Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, and in particular to a deep-sea intelligent aquaculture cage that can avoid typhoons. Background Technology

[0002] Modern deep-sea aquaculture primarily utilizes vessel-based and cage aquaculture technologies. This involves setting up massive cages in the ocean, mainly using aquaculture vessels or truss-type cages, and then cultivating marine life such as fish and shrimp within them. Existing deep-sea aquaculture equipment suffers from complex structures and poor economic efficiency, making it unsuitable for large-scale application. Reducing structural rigidity to lower costs, however, implies poor typhoon resistance, further limiting the development of deep-sea aquaculture. For example, Chinese patent number 2019205468533, a utility model patent for aquaculture cages, addresses this by reducing rigidity and cost. This patent improves the cages' resistance to wave fluctuations by incorporating flexible floating frames, netting, weights, and anchoring devices. While this does reduce the impact of wave fluctuations on the survival of aquatic products in deep-sea aquaculture, it fails to address the impact of typhoons. Therefore, proposing a new type of deep-sea aquaculture cage that can reduce costs and protect against typhoons is crucial. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deep-sea intelligent aquaculture cage that can avoid typhoons.

[0004] To achieve the above objectives, a deep-sea intelligent aquaculture cage designed to avoid typhoons includes a flexible floating frame device, a netting device, a weight device, an anchor chain device, and a typhoon avoidance system. The flexible floating frame device can float on the sea surface. The top of the netting device is connected to the flexible floating frame device and extends below the sea surface to form a space for aquaculture of marine organisms. Multiple sets of weight devices are provided and connected to the bottom of the netting device. At least one set of anchor chains is provided, with one end connected to the flexible floating frame device and the other end embedded in the seabed. The typhoon avoidance system controls the sinking or rising of the flexible floating frame device by injecting water or air. The flexible floating frame device includes multiple buoys and floating tubes. The buoys are provided with multiple buoy connection ends, and the floating tubes are provided with tube connection ends at both ends. The buoy connection ends and tube connection ends are hinged. Three adjacent buoys are connected by floating tubes to form a floating frame unit with an equilateral triangular structure. The flexible floating frame device includes multiple interconnected floating frame units.

[0005] The aquaculture cage provided by this utility model adopts a flexible floating frame device, which is connected by hinges between the floats and the float tubes. Each float has multiple connecting ends, and three adjacent floats are connected by float tubes to form an equilateral triangular floating frame unit, creating a stable triangular structure. The flexible floating frame device includes multiple interconnected floating frame units. This allows the flexible floating frame device to deform under the impact of waves, so that the local part of the flexible floating frame device fluctuates with the waves, while the whole is not significantly affected. Thus, the entire flexible floating frame device does not fluctuate with the waves, and consequently, it does not cause the entire net cage to sway. In other words, the swaying of the entire aquaculture cage is weak, reducing the impact on the survival of marine life inside the net cage. Furthermore, the deformation of the flexible floating frame device can also weaken the impact energy of the waves to a certain extent, thereby mitigating the problem of wave damage to the flexible floating frame device and the entire aquaculture cage, further improving the adaptability of the aquaculture cage.

[0006] Preferably, the flexible floating frame device comprises six floating frame units connected to form a regular hexagonal structure, eight floating frame units connected to form an isosceles trapezoidal structure, or multiple floating frame units connected to form other shapes.

[0007] By connecting the floating frame units with an equilateral triangular structure, various flexible floating frame devices can be constructed, all of which have good resistance to wave impact and strong structural stability.

[0008] Preferably, the float is provided with six connection ends.

[0009] Preferably, the netting device includes a netting body and a netting frame, the top end of the netting frame is connected to the flexible floating frame device, and the bottom end is connected to the weight device; the netting body surrounds the sides and bottom of the netting frame.

[0010] The netting device is placed below the sea surface. Specifically, the top of the netting device is connected to a flexible floating frame device, and the netting device is stretched out below the sea surface to form a space for aquaculture of marine life.

[0011] Preferably, the weight device comprises a plurality of solid columns and / or solid spheres made of reinforced concrete.

[0012] To prevent the netting from shifting with the waves, multiple sets of weights are installed at the bottom of the netting. These weights tighten the netting, stabilizing it and the entire aquaculture cage.

[0013] Preferably, the anchor chain device includes a chain, one end of which is connected to a buoy, and the other end is connected to a sinker or anchor that can be embedded in the seabed.

[0014] Anchor chains are installed to connect the flexible floating frame to prevent it from being carried away by the water flow.

[0015] Preferably, the typhoon avoidance system includes ventilation valves, and the float and the float pipe are each equipped with at least two ventilation valves.

[0016] Preferably, each end of the float tube is provided with a vent valve, and any vent valve of the float barrel and the float tube is connected to a flexible hose, which is connected to an input pipe, and the input pipe is connected to a switch valve.

[0017] The inlet pipe can be connected to the work vessel, and water or air can be injected into the buoy and buoy through the hose to test the sinking and floating of the flexible floating frame device, thereby avoiding typhoon damage.

[0018] Preferably, the typhoon avoidance system also includes a detachable net cover and a suspendable underwater offline camera system.

[0019] The cover net is used to cover the flexible floating frame device when it is lowered, to prevent aquatic products in the cage from escaping through the openings of the flexible floating frame device. The underwater offline camera system uses the flexible floating frame device to observe when it is lowered, to ensure that the speed and position of the descent meet the predetermined standards.

[0020] Preferably, the float or float tube is equipped with a buffer float.

[0021] The function of the buffer buoy is to provide a certain buoyancy to cushion the sinking of the flexible floating frame device, so as to prevent the flexible floating frame device from sinking too quickly.

[0022] Preferably, the typhoon avoidance system further includes an indicator buoy, and the input pipe is detachably connected to the indicator buoy.

[0023] The purpose of the marker float is to mark the input pipe, so that the input pipe can be located after the typhoon has passed.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The aquaculture cage provided by this utility model adopts a flexible floating frame device, which is connected by hinges between the floats and the float tubes. Each float has multiple connecting ends, and three adjacent floats are connected by float tubes to form an equilateral triangular floating frame unit, creating a stable triangular structure. The flexible floating frame device includes multiple interconnected floating frame units. This allows the flexible floating frame device to deform under the impact of waves, so that the local part of the flexible floating frame device fluctuates with the waves, while the whole is not significantly affected. Thus, the entire flexible floating frame device does not fluctuate with the waves, and consequently, it does not cause the entire net cage to sway. In other words, the swaying of the entire aquaculture cage is weak, reducing the impact on the survival of marine life inside the net cage. Furthermore, the deformation of the flexible floating frame device can also weaken the impact energy of the waves to a certain extent, thereby mitigating the problem of wave damage to the flexible floating frame device and the entire aquaculture cage, further improving the adaptability of the aquaculture cage. This cage structure is significantly simplified compared to truss cages, reducing construction materials and greatly lowering construction costs. By flooding the flexible floating frame before a typhoon arrives and inflating it after the typhoon, it effectively avoids the impact of typhoons on the cages and the resulting fish losses, unlike other cage systems.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0034] Example 1

[0035] This utility model provides a deep-sea intelligent aquaculture cage that can avoid typhoons, such as Figures 1-5 As shown, the system includes a flexible floating frame device 1, a netting device 2, a weight device 3, an anchor chain device 4, and a typhoon avoidance system. The flexible floating frame device 1 can float on the sea surface. The top of the netting device 2 is connected to the flexible floating frame device 1 and extends below the sea surface to form a space for aquaculture of marine life. Multiple sets of weight devices 3 are provided and connected to the bottom of the netting device 2. At least one set of anchor chain devices 4 is provided. One end of the anchor chain device 4 is connected to the flexible floating frame device 1, and the other end is embedded in the seabed. The typhoon avoidance system controls the sinking or rising of the flexible floating frame device by injecting water or air.

[0036] The flexible floating frame device 1 includes multiple floats 5 and float tubes 6. Each float 5 is provided with six bucket connection ends 51. Each float tube 6 is provided with a tube connection end 61 at both ends. The bucket connection ends 51 and the tube connection ends 61 are hinged together. Three adjacent floats 5 are connected by float tubes 6 to form a floating frame unit with an equilateral triangle structure. The flexible floating frame device 1 includes multiple interconnected floating frame units.

[0037] In one embodiment, the flexible floating platform device 1 includes six floating platform units, which are connected to form a regular hexagonal structure.

[0038] In one embodiment, the flexible floating frame device 1 includes eight floating frame units, which are connected to form an isosceles trapezoidal structure.

[0039] The netting device 2 includes a netting body and a netting frame. The top of the netting frame is connected to the flexible floating frame device 1, specifically, the top of the netting frame is connected to the float and / or float tube of the flexible floating frame device 1. The bottom of the netting frame is connected to the weight device 3, which includes multiple solid columns and / or solid spheres made of reinforced concrete, specifically, the solid columns or solid spheres are connected to the bottom of the netting frame. The netting body surrounds the sides and bottom of the netting frame. The netting body and netting frame can be implemented using any existing technology. The netting device 2 is set below the sea surface. Specifically, the top of the netting device 2 is connected to the flexible floating frame device 1, and the netting device 2 is spread out below the sea surface to form a space for aquaculture of marine organisms. To ensure that the netting device 2 does not move or deform with the waves, multiple sets of weight devices 3 are set at the bottom of the netting device 2. The weight devices 3 can tighten the netting device 2 to stabilize the netting device 2 and even the entire aquaculture cage.

[0040] The anchor chain device 4 includes a chain 41, one end of which is connected to the buoy 5, and the other end is connected to a sinker or anchor that can be embedded in the seabed. The flexible floating frame device 1 can float on the sea surface, and multiple sets of anchoring devices 4 are set around the flexible floating frame device 1. The flexible floating frame device 1 is pulled from various directions by the anchoring devices 4 to ensure that the flexible floating frame device 1 does not move too much under the impact of sea waves.

[0041] Under the impact of ocean waves, the flexible floating frame device 1 can deform because the floating barrel 5 and the floating pipe 6 are hinged through the barrel connection end and the pipe connection end. The flexible floating frame device 1 is composed of multiple equilateral triangular floating frame units, which can maintain the basic frame structure of the whole. This means that while the local part of the flexible floating frame device 1 fluctuates with the ocean waves, the whole is not greatly affected. Thus, the entire flexible floating frame device 1 does not fluctuate with the ocean waves, and consequently, it does not cause the entire netting device 2 to sway. That is, the swaying of the entire aquaculture net cage is weak, reducing the impact on the survival of marine life inside the netting device 2. Furthermore, the deformation of the flexible floating frame device 1 can also weaken the impact energy of the ocean waves to a certain extent, thereby mitigating the problem of ocean waves damaging the flexible floating frame device 1 and the entire aquaculture net cage, and further improving the adaptability of the aquaculture net cage.

[0042] The typhoon avoidance system includes ventilation valves 7. The float 5 is equipped with at least two ventilation valves 7, and each end of the float pipe 6 has a ventilation valve 7. Any ventilation valve 7 of the float 5 and float pipe 6 is connected to a flexible hose (not shown in the figure). The flexible hose is connected to an input pipe (not shown in the figure), and the input pipe is connected to a switch valve (not shown in the figure). The typhoon avoidance system also includes a detachable cover net (not shown in the figure) and a suspendable underwater offline camera system (not shown in the figure). The float 5 or float pipe 6 is equipped with a buffer buoy (not shown in the figure). The typhoon avoidance system also includes a marker buoy (not shown in the figure), and the input pipe is detachably connected to the marker buoy.

[0043] The typhoon avoidance system operates as follows:

[0044] Super 12 typhoon flooding and sinking: A cover net is added to the flexible floating frame device 1 to prevent farmed aquatic products from escaping. The cover net can be implemented using any existing technology. An underwater offline camera system is suspended to observe the underwater situation when the flexible floating frame device 1 sinks. The underwater offline camera system can be implemented using any existing technology. Each ventilation valve 7 is connected in series and parallel to the input pipe through a hose. The input pipe is fixed to the workboat. Open the switch valve, lower each hose to hang naturally to a depth of more than 2 meters underwater, open each ventilation valve 7, ensure that there are no personnel in the net cage, and keep the workboat 10 meters away from the net cage. Beyond 0 meters, fill the inlet pipe of the confluence with water and observe the sinking situation; the flexible floating frame device 1 is equipped with a buffer ball to prevent the net cage floating frame from sinking accidentally (the buffer ball can also be removed by setting a weight to sink to the seabed to achieve self-balancing). The length of the mooring rope is slightly greater than the sinking depth (the sinking depth is the water depth minus the net depth). After stabilization, close all ventilation valves 7, retract and tie the hose so that the remaining length is about 20 meters, tie the inlet pipe to the marker buoy and close the switch valve. At this time, the moored buffer ball can be removed. In one embodiment, a buffer buoy can also be used instead of the buffer ball.

[0045] After the typhoon, the workboat moves to the location of the net cage, finds the marked buoy, unfolds the hoses, opens all the ventilation valves 7, connects the input pipe to the workboat's air compressor, pumps in high-pressure air, and after the flexible floating frame device 1 floats to the water surface, the ventilation valves 7 of each float 5 or float pipe 6 stably discharge the air bubbles, then stop pumping air, close all the ventilation valves 7, hang each hose back to the predetermined position (which can be hung on the flexible floating frame device), remove the cover net, and the floating is completed.

[0046] Example 2

[0047] This utility model provides an operation method for a deep-sea intelligent aquaculture cage that can avoid typhoons, such as... Figures 1-5 As shown, the following methods are included:

[0048] I. Assembly: Select a relatively calm water area near the port or inland river leading to the sea for assembly operations. First, assemble the flexible floating frame device 1 on the shore (ventilation valves 7 need to be reserved symmetrically in the buoy 5 or floating pipe 6). The buoy 5 and floating pipe 6 are connected by hinges. A crane or mobile lifting equipment is used to lift the assembled basic frame of the flexible floating frame device 1 into the water. Assemble the remaining flexible floating frame device 1 parts one by one on the water. Two small engineering boats equipped with lifting equipment are used to assist. After the flexible floating frame device 1 is assembled, moor it on the shore.

[0049] 2. Hanging nets and splicing netting: The netting device 2 is lowered into the water and moved to the lower part of the flexible floating frame device 1 by the engineering vessel and installed and fixed. The weight device 3 is then suspended.

[0050] 3. Towing: The three vertices of the flexible floating frame device 1 are connected to the tugboats via mooring cables. Two tugboats will tow the cages, maintaining a safe distance of 50-100m between the cages and the tugboats, with a speed not exceeding 3 knots.

[0051] 4. Deployment: Upon arrival at the deployment location, the engineering vessel will place one, three, six or more gravity anchors, and finally attach the friction chain connecting the nylon cable to the buoy. After anchoring, the tugboat will leave, completing the deployment.

[0052] V. Flooding and Sinking to Avoid Typhoons (Category 12 and Above): Install a netting cover and suspend an underwater offline camera system; connect each ventilation valve 7 in series and parallel to the water injection connection pipe (i.e., the input pipe) via flexible hoses; install a valve at the end of the water injection connection pipe and secure it to the workboat; lower the hoses connecting each float 5 or float pipe 6 to a depth of more than 2 meters underwater, and open each ventilation valve 7; ensure there are no personnel in the net cage, and the workboat is more than 100 meters away from the net cage; open the valve on the water injection connection pipe of the confluence hose, observe the sinking situation, and moor the buffer floats or buffer balls to prevent the flexible floating frame device of the net cage from sinking unexpectedly (or the floats or balls can be removed by sinking to the seabed with a weight). The length of the mooring rope should be slightly greater than the sinking depth (water depth - net depth). After stabilization, close the ventilation valves 7; retract and tie the flexible hoses, leaving approximately 20 meters remaining, and attach them to the marker buoy; at this point, the buffer floats or buffer balls can be removed.

[0053] VI. Air Injection and Ascent After Typhoon: The work vessel sails to the location of the net cage, locates the marked buoy of the mooring hose, and unfolds the hose; the hose is connected to the work vessel's air compressor, and high-pressure air is pumped in; after the flexible floating frame device 1 rises, and each float 5 or float pipe 6 stably discharges air bubbles, the air pumping is stopped, and the ventilation valve 7 is closed; each hose is hung back in its original position; the cover net is removed, and the ascent is completed.

[0054] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
