[0002] At present, the durability test indicators of super-hydrophobic self-cleaning coatings in relevant technical standards are mainly xenon lamp aging, UV aging, outdoor rain mark test, etc., which are characterized by a long time consumption, which takes 1 to 3 months. Therefore, the coating apparent wear resistance is used in domestic and foreign research to quickly evaluate the durability of super-hydrophobic coatings, which has high applicability and convenience.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. By setting a fastening screw and a fastening nut, as well as a force sensor, the stress between the brush head and the surface of the super-hydrophobic coating can be effectively controlled, and the limitations of the brush head and the coating surface in a fixed direction can be overcome, so that the in-situ detection device can adapt to the wear resistance test of the super-hydrophobic coating surface in various directions. However, during use, super-hydrophobic coatings of different materials need to be detected with different detection brushes. Using a single detection brush for detection is likely to affect the detection accuracy.
