nullAfter rotation spring 4 obtains power at rotation spring motor 6，Arrive again at boosting mechanism 7 after much enclosing around roller 5 Raohe，In these transmission ways，Due to factors such as frictional dissipations，Have kinetic equation loss，Therefore after arriving at boosting mechanism 7，The rotating speed of rotation spring 4 is certain to reduce，Fall flat，Therefore，At boosting mechanism 7, it is carried out reinforcing，Clamping sleeve 29 is locked and revolves spring 4，Compress tooth axle driving lever 32，Tooth axle driving lever 32 makes fixing tooth axle 31 drive tooth set 30 then to drive clamping sleeve 29 to be fastened together with rotation spring 4 by whole boosting mechanism，Tapering belt wheel 28 is connected to add force motor 39 by belt wheel and obtains power，Add force motor 39 rotating speed identical with rotation spring motor 6 rotating speed，Therefore tapering belt wheel 28 is herein，Can give and the power of rotation spring 4 one with rotation spring motor 6 same rotational speed，Therefore，Revolving spring 4 is made it identical with rotary speed when just going out to revolve spring motor 6 herein by reinforcing.

Control device 9 of retreating mainly realizes revolving feeding and the retrogressing of spring 4, it realizes mainly by the threaded engagement between direction of rotation and rotation spring 4 and upper spiral cover 33, the lower spiral cover 34 of rotation spring 4, the when of feeding, with spiral cover driving lever 35, upper spiral cover 33, lower spiral cover 34 are closed tightly, the structure being similar to worm and gear is formed with rotation spring 4, the most now going up spiral cover 33, lower spiral cover 34 motionless, along with the rotation of rotation spring 4, rotation spring 4 can constantly advance；When rotation spring 4 reversely rotates when, then can retreat.

Step 4: the bit of line shaft 24 end enters pipeline 23 for clearance and its inner-walls of duct carries out cutting cleaning.

Cutter head 22 is arranged on line shaft 24 end, rotation along with line shaft 24, cutter head 22 also can and then rotate, the dirt of duct wall is carried out cutting cleaning, along with being constantly fed motion, gradually clear up to the other end from one end of pipeline, during cleaning, water circulation system take the dirt impurity of cleaning out of pipeline 23 for clearance；Along with the continuous circulation of water, impact on impeller 21, impeller 21 can be promoted to rotate so that impeller 21 can rotate, by what the water pressure of water circulation system was cutter head 22, the power providing certain.

Step 5: water is pumped into pipeline 23 for clearance by the water pump of water circulation system to be increased power by water slug impeller and carry out the flushing of dirt impurity, and is carried out pumping by sewage draw-off pump at pipeline 23 port of export for clearance, and enters cistern filtering recirculation.

Water circulation system mainly has three effects, and one is to be rinsed the dirt impurity being cut mechanism's cutting in pipeline 23 to be cleaned, and two is to provide certain fine setting power for cutting mechanism, and three is for providing reacting cycle power when withdrawing.Water is released from water tank 16 by water pump 8 and is entered diversion box 10, open valve 13, enter and connect pipeline 27, being entered pipeline 23 for clearance by connecting pipeline 27, water is got on impeller 21, increases line shaft 24 power, dirt on cutter head 21 rotary cutting tube wall, form impurity, then by water, it is taken out of from the outlet of pipeline 23 for clearance, enter drainage 17.Drainage herein has pumping sewage pump, also rotary power and pipe drainage ability can be increased in outlet pumping, the sewage discharged is pumped into the impurity range of water tank 16 by pumping sewage pump through sewage pump outlet conduit 38, it is then passed through filtering, impurity stays impurity range, clear water can enter again clear water zone, water pump 8 carry out subsequent cycle.

In step 5, water circulation system is in the course of the work, and the pressure relief device of water circulation system is flowed to by pressure release cylinder pressure release and liquid and the 3rd valve size changes water pressure and then realizes power adjustment.Pressure relief device can play protection and regulation effect, diversion box 10 be connected pipeline 27, the connection pipeline of pipeline 23 for clearance outlet is respectively equipped with the first valve 13 and the second valve 15, second pressure relief device 12 is connected in pipeline with water tank 16 and is provided with the 3rd valve 14, pumping sewage pump 17 sets the 4th valve 18 in the connection pipeline of pipeline 23 for clearance outlet, flowed to and the 3rd valve opening size by the pressure release cylinder in pressure relief device or change liquid, voltage regulation result can be realized, speed of removing contamination can be controlled by pressure regulation, again amplify scrubbing power, and the dirt cut is gone out pipeline.

Step 6: after having cut, is carried out reacting cycle by water circulation system, and is rotated backward by the motor of line shaft motor 3, rotation spring motor 6 and roller 5, by the effect controlling device 9 of retreating, makes line shaft 24 and rotation spring 4 exit rapidly pipeline 23 for clearance.

Utilize the effect of diversion box 10, shown in Fig. 1, the when of cutting, opening the first valve the 13, the 3rd valve the 14, the 4th valve 18, close the second valve 15, water is released from water tank 16 by water pump 8 and is entered diversion box 10, then pipeline 23 for clearance is entered by connection pipeline 27, by dirt impurity after pipeline 23 for clearance brings out, drainage 17 impurity range entering water tank 16 filters, and then clear water entrance clear water zone carries out subsequent cycle；After having cut, close the first valve the 13, the 4th valve 18, open the 3rd valve the 14, second valve 15, water is released from water tank 16 by water pump 8 and is entered diversion box 10, is then passed through the second valve 15 and is entered pipeline by the outlet of pipeline 23 for clearance, cutting mechanism is played repulsion, it is made to exit rapidly pipeline 23 for clearance, then water enters pressure relief device, the impurity range of the second valve 15 reflow tank 16 again filter, and clear water enters clear water zone and again circulates.

This structure makes the cutting water for cleaning in this utility model to recycle, and does not have sewage and discharges, energy-saving and environment-friendly.

In sum, the actuating unit of this pipeline cleaning that this utility model provides and method, utilize the effect of belt wheel and conveyer belt, make the coaxial output of line shaft and rotation two power of spring, rotation spring and the transmission of line shaft coaxial power, make rotation spring outside possess flexible, advance, guide, anti-attrition, the function of anti-twisting, it is achieved provide stable power to the cutting apparatus rotated, and power can arbitrarily adjust.

Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, within the every and same or analogous design of this utility model belongs to protection domain of the present utility model.
