Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 6A spiral structure sonic soot blower comprises a shell 1, a turbine 6 is installed on the top of the shell 1, one end of the air inlet of the turbine 6 is connected with a hollow shell 15, and the hollow shell 15 is located inside the shell 1, and the circumferential outer wall of the hollow shell 15 is fixed with an upper spiral plate 14 and a lower spiral plate 18 by bolts, and a plurality of air holes 19 are opened inside the lower spiral plate 18, and an air bag 21 is arranged on the top of the air hole 19, and an air passage 20 is formed between the adjacent upper spiral plates 14 and lower spiral plates 18. The turbine 6 rotates to make the external gas enter the shell 1 and the hollow shell 15 through the connecting pipe 17, and the gas moves upward through the air passage 20 between the upper spiral plate 14 and the lower spiral plate 18, and is affected by the air bag 21 during the movement. When passing through the air bag 21, the air bag 21 contracts, and the sound becomes louder when passing over the air bag 21. A sound transmission hole 10 is opened on one side of the shell 1, and one side of the sound transmission hole 10 is connected by a connecting component An amplifier 9 is installed, a sealing plate 13 is fixed in the sound transmission hole 10 by bolts, a connecting pipe 17 is connected and fixed at the bottom end of the shell 1, a slide groove 11 is opened on the circumferential inner wall of the connecting pipe 17, a rotating ring 16 is slidably connected in the slide groove 11, an impeller 12 is fixed inside the rotating ring 16 by bolts, a connecting plate 26 is fixed on the top of the impeller 12 by bolts, a stopper 27 is welded on the circumferential outer wall of the connecting plate 26, and the stopper 27 can block the gap surrounded by the bottom end points of the upper spiral plate 14 and the lower spiral plate 18. The impeller 12 rotates to make the connecting plate 26 drive the stopper 27 to rotate, so that the stopper 27 intermittently blocks the gap surrounded by the bottom end points of the upper spiral plate 14 and the lower spiral plate 18, so that the sound emitted is further increased, and finally the gas is discharged through the air outlet of the turbine 6, and the sound is released through the sound transmission hole 10 and the amplifier 9. A knocking component is provided inside the hollow shell 15 to further increase the sound.

[0031] In the present invention, it should be noted that the knocking assembly includes a connecting shaft 25, which is rotatably connected to the bottom of the hollow shell 15, and the bottom end of the connecting shaft 25 passes through the hollow shell 15 and is fixed to the connecting disk 26. A plurality of pull ropes 24 are installed on the circumferential outer wall of the connecting shaft 25, and a knocking block 23 is provided at one end of the pull rope 24. A protrusion 22 is fixed to the circumferential inner wall of the hollow shell 15 by bolts, and the knocking block 23 is in contact with the protrusion 22. The connecting disk 26 rotates so that the pull rope 24 drives the knocking block 23 to rotate under the action of centrifugal force. The knocking block 23 knocks the protrusion 22 to emit sound waves. The bottom of the connecting pipe 17 is connected and fixed with an air guide cover 2, which can allow external gas to be introduced into the connecting pipe 17. The connecting component includes an inner joint 7, which is fixed to one side of the sound transmission hole 10 by bolts. One end of the inner joint 7 is threadedly connected to an external joint 8, and the external joint 8 is fixed to the amplifier 9. The external joint 8 and the inner joint 7 are connected by threads, which is convenient for the staff to disassemble the external joint 8, and then convenient for the staff to replace the amplifier 9. A first limit block 30 is welded to the outer wall of one side of the head 8, and an arc-shaped groove 31 is opened on one side of the first limit block 30. A second limit block 34 is welded to the outer wall of one side of the inner joint 7, and a mounting groove 33 is opened on one side of the second limit block 34. An elastic ball 32 is bonded in the mounting groove 33, and the elastic ball 32 is snap-fitted with the arc-shaped groove 31. Through the coordinated use of the elastic ball 32 and the arc-shaped groove 31, the position between the inner joint 7 and the outer joint 8 is further restricted, so as to prevent the outer joint 8 from easily rotating in the reverse direction and causing the inner joint 7 to be in conflict with the outer joint 8. The joint 7 is loosely connected, and two connecting rods 4 are fixed to the outer walls of both sides of the shell 1 by bolts. One end of the two connecting rods 4 is welded with a mounting block 3, which is convenient for the staff to connect and fix the device. Two fixing blocks 5 are fixed to one side of the mounting block 3 by bolts, and the fixing block 5 is fixed to the connecting rod 4. The fixing block 5 makes the connection between the mounting block 3 and the connecting rod 4 more firmly. A cavity 28 is opened inside the shell 1, and sound insulation cotton 29 is arranged in the cavity 28. The sound insulation cotton 29 can make the shell 1 have a sound insulation effect.

[0032] The working principle of this embodiment is as follows: the rotation of the turbine 6 allows the external gas to enter the shell 1 and the hollow shell 15 through the connecting pipe 17, and the gas moves upward through the air passage 20 between the upper spiral plate 14 and the lower spiral plate 18. During the movement, the gas is affected by the air bag 21. When passing through the air bag 21, the air bag 21 contracts, and the sound becomes louder when passing over the air bag 21. At the same time, the impeller 12 rotates, so that the connecting disk 26 drives the block 27 to rotate, so that the block 27 intermittently blocks the gap surrounded by the bottom end points of the upper spiral plate 14 and the lower spiral plate 18, so that the sound emitted becomes larger. At the same time, the rotation of the connecting disk 26 causes the pull rope 24 to drive the knocking block 23 to rotate under the action of centrifugal force, so that the knocking block 23 knocks the protrusion 22 to emit sound waves, and finally the gas is discharged through the air outlet of the turbine 6, and the sound is released through the sound transmission hole 10 and the amplifier 9.
