Description

Technical Field

[0001] The utility model relates to the technical field of pipeline inner wall cleaning, in particular to a pipeline cleaning device for pipeline repair. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. After years of use, some pipelines have frequent leakage and rupture accidents. Most of these pipelines are laid in densely populated and prosperous urban areas. Excavation and construction will cause traffic jams and damage to green spaces and gardens. Some pipelines have small diameters and no working surface, making it impossible for personnel to enter the pipelines to carry out repairs.

[0003] Among them, the interlaced method of pipeline repair is to use the space of the pipeline to be repaired and pull a new PE pipe into the pipeline to be repaired to form a pipe in a pipe. However, before construction, since a large amount of garbage will remain in the internal pipeline after long-term use, it is necessary to use a special pipeline cleaning device to clean the inside of the pipeline. Currently, high-pressure water jet cleaning equipment is mostly used to clean the pipeline. However, using only high-pressure water jet cleaning equipment to clean the inner wall of the pipeline has the following disadvantages: (1) High-pressure water washing cannot completely remove the adhesive in the pipeline by relying on the impact force of water pressure, such as hard blocks with strong stickiness, etc., resulting in the new PE pipe being scratched by the hard blocks after being pulled into the pipeline to be repaired, affecting the repair effect; (2) For the dirt and adhesive at the corners of the pipeline, the operator cannot accurately clean the dirt at the pipeline using only high-pressure water jet. In response to the above shortcomings, those skilled in the art have proposed a pipeline cleaning device for pipeline repair. Utility Model Content

It includes a drive component 1, which includes a threaded column 11, and a drive block 12 is slidably sleeved on the threaded column 11. One end of the threaded column 11 is coaxially connected to the motor 13, and the other end of the threaded column 11 is integrally welded with a limit block, and the limit block plays an adjusting and limiting role for the drive block 12. A bearing 14 is provided on the output shaft of the motor 13. The outer walls of the drive block 12 and the bearing 14 are fixedly provided with a mounting ring 2, and the outer wall of the mounting ring 2 is evenly distributed around the circumference. A shell 3 is fixedly provided on the side of the mounting ring 2 on the outer wall of the bearing 14, and the motor 13 is fixedly provided in the shell 3.

[0034] In order to make the device applicable to pipes of different sizes, in this embodiment, see Figure 2 and Figure 3 A plurality of adjustment assemblies 4 are provided between the two mounting rings 2. The adjustment assemblies 4 include adjustment rods 41, each hinged to a corresponding hinge seat 21 of the two mounting rings 2. A mounting block 42 is hinged at the other end of the two adjustment rods 41. The crawler 7 is detachably fixedly mounted on the mounting block 42, and a drive member is provided within the crawler 7. The motor 13 can be used to drive the threaded column 11 to rotate, thereby changing the position of the drive block 12, thereby changing the hinge distance between the adjustment rods 41 on the hinge seats 21 on both sides. The position of the crawler 7 at the bottom of the mounting block 42 can be adjusted to accommodate pipes of different sizes. The crawler 7 moves in contact with the inner wall of the pipe, allowing precise cleaning of the pipe interior and corners.

[0035] In order to make the cleaning component of the device work stably, in this embodiment, see Figure 2 A connecting assembly 5 is fixedly provided on the shell 3, and the connecting assembly 5 includes a connecting rod 51. One end of the connecting rod 51 is fixedly provided on the outer wall of the shell 3. A plurality of connecting rods 51 are provided and are evenly distributed on the circumference of the shell 3. A connecting disk 52 is fixedly provided on the other end of each connecting rod 51.

[0036] In order to efficiently clean the pipeline, in this embodiment, see Figure 2 、 Figure 4 、 Figure 5 and Figure 6A cleaning assembly 6 is provided on the connecting plate 52. The cleaning assembly 6 includes a water spray mechanism 61, and the water spray mechanism 61 includes a connecting pipe 611. The connecting pipe 611 is fixedly disposed in a mounting groove in the connecting plate 52. The water inlet of the connecting pipe 611 is connected to an external high-pressure water pump through a pipeline, and the high-pressure water pump is also provided with a pressurizing device.

[0037] The water outlet of the connecting pipe 611 is sealedly connected to the linkage pipe 612 via a rotating connector. A limiting stabilizing column 615 is fixedly sleeved on the linkage pipe 612. The limiting stabilizing column 615 is a combination of a regular hexagonal column structure and a circular plate structure, and the diameter of the circular plate is larger than the diameter of the regular hexagonal column. The water outlet of the linkage pipe 612 is detachably fixedly connected to the water storage box 613. A high-pressure nozzle 614 is detachably fixedly installed on the side wall of the water storage box 613. Two high-pressure nozzles 614 are provided, and the two high-pressure nozzles 614 are symmetrically arranged on the side wall of the water storage box 613 with the center of the water storage box 613. The cleaning component 6 also includes a cleaning disc 62, the center of which has a hole of the same size as the hexagonal column. When cleaning pipes of different sizes, the water storage box 613 can be removed first, and a cleaning disc 62 of the corresponding size can be selected and mounted on the limiting stabilizing column 615. The water storage box 613 can then be fixedly installed on the linkage pipe 612 so that the cleaning disc 62 is fixedly limited between the water storage box 613 and the circular plate of the limiting stabilizing column 615. The water spraying mechanism 61 is turned on, and the kinetic energy of the water flow in the centrally symmetrical high-pressure nozzles 614 on both sides is converted into the rotational kinetic energy of the water spraying mechanism 61, thereby driving the cleaning disc 62 to rotate, and the adhesive in the pipe is removed through the cooperation of the high-pressure nozzles 614 and the cleaning disc 62.

[0038] The method of using the pipeline cleaning device for pipeline repair of the present invention is as follows: the threaded column 11 can be driven to rotate by the motor 13 to change the position of the driving block 12, thereby changing the hinge point distance of the adjustment rod 41 on the hinge seat 21 on both sides, and adjusting the position of the crawler 7 at the bottom of the mounting block 42 to adapt to pipelines of different sizes. When cleaning pipes of different sizes, the water storage box 613 can be removed first, and a cleaning disc 62 of the corresponding size can be selected and placed on the limiting stabilizing column 615. The water storage box 613 is then fixedly installed on the linkage pipe 612, so that the cleaning disc 62 is fixedly limited between the water storage box 613 and the circular plate of the limiting stabilizing column 615. The water spray mechanism 61 is turned on, and the kinetic energy of the water flow in the high-pressure nozzles 614, which are symmetrical on both sides, is converted into the rotational kinetic energy of the water spray mechanism 61, thereby driving the cleaning disc 62 to rotate. The high-pressure nozzles 614 and the cleaning disc 62 cooperate to remove adhesives in the pipe. The crawler 7 contacts the inner wall of the pipe and moves, accurately cleaning the inside of the pipe and the corners, improving the cleanliness of the inner wall of the pipe, avoiding over-cleaning, helping to save resources and reduce costs. The improvement of the cleanliness of the inner wall of the pipe reduces the strong sticky hard blocks in the pipe, and reduces the chance of scratching the new PE pipe by the hard blocks during pipe repair, thereby improving the effect of pipe repair.
