The advantage of the utility model is that the municipal pipeline dredging device can adjust the dredging position, so that it is practical, and the dredging rod is driven to move forward and backward by the first electric push rod, so that the dredging is more convenient, and then the second motor is started, and the output shaft of the second motor rotates to drive the dredging rod to rotate. After the dredging is completed, the garbage inside the municipal pipeline is loose, and then the two second electric push rods are started, and the output shafts of the two second electric push rods are telescopic to drive the collection frame to move, and then when the collection frames are close to each other, the dredged garbage is clamped, making it convenient to clean, solving the problem that manual dredging is inconvenient and it is inconvenient to clamp the garbage inside the pipeline.

[0033] Specifically, when it is necessary to dredge the municipal pipeline, the device is installed at one end of the pipeline, and the walking unit 10 is controlled to start by an external controller, so that the mobile frame 1 moves in the pipeline, and cooperates with the existing remote probe to watch the situation in the pipeline in real time. When the mobile frame 1 moves to the position that needs to be dredged, the walking unit 10 stops working and observes the situation in the pipeline, selects a position that is easier to clamp for operation, and adjusts the position of the clamping unit 9. The horizontal position of the first movable seat 4 is adjusted by starting the first drive unit 5, the height position of the movable beam 2 is adjusted by starting the third drive unit 11, and the horizontal position of the clamping unit 9 along the pipeline direction is adjusted by starting the second drive unit 7. The clamping unit 9 is inserted into the obstruction in the pipeline, and the local obstruction is clamped by the clamping unit 9. The clamping unit 9 is driven to move backward again by starting the second drive unit 7 to remove the local obstruction. The above steps are repeated until the pipeline is dredged. Through the mobile frame 1 that can walk, the mobile frame 1 can move in the pipeline, which is suitable for dredging municipal pipelines at different installation positions, thereby improving the scope of application of the dredging device.

[0034] As a technical optimization scheme of the present invention, the first drive unit 5 includes a first drive motor 12 fixedly installed at one end of the moving beam 2, and a limit groove 19 adapted to the two ends of the moving beam 2 is opened through the relative side wall of the moving cavity 3 and penetrates the moving frame 1, and a sliding groove 13 adapted to the first moving seat 4 is opened through the relative side of the moving beam 2. A first screw rod 14 with one end fixedly connected to the output end of the first drive motor 12 is rotatably connected in the sliding groove 13, and the first screw rod 14 penetrates the first moving seat 4 and is threadedly connected thereto.

[0035] Specifically, when the first movable seat 4 needs to be moved along the length direction of the movable beam 2, the first drive motor 12 is started, and the output end of the first drive motor 12 drives the first screw rod 14 to rotate. When the first screw rod 14 rotates, it drives the first movable seat 4 to slide in the sliding groove 13, and then drives the first movable seat 4 to move along the sliding groove 13.

[0036] As a technical optimization solution of the present invention, the second drive unit 7 includes a mounting plate 15 fixedly mounted on the end of the moving rod 6 away from the clamping seat 8, and a second drive motor 16 is fixedly mounted on the mounting plate 15. The output end of the second drive motor 16 passes through the mounting plate 15 and the end is fixedly connected to a second screw rod 17. The second screw rod 17 passes through the first moving seat 4 and is threadedly connected thereto. A through opening 18 matching the moving rod 6 is opened through the opposite side of the first moving seat 4.

[0037] Specifically, when the moving rod 6 needs to be moved along the pipeline conveying direction, the second drive motor 16 is started, and the output end of the second drive motor 16 drives the second screw rod 17 to rotate. The second screw rod 17 is threadedly connected to the first moving seat 4, and the cross-section of the moving rod 6 and the through-hole 18 are adaptive rectangular shapes. Therefore, when the second screw rod 17 rotates, the moving rod 6 will move in the through-hole 18, and then drive the moving rod 6 to move along the pipeline conveying direction. At the same time, the number of second drive motors 16 is two, which increases the power when moving the moving rod 6 and increases the power when clearing the pipeline.

[0038] As a technical optimization solution of the present invention, the clamping unit 9 includes a third drive motor 20 fixedly mounted on one end of the clamping seat 8, a slide groove 21 is provided on the side of the clamping seat 8 away from the moving rod 6, two symmetrical second moving seats 22 are slidably connected in the slide groove 21, and a third screw rod 24 with one end fixedly connected to the output end of the third drive motor 20 is rotatably connected in the slide groove 21. When the third screw rod 24 rotates, it drives the two second moving seats 22 to move toward or away from each other, and a clamping plate 23 is fixedly connected to one side of the second moving seat 22.

[0039] Specifically, when the moving rod 6 drives the two clamping plates 23 to insert into the gap of the pipe blockage, the third drive motor 20 is started, and the output end of the third drive motor 20 drives the third screw rod 24 to rotate. The third screw rod 24 is a bidirectional screw rod with symmetrical side threads and opposite openings. When the third screw rod 24 rotates, it will drive the two second moving seats 22 to move toward or away from each other in the slide groove 21, thereby driving the two clamping plates 23 to clamp the blockage, and cooperate with the moving rod 6 moving back to pull out the blockage.

[0040] As a technical optimization solution of the present invention, the walking unit 10 includes a U-shaped fixed frame 25 provided on multiple sides of the mobile frame body 1, a mobile wheel 26 is rotatably connected in the fixed frame 25, and a fourth drive motor 27 for driving the mobile wheel 26 to rotate is fixedly installed on one side of the fixed frame 25.

[0041] Specifically, the side of each moving wheel 26 is in close contact with the inner wall of the pipeline. When the moving frame 1 needs to be driven to move in the pipeline, the fourth drive motor 27 is started, and the output end of the fourth drive motor 27 drives the moving wheel 26 to rotate, thereby achieving the effect of the moving frame 1 moving in the pipeline.

[0042] As a technical optimization scheme of the present invention, the third drive unit 11 includes a fifth drive motor 28 arranged on the side surfaces at both ends of the moving beam 2, and the side surfaces at both ends of the moving beam 2 are provided with installation cavities 29 for installing the fifth drive motor 28.

[0043] Specifically, when the height position of the movable beam 2 needs to be adjusted, the fifth drive motor 28 is started, and the output end of the fifth drive motor 28 drives the gear 30 to rotate, and the gear 30 engages with the tooth groove 32 in the connecting groove 31. Therefore, when the gear 30 rotates, it drives the fifth drive motor 28 to move. The fifth drive motor 28 is fixedly installed in the installation cavity 29, so the movable beam 2 moves up and down in the movable cavity 3 and the limit groove 19, thereby adjusting the height position of the movable beam 2.

[0044] As a technical optimization solution of the present invention, a collection frame 33 is provided on one side of the mobile frame 1, and a connecting frame 34 is fixedly installed on one side of the collection frame 33. The connecting frame 34 is fixedly installed on one side of the mobile frame 1 through fasteners.

[0045] Specifically, when the mobile frame 1 penetrates deeper into the pipeline, the cleaned blockage can be placed in the collection frame 33 and taken out of the pipeline. The collection frame 33 is fixedly installed on one side of the mobile frame 1 through the cooperation of fasteners and the connecting frame 34.

[0046] As a technical optimization solution of the present invention, telescopic devices 36 are fixedly installed on multiple side surfaces of the movable frame 1, and the fixed frame 25 is fixedly installed on the telescopic end of the telescopic device 36.
