Description

Technical Field

[0001] The invention relates to the field of bridge anti-collision, and in particular to a bridge anti-collision device. Background Art

[0002] A bridge is a structure used to cross obstacles (such as rivers, valleys, roads or other waters), among which bridges across rivers, rivers or seas are the most common. At the same time, with the development of the economy, the size, tonnage and density of ships crossing bridges have increased significantly, and the speed of ships has also increased significantly. During the sailing process of ships, due to water flow, hull failure or operator error, accidents of large-tonnage, large-size and high-speed ships hitting bridges occur frequently, which may cause bridges to break and people to fall into the water in serious cases, seriously threatening people's safety.

[0003] In order to solve the above problems, the prior art generally provides the following anti-collision devices on bridge piers:

[0004] CN207904832U discloses a splicing structure of a composite material bridge anti-collision device, which includes an upper connecting section formed at the end of the anti-collision unit and a lower connecting section formed at the end of the anti-collision unit. The lower connecting section and the upper connecting section form a complete cylindrical structure after splicing, and the lower connecting section and the upper connecting section are connected by bolts inserted from the lower connecting section to the upper connecting section.

[0005] CN207904753U discloses an anti-collision unit structure of a composite material bridge pier anti-collision device, including a cylinder, in which a cylindrical steel skeleton structure is arranged, the steel skeleton structure and the cylinder are connected by a plurality of anti-collision beams uniformly distributed along the circumferential direction, and a polymer closed-cell foam material core is filled between two adjacent anti-collision beams; the steel skeleton structure, the polymer closed-cell foam material core and the plurality of anti-collision beams form a cylindrical structure cavity, and the cylindrical structure cavity is filled with lightweight friction particles.

[0006] It can be seen that the existing bridge anti-collision structures mostly use elastic materials to cushion the impact of the hull.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1-Figure 5 As shown, a bridge anti-collision device includes an inner elastic buffer component 3, an intermediate impact buffer component and an outer guide buffer component 5 which are sequentially arranged on the outer side of a bridge pier 1 from the inside to the outside, wherein the intermediate impact buffer component includes a plurality of impact buffer units evenly arranged in a circular array, each impact buffer unit includes a water bag compartment 2 and an air bag compartment 6 arranged below the water bag compartment 2, an impact margin is left between the water bag compartment 2 and the air bag compartment 6, and the water bag compartment 2 is connected to one end of a water outlet resistance pipe 32, and the other end of the water outlet resistance pipe 32 extends below the horizontal plane; the end of the water outlet resistance pipe 32 extending below the water surface and facing the bridge pier 1 is provided with a water outlet.

[0039] Specifically, the water outlet resistance pipe 32 includes a plurality of water blocking pipe sections arranged in sequence along the direction of the water bag cabin 2 toward the water surface, and the plurality of water blocking pipe sections are connected in sequence; the water blocking pipe section includes an ear-shaped water blocking pipe 321 and a straight water flow pipe 322, the water inlet end of the ear-shaped water blocking pipe 321 coincides with the water inlet end of the straight water flow pipe 322, and the water outlet end of the ear-shaped water blocking pipe 321 bends toward the water outlet end of the straight water flow pipe 322; the water outlet end of the previous water blocking pipe section coincides with the water inlet end of the next water blocking pipe section. The ear-shaped structures of the ear-shaped water blocking pipes 321 of two adjacent water blocking pipe sections are arranged relative to each other. A counterweight sealing cylinder 33 is threadedly connected to the water outlet resistance pipe 32 extending into the water surface, and a sealing film is sealedly connected to the inner wall of the counterweight sealing cylinder 33. By setting the counterweight sealing cylinder 33, the water outlet of the water outlet resistance pipe 32 can be kept underwater while facilitating the replacement of the sealing film, so as to facilitate the dispersion of the impact underwater.

[0040] The above structure realizes that when the ship collides with the outer guide buffer assembly 5 and the impact force is transmitted to the water bag cabin 2, the water bag cabin 2 is squeezed, so that the water pressure in the water bag cabin 2 increases, and the water flows out along the water outlet resistance pipe 32, breaks the sealing film and is discharged into the water. Since the drainage direction is toward the direction of the pier 1, the water bag cabin 2 can be pushed in the reverse direction by the water flow to play a buffering role. At the same time, when the water flows in the water outlet resistance pipe 32, each section of the ear-shaped water blocking pipe 321 will block the water outflow of the straight water flow pipe 322, thereby further buffering the impact of the ship with the help of the water flow resistance.

[0041] The water bag compartment 2 is placed in an elastic limit frame 4, which is a frame structure composed of elastic connecting ropes and opened at the top and bottom. The two ends of the elastic ropes are flexibly connected to the inner elastic buffer component 3 and the outer guide buffer component 5 respectively; the air bag compartment 6 is placed at the bottom end of the water bag compartment 2 and is located on the outside of the elastic limit frame 4. The top of the air bag compartment 6 is connected to the bottom end of the water bag compartment 2 through an elastic connecting rope. A plurality of cross-shaped resistance plates arranged in an array are fixed to the bottom end of the air bag compartment 6. The cross-shaped resistance plate 61 is made of plastic, and a counterweight is fixed to the bottom end of the cross-shaped resistance plate 61. The water bag compartment 2 is deformed by impact, which drives the air bag compartment 6 to shift, thereby driving the cross-shaped resistance plate 61 to shift. During the shift, the cross-shaped resistance plate 61 is subjected to the resistance of water, thereby using the resistance of water to buffer the impact of the ship.

[0042] The inner elastic buffer assembly 3 includes a rigid mounting plate fixed to the outer side of the bridge pier 1 by expansion bolts and an elastic rubber pad bonded to the rigid mounting plate. The elastic rubber pad has a limited opening on one side facing the water bag compartment 2. One end of the water bag compartment 2 is placed in the limited opening, and a buffer gap is left between the water bag compartment 2 and the inner wall of the limited opening. By setting the buffer gap, the impact force of the ship can be further prevented from being transmitted to the pier 1.

[0043] The outer guide buffer assembly 5 includes a top positioning ring and a bottom positioning ring arranged concentrically with the bridge pier 1, and a plurality of guide buffer cylinders 52 arranged between the top positioning ring and the bottom positioning ring in a circular array and evenly rotated vertically. The bottom positioning ring of this embodiment is placed at the top of the airbag cabin 6, and the capacity of the airbag cabin 6 is greater than the inflation volume, so as to avoid it from exploding after being hit. The two ends of the guide buffer cylinder 52 are respectively connected to the top positioning ring and the bottom positioning ring vertically and rotatably via a rotating shaft 53 and a torsion spring 54; the guide buffer cylinder 52 is made of polymer plastic. The outer side of the top positioning ring and the bottom positioning ring are both composed of multiple arc segments 51, and the adjacent arc segments 51 are connected vertically and rotatably via a rotating shaft 53 and a torsion spring 54. Each arc segment 51 is sleeved with an anti-collision buffer sleeve, which is made of sponge material. The above structure can realize the following buffering when a ship collides with the outer guide buffer assembly 5: the elasticity of the guide buffer cylinder 52 and the anti-collision buffer sleeve can be used to buffer the impact force, and the ship contacts the guide buffer cylinder 52 to drive the guide buffer cylinder 52 to rotate, thereby driving the torsion spring 54, thereby buffering the impact force with the elasticity of the torsion spring 54; and the guide buffer cylinder 52 can also be used to guide the ship tangentially to prevent the ship from continuing to collide with the bridge pier 1. At the same time, the setting of the torsion spring 54 is also convenient for resetting after the ship collision.

[0044] A water injection port 31 is provided at the top of the water bag cabin 2, and a sealing cover is threadedly connected to the water injection port 31. When the water bag cabin 2 is hit and the sealing film is damaged, a new sealing film can be replaced and water can be injected into the water bag cabin 2 for reuse.

[0045] Working principle: When a ship hits the pier 1 in a certain direction, the ship first contacts the outer guide buffer assembly 5, and while the ship is guided to move tangentially with the help of the guide buffer cylinder 52, the elasticity of the guide buffer cylinder 52 and the torsion spring 54 is used to perform primary buffering of the impact force; the arc segment 51 is deformed and transmits the impact force to the water bag compartment 2. After the water bag compartment 2 is squeezed, the water flow breaks through the sealing membrane and is discharged in the direction of the pier 1, and the drainage and water flow resistance in the water outlet resistance pipe 32 are used for secondary buffering (the secondary buffering also includes the use of water to the cross-shaped resistance plate 61 during the movement); when the water bag compartment 2 hits the elastic rubber pad, the elastic rubber pad is used for tertiary buffering, thereby achieving the dispersion of the impact force with the help of the tertiary buffer and transmitting it to the water, thereby effectively protecting the pier 1.

[0046] Therefore, the present invention adopts the bridge anti-collision device of the above structure, which is equipped with a three-level buffer structure to disperse the impact force of the ship into the water. It cooperates with the outer guide buffer component to guide the ship to move tangentially while buffering, avoiding direct impact on the bridge piers, so that the piers can withstand an impact force of 10,000 tons.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
