Description

Technical Field

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

[0002] Pipelines are widely used in industrial production and civil sectors. Transporting gas-liquid materials through pipelines has many advantages such as convenience, speed, and low cost. For horizontally arranged pipelines, during long-term use, dirt will accumulate on the bottom inner wall of the pipeline. For example, in drainage pipelines, when water flows through the pipeline, due to the slow water flow speed at the bottom of the pipeline, small particles floating in the water are likely to deposit on the bottom of the pipeline, forming dirt accumulation. In addition, the aging of pipelines in old residential areas, long service life, and accumulated dirt in the pipeline will also cause the pipe diameter to become smaller, further exacerbating the dirt accumulation. Moreover, in industrial gas pipelines, dirt such as coking and carbon deposition will also form. The deposition of this dirt in the pipeline greatly increases the resistance of the gas-liquid fluid during transportation, not only reducing the transmission efficiency, but also greatly increasing the power energy consumption required for transporting the fluid. The dirt will also cause corrosion and damage to the pipeline material. In severe cases, the pipeline will burst, resulting in the leakage of the transported fluid and causing losses, damaging equipment, and seriously affecting economic benefits.

[0003] In the prior art, most pipeline cleaning devices are equipped with rotatable cleaning parts at the ends, and the dirt on the inner wall of the pipeline is cleaned by rotating brushes. Although this structure can easily clean dirt such as dust on the upper part of the inner wall of the pipeline, when the dirt at the bottom of the pipeline is relatively hard or adheres firmly to the inner wall of the pipeline, it is not easy for the rotating brush to clean it. Moreover, the brush may be damaged due to collision when contacting foreign objects, consuming manpower and material resources. In addition, some pipeline cleaning devices can only scrape the dirt inside the pipeline and are not easy to collect and transfer it outside the pipeline, usually using water flow to wash.

When the device cleans firmly adhered dirt, the tightening block 122 can keep the device relatively fixed with the pipeline, preventing the bucket 41 from causing the device to move when removing dirt and affecting the dirt removal effect.

[0050] A method for cleaning dirt inside a pipeline is applied to the above-mentioned device for cleaning dirt inside a pipeline. The specific steps are as follows:

[0051] S1: Orient the end of the device with the bucket 41 towards the inside of the pipeline and place it inside the pipeline. Start the cleaning motor 231, the material digging motor 33, and the material conveying motor 341. The entire device is driven by an external driving structure to move along the inner wall of the pipeline.

[0052] S2: The bucket 41 shovels the solid dirt at the bottom of the pipeline. The dirt passes along the inclined surface of the bucket 41 through the connecting plate 47 and enters the feeding shell 11. Under the action of the material digging motor 33, the second transmission wheel 331 drives the first transmission wheel 313 to rotate through belt transmission. The first transmission wheel 313 drives the material conveying member 31 to rotate. The digging bucket 311 of the material conveying member 31 digs the dirt in the feeding shell 11. When the digging bucket 311 filled with dirt rotates above the discharging plate 321 as the material conveying member 31 rotates, the dirt in the digging bucket 311 falls into the discharging plate 321 and enters the material conveying frame 34 along the inclined surface in the discharging plate 321. At the same time, the cleaning motor 231 drives the cleaning gear 232 to rotate. The cleaning gear 232 moves along the rack 222, driving the cleaning block 23 to clean the area above the inner wall of the pipeline. The fallen dust also enters the feeding shell 11 together with the bucket 41.

[0053] S3: When encountering dirt that is relatively hard or firmly adhered to the inner wall of the pipeline, stop the wheels from rotating. Start the tightening hydraulic cylinder 121. The end of the piston rod of the tightening hydraulic cylinder 121 extends, driving the tightening block 122 to abut against the inner wall of the pipeline. Start the shoveling motor 46. The output shaft of the shoveling motor 46 rotates, driving the driving gear 461 to rotate. 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 perform a reciprocating linear motion to shovel the adhered dirt.

[0054] S4: The dirt inside the unloading plate 321 enters the material conveying frame 34 along the inclined plane. The material conveying motor 341 drives the material conveying screw rod 342 to rotate, transporting the dirt in the material conveying frame 34 into the storage tank 14. Meanwhile, the crushing blocks outside the material conveying screw rod 342 crush the dirt.

[0055] S5: After completing one cleaning operation, start the limit hydraulic cylinder 131 to separate the limit convex block 132 at the end of its piston rod from the limit block 142, and then take out the storage tank 14 filled with dirt and replace it with a new storage tank 14. In this method, the firm dirt is cleaned by the reciprocating bucket 41, the dirt such as dust is cleaned by the reciprocating cleaning block 23, and the cleaned dirt is transported by the material transporting member 31, the unloading member 32 and the material conveying screw rod 342. The whole device integrates cleaning and collection, has greater applicability, and reduces the waste of water resources caused by flushing the pipeline dirt with a large amount of water.

8. 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 7, 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 wheel stops rotating, the tightening hydraulic cylinder is started, the piston rod end of the tightening hydraulic cylinder extends, driving the tightening block to contact the inner wall of the pipe, and the scraping motor is started. The scraping motor drives the eccentric wheel to rotate through the gear transmission, and the bucket makes a reciprocating linear motion under the action of the eccentric wheel to scrape 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.
