[0022] The present invention also provides a dredging method for the water conservancy project dredging device. Using the above water conservancy project dredging device, it includes the following steps:

[0023] Step 1, when dredging the blocked pipeline, place the hexagonal cylinder and the hollow rotating cylinder at one port of the blocked pipeline, so that the tapered column and the tapered spiral blade face the blocked part of the blocked pipeline;

[0024] Step 2, under the driving action of the first motor, the motor shaft of the first motor drives the lead screw to rotate synchronously. Under the spiral action of the lead screw and the threaded cylinder, drive the hexagonal sliding disk to slide towards the hexagonal center disk along the I-shaped slide rail;

[0025] Step 3, under the hinge action of the hinge connecting rod, drive the first swing arm to swing outwards obliquely along the first ear seat, and drive the second swing arm to swing outwards obliquely along the second ear seat through the parallel connecting rod, and synchronously drive the first roller and the second roller to both abut against the inner wall of the blocked pipeline;

[0026] Step Four, under the driving action of the second motor, the motor shaft of the second motor drives the fixed shaft, concentric disk, conical column, and conical spiral blade to rotate, and simultaneously drives the hollow rotating cylinder and the annular rail to rotate along the annular slot;

[0027] Step Five, the planetary shafts and the first reamer on the concentric disk revolve with the concentric disk, and the planetary gears on the planetary shafts mesh and rotate along the gear disk, driving the planetary shafts and the first reamer to perform planetary rotation;

[0028] Step Six, the planetary slide bars and the second reamer on the hollow rotating cylinder revolve with the hollow rotating cylinder, and the widened gears on the planetary slide bars mesh and rotate along the gear ring, driving the planetary slide bars and the second reamer to perform planetary rotation;

[0029] The I-shaped shaft on the planetary slide bar drives the rectangular sleeve to revolve along a pair of limit disks. Under the limiting action formed by the limit pin shaft and the annular wavy groove, the rectangular sleeve and the I-shaped shaft are driven to slide along the annular wavy groove, and simultaneously drive the planetary slide bar and the second reamer to slide reciprocally along the fixed ring;

[0030] Step Seven, push the hexagonal cylinder and the hollow rotating cylinder into the blocked pipeline, drive the first roller and the second roller to roll inward along the inner wall of the blocked pipeline, and crush the blocked part of the blocked pipeline through the conical column and the conical spiral blade. Under the combined action of the first reamer and the second reamer, the blocked part of the blocked pipeline is completely broken, thereby dredging the blocked pipeline and finally completing the dredging operation of the blocked pipeline.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, the rollers on the hexagonal cylinder can be adjusted according to the actual diameter of the pipeline, and the inner wall of the pipeline can be closely fitted by the expansion and contraction of the rollers, effectively solving the problem that traditional dredging equipment cannot be applied to different pipe diameters, and greatly improving the versatility and flexibility of the device;

[0033] The rollers are in contact with the inner wall of the pipeline. Compared with some dredging equipment with rigid contact, it can reduce the damage to the inner wall of the pipeline, and can perform all-round dredging operations on the entire inner wall of the pipeline, improving the dredging quality; moreover, through the movement of the rollers, the operation is simple, the dredging efficiency of the device is improved, and the labor cost is low;

[0034] 2. In the present invention, the combination of the conical column, the conical spiral blade and the first reamer forms a three-dimensional dredging system. The conical column performs the main sludge crushing and propulsion at the central position, the conical spiral blade conveys the sludge around, and the first reamer is responsible for cleaning the sludge near the pipe wall;

[0035] This multi-dimensional dredging method can cover all areas inside the pipeline. Whether it is a large amount of silt in the center of the pipeline or a small amount of stubborn silt attached to the pipe wall, it can be effectively cleaned, avoiding omissions during the dredging process, reducing the possibility of blockage, and further improving the dredging quality;

[0036] 3. In the present invention, the second reamer can rotate in a planetary motion and reciprocate, enabling it to better adapt to complex pipeline conditions. The second reamer can flexibly dredge along the pipe wall by adjusting its planetary rotation and sliding methods to ensure smooth passage and effective cleaning;

[0037] Due to the dual motion mode of the second reamer, which can cover most areas of the inner wall of the pipeline and can flexibly adjust its motion state as needed, it can deeply clean the inner wall of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

A penetratingly distributed second connecting shaft is rotatably inserted inside each second sleeve. Concentrically fixedly connected second rollers 26 are sleeved at both ends of each second connecting shaft. The first rollers 24 and the second rollers 26 can roll inward along the inner wall of the blocked pipeline.

[0057] Embodiment 2: On the basis of Embodiment 1, this embodiment further includes the following content:

[0058] As Figure 3 and Figure 4 shown, a hexagonal sliding disk 13 is slidably arranged on the left side inside the hexagonal cylinder 1. Three uniformly distributed T-shaped sliding grooves are formed on the outer side edge of the hexagonal sliding disk 13. An I-shaped sliding rail 15 is slidably engaged inside each T-shaped sliding groove. Each I-shaped sliding rail 15 is fixedly connected to the inner side wall of the hexagonal cylinder 1. Three uniformly distributed third trapezoidal notches are formed on the outer side edge of the hexagonal sliding disk 13, and the three third trapezoidal notches and the three T-shaped sliding grooves are alternately distributed. A T-shaped ear seat 14 is fixedly arranged inside each third trapezoidal notch.

[0059] An outer end of each T-shaped ear seat 14 is hinged with a pair of hinged connecting rods 28. An outer end of each pair of hinged connecting rods 28 penetrates through a corresponding first rectangular through hole and is movably hinged with a pair of first swing arms 23 on the same side. Under the hinging action of the hinged connecting rods 28, the first swing arms 23 can be driven to swing outwardly along the first ear seat 17. Parallel connecting rods 27 are coaxially hinged at the hinged joints of the pair of hinged connecting rods 28 and the pair of first swing arms 23. A right end of each parallel connecting rod 27 is movably hinged with a pair of second swing arms 25 on the same side. The parallel connecting rods 27 can drive the second swing arms 25 to swing outwardly along the second ear seat 19, synchronously driving the first rollers 24 and the second rollers 26 to abut against the inner wall of the silted pipeline.

[0060] A threaded cylinder 22 with a penetrating distribution is fixedly arranged in the middle of a hexagonal sliding disk 13. A lead screw 21 with a threaded penetration is inserted into the threaded cylinder 22. Under the spiral action of the lead screw 21 and the threaded cylinder 22, the hexagonal sliding disk 13 can be driven to slide along the I-shaped slide rail 15 towards the hexagonal center disk 16. A first square through hole is formed in the middle of the first hexagonal disk 11. A first motor 2 with an output end facing inwards is installed inside the first square through hole. An end of the motor shaft of the first motor 2 is fixedly connected to the left end of the lead screw 21. The motor shaft of the first motor 2 can drive the lead screw 21 to rotate synchronously, and the right end of the lead screw 21 is rotatably inserted into the middle of the hexagonal center disk 16.

[0061] By adjusting the tilting swing amplitudes of the first swing arms 23 and the second swing arms 25 on the hexagonal cylinder 1, the first rollers 24 and the second rollers 26 are abutted against the inner wall of the dredging pipeline, enabling adaptation to pipelines of different sizes. Moving inwards along the inner wall of the pipeline ensures the stable progress of the dredging device inside the pipeline. Since the rollers are in close contact with the inner wall of the pipeline, a stable supporting force is provided for the device, enabling the device to maintain balance during the dredging process.

[0062] Embodiment 3: On the basis of Embodiment 2, this embodiment further includes the following content:

[0063] As Figure 6 and Figure 7 shown, a fixedly arranged through sleeve 4 is fixedly arranged in the middle of the right side surface of the circular fixed disk 3. A gear disk 43 is concentrically fixedly sleeved at the right end of the fixed sleeve 4. A planetary gear 45 is concentrically fixedly sleeved at an inner end of each planetary shaft 44. Each planetary gear 45 is meshed and connected with the gear disk 43. The planetary gears 45 on the planetary shafts 44 can perform meshing self-rotation along the gear disk 43, driving the planetary shafts 44 and the first reamer 46 to perform planetary rotation.

[0064] In the middle of the concentric disk 33, a fixedly arranged fixing shaft 35 with a penetrating distribution is provided. An outer end portion of the fixing shaft 35 is sleeved with a concentrically fixedly connected conical column 36. A conical spiral blade 37 is fixedly arranged on an outer surface of the conical column 36. The conical column 36 and the conical spiral blade 37 can break the blocked part of the blocked pipeline. An inner end portion of the fixing shaft 35 sequentially rotates through the fixing sleeve 4, the circular fixing disk 3, and the second hexagonal disk 12. A second square through hole is formed in the middle of the hexagonal fixing disk 18. A second motor 34 is installed inside the second square through hole. An end portion of a motor shaft of the second motor 34 is fixedly connected to the inner end portion of the fixing shaft 35. The motor shaft of the second motor 34 can drive the fixing shaft 35, the concentric disk 33, the conical column 36, and the conical spiral blade 37 to rotate;

[0065] The conical column 36 and the conical spiral blade 37 can play a role in initially breaking and loosening the silt during the pipeline dredging process. Due to their conical shape, when advancing forward, they can insert into the silt layer like a wedge and decompose the relatively compact silt blocks;

[0066] A number of first cutters 46 that rotate like planets can finely clean the stubborn silt near the inner wall of the pipeline. These first cutters 46 rotate around the conical column 36, just like planets orbiting the sun. Their rotation direction and speed can be designed according to the actual situation; the first cutters 46 can penetrate into the gaps and corners of the inner wall of the pipeline and scrape off the silt adhering to the pipe wall.

[0067] Embodiment 4: On the basis of Embodiment 3, this embodiment further includes the following content:

[0068] As Figure 7 and Figure 8 shown, a concentrically distributed gear ring 5 is fixedly arranged on a right side surface of the circular fixing disk 3. An inner section of each planetary slide rod 52 is sleeved with a concentrically fixedly connected widened gear 56. Each widened gear 56 is meshed with the gear ring 5, and the teeth of the widened gear 56 are slidably connected to the teeth of the gear ring 5 along the axial line direction of the widened gear 56. The widened gears 56 on the planetary slide rod 52 can meshingly rotate around the gear ring 5 and drive the planetary slide rod 52 and the second cutter 57 to rotate like planets;

[0069] A pair of concentrically fixedly connected limiting disks 41 are sleeved in the middle of the fixing sleeve 4, and annular wave grooves 42 are formed on opposite surfaces of the pair of limiting disks 41. An I-shaped shaft 53 is fixedly arranged at an inner end portion of each planetary slide rod 52. A rectangular sleeve 54 is rotatably sleeved in the middle of each I-shaped shaft 53. The I-shaped shafts 53 on the planetary slide rod 52 can drive the rectangular sleeve 54 to revolve along the pair of limiting disks 41;

[0070] The rectangular sleeve 54 is located between a pair of limiting discs 41 and is slidably connected to the opposite faces of the pair of limiting discs 41. A pair of limiting pin shafts 55 are fixedly provided on both side faces of the rectangular sleeve 54. The outer ends of the pair of limiting pin shafts 55 are respectively slidably engaged in the annular wave grooves 42 on the same side. Under the limiting action formed by the limiting pin shafts 55 and the annular wave grooves 42, the rectangular sleeve 54 and the I-shaped shaft 53 can be driven to slide along the annular wave grooves 42;

[0071] When the second reamer 57 makes a planetary rotation, it can perform a circular motion around the hollow rotating cylinder 31, enabling the second reamer 57 to clean an annular area on the inner wall of the pipeline with the hollow rotating cylinder 31 as the center; through the planetary rotation, the second reamer 57 can reach every corner of this annular area, effectively removing stubborn stains adhering to the pipe wall and avoiding the occurrence of dead corners in dredging;

[0072] The second reamer 57 can reciprocally slide, which enables its cleaning range not to be limited to just one annular area. During the sliding process, the second reamer 57 can move along the axial direction of the pipeline, thereby being able to cover different positions on the inner wall of the pipeline. Combining with the planetary rotation, the cleaning trajectory of the second reamer 57 changes from a simple annular shape to a spiral shape, greatly increasing the coverage range of dredging.

[0073] Specifically, the working principle and operation method of the present invention are as follows:

[0074] Step 1, when dredging a clogged pipeline, place the hexagonal cylinder 1 and the hollow rotating cylinder 31 into one end port of the clogged pipeline, with the conical column 36 and the conical spiral blade 37 facing the clogged part of the clogged pipeline;

[0075] 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. Under the spiral action of the lead screw 21 and the threaded cylinder 22, drive the hexagonal sliding disc 13 to slide towards the hexagonal center disc 16 along the I-shaped slide rail 15;

[0076] Step 3, under the hinge action of the hinge connecting rod 28, drive the first swing arm 23 to swing outwards along the first ear seat 17, and drive the second swing arm 25 to swing outwards along the second ear seat 19 through the parallel connecting rod 27, synchronously driving the first roller 24 and the second roller 26 to abut against the inner wall of the clogged pipeline;

[0077] 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 disc 33, the conical column 36, and the conical spiral blade 37 to rotate, synchronously driving the hollow rotating cylinder 31 and the annular rail 32 to rotate along the annular slot;

[0078] Step Five: The planetary shafts 44 and the first reamer 46 on the concentric disk 33 revolve with the concentric disk 33. The planetary gears 45 on the planetary shafts 44 mesh and rotate around the gear disk 43, driving the planetary shafts 44 and the first reamer 46 to perform planetary rotation.

[0079] Step Six: The planetary slide bars 52 and the second reamer 57 on the hollow rotating cylinder 31 revolve with the hollow rotating cylinder 31. The widened gears 56 on the planetary slide bars 52 mesh and rotate around the gear ring 5, driving the planetary slide bars 52 and the second reamer 57 to perform planetary rotation.

[0080] The I-shaped shafts 53 on the planetary slide bars 52 drive the rectangular sleeves 54 to revolve around a pair of limit disks 41. Under the limiting effect formed by the limit pin shafts 55 and the annular wave grooves 42, the rectangular sleeves 54 and the I-shaped shafts 53 are driven to slide along the annular wave grooves 42, synchronously driving the planetary slide bars 52 and the second reamer 57 to reciprocate along the fixed ring 51.

[0081] Step Seven: Push the hexagonal cylinder 1 and the hollow rotating cylinder 31 into the blocked pipeline, driving the first rollers 24 and the second rollers 26 to roll inward along the inner wall of the blocked pipeline, and crushing the blocked part of the blocked pipeline through the conical columns 36 and the conical spiral blades 37. Under the combined action of the first reamer 46 and the second reamer 57, the blocked part of the blocked pipeline is completely broken, thereby dredging the blocked pipeline and finally completing the dredging operation of the blocked pipeline.

[0082] When the present invention is used for pipeline dredging, the hexagonal cylinder 1 and the rollers can adapt to different pipe diameters, move stably and reduce damage; the combination of the conical columns 36, the conical spiral blades 37, the first reamer 46, etc. can dredge efficiently, and can achieve comprehensive dead-angle-free dredging; the planetary rotation and reciprocating sliding of the second reamer 57 are combined to expand the dredging range, enhance the adaptability and flexibility, and improve the dredging depth and quality; the whole device is simple to operate, improves the dredging efficiency and has a low labor cost.

[0083] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
