[0038] Reference Figure 1 and Figure 3, the outer walls of the multiple expansion bolts 14 are provided with anti-skid grooves 17, which are used to increase the friction between the expansion bolts 14 and the ground or the installation foundation to prevent loosening. The multiple anti-skid grooves 17 are staggered and connected to each other to further improve the anti-skid effect. The bottom walls of the two bases 13 are designed with an anti-skid design to enhance the friction between the base 13 and the ground and improve stability. The two bases 13 are both small on the top and large on the bottom, which increases the stability of the base 13, lowers the center of gravity and prevents tipping. The multiple threaded connecting rods 5 on the far side can be threadedly connected to the additional extended fixed sleeve 6, which is convenient for the guardrail to be expanded and connected to meet different length requirements;

[0039] Specifically, the openings on the outer wall of the expansion bolts 14 and the interlaced connection with each other increase the friction between the expansion bolts 14 and the ground or the installation foundation, preventing the expansion bolts 14 from loosening during use. The anti-slip design of the bottom wall increases the friction between the base 13 and the ground, making the guardrail more stable when placed and not easy to slide. The shape of small at the top and large at the bottom increases the stability of the base 13, lowers the center of gravity of the guardrail, and improves the anti-dumping ability. The threaded connecting rod 5 on the far side can be threadedly connected to the additional extended fixed sleeve 6, which makes the guardrail scalable and can connect more guardrail units according to actual needs to meet the needs of municipal roads of different lengths.

[0040] Working principle: During the assembly process, by connecting the limiting rod 4 on the column 1 and the beam 3 with the fixed sleeve 6, the threaded connecting rod 5 on the limiting rod 4 cooperates with the threaded groove 8 in the middle of the inner wall of the fixed sleeve 6. When the threaded connecting rod 5 is screwed into the threaded groove 8, the initial connection and fixation are achieved. At the same time, the limiting rod 4 and the limiting groove 7 on the outer side of the inner wall of the fixed sleeve 6 engage with each other, ensuring the accuracy and stability of the connection and preventing deviation during the connection process. When the threaded connecting rod 5 is fully screwed into the threaded groove 8, the upper and lower ends of the limiting rod 4 are aligned with the fixing grooves 9 at the upper and lower ends of the fixing sleeve 6. At this time, the fixing bolt 10 is screwed into the fixing groove 9, further strengthening the firmness of the connection, the round head nut 11 on the top of the fixing bolt 10 prevents the fixing bolt 10 from loosening and falling off. After the main structure of the guardrail is connected, the multiple reinforcing rods 12 equidistantly fixedly connected between the two crossbeams 3 enhance the overall strength and impact resistance of the guardrail, which can effectively prevent the guardrail from being deformed or damaged by external impact, thereby improving the safety and reliability of the guardrail. The base 13 at the bottom of the two columns 1 provides a stable support for the entire guardrail. The base 13 increases the contact area with the ground, so that the guardrail can stand firmly on the municipal road during use and is not easy to tip over.

[0041] In addition, multiple solar panels 201 are equidistantly fixedly connected around the outer wall of the left column 1, which fully receive solar energy during the day and convert it into electrical energy. The solar panels 201 are electrically connected to the battery 202 on the inner wall of the left column 1, and the converted electrical energy is stored in the battery 202. When night falls or there is insufficient light, the battery 202 begins to work. The mounting plate 203 at the top of the left column 1 provides a stable mounting position for the lamp holder 204. The flash panels 205 on the front and rear sides and the left and right sides of the lamp holder 204 are electrically connected to the battery 202. At this time, the battery 202 supplies power to the flash panel 205, and the flash panel 205 begins to emit light. The light emitted by the flash panel 205 can improve the visibility of municipal roads at night and provide safety warnings for pedestrians and vehicles.
