Description

Technical Field

[0001] The utility model relates to the technical field of self-floating pier anti-collision devices, in particular to a rotary pier anti-collision device. Background Technique

[0002] Piers in water are widely used in fields such as water bridges, playing the role of supporting and fixing water projects. In recent years, ship collision accidents with piers have occurred frequently at home and abroad. They not only cause serious losses such as the collapse of water projects and the destruction of ships and deaths of people, but also may cause pollution problems such as the intrusion of toxic chemicals into the water due to the leakage of the hull, directly or indirectly affecting people's lives.

[0003] The invention patent with the publication number of CN115787580A discloses a combined assembled bridge anti-ship collision device, including a number of anti-collision cylinders. The anti-collision cylinders are arranged on the outer wall of the pier for anti-collision. The anti-collision cylinder includes a central cylinder and a rubber cylinder fixedly connected. Honeycomb holes are axially opened on the rubber cylinder. A first connection hole is opened in the central cylinder. Floats are installed below the anti-collision cylinders. A first connection column is rotatably installed on the floats. A first connecting piece is installed between adjacent floats. A second connecting piece is provided between adjacent anti-collision cylinders. The second connecting piece includes a base rod. A first connection ring and an installation column are respectively provided at both ends of the base rod. A second connection column is rotatably installed on the installation column. The second connection column passes through the first connection hole and is circumferentially fixed to the central cylinder, aiming to solve the problems of inconvenient installation and high cost of the current anti-collision device, and at the same time, most of the anti-collision components are fixed on the pier, resulting in more impact force concentrated on the fixed position when being impacted, which is likely to cause damage to the pier and poor anti-collision effect.

[0004] In the above technical solution, in order to reduce the impact energy of the ship, a rotating anti-collision cylinder is provided on the outer side of the pier. However, since a number of anti-collision cylinders are evenly distributed on the outer side of the pier and their outer diameters are relatively small, when the ship impacts one of the anti-collision cylinders, the front end of the ship will move to the middle of this anti-collision cylinder and the adjacent anti-collision cylinder, and its impact direction will also be towards the pier, which is not conducive to improving the anti-collision effect of the anti-ship collision device. Content of the Utility Model

[0005] In view of this, the utility model provides a rotary pier anti-collision device, which can make the direction of part of the impact force generated by the ship impact deviate from the pier, improving the anti-collision effect of the anti-collision device.

[0036] Next, in combination with the specific implementation mode of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described implementation mode is only a part of the implementation modes of the present utility model, rather than all the implementation modes. Based on the implementation modes in the present utility model, all other implementation modes obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0037] As Figures 1-3 shown, a rotary pier anti-collision device of the present utility model includes a fixed frame 1, a floating cylinder 2, a rubber fender 3 and a sliding plate 4. It floats on the water surface and wraps around the circumference of the pier 5 in the water to prevent the hull from directly hitting the pier 5. A rotary pier anti-collision device of the present utility model is mainly applied to a pier 5 with an oblong cross-section.

[0038] Among them, the fixed frame 1 is used to carry other components. The fixed frame 1 is in a ring shape structure and is arranged outside the pier 5.

[0039] The floating cylinder 2 is used to buffer the impact of the ship. It floats on the water surface and provides buoyancy for the fixed frame 1. The floating cylinder 2 includes a first cylinder 21 and a second cylinder 22. The first cylinder 21 and the second cylinder 22 are both rotatably arranged on the fixed frame 1, and their rotation axes are both perpendicular to the horizontal plane. When the ship hits the first cylinder 21 or the second cylinder 22, the rotational connection between the first cylinder 21 or the second cylinder 22 and the fixed frame 1 can be used to change the impact direction of the ship and convert its impact force, thereby reducing the impact damage of the ship to the pier 5. The first cylinder 21 and the second cylinder 22 enclose a ring and are located outside the pier 5, so as to provide comprehensive protection for the pier 5.

[0040] Specifically, the cross-section of the pier 5 is oblong. One first cylinder 21 is respectively arranged at both ends of the fixed frame 1 along the length direction of the cross-section of the pier 5, and its diameter is not less than the width of the cross-section of the pier 5, preferably greater than the width of the cross-section of the pier 5. As Figure 1As shown in the figure, when the ship hits the right side of the first cylinder 21 on the right, it will cause the first cylinder 21 to rotate, thus changing the impact direction of the ship. Since the outer diameter of the first cylinder 21 is not less than the width of the cross-section of the pier 5, the rotation of the first cylinder 21 will deflect the impact direction of the ship from the pier 5, thus ensuring the anti-collision effect of this anti-collision device.

[0041] A plurality of second cylinders 22 are respectively arranged at both ends of the fixing frame 1 along the width direction of the cross-section of the pier 5, that is, the diameter of the second cylinder 22 is smaller than the length of the cross-section of the pier 5. Although its anti-collision effect is weaker than that of the first cylinder 21, it can reduce the occupied space of the floating cylinder 2. By using the diameter cooperation of the first cylinder 21 and the second cylinder 22, the anti-collision effect and the occupied space of this anti-collision device reach a balance.

[0042] The floating cylinder 2 further includes a third cylinder 23. The third cylinder 23 is rotatably arranged on the fixing frame 1 and is located between the first cylinder 21 and the second cylinder 22, and its rotation axis is perpendicular to the horizontal plane. Its effect is the same as that of the first cylinder 21 and the second cylinder 22. The third cylinder 23, the second cylinder 22 and the first cylinder 21 enclose a ring shape, and it also plays a role in filling the gap between the first cylinder 21 and the second cylinder 22.

[0043] In order to minimize the occupied space of this anti-collision device, it is preferred that the diameter of the second cylinder 22 is smaller than the width of the cross-section of the pier 5. And in order to maintain the coherence between the side of the first cylinder 21 away from the pier 5 and the side of the second cylinder 22 away from the pier 5, as Figure 1 shown, it is preferred that the diameter of the third cylinder 23 is larger than the diameter of the second cylinder 22 and smaller than the diameter of the first cylinder 21.

[0044] The fixing frame 1 includes a ring frame 11, a top ring plate 12, a bottom ring plate 13 and a reinforcing ring 14. As Figure 2 shown, the ring frame 11 is arranged on the outer side of the pier 5, and its top view is annular; the top ring plate 12 is fixedly arranged on the top side of the ring frame 11; the bottom ring plate 13 is fixedly arranged on the bottom side of the ring frame 11. The floating cylinder 2 is arranged between the top ring plate 12 and the bottom ring plate 13. By using the limiting effect of the top ring plate 12 and the bottom ring plate 13 on the floating cylinder 2, the floating cylinder 2 can be prevented from detaching from the fixing frame 1, thus improving the fixing stability and firmness of the floating cylinder 2.

[0045] The cross-section of the reinforcing ring 14 is T-shaped, and the reinforcing ring 14 is respectively fixedly arranged on the top side of the top ring plate 12 and the bottom side of the bottom ring plate 13. The T-shaped reinforcing ring 14 can not only play a role in strengthening the structural strength of the fixing frame 1 and prevent it from bending during operation, but also can adjust the position of this anti-collision device by using the cooperation between the reinforcing ring 14 and other equipment.

[0046] For the convenience of processing, transporting and installing the fixing frame 1, it is preferable to make the fixing frame 1 include two C-shaped members and two strip-shaped members. When assembling the fixing frame 1, the two C-shaped members and the two strip-shaped members can be welded and fixed by welding.

[0047] The first cylinder 21 includes a rotating shaft 211, a box body 212 and a buffer material 213. As Figure 2 shown, the rotating shaft 211 is fixedly arranged between the top ring plate 12 and the bottom ring plate 13; the box body 212 is rotatably arranged on the rotating shaft 211, so as to realize the rotational connection between the first cylinder 21 and the fixing frame 1.

[0048] For the convenience of installing the first cylinder 21, the rotating shaft 211 can be detachably and fixedly connected to the top ring plate 12 and the bottom ring plate 13; the box body 212 is arranged outside the rotating shaft 211 and is spaced and rotatably arranged therewith; when assembling the first cylinder 21, first place the box body 212 between the top ring plate 12 and the bottom ring plate 13, then pass the rotating shaft 211 through the top ring plate 12, the box body 212 and the bottom ring plate 13 in sequence, and finally fix the rotating shaft 211 to the top ring plate 12 and the bottom ring plate 13, so as to realize the rapid assembly of the first cylinder 21; of course, the second cylinder 22 and the third cylinder 23 can also use this structure; and in order to avoid the reinforcing ring 14 affecting the assembly of the rotating shaft 211, it is preferable to make the reinforcing ring 14 located on the side of the rotating shaft 211 close to the pier 5.

[0049] For the detachable and fixed connection between the rotating shaft 211 and the top ring plate 12 and the bottom ring plate 13, as Figure 2 shown, a perforation can be opened above the circumferential side of the rotating shaft 211. When the rotating shaft 211 is arranged between the top ring plate 12 and the bottom ring plate 13, a bolt is inserted into this perforation and this bolt abuts against the top side of the top ring plate 12. A circular support can also be fixedly arranged on the lower side of the bottom ring plate 13, and the lower end of the rotating shaft 211 abuts against this circular support. These two methods can both ensure the firmness of the fixation between the rotating shaft 211 and the top ring plate 12 and the bottom ring plate 13.

[0050] The buffer material 213 is filled and arranged in the box body 212. The buffer material 213 can be made of materials with buffer effects such as polyurethane. Thus, when the floating cylinder 2 is impacted, part of the impact force can be absorbed and transformed by the buffer material 213, improving the anti-collision performance of this anti-collision device.

[0051] The rubber fender 3 is used to improve the anti-collision effect of this anti-collision device. The rubber fender 3 is fixedly arranged on the side of the fixing frame 1 close to the pier 5; when this anti-collision device is impacted by a ship, part of the impact force can be absorbed by the elastic deformation of the rubber fender 3.

[0052] The sliding plate 4 is used to increase the service life of the anti-collision device. The sliding plate 4 is fixedly arranged on one side of the rubber fender 3 close to the bridge pier 5. The sliding plate 4 is preferably made of polytetrafluoroethylene material, with a smooth surface and strong wear resistance. When the anti-collision device is impacted by a ship, due to the smoothness of the surface of the sliding plate 4, sliding occurs between the sliding plate 4 and the bridge pier 5, which can reduce the damage generated when the anti-collision device impacts the bridge pier 5.

[0053] To enhance the effects of the rubber fender 3 and the sliding plate 4, it is preferred that both the rubber fender 3 and the sliding plate 4 are arranged in multiple numbers around the center line of the bridge pier 5, and the rubber fender 3 and the sliding plate 4 correspond to each other one by one.

[0054] The working principle of a rotary bridge pier anti-collision device of the present utility model is as follows:

[0055] As Figure 1 shown, when a ship impacts the side of the first cylinder 21 far from the bridge pier 5, by using the rotation of the first cylinder 21, the direction of the impact force generated by the ship impact can be deviated from the bridge pier 5 to mitigate the impact damage of the ship on the bridge pier 5. And when the ship impacts the second cylinder 22 and the third cylinder 23, by using their rotation, the direction of the impact force can also be guided, so that the impact force of the ship is also weakened to a certain extent. Coupled with the absorption of the impact force by the rubber fender 3 and the sliding between the sliding plate 4 and the periphery of the bridge pier 5, the anti-collision performance of the anti-collision device can be improved.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
