Description

Technical Field

[0001] This utility model relates to the technical field of pipe cleaning devices, and in particular to a drainage pipe network dredging and cleaning equipment. Background Technology

[0002] As the age of urban pipe networks continues to increase, a large number of drainage pipes in old urban areas, combined sewer systems, and industrial plant pipelines have been in use for a long time. Under the combined effects of water deposition, media compaction, and salt solidification, hard, compacted silt layers are easily formed inside the pipes. This type of hard silt has strong adhesion and is difficult to clean, gradually becoming a key problem to be addressed in pipe network operation and maintenance.

[0003] In existing technologies, pipeline cleaning mostly employs high-pressure water jet flushing equipment or rotary cutterhead sludge removal equipment. High-pressure water jet methods not only consume large amounts of water, but the high-pressure water flow can also cause impact damage to brittle pipes such as clay pipes and old concrete pipes. Rotary cutterhead equipment relies on rotary cutting operations, which can easily generate radial oscillations during operation, making it prone to impacting the inner wall of the pipe. It is also susceptible to problems such as debris entanglement and rapid blade wear, making it difficult to handle the specialized cleaning of hard sludge inside old pipes of different materials. In short, there is a problem of low efficiency in cleaning hard sludge from pipelines. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a drainage pipe network dredging and cleaning device, which improves the cleaning efficiency of hard sludge in the pipes.

[0005] The objective of this utility model is achieved through the following technical solution:

[0010] A reciprocating drive mechanism is installed in the installation space; the reciprocating drive mechanism drives the connecting end connected to the sliding rod, and the reciprocating drive mechanism is used to drive the sliding rod to reciprocate along its own axis, thereby causing the collision cutter head to reciprocate to impact the sludge in the pipeline.

[0011] A mobile walking mechanism is installed on the outer peripheral sidewall of the main body and is used to drive the main body to move.

[0012] Furthermore, the mobile walking mechanism includes at least three tracked wheels, which are distributed circumferentially along the main body, and each tracked wheel is mounted on the main body via an adjusting component.

[0013] Further, the adjusting component includes an adjusting seat, multiple pivot rods, an adjusting rod, and an adjusting slider; the adjusting seat is mounted on the outer peripheral sidewall of the main body, one end of each of the multiple pivot rods is pivotally connected to the outer sidewall of the adjusting seat, and the other end is pivotally connected to the mounting plate corresponding to the track wheel; the track wheel can swing relative to the main body; the adjusting seat has an adjusting screw, which extends along the sliding direction of the sliding rod; the adjusting screw is threadedly connected to the adjusting slider; one end of the adjusting rod is pivotally connected to the end of the adjusting slider away from the main body, and the other end is pivotally connected to the shaft of one of the pivot rods; the adjusting screw drives the adjusting slider to slide, thereby driving the adjusting rod to adjust the swing angle of the corresponding pivot rod, and thus adjusting the radial distance between the corresponding track wheel and the main body.

[0014] Furthermore, the adjusting component also includes an adjusting drive mechanism, which is mounted on the adjusting seat; the adjusting drive mechanism drives the adjusting lead screw.

[0015] Furthermore, the sliding rod is provided with a spray pipe extending along the axial direction of the sliding rod; a water inlet channel is provided at the end of the spray pipe away from the cutter head, and the water inlet channel passes through the sliding rod radially; a plurality of water nozzles are provided at the end of the spray pipe away from the connecting end, and the water nozzles extend away from the axis of the sliding rod and connect the spray pipe to the external environment; the plurality of water nozzles are distributed at intervals along the circumference and axial direction of the sliding rod.

[0016] Furthermore, the axis of the water nozzle forms an angle with the axis of the sliding rod, and the angle is 15°-75°.

[0017] Furthermore, the drainage pipe network dredging and cleaning equipment also includes a pressurizing component, which is installed in the installation space and has its inlet connected to the main water supply pipeline. The sludge softening nozzle and the water inlet channel are both connected to the outlet of the pressurizing component.

[0018] Furthermore, dustproof and wear-reducing sealing rings are provided at both ends of the through hole along its own axis, and wear-resistant bushings are embedded in the inner wall of the through hole; the wear-resistant bushings are located between the two dustproof and wear-reducing sealing rings.

[0020] Furthermore, a vision component is also installed on the front end face of the main body.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The collision component includes a collision cutter head and a sliding rod. The cutter head end of the sliding rod is connected to the collision cutter head, and the connecting end of the sliding rod slidably passes through a through hole. The end of the collision cutter head away from the sliding rod has a cutting edge. A reciprocating drive mechanism is installed in the installation space. The reciprocating drive mechanism drives the connecting end of the sliding rod to reciprocate along its own axis, thereby causing the collision cutter head to reciprocate and impact the sludge in the pipeline. Sliding the sliding rod inside the through hole can limit and guide the movement trajectory of the sliding rod, effectively preventing the sliding rod from deviating or wobbling during reciprocating motion. The reciprocating drive mechanism is located inside the installation space, making it less susceptible to corrosion from sewage and sludge in the pipeline, effectively extending its service life. The collision cutter head, relying on its cutting edge structure, can easily cut and break up clumps of sludge. Combined with the reciprocating impact operation mode, it can peel off the sludge adhering to the inner wall of the pipeline layer by layer, improving the cleaning efficiency of hard sludge in the pipeline.

[0023] 2. The sludge softening nozzle is installed on the front face of the main body and connected to the main water supply pipeline; the outlet of the sludge softening nozzle faces the area in front of the impact cutter head. The nozzle is fixed on the front face of the main body and forms a position with the impact cutter head, with the outlet facing the working area in front of the impact cutter head. This allows for pre-spraying and wetting of the sludge to be impacted and cleaned, quickly softening the dried sludge, reducing the adhesion between the sludge and the pipe wall, and reducing the workload generated during subsequent impact cleaning by the impact cutter head. This reduces the probability of wear and damage to the impact components, extends the overall service life of the equipment, and also increases the cleaning speed of stubborn sludge, achieving a dual function.

[0024] 3. The impact cutter head has a cutting edge at the end furthest from the sliding rod. The cutting edge of the impact cutter head has a certain cutting ability. In addition to breaking up and impacting silt, it can also cut and disperse small debris such as dead branches mixed in the pipeline, preventing debris from accumulating and clogging the pipeline.

[0025] 4. The mobile walking mechanism is installed on the outer perimeter of the main body to drive the main body to move. The mobile walking mechanism drives the entire equipment to move freely inside the drainage pipe network, switch working positions, and realize segmented dredging and cleaning operations along the entire pipe network. There is no need for manual repeated movement of the equipment, which improves the overall convenience of the equipment. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] See Figures 1-4 This utility model relates to a drainage pipe network dredging and cleaning device, comprising: a main body 1, a collision component 2, a sludge softening nozzle 3, a reciprocating drive mechanism 4, and a moving walking mechanism 5.

[0035] The main body 1 has an installation space 11, on which a main water supply pipe 12 is laid. The inlet end 121 of the main water supply pipe 12 passes through the rear end face 13 of the main body 1 and connects to an external water supply device. The front end face 14 of the main body 1 has a through hole 15, which connects the installation space 11 to the external environment. The main body 1 is the carrier of the entire drainage network dredging and cleaning equipment. The internal installation space 11 provides space for the installation of subsequent functional components. The main water supply pipe 12 is laid in the installation space 11 to avoid the pipes being messy and affecting the operation of the internal structure of the equipment. The inlet end 121 of the main water supply pipe 12 passes through the rear end face 13 of the main body 1 and connects to an external water supply device, which can stably receive external water sources and provide a continuous water flow for the equipment's sludge softening function.

[0036] The collision component 2 includes a collision cutter head 21 and a sliding rod 22; the cutter head end 221 of the sliding rod 22 is connected to the collision cutter head 21, and the connecting end 222 of the sliding rod 22 is slidably inserted through the through hole 15; the end of the collision cutter head 21 away from the sliding rod 22 has a cutting edge. The sliding rod 22 is a key component connecting the impact cutter head 21 and the main body 1. Its cutter head end 221 is connected to the impact cutter head 21 (e.g., a conical impact cutter head, a flat-mouth shovel cutter head, a multi-blade crushing cutter head, etc.). The connecting end 222 passes through the through hole 15 and can slide freely, ensuring that the impact cutter head 21 can extend out of the front end of the main body 1 to carry out sludge removal work. The blade of the impact cutter head 21 is used to directly impact the sludge in the pipeline. The sliding engagement of the sliding rod 22 can drive the impact cutter head 21 to move back and forth, so as to impact the sludge in different positions and destroy the integrity of the hard sludge. The sliding engagement design of the sliding rod 22 and the through hole 15 can not only ensure the reciprocating impact of the impact cutter head 21, but also avoid the impact of sliding jamming on the sludge removal efficiency. At the same time, the blade structure of the impact cutter head 21 can enhance the cleaning effect on stubborn sludge and improve the cleaning efficiency of hard sludge in the pipeline.

[0037] The sludge softening nozzle 3 is installed on the front end face 14 of the main body 1, and is connected to the main water supply pipeline 12. The outlet of the sludge softening nozzle 3 faces the front area of ​​the impact cutter head 21. The sludge softening nozzle 3 is fixedly installed on the front end face 14 of the main body 1. With the structure connected to the main water supply pipeline 12, it can directly obtain external water flow. Its outlet is aimed at the front area of ​​the impact cutter head 21, which can spray water flow into the sludge to be cleaned in advance before the impact cutter head 21 starts the impact cleaning operation. The water flow is used to wet and soften the dried and hardened sludge, reduce the overall hardness and adhesion strength of the sludge, thereby reducing the operating resistance encountered by the impact cutter head 21 during subsequent sludge cleaning. This can not only improve the overall dredging and cleaning efficiency, but also effectively reduce the wear generated by the impact cutter head 21 during operation, extend the overall service life of the impact component 2, play a dual role, and further improve the cleaning efficiency of hard sludge in the pipeline.

[0038] The reciprocating drive mechanism 4 is installed in the installation space 11. The reciprocating drive mechanism 4 drives the connecting end 222 of the sliding rod 22 to reciprocate along its own axis, thereby causing the collision cutter head 21 to reciprocate and impact the sludge in the pipeline. The reciprocating drive mechanism 4 is installed in the installation space 11 of the main body 1, which not only provides stable support to the main body 1, but also avoids exposure to the external pipeline environment and corrosion from sludge and sewage, thus extending the service life of the mechanism. Its drive connection with the connecting end 222 of the sliding rod 22 provides a stable power source for the sliding rod 22.

[0039] The mobile walking mechanism 5 is installed on the outer periphery of the main body 1 and is used to move the main body 1. It moves the entire equipment within the pipeline network, making it convenient to carry out dredging operations at different locations. Compared with fixed-position operation, the position of the equipment can be flexibly adjusted to adapt to the dredging needs of pipelines of different lengths and locations.

[0040] The working principle of this utility model of a drainage pipe network dredging and cleaning equipment is as follows: the moving walking mechanism 5 drives the entire equipment to move within the pipe network and reach the location that needs to be cleaned; the external water source provides water flow to the equipment through the main water supply pipeline 12, and the sludge softening nozzle 3 sprays water to soften the sludge in the pipe network and reduce its adhesion. During this process, the reciprocating drive mechanism 4 drives the sliding rod 22 to drive the collision cutter head 21 to reciprocate. The collision cutter head 21, with the help of its own structure and the inertia of the reciprocating motion, repeatedly impacts and breaks the softened sludge, separating the stubborn sludge from the pipe wall.

[0041] The collision component 2 includes a collision cutter head 21 and a sliding rod 22; the cutter end 221 of the sliding rod 22 is connected to the collision cutter head 21, and the connecting end 222 of the sliding rod 22 is slidably inserted through the through hole 15; the end of the collision cutter head 21 away from the sliding rod 22 has a cutting edge; the reciprocating drive mechanism 4 is installed in the installation space 11; the reciprocating drive mechanism 4 drives the connecting end 222 of the sliding rod 22, and the reciprocating drive mechanism 4 is used to drive the sliding rod 22 to reciprocate along its own axis, thereby causing the collision cutter head 21 to reciprocate to impact the sludge in the pipeline. The sliding rod 22 is slidably assembled inside the through hole 15, which can limit and guide the movement trajectory of the sliding rod 22, effectively preventing the sliding rod 22 from deviating and shaking during reciprocating motion; the reciprocating drive mechanism 4 is set inside the installation space 11, which is not easily corroded by sewage and sludge in the pipeline network, and can effectively extend its service life; the impact cutter head 21 can easily cut and break up the clump of sludge by means of the blade structure, and with the reciprocating impact operation mode, it can peel off the sludge attached to the inner wall of the pipeline network layer by layer, improving the cleaning efficiency of hard sludge in the pipeline.

[0042] The sludge softening nozzle 3 is installed on the front end face 14 of the main body 1 and is connected to the main water supply pipeline 12. The outlet of the sludge softening nozzle 3 faces the area in front of the impact cutter head 21. The nozzle is fixed on the front end face 14 of the main body 1 and forms a positional fit with the impact cutter head 21. The outlet faces the working area in front of the impact cutter head 21, which can spray and wet the sludge that is about to be impacted and cleaned in advance, quickly soften the dried sludge, reduce the adhesion between the sludge and the pipe wall, and reduce the working load generated when the impact cutter head 21 impacts and cleans. This can reduce the probability of wear and damage to the impact component 2, extend the overall service life of the equipment, and improve the cleaning speed of stubborn sludge, thus playing a dual role.

[0043] The impact cutter head 21 has a cutting edge at the end away from the sliding rod 22. The cutting edge of the impact cutter head 21 has a certain cutting ability. In addition to breaking and impacting silt, it can also cut and disperse small debris such as dead branches mixed in the pipeline, so as to prevent debris from accumulating and blocking the pipeline.

[0044] The mobile walking mechanism 5 is installed on the outer periphery of the main body 1 to drive the main body 1 to move. The mobile walking mechanism 5 drives the entire equipment to move freely inside the drainage pipe network, switch working positions, and realize segmented dredging and cleaning operations along the entire pipe network. This eliminates the need for repeated manual movement of the equipment and improves the overall convenience of the equipment.

[0045] Preferably, the mobile walking mechanism 5 includes at least three tracked wheels 51, which are distributed circumferentially around the main body 1, and each tracked wheel 51 is mounted on the main body 1 via an adjusting component 6. The circumferential distribution of at least three tracked wheels 51 around the main body 1 enables the equipment to obtain stable support at three or more points within the drainage pipe network, preventing lateral tilting during movement. The radial distance between each tracked wheel 51 and the main body 1 can be adjusted independently or in conjunction with the adjusting component 6 according to the inner diameter of the pipe, allowing the equipment to adapt to pipes of different diameters and ensuring that the tracked wheels 51 always maintain good contact and adhesion with the pipe wall. This improves the equipment's passability in complex pipe networks and provides a stable walking platform for collision dredging operations. Alternatively, the mobile walking mechanism 5 can also adopt a crawling walking structure other than wheeled walking components, magnetic walking components, and tracked walking components. The wheeled walking structure is simple in structure and has low traveling resistance, making it suitable for smooth movement inside pipe networks with flat inner walls. The magnetic walking structure can adhere to the pipe wall by means of adsorption force and can adapt to the operation scenario of inclined drainage pipe networks. The crawling walking structure is suitable for complex pipe network environments with uneven surfaces and a lot of debris, and has a stronger obstacle-crossing ability. All kinds of alternative structures can be stably installed on the outer peripheral side wall of the main body 1 and can all realize the basic function of driving the main body 1 to move as a whole. They can be flexibly replaced and selected according to different pipe network inner wall conditions, pipe routing, and on-site operation environment.

[0046] Preferably, the adjusting component 6 includes an adjusting seat 61, a plurality of pivot rods 62, an adjusting rod 63, and an adjusting slider 64. The adjusting seat 61 is mounted on the outer peripheral side wall of the main body 1. One end of each of the plurality of pivot rods 62 is pivotally connected to the outer side wall of the adjusting seat 61, and the other end is pivotally connected to the mounting plate 511 of the corresponding track wheel 51. The track wheel 51 can swing relative to the main body 1. The adjusting seat 61 has an adjusting screw 611, which extends along the sliding direction of the sliding rod 22. The adjusting screw 611 is threadedly connected to the adjusting slider 64. One end of the adjusting rod 63 is pivotally connected to the end of the adjusting slider 64 away from the main body 1, and the other end is pivotally connected to the rod body of one of the pivot rods 62. The adjusting screw 611 drives the adjusting slider 64 to slide, thereby driving the adjusting rod 63 to adjust the swing angle of the corresponding pivot rod 62, thereby adjusting the radial distance between the corresponding track wheel 51 and the main body 1. In simple terms, the swing of the adjusting rod 63 changes the swing angle of the pivot rod 62 relative to the adjusting seat 61. This change in the swing angle of the pivot rod 62 directly alters the relative position between the mounting plate 511 of the track wheel 51 and the adjusting seat 61, thereby changing the radial distance of the corresponding track wheel 51 relative to the main body 1. This allows the equipment to adapt to drainage pipe networks of different diameters, ensuring that the track wheel 51 always adheres to and presses firmly against the pipe wall, thus improving the stability of the equipment's movement and its adaptability to different pipe environments.

[0047] Preferably, the adjusting component 6 further includes an adjusting drive mechanism 65, which is mounted on the adjusting base 61; the adjusting drive mechanism 65 drives and connects to the adjusting lead screw 611. The adjusting drive mechanism 65, mounted on the adjusting base 61 and driving and connecting to the adjusting lead screw 611, enables automated or semi-automated control of the rotation of the adjusting lead screw 611. When the adjusting drive mechanism 65 outputs power, it directly drives the adjusting lead screw 611 to rotate, thereby driving the adjusting slider 64 to slide along the adjusting lead screw 611, ultimately achieving electric or pneumatic adjustment of the radial distance of the track wheel 51. This eliminates the need for manual rotation of the adjusting lead screw 611, thus improving the adaptability of the equipment when traveling in pipes of different diameters.

[0048] In addition, the extension and retraction of each adjusting component 6 can be adjusted individually. By utilizing the difference in the extension and retraction lengths of adjusting components 6 at different positions, the front end face 14 of the main body 1 is driven to rotate around the central axis of the pipe. This changes the working position and range of action of the impact cutter head 21, allowing the working area of ​​the impact cutter head 21 to gradually sweep along the circumference of the pipe. With this adjustment method, the impact cutter head 21 can act on hard sludge in different areas such as the bottom of the pipe and the sidewall of the pipe. At the same time, during operation or travel, the adjusting components 6 can also drive the track wheels 51 to retract, reducing the overall outer diameter of the equipment, making it easier for the wheels to pass through narrow pipe sections and obstacle areas after retraction.

[0049] Preferably, the sliding rod 22 is provided with a spray pipe 223, which extends along the axial direction of the sliding rod 22; the end of the spray pipe 223 away from the cutter head end 221 is provided with a water inlet channel 224, which penetrates the sliding rod 22 radially; the end of the spray pipe 223 away from the connection end 222 is provided with a plurality of water nozzles 225, which extend away from the axis of the sliding rod 22 and connect the spray pipe 223 to the external environment; the plurality of water nozzles 225 are distributed at intervals along the circumference and axial direction of the sliding rod 22. When the sliding rod 22 drives the impact cutter head 21 to reciprocate, these water nozzles 225 can spray water from the sides and front of the sliding rod 22 in multiple directions towards the sludge and pipe wall. On the one hand, this assists the sludge softening nozzle 3 in further wetting and softening the hard sludge. On the other hand, it can promptly flush away the mud after impact and breakage from the working area to prevent debris from accumulating and affecting the subsequent impact effect. At the same time, it can also flush and clean the gap between the sliding rod 22 and the through hole 15, reducing the risk of sludge particles entering the through hole 15 and causing sliding jamming.

[0050] Preferably, the axis of the nozzle 225 forms an angle with the axis of the sliding rod 22, with the angle being 15°-75°. When the angle is within the range of 15° to 75°, the water flow can simultaneously have a forward-propelling and lateral-spreading jet component, which can not only flush the sludge area to be cleaned in front of the impact cutter head 21, but also cover the pipe wall and sludge accumulation area on the side of the sliding rod 22; if the angle is less than 15°, the water flow is too close to the axis of the sliding rod 22, and the lateral flushing ability is insufficient, making it difficult to effectively clean the residual sludge attached to the pipe wall after the impact; if the angle is greater than 75°, the water flow is too biased to the lateral direction, and the forward-propelling ability is weakened, which is not conducive to delivering water to the deep sludge layer far away from the sliding rod 22.

[0051] In addition, a drainage network dredging and cleaning device also includes a pressurizing component 7, which is installed in the installation space 11. The inlet of the pressurizing component 7 is connected to the main water supply pipeline 12, and the sludge softening nozzle 3 and the inlet channel 224 are both connected to the outlet of the pressurizing component 7. The inlet of the pressurizing component 7 is connected to the main water supply pipeline 12, thereby obtaining water from the external water supply device from the main water supply pipeline 12. After pressurizing the water source, the pressurizing component 7 outputs a high-pressure water flow from its outlet. Since the inlet channel 224 in the sludge softening nozzle 3 and the sliding rod 22 are both connected to the outlet of the pressurizing component 7, the high-pressure water flow can be supplied to the spray pipe 223 in the sludge softening nozzle 3 and the sliding rod 22 simultaneously. The high-pressure water jet from the sludge softening nozzle 3 has stronger impact and penetrability, enabling it to more quickly wet, soften, and initially peel off hardened sludge, reducing the crushing force required when the impact cutter head 21 strikes. After entering the jet pipe 223 through the water inlet channel 224, the high-pressure water jet is ejected from multiple nozzles 225, which can efficiently flush away the mud after impact and crushing, and assist in cleaning the area around the sliding rod 22 and the impact cutter head 21.

[0052] Preferably, dustproof and friction-reducing sealing rings are provided at both ends of the through hole 15 along its own axis, and wear-resistant bushings are embedded in the inner wall of the through hole 15; the wear-resistant bushings are located between the two dustproof and friction-reducing sealing rings. The dustproof and friction-reducing sealing rings at both ends can prevent silt, sewage and solid particles in the external pipe network from entering the interior of the through hole 15, and at the same time reduce the frictional wear between the sliding rod 22 and the end of the through hole 15 during reciprocating motion; the wear-resistant bushing located between the two dustproof and friction-reducing sealing rings provides a sliding surface with a low coefficient of friction for the sliding rod 22, avoiding the sliding rod 22 from directly contacting the material of the body 1 (such as metal or plastic) and causing excessive wear. At the same time, the wear-resistant bushing can also guide the radial movement of the sliding rod 22, preventing the inner diameter of the through hole 15 from expanding or deforming due to long-term reciprocating motion.

[0053] Preferably, multiple through holes 15, impact cutter heads 21, and sliding rods 22 are provided, with each impact cutter head 21 corresponding to one sliding rod 22, and each sliding rod 22 corresponding to one through hole 15. The equipment can simultaneously perform reciprocating impact cleaning of hard sludge in the pipeline from multiple positions or directions. Each impact cutter head 21 is driven by its corresponding sliding rod 22, and each sliding rod 22 slides independently within its corresponding through hole 15. The sliding rods 22 do not interfere with each other and can reciprocate simultaneously, thereby achieving impact crushing of a larger area of ​​sludge layer within a unit time. Multiple impact cutter heads 21 can be distributed along the front end face 14 of the main body 1 in a certain pattern (e.g., uniformly distributed circumferentially or in an array). When the moving mechanism 5 drives the main body 1 to move along the pipeline, multiple impact cutter heads 21 can simultaneously act on different areas of the inner wall of the pipeline, avoiding the time consumption of a single cutter head repeatedly moving to cover the entire cross-section.

[0054] Preferably, the reciprocating drive mechanism 4 includes multiple integrated hydraulic cylinders, each corresponding to a specific connection end 222. Each sliding rod 22's connection end 222 is connected to an independent integrated hydraulic cylinder, and each impact cutter head 21 can reciprocate at the same or different frequencies, strokes, and phases. For example, all integrated hydraulic cylinders (e.g., hydraulic telescopic cylinders, miniature integrated hydraulic push rods, direct-pump integrated hydraulic cylinders, etc.) can synchronously drive their respective corresponding sliding rods 22, causing multiple impact cutter heads 21 to simultaneously impact the silt layer, producing a superimposed crushing effect; alternatively, an alternating drive method can be used, so that when some impact cutter heads 21 retract, other impact cutter heads 21 extend, thereby maintaining the force balance of the equipment in the pipeline and reducing the recoil vibration on the main body 1. Alternatively, the reciprocating drive mechanism 4 can be any one of a crank-connecting rod mechanism, a cylinder, or an electromagnetic linear oscillator. When the reciprocating drive mechanism 4 adopts a crank-connecting rod mechanism, the crank is driven to rotate by a motor, and the crank converts the rotational motion into the reciprocating linear motion of the sliding rod 22 along its own axis through the connecting rod. This is suitable for scenarios requiring a large stroke and a high impact frequency. When the reciprocating drive mechanism 4 adopts a cylinder, the piston is driven by the alternating intake and exhaust of compressed air to drive the connecting end 222 of the sliding rod 22 to reciprocate. This has the advantages of simple structure, fast response speed, and no electrical sparks, and is especially suitable for drainage pipe network environments with combustible gases. When the reciprocating drive mechanism 4 adopts an electromagnetic linear oscillator, the sliding rod 22 is directly driven to perform high-frequency small-amplitude reciprocating vibration by using an alternating electromagnetic field, which can achieve rapid micro-impact crushing of hard sludge.

[0055] Preferably, a vision component 8 is also installed on the front end face 14 of the main body 1. The vision component 8 (e.g., a high-definition waterproof camera, an infrared night vision camera assembly, a pipe endoscope, etc.) collects images of the internal environment of the pipeline network and the accumulation of sludge in real time, allowing external operators to intuitively grasp the on-site operation status, judge the progress of sludge removal and the remaining cleaning area, and facilitate timely adjustment of the equipment's movement position and sludge removal intensity. At the same time, it can clearly observe problems such as damage to the inner wall of the pipeline and potential blockages, assisting in the inspection of the internal condition of the pipeline network while completing the dredging and cleaning work.
