Abstract
Description
Technical Field
[0001] This utility model relates to the field of dampers, specifically a damper structure. Background Technology
[0002] Air dampers are an important component of ventilation systems, mainly used to adjust and control parameters such as airflow direction, flow rate, and air pressure to meet the ventilation needs of different working scenarios. They are widely used in many fields such as mines, tunnels, and building ventilation. Made primarily of steel, they have high strength and durability, can withstand greater pressure and impact, and are suitable for occasions with high ventilation pressure and harsh operating environments.
[0003] However, most traditional damper structures are manually adjustable. Manually adjusting dampers requires personnel to be on-site to operate them. From the time a change in ventilation demand is detected to the time personnel arrive at the damper position and complete the adjustment, it often takes a long time. Furthermore, manually adjusting dampers usually requires the use of tools (such as wrenches, pry bars, etc.) to turn the damper's adjustment mechanism, making the operation process cumbersome. Moreover, during the adjustment process, it is necessary to constantly observe the ventilation effect and repeatedly adjust the damper opening until the ideal ventilation state is achieved, which further reduces the operating efficiency. Utility Model Content

Manual adjustment of dampers requires personnel to be on-site to operate, which often takes a long time from the discovery of changes in ventilation demand to personnel arriving at the damper position and completing the adjustment. This utility model proposes a damper structure.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0023] This application discloses a damper structure. (Refer to...) Figure 1 and Figure 2A damper structure includes a duct 1, with a first flange 2 fixedly connected to one end of the duct 1. A first support plate 3, L-shaped, is provided on one side of the first flange 2. A first fixing bolt 4 is fixedly connected to the inner cavity of the first flange 2 and the inner cavity of the first support plate 3. A junction box 5 is fixedly connected to one side of the first support plate 3, and an actuator 6 is fixedly installed on one side of the first support plate 3. A drive shaft 7 is fixedly connected to the output end of the actuator 6. A connecting shaft 8 is fixedly connected to one end of the drive shaft 7, and the other end of the connecting shaft 8 is rotatably connected to the inner cavity of the duct 1. A rotating plate 9 is fixedly connected to the surface of the connecting shaft 8 and is located in the inner cavity of the duct 1. In this damper structure, the duct 1 is connected to the air outlet duct of the ventilation system through the first flange 2, and the L-shaped first support plate 3 is connected to the air outlet duct of the ventilation system through the first flange 2. The first fixing bolt 4 is fixedly connected to the first flange 2. The first support plate 3 can install and support the equipment that drives the rotating plate 9 to rotate. The junction box 5 can be of model 20010-83-0V. The junction box 5 is an important part of the electrical wiring system. It is mainly used to protect and connect wires. At the joint of the wire, the junction box 5 can be used as a transition device to connect the wire conduit to the junction box 5. The wires in the conduit are connected in the junction box 5. The wires in the junction box 5 can be connected to the actuator 6. The actuator 6 can be of model 1H6030002. It drives the transmission shaft 7 to output power through the internal motor. The transmission shaft 7 and the connecting shaft 8 are fixedly connected. The connecting shaft 8 can rotate along the inner cavity of the air duct 1. While the connecting shaft 8 rotates, the rotating plate 9 is automatically opened and closed for adjustment.
[0024] Reference Figure 3 One end of the duct 1 is fixedly connected to a second flange 10, and the inner wall of the second flange 10 is fixedly connected to a mounting frame 11. The inner wall of the mounting frame 11 is fixedly connected to a filter screen 12. The second flange 10 plays a major connecting role to the mounting frame 11. The filter screen 12 in the mounting frame 11 can block external dust and impurities, and minimize the entry of dust and impurities into the duct 1 to affect the ventilation effect.
[0025] Reference Figure 3 and Figure 4A second support plate 13 is provided on one side of the second flange 10. The second support plate 13 is L-shaped. A second fixing bolt 14 is fixedly connected to the inner cavity of the second flange 10 and the inner cavity of the second support plate 13. A guide sleeve 15 is fixedly connected to one side of the second support plate 13. A bearing 16 is fixedly connected to the inner cavity of the guide sleeve 15. A rotating rod 17 is fixedly connected to the inner wall of the inner ring of the bearing 16. A connecting rod 18 is fixedly connected to the surface of the rotating rod 17. There are multiple connecting rods 18. A wind cup 19 is fixedly connected to the other end of each connecting rod 18. A cam 20 is fixedly connected to one end of the rotating rod 17. The surface of the cam 20 abuts against one side of the mounting frame 11. Through the cam 20, the second support plate 13 can be fixedly connected to the second flange 10 via the second fixing bolt 14. The wind cup 19 can be connected to the rotating rod 17 via the connecting rod 18. When the concave surface of the wind cup 19 faces the wind, it is pushed by the wind force, and when the convex surface faces the wind, the wind resistance is small, forming a continuous rotational torque. As a result, the rotating rod 17 rotates along the guide sleeve 15 via the bearing 16. When the rotating rod 17 rotates, it drives the cam 20 at one end to rotate. When the cam 20 rotates, the protruding part intermittently hits the mounting frame 11, causing the mounting frame 11 to vibrate. When the mounting frame 11 vibrates, it shakes off the filtered dust and impurities, ensuring the filtration efficiency and ventilation of the filter screen 12.
[0026] Reference Figure 5 An installation pipe 21 is fixedly connected to the surface of the air duct 1. One end of the installation pipe 21 is fixedly connected to a collection box 22. Through the collection box 22, the inner wall of the installation pipe 21 is fixedly connected to the inner wall of the air duct 1, and the inner wall of the collection box 22 is connected to the inner wall of the installation pipe 21, so that the dust and impurities shaken off are collected in the collection box 22 for easy centralized treatment later.
[0027] Working principle: The duct 1 is connected to the air outlet duct of the ventilation system through the first flange 2. The L-shaped first support plate 3 is fixedly connected to the first flange 2 through the first fixing bolt 4. The first support plate 3 can install and support the equipment that drives the rotating plate 9 to rotate. The junction box 5 can be of model 20010-83-0V. The junction box 5 is an important part of the electrical wiring system, mainly used to protect and connect wires. At the joint of the wires, the junction box 5 can act as a transition device to connect the conduit to the junction box 5. The wires in the conduit are connected in the junction box 5. The wires in the junction box 5 can be connected to the actuator 6. The actuator 6 can be of model 1H6030002. It drives the drive shaft 7 to output power through the internal motor. The drive shaft 7 and the connecting shaft 8 are fixedly connected. The connecting shaft 8 can rotate along the inner cavity of the duct 1. While the connecting shaft 8 rotates, the rotating plate 9 is automatically opened and closed for adjustment. The second flange 10 plays a major connecting role to the mounting frame 11. The filter screen 12 in frame 11 can block external dust and impurities, minimizing their entry into the duct 1 and affecting ventilation. The second support plate 13 can be fixedly connected to the second flange 10 via the second fixing bolt 14. The wind cup 19 can be connected to the rotating rod 17 via the connecting rod 18. When the concave surface of the wind cup 19 faces the wind, it is pushed by the wind force, while the convex surface faces the wind with less resistance, forming a continuous rotational torque. As a result, the rotating rod 17 rotates along the guide sleeve 15 via the bearing 16. While the rotating rod 17 rotates, it drives the cam 20 at one end to rotate. As the cam 20 rotates, its protruding part intermittently strikes the mounting frame 11, causing the mounting frame 11 to vibrate. The vibration of the mounting frame 11 shakes off the filtered dust and impurities, ensuring the filtration efficiency and ventilation of the filter screen 12. The inner wall of the mounting pipe 21 is fixedly connected to the inner wall of the duct 1, and the inner wall of the collection box 22 is connected to the inner wall of the mounting pipe 21, so that the shaken-off dust and impurities are collected in the collection box 22 for easy centralized processing later.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
