[0032] As Figures 1 to 5 shown: A pipeline dredging device includes:

[0033] The main body 1, and the main body 1 is a frame structure;

[0034] The circular walking components 2, and there are several groups of circular walking components 2, which are respectively arranged on the outer diameter of the main body 1. The several groups of circular walking components 2 are centrosymmetric. The circular walking components 2 are attached to the inner wall of the pipeline and walk along the pipeline;

[0035] The dredging component 3, and the dredging component 3 is arranged on the inner diameter of the main body 1 and includes a telescopic end 31. A dredging block 311 is arranged at the end of the telescopic end 31. The telescopic end 31 drives the dredging block 311 to perform reciprocating motion to dredge the pipeline.

[0036] The main body 1 adopts a frame structure, which can provide support and fixation for the device, while reducing the amount of material used and lightening the weight of the equipment. The annular walking assembly 2 consists of several groups, which are arranged around the outer diameter of the main body 1 and are centrally symmetrically arranged. Each group of walking assemblies fits the inner wall of the pipeline, enabling the device to walk stably in the pipeline. The fitting design of the annular walking assembly 2 and the inner wall of the pipeline ensures that the dredging device is not easily deflected or stuck in a complex pipeline structure, and can move forward, backward or remain stationary flexibly to locate the dredging area.

[0037] The dredging assembly 3 is located at the inner diameter of the main body 1 and has a telescopic end 31. A dredging block 311 is installed at the end of the telescopic end 31, which is responsible for the actual dredging operation. The reciprocating movement of the telescopic end 31 enables the dredging block 311 to contact and clean the blockages and sediments on the inner wall of the pipeline, such as silt, garbage, biological attachments, etc., thereby restoring the smoothness of the pipeline.

[0038] After the device is started, the annular walking assembly 2 fits the inner wall of the pipeline and pushes the main body 1 forward. When a blockage or sediment is detected, the telescopic end 31 of the dredging assembly 3 is activated, driving the dredging block 311 to perform a reciprocating movement to remove the blockage. In this way, the device can clean the pipeline section by section, continue to move forward after completing one dredging, and start the dredging assembly 3 again to clean when encountering a new blockage point, achieving the effect of continuous dredging. The walking and dredging functions reduce the frequency of moving the dredging device, improve the efficiency of pipeline dredging, and shorten the overall operation time.

[0039] In this embodiment, the annular walking assembly 2 includes:

[0040] A connecting rod 21, one end of which is rotatably connected to the main body 1;

[0041] A walking main body 22, which is rotatably connected to the other end of the connecting rod 21, and the walking main body 22 fits the inner wall of the pipeline;

[0042] A compression spring 23, one end of which is connected to the connecting rod 21 and the other end is connected to the walking main body 22. The compression spring 23 presses the walking main body 22 to fit the inner wall of the pipeline.

[0043] One end of the connecting rod 21 is rotatably connected to the device main body 1, enabling the walking assembly to flexibly adjust the angle within a certain range to adapt to the changes in different pipe diameters and pipe shapes, ensuring that the dredging device can move forward stably in the pipeline.

[0044] Through the elasticity of the compression spring 23, the walking body 22 can always closely adhere to the inner wall of the pipeline. Even if the pipeline diameter changes slightly or the inner wall surface is uneven, the compression spring 23 can automatically adjust the adhesion force of the walking body 22. The design of the compression spring 23 allows the walking body 22 to automatically adjust the adhesion force according to the changes in the inner wall of the pipeline, adapt to various pipeline diameters and inner wall conditions, and improve the applicability of the device. The walking body 22 always closely adheres to the inner wall of the pipeline during movement, can effectively resist the influence of external forces, and ensure the smooth and lasting movement of the dredging device.

[0045] Among them, the walking body 22 includes:

[0046] The walking track 221 is arranged around the walking body 22 and walks along the pipeline direction;

[0047] The driving mechanism is arranged inside the walking body 22 and drives the walking track 221 to walk.

[0048] The walking track 221 has stronger passability than traditional wheels, can adapt to the unevenness and corners inside the pipeline, and improves the traveling flexibility of the device inside the pipeline. The track structure provides a larger contact area, increases the friction force, enables the device to stably adhere to the inner wall of the pipeline, and avoids affecting the continuity of the dredging operation due to sliding or skidding. The walking track 221 can select different materials (such as rubber or anti-slip composite materials) according to the material and shape of the inner wall of the pipeline to enhance the adhesion and adapt to various complex inner wall conditions of the pipeline.

[0049] The driving mechanism can adopt electric drive or hydraulic drive, and adjust the driving mode according to the application requirements to provide sufficient power support. The electric drive mode is suitable for small and lightweight dredging devices, while the hydraulic drive is suitable for higher power and long-term working scenarios.

[0050] As a preference of the above embodiment, the annular walking assembly 2 is set to 3 groups, and the 3 groups of annular walking assemblies 2 are centrosymmetric. The centrosymmetric design of the three groups of annular walking assemblies 2 enables the device to balance the forces in all directions when walking in the pipeline, and improves the stability and adaptability of the device during the movement in the pipeline.

[0051] Each group of the annular walking assembly 2 has at least two connecting rods 21, and the two connecting rods 21 are arranged in parallel. Each group of the annular walking assembly 2 has at least two connecting rods 21, and the two connecting rods 21 are arranged in parallel. This design provides a more solid and stable support structure for the walking body 22. The parallel design of the double connecting rods 21 not only enhances the structural strength of the annular walking assembly 2, but also can effectively disperse the pressure and prevent the deformation or damage of a single connecting rod 21 under complex pipeline conditions.

[0052] Among them, the connecting rod 21 is arranged crosswise to the length extension direction of the compression spring 23.

[0053] The crosswise arrangement enables the compression spring 23 to provide more stable elastic force, maintaining the smooth operation of the walking body 22 inside the pipeline and keeping it closely attached to the inner wall even when the pipeline is irregular. The crosswise structure has a certain buffering effect. When the device encounters external force or impact while walking inside the pipeline, the cross angle between the compression spring 23 and the connecting rod 21 can absorb part of the impact force and reduce the direct impact on the walking body 22.

[0054] In this embodiment, a plurality of protrusions 2211 are provided on the walking track 221, and the protrusions 2211 are made of flexible material.

[0055] A plurality of protrusions 2211 are provided on the walking track 221, and the protrusions 2211 are made of flexible material (such as rubber or silica gel). These flexible protrusions 2211 can effectively increase the friction between the track and the inner wall of the pipeline, preventing the device from slipping inside the pipeline. The flexible protrusions 2211 have a certain buffering and adaptability when encountering the uneven inner wall of the pipeline, can fit the pipeline surface better, and at the same time reduce the damage to the inner wall of the pipeline.

[0056] As a preference of the above embodiment, the dredging component 3 includes a linear driving mechanism 32, and the telescopic end 31 is arranged on the linear driving mechanism 32. The dredging component 3 includes a linear driving mechanism 32 for precisely controlling the reciprocating motion of the telescopic end 31. The linear driving mechanism 32 can be an electric lead screw, a cylinder or a hydraulic cylinder, and different driving methods are selected according to requirements.

[0057] The telescopic end 31 is fixed on the linear driving mechanism 32. When the linear driving mechanism 32 is started, the telescopic end 31 drives the dredging block 311 to perform reciprocating motion along the axial direction of the pipeline. This design can ensure that the dredging block 311 performs cleaning with precise force and frequency when dredging the pipeline, achieving an efficient dredging effect. The precise control function of the linear driving mechanism 32 enables the dredging component 3 to adjust the dredging force according to different blockage degrees, avoiding poor effects or equipment damage caused by excessive or insufficient dredging force.
