The outer ring surface of the disc 12-1 is fixedly sleeved with a sealing ring.
Sealing layers are fixedly arranged on the outer cambered surfaces of the first arc-shaped plates 12-50 and the second arc-shaped plates 12-51.
Working principle: when the device is used, the inner diameter of the pipeline is required to be matched with the diameter of the disc 12-1, when the device is used for cleaning the scale in the warm through pipe, the device is firstly moved to the open end of the warm through pipe, and the scale in the range which is enough to be obtained by hands at the open end of the warm through pipe is cleaned (namely, the scale on the inner wall of the pipeline in the range of 30-50cm at the open end of the pipeline is scraped off so as to facilitate the placement of the pipeline scale cleaning mechanism 12).
Then deforming the deformable rings 12-49 on the pipeline scale cleaning mechanism 12 to reduce the volume of the deformable rings 12-49, wherein the process of reducing the volume of the deformable rings 12-49 is as follows; firstly, two electric telescopic rods 12-28 run, the telescopic ends of the two electric telescopic rods 12-28 are synchronously extended, the conical discs 12-24 are pushed to the disc 12-1 direction when the telescopic ends of the two electric telescopic rods 12-28 are synchronously extended, when the telescopic ends of the two electric telescopic rods 12-28 are the largest in length, the conical discs 12-24 are moved out of the deformable ring 12-49, at the moment, the conical discs 12-24 are positioned at one side of the deformable ring 12-49, at the moment, the two second electric telescopic rods 12-52 run, the telescopic ends of the two second electric telescopic rods 12-52 retract, so that the two second arc-shaped plates 12-51 are respectively driven by the two second electric telescopic rods 12-52 to be close to each other, when the telescopic ends of the two second electric telescopic rods 12-52 are respectively retracted to the largest, the opposite sides of the two second curved plates 12-51 are just attached (as shown in fig. 6), so that the two second curved plates 12-51 are separated from the two first curved plates 12-50, the two second curved plates 12-51 and the two first curved plates 12-50 are in independent states, at the moment, the telescopic ends of the two first electric telescopic rods 12-30 retract, so that the two first electric telescopic rods 12-30 simultaneously drive the sleeves 12-32 to move towards the first fixing ring 12-29, the sleeves 12-32 synchronously drive the two second curved plates 12-51 to move when moving, when the telescopic ends of the first electric telescopic rods 12-30 retract to the maximum degree, the two second curved plates 12-51 are positioned at the side ends of the first curved plates 12-50, at this time, the telescopic ends of the two third electric telescopic rods 12-34 are retracted, so that the two third electric telescopic rods 12-34 respectively drive the two first arc plates 12-50 to approach each other, when the telescopic ends of the two third electric telescopic rods 12-34 are retracted to the maximum extent, the opposite ends of the two first arc plates 12-50 are attached, at this time, due to the mutual approach of the two first arc plates 12-50 and the mutual approach of the two second arc plates 12-51, the space occupied by the two first arc plates 12-50 and the two second arc plates 12-51 is reduced (as shown in fig. 7), and the volume of the deformable ring 12-49 is reduced in a deformation manner, so that when the pipeline scale cleaning mechanism 12 is put into a pipeline, the deformable ring 12-49 is not blocked by scale on the inner wall of the pipeline.
After the volume deformation of the deformable circular ring 12-49 is reduced, the pipeline scale cleaning mechanism 12 is lifted up from the base 1, and is inserted into a pipeline through the opening end of the warm through pipe (as shown in fig. 5), when the pipeline scale cleaning mechanism 12 enters the pipeline, the diameter of the circular disk 12-1 is matched with the inner diameter of the pipeline, so that the outer ring surface of the circular disk 12-1 is just sealed and attached to the inner wall of the opening of the pipeline (as the scale on the inner wall of the opening of the pipeline is cleaned in advance, the circular disk 12-1 does not get stuck when entering the pipeline), at this time, the four rollers 12-13 are tightly attached to the inner wall of the pipeline, and when the four motors 12-12 operate, the four rollers 12-13 can realize synchronous rolling, and can realize synchronous reverse rolling of the four rollers 12-13 by controlling forward and reverse rotation of the motors 12-12, so that the function of advancing or retreating of the pipeline scale cleaning mechanism 12 in the pipeline can be realized through the four rollers 12-13.
When all the four rollers 12-13 on the pipeline scale cleaning mechanism 12 enter the pipeline, the cleaning work of the scale in the pipeline can be started, and the cleaning work of the scale in the pipeline is as follows; firstly, the second motor 12-45 is operated to enable the grinding roller 12-46 to rotate at a high speed, then the telescopic end of the fourth electric telescopic rod 12-47 is extended, so that the grinding roller 12-46 is slowly contacted with scale on the inner wall of a pipeline along with the extension of the telescopic end of the fourth electric telescopic rod 12-47, when the telescopic end of the fourth electric telescopic rod 12-47 is extended to the maximum extent, the grinding roller 12-46 is just attached to the inner wall of the pipeline, at the moment, the third motor 12-56 is operated, when the third motor 12-56 is operated, the first cylinder 12-38 is driven to slowly rotate through the first gear 12-57 and the first toothed ring 12-54, the grinding roller 12-46 is synchronously driven to rotate together when the first cylinder 12-38 is slowly rotated, so that after the first cylinder 12-38 rotates for 360 DEG, the polishing roller 12-46 polishes an annular groove on a scale layer on the inner wall of the pipeline, at the moment, the second motor 12-45 stops running, the telescopic end of the fourth electric telescopic rod 12-47 is retracted to the original position, meanwhile, the telescopic end of the fifth electric telescopic rod 12-39 is extended to the maximum extent, the arc surface at the bottom of the V-shaped scraping plate 12-40 is stuck to the inner wall of the pipeline, thus the V-shaped scraping plate 12-40 pushes the scale ground by the polishing roller 12-46 to two sides along with the continuous rotation of the first cylinder 12-38 (scale residues ground by the polishing roller 12-46, most of the scale residues fall to the bottom of the pipeline, in order to put the deformable ring 12-49 into the annular groove ground by the polishing roller 12-46, the scale residues at the bottom of the annular groove must be pushed to two sides, the outer ring surface of the deformable circular ring 12-49 can be better attached to the inner wall of the pipeline, so that the sealing performance is guaranteed), when the first barrel 12-38 continues to rotate for a rotation angle of 720-1480 ℃, the third motor 12-56 stops running, the telescopic end of the fifth electric telescopic rod 12-39 drives the V-shaped scraping plate 12-40 to retract to the original position, at the moment, the four motors 12-12 run, the four rollers 12-13 roll synchronously, the pipeline scale cleaning mechanism 12 is slowly pushed to move to the deep part of the pipeline, and when the first arc plate 12-50 moves to the position between annular grooves on the scale layer in the pipeline (when the pipeline scale cleaning mechanism 12 moves forward for 20-30cm under the drive of the four rollers 12-13), the four motors 12-12 stop running, at the moment, the deformable circular ring 12-49 becomes larger, and the variable circular ring 12-49 becomes larger than Cheng Ruxia; the telescopic ends of the two third electric telescopic rods 12-34 are firstly extended to the greatest extent, so that the two first arc-shaped plates 12-50 respectively prop against the inner top wall and the inner bottom wall of the pipeline, then the telescopic ends of the two first electric telescopic rods 12-30 are extended to the greatest extent, so that the two second arc-shaped plates 12-51 move between the two first arc-shaped plates 12-50, then the telescopic ends of the second electric telescopic rods 12-52 are extended to the greatest extent, so that the two second arc-shaped plates 12-51 respectively prop against the inner walls of the two sides of the pipeline, and at the moment, a complete deformable circular ring 12-49 is formed between the two second arc-shaped plates 12-51 and the two second arc-shaped plates 12-51, and the process of enlarging the deformable circular ring 12-49 can be completed. At this time, the telescopic end of the electric telescopic rod 12-28 is retracted, the conical disc 12-24 is pulled to be inserted into the deformable circular ring 12-49, when the telescopic end of the electric telescopic rod 12-28 is retracted to the maximum extent, the baffle disc 12-25 on the side wall of the conical disc 12-24 can be attached to the side wall of the deformable circular ring 12-49, thus the conical disc 12-24 can block the inner ring cavity of the deformable circular ring 12-49, at this time, an independent sealed space is formed in the pipeline between the deformable circular ring 12-49 and the disc 12-1, at this time, the submersible pump 7 operates, the submersible pump 7 discharges the scale remover added in advance in the scale remover filtering box 4 into the cavity between the deformable circular ring 12-49 and the disc 12-1 sequentially through the connecting pipe 8, the first connecting hose 12-8 and the transverse pipe 12-6, until the scale remover fills the cavity between the deformable ring 12-49 and the disc 12-1, at this time, the scale remover reacts with the scale on the inner wall of the pipeline, so that the scale remover can effectively dissolve the scale on the inner wall of the pipeline between the deformable ring 12-49 and the disc 12-1, the first motor 12-17 operates in the process of flushing the scale remover, the first motor 12-17 drives the cylinder 12-20 to rotate through the gear 12-18 and the toothed ring 12-23 during operation, the stirring rod 12-21 and the stirring blades 12-22 are synchronously driven to rotate during rotation of the cylinder 12-20, and thus the stirring blades 12-22 stir the scale remover between the deformable ring 12-49 and the disc 12-1 to ensure that the scale remover is more fully contacted with the scale condensed on the inner wall of the pipeline, the water pump 9 starts to operate, the water pump 9 pumps the water scale scavenger between the deformable circular ring 12-49 and the circular disc 12-1 sequentially through the second L-shaped pipe 12-2 and the connecting hose 12-5 (the water scale scavenger is sucked from the groove 12-3 at the bottom of the second L-shaped pipe 12-2) and is discharged into the water scale scavenger filter tank 4 sequentially through the vertical pipe 10 and the first L-shaped pipe 11, and due to the arrangement of the pore plate 5 volume filter screen 6 in the water scale scavenger filter tank 4, the filter screen 6 can effectively intercept the doped water scale particles which are not completely dissolved in the water scale scavenger, thereby realizing the purification purpose of the water scale scavenger, and the filtered water scale scavenger can be reused to play the role of the water scale scavenger. The above process is the whole process of cleaning scale in a pipe by the scale cleaning mechanism 12 for a distance (a distance refers to scale between the deformable ring 12-49 and the disc 12-1).
After the scale between the deformable circular ring 12-49 and the disc 12-1 is cleaned, the volume deformation of the deformable circular ring 12-49 is controlled again to be reduced, then the motor 12-12 operates, the roller 12-13 drives the pipeline scale cleaning mechanism 12 to continue to move forward, the working process is repeated, the scale in the pipeline is cleaned gradually, and the cleaning of the scale in the whole pipeline is completed.
