The specific dredging process of the steps (1) to (3) in the invention comprises the following steps: before dredging the sewer or the toilet, the dredging steel wire 28 is taken out and penetrates forwards from the rear end of the hollow worm 12, passes between the upper wire feeding wheel 23 and the lower wire feeding wheel 24 and then extends forwards through the hollow shaft 5. Then a spanner is used for screwing a compression nut 37, the compression nut 37 reduces the distance between the upper pressure seat 34 and the lower pressure seat 35, the upper supporting plate 30 slightly rotates downwards by taking the first upper rotating shaft 13 as a center, and the lower supporting plate 31 slightly rotates upwards by taking the second upper rotating shaft 15 as a center, so that the upper wire feeding wheel 23 and the lower wire feeding wheel 24 can compress the dredging steel wire 28 to provide enough friction force for conveying the dredging steel wire 28 forwards, the upper driving gear 19 can be ensured to be always meshed with the upper driven gear 21, and the lower driving gear is always meshed with the lower driven gear.
Then an operator holds the handle shell 40 with one hand, the front end of the hollow shaft 5 faces a sewer pipe opening or a toilet opening, the linear switch 42 is pressed down to start the speed reducing motor 39, the outer hexagonal column 29 drives the inner hexagonal driving sleeve 9 to rotate, the first driving gear 10 on the inner hexagonal driving sleeve 9 drives the first driven gear 11 to rotate, the first driven gear 11 drives the hollow worm 12 to rotate, the upper worm gear 17 and the lower worm gear 18 which are meshed with the front end part of the hollow worm 12 rotate, the upper driving gear 19 which is coaxial with the upper worm gear 17 and the lower driving gear which is coaxial with the lower worm gear 18 also synchronously rotate, the upper driving gear 19 drives the upper driven gear 21 to rotate, the lower driving gear drives the lower driven gear to rotate, the upper wire feeding wheel 23 which is coaxial with the upper driving gear 19 rotates, the lower wire feeding wheel 24 which is coaxial with the lower driving gear rotates, the upper wire feeding wheel 23 and the lower wire feeding wheel 24 jointly drive the dredging, the front end of the dredging steel wire 28 extends into the blocked sewer pipe or the toilet. When resistance is generated in the forward movement process of the dredging steel wire 28, the pressing cap 49 on the top of the front side of the handle shell 40 is pressed, the driving rod 47 moves downwards along the mounting pipe 43 by overcoming the elastic force of the spring 48, the front rack 50 on the rear side of the driving rod 47 moves downwards, the front rack 50 drives the rear rack 51 to move upwards through the rotation limiting gear 45, the rear rack 51 drives the limiting rod 46 to move upwards along the guide pipe 44 until the lower end of the limiting rod 46 is separated from the positioning groove 57 on the top of the brake disc 8, and the state that the pressing cap 49 is pressed is maintained. Because the front side wall of the mounting shell 7 is rotationally connected to the hollow shaft 5, the rear side wall of the mounting shell 7 is rotationally connected to the hollow worm 12, after the brake disc 8 is liberated, the hollow worm 12 drives a part of power of the upper worm wheel 17 and the lower worm wheel 18 to drive the mounting shell 7 to rotate, the rotation of the mounting shell 7 drives the dredging steel wire 28 to rotate, and due to the arrangement of the rotary damper 6, the rotation speed of the mounting shell 7 and the brake disc 8 is relatively low, so that the hollow worm 12 can continuously transmit a part of power to the upper worm wheel 17 and the lower worm wheel 18, the dredging steel wire 28 is continuously moved forwards, the speed of forward movement is reduced, and the dredging steel wire 28 can be driven to rotate while moving forwards, and the front end of the dredging steel wire 28 can easily penetrate through the blocking section. After passing through the blocking section, the reversing switch 52 on the side part of the handle shell 40 is pressed, the speed reducing motor 39 rotates reversely, the dredging steel wire 28 is driven to rotate reversely and move backwards at the same time, and therefore the dredging steel wire 28 can rotate and move forwards and backwards in the blocking section, and meanwhile, water is flushed into the sewer pipeline or the toilet, and the blocking section in the sewer pipeline or the toilet can be dredged by repeatedly flushing.
When the dredging operation is finished, the pressing cap 49 is loosened, the driving rod 47 moves upwards along the mounting pipe 43 under the action of the spring 48, the front rack 50 drives the rear rack 51 and the limiting rod 46 to move downwards through the limiting gear 45 to press against a positioning groove 57 at the top of the brake disc 8, the brake disc 8 is locked, the mounting shell 7 cannot rotate, then the reversing switch 52 at the side part of the handle shell 40 is pressed, the speed reducing motor 39 rotates reversely, the dredging steel wire 28 is driven to move backwards to be withdrawn from a pipeline or a toilet, and during the withdrawing process of the dredging steel wire 28, a towel is used at the front side of the hollow shaft 5 to firstly remove dirt liquid or attached dirt carried on the dredging steel wire 28. When the dredging steel wire 28 can be pulled, the speed reducing motor 39 is turned off, and the dredging steel wire 28 is pulled backwards out of the pipeline or the closestool by direct force.
Of course, during dredging operation, the pressing cap 49 is pressed down while the speed reducing motor 39 is started, the brake disc 8 is released, the mounting shell 7 always keeps rotating, and meanwhile, the dredging steel wire 28 also moves forwards under the clamping of the upper wire feeding wheel 23 and the lower wire feeding wheel 24, so that the dredging mode is good in penetrability and trafficability, and long in dredging time.
The hollow shaft 5 not only plays a role of guiding the dredging steel wire 28 forwards, but also the hollow shaft 5 is used for being rotatably connected with the mounting shell 7 through a fourth bearing 33; the hollow worm 12 not only functions to reduce the rotational speed of the reduction motor 39 by an increased torque, but also functions to guide the dredging wire 28 forward and to rotatably connect the mounting case 7 through the third bearing 32.
The rotary damper 6 damps the rotation of the brake disc 8 by adopting damping oil, so that the power of the hollow worm 12 can drive the dredging steel wire 28 to move forward and drive the dredging steel wire 28 to rotate.
The left side and the right side of the front mounting plate 1, the rear mounting plate 2, the top plate 3, the handle case 40 and the driving box 38 are respectively of an integral structure and are connected through connecting bolts. This facilitates the opening of the vertical grooves and the installation of the first driving gear 10 and the first driven gear 11.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
