Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a pipe inner wall cleaning device. Background Technology

[0002] Pipelines are widely used in industrial production and daily life to transport various fluid media such as water, oil, and gas. Over time, dirt, rust, deposits and other impurities will gradually accumulate on the inner wall of the pipeline. This will not only reduce the flow cross-sectional area of ​​the pipeline and reduce the fluid transport efficiency, but may also lead to pipeline corrosion, blockage and even safety accidents. The pipeline cleaning devices currently used can only be used for a certain fixed pipeline inner diameter and are time-consuming, labor-intensive and inefficient. Therefore, there is a need for a new type of pipeline inner wall cleaning device that can adapt to different pipeline inner diameters and is time-saving, labor-saving and highly efficient.

The cleaning platform 1 has an "L"-shaped structure and the wheels 2 are fixed with screws at the bottom. The operation panel 3 is fixed with screws at the middle of the left front end of the cleaning platform 1. The lead screw 4 with an embedded structure is installed at the middle of the right end of the cleaning platform 1 and is connected by a bearing hinge. The first servo motor 5 is installed at the middle of the left top of the cleaning platform 1 and at the top of the lead screw 4. The adjustable cleaning device 6 is installed at the right end of the surface of the lead screw 4. The contaminant collection tank 7 is opened at the right top of the cleaning platform 1 and below the adjustable cleaning device 6. The guide wheels 8 are symmetrically distributed at equal intervals inside the contaminant collection tank 7. The filter holes 9 are symmetrically distributed at equal intervals around the guide wheels 8.

[0015] The adjustable cleaning device 6 includes a hydraulic cylinder mounting bracket 10, a connecting bracket 11, a movable nut 12, a multi-stage hydraulic cylinder 13, a gear mounting bracket 14, a drive gear 15, a second servo motor 16, a driven gear 17, and a rotating cleaning frame 18. The hydraulic cylinder mounting bracket 10 has a screw-fixed connecting bracket 11 mounted on its left end. The top left end of the connecting bracket 11 has a nested screw-fixed movable nut 12, which is nested on the surface of the lead screw 4 and connected by threads. The right inner side of the hydraulic cylinder mounting bracket 10 has an embedded bolt-fixed multi-stage hydraulic cylinder 13. The right end of the multi-stage hydraulic cylinder 13 has a bolt-fixed gear mounting bracket 14. The right inner side of the gear mounting bracket 14 has a hinged drive gear 15. The middle left end of the drive gear 15 has a key-connected second servo motor 16. Below the drive gear 15 is a meshing driven gear 17. The middle right end of the driven gear 17 has a welded drive shaft with the rotating cleaning frame 18 nested on its surface.

[0016] The rotating cleaning frame 18 includes a connecting sleeve 19, a fixed base 20, a locking nut 21, a movable rod 22, a cleaning brush 23, and a cleaning scraper 24.

[0017] The working principle of this utility model is as follows: First, the pipe to be cleaned is hoisted to the top of the contaminant collection tank and above the guide wheel. Then, the first servo motor is controlled by the operation panel to drive the lead screw to rotate. During the rotation of the lead screw, it cooperates with the moving nut to convert the rotational motion of the first servo motor into the lifting motion of the connecting frame, thereby realizing the height adjustment of the adjustable cleaning device to adapt to different pipe inner diameters. Then, the horizontal position of the rotating cleaning frame inside the pipe is adjusted by a multi-stage hydraulic cylinder. In conjunction with the second servo motor, the right-end drive gear rotates. The drive gear meshes with the driven gear below, thereby driving the rotating cleaning frame to rotate. In conjunction with the multi-stage hydraulic cylinder, the rotating cleaning frame moves horizontally in a spiral motion. At the same time, while the rotating cleaning frame moves spirally inside the pipe, the cleaning brush and cleaning scraper clean the contaminants on the inner wall of the pipe. The fixed base and movable rod on the surface of the connecting sleeve adjust the position of the cleaning brush and cleaning scraper relative to the inner wall of the pipe for better cleaning of the inside of the pipe. Finally, with the additional water gun, the cleaned contaminants are rinsed into the contaminant collection tank and filtered through the filter holes to remove contaminants and wastewater.
