Specific embodiments
[0018] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.
[0019] Referring to Figures 1-5 As shown, a dust cleaning device for a gas producer includes a top plate 1. A fixing ring 2 is fixedly installed on the bottom surface of the top plate 1. A pipeline 3 is provided inside the fixing ring 2. The pipeline 3 is the air outlet of the gas producer. After the gas producer is used for a long time, a large amount of soot accumulates on the inner wall of the pipeline 3. A support rod 4 is fixedly installed at the center of the top plate 1. A cleaning plate 5 is sleeved on the outer surface of the support rod 4. A motor corresponding to the support rod 4 is rotatably installed on the bottom surface of the cleaning plate 5. The motor drives the cleaning plate 5 to move along the surface of the support rod 4. The cleaning plate 5 cleans the inner wall of the pipeline 3. A fixing component 6 is fixedly installed at the lower end of the support rod 4. A first sector block 18 and a second sector block 19 are provided inside the fixing component 6. Both the first sector block 18 and the second sector block 19 are in contact with the inner wall of the pipeline 3. When the fixing component 6 is unfolded, the first sector block 18 and the second sector block 19 are in contact with the inner wall of the pipeline 3, thereby preventing the soot cleaned down from entering the gas producer and polluting the gas producer. A plurality of through grooves 7 are penetrated through the top plate 1. The plurality of through grooves 7 are circumferentially distributed about the center line of the top plate 1. An air outlet pipe 8 is fixedly installed on the upper surface of the top plate 1 corresponding to the through groove 7. One end of the air outlet pipe 8 away from the top plate 1 is fixedly installed with a dust collector 9. The dust collector 9 makes the air in the pipeline 3 flow faster, so that the soot cleaned down sequentially enters the dust collector 9 through the through groove 7 and the air outlet pipe 8, preventing the soot from being directly discharged into the atmosphere.
[0020] As Figures 3-5 shown, the fixing component 6 includes a sleeve 10. A fixing plate 11 is fixedly installed on the inner wall of the sleeve 10. A fixing pipe 12 is fixedly installed on the side of the fixing plate 11 away from the top plate 1. A plurality of sliding grooves 13 are formed on the outer surface of the fixing pipe 12. The plurality of sliding grooves 13 are circumferentially distributed about the center line of the fixing pipe 12. Slide bars 14 are provided inside the plurality of sliding grooves 13. A rotating groove 15 is formed on the surface of the slide bar 14. Two connecting rods 16 are rotatably installed on the inner wall of the rotating groove 15. One ends of the two connecting rods 16 away from the fixing pipe 12 are hingedly installed with a connecting plate 17. A plurality of first sector blocks 18 and a plurality of second sector blocks 19 are provided on the outer side of the fixing pipe 12 corresponding to the connecting plate 17. The plurality of first sector blocks 18 and the plurality of second sector blocks 19 are spaced apart about the center line of the fixing pipe 12. Both the first sector block 18 and the second sector bar are fixedly connected to the connecting plate 17. When the slide bar 14 corresponding to the first sector block 18 moves, the corresponding connecting rod 16 rotates, thereby causing the first sector block 18 to expand. After the first sector block 18 is fully expanded, the second sector block 19 expands. The expansion steps of the second sector block 19 are the same as those of the first sector block 18. The contraction sequence is opposite to the expansion sequence. During contraction, the slide bar 14 moves in the opposite direction, and the connecting rod 16 rotates under the action of gravity, thereby completing the contraction of the first sector block 18 and the second sector block 19.
[0021] As Figures 3-5 shown, a connection groove 20 corresponding to the sliding groove 13 is formed through the fixing plate 11 corresponding to the first sector block 18. A first moving rod 21 is provided inside the connection groove 20. One end of the first moving rod 21 is fixedly connected to the slide bar 14. The other end of the first moving rod 21 is fixedly installed with a circular plate 22. Two first racks 23 are fixedly installed on the side of the circular plate 22 away from the moving plate. The two first racks 23 are symmetrically distributed about the center line of the circular plate 22. A first gear 24 is provided inside the sleeve 10 corresponding to the first rack 23. The first gear 24 is meshed with the first rack 23. The first gear 24 is externally connected to a power source. The first gear 24 rotates to push the first moving rod 21 and the slide bar 14 on it to move, thereby completing the expansion and contraction of the first sector block 18.
[0022] As Figures 3-5As shown in the figure, a moving groove 25 is formed through the inner wall of the sliding groove 13 corresponding to the second sector block 19. A round rod 26 is provided inside the fixing plate 11. A second moving rod 27 is provided inside the moving groove 25. The round rod 26 is fixedly connected to the sliding rod 14 through the second moving rod 27. A second rack 28 is fixedly installed inside the round rod 26. A second gear 29 is provided inside the corresponding sleeve 10 of the second rack 28. The second gear 29 is meshed with the second rack 28. The second gear 29 is externally connected to a power source. The second gear 29 rotates to push the second rack 28 to move the sliding rod 14 on the second moving rod 27, thereby completing the expansion and contraction of the second sector block 19.
[0023] As Figures 1-5 shown, a ventilation pipe 30 corresponding to the sleeve 10 is fixedly installed at the lower end of the fixed pipe 12. Airflow enters the pipe 3 corresponding to the support rod 4 through the ventilation pipe 30, and the ventilation pipe 30 helps the first sector block 18 and the second sector block 19 to expand.
[0024] Working principle: The staff places the whole device into the pipe 3 and makes the pipe 3 enter the fixing ring 2. The first gear 24 rotates to push the first rack 23 to move the first connecting rod 16, thereby making the sliding rod 14 push the first sector block 18 to move. The first sector block 18 contacts the ventilation pipe 30, thereby making the connecting rod 16 rotate, so that the first sector block 18 is completed to expand. The expansion step of the second sector block 19 is the same as that of the first sector block 18. When the first sector block 18 and the second sector block 19 are completely expanded, the cleaning plate 5 moves along the surface of the support rod 4 to complete the cleaning of the inner wall of the pipe 3. At the same time, the dust collector 9 is started, so that the cleaned soot is collected by the dust collector 9 in turn through the through groove 7 and the air outlet pipe.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
