Driving blocks 4 are installed on the outer surfaces of the four reciprocating screws 3, and a mounting plate 5 is installed between the four driving blocks 4. When the four reciprocating screws 3 rotate at the same time, the mounting plate 5 can be driven to reciprocate and rise and fall through the action of the driving blocks 4. Six sleeves 6 are installed on the upper surface of the mounting plate 5 in a coaxial array around the pipe body 1, a striking rod 7 is inserted inside the sleeve 6, an inner groove 8 is opened on the inner wall of the sleeve 6, a shoulder 9 is provided on the outer surface of the striking rod 7, a spring 10 is sleeved on the outer surface of the striking rod 7, both ends of the spring 10 are respectively in contact with the shoulder 9 and the inner wall of the inner groove 8, one end of the striking rod 7 extends to the outside of the sleeve 6, and the other end is inside the sleeve 6. When the striking rod 7 moves rapidly toward the pipe body 1, its end can extend from the inside of the sleeve 6 and hit the surface of the pipe body 1. During the movement of the striking rod 7, it drives the shoulder 9 to compress the spring 10. Therefore, after the striking rod 7 hits the surface of the pipe body 1, the striking rod 7 can be quickly reset by the reaction force and the elastic force of the spring 10.

[0023] The upper side of the mounting plate 5 is provided with a striking mechanism 11 capable of intermittently pushing the striking rod 7 to move. Through the setting of the striking mechanism 11, the six striking rods 7 can be driven to intermittently strike the surface of the pipe body 1 at the same time. The outer side of the two fixed plates 2 is provided with a driving mechanism 17 capable of driving the four reciprocating screws 3 to rotate simultaneously. Through the setting of the driving mechanism 17, the striking rod 7 can strike the entire surface of the pipe body 1, thereby achieving the purpose of cleaning the inside of the pipe body 1 as a whole. A dust removal mechanism 21 is provided on the top of the pipe body 1. Through the setting of the dust removal mechanism 21, dust can be removed from the flue gas when it is discharged to reduce pollution to the air environment.

[0024] A silicone pad 31 is provided at the end of the striking rod 7 facing the pipe body 1 . The provision of the silicone pad 31 can prevent the striking rod 7 from directly and rigidly contacting the pipe body 1 , which would cause concave deformation on the surface of the pipe body 1 .

A motor A15 is mounted on the outer surface of the mounting plate 5. A gear 16 is mounted on the end of the output shaft of the motor A15. The gear 16 is meshed and connected with the gear ring 12. The gear 16 is driven to rotate by starting the motor A15. Since the gear 16 and the gear ring 12 are meshed with each other, This can drive the gear ring 12 to rotate rapidly, and during the rapid rotation of the gear ring 12, it drives the wedge block A13 to continuously squeeze the wedge block B14, and then the wedge block B14 can drive the striking rod 7 to move rapidly toward the pipe body 1 and strike the pipe body 1. The reaction force generated by the striking and the elastic force of the spring 10 can enable the striking rod 7 to quickly reset and drive the wedge block B14 back to the initial position. Under the continued rotation of the gear ring 12, the striking rod 7 can intermittently strike the pipe body 1, thereby achieving the purpose of cleaning the inside of the pipe body 1.

[0027] The driving mechanism 17 includes a motor B18 installed at the bottom of the lower fixed disk 2. The output shaft of the motor B18 is connected to one of the reciprocating screws 3. The upper ends of the four reciprocating screws 3 all penetrate the upper side of the upper fixed disk 2 and are installed with pulleys 19. The four pulleys 19 are commonly engaged with a transmission belt 20. When the inside of the pipeline body 1 is cleaned by the striking mechanism 11, the motor B18 can be started. The motor B18 drives the reciprocating screw 3 connected to it to rotate. Through the transmission action of the transmission belt 20, the four reciprocating screws 3 can be driven to rotate synchronously. The four reciprocating screws 3 drive the driving blocks 4 on their surfaces to reciprocate and rise and fall, thereby achieving the purpose of driving the mounting disk 5 to reciprocate and rise and fall, so that the striking rod 7 can strike the surface of the entire pipeline body 1, thereby achieving the purpose of cleaning the inside of the pipeline body 1.

[0028] The dust removal mechanism 21 includes four support rods 22 installed on the top of the pipeline body 1, and a top plate 23 is installed on the top of the four support rods 22. A guide cover 24 is installed on the outer surface of the pipeline body 1 near the upper end, and an annular water pipe 25 is installed on the upper surface of the top plate 23. Atomizing nozzles 26 are evenly installed on the outer surface of the annular water pipe 25. The outer surface of the annular water pipe 25 is connected to a water inlet pipe 27, and the end of the water inlet pipe 27 is connected to a water pump. The outer surface of the guide cover 24 is connected to a drain pipe 28. After the smoke is discharged from the top of the pipeline body 1, it is blocked by the top plate 23 and diffuses to the surroundings, and is discharged from the top plate 23. 3 and the gap between the deflector 24, then the water pump is started to deliver water to the inside of the annular water pipe 25 through the water inlet pipe 27, and sprayed on the flue gas through the atomizing nozzle 26 to play a role in dust reduction. Since the local concentration of the flue gas is reduced after being diffused, the spraying effect of the atomizing nozzle 26 can play a good role in dust removal and reduce the pollution of the flue gas to the environment. The sewage after flushing is directly discharged from the drain pipe 28 without manual regular cleaning, thereby reducing the workload of workers and the difficulty of maintenance. The sewage discharged from the drain pipe 28 can be reused by sedimentation filtration.

[0029] The working principle of the utility model is as follows: during use, smoke flows from the inside of the pipe body 1 and is discharged from the top thereof. The smoke is blocked by the top plate 23 and diffuses to the surroundings, and flows between the top plate 23 and the air guide cover 24. Then, water is pumped into the annular water pipe 25 through a water pump, and sprayed on the smoke through an atomizing nozzle 26, which plays a role in dust reduction. The sewage after flushing is directly discharged from the drain pipe 28. Therefore, there is no need to manually clean the dust removal mechanism 21 regularly. When there is a lot of dust attached to the inner wall of the pipe body 1, the motor A15 and the motor B18 can be started at the same time. The motor A15 drives the gear 16 to rotate, and then drives the gear ring 12 Rotate and make the wedge block A13 continuously squeeze the wedge block B14, drive the striking rod 7 to intermittently strike the surface of the pipe body 1, and make the pipe body 1 vibrate by striking, so as to shake off the dust attached to the inner wall of the pipe body 1, and at the same time, the motor B18 drives the reciprocating screw 3 connected to it to rotate, and through the transmission action of the transmission belt 20, it can drive the four reciprocating screws 3 to rotate synchronously, and the four reciprocating screws 3 drive the driving block 4 on its surface to reciprocate and rise and fall, so as to achieve the purpose of driving the mounting plate 5 to reciprocate and rise and fall, so that the striking rod 7 can strike the surface of the entire pipe body 1, so as to achieve the purpose of cleaning the inside of the pipe body 1, avoid blockage, and ensure the normal circulation of flue gas.

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
