Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture cages, and in particular to a large-scale deep-sea aquaculture cage based on an automatic feeding function. Background Art

[0002] Deep-sea aquaculture cages are a new type of aquaculture device developed in recent years to address the challenges of limited space, environmental pollution, and excessive stocking density in traditional offshore aquaculture. Consisting primarily of a sturdy and durable cage frame, cage materials, feeding systems, and ancillary facilities, they are designed to withstand strong winds and waves and other natural conditions found in deep-sea environments, providing a relatively independent aquaculture space for the growth and reproduction of marine organisms (such as fish and shellfish). Compared to traditional aquaculture cages, deep-sea aquaculture cages offer a larger aquaculture area, enabling higher stocking densities and better water quality, thereby contributing to increased aquaculture production and efficiency.

[0003] Patent publication number CN118303352A discloses a deep-sea aquaculture cage comprising a main frame and a floating assembly, wherein the floating assembly comprises a bottom frame and a plurality of first inflatable floats; the bottom frame is disposed at the bottom of the main frame, and the bottom of the bottom frame has limiting columns, wherein the limiting columns and the bottom surface of the bottom frame enclose a limiting space, and the first inflatable floats are disposed within the limiting space. The present invention installs the first inflatable floats within the limiting space enclosed by the limiting columns and the bottom frame, and utilizes the limiting columns to limit the range of movement of the first inflatable floats, preventing the first inflatable floats from moving away from the main frame, thereby enabling the first inflatable floats to always support the main frame and stably float on the sea surface.

[0004] The existing technology has the following defects:

[0005] At present, there is still a certain waste problem when feeding large-scale deep-sea aquaculture cages. Due to the complex structure of the aquaculture cages and the large fluctuations in the aquaculture environment, it is difficult for the feeding device to accurately control the amount and position of feed, resulting in excessive feed sometimes being fed, and even some feed floating to the water surface or sinking to the bottom of the sea, unable to be effectively ingested by the aquaculture. This not only brings economic losses, but may also pollute water quality and damage the health of the marine ecological environment. In addition, if wasted feed accumulates around the cages, it can easily induce the spread of diseases, affect the growth and reproduction of fry, and thus affect the aquaculture efficiency. Therefore, how to reduce feed waste and ensure the healthy growth and reproduction of fry by optimizing feeding technology and improving feed delivery accuracy is a key issue that needs to be urgently addressed in current deep-sea aquaculture technology. Summary of the Invention

[0006] In view of the above problems in the existing technology, a large-scale deep-sea aquaculture cage with automatic feeding function is proposed.

[0007] The present application provides a large-scale deep-sea aquaculture cage with an automatic feeding function, the purpose of which is to solve the problems that the structure of the aquaculture cage is complex, the aquaculture environment fluctuates greatly, and the feeding device is difficult to accurately control the amount and position of feed.

[0008] The technical solution of the present invention is: a large-scale deep-sea aquaculture cage with an automatic feeding function, comprising a pair of net hoops, a fishing net sleeved on the pair of net hoops, a feeding pipe passing through the center points of the pair of net hoops, a plurality of feeding holes opened on the wall of the feeding pipe, an unsealed material receiving net wrapped around the outer periphery of the feeding pipe, the material receiving net being connected to the feeding pipe via a plurality of sets of cables, each set of cables comprising two cables, one end of the two cables being connected to the two sides of the material receiving net, and the other end being passed into the feeding pipe from above; in a first state, the plurality of cables are tightened in the feeding pipe, and the material receiving net is wrapped around the outer periphery of the feeding pipe; in a second state, the plurality of cables are extended outside the feeding pipe, and the material receiving net is placed below the feeding pipe in an open state;

[0009] It also includes a retraction and extension component for controlling the tightening and extension of the cable.

[0010] This solution, by placing the feeding pipe in the middle of the cage, effectively solves the uneven feeding problem seen in traditional aquaculture methods. The feeding pipe design ensures even distribution of feed, preventing it from pooling on one side of the cage or floating on the surface. This ensures that the fish in the seawater receive feed evenly, improving feeding efficiency and aquaculture results.

[0011] The feed receiving net provides flexibility and adaptability to the aquaculture environment. Controlled by a cable, the net can be switched from its first position to its second position as needed. In the second position, the net can be deployed and positioned beneath the feeding duct, effectively collecting feed and preventing it from settling or being carried away by waves. This ensures a clean aquaculture environment and reduces the risk of environmental pollution.

[0012] Furthermore, the feeding pipe is formed by threaded connection of multiple spliced ​​pipes.

[0013] By adopting the above scheme, the spliced ​​pipes can be freely combined to form spliced ​​pipes of different lengths to match cages of different sizes.

[0014] Furthermore, the retracting and releasing assembly includes a first retaining ring and a second retaining ring arranged on the inner wall of the spliced ​​pipe, a winding wheel is rotatably arranged between the first retaining ring and the second retaining ring, a through-hole is provided on the wall of the spliced ​​pipe corresponding to the winding wheel, the two cables are passed through the through-hole and wound around the winding wheel, a sliding tube is slidingly provided in the first retaining ring and the second retaining ring, a third retaining ring is provided on the right end of the sliding tube, a spring is abutted between the third retaining ring and the second retaining ring, a limiting groove is provided on the third retaining ring, a limiting strip is provided along the axis on the inner wall of the feeding pipe on the right side of the second retaining ring, the limiting groove slides on the limiting strip, a spiral groove is provided on the outer wall of the sliding tube, a spiral protrusion is provided on the inner wall of the winding wheel, and the spiral protrusion slides in the spiral groove.

[0015] The design of the retractor assembly allows for precise control of the tension and extension of the cable. This mechanism ensures that the feed net can be opened when needed, ensuring that the fish feed remains effectively within the cage. Traditional aquaculture systems often rely on manual or rudimentary feeding methods, which can lead to uneven feeding and waste. Through automated control, the retractor assembly makes the feeding process more efficient and energy-efficient.

[0016] Furthermore, a conical retaining ring is provided at the right opening of the sliding tube, and the conical retaining ring is elastic.

[0017] By adopting the above solution, by setting the conical baffle ring, when the feed is transported into the feeding pipe, the resistance of the feed increases when passing through the conical baffle ring, and the feed flow pushes the sliding tube to slide to the left, so that the material receiving net switches from the first state to the second state.

[0018] Furthermore, the length of the feeding pipe exceeds the distance between a pair of net hoops, and a fishing net is connected between the end of the feeding pipe and the outer edge of the net hoop.

[0019] By adopting the above solution, by setting the length of the feeding pipe to be wider than the spacing of the net hoops, the shape of the fishing net is made into a spindle shape. The spindle-shaped design allows the water flow and wave forces acting on the cage in the water to be evenly distributed, thereby reducing the risk of capsizing and tilting. Such a structure also helps to improve water circulation, ensure good flow of water quality in the cage, and promote the optimization of the breeding environment.

[0020] Furthermore, both ends of the feeding pipe are provided with connectors, and a plurality of strong ropes are provided on the connectors, some of the strong ropes are connected to anchors arranged on the seabed, and some of the ropes are connected to buoys arranged on the sea surface.

[0021] By adopting the above solution, the anchoring member is connected to the buoy and the cage, so as to fix the position of the cage and resist the ocean current.

[0022] Furthermore, a circle of floats is provided on the edge of the mesh hoop, and the floats have double chambers. The two chambers of the floats located on the upper layer are both filled with air, the upper chamber of the floats located on the middle layer is filled with air, and the lower chamber is filled with seawater, and the two chambers of the floats located on the lower layer are both filled with seawater.

[0023] By adopting the above scheme, this design controls the buoyancy and center of gravity of the float by changing the ratio of water and air, thereby achieving balance and stability of the cage.

[0024] Furthermore, a feed pipe is provided at the end of the feeding pipe, and the feed pipe is connected to a pump.

[0025] By adopting the above solution, the fish feed is mixed with seawater by connecting a pump and then pumped into the feeding pipe through the feed pipe.

[0026] Furthermore, the mesh size of the material receiving net is smaller than the mesh size of the fishing net.

[0027] By adopting the above solution, the mesh holes of the receiving net are densely arranged, so that the receiving net plays the role of receiving the spilled fish feed, reducing feed sedimentation and improving feed utilization.

[0028] Beneficial effects of the present invention:

[0029] 1. Placing the feeding pipe in the middle of the cage effectively solves the problem of uneven feeding of fry in traditional aquaculture methods. This feeding pipe design ensures even distribution of feed, preventing it from pooling on one side of the cage or floating on the surface. This ensures that the fry in the seawater receive feed evenly. This uniform feeding method not only improves feeding efficiency but also better ensures the healthy growth and reproduction of the fish, significantly enhancing aquaculture results.

[0030] 2. The design of the retractable assembly allows for precise control of the tension and extension of the cable. This mechanism ensures that the feeding net can be opened when needed, ensuring that the fish feed is effectively retained in the cage. This solves the problem of slow feeding of fry during the breeding period, which causes feed to be consumed and scattered outside the cage, resulting in uneven feeding or waste.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] Example, see Figure 1-11The invention provides a large-scale deep-sea aquaculture cage with automatic feeding function, comprising a pair of net hoops 1 and a fishing net 2 mounted on the pair of net hoops 1. A feeding pipe 3 is passed through the center points of the pair of net hoops 1. A plurality of feeding holes 4 are opened on the wall of the feeding pipe 3. The outer periphery of the feeding pipe 3 is covered with an open material receiving net 5. The material receiving net 5 is connected to the feeding pipe 3 by multiple groups of cables 6. Each group of cables 6 consists of two, one end of the two cables 6 is connected to the two sides of the material receiving net 5, and the other end is passed into the feeding pipe 3 from above; in a first state, the multiple groups of cables 6 are tightened in the feeding pipe 3, and the material receiving net 5 is covered on the outer periphery of the feeding pipe 3; in a second state, the multiple groups of cables 6 are extended outside the feeding pipe 3, and the material receiving net 5 is placed under the feeding pipe 3 in an open state; and a retraction component is also included to control the tightening and extension of the cables 6.

[0046] In this embodiment, multiple fixing ropes are arranged obliquely between a pair of net hoops 1, and the fishing net 2 is covered on the outside of the fixing ropes. The pull rope 6 is made of nylon. Reinforced edges are fixed on both sides of the material receiving net 5, and holes are opened on the reinforced edges. The pull rope 6 passes through the holes on the reinforced edges and is connected to the material receiving net 5.

[0047] Placing the feeding pipe 3 in the middle of the cage effectively solves the uneven feeding problem seen in traditional aquaculture methods. The design of the feeding pipe 3 ensures even distribution of feed, preventing it from gathering on one side of the cage or floating on the surface. This ensures that the fish in the seawater receive the feed evenly, improving feeding efficiency and aquaculture results.

[0048] The feed receiving net 5 provides flexibility and adaptability to the aquaculture environment. Controlled by a cable 6, the net 5 can be switched from a first position to a second position as needed. In the second position, the net 5 can be unfolded and placed beneath the feeding duct 3, effectively collecting feed and preventing it from settling or being carried away by waves. This ensures a clean aquaculture environment and reduces the risk of environmental pollution.

[0049] Reference Figure 7 The feeding pipe 3 is formed by threaded connection of multiple spliced ​​pipes 7.

[0050] The splicing pipes 7 can be freely combined to form splicing pipes 7 of different lengths to match cages of different sizes.

[0051] Reference Figure 3-Figure 8The retracting and unretracting assembly includes a first retaining ring 8 and a second retaining ring 9 arranged on the inner wall of the splicing pipe 7, a winding wheel 10 is rotatably arranged between the first retaining ring 8 and the second retaining ring 9, a through-hole 11 is opened at the pipe wall of the splicing pipe 7 corresponding to the winding wheel 10, and the two cables 6 pass through the through-hole 11 and are wound around the winding wheel 10, a sliding tube 12 is slidably arranged in the first retaining ring 8 and the second retaining ring 9, a third retaining ring 13 is provided at the right end of the sliding tube 12, a spring 14 is abutted between the third retaining ring 13 and the second retaining ring 9, a limiting groove 15 is provided on the third retaining ring 13, and a limiting strip 16 is provided along the axis of the inner wall of the feeding pipe 3 on the right side of the second retaining ring 9, the limiting groove 15 slides on the limiting strip 16, a spiral groove 17 is opened on the outer wall of the sliding tube 12, and a spiral protrusion 18 is provided on the inner wall of the winding wheel 10, which slides in the spiral groove 17.

[0052] In this embodiment, the first retaining ring 8 is arranged on the left side of the second retaining ring 9, and the side surfaces of the winding wheel 10 are respectively in contact with the first retaining ring 8 and the second retaining ring 9, and two groups of limit grooves 15 and limit grooves 15 are respectively provided to limit the sliding tube 12 from sliding along the axial direction of the spliced ​​pipe 7. The two cables 6 are wound on the winding wheel 10 in the same direction. After passing through the through hole 11, the two cables 6 are respectively connected to the two sides of the material receiving net 5 in opposite directions. In the process of the sliding tube 12 moving to the left, the spring 14 is squeezed by the third retaining ring 13 and the second retaining ring 9, and the spiral protrusion 18 slides in the spiral groove 17 to rotate the winding wheel 10, and the cable 6 extends from the winding wheel 10 through the through hole 11 to the outside of the spliced ​​pipe 7.

[0053] The design of the retractable assembly enables the tightening and extension of the cable 6 to be precisely controlled. This mechanism ensures that the receiving net 5 can be opened when needed, thereby ensuring that the fish feed can be effectively retained in the net cage. Traditional aquaculture systems often rely on manual or simple feeding methods, which are prone to uneven feeding or waste. Through automated control, the retractable assembly makes the feeding process more efficient and energy-saving. The flexible control of the cable 6 not only improves the accuracy of feeding, but also avoids feed waste. When the retractable assembly controls the cable 6 to extend, the receiving net 5 will be in an open state, accurately receiving and distributing feed, minimizing the scattering and ineffective falling of feed, improving feed utilization, and thus reducing aquaculture costs.

[0054] Reference Figure 7 The right opening of the sliding tube 12 is provided with a conical retaining ring 19, and the conical retaining ring 19 is elastic.

[0055] By providing the conical retaining ring 19, when the feed is transported into the feeding pipe 3, the resistance of the feed increases when passing through the conical retaining ring 19, and the feed flow pushes the sliding tube 12 to slide leftward, so that the receiving net 5 switches from the first state to the second state.

[0056] Reference Figure 2The length of the feeding pipe 3 exceeds the distance between a pair of net hoops 1 , and a fishing net 2 is connected between the end of the feeding pipe 3 and the outer edge of the net hoop 1 .

[0057] By setting the length of the feeding pipe 3 to be wider than the spacing of the net hoop 1, the shape of the fishing net 2 is made into a spindle shape. The spindle shape design evenly distributes the water flow and wave force exerted on the cage in the water, thereby reducing the risk of capsizing and tilting. Such a structure also helps to improve water circulation, ensure good flow of water quality in the cage, and promote the optimization of the breeding environment.

[0058] Reference Figure 3 Both ends of the feeding pipe 3 are provided with connecting parts 20, and multiple strong ropes 21 are provided on the connecting parts 20. Some of the strong ropes 21 are connected to anchors 22 set on the seabed, and some ropes are connected to buoys 23 set on the sea surface.

[0059] By connecting the anchor 22 to the buoy 23 and the net cage, the position of the net cage is fixed and the effect of resisting ocean current is achieved.

[0060] Reference Figure 1 A circle of floats 24 is provided on the edge of the net hoop 1. The floats 24 have double chambers. The two chambers of the float 24 located on the upper layer are filled with air. The upper chamber of the float 24 located on the middle layer is filled with air, and the lower chamber is filled with seawater. The two chambers of the float 24 located on the lower layer are both filled with seawater.

[0061] In this embodiment,

[0062] This design controls the buoyancy and center of gravity of the float 24 by changing the ratio of water to air, thereby achieving balance and stability of the cage.

[0063] Reference Figure 3 The end of the feeding pipe 3 is provided with a feeding pipe 25, which is connected to the pump.

[0064] By connecting a pump, the fish feed is mixed with seawater and then pumped into the feeding pipe 3 through the feed pipe 25. In other possible applications, the cage can be equipped with a timed feeding device. The mixing device regularly delivers the feed to a container for mixing, and then pumps it into the feeding pipe 3 through the feed pipe. Excessive feeding can easily cause water pollution, while too little can affect fish growth. The feeding amount should be adjusted according to the size, number, and growth status of the cultured fish. The appropriate feeding amount can be determined by calculating factors such as the fish's metabolic rate and the digestibility of the feed. Fish cultured in deep-sea cages may experience changes in their appetite due to environmental factors, so the feeding frequency needs to be adjusted according to the fish's growth cycle. Generally, the feeding frequency is adjusted one to three times a day, although the feeding frequency varies for different fish species. The water currents in deep-sea cages are strong, and feed is easily dispersed in the water. Therefore, it is more appropriate to use feed with poor water solubility and poor dissolution. This can reduce feed waste and ensure effective fish intake.

[0065] Reference Figure 1 and Figure 3 The mesh size of the material receiving net 5 is smaller than the mesh size of the fishing net 2.

[0066] By adopting the above solution, the mesh holes of the receiving net 5 are densely arranged, so that the receiving net 5 plays the role of receiving the spilled fish feed, reducing feed sedimentation and improving feed utilization.

[0067] Working principle of the present invention:

[0068] When not feeding, the device is in the first state, multiple groups of cables 6 are tightened in the feeding pipe 3, and the material receiving net 5 is wrapped around the outer circumference of the feeding pipe 3. When feeding, the feed is pumped into the feeding pipe 3 by the pump. The resistance of the feed increases when passing through the conical retaining ring 19, and the feed flow pushes the sliding tube 12 to slide to the left. During the movement of the sliding tube 12 to the left, the spring 14 is squeezed by the third retaining ring 13 and the second retaining ring 9, and the spiral protrusion 18 slides in the spiral groove 17 to rotate the winding wheel 10, and the cable 6 extends from the winding wheel 10 through the through hole 11 to the splicing hole. When the feeding is completed, the spring 14 pushes the sliding tube 12 to slide to the right. During the movement of the sliding tube 12 to the right, the spiral protrusion 18 slides in the spiral groove 17 to rotate the winding wheel 10, and the cable 6 is wound on the winding wheel 10, so that the cable 6 extending out of the splicing pipe 7 is retracted onto the winding wheel 10, and the material receiving net 5 is re-wrapped on the outer periphery of the feeding pipe 3, and the device returns to the first state.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
