Surface detection device of nondestructive steel pipe

Abstract

The invention discloses an appearance detection device of a non-destructive steel pipe, which comprises a lifting rod and a control circuit board main body. Buttons and a display screen are installed on the control circuit board main body. The lower right side of the control circuit board main body is connected to the data transmission line, the data transmission line is connected to the moving mold cavity through the transmission device, and the inside of the moving mold cavity is provided with a data transmission line, a detection contact layer and a detection probe in sequence from the outside to the inside, and the main body of the control circuit board is electrically connected to the Buttons, display screens, data transmission lines, detection contact layers and detection probes. When a defect or the bottom surface of a part is encountered, it can be sensed by the detection probe inside the touch layer, and the information is transmitted to the main body of the control circuit through the data transmission line, and then displayed on the display screen. It is simple, intuitive, easy to operate, and highly portable, suitable for the field Long-distance working use. The test data can be backed up to facilitate data aggregation.

Description

technical field [0001] The invention relates to the technical field of steel pipe inspection equipment, in particular to an appearance inspection device for non-destructive steel pipes. Background technique [0002] With the adjustment of China's energy structure and the improvement of people's environmental awareness, in recent years, the proportion of the demand growth rate of natural gas in energy consumption has greatly exceeded that of crude oil. From 2006 to 2010, my country has built about 16,000Km of natural gas pipelines. In 2010 In 2019, my country has built about 45,000Km of natural gas pipelines. It is preliminarily estimated that by 2020, a national natural gas backbone pipeline network will be formed, and the proportion of natural gas consumption will increase from the current 3% to about 10%. Therefore, the safety of natural gas pipelines The problem has received extensive attention. Various methods are used at home and abroad to maintain, detect and monitor nat...

[0002] With the adjustment of China's energy structure and the improvement of people's environmental awareness, in recent years, the proportion of the demand growth rate of natural gas in energy consumption has greatly exceeded that of crude oil. From 2006 to 2010, my country has built about 16,000Km of natural gas pipelines. In 2010 In 2019, my country has built about 45,000Km of natural gas pipelines. It is preliminarily estimated that by 2020, a national natural gas backbone pipeline network will be formed, and the proportion of natural gas consumption will increase from the current 3% to about 10%. Therefore, the safety of natural gas pipelines The problem has received extensive attention. Various methods are used at home and abroad to maintain, detect and monitor natural gas pipelines. The existing gas pipeline testing equipment is huge and not suitable for outdoor use. At the same time, it is difficult to maintain such large testing equipment. Suitable for popularization and use, it can no longer meet people's needs for convenient and portable equipment
