A first slide groove 8 is provided on one side of the main board 2. The buffer mechanism 6 comprises a main guardrail 61 and a secondary guardrail 62. The secondary guardrail 62 is fixedly connected between the fixing plate 4 and the fixing plate 2 5. A connecting hole 63 is provided on the inner side of the secondary guardrail 62.

[0019] In this embodiment, the upper end of the main railing 61 is fixedly connected with a first clamping block 64, the lower end of the fixed plate 1 4 is provided with a second slide groove 9, the first clamping block 64 is slidably connected to the inner side of the second slide groove 9, the lower end of the main railing 61 is fixedly connected with a second clamping block 65, the upper end of the fixed plate 2 5 is provided with a third slide groove 10, the second clamping block 65 is slidably connected to the inner side of the third slide groove 10, and both sides of the main railing 61 are fixedly connected with support ears 66, and the rear ends of the two groups of support ears 66 are fixedly connected to a connecting plate 67 by screws.

[0020] Specifically, when a vehicle has an accident and hits this guardrail, the main guardrail 61 will be impacted first and maintain a certain running trajectory under the restriction of the first block 64 and the second block 65. When the main guardrail 61 is damaged, it can be replaced by simply removing the screws, which is easy to maintain.

[0021] In this embodiment, the rear end of the connecting plate 67 is fixedly connected to the first connecting tube 68, the rear end of the first connecting tube 68 is fixedly connected to the circular plate 69, the first connecting tube 68 and the inner side of the circular plate 69 are slidably connected to the second connecting tube 610, the inner side of the second connecting tube 610 is provided with a first spring 611, the front end of the first spring 611 is fixedly connected to the connecting plate 67, the rear end of the first spring 611 is fixedly connected to the auxiliary railing 62, the rear end of the circular plate 69 is fixedly connected to the limiting rod 612, the limiting rod 612 is movably connected to the inner side of the connecting hole 63, the circular plate 69 and the auxiliary railing 62 are movably connected to the second spring 613, and the second spring 613 is wound around the outer side of the limiting rod 612.

[0022] Specifically, the main guardrail 61 moves backward under the pressure of force, at which time the first spring 611 is squeezed first to cushion the vehicle, and then when the first connecting tube 68 pushes the circular plate 69 to move backward, the second spring 613 is squeezed again to increase the cushioning force again and reduce damage to the vehicle collision.

[0023] In this embodiment, the cleaning mechanism 7 includes a driving gear 71 and multiple groups of auxiliary gears 72. A connecting groove is provided on the inner side of the fixed plate 4. The driving gear 71 and the multiple groups of auxiliary gears 72 are rotatably connected in the connecting groove. A motor 73 is provided on the inner side of the connecting groove. The output end of the motor 73 is fixedly connected to the driving gear 71. The driving gear 71 and the outer sides of the multiple groups of auxiliary gears 72 are meshed with a toothed belt 74. The upper ends of the driving gear 71 and the auxiliary gear 72 are fixedly connected with a rotating rod 75. The upper end of the rotating rod 75 passes through the fixed plate 4 and is fixedly connected with a sweeping rod 76. The lower end of the sweeping rod 76 is provided with a brush 77, and the brush 77 fits with the upper end of the fixed plate 4.

[0024] Specifically, by starting the motor 73, the motor 73 rotates to drive the driving gear 71 to rotate. When the driving gear 71 rotates, the meshing toothed belt 74 causes it to run simultaneously, thereby driving multiple sets of auxiliary gears 72 to operate together. Then, multiple sets of sweeping rods 76 rotate under the drive of the driving gear 71, and the dust on the surface of the fixed plate 4 is cleaned by the brush 77, and the birds are driven away.

[0025] In this embodiment, a threaded rod 21 is fixedly connected to the inner side of the main board 2, and a threaded tube 22 and a column gear 23 are threadedly connected to the outer side of the threaded rod 21. The threaded tube 22 is fixedly connected to the column gear 23, and the threaded tube 22 is adapted to the fixed groove 3. A tooth plate 24 is meshed at the front end of the column gear 23, and a moving rod 25 is fixedly connected to the front end of the tooth plate 24. Both sides of the moving rod 25 are fixedly connected to sliders 26, and the slider 26 is slidably connected to the inner side of the first slide groove 8. A rotating block 27 is rotatably connected to the inner side of the moving rod 25, and the upper end of the rotating block 27 passes through the moving rod 25 and is fixedly connected to a threaded rod 28, and the upper end of the threaded rod 28 passes through the main board 2 and is fixedly connected to a rotating button 29, and the threaded rod 28 is threadedly connected to the main board 2.

[0026] Specifically, by turning the knob 29 with a wrench, the threaded rod 28 is connected to make it descend. During the descent, the movable rod 25 is pushed to drive the toothed plate 24 to move downward at the same time, and the movable rod 25 will not rotate with the threaded rod 28 under the connection of the rotating block 27. However, the toothed plate 24 moves downward while engaging the column gear 23 to rotate. Since the column gear 23 is threadedly connected to the threaded rod 1 21, the threaded tube 22 is moved from the inner side of the main board 2 2 to the inner side of the fixed groove 3 as the thread rotates. At this time, the first group and the second group of guardrails are tightly connected.

[0027] During operation, multiple groups of the guardrails are arranged in sequence on both sides of a highway or bridge for installation. The main plate 22 in the first group of guardrails is placed close to the main plate 1 in the second group of guardrails, and the knob 29 is turned with a wrench to lower it under the connection of the threaded rod 28. During the lowering process, the moving rod 25 is pushed to drive the toothed plate 24 to move downward at the same time, and under the connection of the rotating block 27, the moving rod 25 will not rotate with the threaded rod 28. However, the toothed plate 24 engages the column gear 23 to rotate while moving downward. Since the column gear 23 is threadedly connected to the threaded rod 1 21, the threaded tube 22 is moved from the inner side of the main plate 22 to the inner side of the fixed groove 3 as the thread rotates. At this time, the first and second groups of guardrails are closely connected. When a vehicle has an accident and hits this guardrail, the main guardrail 61 will be impacted first, and the first block 64 and the second block 64 will be impacted first. 65, maintains a certain running trajectory, and then the main fence 61 moves backward under the pressure of force. At this time, the first spring 611 is squeezed first to buffer the vehicle. Then, when the first connecting tube 68 pushes the circular plate 69 to move backward, the second spring 613 is squeezed again, and the buffering force is increased again to reduce the damage caused by the vehicle collision. In addition, when the guardrail is used in daily life, in order to clean the dust and drive away the birds in time, the motor 73 needs to be started. The rotation of the motor 73 drives the driving gear 71 to rotate. When the driving gear 71 rotates, it is meshed with the toothed belt 74 to make it run at the same time, thereby driving multiple groups of auxiliary gears 72 to operate together. Then, multiple groups of sweeping rods 76 rotate under the drive of the driving gear 71, and the dust on the surface of the fixed plate 4 is cleaned by the brush 77, and the birds are driven away to prevent them from docking.
