A protective shell 7 is also installed on the sliding ring 3 to protect the detection end of the detection probe 2.

[0025] It should be noted that a spring 6 is provided on the limit rod 5, and one end of the spring 6 is fixedly connected to the sliding ring 3, and the other end of the spring 6 is fixedly connected to the fixed ring 4. Through the setting of the spring 6, the protective shell 7 can be squeezed through the elastic force of the spring 6. When the squeezing of the protective shell 7 is released, the protective shell 7 quickly rebounds under the action of the spring 6 to protect the detection probe 2.

[0026] Optional, see attached Figure 2 To Attachment Figure 4In this embodiment, in order to facilitate the detection of the detection probe 2 in the corrosion area, push rods 14 are installed on both sides of the sliding ring 3, and the bearing of the end of the push rod 14 away from the sliding ring 3 is connected to the roller 15. The push rod 14 is released from the corrosion area, so that the protective shell 7 can be separated from the detection probe 2, so that the detection probe 2 is exposed and contacts with the corrosion area for easy detection. Secondly, through the action of the roller 15, it is convenient to move on the detection surface of the steel bridge to avoid wear of the push rod 14.

[0027] It should be noted that when inspecting the corrosion area of ​​the steel bridge, the first protective cover 8 is first pulled out of the protective shell 7 to release the seal of the detection probe 2.

Through the setting of the annular slide rail 11 and the annular slide groove 12, it is convenient for the staff to rotate the second protective cover 9 externally, so that the second protective cover 9 can rotate in a circle, and the detection probe 2 is cleaned and protected by the brush 10 to avoid affecting the detection accuracy.

[0030] It should be noted that when cleaning the detection probe 2, under the action of the sliding connection between the slot and the slider 13, the first protective cover 8 is moved back and forth so that the brush 10 cleans the detection probe 2. In addition, the second protective cover 9 can be rotated to rotate the brush 10 to clean the detection probe 2.
