Device used for detecting defects of attached layers of iron-based sealing container

Abstract

The invention discloses a device used for detecting defects of attached layers of an iron-based sealing container, and mainly aims at providing the device capable of carrying out automated nondestructive testing for detecting whether the attached layers on the inner wall and on the outer wall of the iron-based sealing container have the defects. The device is characterized by comprising an outer shell body, a walking mechanism, an attached layer detecting mechanism and a control mechanism. The walking mechanism, the attached layer detecting mechanism and the control mechanism are fixed in the outer shell body, the front end of the outer shell body is provided with a groove, and a track-type walking wheel penetrates through the outer shell body. The attached layer detecting mechanism comprises a direct current dry valve electromagnet, an iron core push rod and a detection arm. The control mechanism is formed through connection of an STC12C5A60S2 core single chip computer, an upper computer, a wireless transmission module, a coded disc speed measuring module, a drive circuit current detecting module, an attached layer thickness detecting module, a motor, a drive module of the direct current dry valve electromagnet and the like. The device can replace people to finish the nondestructive testing of the defects of the attached layers on the inner wall and the outer wall of the iron-based sealing container in high-risk environments.

Description

technical field [0001] The invention relates to an automatic non-destructive detection device for detecting whether there are defects in the adhesion layer of the inner and outer walls of an iron-based closed container. Background technique [0002] Most of the closed tanks used for oil storage or water storage in industrial and mining, chemical companies and petroleum companies are iron-based closed containers. The inner and outer walls of these iron-based closed containers are coated differently depending on the working environment and the chemical nature of the contents. As a result, the quality of coating adhesion has become an important factor affecting the life and safety of iron-based closed containers, and the thickness of the coating has become a key parameter for examining the quality of coating adhesion. At present, the detection method for coating thickness is generally still through manual detection. For the quality inspection of wall coatings with a considera...

Problems solved by technology

This detection method not only has the disadvantages of high labor intensity for the operator, dangerous operation and low efficiency, but also the random inspection itself will cause damage to the inner and outer walls of the iron-based closed container.

In addition, since it is impossible for this manual detection method to randomly detect the coating thickness at any point in the iron-based closed container, the reliability of its detection results is low
