Description

Technical Field

[0001] The utility model relates to the technical field of pipeline desilting devices, in particular to a desilting device for a sewage pipeline. Background Art

[0002] Pipeline desilting technology refers to the use of various methods and tools to remove silt, garbage and other obstructions in pipelines to ensure smooth operation of pipelines. Pipeline desilting technology is widely used in urban drainage systems, industrial pipelines and farmland irrigation systems.

[0003] After searching, a Chinese patent disclosed a method for dredging pipelines, and its authorization announcement number is (CN215211482U), which includes a supporting central axis, an adjustable connecting arm and a brush; the number of brushes is at least 2, and the brushes are arranged axially along the supporting central axis, and the cleaning bristles on the brushes face away from the supporting central axis; the supporting central axis is a hollow optical axis; one end of the adjustable connecting arm is connected to the supporting central axis, and the other end is connected to the brush, and the adjustable connecting arm is a connecting arm with adjustable length, and the radial distance between the brush and the supporting central axis is adjusted by adjusting the length of the connecting arm.

[0004] This patent arranges brushes circumferentially along the support center axis to adapt to the shape of the pipe, and the brushes are connected to the support center axis through an adjustable connecting arm, so that the relative distance between the brushes and the support center axis can be adjusted, that is, the same device can be applied to pipes with different diameters, saving equipment costs. In actual use, although this patent solves the problem of adjustable relative distance between support centers, it only scrapes off the silt on the inside of the sewage pipe during dredging work, and cannot discharge the silt from the pipe. This situation will affect the dredging effect of the sewage pipe. For this reason, we propose a dredging device for sewage pipes. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 5As shown, in this embodiment, a desilting device for a sewage pipe includes a function box 1, one side of the function box 1 is fixedly connected to a collecting box 2, one side of the function box 1 is rotatably connected to a connecting tube 5, one end of the connecting tube 5 is fixedly connected to a rotating disk 3, an arc-shaped scraper 4 is fixedly connected to the outer side of the rotating disk 3, a collecting hole 23 is opened in the middle of the rotating disk 3, and the collecting hole 23 is communicated with the inner wall of the connecting tube 5, a rotating assembly is arranged on the top of the function box 1, and the rotating assembly is used to drive the rotating disk 3 to rotate, a collecting tube 14 is arranged between the inner walls of the connecting tube 5, and one end of the collecting tube 14 It penetrates the function box 1 and extends to the interior of the collection box 2. An embedding groove 17 is provided on one side of the collection box 2. A sewage drawer 11 is slidably connected between the inner walls of the embedding groove 17. A self-locking component is provided on the outer side of the collection box 2. The self-locking component is used to lock the sewage drawer 11. A mounting block 15 is fixedly connected to the inside of the function box 1. A sludge pump 16 is fixedly installed on the top of the mounting block 15. The output end of the sludge pump 16 extends to the inside of the collection pipe 14. A cross plate 12 is fixedly connected to one side of the collection box 2. Four auxiliary rollers 13 are rotatably connected to the outer side of the cross plate 12.

[0024] When desilting the sewage pipe, firstly, a traction structure is set at both ends of the sewage pipe, and then the desilting device is connected to the traction mechanism, so that the auxiliary roller 13 on the outer side of the cross plate 12 assists the desilting device to move in the sewage pipe under the action of the traction mechanism. During the desilting process, the rotating disk 3 is driven to rotate inside the sewage pipe by the rotating assembly, so that the arc-shaped scraper 4 on one side of the rotating disk 3 continuously scrapes off the silt adhered to the inner wall of the sewage pipe, and the scraped silt moves outside the rotating disk 3 and is sucked by the sludge pump 16. The silt falls into the sewage drawer 11 in the collection box 2 through the collecting hole 23 and the collecting tube 14. After a certain amount of dredging work in the sewage pipe is completed, the lock of the sewage drawer 11 is released by the self-locking component, and then the staff removes the sewage drawer 11 from the inner drawer of the embedded groove 17 and cleans it. This makes it convenient for the dredging device to scrape off the silt inside the sewage pipe and collect it centrally at the same time. After a certain amount of dredging work is completed, the self-locking component is used for centralized processing, thereby improving the dredging efficiency of the sewage pipe by the dredging device.

[0025] like Figure 1-Figure 5 As shown, the rotating assembly includes a mounting plate 8, which is fixedly connected to the top of the function box 1. A power motor 9 is fixedly installed on one side of the mounting plate 8. The output end of the power motor 9 passes through the mounting plate 8 and is fixedly connected to a gear 7. The outer side of the connecting tube 5 is fixedly connected to a gear ring 6, and the tooth edge of the gear ring 6 is meshed with the outer side of the gear 7.

[0026] The power motor 9 drives the gear 7 to rotate, so that the gear 7 drives the connecting tube 5 and the turntable 3 to rotate simultaneously through the gear ring 6. The turntable 3 rotates so that the arc-shaped scraper 4 on the outer side of the turntable 3 continuously scrapes away the silt adhered to the inner wall of the sewage pipe, thereby improving the dredging efficiency of the dredging device for the sewage pipe.

[0027] like Figure 1-Figure 5 As shown, the self-locking assembly includes a locking box 10, which is fixedly connected to the outer side of the collection box 2, and a movable plate 18 is slidably connected between the inner walls of the locking box 10, and a block 22 is fixedly connected to one side of the movable plate 18, and one end of the block 22 extends to the outer side of the locking box 10, and a connecting rod 19 is fixedly connected to the other side of the movable plate 18. A spring 20 is fixedly connected to the outer side of the connecting rod 19 and located between the movable plate 18 and the inner wall of the locking box 10, and one end of the connecting rod 19 extends to the outer side of the locking box 10 and is fixedly connected to an adjusting block 21, and a slope structure is provided on one side of the block 22.

[0028] The staff pulls the adjustment block 21, so that the adjustment block 21 drives the card block 22 to move toward the inside of the locking box 10 through the connecting rod 19 and the movable plate 18, thereby facilitating the unlocking of the sewage drawer 11, and then the staff can quickly remove the sewage drawer 11 from the inside of the embedded groove 17 and clean it, thereby reducing maintenance time and improving the use efficiency of the device.

[0029] The utility model provides a dredging device for a sewage pipe, and the specific working principle is as follows: when dredging the sewage pipe, firstly, a traction structure is set at both ends of the sewage pipe, and then the dredging device is connected to the traction mechanism, so that the auxiliary roller 13 on the outer side of the cross plate 12 assists the dredging device to move in the sewage pipe under the action of the traction mechanism. In the dredging process, the power motor 9 drives the gear 7 to rotate, so that the gear 7 drives the connecting tube 5 and the rotating disk 3 to rotate at the same time through the gear ring 6, so that the arc-shaped scraper 4 on the outer side of the rotating disk 3 continuously rotates. The sludge adhered to the inner wall of the sewage pipe is scraped off, and the scraped sludge will move to the outside of the turntable 3 and fall into the sewage drawer 11 in the collecting box 2 through the collecting hole 23 and the collecting pipe 14 under the suction of the sludge pump 16. After a certain amount of sewage pipe dredging work is completed, by pulling the adjusting block 21, the adjusting block 21 drives the card block 22 to move toward the inside of the locking box 10 through the connecting rod 19 and the movable plate 18, thereby facilitating the unlocking of the sewage drawer 11, and then the sewage drawer 11 is removed from the inner drawer of the embedded groove 17 by the staff and cleaned.
