[0027] As Figures 1 to 3 shown, the embodiment provides an overhead cable galloping monitoring device 100, which comprises a threading seat 10, a temperature detection member 50, and a galloping detection assembly 60.

[0028] The threading seat 10 is provided with a threading hole 21 for threading a cable, which can be an overhead ground wire or an overhead conductor. The temperature detection member 50 is configured to detect the temperature of the cable. The groove wall of the threading hole 21 is provided with a receiving groove 220, and the temperature detection member 50 is arranged in the receiving groove 220. The galloping detection assembly 60 is arranged in the threading seat 10, and the galloping detection assembly 60 is configured to detect the galloping state of the cable.

The elastic member 20 is arranged around the groove wall of the threading groove 11 and forms the threading hole 21, and the receiving groove 220 is arranged on the inner circumferential surface of the elastic member 20.

[0032] The threading seat 10 is made of aluminum-magnesium alloy. The aluminum-magnesium alloy has good hardness, high tensile and yield strength, and is suitable for lightweight load-bearing structural parts. The aluminum-magnesium alloy is easy to cut and suitable for shell manufacturing. The aluminum-magnesium alloy has a small density and is suitable for weight reduction design requirements of the overhead cable dancing monitoring device 100. In addition, the aluminum-magnesium alloy has good corrosion resistance in ordinary and conventional atmospheric environment. The surface of the threading seat 10 is subjected to anodizing and sandblasting treatment to enhance the corrosion resistance in a humid environment.

[0035] Along the first direction Z, the first threading seat 12 is provided with a plurality of first protrusions 124 on the side close to the second threading seat 13, and the second threading seat 13 is provided with a plurality of second protrusions 135 on the side close to the first threading seat 12. Along the second direction X, the plurality of first protrusions 124 and the plurality of second protrusions 135 are located on the same side of the threading groove 11. Along the third direction Y, the plurality of first protrusions 124 are spaced apart, and the plurality of second protrusions 135 are spaced apart, so that the plurality of first protrusions 124 and the plurality of second protrusions 135 are staggered and spaced apart.

[0036] The first protrusion 124 is provided with a first rotating hole 1240, and the second protrusion 135 is provided with a second rotating hole 1350.
