Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.
[0003] Existing trenchless pipeline cleaning devices include spray branch pipes, high-pressure spray heads, spray main pipes, fixed bases, wire cleaning brushes, and connecting rods. A first support plate is mounted on the left side of the upper surface of the fixed base, and a second support plate is mounted on the right side. A spray main pipe runs horizontally through the upper side of the first support plate. A spray branch pipe is mounted on the left side of the annular side of the spray main pipe, and a high-pressure spray head is mounted on the outer end of the spray branch pipe. A travel drive device is mounted on the upper side of the fixed base, and a high-pressure water pump is located on the left side of the travel drive device. An inlet pipe is installed at the connection between the high-pressure water pump and the spray main pipe. Travel wheels are mounted on the front and rear sides of the fixed base. A drive motor is mounted on the left side of the first support plate, and a transmission shaft is mounted on the right side of the drive motor. A fixed mounting sleeve is mounted on the right side of the annular side of the transmission shaft, and a connecting rod is mounted on the annular side of the fixed mounting sleeve. A wire cleaning brush is mounted on the outer end of the connecting rod. Upper protective baffles are mounted on the upper sides of the first and second support plates. However, existing trenchless pipeline cleaning devices cannot adapt to pipes of different diameters, resulting in poor versatility. Utility Model Content
[0004] To address the issue that existing trenchless pipe cleaning devices cannot be adapted to pipes of different diameters, this application provides a highly adaptable trenchless pipe cleaning device.
[0005] This application provides a highly adaptable trenchless pipeline inner wall cleaning device, which adopts the following technical solution:
[0006] A highly adaptable trenchless pipeline cleaning device includes a base and a housing. The bottom of the housing is open, and the base covers the opening to form a receiving cavity. A cleaning component for cleaning dirt inside the pipeline is installed within the receiving cavity. The cleaning component includes a drive motor and a mounting sleeve. The drive motor is fixedly mounted on the side wall inside the receiving cavity, and its shaft passes through the side wall and is located outside the housing. The mounting sleeve is fixedly mounted on the drive motor's shaft. Multiple connecting rods are provided on the peripheral side wall of the mounting sleeve, and a wire cleaning brush for cleaning the pipeline's inner wall is installed at the end of each connecting rod away from the mounting sleeve. An adjustment component for adjusting the length of each connecting rod is provided on the connecting rod.
[0007] By adopting the above technical solution, when cleaning pipes of different diameters is required, the length of the connecting support rod can be changed by adjusting the component, allowing the wire cleaning brush to adapt to the inner walls of pipes of different diameters. Specifically, adjusting the length of the connecting support rod adjusts the extension range of the wire cleaning brush inside the pipe, ensuring close contact between the wire cleaning brush and the inner wall of the pipe, thereby effectively removing dirt from the inner wall of the pipe. This design makes the device no longer limited to pipes of a specific diameter, and can adapt to the cleaning needs of various pipe specifications, improving the versatility and practicality of the device.
[0008] Preferably, the connecting support rod includes a main rod, an auxiliary rod, and an adjusting rod. The main rod and the auxiliary rod have the same diameter. One end of the auxiliary rod is fixedly connected to the mounting sleeve. The main rod is located on the side of the auxiliary rod away from the main rod. The adjusting rod is located between the main rod and the auxiliary rod. One end of the adjusting rod is embedded in the end of the auxiliary rod away from the mounting sleeve and is fixedly connected to the auxiliary rod. The end of the adjusting rod away from the auxiliary rod is slidably engaged with the main rod.
[0009] By adopting the above technical solution, the combination of the main rod, auxiliary rod, and adjusting rod forms a telescopic connection structure. The auxiliary rod is fixedly connected to the mounting sleeve, providing a stable installation foundation for the entire connecting support. One end of the adjusting rod is fixed to the auxiliary rod, while the other end slides with the main rod, allowing the main rod to slide along the length of the adjusting rod, thereby adjusting the length of the connecting support. This structural design is simple and reliable, enabling convenient length adjustment while ensuring connection strength to accommodate pipes of different diameters.
[0010] Preferably, the adjusting assembly includes a limiting plate and a base plate. The base plate is fixedly installed on the side wall of the main rod. A pin is passed through the limiting plate, and the limiting plate and the base plate are hinged by the pin. A torsion spring is sleeved on the pin. A horizontal plate is provided at one end of the limiting plate. A square hole for inserting the horizontal plate is provided on the main rod. Multiple fixing holes are provided along the length direction on the side wall of the adjusting rod near the square hole. The multiple fixing holes are spaced apart along the length direction of the adjusting rod.
[0011] By employing the above technical solution, the adjustment assembly, through the cooperation of a limiting plate, a base plate, a pin, and a torsion spring, achieves the limiting and fixing of the adjustment rod. In its natural state, the restoring force of the torsion spring causes the horizontal plate on the limiting plate to insert into the square hole of the main rod and the fixing hole of the adjustment rod, thereby fixing the position of the adjustment rod and ensuring the stability of the connecting rod's length. When length adjustment is required, the operator only needs to manually apply external force to disengage the horizontal plate from the fixing hole and square hole, allowing the main rod to slide and adjust the length. After adjustment, releasing the external force will automatically re-insert the horizontal plate into the corresponding fixing hole and square hole, achieving quick locking. This adjustment method is simple to operate, reliable in locking, and maintains the stability of the connecting rod's length during cleaning, ensuring effective cleaning.
[0012] Preferably, the top surface of the base has a sealing groove that matches the bottom of the chassis, and a sealing gasket is provided in the sealing groove. The chassis is inserted into the sealing groove on the side near the bottom. The outer wall of the chassis is provided with multiple connecting blocks, which are evenly distributed around the chassis and located on the side of the chassis near the bottom. Bolts are provided through each of the multiple connecting blocks, and the chassis and the base are connected by bolt threads.
[0013] By adopting the above technical solution, the sealing groove and sealing gasket on the base effectively prevent leakage of liquid or dust from the receiving cavity, ensuring the normal working environment of all components within the cavity. The chassis is fixedly connected to the base via connecting blocks and bolts. This connection method is not only structurally robust but also facilitates installation and disassembly, making it convenient for maintenance and repair of the components within the receiving cavity. Multiple connecting blocks are evenly distributed around the chassis, ensuring a more uniform and stable connection between the chassis and the base, thus improving the overall structural strength of the device.
[0014] Preferably, the bottom surface of the base is provided with a plurality of wheels, and the receiving cavity is provided with a driving device for driving the wheels.
[0015] By adopting the above technical solution, the walking drive device drives the walking wheels to rotate, enabling the device to move autonomously inside the pipeline without manual pushing, reducing the labor intensity of operators and improving the automation level of cleaning operations.
[0016] Preferably, the water spray assembly includes a high-pressure water pump, an inlet pipe, and a high-pressure nozzle. The high-pressure water pump is fixedly installed on the top surface of the base and located inside the receiving cavity. The high-pressure water pump is located on the side of the receiving cavity away from the drive motor. One end of the inlet pipe is fixedly connected to the outlet end of the high-pressure water pump. The end of the inlet pipe away from the high-pressure water pump passes through the side wall of the receiving cavity and is located outside the housing. Multiple water spray branch pipes are provided at the end of the inlet pipe away from the high-pressure water pump. The multiple water spray branch pipes are arranged vertically around the periphery of the inlet pipe at intervals.
[0017] By adopting the above technical solution, the water spray assembly can spray high-pressure water into the pipe during cleaning, thus assisting in the cleaning process. A high-pressure water pump pressurizes the water and delivers it through the inlet pipe to the spray branch pipes and high-pressure nozzles. Multiple spray branch pipes are arranged at intervals around the inlet pipe, ensuring that the high-pressure water is evenly sprayed onto all parts of the pipe's inner wall, flushing it, softening or removing stubborn dirt. Combined with the mechanical cleaning of the wire brush, this improves cleaning efficiency and effectiveness. Simultaneously, the high-pressure water also provides cooling and lubrication, reducing friction between the wire brush and the pipe's inner wall and extending the device's lifespan.
[0018] Preferably, the cleaning assembly further includes a drive spindle. A through hole is provided on the side wall of the receiving cavity near the drive motor. A drive bearing is fixedly installed in the through hole. The drive spindle is disposed inside the drive bearing. The shaft of the drive motor is fixedly connected to one end of the drive spindle. The end of the drive spindle away from the drive motor passes through the drive bearing and is located outside the housing. The mounting sleeve is fixedly installed on the end of the drive spindle away from the drive motor.
[0019] By adopting the above technical solution, the drive spindle can transmit the power of the drive motor to the mounting sleeve and the wire cleaning brush, enabling the wire cleaning brush to rotate at high speed, thereby effectively cleaning the inner wall of the pipe. The drive bearing is installed in the through hole of the receiving cavity, which reduces the frictional resistance during the rotation of the drive spindle, making the rotation smoother, and improving the support strength and stability of the drive spindle. The drive motor shaft is fixedly connected to the drive spindle, ensuring reliable power transmission and guaranteeing the rotation speed and cleaning effect of the wire cleaning brush.
[0020] Preferably, the plurality of connecting rods are arranged vertically at intervals around the periphery of the mounting sleeve.
[0021] By adopting the above technical solution, multiple connecting rods are arranged vertically around the periphery of the mounting sleeve at intervals, enabling the wire cleaning brush to form a uniform circumferential distribution inside the pipe. This allows for comprehensive contact with all parts of the pipe's inner wall during rotation, ensuring that every area of the pipe's inner wall is cleaned, thus improving the thoroughness and uniformity of the cleaning. This arrangement also ensures that the wire cleaning brush receives uniform force during rotation, reducing device vibration and improving the device's operational stability.
[0022] Preferably, the main rod, auxiliary rod, and adjusting rod are all rectangular square tubes, and one end of the adjusting rod that slides into the main rod is embedded in the main rod.
[0023] By adopting the above technical solution, the main rod, auxiliary rod, and adjusting rod are constructed using rectangular tubing, which improves the structural strength and rigidity of the connecting rod. This allows it to withstand the friction and impact forces between the wire brush and the inner wall of the pipe during cleaning, preventing deformation or damage. The sliding fit of the adjusting rod, embedded within the main rod, ensures smoother sliding between the main rod and the adjusting rod, while reducing the possibility of dust and debris entering the connecting rod, thus guaranteeing its normal sliding and adjustment.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. When cleaning pipes of different diameters, the length of the connecting rod can be changed by adjusting the component, allowing the wire cleaning brush to adapt to the inner wall of pipes of different diameters. Specifically, adjusting the length of the connecting rod can adjust the extension range of the wire cleaning brush inside the pipe, ensuring that the wire cleaning brush is in close contact with the inner wall of the pipe, thereby effectively removing dirt from the inner wall of the pipe. This design makes the device no longer limited to pipes of a specific diameter, and can adapt to the cleaning needs of various specifications of pipes, improving the versatility and practicality of the device.
[0026] 2. The adjustment assembly, through the cooperation of a limiting plate, a base plate, a pin, and a torsion spring, achieves the limiting and fixing of the adjustment rod. In its natural state, the restoring force of the torsion spring causes the horizontal plate on the limiting plate to insert into the square hole of the main rod and the fixing hole of the adjustment rod, thereby fixing the position of the adjustment rod and ensuring the stability of the length of the connecting rod. When the length needs to be adjusted, the operator only needs to manually apply external force to disengage the horizontal plate from the fixing hole and the square hole, and then slide the main rod to adjust the length. After the adjustment is completed, the external force is released, and the torsion spring will automatically re-insert the horizontal plate into the corresponding fixing hole and square hole, achieving quick locking. This adjustment method is simple to operate, reliable in locking, and can maintain the stability of the length of the connecting rod during the cleaning process, ensuring the cleaning effect.
[0027] 3. The water spray assembly enables the spraying of high-pressure water into the pipes during cleaning, thus aiding in the cleaning process. A high-pressure water pump pressurizes the water and delivers it through the inlet pipe to the spray branch pipes and high-pressure nozzles. Multiple spray branch pipes are spaced apart around the inlet pipe, ensuring that the high-pressure water is evenly sprayed onto all parts of the pipe's inner wall, flushing, softening, or removing stubborn dirt. Combined with the mechanical cleaning of the wire brush, this improves cleaning efficiency and effectiveness. Simultaneously, the high-pressure water also provides cooling and lubrication, reducing friction between the wire brush and the pipe's inner wall and extending the device's lifespan.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0035] This application discloses a highly adaptable trenchless pipe wall cleaning device.
[0036] Reference Figure 1 and Figure 2A highly adaptable trenchless pipe cleaning device includes a base 1 and a housing 2. The housing 2 is fixedly installed on the top surface of the base 1. The housing 2 is equipped with a water spraying component 3 for spraying water into the pipe and a cleaning component 4 for cleaning dirt from the pipe. The bottom of the base 1 is equipped with multiple wheels 5, and the housing 2 is also equipped with a driving device 6 for driving the wheels 5.
[0037] The chassis 2 has an opening on one side at the bottom. The base 1 covers the opening at the bottom of the chassis 2, forming a receiving cavity 7. The chassis 2 and the base 1 are fixedly connected. The walking drive device 6 is fixedly installed in the receiving cavity 7. The base 1 has a sealing groove 8 that matches the bottom of the chassis 2, and a sealing gasket 9 is placed in the sealing groove 8. During installation, the chassis 2 is inserted into the sealing groove 8 on one side at the bottom, and abuts against the sealing gasket 9. Multiple connecting blocks 10 are provided on the outer wall of the chassis 2. The multiple connecting blocks 10 are evenly arranged around the chassis 2, and the multiple connecting blocks 10 are located on the side of the chassis 2 near the bottom. Bolts are installed through each of the multiple connecting blocks 10, and threaded holes are opened on the base 1 corresponding to the bolts on the multiple connecting blocks 10. When the base 1 is inserted into the sealing groove 8, the connecting blocks 10 abut against the top surface of the base 1 and correspond to the threaded holes. Then, the chassis 2 and the base 1 are fixedly installed by bolts threaded into the threaded holes.
[0038] Specifically, the water spray assembly 3 includes a high-pressure water pump 31, an inlet pipe 32, and high-pressure nozzles 33. The high-pressure water pump 31 is located inside the receiving cavity 7 and on one side of the walking drive device 6; the high-pressure water pump 31 is connected to an external water source and power supply. One end of the inlet pipe 32 is fixedly connected to the outlet end of the high-pressure water pump 31, and the end of the inlet pipe 32 away from the high-pressure water pump 31 is installed through the side wall of the receiving cavity 7 and located outside the casing 2. Multiple water spray branch pipes 321 are provided at the end of the inlet pipe 32 located outside the casing 2, and the multiple water spray branch pipes 321 are arranged vertically around the periphery of the inlet pipe 32 at intervals. There are multiple high-pressure nozzles 33, and the multiple high-pressure nozzles 33 are respectively fixedly installed at the ends of the multiple water spray branch pipes 321 away from the inlet pipe 32.
[0039] The cleaning component 4 includes a drive motor 41, a transmission shaft 42, and a mounting sleeve 43. The drive motor 41 is located inside the receiving cavity 7, on the side of the walking drive device 6 away from the high-pressure water pump 31. The drive motor 41 is fixedly mounted on the side wall inside the receiving cavity 7 and is connected to an external power source. A through hole is provided on the side wall of the receiving cavity 7, and a transmission bearing 11 is fixedly installed in the through hole. The transmission shaft 42 is rotatably mounted in the transmission bearing 11. The shaft of the drive motor 41 is fixedly connected to one end of the transmission shaft 42. The end of the transmission shaft 42 passing through the transmission bearing 11 is located outside the housing 2. The mounting sleeve 43 is fixedly mounted on the end of the rotating bearing away from the drive motor 41. Multiple connecting rods 12 are fixedly mounted on the mounting sleeve 43, and the multiple connecting rods 12 are arranged vertically around the circumference of the mounting sleeve 43 at intervals. A wire cleaning brush is fixedly mounted on the end of each of the multiple connecting rods 12 away from the mounting sleeve 43. An adjustment component 13 for adjusting the length of the connecting rod 12 is provided.
[0040] Reference Figure 3 and Figure 4 Furthermore, the connecting support rod 12 includes a main rod 121, an auxiliary rod 122, and an adjusting rod 123, all of which are rectangular tubing. The far end of the auxiliary rod 122 is fixedly connected to the mounting sleeve 43. The main rod 121 and the auxiliary rod 122 have the same diameter and are not interlocked. The main rod 121 is located at the end of the auxiliary rod 122 furthest from the mounting sleeve 43. The adjusting rod 123 is located between the main rod 121 and the auxiliary rod 122, with one end embedded in the auxiliary rod 122 and fixedly connected to it. The end of the adjusting rod 12 furthest from the auxiliary rod 122 is embedded in the main rod 121 and slidably installed within it.
[0041] Reference Figure 5 The adjusting assembly 13 includes a limiting plate 131 and a base plate 132. The base plate 132 is fixedly mounted on the side wall of the main rod 121. A pin 1311 passes through the limiting plate 131, and the limiting plate 131 is hinged to the base plate 132 via the pin 1311. A torsion spring 1312 is sleeved on the pin 1311. A horizontal plate 1313 is provided at one end of the limiting plate 131. A square hole 1211 for inserting the horizontal plate 1313 is provided on the main rod 121. Multiple fixing holes 1231 are provided along the length direction on the side wall of the adjusting rod 123 near the square hole 1211. The fixing holes 1231 are spaced apart along the length direction of the adjusting rod 123. In a natural state without external interference, the torsion spring 1312 continuously applies torque to the limiting plate 131 by virtue of the restoring force generated by its own elastic deformation. The torque drives the limiting plate 131 to rotate around the pin 1311, so that the horizontal plate 1313 at one end of the limiting plate 131 falls precisely into the square hole 1211 of the main rod 121.
[0042] When adjusting the length of the connecting telescopic rod, the operator needs to manually apply an external force to the limiting plate 131 to overcome the restoring force of the torsion spring 1312, causing the limiting plate 131 to rotate around the pin 1311. This causes the horizontal plate 1313 to disengage from the fixing hole 1231 of the adjusting rod 123 and the square hole 1211 of the main rod 121, releasing the limitation on the adjusting rod 123. At this time, the adjusting rod 123 can slide freely within the main rod 121. According to the actual inner diameter of the pipe and the cleaning requirements, the adjusting rod 123 can be slid to a suitable position so that the wire cleaning brush can maintain the optimal contact distance with the inner wall of the pipe.
[0043] After adjustment, the external force applied to the limiting plate 131 is released. The torsion spring 1312, relying on the restoring force generated by its own elastic deformation, drives the limiting plate 131 to rotate in the opposite direction around the pin 1311, so that the horizontal plate 1313 falls back into the square hole 1211 of the main rod 121 and the fixing hole 1231 of the corresponding position of the adjusting rod 123, thus completing the relocking of the adjusting rod 123, thereby stabilizing the connecting support rod 12 at the adjusted length, ensuring that the wire cleaning brush can maintain a stable working state when cleaning the inner wall of the pipe, and effectively cleaning the pipe dirt.
[0044] The implementation principle of this embodiment is as follows: the device moves within the pipe via the traveling wheels 5 on the base 1, and the traveling drive device 6 provides power to the traveling wheels 5. When it is necessary to clean the inner wall of the pipe, the drive motor 41 starts, driving the mounting sleeve 43 to rotate via the transmission main shaft 42. The connecting support rod 12 and the wire cleaning brush on the mounting sleeve 43 rotate at high speed to mechanically clean the inner wall of the pipe. Before cleaning pipes of different diameters, the operator can manually adjust the length of the connecting support rod 12 according to the inner diameter of the pipe. Specifically, an external force is applied to the limiting plate 131 to overcome the restoring force of the torsion spring 1312, causing the horizontal plate 1313 to disengage from the fixing hole 1231 of the adjusting rod 123 and the square hole 1211 of the main rod 121. Then, the main rod 121 is slid to adjust the position of the adjusting rod 123 within the main rod 121 until the wire cleaning brush can maintain a suitable contact distance with the inner wall of the pipe. After adjustment, the external force is released, and the torsion spring 1312 drives the limit plate 131 to rotate, causing the horizontal plate 1313 to re-insert into the corresponding fixing hole 1231 and square hole 1211, locking the length of the connecting support rod 12. Simultaneously, the high-pressure water pump 31 starts, pressurizing the external water source and delivering it through the inlet pipe 32 to the spray branch pipe 321 and high-pressure nozzle 33, spraying high-pressure water onto the inner wall of the pipe. The high-pressure water is evenly sprayed onto various parts of the inner wall of the pipe, rinsing and softening the dirt. Combined with the mechanical cleaning of the wire cleaning brush, this improves cleaning efficiency and effectiveness. The high-pressure water also provides cooling and lubrication, reducing friction between the wire cleaning brush and the inner wall of the pipe, extending the device's service life. The casing 2 and base 1 are sealed together by the sealing groove 8 and sealing gasket 9, preventing leakage of liquid or dust from the receiving cavity 7 and protecting internal components. The entire device requires no pipe excavation; through the adjustable connecting support rod 12 and the water spray assembly 3, it achieves efficient cleaning of the inner walls of pipes of different diameters.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
