[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: A power cable identification device includes a bearing seat 1. The inner walls of the upper end and the lower end of the bearing seat 1 are both concave. The bearing seat 1 provides support for the indicator board 2. A cylindrical hole is provided on the inner wall of the upper end of the bearing seat 1. A sliding groove 5 is provided on the inner wall of the front end of the bearing seat 1. The sliding groove 5 provides support and guidance for the sliding of the fixed column 6. The sliding groove 5 is in a C shape, and there are two sliding grooves 5 which are axially symmetrically arranged. Through holes 4 are provided on the inner wall of the front end of the bearing seat 1, and the through holes 4 are evenly distributed on the inner wall of the bearing seat 1. An extension ring 3 is slidably connected to the side wall of the bearing seat 1. Horizontally, the extension ring 3 rotates on the side wall of the bearing seat 1 as the fixed column 6 slides on the inner wall of the sliding groove 5. Vertically, the extension ring 3 slides on the side wall of the bearing seat 1 as the fixed column 6 slides on the inner wall of the sliding groove 5. A fixed column 6 is fixedly connected to the inner wall of the extension ring 3. The fixed column 6 drives the extension ring 3 to move as it slides on the inner wall of the sliding groove 5. The outer wall of the fixed column 6 penetrates and is slidably connected to the inner wall of the sliding groove 5. An indicating component is provided on the inner wall of the upper end of the bearing seat 1, and the indicating component is used to indicate the direction. A limiting component is provided on the inner wall of the upper end of the bearing seat 1, and the limiting component is used for fixation.

[0032] Reference Figure 1 、 Figure 2 and Figure 4 , the indicating assembly includes an indicating board 2 which functions as an indicator. The indicating board 2 can be replaced with an indicating board 2 in a corresponding indicating direction according to the indication requirement. The outer wall of the indicating board 2 is slidably connected to the upper inner wall of the bearing seat 1. A column 9 is fixedly connected to the outer wall at the bottom end of the bearing seat 1. When the left outer wall of the insert panel 7 is clamped to the right inner wall of the column 9, the indicating board 2 can be fixed by fixing the column 9. A through groove is provided in the inner wall of the column 9.

[0033] Refer to Figure Figure 3 , the limiting assembly includes an insert panel 7. When selecting an indicating board 2 in a corresponding direction, by pressing the indicating board 2 and the column 9 from the upper end of the bearing seat 1 towards the upper inner wall of the bearing seat 1, the outer wall at the bottom end of the column 9 presses the left upper inclined surface of the insert panel 7. The insert panel 7 is pressed and moves to the right, squeezing the spring 8. As the indicating board 2 and the column 9 continue to move downward, when the outer wall at the bottom end of the column 9 contacts the bottom end of the upper inner wall of the bearing seat 1, the insert panel 7 pops out to the left and is clamped to the right inner wall of the column 9. The indicating board 2 is fixed by fixing the column 9. The outer wall of the insert panel 7 is slidably connected to the upper inner wall of the bearing seat 1. The left upper outer wall of the insert panel 7 is inclined. The left outer wall of the insert panel 7 is clamped to the right inner wall of the column 9. The right outer wall of the insert panel 7 is elastically connected to the upper inner wall of the bearing seat 1 through a spring 8. One end of the spring 8 is fixedly connected to the right outer wall of the insert panel 7, and the other end of the spring 8 is fixedly connected to the upper inner wall of the bearing seat 1.

[0034] Working principle: After selecting an indicating board 2 in a corresponding direction, press the indicating board 2 and the column 9 from the upper end of the bearing seat 1 towards the upper inner wall of the bearing seat 1. At this time, the outer wall at the bottom end of the column 9 presses the left upper inclined surface of the insert panel 7. Since the left upper outer wall of the insert panel 7 is inclined, the insert panel 7 will move to the right after being pressed and squeeze the spring 8. As the indicating board 2 and the column 9 continue to move downward, when the outer wall at the bottom end of the column 9 contacts the bottom end of the upper inner wall of the bearing seat 1, the insert panel 7 loses the extrusion effect of the column 9 and pops out to the left under the elastic restoring force of the spring 8 and is clamped to the right inner wall of the column 9. In this way, the column 9 is fixed, and then the indicating board 2 is fixed to ensure that the indicating board 2 will not loosen or shift during use. Subsequently, rotate the extension ring 3 clockwise, then move the extension ring 3 downward and then rotate it counterclockwise to extend the marking device to complete the assembly of the marking device. When installing, dig a marking installation pit on the road surface above the cable, pour cement into the pit, and then press the marking device into the cement. At the same time, pour cement into the interior and the side of the marking device through the through hole 4 to ensure that the upper outer wall of the indicating board 2 of the marking device is flush with the road surface.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
