Description

Technical Field

[0001] This utility model relates to the field of ecological protection, and in particular to a multi-layered wave-damping structure based on mangrove roots and aquaculture ponds. Background Technology

[0002] Traditional coastal protection projects lack consideration for ecological and environmental protection, and most of them use concrete components or riprap construction. While meeting the needs of disaster prevention and mitigation, they cause varying degrees of damage to the coastal ecological environment.

[0003] A search revealed that the Chinese announcement number is CN202122918190.3, which specifically describes an ecological transformation structure for hollow corner blocks. This structure comprises several hollow corner blocks arranged in an array. An environmentally friendly plant growing bag is placed in the hollow center of each hollow corner block, and plants are placed inside the growing bag. Several geogrids are laid longitudinally and transversely on the hollow corner blocks. This utility model provides an ecological transformation structure for hollow corner blocks for construction and modification.

[0004] The aforementioned patent mentions that "this utility model is modified and formed based on the existing four-legged hollow block slope protection, which does not require disassembly and reassembly, greatly reducing construction costs. Moreover, the built-in environmentally friendly plant bags and the longitudinally and transversely laid geogrids provide a good living and development space for salt-tolerant climbing plants, which is conducive to realizing the ecologicalization of the four-legged hollow block slope protection and improving the wave-dissipating function of the four-legged hollow block slope protection." However, in the existing technology, concrete breakwaters block the ecological cycle and destroy the natural habitat of mangroves. Single aquaculture ponds lack wave-dissipating capacity and are easily impacted by storm surges, causing aquaculture organisms to escape. Existing plant submerged dike structures only achieve physical wave dissipation and do not form a material cycle with the aquaculture system. Therefore, a multi-layer wave-dissipating structure based on mangrove roots and aquaculture ponds is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layered wave-damping structure based on mangrove roots and aquaculture ponds. It aims to improve the existing technologies where concrete breakwaters obstruct ecological cycles, damage the natural habitat of mangroves, and single aquaculture ponds lack wave-damping capabilities and are susceptible to storm surges that could cause aquaculture organisms to escape. Existing plant-based submerged dike structures only achieve physical wave-damping and do not form a material cycle with the aquaculture system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-layered wave-damping structure based on mangrove roots and aquaculture ponds includes a soil layer, a slope fixedly connected to one side of the soil layer, an aquaculture pond fixedly connected to the other side of the soil layer, a protective mechanism installed on the top of the soil layer, and a dredging component installed on the top of the soil layer; the protective mechanism includes multiple mangrove trunks, mangrove roots at the bottom of the multiple mangrove trunks, a first protective slope fixedly connected to the top of the soil layer, a second protective slope fixedly connected to one side of the first protective slope, a third protective slope fixedly connected to one side of the second protective slope, and a drainage component installed on the inner wall of the second protective slope;

[0008] Through the above technical solution, the mangrove roots at the base of multiple mangrove trunks can form a root system to mitigate the impact of waves as they rise to the soil surface. The installation of the first, second, and third protective slopes increases the strength of the protection through tiered protection. As the waves continue to surge towards the soil surface, the first protective slope provides initial resistance. Furthermore, the inner walls of the first, second, and third protective slopes are all equipped with identical drainage components. These components collect filtered seawater and channel it through drainage pipes to the inner wall of the aquaculture pond. Simultaneously, drainage components are installed on the inner wall of the second protective slope. As the waves gradually increase, the drainage components on the second protective slope can stop the water from flowing towards the third protective slope.

[0009] As a further description of the above technical solution:

[0010] The dredging assembly includes a fixing plate, the outer surface of which is fixedly connected to the top of the soil layer. A drive motor is fixedly connected to the outer wall of the fixing plate. A rotating rod is fixedly connected to the drive end of the drive motor. A transmission rod is rotatably connected to the other end of the rotating rod. A slider is rotatably connected to the outer wall of the transmission rod. A connecting plate is rotatably connected to the other end of the transmission rod.

[0011] The above technical solution works as follows: when seawater flows into the aquaculture pond through the dredging pipe, and when the seawater leaves behind silt, the drive motor starts. The start of the drive motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the transmission rod to retract. The retraction of the transmission rod causes the slider to slide on the inner wall of the groove inside the fixed plate, thereby driving the connecting plate to move. This provides power for the connecting plate to drive the scraper to scrape and remove silt from the surface of the soil layer, thus achieving the purpose of silt removal.

[0012] As a further description of the above technical solution:

[0013] A scraper is fixedly connected to the bottom of the connecting plate, and the outer wall of the slider is slidably connected to the inner wall of the fixed plate.

[0014] Through the above technical solution: when the transmission rod drives the connecting plate to move, since the bottom of the connecting plate is fixedly connected to the scraper, it can drive the scraper to move and scrape the surface of the soil layer to remove silt. The sliding block on the inner wall of the fixed plate can ensure the stability of the connecting plate movement, so that the scraper can better remove the silt on the surface of the soil layer and improve the silt removal effect.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the fixing plate is provided with a sliding groove, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0017] The above technical solution provides a track for the slider to slide, allowing the slider to slide along a specific trajectory on the inner wall of the fixed plate. This ensures the accuracy and stability of the transmission rod driving the connecting plate, enabling the scraper to more effectively clean the silt on the surface of the soil layer during the dredging process and improving the working efficiency of the dredging components.

[0018] As a further description of the above technical solution:

[0019] The drainage assembly includes a drainage box, which is fixedly connected to the second protective slope. A drainage pipe is fixedly connected to the bottom of the drainage box, and a water stop valve is fixedly connected to the bottom of the drainage pipe.

[0020] Through the above technical solution: after the first protective slope initially blocks and filters the waves, seawater enters the inner wall of the drainage box through the drain outlet, then flows out through the drain pipe to the inner wall of the dredging pipe, and then flows into the inner wall of the aquaculture pond through the dredging pipe. When the waves continue to rise, the water stop valve inside the drain pipe on the rear side of the first protective slope is activated to close the flow of water inside the drain pipe. Meanwhile, the drain pipe and water stop valve at the bottom of the drainage box of the second protective slope can control the water flow according to the wave height when the waves surge into the second protective slope, stopping the water flow when necessary, allowing the water to continue to flow towards the third protective slope, thus playing a role in tiered protection.

[0021] As a further description of the above technical solution:

[0022] The inner wall of the second protective slope is provided with a drainage outlet, and the drainage box is installed on the outer wall of the drainage outlet;

[0023] Through the above technical solution: after the waves pass through the initial obstruction of the first protective slope, the seawater will flow through the drainage outlet opened on the inner wall of the second protective slope into the drainage box installed on the outer wall of the drainage outlet. The cooperation between the drainage outlet and the drainage box can collect the filtered seawater, which is convenient for the seawater to be discharged into the drainage pipe through the drainage pipe, thereby realizing the collection and discharge of seawater and providing a channel for seawater to flow into the aquaculture pond.

[0024] As a further description of the above technical solution:

[0025] A drainage pipe is fixedly connected to the top of the soil layer, and the bottom end of the drainage pipe is fixedly connected to the inside of the drainage pipe.

[0026] Through the above technical solution, the seawater discharged from the drainage pipe in the drainage component will flow into the dredging pipe fixedly connected to the top of the soil layer. The dredging pipe can collect and transport the seawater flowing out of the drainage pipe, and guide the seawater smoothly into the aquaculture pond, realizing the rational use of seawater, while also ensuring the smooth operation of the entire drainage system.

[0027] As a further description of the above technical solution:

[0028] A filter screen is fixedly connected to the inner wall of the first protective slope, and a filter is fixedly connected to the top of the soil layer.

[0029] Through the above technical solution: when waves crash against the first protective slope, the filter screen inside the slope will initially filter out debris and some impurities from the waves, reducing the amount of impurities entering the subsequent drainage system. Furthermore, when seawater flows through the dredging pipes and the surface of the soil layer into the inner wall of the aquaculture pond, the filter fixedly connected to the top of the soil layer will further filter the seawater, making the seawater entering the aquaculture pond cleaner, which is beneficial to the growth environment of the organisms in the pond and improves the quality of seawater utilization.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the mangrove roots at the base of multiple mangrove trunks form a root system to mitigate the impact of ocean waves and reduce their intensity. As the waves continue to surge towards the surface of the soil layer, the first, second, and third protective slopes converge, thus providing tiered protection. Seawater enters the inner wall of the drainage box through the drainage outlet, then flows out through the drainage pipe to the inner wall of the dredging pipe, and then flows into the inner wall of the aquaculture pond. The collected seawater then flows into the interior of the aquaculture pond through the drainage components. This combines ecological protection with wave-damping structure, resulting in better wave-damping effect while also better protecting the ecosystem.

[0032] 2. In this utility model, the drive motor starts, which drives the rotating rod to rotate. The rotation of the rotating rod causes the transmission rod to retract. The retraction of the transmission rod causes the slider to slide on the inner wall of the groove opened inside the fixed plate, thereby driving the connecting plate to move. This causes the connecting plate to drive the scraper to scrape and remove silt from the surface of the soil layer, keeping the surface of the soil layer clean. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-layered wave-damping structure based on mangrove roots and an aquaculture pond 4, including a soil layer 1. The soil layer 1 is the foundation of the entire structure, providing support and installation foundation for other components. A slope 5 is fixedly connected to one side of the soil layer 1. The slope 5 is in direct contact with the waves and bears the impact force of the waves. An aquaculture pond 4 is fixedly connected to the other side of the soil layer 1. The aquaculture pond 4 is used for aquaculture and is an important component of the entire structure. A protective mechanism 2 is installed on the top of the soil layer 1. The protective mechanism 2 can block and protect the waves, protecting the soil layer 1 and the aquaculture pond 4.

[0042] Specifically, soil layer 1 serves as the foundation, providing installation conditions for the aforementioned protective structure 2. One side of soil layer 1 is connected to slope 5 to withstand the impact of sea waves. Furthermore, protective structure 2 adopts a tiered protection structure to adapt to different wave intensities, resulting in higher protection strength. One side of soil layer 1 is connected to aquaculture pond 4 for aquaculture, which together with protective structure 2 constitutes ecological management, improving both the protection effect and ecological protection. Protective structure 2 is installed on top of soil layer 1 to block and protect sea waves, protecting soil layer 1 and aquaculture pond 4, and combining wave dissipation and aquaculture functions.

[0043] A dredging component 3 is installed on the top of the soil layer 1. The dredging component 3 can clean the silt remaining on the surface of the soil layer 1 to ensure the normal operation of the protective structure. The protective mechanism 2 includes multiple mangrove trunks 21, which can form a certain blocking effect. Mangrove roots 22 are set at the bottom of the multiple mangrove trunks 21, which can form a root system to reduce the impact of the waves. A first protective slope 24 is fixedly connected to the top of the soil layer 1. The first protective slope 24 is the first line of defense of the protective mechanism 2, which initially blocks the waves. A second protective slope 25 is fixedly connected to one side of the first protective slope 24. When the first protective slope 24 cannot completely block the waves, the second protective slope 25 continues to protect the waves. A third protective slope 26 is fixedly connected to one side of the second protective slope 25. The third protective slope 26 is used to provide more stable protection for the waves when they are impacted or their height continues to increase.

[0044] Specifically, the top of the soil layer 1 is equipped with a dredging component 3, which can clean the residual silt on its surface and ensure the normal operation of the protective structure. The protective mechanism 2 consists of multiple parts: multiple mangrove trunks 21 and mangrove roots 22 at their base, which can block the waves and reduce the impact; the first protective slope 24 at the top of the soil layer 1 serves as the first line of defense, initially blocking the waves; the second protective slope 25 on one side of the first protective slope 24 provides continuous protection when the first line of defense fails; and the third protective slope 26 on one side of the second protective slope 25 is used to provide more stable protection against the waves when they are impacted or when their height continues to increase.

[0045] The inner wall of the second protective slope 25 is equipped with a drainage component 27, which can drain and stop seawater. The drainage component 27 includes a drainage box 271 for collecting seawater. The drainage box 271 is fixedly connected to the second protective slope 25. A drainage pipe 273 is fixedly connected to the bottom of the drainage box 271 for transporting seawater. A stop valve 275 is fixedly connected to the bottom of the drainage pipe 273. The stop valve 275 can close the drainage pipe 273 when necessary to prevent seawater backflow. The inner wall of the second protective slope 25 has drainage openings. The outlet 272 provides a channel for seawater to enter the drainage box 271. The drainage box 271 is installed on the outer wall of the outlet 272. The top of the soil layer 1 is fixedly connected to the dredging pipe 274, which is used to transport seawater to the aquaculture pond 4. The bottom end of the drain pipe 273 is fixedly connected to the inside of the dredging pipe 274. The inner wall of the first protective slope 24 is fixedly connected to the filter screen 23, which can filter impurities in the seawater. The top of the soil layer 1 is fixedly connected to the filter 6, which can further filter the seawater and improve the seawater quality.

[0046] Specifically, the inner wall of the second protective slope 25 is equipped with a drainage component 27, which includes a drainage box 271, a drainage pipe 273 and a water stop valve 275. The drainage outlet 272 is the channel for seawater to enter the drainage box 271, which can realize seawater drainage and water stop to prevent backflow. The dredging pipe 274 at the top of the soil layer 1 can transport seawater to the aquaculture pond 4. The bottom end of the drainage pipe 273 is connected to it. The filter screen 23 on the inner wall of the first protective slope 24 can filter impurities in the seawater. At the same time, the filter 6 at the top of the soil layer 1 can further purify the seawater, improve the seawater quality, and ensure the quality of aquaculture water.

[0047] Reference Figure 2 , Figure 4 and Figure 5 The dredging component 3 includes a fixing plate 32, which provides an installation base for other parts of the dredging component 3. The outer surface of the fixing plate 32 is fixedly connected to the top of the soil layer 1. A drive motor 31 is fixedly connected to the outer wall of the fixing plate 32. The drive motor 31 provides power to the dredging component 3. A rotating rod 33 is fixedly connected to the drive end of the drive motor 31. The rotating rod 33 transmits the power of the drive motor 31. A transmission rod 35 is rotatably connected to the other end of the rotating rod 33. The transmission rod 35 moves under the drive of the rotating rod 33.

[0048] Specifically, the dredging component 3 is installed on the fixed plate 32, which is fixed to the top of the soil layer 1. The outer wall of the fixed plate 32 is connected to the drive motor 31 to provide power. The drive end of the drive motor 31 is connected to the rotating rod 33 to transmit power. The other end of the rotating rod 33 is rotatably connected to the transmission rod 35, so that the transmission rod 35 moves under the drive of the rotating rod 33, thereby realizing the power transmission of the dredging component 3.

[0049] The outer wall of the transmission rod 35 is rotatably connected to the slider 36. The slider 36 can slide within the fixed plate 32 under the drive of the transmission rod 35. The other end of the transmission rod 35 is rotatably connected to the connecting plate 37. The connecting plate 37 moves under the drive of the slider 36. The bottom of the connecting plate 37 is fixedly connected to the scraper 34, which is used to scrape off the silt on the surface of the soil layer 1. The outer wall of the slider 36 is slidably connected to the inner wall of the fixed plate 32. The inner wall of the fixed plate 32 is provided with a groove 38, which provides a track for the slider 36 to slide. The outer wall of the slider 36 is slidably connected to the inner wall of the groove 38.

[0050] Specifically, the outer wall of the transmission rod 35 is rotatably connected to the slider 36. Under its drive, the slider 36 slides along the groove 38 in the fixed plate 32. The groove 38 provides a sliding track for the slider 36. The other end of the transmission rod 35 is connected to the connecting plate 37, which moves under the drive of the slider 36. The scraper 34 at the bottom of the connecting plate 37 can scrape off the silt on the surface of the soil layer 1. The dredging function is realized through the linkage of various components.

[0051] Working principle: When waves impact the slope 5 and rise to the surface of the soil layer 1, the mangrove roots 22 at the base of multiple mangrove trunks 21 form a root system to mitigate the impact of the waves and reduce their intensity. It is important to note that the inner walls of the first protective slope 24, the second protective slope 25, and the third protective slope 26 are all equipped with the same drainage components 27. Then, as the waves continue to surge towards the surface of the soil layer 1, the first protective slope 24 provides initial resistance to the waves. The filter screen 23 inside the first protective slope 24 performs preliminary filtration of debris and impurities within the waves. Finally, the seawater enters the drainage box through the drainage outlet 272. The water flows through the inner wall of the first protective slope 271, and then through the drain pipe 273 to the inner wall of the drainage pipe 274. From there, it flows into the inner wall of the aquaculture pond 4. When the waves continue to rise, the stop valve 275 inside the drain pipe 273 on the rear side of the first protective slope 24 is activated to close the flow of water on the inner wall of the drain pipe 273. At this time, the waves will surge into the inner wall of the second protective slope 25. When the waves continue to rise, the drainage component 27 inside the second protective slope 25 will stop the water flow, allowing the water to continue to flow towards the third protective slope 26. This is done by increasing the strength of the protection through step-by-step protection. The collected seawater will then flow into the interior of the aquaculture pond 4 through the drainage component 27.

[0052] Then, when seawater flows through the dredging pipe 274 through the surface of soil layer 1 into the inner wall of aquaculture pond 4, filter 6 will perform a preliminary filtration of the seawater. Then, the seawater will have residual silt. At this time, drive motor 31 starts. The start of drive motor 31 drives rotating rod 33 to rotate. The rotation of rotating rod 33 drives transmission rod 35 to retract. The retraction of transmission rod 35 will drive slider 36 to slide on the inner wall of sliding groove 38 inside fixed plate 32, thereby driving connecting plate 37 to move. Thus, connecting plate 37 drives scraper 34 to scrape and remove silt from the surface of soil layer 1.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
