Description

Technical Field

[0001] The present invention relates to the technical field of bridge anti-collision, and particularly to a multi-stage energy-consuming self-floating ship anti-collision device. Background Art

[0002] At present, the widely used ship anti-collision devices in China are mainly self-floating anti-collision facilities made of steel-composite materials. Such devices float on the water surface relying on their own buoyancy and withstand the impact force through their own structures during ship collisions. However, in waterways with high navigation levels and maritime environments, there are often super-large-tonnage ships passing by. When the existing steel-composite material self-floating anti-collision facilities are impacted at high speed by ships of this level, they mainly rely on their own stiffness to directly withstand the huge impact force, resulting in structural damage or even destruction. In addition, due to the structural characteristics of the steel-composite material self-floating anti-collision facilities, their energy absorption and energy dissipation capabilities are relatively limited, and it is difficult to effectively reduce the transmission of impact energy, resulting in a relatively large impact force still acting on the bridge pier, posing a serious threat to the safety of the bridge.

[0003] Therefore, the existing technology has problems such as insufficient anti-impact ability, poor energy dissipation effect, and limited protection effect on the bridge pier when facing the impact of super-large-tonnage ships. There is an urgent need to develop a multi-stage energy-consuming self-floating ship anti-collision device with a simple structure, a multi-stage energy-consuming mechanism, and a significant energy dissipation effect to improve the bridge protection ability and reduce the risk of damage to the bridge structure caused by ship collisions.

[0014] Preferably, the buffer member is made of at least one of rubber, PE material or polytetrafluoroethylene material.

[0015] The technical solution adopted by the present invention can achieve the following beneficial effects: 1. Through the multi-stage structure design of the first floating energy dissipation mechanism and the second floating energy dissipation mechanism, and in cooperation with the arrangement of the energy dissipation members and the connecting frame, the present application realizes a collision prevention mechanism of gradually dissipating energy. When the ship impacts the device, the first floating energy dissipation mechanism first deflects and squeezes the first group of energy dissipation members, and then the energy is gradually transmitted to the connecting frame, the second group of energy dissipation members and the second floating energy dissipation mechanism, successively completing deformation to absorb the impact force. This energy dissipation method can greatly reduce the instantaneous impact force borne by a single structure, thereby effectively reducing the direct action of the impact energy on the pier, reducing the risk of pier damage, and improving the safety and durability of the bridge. Compared with the traditional single-stage energy dissipation device, the multi-stage energy dissipation scheme of the present application disperses the energy and absorbs it in a gradient manner, avoiding the failure of the collision prevention device or the damage of the pier caused by excessive single-point stress, and enhancing the overall protection ability; 2. Inside the steel structure boxes of the first floating energy dissipation mechanism and the second floating energy dissipation mechanism, support members are reasonably arranged, including the first support part, the second support part and the third support part. These support members interact with each other, not only enhancing the overall rigidity and stability of the box, but also effectively dispersing the impact load, enabling the collision prevention device to maintain the structural integrity when impacted by the ship and avoiding local failure. At the same time, the inclined arrangement of the support members further optimizes the load transfer path, enabling the impact force to be dispersed along a reasonable direction and preventing stress concentration. In addition, the first energy dissipation filler part and the second energy dissipation filler part are respectively filled in the key stress-bearing parts, further enhancing the overall energy absorption effect, enabling the collision prevention device to exert a stable energy dissipation ability under different impact conditions, and ensuring long-term stable operation; 3. On the outer wall surfaces of the first floating energy dissipation mechanism and the second floating energy dissipation mechanism, a first energy dissipation baffle and a second energy dissipation baffle are respectively provided and fixed by energy dissipation bolts. When the device is impacted, the energy dissipation baffle moves along the impact direction under the impact until the energy dissipation bolt is cut off, releasing the impact energy. This design allows the energy dissipation baffle to provide a certain buffer in the initial stress stage, prolonging the energy dissipation time, thereby reducing the instantaneous impact load. In addition, a buffer member is also provided between the ship collision prevention device and the pier. The buffer member is made of high-energy consumption materials such as rubber, PE material or polytetrafluoroethylene, and further absorbs the remaining energy when the device contacts the pier, preventing additional damage to the pier caused by secondary impact. This multi-level buffer design enables the collision prevention device to adapt to the impact conditions of ships of different tonnages, enhancing the protection ability, and even when the device is damaged, it can still maintain a certain buffer and energy dissipation ability to ensure the safety of the pier.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0020] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means that the related objects before and after are in an "or" relationship.

[0021] The following combines the attached Figures 1 to 11 to describe in detail a multi-stage energy-consuming self-floating ship collision prevention device provided by this application through specific embodiments and their application scenarios.

[0022] A multi-stage energy-consuming self-floating ship collision prevention device, combined with Figure 1 , Figure 2 , which includes a first floating energy dissipation mechanism 100, a second floating energy dissipation mechanism 200, a connecting frame 300, and an energy-consuming member 400; wherein, the first floating energy dissipation mechanism 100 is connected to the outer periphery of the second floating energy dissipation mechanism 200, the second floating energy dissipation mechanism 200 is sleeved around the outer periphery of the pier 600 at intervals, and both the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 can float on the water surface.

[0023] At the same time, a plurality of them are provided between the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200, and the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 can slide relative to the connecting frame 300. Exemplarily, the cross-sectional shape of the pier 600 is rectangular, and the number of corresponding connecting frames 300 is four, and one is arranged on each side of the pier 600. Further, the sliding direction of the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 relative to the connecting frame 300 is the collision direction, that is, after a large ship in motion hits the outer surface of the first floating energy dissipation mechanism 100, the first floating energy dissipation mechanism 100 can move relative to the connecting frame 300 in the force direction of the impact.

[0024] Furthermore, two sets of energy-consuming members 400 are provided on each connecting frame 300. For example, if four connecting frames 300 are provided, then eight corresponding energy-consuming members 400 are provided. Exemplarily, one set of energy-consuming members 400 is fixedly provided between the first floating energy-dissipating mechanism 100 and the connecting frame 300, and the other set of energy-consuming members 400 is fixedly provided between the second floating energy-dissipating mechanism 200 and the connecting frame 300, and the stiffness of both the first floating energy-dissipating mechanism 100 and the second floating energy-dissipating mechanism 200 is greater than that of the energy-consuming member 400; in the case of an external impact, the first floating energy-dissipating mechanism 100 deflects inward and sequentially presses the first set of energy-consuming members 400, the connecting frame 300, the second set of energy-consuming members 400, and the second floating energy-dissipating mechanism 200, so as to achieve step-by-step energy dissipation through sequential compressive deformation.

[0025] On this basis, through the mutual cooperation of the first floating energy-dissipating mechanism 100, the second floating energy-dissipating mechanism 200, the connecting frame 300, and the energy-consuming member 400, step-by-step energy dissipation is achieved, thereby effectively reducing the transmission of the ship impact energy and improving the protection ability of the bridge. The technical effects of this device are reflected in the following aspects: First, through the double-layer arrangement of the first floating energy-dissipating mechanism 100 and the second floating energy-dissipating mechanism 200, a multi-stage energy-dissipating structure is formed. When the ship impacts, the first floating energy-dissipating mechanism 100 first contacts the impact force and deflects inward. Since the first set of energy-consuming members 400 is provided between it and the connecting frame 300, the deflection of the first floating energy-dissipating mechanism 100 first causes the compressive deformation of the first set of energy-consuming members 400, thereby initially absorbing the impact energy; with the continuous action of the impact energy, the first floating energy-dissipating mechanism 100 further deflects and pushes the connecting frame 300 to move inward, thereby squeezing the second set of energy-consuming members 400, causing the second set of energy-consuming members 400 to deform and absorb part of the impact energy. Finally, the impact force acts on the second floating energy-dissipating mechanism 200. Under the buffering effect of the energy-consuming member 400, the impact force has been greatly weakened, so that the remaining energy borne by the second floating energy-dissipating mechanism 200 is small, reducing the risk of its damage. Compared with the existing steel-composite self-floating anti-collision facilities that mainly rely on structural stiffness to withstand impacts, the present invention absorbs and disperses the impact force in stages through multi-stage sliding and the step-by-step deformation of the energy-consuming member 400, greatly reducing the risk of excessive stress on a single structure, avoiding direct structural damage, improving the anti-impact ability and energy absorption effect of the device, thereby effectively reducing the direct acting force of the impact energy on the pier 600 and enhancing the safety and durability of the bridge structure.

[0026] In some embodiments, in combination with Figure 2 、 Figure 3, the first floating energy dissipation mechanism 100 includes a first steel structure box body 110, a support member 120, and an energy dissipation filling member 130. Among them, the first steel structure box body 110 has an annular cavity, and a plurality of support members 120 are arranged in the annular cavity to support the first steel structure box body 110; the energy dissipation filling member 130 is embedded in the first steel structure box body 110 and located in the gaps between the plurality of support members 120, and the density of the energy dissipation filling member 130 is less than the density of water.

[0027] Exemplarily, the corners of the first steel structure box body 110 are provided with smooth transitions. That is, there are no sharp corners at the corner parts of the first steel structure box body 110, but smooth arc-shaped corner surfaces, so as to avoid the ship hitting the sharp parts and aggravating the damage.

[0028] Exemplarily, in combination with Figure 4 , Figure 5 , the energy dissipation filling member 130 includes a first energy dissipation filler part 131 and a second energy dissipation filler part 132, and the structural strength of the first energy dissipation filler part 131 is greater than that of the second energy dissipation filler part 132; the first energy dissipation filler part 131 is filled in the gap part corresponding to the corner of the first steel structure box body 110 in the annular cavity, and the second energy dissipation filler part 132 is filled in the gap part in the annular cavity avoiding the corner of the first steel structure box body 110. Further, the first energy dissipation filler part 131 can be selected from foam metals (such as foam aluminum or foam nickel) or high-strength honeycomb materials to provide a stronger energy absorption effect when being impacted. Similarly, the second energy dissipation filler part 132 can adopt polymer buffer materials (such as EVA foam or polyurethane foam) to ensure that it can still provide a basic energy dissipation function while reducing the overall weight. Such a setting can enable both the second energy dissipation filler part 132 and the first energy dissipation filler part 131 to have the performance of reducing the impact energy and also have a certain structural strength. From the perspective of material selection, the structural strength of the second energy dissipation filler part 132 is less than that of the first energy dissipation filler part 131, so that when the ship impacts from the corner part of the first steel structure box body 110 instead of directly from the front, it still does not affect the multi-stage energy consumption performance of the present application.

[0029] On this basis, the design of the annular cavity reduces the overall weight of the first steel structure box body 110, while forming a closed space, improving its buoyancy and enabling it to float stably on the water surface. Secondly, the energy dissipation filling member 130 is embedded in the steel structure box body and located between multiple support members 120, enabling it to deform and absorb impact energy when being impacted, thereby enhancing the buffering capacity of the anti-collision device. The density of the energy dissipation filling member 130 is less than that of water, which not only enhances the buoyancy of the first steel structure box body 110, but also avoids the problem of the energy dissipation filling member 130 increasing the overall weight of the first steel structure box body 110, ensuring that it can float stably on the water surface for a long time and provide an effective anti-collision function.

[0030] Meanwhile, by adopting a first energy dissipation filler part 131 with stronger energy dissipation ability at the corners of the first steel structure box body 110 and filling a second energy dissipation filler part 132 with relatively lower energy dissipation ability at non-corner positions, it is ensured that the parts with greater structural stress have stronger anti-impact ability, while lighter energy dissipation fillers are used in areas with less stress, thereby optimizing the overall energy absorption efficiency. The first energy dissipation filler part 131 can be made of foam metal (such as foam aluminum or foam nickel) or high-strength honeycomb material to provide a stronger energy absorption effect when being impacted, while the second energy dissipation filler part 132 can adopt polymer buffer materials (such as EVA foam or polyurethane foam) to ensure that it can still provide a basic energy dissipation function while reducing the overall weight. Through this arrangement, the ship anti-collision device of the present application can achieve targeted energy absorption and buffering at different parts, enabling the impact energy to gradually decay during the transmission process, avoiding local stress concentration, reducing the risk of structural damage, and improving the overall anti-impact performance and service life. Finally, the device can effectively solve the defects in the prior art such as too high rigidity of the anti-collision facilities, limited overall energy absorption capacity, and easy damage of the structure, thereby improving the protection ability of the bridge and reducing the risk of damage to the bridge caused by ship impact.

[0031] In some embodiments, in combination with Figure 2 , Figure 5 , the second floating energy dissipation mechanism 200 includes a second steel structure box body 210 and a buffer member 220. Among them, the second steel structure box body 210 is hollow inside, and support members 120 and a second energy dissipation filler part 132 are also provided inside the second steel structure box body 210; there is an installation gap between the second steel structure box body 210 and the bridge pier 600, and the buffer member 220 is arranged in the installation gap to dissipate the impact energy generated by external impacts. Exemplarily, one end of the buffer member 220 is connected to the outer surface of the bridge pier 600, and the other end is connected to the side wall of the second steel structure box body 210.

[0032] Exemplarily, the second floating energy dissipation mechanism 200 adopts a hollow second steel structure box body 210, and a support member 120 and a second energy dissipation filler part 132 are arranged inside it. This design ensures that the box body has stronger structural stability when bearing impacts, and can effectively absorb impact energy through the filled energy dissipation materials (such as aluminum foam, honeycomb structure materials or polymer buffer materials), reducing the direct transmission of the impact force. In addition, an installation gap is reserved between the second steel structure box body 210 and the pier 600, and a buffer member 220 (such as high-damping rubber or polyurethane foam, etc.) is arranged in this gap. When the ship impacts, the buffer member 220 can further absorb the remaining energy through elastic deformation, thereby reducing the intensity of the impact force directly acting on the pier 600 and enhancing the overall protection ability of the bridge. This multi-level energy consumption method effectively solves the problems of insufficient impact resistance and limited energy absorption of the anti-collision device in the prior art, gradually weakens the impact energy during the transmission process, prevents the pier 600 from being violently impacted, and improves the safety and durability of the bridge.

[0033] Exemplarily, the buffer member 220 is made of at least one of rubber, PE material or polytetrafluoroethylene material. Specifically, the rubber material has good elastic deformation ability and can significantly absorb and disperse impact energy when subjected to external impacts, thereby reducing the degree of energy directly transmitted to the pier 600 and improving the buffer performance of the device. The PE material has excellent weather resistance, impact resistance and low water absorption, enabling the buffer member 220 to maintain stable physical properties in the long-term underwater environment and avoiding the decline of the buffer effect caused by water erosion. The polytetrafluoroethylene material has an extremely low friction coefficient and excellent chemical corrosion resistance, enabling it to maintain a stable buffer effect in a high-frequency impact environment and effectively reducing the wear caused by friction, extending the service life of the buffer member 220. Generally speaking, the reasonable selection of these materials ensures that the buffer member 220 can provide stable and lasting energy dissipation effects under different environments and impact conditions, thereby enhancing the overall protection ability of the entire anti-collision device.

[0034] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 shown, the support member 120 includes a first support portion 121, a second support portion 122 and a third support portion 123. Among them, at least one group of the second support portions 122 is vertically arranged on the first support portion 121, and the second support portion 122 is connected to the inner wall of the first steel structure box body 110 or the second steel structure box body 210; one group of the third support portions 123 is respectively arranged at both ends of the first support portion 121, and the two groups of the third support portions 123 respectively extend obliquely in opposite directions, and the third support portion 123 is also connected to the inner wall of the first steel structure box body 110 or the second steel structure box body 210.

[0035] On this basis, the support member 120 is composed of a first support portion 121, a second support portion 122 and a third support portion 123, wherein the second support portion 122 is at least vertically arranged on the first support portion 121, and is connected to the inner wall of the first steel structure box 110 or the second steel structure box 210, thereby providing good vertical support in the force direction, so that the box can maintain structural stability when impacted, and avoid local deformation or instability. In addition, the third support portion 123 is respectively arranged at both ends of the first support portion 121, and extends obliquely in directions away from each other, and is also connected to the inner wall of the steel structure box. This support method forms a stable structure similar to a triangle, improves the bearing capacity, and evenly distributes the impact energy between the internal support members 120, reduces local stress concentration, and thus enhances the impact resistance of the entire device.

[0036] In actual operation, when a ship collides, the first support portion 121 bears the initial impact force, while the second support portion 122 provides additional vertical support to prevent the box from being drastically deformed after being subjected to force. At the same time, the inclined structure of the third support portion 123 can effectively disperse the impact energy, so that the impact force is transmitted in multiple directions, avoiding stress concentration in a single direction, and further improving the compressive resistance and stability of the anti-collision device. In addition, since each support portion is connected to the inner wall of the steel structure box, the entire support system can distribute the impact force more evenly to prevent the box from being broken or damaged due to excessive local force. Finally, this optimized design solves the problem in the prior art that the steel structure box is easily deformed or damaged under high-intensity impact, significantly improves the structural strength and impact resistance of the anti-collision device, and ensures that the device can maintain a stable protective effect during long-term use.

[0037] In some embodiments, in combination Figure 1 , Figure 2 as well as Figure 7 The connecting frame 300 includes a rib plate 310 and a rib plate 320. The rib plate 310 is vertically provided at both ends of the rib plate 320, and an installation gap is formed between the rib plate 310 and the rib plate 320. The installation gap is respectively provided on both sides of the rib plate 320. The first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 are respectively slidably provided in the installation gap. Exemplarily, the rib plate 320 is vertically connected to the center line of the plate surface of the rib plate 310, so that two rib plates 310 and one rib plate 320 form an I-shape, and the concave parts on both sides of the I-shape structure are the installation gaps. Furthermore, the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 are both slidably matched with the plate surface of the rib plate 310 on one side facing the installation gap.

[0038] Exemplarily, two sets of energy dissipating members 400 are respectively disposed in two installation gaps, and one end of the energy dissipating member 400 is connected to the rib plate 320, and the other end is connected to the first floating energy dissipation mechanism 100 or the second floating energy dissipation mechanism 200. The energy dissipating member 400 can be deformed and compressed along the impact direction under the condition of being externally impacted.

[0039] Exemplarily, in combination with Figure 1 、 Figure 2 and Figure 8 , the energy dissipating member 400 includes a first buffer section 410 and a second buffer section 420. A plurality of the first buffer sections 410 are sequentially and relatively bent, and adjacent two first buffer sections 410 are connected by one second buffer section 420, and a bending gap is formed between adjacent first buffer sections 410. Wherein, under the condition of being externally impacted, the first buffer section 410 can elastically deform towards the corresponding bending gap to dissipate the impact energy generated by the external impact. Further, the first buffer section 410 and the second buffer section 420 can be formed by welding steel plates.

[0040] On this basis, the combination of the rib plate 310 and the rib plate 320 makes the connecting frame 300 have higher stiffness and stability, ensuring that the floating energy dissipation mechanism can be effectively supported during the impact and preventing the overall structure from deforming and failing. Secondly, the first floating energy dissipation mechanism 100 and the second floating energy dissipation mechanism 200 can slide in the installation gap, and can achieve relative movement during the impact, avoiding structural damage caused by rigid collision, and effectively squeezing the energy dissipating member 400 to dissipate the impact energy during this process. In addition, the two sets of energy dissipating members 400 are respectively arranged in two installation gaps, and by connecting one end to the rib plate 320 and the other end to the floating energy dissipation mechanism, the energy dissipating member 400 can be deformed under force along the impact direction, thereby further absorbing the impact energy and reducing the damage to the structure.

[0041] At the same time, when being externally impacted, the first buffer section 410 will elastically deform towards the corresponding bending gap, thereby effectively absorbing and dissipating the impact energy, avoiding the instantaneous impact force directly acting on the floating energy dissipation mechanism or the bridge pier 600, and reducing the risk of structural damage. In addition, due to the bent design of the first buffer section 410, its deformation mode mainly depends on the bending and springback characteristics of the material. Compared with the traditional linear buffer structure, it can provide better energy absorption effect, and can still maintain good buffer performance after multiple impacts, improving the service life of the device. The addition of the second buffer section 420 ensures the stability of the entire buffer structure, prevents the buffer member 220 from being damaged due to local fatigue during long-term use, and further enhances the overall anti-impact ability.

[0042] In some embodiments, such as Figure 1 、 Figure 2As shown, at least one of the upper and lower outer wall surfaces of the first floating energy dissipation mechanism 100 is provided with a first energy dissipation baffle 111. A plurality of energy dissipation bolts 500 are threaded through between the first energy dissipation baffle 111 and the first floating energy dissipation mechanism 100, and the two are relatively fixed through the energy dissipation bolts 500. Further, the first energy dissipation baffle 111 is provided on the outer wall surface of the first steel structure box 110.

[0043] Exemplarily, the first energy dissipation baffle 111 is disposed opposite to the rib plate 310, and an impact gap is reserved therebetween. Wherein, in the case of an external impact, the first energy dissipation baffle 111 can move along the impact gap and abut against the rib plate 310 and break under the continuous action of the external impact to dissipate the impact energy generated by the external impact.

[0044] In some embodiments, such as Figure 1 , Figure 2 As shown, at least one of the upper and lower outer wall surfaces of the second floating energy dissipation mechanism 200 is provided with a second energy dissipation baffle 211. A plurality of energy dissipation bolts 500 are threaded through between the second energy dissipation baffle 211 and the second floating energy dissipation mechanism 200, and the two are relatively fixed through the energy dissipation bolts 500; further, the second energy dissipation baffle 211 is provided on the outer wall surface of the second steel structure box 210.

[0045] Exemplarily, the second energy dissipation baffle 211 is disposed opposite to the rib plate 310, and an impact gap is reserved therebetween. Wherein, in the case of an external impact, the rib plate 310 can move along the impact gap and abut against the second energy dissipation baffle 211, and break the second energy dissipation baffle 211 under the continuous action of the external impact to dissipate the impact energy generated by the external impact.

[0046] On this basis, when an external impact occurs, the first energy dissipation baffle 111 will move along the impact gap and gradually abut against the rib plate 310, and break under the continuous impact, thereby effectively dissipating the impact energy. Similarly, the rib plate 310 will continue to move along another impact gap and gradually abut against the second energy dissipation baffle 211, so that the second energy dissipation baffle 211 breaks under the impact of the rib plate 310 to dissipate the impact energy. This structural design ensures that under different impact intensities, the anti-collision device can deform and break according to the preset energy absorption path, avoiding the direct transmission of impact energy to the main structure, thereby reducing the risk of structural damage.

[0047] Secondly, both the first energy dissipation baffle 111 and the second energy dissipation baffle 211 are fixed by energy dissipation bolts 500, enabling the assembly to absorb part of the energy first when subjected to impact and further dissipate energy through deformation and breakage. Compared with the traditional rigid anti-collision structure, this multi-stage buffering mode can more effectively disperse the impact load and reduce the damage of the instantaneous impact force to the structure. At the same time, the reserved impact gap ensures that the baffle has a certain movement space when the impact occurs, enabling it to gradually absorb the impact energy instead of instantly bearing all the impact force, improving the stability of the overall structure. In addition, this design also has a certain degree of maintainability. After the energy dissipation baffle is damaged, the function of the anti-collision device can be restored by replacing the energy dissipation bolts 500, the first energy dissipation baffle 111, and the second energy dissipation baffle 211, reducing the maintenance cost and increasing the service life.

[0048] Exemplarily, in combination with Figure 2 、 Figure 9 、 Figure 10 and Figure 11 , the impact energy dissipation of the multi-stage energy-consuming self-floating ship anti-collision device of the present application can be divided into the following three stages. It should be noted that in Figure 9 、 Figure 10 and Figure 11 , the arrow on the left indicates the impact direction: In the first stage, when the ship impacts the multi-stage energy-consuming self-floating ship anti-collision device, it first acts on the collision-facing surface of the first floating energy dissipation mechanism 100. Since the stiffness of the first floating energy dissipation mechanism 100 is relatively large, in the initial stage, the deformation of the energy-consuming member 400 is mainly relied on to absorb energy. Specifically, the first floating energy dissipation mechanism 100 deflects inward under the action of the impact force, causing the first group of energy-consuming members 400 to be compressed and deformed, thereby dissipating part of the impact energy. At the same time, since the first energy dissipation baffle 111 is connected to the first floating energy dissipation mechanism 100 by the energy dissipation bolt 500, under the continuous action of the impact force, the energy dissipation bolt 500 is cut off and the first energy dissipation baffle 111 falls off, and this process further absorbs the impact energy. Meanwhile, the non-collision-facing surface and the side surface of the ship anti-collision device drive the energy-consuming member 400 to undergo elongation deformation due to the displacement of the first floating energy dissipation mechanism 100, and also dissipate a part of the impact energy synchronously.

[0049] In the second stage, when the energy dissipation bolts 500 are sheared and the first energy dissipation baffle 111 falls off, the impact force continues to act on the first floating energy dissipation mechanism 100, causing it to further deflect inward. At this time, the energy dissipation components 400 of the first group and the energy dissipation components 400 of the second group are synchronously compressed, and the compression displacement of the energy dissipation components 400 of the first group is greater than that of the energy dissipation components 400 of the second group. Meanwhile, the rib plate 310 of the connecting frame 300 abuts against the second energy dissipation baffle 211, further reducing the impact energy. When the impact force reaches a certain level, the energy dissipation bolts 500 on the second energy dissipation baffle 211 are sheared, and the second energy dissipation baffle 211 falls off, releasing an additional energy dissipation mechanism. Throughout the process, the back collision surface of the first floating energy dissipation mechanism 100 and the energy dissipation components 400 on both sides continue to deform, enhancing the dissipation effect of the impact energy.

[0050] In the third stage, after the first energy dissipation baffle 111 and the second energy dissipation baffle 211 fall off, the impact energy continues to impact the ship collision prevention device, and the first energy dissipation device and the second energy dissipation device continue to compress until the maximum compression displacement is reached and no further compression is possible. The energy dissipation devices on the back collision surface and the side surfaces continue to elongate, and part of the impact energy is dissipated due to the deformation of the energy dissipation devices.

[0051] When the energy dissipation components 400 of the first group and the energy dissipation components 400 of the second group are compressed to the extreme displacement, the energy that has not been dissipated yet continues to move the ship collision prevention device. At this time, the entire ship collision prevention device begins to impact the pier 600. Due to the action in the previous stages, most of the impact energy of the ship has been dissipated, and the energy continuing to impact the pier 600 is only a very small part of the initial energy. The buffer member 220 provided between the self-floating ship collision prevention device and the pier 600 can still dissipate part of the energy. At this time, the impact energy acting on the pier 600 is very small, thus better protecting the pier 600.
