Description

Technical Field

[0001] This utility model relates to the field of line warning signs, and in particular to a safety device for overhead line warning signs. Background Technology

[0002] In the safe operation system of overhead power lines, warning signs play a crucial role as "safety sentinels," serving as the first line of defense in preventing accidents and ensuring the safety of personnel and equipment. Some overhead power lines cross roads, and because they are difficult to observe and their height is hard to judge, vehicles are prone to hitting them. Therefore, warning signs are necessary for observation and warning purposes. However, current warning signs still have the following problems in use: Currently, most warning signs are fixed to the cables, resulting in the signs being tied to the cables. The large cross-section of the warning signs causes them to sway violently in windy weather, causing the overhead power lines to swing significantly, affecting their usability and safety.

The bottom end of the guide rod 4 penetrates the bottom surface of the base plate 1 and is rotatably connected to a connecting top plate 12. A warning sign 13 is fixedly connected to the bottom surface of the connecting top plate 12. The warning sign 13 is made of flexible rubber. Spring rods 9 are fixedly connected to both sides of the center of the bottom of the base plate 1. A counterweight damping block 10 is fixedly connected to the end of each spring rod 9 away from the base plate 1.

[0021] As an optional technical solution of this utility model: a guide tube 3 is fixedly connected to the center of the bottom surface of the base plate 1, the top of the guide tube 3 penetrates the top surface of the base plate 1, and the guide rod 4 is a quadrangular prism structure and is slidably connected to the inner wall of the guide tube 3. By connecting the guide rod 4 through the guide tube 3, the guiding contact area can be increased and the stability of the guiding slide can be improved.

[0022] As an optional technical solution of this utility model: two spring rods 9 are fixedly connected to both sides of the outer wall of the guide square tube 3, the two spring rods 9 correspond to the center line of the base plate 1, and the counterweight damping block 10 is located on the outside of the base plate 1, thereby preventing the counterweight damping block 10 from corresponding to the wire, so that the damping force generated by it can be effectively transmitted to the wire, and can also realize the weakening of swing in multiple directions such as up, down, left and right.

[0023] As an optional technical solution of this utility model: the diameter of the inner wall of the pressing support 7 is adapted to the diameter of the top of the inner wall of the upper hook 2, and the inner wall of the pressing support 7 and the inner wall of the upper hook 2 are both fixedly connected with damping anti-slip pads 8. The width of the pressing support 7 is adapted to the distance between the two upper hooks 2. The damping anti-slip pads 8 can improve the firmness of the wire clamping.

[0024] As an optional technical solution of this utility model: the bottom end of the guide rod 4 is rotatably connected to a damping rotating ear 11, the damping rotating ear 11 and the guide rod 4 are damped to rotate, and the middle part of the top surface of the connecting top plate 12 is fixedly connected to the damping rotating ear 11. Through the damping rotation of the damping rotating ear 11, the rotation speed of the connecting top plate 12 and the warning sign 13 can be reduced when they are rotated by wind force, so as to avoid back and forth swaying.
