At present, the most common dredging methods for drainage pipe networks are mechanical means such as pipe dredging vehicles and high-pressure flushing vehicles to dredge the drainage pipe networks. For example, the patent with the publication number CN214391496U discloses a peristaltic pipe dredging robot, which cleans the silt in the pipe by driving the reamer and the cleaning brush to rotate. However, such methods are only applicable to the cleaning of loose sludge and sediments in drainage pipe networks and cannot effectively clean the harder sediments that have settled in the drainage pipe networks for a long time, resulting in poor dredging effects.

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer toFigures 1 to 4 , the present utility model provides a technical solution: a sediment dredging device for a drainage pipe network, including a driving head 1. One side of the driving head 1 is fixed with a support shaft 8. One side of the driving head 1 is rotatably fitted with a reciprocating screw rod 9. A slider 10 is slidably fitted on the support shaft 8. The slider 10 corresponds to the reciprocating screw rod 9. A plurality of push rods 11 are installed on the circumferential side of the slider 10. A plurality of connecting rods 12 are installed at the end of the support shaft 8. The connecting rods 12 correspond to the push rods 11. One end of the connecting rod 12 is rotatably fitted with a digging head 13. A plurality of electric wheels 4 are installed on the circumferential side of the driving head 1.

[0022] In this embodiment, a chute 2 is opened in the driving head 1. A support rod 3 is slidably fitted in the chute 2. One end of the support rod 3 is fixedly connected to the electric wheel 4. A locking bolt is installed on one side of the driving head 1. The locking bolt corresponds to the support rod 3.

[0023] Specifically, when dredging, slide the support rod 3 so that the electric wheel 4 can contact the inner wall of the pipe. Then rotate the locking bolt to fix the position of the support rod 3, so as to fix the position of the electric wheel 4. Then place the driving head 1 in the drainage pipe network so that the electric wheel 4 contacts the inner wall of the pipe, and thus it can move in the pipe.

[0024] A motor 15 is fixed in the driving head 1. The output end of the motor 15 is fixedly connected to the reciprocating screw rod 9. The reciprocating screw rod 9 is in threaded cooperation with the slider 10. The push rod 11 is rotatably connected to the slider 10. The connecting rod 12 is rotatably connected to the support shaft 8. A connecting head 16 is installed between the push rod 11 and the connecting rod 12. The connecting head 16 is rotatably connected to the push rod 11. The connecting head 16 is slidably connected to the connecting rod 12. A limiting rod 14 is fixed on the digging head 13. A torsion spring is installed between the digging head 13 and the connecting rod 12.

[0025] Specifically, when the device is dredging, start the motor 15 to drive the reciprocating screw rod 9 to rotate, thereby driving the slider 10 to slide back and forth along the support shaft 8. The slider 10 pushes the push rod 11, so that the push rod 11 drives the connecting rod 12 to rotate, and thus the connecting rod 12 drives the digging head 13 to move. When the limiting rod 14 contacts the inner wall of the pipe, the limiting rod 14 will limit the digging head 13, so that the digging head 13 rotates, and the silt on the side can be dug, which is convenient for pumping silt.

[0026] Two clamps 5 are installed on the side of the driving head 1. A sludge suction pipe 6 and a flushing pipe 7 are respectively installed in the two clamps 5.

[0027] Specifically, when pumping silt, flush water through the flushing pipe 7, and then extract the sediment through the sludge suction pipe 6, which can ensure the pumping silt effect.

[0028] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
