Description

Technical Field

[0001] The invention relates to a novel breeding method for realizing directional driving of fish for catching or transferring, and belongs to the field of aquaculture. Background Art

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

[0003] When the aquaculture tanks of the existing technology are applied to large-scale ship-type deep-sea fishery aquaculture, different management and feeding measures need to be implemented according to the various stages of the growth cycle. With the continuous development of large-scale deep-sea aquaculture facility technology, the aquaculture methods are required to be able to adapt to the characteristics of the deep-sea environment.

[0004] For example, the use of a closed cabin and an open cage farming model is beneficial to increasing production, but it is difficult to move and has poor maneuverability. The integration of closed farming and open farming can realize wild farming at sea from small fry to adult fish. That is, marine farming starts with small-sized fry to reduce the pressure on the environment caused by land or near-shore cage farming, and at the same time reduces the cost of transporting larger-sized fish at sea. However, in the subsequent stages of farmed fish sorting and adult fish catching, it is necessary to transfer fish and other aquatic organisms between the hull and the cage in a directional manner. In addition, in the event of relatively severe weather and sea conditions, it is also necessary to drive the fish back to the cabin in a directional manner. Therefore, how to achieve directional driving of fish for catching or transfer, while reducing the damage problem of traditional fish suction pump devices to larger fish bodies, simplifying the pipeline design and use load of the hull management system, and correspondingly reducing the energy consumption of hull transportation, has always been a design difficulty for deep-sea aquaculture vessels or aquaculture platforms in this field.

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

[0006] The method for catching and transferring fish in a breeding warehouse described in the present invention aims to solve the problems existing in the above-mentioned prior art and proposes an underwater lifting fish driving solution. This method can not affect the breeding environment inside the warehouse during the entire cycle of aquatic organism feeding and growth, and can drive the fish in a direction as needed when catching or transferring fish, thereby achieving the design purpose of improving the timeliness of catching and transferring operations and reducing damage to fish of various sizes and specifications.

[0007] In order to achieve the above-mentioned design objectives, the method for catching and transferring fish in the breeding warehouse is as follows: a hollow middle column is vertically arranged in the inner cavity of the frame assembly of the breeding warehouse, a bridge frame is horizontally connected to the top of the inner cavity of the frame assembly, and each end of the bridge frame is respectively connected to a work boat or an adjacent breeding warehouse; an array of first water inlet pipes is vertically distributed in the inner cavity of the frame assembly, the bottom of each group of first water inlet pipes is closed and does not contact the bottom plate of the frame assembly, and an array of water inlets is opened on its side wall, and the breeding water enters the first water inlet pipe and is discharged from the water inlet into the inner cavity of the frame assembly; a plurality of fish inlet pipes with openings at both ends are connected to the side plate through the side plate, and the fish inlets thereof are connected to the inner cavity of the frame assembly; the aquatic organisms to be cultured are connected to the frame assembly through the fish inlet pipes. The fish is fed into the fish inlet at the connection of the components, and the breeding bait is fed through the feeding component; the fishing net pulling plate is driven by the catching driving device to slide back and forth vertically upward along the fishing net frame to drive the fishing net to cover the fish driving port on the lifting frame or open the fish driving port; when the breeding and catching conditions are met or the aquatic organisms need to be transferred to other breeding warehouses or breeding work boats, the lifting frame is controlled to descend vertically along the middle column to drive the aquatic organisms to the bottom of the inner cavity of the frame component, and the aquatic organisms are sucked from the fish suction tube to the designated fishing device through the fish outlet at the bottom of the middle column; or, the lifting frame is controlled to rise vertically along the middle column to drive the aquatic organisms to the top of the inner cavity of the frame component, and fishing operations are carried out on the bridge.

[0008] Furthermore, when it is necessary to drive the fish vertically downward, firstly, the second and third winches are used to simultaneously retract and release the second and third steel cables to vertically descend the column between the second and third steel cables, the array guide plates on the side walls of the middle column respectively pass through the corresponding first grooves, and the lifting rollers roll along the outer side of the first water inlet pipe to provide auxiliary support and guidance; along with the vertical descent of the lifting frame along the middle column, the second and third winches simultaneously release the second and third steel cables, and the lifting frame covered by the fishing net drives the aquatic organisms to the bottom of the inner cavity of the frame assembly; after the solenoid valve is closed, the aquatic organisms are sucked from the fish suction tube into the designated fishing device from the fish outlet at the bottom of the middle column; when it is necessary to drive the fish vertically upward, firstly, the second and third winches are used to simultaneously retract and release the second and third steel cables to vertically descend the column between the second and third winches, and the lifting rollers roll along the outer side of the first water inlet pipe to provide auxiliary support and guidance; along with the vertical descent of the lifting frame along the middle column, the second and third winches release the second and third steel cables at the same time, and the lifting frame covered by the fishing net drives the aquatic organisms to the bottom of the inner cavity of the frame assembly; when it is necessary to drive the fish vertically upward, firstly, the second and third winches are used to simultaneously retract and release the second and third steel cables to vertically descend the column between the second and third winches, and the lifting frame covered by the fishing net drives the aquatic organisms to the bottom of the inner cavity of the frame assembly; The second and third steel cables are simultaneously retracted and released by the second and third winches to move the fishing net in the same direction and cover the fish-driving mouth; then, the lifting frame is driven by the lifting drive device to rise vertically along the middle column, and the array guide plates on the side walls of the middle column respectively pass through the corresponding first grooves, and the lifting rollers roll along the outer side of the first water inlet pipe to provide auxiliary support and guidance; as the lifting frame rises vertically along the middle column, the second and third winches simultaneously retract the second and third steel cables, and the lifting frame covered by the fishing net drives the aquatic organisms to the top of the inner cavity of the frame assembly; as the lifting frame rises vertically along the middle column, the second and third winches simultaneously retract and release the second and third steel cables.

[0009] Furthermore, the top end of the middle column is connected to the bridge frame, and the bottom end thereof is connected to the bottom plate of the frame assembly and is connected to the water inlet end of the overflow pipe. During the breeding process, a water pump is used to inject seawater into the first water inlet pipe through the second water inlet pipe, and water is introduced into the warehouse body through the water inlet vertically distributed on the side wall of the first water inlet pipe. Water first fills the bottom of the inner cavity of the frame assembly, and then the water level gradually rises. When the water level reaches the breeding level, water is continued to be added and the overflow pipe discharges excess water from the bottom.

[0010] Furthermore, a solenoid valve is installed on the pipeline of the overflow pipe, and the side of the overflow pipe is bypassed and connected to a fish suction pipe, and the external port of the fish suction pipe is adjacent to the breeding level of the inner cavity of the frame assembly; dead aquatic organisms in the inner cavity of the frame assembly enter the overflow pipe through the fish outlet under the action of the water flow and are finally discharged.

[0011] Furthermore, several breeding warehouses are installed on the upper deck of the breeding work ship or breeding platform, and the frame assembly of each breeding warehouse is individually fixedly connected to the upper deck; several breeding warehouses can also be installed on the shipboard inside the work ship, and several frame assemblies are spliced ​​and combined with each other to form an integrated breeding warehouse structure, and the side panels of adjacent frame assemblies are shared.

[0012] In summary, the method for transferring fish from a breeding warehouse proposed in this application has the following advantages:

[0013] 1. This application proposes improvements and optimizations for the submerged three-dimensional aquaculture of various types of aquatic organisms. Automated lifting and driving methods are used for the directional capture and transfer of fish and other aquatic organisms, which correspondingly assists in improving the efficiency of manual operations and the level of mechanized management and operation.

[0043] The aquaculture warehouse catching and transferring method proposed in this application is widely used in land-based aquaculture facilities or deep-sea aquaculture vessels and aquaculture platforms to cultivate various types of aquatic organisms. In the following aquaculture warehouse, full-cycle aquaculture, automated sorting and catching operations from seedlings to catching can be realized, and indicators such as water depth and oxygen concentration inside the warehouse can be adjusted according to the aquaculture plan, thereby realizing dynamic and refined aquaculture management.

[0044] Embodiment 1, as Figures 1 to 25 As shown, the breeding warehouse includes a frame assembly 100 formed by sequentially splicing a plurality of side panels 101 and a bottom panel, and having a closed cavity inside. The frame assembly 100 can be integrally connected to the deck of a work vessel, embedded in a work vessel cabin, or installed on a shore for use; the frame 101 is an overall polygonal structure, such as an octagonal prism shape in the figure;

[0045] A hollow middle column 102 is vertically arranged in the inner cavity of the frame assembly 100, and a bridge frame 103 for auxiliary equipment and workers to walk and stop is horizontally connected to the top of the inner cavity of the frame assembly 100; in this embodiment, the bridge frame 103 is a cross-shaped structure, and each end of the bridge frame 103 is connected to the frame assembly 100 of the work boat or the adjacent breeding warehouse through the side plate 101;

[0046] A feeding assembly 200 is installed on the bridge 103, which includes a hopper and a feeding pipe connected to the hopper. A stirring assembly that rotates along a fixed axis is arranged inside the feeding pipe, and a plurality of feeding ports distributed along the axial direction are arranged on the side wall of the feeding pipe. When the stirring assembly is running, the bait added from the hopper moves in the feeding pipe and is then thrown out from the feeding ports to the aquaculture water below.

[0047] A lifting frame 401 is sleeved along the outer diameter of the middle column 102. The lifting frame 401 can be vertically lifted and moved along the middle column 102 under the drive of the lifting drive device.

[0048] The outer dimensions of the lifting frame 401 are the same as the horizontal cross-section of the inner cavity of the frame assembly 100;

[0049] In this embodiment, the lifting frame 401 has an octagonal prism shape, and is used to carry the catching device and realize the function of directional driving of fish schools during the vertical lifting process. A plurality of rectangular fish driving openings are provided on the lifting frame 401, so that fish schools and other aquatic organisms can pass through them without affecting their normal swimming and growth.

[0050] A first hole 402 and four first slots 416 are provided along the horizontal center of the lifting frame 401, and the middle column 102 is vertically sleeved in the first hole 402;

[0051] A circle of fishing net frame 408 is vertically supported and connected to the four edges of each fish-driving opening on the lifting frame 401 through a plurality of short columns 409;

[0052] The fishing net pulling plate 440 is slidably connected to the fishing net frame 408 through a group of symmetrically distributed fifth holes 441 set at both ends thereof. One end of the fishing net (not shown in the figure) is wound around the fishing net frame 408 located at one side of the fish driving port, and the other end of the fishing net is fixedly connected to the fishing net pulling plate 440.

[0053] Driven by the catching drive device, the fishing net pulling plate 440 slides back and forth vertically upward along the fishing net frame 408, driving the fishing net to cover the fish driving opening on the lifting frame 401 or to open the fish driving opening; when the fish driving opening is covered by the fishing net, when the lifting frame 401 is lifted and lowered along the vertical center of the middle column 102, the fish and other aquatic organisms in the breeding warehouse can be driven upward or downward to achieve catching or transfer to other breeding warehouses or other breeding ships; when the fish driving opening is opened, since the fishing net does not cover the lifting frame 401, even if the lifting frame 401 is lifted and lowered along the vertical center of the middle column 102, it will not affect the normal activities and growth of the fish and other aquatic organisms in the breeding warehouse.

[0054] Furthermore, the lifting drive device used in this embodiment is a first steel cable assembly 300, which is composed of a first hoist 301 and a first steel cable 302; wherein one end of the first steel cable 302, namely a first coiled steel cable head 303, is wound on the output shaft of the first hoist 301, and the other end of the first steel cable 302, namely a second coiled steel cable head 304, is fixedly connected to the bridge 103, and the first hoist 301 is also fixedly installed on the bridge 103;

[0055] The first steel cable 302 is a flexible body, and two layers of folded parts distributed vertically are formed between the horizontal extension parts of the first coiled steel cable head 303 and the second coiled steel cable head 304; wherein the folded parts located at the vertical bottom layer are four, namely the first folded arc 305, the second folded arc 306, the third folded arc 307 and the fourth folded arc 308; the folded parts located at the vertical top layer include the fifth folded arc 309 (such as Fig.12 and Fig.13 As shown, there are 7 fifth winding arcs 309), a sixth winding arc 310 with the axial centerline in the vertical direction (such as Fig.12 and Fig.13 As shown, there are 6 sixth winding arcs 310);

[0056] The fishing driving device described in this embodiment includes two groups of seventh pulleys 422 symmetrically distributed at a group of opposite edges of the fish driving mouth, which are respectively driven and connected by the second winch 420 and the third winch 430, and the second steel cable 421 and the third steel cable 431 connected to the driving ends of the second winch 420 and the third winch 430 are respectively folded around the seventh pulleys 422 on both sides of the fish driving mouth, and then docked on the fishing net pulling plate 440;

[0057] Specifically, each set of seventh pulleys 422 is provided on a set of second pulley plates 415 provided on the lifting frame 401 through the third pulley holes 416;

[0058] A pull plate joint 443 is fixedly provided on the fishing net pull plate 440, and the butt ends of the second steel cable 421 and the third steel cable 431 are respectively fixed on the pull plate joint 443;

[0059] The second hoist 420 and the third hoist 430 may be installed at the bottom of the bridge 103 respectively.

[0060] When the lifting frame 401 is stationary in the vertical direction, the second winch 420 and the third winch 430 are retracted and released to simultaneously drive the second steel cable 421 and the third steel cable 431 to move in the same direction, so that the pull plate joint 443 drives the fishing net to move toward the fish-driving opening on the lifting frame 401, thereby covering the fishing net or opening the fish-driving opening.

[0061] When the lifting frame 401 descends vertically along the middle column 102, the second winch 420 and the third winch 430 release the second steel cable 421 and the third steel cable 431 at the same time; when the lifting frame 401 rises vertically along the middle column 102, the second winch 420 and the third winch 430 recover the second steel cable 421 and the third steel cable 431 at the same time, so that the cleaning and catching devices can work in coordination without affecting each other.

[0062] Furthermore, at least one group of laterally distributed pulling plate holes 442 is provided on the fishing net pulling plate 440 , and one end of the fishing net is fixedly connected to the fishing net pulling plate 440 through the pulling plate holes 442 .

[0063] The top end of the middle column 102 is connected to the bridge frame 103, and the bottom end is connected to the bottom plate of the frame assembly 100 and connected to the water inlet end of the overflow pipe 107. The water outlet end of the overflow pipe 107 is located outside the frame assembly 100.

[0064] An array of residual bait through holes 106 is provided on the side wall of the middle column 102 to guide 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 along with the water flow, so as to keep the internal breeding environment relatively clean;

[0065] On the side wall of the middle column 102, a plurality of guide plates 105 are symmetrically arranged along the vertical center line thereof. When circulating water is injected into the inner cavity of the frame assembly 100, the blocking and reverse thrust of the guide plates 105 can assist in forming a directional water flow with a certain flow direction and flow velocity, thereby improving the effect of simulating a real aquatic environment.

[0066] A horizontal annular fish outlet 126 is formed at the side 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 water flow and finally be discharged;

[0067] The array of first water inlet pipes 104 is vertically distributed in the inner cavity of the frame assembly 100. The side of each group of first water inlet pipes 104 is connected to the side plate 101 and connected to the second water inlet pipe 110 at the outer end. The top of the first water inlet pipe 104 is fixedly connected to the bottom of the bridge frame 103 to increase the connection stability of the overall structure.

[0068] The first water inlet pipe 104 has a closed bottom and does not contact the bottom plate of the frame assembly 100. An array of water inlets 111 is opened on its side wall. After the aquaculture water enters the first water inlet pipe 104, it is discharged from the water inlet 111 into the inner cavity of the frame assembly 100.

[0069] A plurality of fish inlet pipes 118 are connected to the side plate 101 , and one end of the fish inlet pipe 118 is connected to the fish inlet port 130 on the side plate 101 to guide fish and other aquatic organisms from the fish inlet pipe 118 into the inner cavity of the frame assembly 100 ;

[0072] The lifting cleaning assembly 400 is provided with a brush (not shown in the figure) on the outer edge of the lifting frame 401 to clean the surface of the side plate 101 during the vertical lifting process of the lifting frame 401;

[0073] A first hole 402 and four first slots 416 are provided along the horizontal center of the lifting frame 401. When the lifting frame 401 is driven by the lifting drive device to move up and down along the middle column 102, the four groups of guide plates 105 on the side wall of the middle column 102 respectively penetrate through the corresponding first slots 416;

[0074] The lifting frame 401 is provided with four groups of second holes 403, the same number as the first water inlet pipes 104, and the four groups of first water inlet pipes 104 are respectively vertically sleeved in the corresponding second holes 403;

[0075] Two sets of lifting rollers 407 are arranged on the side of each second hole 403. Each set of lifting rollers 407 is axially connected to a set of lifting pulley plates 406 installed on the lifting frame 401 through the lifting pulley plate holes 414 at both ends arranged horizontally. The lifting rollers 407 roll and fit the outer side of the first water inlet pipe 104 and can rotate around a fixed axis. When the lifting frame 401 is driven by the lifting drive device to move up and down along the middle column 102, the lifting rollers 407 roll along the outer side of the first water inlet pipe 104 to provide auxiliary support and guidance.

[0076] The lifting frame 401 is provided with a first pulley 405, a second pulley 410, a third pulley 411 and a fourth pulley 412 which are respectively axially arranged on a group of first pulley plates 404 through the first pulley hole 41; wherein the first pulley 405 is folded and connected to the first folded arc 305, the second pulley 410 is folded and connected to the second folded arc 306, the third pulley 411 is folded and connected to the third folded arc 307, and the fourth pulley 412 is folded and connected to the fourth folded arc 308;

[0077] Correspondingly, at the bottom of the bridge frame 103, 7 groups of first wheel plates 119 and second wheel plates 121 are arranged axially opposite to each other, each group of first wheel plates 119 is respectively provided with a first hole 120 opened in the horizontal direction, each group of second wheel plates 121 is respectively provided with a second hole 124 opened in the horizontal direction, and a third hole 122 and a fourth hole 125 opened in the vertical direction, and at the same time, a first groove 123 is opened in the second wheel plate 121; the first hole 120 is horizontally coaxial with the second hole 124, and the third hole 122 is vertically coaxial with the fourth hole 125;

[0079] The fifth pulley 320 is folded and connected to the fifth folding arc 309 , and the sixth pulley 330 is folded and connected to the sixth folding arc 310 .

[0080] If the lifting drive device adopts the design of the first steel cable assembly 300, under the drive of the first winch 301, the first steel cable 302 realizes "retraction" and "release" operation between the bridge frame 103 and the lifting frame 401 vertically, that is, the vertical length of the first steel cable 302 is dynamically variable; relative to the fixedly installed bridge frame 103, the lifting frame 401 realizes vertical position change, and when the lifting frame 401 is lifted and lowered vertically, the brush attached to its outer edge can reciprocately clean the surface of the side panel 101, thereby cleaning the inner wall of the breeding warehouse, making it difficult for aquatic organisms such as barnacles to attach and grow.

[0081] The bottom cleaning assembly 500 comprises a rotating ring 501 slidably mounted on the outside of the middle column 102, and a bottom cleaning transmission assembly 600 driving the rotating ring 501 to rotate around the vertical center of the middle column 102;

[0083] Under the adjustment of the elastic force of the tension spring 530, the second rotating arm 503 has a tendency to be always pulled toward 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 panels 101 are spliced ​​is regular or irregular, it can still effectively achieve that the third roller 512 at the outer end of the second rotating arm 503 always closely contacts the side panels 101 of the frame assembly 100;

[0091] In the bottom cleaning assembly 500 with the above structural features, the first rotating arm 502 and the second rotating arm 503 can both rotate synchronously around the vertical center of the middle column 102, resulting in the fluctuation of the shape and angle of the side plate 101 and the bottom plate of the frame assembly 100, thereby maintaining the gapless contact between the above two groups of rotating arms and the inner wall and the bottom of the breeding warehouse 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 rotating arm 502 and the second rotating arm 503 to rotate synchronously clockwise or counterclockwise, and at the same time, the brush can reciprocate and circulate to clean the bottom plate surface of the frame assembly 100, making it difficult for aquatic organisms such as barnacles to attach and grow.

[0092] Furthermore, a circle of internal teeth 540 is provided on the inner circumference of the rotating ring 501, and 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, and the transmission gear 603 is meshed and connected to the internal teeth 540; under the drive of the third reduction motor 601, the rotating shaft 602 rotates along a fixed axis and drives the internal teeth 540 to rotate through the transmission gear 603, so that the transmission rotating ring 501 can rotate simultaneously around the vertical center of the middle column 102.

[0093] Specifically, a motor plate 112 for mounting the third reduction motor 601 and a guide 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 connected to the motor hole 114 to achieve connection with the driving end of the third reduction motor 601; an inwardly concave avoidance opening 117 is opened on the side wall of the middle column 102, and a transmission shaft plate 113 formed on the side of the guide 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 is connected to the transmission gear 603 and the transmission shaft hole 115 in sequence.

[0094] Based on the above-mentioned structure design of the breeding warehouse with a lifting and driving fish device, this embodiment also proposes the following breeding warehouse catch transfer method:

[0095] A hollow middle column 102 is vertically arranged in the inner cavity of the frame assembly 100 of the breeding warehouse, and a bridge frame 103 is horizontally connected to the top of the inner cavity of the frame assembly 100, and each end of the bridge frame 103 is respectively connected to a work vessel or an adjacent breeding warehouse;

[0096] The top end of the middle column 102 penetrates and connects to the bridge frame 103, and the bottom end thereof penetrates and connects to the bottom plate of the frame assembly 100 and is connected to the water inlet end of the overflow pipe 107;

[0097] An array of first water inlet pipes 104 is vertically distributed in the inner cavity of the frame assembly 100. The bottom of each group of first water inlet pipes 104 is closed and does not contact the bottom plate of the frame assembly 100. An array of water inlet ports 111 is opened on the side wall. After the aquaculture water enters the first water inlet pipes 104, it is discharged from the water inlet ports 111 into the inner cavity of the frame assembly 100.

[0098] A plurality of fish inlet pipes 118 with openings at both ends are connected to the side plate 101, and the fish inlet openings thereof are connected to the inner cavity of the frame assembly 100;

[0099] During the breeding process, a water pump is used to inject seawater into the first water inlet pipe 104 through the second water inlet pipe 110, and water enters the warehouse through the water inlet 111 vertically distributed on the side wall of the first water inlet pipe 104;

[0100] 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 level W1, water is continued to be added, and the overflow pipe 107 discharges the excess water from the bottom;

[0101] The aquatic organisms to be cultured are fed into the fish inlet 130 at the connection between the fish inlet pipe 118 and the frame assembly 100, and the feed for breeding is fed through the feeding assembly 200;

[0102] A solenoid valve 108 is installed on the pipeline of the overflow pipe 107. The side of the overflow pipe 107 is bypassed and connected to a fish suction pipe 109. The external port of the fish suction pipe 109 is adjacent to the position of the culture 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 through the fish outlet 126 under the action of the water flow and are finally discharged.

[0103] When the aquatic organisms such as fish are cultivated to meet the conditions for catching, or when the aquatic organisms need to be transferred to other cultivation warehouses or cultivation vessels, the lifting frame 401 is controlled to descend vertically along the middle column 102 to drive the aquatic organisms to the bottom of the inner cavity of the frame assembly 100, the solenoid valve 108 is closed, and the aquatic organisms are sucked 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, the lifting frame 401 is controlled to rise vertically 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 perform manual fishing on the bridge 103;

[0104] Specifically, the fishing net pulling plate 440 is driven by the fishing driving device to slide reciprocatingly vertically upward along the fishing net frame 408 to drive the fishing net to cover the fish driving opening on the lifting frame 401 or to open the fish driving opening;

[0105] When it is necessary to drive the fish downward vertically, first, the second winch 420 and the third winch 430 are used to retract and release the second steel cable 421 and the third steel cable 431 at the same time to move the fishing net in the same direction and cover the fish-driving opening; then, the lifting frame 401 is driven by the lifting drive device to vertically descend along the middle column 102, and the four groups of guide plates 105 on the side wall of the middle column 102 respectively pass through the corresponding first grooves 416, and the lifting roller 407 moves along the outer side of the first water inlet pipe 104. Rolling to provide auxiliary support and guidance; as 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, 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 designated fishing device from the fish suction pipe 109;

[0106] When it is necessary to drive the fish upward vertically, first, the second winch 420 and the third winch 430 are used to simultaneously retract and release 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 is driven by the lifting drive device to vertically rise along the middle column 102, and the four groups of guide plates 105 on the side wall of the middle column 102 respectively penetrate through the corresponding first grooves 416, and the lifting roller 407 rolls along the outer side of the first water inlet pipe 104 to provide auxiliary support and guidance; along with the vertical rising process of the lifting frame 401 along the middle column 102, the second winch 420 and the third winch 430 simultaneously retract 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, and the fish can be collected by a fish suction pump or a scoop net;

[0107] As the lifting frame 401 is lifted and lowered vertically along the middle column 102, the second hoist 420 and the third hoist 430 simultaneously retract and release the second steel cable 421 and the third steel cable 431, which can effectively take into account the coordinated operation of the cleaning and catching devices.

[0108] like Figure 1 As shown, based on the overall structural design of the above-mentioned breeding warehouse, the breeding warehouse is placed on a deep-sea breeding ship to realize the breeding and catching operations of various types of aquatic organisms.

[0109] Several breeding warehouses can be installed on the upper deck of the breeding ship, and the frame assembly 100 of each breeding warehouse is individually fixedly connected to the upper deck;

[0110] Similarly, several breeding warehouses can be installed on the shipboard inside the work ship. Several frame assemblies 100 are spliced ​​together to form an integrated breeding warehouse structure. The side panels 101 of adjacent frame assemblies 100 can be shared. Multiple frame assemblies 100 are docked together to form a common warehouse side wall, thereby saving the side panels 101 accordingly. Such internal splicing structure design can significantly save the amount of steel, and the effect is more obvious on large-scale breeding work ships such as 100,000 tons and 80,000 cubic meters of breeding water.

[0111] In summary, the embodiments given in conjunction with the accompanying drawings are only preferred solutions for achieving the purpose of the present invention. For those skilled in the art, this can be enlightened and directly deduce other alternative structures that conform to the design concept of the present invention. Other structural features obtained thereby should also belong to the scope of the solution described in the present invention.
