Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a modular floating artificial reef system. Background Technology

[0002] Artificial reefs are man-made structures placed in the sea to improve the marine ecological environment, create a good habitat for marine life, and provide places for fish and other marine organisms to reproduce, grow, forage, and shelter from predators, thereby achieving the goals of protection, propagation, and increased fish catch.

[0003] Traditional artificial reefs are mostly fixed to the seabed using concrete box structures or abandoned ship hulls, which have the following drawbacks: they are limited by seabed geological conditions (such as silty seabeds which are prone to sinking); their structure and function are limited and lack three-dimensional ecological space; they cannot be dynamically adjusted with changes in the marine environment; and they lack quantitative monitoring methods for ecological effects. Summary of the Invention

[0004] The purpose of this invention is to provide a modular floating artificial reef system that solves the problems existing in traditional artificial reefs in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular floating artificial reef system, comprising a modular buoyancy unit, an ecological functional unit, a dynamic anchoring unit, and a monitoring system; the modular buoyancy unit is disposed above the dynamic anchoring unit, the dynamic anchoring unit is disposed on the side of the ecological functional unit, and the monitoring system is disposed inside the ecological functional unit.

[0006] The modular buoyancy unit is used to stably suspend the reef in a designated water layer.

[0007] The ecological functional units are used to provide a three-dimensional space for marine organisms to inhabit, attach, and reproduce, and to simulate the natural marine environment.

[0008] The dynamic anchoring unit is used to keep the artificial reef stable in a designated sea area.

[0009] The monitoring system is used for the quantitative management of the environment and ecological effects surrounding the artificial reef.

[0010] Preferably, the modular buoyancy unit has an outer layer of corrosion-resistant high-density polyethylene shell, and an inner layer comprising a sealed air chamber and a counterweight chamber, with the sealed air chamber located on the upper layer and the counterweight chamber on the lower layer. An air inlet valve and a mechanical pressure relief valve are installed on the side of the sealed air chamber, which is filled with compressed air. Several flow dividers are installed inside the counterweight chamber, each with several guide holes. A solenoid valve is installed below the counterweight chamber. The corrosion-resistant high-density polyethylene shell improves the corrosion resistance of the modular buoyancy unit. Compressed air is introduced into the sealed air chamber through the air inlet valve to provide buoyancy, and the mechanical pressure relief valve is used to maintain the pressure of the sealed air chamber within a safe range. The flow dividers have several guide holes to guide water entering the counterweight chamber, and the solenoid valve is used to control the water injection and drainage volume.

[0011] Preferably, the ecological functional unit includes several hexagonal main frames, with several triangular trusses installed inside each hexagonal main frame. Several artificial seaweed planting troughs are set within the triangular trusses, using carbon fiber to simulate the morphology of Sargassum. Spherical connectors are installed on the outer sides of the hexagonal main frames. The hexagonal main frames are connected to each other via spherical connectors to form a three-dimensional fractal topology frame. A monitoring system is installed on the triangular trusses. The hexagonal main frames and triangular trusses are manufactured to incorporate artificial seaweed planting troughs with carbon fiber to simulate Sargassum, recreating a natural seaweed farm environment. This provides fish with a place to forage and hide from predators, while simultaneously improving local water quality (increasing dissolved oxygen) through seaweed photosynthesis. The modules are connected by spherical connectors, allowing for slight angle adjustments under wind and waves, buffering the impact of water flow and waves on the frame, preventing structural damage, and minimizing disturbance to attached organisms.

[0012] Preferably, the hexagonal main frame is assembled from six HDPE steel pipes. The hexagonal main frame assembled from HDPE steel pipes has good compressive strength and corrosion resistance.

[0013] Preferably, the hexagonal main frame and triangular truss surfaces are covered with a bio-attachment substrate and laser-engraved with biomimetic grooves. The surface of the bio-attachment substrate has a microporous structure, and the inner layer contains slow-release trace elements. The depth of the laser-engraved biomimetic grooves is 2-5 mm, and the spacing is irregularly distributed. The bio-attachment substrate is made of oyster shell powder or HDPE composite material, with a surface roughness Ra≥6.3μm, porosity>65%, and a surface microporous structure of 50-200μm. The microporous structure of the bio-attachment substrate provides "anchoring points" for attaching organisms such as algae and shellfish, while the slow-release trace elements provide nutrients for biological growth, accelerating the formation of coral, oyster, and other biological communities.

[0014] Preferably, the ball connector has a built-in damping rubber pad. The damping rubber pad can improve the cushioning effect of the ball connector.

[0015] Preferably, the dynamic anchoring unit includes a flexible mooring chain and a seabed adsorption anchor. The seabed adsorption anchor is connected to the triangular truss of the outermost ecological functional unit via the flexible mooring chain, and a lifting chain connects the corrosion-resistant high-density polyethylene shell to the flexible mooring chain. The flexible mooring chain provides pre-tension, and the seabed adsorption anchor provides safe, reliable, and durable pull-out resistance.

[0016] Preferably, the elastic mooring chain uses a multi-layer composite cable, with the outer layer made of polyester fiber and the inner core reinforced with carbon fiber. The use of a multi-layer composite cable allows for a pretension adjustment range of 10-50 kN.

[0017] Preferably, the seabed adsorption anchor is a dynamic anchor or a vacuum negative pressure anchor pile. The seabed adsorption anchor has a diameter of 1-1.5m and strong pull-out resistance.

[0018] Preferably, the monitoring system is equipped with a multi-parameter water quality sensor and a wide-angle underwater camera. The multi-parameter water quality sensor is used to monitor pH, dissolved oxygen, and chlorophyll a. The wide-angle underwater camera features an AI fish recognition algorithm with an accuracy of ≥92%.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention adapts to various seabed types, such as silt, sand, and rock, through a dynamic anchoring unit, eliminating the need for anchoring to the seabed and solving the problem of traditional artificial reefs being prone to sinking in silt seabeds.

[0021] The modular buoyancy unit double-chamber structure ensures that the artificial reef is always in a water layer suitable for biological survival, avoiding the poor ecological effects caused by the "fixed depth that cannot adapt to environmental changes" of traditional artificial reefs.

[0022] Fractal topological frameworks provide multi-layered, porous environments, increasing the habitat area for organisms and providing three-dimensional ecological space.

[0023] By acquiring real-time water quality and biological activity data through monitoring units, the problem of "unquantifiable ecological effects" of traditional artificial reefs can be solved. Attached Figure Description

[0041] Preferably, the ecological functional unit 2 includes several hexagonal main frames 201, with several triangular trusses 202 installed inside each hexagonal main frame 201. Several artificial seaweed planting troughs 204 are set inside the triangular trusses 202, using carbon fiber to simulate the morphology of Sargassum. Spherical connectors 203 are installed on the outside of the hexagonal main frames 201. The hexagonal main frames 201 are connected to each other via the spherical connectors 203 to form a three-dimensional fractal topology frame. A monitoring system 4 is installed on the triangular trusses 202. The hexagonal main frames 201 and triangular trusses 202 are manufactured to incorporate artificial seaweed planting troughs 204 and carbon fiber to simulate Sargassum, recreating a natural seaweed farm environment. This provides a place for fish to forage and hide from predators, while simultaneously improving local water quality (increasing dissolved oxygen) through seaweed photosynthesis. The modules are connected by spherical connectors 203, allowing for slight angle adjustments under wind and waves, buffering the impact of water flow and waves on the frame, preventing structural damage, and reducing disturbance to attached organisms.

[0042] Preferably, the hexagonal main frame 201 is assembled from six HDPE steel pipes. The hexagonal main frame 201 assembled from HDPE steel pipes has good compressive strength and corrosion resistance.

[0043] Preferably, the hexagonal main frame 201 and the triangular truss 202 have a bio-attachment substrate on their surfaces, with laser-engraved biomimetic grooves.

The microporous structure of the bio-attachment substrate provides "anchoring points" for attaching organisms such as algae and shellfish, while the slow-release trace elements provide nutrients for biological growth, accelerating the formation of coral, oyster, and other biological communities.

[0044] Preferably, the ball connector 203 has a built-in damping rubber pad. The damping rubber pad can improve the cushioning effect of the ball connector 203.

[0045] Preferably, the dynamic anchoring unit 3 includes an elastic mooring chain 301 and a seabed adsorption anchor 302.

[0048] Preferably, the monitoring system 4 is equipped with a multi-parameter water quality sensor and a wide-angle underwater camera. The multi-parameter water quality sensor is used to monitor pH, dissolved oxygen, and chlorophyll a. The wide-angle underwater camera features an AI fish recognition algorithm with an accuracy of ≥92%.

[0049] This embodiment achieves stable suspension, ecological restoration, and environmental monitoring of floating artificial reefs through the coordinated operation of four core modules: dynamic anchoring, modular buoyancy adjustment, ecological function carrying capacity, and multi-point intelligent monitoring.

[0050] 1. Dynamic anchoring of ecological functional units: dual constraints to achieve spatial fixation of the system

[0051] Seabed anchoring foundation: The seabed adsorption anchor 302 (dynamic anchor or vacuum negative pressure anchor pile with a diameter of 1-1.5m ecological functional unit) of dynamic anchoring unit 3 is implanted into the seabed of the target sea area, using its strong pull-out force to provide the "bottom fixing point" of ecological functional unit; the seabed adsorption anchor 302 is directly connected to the outermost triangular truss 202 of ecological functional unit 2 through the elastic mooring chain 301 (outer layer polyester fiber, inner carbon fiber reinforced core, pretension ecological functional unit 10-50kN adjustable ecological functional unit), which restricts the overall drift of ecological functional unit 2, while allowing ≤15% of the ecological functional unit's wind and wave swing amplitude, avoiding structural breakage caused by rigid fixation.

[0052] Buoyancy Unit Cooperative Constraint: Modular buoyancy unit 1 (outer layer is corrosion-resistant ecological functional unit HDPE ecological functional unit shell) is connected to elastic mooring chain 301 through suspension chain, forming a linkage constraint relationship of ecological functional unit "buoyancy unit ecological functional unit - ecological functional unit mooring chain ecological functional unit - ecological functional unit ecological functional unit 2". The ecological functional unit not only uses the suspension characteristics of the buoyancy unit to balance part of the weight of ecological functional unit 2, but also enhances the synergy between the buoyancy unit and the main body of the system through suspension chain, avoiding the buoyancy unit from drifting alone, and further improving the overall stability of the system.

[0053] 2. Modular buoyancy adjustment of ecological functional units: precise control of suspension depth

[0054] Buoyancy Ecological Functional Unit - Ecological Functional Unit Counterweight Coupling Drive: The inner layer of the modular buoyancy unit 1 is divided into an upper sealed air chamber 101 and a lower counterweight chamber 102. The sealed air chamber 101 is filled with 0.2-0.5MPa compressed air through the air inlet valve 104, providing 80% of the total buoyancy of the ecological functional unit, laying the foundation for the system's suspension. The counterweight chamber 102 has a built-in diversion plate 106 with guide holes 107 (to guide water flow evenly in and out), and the water volume is controlled by the bottom solenoid valve 108 (injection / discharge accuracy ±5L). Combined with the ecological functional unit PID ecological functional unit algorithm, the adjustable counterweight ratio of ecological functional unit 1:1.2 is dynamically adjusted to balance buoyancy and the total weight of the system.

[0055] Depth Adaptation: By setting the target water layer through the control terminal (e.g., the 10m ecological functional unit in summer avoids strong sunlight, and the 8m ecological functional unit in winter adapts to the thermocline), the system can respond to environmental changes in real time (e.g., the movement of the thermocline). The water volume in the counterweight tank 102 is finely adjusted through the solenoid valve 108, so that the reef is stably suspended in the set water layer with a depth error of ≤±0.5m. At the same time, the mechanical pressure relief valve 105 of the sealed air chamber 101 can automatically release pressure when the pressure inside the chamber exceeds the limit, and the air intake valve 104 replenishes air to ensure long-term stable buoyancy and avoid depth loss due to abnormal air pressure.

[0056] 3. Ecological Functional Units Ecological Functional Unit 2: Constructing a Bionic Three-Dimensional Habitat

[0057] The fractal frame supports the space: The ecological functional unit 2 is based on the hexagonal main frame 201 assembled from ecological functional unit HDPE ecological functional unit steel pipes. Through the spherical connector 203 with built-in damping rubber pads, the secondary triangular trusses 202 (which can be densified as needed) are connected to form a three-dimensional fractal topological frame arranged according to the von Koch curve, forming a multi-layered and porous three-dimensional space. The frame surface is laser-engraved with biomimetic grooves of ecological functional unit 2-5mm depth and irregular spacing to further refine the micro-habitat environment and adapt to the survival needs of organisms of different sizes such as plankton, fish, and benthic organisms.

[0058] Biological attachment and environmental simulation: The hexagonal main frame 201 and the triangular truss 202 are covered with oyster shell powder ecological functional units / ecological functional unit HDPE ecological functional unit composite bio-based material (roughness Ra≥6.3μm, porosity>65%). The surface layer of ecological functional units with a microporous structure of 50-200μm provides ecological functional units "anchoring points" for algae and shellfish. The inner layer slowly releases trace elements such as Fe, Si, and Ca ecological functional units to provide energy for biological growth. At the same time, the artificial seaweed planting trough 204 in the triangular truss 202 is equipped with carbon fiber with adjustable ecological functional units of 1-3m to simulate Sargassum, restore the natural seaweed field environment, and increase local dissolved oxygen through seaweed photosynthesis, providing a place for fish to forage and avoid predators.

[0059] Wave impact buffering: The damping rubber pad built into the ball connector 203 can adjust the frame angle slightly under the action of wind and waves, buffering the impact of water flow on ecological functional unit 2, reducing disturbance to attached organisms (such as corals and algae), and ensuring the stable growth of biological communities.

[0060] 4. Intelligent monitoring of ecological functional units: quantification of ecological and environmental data at multiple locations.

[0061] Distributed data acquisition: Monitoring system 4 is deployed inside ecological functional unit 2 and on triangular truss 202, forming a distributed monitoring network of ecological functional units near the frame. Ecological functional unit-to-ecological functional unit multi-parameter water quality sensors collect water quality indicators such as pH, dissolved oxygen, and chlorophyll a in real time, capturing changes in the surrounding water environment; wide-angle underwater camera (equipped with ecological functional unit AI fish recognition algorithm, with an accuracy of ≥92%) automatically counts fish species, numbers, and activity range, and simultaneously observes coral attachment and algae growth status.

[0062] Data feedback and control support: The collected water quality and biological activity data are transmitted back to the management platform through the LoRa ecological functional unit wireless transmission module. On the one hand, this quantitatively assesses the ecological restoration effect (such as the increase of fishery resources and the rate of biological attachment), and on the other hand, it provides data support for the depth adjustment of buoyancy units (such as following the thermocline) and the optimization of ecological modules (such as the densification of triangular truss 202), realizing the ecological functional unit closed loop of "monitoring ecological functional unit - ecological functional unit evaluating ecological functional unit - ecological functional unit control".

[0063] Example 2

[0064] Please see Figure 3-4Based on Embodiment 1, a modular buoyancy unit 1 is set up and placed above the ecological functional unit 2. The modular buoyancy unit 1 is connected to the middle of the ecological functional unit 2 via a suspension chain, and the monitoring system 4 is installed on the suspension chain.

[0065] Based on the core mechanism of "dynamic anchoring, buoyancy adjustment, ecological carrying capacity of ecological functional units, and intelligent monitoring" in Example 1, Example 2 further improves the system's suspension stability and monitoring coverage by optimizing the connection method of modular buoyancy unit 1 and the deployment location of monitoring system 4.

[0066] 1. Dynamic anchoring of ecological functional units: Continuing the basic fixed logic, adapting to the new connection of buoyancy units.

[0067] The dynamic anchoring core structure (seabed adsorption anchor 302 ecological functional unit + ecological functional unit elastic mooring chain 301) of Embodiment 1 is adopted: the seabed adsorption anchor 302 is implanted into the seabed to provide pull-out resistance, and the elastic mooring chain 301 connects the seabed adsorption anchor 302 and the outermost triangular truss 202 of the ecological functional unit 2 to maintain the overall positioning of the system in the set sea area and allow small-amplitude swaying in wind and waves to buffer the impact; unlike Embodiment 1, in this embodiment, the modular buoyancy unit 1 is no longer connected to the elastic mooring chain 301 through the suspension chain, but is directly linked with the ecological functional unit 2. The anchoring unit only focuses on the bottom fixing of the ecological functional unit 2, simplifying the constraint relationship while ensuring the fixing effect.

[0068] 2. Modular buoyancy adjustment of ecological functional units: concentrated force at a single point enhances suspension stability.

[0069] More direct buoyancy transfer: Only one modular buoyancy unit 1 is set up for ecological functional unit 1, and it is directly connected to the middle ecological functional unit of ecological functional unit 2 through a hanging chain. Compared with the indirect linkage of ecological functional units in embodiment 1, which is "buoyancy unit ecological functional unit - ecological functional unit mooring chain ecological functional unit - ecological functional unit ecological functional unit 2", the connection method of ecological functional units in this embodiment, which is "buoyancy unit ecological functional unit - ecological functional unit hanging chain ecological functional unit - ecological functional unit ecological functional unit 2 middle", can transfer buoyancy more evenly and directly to the whole ecological functional unit 2, reduce the frame tilting caused by uneven force, and improve the stability of the system's suspension posture.

[0070] The buoyancy adjustment mechanism remains unchanged: it still relies on the dual-chamber structure of the ecological functional unit "sealed air chamber 101 (providing 80% of the total buoyancy of the ecological functional unit) + ecological functional unit counterweight chamber 102 (solenoid valve 108 controls water volume ecological functional unit + ecological functional unit PID ecological functional unit algorithm)" to achieve precise suspension and depth adaptation of the set water layer (error ≤ ±0.5m). The air intake valve 104 and mechanical pressure relief valve 105 of the sealed air chamber 101 ensure the safety and stability of buoyancy. The core adjustment logic is consistent with that of Example 1.

[0071] 3. Ecological Functional Unit 2: Maintaining biomimetic load-bearing capacity and adapting to new buoyancy connections.

[0072] The core ecological function design of Example 1 is completely retained: the HDPE ecological function unit hexagonal main frame 201, the spherical connector 203 with damping rubber pads, the densifiable triangular truss 202, the composite bio-based material (containing slow-release trace elements), and the carbon fiber simulated Sargassum algae structure remain unchanged. A three-dimensional habitat space is still constructed through a fractal topology framework to promote biological attachment and natural environment simulation, buffer against wind and wave impacts, and ensure the effectiveness of ecological restoration. The only difference is the addition of a lifting port in the middle of ecological function unit 2 that connects to modular buoyancy unit 1. This interface does not affect the ecological space or biological habitat; it is only used for buoyancy transfer.

[0073] 4. Intelligent monitoring of ecological functional units: Optimize deployment locations and expand monitoring coverage.

[0074] More flexible monitoring locations: The monitoring system 4 has been adjusted from the ecological functional unit "ecological functional unit 2 inner ecological functional unit + ecological functional unit triangular truss 202" in Example 1 to the ecological functional unit "deployed on the suspension chain" - the ecological functional unit suspension chain connects the middle of ecological functional unit 2 and the buoyancy unit, located in the core area of ​​the system, and can cover a larger area of ​​water around ecological functional unit 2. This avoids the monitoring equipment occupying the habitat space of organisms, and can collect more comprehensive water quality data (pH, dissolved oxygen, chlorophyll ecological functional unit a) and biological activity images (AI ecological functional unit fish recognition); at the same time, the monitoring data is still transmitted back to the management platform through the ecological functional unit LoRa ecological functional unit module to support system regulation, and the data processing and feedback logic is consistent with Example 1.

[0075] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
