When the anti-collision floating box body is impacted from outside, the front fixedly connected steel plate can preliminarily bear the impact and disperse stress, the impact force is transmitted to the buffer pipe through the inside of the anti-collision floating box body, the piston in the buffer pipe slides in the axial direction under the action of air pressure and compresses the reset spring, so that the instantaneous energy generated by the impact is effectively absorbed, and the risk of structure deformation or damage of the anti-collision floating box body is reduced.

Description

Technical Field

[0001] This invention relates to the field of anti-collision buoy technology, and in particular to a series-connected floating steel-clad anti-collision buoy. Background Technology

[0002] With the increasing number of port terminals, waterways, bridge piers and near-shore engineering facilities, in order to prevent ships, floating objects or water equipment from colliding with fixed structures during navigation, berthing and wind and waves, anti-collision buoys or floating protective devices are usually installed in relevant waters to buffer the impact and reduce damage.

[0003] In practice, some problems still exist: Existing anti-collision floating boxes mostly adopt hollow structures or are filled with floating materials. They achieve basic anti-collision functions through their own buoyancy and structural rigidity. Their surfaces are usually covered with rubber layers, plastic layers, or steel plates to improve wear resistance and impact resistance, so as to adapt to long-term aquatic use environments. However, existing anti-collision pontoons still have certain shortcomings in practical applications. On the one hand, most anti-collision pontoons rely solely on their own buoyancy or material elasticity to passively reset after being impacted, with limited buffering range and energy absorption capacity. When subjected to large or repeated impacts, they are prone to local structural deformation, buoyancy reduction, or even failure, making it difficult to reflect the extent of damage in a timely manner. On the other hand, existing anti-collision pontoons usually lack intuitive indication and early warning functions for the stress state. When inspecting, managers can often only judge whether there is obvious damage by appearance, and cannot accurately grasp whether the internal structure has been affected by the cumulative impact, which can easily cause potential safety hazards. Furthermore, when multiple sets of anti-collision pontoons are needed to form a protective belt, existing technologies mostly use rigid connections or simple rope connections, which are not stable enough and have insufficient buffering coordination. Moreover, the disassembly and assembly process is complicated and the construction efficiency is low when maintaining or replacing individual pontoons, which is not conducive to the rapid deployment and flexible adjustment of anti-collision pontoons.

The connecting mechanism includes a flexible connector, a first connecting plate, a second connecting plate, a hook, and a U-shaped screw. The two first connecting plates are respectively fixedly connected to the two side walls of the anti-collision floating box body, and the two second connecting plates are respectively fixedly connected to the two side walls of the flexible connector. Hooks are fixedly connected to the outer sides of the two second connecting plates, and the middle parts of the two U-shaped screws are respectively engaged with the inner side of the hooks.

[0007] Preferably, a steel plate is fixedly connected to the front of the anti-collision floating box body, a support plate is fixedly connected to the top of the buffer tube, and the bottom of the transmission plate is slidably connected to the top of the support plate.

[0008] Preferably, a limiting plate is fixedly connected to one side of the top of the support plate, and the press-type trigger alarm is fixedly connected to the inner side of the limiting plate.

[0009] Preferably, two extrusion blocks are slidably connected to the middle of the support plate, and an indicator plate is fixedly connected to the outer side of each of the two extrusion blocks, and a fixing plate is fixedly connected to the inner side of each of the two indicator plates.

[0010] Preferably, two pull-back spring rods are fixedly connected to the side wall of the support plate, and the free ends of the two pull-back spring rods are respectively fixedly connected to the inner side of the two fixed plates.

[0011] Preferably, a marking plate and a scale plate are fixedly connected to one side of the top of the support plate, and a fixing rod is fixedly connected to the outside of the transmission plate.

[0012] Preferably, a marking pen is fixedly connected to the bottom end of the fixing rod, the bottom end of the marking pen is attached to the top end of the marking plate, and a vertical plate is fixedly connected to the other side of the top end of the buffer tube.

[0013] Preferably, a rotating shaft is fixedly connected to the outer side of the two first connecting plates, and a locking handle is rotatably connected to the outer side of each of the two rotating shafts.

[0014] Preferably, the two U-shaped screws pass through the two locking handles respectively, and one end of each of the two U-shaped screws is threaded with a nut.

[0015] (III) Beneficial Effects The beneficial effects of this invention are: 1. This invention, by setting a buffer warning mechanism on the back of the anti-collision pontoon body, enables the anti-collision pontoon body to not only have basic floating anti-collision capabilities during actual use, but also to buffer and adjust the stress state and provide intuitive feedback. When the anti-collision pontoon body is subjected to external impact, the steel plate fixedly connected to the front can initially bear the impact and disperse the stress. The impact force is transmitted to the buffer tube through the inside of the anti-collision pontoon body. The piston in the buffer tube slides axially under the action of air pressure and compresses the return spring, thereby effectively absorbing the instantaneous energy generated by the impact and reducing the risk of structural deformation or damage to the anti-collision pontoon body. At the same time, the piston drives the transmission plate to move through the connecting rod, so that the threaded cylinder, adjusting rod and squeezing rod are linked, thereby realizing the controllable output of the buffering process. This allows the anti-collision pontoon body to maintain good structural stability and return capability under multiple impact conditions, improves the overall service life and protection reliability, and avoids the failure of the anti-collision pontoon body due to single or cumulative impacts.

[0016] 2. By setting up a coordinated structure among the compression block, indicator plate, fixed plate, pull-back spring rod, upright plate, scale plate, fixed rod, and marker pen, the buffer warning mechanism can not only perform the function of buffering and absorbing energy, but also provide graded indication and recording of the stress state of the anti-collision pontoon body. During daily inspections, users can intuitively judge the current warning level of the anti-collision pontoon body by observing the changes in the distance between the two indicator plates and the upright plate, thereby deciding whether to carry out maintenance or preventive maintenance. When the compression rod presses against the push-to-trigger alarm, it can clearly indicate that the anti-collision pontoon body has been subjected to a large impact and requires forced maintenance. At the same time, during the displacement of the transmission plate, the marker pen leaves a mark on the marking plate through the fixed rod. Combined with the scale plate, it can accurately reflect the force stroke and impact degree, realize the traceability judgment of the force process, avoid maintenance decisions based solely on experience, and improve the scientificity and safety of the operation and management of the anti-collision pontoon.

[0017] 3. This invention features a connecting mechanism on both sides of the anti-collision pontoon body. Through the cooperation of flexible connectors, a first connecting plate, a second connecting plate, hooks, U-shaped screws, rotating shafts, and locking handles, multiple anti-collision pontoon bodies can be quickly installed in series or disassembled individually. While ensuring connection strength and overall stability, it significantly improves construction and maintenance efficiency. The flexible connectors allow for a certain amount of movement between the anti-collision pontoon bodies, preventing stress concentration on rigid connections due to water flow, surges, or ship impacts, thus reducing the probability of damage to the connection parts. The structure of the U-shaped screw and nut with the locking handle facilitates rapid operation on water or in narrow environments, reducing labor and time costs. This allows the series-connected floating steel-clad anti-collision pontoon to simultaneously possess excellent anti-collision performance, early warning function, and engineering adaptability in practical applications, enhancing its overall practical value.

[0020] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please refer to Figures 1 to 7 As shown, a series-connected floating steel-clad anti-collision pontoon of the present invention includes an anti-collision pontoon body 2, with connecting mechanisms 4 on both sides of the anti-collision pontoon body 2 and a buffer warning mechanism 5 on the back of the anti-collision pontoon body 2. The buffer warning mechanism 5 includes a buffer tube 501, a return spring 509, a connecting rod 502, a transmission plate 503, a threaded cylinder 512, an adjusting rod 513, a pressing rod 514, and a push-type trigger alarm 515. A piston 518 is slidably connected to the inner wall of the buffer tube 501. A return spring 509 is fixedly connected to the inner side of the piston 518. A connecting rod 502 is fixedly connected to the inner side of the piston 518. One end of the connecting rod 502 passes through the buffer tube 501 and is fixedly connected to the transmission plate 503. A threaded cylinder 512 is rotatably connected to the inner side of the transmission plate 503. An adjusting rod 513 is threadedly connected to the inner side of the threaded cylinder 512. A pressing rod 514 is fixedly connected to one end of the adjusting rod 513. One end of the pressing rod 514 is placed outside the push-type trigger alarm 515. The connecting mechanism 4 includes a flexible connector 401, a first connecting plate 402, a second connecting plate 403, a hook 404, and a U-shaped screw 405. The two first connecting plates 402 are respectively fixedly connected to the two side walls of the anti-collision floating box body 2, and the two second connecting plates 403 are respectively fixedly connected to the two side walls of the flexible connector 401. The hooks 404 are fixedly connected to the outer sides of the two second connecting plates 403, and the middle parts of the two U-shaped screws 405 are respectively engaged with the inner side of the hooks 404. In actual implementation, the anti-collision buoy body 2 floats on the water surface by its own buoyancy. When a ship or floating object approaches, the anti-collision buoy body 2 plays the first line of protection. The impact force is transmitted from the back of the anti-collision buoy body 2 to the buffer warning mechanism 5. The buffer warning mechanism 5 absorbs and disperses the impact energy step by step through its internal structure. At the same time, the connecting mechanism 4 set on both sides of the anti-collision buoy body 2 enables multiple anti-collision buoy bodies 2 to form a series structure. When impacted, adjacent anti-collision buoy bodies 2 can generate a linkage buffering effect, thereby reducing the force concentration of a single anti-collision buoy body 2 and improving the overall anti-collision stability and safety of use.

[0022] Optionally, one end of the return spring 509 is fixedly connected to the inner wall of the buffer tube 501, and a sealing plug 3 is connected to the top of the anti-collision buoy body 2. The buffer tube 501 is fixedly connected to the back of the anti-collision buoy body 2 and communicates with the interior of the anti-collision buoy body 2. In actual implementation, when the anti-collision buoy body 2 is impacted, the air inside it is compressed through the buffer tube 501 connected to the anti-collision buoy body 2. The piston 518 inside the buffer tube 501 slides along the inner wall under the action of air pressure and pushes the return spring 509 to undergo elastic deformation. The return spring 509 temporarily stores the impact energy during the compression process. When the external impact disappears, the return spring 509 releases its elastic force to push the piston 518 to reset, so that the air in the buffer tube 501 flows back into the interior of the anti-collision buoy body 2. With the sealing effect of the sealing plug 3, the continuity of the buffering process and the stability of the reset process are ensured.

[0023] Optionally, a steel plate 1 is fixedly connected to the front of the anti-collision pontoon body 2, a support plate 519 is fixedly connected to the top of the buffer tube 501, and the bottom end of the transmission plate 503 is slidably connected to the top of the support plate 519. In actual implementation, during the anti-collision process, the steel plate 1 on the front of the anti-collision pontoon body 2 first bears the external impact and plays the role of dispersing stress. The steel plate 1 evenly transmits the impact force to the interior of the anti-collision pontoon body 2 structure. The buffer tube 501 forms a stable mounting base through the fixedly connected support plate 519. The transmission plate 503 slides along the top of the support plate 519 under the drive of the connecting rod 502, so that the internal components of the buffer warning mechanism 5 can move in coordination according to the preset path, thereby converting the impact borne by the anti-collision pontoon body 2 into a controllable linear displacement and avoiding sudden stress on the structure.

[0024] Optionally, a limiting plate 516 is fixedly connected to one side of the top of the support plate 519, and a push-to-trigger alarm 515 is fixedly connected to the inner side of the limiting plate 516. In actual implementation, as the transmission plate 503 slides on the support plate 519, the displacement direction of the transmission plate 503 is constrained by the limiting plate 516, so that the transmission plate 503 always moves in the set direction, avoiding deviation or jamming. When the displacement of the transmission plate 503 reaches the set threshold, the pressing rod 514 gradually approaches and eventually triggers the push-to-trigger alarm 515 fixed to the inner side of the limiting plate 516, thereby generating a warning signal in time when the anti-collision floating box body 2 is subjected to a large impact, so that the user can quickly identify abnormal working conditions and take corresponding maintenance measures.

[0025] Optionally, two compression blocks 510 are slidably connected to the middle of the support plate 519. Indicator plates 508 are fixedly connected to the outer sides of each compression block 510, and fixing plates 511 are fixedly connected to the inner sides of each indicator plate 508. In actual implementation, during the operation of the buffer warning mechanism 5, the two compression blocks 510 slidably connected to the middle of the support plate 519 move synchronously under the linkage of the transmission plate 503. The compression blocks 510 drive the indicator plates 508 to displacement through the fixed plates 511. The movement distance of the indicator plates 508 can intuitively reflect the current stress state of the anti-collision pontoon body 2. During inspection, users can judge the working degree of the buffer warning mechanism 5 by observing the relative position changes of the two indicator plates 508, thereby achieving visual monitoring of the operating status of the anti-collision pontoon body 2.

[0026] Optionally, two pull-back spring rods 520 are fixedly connected to the side wall of the support plate 519, and the free ends of the two pull-back spring rods 520 are respectively fixedly connected to the inner side of the two fixed plates 511. In actual implementation, when the external impact weakens or disappears, the pull-back spring rods 520 exert traction on the fixed plates 511 under the action of elasticity, causing the compression block 510 to gradually return to its initial position. During the resetting process of the compression block 510, the indicator plate 508 is driven to return to its original position synchronously, thereby avoiding the influence of subsequent judgments due to the indicator state remaining in the offset position for a long time after an impact. Through the setting of the pull-back spring rods 520, the buffer warning mechanism 5 has an automatic reset capability, ensuring the accuracy and stability of the indication during multiple uses.

[0027] Optionally, a marking plate 506 and a scale plate 507 are fixedly connected to one side of the top of the support plate 519, and a fixing rod 504 is fixedly connected to the outside of the transmission plate 503. In actual implementation, when the transmission plate 503 is displaced, the fixing rod 504 fixedly connected to the outside of the transmission plate 503 moves synchronously. The displacement of the fixing rod 504 corresponds to the stroke of the piston 518 in the buffer tube 501. Users can intuitively read the impact displacement data by observing the positional change of the fixing rod 504 relative to the scale plate 507. The cooperative arrangement of the marking plate 506 and the scale plate 507 transforms the buffering process from an invisible state to a quantifiable display state, facilitating later maintenance analysis and operation record management.

[0028] Optionally, a marker pen 505 is fixedly connected to the bottom end of the fixing rod 504, and the bottom end of the marker pen 505 is attached to the top end of the marking plate 506. A vertical plate 517 is fixedly connected to the other side of the top end of the buffer tube 501. In actual implementation, when the fixing rod 504 moves with the transmission plate 503, the marker pen 505 fixedly connected to its bottom end leaves a mark on the top end of the marking plate 506. The length of the mark recorded by the marker pen 505 can reflect the maximum displacement of the anti-collision buoy body 2 in one or more impacts. Together with the vertical plate 517, it forms a stable reference benchmark, so that the marking process is not affected by water surface swaying, thereby providing users with a reliable force recording basis, which facilitates the determination of whether the anti-collision buoy body 2 needs to be replaced or reinforced for maintenance.

[0029] Optionally, a rotating shaft 407 is fixedly connected to the outer side of the two first connecting plates 402, and a locking handle 406 is rotatably connected to the outer side of each of the two rotating shafts 407. In actual implementation, when multiple anti-collision pontoon bodies 2 are installed in series, the rotating shaft 407 on the outer side of the first connecting plate 402 provides a rotation fulcrum for the locking handle 406. The user can quickly complete the connection or release operation by rotating the locking handle 406, so that the connection mechanism 4 has good operational convenience while ensuring connection strength. When the anti-collision pontoon body 2 undergoes relative displacement under the action of water flow or impact, the rotating shaft 407 structure can release some torsional stress and reduce the risk of damage to the connection parts.

[0030] Optionally, two U-shaped screws 405 pass through two locking handles 406 respectively, and one end of each U-shaped screw 405 is threaded with a nut 408. In actual implementation, after the U-shaped screws 405 pass through the locking handles 406, they are tightened by the nuts 408, so that the hooks 404 and U-shaped screws 405 form a reliable locking structure. In the series connection state, multiple anti-collision buoy bodies 2 can maintain a stable connection. When it is necessary to inspect or replace a single anti-collision buoy body 2, the disassembly operation can be completed by simply loosening the nuts 408, avoiding the complexity of construction caused by overall disassembly, thereby improving the maintenance efficiency and adaptability of the anti-collision buoy system in actual aquatic environments.

[0031] Working Principle: In practical use, the tandem floating steel-clad anti-collision pontoon of this invention provides basic buoyancy support and anti-collision bearing function through the pontoon body 2. The steel plate 1 on the front of the pontoon body 2 initially absorbs the impact force when a ship or floating object collides with it, transmitting the impact force into the interior of the pontoon body 2. The air inside the pontoon body 2, after being compressed, is guided and buffered through the connected buffer pipe 501, thereby preventing the instantaneous impact force from concentrating on the structure of the pontoon body 2 itself and improving overall impact resistance and stability. When an impact force is applied to the back area of ​​the anti-collision pontoon body 2, the piston 518 inside the buffer tube 501 slides along the axial direction of the buffer tube 501 under the action of air pressure. The piston 518 pushes the return spring 509 fixedly connected inside to compress. The return spring 509 stores the impact energy during the compression process. At the same time, the piston 518 drives the transmission plate 503 to move through the connecting rod 502, so that the anti-collision pontoon body 2 forms a controllable buffer stroke during the force process, thereby reducing the risk of structural damage to the steel plate 1 and the anti-collision pontoon body 2. As the transmission plate 503 shifts, the threaded cylinder 512 rotatably connected to the inner side of the transmission plate 503 drives the adjusting rod 513 rotatably connected to its inner side to move axially in a relative rotational state. The adjusting rod 513 further pushes the pressing rod 514 fixedly connected to one end to move outward. During the displacement process, the pressing rod 514 gradually approaches and finally presses the push-type trigger alarm 515. When the pressing rod 514 has not yet contacted the push-type trigger alarm 515, it indicates that the impact borne by the anti-collision floating box body 2 is within the buffer range. At this time, during the inspection, the user can make a preliminary judgment by observing the displacement state of the two pressing blocks 510 slidably connected in the middle of the support plate 519. After being affected by the linkage of the transmission plate 503, the pressing block 510 drives the indicator plate 508 fixedly connected to its outer side to move synchronously. The change in the distance between the indicator plate 508 and the upright plate 517 can be used as a direct reference for the current force and warning level. The user can judge whether routine inspection or preventive maintenance is required based on the size of the distance between the two indicator plates 508 and the upright plate 517. When the anti-collision pontoon body 2 suffers a large impact, the displacement amplitude of the piston 518 in the buffer tube 501 increases, the return spring 509 is further compressed, the connecting rod 502 drives the transmission plate 503 to produce a large stroke displacement, and the adjusting rod 513 pushes the squeezing rod 514 to finally squeeze the push-type trigger alarm 515. At this time, the push-type trigger alarm 515 is triggered, indicating that the anti-collision pontoon body 2 has suffered relatively serious impact damage and needs to be forcibly repaired or replaced to prevent the hidden danger from continuing to expand. At the same time, during the displacement of the transmission plate 503, the fixed rod 504 fixedly connected to the outside of the transmission plate 503 moves synchronously. The marker pen 505 fixedly connected to the bottom end of the fixed rod 504 leaves continuous or intermittent marks on the top of the marking plate 506. The user can read the length of the mark left by the marker pen 505 on the marking plate 506 by combining the displacement scale marked on the scale plate 507, so as to further judge the cumulative impact of the anti-collision pontoon body 2 in different time periods and provide a reliable basis for subsequent maintenance decisions. After the impact disappears, the return spring 509 pushes the piston 518 to return to its original position along the buffer tube 501 under its own elastic force. The piston 518 drives the transmission plate 503, threaded cylinder 512, adjusting rod 513 and pressing rod 514 to gradually return to their initial positions through the connecting rod 502. The pressing block 510 returns to its original position synchronously under the traction of the pull-back spring rod 520, so that the indicator plate 508 returns to its initial reference position, thereby ensuring the accuracy of the next inspection and judgment. Through the connecting mechanism 4 set on both sides of the anti-collision pontoon body 2, the user can realize the quick connection or disassembly of multiple anti-collision pontoon bodies 2 by means of the cooperation between the flexible connector 401, the first connecting plate 402, the second connecting plate 403, the hook 404 and the U-shaped screw 405. With the structural setting of the rotating shaft 407 and the locking handle 406, the installation and maintenance efficiency can be improved while ensuring the connection stability. This makes the series floating steel-coated anti-collision pontoon have the comprehensive functions of buffer protection, status warning, recording and judgment and quick connection in actual water anti-collision applications.
