Description

Technical Field

[0001] This invention relates to the field of wave-breaking device technology, and in particular to a wave-breaking device based on the energy dissipation of tension structure compression and lens reflection. Background Technology

[0002] Traditional fixed or floating breakwaters mostly rely on directly reflecting waves or guiding waves uphill, using numerous energy-dissipating structures on the slope to absorb wave energy. These types of breakwaters must withstand extremely high wave impact loads, placing extremely high demands on the material properties and strength of the structure itself. Fixed breakwaters are inherently bulky, requiring construction from the seabed upwards, consuming large amounts of sand and gravel, and resulting in high costs. Floating breakwaters, on the other hand, must directly resist massive wave loads at the water surface, lacking measures to mitigate or disperse wave loads. This places high demands on the strength of the structure itself, the mooring system, and the seabed anchorage or holding anchor, similarly leading to significantly increased costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a wave-breaking device based on tension structure compression energy dissipation and lens reflection, which solves the problems of traditional fixed or floating breakwaters bearing excessive wave loads, requiring extremely high structural strength and material properties, high construction costs, and lacking a device to mitigate and effectively dissipate wave energy.

[0004] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0005] A wave-damping device based on tension structure compression energy dissipation and lens reflection includes multiple lens seabed structures for reflecting waves propagating from the open sea and multiple sets of wave energy dissipation components for dissipating wave energy from the open sea. The multiple lens seabed structures and the multiple sets of wave energy dissipation components are evenly distributed at intervals along the circumference of the target sheltered sea area, and the lens seabed structures are located between two adjacent sets of wave energy dissipation components. The lens seabed structure is a spoon-shaped structure with a central protrusion and a gentle slope towards the seabed around the edges. Each set of wave energy dissipation components includes several wave energy dissipation components arranged in an array. The wave energy dissipation components are components capable of compression deformation in both vertical and horizontal directions.

[0006] In one embodiment of the present invention, the lens seabed structure is used to reflect incident waves. That is, when a wave is incident parallel to the vertical projection of the sea area above the lens seabed structure from one side, the wave will be refracted and deflected, thereby deflecting and propagating to the incident direction.

[0007] In one embodiment of the present invention, the water depth distribution of the sea area vertically projected above the lens seabed structure is expressed as follows: ;

[0008] in, The depth of the sea area is the vertical projection above the lens seabed structure, and it is also the height of the upper surface of the lens seabed structure above the sea level. Reference refractive index; The bottom radius of the lens seabed structure; As a variable, and The radius of any part of the upper surface of the lens seabed structure; The depth is the water depth from sea level to seabed; the shape of the upper surface of the lens seabed structure is determined by the water depth distribution expression.

[0009] In one embodiment of the present invention, the wave energy dissipator includes a first shell and a second shell that passes through the first shell and is slidably connected to the first shell. Both the first shell and the second shell are rhomboid in shape and can be compressed and deformed in both the vertical and horizontal directions. The first shell and the second shell are connected by a first telescopic tension damping rod.

[0010] In one embodiment of the present invention, the first housing includes a plurality of first rectifier tips arranged symmetrically in pairs, a plurality of first shell plates movably connected to the first rectifier tips, and a second shell plate connected to the first rectifier tips and disposed on the side of the first housing away from the second housing. A second telescopic tension damping rod perpendicular to each other is installed between two symmetrically arranged first rectifier tips.

[0011] In one embodiment of the present invention, the second housing also includes a plurality of second rectifier tips arranged symmetrically in pairs and passing through the first rectifier tip, a plurality of third housing plates located inside the first housing plate, and a fourth housing plate connected to the second rectifier tips and disposed on the side of the second housing away from the first housing; a third telescopic tension damping rod perpendicular to each other is installed between two symmetrically arranged second rectifier tips, and the second rectifier tips are movably connected to the third housing plate through a connecting plate, and the second housing plate and the fourth housing plate are connected by a first telescopic tension damping rod.

[0012] In one embodiment of the present invention, a plurality of first water-stop strips are provided between the first rectifier tip and the second rectifier tip, and a plurality of second water-stop strips are provided between the plurality of first shell plates and the third shell plate.

[0013] In one embodiment of the present invention, the second shell plate and the fourth shell plate each include an outer shell plate that is disposed corresponding to and connected to the rectifying angle, a middle shell plate that is installed between two adjacent outer shell plates, and an inner shell plate that is connected to the outer shell plate and the middle shell plate respectively. The middle shell plate is also connected to the first shell plate or the third shell plate, and the inner shell plate is also connected to the first telescopic tension damping rod.

[0014] In one embodiment of the present invention, both the outer shell plate and the inner shell plate are provided with water-stopping sheets, and the middle shell plate is provided with a plurality of third water-stopping strips on the upper and lower surfaces along its outer edge.

[0015] As described above, the wave-damping device based on tension structure compression energy dissipation and lens reflection of the present invention has the following beneficial effects: 1. The upper shell of the core component that plays the role of wave reflection in the lens seabed structure of the present invention has no special requirements for the lower structure, so the structure is simple and easy to build and install; and the lens seabed structure is arranged on the seabed and does not protrude from the water surface. Compared with the floating structure on the water surface, the wind, wave and current load it is subjected to is greatly reduced. Therefore, its structural strength requirements are also low, the material strength requirements are also low, the strength requirements for installation and fixing are also low, the stability is high, and the ability to resist severe sea conditions is strong, which greatly reduces the construction cost, installation cost and material cost;

[0016] 2. The diamond-shaped wave energy dissipating body in this invention adopts the principle of energy dissipation through compression deformation, which avoids the working mode of direct wave reflection commonly used by traditional rigid breakwaters when resisting sea waves. This significantly reduces the impact load of waves on the structure itself and can still ensure its safety when facing extremely large waves. In addition, the diamond-shaped wave energy dissipating body has high wave energy dissipation efficiency, and the combined action of multiple rows of diamond-shaped wave energy dissipating bodies also greatly increases the overall level of wave energy dissipation, which can significantly reduce wave energy.

[0017] 3. The diamond-shaped wave energy dissipating body in this invention can be a tension leg mooring system based on gravity anchorage. The mooring system is simple to install and deploy, does not require deep-sea seabed operations, and effectively reduces the construction and installation costs of the mooring system.

[0035] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0036] Please see Figures 1 to 15 This invention provides a wave-damping device based on tension structure compression energy dissipation and lens reflection. It includes multiple lens-shaped seabed structures 1 for reflecting waves propagating from the open sea and multiple sets of wave energy dissipation components 2 for dissipating wave energy. The multiple lens-shaped seabed structures 1 and the multiple sets of wave energy dissipation components 2 are evenly distributed along the circumference of the target sheltered sea area, with the lens-shaped seabed structures 1 located between adjacent sets of wave energy dissipation components 2. It should be noted that in this embodiment, the lens-shaped seabed structure 1 is an Eaton lens-shaped seabed structure, and the wave energy dissipation components 21 of the wave energy dissipation components 2 are rhomboid wave energy dissipation components. Both the Eaton lens-shaped seabed structure 1 and the rhomboid wave energy dissipation components 21 are arranged around the sea area to be sheltered, reflecting and dissipating wave energy from the open sea, significantly reducing or even eliminating the impact of severe open sea waves on the floating or fixed structures arranged in the sheltered sea area, thus playing a wave-damping role. Figure 1 As shown.

[0037] Lens seabed structure 1 is a spoon-shaped structure with a central bulge and a gentle slope towards the seabed. In other words, Eaton lens seabed structure 1 is a spoon-shaped device with a central bulge and a gentle slope towards the seabed. Figure 2 As shown; the lens-shaped seabed structure 1 serves to reflect incident waves. Specifically, when a wave is incident on a region of the sea parallel to the vertical projection above the lens-shaped seabed structure 1, the wave is refracted and deflected. Within this region, the wave gradually rotates 180 degrees before propagating to the incident direction. It should be noted that the wave ray distribution is as follows... Figure 3 As shown, it is important to note that the normal direction of the crest line is the direction of wave propagation. The curve tangent to the direction of wave propagation is called the wave ray, also known as the ray, which is the path of wave propagation.

[0038] The expression for the water depth distribution of the sea area projected vertically above the lens seabed structure 1 is as follows: In the formula The depth of the sea area is the vertical projection above the lens seabed structure 1, and it is also the height of the upper surface of the lens seabed structure 1 above the sea level. Reference refractive index; Let be the bottom radius of the lens-shaped seabed structure 1; As a variable, and Let be the radius of any part of the upper surface of the lens seabed structure 1; The water depth is from sea level to seabed. The shape of the upper surface of the lens seabed structure 1 is determined by the water depth distribution expression. The lens seabed structure 1 can adopt materials and structural forms such as hollow thin-shell steel plate structure or solid concrete structure. The key is that the shape of the upper surface should be designed according to the focal position of the specified parallel incident waves.

[0039] Each wave energy dissipation component 2 includes several wave energy dissipation bodies 21 arranged in an array. Each wave energy dissipation body 21 is a component capable of compressive deformation in both vertical and horizontal directions. It should be noted that the rhomboid wave energy dissipation body 21 is a device capable of compressive deformation in both vertical and horizontal directions, as shown in the bird's-eye view below. Figure 4 As shown; this device can be moored on the sea surface using a tension leg mooring system, which can be fixed to the seabed using a gravity anchor, such as... Figure 5 As shown; the wave energy dissipator 21 includes a first shell 211 and a second shell 212 that passes through the first shell 211 and is slidably connected to the first shell 211. The first shell 211 and the second shell 212 are both rhomboid in shape and can be compressed and deformed in both vertical and horizontal directions. The first shell 211 and the second shell 212 are connected by a first telescopic tension damping rod 4.

[0040] Please see Figures 6 to 8The first housing 211 includes a plurality of first rectifying horns 2111 arranged symmetrically in pairs, a plurality of first housing plates 2112 movably connected to the first rectifying horns 2111, and a second housing plate 2113 connected to the first rectifying horns 2111 and disposed on the side of the first housing 2111 away from the second housing 212. A second telescopic tension damping rod 5 perpendicular to each other is installed between two symmetrically arranged first rectifying horns 2111. The second housing 212 includes a plurality of second rectifying horns 2111 arranged symmetrically in pairs and passing through the first rectifying horns 2111. The second rectifying angle 2121, multiple third shell plates 2122 located inside the first shell plate 2112, and a fourth shell plate 2123 connected to the second rectifying angle 2121 and located on the side of the second shell 212 away from the first shell 211, are connected to the second rectifying angle 2121. A third telescopic tension damping rod 6 perpendicular to each other is installed between the two symmetrically arranged second rectifying angles 2121. The second rectifying angle 2121 is movably connected to the third shell plate 2122 through a connecting plate 7. The second shell plate 2113 and the fourth shell plate 2123 are connected through a first telescopic tension damping rod 4.

[0041] It should be noted that the first rectifying tip 2111 is directly connected to the surrounding first shell plate 2112 via hinge 8, and the second rectifying tip 2121 is connected to several connecting plates 7, which are connected to the surrounding third shell plate 2122 via hinge 8; the rectifying tip is rigidly connected to the second telescopic tension damping rod 5 or the third telescopic tension damping rod 6; the presence of hinge 8 allows the rhomboid wave energy dissipator 21 to deform horizontally about two mutually perpendicular axes of symmetry, with one axis shortening and the other axis lengthening; the telescopic tension damping rod in this embodiment is a retractable or retractable round rod, which is a structure formed by multiple nested cylindrical rods, internally containing The system includes springs connecting both ends of the round rod and dampers that prevent the round rod from elongating or shortening, forming a spring-damped rod system. When installing the second telescopic tension damping rod 5 or the third telescopic tension damping rod 6, the length of the spring inside the telescopic tension damping rod is adjusted so that the spring is in a state of pre-tension with a tendency to contract, and a tension force is applied to both ends of the rod towards the center of the rod. Since the rhomboid wave energy dissipator 21 has the second telescopic tension damping rod 5 and the third telescopic tension damping rod 6 installed perpendicularly to each other in the horizontal direction, it is subjected to the tension force at the center of the rod on two mutually perpendicular axes of symmetry. Therefore, it is in a dynamic equilibrium under the two mutually perpendicular pre-tension forces, which is to say, it becomes a tension structure.

[0042] When the rhomboid wave energy dissipator 21 deforms under external force, if the horizontal axis undergoes compressive deformation, the preload applied to both ends by the telescopic tension damping rod of the horizontal axis will decrease. Under the constraint of the geometric structure, the longitudinal axis of the rhomboid wave energy dissipator will be forced to elongate, and the telescopic tension damping rod of the vertical axis will also be forced to elongate. At the same time, the internal spring is stretched, resulting in an increase in the tension applied to both ends of the rod. In addition, the damper inside the rod will also hinder the elongation or compressive deformation of the rod, causing the rhomboid wave energy dissipator to resist its compressive deformation and try to restore its original shape. Finally, the rhomboid wave energy dissipator will gradually restore its original shape after compressive deformation and return to the dynamic equilibrium of the tension structure. Figure 9 As shown;

[0043] It should also be noted that, in the vertical direction, four telescopic tension damping rods connect the top and bottom shell plates, namely the first telescopic tension damping rod 4, as shown below. Figure 10 As shown; the difference between the four vertical telescopic tension damping rods (first telescopic tension damping rod 4) and the horizontal telescopic tension damping rods (second telescopic tension damping rod 5 and third telescopic tension damping rod 6) of the rhomboid wave energy dissipator 21 is that the internal springs do not have preload, that is, in the initial state, no tension is applied to the outer shell at both ends of the rods towards the center of the rods; when the rhomboid wave energy dissipator 21 is subjected to external wave load and undergoes vertical compression deformation, the distance between the first shell 211 and the second shell 212 will be compressed, and at the same time, the four vertical telescopic tension damping rods will also be compressed. The springs inside the rods generate a rebound force after being compressed, and the dampers inside the rods will also generate a damping force that resists the compression of the rods, so that the rods generate resistance to the compression deformation of the rhomboid wave energy dissipator 21 against the outer shell. After being compressed to the minimum state, the spring tension will cause the rhomboid wave energy dissipator to return to the initial state;

[0044] When the rhomboid wave energy dissipator 21 is subjected to external wave load and undergoes lateral or vertical compression deformation, the air inside it will be compressed, resulting in an increase in gas pressure. At the same time, the work done by the external load will convert the wave energy into the deformation mechanical energy of the rhomboid wave energy dissipator, and finally into the heat energy of the internal air and the damper of the telescopic tensioning damping rod, thus achieving the effect of wave energy dissipation.

[0045] Please see Figure 10A plurality of first water-stop strips 9 are provided between the first rectifying tip 2111 and the second rectifying tip 2121, and a plurality of second water-stop strips 10 are provided between the plurality of first shell plates 2112 and the third shell plate 2122. It should be noted that the rectifying tip in this embodiment is hollow, so the installed second rectifying tip 2121 is nested inside the first rectifying tip 2111. Two first water-stop strips 9 are provided between the upper and lower rectifying tips to prevent water from entering the interior of the rectifying tip. The size of the second rectifying tip 2121 is slightly smaller than that of the first rectifying tip 2111, and a small panel (connecting plate 7) extends out from its side. The lower hinge 8 is used to connect to the third shell plate 2122. When the rhomboid wave energy dissipator 21 is vertically compressed and deformed, the rectifier tip will also be vertically compressed and deformed along with the first shell plate 2112 or the third shell plate 2122. At the same time, two second water-stop strips 10 are set between the first shell plate 2112 and the third shell plate 2122, respectively fixed to the edge of the shell plates of the first shell 211 and the second shell 212, forming a waterproof layer around the horizontal direction of the shell, which can prevent external water from entering the interior of the rhomboid wave energy dissipator. The first water-stop strip 9 and the second water-stop strip 10 can be made of rubber.

[0046] Please see Figures 11 to 14 The second shell plate 2113 and the fourth shell plate 2123 each include an outer shell plate 31 that is set and connected to the rectifier sharp corner, a middle shell plate 32 installed between two adjacent outer shell plates 31, and an inner shell plate 33 that is connected to the outer shell plate 31 and the middle shell plate 32 respectively. The middle shell plate 32 is also connected to the first shell plate 2112 or the third shell plate 2122, and the inner shell plate 33 is also connected to the first telescopic tension damping rod 4. The surfaces of the outer shell plate 31 and the inner shell plate 33 are provided with water-stop plates, and the middle shell plate 32 is provided with several third water-stop strips on the upper and lower surfaces along its outer edge.

[0047] It should be noted that the outer shell plate 31 is fixedly connected to the rectifier sharp corner, the middle shell plate 32 is fixedly connected to the first shell plate 2112 or the third shell plate 2122, and the inner shell plate 33 is fixedly connected to the four vertical first telescopic tension damping rods 4; both the outer and inner shell plates are provided with a whole piece of water-stop rubber sheet, while the middle shell plate 32 has two third water-stop strips respectively set on the upper and lower surfaces along its outer edge. Thus, the three shell plates partially overlap each other, together forming a waterproof shell covering the top surface; diamond wave The second shell plate 2113 and the fourth shell plate 2123 of the wave energy dissipator 21 have the same structure. When the rhomboid wave energy dissipator 21 undergoes horizontal compression deformation, its top and bottom shell plates, namely the second shell plate 2113 and the fourth shell plate 2123, move along with their subordinate structures. However, due to the limitation of the horizontal and vertical axis tension damping rods, their deformation will not be too large, so that the top and bottom shell plates are always in a waterproof state during the deformation process, and water will not enter the interior of the rhomboid wave energy dissipator 21.

[0048] To elaborate further, the working principle of the rhomboid wave energy dissipator 21 is as follows: When the rhomboid wave energy dissipators 21 are arranged laterally at a certain interval and staggered longitudinally to form an array, their working principle is as follows: Figure 15 As shown; when ocean waves propagate from the front of the array of diamond wave energy dissipators 21, after the waves are diverted by the sharp corners of the diamond wave energy dissipators 21, they are obliquely reflected by the sidewalls. After the adjacent diamond wave energy dissipators 21 reflect the waves obliquely in opposite directions, the two waves will converge together. The waves converge and the wave height increases sharply, exceeding the wave steepness limit, thus causing wave breaking. At the same time, a large amount of turbulence is generated, forming a wave breaking jet mixed with a large amount of air. In this process, the wave energy is dissipated by a large number of tiny eddies. Meanwhile, when the sidewalls of the diamond wave energy dissipators 21 are impacted by wave loads, they will undergo lateral compression deformation. When the wave height increases sharply, the waves will compress and strike the diamond wave energy dissipators 21 from above, and vertical compression deformation will also occur. Both of these deformations convert the wave energy into internal air and damper heat energy and dissipate it.

[0049] The remaining waves and breaking wave jets after passing through the first row of diamond-shaped wave energy dissipators 21 continue to propagate downwards to the second row of diamond-shaped wave energy dissipators 21, producing the same wave energy dissipation effect as the first row, and further dissipating wave energy, thereby protecting marine structures in the rear sea area from the attack of severe waves.

[0050] To elaborate further, the overall layout and working principle of this invention are as follows: Figure 1 As shown, Eaton lens seabed structures 1 and diamond-shaped wave energy dissipators 21 can be arranged in a ring around the protected sea area or partially arranged in the direction of the main waves. The Eaton lens seabed structures 1 and diamond-shaped wave energy dissipators 21 are arranged at intervals. Some of the incident waves are reflected back by the Eaton lens seabed structures 1, while the remaining part needs to be dissipated by the diamond-shaped wave energy dissipators 21. This leaves the necessary space for ship navigation, facilitating ships to enter the protected sea area for operations.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
