[0001] This invention relates to the field of deep-sea aquaculture technology, and in particular to a rectangular net cage device and deep-sea aquaculture and fishing equipment. Background Technology

[0002] To ensure national food security and build a diversified food supply system, we must not only store grain in the land and through technology, but also in the sea. Since the country proposed the construction of marine ranches, deep-sea aquaculture cages have flourished. These cages are mainly used in open sea areas more than 10 kilometers offshore and at depths of over 20 meters for the cultivation of fish, shellfish, and other marine organisms. Deep-sea aquaculture cages effectively utilize the vast waters of the deep sea, overcoming the spatial limitations of near-shore aquaculture; they have strong resistance to wind and waves, enabling stable operation even in harsh sea conditions; they offer high aquaculture efficiency, equipped with automated feeding and monitoring systems, reducing labor costs and increasing yields; and they provide a superior aquaculture environment, with clean and unobstructed water quality in the deep sea, which helps improve the quality of farmed organisms and reduce disease risks.

[0003] While deep-sea aquaculture cages have the aforementioned advantages, the traditional method of netting and harvesting fish is complex, resulting in a long harvesting time. This can easily cause fish to become stunned or even die, affecting their appearance and taste. Summary of the Invention

When the guide ropes and pull ropes are pulled or released, the guide ropes can adjust the height of the guide rings, and the pull ropes can adjust the depth of the fishing net.

[0006] In one embodiment, each of the pull ropes is connected to one corner of the fishing net, and all the pull ropes are divided into a lifting section and a fish-gathering section. The lifting section is used to lift the fishing net to the top of the box body, and the fish-gathering section is used to gather the four corners of the fishing net together.

[0007] In one embodiment, each of the guide ropes has an upward positioning section near the top fixing ring and a downward positioning section away from the top fixing ring. Pulling the upward positioning section can raise the guide ring, and pulling the downward positioning section can lower the guide ring.

[0030] This invention proposes a rectangular wire mesh cage device 100.

[0031] Please see Figure 1 and Figure 2In one embodiment of the present invention, the rectangular net cage device 100 includes a cage body 1, a fishing net 2, four guide ropes 4, and four guide rings 5. The cage body 1 has a fish-raising space 1a inside. The cage body 1 has four bottom fixing rings 11, all of which are located at the bottom of the fish-raising space 1a. The cage body 1 also has four top fixing rings 12, all of which are located at the top of the fish-raising space 1a. All the bottom fixing rings 11 and all the top fixing rings 12 are located at the connection between adjacent side walls of the fish-raising space 1a. The fishing net 2 has... Four pull ropes 3 are connected to the four corners of the fishing net 2; the fishing net 2 is located in the receiving space 1a, and each pull rope 3 is threaded through a top fixing ring 12; each guide rope 4 is movably threaded through a bottom fixing ring 11 and a top fixing ring 12; each guide rope 4 is connected to a guide ring 5, and each pull rope 3 is threaded through a guide ring 5; each guide ring 5 is located between a top fixing ring 12 and a bottom fixing ring 11; wherein, when the guide rope 4 and the pull rope 3 are pulled or released, the guide rope 4 can adjust the height of the guide ring 5, and the pull rope 3 can adjust the depth of the fishing net 2.

[0032] In this embodiment, the main body 1 of the fish tank is placed in a predetermined aquaculture area to ensure its stability. The main body 1 contains a fish-raising space 1a, with four bottom fixing rings 11 at the bottom and four top fixing rings 12 at the top. These fixing rings are located at the junctions of adjacent side walls of the fish-raising space 1a. A fishing net 2 is installed inside the main body 1, with its four corners connected to the four top fixing rings 12 at the top of the main body 1 via pull ropes 3. One end of each guide rope 4 passes through a bottom fixing ring 11, and the other end passes through a top fixing ring 12, connecting to a guide ring 5. Each guide ring 5 is located between a top fixing ring 12 and a bottom fixing ring 11. By pulling or releasing the guide rope 4, the height of the guide ring 5 can be adjusted, and thus the depth of the fishing net 2 can be adjusted by pulling the rope 3. When raising or lowering the fishing net 2, the operator only needs to use a winch 7 or a winch plate to adjust the height of the guide ring 5, and then pull the rope 3 to easily raise or lower the fishing net 2. This design makes the operation of setting up and retrieving the fishing net 2 very simple, greatly reducing operation time and labor intensity.

[0033] The rectangular net cage device 100 of the present invention includes a cage body 1, a fishing net 2, four guide ropes 4, and four guide rings 5. The cage body 1 is placed in a predetermined aquaculture area to ensure its stability. The fishing net 2 is installed inside the cage body 1, with its four corners connected to four top fixing rings 12 on the top of the cage body 1 via pull ropes 3. One end of the guide rope 4 passes through the bottom fixing ring 11 and the top fixing ring 12 and connects to the guide ring 5. The guide ring 5 is located between the top fixing ring 12 and the bottom fixing ring 11. By pulling or releasing the guide rope 4, the height of the guide ring 5 can be adjusted, and thus the depth of the fishing net 2 can be adjusted by pulling the rope 3. During the fishing process, the operator only needs to adjust the height of the guide ring 5 and then pull the rope 3 to pull up the fishing net 2. The operation is simple, the fishing time is short, and the fishing efficiency is improved. The rectangular net cage device 100 of the present invention has significant convenience and efficiency in setting up and taking down the fishing net 2. Through the cooperation of the guide ropes 4 and the guide rings 5, the operator can easily adjust the depth of the fishing net 2 without complicated net pulling operations. This design not only reduces operation time but also minimizes stress on fish, avoiding the fainting and death that can occur with traditional seine netting methods, thus improving fish quality and marketability. Furthermore, the simplified operation reduces labor costs and increases overall harvesting efficiency, making deep-sea aquaculture more efficient and sustainable.

[0034] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 Each pull rope 3 is connected to one corner of the fishing net 2. All the pull ropes 3 are divided into lifting sections 31 and fish-gathering sections 32. The lifting sections 31 are used to lift the fishing net 2 to the top of the box body 1, and the fish-gathering sections 32 are used to gather the four corners of the fishing net 2.

[0035] In one embodiment, the pull rope 3 of the rectangular net cage device 100 is designed with multiple sections to improve the efficiency and convenience of setting up and retrieving the fishing net 2. Each pull rope 3 is connected to one corner of the fishing net 2 to ensure that the fishing net 2 remains stable during the lifting process. All pull ropes 3 are divided into two parts: a lifting section 31 and a fish-gathering section 32. The lifting section 31 extends from the corner of the fishing net 2, passes through the guide ring 5 to the top fixing ring 12 at the top of the cage body 1, and is then fixed to the winch base of the deck 6, so that the winch 7 can lift the fishing net 2 to the top of the cage body 1. The fish-gathering section 32 extends from the corner of the fishing net 2, with its other end being a free end, and is used to gather the four corners of the fishing net 2 together. When retrieving the net, the operator first lifts the fishing net 2 to the top of the cage body 1 through the lifting section 31, and then gathers the four corners of the fishing net 2 together through the fish-gathering section 32, so that the fish in the fishing net 2 are gathered in a smaller space, making it easier to catch. The rectangular net cage device 100 of the present invention significantly improves the efficiency and convenience of setting up and retrieving the fishing net 2 by dividing the pull rope 3 into a lifting section 31 and a fish-gathering section 32. When retrieving the net, the lifting section 31 can quickly lift the fishing net 2 to the top of the cage body 1, reducing operation time and labor intensity. The fish-gathering section 32 concentrates the four corners of the fishing net 2, allowing the fish to gather in a smaller space, facilitating harvesting, reducing stress on the fish, and improving the quality and marketability of the fish. Furthermore, this design reduces labor costs during the harvesting process, improves overall harvesting efficiency, and makes deep-sea aquaculture more efficient and sustainable. For example, in practical applications, operators can complete the setting up and retrieving of the fishing net 2 in minutes, greatly improving work efficiency compared to traditional methods.

[0036] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 Each guide rope 4 has a positioning upward adjustment section 41 near the top fixed ring 12 and a positioning downward adjustment section 42 away from the top fixed ring 12. Pulling the positioning upward adjustment section 41 can raise the guide ring 5, and pulling the positioning downward adjustment section 42 can lower the guide ring 5.

[0037] In this embodiment, the guide rope 4 of the rectangular net cage device 100 is designed with multiple sections to improve the efficiency and convenience of adjusting the depth of the fishing net 2. Each guide rope 4 is divided into two parts: a positioning upward adjustment section 41 near the top fixing ring 12 and a positioning downward adjustment section 42 away from the top fixing ring 12. The specific positions and lengths of the positioning upward adjustment section 41 and the positioning downward adjustment section 42 can be adjusted according to actual needs. During operation, when it is necessary to raise the guide ring 5, the operator only needs to pull the positioning upward adjustment section 41, and the guide ring 5 will move upward along the guide rope 4; when it is necessary to lower the guide ring 5, the operator pulls the positioning downward adjustment section 42, and the guide ring 5 will move downward along the guide rope 4.

[0038] The rectangular net cage device 100 of the present invention significantly improves the efficiency and convenience of adjusting the depth of the fishing net 2 by dividing the guide rope 4 into a positioning upward adjustment section 41 and a positioning downward adjustment section 42. This design allows operators to quickly and accurately adjust the height of the guide ring 5, thereby adjusting the depth of the fishing net 2, without complicated operating procedures, greatly reducing operating time and labor intensity. Furthermore, this design improves the adaptability and flexibility of the net cage, enabling it to better cope with changes in water flow and temperature in different sea areas, reducing stress responses to fish caused by environmental changes. For example, in practical applications, operators can complete the adjustment of the guide ring 5 in seconds, significantly improving work efficiency compared to traditional methods. This design not only improves aquaculture efficiency but also enhances the quality and appearance of fish, making deep-sea aquaculture more efficient and sustainable.

[0039] In one embodiment of the present invention, please refer to Figure 2 The diameter of each guide ring 5 is larger than that of the top fixing ring 12 and the bottom fixing ring 11.

[0040] In one embodiment, the diameter of the guide ring 5 is designed to be larger than the diameters of the top fixing ring 12 and the bottom fixing ring 11 to ensure that the guide ring 5 can slide freely on the guide rope 4, while preventing it from accidentally detaching from the top fixing ring 12 or the bottom fixing ring 11 during operation. Specifically, the diameters of the top fixing ring 12 and the bottom fixing ring 11 can be set according to actual needs. For example, the diameters of the top fixing ring 12 and the bottom fixing ring 11 can be set to 10 cm, while the diameter of the guide ring 5 is designed to be 12 cm. This size difference allows the guide ring 5 to move smoothly up and down on the guide rope 4, and prevents the guide ring 5 from slipping due to its small diameter when the guide rope 4 passes through the fixing rings. In actual operation, when it is necessary to adjust the depth of the fishing net 2, the operator pulls different sections of the guide rope 4 (positioning upward adjustment section 41 or positioning downward adjustment section 42), and the guide ring 5 slides along the guide rope 4, thereby adjusting the movement space of the fishing net 2. For example, in one specific embodiment, when it is necessary to lift the fishing net 2 to the vicinity of the water surface for inspection or fishing, the operator pulls the positioning adjustment section 41, and the guide ring 5 slides upward along the guide rope 4. Since the diameter of the guide ring 5 is larger than that of the fixed ring, it will not slip off the fixed ring during the sliding process, thereby ensuring the stability and reliability of the operation.

[0041] The rectangular net cage device 100 of the present invention significantly improves the stability and reliability of net cage operation by designing the diameter of the guide ring 5 to be larger than that of the top fixing ring 12 and the bottom fixing ring 11. This design allows the guide ring 5 to slide freely on the guide rope 4, while avoiding slippage that may occur due to an excessively small diameter, ensuring the stability and safety of the fishing net 2 when adjusting its depth. Furthermore, this design increases operational flexibility, allowing operators to more easily adjust the depth of the fishing net 2 without worrying about the guide ring 5 accidentally falling off during operation. For example, in practical applications, even in relatively harsh sea conditions, the guide ring 5 can slide stably along the guide rope 4, ensuring the smooth completion of the depth adjustment operation of the fishing net 2. This design not only improves aquaculture efficiency but also reduces fish damage that may result from operational errors, enhancing the quality and appearance of the fish, making deep-sea aquaculture more efficient and sustainable.

[0042] In one embodiment of the present invention, please refer to Figures 4 to 6 The container body 1 is provided with a deck 6, which is connected to the container body 1.

[0043] In this embodiment, a deck 6 is provided on the main body 1 of the cage, and the deck 6 is fixedly connected to the main body 1 by welding, bolting, or other suitable connection methods. The deck 6 is typically located on top of the main body 1, providing operators with a stable platform for daily aquaculture management and harvesting operations. For example, the deck 6 can be made of high-strength steel or composite materials to ensure sufficient strength and durability in harsh marine environments. In specific embodiments, the size of the deck 6 can be designed according to the size of the net cage and actual needs. For example, for a large rectangular net cage, the area of ​​the deck 6 can be designed to be large enough to provide sufficient space for operators to move around. Furthermore, auxiliary facilities such as tool storage boxes and safety railings can be installed on the deck 6 to improve operational convenience and safety.

[0044] The rectangular net cage device 100 of the present invention significantly improves the convenience and safety of operation by setting a deck 6 on the cage body 1. The deck 6 provides operators with a stable platform, making daily aquaculture management and harvesting operations more convenient and efficient. For example, during harvesting, operators can directly operate the pull rope 3 and guide ring 5 on the deck 6 without entering the water or performing dangerous operations at the edge of the net cage, thereby reducing operational risks. In addition, the presence of the deck 6 can also protect operators from the effects of inclement weather, improving work comfort. In practical applications, auxiliary facilities on the deck 6, such as safety railings and tool storage boxes, further enhance the safety and convenience of operation. This design not only improves aquaculture efficiency but also reduces fish damage that may be caused by inconvenient operation, improves the quality and appearance of fish, and makes deep-sea aquaculture more efficient and sustainable.

[0045] In one embodiment of the present invention, please refer to Figures 4 to 6 The deck 6 is provided with four winch bases. The rectangular net cage device 100 includes at least one winch 7. Each winch 7 is detachably connected to a winch base. Each winch 7 is used to receive or release the guide rope 4 and the pull rope 3 so that the fishing net 2 can be raised or lowered.

[0046] In one embodiment, four winch bases are provided on the deck 6, each winch base being mounted on the deck 6. These winch bases are used to install and secure winches 7. Each winch 7 is connected to a winch base via a detachable connection method (such as bolt connection, snap connection, etc.). This design allows the winches 7 to be installed and replaced according to actual needs, improving the flexibility and ease of maintenance of the equipment. Each winch 7 is equipped with a reel and a power unit for receiving or releasing the guide rope 4 and the pull rope 3, thereby controlling the raising and lowering of the fishing net 2. Specifically, the winch base can be designed with a structure having positioning holes and fixing bolts for quick installation and removal of the winch 7. For example, the four winch bases on the deck 6 are located at the four corners of the deck 6, and each base has four positioning holes and four fixing bolts. One end of the pull rope 3 is connected to the corresponding position of the fishing net 2, and the other end is fixed to the reel of the winch 7; the guide rope 4 is connected to the guide ring 5. Operators can control the power unit of winch 7 to raise and lower the guide rope 4 and pull rope 3, thereby adjusting the height of the guide ring 5 and controlling the raising and lowering of the fishing net 2. In practical applications, if a winch 7 malfunctions, operators can quickly replace it with a new one to ensure the normal operation of the equipment. Furthermore, the automated operation of winch 7 improves the efficiency and accuracy of raising and lowering the fishing net 2, reduces manual labor intensity, and increases fishing efficiency. By precisely controlling the raising and lowering of the guide rope 4 and pull rope 3, operators can more smoothly adjust the depth of the fishing net 2, reducing fish damage caused by improper operation and improving the quality and appearance of the fish.

[0047] In one embodiment of the present invention, please refer to Figure 1 The rectangular wire mesh cage device 100 also includes a hanging net 8, which is located within the accommodating space 1a and is connected to the inner wall of the cage body 1.

[0048] In this embodiment, the hanging net 8 is an important component of the rectangular net cage device 100, located within the accommodating space 1a and connected to the inner wall of the cage body 1. Specifically, the hanging net 8 is fixed to the inner wall of the cage body 1 through multiple connection points, which can be welding points, bolt connections, or other suitable fixing methods. The hanging net 8 is typically made of high-strength, corrosion-resistant netting material to ensure its durability in the marine environment. For example, the hanging net 8 can be made of polyethylene or nylon, and the mesh size can be adjusted according to the species and size of the farmed fish. In a specific embodiment, the hanging net 8 can be designed as a multi-layered structure, with each layer having a different mesh size to accommodate fish at different growth stages. For example, the inner layer of the hanging net 8 has a smaller mesh for juvenile fish, while the outer layer has a larger mesh for adult fish. This design not only improves the utilization rate of the farming space but also reduces mutual interference between fish, thereby increasing farming efficiency.

[0049] In one embodiment of the present invention, please refer to Figure 3 The fishing net 2 is equipped with a gravity ring 21, which is connected to the fishing net 2.

[0050] In one embodiment, the fishing net 2 is provided with a gravity ring 21, which is fixedly connected to the fishing net 2 by sewing, binding, or other suitable connection methods. The gravity ring 21 is usually made of high-density materials, such as stainless steel or high-density polyethylene (HDPE), to ensure sufficient weight. In specific embodiments, the gravity ring 21 can be designed as a ring or a circle, with its diameter adjusted according to the size of the fishing net 2 and actual needs. The gravity ring 21 is installed on the bottom edge of the fishing net 2 and fixed to the fishing net 2 through evenly distributed connection points. This design allows the fishing net 2 to maintain a stable vertical state in the water, ensuring that the mesh of the fishing net 2 will not deform due to water flow or fish activity, thereby improving aquaculture efficiency and the living environment of the fish.

[0051] In one embodiment of the present invention, please refer to Figure 1 All top retaining rings 12, all bottom retaining rings 11, and all guide rings 5 ​​are made of stainless steel.

[0052] In this embodiment, all top fixing rings 12, bottom fixing rings 11, and guide rings 5 ​​are made of stainless steel. Stainless steel, due to its excellent corrosion resistance and high strength, is particularly suitable for use in marine environments. In practice, the top fixing rings 12 and bottom fixing rings 11 are respectively installed on the top and bottom of the cage body 1 to fix the guide rope 4 and the pull rope 3. The guide ring 5 is installed on the guide rope 4 to adjust the depth of the fishing net 2. The rectangular net cage device 100 of the present invention significantly improves the corrosion resistance and service life of the device by using stainless steel for the top fixing rings 12, bottom fixing rings 11, and guide rings 5. Stainless steel has excellent corrosion resistance in marine environments, effectively resisting seawater erosion and ensuring that the fixing rings and guide rings 5 ​​maintain good mechanical properties during long-term use. For example, in practical applications, stainless steel fixing rings and guide rings 5 ​​can be used for a long time in harsh marine environments, reducing damage and replacement frequency caused by corrosion. Furthermore, the high strength of stainless steel ensures the stability and safety of the device during operation, reducing the risk of deformation or detachment of the fishing net 2 due to damage to the fixing ring and guide ring 5. This design not only improves aquaculture efficiency but also reduces maintenance costs, making deep-sea aquaculture more efficient and sustainable.

[0053] This invention also proposes a deep-sea aquaculture and fishing device 200, please refer to [link / reference]. Figure 7 The deep-sea aquaculture and fishing equipment 200 includes at least one rectangular net cage device 100 and a suction device 9. The specific structure of the rectangular net cage device 100 is as described in the above embodiments.
