[0029] Reference Figures 1 to 4 The self-floating bridge pier anti-collision device according to an embodiment of the present invention includes an anti-collision ring 100 and an energy dissipation protection structure 200. The anti-collision ring 100 includes two or more first buoyancy units 110, all of which are connected end to end in sequence to form a bridge pier receiving hole 101; the energy dissipation protection structure 200 is disposed on the outer periphery of the anti-collision ring 100 and is connected to the side of the first buoyancy unit 110 away from the bridge pier receiving hole 101.
[0030] When the self-floating pier anti-collision device is in use, the pier is located at the pier receiving hole 101 within the anti-collision ring 100, and the anti-collision ring 100 is located at the water surface. When a ship or floating object moves toward the pier, the ship or floating object first collides with the energy dissipation protection structure 200. The energy dissipation protection structure 200 reduces the risk of the ship or floating object directly impacting the anti-collision ring 100 and plays a buffering role for the ship or floating object, thereby reducing the impact degree of the ship or floating object on the anti-collision ring 100, thus reducing the risk of the anti-collision ring 100 being damaged by collision and improving its service life.
[0031] In the embodiment, the energy dissipation protection structure 200 is provided in two or more and arranged at intervals around the outer periphery of the anti-collision ring 100. Each first buoyancy unit 110 is connected to at least one energy dissipation protection structure 200, and the energy dissipation protection structure 200 is detachably installed on the first buoyancy unit 110.
[0032] Each first buoyancy unit 110 can be connected to one or more energy dissipation protection structures 200 on the side opposite to the pier receiving hole 101, which enhances the protection effect on each first buoyancy unit 110. When some energy dissipation protection structures 200 are damaged, the self-floating pier anti-collision device can also be maintained by disassembly and replacement, thereby improving the overall service life of the self-floating pier anti-collision device.
[0033] Specifically, in this embodiment, each energy dissipation protective structure 200 is installed on a first buoyancy unit 110. The anti-collision ring 100 has eight first buoyancy units 110 and twenty-four energy dissipation protective structures 200, with each first buoyancy unit 110 having three energy dissipation protective structures 200 installed on it. It is conceivable that in other embodiments, the number of energy dissipation protective structures 200 can be other numbers, such as two, three or more, and the number of first buoyancy units 110 can also be two, three or more, with each first buoyancy unit 110 connected to one, two or more energy dissipation protective structures 200. Those skilled in the art can choose according to actual needs.
[0034] In this embodiment, the energy dissipation protection structure 200 includes a protective box 210 and a first energy-dissipating filler 220. The protective box 210 has a first receiving cavity, and the first energy-dissipating filler 220 is located within the first receiving cavity. The protective box 210 is filled with the first energy-dissipating filler 220, which gives the energy dissipation protection structure 200 a better ability to absorb kinetic energy, reducing the impact of ships or floating objects on the anti-collision ring 100. The structure is relatively compact, and the protective box 210 facilitates the fixation of the position of the first energy-dissipating filler 220. Specifically, the first energy-dissipating filler 220 is polyurethane foam, which has good elasticity and low density, and can improve the buoyancy of the energy dissipation protection structure 200, allowing the anti-collision ring 100 to float better on the water surface. It is conceivable that the first energy-dissipating filler 220 can also be other types of foamed fillers, such as ethylene vinyl acetate copolymer foam, or the first energy-dissipating filler 220 can also be a corrugated pipe or a spring, which dissipates the impact kinetic energy of ships and floating objects through elastic deformation.
[0035] In this embodiment, the protective box 210 is provided with a first partition 211 located within the first accommodating cavity. The first partition 211 divides the first accommodating cavity into at least two first accommodating sub-cavities, all of which are filled with a first energy-dissipating filler 220. The first partition 211 can separate the first energy-dissipating filler 220 within the protective box 210 and helps to improve the overall structural strength of the protective box 210, thereby improving the impact resistance of the energy-dissipating protective structure 200. It exhibits high structural strength and good overall performance.
[0036] Specifically, the first partition 211 can divide the first accommodating cavity into two, three, four or more first accommodating sub-cavities, which can be selected by those skilled in the art according to actual needs.
[0037] In this embodiment, the protective box 210 is provided with three first partitions 211, at least two of which are perpendicular to each other. Specifically, two of the first partitions 211 are arranged vertically and the other first partition 211 is arranged horizontally, so that some of the first partitions 211 are perpendicular to each other, thereby significantly improving the overall structural strength of the protective box 210 and resulting in a high overall structural strength of the energy dissipation and protection structure 200.
[0038] It is conceivable that the protective box 210 may also be provided with one, two or more first partitions 211, and the layout of the first partitions 211 may also be in other ways, which can be selected by those skilled in the art according to actual needs.
[0039] In this embodiment, the anti-collision ring 100 further includes a partition structure 120 located within the pier receiving hole 101. Both ends of the partition structure 120 are connected to the hole wall of the pier receiving hole 101, dividing the pier receiving hole 101 into two pier receiving holes 102. Since some piers have two pier bodies, dividing the pier receiving hole 101 into two pier receiving holes 102 by the partition structure 120 allows each pier body to receive high levels of anti-collision protection. Furthermore, the anti-collision ring 100 can be associated with both pier bodies, improving the protective performance of the anti-collision ring 100 for the entire pier.
[0040] In this embodiment, the partition structure 120 includes two second buoyancy units 121, all of which are connected sequentially. The second buoyancy units 121 located at both ends of the partition structure 120 are connected to the first buoyancy unit 110, respectively. By using two second buoyancy units 121 connected sequentially to form the partition structure 120, the second buoyancy units 121 can further provide buoyancy to the anti-collision ring 100, and the structure is relatively simple.
[0041] In this embodiment, the first buoyancy unit 110 includes a shell 111 and a second energy-dissipating filler 112. The shell 111 has a second accommodating cavity, and the second energy-dissipating filler 112 is located within the second accommodating cavity. By placing the second energy-dissipating filler 112 within the second accommodating cavity of the shell 111, the first buoyancy unit 110 has a better ability to absorb kinetic energy, reducing the impact of ships or floating objects on the bridge piers. The structure is relatively compact, and the shell 111 facilitates the fixation of the position of the second energy-dissipating filler 112. Specifically, the material of the second energy-dissipating filler 112 is the same as that of the first energy-dissipating filler 220, that is, the second energy-dissipating filler 112 is also polyurethane foam, which has good elasticity and low density, and can improve the buoyancy of the first buoyancy unit 110, allowing the anti-collision ring 100 to float better on the water surface. It is conceivable that the second energy-dissipating filler 112 could also be other types of foamed fillers, such as ethylene vinyl acetate copolymer foam, or the second energy-dissipating filler 112 could also be a corrugated pipe or a spring, which would dissipate the impact kinetic energy of the ship and floating objects through elastic deformation.
[0042] Specifically, a second partition is provided inside the housing 111. The second partition separates the second energy-consuming filler 112 in the second accommodating cavity. The second partition can improve the structural strength of the housing.
[0043] In this embodiment, the shell 111 is made of steel-coated composite material. Both ends of the shell 111 are provided with connecting flanges 113 and connecting compartments 114. The connecting compartments 114 have hatches. The connecting flanges 113 are located inside the connecting compartments 114. The connecting compartments 114 of two adjacent first buoyancy units 110 are connected through the hatches. The connecting flanges 113 of two adjacent first buoyancy units 110 are connected. The inner wall of the connecting compartment 114 is provided with an anti-corrosion layer. The connecting compartment 114 is isolated from the second accommodating cavity. The shell 111 is made of steel-clad composite material, which is a composite material layer set on the surface of a steel plate. The composite material layer can be fiber-reinforced composite material with low density, high strength and corrosion resistance, and soft texture, which makes the shell 111 structurally strong, corrosion-resistant, and has good cushioning performance. Two adjacent first buoyancy units 110 are connected by connecting flanges 113, and the connecting flanges 113 are located inside the connecting compartment 114. The walls of the connecting compartment 114 can protect the connecting flanges 113, and the inner wall of the connecting compartment 114 has an anti-corrosion layer. When the anti-collision ring 100 floats on the water surface, water can easily enter the connecting compartment 114. Therefore, the anti-corrosion layer can provide anti-corrosion protection for the interior of the connecting compartment 114, improving the durability of the shell 111.
[0044] Specifically, the connecting flange 113 can be a flange plate or other types of flange structures, which are not limited here. The anti-corrosion coating can be paint or composite material, which are not limited here.
[0045] Specifically, the shell 111 isolates the second accommodating cavity from the connecting chamber 114 through a watertight plate, so that water will not enter the second accommodating cavity through the connecting chamber 114, reducing the risk of water entering the second accommodating cavity.
[0046] In this embodiment, the anti-collision ring 100 is provided with a buffer 130 and a wear-resistant component 140. One side of the buffer 130 is connected to the wall of the pier receiving hole 101, and the wear-resistant component 140 is connected to the other side of the buffer 130. Under the action of wind and waves, the wall of the pier receiving hole 101 of the anti-collision ring 100 is prone to contact and friction with the pier, causing wear to the inner side of the anti-collision ring 100 and making it susceptible to damage. Therefore, a buffer 130 is provided at the hole wall of the pier receiving hole 101 of the anti-collision ring 100. The buffer 130 can reduce the direct contact friction between the first buoyancy unit 110, the second buoyancy unit 121 and the pier, thereby reducing the wear risk of the first buoyancy unit 110 and the second buoyancy unit 121. In addition, the buffer 130 is also provided with a wear-resistant part 140. The wear-resistant part 140 improves the wear resistance of the inner side of the anti-collision ring 100, thereby reducing the risk of wear of the buffer 130 and extending the service life of the anti-collision ring 100.
[0047] Specifically, the buffer 130 is provided with multiple buffers arranged around the hole wall of the pier body receiving hole 102, and the first buoyancy unit 110 and the second buoyancy unit 121 are both connected to the buffer 130.
[0048] Specifically, the buffer 130 is made of elastic rubber or other polymer materials, capable of absorbing the collision kinetic energy between the anti-collision ring 100 and the bridge pier. This not only reduces the impact between the anti-collision ring 100 and the bridge pier but also reduces the impact of ships or floating objects on the bridge pier. Optionally, the buffer 130 may have a cavity inside, thereby improving the buffering performance of the buffer 130.
[0049] Specifically, the wear-resistant part 140 can be made of polymer materials or directly from discarded tires, which has a relatively low cost, good performance and is energy-saving and environmentally friendly; or it can be made of plastic buckets, etc.
[0050] Specifically, the second buoyancy unit 121 has the same structure as the first buoyancy unit 110, which will not be described in detail here. The first buoyancy unit 110 and the second buoyancy unit 121 are also connected by a connecting flange 113, and a connecting compartment 114 is also provided on the outside of the connecting flange 113.
[0051] Specifically, both the first buoyancy unit 110 and the second buoyancy unit 121 have maintenance manholes 150 on their upper sides, and each manhole 150 is fitted with a sealing cover. By providing the maintenance manholes 150 and sealing covers, when maintenance is required on the first buoyancy unit 110 or the second buoyancy unit 121, maintenance personnel can open the sealing covers and enter the first buoyancy unit 110 or the second buoyancy unit 121 through the maintenance manholes 150 to perform maintenance. After maintenance is completed, the sealing covers are closed again to prevent water from accidentally entering the first buoyancy unit 110 or the second buoyancy unit 121.
[0052] This utility model's self-floating bridge pier anti-collision device features a flexible overall structure, high buffering and energy absorption efficiency, excellent corrosion resistance, durability, impact resistance, and fatigue resistance. It is cost-effective, lightweight, easy to transport, install, and replace, and environmentally friendly. When coated with a specific color, it can also serve as a warning.
