Description

Technical Field

[0001] The present invention relates to a culture tank capable of driving fish in a specific direction for catching or transferring, and a culture workboat using such a culture tank, belonging to the technical field of aquaculture. Background Art

[0002] At present, the existing flowing water culture and recirculating water culture technologies have been widely promoted and used in the aquaculture industry. Based on the culture containers, feed feeding, and water treatment equipment in a specific space, the culture water environment can be improved accordingly, the water culture density can be increased, and ultimately higher growth rates and yields can be obtained.

[0003] When the existing culture tank body is applied to large ship-type deep-sea fishery culture, different management and feeding measures need to be implemented according to each stage of the growth cycle. With the continuous development of large deep-sea culture facility technologies, the culture methods are required to adapt to the characteristics of the deep-sea environment.

[0004] For example, when considering both the culture modes of enclosed cabins and open cages, the cages are beneficial for increasing yields but are difficult to move and have poor mobility. Integrating enclosed culture and open culture can achieve the wild culture of fish from small fry to adult fish at sea. That is, starting from small-sized fry for sea culture can reduce the pressure on the environment caused by land or near-shore cage culture, and at the same time reduce the cost of transporting larger-sized fish at sea. However, in the subsequent stages of sorting cultured fish and catching adult fish, it is necessary to transfer aquatic organisms such as fish in a specific direction between the hull and the cage. In addition, in the face of relatively bad weather and sea conditions, etc., it is also necessary to drive the fish group back into the cabin in a specific direction. Therefore, how to achieve driving fish in a specific direction for catching or transferring, while reducing the damage to larger-sized fish bodies by traditional fish suction pump devices, simplifying the pipeline design and operating load of the hull management system, and correspondingly reducing the energy consumption of hull transfer has always been a design difficulty for deep-sea culture workboats or culture platforms in this field.

[0005] In view of this, this patent application is specifically proposed. Summary of the Invention

[0006] The culture tank with a lifting fish driving device and the culture workboat using such a culture tank according to the present invention propose an underwater lifting fish driving device to solve the problems existing in the above-mentioned prior art. The design focus of such a device is not to affect the internal culture environment of the tank during the entire cycle of aquatic organism feeding and growth, and be able to drive fish in a specific direction according to needs when catching or transferring fish groups, so as to achieve the design purposes of improving the efficiency of catching and transferring operations and reducing the damage to fish bodies of various size specifications.

[0007] To achieve the above design purpose, the breeding tank with a lifting fish driving device includes a frame assembly formed by sequentially splicing several side plates and a bottom plate, with a closed cavity inside. The difference from the prior art lies in that a hollow middle column is vertically arranged in the inner cavity of the frame assembly, a bridge is horizontally connected to the tops of several side plates, and each end of the bridge is respectively connected to the frame assembly of a workboat or an adjacent breeding tank through the side plates; a lifting frame is sleeved along the outer diameter of the middle column, and the lifting frame can vertically move up and down along the middle column under the drive of a lifting drive device; the outer dimension of the lifting frame is the same as the horizontal cross-section of the inner cavity of the frame assembly; several rectangular fish driving openings are formed in the lifting frame, a first hole is arranged along the horizontal center of the lifting frame, and the middle column is vertically sleeved in the first hole; a net frame is vertically supported and connected in a circle by several short columns along the four peripheral edges of each fish driving opening on the lifting frame; the fishnet pulling plate, under the drive of a catching drive device, reciprocally slides vertically upward along the net frame to drive the fishnet to cover or open the fish driving openings on the lifting frame.

[0008] The lifting drive device includes a first steel cable assembly, which consists of a first winch and a first steel cable; one end of the first steel cable, the first cable coiling head, is wound around the output shaft of the first winch, and the other end of the first steel cable, the second cable coiling head, is fixedly connected to the bridge; the first steel cable is a flexible body, and two vertically distributed winding parts are formed between the horizontally extending parts of the first cable coiling head and the second cable coiling head; the winding part located at the vertical top layer includes a winding arc with an axial center line in the horizontal direction and a winding arc with an axial center line in the vertical direction.

[0009] The catching drive device includes a group of fifth pulleys symmetrically distributed at a set of relative edges of the fish driving openings and respectively driven and connected by a second winch and a third winch. After the second steel cable and the third steel cable wound around and connected to the driving ends of the second winch and the third winch are respectively wound and connected to the fifth pulleys on both sides of the fish driving opening, they are docked on the fishnet pulling plate.

[0010] Each group of fifth pulleys is rotatably arranged through a third pulley hole on a group of second pulley plates arranged on the lifting frame; a pulling plate joint is fixedly arranged on the fishnet pulling plate, and the docking ends of the second steel cable and the third steel cable are respectively fixed to the pulling plate joint.

[0011] The fishnet pulling plate is slidably penetrated and connected to the net frame through a group of symmetrically distributed fifth holes arranged at its two ends. One end of the fishnet is wound around the net frame on one side of the fish driving opening, and the other end of the fishnet is fixedly connected to the fishnet pulling plate.

[0012] At least one group of horizontally distributed pulling plate holes is arranged on the fishnet pulling plate, and the fishnet is fixedly connected to the fishnet pulling plate through the pulling plate holes.

[0013] The top end of the middle vertical column is connected through the bridge, and its bottom end is connected through the bottom plate of the frame assembly and communicated with the water inlet end of the overflow pipe. The water outlet end of the overflow pipe is located outside the frame assembly; on the side wall of the middle vertical column, several groups of guide plates are symmetrically arranged along its vertical center line.

[0014] A lifting cleaning assembly that can move up and down vertically and clean the side plate surface and a bottom cleaning assembly that can rotate around the vertical center axis and clean the bottom plate surface are respectively sleeved along the outer diameter of the middle vertical column.

[0015] Based on the above-mentioned breeding pond with a lifting fish driving device, the present application proposes a new type of breeding workboat, which includes a hull, an upper deck located at the top of the hull, and a cabin formed by fixedly connecting a ship's board at the bottom of the inner cavity of the hull; several breeding ponds are installed on the upper deck, and the frame assembly of each breeding pond is fixedly connected to the upper deck separately.

[0046] What W1 points to in the figure is the aquaculture water level Specific implementation mode

[0047] The aquaculture tank with a lifting fish driving device proposed in this application can be set in land-based aquaculture facilities or inside deep-sea aquaculture vessels and aquaculture platforms for cultivating various types of aquatic organisms. In the aquaculture tank, the full-cycle aquaculture, automatic sorting and catching operations from fry to catching can be realized, and the water depth and oxygen concentration and other indicators inside the tank body can be adjusted according to the aquaculture plan, so as to realize dynamic and refined aquaculture management.

[0048] Example 1, as Figures 1 to 25 shown, the aquaculture tank with a lifting fish driving device includes a frame assembly 100 formed by sequentially splicing several side plates 101 and a bottom plate, and the interior is a closed cavity. The frame assembly 100 can be integrally connected to the deck of the vessel, embedded in the cabin of the vessel, or installed on the shore for use; the frame 101 is a polyhedron structure as an octagonal prism shape in the figure;

[0049] A hollow intermediate column 102 is vertically arranged in the inner cavity of the frame assembly 100, and a bridge 103 for laying equipment and allowing operators to walk and stand is horizontally connected to the top of the inner cavity of the frame assembly 100; in this embodiment, the bridge 103 is a cross-shaped structure, and each end of the bridge 103 is connected to the frame assembly 100 of the vessel or an adjacent aquaculture tank through the side plate 101;

[0050] A feeding assembly 200 is installed on the bridge 103, which includes a hopper and a feeding pipe communicating with the hopper. A stirring assembly that rotates axially on a fixed shaft is arranged inside the feeding pipe, and several feeding ports distributed axially are arranged on the side wall of the feeding pipe; when the stirring assembly operates, the bait added from the hopper moves in the feeding pipe and is then thrown out from the feeding ports to the aquaculture water body below respectively.

[0051] A lifting frame 401 is sleeved on the outer diameter of the middle column 102, and the lifting frame 401 can move vertically up and down along the middle column 102 under the drive of a lifting drive device.

[0052] The external dimension of the lifting frame 401 is the same as the horizontal cross-section of the inner cavity of the frame assembly 100.

[0053] In this embodiment, the lifting frame 401 has an octagonal prism shape. The lifting frame 401 is used to carry the catching device and realize the function of directionally driving fish schools during the vertical lifting process. Several rectangular fish driving ports are opened on the lifting frame 401 for aquatic organisms such as fish schools to pass through without affecting their normal swimming and growth.

[0054] A first hole 402 and four first grooves 416 are arranged along the horizontal center of the lifting frame 401, and the middle column 102 is vertically sleeved in the first hole 402.

[0055] A net frame 408 is vertically supported and connected by several short columns 409 along the four perimeters of each fish driving port on the lifting frame 401.

[0056] A net pulling plate 440 is slidably penetrated and connected to the net frame 408 through a set of symmetrically distributed fifth holes 441 arranged at both ends thereof. One end of a fishing net (not shown in the figure) is wound around the net frame 408 on one side of the fish driving port, and the other end of the fishing net is fixedly connected to the net pulling plate 440.

[0057] Under the drive of a catching drive device, the net pulling plate 440 reciprocally slides vertically upward along the net frame 408 to drive the fishing net to cover or open the fish driving ports on the lifting frame 401; when the fish driving ports are covered by the fishing net, when the lifting frame 401 moves vertically up and down along the vertical center of the middle column 102, the fish schools and other aquatic organisms in the aquaculture tank can be directionally driven upward or downward to realize catching or transferring to other aquaculture tanks or other aquaculture workboats; when the fish driving ports are opened, since the fishing net does not cover the lifting frame 401, even if the lifting frame 401 moves vertically up and down along the vertical center of the middle column 102, it will not affect the normal activities and growth of the fish schools and other aquatic organisms in the aquaculture tank.

[0058] Furthermore, the lifting drive device adopted in this embodiment is the first cable assembly 300, which is composed of a first winch 301 and a first cable 302. One end of the first cable 302, i.e., the first cable winding head 303, is wound around the output shaft of the first winch 301, and the other end of the first cable 302, i.e., the second cable winding head 304, is fixedly connected to the bridge 103. The first winch 301 is also fixedly installed on the bridge 103.

[0059] The first cable 302 is a flexible body, and two layers of vertically distributed folding parts are formed between the horizontally extending parts of the first cable winding head 303 and the second cable winding head 304. Among them, there are four folding parts at the vertical bottom layer, namely the first folding arc 305, the second folding arc 306, the third folding arc 307, and the fourth folding arc 308. The folding part at the vertical top layer includes a fifth folding arc 309 with its axial center line in the horizontal direction (as shown in Figure 12 and Figure 13 , there are 7 fifth folding arcs 309), and a sixth folding arc 310 with its axial center line in the vertical direction (as shown in Figure 12 and Figure 13 , there are 6 sixth folding arcs 310).

[0060] The catching drive device described in this embodiment includes two groups of seventh pulleys 422 symmetrically distributed at a set of relative edges of the fish driving opening and respectively driven and connected by a second winch 420 and a third winch 430. After the second cable 421 and the third cable 431 wound around and connected to the driving ends of the second winch 420 and the third winch 430 are respectively wound and connected to the seventh pulleys 422 on both sides of the fish driving opening, they are docked on the fishing net pulling plate 440.

[0061] Specifically, each group of seventh pulleys 422 is rotatably arranged on a set of second pulley plates 415 provided on the lifting frame 401 through a third pulley hole 416.

[0062] A pulling plate joint 443 is fixedly arranged on the fishing net pulling plate 440, and the docking ends of the second cable 421 and the third cable 431 are respectively fixed on the pulling plate joint 443.

[0063] The second winch 420 and the third winch 430 can be respectively installed at the bottom of the bridge 103.

[0064] When the lifting frame 401 is stationary in the vertical direction, by the one-way winding and releasing of the second winch 420 and the third winch 430, the second cable 421 and the third cable 431 are simultaneously driven to move in the same direction, so that the fishing net is driven by the pulling plate joint 443 to move towards the fish driving opening side on the lifting frame 401, realizing the covering or opening of the fish driving opening by the fishing net.

[0065] When the lifting frame 401 descends vertically along the middle column 102, the second winch 420 and the third winch 430 simultaneously release the second steel cable 421 and the third steel cable 431; when the lifting frame 401 ascends vertically along the middle column 102, the second winch 420 and the third winch 430 simultaneously retrieve the second steel cable 421 and the third steel cable 431, so as to achieve the coordinated operation of the cleaning and catching devices without mutual interference.

[0066] Furthermore, at least one group of horizontally distributed pull plate holes 442 are provided on the fishing net pull plate 440, and one end of the fishing net is fixedly connected to the fishing net pull plate 440 through the pull plate holes 442.

[0067] The top end of the middle column 102 is connected through the bridge 103, and its bottom end is connected through the bottom plate of the frame assembly 100 and communicated with the water inlet end of the overflow pipe 107, and the water outlet end of the overflow pipe 107 is located outside the frame assembly 100;

[0068] A number of residual bait through holes 106 are provided on the side wall of the middle column 102 to introduce the residual bait in the inner cavity of the frame assembly 100 into the middle column 102, and then flow out of the inner cavity of the frame assembly 100 through the overflow pipe 107 with the water flow to keep the internal breeding environment relatively clean;

[0069] A number of flow guiding plates 105 are symmetrically arranged on the side wall of the middle column 102 along its vertical center line. When the circulating water flow is injected into the inner cavity of the frame assembly 100, the blocking and counter-pushing effects of the flow guiding plates 105 can assist in forming a directional water flow with a certain flow direction and flow rate, thereby improving the effect of simulating the real aquatic environment;

[0070] A horizontally annular distributed fish outlet 126 is formed at the side part of the connection between the middle column 102 and the bottom plate. Dead aquatic organisms can enter the overflow pipe 107 through the fish outlet 126 under the action of the water flow and are finally discharged;

[0071] A number of first water inlet pipes 104 are vertically distributed in the inner cavity of the frame assembly 100. The side part of each group of first water inlet pipes 104 is connected through the side plate 101 and the second water inlet pipe 110 is connected to the outer end. The top of the first water inlet pipe 104 is fixedly connected to the bottom of the bridge 103 to increase the connection stability of its overall structure;

[0072] For the first water inlet pipe 104, its bottom is closed and does not contact the bottom plate of the frame assembly 100, and a number of water inlets 111 are opened on its side wall. After the breeding water enters the first water inlet pipe 104, it is discharged into the inner cavity of the frame assembly 100 through the water inlets 111;

[0073] A plurality of fish inlet pipes 118 are connected through the side plates 101. One end of each fish inlet pipe 118 communicates with the fish inlet 130 on the side plate 101 to introduce aquatic organisms such as fish into the inner cavity of the frame assembly 100 through the fish inlet pipes 118.

[0074] An electromagnetic valve 108 is installed on the pipeline of the overflow pipe 107. The side part of the overflow pipe 107 is bypass-connected to the fish suction pipe 109, and the external port of the fish suction pipe 109 is adjacent to the position of the aquaculture water level W1 in the inner cavity of the frame assembly 100.

[0075] A lifting and cleaning assembly 400 that can move vertically up and down along the outer diameter of the middle column 102 and clean the surface of the side plate 101, and a bottom cleaning assembly 500 that can rotate around the vertical central fixed axis and clean the bottom plate surface are respectively sleeved along the outer diameter of the middle column 102.

[0076] For the lifting and cleaning assembly 400, a brush (not shown in the figure) is provided on the outer edge of the lifting frame 401 to clean the surface of the side plate 101 during the vertical up and down movement of the lifting frame 401.

[0077] A first hole 402 and four first grooves 416 are provided along the horizontal center of the lifting frame 401. When the lifting frame 401 moves up and down along the middle column 102 under the drive of the above-mentioned lifting drive device, four groups of flow guiding plates 105 on the side wall of the middle column 102 respectively penetrate through the corresponding first grooves 416.

[0078] Four groups of second holes 403 with the same number as the first water inlet pipes 104 are provided on the lifting frame 401, and the four groups of first water inlet pipes 104 are respectively vertically sleeved in the corresponding second holes 403.

[0079] Two groups of lifting rollers 407 are provided on the side of each second hole 403. Each group of lifting rollers 407 is axially connected to a group of lifting pulley plates 406 installed on the lifting frame 401 through horizontally arranged lifting pulley plate holes 414 at both ends. The lifting rollers 407 roll and fit on the outer side of the first water inlet pipe 104 and can rotate around a fixed axis; when the lifting frame 401 moves up and down along the middle column 102 under the drive of the lifting drive device, the lifting rollers 407 roll along the outer side of the first water inlet pipe 104 to provide auxiliary support and guidance.

[0080] On the lifting frame 401, a first pulley 405, a second pulley 410, a third pulley 411, and a fourth pulley 412 are respectively axially arranged on a group of first pulley plates 404 through first pulley holes 41; among them, the first pulley 405 is folded and connected to the first folding arc 305, the second pulley 410 is folded and connected to the second folding arc 306, the third pulley 411 is folded and connected to the third folding arc 307, and the fourth pulley 412 is folded and connected to the fourth folding arc 308.

[0081] Correspondingly, at the bottom of the bridge frame 103, there are 7 groups of axially opposite first round plates 119 and second round plates 121. On each group of first round plates 119, there are first holes 120 opened horizontally, and on each group of second round plates 121, there are second holes 124 opened horizontally, as well as third holes 122 and fourth holes 125 opened vertically. At the same time, a first groove 123 is horizontally arranged on the second round plate 121; the first hole 120 and the second hole 124 are horizontally coaxial, and the third hole 122 and the fourth hole 125 are vertically coaxial;

[0082] Both ends of the shaft of the fifth pulley 320 are respectively sleeved in the first hole 120 and the second hole 124 and can rotate around a fixed axis; both ends of the shaft of the sixth pulley 330 are sleeved in the third hole 122 and the fourth hole 125 and can rotate around a fixed axis. The body of the sixth pulley 330 is accommodated in the first groove 123 but they do not contact each other;

[0083] The fifth pulley 320 is fold - connected to the fifth folding arc 309, and the sixth pulley 330 is fold - connected to the sixth folding arc 310.

[0084] If the above - mentioned lifting drive device adopts the design scheme of the first cable assembly 300, driven by the first winch 301, the first cable 302 realizes the "retracting" and "releasing" operations between the bridge frame 103 and the lifting frame 401 vertically, that is, the vertical length of the first cable 302 is dynamically variable; relative to the fixedly installed bridge frame 103, the lifting frame 401 realizes the vertical position change. When the lifting frame 401 moves up and down vertically, the brush attached to its outer edge can reciprocally clean the surface of the side plate 101, thereby cleaning the inner wall of the aquaculture bin body, making it difficult for aquatic organisms such as barnacles to attach and grow.

[0085] The bottom cleaning assembly 500 described above includes a rotating ring 501 slidably sleeved outside the middle upright 102, and a bottom cleaning transmission assembly 600 for driving the rotating ring 501 to rotate around the vertical center of the middle upright 102;

[0086] For the rotating ring 501, one ends of 2 groups of first rotating arms 502 are symmetrically connected to its outer circumference. At the other ends of each group of first rotating arms 502, one ends of a group of second rotating arms 503 are connected. At the other ends of the second rotating arms 503, third rollers 512 that are in rolling contact with the side plate 101 of the frame assembly 100 are axially provided. At the same time, a group of tension springs 530 are also connected between the side parts on the same side of each group of first rotating arms 502 and second rotating arms 503; Brushes (not shown in the figure) are installed at the bottoms of the first rotating arms 502 and the second rotating arms 503;

[0087] Under the adjustment of the elastic force of the tension spring 530, the second rotating arm 503 has a tendency to be always pulled towards the rear end of the first rotating arm 502. Even if the horizontal cross-sectional shape of the inner cavity of the frame assembly 100 formed after the side plates 101 are spliced is regular or irregular, the third roller 512 at the outer end of the second rotating arm 503 can still effectively abut against the side plate 101 of the frame assembly 100 all the time;

[0088] Further, several first rollers 505 that are in rolling contact with the bottom plate of the frame assembly 100 are installed at the bottom of the swivel ring 501, and several second rollers 509 that are in rolling contact with the bottom plate of the frame assembly 100 are axially arranged on the side of the first rotating arm 502;

[0089] Specifically, several first slots 504 are provided at the bottom of the swivel ring 501, and several first rollers 505 are respectively fixedly connected to the first slots 504 through first slot holes 507 for axial rotation;

[0090] A second slot 506 is provided at the connection between the swivel ring 501 and the first rotating arm 502. A vertically distributed second slot hole 508 is provided in the second slot 506. The end of the first rotating arm 502 is fixedly connected to the swivel ring 501 through a vertical pin shaft and the second slot hole 508 for axial rotation;

[0091] A third slot 519 is provided at the connection end between the first rotating arm 502 and the second rotating arm 503. A pair of vertically arranged third slot holes 520 are provided in the third slot 519. The relative ends of the first rotating arm 502 and the second rotating arm 503 are rotatably connected to the third slot holes 520 through a vertical shaft and the third slot holes 520;

[0092] A set of first lugs 515 and a second lug 510 are provided on the side of the first rotating arm 502. Horizontally distributed first lug holes 516 are relatively provided on the first lugs 515. The second roller 509 is fixedly connected to the first lugs 515 through the first lug holes 516 for axial rotation;

[0093] The second lug 510 is provided with a second lug hole 517. A third lug 511 is provided on one side of the connection end between the second rotating arm 503 and the first rotating arm 502. The third lug 511 is provided with a third lug hole 518; One end of the tension spring 530 is connected to the second lug hole 517, and the other end is connected to the third lug hole 518;

[0094] A fourth slot 513 is provided at the end of the second rotating arm 503. A pair of vertically arranged fourth slot holes 514 are provided in the fourth slot 513. The third roller 512 is fixedly connected to the end of the second rotating arm 503 through the fourth slot holes 514 for axial rotation;

[0095] For the bottom cleaning assembly 500 with the above structural features, both the first swing arm 502 and the second swing arm 503 can rotate synchronously around the vertical center of the middle column 102. As a result, it conforms to the shape and angular undulations of the side plate 101 and the bottom plate of the frame assembly 100, so as to maintain gapless contact between the above two groups of swing arms and the inner wall and bottom of the aquaculture tank during the cleaning process. Under the rolling support of the first roller 505, the second roller 509, and the third roller 512, when the rotating ring 501 rotates around the vertical center of the middle column 102, the rotating ring 501 drives the first swing arm 502 and the second swing arm 503 to rotate synchronously clockwise or counterclockwise. At the same time, the brush can reciprocally and circularly clean the bottom surface of the frame assembly 100, making it difficult for aquatic organisms such as barnacles to attach and grow.

[0096] Furthermore, a circle of internal teeth 540 is provided on the inner circumference of the rotating ring 501. The bottom cleaning transmission assembly 600 includes a third reduction motor 601, a rotating shaft 602 connected to the driving end of the third reduction motor 601, and a transmission gear 603 sleeved on the rotating shaft 602. The transmission gear 603 is meshed and connected to the internal teeth 540. Driven by the third reduction motor 601, while the rotating shaft 602 rotates axially, it drives the internal teeth 540 to rotate through the transmission gear 603, thereby driving the rotating ring 501 to rotate simultaneously around the vertical center of the middle column 102.

[0097] Specifically, a motor plate 112 for installing the third reduction motor 601 and a guiding ring 116 are sleeved on the middle column 102. A motor hole 114 is vertically opened on the motor plate 112, and the top end of the rotating shaft 602 is penetrated and connected to the motor hole 114 to realize the connection with the driving end of the third reduction motor 601. A concave avoidance opening 117 is opened on the side wall of the middle column 102. The transmission shaft plate 113 formed on the side of the guiding ring 116 extends into the avoidance opening 117, and a transmission shaft hole 115 is vertically opened on the transmission shaft plate 113. The transmission gear 603 is placed in the avoidance opening 117, and the bottom end of the rotating shaft 602 sequentially penetrates and connects the transmission gear 603 and the transmission shaft hole 115.

[0098] Based on the aquaculture tank with a lifting fish driving device designed as above, this embodiment also proposes the following fish driving method for catching and / or transferring at the same time:

[0099] A hollow middle column 102 is vertically arranged in the inner cavity of the frame assembly 100 of the aquaculture tank, and a bridge 103 is horizontally connected to the top of the inner cavity of the frame assembly 100. Each end of the bridge 103 is respectively communicated with a workboat or an adjacent aquaculture tank;

[0100] The top end of the middle column 102 is penetrated and connected to the bridge 103, and its bottom end penetrates and connects the bottom plate of the frame assembly 100 and is communicated with the water inlet end of the overflow pipe 107;

[0101] Vertically distribute the first water inlet pipe 104 of the array in the inner cavity of the frame assembly 100. The bottom of each group of the first water inlet pipes 104 is closed and does not contact the bottom plate of the frame assembly 100. A plurality of water inlets 111 are opened on its side wall. After the aquaculture water enters the first water inlet pipe 104, it is discharged into the inner cavity of the frame assembly 100 through the water inlets 111.

[0102] Pass a plurality of fish inlet pipes 118 with openings at both ends through and connect them to the side plate 101, and its fish inlet is communicated with the inner cavity of the frame assembly 100.

[0103] During the aquaculture process, use a water pump to inject seawater into the first water inlet pipe 104 through the second water inlet pipe 110, and water enters the bin through the vertically distributed water inlets 111 on the side wall of the first water inlet pipe 104.

[0104] The seawater first fills the bottom of the inner cavity of the frame assembly 100, and then the water level gradually rises. When the water level reaches the aquaculture water level W1 and continues to add water, the overflow pipe 107 will discharge the excess water from the bottom.

[0105] Send the aquatic organisms to be cultured into the frame assembly 100 through the fish inlet 130 at the connection of the fish inlet pipe 118, and feed the cultivated bait through the feeding assembly 200.

[0106] Install a solenoid valve 108 on the pipeline of the overflow pipe 107. The side part of the overflow pipe 107 is bypass-connected to the fish suction pipe 109, and the external port of the fish suction pipe 109 is adjacent to the position of the aquaculture water level W1 in the inner cavity of the frame assembly 100; the dead aquatic organisms S1 in the inner cavity of the frame assembly 100 enter the overflow pipe 107 under the action of the water flow and are finally discharged.

[0107] When the aquaculture of aquatic organisms such as fish reaches the catching condition, or when it is necessary to transfer the aquatic organisms to other aquaculture bins or aquaculture workboats, control the lifting frame 401 to vertically descend along the middle column 102 to drive the aquatic organisms to the bottom of the inner cavity of the frame assembly 100, close the solenoid valve 108, and suck the aquatic organisms from the fish suction pipe 109 to the designated fishing device through the fish outlet 126 at the bottom of the middle column 102; or, control the lifting frame 401 to vertically rise along the middle column 102 to drive the aquatic organisms to the top of the inner cavity of the frame assembly 100, and the operators can carry out manual fishing on the bridge 103.

[0108] Specifically, under the drive of the catching drive device, the fishing net pulling plate 440 reciprocally slides vertically upward along the fishing net frame 408 to drive the fishing net to cover or open the fish driving opening on the lifting frame 401.

[0109] When it is necessary to drive the fish downward vertically, first, the second winch 420 and the third winch 430 simultaneously wind and unwind the second steel cable 421 and the third steel cable 431 to move the fishing net in the same direction and cover the fish driving opening; then, the lifting frame 401 descends vertically along the middle column 102 under the drive of the lifting drive device. The 4 groups of flow guiding plates 105 on the side wall of the middle column 102 respectively penetrate through the corresponding first grooves 416, and the lifting rollers 407 roll along the outer side of the first water inlet pipe 104 to provide auxiliary support and guidance; along with the vertical descent of the lifting frame 401 along the middle column 102, the second winch 420 and the third winch 430 simultaneously release the second steel cable 421 and the third steel cable 431, and the lifting frame 401 covered by the fishing net drives the aquatic organisms to the bottom of the inner cavity of the frame assembly 100; when the solenoid valve 108 is closed, the aquatic organisms are sucked from the fish outlet 126 at the bottom of the middle column 102 into the suction pipe 109 and then into the designated fishing device;

[0110] When it is necessary to drive the fish upward vertically, first, the second winch 420 and the third winch 430 simultaneously wind and unwind the second steel cable 421 and the third steel cable 431 to move the fishing net in the same direction and cover the fish driving opening; then, the lifting frame 401 ascends vertically along the middle column 102 under the drive of the lifting drive device. The 4 groups of flow guiding plates 105 on the side wall of the middle column 102 respectively penetrate through the corresponding first grooves 416, and the lifting rollers 407 roll along the outer side of the first water inlet pipe 104 to provide auxiliary support and guidance; along with the vertical ascent of the lifting frame 401 along the middle column 102, the second winch 420 and the third winch 430 simultaneously retrieve the second steel cable 421 and the third steel cable 431, and the lifting frame 401 covered by the fishing net drives the aquatic organisms to the top of the inner cavity of the frame assembly 100. The fish can be collected by using a suction fish pump or a dip net.

[0111] Along with the vertical lifting of the lifting frame 401 along the middle column 102, the second winch 420 and the third winch 430 simultaneously wind and unwind the second steel cable 421 and the third steel cable 431, which can effectively balance the coordinated operation of the cleaning and catching devices.

[0112] As Figure 1 shown, based on the overall structural design of the above-mentioned aquaculture tank, the aquaculture tank is placed on a deep-sea aquaculture ship to realize the aquaculture and catching operations of various types of aquatic organisms.

[0113] Several aquaculture tanks can be installed on the upper deck of the aquaculture ship, and the frame assembly 100 of each aquaculture tank is individually fixedly connected to the upper deck;

[0114] Similarly, several breeding bins can be installed on the ship board inside the work ship. Several frame components 100 are spliced and combined with each other to form an integrated breeding bin body structure. The side plates 101 of adjacent frame components 100 can be shared, and a plurality of frame components 100 are butted together to form a shared bin body side wall, thereby correspondingly saving the consumption of the side plates 101. Such an internal splicing structure design can significantly save the consumption of steel, and the effect is more obvious on large-scale breeding work ships such as 100,000-ton and 80,000-cubic-meter breeding water bodies.

[0115] In summary, the embodiments given in the accompanying drawings are only the preferred solutions to achieve the purpose of the present invention. For those skilled in the art, they can get inspiration therefrom and directly derive other alternative structures that conform to the design concept of the present invention. The other structural features obtained therefrom should also fall within the scope of the solutions described in the present invention.
