Description

Wave dissipation assembly, wave dissipation dam structure unit, structure, dam, system and construction method

[0001] This application claims priority to Chinese Invention Patent Application (Application No. 202410727497.0) filed on May 30, 2024. TECHNICAL FIELD

[0002] The present patent relates to the technical field of wave dissipation dam, in particular to a wave dissipation assembly, a wave dissipation dam structure unit, a structure, a dam, a system and a construction method. BACKGROUND

[0003] At present, offshore aquaculture generally includes offshore aquaculture and offshore aquaculture (generally water depth 20-80m range). Among them, offshore aquaculture is mainly divided into three categories: aquaculture work ship, aquaculture platform and net cage:

[0004] The net cage is limited by wind and wave, and is still in the stage of being solved. At present, there are some special anti-wind and wave net cages, which have very high manufacturing cost and installation cost, and cannot achieve the effect of fundamentally resisting wind and wave, and the net cage will still be damaged by strong wind and wave. Therefore, the net cage for offshore aquaculture is relatively small.

[0005] The cost of aquaculture work ship is high, and the maintenance cost is also high.

[0006] The aquaculture platform is limited by water depth and cannot be mass-produced, and the steel structure is used for long-term use, which has corrosion problems, and the maintenance cost is also high. In addition, the anchoring system is expensive.

[0007] Another disclosed scheme is to use a floating breakwater to dissipate waves, for example, the patent name is: floating breakwater and wind energy integrated system for deep sea aquaculture (publication number: CN208023503U), which discloses a scheme for dissipating waves by using a floating breakwater. However, the floating breakwater itself has limited wind and wave resistance, and the wave dissipation performance for long-period waves in the open sea is weak (as everyone knows that the ratio of transmitted wave height to incident report, that is, the transmission coefficient, is directly dependent on the ratio of the width of the structure along the wave propagation direction to the incident wavelength), which makes it difficult to achieve good wave dissipation effect (only 30% to 40% of wave dissipation effect). At the same time, the breakwater floats on the sea surface, and it cannot change the flow field in the area where the net cage is located (for example, it cannot change the flow velocity in the area where the net cage is located), so that the use effect of the floating breakwater in the offshore aquaculture field is not good.

[0008] To solve the above problems, the skilled in the art has developed a wave dissipation dam suitable for a water depth of 20-80 m to create a calm sea area suitable for aquaculture, for example, a patent entitled: An Offshore Aquaculture System and Its Design Method (Publication No: CN115581212A) to solve the above problems, which mainly applies a large cylinder foundation and fills the inside to achieve its stability, and has very strong wave resistance. And the patent entitled: An Offshore Wave Dissipation Dam and Offshore Aquaculture System (Publication No: CN117845826A) has a better wave resistance and flow guiding effect by special plane arrangement of the cylinder structure, but the optimization will increase the number of large cylinders, which has certain adverse factors for overall cost control.

[0009] The cost optimization of the above scheme becomes the subsequent optimization direction for the researchers. SUMMARY

[0010] The purpose of the present application is to overcome the problem of how to reduce the cost of a large barrel foundation as a wave dissipation component in the background art, and to provide a through-flow wave dissipation dam construction unit, a through-flow wave dissipation dam, a system and a construction method.

[0011] In order to achieve the above-mentioned purpose of the application, the present application provides the following technical solutions:

[0012] A wave dissipation component, comprising a main flow guide wall and two side flow guide walls connected in a radial manner, the included angle A between the main flow guide wall and one of the side flow guide walls ranges from 90° to 180°, and the included angle B between the main flow guide wall and the other side flow guide wall ranges from 90° to 180°.

[0013] The wave dissipation component described in the present application changes the flow direction near the main flow guide wall by setting the main flow guide wall, and causes water to accumulate outside the main flow guide wall, which is more conducive to the water flow outside the main flow guide wall and the side flow guide wall passing through the wave dissipation component from both sides of the wave dissipation component.

[0014] When the wave hits the wave dissipation component along the main flow guide wall, the wave changes direction twice and changes propagation speed at the main flow guide wall and the junction of the main flow guide wall and the side flow guide wall, respectively, and then the wave continues to propagate forward

away from the main flow guide wall

[0015] When the water flow moves obliquely along the main flow guide wall to the vicinity of the wave dissipating assembly, the main flow guide wall can effectively catch the water flow passing through the wave dissipating assembly from one side of the wave dissipating assembly along the main flow guide wall and the side flow guide wall.

[0016] When the wave obliquely impacts the wave dissipating assembly along the main flow guide wall, the wave is sequentially redirected at the main flow guide wall and at the junction of the main flow guide wall and the side flow guide wall, and then continues to propagate forward at the end of the side flow guide wall

away from the main flow guide wall

[0017] On the basis of the above-mentioned scheme, in the case where the water flow flows along the main flow guide wall and the side flow guide wall to the rear of the wave dissipating assembly, the wave forms wave forces on the two side flow guide walls perpendicular to the side flow guide walls. In the direction perpendicular to the main flow guide wall

defined as the X direction

defined as the Y direction

[0018] Moreover, the relative positions of the main flow guide wall and the two side flow guide walls are arranged in a "Y" shape, which has a much larger bending resistance coefficient in any direction than a single wall structure, has a higher strength-to-weight ratio than the rectangular closed cross section of a traditional caisson structure, and has stronger resistance to instability and deformation than a single pile or plate structure, thereby providing support for the wave dissipating assembly to be used in deep sea harsh conditions with a water depth of 20m-80m.

[0019] At the same time, the relative positions of the main flow guide wall and the two side flow guide walls are arranged in a "Y" shape, so that the overall gravity of the wave dissipating assembly is relatively balanced, and the vertical center of gravity of the wave dissipating assembly can fall within the triangular range formed by the end of the main flow guide wall and the ends of the two side flow guide walls, thereby eliminating the need to set up a large hoisting frame and balance weight on the upper part of the wave dissipating assembly during construction to hoist the wave dissipating assembly. Compared with a wave dissipating structure with a larger eccentricity, the wave dissipating assembly saves hoisting costs and reduces construction costs.

[0020] The wave dissipating assembly has a light structure, and compared with a traditional caisson vertical embankment and a large barrel dam, the wave dissipating assembly mainly comprises several wall bodies, has a higher cost performance, and has a more sustainable development scheme.

[0021] Preferably, the size relationship between the included angle A and the included angle B is A=B±10°.

[0022] Preferably, the two side flow guide wall bodies are symmetrically arranged relative to the main flow guide wall body.

[0023] Preferably, the main flow guide wall body and the two side flow guide wall bodies are circumferentially and uniformly arranged.

[0024] Preferably, the main flow guide wall body and the two side flow guide wall bodies are integrally formed.

[0025] Preferably, the included angle A ranges from 110° to 135°, and / or the included angle B ranges from 110° to 135°.

[0028] Preferably, the wall thickness of the root of the main flow guide wall body is greater than the wall thickness of the outer end, so that the structure of the main flow guide wall body is more optimized according to the stress.

[0029] Preferably, the wall thickness of the root of the side flow guide wall body is greater than the wall thickness of the outer end, so that the structure of the side flow guide wall body is more optimized according to the stress.

[0030] Preferably, the main flow guide wall body and / or the side flow guide wall body is provided with a through hole, so as to reduce the wave force borne by the main flow guide wall body and / or the side flow guide wall body.

[0031] Preferably, the bottom of the main flow guide wall body is provided with a first base, and the first base at least partially protrudes from the side of the main flow guide wall body. The first base is used to expand the cross-sectional area of the bottom of the wave dissipating assembly, so as to optimize the stress borne by the bottom of the main flow guide wall body. If the wave dissipating assembly needs to be installed on the foundation of the bottom, and is not integrally prefabricated with the bottom foundation, the first base can also make it easier to construct the wave dissipating assembly on the foundation of the bottom in the later period, and also reduces the local bearing stress of the foundation of the bottom.

[0032] Preferably, the side flow guide wall body bottom is provided with a first base, which at least partially protrudes from the side of the side flow guide wall body. The first base is used to expand the cross-sectional area of the wave dissipation assembly bottom, so as to optimize the stress on the side flow guide wall body bottom. If the wave dissipation assembly is installed on the bottom foundation, the first base can also make it easier to construct the wave dissipation assembly on the bottom foundation later, and reduce the local bearing stress of the bottom foundation.

[0033] The application also discloses a flow-through wave dissipation dam construction unit, which comprises a first flow-through wave dissipation structure, wherein the first flow-through wave dissipation structure comprises at least one wave dissipation assembly as described in the application, and the first flow-through wave dissipation structure is provided with a first gate for water flow therethrough.

[0034] The flow-through wave dissipation dam construction unit described in the application comprises the wave dissipation assembly described in the application, and the main flow guide wall body is arranged to change the flow direction of water near the main flow guide wall body and make the water on the outside of the main flow guide wall body be dammed up, so that the water on the outside of the main flow guide wall body is more conducive to passing through the first gate along the direction of the main flow guide wall body and the side flow guide wall body.

[0035] When the wave impacts the wave dissipation assembly along the main flow guide wall body, the wave is changed in direction twice at the main flow guide wall body and the junction of the main flow guide wall body and the side flow guide wall body, and then continues to propagate forward at the end of the side flow guide wall body

in the direction away from the main flow guide wall body, at least one side passing through the first gate

[0036] When the water flow moves obliquely along the main flow guide wall body to the vicinity of the wave dissipation assembly, the main flow guide wall body can effectively catch the water flow passing through the wave dissipation assembly from one side of the wave dissipation assembly along the direction of the main flow guide wall body and the side flow guide wall body.

[0037] When the wave impacts the wave dissipation assembly obliquely along the main flow guide wall body, the wave is changed in direction twice at the main flow guide wall body and the junction of the main flow guide wall body and the side flow guide wall body, and then continues to propagate forward at the end of the side flow guide wall body

[0038] Preferably, the primary flow-through wave dissipating structure comprises at least two of the wave dissipating assemblies, and a primary port is formed between adjacent wave dissipating assemblies.

[0039] Preferably, the adjacent wave dissipating assemblies are arranged in the same direction.

[0040] Preferably, the primary port in the primary flow-through wave dissipating structure is formed by side guide walls of adjacent wave dissipating assemblies.

[0041] Preferably, the primary energy dissipation area is surrounded by the main guide wall of the adjacent wave dissipating assembly and the opposite side guide wall of the adjacent wave dissipating assembly, and the width of the primary energy dissipation area narrows from the junction of the main guide wall and the side guide wall to the primary port.

[0042] When the waves or water flow reach the primary flow-through wave dissipating structure, part of the waves or water flow enters the primary energy dissipation area, and another part of the waves or water flow is effectively captured by the main guide wall into the primary energy dissipation area and moves along the main guide wall towards the primary port. In this process, part of the waves will move along the main guide wall and change direction again at the junction of the main guide wall and the side guide wall. The above process will cause the water flow in different areas of the primary energy dissipation area to have different speeds and flow directions, thereby forming water flow rotation under certain working conditions, thereby achieving the purpose of weakening the waves. At the same time, since the width of the primary energy dissipation area from the junction of the main guide wall and the side guide wall to the primary port will continuously narrow, the water level will rise when the water flow in the primary energy dissipation area moves towards the primary port, thereby accelerating the water flow through the primary port in unit time and speed, thereby effectively increasing the flow-through effect of the flow-through wave dissipating dam structure unit.

[0043] Preferably, the adjacent wave dissipating assemblies in the primary flow-through wave dissipating structure are connected.

[0044] Preferably, in the primary flow-through wave dissipating structure, the first breast wall is connected between the adjacent wave dissipating assemblies, and the first breast wall is located at the top of the wave dissipating assembly, and the upper part of the first breast wall protrudes upwards beyond the wave dissipating assembly.

[0045] The first breast wall can only serve as a connecting piece for connecting adjacent wave dissipating assemblies.

[0046] The first breast wall above the high water level is arranged as a wave blocking structure to further reduce waves while not affecting the water flow exchange in daily operation under non-extreme weather conditions, and can also serve as a connection between the two wave dissipating assemblies to enhance the stability of the wave dissipating assemblies on both sides of the primary port.

[0048] Preferably, the primary flow-through wave-dissipation structure further comprises a connecting structure one, and in the primary flow-through wave-dissipation structure, the connecting structure one is connected between adjacent wave-dissipation assemblies, and the connecting structure one is located at the bottom of the primary entrance.

[0049] The connecting structure one can play a connecting role between the wave-dissipation assemblies on both sides of the primary entrance, thereby enhancing the stability of the wave-dissipation assemblies on both sides of the primary entrance, and when it is necessary to fill structures such as rubble at the lower part of the primary flow-through wave-dissipation structure, the connecting structure one can also play a surrounding role.

[0050] Preferably, the projection of the main flow guide wall in the direction of the side flow guide wall on the same side of the adjacent wave-dissipation assembly of the same level covers the root of the side flow guide wall. In this way, the problem of air trapping caused by the vertically impinging of obliquely incident waves on the side flow guide wall can be effectively reduced or eliminated, thereby reducing the stress of waves on the side flow guide wall.

[0051] Preferably, the primary flow-through wave-dissipation structure is provided with a secondary flow-through wave-dissipation structure on one side close to the side flow guide wall, wherein a secondary entrance is provided through the secondary flow-through wave-dissipation structure, and the primary entrance and the secondary entrance are connected and arranged staggeredly.

[0052] The primary flow-through wave-dissipation structure and the secondary flow-through wave-dissipation structure are used for wave blocking, and the primary entrance and the secondary entrance are connected and arranged staggeredly to exchange water flow on both sides of the flow-through wave-dissipation dam structure unit, so that the flow-through wave-dissipation dam structure unit can not only exchange water flow on both sides, but also effectively weaken waves.

[0053] The primary entrance and the secondary entrance are arranged staggeredly, that is, in the direction from the primary flow-through wave-dissipation structure to the secondary flow-through wave-dissipation structure, the projection of the primary entrance on the secondary flow-through wave-dissipation structure has no intersection with the secondary entrance. In this way, the wave-dissipation effect is better when water flows through the primary flow-through wave-dissipation structure to the secondary flow-through wave-dissipation structure.

[0054] Preferably, the secondary flow-through wave-dissipation structure also comprises at least one wave-dissipation assembly as described in the present application, the wave-dissipation assembly of the secondary flow-through wave-dissipation structure is arranged correspondingly to the primary entrance, and a wave-dissipation assembly is arranged on at least one side of the secondary entrance.

[0058] Preferably, the inclined guide wall or the normal guide wall and the adjacent side guide wall on the primary through-flow wave dissipating structure form a side port one.

[0059] Preferably, the inclined guide wall or the normal guide wall and the adjacent side guide wall on the primary through-flow wave dissipating structure are connected by a secondary wave blocking wall one, and the secondary wave blocking wall one is located above the side port one.

[0060] Preferably, the side wave dissipating assembly is further provided with an extension part extending outward from the end of the secondary through-flow wave dissipating structure. In general offshore construction conditions, a plurality of through-flow wave dissipating dam structures need to be installed, and in this case, there will be a gap between adjacent through-flow wave dissipating dam structures, which will change the wave dissipating effect of the through-flow wave dissipating dam. Therefore, the side wave dissipating assembly is further provided with an extension part extending outward from the end of the secondary through-flow wave dissipating structure, so as to achieve the effect of shielding the waves passing through the gap.

[0061] Preferably, the side wave dissipating assembly of the secondary through-flow wave dissipating structure is arranged at both ends of the secondary through-flow wave dissipating structure.

The second base is used to expand the cross-sectional area of the bottom of the side wave dissipating assembly, so that it is easier to construct the wave dissipating assembly on the foundation at the bottom later, and also reduces the local bearing stress of the foundation at the bottom.

[0063] Preferably, the side wave dissipating assembly and the wave dissipating assembly are connected by a secondary connecting piece in the secondary through-flow wave dissipating structure.

[0064] The secondary connecting member can only serve as a connecting member between the side wave-eliminating assembly and the wave-eliminating assembly, or can simultaneously serve as a wave-blocking member.

[0065] Preferably, the secondary connecting member comprises a second breast wall, and the side wave-eliminating assembly and the wave-eliminating assembly are connected with the second breast wall, and the second breast wall is located at the top of the secondary flow-through wave-eliminating structure.

[0067] Preferably, the secondary connecting member is connected with the primary flow-through wave-eliminating structure. The secondary connecting member connects the primary flow-through wave-eliminating structure and the secondary flow-through wave-eliminating structure into a whole, and forms a whole cooperative stress mechanism.

[0068] The secondary connecting member comprises a second wave-blocking wall two, and in the secondary flow-through wave-eliminating structure, the side wave-eliminating assembly and the side flow guide wall body of the adjacent wave-eliminating assembly are connected with the second wave-blocking wall two; the top of the second wave-blocking wall two is flush with the wave-eliminating assembly or the top of the second wave-blocking wall two is lower than the top of the wave-eliminating assembly, and the second wave-blocking wall two is located above the secondary port.

[0069] The second wave-blocking wall two can serve as a wave-blocking purpose near the sea surface in daily operation in non-extreme weather, further enhance the wave-blocking effect, and has little influence on the flow passing through the secondary port, and can also serve as a connecting purpose between the side wave-eliminating assembly and the adjacent wave-eliminating assembly, and can enhance the structural stability of the two sides of the secondary port.

[0070] Preferably, the secondary connecting member comprises a connecting structure two, and in the secondary flow-through wave-eliminating structure, the side wave-eliminating assembly and the adjacent wave-eliminating assembly are connected with the connecting structure two, and the connecting structure two is located at the bottom of the secondary port.

[0071] Preferably, the wave-eliminating assembly of the primary flow-through wave-eliminating structure and the wave-eliminating assembly of the secondary flow-through wave-eliminating structure are arranged in the same direction.

[0072] Preferably, the distance from the outer end of the main flow guide wall body of the secondary flow-through wave-eliminating structure to the primary port is T1, and 0≤T1≤2C1, wherein C1 is the width of the primary port, so that the main flow guide wall body of the secondary flow-through wave-eliminating structure can serve as a better flow distribution purpose.

[0073] Preferably, the main flow guide wall of the secondary wave dissipating structure through the primary entrance.

[0074] Preferably, the side wave dissipating component of the secondary wave dissipating structure and the adjacent wave dissipating component of the secondary wave dissipating structure and the wave dissipating component of the adjacent primary wave dissipating structure form a secondary energy dissipation area, which is communicated with a primary entrance and a secondary entrance, and the primary entrance is located at the side of the secondary energy dissipation area away from the primary wave dissipating structure.

[0075] When the water flow or wave passes through the primary entrance, the water flow or wave is divided by the main flow guide wall of the wave dissipating component of the secondary wave dissipating structure near the primary entrance, and part of the water flow or wave enters the secondary energy dissipation area through the gap between the main flow guide wall and the adjacent side flow guide wall of the primary wave dissipating structure, and then part of the water flow or wave entering the secondary energy dissipation area changes direction through the intersection of the main flow guide wall and the side flow guide wall after running a distance along the main flow guide wall, and flows to the secondary entrance, and the speed of this part of the water flow or wave is fast, while the speed of the water flow or wave at the middle position of the secondary energy dissipation area is very slow, and the high-speed water flow or wave will drive the water flow or wave at the middle position of the bin to rotate, so that strong vortex and water flow turbulence are formed in the secondary energy dissipation area, so that the secondary energy dissipation area becomes an energy dissipation pool, and the wave dissipates energy in the secondary energy dissipation area, thereby achieving the purpose of reducing wave height.

[0076] Preferably, the side wave dissipating component and the adjacent wave dissipating component of the primary wave dissipating structure form a side entrance one, and the side entrance one is communicated with the adjacent secondary energy dissipation area. Part of the water flow or wave passing through the side entrance one runs along the inner wall of the side wave dissipating component close to the secondary energy dissipation area and flows to the secondary entrance, and the speed of this part of the water flow or wave is fast, while the speed of the water flow or wave at the middle position of the secondary energy dissipation area is very slow, and the high-speed water flow or wave will drive the water flow or wave at the middle position of the bin to rotate, so that strong vortex and water flow turbulence are formed in the secondary energy dissipation area, so that the secondary energy dissipation area becomes an energy dissipation pool, and the wave dissipates energy in the secondary energy dissipation area, thereby achieving the purpose of reducing wave height.

[0077] When the water flow of the primary entrance and the side entrance one all enters the secondary energy dissipation area, at least two strong vortexes and water flow turbulence are formed in the secondary energy dissipation area with a high probability, so that the energy dissipation effect of the secondary energy dissipation area is better, and the wave dissipating effect of the wave dissipating dam structure unit of the application is better.

[0079] Preferably, the wave dissipation component of the primary flow-through wave dissipation structure is arranged corresponding to the secondary entrance, and the included angle opening formed by the two side flow guide walls of the wave dissipation component of the primary flow-through wave dissipation structure faces the secondary entrance.

[0080] The above scheme makes the channel between the primary entrance and the secondary entrance into a similar "N" type, and through the "N" type channel, the wave propagation path and tortuosity are increased, so as to consume wave energy and reduce wave height.

[0081] At the same time, through the "N" type channel, it is difficult for waves to pass through, and part of the waves or exist reflection, which is reflected multiple times in the channel between the primary flow-through wave dissipation structure and the secondary flow-through wave dissipation structure and finally forms a water column with a higher water level, not only enhancing the energy consumption effect of the waves in the "N" type channel, but also increasing the pressure of the water flow on the lower foundation, and at the same time, the above waves or water flow generate a large reverse wave pressure to offset part of the positive wave pressure of the waves or water flow on the primary flow-through wave dissipation structure away from the secondary flow-through wave dissipation structure side.

[0082] Moreover, when the flow-through wave dissipation dam structure unit is used as a large-scale marine ranching wave dissipation dam, the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the flow-through wave dissipation dam structure unit from the rear end of the flow-through wave dissipation dam structure unit located at the far end, based on the same energy consumption mechanism, the flow-through wave dissipation dam structure unit can better reduce wave reflection and greatly reduce or avoid the probability of wave resonance in the ranching.

[0083] The above form of the flow-through wave dissipation dam structure unit can meet the flow-through wave dissipation purpose in the water depth of 80 m or less marine environment, and the primary flow-through wave dissipation structure has a wave dissipation component corresponding to the secondary entrance, so as to avoid the direct impact of the waves on the secondary entrance and cause the flow-through wave dissipation dam structure unit not to meet the wave dissipation condition.

[0084] On the basis of the above, compared with the existing wave dissipation dam with a cylinder from top to bottom and the existing caisson type vertical dam, the wave dissipation dam structure unit disclosed by the application effectively reduces the cost. Moreover, the number of adjustable structure parameters for different sea conditions is much larger than that of the existing wave dissipation dam with a cylinder from top to bottom, so that the special needs in different working conditions can be better met, and the wave dissipation dam structure unit has better performance-price ratio in the corresponding working conditions. The wave dissipation dam structure unit disclosed by the application has a light structure, and is generally a caisson compared with the traditional vertical dam. The structure above the foundation of the wave dissipation dam structure unit disclosed in the embodiment mainly includes several wall bodies, and has a higher performance-price ratio and a more sustainable development scheme.

[0087] Preferably, the primary wave dissipation structure and the secondary wave dissipation structure are alternately arranged in the direction from the secondary wave dissipation structure to the primary wave dissipation structure.

[0088] Preferably, the wave dissipation components in at least part of the secondary wave dissipation structure are arranged in the same direction as the wave dissipation components in the primary wave dissipation structure adjacent to at least one side.

[0089] Preferably, the wave dissipation components in at least part of the secondary wave dissipation structure are arranged in the opposite direction to the wave dissipation components in the primary wave dissipation structure adjacent to at least one side.

The primary port door and the secondary port door are arranged in a staggered manner, and the secondary port door is arranged in a staggered manner, so that the water flow exchange on both sides of the wave dissipation dam structure unit can be realized, and the wave dissipation dam structure unit can effectively weaken the waves.

In this way, the wave-dissipating effect is better when the water flow passes through the second-level flow-permeating and wave-dissipating structure and the third-level flow-permeating and wave-dissipating structure.

[0101] After the water flow or wave passes through the secondary port, it enters the tertiary energy consumption area. A part of the water flow or wave that enters the tertiary energy consumption area flows a distance along the side flow guide wall and then changes direction at the junction of the side flow guide wall and the main flow guide wall, and flows to the tertiary port. The water flow or wave has a high speed, while the water flow or wave at the middle position of the tertiary energy consumption area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the bin to rotate, so that strong vortexes and water flow turbulence are formed in the tertiary energy consumption area, thereby making the tertiary energy consumption area an energy consumption pool. The wave consumes energy in the tertiary energy consumption area, thereby achieving the purpose of reducing the wave height.

[0102] Preferably, a side port two is formed between the side wave dissipation component on the secondary flow-through wave dissipation structure and the adjacent wave dissipation component on the tertiary flow-through wave dissipation structure, and the side port two is connected with the adjacent tertiary energy consumption area.

[0103] After the water flow or wave passes through the secondary port, it enters the tertiary energy consumption area. A part of the water flow or wave that enters the tertiary energy consumption area flows a distance along the side wave dissipation component and then flows to the side port two. The water flow or wave has a high speed, while the water flow or wave at the middle position of the tertiary energy consumption area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the bin to rotate, so that strong vortexes and water flow turbulence are formed in the tertiary energy consumption area, thereby making the tertiary energy consumption area an energy consumption pool. The wave consumes energy in the tertiary energy consumption area, thereby achieving the purpose of reducing the wave height.

[0104] Moreover, after the water flow or wave passes through the secondary port, it enters the tertiary energy consumption area. A part of the water flow or wave flows along the wave dissipation component to the tertiary port, and a part of the water flow or wave flows a distance along the side wave dissipation component on the other side and then flows to the side port two. With a high probability, at least two strong vortexes and water flow turbulence are formed in the secondary energy consumption area, thereby making the energy consumption effect of the tertiary energy consumption area better, and thereby making the wave dissipation effect of the flow-through wave dissipation dam structure unit of the present application better.

[0110] The above-mentioned scheme makes the passage between the secondary port gate and the tertiary port gate into a similar "N" type, and through the "N" type passage, the wave propagation path and tortuosity are increased, so as to consume wave energy and reduce wave height.

[0111] Meanwhile, through the "N" type passage, it is difficult for waves to pass through, and part of the waves are reflected, forming a water column with a higher water level in the passage between the tertiary wave dissipating and permeating structure and the secondary wave dissipating and permeating structure. This not only enhances the energy consumption effect of the waves in the "N" type passage, but also increases the pressure of the water flow on the lower foundation. Meanwhile, the above-mentioned waves or water flow generate a large reverse wave pressure to offset part of the positive wave pressure of the waves or water flow on the secondary wave dissipating and permeating structure away from the side of the tertiary wave dissipating and permeating structure.

[0112] Moreover, when the wave dissipating and permeating dam structure unit is used as a large-scale marine ranching wave dissipating dam, after the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the wave dissipating and permeating dam structure unit from the rear end of the wave dissipating and permeating dam structure unit located at the far end, based on the same energy consumption mechanism, the wave dissipating and permeating dam structure unit can better reduce wave reflection, greatly reduce or avoid the probability of wave resonance in the ranching.

In this way, the wave-damping effect of the water flow passing through the third wave-permeable wave-damping structure to the fourth wave-permeable wave-damping structure is better.

[0136] Preferably, the wave absorbing assembly of the fourth through-flow wave absorbing structure and the wave absorbing assembly of the third through-flow wave absorbing structure are arranged in the same direction.

[0137] Preferably, the main guide wall body of the fourth through-flow wave absorbing structure points to the third port.

[0138] Preferably, the distance from the outer end of the main guide wall body of the fourth through-flow wave absorbing structure to the third port is T3, and 0≤T3≤2C3, wherein C3 is the width of the third port, so that the main guide wall body of the fourth through-flow wave absorbing structure can play a better flow distribution purpose.

[0139] Preferably, the main guide wall body of the fourth through-flow wave absorbing structure penetrates the third port.

[0140] Preferably, the side wave absorbing assembly of the fourth through-flow wave absorbing structure, the adjacent wave absorbing assembly in the fourth through-flow wave absorbing structure, and the wave absorbing assembly in the adjacent third through-flow wave absorbing structure enclose a fourth energy consumption area, and the third port and the fourth port are communicated in the fourth energy consumption area.

[0141] When the water flow or wave passes through the third level port door, the water flow or wave is divided by the main flow wall of the wave dissipation assembly of the fourth level flow-through wave dissipation structure near the third level port door, a part of the water flow or wave enters the fourth level energy dissipation area through the gap between the main flow wall and the adjacent side flow wall of the third level flow-through wave dissipation structure, and then a part of the water flow or wave that enters the fourth level energy dissipation area changes direction through the intersection of the main flow wall and the side flow wall after flowing along the main flow wall for a distance, and flows to the fourth level port door. The water flow or wave has a high speed, while the water flow or wave at the middle position of the fourth level energy dissipation area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the tank to rotate, so that strong vortexes and water flow turbulence are formed in the fourth level energy dissipation area, so that the fourth level energy dissipation area becomes an energy dissipation pool. The wave dissipates energy in the fourth level energy dissipation area, thereby achieving the purpose of reducing the wave height.

[0142] Preferably, a side port door three is formed between the side wave dissipation assembly and the wave dissipation assembly on the adjacent third level flow-through wave dissipation structure, and the side port door three is connected with the adjacent fourth level energy dissipation area.

[0143] A part of the water flow or wave passing through the side port door three flows along the side wave dissipation assembly close to the inner wall of the fourth level energy dissipation area and flows to the fourth level port door. The water flow or wave has a high speed, while the water flow or wave at the middle position of the fourth level energy dissipation area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the tank to rotate, so that strong vortexes and water flow turbulence are formed in the fourth level energy dissipation area, so that the fourth level energy dissipation area becomes an energy dissipation pool. The wave dissipates energy in the fourth level energy dissipation area, thereby achieving the purpose of reducing the wave height.

[0144] When the water flow of the third level port door and the side port door three all enters the fourth level energy dissipation area, at least two strong vortexes and water flow turbulence are formed in the fourth level energy dissipation area with a high probability, so that the energy dissipation effect of the fourth level energy dissipation area is better, and the wave dissipation effect of the flow-through wave dissipation dam structure unit is better.

[0145] Preferably, a fourth level wave blocking wall two is connected between the side wave dissipation assembly and the adjacent side flow wall of the third level flow-through wave dissipation structure, and the fourth level wave blocking wall two is located above the side port door three.

[0146] The fourth level wave blocking wall two can play a wave blocking role near the sea surface, further enhance the wave blocking effect, and has little effect on the water flow passing through the side port door three. At the same time, the fourth level wave blocking wall two can also play a connecting role between the side wave dissipation assembly and the adjacent side flow wall of the third level flow-through wave dissipation structure, and enhance the structural stability of the two sides of the side port door one.

[0147] Preferably, the main flow wall of the third level flow-through wave dissipation structure points to the fourth level port door.

[0148] Preferably, the wave dissipation component of the fourth-level flow-through wave dissipation structure and the adjacent wave dissipation component in the third-level flow-through wave dissipation structure form a fourth-level energy dissipation area, which is communicated with a third-level port and at least two fourth-level ports.

[0149] After the water flow or wave passes through the third-level port and enters the fourth-level energy dissipation area, a part of the water flow or wave flows along the side guide wall of one side wave dissipation component for a distance and then changes direction at the intersection of the side guide wall and the main guide wall to flow to the fourth-level port on the same side. The water flow or wave has a high speed, while the water flow or wave at the middle position in the fourth-level energy dissipation area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position in the bin to rotate, so that strong vortexes and water flow turbulence are formed in the fourth-level energy dissipation area. Thus, the fourth-level energy dissipation area becomes an energy dissipation pool, and the wave dissipates energy in the fourth-level energy dissipation area, thereby achieving the purpose of reducing wave height.

[0150] Meanwhile, a part of the water flow or wave flows along the side guide wall of the other side wave dissipation component for a distance and then changes direction at the intersection of the side guide wall and the main guide wall to flow to the fourth-level port on the same side. The water flow or wave has a high speed, while the water flow or wave at the middle position in the fourth-level energy dissipation area has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position in the bin to rotate, so that strong vortexes and water flow turbulence are formed in the fourth-level energy dissipation area. Thus, the fourth-level energy dissipation area becomes an energy dissipation pool, and the wave dissipates energy in the fourth-level energy dissipation area, thereby achieving the purpose of reducing wave height.

[0151] In summary, after the water flow or wave passes through the third-level port and enters the fourth-level energy dissipation area, it will most probably form at least two strong vortexes and water flow turbulence in the fourth-level energy dissipation area in the process of reaching the at least two fourth-level ports. Thus, the energy dissipation effect of the fourth-level energy dissipation area is better, and the wave dissipation effect of the flow-through wave dissipation dam structure unit of the present application is better.

[0152] Preferably, the included angle opening formed by the two side guide walls of the wave dissipation component of the fourth-level flow-through wave dissipation structure faces the third-level port.

[0153] Preferably, the wave dissipation component of the third-level flow-through wave dissipation structure is correspondingly arranged with the fourth-level port, and the included angle opening formed by the two side guide walls of the wave dissipation component of the third-level flow-through wave dissipation structure faces the fourth-level port.

[0154] The above scheme makes the channel between the third-level port and the fourth-level port have a shape similar to an "N". Through the "N"-shaped channel, the wave propagation path and tortuosity are increased, thereby achieving the purposes of dissipating wave energy and reducing wave height.

[0155] Meanwhile, through the "N" type channel, it is difficult for waves to pass through easily, and part of the waves or exist reflection, which forms a higher water column in the channel between the three-level flow-through wave dissipation structure and the four-level flow-through wave dissipation structure, not only enhances the energy dissipation effect of the waves in the "N" type channel, but also increases the pressure of the water flow on the lower foundation, while the above-mentioned waves or water flow generates a larger reverse wave pressure to offset part of the positive wave pressure of the three-level flow-through wave dissipation structure on the side away from the four-level flow-through wave dissipation structure.

[0156] And when the above-mentioned flow-through wave dissipation dam structure unit is used as a large-scale marine ranching wave dissipation dam, the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the flow-through wave dissipation dam structure unit from the rear end of the flow-through wave dissipation dam structure unit located at the far end, based on the same energy dissipation mechanism, the flow-through wave dissipation dam structure unit can better reduce wave reflection and greatly reduce or avoid the probability of wave resonance in the ranching.

[0157] The above-mentioned form of the flow-through wave dissipation dam structure unit can meet the flow-through wave dissipation purpose in the water depth of 80m or less marine environment, and the three-level flow-through wave dissipation structure has a wave dissipation component corresponding to the four-level port to avoid the situation that the flow-through wave dissipation dam structure unit does not meet the wave dissipation due to the direct impact of the waves on the four-level port.

[0158] Based on the above, compared with the existing wave dissipation dam with a cylinder from top to bottom and the existing sunk box type vertical dam, the flow-through wave dissipation dam structure unit can effectively reduce the cost. Moreover, the number of adjustable structure parameters for different sea conditions is much larger than that of the existing wave dissipation dam with a cylinder from top to bottom, so that it can better meet the special needs under different working conditions and have better cost performance under corresponding working conditions.

[0159] The flow-through wave dissipation dam structure unit has a light structure, and compared with the traditional vertical dam which is generally a sunk box, the structure above the foundation of the flow-through wave dissipation dam structure unit mainly includes several wall bodies, which has a higher cost performance and a more sustainable development scheme.

The width gradually decreases from wide to narrow, and the wave energy dissipation effect is better, the wave force is smaller, the reflection is smaller, and the transmission effect is basically the same.

[0282] Embodiment 1

[0283] As shown in FIGS. 1-8, the wave dissipating assembly described in the embodiment comprises a main guide wall 11 and two side guide walls 12 connected in a radial manner.

[0284] The included angle A between the main guide wall 11 and one of the side guide walls 12 ranges from 90° to 180°, and the included angle B between the main guide wall 11 and the other side guide wall 12 ranges from 90° to 180°.

[0285] The wave dissipating assembly described in the embodiment can change the flow direction of the water flow near the main guide wall 11 by setting the main guide wall 11, and can make the water accumulate outside the main guide wall 11, which is more conducive to the water flow outside the main guide wall 11 and the side guide wall 12 to pass through the wave dissipating assembly from both sides of the wave dissipating assembly.

[0286] When the wave impacts the wave dissipating assembly along the main guide wall 11, the wave changes its direction twice and simultaneously changes its propagation speed at the main guide wall 11 and the junction of the main guide wall 11 and the side guide wall 12, and then continues to propagate forward at the end of the side guide wall 12

in the direction away from the main guide wall 11

[0287] When the water flow moves obliquely along the main guide wall 11 to the vicinity of the wave dissipating assembly, the main guide wall 11 can effectively capture the water flow passing through the wave dissipating assembly from one side of the wave dissipating assembly in the direction of the main guide wall 11 and the side guide wall 12.

[0288] When the wave obliquely impacts the wave dissipating assembly along the main guide wall 11, the wave changes its direction twice at the main guide wall 11 and the junction of the main guide wall 11 and the side guide wall 12, and then continues to propagate forward at the end of the side guide wall 12

in the direction away from the main guide wall 11

[0289] As shown in Figure 2, on the basis of the above scheme, the wave-eliminating assembly described in the present application is in the case that the water flow flows to the rear of the wave-eliminating assembly along the main guide wall 11 and the side guide wall 12 on both sides of the main guide wall 11, the wave force of the wave on the two side guide walls 12 is perpendicular to the side guide wall 12, and the wave force of the water flow on the two side guide walls 12 in the direction perpendicular to the main guide wall 11 (referred to as the X direction) can be offset or most of it can be offset, thereby greatly optimizing the stress condition of the wave-eliminating assembly in the direction perpendicular to the main guide wall 11, so that only the wave force in the direction along the main guide wall 11 (referred to as the Y direction) needs to be focused on during design and use, thereby enabling the wave-eliminating assembly described in the present application to be used in the open sea with a water depth of 20-80 m.

[0290] Moreover, the relative positions of the main guide wall 11 and the two side guide walls 12 are arranged in a similar "Y" shape, and the bending resistance coefficient of the cross section in any direction is much larger than that of a single wall structure, and the strength-to-weight ratio is higher than that of a rectangular closed cross section of a traditional caisson structure, and the ability to resist instability and control deformation is stronger than that of a single pile or plate structure, thereby providing sufficient structural support for the wave-eliminating assembly described in the present application to be used in the open sea with a water depth of 20-80 m.

[0291] Meanwhile, the relative positions of the main guide wall 11 and the two side guide walls 12 are arranged in a similar "Y" shape, so that the overall gravity of the wave-eliminating assembly described in the present application is relatively balanced, and the vertical gravity center of the wave-eliminating assembly can fall within the range of the similar triangle 71 formed by the end of the main guide wall 11 and the ends of the two side guide walls 12, thereby eliminating the need to set up a large hoisting frame and a balance weight on the upper part of the wave-eliminating assembly during construction to hoist the wave-eliminating assembly, which greatly saves the hoisting cost compared with a wave-eliminating structure with a larger eccentricity, thereby greatly reducing the construction cost.

[0292] The wave-eliminating assembly described in the present embodiment is light in structure, and compared with a large barrel dam and a traditional caisson vertical dam, the wave-eliminating assembly described in the present embodiment mainly comprises several wall bodies, has a higher cost performance, and is a more sustainable development scheme.

[0293] It is worth noting that the wave-eliminating assembly described in the present embodiment can also be used to block waves in the opposite direction, and in some cases, the wave or water flow will flow to the wave-eliminating assembly from the side of the side guide wall 12 away from the main guide wall 11 during use, for example, when it is arranged outside the offshore aquaculture farm, the water flow in the aquaculture farm will flow in the direction from the upper side guide wall 12 to the main guide wall 11 to flow out of the aquaculture farm, at this time, the wave-eliminating assembly also has the function of partially allowing the flow to pass through and eliminating the wave.

[0294] In summary, the wave-eliminating assembly described in the embodiment reduces the total wave force under the condition of the same wave transmission coefficient as a single wave-eliminating assembly. The solid cylinder structure is optimized to a plate-shaped distributed space structure. The main flow guide wall 11 arranged at the front end of the unit guides the sea current, effectively reducing the cost control disadvantage caused by the method of increasing the additional flow guide unit group through the total plane optimization of the front sequence patent.

[0295] As shown in FIG. 4, the included angle A and the included angle B can be different, for example, the included angle A is 110°, and the included angle B is 130°. The main flow guide wall 11 and the side flow guide wall 12 are not uniformly arranged, and the lengths of the two side flow guide walls 12 can be different. The lengths of the side flow guide walls 12 and the length of the main flow guide wall 11 can also be different, for example, A=B, and the lengths of the two side flow guide walls are different; or A≠B, and the lengths of the two side flow guide walls are different.

[0296] The size relationship between the included angle A and the included angle B can also be A=B±10°. More preferably, the size relationship between the included angle A and the included angle B is A=B±5°. At this time, the lengths of the two side flow guide walls 12 can be different, but the more preferred choice is that the two side flow guide walls 12 are symmetrically arranged relative to the main flow guide wall 11.

[0297] The angle range of the included angle A is preferably 110°≤A≤135°.

[0298] The angle range of the included angle B is preferably 110°≤B≤135°.

[0299] The two side flow guide walls 12 can be arranged perpendicular to each other.

[0300] Further, the main flow guide wall 11, the side flow guide wall 12, and the third flow guide wall 13 are circumferentially uniformly arranged. At this time, A=B=120°.

[0301] As shown in FIG. 3, the outer end of the main flow guide wall 11 is provided with a guide round portion 15 or a chamfer portion 16.

[0302] As shown in FIG. 3, the outer end of the side flow guide wall 12 is provided with a guide round portion 15 or a chamfer portion 16.

[0303] As shown in FIG. 5, the main flow guide wall 11 is further connected with a first arm 14. The first arm 14 is located between the side flow guide wall 12 and the third flow guide wall 13, further enhancing the turbulence of the water body between the two side flow guide walls 12.

[0304] The main flow guide wall 11 and the two side flow guide walls 12 can be connected, for example, connected by a connecting member after being separately prefabricated, or connected together by cast-in-place, and in more cases, the main flow guide wall 11 and the two side flow guide walls 12 are integrally formed. For example, integrally poured and formed by using reinforced concrete, which has better overall bearing capacity.

[0305] As shown in FIGS. 1-6, the main flow guide wall 11 is a plate structure.

[0306] As shown in FIGS. 1-6, the side flow guide wall 12 is a plate structure.

[0307] As shown in FIG. 6, a preferred scheme is that the root wall thickness of the main flow guide wall 11 is greater than the outer end wall thickness, so that the structure of the main flow guide wall 11 is more optimized according to the force.

[0308] The root wall thickness of the side flow guide wall 12 is greater than the outer end wall thickness, so that the structure of the side flow guide wall 12 is more optimized according to the force.

[0309] As shown in FIG. 7, a further preferred scheme is that the main flow guide wall 11 is provided with a through hole 13 to reduce the wave force on the main flow guide wall 11. The side flow guide wall 12 is provided with a through hole 13 to reduce the wave force on the side flow guide wall 12.

[0310] As shown in FIG. 8, the main flow guide wall 11 is provided with a first base 65 at the bottom, and the side of the first base 65 protrudes from the main flow guide wall 11. The side flow guide wall 12 is provided with a first base 65 at the bottom, and the side of the first base 65 partially or entirely protrudes from the side flow guide wall 12. The cross-sectional area of the bottom of the wave dissipation assembly is expanded to optimize the force on the bottom of the main flow guide wall 11. If it is necessary to install the wave dissipation assembly on the foundation 5 at the bottom without being integrally prefabricated with the foundation 5 at the bottom, the first base 65 can also make it easier to construct the wave dissipation assembly on the foundation 5 at the bottom later, and reduce the local bearing stress of the foundation 5 at the bottom.

[0311] The first base 65 is preferably a concrete structure, and the cross-sectional shape is similar to that of the main flow guide wall 11 and / or the side flow guide wall 12. The width of the first base 65 is wider than that of the main flow guide wall 11 and / or the side flow guide wall 12, and the first base 65 can be integrally poured and formed with the main flow guide wall 11 and the side flow guide wall 12.

[0313] As shown in FIG. 9, the flow-through wave-damping dam construction unit according to the embodiment comprises a first flow-through wave-damping structure 1, wherein the first flow-through wave-damping structure 1 comprises at least one wave-damping assembly 8 according to the embodiment 1, and a first port 17 is arranged through the first flow-through wave-damping structure 1 for water flow, and at least one side of the wave-damping assembly 8 is provided with the first port 17.

[0314] The flow-through wave-damping dam construction unit according to the embodiment of the application can be used to reduce the wave height and achieve better wave-damping effect.

[0315] When the wave impacts the wave-damping assembly along the main flow guide wall 11, the wave is secondarily diverted at the main flow guide wall 11 and the junction of the main flow guide wall 11 and the side flow guide wall 12, and then continues to propagate forward at the end of the side flow guide wall 12 (away from the main flow guide wall 11, at least one side passing through the first port 17). Since the water body after being guided and accelerated has different direction and speed potential from the water body behind the first flow-through wave-damping structure 1, the water body after fusion can produce strong turbulence, and the damping wave-damping effect similar to the "moon pool" provides favorable conditions, so that the flow-through wave-damping dam construction unit according to the application can be used to reduce the wave height and achieve better wave-damping effect.

[0316] When the water flow moves obliquely along the main flow guide wall 11 to the vicinity of the wave-damping assembly, the main flow guide wall 11 can effectively capture the water flow passing through the wave-damping assembly from one side of the wave-damping assembly in the direction of the main flow guide wall 11 and the side flow guide wall 12,

[0317] When the wave impacts the wave-damping assembly along the main flow guide wall 11, the wave is secondarily diverted at the main flow guide wall 11 and the junction of the main flow guide wall 11 and the side flow guide wall 12, and then continues to propagate forward at the end of the side flow guide wall 12 (away from the main flow guide wall 11, at least one side passing through the first port 17). Since the water body after being guided and accelerated has different direction and speed potential from the water body behind the first flow-through wave-damping structure 1, the water body after fusion can produce strong turbulence, and the damping wave-damping effect similar to the "moon pool" provides favorable conditions, so that the flow-through wave-damping dam construction unit according to the application can be used to reduce the wave height and achieve better wave-damping effect.

[0318] The first flow-through wave-damping structure 1 comprises at least two wave-damping assemblies 8, and a first port 17 is formed between adjacent wave-damping assemblies 8.

[0319] As shown in FIG. 9, in a preferred scheme, adjacent wave-damping assemblies 8 are arranged in the same direction.

[0320] Specifically, the primary port 17 in the primary permeable wave dissipating structure 1 is formed by the side flow guide wall 12 of the adjacent wave dissipating assembly 8.

[0321] The main flow guide wall 11 of the adjacent wave dissipating assembly 8 and the opposite side flow guide wall 12 of the adjacent wave dissipating assembly 8 form a primary energy dissipation area 10, and the width of the primary energy dissipation area 10 from the junction of the main flow guide wall 11 and the side flow guide wall 12 to the primary port 17 is continuously narrowed.

[0322] When the wave or water flow reaches the primary permeable wave dissipating structure 1, part of the wave or water flow enters the primary energy dissipation area 10, and another part of the wave or water flow is effectively captured by the main flow guide wall 11 into the primary energy dissipation area 10 and moves along the main flow guide wall 11 towards the primary port 17. In this process, part of the wave moves along the main flow guide wall 11 and changes direction again at the junction of the main flow guide wall 11 and the side flow guide wall 12. The above process causes the water flow in different areas of the primary energy dissipation area 10 to have different speeds and directions, thereby forming water flow rotation under certain working conditions, thereby achieving the purpose of weakening the wave. At the same time, since the width of the primary energy dissipation area 10 from the junction of the main flow guide wall 11 and the side flow guide wall 12 to the primary port 17 is continuously narrowed, the water level in the primary energy dissipation area 10 increases when the water flow moves towards the primary port 17, thereby increasing the water volume and speed of the water flow through the primary port 17 per unit time, and thereby effectively increasing the permeable effect of the permeable wave dissipating dam structure unit.

[0323] As shown in FIG. 9, the main flow guide walls 11 of the two wave dissipating assemblies 8 are both directed in one direction, and the openings formed by the two side flow guide walls 12 are also directed in the same direction, i.e., the adjacent wave dissipating assemblies 8 are arranged in the same direction.

[0324] A preferred scheme is that the adjacent wave dissipating assemblies 8 in the primary permeable wave dissipating structure 1 are connected. The connecting member connecting the adjacent wave dissipating assemblies 8 can only be used for connection, such as a rod structure, and if other purposes are considered, the specific scheme is preferably at least one of the following schemes:

[0325] As shown in FIGS. 11-13, a specific scheme one is that the first parapet 19 is connected between the adjacent wave dissipating assemblies 8 in the primary permeable wave dissipating structure 1, and the first parapet 19 is located at the top of the wave dissipating assembly 8, and the upper part of the first parapet 19 protrudes upwards beyond the wave dissipating assembly 8.

[0326] The first parapet 19 can be connected to the side flow guide wall 12 of the adjacent wave dissipating assembly 8, or can be connected to the main flow guide wall 11 of the adjacent wave dissipating assembly 8, or can be connected to both the side flow guide wall 12 and the main flow guide wall 11 of the adjacent wave dissipating assembly 8.

[0327] When the first parapet 19 is arranged above the high water level as a wave blocking structure, the wave is further reduced, but the water flow exchange in the daily operation under non-extreme weather is not affected, and the connection between the wave dissipating components 8 on both sides can also enhance the stability of the wave dissipating components 8 on both sides of the primary entrance 17.

[0328] As shown in FIG. 14, in a specific scheme two, the first wave dissipating structure 1 is connected with a first wave blocking wall 110 between the side flow guide walls 12 of adjacent wave dissipating components 8; the first wave blocking wall 110 is located at the top of the primary entrance 17, and plays a role of blocking waves near the sea surface under the daily operation in non-extreme weather, further enhances the wave blocking effect, and has little effect on the water flow passing through, and can also play a role of connecting between the wave dissipating components 8 on both sides, thereby enhancing the stability of the wave dissipating components 8 on both sides of the primary entrance 17. The first wave blocking wall 110 can be a solid or hollow plate.

[0329] As shown in FIG. 13, in a specific scheme three, the first wave dissipating structure 1 further comprises a connecting structure one 61, the first wave dissipating structure 1 is connected with the connecting structure one 61 between adjacent wave dissipating components 8, and the connecting structure one 61 is located at the bottom of the primary entrance 17. The connecting structure one 61 can play a role of connecting between the wave dissipating components 8 on both sides, thereby enhancing the stability of the wave dissipating components 8 on both sides of the primary entrance 17, and can also play a role of enclosing when filling with rubble or other structures at the lower part of the first wave dissipating structure 1.

[0330] The connecting structure one 61 can be connected to the side flow guide wall 12 of the adjacent wave dissipating component 8, or can be connected to the main flow guide wall 11 of the adjacent wave dissipating component 8, or can be connected to both the side flow guide wall 12 and the main flow guide wall 11 of the adjacent wave dissipating component 8.

[0331] Specifically, the connecting structure one 61 can be a plate or a box girder component.

[0332] As shown in FIG. 10, in a preferred scheme, the projection of the main flow guide wall 11 to the same side of the side flow guide wall 12 of the adjacent wave dissipating component 8 covers the root of the side flow guide wall 12. In this way, the air entrainment caused by the oblique incident wave impacting the side flow guide wall 12 in the direction perpendicular to the wall surface of the side flow guide wall 12 can be effectively reduced or eliminated, thereby reducing the stress of the wave on the side flow guide wall 12.

[0333] In a preferred scheme, the first base 65 at the bottom of the wave dissipating component 8 is connected and integrally arranged.

[0334] Embodiment 3

[0335] As shown in FIGS. 16 and 17, the application also discloses a flow-through wave-damping dam construction unit, which is different from the embodiment 2 in that the first flow-through wave-damping structure 1 is provided with a second flow-through wave-damping structure 2 near one side of the side flow guide wall 12, wherein the second flow-through wave-damping structure 2 is provided with a second port 27, and the first port 17 and the second port 27 are connected and staggered.

[0336] The first flow-through wave-damping structure 1 and the second flow-through wave-damping structure 2 are used to block waves, and the first port 17 and the second port 27 are connected to exchange water flow on both sides of the flow-through wave-damping dam construction unit. The staggered arrangement of the first port 17 and the second port 27 can not only exchange water flow on both sides of the flow-through wave-damping dam construction unit, but also effectively weaken waves.

[0337] The first port 17 and the second port 27 are staggered, that is, the projection of the first port 17 to the second flow-through wave-damping structure 2 does not intersect with the second port 27 in the direction from the first flow-through wave-damping structure 1 to the second flow-through wave-damping structure 2. In this way, the wave-damping effect of the water flow through the first flow-through wave-damping structure 1 to the second flow-through wave-damping structure 2 is better.

[0338] The second flow-through wave-damping structure 2 also includes at least one wave-damping assembly 8 as described in the embodiment 1.

[0339] In a preferred embodiment, the wave-damping assembly 8 of the second flow-through wave-damping structure 2 is arranged corresponding to the first port 17, and at least one side of the second port 27 is provided with a wave-damping assembly 8.

[0340] The second flow-through wave-damping structure 2 includes a wave-damping assembly 8 and a side wave-damping assembly 25.

[0341] The wave-damping assembly 8 of the second flow-through wave-damping structure 2 is at least one, and one wave-damping assembly 8 is taken as an example:

[0342] In the second flow-through wave-damping structure 2, at least one side of the wave-damping assembly 8 is provided with a side wave-damping assembly 25, and the side wave-damping assembly 25 and the wave-damping assembly 8 form the second port 27.

[0343] Further, in the second flow-through wave-damping structure 2, both sides of the wave-damping assembly 8 are provided with a side wave-damping assembly 25, and the side wave-damping assembly 25 and the wave-damping assembly 8 form the second port 27.

[0344] If the wave-damping assembly 8 in the second flow-through wave-damping structure 2 is at least two, the second port 27 is also formed between adjacent wave-damping assemblies 8.

[0345] The side wave dissipating assembly 25 of the secondary permeable wave dissipating structure 2 is arranged at both ends of the secondary permeable wave dissipating structure 2.

[0346] As shown in FIG. 29, specifically, the side wave dissipating assembly 25 comprises a connected inclined flow guide wall 26 and a normal flow guide wall 28, the normal flow guide wall 28 is arranged in the same direction as the main flow guide wall 11 of the secondary permeable wave dissipating structure 2, and the inclined flow guide wall 26 is inclined towards the side flow guide wall 12 of the adjacent wave dissipating assembly 8 of the secondary permeable wave dissipating structure 2, and the inclined flow guide wall 26 and the adjacent side flow guide wall 12 of the secondary permeable wave dissipating structure 2 form the secondary port 27.

[0347] The side wave dissipating assembly 25 and the wave dissipating assembly 8 on the adjacent primary permeable wave dissipating structure 1 form a side port 20.

[0348] As shown in FIG. 20, more specifically, when the inclined flow guide wall 26 is close to the primary permeable wave dissipating structure 1, the inclined flow guide wall 26 and the adjacent side flow guide wall 12 of the primary permeable wave dissipating structure 1 form a side port 20. Under this scheme, a preferred way is that the inclined flow guide wall 26 and the adjacent side flow guide wall 12 of the primary permeable wave dissipating structure 1 are connected by a secondary wave retaining wall 24, the secondary wave retaining wall 24 is located above the side port 20, and the secondary wave retaining wall 24 can protrude upwards from the inclined flow guide wall 26 or not.

[0349] When the normal flow guide wall 28 is close to the primary permeable wave dissipating structure 1, the normal flow guide wall 28 and the adjacent side flow guide wall 12 of the primary permeable wave dissipating structure 1 form a side port 20. The normal flow guide wall 28 and the adjacent side flow guide wall 12 of the primary permeable wave dissipating structure 1 are connected by a secondary wave retaining wall 24, the secondary wave retaining wall 24 is located above the side port 20, and the secondary wave retaining wall 24 can protrude upwards from the normal flow guide wall 28 or not.

[0350] As shown in FIG. 18, a preferred way is that the side wave dissipating assembly 25 is also provided with an extension 7 extending outward from the end of the secondary permeable wave dissipating structure 2. Under general offshore construction conditions, multiple permeable wave dissipating dam structures need to be installed, and in this case, there will be a gap between adjacent permeable wave dissipating dam structures, which will affect the wave dissipating effect of the permeable wave dissipating dam. Therefore, the extension 7 extending outward from the end of the secondary permeable wave dissipating structure 2 is arranged in the side wave dissipating assembly 25, so that it can achieve a certain effect of dissipating water flow through the gap.

[0351] The extension 7 is preferably a plate structure or a frame outer side covering panel combination structure.

[0352] As shown in Figs. 29 and 30, specifically, the extension 7 is connected with the inclined or normal flow guide wall 26 or 28. It is arranged at the waist or end of the side wave dissipating assembly 25.

[0353] As shown in Fig. 31, in a preferred manner, the bottom of the side wave dissipating assembly 25 is provided with a second base 66, the top of which is connected with or integrally arranged with the side wave dissipating assembly 25, and the second base 66 at least partially laterally protrudes from the side wave dissipating assembly 25. The second base 66 is used to expand the cross-sectional area of the bottom of the side wave dissipating assembly 25, so that it is easier to construct the wave dissipating assembly on the bottom foundation 5 later, and also reduces the local bearing stress of the bottom foundation 5. The second base 66 is preferably a solid plate or a box-shaped member, which can be integrally prefabricated with the side wave dissipating assembly 25.

[0354] The second base 66 is connected with the first base 65 and can be integrally prefabricated.

[0355] As shown in Fig. 38, in the secondary flow-through wave dissipating structure 2, the side wave dissipating assembly 25 is connected with the adjacent wave dissipating assembly 8, and specifically, the secondary connecting member 23 is connected between the side wave dissipating assembly 25 and the wave dissipating assembly 8. The secondary connecting member 23 can only serve as a connecting member between the side wave dissipating assembly 25 and the wave dissipating assembly 8, or can also simultaneously serve as a wave blocking member.

[0356] In a preferred manner, the secondary connecting member 23 is connected with the primary flow-through wave dissipating structure 1. The secondary connecting member 23 connects the primary flow-through wave dissipating structure 1 and the secondary flow-through wave dissipating structure 2 into a whole, forming a whole synergistic stress mechanism.

[0357] The secondary connecting member 23 can be a beam structure, or can be at least one of the following preferred schemes:

[0358] In the second-level flow-permeable wave-dissipation structure 2, the second-level connecting member 23 is connected between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8. The second-level connecting member 23 is located on the top of the second-level flow-permeable wave-dissipation structure 2, and the upper part of the second-level connecting member 23 protrudes upward from the second-level flow-permeable wave-dissipation structure 2. The second-level connecting member 23 can be used only as a connecting member between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8, or a second-level connecting member 23 can be provided as a wave-blocking plate above the high water level to further reduce waves while not affecting the water flow exchange in daily operation in non-extreme weather conditions, and can also serve as a connecting member between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8, thereby enhancing the stability of the side wave-dissipation assembly 25 and the wave-dissipation assembly 8.

[0359] As shown in FIG. 19, in a second preferred embodiment, the second-level connecting member 23 includes a second-level wave-blocking wall two 22. In the second-level flow-permeable wave-dissipation structure 2, the second-level wave-blocking wall two 22 is connected between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8. The top of the second-level wave-blocking wall two 22 is flush with the top of the wave-dissipation assembly 8 or is lower than the top of the wave-dissipation assembly 8, and the second-level wave-blocking wall two 22 is located above the second-level port 27. The second-level wave-blocking wall two 22 serves as a wave-blocking function near the sea surface in daily operation in non-extreme weather conditions, further enhances the wave-blocking effect, and has little effect on the water flow through the second-level port 27, while also serving as a connecting member between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8, thereby enhancing the structural stability on both sides of the second-level port 27.

[0360] Specifically, in the second-level flow-permeable wave-dissipation structure 2, the second-level wave-blocking wall two 22 is connected between the inclined wave-blocking wall 26 and the adjacent side wave-blocking wall 12.

[0361] The second-level wave-blocking wall two 22 can be a plate member or a box girder member.

[0362] As shown in FIG. 15, in a third preferred embodiment, the second-level flow-permeable wave-dissipation structure 2 includes a connecting structure two 62 connected between the side wave-dissipation assembly 25 and the adjacent wave-dissipation assembly 8. The connecting structure two 62 is located at the bottom of the second-level port 27.

[0363] The connecting structure two 62 can serve as a connecting member between the wave-dissipation assembly 8 on one side and the side wave-dissipation assembly 25 on the other side, thereby enhancing the structural stability on both sides of the second-level port 27, and can also serve as a surrounding structure when filling with rubble or other structures at the lower part of the second-level flow-permeable wave-dissipation structure 2.

[0364] The connecting structure two 62 is preferably a plate structure or a frame-outer-covering-panel combined structure.

[0365] As shown in Fig. 16, the main flow guide wall 11 of the wave dissipating assembly 8 of the secondary wave dissipating structure 2 is arranged corresponding to the primary wave gate 17, and the main flow guide wall 11 is arranged spaced apart from the side flow guide wall 12 of the adjacent primary wave dissipating structure 1.

[0366] The secondary wave dissipating structure 2 is higher than the primary wave dissipating structure 1.

[0367] As shown in Fig. 16, in a preferred mode of the secondary wave dissipating structure 2, the wave dissipating assembly 8 of the primary wave dissipating structure 1 and the wave dissipating assembly 8 of the secondary wave dissipating structure 2 are arranged in the same direction.

[0368] As shown in Fig. 20, in a preferred mode, the distance from the outer end of the main flow guide wall 11 of the secondary wave dissipating structure 2 to the primary wave gate 17 is T1, and 0≤T1≤2C1, wherein C1 is the width of the primary wave gate 17. This enables the main flow guide wall 11 of the secondary wave dissipating structure 2 to better achieve the purpose of flow splitting.

[0369] As shown in Fig. 21, in another preferred mode, the main flow guide wall 11 of the secondary wave dissipating structure 2 penetrates the primary wave gate 17.

[0370] As shown in Fig. 16, the side wave dissipating assembly 25 of the secondary wave dissipating structure 2, the wave dissipating assembly 8 of the adjacent secondary wave dissipating structure 2, and the wave dissipating assembly 8 of the adjacent primary wave dissipating structure 1 enclose a secondary energy dissipation area 21, which is connected to a primary wave gate 17 and a secondary wave gate 27 located on the side of the secondary energy dissipation area 21 away from the primary wave dissipating structure 1.

[0371] When the water flow or wave passes through the primary wave gate 17, the main flow guide wall 11 of the wave dissipating assembly 8 of the secondary wave dissipating structure 2 splits the flow near the primary wave gate 17, and a part of the water flow or wave enters the secondary energy dissipation area 21 through the gap between the main flow guide wall 11 and the adjacent side flow guide wall 12 of the primary wave dissipating structure 1. Then, a part of the water flow or wave that enters the secondary energy dissipation area 21 changes direction at the junction of the main flow guide wall 11 and the side flow guide wall 12 and flows to the secondary wave gate 27 after traveling a certain distance along the main flow guide wall 11. This part of the water flow or wave has a relatively high speed, while the water flow or wave at the middle of the secondary energy dissipation area 21 has a very slow speed. The high-speed water flow or wave will drive the water flow or wave at the middle of the tank to rotate, causing strong vortexes and water flow turbulence in the secondary energy dissipation area 21. Thus, the secondary energy dissipation area 21 becomes an energy dissipation pool, and the wave dissipates energy in the secondary energy dissipation area 21, thereby achieving the purpose of reducing wave height.

[0372] As shown in Fig. 16, in a preferred manner, the side side wave dissipating assembly 25 is formed with a side side gate one 20 between the adjacent wave dissipating assembly 8 of the primary flow-through wave dissipating structure 1, and the side side gate one 20 is communicated with the adjacent secondary energy dissipation area 21. Through the side side gate one 20, part of the water flow or wave moves along the side side wave dissipating assembly 25 to the inner wall of the secondary energy dissipation area 21 and flows to the secondary gate 27, and the water flow or wave at this part has a high speed, while the water flow or wave at the middle part of the secondary energy dissipation area 21 has a low speed. The high-speed water flow or wave drives the water flow or wave at the middle part of the tank to rotate, so that strong vortex and water flow turbulence are formed in the secondary energy dissipation area 21, thereby making the secondary energy dissipation area 21 become an energy dissipation pool, and the wave dissipates energy in the secondary energy dissipation area 21, thereby achieving the purpose of reducing the wave height. When the water flow of the primary gate 17 and the side side gate one 20 all enters the secondary energy dissipation area 21, at least two strong vortexes and water flow turbulences are formed in the secondary energy dissipation area 21 with a high probability, thereby making the energy dissipation effect of the secondary energy dissipation area 21 better, and thereby making the wave dissipating effect of the flow-through wave dissipating dam structure unit of the present application better.

[0373] As shown in Fig. 17, in another preferred manner of the secondary flow-through wave dissipating structure 2, the wave dissipating assembly 8 of the secondary flow-through wave dissipating structure 2 is arranged corresponding to the primary gate 17, the wave dissipating assembly 8 of the primary flow-through wave dissipating structure 1 and the wave dissipating assembly 8 of the secondary flow-through wave dissipating structure 2 are arranged reversely, and the included angle opening 18 formed by the two side flow guide walls 12 of the wave dissipating assembly 8 of the secondary flow-through wave dissipating structure 2 faces the primary gate 17.

[0374] The wave dissipating assembly 8 of the primary flow-through wave dissipating structure 1 is arranged corresponding to the secondary gate 27, and the included angle opening 18 formed by the two side flow guide walls 12 of the wave dissipating assembly 8 of the primary flow-through wave dissipating structure 1 faces the secondary gate 27.

[0375] As shown in Fig. 22, when the wave dissipating assembly of the primary flow-through wave dissipating structure and the wave dissipating assembly of the secondary flow-through wave dissipating structure are arranged reversely, the water level difference causes a pressure difference, and the arrow at the lower part of Fig. 22 represents the pressure difference caused by the water level difference. As shown in Fig. 22, the above scheme makes the channel between the primary gate 17 and the secondary gate 27 have a shape similar to “N”, and through the “N”-shaped channel, the wave propagation path is increased and the tortuosity is increased, thereby achieving the purposes of dissipating wave energy and reducing wave height.

[0376] At the same time, through the "N" type channel, it is difficult for waves to pass through easily, and part of the waves or exist reflection, which forms a higher water column in the channel between the first flow-through wave dissipation structure 1 and the second flow-through wave dissipation structure 2, not only enhances the energy dissipation effect of the waves in the "N" type channel, but also increases the pressure of the water flow on the lower foundation 5, and at the same time, the above-mentioned waves or water flow generates a larger reverse wave pressure to offset part of the positive wave pressure of the first flow-through wave dissipation structure 1 on the side away from the second flow-through wave dissipation structure 2.

[0377] And the flow-through wave dissipation dam structure unit described in the above-mentioned scheme is used to shield the structure as a large-scale marine ranching wave dissipation dam, when the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the flow-through wave dissipation dam structure unit from the rear end of the flow-through wave dissipation dam structure unit located at the far end, based on the same energy dissipation mechanism, the flow-through wave dissipation dam structure unit can better reduce wave reflection, greatly reducing or avoiding the probability of wave resonance in the ranching.

[0378] The above-mentioned form of the flow-through wave dissipation dam structure unit described in the present application can meet the purpose of flow-through wave dissipation in the water depth of 80m or less marine environment, and the first flow-through wave dissipation structure 1 has a wave dissipation assembly 8 corresponding to the second level gate 27 to avoid the wave directly impacting the second level gate 27, which may cause the flow-through wave dissipation dam structure unit described in the present application to not meet the wave dissipation condition.

[0379] Based on the above, compared with the existing wave dissipation dam with a cylinder from top to bottom and the existing caisson type vertical dam, the flow-through wave dissipation dam structure unit described in the present application effectively reduces the cost. Moreover, the number of adjustable structure parameters for different sea conditions is much larger than that of the existing wave dissipation dam with a cylinder from top to bottom, so that it can better meet the special needs under different working conditions, and has better cost performance under corresponding working conditions.

[0380] The flow-through wave dissipation dam structure unit described in the present embodiment is mainly suitable for the most unfavorable working condition of 100-year return period on the sea

wave height 16.5m, period 13.5s

[0381] The flow-through wave dissipation dam structure unit described in the present application has a light structure, and compared with the traditional vertical dam which is generally a caisson, the structure above the foundation 5 of the flow-through wave dissipation dam structure unit described in the present embodiment mainly has several wall bodies, which has a higher cost performance and a more sustainable development scheme.

[0382] The end of the second flow-through wave dissipation structure 2 protrudes from the first flow-through wave dissipation structure 1.

[0383] The first flow-through wave dissipation structure 1 and the second flow-through wave dissipation structure 2 are connected.

[0384] The first transverse beam is connected between the first transverse flow dissipating structure 1 and the second transverse flow dissipating structure 2, and part of the first transverse beam is connected to the upper part of the second transverse flow dissipating structure 2.

[0385] Since most of the wave force will impact the upper part of the first transverse flow dissipating structure 1, part of the first transverse beam is connected to the upper part of the second transverse flow dissipating structure 2, so that the first transverse flow dissipating structure 1 and the second transverse flow dissipating structure 2 can be stressed cooperatively, thereby effectively reducing the stress requirement of the first transverse flow dissipating structure 1.

[0386] The first transverse flow dissipating structure 1 or the second transverse flow dissipating structure 2 is integrally formed. For example, it is integrally poured and formed by reinforced concrete, so as to facilitate installation.

[0387] The first transverse flow dissipating structure 1 and the second transverse flow dissipating structure 2 are integrally formed. For example, it is integrally poured and formed by reinforced concrete, so as to facilitate installation.

[0388] The end of the second transverse flow dissipating structure 2 protrudes from the first transverse flow dissipating structure 1.

[0389] The distance from the outer end of the main flow guide wall 11 of the second transverse flow dissipating structure 2 to the first opening 17 is T1, and preferably: 0≤T1≤H s a 1％ / 3, wherein H s a 1％ is the design return period of 1% of the large wave height of a year.

[0390] Embodiment 4

[0391] As shown in FIGS. 1-47, the application also discloses a transverse flow dissipating dam structure unit, which is different from embodiment 3 in that the first transverse flow dissipating structure 1 and the second transverse flow dissipating structure 2 are alternately arranged in the direction from the first transverse flow dissipating structure 1 to the second transverse flow dissipating structure 2, forming 2-6 transverse flow dissipating structures.

[0392] The wave dissipating assembly 8 in at least part of the second transverse flow dissipating structure 2 is arranged in the same direction as the wave dissipating assembly 8 in at least one side adjacent first transverse flow dissipating structure 1; or, the wave dissipating assembly 8 in at least part of the second transverse flow dissipating structure 2 is arranged in the opposite direction of the wave dissipating assembly 8 in at least one side adjacent first transverse flow dissipating structure 1.

[0393] Embodiment 5

[0394] As shown in FIGS. 1-47, the application also discloses a flow-through wave dissipation dam construction unit, which is different from the embodiments 3 or 4 in that: in the direction from the secondary flow-through wave dissipation structure 2 to the primary flow-through wave dissipation structure 1, the secondary flow-through wave dissipation structure 2 and the primary flow-through wave dissipation structure 1 are arranged alternately to form a 2-6 level flow-through wave dissipation structure.

[0395] The wave dissipation components 8 in at least part of the secondary flow-through wave dissipation structure 2 are arranged in the same direction as the wave dissipation components 8 in at least one side adjacent primary flow-through wave dissipation structure 1; or, the wave dissipation components 8 in at least part of the secondary flow-through wave dissipation structure 2 are arranged in the opposite direction of the wave dissipation components 8 in at least one side adjacent primary flow-through wave dissipation structure 1.

[0396] Embodiment 6

[0397] As shown in FIGS. 32, 33, 35 and 37, the application also discloses a flow-through wave dissipation dam construction unit, which is different from the embodiments 3 or 4 or 5 in that: the secondary flow-through wave dissipation structure 2 is provided with a tertiary flow-through wave dissipation structure 3 away from one side of the primary flow-through wave dissipation structure 1, the tertiary flow-through wave dissipation structure 3 is provided with a tertiary port gate 31 through it, and the tertiary port gate 31 is arranged staggered with and communicated with the secondary port gate 27. The wave is blocked by the primary flow-through wave dissipation structure 1, the secondary flow-through wave dissipation structure 2 and the tertiary flow-through wave dissipation structure 3, and the water flow exchange on both sides of the flow-through wave dissipation dam construction unit is realized by the primary port gate 17, the secondary port gate 27 and the tertiary port gate 31 which are communicated with each other. The primary port gate 17 and the secondary port gate 27 are arranged staggered, and the secondary port gate 27 is arranged staggered with the secondary port gate 27, so that the water flow exchange on both sides of the flow-through wave dissipation dam construction unit can be realized, and the flow-through wave dissipation dam construction unit can effectively weaken the wave.

[0398] The tertiary port gate 31 is arranged staggered with the secondary port gate 27, that is, in the direction from the secondary flow-through wave dissipation structure 2 to the tertiary flow-through wave dissipation structure 3, the projection of the secondary port gate 27 on the tertiary flow-through wave dissipation structure 3 has no intersection with the tertiary port gate 31. In this way, the wave dissipation effect of the water flow through the secondary flow-through wave dissipation structure 2 and the tertiary flow-through wave dissipation structure 3 can be better.

[0399] The tertiary flow-through wave dissipation structure 3 also includes at least one wave dissipation component 8 as described in the application, the wave dissipation component 8 of the tertiary flow-through wave dissipation structure 3 is arranged corresponding to the secondary port gate 27, and at least one side of the tertiary port gate 31 is provided with a wave dissipation component 8.

[0400] The tertiary flow-through wave dissipation structure 3 is higher than the secondary flow-through wave dissipation structure 2.

[0401] The third flow-through wave dissipating structure 3 comprises at least two wave dissipating assemblies 8, wherein a third port 31 is formed between adjacent wave dissipating assemblies 8, and the adjacent wave dissipating assemblies 8 are arranged in the same direction.

[0402] As shown in FIGS. 35b and 35c, one arrangement of the third flow-through wave dissipating structure 3 is that the wave dissipating assemblies 8 of the third flow-through wave dissipating structure 3 and the wave dissipating assemblies 8 of the second flow-through wave dissipating structure 2 are arranged in the same direction.

[0403] As shown in FIG. 35b, the main flow guide wall 11 of the third flow-through wave dissipating structure 3 points to the second port 27, and the adjacent wave dissipating assemblies 8 of the third flow-through wave dissipating structure 3 and the wave dissipating assemblies 8 of the second flow-through wave dissipating structure 2 enclose a third energy dissipation area 30, and the third energy dissipation area 30 is connected with the second port 27 and the third port 31 located on the side of the third energy dissipation area 30 away from the second flow-through wave dissipating structure 2.

[0404] When the water flow or wave passes through the second port 27, the water flow or wave is divided by the main flow guide wall 11 of the wave dissipating assembly 8 of the third flow-through wave dissipating structure 3 near the second port 27, and a part of the water flow or wave enters the third energy dissipation area 30 through the gap between the main flow guide wall 11 and the adjacent side flow guide wall 12 of the second flow-through wave dissipating structure 2, and then the water flow or wave entering the third energy dissipation area 30 changes direction at the junction of the main flow guide wall 11 and the side flow guide wall 12 and flows to the third port 31. The water flow or wave has a high speed, while the water flow or wave at the middle part of the third energy dissipation area 30 has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle part of the third energy dissipation area 30 to rotate, so that strong vortex and water flow turbulence are formed in the third energy dissipation area 30, thereby making the third energy dissipation area 30 become an energy dissipation pool, and the wave dissipates energy in the third energy dissipation area 30, thereby achieving the purpose of reducing the wave height.

[0405] As shown in FIG. 23, the distance from the outer end of the main flow guide wall 11 of the third flow-through wave dissipating structure 3 to the second port 27 is T2, and 0≤T2≤2C2, wherein C2 is the width of the second port 27. This makes the main flow guide wall 11 of the third flow-through wave dissipating structure 3 have a better flow dividing purpose.

[0406] In a preferred manner, the main flow guide wall 11 of the third flow-through wave dissipating structure 3 penetrates the second port 27.

[0407] As shown in Fig. 35c, in a preferred mode, the main flow guide wall 11 of the secondary wave dissipation structure 2 points to the tertiary port 31, the side wave dissipation component 25 of the secondary wave dissipation structure 2, the adjacent wave dissipation component 8 in the secondary wave dissipation structure 2, and the adjacent wave dissipation component 8 in the adjacent tertiary wave dissipation structure 3 form a tertiary energy dissipation area 30, which is connected to the secondary port 27 and the tertiary port 31.

[0408] After the water flow or wave passes through the secondary port 27 and enters the tertiary energy dissipation area 30, part of the water flow or wave flows along the side flow guide wall 12 on one side for a distance and then changes direction at the junction of the side flow guide wall 12 and the main flow guide wall 11, flowing to the tertiary port 31. The water flow or wave at this point has a high speed, while the water flow or wave at the middle of the tertiary energy dissipation area 30 has a very slow speed. The high-speed water flow or wave will drive the water flow or wave at the middle of the tertiary energy dissipation area 30 to rotate, causing strong vortexes and water flow turbulence in the tertiary energy dissipation area 30, thereby making the tertiary energy dissipation area 30 an energy dissipation pool. The wave dissipates energy in the tertiary energy dissipation area 30, thereby achieving the purpose of reducing wave height.

[0409] In a preferred mode, the side port two 32 is formed between the side wave dissipation component 25 and the adjacent wave dissipation component 8 on the tertiary wave dissipation structure 3, and the side port two 32 is connected to the adjacent tertiary energy dissipation area 30. After the water flow or wave passes through the secondary port 27 and enters the tertiary energy dissipation area 30, part of the water flow or wave flows along the side wave dissipation component 25 on one side for a distance and then flows to the side port two 32. The water flow or wave at this point has a high speed, while the water flow or wave at the middle of the tertiary energy dissipation area 30 has a very slow speed. The high-speed water flow or wave will drive the water flow or wave at the middle of the tertiary energy dissipation area 30 to rotate, causing strong vortexes and water flow turbulence in the tertiary energy dissipation area 30, thereby making the tertiary energy dissipation area 30 an energy dissipation pool. The wave dissipates energy in the tertiary energy dissipation area 30, thereby achieving the purpose of reducing wave height.

[0410] Moreover, after the water flow or wave passes through the secondary port 27 and enters the tertiary energy dissipation area 30, part of the water flow or wave flows along the wave dissipation component 8 on one side to the tertiary port 31, and part of the water flow or wave flows along the side wave dissipation component 25 on the other side for a distance and then flows to the side port two 32. With high probability, at least two strong vortexes and water flow turbulence will be formed in the secondary energy dissipation area 21, thereby making the energy dissipation effect of the tertiary energy dissipation area 30 better, and thereby making the wave dissipation effect of the wave dissipation dam structure unit of the present application better.

[0411] As shown in Fig. 33, further, the inclined flow guide wall 26 or normal flow guide wall 28 on the secondary wave dissipating structure 2 is connected with the adjacent side flow guide wall 12 on the tertiary wave dissipating structure 3, and the secondary wave dissipating wall 24 is located above the side port gate 32.

[0412] The tertiary wave dissipating wall 33 can play a role of wave blocking near the sea surface, further enhance the wave blocking effect, and has little influence on the water flow through the side port gate 20, and can also play a connecting role between the side wave dissipating assembly 25 and the adjacent side flow guide wall 12 on the tertiary wave dissipating structure 3, and enhance the structural stability on both sides of the side port gate 20.

[0413] As shown in Figs. 35a and 35d, another setting form of the tertiary wave dissipating structure 3 is that the wave dissipating assembly 8 of the tertiary wave dissipating structure 3 and the wave dissipating assembly 8 of the secondary wave dissipating structure 2 are reversely arranged.

[0414] As shown in Fig. 35a, in a specific preferred mode, the included angle opening 18 formed by the two side flow guide walls 12 of the wave dissipating assembly 8 of the tertiary wave dissipating structure 3 faces the secondary port gate 27.

[0415] As shown in Fig. 35a, further preferably, the wave dissipating assembly 8 of the secondary wave dissipating structure 2 is arranged corresponding to the tertiary port gate 31, and the included angle opening 18 formed by the two side flow guide walls 12 of the wave dissipating assembly 8 of the secondary wave dissipating structure 2 faces the tertiary port gate 31.

[0416] The above scheme makes the passage between the secondary port gate 27 and the tertiary port gate 31 into a similar "N" type, and through the "N" type passage, the wave propagation path and tortuosity are increased, so as to consume wave energy and reduce wave height.

[0417] At the same time, through the "N" type passage, it is difficult for the wave to pass through, and part of the wave or exists reflection, which forms a water column with high water level in the passage between the tertiary wave dissipating structure 3 and the secondary wave dissipating structure 2, not only enhances the energy consumption effect of the wave in the "N" type passage, but also increases the pressure of the water flow on the lower foundation 5, and at the same time, the above wave or water flow generates a large reverse wave pressure to offset part of the positive wave pressure of the wave or water flow on the side of the secondary wave dissipating structure 2 away from the tertiary wave dissipating structure 3 on the secondary wave dissipating structure 2.

[0418] And when the above-mentioned wave dissipation dam structure unit is used to shield the structure as a large-scale marine ranching wave dissipation dam, the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the above-mentioned wave dissipation dam structure unit from the rear end of the above-mentioned wave dissipation dam structure unit located at the far end, based on the same energy dissipation mechanism, the wave dissipation dam structure unit can better reduce wave reflection, greatly reducing or avoiding the probability of wave resonance in the ranching.

[0419] As shown in FIG. 35d, another specific preferred mode, the wave dissipation assembly 8 of the secondary wave dissipation structure 2 is arranged corresponding to the tertiary port door 31, and the main flow guide wall body 11 of the wave dissipation assembly 8 of the secondary wave dissipation structure 2 faces the tertiary port door 31.

[0420] In the tertiary wave dissipation structure 3, a tertiary connecting piece 34 is connected between adjacent wave dissipation assemblies 8. The tertiary connecting piece 34 can only serve as a connecting piece between the side wave dissipation assembly 25 and the wave dissipation assembly 8, or can also serve as a wave blocking function.

[0421] A preferred mode is that the tertiary connecting piece 34 is connected with the secondary wave dissipation structure 2. The tertiary connecting piece 34 connects the tertiary wave dissipation structure 3 and the secondary wave dissipation structure 2 into a whole, forming a whole cooperative stress mechanism.

[0422] The secondary connecting piece 23 can be a beam structure, or at least one of the following preferred modes:

[0423] A preferred mode is that the tertiary connecting piece 34 includes a third parapet 36, the third parapet 36 is located at the top of the tertiary wave dissipation structure 3, and the upper part of the third parapet 36 protrudes upward from the tertiary wave dissipation structure 3. The third parapet 36 can only serve as a connecting piece between adjacent wave dissipation assemblies 8 in the tertiary wave dissipation structure 3. When the third parapet 36 is arranged as a wave blocking plate above the high water level, it further reduces the wave but does not affect the flow exchange in daily operation under non-extreme weather conditions, and can also serve as a connecting function between adjacent wave dissipation assemblies 8 in the tertiary wave dissipation structure 3, enhancing the stability of adjacent wave dissipation assemblies 8 in the tertiary wave dissipation structure 3.

[0424] A more preferred mode is that the top height of the third parapet 36 is higher than the top height of the second parapet 29.

[0425] As shown in Fig. 33, the third connecting member 34 includes a third wave barrier 35, and the third wave dissipating structure 3 is connected between the side walls 12 of adjacent wave dissipating assemblies 8. The top of the third wave barrier 35 is flush with the top of the wave dissipating assembly 8 or lower than the top of the wave dissipating assembly 8, and the third wave barrier 35 is located above the third port 31. The third wave barrier 35 can play a role of a wave barrier near the sea surface in daily operation under non-extreme weather conditions, further enhance the wave barrier effect, and has little effect on the water flow through the third port 31. At the same time, the third wave barrier 35 can also play a connecting role between adjacent wave dissipating assemblies 8, and enhance the structural stability of the two sides of the third port 31.

[0426] In a third preferred embodiment, the third wave dissipating structure 3 is connected between the side walls 12 of adjacent wave dissipating assemblies 8 by a connecting structure 63, and the connecting structure 63 is located at the bottom of the third port 31.

[0427] The connecting structure 63 is preferably a plate structure or a frame with an outer covering panel structure. The connecting structure 63 can play a connecting role between the two wave dissipating assemblies 8, enhance the stability of the wave dissipating assemblies 8 on both sides of the third port 31, and serve as a barrier when filling with rubble or other structures at the lower part of the third wave dissipating structure 3.

[0428] As shown in Fig. 35, the third wave dissipating structure 3 includes at least two wave dissipating assemblies 8, and the wave dissipating assemblies 8 are arranged in the same direction.

[0429] As shown in Figs. 35b and 35c, the wave dissipating assemblies 8 of the third wave dissipating structure 3 and the wave dissipating assemblies 8 of the second wave dissipating structure 2 are arranged in the same direction.

[0430] As shown in Fig. 23, the distance between the outer end of the main flow guide wall 11 of the third wave dissipating structure 3 and the second port 27 is T2, and 0≤T2≤H s a 1％ / 3, where H s a 1％ a is the design return period of 1% of the annual maximum wave height.

[0431] As shown in the figure, the main flow guide wall 11 of the third wave dissipating structure 3 penetrates the second port 27.

[0432] As shown in Figs. 35a and 35d, the wave dissipating assemblies 8 of the third wave dissipating structure 3 and the wave dissipating assemblies 8 of the second wave dissipating structure 2 are arranged in opposite directions.

[0433] As shown in FIG. 35a, the two side flow guide walls 12 of the wave dissipation assembly 8 of the third-level wave dissipation structure 3 form an included angle opening 18 towards the second-level port gate 27.

[0434] The third-level wave dissipation structure 3 is connected with the second-level wave dissipation structure 2.

[0435] The second cross beam is connected between the third-level wave dissipation structure 3 and the second-level wave dissipation structure 2.

[0436] The first cross beam is connected between the first-level wave dissipation structure 1 and the second-level wave dissipation structure 2, and the second cross beam is correspondingly arranged with the first cross beam.

[0437] The third-level wave dissipation structure 3 or the second-level wave dissipation structure 2 is integrally formed. For example, it is integrally poured and formed by reinforced concrete to facilitate installation.

[0438] The third-level wave dissipation structure 3 and the second-level wave dissipation structure 2 are integrally formed. For example, it is integrally poured and formed by reinforced concrete to facilitate installation.

[0439] The third-level wave dissipation structure 3 is higher than the second-level wave dissipation structure 2.

[0440] FIGS. 43 and 44 are schematic diagrams of water flow through a wave dissipation dam structure unit according to the present application. It is worth noting that the water flow is three-dimensional and has many influencing factors, so FIGS. 43 and 44 show the general direction of the water flow.

[0441] Embodiment 7

[0442] As shown in FIGS. 36, 38, 39 and 48, the wave dissipation dam structure unit according to the present embodiment is different from that of embodiment 6 in that the third-level wave dissipation structure 3 is further provided with a fourth-level wave dissipation structure 4 away from one side of the second-level wave dissipation structure 2, wherein the fourth-level wave dissipation structure 4 is provided with a fourth-level port gate 41 therethrough, and the fourth-level port gate 41 and the third-level port gate 31 are connected and arranged staggered.

[0443] The fourth-level wave dissipation structure 4 is a coping strategy of the wave dissipation dam structure unit according to the present embodiment for larger water depth and longer period waves. When the energy dissipation pool

damping pool

[0444] The wave blocking is performed by the first wave penetration and dissipation structure 1, the second wave penetration and dissipation structure 2, the third wave penetration and dissipation structure 3 and the fourth wave penetration and dissipation structure 4, and the water exchange on both sides of the wave penetration and dissipation dam structure unit is performed by the first port gate 17, the second port gate 27, the third port gate 31 and the fourth port gate 41 which are connected. The first port gate 17 and the second port gate 27 are staggered, the second port gate 27 and the second port gate 27 are staggered, and the fourth port gate 41 and the third port gate 31 are staggered, so that the water exchange on both sides of the wave penetration and dissipation dam structure unit can be performed, and the wave penetration and dissipation dam structure unit can effectively weaken the wave.

[0445] The fourth port gate 41 and the third port gate 31 are staggered, that is, the projection of the third port gate 31 to the fourth wave penetration and dissipation structure 4 has no intersection with the fourth port gate 41 in the direction from the third wave penetration and dissipation structure 3 to the fourth wave penetration and dissipation structure 4. In this way, the wave dissipation effect of the water flowing through the third wave penetration and dissipation structure 3 to the fourth wave penetration and dissipation structure 4 is better.

[0446] The fourth wave penetration and dissipation structure 4 also includes at least one wave dissipation assembly 8 as described in the present application; the wave dissipation assembly 8 of the fourth wave penetration and dissipation structure 4 is correspondingly arranged with the third port gate 31, and at least one side of the wave dissipation assembly 8 is provided with the fourth port gate 41.

[0447] The end of the fourth wave penetration and dissipation structure 4 protrudes from the third wave penetration and dissipation structure 3.

[0448] The third wave penetration and dissipation structure 3 and the fourth wave penetration and dissipation structure 4 are integrally formed. For example, they are integrally poured and formed by reinforced concrete, which is convenient for installation.

[0449] The third wave penetration and dissipation structure 3 and the fourth wave penetration and dissipation structure 4 are integrally formed. For example, they are integrally poured and formed by reinforced concrete, which is convenient for installation.

[0450] The fourth wave penetration and dissipation structure 4 also includes the side wave dissipation assembly 25, and the fourth wave penetration and dissipation structure 4 is formed with the fourth port gate 41 between the side wave dissipation assembly 25 and the wave dissipation assembly 8.

[0451] The side wave dissipation assembly 25 of the fourth wave penetration and dissipation structure 4 is arranged at both ends of the fourth wave penetration and dissipation structure 4.

[0452] As shown in FIG. 38, the fourth wave penetration and dissipation structure 4 is connected with the fourth connecting piece 43 between the side wave dissipation assembly 25 and the adjacent wave dissipation assembly 8. The fourth connecting piece 43 can only serve as a connecting piece between the side wave dissipation assembly 25 and the wave dissipation assembly 8, or can also serve as a wave blocking function.

[0453] A preferred scheme is that the fourth-level connecting member 43 is connected with the third-level wave-permeating and dissipating structure 3, the fourth-level wave-permeating and dissipating structure 4 and the third-level wave-permeating and dissipating structure 3 are connected as a whole by the fourth-level connecting member 43, and a whole force-receiving mechanism is formed.

[0454] The fourth-level connecting member 43 can be a beam structure or at least one of the following preferred schemes:

[0455] As shown in FIG. 39, in a preferred scheme one, the fourth-level connecting member 43 comprises a fourth parapet 48, the fourth parapet 48 is connected between the side wave-dissipating assembly 25 and the adjacent wave-dissipating assembly 8 in the fourth-level wave-permeating and dissipating structure 4, the fourth parapet 48 is located on the top of the wave-dissipating assembly 8, and the upper part of the fourth parapet 48 protrudes upwards from the fourth-level wave-permeating and dissipating structure 4.

[0456] The fourth parapet 48 can only serve as a connecting member between the side wave-dissipating assembly 25 and the adjacent wave-dissipating assembly 8, and the fourth parapet 48 is arranged as a wave-stopping plate above the high water level, which can further dissipate waves but does not affect the water flow exchange in daily operation under non-extreme weather conditions, plays a role in preventing overtopping under certain working conditions, and also serves as a connecting member between the side wave-dissipating assembly 25 and the adjacent wave-dissipating assembly 8, thereby enhancing the stability of the side wave-dissipating assembly 25 and the wave-dissipating assembly 8.

[0457] As shown in FIG. 48, in a preferred scheme two, the fourth-level connecting member 43 comprises a fourth-level wave-stopping wall one 44, the fourth-level wave-stopping wall one 44 is connected between the side wave-dissipating assembly 25 and the side flow guide wall 12 of the adjacent wave-dissipating assembly 8 in the fourth-level wave-permeating and dissipating structure 4, the top of the fourth-level wave-stopping wall one 44 is flush with the wave-dissipating assembly 8 or the top of the fourth-level wave-stopping wall one 44 is lower than the top of the wave-dissipating assembly 8, and the fourth-level wave-stopping wall one 44 is located above the fourth-level port gate 41.

[0458] The fourth-level wave-stopping wall one 44 plays a role in stopping waves near the sea surface under daily operation in non-extreme weather conditions, further enhances the wave-stopping effect, has little influence on the water flow passing through the fourth-level port gate 41, and also serves as a connecting member between the side wave-dissipating assembly 25 and the adjacent wave-dissipating assembly 8, thereby enhancing the structural stability of the fourth-level port gate 41.

[0459] The fourth-level wave-stopping wall one 44 plays a role in stopping waves near the sea surface under daily operation in non-extreme weather conditions, further enhances the wave-stopping effect, has little influence on the water flow passing through the fourth-level port gate 41, and also serves as a connecting member between the side wave-dissipating assembly 25 and the adjacent wave-dissipating assembly 8, thereby enhancing the structural stability of the fourth-level port gate 41.

[0460] Specifically, in the fourth-level wave-damping structure 4, the fourth-level wave-damping wall 44 is connected between the inclined wave guide wall 26 and the adjacent side wave guide wall 12.

[0461] The second-level wave-damping wall 22 can be a plate member or a box girder member.

[0462] In a third preferred embodiment, the fourth-level connecting member 43 comprises a fourth connecting structure 64, and in the fourth-level wave-damping structure 4, the side wave-damping assembly 25 and the adjacent wave-damping assembly 8 are connected by the fourth connecting structure 64, which is located at the bottom of the fourth-level port 41.

[0463] The fourth connecting structure 64 can serve as a connection between the side wave-damping assembly 25 and the adjacent wave-damping assembly 8, enhancing the stability of the wave-damping assemblies 8 on both sides of the fourth-level port 41, and can also serve as a barrier when filling structures such as gravel are needed at the lower part of the first-level wave-damping structure 1.

[0464] The fourth connecting structure 64 is preferably a plate member structure or a frame-outer-covering-panel combined structure.

[0465] As shown in FIGS. 36a, 36b, 36c, and 36d, in a preferred embodiment, the wave-damping assemblies 8 of the fourth-level wave-damping structure 4 and the wave-damping assemblies 8 of the third-level wave-damping structure 3 are arranged in the same direction.

[0466] As shown in FIGS. 36a and 36c, in a preferred embodiment of the fourth-level wave-damping structure 4, the wave-damping assemblies 8 of the fourth-level wave-damping structure 4 and the wave-damping assemblies 8 of the first-level wave-damping structure 1 are arranged in the same direction.

[0467] As shown in FIG. 25, in a preferred embodiment, the distance between the outer end of the main wave guide wall 11 of the fourth-level wave-damping structure 4 and the third-level port 31 is T3, and 0≤T3≤2C3, where C3 is the width of the third-level port 31. This allows the main wave guide wall 11 of the fourth-level wave-damping structure 4 to better serve as a flow divider.

[0468] As shown in FIG. 26, the main wave guide wall 11 of the fourth-level wave-damping structure 4 penetrates the third-level port 31.

[0469] As shown in FIGS. 36a, 36b, 36c, and 36d, the side wave-damping assembly 25 of the fourth-level wave-damping structure 4, the adjacent wave-damping assembly 8 in the fourth-level wave-damping structure 4, and the adjacent wave-damping assembly 8 in the third-level wave-damping structure 3 form a fourth-level energy dissipation area 40, which is connected to the third-level port 31 and the fourth-level port 41.

[0470] When the water flow or wave passes through the tertiary port gate 31, the water flow or wave is divided by the main flow guide wall 11 of the wave dissipation assembly 8 of the quaternary flow-through wave dissipation structure 4 near the tertiary port gate 31, and part of the water flow or wave enters the quaternary energy dissipation area 40 through the gap between the main flow guide wall 11 and the adjacent side flow guide wall 12 of the tertiary flow-through wave dissipation structure 3, and then part of the water flow or wave entering the quaternary energy dissipation area 40 changes direction through the intersection of the main flow guide wall 11 and the side flow guide wall 12 and flows to the quaternary port gate 41. The water flow or wave has a high speed, while the water flow or wave at the middle position of the quaternary energy dissipation area 40 has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the quaternary energy dissipation area 40 to rotate, so that strong vortexes and water flow turbulence are formed in the quaternary energy dissipation area 40, thereby making the quaternary energy dissipation area 40 become an energy dissipation pool. The wave dissipates energy in the quaternary energy dissipation area 40, thereby achieving the purpose of reducing the wave height.

[0471] The side wave dissipation assembly 25 and the adjacent wave dissipation assembly 8 of the tertiary flow-through wave dissipation structure 3 form a side tertiary port gate 42, which is in communication with the adjacent quaternary energy dissipation area 40.

[0472] Part of the water flow or wave passing through the side tertiary port gate 42 flows along the side wave dissipation assembly 25 close to the inner wall of the quaternary energy dissipation area 40 and flows to the quaternary port gate 41. The water flow or wave has a high speed, while the water flow or wave at the middle position of the quaternary energy dissipation area 40 has a very slow speed. The high-speed water flow or wave drives the water flow or wave at the middle position of the quaternary energy dissipation area 40 to rotate, so that strong vortexes and water flow turbulence are formed in the quaternary energy dissipation area 40, thereby making the quaternary energy dissipation area 40 become an energy dissipation pool. The wave dissipates energy in the quaternary energy dissipation area 40, thereby achieving the purpose of reducing the wave height.

[0473] When the water flow of the tertiary port gate 31 and the side tertiary port gate 42 all enters the quaternary energy dissipation area 40, at least two strong vortexes and water flow turbulence are formed in the quaternary energy dissipation area 40 with a high probability, thereby making the energy dissipation effect of the quaternary energy dissipation area 40 better, and thereby making the wave dissipation effect of the flow-through wave dissipation dam structure unit of the present application better.

[0474] In a preferred mode, the main flow guide wall 11 of the tertiary flow-through wave dissipation structure 3 points to the quaternary port gate 41.

[0475] The wave dissipation assembly 8 of the quaternary flow-through wave dissipation structure 4 and the adjacent wave dissipation assembly 8 of the tertiary flow-through wave dissipation structure 3 enclose the quaternary energy dissipation area 40, and the quaternary energy dissipation area 40 is in communication with the tertiary port gate 31 and at least two quaternary port gates 41.

[0476] After the water flow or wave passes through the third-level port gate 31 and enters the fourth-level energy consumption area 40, a part of the water flow or wave flows along the side guide wall 12 of the wave dissipation assembly 8 on one side for a distance and then changes direction at the intersection of the side guide wall 12 and the main guide wall 11 to flow to the fourth-level port gate 41 on the same side. The speed of this part of the water flow or wave is relatively fast, while the speed of the water flow or wave at the middle position in the fourth-level energy consumption area 40 is very slow. The high-speed water flow or wave will drive the water flow or wave at the middle position in the bin to rotate, so that strong vortexes and water flow turbulence are formed in the fourth-level energy consumption area 40. Therefore, the fourth-level energy consumption area 40 becomes an energy consumption pool, and the wave consumes energy in the fourth-level energy consumption area 40, thereby achieving the purpose of reducing the wave height.

[0477] At the same time, a part of the water flow or wave flows along the side guide wall 12 of the wave dissipation assembly 8 on the other side for a distance and then changes direction at the intersection of the side guide wall 12 and the main guide wall 11 to flow to the fourth-level port gate 41 on the same side. The speed of this part of the water flow or wave is relatively fast, while the speed of the water flow or wave at the middle position in the fourth-level energy consumption area 40 is very slow. The high-speed water flow or wave will drive the water flow or wave at the middle position in the bin to rotate, so that strong vortexes and water flow turbulence are formed in the fourth-level energy consumption area 40. Therefore, the fourth-level energy consumption area 40 becomes an energy consumption pool, and the wave consumes energy in the fourth-level energy consumption area 40, thereby achieving the purpose of reducing the wave height.

[0478] In summary, after the water flow or wave passes through the third-level port gate 31 and enters the fourth-level energy consumption area 40, it will most likely form at least two strong vortexes and water flow turbulence in the fourth-level energy consumption area 40 during the process of reaching at least two fourth-level port gates 41. Therefore, the energy consumption effect of the fourth-level energy consumption area 40 is better, and the wave dissipation effect of the flow-through wave dissipation dam structure unit of the present application is better.

[0482] [According to the rules 91 correction 10.07.2025] The above scheme makes the passage from the three-level port door 31 to the four-level port door 41 into a similar "N" type, through the "N" type passage, the growth of the wave propagation path and the tortuosity, so as to consume wave energy and reduce wave height.

[0483] [According to the rules 91 correction 10.07.2025] At the same time, through the "N" type passage, it is difficult for the wave to pass through, and part of the wave or exists reflection, which forms a water column with a higher water level in the passage between the three-level flow-through wave dissipation structure 3 and the four-level flow-through wave dissipation structure 4, not only enhances the energy consumption effect of the wave in the "N" type passage, but also increases the pressure of the water flow on the lower foundation 5, and at the same time, the above wave or water flow generates a larger reverse wave pressure to offset part of the positive wave pressure of the three-level flow-through wave dissipation structure 3 on the side away from the four-level flow-through wave dissipation structure 4.

[0484] [According to the rules 91 correction 10.07.2025] Moreover, when the flow-through wave dissipation dam structure unit described in the above scheme is used to shield the structure as a large-scale marine ranching wave dissipation dam, after the wind-generated waves inside the marine ranching and the external transmitted waves are transmitted to the far end, and then enter the flow-through wave dissipation dam structure unit from the rear end of the flow-through wave dissipation dam structure unit located at the far end, based on the same energy consumption mechanism, the flow-through wave dissipation dam structure unit can better reduce wave reflection and greatly reduce or avoid the probability of wave resonance in the ranching.

[0485] [According to the rules 91 correction 10.07.2025] The above form of the flow-through wave dissipation dam structure unit described in the present application can meet the flow-through wave dissipation purpose in the marine environment with a water depth of 80m or less, and at the same time, the three-level flow-through wave dissipation structure 3 has a wave dissipation assembly 8 corresponding to the four-level port door 41, so as to avoid the situation that the flow-through wave dissipation dam structure unit described in the present application does not meet the wave dissipation.

[0486] [According to the rules 91 correction 10.07.2025] On the basis of the above, compared with the existing wave dissipation dam with a cylinder from top to bottom and the existing sunk box type vertical dam, the flow-through wave dissipation dam structure unit described in the present application can effectively reduce the cost. Moreover, the number of adjustable structure parameters for different sea conditions is much larger than that of the existing wave dissipation dam with a cylinder from top to bottom, so as to better meet the special needs in different working conditions and make it have better cost performance in the corresponding working conditions.

[0487] The flow-through wave dissipation dam structure unit described in the present embodiment is mainly suitable for the most unfavorable working condition of 100-year return period on the sea

[0493] The side wave dissipation component 25 of the fourth flow-through wave dissipation structure 4 is arranged at both ends of the second flow-through wave dissipation structure 2.
