Description

Diameter-variable pipe cleaner

Technical Field

The utility model belongs to the technical field of the dredging pipe ware, concretely relates to dredging pipe ware of variable footpath.

Background

In the early pipeline construction process in China, a large number of steel and cast iron pipes are used, such as: urban water supply pipe, drainage pipe, oil and gas pipeline etc. these pipelines all have inside corrosion, scale deposit phenomenon after long-term operation, and inside has a large amount of rusts and scales, and serious influence pipeline overflows efficiency, and structural strength descends after the pipeline structure receives to corrode, takes place to explode the pipe very easily, breaks, accident such as sink leads to the pipeline function to become invalid. When the pipeline cannot meet the operation requirement due to the problems, the pipeline is usually cleaned regularly or replaced by a large excavation method. There are many drawbacks in adopting the construction of digging greatly, if: to city resident life and trip influence great, construction security is poor, dust noise and pollution incident frequent etc. in recent years, along with the introduction and the popularization and application of "non-excavation" technique, the pipeline is restoreed and is updated and has had more, better selection, if: trenchless lining repairing technology, spraying repairing technology and the like. But when the pipeline is repaired by adopting the 'non-excavation' technology, the original old pipeline also needs to be cleaned, and foreign matters such as scale formation, rusty tumors and the like in the pipeline are removed; the use of a pulling pig to remove foreign matter from the inner wall of a pipe is one of the most common means.

In the chinese patent with the publication number CN213701083U, a diameter-variable pipe cleaner is disclosed, which comprises a base, a screw shaft, a diameter-variable adjusting plate, a brush head support rod and a pipe cleaning brush; a screw shaft capable of rotating along the vertical direction is arranged at the upper end of the base; the reducing adjusting plate is arranged on the screw shaft and can move up and down along with the rotation of the screw shaft, at least two supporting plate limiting holes distributed along the circumference are arranged on the reducing adjusting plate, and the supporting plate limiting holes are inclined holes with the bottoms inclined towards the direction of the screw shaft.

However, after the diameter is adjusted by the technical scheme, the brush head support rod can be in an inclined state, only one group of the cleaning brushes at the tail part of the brush head support rod can be in contact with the inside of the pipeline, and the inclination of the brush head support rod can enable the cleaning brushes to be inclined, so that only one corner edge of one group of the cleaning brushes at the tail part of the support rod can be in contact with the inner wall of the pipeline, and the pipeline cleaning effect is poor.
