In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be replaceably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0030] In combination with Figures 1-7 As shown in the drawings, a guardrail comprises a rail plate 3 and a post 1 arranged on both sides of the rail plate 3; the post 1 comprises a column body 11 and a fixed part 12, the column body 11 is provided with a reflective warning part 111, and the fixed part 12 is fixedly connected to one side of the column body 11 close to the rail plate 3; the rail plate 3 comprises a frame 31 and a plurality of vertical rods 32 arranged at intervals, the vertical rods 32 are fixedly connected to the inside of the frame 31, the frame 31 is provided with a hinge assembly 2 on both sides opposite to each column body 11, the hinge assembly 2 comprises two hinge parts 21 arranged at intervals from top to bottom, the fixed part 12 is located between the two hinge parts 21, and each hinge part 21 is hinged to both ends of the fixed part 12.

[0031] When installing the guardrail, for example, Figures 4-5As shown, first, the fixing part 12 is fixed to the column 11 with special angle iron bolts. Then, the guardrail 3 is installed on the fixing part 12 through the hinge assembly 2. The guardrail is adjusted to either a reset state or a rotating state depending on whether the road section where the guardrail is to be placed is straight or curved. In the reset state, the guardrail 3 and the fixing part 12 do not form an angle. Figure 7 As shown, the guardrail 3, the fixing part 12, and the column 11 are in the same straight line position, and the reset state is suitable for straight road sections; as Figure 6 As shown, the rotation state is such that the guardrail 3 and the fixing part 12 rotate to form an angle. For example, both sides of the column 11 are connected to the guardrail 3 through the fixing part 12. Each guardrail 3 forms an angle with the fixing part 12 to adapt to the current curved road section, so that the guardrail fits the curved road section to achieve a warning effect, reduce the occupation of road space, and help improve traffic order. Since the guardrail 3 and the column 1 are connected by a transition, when the guardrail is slightly hit by a vehicle, the vertical bar 32 in the middle of the guardrail 3 deforms to absorb energy; when the guardrail is severely hit by a vehicle, the hinge assembly 2 between the guardrail 3 and the fixing part 12 or the connecting bolt between the fixing part 12 and the column 11 loosens, and the guardrail 3 falls off as a whole; effectively preventing the vertical bar 32 from falling off alone and causing secondary damage to the colliding vehicle.

[0032] The balustrade panel 3 and the post 11 are detachably connected, effectively improving the efficiency of the guardrail's assembly and disassembly. Depending on different usage scenarios, the balustrade panel 3 can be replaced as a whole, for example, with a balustrade panel 3 featuring local urban cultural characteristics, so that the guardrail can serve both a warning and protective function as well as an advertising function.

[0033] When the guardrail of this application is placed on a traffic section where vehicles travel, drivers can observe the oncoming road conditions through the spaced vertical poles 32, while the vertical poles 32 also effectively block oncoming lights.

[0034] In some embodiments, the fixing part 12 includes a fixing block 121 and a fixing member 122. The fixing member 122 protrudes from both ends of the fixing block 121 and is located on the side of the fixing block 121 closest to the column 11. The fixing member 122 is fixedly connected to the fixing block 121. By fixing the fixing member 122 to the column 11, the fixing block 121 is fixedly connected to the column 11. Each of the hinge parts 21 is hinged to both ends of the fixing block 121. This facilitates better layout of the connection position between the guardrail 3 and the column 1, ensuring that the guardrail can smoothly switch between the reset state and the rotation state.

[0035] In some embodiments, the hinge assembly 2 further comprises a hinge shaft 22, which is arranged at the upper and lower ends of the hinge part 21, is fixedly connected to the hinge part 21, and is installed at the two ends of the fixed block 121 to hinge the hinge part 21 to the two ends of the fixed block 121. As shown in the figure, adjusting the included angle between the hinge part 21 and the fixed part 12, i.e. rotating the fence panel 3 to the reset state or the rotating state, is conducive to better adapting the fence panel 3 to the straight line section or the curved line section. At the same time, it is conducive to realizing the modular assembly of the fence and improving the disassembly efficiency. Figures 6-7

[0036] In some embodiments, the cross-sectional shape of the frame 31 is T-shaped. The T-shaped cross-section is conducive to increasing the strength of the frame 31 and preventing deformation, and when the fence is subjected to a collision, it is conducive to realizing the overall shedding of the fence panel 3 and reducing the breakage of the frame 31 to further harm the colliding vehicle or personnel.

[0037] In some embodiments, the plurality of vertical rods 32 are uniformly spaced. The uniformly spaced vertical rods 32 not only can shield the high beam light from the oncoming vehicle, but also can disperse the force when the fence panel 3 is subjected to a collision to prevent the vertical rods 32 from being individually shed or broken to harm the personnel or the vehicle.

[0038] In some embodiments, the vertical rod 32 is a round rod. Artificial cleaning and maintenance of the fence generally uses high-pressure water jet cleaning. Compared with the single cleaning efficiency of 25% of the square vertical rod 32, the single cleaning efficiency of the round rod reaches 50% when cleaning in the same direction, effectively improving the maintenance efficiency. The fence cleaning vehicle can place the rotating roller brush on both sides of the fence, drive the cleaning vehicle, and rotate the roller brush to spray water for cleaning, which can comprehensively clean the round rod.

[0039] In some embodiments, the diameter of the vertical rod 32 is 30 mm, and the spacing between the vertical rods 32 is 110 mm. According to the near-light angle of the driving vehicle, which is generally 25-35°, and the high-light angle, which is generally 5-10°, the vertical rod 32 with a diameter of 30 mm is arranged at a spacing of 110 mm, which is obtained by the inventors after multiple tests and detections, and is suitable for shielding the dazzling light from the oncoming vehicle. At the same time, it also ensures the observation of the opposite road conditions, which is conducive to the normal driving of the vehicle and reduces the occurrence of traffic accidents.

[0040] In some embodiments, the height of the frame 31 is at least 1.1 m. Without affecting the observation of the opposite road conditions by the driver, the fence effectively prevents the high beam when the vehicles are running in opposite directions at a distance of 30-60 m.

[0041] ​In some embodiments, a base 4 is further included, which is fixedly connected to the bottom end of the column 11. Exemplarily, the base 4 is a replaceable base 4, and a movable base 4 or a permanent base 4 can be used according to requirements, which is beneficial to the modular assembly and maintenance of the guardrail.
