At present, large-scale deep-sea fishery farming cage platforms have been used in offshore fishery farming and have shown good economic and social benefits. However, due to the harsh wind and wave conditions and frequent typhoons in the offshore waters, the cage platform needs to be sunk to the seabed by sitting on the bottom, and the cage platform needs to be fixed to the seabed through positioning and anchoring technology to avoid the typhoon and wave-affected areas and ensure the safety of the cage structure.

The anchor chains and gripping anchors used in this technology consume a large amount of steel, have a high construction cost, and the cages have poor bottom stability, which makes it easy for the cages to shift, making it difficult to meet the requirements for fixing the aquaculture cage platforms on the seabed.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0035] At present, the conventional positioning and mooring solution for deep-sea aquaculture cage platforms is to use a positioning and mooring system consisting of anchor chains and gripping anchors (such as Guangdong's "Haiwei" series cages). The anchor chains and gripping anchors used in this technology consume a large amount of steel, have a high construction cost, and the cages have poor bottom stability, which makes it easy for the cages to shift, making it difficult to meet the requirements for fixing the aquaculture cage platforms on the seabed.

[0036] In order to solve the above-mentioned problems existing in the existing cage positioning and mooring systems, the utility model proposes a cage suction pile column assembly, which integrates the aquaculture cage platform buoy and anchor piles into one, eliminates conventional positioning and mooring systems such as anchor chains and gripping anchors, and realizes autonomous pile sinking, bottom seating, and floating operations of the cage through corresponding drainage and water injection operations.

[0037] See also Figure 1 and Figure 2 In one embodiment of the utility model, the net cage suction pile column assembly includes a column 1, a suction pile box 2 and a suction device 3; the suction pile box 2 is arranged at the lower end of the column 1; a ballast chamber is arranged in the suction pile box 2; the suction device 3 is arranged on the suction pile box 2, and the suction device 3 is connected to the ballast chamber; the suction device 3 is used to suck external water into the ballast chamber, and the suction device 3 is used to discharge the water in the ballast chamber to the outside.

[0038] In this embodiment, a plurality of cage suction pile components together form a cage frame, and the net is fixed on the cage frame to form a complete aquaculture cage platform. The suction device 3 can be any suction pump suitable for use in a deep sea environment, which is not limited here.

[0039] Based on the improvement of the above-mentioned cage suction pile assembly, when the aquaculture cage platform is built and towed to the target sea area, the external seawater can be sucked into the ballast chamber through the suction device 3, so that the weight of the aquaculture cage platform gradually increases, so that the aquaculture cage platform can overcome the buoyancy and sink; when the aquaculture cage platform sinks to the seabed, the suction operation of the suction device 3 can generate a pressure difference on the surface of the suction pile box 2, which helps the suction pile box 2 to penetrate the preset depth position below the seabed at a certain rate under the action of external negative pressure, so that the aquaculture cage platform can be stably seated on the bottom, avoiding the aquaculture cage platform from deflecting on the seabed surface, so that the aquaculture cage platform can operate safely under relatively severe sea conditions. Among them, when the soil of the seabed is relatively soft, the depth of the suction pile box 2 penetrating into the seabed can reach 1 to 2 meters.

[0040] When the aquaculture cage platform needs to float to the sea surface for towing and other operations, it only needs to drain the seawater in the ballast chamber through the suction device 3 to make the overall mass of the aquaculture cage platform smaller than the buoyancy it receives, so that the aquaculture cage platform can float.

[0041] It can be seen that the cage suction pile assembly provided in this embodiment has the following advantages:

[0042] 1. Conventional positioning and mooring systems such as anchor chains and grab anchors are eliminated, which reduces the amount of steel used in the aquaculture cage platform. There is no need to lay out and install anchor chains and grab anchors, which greatly reduces the construction cost of the aquaculture cage platform and is conducive to large-scale promotion of construction and aquaculture use.

[0043] Second, the sinking and floating system and the suction pile system are integrated and applied to the deep-sea aquaculture cage platform. The vacuum negative pressure and water injection and drainage functions are realized through the cooperation of the suction device 3 and the ballast chamber, so that the aquaculture cage platform only needs to be positioned in the installation sea area by a tugboat, and a series of operations of the caisson pile anchor can be completed by itself. It has a wide range of applications and can be used in sea areas with a water depth of 10 to 28 meters and shallow geological layers on the seabed without large pebbles;

[0044] 3. During the bottoming process of the cage, the vacuum negative pressure suction of the suction pile box 2, the vertical friction force of the soil layer and the lateral squeezing force can provide an anchoring force far greater than that provided by conventional anchoring forms, ensuring that the aquaculture cage platform can be safely operated in the future after the bottoming;

[0045] Fourth, the reverse punching of the aquaculture cage platform can be achieved through the suction device 3, so as to realize the floating, towing, maintenance and repositioning installation of the aquaculture cage platform;

[0046] 5. Through the separation design of the suction pile box 2, the floating box and the anchor pile of the aquaculture cage platform are integrated into one; through the corresponding drainage and water injection operations, the buoyancy required for the aquaculture cage platform to be towed can be provided, and the initial pressure can be provided when the cage sinks and the suction pile box 2 enters the mud; without the need for ROV (Remotely Operated Vehicle) and auxiliary support vessels, the towing, bottoming, pile sinking, floating, maintenance and repositioning and installation of the aquaculture cage platform can be completed by using the tugboat and the system provided by the aquaculture cage platform.

[0047] Optionally, refer to Figure 1 and Figure 2 , the surface of the suction pile box 2 is provided with bite ribs 21. By providing the bite ribs 21, the pull-out resistance and friction force of the suction pile box 2 after entering the mud can be increased, thereby improving the bottom stability of the cage. According to different seabed geology, muddy soil and other conditions, the number and size of the bite ribs 21 can be designed and optimized accordingly; preferably, the number of the bite ribs 21 is multiple, and the multiple bite ribs 21 are arranged at intervals along the circumference of the suction pile box 2, so that the pull-out resistance and friction force of each position on the suction pile box 2 after entering the mud can be evenly improved.

[0048] Optionally, refer to Figure 1 and Figure 2 The net cage suction pile assembly also includes a control module 5 and a pressure regulating module 6; the pressure regulating module 6 is electrically connected to the control module 5 and the suction device 3; the pressure regulating module 6 is used to increase or decrease the suction pressure of the suction device 3 according to the boost signal or buck signal output by the control module 5.

[0049] By adjusting the suction pump pressure and controlling the penetration rate of the four piles of the aquaculture platform, the suction piles are penetrated to the designed depth below the seabed, ensuring that the cage sits stably on the bottom as a whole and operates safely under the set sea conditions.

[0050] Specifically, the control module 5 can adopt an MCU (Microcontroller Unit) with basic functions such as storage, program call, data comparison and judgment, signal input and output, etc. The suction device 3 can adopt any suction pump with suction pressure regulation function; the pressure regulating module 6 can convert the boost signal and the pressure reducing signal output by the control module 5 into an electrical signal that can be read by the suction device 3, so as to control the current suction pressure of the suction device 3.

[0051] Based on the above settings, the current suction pressure of the suction device 3 can be adjusted accordingly according to factors such as seabed geology, mud and soil, ocean current conditions, and the need for the cage to sit on the bottom; when the suction pressure increases, the movement rate of the cage suction pile column assembly can be increased, thereby increasing the pile sinking rate and floating rate of the aquaculture cage platform; when the suction pressure decreases, the movement rate of the cage suction pile column assembly can be reduced, thereby reducing the pile sinking rate and floating rate of the aquaculture cage platform.

[0052] In an application example, when the aquaculture cage platform sinks to a certain height from the seabed at a relatively stable rate, a larger negative pressure force can be applied to the suction pile box 2 by increasing the suction pressure of the suction device 3, so that the suction pile box 2 can penetrate the seabed at an extremely fast rate when approaching the seabed, thereby increasing the penetration depth, obtaining a greater anchoring force, and further improving the bottom stability of the aquaculture cage platform.

[0053] Optionally, refer to Figure 1 and Figure 2 The net cage suction pile assembly also includes a wireless communication module 7; the wireless communication module 7 is electrically connected to the control module 5; the wireless communication module 7 is used to convert the received external wireless input signal into a control electrical signal and output it to the control module 5; the control module 5 is used to output a boost signal or a buck signal according to the control electrical signal.

[0054] Specifically, the wireless communication module 7 may include wireless communication devices such as WIFI and Bluetooth; the wireless communication module 7 may be used to receive external wireless input signals sent by operators on shore or on ships through signal output devices, and control the suction device 3 to perform boosting or reducing operations in real time through signal transmission between the control module 5 and the voltage regulating module 6. In this way, the suction device 3 is controlled based on external instructions, and the operator can control the suction device 3 to increase or reduce the suction pressure in real time by remote control without being restricted by distance, thereby improving the convenience of operation and enabling the movement rate of the aquaculture cage platform to better adapt to the current situation.

[0055] Optionally, refer to Figure 1 and Figure 2 The net box suction pile column assembly also includes a rate detection module 8; the rate detection module 8 is electrically connected to the control module 5; the rate detection module 8 is used to obtain the current rate data of the suction pile box 2 and output it to the control module 5;

[0056] The control module 5 pre-stores a rate threshold condition; when the current rate data received by the control module 5 meets the rate threshold condition, the control module 5 is used to output a corresponding boost signal or a buck signal.

[0057] In this embodiment, the rate threshold condition can be used to limit the normal movement state of the net cage suction pile column assembly. For example, it can be set that when the current sinking rate of the suction pile box 2 exceeds a maximum critical rate, the control module 5 outputs a pressure reduction signal to the pressure regulating module 6 to reduce the current suction pressure of the suction device 3 and reduce the sinking rate of the net cage suction pile column assembly; it can also be set that when the current sinking rate of the suction pile box 2 is less than a minimum critical rate, the control module 5 outputs a pressure increase signal to the pressure regulating module 6 to increase the current suction pressure of the suction device 3 and increase the sinking rate of the net cage suction pile column assembly.

[0058] Based on the above settings, not only can the movement speed of the aquaculture cage platform be fed back to the operator in real time, but the autonomous speed adjustment of the aquaculture cage platform can also be achieved to a certain extent, avoiding the problem of the aquaculture cage platform moving too fast or too slow. Therefore, operations such as sinking piles, sitting on the bottom, and floating can be completed more accurately according to the preset plan, and the intelligence level of the equipment can also be improved.

[0059] Optionally, refer to Figure 1 and Figure 2 The net box suction pile column assembly also includes a depth detection module 9; the depth detection module 9 is electrically connected to the control module 5; the depth detection module 9 is used to obtain the current depth data of the suction pile box 2 and output it to the control module 5;

[0060] The control module 5 pre-stores a depth-rate comparison table; the control module 5 is used to retrieve the corresponding target rate from the depth-rate comparison table according to the received current depth data, and replace the critical rate in the rate threshold condition with the target rate.

[0061] When the aquaculture cage platform is at different depths underwater, its requirements for the critical rate are also different; for example, when the aquaculture cage platform is closer to the seabed, the suction pile box 2 needs to penetrate the seabed at a faster rate to achieve the bottoming operation of the aquaculture cage platform. At this time, the maximum critical rate can be set to a larger value to avoid the forced pressure reduction operation due to the current rate of the suction pile box 2 exceeding the maximum critical rate. Based on the above considerations, this embodiment associates the current depth data of the suction pile box 2 with the rate data, so that the control module 5 can adjust the rate threshold condition in real time according to the current depth condition, thereby realizing the autonomous rate adjustment of the aquaculture cage platform at different depths, avoiding the problem of the aquaculture cage platform moving too fast or too slow at different depths, further improving the accuracy of the aquaculture cage platform in autonomously completing operations such as pile sinking, bottoming, and floating, and further improving the intelligence of the equipment.

[0062] Optionally, refer to Figure 1 and Figure 2The control module 5, the voltage regulating module 6, the wireless communication module 7, the speed detection module 8, and the depth detection module 9 are integrated in the central control box 4; the central control box 4 is detachably connected to the upper end of the column 1.

[0063] In this embodiment, each functional module adopts a container-type integrated system configuration to meet the needs of rapid disassembly and assembly. The central control box 4 can be replaced at any time and used for operations such as bottoming, piling, floating, maintenance, and repositioning and installation of other aquaculture cage platforms, thereby improving the reuse rate of each functional module and reducing product costs.

[0064] See also Figure 1 The utility model also proposes a breeding cage, which includes a net (not shown in the figure) and a cage suction pile assembly in any of the above embodiments; a plurality of cage suction pile assemblies are arranged at intervals along the circumferential direction to form a cage frame, and the net is fixed on the cage frame.

[0065] The aquaculture cage provided in this embodiment can specifically be a large-scale aquaculture cage platform for deep sea. Since the aquaculture cage adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, that is, the aquaculture cage platform buoy and anchor piles are integrated into one, and conventional positioning and mooring systems such as anchor chains and gripping anchors are eliminated. Through corresponding drainage and water injection operations, the cage can achieve autonomous pile sinking, bottom sitting, floating and other operations.

[0066] In actual applications, even if the preset parameters of the suction pile column assembly of each cage in the aquaculture cage (including the suction pressure of the suction device 3, the amount of water in the ballast chamber, etc.) are completely consistent, under the influence of factors such as complex ocean current conditions, there will still be a problem of inconsistent actual movement rates of the suction pile column assemblies of each cage. When the actual movement rates of the suction pile column assemblies of each cage differ greatly, it may cause a large deflection of the aquaculture cage, thereby adversely affecting the normal movement process of the aquaculture cage.

[0067] Based on the above problems, this embodiment is proposed accordingly. Figure 1 The breeding cage also includes a height detection module (not shown in the figure) and a prompt device (not shown in the figure); the height detection module is electrically connected to the prompt device; the height detection module is used to obtain the current height data of the suction pile box 2 in each cage suction pile column assembly, and the height detection module is used to output an abnormal signal to the prompt device when the maximum difference between multiple current height data exceeds the critical height difference threshold, so as to trigger the prompt device to perform an alarm operation.

[0068] By setting up a height detection module, when the actual movement rates of the suction pile components of each cage differ greatly and cause the aquaculture cage to be at risk of deflection, an alarm message can be issued through the prompt device to inform the operator to intervene in time, thereby improving the stability and reliability of the aquaculture cage during autonomous execution of operations such as sinking piles, sitting on the bottom, and floating.

[0069] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
