[0027] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-4A bridge guardrail snow-clearing device shown includes a connecting structure, an adjusting lever arm 10 is installed on the connecting structure, the adjusting lever arm 10 can perform lifting movement, the connecting structure is connected to the carrier through the adjusting lever arm 10, a snow scraping mechanism is installed on the connecting structure, the connecting structure includes a connecting plate 9 and a transverse plate 11, the side wall of the transverse plate 11 is fixedly connected to the side wall of the connecting plate 9, the adjusting lever arm 10 is connected to the connecting plate 9, and the snow scraping adjusting lever arm 10 can indirectly adjust the height of the snow scraping mechanism through the connecting plate 9 so that its bottom can contact the bridge surface;

[0029] The utility model snow scraping mechanism comprises an obstacle avoidance component and a scraper 4, the obstacle avoidance component is mounted on the transverse plate 11, a part of the obstacle avoidance component can be extended from the side of the bridge when working, the part that can be extended from the side of the bridge is equipped with a rotating component that rotates clockwise, the rotating component is connected to one end of the scraper 4, the upper end surface of the scraper 4 can slide with the lower end surfaces of the transverse plate 11 and the connecting plate 9, the lower end surfaces of the transverse plate 11 and the connecting plate 9 are both equipped with a plurality of running wheels 12, the bottom of the running wheel 12 and the lower end surface of the scraper 4 are on the same horizontal plane, the running wheel 12 plays a certain auxiliary supporting role on the transverse plate 11 and the connecting plate 9.

[0030] Specifically, when the end of the scraper 4 away from the rotating assembly just slides out from under the horizontal plate 11, the rotating assembly controls the scraper 4 to stop rotating, and a certain angle is formed between the scraper 4 and the side of the bridge. As the vehicle moves, the snow is pushed to the end of the scraper 4 extending outside the bridge, and then falls off the bridge. When the obstacle avoidance plate 6 is a certain distance away from the column 1, the rotating assembly drives the scraper 4 to rotate again, pushing the snow around the column 1 off the bridge, achieving rapid removal of snow around the anti-collision guardrail, and improving work efficiency.

[0031] A stopper 3 is slidably mounted on one end of the scraper 4 away from the rotating component, and an elastic component is connected to the lower end of the stopper 3. The elastic component includes a spring 13 and a fixed plate 14. The fixed plate 14 is fixed on the scraper 4, and the fixed plate 14 is located below the stopper 3. One end of the spring 13 is connected to the stopper 3, and the other end of the spring 13 is connected to the fixed plate 14. A downwardly inclined inclined surface 15 is provided on the upper end of the stopper 3, and the inclined surface 15 can slide with the side wall of the connecting plate 9.

[0032] Specifically, during the rotation of the scraper 4, the block 3 at its end is driven to rotate together. The block 3 is extended from the upper end of the scraper 4 under the support of the spring 13. During the clockwise rotation of the scraper 4, the inclined surface 15 at the upper end of the block 3 contacts the side of the connecting plate 9. As the scraper 4 rotates continuously, the block 3 gradually moves downward relative to the scraper 4 and gradually compresses the spring 13. When the scraper 4 is drawn out from the lower end surface of the horizontal plate 11, the block 3 pops out from the upper end surface of the scraper 4, and the reset block 3 can be against the side wall of the horizontal plate 11.

[0033] Specifically, the rotating assembly includes a rotating motor 5 and an anti-reversal structure. The rotating motor 5 is installed on the obstacle avoidance assembly, the anti-reversal structure is installed on the rotating motor 5, and the scraper 4 is connected to the rotating motor 5. Under the joint action of the block 3 and the anti-reversal structure, the scraper 4 can be effectively prevented from rotating counterclockwise when scraping snow, affecting the snow removal effect.

[0034] The obstacle avoidance component of the utility model includes a swing motor 8 and an obstacle avoidance plate 6, a rotating motor 5 is installed on the obstacle avoidance plate 6, the obstacle avoidance plate 6 is rotatably installed at one end of the horizontal plate 11, the swing motor 8 is installed on the horizontal plate 11, and the end of the swing motor 8 is connected to the obstacle avoidance plate 6. The swing motor 8 can drive the obstacle avoidance plate 6 to rotate to a state perpendicular to or parallel to the horizontal plate 11. The obstacle avoidance plate 6 is always located on the side where the connecting plate 9 is connected to the horizontal plate 11. A distance sensor 2 is installed on the obstacle avoidance plate 6, and a controller is installed on the connecting plate 9. The distance sensor 2, the swing motor 8 and the rotating motor 5 are all electrically connected to the controller.

[0035] Specifically, a limit plate 7 is installed on the transverse plate 11. When the obstacle avoidance plate 6 rotates to a state perpendicular to the transverse plate 11, the limit plate 7 can contact the side wall of the obstacle avoidance plate 6. The height of the connecting plate 9 is greater than the height of the transverse plate 11. The side wall of the connecting plate 9 can limit the rotation of the obstacle avoidance plate 6. Both of them limit the rotation of the obstacle avoidance plate 6 at the same time, so that the obstacle avoidance plate 6 always reciprocates within a 90° range on the side of the connecting plate 9 close to the transverse plate 11.

[0036] Specifically, when the distance sensor 2 detects that the obstacle avoidance plate 6 is at a certain distance from the column 1, it will feed back the position signal to the controller, and the controller controls the rotary motor 5 to drive the scraper 4 to rotate clockwise to push all the snow off the side of the bridge. After the snow around the column 1 is cleared, the scraper 4 continues to rotate until its vertical symmetry plane coincides with the vertical symmetry plane of the obstacle avoidance plate 6, and then the rotary motor 5 controls the scraper 4 to stop rotating;

[0037] When the distance sensor 2 detects that the column 1 is about to contact the obstacle avoidance plate 6, the position signal is fed back to the controller, and the controller controls the swing motor 8 to turn on, and the swing motor 8 drives the obstacle avoidance plate 6 to rotate clockwise. When the obstacle avoidance plate 6 contacts the connecting plate 9, the swing motor 8 stops rotating. When avoiding obstacles, the scraper 4 always keeps the state of overlapping with the obstacle avoidance plate 6 to avoid the scraper 4 from interfering with the movement of the device when passing the column 1. After the vehicle carries the device forward for a distance, the swing motor 8 drives the obstacle avoidance plate 6 to rotate counterclockwise to the limit plate 7, and the rotating motor 5 drives the scraper 4 to rotate and reset, so that automatic obstacle avoidance can be achieved while scraping snow.
