[0026] Furthermore, the buffer assembly includes two pressure plates 8, the outer surfaces of the two pressure plates 8 are respectively slidably connected to the inner walls of the corresponding limiting grooves 6, and one end of the two pressure plates 8 is fixedly connected to a plurality of buffer springs 7, and the ends of the plurality of buffer springs 7 away from the corresponding pressure plates 8 are respectively fixedly connected to the inner walls of the corresponding limiting grooves 6, and the ends of the two pressure plates 8 close to the first protective plate 9 and the second protective plate 10 are respectively in contact with one end of the first protective plate 9 and the second protective plate 10.
[0027] Furthermore, two mounting grooves 11 are opened on one side of the inner wall of the groove 5, and pressure sensors 12 are fixedly connected to the inside of the two mounting grooves 11. One end of the two pressure sensors 12 is fixedly connected to a pressure spring 13, and the two pressure springs 13 are respectively close to one end of the first protective plate 9 and the second protective plate 10 and are in contact with one end of the first protective plate 9 and the second protective plate 10 respectively.
[0028] Furthermore, the two pressure sensors 12 are electrically connected to the automatic alarm light board 3 respectively, the bottom ends of the first protective plate 9 and the second protective plate 10 are fixedly connected with a positioning plate 17, the bottom surface of the inner wall of the groove 5 is provided with a positioning groove 14, and the outer surfaces of the two positioning plates 17 are slidably connected to the inner wall of the positioning groove 14 respectively.

[0030] Furthermore, when the guardrail is hit by an external force, the impact force on the surface of the first guard plate 9 and the second guard plate 10 will be applied to the two pressure plates 8 respectively, and then the two pressure plates 8 will share the impact pressure through multiple buffer springs 7 respectively, so that the first guard plate 9 and the second guard plate 10 can slow down the impact force, which can not only protect the equipment to a certain extent, but also reduce the damage to the guardrail.
[0031] Furthermore, at the same time, when the first protective plate 9 and the second protective plate 10 are hit, the impact force on the surface of the first protective plate 9 and the second protective plate 10 will also be applied to the two pressure springs 13, and then the two pressure springs 13 will also apply pressure to the two pressure sensors 12, thereby causing the two pressure sensors 12 to receive pressure data, which is then transmitted to the automatic alarm light board 3, and then the automatic alarm light board 3 starts to flash the light and alarm the background server.

[0034] Working principle: When the guardrail is hit by external force, the impact force on the surface of the first guard plate 9 and the second guard plate 10 will be applied to the two pressure plates 8 respectively, and then the two pressure plates 8 will share the impact pressure through multiple buffer springs 7, so that the first guard plate 9 and the second guard plate 10 can slow down the impact force, which can not only protect the equipment to a certain extent, but also reduce the damage to the guardrail. At the same time, when the first guard plate 9 and the second guard plate 10 are hit, the impact force on the surface of the first guard plate 9 and the second guard plate 10 will also be applied to the two pressure springs 13, and then the two pressure springs 13 will also apply pressure to the two pressure sensors 12, so that the two pressure sensors 12 are subjected to pressure data, and then transmitted to the automatic alarm light board 3, and then the automatic alarm light board 3 starts to flash lights and alarm the background server. Here, the automatic alarm light board 3 and the pressure sensor 12 are both existing technologies and will not be elaborated here, so that the alarm function can be automatically realized when the guardrail is hit.
