Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, and in particular to a semi-enclosed low-temperature controlled aquaculture cage and a deep-sea aquaculture device. Background Technology

[0002] Deep-sea aquaculture typically refers to a comprehensive fishery production system that operates in sea areas far from the mainland and at depths of less than 20 meters. It relies on aquaculture vessels or large floating aquaculture platforms, along with deep-sea cage facilities, fishing boats, energy supply networks, logistics and supply vessels, and land-based support facilities. This system integrates industrialized green aquaculture, catch transport and supply, marine processing and logistics of aquatic products, and digital management. It is a new full-chain fishery production model that combines "aquaculture-catch-processing." This new aquaculture model has high requirements for marine equipment and technology, while also offering considerable economic benefits.

[0003] The patent with publication number CN114391495B discloses a deep-sea aquaculture cage that can accurately feed fish. It uses cameras, sonar and other instruments to determine the location of most fish, and then controls the induction feeding mechanism to descend to the location of most fish, and then feeds them after luring them. It accurately feeds fish underwater according to their location, reducing feed waste. It uses an integrated installation frame to restrict the fish and prevent farmed organisms from competing for food or wild small fish from blocking the feed outlet. It can also move with the raising and lowering of the induction feeding mechanism without the need for an additional drive structure, thus saving costs.

[0004] The existing technology has the following drawbacks:

[0005] Overly concentrated feeding in aquaculture cages: Concentrated feeding in aquaculture cages is a common feeding method, but when a large amount of feed is placed in a concentrated manner, uneaten feed is prone to accumulate at the bottom of the cage, leading to problems such as organic matter accumulation, eutrophication, and water quality deterioration. In addition, concentrated feeding can also cause some fish to not get enough feed, resulting in feed waste and reduced utilization. Therefore, it is necessary to set up devices to expand the feed placement range to improve feed utilization.

[0006] The impact of water flow on feeding was not considered: the direction of water flow directly affects the distribution of feed in the net cage. If the direction of water flow is the same as the direction of feeding, the feed may be carried away quickly, resulting in uneven feed distribution. Fish in some areas may not be able to eat enough feed, leading to uneven growth and other problems. Therefore, it is necessary to install a device that can change the feeding direction with the change of water flow, so that the feeding direction is always opposite to the direction of water flow, thereby improving the utilization rate of feed.

[0007] Inability to provide multi-level feeding and oxygenation: The inability to achieve multi-level feeding and oxygenation will affect the growth of fish in aquaculture cages and the overall aquaculture effect, leading to problems such as low feed utilization, insufficient oxygen supply, and uneven overall growth. Therefore, it is necessary to install a periodic automatic lifting device to feed and oxygenate the fish in aquaculture cages at multiple levels, thereby improving the overall aquaculture effect. Summary of the Invention

[0008] Given the problems of existing technologies, such as excessive feeding in aquaculture cages, failure to consider the impact of water flow on feeding, and inability to provide multi-level feeding and oxygenation, a semi-enclosed low-temperature controlled aquaculture cage and deep-sea aquaculture device are proposed.

[0009] One aspect of this application provides a semi-enclosed, low-temperature controlled aquaculture cage, the purpose of which is to improve feed utilization and overall aquaculture efficiency by setting up an automatic lifting and rotating feeding and oxygenation device, and multi-level countercurrent feeding and oxygenation.

[0010] The technical solution of the present invention is: a semi-enclosed low-temperature controlled aquaculture cage, including a suspended gravity cage, wherein a lifting and rotating assembly is movably installed on the inner wall of the suspended gravity cage, and an oxygen supply and feeding mechanism is provided inside the lifting and rotating assembly.

[0011] The oxygen supply and feeding mechanism includes a feeding component fixedly connected to the inner wall of the lifting and rotating assembly, and an automatic feeder is fixedly connected to the end of the feeding component.

[0012] The feeding assembly includes a feeding pipe fixedly connected to the inner wall of the lifting and rotating assembly. A partition is fixedly connected to the inner wall of the feeding pipe. A feeding chamber and an air supply chamber are respectively opened between the inner wall of the feeding pipe and the two sides of the partition.

[0013] Using the above scheme, the air conveying chamber continuously conveys air and oxygen, while the feeding chamber feeds the feed in a fixed amount at regular intervals. A partition is used to separate the feeding chamber and the air conveying chamber in the feeding pipe, forming two channels to provide input channels for feeding and oxygen supply.

[0014] Furthermore, a first movable plate is rotatably connected to the inner wall of the feeding pipe, the top of the first movable plate overlaps with the bottom of the partition, and a mixing chamber is also provided on the inner wall of the feeding pipe. The mixing chamber is located below the air supply chamber, and the opening of the first movable plate is located between the air supply chamber and the mixing chamber.

[0015] Furthermore, a fixed seat is fixedly connected to the inner wall of the feeding pipe, the outer wall of the fixed seat overlaps with the inner wall of the first movable plate, a steel wire rope is slidably connected to the inner wall of the fixed seat, one end of the steel wire rope is fixedly connected to the inner wall of the first movable plate, and the steel wire rope is slidably connected to the inner wall of the feeding pipe.

[0016] Using the above scheme, compressed gas is supplied by an oxygen-containing air compressor, which blows the first movable plate through the gas delivery chamber to open it. The first movable plate rotates and fits against the inner wall of the mixing chamber. At the same time, the steel wire rope is pulled to control the opening and closing of the first movable plate.

[0017] Furthermore, the automatic feeder includes a feeder housing fixedly connected to the outer wall of the feeding pipe, a spring fixedly connected to the inner wall of the feeder housing, a baffle fixedly connected to the bottom of the spring, the top of the baffle fixedly connected to the other end of the wire rope, and the baffle slidably connected to the inner wall of the feeder housing.

[0018] Furthermore, a rotating wheel is rotatably connected to the inner wall of the feeder housing, and multiple feeding ports are provided on the inner wall of the feeder housing.

[0019] Using the above scheme, the baffle is pulled by the steel wire rope under the limit of the fixed seat to the inner wall of the feeder shell, so that the mixing chamber is connected to the inside of the feeder shell. When the feed feeding system inputs feed through the feeding chamber, the feed is driven by compressed air to reach the rotating wheel through the mixing chamber. The feed is fed from multiple directions through multiple feeding ports by the rotation of the rotating wheel, thereby improving the feed utilization rate.

[0020] Furthermore, the lifting and rotating assembly includes a support frame movably installed on the inner wall of the suspended gravity cage. Multiple rotating beads are movably installed on the inner wall of the support frame, and a lifting column is movably connected between the outer walls of the multiple rotating beads. The inner wall of the lifting column is fixedly connected to the outer wall of the feeding pipe, and an air outlet is provided on the outer wall of the lifting column.

[0021] Using the above solution, by installing freely rotatable ball bearings inside the support frame, the lifting column can rotate and rise within the support frame via the ball bearings.

[0022] Furthermore, an air supply assembly is rotatably connected to the inner wall of the air inlet. The air supply assembly includes an air supply pipe rotatably connected to the inner wall of the air inlet. A second movable plate is movably connected to the inner wall of the air supply pipe, and a guide plate is fixedly connected to the outer wall of the air supply pipe.

[0023] Furthermore, a swing assembly is provided at the end of the gas supply pipe away from the gas outlet. The swing assembly includes a swing frame, and an air inlet chamber is provided on the inner wall of the swing frame. The gas supply pipe is rotatably connected to the air inlet chamber in the swing frame, and a third movable plate is movably connected to the inner wall of the air inlet chamber.

[0024] Furthermore, the inner wall of the swing frame is rotatably connected with multiple swing blades, and the inner wall of the swing frame is also provided with a water accumulation cavity. The top of the water accumulation cavity is provided with a water inlet, and the bottom of the water accumulation cavity is provided with a drain outlet.

[0025] Using the above scheme, the lifting column rotates arbitrarily inside the support frame under the action of multiple rotating beads. When the water flow changes, the water flow drives the swing frame to rotate downstream of the water flow through the swing blades, placing the automatic feeder upstream of the water flow, thereby improving feed utilization. When the guide plate is in contact with the inner wall of the feeding pipe, compressed air does not flow through the air supply pipe, and water flows into the water accumulation chamber from the inlet, increasing the weight of the swing frame and causing it to sink. This causes the feeding pipe to sink, and as the swing frame sinks, it drives the air supply pipe to rotate. The guide plate then blocks the airflow in the air supply chamber, causing the compressed gas to be redirected to blow the second movable plate to rotate and be input into the air inlet chamber through the air supply pipe. The compressed gas then blows the third movable plate to block the water inlet, and the compressed gas squeezes the water in the water accumulation chamber and discharges it through the drain. When the water accumulation chamber is full of compressed gas, the weight of the swing frame decreases and it floats up, thereby driving the guide plate to reset. This process is repeated to improve the overall breeding efficiency.

[0026] Furthermore, a connecting rod is rotatably connected to the inner wall of the swing frame, and a support base is rotatably connected to the end of the connecting rod away from the swing frame. The inner wall of the support base is fixedly connected to the outer wall of the feeding pipe.

[0027] By adopting the above solution, the support base and the swing frame are connected by a connecting rod, which achieves the effect of strengthening and stabilizing.

[0028] Another aspect of this application provides a deep-sea aquaculture device, which further includes a ballast tank of an aquaculture vessel, a double-layered heat-insulating outer panel disposed around the ballast tank, a telescopic photovoltaic deck and a wind turbine power generation device disposed on the top of the ballast tank, and a flexible water intake hose disposed on the outer wall of the ballast tank. The ballast tank is also equipped with a feed feeding system and an oxygen-containing air compressor. The suspended gravity net cage is disposed below the ballast tank. The feeding chamber is connected to the feed feeding system on the ballast tank. The air supply chamber is connected to the oxygen-containing air compressor on the ballast tank.

[0029] The above scheme involves setting up a semi-enclosed aquaculture vessel with an open top and bottom. The upper half is insulated with a double-layered thermal insulation panel, and a ballast tank is located along the lower edge of the upper half to maintain the stability of the entire structure in the sea. The lower half is equipped with suspended gravity net cages, with the top edge of the net cages located at the top opening of the ballast tanks. A crane is available for net replacement, washing, and repair. Power is generated using a telescopic photovoltaic deck and a wind turbine generator, with a diesel generator and energy storage to ensure power supply. A high-flow, low-lift water pump is used to draw water from the seabed into the upper surface of the net cages via a flexible water intake hose. The seawater is then forced down to the lower opening to create a completely low-temperature environment for the aquaculture water, maintaining a temperature below 18°C ​​in summer.

[0030] The beneficial effects of this invention are:

[0031] 1. Compressed gas is supplied by an oxygen-containing air compressor and blown through the air delivery chamber to open the first movable plate. The first movable plate rotates and fits against the inner wall of the mixing chamber. At the same time, the steel wire rope is pulled, and under the limit of the fixed seat, the baffle is pulled against the inner wall of the feeder housing, so that the mixing chamber is connected to the inside of the feeder housing. When the feed feeding system inputs feed through the feeding chamber, the feed is driven by the compressed air to reach the rotating wheel through the mixing chamber. Through the rotation of the rotating wheel, the feed is fed in multiple directions through multiple feeding ports, thereby improving the feed utilization rate.

[0032] 2. By installing a swing frame connected to the feeding pipe on the reverse side of the automatic feeder, the swing frame has multiple freely rotating swing blades inside, and the lifting column fixedly connected to the feeding pipe can rotate freely inside the support frame under the action of multiple rotating balls. When the water flow changes, the water flow drives the swing frame to rotate to the downstream of the water flow through the swing blades, placing the automatic feeder upstream of the water flow, thereby improving the feed utilization rate.

[0033] 3. An air supply hole is set at the bottom of the lifting column. An air supply pipe rotates between the inner wall of the air supply hole and the inner wall of the air inlet chamber. A second movable plate and a guide plate are set at one end of the air supply pipe at the lifting column. When the guide plate is in contact with the inner wall of the feeding pipe, compressed air does not flow through the air supply pipe. Water flows into the water accumulation chamber from the water inlet, which increases the weight of the swing frame and causes it to sink. This causes the feeding pipe to sink. When the swing frame sinks, it drives the air supply pipe to rotate. The guide plate then blocks the airflow in the air supply chamber, causing the compressed gas to be redirected to blow the second movable plate to rotate and be input into the air inlet chamber through the air supply pipe. Then, it blows the third movable plate to block the water inlet. The compressed gas squeezes the water in the water accumulation chamber and discharges it through the drain. When the water accumulation chamber is full of compressed gas, the weight of the swing frame decreases and it floats up, thereby driving the guide plate to return to its original position. This process is repeated to improve the overall breeding efficiency. Attached Figure Description

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] Example 1, referring to Figure 2 , Figure 6 - Figure 10 The first embodiment of the present invention provides a semi-enclosed low-temperature controlled aquaculture cage, including a suspended gravity cage 5. A lifting and rotating assembly 7 is movably installed on the inner wall of the suspended gravity cage 5, and an oxygen supply and feeding mechanism 8 is provided inside the lifting and rotating assembly 7.

[0053] Reference Figure 6 The oxygen supply and feeding mechanism 8 includes a feeding component 81 fixedly connected to the inner wall of the lifting and rotating assembly 7. An automatic feeder 82 is fixedly connected to the end of the feeding component 81. The feeding component 81 includes a feeding pipe 811 fixedly connected to the inner wall of the lifting and rotating assembly 7. A partition 813 is fixedly connected to the inner wall of the feeding pipe 811. A feeding chamber 812 and an air delivery chamber 814 are respectively opened between the inner wall of the feeding pipe 811 and the two sides of the partition 813.

[0054] The air supply chamber 814 continuously supplies air and oxygen, while the feeding chamber 812 feeds the feed in a fixed amount at regular intervals. The feeding chamber 812 and the air supply chamber 814 are separated by a partition 813 in the feeding pipe 811, forming two channels to provide input channels for feeding and oxygen supply.

[0055] Reference Figure 7 - Figure 10 The inner wall of the feeding pipe 811 is rotatably connected to a first movable plate 815. The top of the first movable plate 815 overlaps with the bottom of the partition plate 813. The inner wall of the feeding pipe 811 is also provided with a mixing chamber 817, which is located below the air supply chamber 814. The opening of the first movable plate 815 is located between the air supply chamber 814 and the mixing chamber 817. The inner wall of the feeding pipe 811 is fixedly connected to a fixing seat 816. The outer wall of the fixing seat 816 overlaps with the inner wall of the first movable plate 815. The inner wall of the fixing seat 816 is slidably connected to a steel wire rope 818. One end of the steel wire rope 818 is fixedly connected to the inner wall of the first movable plate 815, and the steel wire rope 818 is slidably connected to the inner wall of the feeding pipe 811.

[0056] Specifically, the first movable plate 815 is located between the air supply chamber 814 and the mixing chamber 817, and has an opening below the air supply chamber 814. One end of the wire rope 818 passes through the feeding pipe 811 and the fixed seat 816 and is connected to the first movable plate 815, and extends and retracts due to the opening and closing of the first movable plate 815.

[0057] Compressed gas is supplied by an oxygen-containing air compressor and blown through the air delivery chamber 814 to open the first movable plate 815. The first movable plate 815 rotates and fits against the inner wall of the mixing chamber 817, while the steel wire rope 818 is pulled to control the opening and closing of the first movable plate 815.

[0058] Reference Figure 8 - Figure 10 The automatic feeder 82 includes a feeder housing 821 fixedly connected to the outer wall of the feeding pipe 811. A spring 824 is fixedly connected to the inner wall of the feeder housing 821. A baffle 825 is fixedly connected to the bottom of the spring 824. The top of the baffle 825 is fixedly connected to the other end of the wire rope 818. The baffle 825 is slidably connected to the inner wall of the feeder housing 821. A rotating wheel 823 is rotatably connected to the inner wall of the feeder housing 821. Multiple feeding ports 822 are opened on the inner wall of the feeder housing 821.

[0059] Specifically, the other end of the steel wire rope 818 is connected to the baffle 825 through the feeder housing 821 and the inside of the spring 824. The self-rotating wheel 823 is driven to rotate by compressed gas, so that compressed gas and feed can be evenly thrown out through multiple feeding ports 822. The feeding ports 822 are equipped with guardrails to prevent fish from accidentally entering.

[0060] By using a steel wire rope 818 to pull the baffle 825 along the inner wall of the feeder housing 821 under the limitation of the fixed seat 816, the mixing chamber 817 is connected to the inside of the feeder housing 821. When the feed feeding system inputs feed through the feeding chamber 812, the feed is driven by compressed air to reach the rotating wheel 823 through the mixing chamber 817. The feed is then fed from multiple directions through the rotation of the rotating wheel 823 via multiple feeding ports 822, thereby improving the feed utilization rate.

[0061] During use, an oxygen-containing air compressor continuously supplies air and oxygen to the air delivery chamber 814, while the feed feeding system feeds the feeding chamber 812 in a timed and quantitative manner. Compressed gas blows through the air delivery chamber 814 to open the first movable plate 815, causing it to rotate and fit against the inner wall of the mixing chamber 817. Simultaneously, the steel wire rope 818 is pulled, and under the limitation of the fixed seat 816, the baffle 825 is pulled against the inner wall of the feeder housing 821, making the mixing chamber 817 connected to the inside of the feeder housing 821. When the feed feeding system feeds through the feeding chamber 812, the feed, driven by the compressed air, passes through the mixing chamber 817 and reaches the rotating wheel 823. Through the rotation of the rotating wheel 823, the feed is fed from multiple directions through multiple feeding ports 822, thereby improving the feed utilization rate.

[0062] Example 2, refer to Figure 3 - Figure 5 , Figure 11 - Figure 15This is the second embodiment of the present invention, which differs from the first embodiment in that: referring to Figure 4 The lifting and rotating assembly 7 includes a support frame 71 that is movably installed on the inner wall of the suspended gravity net cage 5. Multiple rotating beads 73 are movably installed on the inner wall of the support frame 71. Lifting columns 72 are movably connected between the outer walls of the multiple rotating beads 73. The inner wall of the lifting column 72 is fixedly connected to the outer wall of the feeding pipe 811. An air outlet 74 is opened on the outer wall of the lifting column 72.

[0063] Specifically, the support frame 71 can be disassembled from the suspended gravity net box 5. The support frame 71 is equipped with a rotating ball 73 that can be rotated at will. The lifting column 72 can be rotated and raised in the support frame 71 through the rotating ball 73.

[0064] Reference Figure 12 An air supply assembly 83 is rotatably connected to the inner wall of the air outlet 74. The air supply assembly 83 includes an air supply pipe 831 rotatably connected to the inner wall of the air outlet 74. A second movable plate 832 is movably connected to the inner wall of the air supply pipe 831. A guide plate 833 is fixedly connected to the outer wall of the air supply pipe 831.

[0065] Reference Figure 13 A swing assembly 84 is provided at the end of the air supply pipe 831 away from the air outlet 74. The swing assembly 84 includes a swing frame 841. An air inlet chamber 842 is provided on the inner wall of the swing frame 841. The air supply pipe 831 is rotatably connected to the air inlet chamber 842 in the swing frame 841. A third movable plate 844 is movably connected to the inner wall of the air inlet chamber 842. Multiple swing blades 847 are rotatably connected to the inner wall of the swing frame 841. A water accumulation chamber 845 is also provided on the inner wall of the swing frame 841. A water inlet 843 is provided at the top of the water accumulation chamber 845. A drain outlet 846 is provided at the bottom of the water accumulation chamber 845.

[0066] Specifically, the gas supply pipe 831 connects the gas outlet 74 and the air inlet chamber 842, and can rotate a certain range within the gas outlet 74 and the air inlet chamber 842. The end of the gas supply pipe 831 located at the gas outlet 74 is connected to a second movable plate 832 and a guide plate 833. The second movable plate 832 can be opened by compressed gas, and the guide plate 833 can block the gas outlet chamber 814. The compressed gas in the air inlet chamber 842 can open the third movable plate 844. When the third movable plate 844 is open, it can block the water inlet 843. When the water accumulation chamber 845 is full of water, the weight of the swing frame 841 increases and it sinks. When the water accumulation chamber 845 is full of compressed gas, the weight of the swing frame 841 decreases and it floats.

[0067] The lifting column 72 rotates arbitrarily inside the support frame 71 under the action of multiple rotating balls 73. When the water flow changes, the water flow through the swing blade 847 drives the swing frame 841 to rotate to the downstream of the water flow, placing the automatic feeder 82 upstream of the water flow to improve feed utilization. When the guide plate 833 is in contact with the inner wall of the feeding pipe 811, compressed air does not flow through the air supply pipe 831, and water flows from the inlet 843 into the water accumulation chamber 845, increasing the weight of the swing frame 841 and causing it to sink, thereby driving the feeding pipe 811 to sink. When 41 sinks, it drives the air supply pipe 831 to rotate. The guide plate 833 then blocks the airflow in the air delivery chamber 814, causing the compressed gas to be redirected to blow the second movable plate 832 to rotate. The compressed gas is then input into the air intake chamber 842 through the air supply pipe 831. The third movable plate 844 is then blown to block the water inlet 843. The compressed gas squeezes the water in the water accumulation chamber 845 and discharges it through the drain outlet 846. When the water accumulation chamber 845 is filled with compressed gas, the weight of the swing frame 841 is reduced and it floats up, thereby driving the guide plate 833 to reset. This process is repeated to improve the overall breeding efficiency.

[0068] Reference Figure 5 The inner wall of the rocking frame 841 is also rotatably connected to a connecting rod 85. The end of the connecting rod 85 away from the rocking frame 841 is rotatably connected to a support seat 86. The inner wall of the support seat 86 is fixedly connected to the outer wall of the feeding pipe 811.

[0069] Specifically, the support base 86 is connected to the swing frame 841 by the connecting rod 85, which has the effect of strengthening and stabilizing.

[0070] During use, a swing frame 841 connected to the feeding pipe 811 is installed on the reverse side of the automatic feeder 82. The swing frame 841 contains multiple freely rotatable swing blades 847. The lifting column 72, fixedly connected to the feeding pipe 811, can rotate freely inside the support frame 71 under the action of multiple rotating balls 73. When the water flow changes, the water flow through the swing blades 847 drives the swing frame 841 to rotate downstream, placing the automatic feeder 82 upstream, thus improving feed utilization. An air outlet 74 is installed at the bottom of the lifting column 72. An air supply pipe 831 rotates between the inner wall of the air outlet 74 and the inner wall of the air inlet chamber 842. A second movable plate 832 and a guide plate 833 are installed at one end of the air supply pipe 831 at the lifting column 72. When the guide plate 833... When the 3rd element is in contact with the inner wall of the feeding pipe 811, compressed air does not circulate in the air supply pipe 831. Water flows from the inlet 843 into the water accumulation chamber 845, increasing the weight of the swaying frame 841 and causing it to sink. This sinks the feeding pipe 811, and as the swaying frame 841 sinks, it rotates the air supply pipe 831. The guide plate 833 then blocks the airflow in the air delivery chamber 814, causing the compressed gas to be redirected and blown to rotate the second movable plate 832. The compressed gas is then input into the air intake chamber 842 through the air supply pipe 831, and then blows to the third movable plate 844 to block the water inlet 843. The compressed gas squeezes the water in the water accumulation chamber 845 and discharges it through the drain 846. When the water accumulation chamber 845 is filled with compressed gas, the weight of the swaying frame 841 decreases, causing it to float upwards, thereby resetting the guide plate 833. This process is repeated to improve the overall breeding efficiency. The remaining structure is the same as in Example 1.

[0073] Working principle of the invention:

[0074] The aquaculture vessel is semi-enclosed, with both the upper and lower sections open. The upper section is insulated with a double-layered heat-insulating outer panel 2. A ballast tank 1 is located along the lower edge of the upper section to maintain the stability of the entire structure in the sea. A suspended gravity net cage 5 is installed in the lower section, with the top edge of the net cage located at the top opening of the ballast tank 1. A crane is available for net replacement, washing, and repair. Power is generated using a telescopic photovoltaic deck 3 and a wind turbine generator 4. A diesel generator and energy storage are also provided to ensure power supply. Water is pumped from the seabed into the upper surface of the net cage via a flexible water intake hose 6 using a high-flow, low-lift water pump. The seawater is pushed down to the lower opening to create a completely low-temperature environment for the aquaculture water, maintaining a temperature below 18°C ​​in summer.

[0075] An oxygen-containing air compressor continuously supplies air and oxygen to the air delivery chamber 814, while a feed feeding system feeds the feeding chamber 812 in a timed and quantitative manner. Compressed gas blows through the air delivery chamber 814 to open the first movable plate 815, causing it to rotate and fit against the inner wall of the mixing chamber 817. Simultaneously, the steel wire rope 818 is pulled, and under the limitation of the fixed seat 816, the baffle 825 is pulled against the inner wall of the feeder housing 821, making the mixing chamber 817 connected to the inside of the feeder housing 821. When the feed feeding system feeds through the feeding chamber 812, the feed, driven by the compressed air, passes through the mixing chamber 817 and reaches the rotating wheel 823. Through the rotation of the rotating wheel 823, the feed is fed from multiple directions through multiple feeding ports 822, thereby improving the feed utilization rate.

[0076] A swing frame 841 connected to the feeding pipe 811 is provided on the reverse side of the automatic feeder 82. The swing frame 841 has multiple freely rotatable swing blades 847 inside. The lifting column 72, which is fixedly connected to the feeding pipe 811, can rotate freely inside the support frame 71 under the action of multiple rotating balls 73. When the water flow changes, the water flow through the swing blades 847 drives the swing frame 841 to rotate to the downstream of the water flow, placing the automatic feeder 82 upstream of the water flow, thereby improving the feed utilization rate.

[0077] An air outlet 74 is provided at the bottom of the lifting column 72. An air supply pipe 831 is rotatably connected between the inner wall of the air outlet 74 and the inner wall of the air inlet chamber 842. A second movable plate 832 and a guide plate 833 are provided at one end of the air supply pipe 831 on the lifting column 72. When the guide plate 833 is in contact with the inner wall of the feeding pipe 811, compressed air does not flow through the air supply pipe 831. Water flows from the water inlet 843 into the water accumulation chamber 845, which increases the gravity of the swing frame 841 and causes it to sink, thereby driving the feeding pipe 811 to sink.

[0078] When the swing frame 841 sinks, it drives the air supply pipe 831 to rotate. The guide plate 833 then blocks the airflow in the air delivery chamber 814, causing the compressed gas to be redirected to blow the second movable plate 832 to rotate. The compressed gas is then input into the air intake chamber 842 through the air supply pipe 831. The third movable plate 844 is then blown to block the water inlet 843. The compressed gas squeezes the water in the water accumulation chamber 845 and discharges it through the drain outlet 846. When the water accumulation chamber 845 is filled with compressed gas, the weight of the swing frame 841 is reduced and it floats up, thereby driving the guide plate 833 to reset. This process is repeated to improve the overall breeding efficiency.
