Description

Technical Field

[0001] This invention belongs to the field of municipal equipment technology, and in particular relates to a municipal drainage pipeline dredging mechanism. Background Technology

[0002] Municipal drainage pipelines are crucial urban infrastructure, primarily responsible for rainwater collection, sewage transport, and flood control and drainage. They are vital for maintaining normal urban operations and ensuring urban environmental sanitation. Because these pipelines are laid underground for extended periods, their inner walls easily accumulate impurities such as silt, mud, stones, household waste, and solidified dirt. This can easily lead to problems like pipe diameter reduction, blockages, and poor drainage. During the rainy season, this can cause urban flooding, road waterlogging, and sewage backflow, severely impacting urban traffic and residents' lives. Therefore, regular dredging of these pipelines is a key aspect of municipal operation and maintenance.

[0003] Currently, municipal drainage pipeline dredging operations mostly utilize high-pressure water flushing equipment. This type of equipment relies on high-pressure water flow to impact and flush away loose silt and lightweight debris from the inner wall of the pipeline. It has the advantage of being easy to operate and is the mainstream dredging equipment in the industry at present. However, in actual complex working conditions, this type of traditional equipment has certain defects and operational limitations: Firstly, existing traditional water pressure flushing equipment relies solely on high-pressure water flow to complete dredging operations. The internal components of municipal pipelines are complex, including not only loose floating mud but also solidified silt, adhered dirt, large pieces of sand and gravel, and other hard and stubborn impurities. Due to the lack of a mechanism with a crushing effect, simple water pressure impact cannot break down and decompose the impurities; it can only remove loose surface debris. To meet the cleaning standards, the equipment needs to continuously output high-pressure water flow for repeated flushing, which not only wastes a lot of water resources but also increases the equipment's resistance to movement due to unbroken hard impurities, resulting in slow feed speed, long operation cycles, and low overall dredging efficiency.

[0004] Secondly, the existing dredging equipment has poor pipe compatibility. Considering the diverse diameters of municipal drainage pipes, and the fact that traditional dredging equipment is mostly a fixed structure, the working dimensions need to be manually adjusted and calibrated in advance according to the pipe specifications. After adjustment, the structural dimensions are fixed. During pipe operation, when encountering obstacles such as protrusions, misalignments, or large accumulations of impurities on the inner wall of the pipe, it is unable to adaptively adjust its working posture and travel size according to the internal working conditions of the pipe, which can easily lead to problems such as jamming and stagnation, affecting the progress of the operation. It cannot adapt to general operations in different cleaning environments inside the pipe, which seriously affects the continuity of dredging operations and the overall work process, and increases the investment cost of pipe dredging operations.

[0005] In summary, existing municipal drainage pipeline dredging equipment suffers from technical defects such as lack of debris crushing function, high water consumption, low operating efficiency, and poor pipe diameter self-adjustment capability, making it difficult to adapt to the high-efficiency dredging needs of multi-specification pipelines and complex working conditions. Therefore, based on the above-mentioned shortcomings of the existing technology, this invention proposes a municipal drainage pipeline dredging mechanism. Summary of the Invention

[0006] This invention addresses the technical problems existing in the aforementioned pipeline dredging process by proposing a municipal drainage pipeline dredging mechanism that is rationally designed, simple in structure, easy to process, and can be equipped with a crushing mechanism.

Furthermore, it features a dynamic adaptive adjustment structure, which on the one hand can adapt to various specifications of municipal drainage pipelines, improving equipment versatility and reducing operation, debugging, and equipment investment costs; on the other hand, it can adjust the working posture in real time according to the complex working conditions inside the pipeline, avoiding equipment jamming, ensuring continuous operation, buffering operational impacts, and improving the operational stability of the device.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-11As shown, a municipal drainage pipeline dredging mechanism is provided. To achieve the above-mentioned objectives, the technical solution adopted by this invention is a municipal drainage pipeline dredging mechanism, including a dredging mechanism body 1. The dredging mechanism body 1 mainly consists of a traveling mechanism 2, a longitudinal rotation mechanism 4, a cover 5, a mounting plate 6, a swing mechanism, a transmission mechanism 8, a crushing component 9, a water spraying mechanism 10, and an auger material distribution mechanism 13. Among them, the traveling mechanism 2 serves as the load-bearing base and driving core of the whole machine, undertaking four core functions: overall equipment support, pipe diameter adaptive adaptation, dynamic shock absorption and buffering, and uniform speed driving. In particular, it is used to drive the entire dredging mechanism body 1 to move autonomously in the pipeline and adapt to different pipe diameters. The longitudinal rotation mechanism 4 is the core mechanism for overall angle adjustment of the equipment, and is fixedly mounted. On the single-sided support 41 of the traveling mechanism 2, it is mainly used to achieve 360° circumferential precise rotation and positioning of the entire structure, including the cover 5, internal swing mechanism, crushing component 9, water spraying mechanism 10, and water conveying mechanism. This solves the problems of fixed operating angle, silt accumulation at the top of the pipe, dead corners on the side walls, and inability to clean bottom clumps in traditional dredging equipment. The core of the swing mechanism is the multi-link linkage structure of the spatial linkage mechanism 7, which is the core power transmission unit for the equipment to achieve reciprocating dynamic crushing. Through the spatial linkage mechanism 7, the crushing component 9 achieves multi-degree-of-freedom swinging. It is fully enclosed and integrated inside the cover 5, adapting to narrow and enclosed working spaces. It is mainly used to convert rotational power into large-angle, highly stable reciprocating swinging power, providing a continuous and uniform dynamic driving force for subsequent crushing operations. The transmission mechanism 8 will... The power of the swing mechanism is transmitted to the crushing component 9. The transmission mechanism 8 is the core component for power conversion, accurately connecting the front swing mechanism and the rear crushing component 9. Its main function is to convert the high-speed, small-amplitude swing power output by the linkage mechanism into low-speed, high-torque, and highly stable large-amplitude reciprocating swing power. The crushing component 9 is the direct crushing unit for solid blockage impurities in the pipeline. It adopts a composite dual crushing mode of overall reciprocating swing + local high-speed rotation. It can achieve layered, graded, and thorough crushing of impurities of different hardness, such as soft floating mud, semi-solidified silt, completely solidified lumps, and gravel debris in the pipeline. The water spraying mechanism 10 is the core sealing and water conveyance component under dynamic rotation conditions, which solves the contradiction between the 360° rotation and swing of the operating mechanism and the continuous water conveyance of the fixed pipeline. The shield achieves a stable water delivery function that combines static and dynamic operation, with no leakage, no water interruption, and no pressure loss. It also uses high-pressure water flow to flush away residual sludge on the inner wall of the pipe. The water delivery component 11 receives the constant pressure water flow introduced by the spray mechanism 10. Based on the Venturi fluid dynamics principle, it realizes secondary pressurization of water flow, uniform flow distribution, and all-round multi-angle spraying, which greatly improves the flushing force and sludge removal coverage. The screw conveyor material equalization mechanism 13 is the auxiliary core mechanism for anti-clogging, material guiding, and sludge equalization of the equipment. It operates synchronously with the second rotating rod 73 without the need for additional power drive. It can be adapted to the entire process of crushing, spraying, and moving. It mainly realizes four functions: crushed debris guidance, sludge equalization, sedimentation and anti-clogging, and nozzle self-cleaning. It is used to evenly disperse impurities after crushing and prevent them from accumulating and hindering the movement of the equipment.

[0023] To ensure smooth operation of the equipment, the traveling mechanism 2 consists of at least three parallel ring frames 21. A support plate 22 is installed inside each ring frame 21, providing rigid support for the entire equipment and ensuring the parallelism of the multiple ring frames 21 to prevent deformation under pressure. A traveling component 3 with adaptive adjustment function is installed on the outer side between two adjacent ring frames 21. A strut 23 is installed between two adjacent ring frames 21 to lock the distance between adjacent ring frames 21, ensuring the overall stability of the traveling mechanism 2. Furthermore, the traveling mechanism 2 includes a rotating rod 31 hinged to the outer side of the ring frame 21. A roller 32 is installed at the end of the rotating rod 31. A slider 33 is installed on the outer side of the strut 23, and a compression spring 34 is installed on one side of the slider 33. A spring damping assembly 35 with telescopic damping performance is provided between the moving rod 31 and the slider 33. The spring damping assembly 35 is an elastic damping component with a telescopic damping coefficient. The two ends of the spring damping assembly 35 are respectively hinged to the rotating rod 31 and the slider 33 to realize adaptive adjustment of the travel size and shock absorption during operation. The adaptive adjustment of the pipe diameter during use is as follows: when the dredging mechanism body 1 is placed into the pipe to be cleaned, the compression spring 34 is in a pre-compressed state. Its elastic force is transmitted to the spring damping assembly 35 through the slider 33, which in turn pushes the rotating rod 31 to open outward around its hinge point with the ring frame 21, so that the roller 32 is tightly attached to the inner wall of the pipe. When the inner diameter of the pipe changes, the compression spring 34 will automatically extend or compress, driving the slider. 33 slides axially along the support rod 23. The opening angle of the rotating rod 31 is adjusted by the spring damping assembly 35, so that the roller 32 always maintains effective contact with the inner wall of the pipe. This structure can be adapted to drainage pipes with inner diameters that vary arbitrarily within the design range, without manual adjustment, greatly improving the versatility of the equipment. In addition, for the travel process of the traveling assembly 3: each set of rotating rods 31 can be independently equipped with a travel drive system on its outer side. That is, a travel drive motor is installed on the outer side of the rotating rod 31. The output end of the motor is connected to one end of the roller 32 through a pair of bevel gears arranged at right angles. When the travel drive motor is running, the power is transmitted to the roller 32 through the bevel gears, driving the roller 32 to roll along the inner wall of the pipe, thereby driving the entire dredging machine. The main body 1 moves forward or backward within the pipeline. A bevel gear drive allows for 90° rotation of the power, enabling the motor to be installed parallel to the pipeline axis, effectively saving radial space and avoiding interference with the pipeline wall. The driving bevel gear is fixed to the end of the motor's output shaft, while the driven bevel gear is fixed to the end of the central rotating shaft of the roller 32. The precise meshing of the two gears smoothly converts the vertical rotational power of the motor into the horizontal rolling power of the roller 32. By uniformly controlling the forward and reverse rotation and speed synchronization of multiple drive motors through the electrical control system, the equipment can be precisely controlled to move forward, backward, start, stop, and adjust its speed within the pipeline. The independent drive structure of each motor ensures uniform power output to each roller 32, preventing equipment deviation or misalignment due to insufficient power on one side. Furthermore…The established traveling component 3 also features excellent shock absorption and obstacle-crossing capabilities: when the equipment encounters protrusions, depressions, or small obstacles on the inner wall of the pipe during operation, the roller 32 will experience radial impact force. This impact force is transmitted to the spring damping component 35 through the rotating rod 31. The damping spring inside the spring damping component 35 undergoes elastic deformation, absorbing most of the impact energy. Simultaneously, in conjunction with the elastic action of the compression spring 34, the rotating rod 31 can quickly and adaptively adjust its position, ensuring that the roller 32 always remains in contact with the inner wall of the pipe, preventing the equipment from bumping or jamming. This shock-absorbing structure not only improves the smoothness of the equipment's movement but also effectively protects internal precision components from vibration damage, extending the equipment's service life.

[0024] To improve the functionality of the device, a support frame 41 is provided on the outer side of one side of the ring frame 21. The longitudinal rotation mechanism 4 includes a limiting plate 42 set on one side of the support frame 41. A rotating plate 43 with a T-shaped cross-section is set inside the limiting plate 42 and is rotatably connected to the limiting plate 42. A ring rack 44 is set inside the rotating plate 43 near one side. That is, one end of the inner side of the rotating plate 43 is rotatably connected to the limiting plate 42. The outer periphery of the rotating plate 43 is concave and provides a convenient installation position for the ring rack 44. A rotating rod 45 is set on the limiting plate 42. Three rotating rods 45 are arranged in a 120° equidistant ring array around the hollow tube 48 on the limiting plate 42. On the face, the end of the rotating rod 45 is provided with a drive gear 46, which meshes with the ring rack 44. A hollow rotary motor 47 is provided on the support plate 22. A hollow tube 48 is provided at the output end of the hollow rotary motor 47. Two first rotating wheels 49 are arranged side by side on the outer side of the hollow tube 48. A second rotating wheel 410 is provided on each rotating rod 45. A synchronous belt 411 is provided between the first rotating wheel 49 and the second rotating wheel 410. The process of circumferential rotation drive is as follows: when it is necessary to adjust the circumferential working position of the crushing component 9 and the water spraying mechanism 10, the hollow rotary motor 47 is started. The output end of the hollow rotary motor 47 drives the hollow tube 48 to rotate synchronously. The two first rotating wheels 49 on the outer side of the hollow tube 48 rotate synchronously. The rotating wheel 49 rotates accordingly, and drives the second rotating wheels 410 on the three rotating rods 45 to rotate via the synchronous belt 411. When the rotating rod 45 rotates, the drive gear 46 at its end rotates synchronously. Through meshing with the ring rack 44, it drives the rotating disk 43 to rotate 360° around its axis within the limiting disk 42. Since the cover 5 and the mounting disk 6 are both fixedly mounted on the rotating disk 43, the rotation of the rotating disk 43 will drive the entire working end, including the swing mechanism, transmission mechanism 8, crushing assembly 9, water spray mechanism 10, and auger material distribution mechanism 13, to rotate synchronously. In the above process, three drive gears 46 arranged in a ring-shaped equidistant array simultaneously mesh with the ring rack 44 to transmit power. The rotation allows for more even force distribution on the rotating disk 43, preventing gear wear or damage caused by excessive force at a single point. This significantly improves the load-bearing capacity and operational stability of the transmission system. The T-shaped cross-section design of the rotating disk 43, in conjunction with the limiting disk 42, effectively restricts the axial displacement of the rotating disk 43, preventing it from shifting during rotation and ensuring the rotational accuracy of the working end. This also improves transmission stability and load-bearing capacity. Furthermore, the hollow design of the hollow rotating motor 47 and the hollow tube 48 provides a passage for the installation of water pipes and some electrical components, allowing water pipes and cables to pass through the inside of the equipment, avoiding the problem of external pipeline entanglement. It also makes the overall structure of the equipment more compact and aesthetically pleasing.

[0025] To further improve the functionality of the equipment, a swing mechanism is installed inside the enclosure 5. The swing mechanism includes a spatial linkage mechanism 7 and a transmission mechanism 8. The spatial linkage mechanism 7 includes a first rotating rod 71 mounted on the mounting plate 6. It should be further noted that a hollow rotating platform is fixedly installed on one side of the mounting plate 6. The output end of the hollow rotating platform is fixedly connected to the first rotating rod 71, providing driving power to the swing mechanism. When the hollow rotating platform operates, it drives the first rotating rod 71 to rotate around its axis, providing power input to the swing mechanism to ensure the smooth operation of the crushing component 9, the water spraying mechanism 10, and the auger material distribution mechanism 13. A first rotating plate 72 with a key-shaped design is provided on one side of a rotating rod 71, and a second rotating rod 73 is provided on one side of the cover 5. A second rotating plate 74 is provided on the outer side of the second rotating rod 73. Movable rods 75 are provided on the first rotating plate 72 and the second rotating plate 74, respectively, and can move relative to each other. Both the first rotating plate 72 and the second rotating plate 74 have circular sliding grooves. The ends of the two movable rods 75 are respectively embedded in the corresponding sliding grooves, allowing them to reciprocate adaptively along the sliding grooves, adapting to the circumferential rotation trajectory of the rotating plates and compensating for displacement differences during rotation. A connecting block 76 is provided between the two movable rods 75 to connect... A sliding rod 77 is provided inside block 76 and is slidably connected to connecting block 76. Connecting plates 78 are provided at both ends of the sliding rod 77, and a rotating shaft 79 is provided above the other side of the connecting plate 78. The transmission working principle of the spatial linkage mechanism 7 is as follows: When the first rotating rod 71 rotates, it drives the key-shaped first rotating plate 72 to rotate synchronously. The moving rod 75 on the first rotating plate 72 performs planar motion under the drive of the first rotating plate 72, and simultaneously drives the moving rod 75 on the second rotating plate 74 to move through the connecting block 76. During this process, the connecting block 76 slides along the axial direction of the sliding rod 77 to compensate for the displacement difference between the two moving rods 75. As the first rotating plate 72... As it continues to rotate, the slide bar 77 will perform a compound motion in space, generating both horizontal rotation and a certain degree of oscillation. Ultimately, the power is transmitted to the rotating shaft 79 on the connecting plates 78 at both ends of the slide bar 77. This spatial linkage mechanism 7 can transform the single rotational motion of the first rotating rod 71 into a multi-degree-of-freedom oscillating motion of the rotating shaft 79, allowing the rotating shaft 79 to adjust its posture within a larger spatial range. Compared to traditional single-degree-of-freedom oscillating mechanisms, the motion trajectory of this spatial linkage mechanism 7 is more flexible and can cover a larger working area inside the pipeline. This allows the crushing component 9 to effectively crush solidified impurities at different locations on the inner wall of the pipeline, ensuring the dredging effect.

[0026] To ensure the effective transmission of driving power, the transmission mechanism 8 includes a worm gear 81 mounted on a rotating shaft 79. A mounting base 82 is provided on the inner side of the cover 5, and a worm wheel 83 is provided inside the mounting base 82. A swing rod 84 that rotates synchronously with the worm wheel 83 is provided on the outer side of the worm wheel 83. The specific operation process and effect are as follows: when the rotating shaft 79 reciprocates under the drive of the spatial linkage mechanism 7, the worm gear 81 fixedly mounted on the rotating shaft 79 rotates synchronously. The worm gear 81 meshes with the worm wheel 83 to transmit power, converting the reciprocating motion of the rotating shaft 79 into the rotational motion of the worm wheel 83. The worm gear 83 and worm 81 transmission has a large transmission ratio, which can reduce speed and increase torque while transmitting power, so that the swing rod 84 can obtain a large output torque, thereby driving the crushing component 9 to generate sufficient crushing force, which can effectively crush hard solidified sludge and other materials in the pipeline. Of course, the worm gear 83 and worm 81 transmission has a reverse self-locking characteristic, that is, only the worm 81 can drive the worm gear 83 to rotate, but the worm gear 83 cannot drive the worm 81 to rotate. This characteristic allows the crushing component 9 to maintain a stable posture during operation and will not rotate in the opposite direction due to the reaction force of impurities, ensuring the safety and reliability of the crushing operation. The worm gear 83 and worm 81 transmission has a compact structure, which can realize the transmission of power within the limited space of the enclosure 5, saving installation space and making the overall structure of the equipment more compact.

[0027] To break up solidified impurities inside the pipeline, the crushing assembly 9 includes a mounting plate 91 positioned between two swing rods 84. A rotating rod 92 is mounted on the mounting plate 91, and a crushing cone 93 is mounted on the outer side of the rotating rod 92. The crushing process is as follows: when the worm gear 83 rotates, it drives the swing rods 84, which are fixedly connected to it, to rotate synchronously. The simultaneous rotation of the two swing rods 84 causes the mounting plate 91 to swing in an arc within space, which in turn causes the rotating rod 92 and the crushing cone 93 to swing synchronously. During the swinging process, the crushing cone 93 uses its sharp tip and sides to continuously impact and squeeze the solidified impurities inside the pipeline, breaking large pieces of solidified silt, stones, tree roots, etc., into smaller particles, facilitating subsequent water flushing and transportation. Of course, it can also be used for further processing. To further improve crushing efficiency, a crushing drive motor is fixedly installed on the inner side of the mounting plate 91. The output end of the crushing drive motor is fixedly connected to the rotating rod 92. When the crushing drive motor runs, it drives the rotating rod 92 and the crushing cone 93 to rotate at high speed. The rotation of the crushing cone 93, combined with its oscillating motion, can generate a more complex crushing trajectory, impacting and cutting impurities from all directions, greatly improving the crushing effect and crushing speed. In the above process, the conical design of the crushing cone 93, with its sharp end, can easily penetrate into the solidified impurities, generating greater local stress, making the impurities easier to crush. The side of the crushing cone 93 is also provided with a spiral cutting edge, which can cut the impurities during the rotation process, further improving the crushing efficiency.

[0028] To ensure smooth high-pressure water delivery and to clean silt and other impurities from the pipes in conjunction with the crushing component 9, the water spraying mechanism 10 includes an I-shaped sleeve 101 fitted onto a second rotating rod 73 extending outside the cover 5. An inlet pipe 102 is located on the outer side of the sleeve 101. An annular groove 103 is formed on the inner side of the sleeve 101 near the inlet pipe 102. An arc-shaped groove 104 is formed on the outer side of the second rotating rod 73 corresponding to the annular groove 103. A connecting pipe 105 is installed inside the second rotating rod 73 corresponding to the inlet pipe 102, and it communicates with the annular groove 103 and the arc-shaped groove 104. A sealing ring 106 is also provided between the second rotating rod 73 and the sleeve 101. A water delivery component 11 is located on the outer side of the water spraying mechanism 10. The system includes a liquid collecting pipe 111 housed within the second rotating rod 73. Conical grooves 112 are formed on both sides of the liquid collecting pipe 111. A branch pipe 113 is located on the outer side of the liquid collecting pipe 111, and a water conveying plate 114 is located at the end of the branch pipe 113. A first nozzle 115 is located on the outer periphery of the water conveying plate 114, and a second nozzle 116 is located on the outer side of the water conveying plate 114. A third nozzle 117, designed with an inclined shape, is located on one side of the second nozzle 116. One end of the water inlet pipe 102 passes through the mounting plate 6. A water supply connection assembly 12 is also included. The water supply connection assembly 12 includes a water collection pipe 121, a rotary joint 122, a water delivery pipe 123, a pump body 124, and a water storage tank 125. Specifically, the end of the water inlet pipe 102 is provided with a water collection pipe 121. A rotary joint 122 is provided on the outside of 121 and is located inside the hollow tube 48. A water supply pipe 123 is provided on one side of the rotary joint 122 and connected to a pump body 124. A water storage tank 125 is provided on one side of the pump body 124. The water storage tank 125 is a clean water storage base to provide a continuous water source for dredging operations. The high-pressure pump body 124 is the power source for water delivery and is responsible for drawing water and establishing water pressure. The specific operation process is as follows: The rotating water delivery process is as follows: The sleeve 101 is fixedly installed on the cover 5 and does not rotate with the second rotating rod 73. When the second rotating rod 73 rotates under the drive of the spatial linkage mechanism 7, the annular groove 103 on the inner side of the sleeve 101 and the arc-shaped groove 104 on the outer side of the second rotating rod 73 always remain in communication. The high-pressure water delivered from the outside passes through... The inlet pipe 102 enters the annular groove 103 of the sleeve 101, and then enters the liquid collection pipe 111 inside the second rotating rod 73 through the arc-shaped groove 104 and the connecting pipe 105. The sealing ring 106 set between the second rotating rod 73 and the sleeve 101 can effectively prevent high-pressure water leakage and ensure stable water supply pressure. This rotating water supply structure cleverly solves the water supply problem between the rotating part and the fixed part, allowing the water spraying mechanism 10 to rotate with the working end, while ensuring continuous delivery of high-pressure water. After the high-pressure water enters the liquid collection pipe 111, it flows through the conical grooves 112 on the left and right sides of the liquid collection pipe 111. According to the Venturi principle, the water flow velocity will increase sharply in the contraction section of the conical groove 112, and the pressure energy will be converted into kinetic energy, so that the water flow can obtain a higher jet speed.The accelerated high-pressure water is evenly distributed to each water delivery plate 114 through multiple branch pipes 113 outside the collection pipe 111, and finally sprayed out through the nozzles on the water delivery plate 114. This achieves water flow acceleration and distribution to a certain extent. In addition, the water delivery plate 114 is equipped with three nozzles in different directions: the first nozzle 115 is arranged radially along the outer circumference of the water delivery plate 114 to flush residual sludge on the inner wall of the pipe; the second nozzle 116 is arranged axially along the water delivery plate 114 to flush impurities directly in front of the pipe; and the third nozzle 117 is arranged at an angle to flush the angled area between the inner wall and the bottom of the pipe. The three nozzles work together to flush the inner wall of the pipe in all directions without dead angles, ensuring... The dredging is thorough. Furthermore, since the water spray mechanism 10 rotates circumferentially along with the rotating disk 43, the end of the inlet pipe 102 passes through the mounting disk 6 and connects to the rotary joint 122 via the water collection pipe 121. One end of the rotary joint 122 is fixedly connected to the water collection pipe 121, and the other end is rotatably connected to the water delivery pipe 123. The water delivery pipe 123 is housed within the hollow pipe 48 to ensure the water delivery process and adapts to the circumferential rotation of the water spray mechanism 10, ensuring that the water delivery pipe 123 does not become entangled. Simultaneously, the hollow pipe 48 also rotates with the hollow rotary motor 47, and the rotary joint 122 is also rotatably connected to the hollow pipe 48, further ensuring the smooth input of high-pressure water.

[0029] To further improve the practicality of the equipment, the auger material distribution mechanism 13 includes a sleeve 131 sleeved on the outside of the second rotating rod 73. An auger blade 132 is provided on the outside of the sleeve 131. The auger blade 132 can adopt a spiral gradient blade structure. The outer diameter of the blade is adapted to the pipeline working space. It can achieve large-scale water disturbance and slag pushing without scraping the inner wall of the pipeline. The specific operation process and effect are as follows: its material distribution driving effect is: the auger material distribution mechanism 13 is fixedly sleeved on the outside of the second rotating rod 73 through the sleeve 131. Therefore, when the second rotating rod 73 rotates under the drive of the spatial linkage mechanism 7, the sleeve 131 and the auger blade 132 will rotate synchronously with the second rotating rod 73. It also has the function of impurity dispersion and conveying: the impurities after being crushed by the crushing component 9 will be scattered at the bottom of the pipe. When the auger blade 132 rotates, it will generate a spiral propulsion force on these impurities, which will be evenly dispersed and conveyed forward. This structure can effectively prevent the impurities after crushing from accumulating in front of the equipment, avoiding the impurities from hindering the equipment's progress. At the same time, it can also make the impurities fully mixed with the high-pressure water flow, so that the water flow can carry them away, improving the dredging efficiency. In addition, it also has an anti-entanglement effect: the auger blade 132 adopts a continuous spiral design, which can cut off and convey flexible impurities such as weeds and strips of cloth that are entangled on the equipment during the rotation process, effectively preventing flexible impurities from entangled on the equipment parts and ensuring the normal operation of the equipment.

[0030] The complete workflow of this embodiment is as follows: The dredging mechanism body 1 is placed at the inlet of the drainage pipe to be cleaned. The compression spring 34 automatically pushes the slider 33 to slide along the support rod 23. The spring damping component 35 drives the rotating rod 31 to open outward, so that the roller 32 fits tightly against the inner wall of the pipe, completing the adaptive adjustment of the pipe diameter. The travel drive motor is started, and the roller 32 is driven to rotate through the bevel gear transmission, driving the equipment to enter the inside of the pipe.

[0031] During the movement of the equipment inside the pipeline, the spring damping component 35 and the compression spring 34 work together to automatically adapt to the unevenness of the inner wall of the pipeline and small obstacles, ensuring smooth movement. When a large amount of solidified impurities are detected at a certain position in the pipeline, the movement stops and the hollow rotary motor 47 is started. The hollow rotary motor 47 drives the rotating disk 43 to rotate circumferentially through the synchronous belt 411, the drive gear 46 and the ring rack 44, adjusting the crushing component 9 and the water spraying mechanism 10 to the position facing the impurities.

[0032] The hollow rotating platform is started, which drives the first rotating rod 71 to rotate. The first rotating rod 71 transmits power to the rotating shaft 79 through the spatial linkage mechanism 7, causing the rotating shaft 79 to perform multi-degree-of-freedom swing motion. The rotating shaft 79 drives the swing rod 84 to rotate through the worm gear 81 and worm wheel 83, which in turn drives the mounting plate 91, the rotating rod 92 and the crushing cone 93 to swing in an arc. At the same time, the crushing drive motor is started, which drives the rotating rod 92 and the crushing cone 93 to rotate at high speed. Under the combined motion of swinging and rotation, the crushing cone 93 impacts, squeezes and cuts the solidified impurities in the pipeline, crushing them into fine particles.

[0033] While the crushing operation is underway, the pump body 124 is started to pressurize the water in the water storage tank 125 and deliver it to the annular groove 103 of the casing 101 through the water delivery pipe 123, rotary joint 122, water collection pipe 121 and water inlet pipe 102. The high-pressure water enters the liquid collection pipe 111 through the arc groove 104 and connecting pipe 105, and after being accelerated by the conical groove 112, it is distributed to each water delivery plate 114 through the branch pipe 113. Finally, it is sprayed out through the first nozzle 115, the second nozzle 116 and the third nozzle 117 to flush the inner wall of the pipe in all directions. At the same time, the second rotating rod 73 drives the auger blade 132 to rotate synchronously, which evenly disperses and conveys the crushed impurities forward, preventing them from accumulating and obstructing the movement of the equipment, and making the impurities fully mixed with the water flow so that the water flow can carry them away.

[0034] After completing the dredging operation at the current location, continue driving the equipment forward and repeat the above-mentioned circumferential position adjustment, crushing, water spraying and material equalization operations until the dredging work of the entire pipeline section is completed. After the dredging is completed, control the equipment to move in the opposite direction and exit the pipeline to complete this dredging task.

[0035] In the above process: This embodiment achieves a comprehensive improvement in dredging capacity, adaptability, and reliability through multi-mechanism collaborative innovation, and significantly improves dredging efficiency and thoroughness: It adopts a dual-power composite crusher of swing and rotation, which can efficiently crush solidified silt, stones, and other hard impurities. Combined with 360° circumferential rotation and multi-degree-of-freedom swing, it can achieve full-section operation without dead angles in the pipeline. The Venturi water flow accelerates and enhances the flushing force. The integrated screw conveyor evens material, prevents accumulation and entanglement, and ensures continuous and uninterrupted operation. It has strong adaptability to working conditions and wide versatility. The traveling mechanism 2 adopts a dual-elastic adaptive structure, which can automatically adapt to any pipe diameter within the design range without manual adjustment. It has significant shock absorption and obstacle crossing ability and can smoothly pass through complex pipelines with deformation and scaling. It is stable and reliable in operation with a low failure rate. The longitudinal rotation mechanism 4 adopts a three-point meshing transmission, which has uniform force and strong load-bearing capacity.
