Problems solved by technology

[0002] Due to the relationship between thermal expansion and cold contraction of high-voltage overhead lines, the line is often not erected in a straight line, but is erected in an arc between two towers to prevent it from being broken during the process of cold contraction. The distance between the lowest point of the cables and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage cables, resulting in dangerous accidents. Therefore, power supply management and control companies often use h

Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, the power system cable wear-free embedded suspension and warning device according to the present invention includes a sign 1, an inner ball 2 and an outer ball 3, the inner ball 2 is an inner sphere, and is connected to the sign by a connecting rod 4 The top of 1 is connected; the top of the outer ball 3 is fixed on the cable through the fixing device 11, the inner ball 2 is located in the outer ball 3, and the outer ball 3 is provided with an opening 5 for the connecting rod 4 to pass through.

Embodiment 2

[0024] Embodiment 2: on the basis of the structure described in embodiment 1, as figure 2 As shown, the hollow part of the outer ball 3 is a semicircular hollow 6 with the same diameter as the outer ball and concentric, the opening 5 corresponds to the curved surface of the semicircular hollow 6, and the thickness of the semicircular hollow 6 is adapted to the connecting rod 4 , the semicircular hollow 6 is provided with a circular "T" channel 7, the horizontal part of the "T" channel 7 is centered on the diameter of the semicircular hollow 6, and the vertical part is a semicircle perpendicular to the diameter. The radius of the hollow 6 is the center, and the vertical part of the "T" channel 7 does not communicate with the opening 5.

Embodiment 3

[0025] Embodiment 3: On the basis of the structure described in Embodiment 2, the top and bottom of the horizontal part of the "T" channel 7 are provided with arc-shaped recesses 9, and the horizontal part of the "T" channel 7 is provided with a "U" Type latch 8, "U" type latch 8 is respectively provided with a protrusion 10 adapted to the arc-shaped recess 9 up and down.

Abstract

The invention provides an embedded-hanging warning device without abrasion for cables of electric power system, and belongs to the field of direction boards of overhead lines. The embedded-hanging warning device comprises a direction board, an internal ball and an external ball, the internal ball is an internal ball body which is connected with the top of the direction board. The top of the external ball is fixed to a cable through a fixing device, the internal ball is arranged in the external ball, the external ball is provided with an opening where the connecting rod passes through. The embedded-hanging warning device does not wear the cable, and make the cable swing.

Description

technical field [0001] The invention provides a wear-free embedded suspension and warning device for cables in a power system, which belongs to the field of warning signs for overhead lines. Background technique [0002] Due to the relationship between thermal expansion and cold contraction of high-voltage overhead lines, the line is often not erected in a straight line, but is erected in an arc between two towers to prevent it from being broken during the process of cold contraction. The distance between the lowest point of the cables and the ground is often very low. When larger equipment passes by at night, it is likely to encounter high-voltage cables, resulting in dangerous accidents. Therefore, power supply management and control companies often use hanging rings to The signboard is hung on the overhead line. When the signboard is blown by the wind, it will swing back and forth. The purpose of using the hanging ring is to avoid the fixed connection between the signboar...
