Description

Technical Field

[0001] The invention relates to the technical field of anti-corrosion treatment, and in particular to a gas transmission pipeline anti-corrosion coating spraying construction device. Background Art

[0002] Gas transmission pipelines need to undergo anti-corrosion construction, which is usually carried out by spraying anti-corrosion coatings on the inner and outer walls of the gas transmission pipelines through a construction device. The Chinese utility model patent with publication number CN218475528U proposes an engineering pipeline anti-corrosion construction device, which places the construction device inside the pipeline, and then the supporting moving wheel contacts the inner wall of the pipeline. The anti-corrosion liquid in the container gradually flows down from the leakage hole. These anti-corrosion liquids reach the inner wall of the pipeline, and then the rotating rod is in a rotating state, thereby brushing the inner wall with a brush so that the anti-corrosion liquid is evenly applied to the inner wall of the pipeline.

[0003] However, the above-mentioned prior art first allows the anti-corrosion liquid in the container to flow onto the inner wall of the pipe and then uses a brush to apply it. Since the flow speed of the anti-corrosion liquid is uncontrollable, the thickness of the anti-corrosion coating on the inner wall of the pipe is uneven. In addition, since a brush is used for application, a large number of wavy stripes will be generated on the surface of the coating on the inner wall of the pipe, which increases the resistance during gas transportation, so it needs to be improved.
