Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and in particular to a device and method for cleaning dirt inside a pipeline. Background Art

[0002] Pipelines are widely used in industrial production and civil sectors. The use of pipelines to transport gas, liquid and other fluids has many advantages such as convenience, speed and low cost. However, for horizontally set pipelines, dirt will be deposited on the bottom of the inner wall of the pipeline during long-term use. For example, in a drainage pipe, when water flows through the pipe, due to the slow water flow rate at the bottom of the pipe, small particles floating in the water are easily deposited at the bottom of the pipe, forming dirt accumulation. The aging of pipelines in old communities, long service life and accumulated dirt in the pipes will also cause the pipe diameter to become smaller, further aggravating the accumulation of dirt. In addition, coking and carbon deposition and other dirt will also form in industrial gas pipelines. These dirt deposits in the pipelines greatly increase the resistance of gas and liquid fluids during transportation, which not only reduces the transmission efficiency, but also greatly increases the power energy consumption required for conveying the fluid. The dirt will also corrode and damage the pipeline materials. In severe cases, the pipeline will rupture, and the conveyed fluid will leak out, causing losses and damage to equipment, seriously affecting economic benefits.

[0003] Most of the pipe cleaning devices in the prior art are equipped with a rotatable cleaning part at the end, which cleans the dirt on the inner wall of the pipe by a rotating brush. Although this structure can easily clean dust and other dirt on the upper part of the inner wall of the pipe, when the dirt at the bottom of the pipe is relatively hard or adheres firmly to the inner wall of the pipe, it is not easy to clean it with a rotating brush, and the brush may be damaged due to collision when it contacts foreign objects, which wastes manpower and material resources. In addition, some pipe cleaning devices can only scrape off the dirt in the pipe, and it is not easy to collect and transfer it outside the pipe, which is generally flushed with water.

The output shaft of the scraping motor 46 rotates, driving the driving gear 461 to rotate, and the driven gear 462 meshing with the driving gear 461 rotates. The driven gear 462 drives the eccentric wheel 464 to rotate through the connecting shaft 463. Under the action of the eccentric wheel, the support column 45 drives the bucket 41 to make a reciprocating linear motion to scrape the adhered dirt; S4: The dirt in the discharge plate 321 enters the feeding frame 34 along the inclined surface, and the feeding motor 341 drives the feeding screw rod 342 to rotate, so as to transport the dirt in the feeding frame 34 to the storage box 14, and at the same time, the crushing blocks on the outer side of the feeding screw rod 342 crush the dirt; S5: After completing a cleaning operation, start the limiting hydraulic cylinder 131 to separate the limiting protrusion 132 at the end of the piston rod from the limiting block 142, and then take out the storage box 14 containing dirt and replace it with a new storage box 14.

8. A device for cleaning dirt inside a pipeline according to claim 2, characterized in that: A semicircular support ring is fixedly provided at one end of the containing shell away from the feed shell, a cleaning block is slidably provided on the support ring, an annular rack is provided on the inner surface of the support ring, a cleaning gear is rotatably provided on the inner lower part of the cleaning block, the cleaning gear is meshed with the rack, a cleaning motor is provided on the side surface of the cleaning block close to the feed shell, and the output shaft end of the cleaning motor is fixedly connected to the cleaning gear.

9. A device for cleaning dirt inside a pipeline according to claim 8, characterized in that: A cleaning plate is fixedly provided on the outer surface of the cleaning block, and the outer surface of the cleaning plate contacts the inner wall of the pipeline. The outer surface of the bucket contacts the inner wall of the pipeline and is slidably connected. Tightening hydraulic cylinders are provided on both sides of the outer wall of the conveying shell, and a tightening block is fixedly provided on the end of the piston rod of the tightening hydraulic cylinder, and the tightening block abuts against the inner wall of the pipeline.

10. A method for cleaning dirt inside a pipeline, applied to a device for cleaning dirt inside a pipeline as claimed in any one of claims 1 to 9, characterized in that: The specific steps are as follows: S1: Place the device with one end of the bucket facing the inside of the pipeline, start the cleaning motor, the digging motor and the feeding motor, and drive the entire device to move along the inner wall of the pipeline by the external driving structure; S2: The bucket removes the solid dirt at the bottom of the pipe, and the dirt enters the feed shell along the bucket. Under the action of the digging motor, the bucket of the material transport part digs the dirt in the feed shell and transfers the excavated dirt to the discharge plate as the material transport part rotates. At the same time, the cleaning motor drives the cleaning block to clean the area on the upper part of the inner wall of the pipe, and the fallen dust enters the feed shell through the bucket; S3: When encountering relatively hard dirt or dirt that is firmly attached to the inner wall of the pipe, the scraping motor is started, and the scraping motor drives the eccentric wheel to rotate through the gear transmission. Under the action of the eccentric wheel, the bucket makes reciprocating linear motion to remove the attached dirt; S4: The dirt in the discharge plate enters the feeding frame along the inclined surface. The feeding screw rod, under the action of the feeding motor, transports the dirt in the feeding frame to the storage box. At the same time, the crushing block on the outside of the feeding screw rod crushes the dirt. S5: After completing a cleaning work, start the limit hydraulic cylinder to separate the end of its piston rod from the limit block, then take out the storage box containing dirt and replace it with a new storage box.
