Description

Technical Field

[0001] The utility model relates to the technical field of steel bar corrosion detection, in particular to a steel bar corrosion instrument. Background Art

[0002] As we all know, with the advancement of modern science and technology, the construction industry is also exploring scientifically, such as starting to study the steel material performance detection technology based on BP neural network. The corrosion of steel bars will affect the material properties of the steel bars, so it is often necessary to detect the degree of corrosion of the internal steel bars of the concrete structure. The steel bar corrosion meter is a commonly used detection instrument for detecting the degree of steel bar corrosion.

[0003] Usually, the steel bar corrosion tester includes a detection host, which is connected to a cylindrical detection electrode filled with saturated copper sulfate solution through a signal line. The detection electrode is provided with a detection end cap at the end away from the signal line, and a sponge strip is installed on the end cap. Before the test, the measuring point position is first determined, and then the sponge strip on the detection electrode is fully abutted against the measuring point according to the measuring point position. The test results will be displayed and stored in the detection host, and the test of all measuring points can be completed by analogy.

[0004] Regarding the above-mentioned related technologies, there are certain deficiencies in the inspection process. For example, a steel bar corrosion tester with application number CN202210651050.0 uses a handle to specify the distance between the two detection electrodes during inspection, so that the two electrodes are kept at a certain distance for corrosion inspection. If the detection distance is adjusted, the staff needs to replace the handles of different lengths. Therefore, it is inconvenient to replace the handles. At the same time, the staff needs to carry multiple handles of different lengths, which causes inconvenience to the staff. Utility Model Content
