[0031] Figure 1 It is a schematic structure diagram of the air damper device of an embodiment of the present invention. As Figure 1 shown and referring to Figures 2 to 5 , the embodiment of the present invention provides an air damper device 20 for an anti - gathering system, which includes a control box 21, two rollers 22, a control belt 23, a driving internal gear ring 24, a rotating frame 25, a plurality of driving gears 26 and an elastic device 27. Part or all of the side wall of the control box 21 is an air supply plate, and a plurality of air supply outlets 28 are arranged at intervals along its length direction on the air supply plate. The control box 21 also has an air supply inlet 29. The two rollers 22 are arranged in parallel and are arranged inside the control box 21. The control belt 23 is connected end to end to form a ring, and a communication port 30 is arranged on the control belt 23. The control belt 23 is installed on the two rollers 22, and the control belt 23 is attached to the air supply plate to move around the two rollers 22 driven by the rollers 22, so that the communication port 30 is aligned with an air supply outlet 28. The driving internal gear ring 24 is arranged in the control box 21 so as to be unidirectionally rotatable around a first direction, and is in transmission connection with the rollers 22 to drive the rollers 22 to rotate. The rotating frame 25 is rotatably arranged in the control box 21 around a second direction opposite to the first direction, and the rotation axis of the rotating frame 25 coincides with the rotation axis of the driving internal gear ring 24. A plurality of driving gears 26 are arranged at intervals along the circumferential direction of the driving internal gear ring 24 inside the driving internal gear ring 24, and are meshed with the driving internal gear ring 24. Each driving gear 26 is rotatably installed on the rotating frame 25, and an eccentric connecting column is arranged on each driving gear 26. The elastic device 27 is arranged between the eccentric connecting column and the rotating frame 25 to urge the eccentric connecting column to move outwards.

[0032] In this embodiment, when the rotating frame 25 rotates, it will drive a plurality of driving gears 26 to revolve. Under the action of the driving internal gear ring 24, the plurality of driving gears 26 roll on the driving internal gear ring 24, that is, the driving gears 26 rotate self - identically. At the same time, the elastic device 27 will continue to be squeezed and store energy. As the driving gears 26 rotate self - identically, the extrusion force on the elastic device 27 gradually reaches the maximum. At this time, the rotation of the driving gears 26 makes the distance between the eccentric connecting column and the center of the rotating frame 25 the shortest. Then the distance between the eccentric connecting column and the center of the rotating frame 25 will become larger, and the elastic device 27 will release the stored energy, prompting the distance between the eccentric connecting column and the center of the rotating frame 25 to become larger. However, under the limiting action of the rotating frame 25, the driving gears 26 will act on the driving internal gear ring 24 in turn, causing the driving internal gear ring 24 to rotate. The driving internal gear ring 24 drives the control belt 23 to move, aligning the communication port 30 with another air supply outlet 28, and supplying gas to different positions in the collective defense space.

[0033] The special air damper device 20 of the embodiment of the present invention can make clean air be sequentially delivered to multiple places in the collective defense space through a plurality of air supply outlets 28, enabling the clean air to fill the collective defense space as quickly as possible and be distributed as evenly as possible in the collective defense space, thereby ensuring the uniformity of the air quality in the collective defense space and further ensuring the overall environmental quality in the collective defense space. Moreover, the air damper device 20 does not require the rotation motor to stop, can ensure the consistency of the opening time of each air supply outlet 28, has high control precision, ensures environmental quality, can prevent problems such as inaccurate control and easy damage to the motor caused by frequent start - stop of the motor, can also significantly reduce the no - load time of the motor, making the motor basically without no - load, reducing the air damper switching time, and having high switching efficiency; furthermore, it can also reduce the impact on the air purification system and prevent a large amount of gas from accumulating in the air purification system.

[0034] In some embodiments of the present invention, the elastic device 27 includes a plurality of springs. Each spring extends along the radial direction of the rotating frame 25, and one end of each spring is connected to the rotating frame 25, and the other end is connected to an eccentric connecting column, and the spring is always in a compressed state. Further, the air damper device 20 preferably uses a constant - speed motor 31. The constant - speed motor 31 drives the rotating frame 25 to rotate at a constant speed through a transmission mechanism. The driving internal gear ring 24 is coaxially arranged and fixedly connected with a roller 22. The roller 22 is installed in the control box 21 through an overrunning clutch, so that the roller 22 and the driving internal gear ring 24 rotate unidirectionally around the first direction. The rotation direction of the rotating frame 25 can be controlled by the constant - speed motor 31 or can be controlled by setting an overrunning clutch or other one - way transmission mechanisms.

[0035] Furthermore, the constant-speed motor 31 is arranged inside the control belt 23, and the transmission mechanism is a belt transmission mechanism 32. The arrangement position of the constant-speed motor 31 is beneficial to the cooling of the constant-speed motor 31, that is, using clean air to cool the constant-speed motor 31. When the clean air needs to be heated, the heat of the constant-temperature motor can be fully utilized. At the same time, the setting of the constant-temperature motor will not affect the flow of clean air. The constant-speed motor 31 is arranged inside the control box 21, which is also beneficial to the noise reduction of the whole device.

[0036] In some embodiments of the present invention, the cross-section of the side wall of the control box 21 is circular, the entire side wall of the control box 21 is a air supply plate, a retaining cylinder is arranged inside the air supply plate, the control belt 23 is clamped between the air supply plate and the retaining cylinder, and the air supply inlet 29 is arranged on the top wall of the control box 21. By arranging an arc-shaped or circular air supply plate and setting the air supply inlet 29 on the top wall of the control box 21, it is beneficial for the gas to be transmitted to each air supply outlet 28. The arc-shaped or circular air supply plate, the retaining cylinder and the control belt 23 can all guide the air supply, so as to facilitate the air supply to each air supply outlet 28.

[0037] In order to further improve the air supply efficiency, the air supply outlets 28 are evenly distributed along the circumferential direction of the control box 21, and there are two communication ports 30, which are evenly distributed along the circumferential direction of the control belt 23. Two symmetrically arranged communication ports 30 are used for control at the same time, cooperating with two groups of symmetrically arranged clean air inlets, to improve the control efficiency and ensure the environmental quality in the collective defense space.

[0038] In some embodiments of the present invention, as Figure 5 shown, a linkage device is arranged between every two adjacent driving gears 26 to make the multiple driving gears 26 move synchronously. For example, the linkage device includes a plurality of linkage rods 33. Both ends of each linkage rod 33 have strip-shaped chutes 34, and the eccentric connecting columns on every two adjacent driving gears 26 are respectively inserted into the two strip-shaped chutes 34 of a linkage rod 33, and each linkage rod 33 is perpendicular to the radial direction of the rotating frame 25 and is slidably installed on the rotating frame 25 along the radial direction of the rotating frame 25. By arranging the strip-shaped chutes 34, the driving gears 26 can rotate synchronously, and at the same time, there will be no movement interference between the driving gears 26.

[0039] Figure 6 is a schematic diagram of the collective defense system according to an embodiment of the present invention, as Figure 6As shown in the figure, the embodiment of the present invention also provides a collection and prevention system. Generally, the collection and prevention system includes a collection and prevention space 10, an air purification system 11 for delivering clean air into the collection and prevention space 10, and a pressure relief valve for discharging the gas in the collection and prevention space 10. The air purification system 11 inputs clean air into the collection and prevention space 10, and the pressure relief valve discharges clean air into the external space, which can keep a positive pressure environment in the collection and prevention space 10 and prevent harmful gases from the outside from automatically penetrating into the collection and prevention space 10. The harmful gas can be a toxic gas, etc. In particular, the collection and prevention system in the embodiment of the present invention further includes the air door device 20 in any of the above embodiments. The collection and prevention space 10 has a plurality of clean air inlets. The air door device 20 is arranged between the air purification system and the collection and prevention space 10, and the air supply inlet 29 communicates with the air purification system. Each air supply outlet 28 communicates with the clean air inlet through the air inlet pipe 12. Preferably, the plurality of clean air inlets are arranged on both sides of the upper part of the collection and prevention space, and the clean air inlets on each side are evenly distributed along the length direction of the collection and prevention space.

[0040] In some embodiments of the present invention, the collection and prevention system further includes an air compression storage device, an air treatment device, a first control valve, and a second control valve. The outlet of the pressure relief valve communicates with a pre-storage chamber. The first control valve is arranged between the air treatment device and the pre-storage chamber and is configured to controllably allow the gas in the pre-storage chamber to enter the air treatment device or flow into the external environment of the collection and prevention space 10. The air treatment device is configured to remove carbon dioxide from the received air. The air compression storage device receives the gas processed by the air treatment device and compresses and stores it. The second control valve is arranged between the air compression storage device and the collection and prevention space 10 to controllably deliver the stored gas into the collection and prevention space 10. The operation of the second control valve can be controlled by detecting the oxygen concentration in the collection and prevention space 10. The outlet of the second control valve can be respectively connected to an air inlet pipe to deliver gas into the collection and prevention space 10 through the clean air inlet.

[0041] In the collection and prevention system of the embodiment of the present invention, due to the air treatment device and the air compression storage device, the clean gas flowing out through pressure relief can be saved again and then returned to the collection and prevention space 10 in a cycle. According to the gas in the collection and prevention space 10, such as the oxygen concentration, etc., clean gas can be alternately delivered into the collection and prevention space 10, improving the service life of the collection and prevention system. It can also provide clean gas to the collection and prevention space 10 alone when the external environment is extremely poor and the efficiency of the air purification system 11 is extremely low, ensuring the environmental safety in the collection and prevention space 10. At the same time, carbon dioxide is removed during storage, improving the storage capacity and storage efficiency.

[0042] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the disclosed content of the present invention without departing from the spirit and scope of the present invention.
