The concentric line shaft 24 and rotation spring 4 that power end is passed over are transmitted, it is necessary to enter action edge by transmission mechanism, be mainly reflected in line shaft 24 and rotation spring 4 is so wound on the rotation spring bracket 2 on roller 5, the concrete structure of spring bracket 2 is revolved herein is：The rolling wheel support 25 along the axial direction of roller 5 is disposed with the rolling surface of roller 5, the scroll wheel 26 being installed with wheel support 25 for supporting cutting mechanism disk on roller 5 is rolled.Multiple scroll wheels 26 form the structure similar to screw thread on the rolling surface of roller 5, and the track pitch of the laps of scroll wheel 26 of the rotation spring 4 on the rolling surface of roller 5 is finally resent to cutting advance and retreat controlling organization.
Step 3：Line shaft 24 and rotation spring 4 pass sequentially through boosting mechanism 7 and advance and retreat control device 9, and boosting mechanism 7 carries out kinetic energy to it and made up, and advance and retreat control device 9 realizes advance and retreat function using screw thread and the rotation direction conversion for revolving spring 4.
Rotation spring 4 is obtained after power at rotation spring motor 6, arrived again at boosting mechanism 7 after the Raohe of roller 5 much circle, in these transmission ways, due to factors such as frictional dissipations, have kinetic equation loss, therefore after reaching at boosting mechanism 7, the rotating speed of rotation spring 4 is certain to reduction, fall flat, therefore, it is reinforced at boosting mechanism 7, clamping sleeve 29, which is locked, revolves spring 4, compress tooth axle driving lever 32, tooth axle driving lever 32 causes fixing tooth axle 31 to drive tooth set 30 then to drive clamping sleeve 29 to be fastened together whole boosting mechanism with rotation spring 4, taper belt wheel 28 is connected to reinforcing motor 39 by belt wheel and obtains power, reinforce the rotating speed of motor 39 identical with the rotation rotating speed of spring motor 6, therefore taper belt wheel 28 is here, power of the rotation spring 4 one with revolving the same rotational speed of spring motor 6 can be given, therefore, rotation spring 4 make it that it is identical with rotary speed when just going out to revolve spring motor 6 by reinforcing here.
Advance and retreat control device 9 mainly realizes the feeding and retrogressing of rotation spring 4, it coordinates mainly by the screw thread between the direction of rotation of rotation spring 4 and rotation spring 4 and upper spiral cover 33, lower spiral cover 34 realizes, when feeding, upper spiral cover 33, lower spiral cover 34 are closed tightly with spiral cover driving lever 35, with structure of rotation spring 4 formation similar to worm and gear, then now upper spiral cover 33, lower spiral cover 34 are motionless, with the rotation of rotation spring 4, and rotation spring 4 can constantly advance；When the reverse rotation of spring 4 is revolved, then it can retreat.
Step 4：The cutting head of the end of line shaft 24 enters pipeline 23 for clearance and carries out cutting cleaning to its inner-walls of duct.
Cutter head 22 is arranged on the end of line shaft 24, with the rotation of line shaft 24, cutter head 22 also can and then rotate, cutting cleaning is carried out to the dirt of duct wall, with being constantly fed motion, gradually cleared up to the other end from one end of pipeline, during cleaning, the dirt impurity of cleaning is taken out of pipeline 23 for clearance by water circulation system；With the continuous circulation of dampening, impact on impeller 21, impeller 21 can be promoted to rotate so that impeller 21 for the rotation of cutter head 22 can provide certain power by the water pressure of water circulation system.
Step 5：Water is pumped into pipeline 23 for clearance by the water pump of water circulation system increases the flushing of power and progress dirt impurity by water slug impeller, and carries out pumping in the port of export of pipeline 23 for clearance by sewage draw-off pump, and is discharged into cistern filtering recycling.
Water circulation system mainly has three effects, and one is that the dirt impurity that mechanism cutting is cut in pipeline to be cleaned 23 is rinsed, and two be that certain fine setting power is provided for cutting mechanism, and three provide reacting cycle power when being for withdrawing.Water is released into diversion box 10 by water pump 8 from water tank 16, open valve 13, into connecting pipe 27, pipeline 23 for clearance is entered by connecting pipe 27, water is got on impeller 21, increase the power of line shaft 24, dirt on the rotary cutting tube wall of cutter head 21, impurity is formed, is then taken out of the outlet of its from pipeline 23 for clearance by water, into drainage 17.There is pumping sewage pump in drainage herein, it can also increase rotary power and pipe drainage ability in outlet pumping, the sewage of discharge is pumped into the impurity range of water tank 16 by pumping sewage pump by sewage pump outlet conduit 38, then by filtering, impurity stays in impurity range, clear water can enter clear water zone again, and subsequent cycle is carried out by water pump 8.
In the course of the work, the pressure relief device of water circulation system changes water pressure by pressure release cylinder pressure release and liquid flow direction and the 3rd valve size and then realizes power adjustment water circulation system in step 5.Pressure relief device can play protection and adjustment effect, in diversion box 10 and connecting pipe 27, the first valve 13 and the second valve 15 are respectively equipped with the connecting pipeline that pipeline 23 for clearance is exported, second pressure relief device 12 is with being provided with the 3rd valve 14 in the connecting pipeline of water tank 16, the 4th valve 18 is set in the connecting pipeline that pumping sewage pump 17 is exported with pipeline 23 for clearance, pass through the pressure release cylinder or change liquid flow direction and the 3rd valve opening size in pressure relief device, voltage regulation result can be realized, pass through the controllable speed of removing contamination of pressure regulation, amplification decontaminates power again, and the dirt cut is gone out pipeline.
Step 6：After the completion of cutting, reacting cycle is carried out by water circulation system, and the motor of power spindle motor 3, rotation spring motor 6 and roller 5 is rotated backward, by the effect of advance and retreat control device 9, makes line shaft 24 and rotation spring 4 exit pipeline 23 for clearance rapidly.
Utilize the effect of diversion box 10, with reference to shown in Fig. 1, when cutting, the first valve 13, the 3rd valve 14, the 4th valve 18 are opened, the second valve 15 is closed, water is released into diversion box 10 by water pump 8 from water tank 16, then pipeline 23 for clearance is entered by connecting pipe 27, by dirt impurity after pipeline 23 for clearance is brought out, the impurity range for entering water tank 16 by drainage 17 is filtered, and then clear water enters clear water zone progress subsequent cycle；After the completion of cutting, close the first valve 13, the 4th valve 18, open the 3rd valve 14, the second valve 15, water is released into diversion box 10 by water pump 8 from water tank 16, then enters pipeline by the outlet of pipeline 23 for clearance by the second valve 15, repulsion is played to cutting mechanism, it is set to exit pipeline 23 for clearance rapidly, then water enters pressure relief device, is filtered by the impurity range of the second valve 15 reflow tank 16 again, clear water circulated again into clear water zone.
This structure enables the cutting water for cleaning in the present invention to recycle, and sewage discharge is not had, energy-saving and environment-friendly.
In summary, the actuating unit and method for this pipeline cleaning that the present invention is provided, utilize the effect of belt wheel and conveyer belt, so that the coaxial output of line shaft and rotation two power of spring, revolve spring and the transmission of line shaft coaxial power, so that rotation spring outside possesses flexible, propulsion, guiding, anti-attrition, the function of anti-twisting, realize that the cutting apparatus to rotation provides stable power, and power can be adjusted arbitrarily.
Exemplified as above is only that the same or analogous design of the every and present invention is belonged within protection scope of the present invention for example, not constituting the limitation to protection scope of the present invention to of the invention.
