[0002] With the development of the electric power industry and urban and rural road construction, the number of power supply stations has increased year by year, and the number of high-voltage electric shock accidents in crowded areas has also increased. This is mainly because illegal ultra-high operations, fishing and other activities are carried out under the lines, resulting in power accidents such as grounding, short circuits and broken lines, which seriously affect the safe operation of the lines and cause huge economic losses to the power sector. Therefore, most of the existing high-voltage lines will be installed around corresponding safety warning devices to warn people approaching.

[0003] Publication number "CN217870133U" provides a warning device for high-voltage cables. The user installs a ground stake near the high-voltage cable and then pulls the warning plate upward. The upward movement of the warning plate drives the slide plate and the threaded sleeve to move synchronously, solving the problem that the existing warning equipment does not have the reflective height adjustment function and increasing the safety of the warning equipment.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the warning device has the ability to adjust the height, it cannot effectively warn approaching personnel by relying solely on a single warning plate. Although some warning devices in the prior art have the ability to provide sound and light alarms when people approach, the supporting structure of the warning device mostly uses a single supporting column for support, which causes the device to shake and tilt easily when encountering strong winds outdoors, and its stability in use needs to be improved.
