[0002] With the rapid development of high-speed rail, my country has built a large number of high-speed railways, bringing great convenience to people's travel. As an efficient and safe means of transportation, railways offer advantages such as high speed, high passenger capacity, strong transportation capacity, and excellent safety. Given the high speeds and strict safety requirements of railways, especially high-speed railways, railway authorities have implemented engineering closures of railway lines by installing protective fences to effectively reduce the security threat posed by people and objects intruding on the lines. However, existing railway line protective fences still have some problems.

[0003] After searching, Chinese patent publication number CN213063172U discloses a high-speed railway protective fence including a base, a column fixedly connected to the middle of the upper surface of the base, a slide groove is provided on the front and back of the column, a slider is slidably connected to the inside of the slide groove, a U-shaped groove is fixedly connected to one side of the slider, and the U-shaped groove is fixedly connected to the guardrail by a first bolt; the guardrail includes a first guardrail and a second guardrail, and the first guardrail and the second guardrail are fixedly connected by a second rotating shaft; the slider cooperates with the second bolt to adjust the height of the guardrail, and the guardrail can be removed for maintenance and replacement by the second bolt.

[0004] However, the above-mentioned protective fence has the following problems during use: if the first guardrail or the second guardrail breaks or is damaged during use, it cannot be replaced separately. The guardrail needs to be removed from the column for repair and replacement, which causes inconvenience in later disassembly and repair;

[0005] When the first and second guardrails of the guardrail are unfolded, a large space will appear at the bottom and middle, allowing people or small animals to enter, which may cause harm to people and animals and pose a safety hazard. Summary of the Invention
