[0017] The present invention arranges a distance plate, an inclined frame A, a cleaning plate and an inclined frame B. The elastic structure has a tendency to push the movable plate away from the fixed plate. The two distance plates are controlled to be inserted between the gaps between the two pipe segments. The ends of the two distance plates that are away from each other are respectively in contact with the sides of the two pipe segments that are close to each other. The upper end of the distance plate drives the movable plate to move relative to the fixed plate by moving in the inclined frame A. At the same time, the movable plate approaches the lower plate through the upper plate. The inclined frame B moves downward synchronously with the upper plate, driving the cleaning plate to change the distance from the axis of the lower plate, so that the cleaning plate just contacts the end surface of the pipe segment. When the motor A drives the upper plate to rotate, the cleaning plate and the lower plate are driven to rotate through the inclined frame B, so that the cleaning plate cleans the debris inside the gap between the two pipes when rotating, and the cleaning range of the cleaning plate is equal to the gap width between the pipes, without causing damage to the end surface of the pipes.

[0018] The present invention is provided with an air bag cleaning strip, an inner prism tube, a plug, a pressure relief hole and an elastic telescopic rod. The air supply structure supplies air to the inside of the cavity disk through the ventilation structure. The air bag cleaning strip expands under the filling of gas, thereby increasing the hardness of the air bag cleaning strip. Then, when the cavity disk rotates, the air bag cleaning strip is driven to hit and clean the blockage in the gap between the tube sheets. As the air pressure inside the cavity disk increases, the plug is pushed to stretch the gas pressure spring to move outward. When the plug moves to the outside of the pressure relief hole located on the outer surface of the cavity disk, the gas is discharged from the pressure relief hole to limit the maximum air pressure in the cavity disk. When the air bag cleaning strip hits the harder blockage, the degree to which the air bag cleaning strip moves relative to the inner prism axis to compress the elastic telescopic rod increases, driving the inner prism tube to rotate and engage with the threaded ring to move into the cavity disk, increasing the moving distance of the plug to the right side of the pressure relief hole on the outer side of the cavity disk, thereby increasing the air pressure in the cavity disk, and simultaneously increasing the hardness of the air bag cleaning strip after being filled with air pressure, thereby increasing the striking and cleaning effect of the air bag cleaning strip on the blockage when it rotates.

[0019] The present invention provides an axis plate and a side baffle rod, and the toothless gear intermittently meshes with the spur gear C to drive the torsion frame to rotate intermittently. After the toothless gear is disengaged from the spur gear C, the torsion frame is reset under the elastic connection with the fixed plate. The two side baffle rods block the axis plate to limit the rotation range of the torsion frame. When the torsion frame swings, it drives the airbag cleaning strip to swing, thereby increasing the cleaning width.

[0020] The present invention provides a blocking rod and an air jet angle rod. The air jet angle rod blows air from between two distance plates toward one side of the cleaning plate to blow the blockage cleaned by the cleaning plate out from between the two pipe segments. A plurality of mutually contacting blocking rods seal the space between the auxiliary plate and the pipe segment to prevent the blockage from being scattered by the airflow. The blockage is driven by the airflow into the dust collecting box through the connecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The movable plate 13 and the fixed plate 12 are elastically connected through an elastic structure 5. The elastic structure 5 includes a slotted fork tube 51, and the upper end of the slotted fork tube 51 is fixed to the bottom surface of the movable plate 13. The fixed plate 12 is slidably sleeved on the lower end of the slotted fork tube 51. A push spring 52 is fixed to the upper surface of the fixed plate 12, and the upper end of the push spring 52 is fixed to the movable plate 13.

The push spring 52 has a tendency to push the movable plate 13 away from the fixed plate 12.

[0036] The upper surface of the fixed plate 12 is slidably penetrated by two distance plates 15, and one end of the two distance plates 15 located above the fixed plate 12 is slidably connected with an inclined frame A14, and the upper end of the inclined frame A14 is fixed to the bottom surface of the movable plate 13. The upper surface of the fixed plate 12 is rotatably penetrated by a lower plate 16, and an upper plate 17 is arranged above the lower plate 16. The movable plate 13 is rotatably sleeved on the outer surface of the upper plate 17, and a plurality of inclined frames B18 are fixed to the bottom surface of the upper plate 17. The inclined frames A14 and the inclined frames B18 have the same inclination angle, and the bottom surface of the lower plate 16 is located below each inclined frame B18.

The outer annular surface of the cavity disk 22 is fixedly connected with multiple air bag cleaning strips 24. The air bag cleaning strips 24 expand and harden after being filled with gas. When the air bag cleaning strips 24 rotate with the cavity disk 22, they can knock on the blockages between the pipe segments and pre-clean the blockages between the pipe segments. The front end of the cavity disk 22 is slidably inserted with a rotatable deflation structure 7, and the interior of the deflation structure 7 is connected to the interior of the cavity disk 22. An elastic telescopic rod 25 is fixed to one end of the deflation structure 7 located inside the cavity disk 22, and the other end of the elastic telescopic rod 25 is fixed to the inner annular surface of the cavity disk 22.

[0041] A power structure 8 is disposed at the front side of the torsion frame 21 . The power structure 8 is connected to the left end of the fixing plate 12 , and an output end of the power structure 8 is connected to the front end of the air release structure 7 .

[0042] The deflation structure 7 includes an inner prism tube 71, a plug 72 and a gas spring 73. The plug 72 is slidably inserted into the inner prism tube 71. One end of the gas spring 73 is fixed to the inner wall of the inner prism tube 71 located inside the cavity disk 22. The other end of the gas spring 73 is fixed to the plug 72. The end of the inner prism tube 71 located inside the cavity disk 22 is threadedly sleeved with a threaded ring 74. The threaded ring 74 is fixed to the inner wall of the cavity disk 22.

The inner prism 71 is connected to the cavity disk 22, and a plurality of pressure relief holes 77 are provided on the outer ring surface of one end thereof. The elastic telescopic rod 25 has a tendency to stretch. When the elastic telescopic rod 25 is at the maximum stretching depth, the inner prism 71 drives all the pressure relief holes 77 to be located outside the cavity disk 22. As the air pressure in the cavity disk 22 increases, the air pressure pushes the plug 72 to gradually stretch the gas spring 73. When the plug 72 moves to the right side of the pressure relief hole 77 outside the cavity disk 22, the gas in the cavity disk 22 is discharged from the pressure relief hole 77 on the left side of the plug 72, and the maximum pressure in the cavity disk 22 is limited. When the airbag cleaning strip 24 is blocked by the harder plug When an object is hit, the degree to which the airbag cleaning strip 24 moves relative to the inner prism shaft 75 and compresses the elastic telescopic rod 25 increases, driving the inner prism tube 71 to rotate and engage with the threaded ring 74 to move into the cavity disk 22, thereby increasing the moving distance of the plug 72 to the right side of the pressure relief hole 77 outside the cavity disk 22, thereby increasing the air pressure in the cavity disk 22, and simultaneously increasing the hardness of the airbag cleaning strip 24 after being filled with air pressure, thereby increasing the impact and cleaning effect of the airbag cleaning strip 24 on the blockage when it rotates, and the driven bevel gear A76 drives the inner prism shaft 75 to rotate synchronously through the inner prism tube 71, and the inner prism shaft 75 drives the cavity disk 22 to rotate through the elastic telescopic rod 25.

[0043] The power structure 8 includes a motor C81 and a long shaft 82, the long shaft 82 is rotatably connected to the torsion frame 21, the upper part of the driven bevel gear A76 is meshed with a driving bevel gear A83, the driving bevel gear A83 is coaxially fixed to the lower end of the long shaft 82, the upper end of the long shaft 82 is coaxially fixed with a driven gear B84, one side of the driven gear B84 is meshed with a driving gear B85, the upper end of the torsion frame 21 is a round rod, the round rod end of the torsion frame 21 is rotatably connected to the fixed plate 12, the ventilation structure 6 includes an air cavity ring 61, the axis of the air cavity ring 61 is coaxially arranged with the rod-shaped structure of the torsion frame 21, and the air cavity ring 61 A torsion ring 62 is rotatably inserted into the bottom surface, which closes the bottom end of the air cavity ring 61 and can rotate relative to the air cavity ring 61. A bent pipe 63 is rotatably inserted into the back axis of the cavity disk 22. The upper end of the bent pipe 63 is fixedly penetrated through the bottom surface of the torsion ring 62. The upper surface of the air cavity ring 61 is fixedly connected with an air supply pipe 64. The cavity box 11 and the main board 4 are fixedly sleeved on the outer surface of the air supply pipe 64, and the air supply structure 23 is fixedly connected to the upper end of the air supply pipe 64. When the torsion frame 21 drives the cavity disk 22 to twist, the torsion ring 62 is driven to rotate on the bottom surface of the air cavity ring 61 through the bent pipe 63.

[0044] The driving gear B85 is coaxially arranged with the round rod end of the torsion frame 21, and the driving gear B85 is rotatably connected with the bottom surface of the fixed plate 12. A spur gear A86 is coaxially fixed to the outer ring surface of the driving gear B85, and a spur gear B87 is meshed with one side of the spur gear A86. The spur gear B87 is fixed to the output end of the motor C81, and the motor C81 is fixed to the fixed plate 12. The round rod end of the torsion frame 21 is located above the fixed plate 12 and is fixedly sleeved with a spur gear C88. The spur gear B87 is meshed with the spur gear A86 to drive the driving gear B85 to rotate. The driving gear B85 is meshed with the driven gear B84 to drive the long shaft 82 and the driving bevel gear A83 to rotate, and the driving bevel gear A83 drives the inner prism 71 to rotate synchronously.

The lower end of the side baffle 892 is fixed to the upper surface of the fixed plate 12. The missing tooth gear 89 drives the torsion frame 21 to rotate intermittently by intermittently meshing with the spur gear C88. After the missing tooth gear 89 is disengaged from the spur gear C88, the torsion frame 21 is reset under the elastic connection with the fixed plate 12. The two side baffles 892 limit the rotation range of the torsion frame 21 by blocking the axis plate 891. When the torsion frame 21 swings, it drives the airbag cleaning strip 24 to swing, thereby increasing the cleaning width.

[0045] The working principle is as follows: when it is necessary to clean and powder the gaps between the pipe segments, the powered telescopic moving frame 1 is telescoped to change the height of the main shaft 3, and then the motor B32 drives the main shaft 3 to rotate to change the orientation of the main plate 4 and the auxiliary plate 10, so that the pipe segment gaps at different angles can be processed, and the blocking rod 33 is controlled to contact the pipe segment, so that a closed structure is formed between multiple contacting blocking rods 33, the auxiliary plate 10 and the pipe segment, and the two distance plates 15 are controlled to be inserted between the gaps between the two pipe segments, and the two distance plates 15 are pushed close to each other, and the ends of the two distance plates 15 that are away from each other are respectively in contact with the sides of the two pipe segments that are close to each other, and the upper end of the distance plate 15 drives the movable plate 13 to move relative to the fixed plate 12 by moving in the inclined frame A14, and at the same time, the movable plate 13 approaches the lower plate 16 through the upper plate 17, and the inclined frame B18 moves downward synchronously with the upper plate 17, driving the cleaning The cleaning plate 19 changes the distance from the axis of the lower plate 16 so that the cleaning plate 19 just contacts the end face of the pipe segment. The airbag cleaning strip 24 expands under gas filling, increasing the hardness of the airbag cleaning strip 24. Then, when the cavity plate 22 rotates, the airbag cleaning strip 24 is driven to hit the blockage in the gap between the pipe segments for pre-cleaning. When the motor A20 drives the upper plate 17 to rotate, the cleaning plate 19 and the lower plate 16 are driven to rotate through the inclined frame B18, so that the cleaning plate 19 cleans the debris inside the gap between the two pipes during rotation, and the cleaning range of the cleaning plate 19 is equal to the width of the gap between the pipes. The jet angle rod 27 blows air from between the two spacing plates 15 toward one side of the cleaning plate 19 to blow the blockage cleaned by the cleaning plate 19 out from between the two pipe segments. The airflow drives the blockage through the connecting pipe 29 into the dust collecting box 28, which is convenient for later powder spraying and filling between the pipe segments.
