The second swing arms 25 can be driven to tilt and swing outward along the second ear seat 19 through the parallel links 27, and the first rollers 24 and the second rollers 26 are synchronously driven to press against the inner wall of the clogged pipe. A threaded barrel 22 is fixedly provided in the middle of the hexagonal sliding disk 13, and a screw 21 with a thread passing through is inserted inside the threaded barrel 22. Under the spiral action of the screw 21 and the threaded barrel 22, the hexagonal sliding disk 13 can be driven to slide along the I-shaped slide rail 15 toward the hexagonal center disk 16. A first square through hole is opened in the middle of the first hexagonal disk 11, and a first motor 2 with an output end facing inward is installed inside the first square through hole. The motor shaft end of the first motor 2 is fixedly connected to the left end of the screw 21, and the motor shaft of the first motor 2 can drive the screw 21 to rotate synchronously, and the right end of the screw 21 is rotatably inserted in the middle of the hexagonal center disk 16; By adjusting the tilt swing amplitude of the first swing arm 23 and the second swing arm 25 on the hexagonal cylinder 1, the first roller 24 and the second roller 26 are made to abut against the inner wall of the dredging pipe, so as to adapt to pipes of different sizes and move inward along the inner wall of the pipe to ensure the stable movement of the dredging device inside the pipe. Since the rollers are in close contact with the inner wall of the pipe, a stable supporting force is provided for the device, so that the device can maintain balance during the dredging process.

A concentrically fixed planetary gear 45 is sleeved on the inner end of each planetary shaft 44. Each planetary gear 45 is meshed with the gear disk 43. The planetary gears 45 on the planetary shaft 44 can mesh and rotate along the gear disk 43, and drive the planetary shaft 44 and the first reamer 46 to perform planetary rotation. A fixed shaft 35 is fixedly provided in the middle of the concentric disk 33, and a concentrically fixed conical column 36 is sleeved on the outer end of the fixed shaft 35. A conical spiral blade 37 is fixedly provided on the outer surface of the conical column 36.

These first reamers 46 rotate around the conical column 36, just like planets revolve around the sun. Their rotation direction and speed can be designed according to actual conditions; the first reamers 46 can penetrate into the gaps and corners of the inner wall of the pipe and scrape off the sludge attached to the pipe wall.

[0022] Embodiment 4: Based on Embodiment 3, this embodiment also includes the following contents: like Figure 7 and Figure 8 As shown, the right side of the circular fixed plate 3 is fixed with a concentrically distributed gear ring 5, and the inner section of each planetary slide 52 is sleeved with a concentrically fixed widening gear 56, each widening gear 56 is meshed with the gear ring 5, and the teeth of the widening gear 56 are slidably connected with the teeth of the gear ring 5 along the axis direction of the widening gear 56, and the widening gear 56 on the planetary slide 52 can mesh and rotate along the gear ring 5, and drive the planetary slide 52 and the second reamer 57 to perform planetary rotation; A pair of concentrically fixed limit plates 41 are sleeved in the middle of the fixed sleeve 4, and an annular wave groove 42 is provided on the opposite surfaces of the pair of limit plates 41. An I-shaped shaft 53 is fixed to the inner end of each planetary slide 52, and a rectangular sleeve 54 is rotatably sleeved in the middle of each I-shaped shaft 53.

The rectangular sleeve 54 is located between the pair of limiting plates 41 and is slidably connected to the opposite surfaces of the pair of limiting plates 41. A pair of limiting pins 55 are fixedly disposed on the two side surfaces of the rectangular sleeve 54. The outer ends of the pair of limiting pins 55 are respectively slidably engaged in the annular wave groove 42 on the same side. Under the limiting effect formed by the limiting pins 55 and the annular wave groove 42, the rectangular sleeve 54 and the I-shaped shaft 53 can be driven to slide along the annular wave groove 42. When the second reamer 57 performs planetary rotation, it can perform circular motion around the hollow drum 31, so that the second reamer 57 can clean an annular area on the inner wall of the pipe with the hollow drum 31 as the center; through the planetary rotation, the second reamer 57 can penetrate into every corner of the annular area, thereby effectively removing stubborn stains attached to the pipe wall and avoiding the occurrence of dredging dead corners; The second reamer 57 can slide back and forth, which makes its cleaning range not limited to an annular area. During the sliding process, the second reamer 57 can move along the axial direction of the pipe, so as to cover different positions of the inner wall of the pipe. Combined with the planetary rotation, the cleaning trajectory of the second reamer 57 changes from a simple ring to a spiral shape, which greatly increases the coverage of dredging.

[0023] Specifically, the working principle and operation method of the present invention are as follows: Step 1: When desilting a blocked pipe, place the hexagonal cylinder 1 and the hollow rotating cylinder 31 in one end of the blocked pipe, and make the conical column 36 and the conical spiral blade 37 face the blocked part of the blocked pipe; Step 2: Under the driving action of the first motor 2, the motor shaft of the first motor 2 drives the lead screw 21 to rotate synchronously, and under the spiral action of the lead screw 21 and the threaded cylinder 22, the hexagonal sliding disk 13 is driven to slide along the I-shaped slide rail 15 toward the hexagonal center disk 16; Step 3: Under the hinged action of the hinged link 28, the first swing arm 23 is driven to swing outward along the first ear seat 17, and the second swing arm 25 is driven to swing outward along the second ear seat 19 through the parallel link 27, and the first roller 24 and the second roller 26 are simultaneously driven to abut against the inner wall of the clogged pipe; Step 4: Under the driving action of the second motor 34, the motor shaft of the second motor 34 drives the fixed shaft 35, the concentric disk 33, the tapered column 36, and the tapered spiral blade 37 to rotate, and synchronously drives the hollow drum 31 and the annular rail 32 to rotate along the annular groove; Step 5: the planetary shaft 44 and the first reamer 46 on the concentric disk 33 revolve along with the concentric disk 33, and the planetary gear 45 on the planetary shaft 44 rotates along the gear disk 43, and drives the planetary shaft 44 and the first reamer 46 to perform planetary rotation; Step 6: The planetary slide bar 52 and the second reamer 57 on the hollow drum 31 revolve along with the hollow drum 31, and the widened gear 56 on the planetary slide bar 52 rotates along the gear ring 5, and drives the planetary slide bar 52 and the second reamer 57 to perform planetary rotation; The I-shaped shaft 53 on the planetary slide bar 52 drives the rectangular sleeve 54 to revolve along the pair of limit plates 41, and under the limiting action formed by the limit pin 55 and the annular wave groove 42, drives the rectangular sleeve 54 and the I-shaped shaft 53 to slide along the annular wave groove 42, and synchronously drives the planetary slide bar 52 and the second reamer 57 to reciprocate along the fixed ring 51; Step seven, the hexagonal cylinder 1 and the hollow rotating cylinder 31 are pushed inward along the blocked pipe, driving the first roller 24 and the second roller 26 to roll inward along the inner wall of the blocked pipe, and the blocked part of the blocked pipe is broken by the conical column 36 and the conical spiral blade 37. Under the joint action of the first reamer 46 and the second reamer 57, the blocked part of the blocked pipe is completely broken, thereby clearing the blocked pipe and finally completing the dredging operation of the blocked pipe.

[0024] When the present invention is used for pipeline dredging, the hexagonal cylinder 1 and the roller can adapt to different pipe diameters, move stably and reduce damage; the combination of the conical column 36, the conical spiral blade 37, the first reamer 46 and the like can efficiently dredge and achieve comprehensive dredging without dead angles; the planetary rotation and reciprocating sliding of the second reamer 57 are combined to expand the dredging range, enhance adaptability and flexibility, and improve the dredging depth and quality; the entire device is easy to operate, improves the dredging efficiency, and has low labor costs.
