Bridge anti-collision system capable of resisting ship collision

The invention discloses a ship-collision-resistant bridge anti-collision system which comprises an anti-collision structure arranged on the upstream portion and an anti-collision structure arranged on the downstream portion in the transverse bridge direction, the two anti-collision structures are symmetrically arranged with a main bridge bearing platform of a bridge as the center and connected with the main bridge bearing platform through force transmission pieces, and the anti-collision structures can prevent ships from colliding with the main bridge bearing platform and can also prevent the ships from colliding with the main bridge bearing platform. The anti-collision structure is connected with the main bridge bearing platform, so that the main bridge bearing platform participates in cooperative stress when the anti-collision structure is collided and bears ship collision force together; the anti-collision structure is provided with a large rotary drum, the large rotary drum rotates when the ship collides,
