[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Figure 1 The figure shows a schematic diagram of the use of the anti-collision device provided by the present invention. The anti-collision device 20 is installed around the bridge pier 10. When a ship hits the bridge, the impact force of the ship on the bridge pier is weakened, thereby protecting the bridge pier.

[0030] Reference Figures 2 to 3As shown, the anti-collision device 20 may include an energy dissipator 3, an outer shell, multiple supports 4, and connectors 5. The energy dissipator 3 may be made of a material with excellent elasticity and cushioning properties. The outer shell is disposed outside the energy dissipator 3 and may be made of, for example, rubber. Multiple supports 4 may be supported between the energy dissipator 3 and the outer shell. The connector 5 connects the multiple supports 4 in series and is fixedly connected to each support 4, forming a cage-like buffer enclosure. The connectors 5 and / or the supports 4 may be, for example, steel bars. A steel plate 6 is disposed between the cage-like buffer enclosure and the energy dissipator 3, encasing the energy dissipator 3. The steel plate 6 has a certain thickness. During a collision, the impact force first acts on the outer shell and is then dispersed to adjacent supports 4 by the supports 4 and connectors 5. After the impact energy is dispersed to each support 4, it is further buffered by the steel plate 6 and the energy dissipator 3, reducing the impact force and minimizing damage to both parties.

[0031] More specifically, referring to the figure, the shell can be constructed as an integral body to obtain a more stable structure; it can also be composed of multiple first panels 1 and multiple second panels 2, with the second panel 2 connected between two adjacent first panels 1, and the first panel 1 and the second panel 2 are both arranged around the energy dissipation body 3, and the first panel 1 has a stiffness greater than that of the second panel 2; multiple support members 4 are supported between the first panel 1 and the energy dissipation body 3, and between the second panel 2 and the energy dissipation body 3. For example, during use, the first panel 1 can be used to withstand impact, or the first panel 1 can be arranged on an end face that is easily impacted. For example, when used on a bridge pier 10 in a river channel, the first panel 1 can be arranged along a direction perpendicular to the passage direction of the hull. When the first panel 1 withstands an impact, the second panel 2 can deform to alleviate the impact on the first panel 1.

[0032] The first panel 1 and the adjacent second panel 2 are configured to be slidingly connected or fixedly connected. It can be understood that when the first panel 1 and the second panel 2 are fixedly connected, the overall shell is more stable; when the first panel 1 and the second panel 2 are slidingly connected, the first panel 1 can obtain a larger deformation space.

[0033] The connector 5 is connected end to end and surrounds the energy dissipation body 3, so that the connector 5 forms a closed structure. On the one hand, it can withstand loads in all directions. On the other hand, the closed structure is more conducive to the diffusion of local impact force, achieving a better buffering effect.

[0034] Figure 4 A cross-sectional view of another embodiment of the anti-collision device 20 is shown. Figures 2 to 3The difference is that the energy dissipator 3 is not enclosed by the steel plate 6, but is instead distributed within a cage-like buffer layer formed by the support members 4 and the connectors 5, forming a combined buffer structure that further enhances the buffering effect. In the event of a collision, the impact force first acts on the outer shell, then is largely weakened by the support members 4, the connectors 5, and the energy dissipator 3. Finally, the impact force is further reduced by the steel plate 6, minimizing damage to both sides of the collision.

[0035] In some examples, when used in the field of river bridge collision avoidance, the energy dissipation body 3 can be configured to have a density less than that of water, so that the entire collision avoidance device can float on the water surface without sinking, or the shell can at least partially float on the water surface to prevent collision from the hull.

[0036] In addition, it should be noted that the shape of the anti-collision device 20 can be adjusted according to the operating environment or the shape of the protected object, and the shape of the energy dissipation body 3 also changes with the shape of the anti-collision device. The cross-sectional shape of the energy dissipation body 3 can be hexagonal, quadrilateral, circular, elliptical, triangular, etc. The support member 4 can be perpendicular to the outer wall of the outer shell and / or the outer wall of the energy dissipation body 3, and can also be arranged at other inclined angles between the outer wall of the outer shell and / or the outer wall of the energy dissipation body 3, that is, it can also play a supporting role at other angles.

[0037] Based on the description of the above examples and their effects, it can be understood that the anti-collision device provided by the present invention can be applied to bridge protection, river bridge protection, and can also be applied to road bridges, docks and other application scenarios that require anti-collision protection.

[0038] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
