[0017] The following is a more detailed description of a large-capacity filling lifting system of the utility model in conjunction with a schematic diagram, which shows a preferred embodiment of the utility model. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0018] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0019] like Figure 1-Figure 2 The wind pendulum structure shown comprises three ventilation pipes 1, a motor 5 arranged on the three ventilation pipes 1, a first rotating device and a second rotating device passing through the three ventilation pipes 1,

[0020] The motor 5 is connected to the first rotating device to drive the first rotating device to rotate;

[0021] The second rotating device is engaged with the first rotating device, and can switch the air volume of different air outlets of the three ventilation pipes 1 under the drive of the first rotating device.

[0022] Specifically, the three ventilation ducts 1 include an air inlet 9, a first air outlet 10 and a second air outlet 11, so that air enters from the air inlet 9 and exits from the first air outlet 10 and the second air outlet 11; the first rotating device is close to the air inlet 9, and the second rotating device is located in the middle position between the first air outlet 10 and the second air outlet 11, and corresponds to the first rotating device.

[0023] In a specific embodiment, the first rotating device includes a first rotating shaft 2, a driving gear 7 and a bearing seat 4; the driving gear 7 is sleeved on the first rotating shaft 2, one end of the first rotating shaft 2 passes through the three ventilation pipes 1 to be connected to the driving shaft of the motor 5, and the other end passes through the three ventilation pipes 1 to be rotatably connected to the bearing seat 4, and then the motor 5 drives the driving gear 7 to rotate.

[0024] The second rotating device includes a second rotating shaft 3, a driven gear 8, a damper blade 6 and a bearing seat 4; the damper blade 6 is mounted on the second rotating shaft 3, the driven gear 8 is mounted on the damper blade 6, and both ends of the second rotating shaft 3 pass through the three ventilation pipes 1 and are respectively rotatably connected to the corresponding bearing seats 4. The damper blade 6 can be mounted on the second rotating shaft 3 by bolts, and the driven gear 8 can be welded to the damper blade 6.

[0025] In this embodiment, the driving gear 7 is a small gear with a common structure, the driven gear 8 is a large gear with a fan-shaped structure, the gears of the driving gear 7 and the driven gear 8 are meshed with each other, and then the driven gear 8 is driven by the driving gear 7 to operate, thereby driving the air valve blade 6 to swing back and forth to achieve air supply.

[0026] Furthermore, the motor 5 is a reduction motor. It should be noted that the reduction motor can convert the high-speed rotation of the motor into a lower speed and higher torque output. This characteristic makes the reduction motor very suitable for reciprocating motion that requires precise control of speed and position.

[0027] As a preferred embodiment, the device uses the motor 5 to drive the driving gear 7 to operate, and the driving gear 7 drives the driven gear 8 to operate, thereby driving the damper blade 6 to rotate around the second rotating shaft 3. The wind enters the three ventilation pipes 1 from the air inlet 9. When the damper blade 6 approaches the first air outlet 10 and swings from the first outlet 10 to the second air outlet 11, most of the wind entering the device from the air inlet 9 is diverted and discharged from the second air outlet 11. As the damper blade 6 swings toward the second air outlet 11, the air volume of the first air outlet 10 gradually increases, and the air volume of the second air outlet 11 gradually decreases, until most of the wind entering the device from the air inlet 9 is discharged from the first air outlet 10, and the reciprocating motion is repeated. The device uses the characteristics of the reduction motor to make the damper blade 6 swing stably and realize linear control of the air volume, that is, while the air volume of the second air outlet 11 gradually increases, the air volume of the first air outlet 10 gradually decreases, so that the air supply is more uniform and more natural.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
