Abstract
Description
Technical Field
[0001] This invention belongs to the field of pipeline dredging technology, specifically referring to a dredging device suitable for complex pipeline environments. Background Technology
[0002] In municipal drainage, industrial circulating water, and chemical fluid transportation, pipeline networks are the core infrastructure ensuring the normal flow of fluids. However, during long-term operation, pipeline networks are prone to blockages due to sediment deposition, oil adhesion, and debris accumulation. This not only significantly reduces fluid flow efficiency but can also lead to serious malfunctions such as corrosion of the pipeline walls, sudden increases in local pressure, and even pipeline rupture, disrupting normal production and daily life. Especially in complex pipeline environments, dredging operations face numerous technical challenges, and existing dredging equipment is insufficient to meet practical needs, mainly exhibiting the following deficiencies: 1. Most existing dredging devices are designed with a fixed structure and can only be adapted to straight pipe sections with a single diameter. When facing pipe networks with varying pipe diameters, it is necessary to stop the machine and replace dredging components of different specifications, which is cumbersome and inefficient. 2. The cleaning components of traditional dredging devices (such as fixed scrapers and rigid brushes) are mostly designed with fixed angles or rotation radii, which can easily create cleaning blind spots in uneven areas of the inner wall of the pipeline, leading to siltation and residue.
[0003] In summary, the industry urgently needs a dredging device that can adapt to complex pipe network configurations, provide uniform cleaning results, facilitate connection and maintenance, and ensure stable operation, in order to address the many pain points of existing technologies in complex pipe network environments and improve the efficiency of dredging operations and the effectiveness of pipe network protection. Summary of the Invention
[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a dredging device suitable for complex pipeline network environments, which effectively solves the problems currently on the market.
[0005] The technical solution adopted by this invention is as follows: This invention proposes a dredging device suitable for complex pipe network environments, including a device housing, a protective shell on the outer surface of the device housing, a drive motor installed inside the protective shell, a rotating disk connected to the output end of the drive motor, a sliding groove on the rotating disk, a cleaning block inside the sliding groove, a telescopic spring connecting the cleaning block and the rotating disk, a fixed disk inside the device housing, a straight groove on the fixed disk, a rotating disk connected to the fixed disk, an inclined groove on the rotating disk, a movable rod inside the inclined groove and the straight groove, a support block installed on the movable rod, and rollers on the outer surface of the support block.
[0006] Furthermore, a connecting base is installed on the outer shell of the device, a docking block is provided inside the connecting base, a locking block is provided on the docking block, a rotation control rod is installed on the docking block, a transmission connecting rod is connected between one end of the rotation control rod and the locking block, a positioning pin is connected between the rotation control rod and the docking block, and a docking flange is provided on the outer surface of the docking block.
[0007] Furthermore, the protective housing is detachably connected to the outer surface of the device housing, the drive motor is detachably connected to the device housing, the rotating disk is fixedly connected to the output end of the drive motor, and the sliding grooves are evenly distributed on the rotating disk.
[0008] Furthermore, the cleaning block is slidably connected within the sliding groove, one end of the telescopic spring is fixedly connected to the sliding groove, and the other end of the telescopic spring is fixedly connected to the cleaning block.
[0009] Furthermore, the fixed disk is fixedly connected to the inner surface of the device housing, the straight grooves are evenly opened on the fixed disk, the rotating disk is rotatably connected to the fixed disk, the inclined grooves are evenly distributed on the rotating disk, and the positions of the inclined grooves correspond to the positions of the straight grooves.
[0010] Furthermore, the movable rod is slidably connected in a straight groove, the movable rod is slidably connected in an inclined groove, the support block is fixedly connected to the movable rod, and the roller is detachably mounted on the outer surface of the support block.
[0011] Furthermore, the limiting block is symmetrically arranged on the device housing, the limiting block is arc-shaped, the fastening bolt passes through and is threadedly connected to the limiting block, and the fastening bolt is threadedly connected to the device housing.
[0012] Furthermore, the connecting base is fixed to the outer shell of the connecting device, the docking block is slidably connected to the connecting base, and the locking blocks are evenly distributed on the docking blocks, and the locking blocks are slidably connected to the docking blocks.
[0013] Furthermore, the rotation control rod is rotatably connected to the docking block, one end of the transmission link is rotatably connected to the locking block, and the other end of the transmission link is rotatably connected to the rotation control rod.
[0014] Furthermore, the positioning pin passes through and slides through the transmission connecting rod, the positioning pin is detachably connected to the docking block, and the docking flange is fixedly connected to the outer surface of the docking block.
[0015] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The support adjustment component adopts a pure mechanical linkage structure. Through the design of "rotating disk → inclined groove driving movable rod → support block and roller radial movement", the support radius of the roller can be flexibly adjusted: the operator only needs to rotate the rotating disk, and the inclined groove side wall can push the movable rod to slide smoothly along the straight groove of the fixed disk, driving the roller to approach or move away from the center of the device, and quickly adapt to the pipe network with different pipe diameters; and the arc-shaped limit block set in the center can further lock the position of the support block by tightening bolts, so as to prevent the support structure from shifting when the device travels in the variable diameter section and curve, ensuring the stability of travel, without relying on hydraulic or electric components, with strong resistance to sewage and silt erosion and low failure risk; (2) The cleaning component achieves adaptive adjustment of cleaning force through the elastic combination design of "telescopic spring + cleaning block": when the drive motor drives the rotating disk to rotate, the cleaning block extends outward under the action of centrifugal force and makes close contact with the inner wall of the pipe network; when it encounters the raised area of the inner wall of the pipe network, the telescopic spring is compressed and the cleaning block automatically retracts to reduce the contact pressure and avoid scratching the pipe network; when it encounters the concave area, the telescopic spring extends and pushes the cleaning block into the concave area to ensure that it fits the inner wall to remove the sludge and there are no blind spots in cleaning; at the same time, the cleaning block is slidably connected in the sliding groove and can be quickly replaced according to the wear condition. It is suitable for different types of sludge such as mud and oil stains, and the cleaning effect and pipe network protection are taken into account, with a wide range of applications.

A rotation control rod 20 is installed on the docking block 18. A transmission connecting rod 21 is connected between one end of the rotation control rod 20 and the locking block 19. A positioning pin 22 is connected between the rotation control rod 20 and the docking block 18. A docking flange 23 is provided on the outer surface of the docking block 18.
[0023] The protective housing 2 is detachably connected to the outer surface of the device housing 1, the drive motor 3 is detachably connected to the device housing 1, the rotating disk 4 is fixedly connected to the output end of the drive motor 3, and the sliding grooves 5 are evenly opened on the rotating disk 4.
[0024] The cleaning block 6 is slidably connected to the sliding groove 5. One end of the telescopic spring 7 is fixedly connected to the sliding groove 5, and the other end of the telescopic spring 7 is fixedly connected to the cleaning block 6.
[0025] The fixed disk 8 is fixedly connected to the inner surface of the device housing 1. Straight grooves 9 are evenly opened on the fixed disk 8. The rotating disk 10 is rotatably connected to the fixed disk 8. Inclined grooves 11 are evenly distributed on the rotating disk 10, and the positions of the inclined grooves 11 correspond to the positions of the straight grooves 9.
[0026] The movable rod 12 is slidably connected to the straight groove 9 and the inclined groove 11. The support block 13 is fixedly connected to the movable rod 12, and the roller 14 is detachably installed on the outer surface of the support block 13.
[0027] The limiting block 15 is centrally symmetrically arranged on the device housing 1. The limiting block 15 is arc-shaped. The fastening bolt 16 passes through and is threadedly connected to the limiting block 15. The fastening bolt 16 is threadedly connected to the device housing 1.
[0028] The connecting base 17 is fixed to the outer shell 1 of the connecting device, the docking block 18 is slidably connected to the connecting base 17, and the locking blocks 19 are evenly distributed on the docking block 18, and the locking blocks 19 are slidably connected to the docking block 18.

[0031] In practical use, first adjust the support adjustment components according to the pipe diameter of the pipeline to be dredged: open the outer shell 1 of the device and rotate the rotating disk 10. Its inclined groove 11 pushes the movable rod 12 to slide radially along the straight groove 9 of the fixed disk 8, driving the support block 13 and the roller 14 to move to the support position that matches the pipe diameter; then tighten the fastening bolts 16 on the limit block 15 to fix the position of the support block 13 and ensure that the roller 14 fits against the inner wall of the pipeline; install the protective shell 2 on the outer surface of the outer shell 1 of the device to protect the internal drive motor 3, and complete the device assembly and pipeline adaptation.
[0032] The rotation control rod 20 of the rotating connection assembly pulls the locking block 19 into the docking block 18 through the transmission link 21; the docking block 18 is inserted into the connecting base 17 on the outer shell 1 of the device, and the rotation control rod 20 is rotated in the opposite direction. The locking block 19 pops out under the thrust of the rotation control rod 20 and engages with the slot of the connecting base 17, thus fixing the docking block 18 to the connecting base 17.

[0033] Start the drive motor 3. The output of the drive motor 3 drives the rotating disk 4 to rotate. The cleaning block 6 on the rotating disk 4 extends outward along the sliding groove 5 under the action of centrifugal force and contacts the inner wall of the pipe network. The cleaning block 6 scrapes the inner wall of the pipe network during rotation to remove the sludge. The telescopic spring 7 adaptively adjusts the extension length and contact pressure of the cleaning block 6 according to the concave and convex shape of the inner wall of the pipe network to ensure that it fits the inner wall without damaging the pipe network. At the same time, the traction device drives the device to move along the pipe network, and the roller 14 rolls along the inner wall of the pipe network, supporting the stable advancement of the device.
[0034] After the dredging operation is completed, turn off the drive motor 3 and disconnect the traction equipment from the docking flange 23; rotate the control lever 20 to retract the locking block 19 and remove the docking block 18; if maintenance is required, disassemble the protective shell 2, check the operating status of the drive motor 3, and if necessary, disassemble and replace the drive motor 3; if the roller 14 is worn, disassemble the old roller and replace it with a new roller; if the cleaning block 6 is worn, replace the cleaning block 6 directly. After completing the maintenance, the next dredging operation can begin. The above is the overall workflow of this invention. Repeat this step the next time it is used. The actual operation process is very simple and easy to implement.
