The output shaft of the first motor 26 passes through the first connecting hole 25 and is fixedly connected to the first gear 24. Side panels 27 are symmetrically fixedly connected to the bottom surface of the rotating seat 22, and a smoke exhaust machine body 213 is installed between the side panels 27.

[0018] In the embodiment, when in use, the unmanned aerial vehicle body 1 carries the smoke cleaning structure 2 to move into a building where a fire occurs, and then the smoke exhaust machine body 213 is started to clean the smoke in the building. When the orientation of the smoke exhaust machine body 213 needs to be adjusted, the first motor 26 is started to drive the first gear 24 to rotate. When the first gear 24 rotates, the outer gear ring 23 and the rotating seat 22 are driven to rotate together, so that the orientation of the smoke exhaust machine body 213 is adjusted, thereby the orientation of the smoke exhaust machine body 213 can be adjusted without adjusting the orientation of the unmanned aerial vehicle body 1, which is convenient for the firefighters to clean the smoke in the building.

[0019] Further, as shown in Figures 3 to 5 ; In combination with the above content: In order to adjust the angle of the smoke exhaust machine body 213, in an optional embodiment, a second connecting hole 28 is formed in each side plate 27, and a rotating column 29 is rotatably connected in each second connecting hole 28.

[0024] In this embodiment, when the protection cover 32 is installed, the second threaded column 312 on the mounting ring 31 is placed in the fifth connecting hole 311, and then the second nut 313 is arranged on the second threaded column 312 to fix the mounting ring 31, thereby completing the installation of the protection cover 32, protecting the smoke cleaning structure 2, and prolonging the service life.

[0025] Further, As shown in Figures 4 to 5 ; In combination with the above: In order to guarantee the smoke cleaning effect of the smoke exhaust machine body 213, in an optional embodiment, the protective cover 32 is provided with an air outlet 33 near the air outlet end of the smoke exhaust machine body 213, and the protective cover 32 is provided with an air inlet 34 near the air inlet end of the smoke exhaust machine body 213.

The bottom surface of each second positioning plate 37 is fixedly connected with a positioning rod 38. The inner wall of the protective cover 32 is fixedly connected with a first positioning plate 35 near each second positioning plate 37. Each first positioning plate 35 is provided with a fourth connecting hole 36. The positioning rod 38 is arranged in the fourth connecting hole 36.

[0026] In the embodiment, when the rotating seat 22 rotates, the second positioning plate 37 moves in a circular motion, and the first positioning plate 35 moves together with the second positioning plate 37, so that the first positioning plate 35 drives the protective cover 32 to rotate together, and the position of the air inlet 34 and the air outlet 33 can be synchronized with the position of the smoke exhaust machine body 213, thereby guaranteeing the smoke exhaust effect.

[0027] Further, as shown in Figure 1 and Figure 6 ; In combination with the above content: In order to facilitate the maintenance of the smoke cleaning structure 2, in an optional embodiment, the bottom surface of the protective cover 32 is provided with a bottom cover 39. The top surface of the bottom cover 39 is fixedly connected with a ring-shaped plate 310. The outer wall of the ring-shaped plate 310 is provided with external threads. The bottom position of the inner wall of the protective cover 32 is provided with internal threads. The ring-shaped plate 310 is screw-connected with the protective cover 32.

[0028] In the embodiment, the ring-shaped plate 310 can be separated from the protective cover 32 by rotating the bottom cover 39, thereby facilitating the maintenance of the smoke cleaning structure 2 by the firefighters.

[0029] ​The working principle and use process of the present application: when installing the smoke cleaning structure 2, the first threaded column 219 on the mounting column 218 can be placed into the mounting hole 12 on the mounting frame 11, then the first nut 220 is arranged on the first threaded column 219 to fix the mounting plate 21, which facilitates the installation of the smoke cleaning structure 2. When installing the protective cover 32, the second threaded column 312 on the mounting ring 31 is placed in the nearby fifth connecting hole 311, then the second nut 313 is used on the second threaded column 312 to fix the mounting ring 31, thereby completing the installation of the protective cover 32, which protects the smoke cleaning structure 2 and prolongs its service life. In use, the unmanned aerial vehicle body 1 carries the smoke cleaning structure 2 to move into the building where the fire occurs, then the smoke exhaust machine body 213 is started to remove the smoke in the building. When the orientation of the smoke exhaust machine body 213 needs to be adjusted, the first motor 26 is started to drive the first gear 24 to rotate. When the first gear 24 rotates, it drives the outer gear ring 23 to rotate together, and the outer gear ring 23 drives the rotating seat 22 to rotate together, thereby adjusting the orientation of the smoke exhaust machine body 213, so that the orientation of the smoke exhaust machine body 213 can be adjusted without adjusting the orientation of the unmanned aerial vehicle body 1, which facilitates the fire-fighting personnel to remove the smoke in the building. When the angle of the smoke exhaust machine body 213 needs to be adjusted, the second motor 217 is started to drive the third gear 215 to rotate, which drives the second gear 214 to rotate together. When the second gear 214 rotates, it drives the connected rotating column 29 to rotate, thereby driving the connecting plate 211 to rotate, which adjusts the angle of the smoke exhaust machine body 213, facilitating the fire-fighting personnel to disperse the smoke at different positions in the building, improving the smoke cleaning effect of the building. When the rotating seat 22 rotates, it drives the second positioning plate 37 to move in a circular motion, which drives the first positioning plate 35 to move together, thereby driving the first positioning plate 35 to rotate together with the protective cover 32, which synchronizes the positions of the air inlet 34 and the air outlet 33 with the position of the smoke exhaust machine body 213, thereby ensuring the smoke exhaust effect.
