Description

Self-adaptive scraping blade type corrosiveness detection device for liquid level height in pipeline Technical Field The invention relates to the technical field of pipeline corrosiveness detection, in particular to a self-adaptive scraping blade type corrosiveness detection device for liquid level height in a pipeline. Background The detection of the pipeline corrosion is an important method for identifying and evaluating the metal loss inside and outside the pipeline, and aims to ensure that defects and damages can be found in time before serious problems occur to the pipeline, so that the pipeline can run safely for a long time. At present, when the pipeline is corroded to detect, because the liquid level department in the pipeline contacts air and pipeline wall simultaneously, lead to here the corruption that takes place to be most violent, but the pipeline is used at present to corrode the degree detection device, generally stretch into the pipeline with telescopic probe, look for and fix a position the liquid level height in the pipeline, detect the corruption degree of pipeline in liquid level department, seek the process of liquid level height comparatively loaded down with trivial details in this detection mode, be difficult to carry out quick location according to different liquid level heights for detection efficiency is lower, the pipeline of different diameters different wall thicknesses is difficult to detect with the corrosiveness detection device at present simultaneously. On the other hand, the patent with the search bulletin number of CN110220947B discloses a method for determining the corrosion degree of a pipeline, and the device can reduce the requirement on electronic elements and improve the safety in flammable and explosive environments. However, most of the pipeline materials are metal, and the liquid level in the pipeline is simultaneously contacted with air and the pipeline wall, so that a fluffy metal oxide layer appears at the position due to severe corrosion, if the position is directly observed through the detection head, the existence of corrosion can be detected, the corrosion degree of the inner wall of the pipeline at the position is difficult to rapidly and intuitively detect, and meanwhile, the inner ring of the pipeline is difficult to comprehensively detect, so that the corrosion degree detection effect of the pipeline is poor. Therefore, we provide a self-adaptive scraping blade type corrosiveness detection device for the liquid level height in a pipeline to solve the problems.
