Description

Technical Field

[0001] The utility model relates to the technical field of self-floating pier anti-collision devices, in particular to an anti-collision device for variable-section piers. Background Art

[0002] Piers in water are widely used in fields such as water bridges, playing a role in supporting and fixing water projects. In recent years, ship collision accidents with piers have occurred frequently both 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 may also 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 utility model with the publication number of CN215561866U discloses a telescopic anti-collision ship device adapted to a variable-section pier, including a pier body and an anti-collision ship device body arranged in a circle around the pier body. The anti-collision ship device body includes two groups of steel shells connected by a telescopic mechanism. Each group of the steel shells is internally provided with a group of vertical partitions. An elastic buffer energy-absorbing material body is filled in the cavity formed by the vertical partitions and the outer side surface of the steel shells. The two groups of steel shells of the anti-ship collision device are connected by a telescopic mechanism, which can adjust the distance between the two groups of steel shells while floating with the water level to adapt to the variable-section pier body, especially the pier body of large bridges, and can avoid phenomena such as rotation around the pier and jamming during the floating process, and has a good anti-collision effect.

[0004] In the above technical solution, in order to make the anti-collision ship device adapt to the variable-section pier, two steel shells connected by a telescopic mechanism are provided. However, the telescopic mechanism is a hydraulic telescopic rod, and the telescopic function of the telescopic mechanism still needs to be cooperatively controlled by other devices, which is not conducive to the simplified design of the pier anti-collision structure.

[0036] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the specific embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] As Figures 1-7 shown, the anti-collision device for a variable cross-section pier of the present utility model includes two C-shaped floating boxes 1, two springs 2, two limiting frames 3, a plurality of limiting ropes 4, an anchor chain 5, and a buffer material 6, which are used to float on the water surface 7 and cover the periphery of the submerged pier 8 to prevent the hull from directly hitting the submerged pier 8.

[0038] Among them, the C-shaped floating box 1 is the main structure of the anti-collision device. The two C-shaped floating boxes 1 are arranged oppositely and can float on the water surface 7. The C-shaped floating box 1 moves vertically with the rise and fall of the water surface 7 to wrap and protect the position on the periphery of the submerged pier 8 at the water surface 7.

[0039] The spring 2 is used to adjust the distance between the two C-shaped floating boxes 1. The two ends of the spring 2 are respectively fixedly arranged on the two C-shaped floating boxes 1. The two C-shaped floating boxes 1 and the two springs 2 form an enclosing cavity 101, and the submerged pier 8 is arranged in the enclosing cavity 101; as Figure 1 and Figure 2 shown, the cross-section of the submerged pier 8 gradually increases from bottom to top. When the water surface 7 rises, the buoyancy of the C-shaped floating box 1 will drive it to move upward. The C-shaped floating box 1 abuts against the side wall of the submerged pier 8, causing the spring 2 to stretch, thereby increasing the cross-sectional area of the enclosing cavity 101. When the water surface 7 drops, the C-shaped floating box 1 moves downward under the action of its own gravity. At the same time, the elastic force of the spring 2 will cause the spring 2 to automatically contract, thereby reducing the cross-sectional area of the enclosing cavity 101, so that the anti-collision device can adapt to submerged piers 8 with different cross-sectional areas.

[0040] When the position of the water surface 7 is too high or too low, to prevent the ship from hitting the bottom or hitting the bridge, the ship will not be allowed to navigate in the water. The first height 701 is the lowest navigable water level of the water surface 7, and the second height 702 is the highest navigable water level of the water surface 7. When the height of the water surface 7 is not less than the first height 701 and not greater than the second height 702, the ship can navigate on the water surface 7. When the height of the water surface 7 is equal to the first height 701, the spring 2 is in its natural state. The natural state of the spring 2 refers to the state when the spring 2 is not subjected to external forces, that is, the spring 2 is in its original length without being stretched or compressed. Thus, when the anti-collision device is at the position of the lowest navigable water level, the cross-sectional area of the enclosing cavity 101 is minimized, and the fatigue degree of the spring 2 is reduced.

[0041] As Figure 3 and Figure 4 shown, both ends of the C-shaped floating box 1 are provided with installation grooves 102, and both ends of the limiting frame 3 are respectively slidably arranged in the installation grooves 102 on the two C-shaped floating boxes 1. By using the sliding fit between the limiting frame 3 and the two C-shaped floating boxes 1, the two C-shaped floating boxes 1 can be made more stable when separating or approaching.

[0042] As Figure 5 shown, the limiting frame 3 includes a sliding frame 31 and a plurality of rollers 32. The sliding frame 31 is arranged in the installation groove 102; the plurality of rollers 32 are respectively rotatably arranged on the top side and the bottom side of the sliding frame 31 and are respectively in rolling connection with the top side and the bottom side in the installation groove 102. By using the rotational fit between the rollers 32 and the sliding frame 31 and their rolling fit with the inner wall of the installation groove 102, the sliding friction between the limiting frame 3 and the installation groove 102 can be reduced, which is beneficial to improving the service life of the anti-collision device.

[0043] Regarding the specific structure of the sliding frame 31, the sliding frame 31 can include a top frame 311, a bottom frame 312 and a plurality of connecting rods 313. As Figure 5 shown, the top frame 311 and the bottom frame 312 are opposite and spaced apart, and are both located in the installation groove 102. The plurality of rollers 32 are respectively rotatably arranged on the top side of the top frame 311 and the bottom side of the bottom frame 312; the plurality of connecting rods 313 are fixedly arranged between the top frame 311 and the bottom frame 312, and its structure is simple and convenient to maintain.

[0044] As Figure 5 shown, the spring 2 is arranged above the top frame 311, the bottom frame 312 and the plurality of connecting rods 313, and is located above the water surface 7, so that the spring 2 is as far away from the water body as possible, reducing the corrosion speed of the spring 2, and thus improving the service life of the anti-collision device.

[0045] The limiting rope 4 is used to limit the limiting frame 3 to prevent the limiting frame 3 from separating from the C-shaped floating box 1. Both ends of the limiting rope 4 are fixedly arranged in the installation groove 102 and on the limiting frame 3 respectively, and one limiting rope 4 is arranged at each end of each limiting frame 3. As Figure 4 shown, when the two C-shaped floating boxes 1 are separated, the two limiting ropes 4 are in a taut state to tension and fix the C-shaped floating box 1 and the limiting frame 3. As Figure 3 shown, when the two C-shaped floating boxes 1 approach each other, the two limiting ropes 4 are in a relaxed state, thus ensuring the connection and cooperation between the limiting frame 3 and the C-shaped floating box 1.

[0046] The anchor chain 5 is used to limit the travel length of the two C-shaped floating boxes 1. As Figure 6 and Figure 7 shown, both ends of the anchor chain 5 are fixedly arranged on the two C-shaped floating boxes 1 respectively. When the two C-shaped floating boxes 1 are separated, the anchor chain 5 will be in a taut state to prevent the distance between the two C-shaped floating boxes 1 from continuing to separate after being greater than the specified distance. When the two C-shaped floating boxes 1 approach each other, the anchor chain 5 is in a relaxed state.

[0047] As Figure 1 and Figure 3 shown, the end of the spring 2 is located in the installation groove 102, and when the height of the water surface 7 is equal to the first height 701, the end faces of the two C-shaped floating boxes 1 are in contact with each other to reduce the distance between the two C-shaped floating boxes 1 and improve the stability of the anti-collision device.

[0048] The buffer material 6 is used to improve the anti-collision and buffering performance of the C-shaped floating box 1. The buffer material 6 is filled in the C-shaped floating box 1, and materials with buffering performance such as foam and rubber can be used.

[0049] In order to improve the buffering performance of the C-shaped floating box 1, a gap can also be provided between the C-shaped floating box 1 and the underwater pier 8. As Figure 6 shown, when the ship hits the C-shaped floating box 1, the C-shaped floating box 1 can move a certain distance first and then collide with the underwater pier 8.

[0050] The working principle of the anti-collision device for the variable cross-section pier of the present utility model is as follows:

[0051] Taking the cross-sectional area of the underwater pier 8 gradually increasing from bottom to top as an example. As Figure 1 and Figure 2As shown in the figure, when the water surface 7 rises, the buoyancy of the C-shaped floating box 1 will drive it to move upward. The C-shaped floating box 1 abuts against the side wall of the pier 8 in the water, causing the spring 2 to elongate, thereby increasing the cross-sectional area of the enclosed cavity 101. When the water surface 7 drops, the C-shaped floating box 1 moves downward under the action of its own gravity. At the same time, the elastic force of the spring 2 causes the spring 2 to automatically contract, thereby reducing the cross-sectional area of the enclosed cavity 101. This not only enables the anti-collision device to protect the pier 8 in the water in real time according to the change in the height of the water surface 7, but also allows the anti-collision device to adaptively adjust according to the change in the cross-section of the pier 8 in the water. By setting the limit frame 3, the limit rope 4, and the anchor chain 5, the stable use of the anti-collision device can be ensured.

[0052] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
