[0029] See also Figure 1-4 A bridge pier anti-collision device comprises an anti-collision unit 1 arranged on the front and rear sides of a bridge pier body 1 and an anti-collision unit 2 arranged on the left and right sides of the bridge pier body 1; the anti-collision unit 1 comprises an anti-collision frame 2 and a connecting plate 6 fixed on both sides of the anti-collision frame 2, the anti-collision unit 2 comprises an anti-collision frame 3 and a connecting plate 27 fixed on both sides of the anti-collision frame 23, the anti-collision frames 2 on the front and rear sides are respectively connected to the connecting plates 27 on both sides of the two anti-collision frames 23 on the left and right sides through the connecting plates 6 on both sides; a plurality of spring steel plates 4 are fixed on the front and rear sides of the anti-collision frame 2 and the anti-collision frame 23, and the spring steel plates 4 on one side are slidably fitted on the bridge

[0030] On the pier body 1, the spring steel plates 14 on both sides of the anti-collision frame 1 2 and the anti-collision frame 2 3 can play the role of initial buffering against impact. The spring steel plate 14 on one side contacts the ship, and the spring steel plate 14 on the other side contacts the surface of the pier body 1.

Both ends of the fixed cylinder 1 901 are movably penetrated by a telescopic rod 8, and one end of each telescopic rod 8 is movably penetrated into the fixed cylinder 2 902 and fixed with a piston 17, and the piston 17 slides in the fixed cylinder 2 902, and each telescopic rod 8 The other end of the movable body passes through the anti-collision frame 2 or the anti-collision frame 3 and is fixedly connected to the corresponding spring steel plate 4; two fixed plates 15 are symmetrically fixed on the inner wall of the fixed cylinder 901, and a buffer spring 16 sleeved on a telescopic rod 8 is fixed on one side of each fixed plate 15.

[0033] Specifically, after the air enters the fixed cylinder three 903, it can squeeze the piston two 19 to move, and use the piston two 19 to drive the buffer spring two 21 to compress, and at the same time push the movable rod 20 to squeeze the spring steel plate two 22, thereby achieving further buffering and weakening of the impact force in the fixed cylinder three 903, which can provide better protection for the pier body 1.

[0034] In this embodiment, a fixing rod 11 is fixed at the center of the bottom of the anti-collision frame 1 2 and the anti-collision frame 2 3, a chain 12 is connected to the bottom of the fixing rod 11, and a counterweight 13 is connected to the bottom of the chain 12. Figure 2 As shown, the counterweight 13 is made of stainless steel.

[0035] Specifically, by arranging chains 12 and counterweights 13 at the bottom of the anti-collision frame 1 2 and the anti-collision frame 2 3, the center of gravity of the anti-collision frame 1 2 and the anti-collision frame 2 3 can be stabilized, so that the anti-collision frame 1 2 and the anti-collision frame 2 3 can float on the water more stably.

[0036] In this embodiment, if Figure 3 As shown, a docking groove 601 is equidistantly provided on the side of the connecting plate 6 away from the anti-collision frame 2, and a docking block 701 adapted to the docking groove 601 is equidistantly fixed on the side of the connecting plate 2 7 away from the anti-collision frame 2 3, and the two sides of the anti-collision frame 2 are bolted to the docking blocks 701 on both sides of the anti-collision frame 2 3 through the docking groove 601.

[0038] During installation, two anti-collision frames 1 2 are placed on the front and rear sides of the pier body 1, and two anti-collision frames 2 3 are placed on the left and right sides of the pier body 1, and the docking blocks 701 are inserted into the corresponding docking grooves 601 and fastened with bolts. At this time, the anti-collision device is installed and floats on the water surface;

[0039] When the front and rear sides of the anti-collision device are hit by a ship, the anti-collision unit-structure is set: the spring steel plate-4 on the anti-collision frame-2 can be impacted first, the spring steel plate-4 bends and weakens part of the impact force, and the bending of the spring steel plate-4 can push the telescopic rod 8, and the telescopic rod 8 pushes the buffer spring-16 through the movable plate 14 to compress and weaken the impact force again. When the telescopic rod 8 moves, it can synchronously push the piston-17 to move toward the middle of the inner cavity of the fixed cylinder-2 902 and squeeze the air, and the air enters the fixed cylinder-2 902. The fixed cylinder 3 903 pushes the piston 2 19 to compress the buffer spring 2 21, and uses the movable rod 20 to squeeze the spring steel plate 2 22. The deformation of the spring steel plate 22 is used to weaken the impact force again, thereby achieving a multi-layer buffering and weakening effect on the impact force, which can better protect the pier body 1 and reduce the possibility of damage to the pier body 1. Similarly, when the left and right sides of the pier body 1 are hit, the anti-collision unit 2 structure: the anti-collision frame 2 3 can achieve the same protection effect on the left and right sides of the pier body 1 as mentioned above.
