[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Reference Figure 1-4 A bridge pier anti-ship collision device includes two arcuate pier seats 1 and a plurality of square pier seats 2. The arcuate pier seats 1 are distributed at both ends, and the square pier seats 2 are arranged between the two arcuate pier seats 1. The square pier seats 2 are connected to the arcuate pier seats 1 through a connecting structure a, and the square pier seats 2 are connected through a connecting structure b. The outer sides of the arcuate pier seats 1 and the square pier seats 2 can be detachably connected with anti-collision structures.
[0019] The arcuate pier seat 1 and the square pier seat 2 are assembled around the pier and fixed by connecting bolts a7 and connecting bolts c, and then the arcuate anti-collision block 3 and the straight anti-collision block 11 are installed on the arcuate pier seat 1 and the square pier seat 2 respectively to play a primary anti-collision role. The arcuate pier seat 1 and the square pier seat 2 are secondary anti-collision structures. Due to their replaceability, the maintenance cost is reduced. For circular piers, two arcuate pier seats 1 can be directly assembled, and for elliptical piers, the number of square pier seats 2 can be appropriately increased or decreased according to the length of the pier. The remaining gap can be stretched and fixed by connecting bolts a7. It has wide applicability and simple maintenance.
[0020] In this embodiment, the anti-collision structure includes an arc-shaped anti-collision block 3 connected to the arc-shaped pier seat 1 and a straight anti-collision block 11 connected to the square pier seat 2. Both ends of the outer sides of the straight anti-collision block 11 and the arc-shaped anti-collision block 3 are provided with sunken steps 4, and bolt holes a5 are provided on the sunken steps 4. Connecting bolts b are provided in the bolt holes a5. The connecting bolts b are threadedly connected to the arc-shaped pier seat 1 and the square pier seat 2, respectively. Due to its replaceability, the maintenance cost is reduced.
[0021] In this embodiment, the connecting structure a includes a cutting surface 6 arranged at the end of the arc-shaped pier seat 1, and the side wall of the cutting surface 6 is connected to a connecting ear a8, the outer side of the connecting ear a8 is flush with the outer side surface of the square pier seat 2, and a bolt hole b9 is arranged on the connecting ear a8, and a connecting bolt c is arranged in the bolt hole b9, and the connecting bolt c is threadedly connected to the square pier seat 2.
[0022] In this embodiment, the connection structure b includes connection ears b10 arranged on the upper and lower end sides of the square pier 2, and the connection ears b10 are connected by connecting bolts a7.
[0023] The arc-shaped pier seat 1 and the square pier seat 2 are both hollow structures. When the arc-shaped pier seat 1 and the square pier seat 2 are assembled, a proper gap can be left to avoid interference between the arc-shaped pier seat 1 and the square pier seat 2 when they move up and down in water due to buoyancy.
[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
