The flange connection is wrapped by the first absorbent cotton 5 and the second absorbent cotton 51. Since the first absorbent cotton 5 and the second absorbent cotton 51 have the characteristic of deformation effect, they can be adapted according to the shape of the flange to fit closely therewith. After the first absorbent cotton 5 and the second absorbent cotton 51 absorb water from the leaking place, data is collected under the action of the infrared detection rod 4 and sent to the PLC controller.

[0034] The protective shell 2 and the first absorbent cotton 5 are both arc-shaped structures, and the curvature of the protective shell 2 and the first absorbent cotton 5 are equal. Through the arc-shaped design of the protective shell 2 and the first absorbent cotton 5, the protective shell 2 can be adapted to the arc-shaped structure of the flange, and further the first absorbent cotton 5 is fitted with the flange connection to ensure the accuracy during detection.

[0035] There are two threaded rods 21 in total, and the two threaded rods 21 are symmetrical to each other at the center of the protective shell 2.
