Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 shows that the utility model provides an buffer stop's in service behavior schematic diagram, buffer stop 20 install around pier 10, when boats and ships striking bridge, weaken boats and ships to the impact of pier, protect the pier.

Referring to fig. 2 to 3, the collision prevention device 20 may include: the energy dissipater 3, the shell, a plurality of supporting pieces 4 and a connecting piece 5; wherein the energy dissipater 3 may be a material with good elasticity and cushioning ability, and the outer shell is arranged outside the energy dissipater 3, and is made of rubber, for example; a plurality of support members 4 may be supported between the dissipater 3 and the casing, a plurality of support members 4 being connected in series by a connector 5, and the connector 5 being fixedly connected to each support member 4 to form a cage-like cushioning enclosure, wherein the connector 5 and/or the support members 4 are for example steel reinforcement. A steel plate 6 is arranged between the cage-shaped buffer enclosure and the energy dissipater 3, the steel plate 6 wraps the energy dissipater 3 inside, and the steel plate has a certain thickness. In the event of an impact, the impact force acts first on the housing and is then distributed by the support 4 and the connecting piece 5 to the adjacent support 4; after the energy of the impact is dispersed to each supporting piece 4, the energy is further buffered by the steel plate 6 and the energy dissipater 3, so that the impact force is reduced, and the damage of the two impacting parties is reduced.

More specifically with reference to the figures, the casing may be constructed in one piece to obtain a more stable structure; the energy dissipater can also be composed of a plurality of first panels 1 and a plurality of second panels 2, the second panels 2 are connected between two adjacent first panels 1, the first panels 1 and the second panels 2 are arranged around the energy dissipater 3, and the rigidity of the first panels 1 is greater than that of the second panels 2; a plurality of the supports 4 are supported between the first panel 1 and the dissipator 3 and between the second panel 2 and the dissipator 3. For example, the first panel 1 may be used to withstand an impact, or to arrange the first panel 1 on an end surface susceptible to impact, for example, when applied to a pier 10 of a river, the first panel 1 may be arranged in a direction perpendicular to a traffic direction of a ship hull. When the first panel 1 bears the impact, the second panel 2 can be deformed, relieving the impact on the first panel 1.

The first panel 1 and the adjacent second panel 2 are configured to be in sliding connection or fixed connection, and it can be understood that when the first panel 1 and the second panel 2 are fixedly connected, the whole housing is more stable; when the first panel 1 and the second panel 2 are connected in a sliding manner, the first panel 1 can obtain a larger deformation space.

The connecting pieces 5 are connected end to end and surround the energy dissipater 3, so that the connecting pieces 5 form a closed structure, on one hand, the connecting pieces can bear loads in all directions, and on the other hand, the closed structure is more beneficial to diffusion of local impact force, and a better buffering effect is achieved.

Fig. 4 shows a cross-sectional view at a of another embodiment of a crash barrier 20, which differs from fig. 2 to 3 in that the energy dissipaters 3 are not enclosed by steel plates 6, but distributed in a cage-like damping enclosure formed by supporting elements 4 and connecting elements 5, forming a combined damping structure, which further increases the damping effect. When the impact occurs, the impact force firstly acts on the shell, then most of the impact force is weakened by the supporting piece 4, the connecting piece 5 and the energy dissipater 3, and finally the impact force is further reduced through the steel plate 6, so that the damage of the two impacting parties is reduced.

In some examples, when applied in the field of river bridge collision avoidance, the dissipaters 3 may be configured to be less dense than water, so that the entire collision avoidance apparatus can float on the water surface without sinking, or so that the housing can at least partially float on the water surface, protecting against impacts from the hull.

It should be noted that the shape of the impact protector 20 may be adjusted according to the environment of use or the shape of the object to be protected, and the shape of the energy dissipater 3 may be changed according to the shape of the impact protector. The cross section of the energy dissipater 3 can be hexagonal or quadrangular, and can also be circular, oval or triangular. The support 4 can be perpendicular to the outer wall of the housing and/or the dissipator 3, or it can be arranged between the outer wall of the housing and/or the dissipator 3 at other angles of inclination, i.e. at other angles it can also act as a support.

According to the description to above-mentioned example and effect, can understand, the utility model provides an anticollision device can be applied to bridge protection, river course bridge protection, also can be applied to road bridge to and the application occasion that needs collision avoidance such as pier.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
