step one: the power motor is started, the power shaft motor 3 and the rotary spring motor 6 respectively supply power to the power shaft 24 and the rotary spring 4, and the coaxial same-direction different-speed rotary power output of the power shaft 24 and the rotary spring 4 is realized through the axle spring differential mechanism 45, and the specific structure is as shown in the embodiment 7.
Step two: the power shaft 24 and the rotary spring 4 are wound on the roller 5, and the power transmission direction of the power shaft 24 and the rotary spring 4 is changed through the roller wheel supporting bracket 25 and the roller wheel 26 on the roller 5 so as to move along the control mechanism.
The concentric power shaft 24 and the spiral spring 4 transmitted by the power end need to rely on a transmission mechanism for power transmission, and the power transmission is mainly embodied on the spiral spring support 2 of the power shaft 24 and the spiral spring 4 which are wound on the roller 5, and the specific structure of the spiral spring support 2 is as follows: a rolling wheel support bracket 25 is arranged on the rolling surface of the roller 5 along the axial direction of the roller 5, and a rolling wheel 26 for supporting a cutting mechanism disc on the roller 5 is arranged on the rolling wheel support bracket 25. The plurality of rolling wheels 26 form a thread-like structure on the rolling surface of the roller 5, and the spiral spring 4 is wound around the locus of the rolling wheels 26 on the rolling surface of the roller 5 and finally transferred to the cutting advance and retreat control mechanism.
Step three: the power shaft 24 and the rotary spring 4 sequentially pass through the force application mechanism 7 and the advance and retreat control device 9, the force application mechanism 7 compensates the kinetic energy of the rotary spring, and the advance and retreat control device 9 realizes the advance and retreat function by utilizing the thread and the rotation direction change of the rotary spring 4.
After the spiral spring 4 gets power from the spiral spring motor 6, the spiral spring is wound around the roller 5 for many circles and then goes to the stress application mechanism 7, in the transmission process, due to factors such as friction loss, the power loss exists, therefore, after reaching the stress application mechanism 7, the rotating speed of the spiral spring 4 is certainly reduced, the expected effect cannot be achieved, therefore, stress is applied to the spiral spring at the stress application mechanism 7, the pressing sleeve 29 is sleeved on the spiral spring 4, the tooth shaft deflector rod 32 is pressed, the tooth shaft deflector rod 32 enables the fixed tooth shaft 31 to drive the tooth sleeve 30 to drive the pressing sleeve 29 to fasten the whole stress application mechanism and the spiral spring 4 into a whole, the taper pulley 28 is connected with the stress application motor 39 through the pulley to obtain power, the rotating speed of the stress application motor 39 is the same as that of the spiral spring motor 6, and therefore, the taper pulley 28 can give the power at the same rotating speed as that of the spiral spring motor 6 to the spiral spring 4 is stressed at the place, so that the rotating speed of the spiral spring 4 is the same as that just exits the spiral spring motor 6.
The advance and retreat control device 9 mainly realizes the feeding and retreating of the spiral spring 4, mainly by the rotation direction of the spiral spring 4 and the screw thread matching between the spiral spring 4 and the upper spiral gland 33 and the lower spiral gland 34, when in feeding, the upper spiral gland 33 and the lower spiral gland 34 are tightly combined by the spiral gland deflector rod 35, and a structure similar to a worm gear and a worm is formed with the spiral spring 4, at the moment, the upper spiral gland 33 and the lower spiral gland 34 are not moved, and the spiral spring 4 continuously advances along with the rotation of the spiral spring 4; when the rotary spring 4 rotates reversely, the rotary spring retreats.

The tool bit 22 is arranged at the tail end of the power shaft 24, the tool bit 22 rotates along with the rotation of the power shaft 24 to cut and clean dirt on the wall of the pipeline, and the cleaned dirt and impurities are carried out of the pipeline 23 to be cleaned by the water circulation system in the cleaning process along with continuous feeding movement from one end of the pipeline to the other end of the pipeline; along with the continuous circulation of the water, the water impacts on the impeller 21 and pushes the impeller 21 to rotate, so that the impeller 21 can provide a certain power for the rotation of the cutter head 22 through the water pressure of the water circulation system.
Step five: the water pump of the water circulation system pumps water into the pipeline 23 to be cleaned, increases power and washes dirt and impurities through the water impact impeller, pumps the dirt and impurities at the outlet end of the pipeline 23 to be cleaned through the sewage pump, and discharges the dirt and impurities into a water tank for filtering and recycling.
The water circulation system mainly has three functions, namely flushing dirt and impurities cut by the cutting mechanism in the pipeline 23 to be cleaned, providing certain fine adjustment power for the cutting mechanism, and providing reverse circulation power for tool withdrawal. Water is pumped out of the water tank 16 by the water pump 8 and enters the water diversion tank 10, the first valve 13 is opened, the water enters the connecting pipeline 27, the water enters the pipeline to be cleaned 23 through the connecting pipeline 27, the water is beaten onto the impeller 21, the power of the power shaft 24 is increased, the cutter head 22 rotates to cut dirt on the pipe wall to form impurities, and then the impurities are brought out of the outlet of the pipeline to be cleaned 23 through the water and enter the sewage disposal system 17. The sewage system is provided with a swabbing sewage pump, the rotary power and the pipeline drainage capacity can be increased by swabbing at the outlet, the discharged sewage is pumped into an impurity area of the water tank 16 by the swabbing sewage pump through a sewage pump outlet pipeline 38, then filtered, impurities are remained in the impurity area, clean water enters a clean water area again, and the water pump 8 carries out the next circulation.
In the fifth step, the water circulation system is in the working process, the pressure relief and pressure regulation device of the water circulation system is used for relieving pressure through the pressure relief cylinder, and the liquid flow direction and the size of the third valve change the water pressure so as to realize power regulation.

Step six: after cutting, the water circulation system carries out reverse circulation, and the motors of the power shaft motor 3, the rotary spring motor 6 and the roller 5 are reversely rotated, so that the power shaft 24 and the rotary spring 4 are rapidly withdrawn from the pipeline 23 to be cleaned under the action of the advance and retreat control device 9.
By utilizing the function of the water diversion tank 10, and combining with the function shown in fig. 1, when cutting, the first valve 13, the third valve 14 and the fourth valve 18 are opened, the second valve 15 is closed, water is pumped out of the water tank 16 by the water pump 8 and enters the water diversion tank 10, then enters the pipeline 23 to be cleaned through the connecting pipeline 27, dirt and impurities are carried out from the pipeline 23 to be cleaned, filtered by the impurity area of the water tank 16 through the sewage disposal system 17, and then clear water enters the clear water area for the next circulation; after cutting is finished, the first valve 13 and the fourth valve 18 are closed, the third valve 14 and the second valve 15 are opened, water is pumped out of the water tank 16 by the water pump 8 and enters the water diversion tank 10, then enters the pipeline from the outlet of the pipeline to be cleaned 23 through the second valve 15, the reverse pushing effect is achieved on the cutting mechanism, the cutting mechanism rapidly exits the pipeline to be cleaned 23, then the water enters the pressure relief and pressure regulation device, the water flows back to the impurity region of the water tank 16 again to be filtered by the second valve 15, and the clean water enters the clean water region to be recycled.
