[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] A magnetically driven, rolling municipal pipeline dredging device, such as Figure 1 and Figure 3 As shown, a magnetic ring 2 is installed inside the pipe to drive the device to move. Above the magnetic ring 2 and above the ground, a guide device 1 is installed to drive the magnetic ring 2 to move. The guide device 1 is electromagnetically connected to the magnetic ring 2. A socket is fixedly installed on one side of the first shielding plate 13. The socket is electrically connected to the storage battery 14. A cover plate 22 is hinged to one side of the socket.

[0028] The magnetic ring 2 is pulled or pushed to move by the magnetic force between the guide device 1 and the magnetic ring 2. It is worth noting that the guide device 1 has been disclosed in a magnetic control underground pipeline dredging or renovation construction device (CN202020634734.6). The specific implementation method will not be described in detail here. Under the action of magnetic force, the magnetic ring 2 can only move along the inner wall of the pipeline and cannot rotate. Open the cover plate 22 and the connection socket can charge the storage battery 14.

[0029] A magnetically driven, rolling municipal pipeline dredging device, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the unblocking structure is located on one side of the magnetic ring 2. The unblocking structure includes expandable and contractible metal strips 3. One side of each metal strip 3 has a crushing blade 6 for breaking up blockages. The unblocking structure also includes an end block 4 and a connecting rod 5. Several metal strips 3 are arranged on the wall of the connecting rod 5. One end of each metal strip 3 is fixedly connected to one side of the connecting rod 5, and the other end of each metal strip 3 is fixedly connected to one side of the end block 4. A telescopic rod is fixed between the end block 4 and the connecting rod 5. The unblocking structure also includes a star gear 16, a ring 19, and teeth 20. A second baffle plate 17 is fixedly installed inside the magnetic ring 2. A star gear 16 is located in the middle of the second baffle plate 17. Three star gears 16 surround the wheel 16, and the three star gears 16 mesh with the central star gear 16. A ring of teeth 20 is fixed on the wall of the magnetic ring 2, and the three star gears 16 mesh with the teeth 20. Each star gear 16 is rotatably connected to the second shielding plate 17. One end of the connecting rod 5 passes through the ring 19 and is fixedly connected to the central star gear 16. The connecting rod 5 is fixedly connected to the ring 19. A third shielding ring 18 is provided on the outer wall of the ring 19. The outer wall of the third shielding ring 18 is fixedly connected to the inner wall of the magnetic ring 2. Each of the three star gears 16 is fixedly connected to one end of a crushing blade 6. The three crushing blades 6 are disposed in the gap between the third shielding ring 18 and the ring 19.

[0030] When the central star gear 16 rotates, it drives the other three star gears 16 to rotate. The three star gears 16 drive the three crushing blades 6 to rotate while revolving around the teeth 20. The central star gear 16 drives the connecting rod 5, the ring 19, and the end block 4 to rotate. When the end block 4 encounters the blockage, it is pushed backward and compresses the connecting rod 5. The telescopic rod is also compressed. The connecting rod 5 is a flexible metal. When all the connecting rods 5 are compressed, their diameter increases. Each connecting rod 5 rotates forward continuously, penetrating into the blockage and rolling long plastic debris to the outside of the connecting rod 5. The three crushing blades 6 cooperate with the connecting rod 5, rotating forward continuously and moving in a circular motion to crush other blockages. After the end block 4 passes through the blockage, there is no resistance. The connecting rod 5 returns to its contracted state. Finally, when the device moves out of the pipe, it carries out the long plastic debris. This effectively prevents the crushing blades 6 from getting entangled when cleaning blockages.

[0031] A magnetically driven, rolling municipal pipeline dredging device, such as Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the unblocking structure also includes a traction rope 8, a transmission rod 12, a first baffle plate 13, a battery 14, a motor 15, and a spur gear 21. One end of the transmission rod 12 passes through the second baffle plate 17 and a spur gear 21 and is fixedly connected to one side of the central star gear 16. The transmission rod 12 is rotatably connected to the second baffle plate 17 and is fixedly connected to the spur gear 21. Another spur gear 21 is provided on one side of the spur gear 21, and the two spur gears 21 mesh with each other. A motor 15 is provided on one side of the other spur gear 21, and the rotating shaft of the motor 15 is fixedly connected to one side of the spur gear 21. A battery 14 is provided on one side of the motor 15. The battery 14 and the motor 15 are fixedly mounted on one side of the first baffle plate 13. The first baffle plate 13 is fixedly mounted on the inner wall of the magnetic ring 2. One end of the transmission rod 12 passes through the first baffle plate 13 and is rotatably connected to the first baffle plate 13. The end of the transmission rod 12 is fixedly connected to one end of the traction rope 8.

[0032] The battery 14 is electrically connected to the motor 15. Before entering the pipeline, the power of the motor 15 is turned on. The motor 15 drives one spur gear 21 to rotate, and one spur gear 21 drives another spur gear 21 to rotate. The transmission rod 12 rotates accordingly, and the transmission rod 12 drives the central planetary gear 16 to rotate. The traction rope rotates, and the other end of the traction rope is set outside the pipeline to prevent device failure. The traction rope is used to pull the device out of the pipeline.

[0033] A magnetically driven, rolling municipal pipeline dredging device, such as Figure 1 , Figure 3 and Figure 7 As shown, the other side of the magnetic ring 2 is provided with an elastic brush head 7 that rolls to clean the inner wall of the pipe and is linked with the crushing blade 6. The unblocking structure also includes a rotating rod 10 and a spring rod 11. Several rotating rods 10 are fixedly installed on the wall of the transmission rod 12. The other end of each rotating rod 10 is fixedly connected to a spring rod 11. The upper end of the spring rod 11 extends into the cavity of the lower end. A spring is fixed between the bottom of the upper end and the bottom surface of the cavity of the lower end. The upper end and the lower end are slidably connected. The unblocking structure also includes a U-shaped block 9. The upper end of each spring rod 11 is fixedly connected to one side of a U-shaped block 9. An elastic brush head 7 is provided in the middle of each U-shaped block 9. The two ends of each elastic brush head 7 are rotatably connected to the two sides of the U-shaped block 9. Several bristles are provided on the wall of each elastic brush head 7 and the elastic brush head 7 is in close contact with the pipe wall.

[0034] The rotation of the transmission rod 12 drives the rotating rod 10 and the spring rod 11 to rotate, and the elastic brush head 7 rotates accordingly. The bristles clean the inner wall of the pipe. The spring rod 11 drives the elastic brush head 7 to retract according to the unevenness of the pipe wall, so that the bristles always stick to the inner wall of the pipe. The brush head 7 is arranged in a cross shape with the pipe. When the magnetic ring 2 moves, it drives the entire device to move together. The brush head 7 rolls and moves in a circle along the inner wall of the pipe, resulting in high cleaning efficiency.

[0035] The working principle of this utility model is as follows: the magnetic force between the guide device 1 and the magnetic ring 2 pulls or pushes the magnetic ring 2 to move. It is worth noting that the guide device (1) has been disclosed in a magnetic control underground pipeline dredging or renovation construction device (CN202020634734.6), and the specific implementation method will not be described in detail here. Under the action of magnetic force, the magnetic ring 2 can only move along the inner wall of the pipeline and cannot rotate. When the cover plate 22 is opened, the connection socket can charge the storage battery 14. When the central planetary gear 16 rotates, it drives another Three star gears 16 rotate, driving three crushing blades 6 to rotate around the teeth 20. The central star gear 16 drives the connecting rod 5, the ring 19, and the end block 4 to rotate. When the end block 4 encounters the blockage, it is pushed backward to compress the connecting rod 5, and the telescopic rod is also compressed. The connecting rod 5 is a flexible metal. As all the connecting rods 5 are compressed, their diameter increases. Each connecting rod 5 rotates forward continuously, penetrating into the blockage and rolling long plastic waste to the outside of the connecting rod 5. The three crushing blades 6 cooperate with the connecting rod 5. The device continuously rotates forward in a circular motion, breaking up other blockages. After the end block 4 passes through the blockage, there is no resistance, and the connecting rod 5 retracts. Finally, when the device moves out of the pipe, it carries away long pieces of plastic waste. This effectively prevents the breaking blades 6 from getting tangled when cleaning blockages. The battery 14 is electrically connected to the motor 15. Before entering the pipe, the motor 15 is powered on. The motor 15 drives one spur gear 21 to rotate, and one spur gear 21 drives another spur gear 21 to rotate. The transmission rod 12 rotates accordingly, driving the central planetary gear 16 to rotate. The guide rope rotates, with the other end of the traction rope positioned outside the pipe to prevent device malfunction. The traction rope pulls the device out of the pipe. The transmission rod 12 rotates, causing the rotating rod 10 and the spring rod 11 to rotate. The elastic brush head 7 rotates accordingly, and the bristles clean the inner wall of the pipe. The spring rod 11 retracts the elastic brush head 7 according to the unevenness of the pipe wall, ensuring that the bristles always adhere to the inner wall of the pipe.
