[0033] Embodiment:
[0034] Figure 1 This is a schematic installation structure diagram of the rotary vane damper and plug valve double-driving device of the present utility model. Figure 4 This is a schematic side view structure diagram of the plug valve double-driving device of the rotary vane damper and plug valve double-driving device of the present utility model. Figure 5 This is a schematic front view structure diagram of the plug valve double-driving device of the rotary vane damper and plug valve double-driving device of the present utility model. As Figure 1 、 Figure 4 andFigure 5 As shown in Figure 5 , the rotary vane damper and slide damper dual-drive device is used for damper 1. Damper 1 includes a door panel 11 and an operating mechanism 12. The second ends of the operating mechanism 12 are symmetrically connected to both ends on the opening side of damper 1. The rotary vane damper and slide damper dual-drive device includes a first actuator 2 and a second actuator 21. Those skilled in the art know that damper 1 in this embodiment can be a rotary vane damper 1 or a slide damper 1. The first actuator 2 and the second actuator 21 have the same structure, so the first actuator 2 will be used as an example for subsequent description.
[0035] Figure 2 It is a front view structural schematic diagram of the actuator in the rotary vane damper and slide damper dual-drive device of the present utility model. Figure 3 It is a side view structural schematic diagram of the actuator in the rotary vane damper and slide damper dual-drive device of the present utility model. As Figures 1 to 3 shown in Figures 1 to 3 , the first actuator 2 and the second actuator 21 are symmetrically arranged at both ends on the opening side of damper 1. The first actuator 2 and the second actuator 21 include a driving shaft 3 and an operating mechanism 4. The first end of the driving shaft 3 is telescopically connected to the output end of the first actuator 2. The second end surface has an annular groove 5, and the position of the second end corresponds to the operating mechanism 12. Exemplarily, the first actuator 2 further includes a first bracket 6. The driving shaft 3 passes through the first bracket 6, and a telescopic first clutch gear 7 is provided at the second end of the driving shaft 3. The annular groove 5 is located on the surface of the first end of the first clutch gear 7. The diameter of the first clutch gear 7 is larger than the diameter of the driving shaft 3. A driven shaft 13 is provided at the first end of the operating mechanism 12, and a second clutch gear 14 is provided at the first end of the driven shaft 13. The tooth parts of the first clutch gear 7 and the second clutch gear 14 are meshed to prevent the driving shaft 3 from disengaging from the operating mechanism 12 during operation. The operating mechanism 4 has a rotatable rotating shaft 41, and the rotating shaft 41 is meshed with the annular groove 5.
[0036] Among them, the first actuator 2 and the second actuator 21 drive the driving shaft 3 to rotate. The rotating shaft 41 rotates to drive the driving shaft 3 to move forward or backward in the horizontal direction, so that the second end of the driving shaft 3 meshes with or disengages from the first end of the operating mechanism 12. After meshing, the driving shaft 3 drives the operating mechanism 12 to rotate to open or close damper 1. Exemplarily, a telescopic coupling 9 is provided at the first end of the driving shaft 3. The telescopic coupling 9 connects the output end of the first actuator 2, and the telescopic coupling 9 realizes the telescopic connection between the first clutch gear 7 and the driving shaft 3.
[0037] As Figure 2 shown in Figure 2 , further, the first actuator 2 further includes an elastic member 8. The elastic member 8 is sleeved on the driving shaft 3. The second end of the elastic member 8 abuts against the first end of the first clutch gear 7, and the first end of the elastic member 8 abuts against the first bracket 6. The elastic member 8 can isolate and relieve the vibration and impact when the driving shaft 3 rotates.
[0038] As Figures 2 to 3As shown, further, the operating mechanism 4 further includes a second bracket 42 and a driving component. There are two second brackets 42, symmetrically arranged outside the first clutch gear 7. The rotating shaft 41 is rotatably mounted within the second bracket 42, and the driving component is connected to the outside of the rotating shaft 41.
[0039] As Figures 2 to 3 shown, exemplarily, the driving component is a handle 43. The handle 43 is located on the surface of the second bracket 42. The connection part of the handle 43 passes through the surface of the second bracket 42 and is connected to the front end shaft head of the rotating shaft 41. Specifically, the rotation direction of the handle 43 is the same as that of the output shaft of the second motor. For example, clockwise is for closing and counterclockwise is for opening. It has two driving methods, electric control and manual control. When the power system fails, the operating mechanism 4 can be manually controlled. Of course, in other embodiments of the present invention, the driving component can be a second motor (not shown in the figure), and the output end of the second motor is connected to the rear end shaft head of the rotating shaft 41.
[0040] As Figure 2 shown, further, two pin rods 44 are provided on the second bracket 42. The two pin rods 44 are screwed to the second bracket 42. Rotating the handle 43 downward drives the rotating shaft 41 to the first state, and the driving shaft 3 meshes with the operating mechanism 12. The pin rods 44 are located at the upper end of the handle 43, preventing it from moving to the second state. Rotating the handle 43 upward drives the rotating shaft 41 to the second state, and the driving shaft 3 is separated from the operating mechanism 12. The pin rods 44 are located at the lower end of the handle 43, preventing it from moving to the first state.
[0041] As Figure 2 shown, further, the first actuator 2 further includes a first motor 22 and a speed reducer 23. The output end of the first motor 22 is connected to the speed reducer 23, and the driving shaft 3 is connected to the output end of the speed reducer 23. For example, the first motor 22 uses a special valve three-phase asynchronous motor.
[0042] As Figures 1 to 5 shown, further, the rotary vane damper and the louver damper dual-driving device further includes a base 10. The first bracket 6 and the second bracket 42 are fixed on the base 10, and the base 10 is cast on the ground to improve the stability of the actuator.
[0043] During the operation of this embodiment:
[0044] The first actuator 2 fails, the first motor 22 of the first actuator 2 is turned off, the driving shaft 3 of the first actuator 2 stops rotating, the second motor is operated or the handle 43 is pulled counterclockwise, the output end of the second motor or the handle 43 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the driving shaft 3 to retreat towards the first actuator 2 through the annular groove 5, so that the first clutch gear 7 of the first actuator 2 is disengaged from the second clutch gear 14 of the operating mechanism 12. The second motor of the second actuator 21 or the handle 43 of the second actuator 21 is pulled clockwise, the output end of the second motor or the handle 43 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the driving shaft 3 to advance towards the second clutch gear 14 through the annular groove 5, so that the first clutch gear 7 of the second actuator 21 is engaged with the second clutch gear 14 of the operating mechanism 12. Then the first motor 22 of the second actuator 21 is started, the output end of the first motor 22 drives the driving shaft 3 of the second actuator 21 to rotate, and the driving shaft 3 drives the operating mechanism 12 of the second actuator 21 to rotate, so that the air damper 1 is opened or closed. Replacing the first actuator 2 with the second actuator 21 avoids the potential safety hazard problem that the first actuator 2 cannot be repaired immediately when it fails, ensures that the air damper can work normally, and improves the working stability of the double-drive device for the rotary vane air damper and the flap air damper.
[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0046] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
