[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example 1: As Figures 1-4As shown, this embodiment provides a duct cleaning device, including a moving mechanism 1, a lifting mechanism 2, a drive motor 3, and a cleaning actuator. The moving mechanism 1 is used to move inside the duct; the lifting mechanism 2 includes a lifting platform 21 and a lifting driver, the lower part of the lifting platform 21 is connected to the moving mechanism 1 through the lifting driver; the lifting driver is used to drive the lifting platform 21 to rise and fall; the drive motor 3 is mounted on the lifting platform 21; the cleaning actuator is fixedly connected to the motor shaft of the drive motor 3, and the drive motor 3 is used to drive the cleaning actuator to rotate to clean the inside of the duct.

[0038] With the above setup, the moving mechanism 1 moves inside the duct, driving the cleaning actuator to clean the inner wall of the duct. The drive motor 3 drives the cleaning actuator to rotate, improving the cleaning effect and resulting in a cleaner finish. The lifting mechanism 2 drives the cleaning actuator to rise and fall, cleaning the upper inner wall of the duct for a more comprehensive cleaning. It can also clean ducts with inconsistent diameters, making it suitable for various duct sizes. The system features automated operation, high efficiency, and thorough cleaning.

[0039] In this embodiment of the duct internal cleaning device, the cleaning execution structure includes a connector 4, a first swing arm 41, and a second swing arm 42. The connector 4 is coaxially and fixedly connected to the motor shaft of the drive motor 3. One end of the first swing arm 41 is hinged to the connector 4 via a rotating shaft, and the other end of the first swing arm 41 is hinged to a first brush 43. One end of the second swing arm 42 is hinged to the connector 4 via a rotating shaft, and the other end of the second swing arm 42 is connected to a second brush 44. The rotation axes of the first swing arm 41 and the second swing arm 42 on the connector 4 coincide. The first brush 43 and the second brush 44 are connected by a drive telescopic assembly 5, which is used to drive the first brush 43 and the second brush 44 to move to adjust the distance between them.

[0040] With the above settings, the telescopic component 5 drives the first swing arm 41 and the second swing arm 42 to unfold, thereby causing the first brush 43 and the second brush 44 to move away, which can clean ducts with larger diameters. The telescopic component 5 drives the first swing arm 41 and the second swing arm 42 to retract, thereby causing the first brush 43 and the second brush 44 to move closer, which can clean ducts with smaller diameters. The structure is simple and adaptable to various ducts. It realizes the automatic opening and closing of the first brush 43 and the second brush 44, thereby realizing the cleaning operation of the inner wall of the round pipe during the diameter change process.

[0041] In this embodiment of the duct internal cleaning device, the drive telescopic component 5 is a drive telescopic rod, one end of which is connected to the first brush 43, and the other end of which is connected to the second brush 44. This configuration is simple in structure and low in cost.

[0042] In one embodiment of the duct internal cleaning device, the driving telescopic rod is a hydraulic rod, a pneumatic rod, or a hydraulic cylinder.

[0043] In this embodiment of the duct internal cleaning device, the lifting drive includes a lifting telescopic rod 22 and a two-bar linkage 23. The lower end of the lifting telescopic rod 22 is hinged to the moving mechanism 1, and the upper end of the lifting telescopic rod 22 is hinged to the lifting platform 21. The lifting telescopic rod 22 is used to drive the lifting platform 21 to move up and down. The lower end of the two-bar linkage 23 is hinged to the moving mechanism 1, and the upper end of the two-bar linkage 23 is hinged to the lifting platform 21. The lifting telescopic rod 22 and the two-bar linkage 23 are located on opposite sides of the lower part of the lifting platform 21. With this configuration, the lifting telescopic rod 22 and the two-bar linkage 23 cooperate to achieve smooth lifting and lowering of the lifting platform 21. The structure is simple, and the movement is more stable. The lifting telescopic rod 22 can be a hydraulic cylinder.

[0044] In this embodiment of the duct internal cleaning device, the cleaning actuator further includes a connecting seat 6. A first connecting rod 61 and a second connecting rod are hinged to the connecting seat 6. The first connecting rod 61 is hinged to a first brush 43, and the second connecting rod is hinged to a second brush 44. When the drive telescopic assembly 5 extends, causing the first brush 43 and the second brush 44 to move away, the first connecting rod 61 and the second connecting rod unfold, causing the connecting seat 6 to move forward. When the drive telescopic assembly 5 retracts, causing the first brush 43 and the second brush 44 to move closer, the first connecting rod 61 and the second connecting rod retract, causing the connecting seat 6 to move in the opposite direction. This configuration, with the cooperation of the connecting seat 6, the first connecting rod 61, and the second connecting rod, makes the unfolding and retraction of the first brush 43 and the second brush 44 more stable.

[0045] In this embodiment, an internal duct cleaning device further includes several auxiliary brushes. The first brush 43, the second brush 44, and the several auxiliary brushes are arranged in a circular pattern. Several auxiliary connecting rods 63 are hinged to the connecting seat 6. The first connecting rod 61, the second connecting rod, and the several auxiliary connecting rods 63 are circumferentially distributed on the connecting seat 6. The several auxiliary connecting rods 63 are hinged one-to-one with the several auxiliary brushes. When the drive telescopic component 5 extends and drives the connecting seat 6 to move forward, the connecting seat 6 drives the first brush 43, the second brush 44, and the several auxiliary brushes to expand outward to increase the cleaning range. When the drive telescopic component 5 retracts and drives the connecting seat 6 to move in the opposite direction, the connecting seat 6 drives the first brush 43, the second brush 44, and the several auxiliary brushes to retract inward to reduce the cleaning range.

[0046] With the above configuration, by adding several auxiliary brushes to cooperate with the first brush 43 and the second brush 44, a ring-shaped cleaning actuator is formed, which is suitable for round hollow pipes. The increased number of brushes makes the cleaning more comprehensive and thorough, and the efficiency is higher. At the same time, through the cooperation of the connecting seat 6 and the auxiliary connecting rod 63, the automatic opening and closing of the auxiliary brushes, the first brush 43 and the second brush 44 is realized, which can adapt to more different sizes of air ducts and is more suitable for air ducts with circular cross-sections.

[0047] In this embodiment of the duct internal cleaning device, there are two auxiliary brushes, namely a third brush 45 and a fourth brush 46, which are located on opposite sides of the connecting seat 6. The first brush 43 and the second brush 44 are located on the other opposite sides of the connecting seat 6. The structure is simple and balances cost and efficiency.

[0048] This embodiment of a duct internal cleaning device serves to clean the inner walls of ducts with different diameters (heights). The lifting platform 21, driven by a lifting actuator, moves vertically parallel to the moving mechanism 1 to adjust its height, preparing it for the brush rotation cleaning action of the cleaning actuator. The moving mechanism 1 includes a tracked platform 11 and a turntable 12. The tracked platform 11 is used for movement, and the turntable 12 is rotatably mounted on the upper part of the tracked platform 11. The lifting actuator is mounted on the turntable 12. The rotation of the turntable 12 drives the lifting actuator and the lifting platform 21 to rotate, thereby driving the cleaning actuator to rotate. The rotation axis of the turntable 12 is parallel to the vertical. The turntable 12 rotates relative to the surface of the tracked platform 11, realizing the rotation of the system. This ensures that the rolling brush of the cleaning actuator can not only brush the upper and lower walls of the square duct (achieved by the height adjustment action) but also clean the side walls of the square duct.

[0049] Drive motor 3 is a speed-regulating motor, and it is fixedly mounted on the lifting platform 21. Connector 4 is a coupling. Drive motor 3 drives the cleaning actuator to rotate and is compatible with round hollow pipes.

[0050] Example 2: As Figure 5 As shown, the duct cleaning device of this embodiment differs from that of Embodiment 1 in that it employs a different cleaning actuator. This actuator includes a transmission box 7, which is fixedly mounted on a lifting platform 21. An output shaft 71 is rotatably mounted on each opposite side of the transmission box 7, with a cleaning brush 8 coaxially fixedly connected to each output shaft 71. An input shaft 72 is rotatably mounted on the transmission box 7 and coaxially fixedly connected to the motor shaft of the drive motor 3. With this configuration, the motor shaft of the drive motor 3 drives the input shaft 72 to rotate, which, through the transmission box 7, causes the output shaft 71 to rotate, thereby driving the cleaning brush 8 to rotate and achieving cleaning of the duct's inner wall. The structure is simple and the cleaning is thorough. The drive motor 3 drives the cleaning actuator to rotate, making it suitable for square-tube-type hollow ducts.

[0051] In this embodiment of a duct internal cleaning device, a drive gear 73, a first driven gear 74, a second driven gear 75, and a balance gear 76 are installed inside the transmission box 7. The drive gear 73 is coaxially and fixedly connected to the input shaft 72; the first driven gear 74 is coaxially and fixedly connected to one of the output shafts 71, and meshes with the drive gear 73; the second driven gear 75 is coaxially and fixedly connected to the other output shaft 71, and meshes with the drive gear 73; the opposite sides of the balance gear 76 mesh with the first driven gear 74 and the second driven gear 75, respectively. With this configuration, the drive gear 73 rotates with the input shaft 72, driving the first driven gear 74 and the second driven gear 75 to rotate, thereby driving the cleaning brush 8 to rotate and clean. The balance gear 76 ensures the transmission stability between the first driven gear 74, the second driven gear 75, and the drive gear 73. Figure 5 As can be seen, the upper part of the first driven gear 74 and the upper part of the second driven gear 75 are respectively meshed with the opposite sides of the balance gear 76, and the lower part of the first driven gear 74 and the lower part of the second driven gear 75 are respectively meshed with the driving gear 73. The rotation axes of the first driven gear 74 and the second driven gear 75 coincide, and the rotation axes of the driving gear 73 and the balance gear 76 coincide. The cleaning actuator of this embodiment is more suitable for ducts with rectangular cross-sections.

[0052] In this embodiment of the duct internal cleaning device, the cleaning brush 8 includes a rotating rod 81, and bristles 82 are evenly distributed on the outer peripheral wall of the rotating rod 81. The structure is simple, and the cleaning is more thorough.
