Description

Technical Field

[0001] This invention belongs to the field of aquaculture cage technology, and particularly relates to a submersible, floating deep-sea truss aquaculture cage. Background Technology

[0002] In recent years, due to high-density nearshore aquaculture, excessive wastewater discharge, and long-term overfishing, my country's nearshore fishery resources have fallen into a serious depletion crisis. Deep-sea aquaculture, as a new type of marine aquaculture, has presented another possibility for the development of the marine aquaculture economy. However, the vast and rich deep sea also means that the fishing grounds will be in a harsh marine environment, and the following requirements are placed on the aquaculture cages: (1) Seawater corrosion resistance: The cage material should have the property of resisting seawater corrosion and be able to be used in seawater for a long time without corrosion; (2) Sturdy structure: The cage needs to be able to withstand the impact of large waves and ocean currents, so the structure must be sturdy and stable; (3) Water permeability: The cage should have a certain water permeability to maintain the circulation of seawater and avoid the formation of dead water areas; (4) Convenient cleaning and maintenance: The design should take into account the convenience of cleaning and maintenance of the cage to ensure the cleanliness and hygiene of the aquaculture environment; (5) Escape prevention measures: There should be an escape prevention design to prevent farmed animals from escaping into the wild environment.

[0003] In existing nearshore aquaculture, small and medium-sized net cages are mostly used for aquaculture operations. These small and medium-sized net cages have relatively simple structures and suffer from the disadvantage of small effective culture volume and small culture units. If small and medium-sized net cages are used for deep-sea aquaculture, their light weight and weak wind and wave resistance make them difficult to adapt to the aquaculture requirements of deep-sea areas with high waves and strong winds. There are also aquaculture net cages with all-steel main trusses, which are not only expensive but also susceptible to marine corrosion, resulting in loss of structural performance. This makes steel net cages difficult to operate and has high maintenance costs. There is also a deep-sea net cage aquaculture device and method, such as the one with patent number 201710328536.X, which achieves submersion and buoyancy by inflating and deflating the columns. When the inflation speed of different columns is different, the buoyancy of the net cage is asymmetrical, which can easily lead to imbalance or even capsizing.

[0004] In addition, the above-mentioned small and medium-sized net cages and all-steel net cages with main trusses are affected by the need to maintain balance and control the synchronicity of drainage in various parts during the process of placing them into the sea or taking them out of the sea, or the process of floating and sinking the net cages. This greatly affects the overall floating and sinking efficiency of the net cages. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a submersible, floating deep-sea truss aquaculture cage.

[0006] The technical solution of this invention is as follows:

[0007] This invention discloses a submersible, floating deep-sea truss aquaculture cage, comprising:

[0008] A controllable buoyancy self-circulation system includes a shell, an oil pump, and a bidirectional jack. The oil pump is fixedly installed inside the shell, and the bidirectional jack is movably installed inside the shell. The oil pump drives and connects to the bidirectional jack. The shell is provided with multiple drain outlets, which are distributed on both sides of the bidirectional jack.

[0009] A submersible floating cage system includes several cables, several columns, several hollow tubes, a float ring, and supporting components. The float ring serves as the bottom of the submersible floating cage system. The hollow tubes and columns are arranged along the periphery of the float ring, and the hollow tubes and columns combine to form the frame of the submersible floating cage system. The supporting components are arranged between the float ring and the hollow tubes, and between the columns and the hollow tubes. One end of each cable is connected to a column, and the other end of the cable is connected to the shell of the controllable buoyancy self-circulation system. Several drainage outlets are provided on some of the columns.

[0010] An anchor cable system, which is connected to a portion of the column.

[0011] Furthermore, the housing includes a low-resistance top cover, a sealing area, and a water-permeable area. The low-resistance top cover is located above the sealing area and is connected to the cable. The oil pump is located in the sealing area, and the bidirectional jack is located in the water-permeable area. One drain outlet is located at the high water level of the water-permeable area, and the other drain outlet is located at the low water level of the water-permeable area.

[0012] Furthermore, the bidirectional jack includes an upper piston, a lower piston, and a connecting pipe. The housing is also provided with several control switches. The connecting pipe is located between the upper piston and the lower piston. The oil pump is connected to the connecting pipe. The control switches are located within the moving space of the upper piston and are located below the drain outlet on the same side.

[0013] Furthermore, the submersible cage system also includes a floating corridor assembly, which includes a surrounding corridor and three branch corridors. The surrounding corridor is located on the top surface of the entire submersible cage system and is fixedly connected to the top of the column. One end of each branch corridor is connected to the surrounding corridor, and the other end of each branch corridor is fixedly connected to a controllable buoyancy self-circulation system. The three branch corridors are distributed at intervals around the controllable buoyancy self-circulation system. Both the surrounding corridor and the three branch corridors include guardrails and several crossbars, with the guardrails located on both sides of the crossbars.

[0014] Furthermore, the hollow tube includes a top annular hollow tube and a bottom annular hollow tube, the bottom annular hollow tube being disposed on the outer ring of the float, and the surrounding corridor being disposed above the top annular hollow tube.

[0015] Furthermore, a connecting rod is directly inserted through the bottom annular hollow tube and the float, and one end of the connecting rod is connected to the shell of the controllable buoyancy self-circulation system.

[0016] Furthermore, the support includes a horizontal support, a mesh support, and an inclined support. The horizontal support passes through the column, the mesh support is disposed between the horizontal support, the mesh support is also disposed between the bottom annular hollow tube and the float and between the float and the shell, and the inclined support is disposed between the horizontal support and the column.

[0017] Furthermore, the anchoring system includes a hemp rope, a chain, and an anchor hook. The hemp rope is mounted on the post, one end of the chain is connected to the hemp rope, and the anchor hook is mounted on the other end of the chain.

[0018] Furthermore, the column, the hollow tube, the guardrail, and the connecting rod are all made of high-density polyethylene, and the cable is made of fiber-reinforced composite material.

[0019] Furthermore, the controllable buoyancy self-circulation system also includes a first connecting pipe and a second connecting pipe, the first connecting pipe being located between the oil pump and the bidirectional jack, and the second connecting pipe extending from the oil pump to the outer wall of the housing.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) A controllable buoyancy self-circulation system was designed. By adjusting the buoyancy of the net cage, firstly, the balance of the net cage and the synchronicity of drainage of each part are maintained, while improving the overall floating efficiency of the net cage; secondly, the position of the net cage in the water can be controlled so that it can adapt to different water depths; this can better control the water quality, keep the water clean and stable, and provide a good growth environment; then, deep-sea aquaculture net cages are usually affected by the wind and waves of the marine environment. By adjusting the buoyancy, the net cage can be kept in a stable position, reducing the impact of wind and waves and reducing the risk of net cage damage and fish escape; finally, controlling the floating allows for convenient adjustment of the position of the net cage, reducing the workload and risk of manual operation.

[0022] (2) A submersible floating cage system was designed. The cable is connected to the controllable buoyancy self-circulation system, so that the cage has the function of rapid floating. The hollow tube, float ring and column with drainage outlet can reduce the weight of the aquaculture cage and allow the liquid to flow through the drainage outlet, which assists the cage to float and ensures the safety of the cage during the floating process. In addition, the overall structural design makes the cage resistant to seawater corrosion, the structure is strong and can withstand the impact of large waves and ocean currents, and has a certain water permeability to maintain the circulation of seawater. The cage is also convenient to clean and maintain, and can also prevent farmed animals from escaping to the wild environment. Attached Figure Description

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Here, A and B can be singular or plural, respectively.

[0034] In addition to designing aquaculture cages that meet the requirements of deep-sea aquaculture, it is also necessary to address the issues of low buoyancy and sinking efficiency and imbalance between submersion and buoyancy. Please refer to [reference needed]. Figures 1-4 This invention provides a submersible, floating deep-sea truss aquaculture cage, comprising:

[0035] A controllable buoyancy self-circulation system 1 includes a housing 11, an oil pump 12, and a bidirectional jack 13. The oil pump 12 is fixedly installed inside the housing 11, and the bidirectional jack 13 is movably installed inside the housing 11. The oil pump 12 drives and connects to the bidirectional jack 13. The housing 11 has four drain ports 4, which are evenly spaced around the outer wall of the housing. The drain ports 4 are distributed on both sides of the bidirectional jack 13. (Refer to...) Figure 2 The two-way jack 13 is provided with two drain outlets 4 on each side. The drain outlets 4 can be closed or opened by the oil pump 12 to control the liquid to enter or exit the shell 11, increase or decrease the weight of the aquaculture net cage to control its floating and sinking, thereby effectively improving the floating and sinking efficiency of the net cage.

[0036] It is worth noting that the drainage outlets 4 on the shell 1 can be set to six or eight, with three or four evenly distributed on one side, and the drainage outlets 4 on the same side are on the same horizontal line, ensuring that the bidirectional jack 13 can block the drainage outlets 4; the actual size of the cage of the present invention is a radius of more than 10 meters, and the volume of the above-mentioned controllable buoyancy self-circulation system is also relatively large, so the bidirectional jack used is not an ordinary jack, but has a sufficiently long travel.

[0037] The specific process is as follows: During the process of placing the aquaculture cage into the sea or sinking the aquaculture cage, the liquid is controlled to enter the shell 11 through the four drain ports 4 to increase the weight of the aquaculture cage, thereby accelerating the sinking speed of the aquaculture cage. During the process of taking the aquaculture cage out of the sea or floating the aquaculture cage, the liquid is controlled to be discharged through the four drain ports 4 inside the shell 11 to reduce the weight of the aquaculture cage, thereby accelerating the lifting speed of the aquaculture cage. The whole process achieves rapid floating and submersion of the aquaculture cage. In addition, the bidirectional working process of the bidirectional jack 13 is uniform, so there will be no problem of asymmetrical buoyancy caused by different speeds and amounts of liquid entering the shell.

[0038] By improving buoyancy efficiency, the position of the net cage in the water can be controlled by adjusting its buoyancy, allowing it to adapt to different water depths. This enables better control of water quality, maintaining water cleanliness and stability, and providing a favorable growth environment. Furthermore, deep-sea aquaculture net cages are often affected by wind and waves in the marine environment. Adjusting buoyancy can keep the net cage in a stable position, reducing the impact of wind and waves and lowering the risk of net cage damage and fish escape. Finally, by using oil pump 12 to drive and control buoyancy, the position of the net cage can be easily adjusted, reducing the workload and risks of manual operation.

[0039] A submersible floating cage system 2 is mainly used to support aquaculture organisms and is structurally adjustable in conjunction with a controllable buoyancy self-circulation system 1. The submersible floating cage system 2 includes several cables 21, several columns 22, several hollow tubes 23, a float ring 24, and support members 25. The float ring 24 serves as the bottom of the submersible floating cage system 2, increasing buoyancy for the entire cage. The hollow tubes 23 and the columns 22 are arranged around the periphery of the float ring 24, and the hollow tubes 23 and the columns 22 combine to form the frame of the submersible floating cage system 2. The support members 25 are located on... The float 24 and the hollow tube 23 are located between the support 25 and the column 22. One end of the cable 21 is connected to the column 22, and the other end of the cable 21 is connected to the shell 11 of the controllable buoyancy self-circulation system 1. The submersible net cage system 2 and the controllable buoyancy self-circulation system 1 are connected as one unit through the cable 21. Furthermore, some of the columns 22 are provided with several drainage ports 4, which means that the submersible net cage system 2 itself also has the function of accelerating the inflow and outflow of liquid, and the design of the drainage ports 4 can reduce the weight of the submersible net cage system 2.

[0040] Anchor cable system 3 is connected to part of the columns 22. It is generally controlled by a ship crane to penetrate and fix it to the seabed, thereby fixing the entire net cage, making the net cage more stable during the lifting and lowering process, and improving the stability of the net cage in a static environment.

[0041] Furthermore, the housing 11 includes a low-resistance top cover 111, a sealing area 112, and a water-permeable area 113. The low-resistance top cover 111 is located above the sealing area 112 and is connected to the cable 21. Figure 1 and Figure 2 The diameter of the low-resistance top cover 111 is smaller than the diameter of the shell 11. The low-resistance top cover 111 is made of HDPE material and is hollow inside, so that the low-resistance top cover 111 can assist the floating of the net cage. The oil pump 12 is located in the sealing area 112, and the bidirectional jack 13 is located in the permeable area 113. One side drain outlet 4 is located at the high water level of the permeable area 113, and the other side drain outlet 4 is located at the low water level of the permeable area 113.

[0042] Furthermore, the bidirectional jack 13 includes an upper piston 131, a lower piston 132, and a connecting pipe 133. The housing 1 is also provided with several control switches 5. The connecting pipe 133 is located between the upper piston 131 and the lower piston 132. The oil pump 12 drives and connects to the connecting pipe 133. The control switches 5 are located within the moving space of the upper piston 131, that is, the water-permeable zone is divided into two areas. The moving spaces of the upper piston 131 and the lower piston 132 are each a water-permeable zone, and the two water-permeable zones are not connected. The control switches 5 are located below the drain outlet 4 on the same side. The control switches 5 can be level switches or solenoid valves. When control switch 5 is a level switch, the upward floating process can be set. When the liquid level reaches the vicinity of control switch 5 or the upper piston 131 moves to the position of control switch 5, control switch 5 is in a closed state. When control switch 5 is a solenoid valve, during the upward floating process, when the liquid level reaches the vicinity of control switch 5 or the upper piston 131 moves to the position of control switch 5, control switch 5 is in a closed state, ensuring that liquid does not enter the housing from control switch 5 during the upward floating process. Under the force of the oil pump 12, the liquid inside the connecting pipe 133 transmits force to the upper piston 131 and the lower piston 132, causing the pistons to move. In the process of descent, the connecting pipe 133 pushes the upper piston 131 and the lower piston 132 to move simultaneously toward the corresponding drain outlet 4, discharging the water in the permeable zone 113 until equilibrium is reached. After the upper piston 131 passes the control switch 5, the control switch 5 remains closed. When the upper piston 131 moves to the position of the drain outlet 4 on the same horizontal line, it can no longer move upward, blocking the drain outlet 4 and stopping its upward movement. During the descent, the process is the opposite of the ascent. The connecting pipe 133 pushes the upper piston 131 and the lower piston 132 to retract, that is, the upper piston 131 and the lower piston 132 move simultaneously toward the connecting pipe 133, and the seawater returns to the permeable zone 113. 3. When the floating state reaches equilibrium, the upper piston 131 and lower piston 132 both block the drain outlet 4 and the control switch 5, keeping them tightly closed. A large amount of water in the permeable zone 113 is discharged, which reduces the weight of the net cage. When the submerged state reaches equilibrium, the upper piston 131 and lower piston 132 are retracted and return to the vicinity of the connecting pipe 133. At this time, there is a large amount of seawater in the permeable zone 113, and the column 22 is immersed in the seawater. The control switch 5 is set so that when the net cage sinks, the auxiliary liquid can quickly enter the shell 1. When the liquid level in the shell 1 exceeds the control switch 5, the control switch 5 will not allow the liquid in the shell 1 to be discharged.

[0043] It is worth noting that the outer walls of the upper piston 131 and the lower piston 132 are provided with rubber rings, which can further reduce the gap between the upper piston 131 and the lower piston 132 and the inner wall of the housing, and prevent liquid from entering the connecting pipe 133.

[0044] Furthermore, the controllable buoyancy self-circulation system 1 also includes a first connecting pipe 14 and a second connecting pipe 15. The first connecting pipe 14 is located between the oil pump 12 and the bidirectional jack 13. The first connecting pipe 14 contains an oil delivery pipe, a flexible integrated pipe, and a vent pipe that communicates with the atmosphere. The function of the vent pipe is to maintain the air pressure balance in the area between the upper piston 131 and the lower piston 132 during the opening and closing of the jack. The second connecting pipe 15 extends from the oil pump 12 to the outer wall of the housing 11, and this end of the second connecting pipe 15 can be connected to a solar energy device or a wind power device to supply power to the oil pump 12 through solar power generation or wind power generation. The second connecting pipe 15 contains a flexible integrated pipe. The first connecting pipe 14 and the second connecting pipe 15 can be made of corrosion-resistant and high-hardness plastic material. The flexible integrated pipe has good insulation, corrosion resistance, and good isolation effect. In summary, both the first connecting pipe 14 and the second connecting pipe 15 can withstand the impact of large waves and ocean currents without affecting their conductivity.

[0045] In addition, since the cages can float, users can clean them without having to wait for them to float completely, which greatly reduces the cost of later maintenance.

[0046] A detailed description of the complete structure of the submersible floating cage system 2:

[0047] The hollow tube 23 includes a top annular hollow tube 231 and a bottom annular hollow tube 232. The bottom annular hollow tube 232 is located on the outer ring of the float 24, and the surrounding corridor 261 is located above the top annular hollow tube 231.

[0048] The bottom annular hollow tube 232 and the float ring 24 are directly connected by a connecting rod 27, and one end of the connecting rod 27 is connected to the shell 11 of the controllable buoyancy self-circulation system 1.

[0049] The support member 25 includes a horizontal support member 251, a mesh support member 252, and an inclined support member 253. The horizontal support member 251 passes through the column 22. The mesh support member 252 is located between the horizontal support members 251. The mesh support member 252 is also located between the bottom annular hollow tube 232 and the float 24, and between the float 24 and the shell 11. The inclined support member 253 is located between the horizontal support member 251 and the column 22. It is worth noting that the top surface of the net cage does not have a mesh support member 252. When the net cage is submerged to its lowest point, the water does not completely submerge the net cage. The floating corridor assembly 26 and the top annular hollow tube 231 are above the water surface, with a height of 2m above the water surface. This part can prevent the farmed fish from jumping out, so the top surface is not covered by a mesh support member 252. Only the sides and bottom of the net cage are covered by mesh support members 252.

[0050] Reference Figure 1and Figure 3 The two diagonal support members 253 intersect and connect to the column, which is also a cable-connected column, so that the stress state of the whole structure is consistent.

[0051] Furthermore, the column 22, the hollow tube 23, the guardrail 263 and the connecting rod 27 are all made of high-density polyethylene (HDPE), and the cable 21 is made of fiber-reinforced composite material, namely FRP cable 21.

[0052] Advantages of the overall structural design:

[0053] 1) HDPE possesses excellent corrosion resistance, leak-proof performance, moisture resistance, and high tensile strength. It should not only be economically viable but also feature stable and reliable joints. In marine environments, HDPE, as an electrical insulator, resists the corrosion of acids, alkalis, and salts, and will not rust or undergo electrochemical corrosion. The hollow tubes 23, guardrails 263, and connecting rods 27 made of HDPE have good sealing performance and low permeability, ensuring the durability of the cages.

[0054] 2) HDPE is wave-compliant, meaning it bends with the waves it passes through rather than remaining rigid. It is a material with high tensile strength and good flexibility. Truss structures can fully utilize the tensile and compressive strength of HDPE pipes, improving the load-bearing capacity of the structure. Truss systems allow for larger spans in the structure. The relatively light material of HDPE pipe trusses can reduce the self-weight of the building, which is beneficial for the floating and submerging of the cages. It is also easy to handle and install, requiring less manpower and equipment. It can also withstand a certain degree of bending during installation, reducing the difficulty of installation.

[0055] 3) The design of the inclined support component 253 strengthens the overall structure and helps the cage resist external forces such as waves and ocean currents, ensuring the cage's sturdiness and reliability in complex marine environments.

[0056] 4) The mesh support 252 surrounds the hollow tube 23 and the column 22. The mesh support 252 is permeable to water in all directions and can also prevent farmed animals from escaping.

[0057] 5) Convenient cleaning and maintenance: Fishermen bring their own high-pressure water guns to clean the net cages. When the net cages need cleaning, the fishermen control the net cages to float normally and use their own high-pressure water guns to clean the posts 22 and the seaweed, shellfish and other attached materials on the nets.

[0058] Furthermore, the submersible floating cage system 2 also includes a floating corridor assembly 26, which includes a surrounding corridor 261 and three branch corridors 262. The surrounding corridor 261 is located on the top surface of the entire submersible floating cage system 2 and is fixedly connected to the top of the column 22. One end of each branch corridor 262 is connected to the surrounding corridor 261, and the other end is fixedly connected to the controllable buoyancy self-circulation system 1. The three branch corridors 262 are distributed at intervals around the controllable buoyancy self-circulation system 1. Both the surrounding corridor 261 and the three branch corridors 262 include guardrails 263 and several crossbars 264. The guardrails 263 are located on both sides of the crossbars 264. During cleaning or routine maintenance, the current cage can be cleaned and maintained along the floating corridor assembly 26.

[0059] Furthermore, the anchor cable system 3 includes a hemp rope 31, a chain 32, and an anchor hook 33. The hemp rope 31 is mounted on the column 22, one end of the chain 32 is connected to the hemp rope 31, and the anchor hook 33 is mounted on the other end of the chain 32. A fishing boat is used to pull the anchor hook 33 further away to make the hemp rope 31 and chain 32 as taut as possible, and then let it sink naturally, with the anchor hook 33 penetrating downwards and fixing to the seabed; and the anchor hook 33 can be replaced by a concrete block.

[0060] Overall, the oil pump 12 can also be connected to the control system to achieve remote monitoring and control, improve the efficiency and accuracy of aquaculture management, and improve aquaculture efficiency, reduce environmental risks, and facilitate management and operation because it can control the floating and sinking of the net cages.

[0061] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
