Description

Technical Field

[0001] This application relates to flow velocity measurement devices, and more particularly to a flow velocity monitoring device for marine ranches. Background Technology

[0002] The deep-sea aquaculture industry is developing rapidly, and gravity-fed deep-water wave-resistant cages (HDPE frame + netting structure) have become core equipment in modern marine ranching. The safety of the cages and the stability of the aquaculture environment are highly dependent on the marine dynamic environment, among which seawater current velocity and waves are key factors affecting the structural strength of the cages, the stability of the mooring system, and the efficiency of water exchange within the cages. Therefore, real-time and accurate monitoring of the current velocity and waves in the surrounding sea area is crucial.

[0003] Currently, monitoring of ocean ranch current velocity mainly relies on the following technologies:

[0004] An acoustic Doppler current profiler (ADCP) is installed on a seabed observation rack to measure current velocity profiles through acoustic wave reflection and integrates a wave sensor to acquire wave parameters. However, because traditional acoustic Doppler current profilers are connected to surface buoys via fixed cables, these cables are prone to tangling with the anchor cables of the mooring system during deployment or retrieval, leading to damage to the acoustic Doppler current profiler.

[0015] In one embodiment, the marine ranch current velocity monitoring device further includes:

[0016] An acoustic signal receiver is provided on the surface buoy module. The acoustic signal receiver is used to receive the acoustic wave signal of the underwater acoustic beacon and convert the acoustic wave signal into an electrical signal.

[0017] A control module is installed on the surface buoy module. The control module is electrically connected to the acoustic signal receiver, the Beidou positioning beacon or the GPS positioning beacon, and the shore-based main control platform.

[0028] This invention provides a marine ranch current velocity monitoring device, comprising a surface buoy module, a current velocity monitoring module, a first flexible connecting component, and a shear pin. The surface buoy module provides buoyancy support for the entire device, while the current velocity monitoring module is used to monitor marine environmental current velocity parameters in real time. The first flexible connecting component flexibly connects the surface buoy module and the current velocity monitoring module, significantly reducing the risk of interference with the net cage mooring system. Specifically, a shear pin is provided at the connection node between the first flexible connecting component and the current velocity monitoring module. The preset fracture threshold of the shear pin is less than the structural strength limit set by the current velocity monitoring module. When the marine dynamic environment changes or the external force generated by interference with the mooring system exceeds the preset fracture threshold, the shear pin breaks first, causing the current velocity monitoring module to automatically detach from the first flexible connecting component, effectively blocking the transmission of destructive stress to the current velocity monitoring module. This design, through a dual mechanism of flexible connection and overload protection, ensures the normal operation of the current velocity monitoring function while avoiding the problem of entanglement and damage to the current velocity monitoring module caused by traditional fixed connection methods, significantly improving the reliability and economy of the device.

[0034] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0035] See Figure 1 This invention illustrates a preferred embodiment of a marine ranch current velocity monitoring device, comprising:

[0036] Surface buoy module 1, which is used to provide buoyancy support;

[0037] Flow velocity monitoring module 2 is used to monitor the flow velocity of the environment in which the marine ranch is located;

[0038] The first flexible connecting component 3, the first end of the first flexible connecting component 3 is connected to the surface buoy module 1; and

[0039] Shear pin 4, the first end of shear pin 4 is connected to the second end of the first flexible connecting component 3, the second end of shear pin 4 is connected to the flow velocity monitoring module 2, and shear pin 4 is configured to break when the external force exceeds its preset fracture threshold, the preset fracture threshold being less than the structural strength limit of the flow velocity monitoring module 2.

[0040] This invention provides a marine ranching current velocity monitoring device, comprising a surface buoy module 1, a current velocity monitoring module 2, a first flexible connecting component 3, and a shear pin 4. The surface buoy module 1 provides buoyancy support for the entire device, while the current velocity monitoring module 2 is used to monitor marine environmental current velocity parameters in real time. The first flexible connecting component 3 flexibly connects the surface buoy module 1 and the current velocity monitoring module 2, significantly reducing the risk of interference with the net cage mooring system. Specifically, a shear pin 4 is provided at the connection node between the first flexible connecting component 3 and the current velocity monitoring module 2. The preset fracture threshold of the shear pin 4 is less than the structural strength limit of the current velocity monitoring module 2. When the marine dynamic environment changes or the external force generated by interference between the marine ranching current velocity monitoring device and the mooring system exceeds the preset fracture threshold, the shear pin 4 fractures preferentially, causing the current velocity monitoring module 2 to automatically detach from the first flexible connecting component 3, effectively preventing the transmission of destructive stress to the current velocity monitoring module 2. This design, through a dual mechanism of flexible connection and overload protection, ensures the normal operation of the flow velocity monitoring function while avoiding the problem of entanglement and damage to the flow velocity monitoring module 2 caused by traditional fixed connection methods, thus significantly improving the reliability and economy of the device.

[0041] It should be noted that the technical mechanism of the damage to the current velocity monitoring module 2 caused by entanglement involved in this utility model is mainly reflected in the following three aspects: First, when the traditional fixed cable and the net cage mooring system become entangled, a rigid tensile force is formed. This force is directly transmitted through the cable to the housing of the precision acoustic Doppler current profiler 22 (ADCP) and its internal transducer array, causing deformation of the instrument structure or displacement of the core sensing element; Second, the continuous tension of the cable in the entangled state will cause mechanical friction between the ADCP and the seabed observation frame 21 under non-design conditions, leading to failure of the waterproof sealing structure and leakage; Third, when the aquaculture net cage is displaced by ocean currents, the entangled cable will force the ADCP to deviate from the vertical measurement posture, which not only affects the accuracy of the data, but also causes fatigue fracture of the instrument support structure due to long-term non-uniform stress. The shear pin 4 design of this utility model is specifically aimed at the above-mentioned mechanical transmission path, blocking the transmission of destructive stress through a controllable fracture node, fundamentally solving the structural reliability problem of traditional rigid connection methods under entanglement conditions.

[0042] It should be noted that the preset fracture threshold is set based on the extreme current velocity conditions of the marine ranch, or based on the rigid tensile force generated by the interference between the current velocity monitoring device and the mooring system. Specifically, the preset fracture threshold for fishing vessel towing scenarios is set at 1.5 tons (based on statistics of the average towing force of fishing vessels); when extreme weather such as typhoons causes severe sea conditions, the preset fracture threshold is set at 1 ton. See [link / reference] Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0043] The underwater acoustic beacon 5 is installed on the flow velocity monitoring module 2. The underwater acoustic beacon 5 is used to emit sound wave signals to locate the flow velocity monitoring module 2. By integrating an underwater acoustic beacon 5 onto the current velocity monitoring module 2, a positioning and protection system for the current velocity monitoring module 2 is constructed. The underwater acoustic beacon 5 can actively emit acoustic wave signals of a specific frequency. When the shear pin 4 breaks, causing the current velocity monitoring module 2 to separate from the surface buoy module 1, the location of the detached current velocity monitoring module 2 can be accurately located by receiving the acoustic wave signal. Combined with the original flexible connection and shear pin 4 protection structure, a triple protection mechanism of "anti-entanglement - overload protection - disconnection positioning" is formed. Among them, the first flexible connection component 3 reduces the risk of entanglement, the shear pin 4 enables controllable separation under external overload, and the underwater acoustic beacon 5 ensures the recoverability of the current velocity monitoring module 2 after separation. The synergistic effect of the three not only protects the high-value current velocity monitoring module 2 from damage, but also solves the problem of searching for the current velocity monitoring module 2 after it is detached, significantly improving the reliability and economy of the entire marine ranch current velocity monitoring device in complex marine environments.

[0044] See Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0045] A BeiDou positioning beacon 6 or a GPS positioning beacon is installed on the current velocity monitoring module 2 to provide its location information. By integrating the BeiDou positioning beacon 6 or GPS positioning beacon into the current velocity monitoring module 2, a multi-layered positioning protection system for the module is constructed. This beacon 6 or GPS positioning beacon can acquire and transmit the precise location information of the current velocity monitoring module 2 in real time. Even when the shear pin 4 breaks, causing the current velocity monitoring module 2 to separate, the beacon 6 or GPS positioning beacon can still continuously provide location data, ensuring real-time tracking after separation. In particular, the unique short message function of the BeiDou positioning beacon 6 allows for location information transmission in environments without communication networks, significantly improving the reliability and maintainability of the marine ranch current velocity monitoring device in deep-sea environments.

[0046] See Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0047] Acoustic signal receiver 7 is located at the bottom of the surface buoy module 1 and is positioned below the water surface. The acoustic signal receiver 7 is used to receive the acoustic wave signal from the underwater acoustic beacon 5 and convert the acoustic wave signal into an electrical signal.

[0048] A control module (not shown in the figure) is installed on the surface buoy module 1. The control module is electrically connected to the acoustic signal receiver 7, the Beidou positioning beacon 6 or GPS positioning beacon, and the shore-based main control platform (not shown in the figure). The control module transmits the electrical signals emitted by the acoustic signal receiver 7, the Beidou positioning beacon 6 or GPS positioning beacon to the shore-based main control platform. By setting an underwater acoustic beacon 5 on the current velocity monitoring module 2, configuring the acoustic signal receiver 7 on the surface buoy module 1, and the control module, a complete equipment monitoring and positioning system is constructed. The underwater acoustic beacon 5 emits acoustic signals, which are converted into electrical signals by the surface acoustic signal receiver 7. The control module then collaboratively processes the positioning data from the underwater acoustic beacon 5, the Beidou positioning beacon 6 or GPS positioning beacon, and transmits it to the shore-based main control platform via a communication link. This structural design provides dual positioning protection after the shear pin 4 breaks and the equipment separates. Acoustic positioning (underwater acoustic beacon 5 positioning) is achieved through this dual positioning protection. The acoustic positioning and satellite positioning (BeiDou positioning beacon 6 or GPS positioning beacon positioning) complement each other. The control module, as the information processing hub, realizes the fusion and transmission of multi-source data, forming a three-dimensional monitoring network of "acoustic positioning-satellite positioning-remote monitoring". This not only ensures the rapid positioning and recovery of the current velocity monitoring module 2 after separation, but also realizes the real-time remote transmission of monitoring data. It significantly improves the reliability and intelligence level of the entire marine ranch current velocity monitoring device in the complex environment of deep sea, and provides a comprehensive solution for marine ranch current velocity monitoring that integrates equipment protection, precise positioning and remote monitoring.

[0049] In one embodiment, the shear pin 4 has a fracture groove (not shown in the figure) in the middle. The fracture groove is arranged around the axial center line of the shear pin 4, so that when the shear pin 4 is subjected to radial external force, stress concentration can be formed at the fracture groove. This ensures that when the external force exceeds the preset fracture threshold, precise fracture occurs preferentially at the fracture groove position, so that the flow rate monitoring module 2 can disengage in time under the set external force conditions. At the same time, the circumferential continuous distribution characteristic of the fracture groove ensures the flatness of the fracture surface and the uniformity of the fracture force, improving the reliability of overload protection.

[0050] In one embodiment, the fracture groove has a V-shaped cross-section. By setting a V-shaped fracture groove in the middle of the shear pin 4, the stress concentration effect unique to the V-shaped structure is utilized to enable the shear pin 4 to form the maximum stress point at the tip of the fracture groove when subjected to radial external force. This structural feature ensures that the shear pin 4 will preferentially fracture precisely at the tip of the V-shaped fracture groove when the external force exceeds a preset threshold. The inclined surface design of the V-shaped cross-section not only optimizes the stress distribution and makes the fracture process more controllable, but also improves the fracture efficiency by increasing the initial crack propagation angle. Compared with ordinary grooves, the V-shaped fracture groove structure has a higher stress concentration coefficient with the same amount of material. This ensures the connection strength of the shear pin 4 under normal working conditions and enables rapid fracture protection under overload, significantly improving the overload protection accuracy and reliability of the shear pin 4. It provides a more accurate mechanical safety protection mechanism for the marine ranch flow velocity monitoring device, enabling the flow velocity monitoring module 2 to achieve rapid disengagement (fracture time less than 0.1 seconds) under set external force conditions, effectively avoiding the protection failure problem caused by the randomness of the fracture position of the traditional shear pin 4.

[0051] In one embodiment, the inclined angle of the fracture groove is 60°. By optimizing the inclined angle of the fracture groove of the shear pin 4 to 60°, this specific angle design ensures that the fracture groove has sufficient stress concentration effect while taking into account the overall structural strength of the shear pin 4. The V-shaped fracture groove structure formed by the 60° inclined angle can generate the best stress distribution state when the shear pin 4 is subjected to radial external force. This ensures that an effective stress concentration point is formed at the tip of the fracture groove to achieve precise fracture, while avoiding excessive weakening of material strength due to an excessively small angle or insufficient stress concentration due to an excessively large angle. This angle parameter has been mechanically optimized so that the shear pin 4 maintains sufficient connection strength under normal working conditions, and can achieve rapid and neat fracture at the fracture groove when the external force exceeds the preset threshold.

[0052] In one embodiment, the diameter of the shear pin 4 is d, and the depth of the fracture groove is b, where b = 0.3d. By precisely designing the fracture groove depth b of the shear pin 4 to be 0.3 times the diameter d, this proportional relationship has been mechanically optimized. This ensures both the structural strength of the shear pin 4 under normal working conditions and reliable fracture when the external force exceeds the threshold. The 0.3d depth design ensures that the fracture groove retains a sufficient effective load-bearing cross section, avoiding fracture failure due to being too shallow or affecting normal service strength due to being too deep.

[0053] In one embodiment, the shear pin 4 is a structure made of aluminum bronze alloy. By using aluminum bronze alloy to manufacture the shear pin 4, the excellent mechanical properties and corrosion resistance of this material ensure that the shear pin 4 has sufficient connection strength under normal working conditions, and can achieve precise fracture when the external force exceeds a preset threshold. The high strength of aluminum bronze alloy ensures that the shear pin 4 maintains stable mechanical properties in the marine environment for a long time, and its good fracture toughness makes the fracture process controllable and the fracture surface smooth. At the same time, the excellent seawater corrosion resistance of the material itself significantly extends the service life of the shear pin 4 in harsh marine environments.

[0054] See Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0055] The second flexible connecting component 8 has its first end connected to the flow velocity monitoring module 2 and its second end connected to the second end of the shear pin 4. By adding the second flexible connecting component 8, a double flexible connection structure is formed between the flow velocity monitoring module 2 and the shear pin 4. This design maintains the anti-entanglement advantage of the first flexible connecting component 3, while the second flexible connecting component 8 further buffers and disperses external force impacts. When encountering extreme sea conditions, the double flexible connection can effectively absorb and attenuate impact energy, reduce the instantaneous load on the shear pin 4, and cause it to break only under sustained overload, thereby avoiding false triggering. At the same time, the introduction of the second flexible connecting component 8 optimizes the force transmission path, making the shear pin 4 more evenly stressed and its breakage more controllable. Together with the first flexible connecting component 3, it forms a graded protection mechanism, which not only protects the high-value flow velocity monitoring module 2, but also improves the adaptability and reliability of the entire device in complex marine environments.

[0056] In one embodiment, both the first flexible connecting member 3 and the second flexible connecting member 8 can be cables or chains.

[0057] See Figure 1 In one embodiment, the flow rate monitoring module 2 includes:

[0058] Seabed observation frame 21, the seabed observation frame 21 is connected to the second end of the shear pin 4; and

[0059] An acoustic Doppler current profiler 22 is mounted on a seabed observation frame 21 and is used to monitor the current velocity in the environment where the marine ranch is located. By integrating the acoustic Doppler current profiler 22 (ADCP) into the seabed observation frame 21, a stable and reliable current velocity monitoring system is constructed. The seabed observation frame 21 acts as a rigid support platform directly connected to the shear pin 4, ensuring that the ADCP maintains its optimal measurement posture under normal operating conditions and guaranteeing the accuracy of the current velocity monitoring data.

[0060] In one embodiment, the seabed observation frame 21 is a structure made of 316 stainless steel, with an overall weight of 200kg, and can stand stably on the seabed. The seabed observation frame 21 has lifting rings installed on opposite sides, and each lifting ring is connected to the second flexible connecting component 8 to facilitate deployment and retrieval.

[0061] See Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0062] Solar panel 9 is installed on the water surface buoy module 1 and is electrically connected to the control module to provide power to the control module.

[0063] See Figure 1 In one embodiment, the marine ranch current velocity monitoring device further includes:

[0064] Solar-powered warning light 10 is installed on the surface buoy module 1 with an effective optical path of 2kN. The solar-powered warning light 10 is used to warn other vessels to take evasive action at night.

[0065] In one embodiment, the surface buoy module 1 includes an outer shell, a float, and a sealed chamber; the outer shell is made of polyethylene (800mm in diameter and 900mm in overall height), which is lighter than a metal shell of the same volume and has waterproof and corrosion-resistant capabilities; the float is located inside the outer shell and is made of EPS foam to ensure greater buoyancy and stability; the sealed chamber is located inside the float and is made of double-layer PVC material to ensure buoyancy and wind and wave resistance; the control module is located inside the sealed chamber.

[0066] The control module includes an industrial computer, a data transmission unit, a Beidou positioning beacon 6, and a temperature and humidity sensor to provide power, monitor the status of the surface buoy module 1, and transmit data.

[0067] A 100cm antenna is mounted on the surface buoy module 1 to ensure real-time data transmission at sea where signal conditions are poor.

[0068] The operation method of this marine ranch current velocity monitoring device is as follows:

[0069] The engineering vessel carried the marine ranch current velocity monitoring device to the designated location and used the first flexible connecting component 3 to deploy the current velocity measurement module to the seabed.

[0070] The ADCP on the flow velocity measurement module collects flow velocity / wave data → acoustically transmits it to the acoustic signal receiver 7 → the control module processes it;

[0071] Data is transmitted back to the shore-based main control platform in real time via the antenna on the surface buoy module 1;

[0072] When encountering abnormal external force, shear pin 4 breaks → dual modules separate → positioning and data preservation process is executed;

[0073] No trigger separation procedure → Construction vessel arrives at the site, arranges for divers to go down into the water along the first flexible connecting component 3 to the position of the current velocity monitoring module 2, and attaches a cable to the seabed observation frame 21 of the current velocity monitoring module 2. The personnel on the vessel retrieve the surface buoy module 1, bring the cable into the winch, and use the new cable to bring it into another winch, simultaneously recovering the current velocity monitoring module 2.

[0074] Trigger the separation procedure → Divers locate the current velocity monitoring module 2 using acoustic positioning and retrieve it by attaching a cable.

[0075] The triggering condition for the separation process is as follows:

[0076] When the external force is greater than or equal to the preset fracture threshold, the detachment is initiated: the threshold for the fishing boat towing scenario is set to 1.5 tons (based on the average towing force of the fishing boat).

[0077] When extreme weather such as typhoons causes severe sea conditions:

[0078] Surface buoy module 1: After detachment, it automatically activates the Beidou positioning beacon 6 to issue a deviation alarm and sends positioning data to the shore-based main control platform every 5 minutes for easy recovery.

[0079] Current velocity monitoring module 2: After failing to connect to the acoustic signal receiver 7 of the surface buoy module 1, it automatically enters a locked state and is powered by its built-in lithium battery (30-day battery life) to continuously store data in a waterproof memory. At the same time, it activates the underwater acoustic beacon 5 (2km effective range). When the staff arrives at the scene to handle the accident, based on the coordinates at the time of deployment, the ship and the acoustic signal receiver 7 will use fuzzy positioning to determine the approximate loss range of the current velocity monitoring module 2. Divers will then be arranged to search for and retrieve the current velocity monitoring module 2 within the limited range. The module will be attached to the seabed observation rack 21 and salvaged.

[0080] This design solves the problem of loss of flow rate monitoring module 2 caused by the device being dragged, moved, or entangled in the traditional solution, ensuring data continuity and equipment safety.
