Automatic pipeline-corrosion detecting device using concave phased array probe with adjustable curvature

Abstract

The invention discloses an automatic pipeline-corrosion detecting device using a concave phased array probe with adjustable curvature. The automatic pipeline-corrosion detecting device comprises a probe mechanism, which is composed of the probe and a water sleeve, wherein the water sleeve sleeves the probe; a probe fixing clamp, which is composed of a pedestal and magnetic sucking wheels, wherein the pedestal is connected with the probe and the magnetic sucking wheels are arranged on the pedestal; and a crawl device, which is composed of a crawl device body, a driving mechanism and driving magnetic wheels, wherein the crawl device body is connected with the probe fixing clamp, the driving mechanism and the driving magnetic wheels are arranged on the crawl device body, and the driving mechanism drives the driving magnetic wheels to move. The automatic pipeline-corrosion detecting device provided by the invention is light in design, applicable to detection of oil-conveying pipes of different pipe diameters, reduced in detection cost and improved in detection efficiency.

Description

technical field [0001] The invention relates to an automatic detection device for pipeline corrosion of a concave array phased array probe with adjustable curvature. Background technique [0002] Pipeline transportation is one of the five major transportation methods. It has a history of more than 100 years in the world. So far, crude oil pipeline transportation in developed countries accounts for 80% of the total transportation volume. 95%. [0003] The safety factors that endanger the oil pipeline mainly include the following aspects: [0004] 1. Natural disasters, which are unavoidable factors; [0005] 2. Man-made damage, which is a subjective and avoidable factor; [0006] 3. Pipeline corrosion, which is the most serious factor in the safety factors of pipelines, is an important problem that needs to be solved by technical means. [0007] Pipeline corrosion is widely highlighted in the transportation of petroleum pipelines, and it is an important issue to ensure the...

[0009] Among them, ultrasonic detection of pipeline corrosion is currently mainly performed by conventional ultrasonic probes and phased array concave array ultrasonic probes. Conventional ultrasonic probes have low detection efficiency, and phased array concave array ultrasonic probes are more convenient for detection, but different pipes need to be customized to match. Ultrasonic concave array phased array probe, this lack of versatility will lead to relatively high detection costs; and at present, most of the internal corrosion detection of oil pipelines using ultrasonic phased array probes is still in the manual detection stage, automatic detection cannot be realized, and the detection efficiency is relatively low.
