Description

Technical Field

[0001] This invention belongs to the field of coastal protection equipment technology, and in particular relates to an energy-absorbing device for a coastal protection breast wall. Background Technology

[0002] A breakwater breast wall is a traditional structure used in port engineering and coastal protection, specifically referring to the vertical wall structure built on the seaward side of the breakwater crest. Its main function is to prevent waves from crossing the breakwater crest and to protect the area behind the breakwater or the harbor waters.

[0003] When waves crash against a breakwater, seawater may overflow the top of the breakwater. As the last line of defense, the breast wall can significantly reduce the influx of seawater into the harbor or the land behind it, preventing the flooding of dock operations, roads, and equipment. The breast wall's own weight and wave resistance can help stabilize the breakwater structure and resist the overturning force of waves. However, traditional breast walls are usually constructed with reinforced concrete, and their design concept focuses on "rigid resistance," relying on the wall's own mass and strength to withstand the kinetic energy of waves. Although this method is effective under normal working conditions, when facing strong typhoons, abnormal storm surges, or extreme weather, the wall may suffer structural fatigue, cracks, or even destruction, posing safety risks to its reliability and durability. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose an energy-absorbing device for coastal protection breast walls, which solves the problems of traditional breast wall structures in the face of strong wave impacts, such as stress concentration, rapid structural damage, and insufficient impact resistance, which rely solely on their own rigidity to resist the impact and lack an energy dissipation mechanism.

[0005] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0006] An energy-absorbing device for a coastal protection breast wall includes: a base and an energy-absorbing mechanism mounted on the base;

[0007] The base includes a fixed base plate and a column. The energy absorption mechanism includes a suspension component, a blocking component, and a reset energy absorption assembly. One end of the suspension component is hinged to the column, and a blocking component is installed at the end of the suspension component facing away from the column. One end of the reset energy absorption assembly is hinged to the lower surface of the suspension component, and the other end is hinged to the upper surface of the base plate. The reset energy absorption assembly is configured as an elastic structure that can retract and reset along its own length direction to absorb the impact force of ocean waves.

[0008] Furthermore, the reset energy absorption assembly includes a sleeve, a telescopic rod, a reset spring, and a hinge. The lower surface of the suspension component and the upper surface of the base plate are both fixedly connected to hinge joints corresponding to the hinges. There are two hinges, which are respectively connected to the sleeve and the telescopic rod. The sleeve has a receiving cavity for accommodating the reset spring and part of the telescopic rod. One end of the reset spring is connected to the bottom surface of the receiving cavity, and the other end is connected to the telescopic rod.

[0009] Furthermore, the reset energy absorption assembly also includes a guide rod, which is fixedly connected to the telescopic rod. The sleeve is provided with a guide groove, which communicates with the receiving cavity. The guide rod is slidably connected within the guide groove.

[0010] Furthermore, it also includes two suspension components, which are disposed between the reset energy absorption components.

[0011] The suspension assembly includes a suspension block, a suspension rope, a guide block, and a fixing block. The fixing block is fixed to the upper surface of the base plate. One end of the suspension rope is connected to the suspension block, and the other end is connected to the fixing block. The guide block is fixed to the side wall of the suspension component and has a guide cavity inside. A support guide rod is fixed inside the guide cavity. The suspension rope passes through the guide cavity and overlaps the support guide rod.

[0012] Furthermore, the suspension assembly includes a connecting plate, a limiting spring, a limiting base, and a locking block. The end of the suspension block facing away from the suspension rope is fixedly connected to the connecting plate. The limiting base is fixedly connected to the upper surface of the base plate. The end of the limiting base facing away from the base plate is connected to the locking block through the limiting spring. The locking block has a slot for receiving the connecting plate. The connecting plate and the locking block are detachably connected.

[0013] Furthermore, the suspension component has a hollow cavity and includes a hinge section and a suspension section. One end of the hinge section is hinged to the column, and the other end is fixed to the suspension section. The end of the suspension section opposite to the hinge section is provided with a mounting member for installing the blocking component.

[0014] Furthermore, the mounting component has an inter-connected embedding groove and an embedding through groove, the abutment includes a fixedly connected plug section and a guide section, the plug section is provided with a plug screw, the embedding groove is used for the plug section to be embedded, and when the plug section is embedded into the embedding groove, part of the plug screw is located in the embedding through groove, and the guide section has a receiving port.

[0015] Furthermore, it also includes a fixing plate, which is fixed to the upper end of the plug-in section. The upper surface of the suspension section is provided with a fixing screw, and the fixing plate is provided with a through hole for the fixing screw to pass through.

[0016] Furthermore, the suspended segment has connecting ear plates on both sides of its opposite side walls along its width direction.

[0017] Through the aforementioned technical solution, by setting up a base including a bottom plate and columns, a swingable suspension component, a stopper installed at one end of the suspension component, and a retractable and resetting energy-absorbing assembly, an effective buffering and energy-absorbing function against wave impact is achieved. Specifically, when a wave hits the stopper, the impact force causes the suspension component to swing, simultaneously deforming the resetting energy-absorbing assembly. This converts some kinetic energy into elastic potential energy, storing it in the resetting energy-absorbing assembly, significantly reducing the direct force of the wave on the base. Subsequently, after the wave recedes, the resetting energy-absorbing assembly releases its elastic potential energy, causing the suspension component to reset. In essence, the energy-absorbing mechanism effectively overcomes the limitations of traditional breast walls that rely on rigid structures to resist impacts. This not only improves the overall impact resistance and service life of the base but also reduces localized scouring and wave reflection, enhancing the operational safety of the port area.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] In a specific embodiment provided in this disclosure, an energy-absorbing device for a coastal protection breast wall is provided, with reference to... Figures 1 to 7 As shown, the energy-absorbing device includes a base 1 and an energy-absorbing mechanism mounted on the base 1. The base 1 includes a fixed base plate 101 and a column 102. The energy-absorbing mechanism includes a suspension component 2, a stop component 3, and a reset energy-absorbing assembly 4. One end of the suspension component 2 is hinged to the column 102, and the stop component 3 is installed at the end of the suspension component 2 away from the column 102. One end of the reset energy-absorbing assembly 4 is hinged to the lower surface of the suspension component 2, and the other end is hinged to the upper surface of the base plate 101. The reset energy-absorbing assembly 4 is configured as an elastic structure that can retract and reset along its own length direction to absorb the impact force of sea waves.

[0033] Through the above technical solution, by setting up a base 1 including a base plate 101 and a column 102, a swingable suspension component 2, a stop component 3 installed at one end of the suspension component 2, and a retractable and resetting energy-absorbing component 4, an effective buffering and energy-absorbing function against wave impact is achieved. That is, when a wave hits the stop component 3, the impact force generated by the wave causes the suspension component 2 to swing, which in turn causes the resetting energy-absorbing component 4 to deform, thereby converting some of the kinetic energy into elastic potential energy and storing it in the resetting energy-absorbing component 4, significantly reducing the direct force of the wave on the base 1. Subsequently, after the wave recedes, the resetting energy-absorbing component 4 releases the elastic potential energy, which can cause the suspension component 2 to reset. Specifically, through the energy-absorbing mechanism, the limitations of traditional breast walls that rely on rigid structures to resist impact are effectively compensated for. This not only improves the overall impact resistance and service life of the base 1, but also reduces local scouring and wave reflection, enhancing the operational safety of the port area.

[0034] In some embodiments not shown, the reset energy absorption assembly 4 may include a hydraulic cylinder, a sliding piston, and two hinges 404. The hydraulic cylinder is fixedly mounted on the upper surface of the base plate 101 and is filled with damping oil. One end of the piston rod extends out of the hydraulic cylinder and connects to the lower surface of the suspension component 2, forming a wave force transmission path. The piston is provided with a throttling orifice or a bidirectional flow resistance plate to control the flow rate of the damping oil and provide adjustable buffer resistance. The elastic reset chamber is located at the tail of the piston and is filled with air or an elastomer. After the piston moves, it provides a reverse thrust to achieve reset. The two ends of the hydraulic cylinder are connected to the suspension component 2 and the base plate 101 through the hinges 404 to ensure the angular adaptability and sliding stability of the mechanism during movement.

[0035] In some implementations, reference Figure 1 and Figure 4 As shown, the reset energy-absorbing assembly 4 includes a sleeve 401, a telescopic rod 402, a reset spring 403, and two hinges 404, thus forming a buffer structure with axial telescopicity, sensitive response, and reliable reset. When a wave impacts the deflector 3 and drives the suspension component 2 to lift away from the column 102, the telescopic rod 402 slides axially relative to the sleeve 401 under the action of the hinge, simultaneously causing the reset spring 403 to undergo tensile deformation, effectively absorbing the kinetic energy generated by the wave impact. Specifically, one end of the reset spring 403 is fixed to the bottom surface of the housing cavity 4011 of the sleeve 401, and the other end is connected to the telescopic rod 402, ensuring the axial controlled deformation of the spring during the force process. As the wave thrust weakens, the suspension component 2 gradually falls back to its original position under the action of the spring's restoring force, and the telescopic rod 402 is pulled back to its initial position, completing the self-reset process, thereby realizing dynamic buffering and energy dissipation of the impact load.

[0036] The reset energy absorption component 4 not only improves the adaptability of the energy absorption device to complex wave conditions, but also ensures the guidance and structural stability of the reset energy absorption component 4 during movement through the cooperation of the double hinge 404 and the hinge joint 5, further enhancing the safety and service life of the entire base 1 under strong wave conditions.

[0037] In some implementations, reference Figure 1 and Figure 4As shown, the reset energy absorption assembly 4 also includes a guide rod 405, which is fixedly connected to the telescopic rod 402. A guide groove 4012 is provided on the sleeve 401, communicating with the receiving cavity 4011. The guide rod 405 is slidably connected within the guide groove 4012. The guide rod 405, in conjunction with the guide groove 4012, ensures that the reciprocating motion of the telescopic rod 402 during wave impact remains within a preset linear path, effectively preventing lateral swaying, offset, or twisting—non-ideal deformation behaviors—and enhancing the operation of the reset energy absorption assembly 4. The guiding and structural stability are improved. Specifically, when the wave impacts the suspension component 2 and lifts the end away from the column 102, the telescopic rod 402 drives the guide rod 405 to slide outward in the through groove, while the return spring 403 undergoes tensile deformation. When the impact force dissipates, the suspension component 2 falls back under the action of the spring, and the guide rod 405 also smoothly returns to its position with the telescopic rod 402. The trajectory of the entire energy absorption process is more controllable, which improves the service life and reliability of the energy absorption component, optimizes the response consistency and safety of the energy absorption mechanism to continuous wave impact, and is suitable for more complex and variable coastal working conditions.

[0038] In some implementations, reference Figure 1 , Figure 6 and Figure 7 As shown, the energy-absorbing device also includes two suspension components 6 disposed between the reset energy-absorbing components 4. Each suspension component 6 includes a suspension block 601, a suspension rope 602, a guide block 603, and a fixing block 604. The fixing block 604 is fixed to the upper surface of the base plate 101 and serves as the anchoring end of the suspension rope 602. One end of the suspension rope 602 is connected to the suspension block 601, and the other end is connected to the fixing block 604 after overlapping the support guide rod 6032 through the guide cavity 6031. The guide block 603 is fixed to the side wall of the suspension component 2. When the wave impact causes the suspension component 2 to oscillate, the suspension assembly 6 can work in conjunction with the reset energy absorption assembly 4 to provide support and cable limiting. That is, when the suspension component 2 is lifted away from the column 102, the suspension rope 602 is tightened by force, the suspension block 601 moves upward, and the movement of the suspension rope 602 in the guide cavity 6031 is limited and guided by the support guide rod 6032, ensuring that the movement trajectory of the suspension rope 602 is stable and controlled, and preventing the suspension rope 602 from swaying laterally or oscillating excessively due to the non-uniform force on the suspension component 2 or complex external wave disturbances.

[0039] For example, the suspension assembly 6 can work together with the reset energy-absorbing assembly 4 to share the load during wave impact, further improving the overall impact resistance and service life of the energy-absorbing device, and effectively suppressing the sway of the suspension component 2, thereby enhancing the overall safety and stability of the device under extreme sea conditions.

[0040] In some implementations, reference Figure 1 , Figure 6 and Figure 7 As shown, in order to prevent the free swaying of the suspension block 601 from causing structural interference or fatigue damage, the suspension assembly 6 includes a connecting plate 605, a limiting spring 606, a limiting base 607, and a snap-fit ​​block 608. The end of the suspension block 601 facing away from the suspension rope 602 is fixedly connected to the connecting plate 605. The snap-fit ​​block 608 is provided with a slot 6081 for receiving the connecting plate 605 and is connected to the limiting base 607 on the upper surface of the base plate 101 through the limiting spring 606. The connecting plate 605 and the snap-fit ​​block 608 can be detachably connected by bolts.

[0041] Specifically, under the elastic action of the limiting spring 606, the suspension block 601 is always in a controlled and constrained state, effectively limiting the free swaying of the suspension block 601. When the force of the waves is large, the suspension rope 602 is tightened and drives the suspension block 601 to move upward. At this time, the connecting plate 605 drives the locking block 608 to move relative to the limiting base 607, and the limiting spring 606 is gradually stretched.

[0042] In some implementations, reference Figures 1 to 3 As shown, the suspension component 2 has a hollow cavity and includes a hinge section 201 and a suspension section 202. One end of the hinge section 201 is hinged to the column 102, and the other end is fixed to the suspension section 202. The end of the suspension section 202 facing away from the hinge section 201 is provided with a mounting component 7 for mounting the stop component 3. Specifically, the suspension component 2 presents a combination of "hinge + suspension". The hinge section 201 is hinged to the column 102, allowing the suspension component 2 to swing around the column 102 when impacted by waves, thereby effectively releasing some of the impact energy. The suspension section 202, through its rigid connection with the hinge section 201 and its own hollow cavity structure, gives the suspension component 2 good buoyancy and weight reduction, reducing the support burden, lowering frictional resistance, and improving the response flexibility of the suspension component 2 on the water surface.

[0043] In some implementations, reference Figure 1 , Figure 2 and Figure 5 As shown, the mounting component 7 has an interlocking groove 701 and an interlocking through groove 702. The abutment component 3 includes a fixedly connected plug section 301 and a guide section 302. The plug section 301 is provided with a plug screw 303. The plug groove 701 is used for the plug section 301 to be inserted. When the plug section 301 is inserted into the plug groove 701, part of the plug screw 303 is located in the interlocking through groove 702. That is, the abutment component 3 can quickly connect with the mounting component 7 in a plug-in engagement manner. At the same time, the interlocking through groove 702 accurately limits and aligns the plug screw 303, improving the positioning accuracy and structural stability during the assembly process.

[0044] Meanwhile, the guide section 302 has a receiving port 3021. With the help of the receiving port 3021 of the guide section 302, the impact load of the wave fluid can be effectively concentrated and guided, so that the device as a whole can more fully absorb the impact force of the wave, reduce the impact of the wave on the base 1, and extend its service life.

[0045] In some implementations, reference Figure 1 and Figure 5 As shown, the guide section 302 has an arc-shaped outline, and the guide section 302 extends above the sea level. This allows it to more effectively block fluids during wave impact. At the same time, the arc-shaped structure is more flexible under stress, which can effectively disperse concentrated loads, reduce structural fatigue, and improve the overall impact resistance and service life of the machine.

[0046] In some implementations, reference Figure 2 and Figure 5 As shown, in order to further improve the connection stability between the mounting part 7 and the blocking part 3, a fixing plate 8 is fixedly connected to the upper end of the plug section 301. The upper surface of the suspension section 202 is provided with a fixing screw 2021, and the fixing plate 8 is provided with a through hole 801 for the fixing screw 2021 to pass through. When the blocking part 3 is installed on the mounting part 7, the fixing screw 2021 passes through the through hole 801, and then the fixing plate 8 and the suspension section 202 are fastened together by a nut, thereby realizing a double stable connection of the blocking part 3.

[0047] In some implementations, reference Figures 1 to 3 As shown, the suspended section 202 has connecting ear plates 9 on both sides of its width-directed opposite side walls. Specifically, Figure 1 The base 1 shown is only a partial illustration. In reality, each base 1 has multiple energy-absorbing mechanisms regularly arranged along its length, and each energy-absorbing mechanism is equipped with a corresponding suspension component 2. To further improve the connection stability between adjacent suspension components 2 and the overall structural load-bearing capacity, two adjacent connecting lugs 9 can be connected by connecting ropes. After connection, the multiple suspension components 2 can form an integrated coordinated motion unit under the impact of waves, effectively dispersing and transmitting wave impact loads, thereby significantly enhancing the structural stability and impact resistance of the overall energy-absorbing device.
