precise control of the ventilation volume and improves the practicality of the ventilation device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
