Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture, and more specifically, to a net cage for deep-sea aquaculture. Background Technology

[0002] With the gradual saturation of coastal waters and the gradual deterioration of the aquaculture environment, near-shore aquaculture can no longer meet the needs of aquaculture. Therefore, most fishermen are turning their attention to the broader open sea areas. In order to adapt to the hydrological environment of the open sea areas, large aquaculture cages have gradually become a preferred aquaculture tool for fishermen. The application of large aquaculture cages in the open sea areas has broad prospects and huge potential. Through continuous optimization of design and improvement of management level, large aquaculture cages will create more economic and social benefits for fishermen.

[0003] In deep-sea aquaculture, feeding fish is a crucial step. However, traditional net cages often encounter a problem when feeding: fish food tends to accumulate at the edge of the net cage, making it difficult to spread quickly and evenly inside. This phenomenon not only intensifies competition among fish at the edge, preventing some fish from obtaining enough food, but also causes a large amount of fish food to be washed away from the net cage by seawater and eventually float in the sea, resulting in serious waste. To address this, we propose a new type of net cage for deep-sea aquaculture. Summary of the Invention

[0004] This invention provides a deep-sea aquaculture cage that solves the technical problem in related technologies where fish food tends to accumulate at the edge of the cage, causing a large amount of fish food to be carried away from the cage by the scouring and flow of seawater.

[0005] The present invention provides a deep-sea aquaculture cage, comprising: a cage floating plate, wherein a plurality of wave-following energy storage mechanisms are arranged in different directions on the side of the cage floating plate near the sea surface;

[0006] The wave-following energy storage mechanism includes several floating balls, wave generators and air storage devices. The floating balls are connected in series by ropes, and each floating ball corresponds to an air storage device. The air storage device includes a turbofan component. The floating balls drive the turbofan component to rotate by rising and falling with the waves, and pump air into the connected wave generator.

[0007] The wave generator consists of two pressure chambers with different volumes, namely pressure chamber one and pressure chamber two. When the air pressure increases to a preset value, the two chambers release high-pressure gas instantaneously at different times to form an air explosion, which rushes towards the center of the net cage, causing the sea surface waves to float towards the center and impacting the fish food to spread into the net.

[0008] Furthermore, a deep-sea net is installed below the floating plate of the net cage, and several net-supporting posts are installed on the inner side of the deep-sea net to support the deep-sea net. The bottom of the net cage bottom plate is fixedly installed at the bottom of the net cage bottom plate, and a counterweight box is fixedly installed below the net cage bottom plate.

[0009] Furthermore, the wave-following energy storage mechanism also includes a wave-following box, which is fixedly connected to the floating plate of the net cage. Several interconnected floating balls are also fixedly connected to the inner wall of the wave-following box by ropes. At the same time, the ropes of the interconnected floating balls are in a slack state, so as to rise and fall with the waves on the sea surface. Each of the floating balls is filled with liquid less than half of its space for counterweight.

[0010] Furthermore, a limiting sleeve is fixedly installed at the center of the upper wall of each floating ball, and a rotating ball is installed inside the limiting sleeve. A lifting column is fixedly installed above the rotating ball, and the lifting column floats up and down with the floating ball through the rotating ball and the limiting sleeve.

[0011] Furthermore, the gas storage device also includes an energy storage cylinder, which is fixed to the upper wall of the follower box. An inner cylinder is fixedly installed inside the energy storage cylinder, and several air outlets are opened at the bottom of the inner cylinder. A closing plate is rotatably installed at the output end of the air outlet. The space between the energy storage cylinder and the inner cylinder is divided into two independent spaces, namely a drainage chamber and an exhaust chamber. The output end of the exhaust chamber is connected to an air supply auxiliary pipe, and the drainage chamber has several drainage holes.

[0012] Furthermore, a partition plate is fixedly installed on the top of the inner cylinder, and a drainage plate is fixedly installed on the partition plate. The partition plate and the drainage plate divide the top gap of the inner cylinder into two spaces. The partition plate and the drainage plate are also provided with round holes for air to enter. One side of the drainage plate is connected to the drainage chamber. The upper wall of the energy storage cylinder is also provided with round holes.

[0013] Furthermore, the turbofan component is installed in the inner cylinder, and a threaded post is inserted through the center of the turbofan component, and the threaded post is threadedly connected to the turbofan component. Several elastic bands are fixedly installed on the upper wall of the turbofan component, and the end of the elastic band away from the turbofan component is fixedly connected to the lower wall of the partition plate. A bearing is rotatably installed below the turbofan component, and the bearing is fixedly connected to the top of the lifting column.

[0014] Furthermore, the wave-generating component also includes an energy-spraying box, with the jetting end of the energy-spraying box facing the center of the net cage floating plate. A water-slapping plate is rotatably mounted on the jetting end of the energy-spraying box, and a reset pull belt is fixedly mounted inside the water-slapping plate. A winding wheel is fixedly mounted on the end of the reset pull belt away from the water-slapping plate, and the reset pull belt is wound around the winding wheel. The winding wheel is rotatably mounted on the inner wall of the energy-spraying box.

[0015] Furthermore, an impact box is fixedly installed inside the energy injection box. Both the first and second impact chambers are fixed in the impact box. The air inlet ends of the first and second impact chambers are provided with a main air supply pipe, which is connected to the auxiliary air supply pipe. The air outlet end of the impact box is provided with a trumpet-shaped external nozzle.

[0016] Furthermore, a sealing cover is rotatably installed at the air outlet end of the second stamping chamber. A clamping head is fixedly installed at the end of the sealing cover away from the rotating shaft. A retraction groove is opened on the side of the second stamping chamber near the clamping head. A blocking head is movably installed in the retraction groove. A spring is fixedly installed at the bottom end of the blocking head. An expansion air bladder is connected to the outer wall of the second stamping chamber and communicates with it. A side groove is opened at the end of the second stamping chamber near the expansion air bladder. An arc-shaped spring is fixedly installed in the side groove. A pull rope is fixedly installed on the spring. The other end of the pull rope is fixedly connected to the blocking head.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention cleverly utilizes the natural wave energy of the ocean by designing a wave-following energy storage mechanism. The floating ball rises and falls with the waves, driving the turbine component to rotate, which in turn pumps air into the wave generator. This process does not require an external power source, achieving efficient energy utilization. At the same time, the two pressure chambers with different volumes inside the wave generator can release high-pressure gas instantaneously at different times when the air pressure increases to a preset value, forming an air explosion. This design not only enhances the impact force of the waves, but also allows the waves to rush more evenly towards the center of the net cage, effectively promoting the diffusion of fish food into the net. The entire process is automated, reducing human intervention and improving aquaculture efficiency.

[0019] The wave-following energy storage mechanism and wave-generating components not only provide a more dynamic living environment for the fish, but also enhance their activity through the continuous generation of waves. Driven by the waves, the fish need to swim constantly to maintain stability, which helps promote their healthy growth. At the same time, the impact of the waves can also make the fish food more evenly distributed in the net cage, reducing the competitive pressure caused by the fish competing for food. All of these factors help improve the quality of aquaculture, making the fish stronger and the meat more delicious. Attached Figure Description

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a deep-sea aquaculture cage includes: a cage floating plate 11, on which a plurality of wave-following energy storage mechanisms 2 are arranged in different directions on the side of the cage floating plate 11 near the sea surface.

[0033] The wave generator includes two pressure chambers with different spatial volumes, namely pressure chamber one 37 and pressure chamber two 38. When the air pressure increases to a preset value, the two chambers release high-pressure gas instantaneously at different times to form an air explosion, which rushes towards the center of the net cage, causing the sea surface waves to float towards the center and impacting the fish food to spread into the net.

[0034] A deep-sea net 13 is provided below the floating plate 11 of the net cage, and several net support posts 12 for supporting the deep-sea net 13 are provided on the inner side of the deep-sea net 13.

[0035] The wave-following energy storage mechanism 2 also includes a wave-following box 21, which is fixedly connected to the net cage floating plate 11.

[0036] Each floating ball 22 has a fixed limiting sleeve 23 at the center of its upper wall. A rotating ball 24 is rotatably installed inside the limiting sleeve 23. A lifting column 25 is fixedly installed above the rotating ball 24. The lifting column 25 floats up and down with the floating ball 22 through the rotating ball 24 and the limiting sleeve 23.

The upper wall of the energy storage cylinder 41 is also provided with round holes.

[0039] like Figure 5 , Figure 6 and Figure 7 As shown, the turbofan component 44 is disposed in the inner cylinder 43. A threaded post 46 is provided through the center of the turbofan component 44, and the threaded post 46 is threadedly connected to the turbofan component 44. Several elastic bands 45 are fixedly provided on the upper wall of the turbofan component 44.

A bearing 402 is rotatably provided below the turbofan component 44, and the bearing 402 is fixedly connected to the top end of the lifting column 25.

[0040] The wave-generating component also includes an energy-spraying box 31, with the jetting end of the energy-spraying box 31 facing the center of the net cage floating plate 11. A water-slapping plate 32 is rotatably mounted on the jetting end of the energy-spraying box 31. A reset pull belt 34 is fixedly mounted inside the water-slapping plate 32. A winding wheel 35 is fixedly mounted on the end of the reset pull belt 34 away from the water-slapping plate 32. The reset pull belt 34 is wound around the winding wheel 35. The winding wheel 35 is rotatably mounted on the inner wall of the energy-spraying box 31.

[0041] like Figure 8 and Figure 9 As shown, an impact box 36 is fixedly installed inside the energy injection box 31. The first impact chamber 37 and the second impact chamber 38 are both fixed in the impact box 36. The air inlet ends of the first impact chamber 37 and the second impact chamber 38 are provided with an air supply main pipe 33. The air supply main pipe 33 is connected to the air supply auxiliary pipe 42. The air outlet end of the impact box 36 is provided with a trumpet-shaped external nozzle 302.

[0042] A sealing cover 301 is rotatably installed at the air outlet end of the second stamping chamber 38. A locking head 303 is fixedly installed at the end of the sealing cover 301 away from the rotating shaft. A retraction groove 304 is opened on the side of the second stamping chamber 38 near the locking head 303. A blocking head 306 is movably installed in the retraction groove 304. A spring 305 is fixedly installed at the bottom end of the blocking head 306. An expansion air bladder 39 is connected to the outer wall of the second stamping chamber 38 and communicates with it. A side groove 309 is opened at the end of the second stamping chamber 38 near the expansion air bladder 39. An arc-shaped spring piece 307 is fixedly installed in the side groove 309. A pull rope 308 is fixedly installed on the spring piece 307. The other end of the pull rope 308 is fixedly connected to the blocking head 306.

[0043] First, when the staff poured fish food into the deep-sea net 13, the fish food could only be poured onto the edge of the deep-sea net 13;

[0044] As the sea surface fluctuates, several floating balls 22 rise and fall with the waves. As long as there are waves on the sea surface, the floating balls 22 will fluctuate accordingly. Each time the floating balls 22 rise with the waves, they will push the lifting column 25, which in turn pushes the bearing 402. The bearing 402 applies upward thrust to the turbofan component 44, thereby driving the turbofan component 44 to rotate upward along the thread of the threaded column 46. As the turbofan component 44 rises, air passes through the partition plate 47 and enters the inner cylinder 43 through multiple round holes. At this time, the seawater entering through the round holes will flow into the drainage chamber and then be discharged through the holes to prevent seawater from entering the inner cylinder 43.

[0045] As the floating ball 22 descends with the waves, it pulls the lifting column 25 down, which in turn pulls the bearing 402 down. The bearing 402 then applies a downward pulling force to the turbofan component 44, causing it to rotate downwards. The downward rotation of the turbofan component 44 blows air downwards, allowing it to enter the exhaust chamber through several air outlets 49. The air then flows into the main air supply pipe 33 through the secondary air supply pipe 42, and finally gradually converges into the first ramming chamber 37 and the second ramming chamber 38.

[0046] When the turbofan component 44 descends, the elastic band 45 will be stretched and wrapped around the threaded column 46. Then, when the turbofan component 44 rises, the elastic band 45 can apply a pulling force. When the turbofan component 44 rises, several closing plates 401 close several air outlets 49.

[0047] As the air pressure in the second pressurization chamber 38 gradually increases, some of the air in the second pressurization chamber 38 will flow into the expansion airbag 39, causing the expansion airbag 39 to gradually expand. When the expansion airbag 39 expands to the preset volume, the expansion airbag 39 will be squeezed into the side groove 309. With the compression of the spring 307, the pull rope 308 is pulled. The pull rope 308 is S-shaped. The pull rope 308 pulls the blocking head 306 back into the retraction groove 304, instantly releasing the obstruction to the blocking head 303. At this time, the high-pressure gas in the second pressurization chamber 38 is released instantly, and the instantaneous release of high-pressure gas forms a gas explosion, which is ejected from the outer nozzle 302, causing waves to form on the sea surface, spreading the fish food into the deep-sea net 13, and also preventing the fish food from floating out of the deep-sea net 13.

[0048] All the structures of the first stamping chamber 37 are the same as those of the second stamping chamber 38, except for the volume. The instantaneous release of air pressure in the first stamping chamber 37 also plays the role of air explosion. The air explosion impact force of the first stamping chamber 37 is small, but the frequency is fast.

[0049] When the splashing plate 32 is impacted by the first pressure chamber 37 and the second pressure chamber 38, the splashing plate 32 will rotate. Then, through the winding force of the winding wheel 35 on the reset pull belt 34, the splashing plate 32 will be driven to quickly reset. When the splashing plate 32 rotates out, it will lift the seawater upward to create waves. When the splashing plate 32 resets, it can press the seawater downward to promote the rapid spread of waves towards the center.

[0050] After each time the sealing cap 301 is rotated out, the air pressure is released, and the sealing cap 301 resets under gravity.

[0051] The working steps of this invention are as follows:

[0052] Step 1: Pour the fish food

[0053] Workers poured fish food onto the edge of the deep-sea net 13 to ensure that the fish food was evenly distributed along the edge of the deep-sea net 13, providing a basis for the subsequent wave diffusion of the fish food.

[0054] Step 2: Floating ball 22 rises and falls with the waves

[0055] As the sea surface fluctuates, the floating ball 22 moves up and down with the waves, pushing the lifting column 25 and the bearing 402, which in turn drives the turbofan component 44 to rotate. By utilizing the natural wave energy of the sea surface, the rotation of the turbofan component 44 can be achieved without an external power source, thus realizing the efficient use of energy.

[0056] Step 3: Turbofan component 44 drives airflow

[0057] When the turbofan component 44 rotates, it sends air into the exhaust chamber through the outlet 49, and then flows into the main air supply pipe 33 through the secondary air supply pipe 42, and finally gathers into the first ramming chamber 37 and the second ramming chamber 38. The rotation of the turbofan component 44 not only realizes the effective collection of air, but also provides a power source for subsequent wave generation.

[0058] Step 4: Pressure Increase and Release in the Compression Chamber

[0059] As the air pressure in the pressurization chamber gradually increases, the inflatable airbag 39 expands and squeezes the spring 307. The pull rope 308 pulls the stopper head 306 to retract, instantly releasing high-pressure gas to form a gas explosion. Through the gradual increase and instantaneous release of air pressure, the gas explosion effect is achieved, providing powerful power for wave generation.

[0060] Step 5: Wave generation and resetting of the water-splashing plate 32

[0061] When the pressure chamber releases high-pressure gas, it pushes the water-splashing plate 32 to rotate. Then, the winding force of the winding wheel 35 causes the water-splashing plate 32 to quickly return to its original position, thus creating waves. The rotation and return of the water-splashing plate 32 not only enhances the formation of waves but also promotes the diffusion of waves towards the center, which helps to distribute the fish food evenly.

[0062] Step Six: Reset the sealing cap 301

[0063] After each pressure release, the sealing cover 301 resets under gravity to prepare for the next gas explosion. The reset of the sealing cover 301 ensures the sealing of the pressurization chamber and provides a guarantee for subsequent pressure increases and releases.

[0064] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
