Description

Technical Field

[0001] This invention belongs to the field of floating breakwater technology and is used in river, lake and coastal protection projects. In particular, it relates to a design method and periodic unit structure for a floating structure of ship wave energy dissipation and wave-damping arc plate. Background Technology

[0002] Ship waves are waves generated on the water surface by ships moving across it, displacing water on either side and causing changes in flow velocity and pressure. Ship waves mainly accumulate on the water surface, propagate directionally, typically along the direction of the ship's movement, and gradually attenuate during propagation. Ship waves have a direct impact and erosion effect on coastlines and river channels. In waterways densely covered with mangroves, ship waves have a significant impact on mangroves. Mangroves have multiple ecological functions, purifying waters, maintaining biodiversity, providing habitats for numerous fish, shrimp, crabs, and shellfish, and serving as important habitats and migratory stopover points for waterbirds and migratory birds. Constructing breakwaters is the most effective and direct method to reduce the impact of ship waves on mangroves.

[0003] Floating breakwaters are increasingly valued in the field because they can adapt to various conditions, including deep waters, soft foundations, large tidal ranges, and the introduction of new water for exchange. They are not limited by foundation conditions and can be used in diverse aquatic environments with minimal impact on sediments and the ecosystem, making them more environmentally friendly. Furthermore, their floating structure provides excellent mobility, allowing for rapid deployment as temporary structures when needed. In particular, floating breakwaters are ideal for protection in river channels densely covered with mangroves, where the primary impact is from ship waves and wave energy is concentrated at the water surface.

[0004] Existing research indicates that floating breakwaters are effective at dissipating short-period waves, but studies on their effectiveness against ship waves are scarce. Therefore, researching and developing floating breakwaters that provide excellent protection under ship wave conditions is crucial. Current research is still in its early stages regarding structural forms, wave-dissipating mechanisms, design, and engineering applications. Thus, developing a universally applicable energy-dissipating and wave-damping floating breakwater structure with an arc plate, suitable for different aquatic environments, and elucidating its wave-dissipating mechanism under ship waves, are urgent problems that need to be solved.

The floating guide pile fixing module includes a foundation block and telescopic guide piles. The foundation block is used to fix the device to the bottom of the ecological waterway. One end of the telescopic guide pile is located on the side of a cross-shaped support on the foundation block, and the other end is connected to a telescopic guide pile buoy. The telescopic guide pile buoy floats on the water surface, and the telescopic guide pile can extend and retract with changes in water level. The plant floating wave-damping module includes a wave-damping float, a nutrient solution inlet, and an aquatic plant fixing plate. The wave-damping float floats on the water surface while simultaneously damming waves. The nutrient solution inlet is located within the wave-damping float, and the aquatic plant fixing plate is located on top of the nutrient solution inlet for fixing the ecological plants. The powered floating wave-damping module includes a wave-damping float, a nutrient solution delivery component, and a power assembly. The device has many structural components and includes a floating plant module, making operation and maintenance complex and its practicality limited.

A rectangular wave-dissipating inner frame 220 is located within the rectangular wave-dissipating outer frame 210, and its front and rear outer surfaces slide against the front and rear inner surfaces of the rectangular wave-dissipating outer frame 210. Two front and rear inner frame sliding grooves 221a and 221b are spaced apart along the length of the front and rear frame bars of the rectangular wave-dissipating inner frame 220. Each front and rear sliding connecting rod 230a, 230b has one end fixedly connected to the front and rear inner surfaces of the rectangular wave-damping outer frame 210, and the other end correspondingly passes through the front and rear inner frame sliding grooves 221a, 221b and is fixedly connected to the front and rear connecting blocks 113a, 113b. Of course, the number of front and rear sliding connecting rods 230a, 230b is not limited to the number in this embodiment and should be set according to design requirements.

[0038] Example 1:

[0039] This embodiment describes a design method for a floating structure with wave-dissipating and wave-damping arc plates, such as... Figures 1 to 6As shown, a periodic unit structure 1 with a triple wave-dissipating and energy-dissipating module is constructed. Multiple periodic unit structures 1 are connected to form an arc-plate floating structure, including: First, multiple arc-shaped perforated plates 3 are set on the outer side of the periodic unit structure 1. When waves travel to the arc-shaped perforated plates 3, they interact and break up; Second, using wave modulation theory, the arc-shaped perforated plates 3 are connected and combined in sequence to form a rhythmic structure, so that the waves have a phase difference during propagation and the wave propagation path is changed by wave-wave interference; Third, a cuboid wave-dissipating cavity 2 composed of perforated plates is constructed inside the periodic unit structure 1, so that the waves move back and forth in it, further dissipating the energy of the waves.

[0040] The method includes the following steps:

[0041] Step 1: Collect hydrological conditions and ship navigation characteristics data of the proposed shelter area, including the design navigable water level h and ship speed. Ship wave height H, wavelength L, and ship wave direction .

[0042] Step 2: Determine the dimensional parameters and layout of the arc plate floating structure. The arc plate floating structure is formed by connecting multiple periodic unit structures 1. The vertical height m of the arc plate floating structure is 2-4 times the wave height H of the ship's sailing waves.

[0043] Step 3: Determine the periodic unit structure 1 and its layout. Each periodic unit structure 1 has multiple identical arc-shaped perforated plates 3 on its outer side and a cuboid wave-damping cavity 2 containing n layers of wave-damping perforated baffles 23 on its inner side, where n ≥ 1. Multiple identical arc-shaped perforated plates 3 are evenly arranged on the outer side of the cuboid wave-damping cavity 2. The outer side includes at least the bottom, top, and front facing the waves. The arc-shaped perforated plates 3 on each side are closely connected to form N arched protrusions. The bottom surfaces are on a horizontal line, and the top forms an orderly undulating wave-like surface, where N ≥ 3. In this preferred embodiment, the outer side includes the front, bottom, and top, and the number of arc-shaped perforated plates 3 on each side is N = 4.

[0044] The length r of the line connecting the endpoints A and C of the arc-shaped perforated plate 3 disposed on the cuboid wave-damping cavity 2 is related to the direction of the ship's waves. The dominant wavelength L satisfies the following formula:

[0045]

[0046] In the formula, , This indicates the diffraction secondary order, and is taken as a positive number.

[0047] The straight line AB or BC formed by the vertex B to the endpoint A or C of the arc-shaped perforated plate 3 cross section is perpendicular to the direction of the ship's wave. vertical.

[0048] Preferably, in this embodiment, the cuboid wave-damping cavity 2 has rectangular perforated plates 22 on its top, bottom, front, and back sides, and square perforated plates 21 on its left and right sides. Multiple periodic unit structures 1 are sequentially and tightly connected via the square perforated plates 21 to form the arc-plate floating structure. The length 'a' of the periodic unit structure 1 is related to the number of arc-shaped perforated plates 3. Must meet: .

[0049] Example 2:

[0050] This embodiment is a floating periodic unit structure for ship wave energy dissipation and wave-damping arc plates. Based on the above-described arc plate floating structure design method, each periodic unit structure has multiple identical arc-shaped perforated plates 3 on its outer side and a cuboid wave-damping cavity 2 containing n layers of wave-damping perforated baffles on its inner side, where n≥1. Multiple identical arc-shaped perforated plates 3 are evenly arranged on the outer surface of the cuboid wave-damping cavity 2. The outer surface includes at least the front, bottom, and top. The arc-shaped perforated plates 3 on each surface are closely connected to form N arched protrusions, where N≥3. The length r of the line connecting the endpoints A and C of the arc-shaped perforated plates 3 on the cuboid wave-damping cavity 2 is related to the direction of the ship wave. The dominant wavelength L satisfies the following formula:

[0051]

[0052] In the formula, , The diffraction secondary order is represented by a positive integer, and the length 'a' of the arc-shaped floating unit structure and the number of arc-shaped perforated plates 3 are also considered. Must meet: .

[0053] Preferably, in this embodiment, the cuboid wave-damping cavity 2 has rectangular perforated plates on its top, bottom, front, and back sides, and square perforated plates 21 on its left and right sides. Two layers of wave-damping perforated partition plates 23 are equally spaced inside the cuboid wave-damping cavity 2.

[0054] Example 3:

[0055] Based on the above embodiments, this embodiment is an improvement regarding the placement of the arc-shaped perforated plate 3. In this embodiment, the arc-shaped perforated plate 3 is provided on the upper, lower, front, and rear four outer surfaces of the cuboid wave-damping cavity 2. The layout, structure, and size of the arc-shaped perforated plates 3 on the four outer surfaces are identical. Providing the arc-shaped perforated plate 3 on all four sides has a better wave-damping and energy-dissipating effect, such as... Figure 3-4 As shown.

[0056] Example 4:

[0057] This embodiment is a specific example that collects hydrological conditions and ship navigation characteristics data of the sea area to be protected:

[0058] The hydrological conditions of the proposed sheltered sea area include: a design navigable water level of 3.6m, a ship wave height H of 0.353m, a wavelength L of 7.54m, and a ship wave direction... It is 35.14°.

[0059] Step 2: Determine the structural dimensions and layout of the periodic unit structure of the arc-plate floating structure:

[0060] The arc-shaped floating structure is formed by connecting multiple periodic unit structures 1. Each periodic unit structure 1 consists of two parts: multiple identical arc-shaped perforated plates 3 and a cuboid wave-damping cavity 2. The cuboid wave-damping cavity 2 has rectangular perforated plates 22 on its top, bottom, front, and back sides, and square perforated plates 21 on its left and right sides. Two layers of wave-damping perforated baffles 23 are provided. The two layers of perforated baffles 23 can be placed vertically or horizontally. In this embodiment, they are placed vertically at equal intervals. Figure 1-4 As shown.

[0061] Preferably, in this embodiment, the number of arc-shaped perforated plates 3 in the periodic unit structure 1 is 12, with the same structure, shape, and size. They are respectively arranged on the upper, lower, and front three faces of the cuboid wave-damping cavity 2, with 4 (N=4) arc-shaped perforated plates 3 arranged on each face. They are connected closely in sequence along the cuboid wave-damping cavity 2. The chord AC of all the arc-shaped perforated plates 3 is on the same straight line and connected to the cuboid wave-damping cavity 2. The arc-shaped perforated plates 3 below the cuboid wave-damping cavity 2 are symmetrically arranged with the arc-shaped perforated plates 3 above. The straight line AB or BC formed by the center point (vertex) B of the arc-shaped cross-section of the arc-shaped perforated plate 3 to the endpoint A or C is parallel to the direction of the ship's waves. Vertical, such as Figures 1 to 5 As shown.

[0062] Since the energy of ship waves mainly concentrates on the water surface, the ratio of the vertical height m of the periodic unit structure 1 to the ship wave height H is calculated as 4 times in this embodiment: m = 4H = 4 * 0.353 = 1.41m. Based on the hydrological conditions and ship movement characteristics of the proposed shelter area, and the relationship between the straight line BD in the arc-shaped perforated plate 3 and the height b of the cuboid wave-damping cavity 2, a floating energy-dissipating and wave-damping arc plate structure suitable for the proposed shelter area is finally designed.

[0063] The ship's characteristic data described in this embodiment shows a ship wave wavelength L = 7.54m and a ship wave direction... For ease of calculation, we take 35° here, and substitute it into the following formula:

[0064]

[0065] Because the navigable water level in this embodiment is relatively shallow, h=3.6m, It should not be too long, so Taking 10, we can calculate that r is 0.46m (rounded to two decimal places).

[0066] According to the design scheme, the ship's wave is perpendicular to the line connecting the vertex B and the endpoint A of the arc-shaped perforated plate 3, that is:

[0067] ∠BAD = 180° - 90° - 35° = 55°

[0068] According to the trigonometric function tan =BD / AD, the straight line BD is calculated to be 0.33m, and the height b of the cuboid wave-damping cavity 2 is b = m - BD*2 = 1.41 - 0.33*2 = 0.75m.

[0069] The length of the cuboid wave-damping cavity 2 is a = Nr = 4 × 0.46 = 1.84 m, that is, the length of each periodic unit structure 1 is 1.84 m.

[0070] The summarized data for the periodic unit structure described in this embodiment are as follows: vertical height m = 1.41m, number of arc-shaped perforated plates 3N = 3 × 4 = 12, ship wave wavelength L = 7.54m, and ship wave direction... The angle is 35.14°; the length of the periodic unit structure 1 is a = 1.84m, the height of the cuboid wave-damping cavity 2 is b = 0.75m, the height of the arc-shaped perforated plate 3 is BD = 0.33m, and the width is r = 0.46m.

[0071] This embodiment uses a ship model scaled down to the size of a 5000DWT bulk carrier at a ratio of 1:10. The model dimensions are 7m × 1.5m. The experiment was conducted at a ship speed of 1.35m / s and a water depth of 1.13m to study the wave-dissipating characteristics of the wave-damping structure. The experiment showed that the effective energy dissipation rate of the wave-damping structure is 60%-75%.

[0072] Figure 6 This is a diagram illustrating the wave-dissipating effect of the energy-absorbing and wave-damping arc-plate floating structure obtained by the design method described in this invention. In the diagram, the black portion represents the arc-plate floating structure of this invention. The line in front of it (left side) represents the change in the ship's wave height, and the line behind it (right side) represents the ship's wave state after passing through the arc-plate floating structure. The diagram shows the change in the wave's free surface height. The height difference of the free surface behind (right side) the energy-absorbing and wave-damping arc-plate floating structure is significantly reduced, and the wave becomes more stable, indicating a significant reduction in wave energy. This achieves the effect of shielding the area behind the structure and effectively protects the mangrove vegetation zone.

[0073] This invention constructs a periodic unit structure 1 with a triple wave-dissipating and energy-dissipating module. Multiple periodic unit structures 1 are connected to form a novel arc-plate floating structure with a rhythmic structure. This causes a phase difference in wave propagation, and utilizes wave-wave interference to change the wave propagation path, achieving an effective energy dissipation rate of 60%-75%. Simultaneously, it uses high-strength, lightweight, and corrosion-resistant materials, and the structural layout can be flexibly assembled and quickly adjusted according to the actual water area, offering convenient construction and scalability to adapt to changing water environments and needs. The perforated plate design reduces material usage and lowers costs.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to preferred arrangements, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention (such as the order of steps, the deformation of the periodic unit structure, etc.) without departing from the spirit and scope of the technical solutions of the present invention.
