Problems solved by technology

The traditional manual identification of welds can no longer meet the requirements of the rapid mass construction of cluster storage tanks, and the accuracy of defect identification of traditional manual identification of welds is greatly affected by the level of inspectors, and sometimes it cannot objectively reflect the true quality of welds. Defect rate, it is necessary to introduce artificial intelligence technology to intelligently identify and evaluate defects

Abstract

The invention relates to a storage tank weld defect automatic detection and recognition device which comprises a printing mechanism, a paper carrying mechanism and a film automatic recognition mechanism which are arranged in a shell, a control part is arranged at the top of the shell, and a storage mechanism is arranged at a lower part of the shell; the whole detection and recognition device is provided with an inlet, namely the automatic film recognition mechanism, an outlet, namely the paper carrying mechanism and a storage mechanism. The paper carrying mechanism is located over the storagemechanism. The output paper is conveyed to the storage mechanism under the control of a control system; the film automatic recognition mechanism is located obliquely above the storage mechanism, the automatic film recognition mechanism transmits a recognized film to the storage mechanism, film recognition information output by the automatic film recognition mechanism is transmitted into the control system, the control system controls the printing mechanism and the storage mechanism to work according to the received information, and the control part is connected with the control system. According to the invention, the storage, identification and printing of a storage tank weld joint film are realized, and the automation degree of storage tank weld joint detection is improved.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of storage tanks, in particular to an automatic detection and identification device for weld seam defects of storage tanks. Background technique [0002] Liquefied natural gas (LNG) is a methane-based liquid hydrocarbon mixture produced when natural gas is cooled to -162°C under normal pressure. Since the volume of liquefied natural gas is about 1 / 600, it is conducive to transportation and storage. Since the Dapeng LNG receiving terminal was put into operation in 2006, the longest operating time of China's LNG storage tanks has reached 11 years. At present, the number of domestic large-scale LNG storage tanks has reached more than 40, the cumulative import volume of LNG has exceeded 150 million tons, and domestic LNG receiving terminals have entered a period of rapid construction. [0003] The welding of X7NI9 steel plate is a key process in the quality control of the tank inner...
