Nondestructive detection device

Abstract

The invention provides a nondestructive detection device. The device comprises a mounting plate, detection mechanisms arranged on the mounting plate, adsorption crawling mechanisms, damping mechanisms, and a signal control mechanism, wherein the mounting plate is provided with a first side surface, a second side surface, a first surface and a second surface; each detection mechanism comprises a magnetic memory detection unit which can adhere to a detection surface for acquisition of magnetic memory signals; each adsorption crawling mechanism comprises a crawling assembly and a driving assembly, and the driving assembly can drive the crawling assembly to carry out adsorption crawling along the detection surface; the adsorption crawling mechanisms are rotatably arranged on the first side surface and the second side surface; each damping mechanism comprises a first guiding piece and an outer frame, and the first guiding piece is arranged in the frame, penetrates the mounting plate in thedirection from the first surface to the second surface, and is sleeved by a first elastic piece; and the signal control mechanism comprises an acquisition assembly and an adjustment and control assembly. The detection device provided by the invention has the advantages that the magnetic memory signals can be stably acquired through the magnetic memory detection technology, so that automatic detection can be achieved without production suspension and tank opening.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a nondestructive detection device. Background technique [0002] The storage tank is the storage container for the medium transported by the long-distance oil and gas pipeline, and it is one of the most common equipment in the petrochemical industry. During the use of the storage tank, under the long-term interaction between the corrosive substances in oil and natural gas and the inner wall of the storage tank, metal loss is likely to occur, and the inner wall of the storage tank is prone to defects such as depressions, cracks, and holes. Once the tank wall is perforated, it will Cause oil and gas leaks and other accidents, resulting in serious safety and environmental disasters. Therefore, it is necessary to conduct regular inspections on the corrosion failure and protection of the tank. [0003] In the existing technology, storage tank inspection usually requires shutting d...

AI Technical Summary

Problems solved by technology

There are problems such as complex operating procedures, low operating efficiency, high inspection costs, and low defect quantitative positioning accuracy

In addition, because the medium in the storage tank is usually flammable, explosive, and corrosive, there are greater risks in the operations of pouring, cleaning, and testing.
