Description

Technical Field

[0001] The utility model relates to a dredging device for drainage pipes, belonging to the technical field of drainage pipes. Background Technique

[0002] Drainage pipes are mainly responsible for operations such as rainwater, sewage, and farmland irrigation and drainage. Since corrugated pipes effectively overcome the drawback that plane round-hole products are easily blocked and affect the drainage effect, they are widely used in drainage fields such as highway and railway subgrades, subway projects, and slope protection caused by high water content, as well as underground irrigation and drainage systems in horticulture according to different drainage requirements. After long-term use of drainage pipes, silt accumulates inside. If the silt is not removed in time, it is easy to affect the drainage efficiency. Currently, the silt in drainage pipes is regularly cleaned manually.

[0003] Chinese Patent No.: CN213653730U mentions a dredging device for drainage pipes. When in use, the user holds the handle to dredge the drainage pipe, so that the brush plate can extend into the inner side of the pipe for dredging. At this time, the telescopic rod can slide in the chute, and then the telescopic spring contracts, and can effectively buffer the acting force generated during brushing. However, this device only uses the brush plate to dredge the drainage pipe, and the effect is not good. Moreover, it is not convenient to dredge the inside of a long drainage pipe, and its practicability needs to be improved. Now, there is an urgent need for a dredging device for drainage pipes to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a dredging device for drainage pipes to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A dredging device for drainage pipes includes a cylindrical rod, a straight rack, a motor sleeve, and a conical dredging head. An arc-shaped shell is integrally arranged at the upper end of the cylindrical rod, and a straight gear is installed inside the arc-shaped shell. A rack chute is opened at the left end of the cylindrical rod, and a straight rack is slidably arranged inside the rack chute. The left end of the straight rack is fixedly connected to the motor sleeve. Three integral sleeves are equiangularly penetrated through the circumferential side of the motor sleeve. Electric push rods are installed inside all three integral sleeves. Bull's-eye universal balls are installed inside the movable ends of all three electric push rods. A waterproof motor is installed at the left end inside the motor sleeve. A motor shaft is arranged at the left end of the waterproof motor, and a conical dredging head is fixed at the left end of the motor shaft. A plurality of arc-shaped blades are fixedly arranged at equal angles on the conical surface of the conical dredging head.

[0006] Further, a lightweight handle is longitudinally fixed to the right end of the cylindrical rod.

[0007] Further, the straight rack is in meshing transmission with the spur gear. A small motor is installed at the front end of the arc-shaped shell, and the shaft end of the small motor is in transmission connection with the spur gear.

[0008] Further, a limit bolt is disposed through the left side of the lower end of the cylindrical rod, and the threaded end of the limit bolt abuts against the left side of the lower end of the straight rack.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a drainage pipeline dredging device, including a cylindrical rod 2, a straight rack 6, a motor sleeve 9 and a conical dredging head 15. An arc-shaped shell 3 is integrally arranged at the upper end of the cylindrical rod 2, and a straight gear 5 is installed inside the arc-shaped shell 3. A rack chute 7 is opened at the left end of the cylindrical rod 2, and a straight rack 6 is slidably arranged in the rack chute 7. The left end of the straight rack 6 is fixedly connected to the motor sleeve 9. Three integral sleeves 10 are equiangularly penetrated through the circumferential side of the motor sleeve 9. Electric push rods 11 are installed inside all three integral sleeves 10. Bull's-eye universal balls 12 are installed inside the movable ends of the three electric push rods 11. A waterproof motor 13 is installed at the left end inside the motor sleeve 9. A motor shaft 14 is arranged at the left end of the waterproof motor 13. A conical dredging head 15 is fixed to the left end of the motor shaft 14. A plurality of arc-shaped blades 16 are fixedly arranged at equal angles on the conical surface of the conical dredging head 15. This design solves the problems that the original device has poor dredging effect and is not convenient for dredging the inside of a longer drainage pipeline.

[0018] As the first embodiment of the present utility model: a lightweight handle 1 is longitudinally fixed to the right end of the cylindrical rod 2. By adding the lightweight handle 1, it is convenient for the staff to hold the device. The straight rack 6 and the straight gear 5 are in meshing transmission. A small motor 4 is installed at the front end of the arc-shaped shell 3, and the shaft end of the small motor 4 is in transmission connection with the straight gear 5. By adding the small motor 4, the straight gear 5 can be driven to rotate, so that the straight gear 5 can drive the straight rack 6 to move. A limit bolt 8 is penetrated through the left side of the lower end of the cylindrical rod 2, and the threaded end of the limit bolt 8 abuts against the left side of the lower end of the straight rack 6. By adding the limit bolt 8, the straight rack 6 can be prevented from sliding by itself in the rack chute 7. The edges of the plurality of arc-shaped blades 16 are all polished. By adding the plurality of arc-shaped blades 16, when the conical dredging head 15 rotates for dredging, larger sludge blocks can be broken.

[0019] As the second embodiment of the present utility model: When it is necessary to clean the silt inside the drainage pipe, move the conical dredging head 15, motor shaft 14, waterproof motor 13 and motor sleeve 9 into the drainage pipe. Then, start the three electric push rods 11 simultaneously. The movable ends of the three electric push rods 11 will drive the three bull's-eye universal balls 12 to move outwards until the rolling ends of the three bull's-eye universal balls 12 are in sliding contact with the inside of the drainage pipe. Then, hold the lightweight handle 1 and set the cylindrical rod 2 horizontally. Start the waterproof motor 13, and the shaft end of the waterproof motor 13 can drive the motor shaft 14, conical dredging head 15 and multiple arc-shaped blades 16 to rotate. Then, loosen the limit bolt 8 and start the small motor 4. The small motor 4 will drive the spur gear 5 to rotate, so that the straight rack 6 will move outwards in the rack chute 7. Further, the straight rack 6 will drive the motor sleeve 9, waterproof motor 13, motor shaft 14 and conical dredging head 15 to move towards the inside of the drainage pipe. During this process, the three bull's-eye universal balls 12 will slide on the inner wall of the drainage pipe until the rotating conical dredging head 15 and multiple arc-shaped blades 16 come into contact with the silt inside the drainage pipe, and then the silt at that place will be rotated and dispersed and dredged.
