Description

Double-protection pier anti-collision device

Technical Field

The utility model relates to a double-protection pier anti-collision device in the technical field of overwater building safety protection.

Background

In order to meet higher and higher shipping requirements, navigation ships are getting bigger, faster and more, and meanwhile, the normal navigation of the ships is influenced by changes of bridge area environments such as flow speed, wind speed, curves, scouring, silting, tide level and the like, so that the occurrence of a ship bridge-collision accident is difficult to avoid.

At present, common anti-collision measures include active anti-collision measures and passive anti-collision measures, wherein the active anti-collision measures include measures of setting a navigation mark, setting a navigation warning area, installing a VTS system and the like so as to reduce the probability of collision between a ship and a pier. Passive collision avoidance measures include: (1) an attached bumper system; (2) a gravity pendulum collision avoidance system; (3) a thin-shell sand-building cofferdam anti-collision system; (4) a capsule sandbag collision avoidance system; (5) an artificial island collision avoidance system; (6) cluster type pier protecting piles; (7) a floating mesh collision avoidance system; (8) non-structural bumper systems, and the like. The anti-collision facilities can be divided into direct structure anti-collision devices and indirect structure anti-collision devices according to different set places, and if the anti-collision facilities are divided into elastic deformation types, crush deformation types and displacement types according to different energy absorption modes in the collision process.

The passive anti-collision device is of a steel structure or a soft structure, but the damage of the pier is prevented at the cost of damaging the anti-collision device and sacrificing the ship, so that the anti-collision device is mostly disposable and needs to be replaced in time after the collision occurs; in addition, in the case of large-tonnage ship impact, the protection function of the anti-collision device is limited, and if the number of layers of the buffer layers is increased, the construction cost is also increased.

Referring to fig. 3, the dual protection pier collision avoidance device in the embodiment of the present invention includes a fixed frame 1, a rotating frame 2, and a buffer block 3. The mount 1 includes a mounting plate 11, and the mounting plate 11 is adapted to be coupled to a surface of a pier. The rotating frame 2 is rotatably connected with the fixed frame 1. The quantity of buffer block 3 is at least three, and all sets up along the axial equidistance interval of swivel mount 2, in other words, buffer block 3 is regular polygon and installs the edge at swivel mount 2 for with the boats and ships contact that takes place to strike.

Referring to fig. 1, the present invention uses the principle of moment balance. The moment balance principle is as follows: the link OA and the link OB are connected to each other at a point O, and the complex OAB is rotatable about the point O. When vessel D is in contact with link OA at point C and vessel D continues to travel, vessel D applies a force F1 to complex OAB. The complex OAB rotates about point O such that the link OB contacts the side of the vessel D and applies a force F2 to the vessel D. Assuming that the OC distance is L1 and the OB distance is L2, the lateral thrust F2 borne by the ship D at this time is (F1 × L1)/L2. It can be seen that according to the principle of moment balance, the lateral thrust F2 is in direct proportion to the impact force F1 of the ship, i.e. the larger the impact force F1 is, the larger the lateral thrust F2 is, so that the impact force is ingeniously converted into the steering force of the ship, and the frontal impact is effectively resolved. Moreover, the device can play a good role in protection no matter whether the ship is a large ship or a small ship.

Referring to fig. 2, in the embodiment of the present invention, the bow of the ship first contacts one of the buffer blocks 3, and drives the rotating frame 2 to rotate. Then another adjacent buffer block 3 will contact with the side of the ship, and as the ship continues to advance, the thrust of the buffer block 3 to the side of the ship will also become larger, so as to push the ship away from the original route. Both the pier and the ship are not damaged too much, only the running direction of the ship is changed, and the speed of the ship is almost not changed, so that the kinetic energy of the ship after collision is basically unchanged, the collision deformation degree and the heat energy consumption between the ship and the device are reduced, and double protection of the pier and the ship is realized. And each buffer block 3 is evenly distributed, so that the buffer blocks can be recycled, and the cost spent in later maintenance is reduced.

Furthermore, the fixing frame 1 is made of steel, so that the fixing frame 1 is prevented from deforming due to impact, and the surface of the fixing frame 1 is provided with an anticorrosive coating to prevent seawater from corroding the structure of the fixing frame 1 for a long time.

Furthermore, the mounting plate 11 is attached to the surface of the pier, so that the stress on the mounting plate 11 and the surface of the pier is uniform, and the possibility of collapse of the anti-collision device due to stress concentration is reduced.

Referring to fig. 4 and 5, further, the fixing frame 1 further includes a hydraulic rod 12 and a connecting member 13, two ends of the hydraulic rod 12 are respectively connected to the mounting plate 11 and the connecting member 13, and the rotating frame 2 is rotatably connected to the connecting member 13. Specifically, the number of the hydraulic rods 12 is two, and the two hydraulic rods are respectively connected to two ends of the connecting member 13 to form a "C" shaped structure. On one hand, the hydraulic rod 12 can enhance the buffer force of the double-protection pier anti-collision device and prevent the anti-collision device from being broken due to overlarge impact force; on the other hand, the hydraulic rod 12 has a limiting effect on the rotating frame 2 connected to the connecting piece 13, and the rotating frame 2 is prevented from being loosened out from the connecting piece 13. It is understood that other elastic buffer structures may be adopted instead of the hydraulic rod 12 to achieve the same technical effect, and the description thereof is omitted.

Further, the buffer block 3 is made of a buoyant material, so that the buffer block 3 can move up and down with the change of the water level, and the buffer block 3 is kept near the water level. In some embodiments, the buffer block 3 and the rotating frame 2 can move up and down; in the present embodiment, the buffer block 3 and the rotating frame 2 as a whole can move up and down with respect to the fixed frame 1.

Furthermore, the buffer blocks 3 are rotatably connected with the rotating frame 2, so that on one hand, the ship can be pushed away from an original route more easily, on the other hand, the ship is always in contact with a certain contact point of the buffer blocks 3, the scratch and the rub of the buffer blocks 3 on the ship body is reduced, and the damage to the ship is further reduced.

In this embodiment, the number of buffer blocks 3 is three, is regular triangle-shaped and distributes, avoids appearing because of distributing too densely and leading to the arm of force to reduce to lead to the condition that lateral thrust reduces.

Further, the buffer block 3 comprises an inner roller 31 and a buffer layer 32, the inner roller 31 serves as a framework and is rotatably connected with the rotating frame 2, and the buffer layer 32 is sleeved on the outer side of the inner roller 31. Specifically, the buffer layer 32 is filled with composite energy dissipation materials, energy dissipation ribs are arranged inside the buffer layer, and energy absorption rubber is paved on the outer side of the buffer layer, so that direct impact of ships can be well absorbed, and the bridge pier, the device and the ships are protected more effectively.

In some embodiments, the bump stop 3 is cylindrical so that the vessel does not deflect upon impact.

In this embodiment, the buffer block 3 is drum-shaped and has a convex middle, so that more energy-absorbing materials can be filled, and a better energy-absorbing effect is achieved.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the utility model as set forth in the claims appended hereto.
