Description

Technical Field

[0001] This utility model relates to the technical field of dredging devices, specifically a tunnel drainage pipe probing and dredging device. Background Technology

[0002] Tunnel drainage pipes are specialized pipeline systems used in tunnel engineering to drain internal water, ensure the safety of the tunnel structure, and maintain a safe passage environment. They are a core component of the tunnel waterproofing and drainage system. Currently, the core structure of tunnel drainage pipe probing and dredging devices typically includes "probing body + dredging components". The probing body is usually a fixed cylindrical structure, while the dredging components are usually a single brush. The probing body is pushed into the pipe to complete the dredging operation.

[0003] In existing technologies, current tunnel drainage pipe dredging devices use brushes to clean the inner wall of the pipe. However, for stubborn silt that has a long adhesion time and strong adhesion, the cleaning force and contact depth of the brush alone are limited, making it difficult to completely remove the silt from the inner wall of the pipe. This results in some silt remaining on the inner wall of the pipe, which directly affects the overall dredging quality. At the same time, the probe body lacks a dedicated shock absorption structure during the movement of the pipe. In the operation of probing while simultaneously dredging, protrusions on the inner wall of the pipe, impacts from obstacles, or vibrations from the drive components are easily transmitted to the probe body, causing insufficient stability of the probe body and further reducing the dredging effect. Utility Model Content

[0004] The purpose of this utility model is to provide a tunnel drainage pipe probing and dredging device to solve the problems mentioned in the background art. The current tunnel drainage pipe dredging devices rely solely on brushing, which lacks sufficient force and depth to thoroughly remove stubborn silt that has been adhering for a long time and has strong adhesion, thus affecting the dredging quality. Furthermore, the probing body lacks a shock-absorbing structure, making it susceptible to impact and vibration during probing and dredging, which further reduces the dredging effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel drainage pipe probing and dredging device, comprising a frame, a movable component mounted on the frame, a drive unit mounted on the movable component, a rotating frame rotatably connected to one end of the frame, a first drive component mounted on the frame, a second drive component mounted on the rotating frame, a telescopic frame slidably connected to the rotating frame, a first universal joint fixedly connected to the same end of the frame and the rotating frame, a water inlet pipe with one end installed on one side of the first universal joint, a water storage cavity opened on the rotating frame, a first delivery pipe installed on the other side of the water storage cavity and the first universal joint, and a fixed connection. The system includes a second universal joint connected to the telescopic frame, a second delivery pipe installed between one side of the second universal joint and the water storage chamber, a hollow rod installed on the other side of the second universal joint, an abutment plate fixedly connected to one end of the hollow rod, a support frame and a high-pressure nozzle fixedly connected to the other end of the hollow rod, and a sludge removal strip fixedly connected to the outside of the support frame. The water inlet pipe is located inside the frame. The hollow rod is rotatably connected to the telescopic frame. The first drive assembly is used to drive the rotating frame to rotate and abuts against the inner wall of the pipe through the abutment plate, thereby driving the hollow rod to rotate. The second drive assembly is used to drive the telescopic frames on both sides to move closer or further apart.

[0006] In the preferred embodiment of this technical solution, the rotating frame has a groove at the corresponding position of the telescopic frame, and the telescopic frame is slidably connected to the groove of the rotating frame.

[0007] In a preferred embodiment of this technical solution, the first drive assembly includes a large gear fixedly connected to the rotating frame, a first motor fixedly connected inside the frame, and a small gear fixedly connected to the output end of the first motor. The small gear meshes with the large gear, and the first motor is used to drive the small gear to rotate.

[0008] In a preferred embodiment of this technical solution, the second drive assembly includes a second motor fixedly connected inside the rotating frame, a second bevel gear fixedly connected to the output end of the second motor, a bidirectional threaded rod rotatably connected to the rotating frame, and a first bevel gear fixedly connected to the bidirectional threaded rod at the position corresponding to the second bevel gear. The telescopic frame is threadedly connected to the bidirectional threaded rod, the first bevel gear meshes with the second bevel gear, and the second motor is used to drive the second bevel gear to rotate.

[0009] Based on the preferred embodiment of this technical solution, the length of the second conveying pipe is set to be sufficient to support the telescopic stroke of the telescopic frame.

[0010] In a preferred embodiment of this technical solution, the moving component includes a sliding frame slidably connected to the frame, a first movable support and a second movable support rotatably connected to the frame at one end, a moving wheel rotatably connected to the other end of the first movable support and the second movable support, a second rotating block rotatably connected to the sliding frame, a first rotating block rotatably connected to the moving wheel, a sliding frame slidably connected to the first rotating block, a damper fixedly connected between the sliding frame and the second rotating block, and a spring fixedly connected between the first rotating block and the second rotating block. The driving unit is used to drive the sliding frame to perform linear motion.

[0011] In a preferred embodiment of this technical solution, the first rotating block has a through groove at a corresponding position of the sliding frame, and the sliding frame is slidably connected to the through groove of the first rotating block.

[0012] In a preferred embodiment of this technical solution, the drive unit includes a hydraulic telescopic rod rotatably connected to the frame at one end, and a sliding frame fixedly connected to the telescopic end of the hydraulic telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The second drive assembly drives the two telescopic frames to move closer or further apart, allowing the two contact plates to stably contact the inner wall of the pipe. The first drive assembly then drives the rotating frame to rotate, and the friction patterns on the contact plates cause the hollow rod to rotate on the telescopic frame, which in turn causes the support frame and the outer sludge removal strip to rotate, thus physically scraping the inner wall of the pipe. At the same time, water is supplied to the water storage chamber of the rotating frame through the inlet pipe, the first universal joint, and the first delivery pipe, and then delivered to the hollow rod through the second delivery pipe and the second universal joint. Finally, high-pressure water is sprayed out by the high-pressure nozzle, which works synergistically with the sludge removal strip's rotation to significantly improve the sludge removal effect and facilitate the complete removal of sludge from the inner wall of the pipe.

[0015] 2. The drive unit drives the sliding frame to move linearly on the frame, which in turn moves the second rotating block. This, in turn, pulls the first rotating block via a damper and spring, adjusting the angle between the first and second movable supports, thus allowing for flexible adjustment of the moving wheel's position. This facilitates adaptation to pipes of different diameters, improving the device's adaptability. When the device encounters bumps or uneven sections within the pipe, the impact force on the moving wheel is transmitted to the spring and damper via the first rotating block. The spring initially buffers the impact force, while the damper absorbs vibration energy, preventing the impact force from being directly transmitted to the frame. This reduces frame vibration, ensures stable contact between the contact plate and the pipe wall, prevents the sludge removal strip from shifting due to vibration, and protects internal components, extending the device's service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Implementable methods already discovered in this field:

[0025] As a critical infrastructure in transportation, water conservancy, and municipal engineering, the long-term stable operation of tunnels directly depends on a robust waterproofing and drainage system. Tunnel drainage pipes are an indispensable core component of this system, playing a vital role in draining accumulated water from the tunnel interior and ensuring the structural safety and traffic environment of the tunnel. During tunnel operation, the sources of internal water accumulation are extremely complex. These include groundwater seeping from the surrounding rock—this water continuously seeps into the tunnel through pores or fissures in the rock strata. If not drained promptly, it gradually accumulates at the bottom or sidewalls of the tunnel, leading to an imbalance in surrounding rock pressure and subsequently causing cracks and corrosion in the tunnel lining structure; rainwater from the tunnel surface—especially during rainfall, if rainwater cannot drain quickly, it will accumulate inside the tunnel, affecting vehicle safety and increasing the risk of traffic accidents; and drainage from internal equipment, such as cooling drainage from ventilation and lighting equipment. Although this drainage is small in volume, it is continuously generated, and if it remains for a long time, it will erode the equipment base and the tunnel structure. Tunnel drainage pipes, through a rationally laid path, collect and transport accumulated water from various sources to the municipal drainage system or natural water bodies outside the tunnel. This fundamentally prevents water damage to the tunnel structure while maintaining a dry environment inside the tunnel, ensuring the safety and comfort of traffic. In long tunnels or tunnels with complex geological conditions, the role of tunnel drainage pipes is even more prominent. Their operational status directly determines the tunnel's lifespan and maintenance costs. Blockages in drainage pipes can not only lead to flooding inside the tunnel but also potentially cause more serious structural problems, such as increased water leakage in the lining and frost heave cracking of the road surface (in cold regions). Therefore, the unobstructed flow of tunnel drainage pipes is a crucial guarantee for the long-term stable operation of tunnel projects.

[0026] The structural design and laying method of tunnel drainage pipelines must be fully adapted to the engineering environment and drainage needs of the tunnel. Common structural forms and laying requirements revolve around three core objectives: "efficient drainage, stable operation, and easy maintenance." Structurally, tunnel drainage pipelines mostly use circular or rectangular cross-sections. Circular pipes are the most widely used in most tunnel projects due to their advantages such as low flow resistance, strong compressive strength, and resistance to siltation. Rectangular pipes are often used under tunnel maintenance passages or in narrow spaces on side walls, where they can make full use of limited space and adapt to special installation environments. Regarding material selection, early tunnel drainage pipelines mostly used reinforced concrete pipes. While these pipes were low-cost and had high compressive strength, they were heavy, difficult to install, and susceptible to groundwater corrosion. With the development of materials technology, today's tunnel drainage pipelines increasingly use high-density polyethylene (HDPE) pipes, polypropylene (PP) pipes, and other plastic pipes. These pipes are lightweight, corrosion-resistant, have smooth inner walls that prevent siltation, and are easy to install, effectively improving the service life and drainage efficiency of the drainage pipelines while reducing the difficulty of later maintenance. In terms of laying method, the laying path of tunnel drainage pipes needs to be determined in combination with the cross-sectional structure of the tunnel and the characteristics of water accumulation distribution. They are usually laid along the bottom of the tunnel sidewall, below the maintenance passage, or at the top of the tunnel: When laid along the bottom of the sidewall, the pipe is close to the road surface, which is convenient for collecting rainwater from the road surface and seepage water from the sidewall, and there is no need to excavate the road surface for later maintenance, making the operation convenient; when laid below the maintenance passage, the pipe is shielded by the maintenance passage, which can effectively avoid accidental vehicle collisions or damage to the pipe from the external environment, while not occupying the passage space inside the tunnel; laying along the top of the tunnel is mostly used in water conservancy tunnels or special purpose tunnels, mainly to drain seepage water from the surrounding rock at the top of the tunnel and prevent dripping water from the top from affecting the operation of equipment inside the tunnel. Furthermore, to ensure smooth drainage, the laying of tunnel drainage pipes must strictly adhere to a preset slope, typically no less than 0.3%, to guarantee sufficient flow velocity and prevent water stagnation and accumulation within the pipes. For long tunnels exceeding 1000 meters in length, a tiered drainage system of "main pipe + branch pipes" is implemented. Branch pipes are installed at intervals (usually 50-100 meters) along the tunnel's longitudinal direction to collect water from localized areas. This water then flows into the main pipe via connecting pipes, ultimately draining the water out of the tunnel. This tiered drainage system effectively improves drainage efficiency and prevents water accumulation caused by insufficient drainage capacity of a single pipe. Additionally, inspection ports and manholes are installed at regular intervals (usually 200-300 meters) along the tunnel drainage pipes. Inspection ports allow personnel and equipment access during pipe dredging and maintenance, while manholes are used to observe water flow and water levels within the pipes, facilitating timely detection of blockages or leaks.

[0027] Although tunnel drainage pipes are designed and laid with silt prevention and drainage efficiency fully considered, they still face a high risk of blockage during long-term operation. These risks mainly stem from the continuous accumulation of silt and debris within the pipes. If not cleaned promptly, this will severely affect the drainage function of the pipes, thereby threatening the structural safety of the tunnel. The sources of blockages in tunnel drainage pipes mainly fall into three categories: The first is silt and soil particles, primarily from seepage water from the surrounding rock of the tunnel. This seepage water carries a small amount of silt as it flows through the rock strata. This silt, after entering the drainage pipes, gradually settles at the bottom of the pipes due to the reduced flow velocity, accumulating over time to form a silt layer. The second category is road debris, such as gravel, dust, leaves, and garbage dropped by vehicles. This debris, after entering the drainage pipes with rainwater, can become stuck directly at pipe joints or bends, causing blockages. The first type of blockage is caused by the accumulation of sediment around the blockage point, exacerbating the blockage. The second type involves the deposition of biological or chemical substances within the pipes. In warm, humid environments, microorganisms or algae can proliferate inside the pipes, forming a biofilm that adheres to the inner wall. This biofilm further absorbs sediment and debris, gradually thickening to form a stubborn blockage layer. Additionally, if industrial wastewater seeps into the tunnel, the chemicals in the wastewater may react with the water flow, forming sediments that also adhere to the inner wall and are difficult to remove. This accumulation of blockages not only reduces the pipe's diameter and drainage capacity but also creates localized water accumulation, which continuously erodes the pipe's inner wall, shortening its lifespan. In severe cases, the pipe may become completely blocked, preventing water from draining from the tunnel and causing problems such as road flooding and increased leakage from side walls. In serious cases, this can affect normal tunnel traffic and even lead to safety accidents. Therefore, regular dredging of tunnel drainage pipes is essential to ensure the normal operation of the tunnel drainage system and maintain the structural safety of the tunnel. However, dredging operations in tunnel drainage pipes face numerous challenges: Firstly, tunnel drainage pipes are often located beneath tunnel sidewalls or maintenance passages, resulting in narrow working spaces that make it difficult for traditional large-scale dredging equipment to access, thus increasing the difficulty of dredging operations. Secondly, the blockages within the pipes are complex, containing both loose mud and sand as well as stubborn hardened silt and biofilm, making it difficult to completely remove them using a single dredging method, resulting in low dredging efficiency. Furthermore, dredging operations in tunnel drainage pipes typically need to be carried out during tunnel operation breaks, limiting working time and placing higher demands on the efficiency and convenience of dredging equipment. Based on these challenges, developing efficient, convenient, and adaptable tunnel drainage pipe dredging devices that can adapt to the complex environment of tunnels has become a key requirement for solving the problem of blockages in tunnel drainage pipes and ensuring the long-term stable operation of tunnels.

[0028] Please see Figure 1-6This utility model provides an embodiment of a tunnel drainage pipe probing and dredging device, including a frame 1, a movable component mounted on the frame 1, a drive unit mounted on the movable component, a rotating frame 21 rotatably connected to one end of the frame 1, a first drive component mounted on the frame 1, a second drive component mounted on the rotating frame 21, a telescopic frame 211 slidably connected to the rotating frame 21, a first universal joint 25 fixedly connected to the same end of the frame 1 and the rotating frame 21, a water inlet pipe 26 with one end installed on one side of the first universal joint 25, and a device opened on the rotating frame 21. Water storage chamber 24, first delivery pipe 27 installed on the other side of water storage chamber 24 and first universal joint 25, second universal joint 214 fixedly connected to telescopic frame 211, second delivery pipe 215 installed between one side of second universal joint 214 and water storage chamber 24, hollow rod 217 installed on the other side of second universal joint 214, contact plate 216 fixedly connected to one end of hollow rod 217, support frame 218 fixedly connected to the other end of hollow rod 217 and high pressure nozzle 220, and sludge removal hanging strip 219 fixedly connected to the outside of support frame 218, water inlet pipe 2 6 is installed inside the frame 1. The hollow rod 217 is rotatably connected to the telescopic frame 211. The first drive assembly is used to drive the rotating frame 21 to rotate, and it abuts against the inner wall of the pipe through the contact plate 216, thereby driving the hollow rod 217 to rotate. The second drive assembly is used to drive the telescopic frames 211 on both sides to move closer or further apart. By driving the telescopic frames 211 on both sides to move closer or further apart through the second drive assembly, the contact plates 216 on both sides can stably abut against the inner wall of the pipe. Then, the first drive assembly drives the rotating frame 21 to rotate, which cooperates with the friction texture on the contact plate 216. The road can drive the hollow rod 217 to rotate on the telescopic frame 211, which in turn drives the support frame 218 and the outer sludge removal strip 219 to rotate, thus physically scraping the inner wall of the pipe. At the same time, water is supplied to the water storage chamber 24 of the rotating frame 21 through the water inlet pipe 26, the first universal joint 25, and the first delivery pipe 27, and then transported to the hollow rod 217 through the second delivery pipe 215 and the second universal joint 214. Finally, high-pressure water is sprayed out by the high-pressure nozzle 220, which works synergistically with the sludge removal of the sludge removal strip 219 to significantly improve the sludge removal effect of the pipe and facilitate the complete removal of sludge from the inner wall of the pipe.

[0029] Please see Figure 2A further solution based on this embodiment is as follows: the rotating frame 21 has a groove at the corresponding position of the telescopic frame 211, and the telescopic frame 211 is slidably connected to the groove of the rotating frame 21. By opening the groove on the rotating frame 21 at the position corresponding to the telescopic frame 211, a clear guiding path can be provided for the sliding of the telescopic frame 211, avoiding lateral deviation of the telescopic frame 211 when it approaches or moves away from the inner wall of the pipe; at the same time, the groove can restrict the movement direction of the telescopic frame 211, so that the telescopic frame 211 always slides along the preset trajectory, ensuring that the telescopic frames 211 on both sides drive the contact plate 216 to move closer or further away at the same time, making the contact force between the contact plate 216 and the inner wall of the pipe more uniform, thereby ensuring the stability of the hollow rod 217 when it rotates, avoiding the sludge removal strip 219 from shifting its position due to the shaking of the hollow rod 217, and improving the accuracy of the sludge removal operation.

[0030] Please see Figure 3 A further solution based on this embodiment is as follows: The first drive assembly includes a large gear 28 fixedly connected to the rotating frame 21, a first motor 22 fixedly connected inside the frame 1, and a small gear 23 fixedly connected to the output end of the first motor 22. The small gear 23 meshes with the large gear 28. The first motor 22 is used to drive the small gear 23 to rotate. By driving the small gear 23 at the output end of the first motor 22 to rotate, the power of the first motor 22 can be stably transmitted to the rotating frame 21 through the meshing transmission of the small gear 23 and the large gear 28 on the rotating frame 21, causing the rotating frame 21 to rotate at a preset speed. The gear transmission has the characteristics of high transmission efficiency and stable torque transmission, which can avoid slippage or power loss during power transmission, ensuring that the rotation speed of the rotating frame 21 is uniform. Then, through the friction between the contact plate 216 and the inner wall of the pipe, the hollow rod 217 is driven to rotate stably, so that the scraping speed of the sludge removal strip 219 is consistent, which improves the scraping effect on the sludge of the inner wall of the pipe.

[0031] Please see Figure 2A further embodiment of this solution is as follows: The second drive assembly includes a second motor 210 fixedly connected inside the rotating frame 21, a second bevel gear 213 fixedly connected to the output end of the second motor 210, a bidirectional threaded rod 29 rotatably connected to the rotating frame 21, and a first bevel gear 212 fixedly connected to the bidirectional threaded rod 29 at the position corresponding to the second bevel gear 213. The telescopic frame 211 is threadedly connected to the bidirectional threaded rod 29. The first bevel gear 212 meshes with the second bevel gear 213. The second motor 210 is used to drive the second bevel gear 213 to rotate. By driving the second bevel gear 213 to rotate through the second motor 210, the second bevel gear 213 meshes with the bidirectional threaded rod 29. The meshing of the first bevel gear 212 drives the bidirectional threaded rod 29 to rotate stably. Since the telescopic frame 211 is threadedly connected to the bidirectional threaded rod 29, the rotation of the bidirectional threaded rod 29 can be converted into synchronous linear motion of the telescopic frames 211 on both sides, so that the telescopic frames 211 on both sides can move closer or further apart. The bevel gear transmission structure is compact and suitable for the limited space inside the rotating frame 21. The bidirectional threaded rod 29 can ensure that the telescopic amount of the telescopic frames 211 on both sides is completely consistent, so that the contact force between the contact plates 216 on both sides and the inner wall of the pipe is the same. This avoids the hollow rod 217 from being unstable due to insufficient contact force on one side, or the inner wall of the pipe from being damaged by excessive contact force on one side. At the same time, it can also accurately adapt to pipes of different diameters and improve the versatility of the device.

[0032] Please see Figure 2 A further solution based on this embodiment is as follows: the length of the second conveying pipe 215 is set to be sufficient to support the extension and retraction stroke of the telescopic frame 211. By setting the length of the second conveying pipe 215 to be sufficient to support the extension and retraction stroke of the telescopic frame 211, it can be ensured that when the telescopic frame 211 moves within its maximum extension and retraction range, the second conveying pipe 215 will not be pulled and broken due to insufficient length, nor will it be entangled due to excessive looseness. This design can ensure that the water supply passage between the water storage chamber 24 and the second universal joint 214 is always unobstructed, allowing the high-pressure nozzle 220 to continuously obtain a stable water supply, avoiding water supply interruption due to the movement of the telescopic frame 211, thereby ensuring that the self-rotation scraping of the dredging strip 219 and the water spraying and rinsing of the high-pressure nozzle 220 are always coordinated, without any interruption in the dredging operation, thus improving the overall dredging efficiency.

[0033] Please see Figure 5A further solution based on this embodiment is as follows: the moving component includes a sliding frame 32 slidably connected to the frame 1, a first movable support 33 and a second movable support 35 rotatably connected to the frame 1 at one end, a moving wheel 34 rotatably connected to the other end of the first movable support 33 and the second movable support 35, a second rotating block 37 rotatably connected to the sliding frame 32, a first rotating block 36 rotatably connected to the moving wheel 34, a sliding frame 39 slidably connected to the first rotating block 36, a damper 38 fixedly connected between the sliding frame 39 and the second rotating block 37, and a spring 310 fixedly connected between the first rotating block 36 and the second rotating block 37. The driving unit is used to drive the sliding frame 32 to perform linear motion. By driving the sliding frame 32 to perform linear motion on the frame 1 through the driving unit, the first rotating block 36 can be driven to perform linear motion on the frame 1. The second rotating block 37 moves, which in turn pulls the first rotating block 36 through the damper 38 and the spring 310, adjusting the angle between the first movable support 33 and the second movable support 35, thus flexibly adjusting the position of the moving wheel 34. This facilitates adaptation to pipes of different diameters, improving the adaptability of the device. When the device encounters protrusions or uneven sections in the pipe, the impact force on the moving wheel 34 is transmitted to the spring 310 and the damper 38 through the first rotating block 36. The spring 310 can initially buffer the impact force, while the damper 38 can absorb the vibration energy, preventing the impact force from being directly transmitted to the frame 1. This reduces the vibration of the frame 1, ensures stable contact between the contact plate 216 and the inner wall of the pipe, prevents the sludge removal strip 219 from deviating from the scraping position due to vibration, and also protects the internal components of the device, extending its service life.

[0034] Please see Figure 6 A further solution based on this embodiment is as follows: the first rotating block 36 has a through groove at the corresponding position of the sliding frame 39, and the sliding frame 39 is slidably connected to the through groove of the first rotating block 36. By opening a through groove at the position of the first rotating block 36 corresponding to the sliding frame 39, and allowing the sliding frame 39 to be slidably connected to the through groove, the shock absorption effect of the moving component and the telescopic driving effect of the second driving component do not interfere with each other, ensuring that the device can stably absorb shock during the exploration process, and can flexibly adjust the position of the telescopic frame 211 to adapt to the pipe diameter, thus ensuring the continuity of the dredging operation.

[0035] Please see Figure 5A further solution based on this embodiment is as follows: The drive unit includes a hydraulic telescopic rod 31 with one end rotatably connected to the frame 1, and a sliding frame 32 fixedly connected to the telescopic end of the hydraulic telescopic rod 31. By using the hydraulic telescopic rod 31 with one end rotatably connected to the frame 1 as the drive unit, and fixing the sliding frame 32 to its telescopic end, the extension and retraction of the hydraulic telescopic rod 31 can stably push the sliding frame 32 to move linearly on the frame 1. The hydraulic drive has the characteristics of large driving force, smooth movement and strong controllability. It can accurately adjust the moving distance of the sliding frame 32 according to the actual situation in the pipeline, and then accurately control the position and angle of the moving wheel 34 through the moving component, so that the device can flexibly adapt to different road conditions in the pipeline. At the same time, the rotational connection design of the hydraulic telescopic rod 31 can avoid the additional stress generated by the angle change when driving the sliding frame 32, extend the service life of the drive unit, and ensure that the moving component can continuously and stably realize the functions of shock absorption and attitude adjustment.

[0036] Working principle: First, the drive unit (hydraulic telescopic rod 31) is started. Its telescopic end pushes the sliding frame 32 to move linearly on the frame 1. The sliding frame 32 drives the second rotating block 37 to move, and then pulls the first rotating block 36 through the damper 38 and the spring 310, adjusting the angle between the first movable support 33 and the second movable support 35, so that the moving wheel 34 fits against the inner wall of the pipe, which is convenient for adapting to pipes of different diameters and improving the adaptability of the dredging device. At the same time, the spring 310 and the damper 38 in the moving assembly can buffer the vibration in subsequent operations. Then, the second drive assembly is started. The second motor 210 drives the second bevel gear 213 to rotate. Through meshing with the first bevel gear 212 on the bidirectional threaded rod 29, the bidirectional threaded rod 29 is driven to rotate. The bidirectional threaded rod 29 drives the telescopic frames 211 on both sides to slide along the slide groove of the rotating frame 21, moving closer or further away from each other until the contact plate 216 stably contacts the inner wall of the pipe, completing the pipe diameter adaptation and dredging positioning. Then, the first drive assembly is started. The first motor 22 drives the small gear 23 to rotate. The small gear 23 meshes with the large gear 28 on the rotating frame 21, causing the rotating frame 21 to rotate. The contact plate 216, due to friction with the inner wall of the pipe, causes the hollow rod 217 to rotate on the telescopic frame 211. The support frame 218 at the other end of the hollow rod 217 and the outer sludge removal hanging strip 219 rotate synchronously. At the same time, a water pump is externally connected to the water source through one end of the water inlet pipe 26, and water is then transported to the rotating frame 211 through the first universal joint 25 and the first delivery pipe 27. The water in the storage chamber 24 of the frame 21 flows through the second delivery pipe 215 (the length of which is adapted to the travel of the telescopic frame 211 to ensure smooth water delivery) and the second universal joint 214 into the hollow rod 217, and finally sprays high-pressure water from the high-pressure nozzle 220. This works in conjunction with the self-rotating scraping action of the sludge removal strip 219 to thoroughly clean the sludge inside the pipe. Throughout the process, the moving wheel 34 is controlled by an external controller to drive the entire device to probe into the inside of the pipe, improving its practicality.
