Detailed Description

The following, with reference to the drawings and the detailed description, further description of the present invention is made:

as shown in fig. 1-3, a bridge post collision avoidance device, including bridge and pier post 1, bearing 2 has been cup jointed in the 1 outside of pier post, 2 inner circles of bearing hug closely the installation of pier post 1, the outer lane riveting of bearing 2 is in the inboard of protective layer 3, increase epitaxial antenna 4 on the protective layer 3, antenna 4 is half circular setting towards the channel part along protective layer 3, protective layer 3 and antenna 4 follow when pier post 1 bumps with the ship the outer lane of bearing 2 is rotatory together.

According to the above, the two sides of the antenna 4 are curved. The antenna 4 is set to be in a curve shape, so that the acting force generated when the pier stud 1 collides with a ship can be better converted.

According to the above, the antenna 4 may be disposed in a perpendicular direction to an outer tangent of the protective layer 3.

According to the above, the antenna 4 may rotate clockwise or counterclockwise around the pier stud 1 when the ship collides with the pier stud 1. The feeler 4 can rotate under the deformation force effect of two kinds of hard and soft materials when boats collide with the pier stud 1, because the outer lane of bearing 2 can be followed clockwise or anticlockwise rotation, so feeler 4 also can be around pier stud 1 clockwise or anticlockwise rotation.
