[0020] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0021] Refer to Figure 1 , Figure 2 and Figures 7 - 9 As shown, an artificial fish reef in an embodiment of the present disclosure includes a plurality of artificial fish reef bodies 1. A plurality of concave sunken holes 11 are formed on the surface of each artificial fish reef body 1. The plurality of artificial fish reef bodies 1 are spliced to form a fish reef configuration, and a fish shelter cavity 10 is formed at the center of the fish reef configuration. The fish reef configuration is provided with a plurality of flow-through holes 12, and the plurality of flow-through holes 12 all penetrate through the inner wall and the outer wall of the fish reef configuration to realize the water flow exchange between the fish shelter cavity 10 and the external space of the fish reef configuration. The artificial fish reef further includes a flow field regulation system 2, which includes a monitoring device, a dynamic regulation device, and a power supply device. The monitoring device is integrated in the flow-through hole 12 and is used for collecting water flow data in real time. The dynamic regulation device is arranged at the flow-through hole 12 and is used for adjusting the opening degree of the flow-through hole 12 according to the water flow data. The power supply device is electrically connected to the dynamic regulation device and is used for supplying power to the dynamic regulation device.

[0022] In this embodiment, a plurality of concave counterbores 11 are formed on the surface of each fish reef body 1. This design provides rich habitats, foraging places and shelters for marine organisms. A plurality of fish reef bodies 1 form a specific stable and expandable fish reef configuration by splicing. A fish shelter cavity 10 is formed at the central position of the fish reef configuration, providing a relatively safe habitat space for fish, reducing external interference and natural enemy threats, and being beneficial to the survival and reproduction of fish. This splicing design facilitates the assembly between individual fish reef bodies 1, enabling them to be used either as independent reefs or as group reefs after splicing and assembly. It can be understood that the shape of the fish reef body 1 can be adaptively designed according to actual usage requirements to ensure its stable placement and the formation of the required fish reef configuration, as long as the size and shape of the fish shelter cavity 10 meet the standards. In the embodiments shown in this disclosure, the shape of a single fish reef body 1 is taken as an example of being approximately frustum-shaped. The inner wall and outer wall of the fish reef body 1 are both arc-shaped surfaces, and the longitudinal section of the fish reef body 1 is trapezoidal; the fish reef configuration is formed by splicing eight fish reef bodies 1 to form a hollow frustum. Specifically, the longitudinal section of the fish reef body 1 is a right trapezoid, and the right-angled side of the right trapezoid is located on the inner wall of the fish reef body 1, so that the fish shelter cavity 10 is cylindrical. A plurality of flow-through holes 12 are formed on the fish reef configuration. The plurality of flow-through holes 12 penetrate through the inner wall and outer wall of the fish reef configuration. The main function of the flow-through holes 12 is to realize the water flow exchange between the fish shelter cavity 10 and the external space of the fish reef configuration. Through this water flow exchange, seawater rich in nutrients and dissolved oxygen can be introduced into the fish shelter cavity 10, providing sufficient food and oxygen sources for fish; at the same time, the metabolic wastes in the fish shelter cavity 10 can be discharged to maintain a good water quality environment and meet the survival and growth needs of fish. The number of the flow-through holes 12 is at least two, and the two flow-through holes 12 are symmetrically arranged relative to the center of the fish reef configuration. These two flow-through holes 12 can be respectively defined as the front flow-through hole and the rear flow-through hole. The through-flow hydrodynamic layout of the front flow-through hole and the rear flow-through hole realizes the coordinated optimization of reducing the velocity of strong ocean currents and improving the overall stability of the artificial fish reef. It should be noted that the flow-through holes 12 can be formed between two adjacent fish reef bodies 1. For example, arc-shaped grooves are respectively formed on two mutually contacting surfaces of two adjacent fish reef bodies 1 among a plurality of fish reef bodies 1. After these two adjacent fish reef bodies 1 are spliced, the two arc-shaped grooves are buckled and enclosed to form the front flow-through hole; the rear flow-through hole is formed between two fish reef bodies 1 that are symmetrical to the above two adjacent fish reef bodies 1. Arc-shaped grooves are also respectively formed on two mutually contacting surfaces of these two fish reef bodies 1. When these two fish reef bodies 1 are spliced, the two arc-shaped grooves are buckled and enclosed to form the rear flow-through hole. The flow-through holes 12 can also be formed on a single fish reef body 1. For example, the front flow-through hole and the rear flow-through hole are respectively formed on two of a plurality of fish reef bodies 1, and the front flow-through hole and the rear flow-through hole are both arranged avoiding the concave counterbores 11.In addition, an overflow pipe 16 is also provided in the overflow hole 12. The monitoring device is integrated into the overflow hole 12 by being installed in the overflow pipe 16, and can collect water flow data in real time. These water flow data may include key information such as water flow velocity, water temperature, and oxygen content in the water flow. The dynamic adjustment device is fixedly connected to the overflow pipe 16 through the fixing bolt 17, and thus is installed at the position of the overflow hole 12. According to the water flow data collected by the monitoring device, the opening degree of the overflow hole 12 is accurately adjusted. When it is detected that the water flow velocity is too fast or too slow, the water temperature is not suitable, etc., the dynamic adjustment device will correspondingly adjust the opening degree of the overflow hole 12 to optimize the water flow environment in the fish shelter cavity 10 and meet the requirements of different fish for water flow conditions. The power supply device provides stable power support for the dynamic adjustment device to ensure its normal operation. The power supply device includes a power supply 24, a voltage stabilizing module 26, and a power supply cable 25. The power supply 24 can be a submarine cable pre-laid on the seabed, and electric energy is transmitted to the dynamic adjustment device through the power supply cable 25. The voltage stabilizing module 26 can ensure the stability of the supply voltage, optimize the power distribution, avoid damage to the dynamic adjustment device caused by voltage fluctuations, and improve the reliability and stability of the system. It should be noted that when designing the artificial fish reef as a whole, it is necessary to design the spatial structure of the artificial fish reef and the height and spacing of each functional component according to the coral reef environment and fishery resource characteristics and combined with the biological habits.

[0023] In summary, the artificial fish reef of the present disclosure is designed to be spliced, which facilitates the assembly between individual fish reef bodies 1. It can be used as an independent reef or as a group reef after splicing and assembly, forming a splicable artificial fish reef with a central fish shelter cavity 10. Compared with traditional artificial fish reefs, its structure determines that it is lighter in weight, convenient for transportation, placement, production and use, with strong economy and applicability. It can be specifically designed according to the natural environmental factors of the sea area and the functional requirements of the fish reef, and the product compliance is high. The overall structure of the artificial fish reef is substantial, and the spatial layout conforms to the principle of fluid mechanics, which can reduce the impact of scouring and silting on the settlement of the reef body and ensure the stability and use effect of the artificial fish reef; the concave sinkholes 11 and the fish shelter cavity 10 on the surface of the fish reef body 1 provide diverse habitats for marine organisms, which can fully meet the living habit requirements of different organisms, such as diverse ecological function requirements such as coral attachment and fish habitation, and are beneficial to the increase of biodiversity. The overflow hole 12 realizes the water flow exchange between the fish shelter cavity 10 and the outside world, maintains a good water quality environment, and at the same time brings rich nutrients and oxygen into the fish shelter cavity 10, promoting the growth and reproduction of fish. The flow field regulation system 2 can dynamically adjust the opening degree of the overflow hole 12 according to real-time water flow data, create a suitable water flow environment for different types of marine organisms, and improve the attractiveness and adaptability of the artificial fish reef to marine organisms.

[0024] Refer to Figures 3 - 6As shown, in an implementable embodiment, each artificial reef body 1 includes opposite first and second sides. A connecting member 13 is convexly provided on the first side, and a connecting groove 14 is formed on the second side. Two adjacent artificial reef bodies 1 are in plug-in fit through the connecting member 13 and the connecting groove 14.

[0025] Specifically, in an implementable embodiment, a threaded hole 131 is formed in the connecting member 13, and a fixing hole 141 corresponding to the threaded hole 131 is formed in the inner wall of the connecting groove 14. The fixing hole 141 and the threaded hole 131 are fixedly connected by a fastener 15.

[0026] In this embodiment, each artificial reef body 1 has opposite first and second sides, which provides a clear structural basis for the connection between artificial reef bodies 1. Through the connection method of the insertion and cooperation between the connecting member 13 and the connecting groove 14, the operation is simple and fast. During the assembly process of the artificial reef, the staff only needs to align one or more connecting members 13 of one artificial reef body 1 with the corresponding connecting grooves 14 of the adjacent artificial reef body 1, and then insert them to complete the preliminary connection, greatly shortening the assembly time of the artificial reef and improving the construction efficiency. Compared with other complex connection methods, the insertion and cooperation method has relatively low technical requirements for the staff, reduces the construction difficulty, and also reduces the possible errors during the construction process. When the two adjacent artificial reef bodies 1 complete the preliminary insertion and cooperation through the connecting member 13 and the connecting groove 14, it is necessary to further firmly fix them together through the fastener 15. Usually, the fastener 15 can be selected as bolts or screws, etc. These fasteners 15 pass through the fixing holes 141 and are screwed into the threaded holes 131. As the fastener 15 is gradually tightened, the connection between the two artificial reef bodies 1 becomes tighter. In terms of stability, the tight insertion and cooperation and the fastening connection between the connecting member 13 and the connecting groove 14 can effectively enhance the stability of the overall structure of the artificial reef. When subjected to external forces such as seawater flow, tides, and wind and wave impacts, the insertion structure can firmly combine each artificial reef body 1 together to jointly resist external forces and reduce the shaking or displacement of a single artificial reef body 1. This stability not only helps the artificial reef maintain its structural integrity in the marine environment for a long time, but also provides a more stable habitat for marine organisms. For example, for some juvenile fish and coral larvae, a stable habitat can improve their survival probability and promote their growth and reproduction. In addition, this connection method also endows the artificial reef with high flexibility. In practical applications, according to different sea area environments, ecological restoration needs, and fishery resource characteristics, the splicing quantity and layout mode of the artificial reef body 1 can be flexibly adjusted. For example, in a sea area with strong water flow, the number of artificial reef bodies 1 can be increased to form a reef configuration with stronger anti-flow ability through different splicing combinations; in an area where a certain specific marine organism needs to be protected, the splicing method can be adjusted accordingly to create a more suitable habitat space for this organism. It can be understood that due to the modular design of the artificial reef body 1, the size and weight of each artificial reef body 1 are relatively small, which is convenient for production and processing. During transportation, multiple artificial reef bodies 1 can be disassembled and transported to save transportation space and reduce transportation costs; after arriving at the sea area for placement, on-site assembly can be carried out, which is convenient and fast.

[0027] Refer to Figure 10As shown, in an implementable embodiment, the monitoring device includes a temperature monitoring module and a flow monitoring module, and the dynamic adjustment device includes a control module and an electric control valve 21 electrically connected to the control module. Among them, the temperature monitoring module is used to monitor the water flow temperature in the environment and collect water flow temperature data; the flow monitoring module is used to monitor the water flow rate in the environment and collect water flow rate data. The control module is electrically connected to the temperature monitoring module and the flow monitoring module respectively, and is used to generate a control instruction according to the water flow temperature data and the water flow rate data to adjust the electric control valve 21.

[0028] In this embodiment, the temperature monitoring module is responsible for monitoring the water flow temperature in the environment and collecting water flow temperature data. Specifically, the temperature monitoring module may include, but is not limited to, a thermistor sensor, a platinum resistance temperature sensor, a thermocouple sensor, an infrared temperature measurement sensor, a fiber Bragg grating temperature sensor, etc. It uses a high-precision temperature sensor that can quickly and accurately sense the subtle changes in the water flow temperature, providing accurate data support for subsequent regulation. The flow monitoring module is used to monitor the water flow rate in the environment and collect water flow rate data. It uses flow monitoring technologies such as electromagnetic induction, flow sensors, or ultrasonic measurement principles to ensure accurate and reliable monitoring of the water flow rate. The dynamic adjustment device is arranged at the flow-through hole 12 and consists of a control module and an electric control valve 21 electrically connected to the control module. The control module is electrically connected to the temperature monitoring module and the flow monitoring module respectively, and receives the water flow temperature data and the water flow rate data collected by them. The control module is built-in with an intelligent algorithm program that can analyze and process according to the preset parameter range and the actually collected data, and generate corresponding control instructions. These control instructions are used to adjust the opening degree of the electric control valve 21, so as to achieve precise control of the water flow in the flow-through hole 12. The electric control valve 21 specifically includes an electric actuator 211 and a valve body. The electric actuator 211 is used to drive the valve stem to move after receiving the control instruction, driving the valve core to linearly or rotationally displace between the valve seats, thereby changing the cross-sectional area of the fluid passage, that is, changing the cross-sectional area of the flow-through pipe 16, so as to control the water flow in the flow-through pipe 16. For example, when the temperature monitoring module monitors that the water flow temperature is too high or too low, exceeding the range suitable for the survival of marine organisms, or the flow monitoring module finds that the water flow rate is too large or too small, which is not conducive to biological habitation and material exchange, the control module will quickly respond and adjust the opening degree of the electric control valve 21 to make the water flow temperature, flow rate, or flow velocity in the flow-through hole 12 (specifically, the flow-through pipe 16 in the flow-through hole 12) return to a suitable range.

[0029] Refer to Figure 11As shown, in an implementable embodiment, the dynamic adjustment device further includes a communication module, a communication cable 22, and a communication buoy 23. The communication module is electrically connected to the control module. The communication module establishes a data transmission link with the cloud server through the communication cable 22 and the communication buoy 23. Among them, the communication module is used to receive the monitoring information output by the control module according to the water flow temperature data and the water flow rate data. The communication cable 22 is used to transmit the monitoring information. The communication buoy 23 floats on the water surface and is used to receive the monitoring information and upload the monitoring information to the cloud server.

[0030] In this embodiment, the artificial reef realizes data collection and remote management through the cooperation of multiple modules. The communication module is electrically connected to the control module and continuously receives the water environment monitoring information generated by the control module by integrating the water flow temperature data and the water flow rate data. The monitoring information includes multi-dimensional parameters of the internal flow field of the artificial reef, covering both key data such as the current water flow temperature and flow rate, and also including, for example, the real-time operating status of actuators such as the electric control valve 21, providing data support for comprehensively grasping the hydrodynamic characteristics of the artificial reef. The communication cable 22 can specifically adopt a submarine optical fiber communication cable 22 with excellent insulation performance, which is responsible for transmitting the monitoring information. This medium exhibits excellent anti-interference ability and signal fidelity in complex marine environments, ensuring the stable transmission of monitoring data from underwater devices to surface nodes. The communication buoy 23, as a data relay hub on the water surface, continuously floats on the water surface, receives the monitoring information transmitted by the communication cable 22 through wireless or wired means, and uploads the data packet to the cloud server via satellite or mobile communication network. The cloud server, as the data processing center, not only undertakes the function of storing and archiving a large amount of monitoring data, but also supports remote access by researchers and managers through a standardized interface. Relevant users can retrieve the real-time monitoring data stream at any time, conduct trend analysis in combination with professional analysis models, or call historical data sets for comparative analysis, ultimately providing a scientific decision-making basis for the structural optimization, ecological effect evaluation, and operation and maintenance strategy formulation of artificial reefs. A complete link from underwater data collection, sea-air transmission to cloud analysis is realized, and an intelligent artificial reef environment monitoring network is constructed. In summary, through the constructed data transmission link, the real-time upload of the internal flow field data of the artificial reef to the cloud server is realized. Researchers and managers can remotely obtain the operating status of the artificial reef without arriving at the scene, timely understand its impact on the marine ecological environment, and provide a basis for scientific decision-making; after collecting a large amount of real-time data, the cloud server can provide support for the intelligent control of the artificial reef in combination with data analysis technology. For example, according to the variation rules of water flow temperature and flow rate in different seasons and time periods, the preset parameters of the control module can be optimized to enable the artificial reef to better adapt to changes in the marine environment and create more suitable habitat conditions for marine organisms. In addition, real-time data monitoring helps to detect potential faults in the flow field control system 2 of the artificial reef in a timely manner. When abnormal fluctuations occur in the monitoring data, it may indicate problems with monitoring devices, dynamic adjustment devices, or other components. Through data analysis on the cloud server, the fault point can be quickly located, maintenance can be carried out in advance, the impact of equipment damage on marine ecological restoration work can be reduced, and the maintenance cost can be lowered.

[0031] Referring to Figure 12 As shown, in an implementable embodiment, the flow field control system 2 further includes a storage module, which is connected to the control module and used to store the water flow temperature data and the water flow rate data.

[0032] In this embodiment, the storage module is connected to the control module and is used to store the water flow temperature data collected by the temperature monitoring module and the water flow rate data collected by the flow rate monitoring module. It has the characteristics of large-capacity storage and fast reading and writing, can record data in real time, and ensure the integrity and timeliness of the data. The storage module can adopt non-volatile storage technology, so that the data will not be lost even when the system is powered off, forming a traceable data record. By setting up the storage module, the local storage and backup of data are realized. Combined with the cloud storage function of the cloud server, a dual data protection mechanism is formed, avoiding data loss caused by data transmission failures or cloud server problems, accumulating complete data resources for the long-term operation of artificial fish reefs, and ensuring the security and continuity of the data.

[0033] In an implementable embodiment, the fish reef body 1 is made of a composite fiber resin material.

[0034] In this embodiment, the fish reef body 1 of the artificial fish reef is made of an environmentally friendly composite fiber resin material, which will not have a negative impact on the water quality of the sea water and the marine ecological environment. This material has the characteristics of light weight and high strength. Compared with traditional reinforced concrete and steel, its weight is significantly reduced, making the transportation and placement of artificial fish reefs more convenient, reducing the construction difficulty and cost. The composite fiber resin material has excellent seawater corrosion resistance and can be used stably in a complex marine environment for a long time, greatly extending the service life of artificial fish reefs and reducing the maintenance and replacement costs. Its surface has a certain roughness and special texture structure, which is beneficial to the attachment and growth of marine organisms such as coral larvae and shellfish, providing a rich habitat and breeding place for marine organisms and promoting the increase of biodiversity. The composite fiber resin material can be shaped according to actual needs during the production process, facilitating the production of the fish reef body 1 with multiple concave sinkholes 11, and these concave sinkholes 11 further increase the biological attachment area and optimize the ecological function of the fish reef.

[0035] In an implementable embodiment, the concave sinkholes 11 are in the shape of a hexagonal frustum depression, and multiple concave sinkholes 11 are evenly arranged on the surface of the fish reef body 1.

[0036] In this embodiment, the concave sink hole 11 is in the shape of a hexagonal pyramid, which has many advantages. From the perspective of space utilization, the shape of the hexagonal pyramid increases the surface area of ​​the concave structure, which can provide a larger attachment area for marine organisms compared to other simple shapes, and is conducive to the growth and reproduction of attached organisms such as coral larvae and shellfish. The geometric structure of the hexagonal pyramid can also change the flow characteristics of water on the surface of the fish reef body 1 to a certain extent, forming a relatively stable small flow field inside the depression, providing a shelter for small marine organisms to avoid the impact of water flow, and meeting their needs for living and foraging. A plurality of concave sink holes 11 are evenly arranged on the surface of the fish reef body 1, and the uniform arrangement ensures that each area on the surface of the fish reef body 1 can provide similar living conditions for marine organisms, avoiding the situation of uneven biological aggregation. This helps to attract more species and numbers of marine organisms to live on the fish reef and promote the development of biodiversity. At the same time, the uniform arrangement also enhances the stability of the structure of the fish reef body 1, making the artificial fish reef more durable when subjected to seawater scouring and external forces.

[0037] Reference Figure 13 and Figure 14 As shown, the present disclosure also provides a flow field control method for artificial fish reefs, the method comprising: S1, real-time collection of water flow data; S2. Receive water flow data and adjust the opening of the flow hole 12 based on the water flow data.

[0038] In this embodiment, S1: Continuously collect water flow data in real time. The collected water flow data may specifically include physical parameters such as water flow velocity, flow rate, and water density, and may also include chemical parameters such as dissolved oxygen content, turbidity, and pH value in the water, and may further include biological - related parameters such as water temperature. The collection of water flow data can be achieved by continuously collecting water flow dynamic information through a multi - parameter sensor array deployed in the flow - through hole 12. These sensors adopt a modular design and can be configured with different types of probes according to specific monitoring requirements to form a customized data collection solution. In some specific embodiments, the monitoring device integrated in the flow - through hole 12 of the flow field regulation system 2 of the artificial reef shown in the above - mentioned feasible embodiments is used to collect water flow data in real time. S2: Receive the water flow data and adjust the opening degree of the flow - through hole 12 based on the water flow data, including: S21: Generate a control instruction according to the water flow data and adjust the opening degree of the flow - through hole 12. Specifically, the water flow data collected by the monitoring device is transmitted to the control module in the dynamic adjustment device. After receiving these data, the control module will compare and analyze them with a preset range of suitable water flow parameters. The preset parameter range is preset according to the living habits of different marine organisms and the environmental characteristics of the sea area where the artificial reef is located. If the water flow data exceeds the preset range, the control module will generate a corresponding control instruction. The opening degree of the flow - through hole 12 can be adjusted by including but not limited to an electric control valve 21, an underwater electromagnetic control valve, an underwater hydraulic control valve, an underwater pneumatic control valve, or a self - acting control valve, etc. The control instruction generated by the control module will be sent to the above - mentioned control valve connected to the flow - through hole 12, and the control valve adjusts its own opening degree according to the control instruction, thereby adjusting the opening degree of the flow - through hole 12. When the opening degree of the flow - through hole 12 changes, the flow field parameters inside the artificial reef, such as water flow velocity, flow rate, and temperature distribution, will also change accordingly, making it gradually approach a state suitable for the survival of marine organisms. The flow field regulation method of the present disclosure can accurately control the flow field environment inside the artificial reef by collecting water flow data in real time and making targeted adjustments based on the data, meeting the diverse requirements of different marine organisms for water flow temperature and flow rate at different growth stages, improving the survival rate and reproduction rate of marine organisms, and promoting the increase of biodiversity; specifically, it can automatically adjust the opening degree of the flow - through hole 12 according to the real - time changes in the marine environment, making the artificial reef have strong environmental adaptability. Whether it is the change in marine water temperature in different seasons or the difference in water flow conditions in different sea areas, it can create a relatively stable habitat environment for marine organisms.

[0039] Refer to Figure 15 As shown, preferably, S1: Continuously collect water flow data in real time, including: S11: Monitor the water flow temperature in the environment and collect water flow temperature data; S12: Monitor the water flow rate in the environment and collect water flow rate data.

[0040] Among them, S11 monitors the water flow temperature in the environment and collects water flow temperature data. This is achieved by installing a high-precision temperature monitoring module in the water flow hole 12 of the artificial fish reef to collect water flow temperature data. The temperature monitoring module can specifically include, but is not limited to, a thermistor sensor, a platinum resistance temperature sensor, a thermocouple sensor, an infrared temperature measurement sensor, a fiber Bragg grating temperature sensor, etc. This module adopts advanced temperature sensor technology, has the characteristics of fast response and high sensitivity, and can sense the change of water flow temperature in the environment in real time. The temperature monitoring module continuously collects water flow temperature data and transmits these data to the subsequent data processing unit in the form of electrical signals or digital signals. S12 monitors the water flow rate in the environment and collects water flow rate data. This is achieved by installing a flow rate monitoring module in the same water flow hole 12 to collect water flow rate data. The flow rate monitoring module uses mature flow rate monitoring principles, such as the electromagnetic induction principle, ultrasonic measurement technology, or a flow sensor, to monitor the water flow rate in the environment in real time. By accurately measuring parameters such as the flow velocity and cross-sectional area of the water flow, accurate water flow rate data is calculated. The flow rate monitoring module also transmits the collected water flow rate data in a timely manner for subsequent analysis and processing. Therefore, in S21, generating a control instruction based on the water flow data and adjusting the opening degree of the water flow hole 12, the collected water flow temperature data and water flow rate data are transmitted to the control module in the dynamic adjustment device. The control module is built-in with intelligent algorithms and a preset range of suitable water flow parameters, and this range is preset according to the habits of different marine organisms and the environmental characteristics of the sea area where the artificial fish reef is located. The control module compares and analyzes the received real-time water flow temperature data and water flow rate data with the preset parameters. Once it is found that the water flow temperature or flow rate data exceeds the preset range, the control module will quickly generate corresponding control instructions. These control instructions are sent to the regulating valve installed at the water flow hole 12, and the regulating valve accurately adjusts its own opening degree according to the control instructions, thereby achieving precise adjustment of the opening degree of the water flow hole 12. By changing the opening degree of the water flow hole 12, the flow field parameters such as the water flow velocity, flow rate, and temperature distribution inside the artificial fish reef are adjusted to better meet the survival needs of marine organisms.

[0041] Referring to Figure 16 As shown, in an implementable embodiment, the flow field regulation method further includes: S3. Obtaining water flow data and outputting monitoring information; S4. Receiving the monitoring information and uploading it to the cloud server.

[0042] In this embodiment, S3 is to obtain water flow data and output monitoring information. Specifically, the control module obtains the water flow data collected by the multi-parameter sensor array deployed in the flow-through hole 12, integrates and processes these data, and then analyzes and encodes them to generate monitoring information including but not limited to water flow temperature, flow rate, collection time, artificial reef position, etc. The communication module receives the monitoring information output by the control module and transmits the monitoring information to the communication buoy 23 floating on the water surface through the communication cable 22. The communication buoy 23 has a data forwarding function, and it uploads the received monitoring information to the cloud server through wireless communication technology. The cloud server has powerful data storage and processing capabilities and can store, classify, and analyze a large amount of monitoring information. Researchers and managers can remotely access the cloud server through the network to obtain the real-time and historical water flow data of the artificial reef for data analysis and decision-making.

[0043] Referring Figure 17 As shown, in an implementable embodiment, the flow field regulation method further includes: S5. Obtain water flow data and store the water flow data.

[0044] In this embodiment, for the storage of water flow data, storage modules including but not limited to SD cards, industrial-grade Flash memories, or underwater dedicated hard disks can be selected. The storage module usually indirectly obtains the water flow data through the control module and stores it, rather than being directly connected to the monitoring device. The above storage module has the characteristics of large-capacity storage and fast reading and writing, can record data in real time, ensure the integrity and timeliness of the data, and even in the case of system power failure, the data will not be lost, forming a traceable data record. By setting up the storage module, the local storage backup of the data is realized. Combined with the cloud storage function of the cloud server, a dual data protection mechanism is formed, avoiding data loss caused by data transmission failures or cloud server problems, accumulating complete data resources for the long-term operation of the artificial reef, and ensuring the security and continuity of the data; when the data on the cloud server is lost, the user can take out the storage module set underwater to trace the data record.
