Detailed Description
The utility model is further described in the following with specific embodiments in conjunction with the accompanying drawings, see fig. 1-5:
example 1:
the utility model provides a crash barrier which characterized in that: the method comprises the following steps:
a guardrail support;
a rotating shaft 1;
the protective cylinder 2, the protective cylinder 2 is set up on the rotating shaft 1;
the water storage cylinders 11 are of fan-shaped structures and are arranged between the rotating shaft 1 and the protective cylinder 2;
wherein, the guardrail support includes many pole settings 3 and is located the horizontal pole 4 at 3 upper and lower both ends of pole setting, connects through horizontal pole 4 between many pole settings 3, and 1 covers of rotation axis are located on pole setting 3.
The guardrail support can be made of metal, the supporting strength is high, and the anti-collision buffer effect can be achieved through the arrangement of the protective cylinder 2; the water storage cylinder 11, the protective cylinder 2 and the rotating shaft 1 can be arranged in a clearance mode, so that the rotating shaft 1 is prevented from being blocked in rotation, the anti-collision and energy-absorbing effects can be further achieved through the arrangement of the water storage cylinder 11, and the buffering effect is better; the protective cylinder 2 can freely rotate around the rotating shaft 1 or the rotating shaft 1 rotates around the upright rod 3, namely, when the protective cylinder 2 is impacted, the protective cylinder 2 can also rotate to play a certain role in energy absorption and buffering; the water storage cylinder 11 is in a fan-shaped structure and is easier to place or take out, and in order to facilitate taking out, the top surface of the water storage cylinder 11 can be provided with a pull ring.
Further comprising:
