[0002] Yellow croaker is a mid- and lower-level migratory economic fish species unique to the southeastern coast of my country. my country began to study artificial breeding and aquaculture technology for yellow croaker in 1985, and realized aquaculture industrialization in 2000. In recent years, my country has vigorously promoted the development of deep-sea aquaculture, and deep-sea aquaculture equipment and facilities such as gravity deep-water cages, engineered fences, truss cages and aquaculture vessels have been put into use for the aquaculture of high-quality yellow croaker.

[0003] The deep-sea aquaculture cages for yellow croaker are mainly composed of cage frame structures, net bags or net covers, buoy systems, anchoring systems and aquaculture platforms. During the aquaculture process, the feed and excrement produced by yellow croaker often accumulate in the cages, and the residual bait and feces often clog the mesh, seriously affecting the water exchange inside and outside the cages, resulting in the deterioration of aquaculture water quality and frequent diseases, which seriously affects the production and economic benefits of yellow croaker aquaculture. Traditional daily aquaculture management mostly relies on manual or specific equipment to clean up the waste in the cages.

[0012] Furthermore, a plurality of cavities are provided at the bottom of the dredging plate, and a push plate is slidably connected to the inside of the cavity through a second spring seal.

[0015] Furthermore, a filter screen is fixedly installed in the liquid outlet hole.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. A deep-sea aquaculture net cage for large yellow croaker described in the present invention moves the storage frame with the servo motor, and the residual bait and feces in the box will enter the slot and accumulate on the filter frame, thereby completing the collection of the residual bait and feces. When the storage frame moves to the end of the aquaculture net cage body, the storage frame is lifted by the first electric push rod, so that the seawater in the slot of the storage frame flows back into the sea through the filter frame, and the residual bait and feces are blocked by the filter frame and remain in the slot of the storage frame. The designed mechanism realizes the function of quickly cleaning the impurities on the sea surface in the aquaculture net cage body, and the impurities on the sea surface are quickly salvaged by the cooperation of the slot of the storage frame and the filter frame, thereby reducing the residual feces of large yellow croaker in the box, and also cleaning the unused feed, avoiding the unused feed from causing eutrophication of water quality, and then making the water quality in the aquaculture net cage body meet the growth environment of large yellow croaker. The multi-stage telescopic tube installed at the same time also protects the screw rod, reducing the probability of screw rod replacement and maintenance. Moreover, this design can be quickly installed and disassembled. When it comes to aquaculture cages of different sizes, you only need to match the screw rod of the appropriate length to use it, so that it can adapt to more application scenarios and is also easy to promote and use.

[0018] 2. A deep-sea aquaculture cage for large yellow croaker described in the present invention is moved in a direction away from the storage tank by the second electric push rod with the extension plate, so that one side of the extension plate is always in contact with the inner wall of the aquaculture cage body, and the roller is used to contact with the inner wall of the aquaculture cage body to reduce friction and facilitate movement. At the same time, the roller installed allows a gap between the inner wall of the aquaculture cage body and the sensor, thereby effectively preventing the sensor from being damaged by friction on the inner wall of the aquaculture cage body, and protecting the sensor. At the same time, the arc-shaped extension plate can push impurities on the sea surface forward, effectively reducing the flow of impurities through the gap. The installed partition and sealing ring can effectively prevent seawater from entering the storage tank, thereby ensuring the normal operation of the storage tank components. When the storage frame brings the second electric push rod and the extension plate close to the end of the aquaculture cage body, the second electric push rod moves the extension plate to the storage frame to reset, and at this time, the arc-shaped extension plate brings the impurities to the storage frame, assisting the impurities to enter the notch for collection. The above-designed mechanism can effectively clean impurities in the aquaculture cage body, and the second electric push rod and the extension plate are highly fitted to the inner wall of the aquaculture cage body, which greatly improves the cleaning efficiency.

[0019] 3. The large yellow croaker deep-sea aquaculture cage described in the present invention uses the second electric push rod to continue to drive the extension plate and the fixed plate to move excessively. The extension plate continues to drive the impurities to approach the notch. At this time, the fixed plate will squeeze the elastic block on the bottom bracket. The fixed plate is designed to be "T"-shaped to reduce the lateral deformation of the elastic block, thereby more efficiently squeezing the elastic block. The top and bottom of the elastic block are not sealed to leave space for deformation, thereby avoiding the situation of being squeezed and ruptured due to lack of deformation space. After the elastic block is squeezed, the gas is quickly filled into the air outlet through the outlet pipe and the end cover is rotated to open. The blown gas will assist the extension plate to blow the impurities to the notch, thereby completing the efficient collection and cleaning of impurities on the sea surface in the aquaculture cage body. After the extrusion is completed, the second electric push rod resets the fixed plate and the extension plate, so that the elastic block is no longer squeezed.

[0020] 4. The deep-sea aquaculture cage for large yellow croaker described in the present invention moves with the second electric push rod when the extension plate is moved. When the second magnetic block is close to the first magnetic block, the first magnetic block on the slide bar and the second magnetic block will repel each other, thereby sliding and compressing the first spring, and moving the dredging plate in a direction away from the storage slot. When the dredging plate moves, it will continuously drive the impact ball to hit the holes of the filter frame, thereby generating vibrations, and compacting the impurities on the filter net, thereby achieving the purpose of loading more impurities. At the same time, the continuous impact on the holes of the filter frame can also keep it unobstructed, thereby ensuring the subsequent outflow of seawater. Since the aquaculture cage body is cylindrical, when the storage frame moves, the extension plate will continuously slide, contract and extend, thereby keeping the impact ball efficiently hitting the filter frame, achieving efficient loading and dredging.

[0021] 5. In the deep-sea aquaculture cage for large yellow croaker described in the present invention, when the second electric push rod with the extension plate is continuously sliding, contracting and extending, the second electric push rod will also continuously squeeze the loading box with the fixing plate, so that the disinfectant in the loading box is quickly filled into the connecting pipe, and flows into the seawater of the aquaculture cage body through the liquid outlet hole and the filter screen of the connecting pipe. By spraying the disinfectant, pathogenic microorganisms such as bacteria, viruses, fungi, etc. in the environment inside and outside the aquaculture cage body can be killed, reducing the risk of fish infection and allowing large yellow croaker seedlings to grow better.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figures 1 to 9As shown, a large yellow croaker deep-sea aquaculture cage according to an embodiment of the present invention comprises an aquaculture cage body 1, and a plurality of pull ropes 2 are fixedly installed around the aquaculture cage body 1; a collecting device 10 is arranged on the top of the aquaculture cage body 1, and the collecting device 10 comprises a base 11 and a support plate 14 fixedly installed on the top of the aquaculture cage body 1, a servo motor 12 is fixedly installed on the top of the base 11, a screw rod 13 is fixedly installed on the output end of the servo motor 12, and one end of the screw rod 13 away from the servo motor 12 is connected to the support plate 14; a sleeve frame 15 is movably connected to the surface of the screw rod 13, a fixing frame 16 is fixedly installed on the bottom of the sleeve frame 15, a first electric push rod 17 is fixedly installed in the fixing frame 16, a storage frame 18 is fixedly installed on the output end of the first electric push rod 17, a notch 19 is opened on one side of the storage frame 18, and a filter frame 20 is fixedly installed in the notch 19.

[0042] Specifically, two multi-stage telescopic tubes 70 are sleeved on the surface of the screw rod 13, and the two multi-stage telescopic tubes 70 are respectively arranged on both sides of the sleeve frame 15, one end of the two multi-stage telescopic tubes 70 is fixedly connected to the sleeve frame 15, one end of one multi-stage telescopic tube 70 away from the sleeve frame 15 is fixedly connected to the servo motor 12, and the other end of the multi-stage telescopic tube 70 away from the sleeve frame 15 is fixedly connected to the support plate 14, and the multi-stage telescopic tube 70 is composed of a plurality of hollow round tubes slidably connected.

[0043] During operation, when there is a large amount of feces discharged by large yellow croaker, unused feed or other impurities on the sea surface in the breeding cage body 1, the servo motor 12 on the base 11 is started, and the servo motor 12 and the screw rod 13 are used to move the sleeve frame 15, and the fixed frame 16, the first electric push rod 17 and the storage frame 18 at the bottom of the sleeve frame 15 will move with it.

[0044] The first electric push rod 17 in the fixed frame 16 is used to lift the storage frame 18, so that the notch 19 of the storage frame 18 is partially below the sea surface, while the rest is on the sea surface. As the servo motor 12 moves the storage frame 18, the impurities on the sea surface will enter the notch 19 and accumulate on the filter frame 20, thereby completing the collection of impurities floating on the sea surface. When the storage frame 18 moves to the end of the aquaculture cage body 1, the storage frame 18 is lifted by the first electric push rod 17, so that the seawater in the notch 19 of the storage frame 18 flows back into the sea through the filter frame 20, while the impurities are blocked by the filter frame 20 and remain in the notch 19 of the storage frame 18. At the same time, using the first electric push rod 17 to lift the storage frame 18 also facilitates subsequent staff to take out the collected impurities, thereby facilitating the reuse of the storage frame 18.

[0045] Since the aquaculture cage body 1 is exposed to the sea for a long time, the multi-stage telescopic tube 70 can be installed to protect the screw rod 13 and effectively reduce the impact of seawater and harsh environment on the screw rod 13.

[0046] The mechanism designed above can realize the function of quickly cleaning the residual bait and feces in the breeding net box body 1. The residual bait and feces in the box are quickly salvaged by the cooperation of the notch 19 of the storage frame 18 and the filter frame 20, thereby reducing the residue of large yellow croaker feces. It also cleans up the unused feed to avoid eutrophication of water quality caused by unused feed, thereby making the water quality in the breeding net box body 1 meet the growth environment of large yellow croaker. The multi-stage telescopic tube 70 installed at the same time also protects the screw rod 13, reducing the probability of replacement and maintenance of the screw rod 13. And this design can realize fast installation and disassembly. When it is used for breeding net boxes 1 of different sizes, it only needs to match the screw rod 13 of the appropriate length, so that it can adapt to more application scenarios and is also convenient for promotion and use.

[0047] Two extension mechanisms 30 are arranged in the storage frame 18, and the two extension mechanisms 30 are symmetrically distributed about the central axis of the storage frame 18. The extension mechanism 30 includes a storage groove 31 opened on one side of the storage frame 18, and a second electric push rod 32 is fixedly installed in the storage groove 31. An extension plate 33 is fixedly installed at the output end of the second electric push rod 32, and a side of the extension plate 33 away from the second electric push rod 32 is arc-shaped, and a sensor 34 is fixedly installed on the arc-shaped surface of the extension plate 33.

[0048] Specifically, the arc surface of the extension plate 33 is rotatably connected to a plurality of rollers 35 made of rubber material, and the surface of the rollers 35 is in contact with the inner wall of the aquaculture cage body 1. A partition 40 is fixedly installed in the storage slot 31, and the output end of the second electric push rod 32 and the extension plate 33 both pass through the partition 40. A sealing ring is fixedly arranged between the partition 40 and the output end of the electric push rod, and a sealing ring is arranged between the partition 40 and the extension plate 33.

[0049] When the storage frame 18 moves in the aquaculture net box body 1, it will move with the second electric push rods 32 and the extension plate 33 on both sides. The second electric push rod 32 monitors the sensor 34 so that the roller 35 at one end of the extension plate 33 always fits with the inner wall of the aquaculture net box body 1. Since the aquaculture net box body 1 is cylindrical, as the storage frame 18 moves, the second electric push rod 32 will move the extension plate 33 away from the storage slot 31, so that one side of the extension plate 33 always fits with the inner wall of the aquaculture net box body 1. The roller 35 fits with the inner wall of the aquaculture net box body 1 to reduce friction and facilitate movement. The roller 35 installed at the same time makes a gap between the inner wall of the aquaculture net box body 1 and the sensor 34, thereby effectively preventing the friction of the inner wall of the aquaculture net box body 1 from damaging the sensor 34, and protecting the sensor 34. At the same time, the arc-shaped extension plate 33 can push impurities on the sea surface to the front, effectively reducing the flow of residual bait and feces through the gap. The installed partition 40 and sealing ring can effectively prevent seawater from entering the storage tank 31, thereby ensuring the normal operation of the storage tank 31 components. When the storage frame 18 brings the second electric push rod 32 and the extension plate 33 close to the end of the aquaculture cage body 1, the second electric push rod 32 brings the extension plate 33 to move to the storage frame 18 to reset. At this time, the arc-shaped extension plate 33 brings the impurities to the storage frame 18, and assists the impurities to enter the slot 19 for collection. The above-designed mechanism achieves the effect of efficiently cleaning the residual bait and feces in the aquaculture cage body 1, and the second electric push rod 32 and the extension plate 33 are highly fitted to the inner wall of the aquaculture cage body 1, which greatly improves the cleaning efficiency.

[0050] A blowing mechanism 50 is provided on the second electric push rod 32, and the blowing mechanism 50 includes a "T"-shaped fixing plate 51 fixedly installed on the output end of the second electric push rod 32, a base 52 is fixedly installed in the storage groove 31, a hollow elastic block 54 is fixedly installed on one side of the base 52, an air inlet pipe and an air outlet pipe 53 connected to the interior are fixedly installed at one end of the elastic block 54, and a one-way valve is provided in the air inlet pipe and the air outlet pipe 53, and a plurality of air outlet holes 55 are opened on the arc surface of the extension plate 33, and one end of the air outlet pipe 53 away from the elastic block 54 is connected to the air outlet hole 55, and an end cover is rotatably connected to the air outlet hole 55 through a torsion spring.

[0051] During operation, when the extension plate 33 returns to the slot 19 of the storage frame 18 with the impurities, the extension plate 33 moves to the initial position and stops. At this time, the second electric push rod 32 is used to continue to drive the extension plate 33 and the fixed plate 51 to move excessively. The extension plate 33 continues to drive the impurities to approach the slot 19. At this time, the fixed plate 51 will squeeze the elastic block 54 on the bottom bracket 52. The fixed plate 51 is designed to be "T" shaped to reduce the lateral deformation of the elastic block 54, thereby squeezing the elastic block 54 more efficiently. The top and bottom of the elastic block 54 are not sealed to leave space for deformation, so as to avoid being squeezed and broken due to lack of deformation space. After being squeezed in the elastic block 54, the gas is quickly filled into the outlet hole 55 through the outlet pipe 53 and the end cover is turned to open. The blown gas will assist the extension plate 33 to blow the impurities to the slot 19, thereby completing the efficient collection and cleaning of impurities on the sea surface in the aquaculture cage body 1. After the extrusion is completed, the second electric push rod 32 returns to its original position with the fixing plate 51 and the extending plate 33 , so that the elastic block 54 is no longer extruded.

[0052] The extension plate 33 is provided with a dredging mechanism 60, which includes a slide bar 61 slidably connected in the storage frame 18, one end of the slide bar 61 is in the storage slot 31, and the other end of the slide bar 61 is in the notch 19. The end of the slide bar 61 in the storage slot 31 is fixedly installed with a first magnetic block 63, and one end of the first magnetic block 63 is fixedly installed with a first spring 64, and one end of the first spring 64 is fixedly connected to the storage slot 31. A plurality of second magnetic blocks 65 are intermittently fixedly installed on one side of the extension plate 33, and a dredging plate 62 is fixedly installed on one end of the slide bar 61 in the notch 19. The bottom of the dredging plate 62 is provided with a plurality of cavities 66, and the interior of the cavity 66 is sealed and slidably connected with a push plate 67 through a second spring 68, and an impact ball 69 is engraved in the cavity 66, and one side of the push plate 67 is in contact with the impact ball 69.

[0053] During operation, the second electric push rod 32 will move with several intermittent second magnetic blocks 65 on the surface when moving with the extension plate 33. When the second magnetic block 65 approaches the first magnetic block 63, the first magnetic block 63 on the slide bar 61 will repel each other with the same sex, thereby sliding and compressing the first spring 64, and moving the dredging plate 62 in the direction away from the storage slot 31. When moving, the dredging plate 62 will continuously drive the impact ball 69 to impact the holes of the filter frame 20, thereby generating vibrations, and shaking the impurities on the filter screen 84, thereby achieving the purpose of loading more residual bait and feces. At the same time, the continuous impact on the holes of the filter frame 20 can also keep it unobstructed, thereby ensuring the subsequent outflow of seawater. Since the aquaculture cage body 1 is cylindrical, when the storage frame 18 moves, the extension plate 33 will continuously slide, contract and extend, thereby keeping the impact ball 69 efficiently impacting the filter frame 20, and achieving efficient loading and dredging.

[0054] A disinfection mechanism 80 is provided in the storage tank 31. The disinfection mechanism 80 includes a loading box 81 fixedly installed in the storage tank 31 and made of rubber material. A connecting pipe 82 with a one-way valve is fixedly installed at the bottom of the loading box 81. A plurality of liquid outlet holes 83 are opened on the surface of the connecting pipe 82. A liquid inlet pipe connected to the inside and with a one-way valve is fixedly installed on the top of the loading box 81. A filter 84 is fixedly installed in the liquid outlet hole 83.

[0055] During operation, when the second electric push rod 32 and the extension plate 33 are continuously sliding, contracting and extending, the second electric push rod 32 and the fixing plate 51 are also continuously squeezing the loading box 81, so that the disinfectant in the loading box 81 is quickly filled into the connecting pipe 82, and flows into the seawater of the breeding net cage body 1 through the liquid outlet 83 and the filter screen 84 of the connecting pipe 82. By spraying the disinfectant, pathogenic microorganisms such as bacteria, viruses, fungi, etc. in the environment inside and outside the breeding net cage body 1 are killed, reducing the risk of fish infection and allowing the large yellow croaker seedlings to grow better. When it is not necessary to spray the disinfectant, the loading box 81 can be kept idle.

[0056] Working principle: When there is a large amount of feces discharged by large yellow croaker, unused feed or other impurities on the sea surface in the aquaculture cage body 1, the servo motor 12 on the base 11 is started, and the servo motor 12 and the screw rod 13 are used to move the sleeve frame 15, and the fixed frame 16, the first electric push rod 17 and the storage frame 18 at the bottom of the sleeve frame 15 will move with it. The first electric push rod 17 in the fixed frame 16 drives the storage frame 18 to move up and down, so that the notch 19 of the storage frame 18 is partially under the sea surface, and the rest is on the sea surface. As the servo motor 12 moves the storage frame 18, the impurities on the sea surface will enter the notch 19 and accumulate on the filter frame 20, thereby completing the collection of impurities floating on the sea surface. When the storage frame 18 moves to the end of the aquaculture cage body 1, the storage frame 18 is lifted by the first electric push rod 17, so that the seawater in the slot 19 of the storage frame 18 flows back into the sea through the filter frame 20, and the impurities are blocked by the filter frame 20 and remain in the slot 19 of the storage frame 18. At the same time, using the first electric push rod 17 to lift the storage frame 18 also facilitates subsequent staff to take out the collected impurities, thereby facilitating the reuse of the storage frame 18. Since the aquaculture cage body 1 is exposed to the sea for a long time, the multi-stage telescopic tube 70 can be installed to protect the screw rod 13.

[0057] When the storage frame 18 moves in the aquaculture net box body 1, it will move with the second electric push rods 32 and the extension plate 33 on both sides. The second electric push rod 32 monitors through the sensor 34 so that the roller 35 at one end of the extension plate 33 always fits with the inner wall of the aquaculture net box body 1. Since the aquaculture net box body 1 is cylindrical, as the storage frame 18 moves, the second electric push rod 32 will move with the extension plate 33 in the direction away from the storage slot 31, so that one side of the extension plate 33 always fits with the inner wall of the aquaculture net box body 1. The roller 35 fits with the inner wall of the aquaculture net box body 1 to reduce friction and facilitate movement. The installed partition 40 and sealing ring can effectively prevent seawater from entering the storage slot 31, thereby ensuring the normal operation of the components of the storage slot 31. When the storage frame 18 brings the second electric push rod 32 and the extension plate 33 close to the end of the aquaculture cage body 1, the second electric push rod 32 brings the extension plate 33 to move to the storage frame 18 to reset. At this time, the arc-shaped extension plate 33 brings the impurities to the storage frame 18, and assists the impurities to enter the notch 19 for collection. When the extension plate 33 brings the impurities to reset to the notch 19 of the storage frame 18, the extension plate 33 moves to the initial position and stops. At this time, the second electric push rod 32 continues to drive the extension plate 33 and the fixed plate 51 to move excessively. The extension plate 33 continues to drive the impurities to approach the notch 19. At this time, the fixed plate 51 will squeeze the elastic block 54 on the bottom bracket 52. The gas squeezed in the elastic block 54 is quickly filled into the outlet hole 55 through the outlet pipe 53 and rotates to open the end cover. The blown gas will assist the extension plate 33 to blow the impurities to the notch 19, thereby completing the efficient collection and cleaning of the impurities on the sea surface in the aquaculture cage body 1.

[0058] When the second electric push rod 32 moves with the extension plate 33, it will move with several intermittent second magnetic blocks 65 on the surface. When the second magnetic block 65 approaches the first magnetic block 63, the first magnetic block 63 on the slide bar 61 will repel each other with the same polarity, thereby sliding and compressing the first spring 64, and moving the dredging plate 62 in the direction away from the storage slot 31. When the dredging plate 62 moves, it will continuously drive the impact ball 69 to hit the holes of the filter frame 20, thereby generating vibrations, and shaking the impurities on the filter screen 84, thereby achieving the purpose of loading more impurities. At the same time, the continuous impact on the holes of the filter frame 20 can also keep it unobstructed, thereby ensuring the subsequent outflow of seawater. When the second electric push rod 32 and the extension plate 33 are constantly sliding, contracting and extending, the second electric push rod 32 will also continuously squeeze the loading box 81 with the fixed plate 51, so that the disinfectant in the loading box 81 is quickly filled into the connecting pipe 82, and flows into the seawater of the aquaculture cage body 1 through the liquid outlet 83 and the filter screen 84 of the connecting pipe 82.
