Description

Technical Field

[0001] This utility model relates to a barrel-within-a-barrel ecological circular aquaculture system. Background Technology

[0002] Traditional pond aquaculture suffers from low wastewater treatment rates, leading to significant eutrophication. Modern facility-based aquaculture, with its highly controllable production environment, facilitates input reduction throughout the entire process, full resource utilization of waste, efficient centralized treatment of aquaculture wastewater, promotion of new energy sources and energy-saving and environmentally friendly facilities and equipment, increased supply of green and high-quality aquatic products, and accelerated green transformation of production methods. From the perspective of fisheries modernization, comprehensive and advanced facilities are a prominent feature of modern fisheries. In addition to emphasizing the "aquaculture facilities" themselves, facility-based aquaculture also incorporates automatic (precision) feeding systems, water quality monitoring systems, and wastewater treatment systems as needed. This significantly promotes the intensive, standardized, mechanized, green, and digital development of aquaculture, using infrastructure modernization to drive fisheries modernization. Ponds are the primary mode of aquaculture in my country. However, traditional intensive pond aquaculture, due to stocking densities exceeding the pond's self-purification capacity, easily leads to excessive accumulation of uneaten feed and feces, resulting in water quality deterioration, drug abuse, frequent disease outbreaks, and low overall efficiency. To overcome the bottlenecks in intensive pond aquaculture, facility-based fish farming models such as "racetrack fish farming," "container aquaculture," "land-based canvas bucket aquaculture," "factory-style aquaculture," and "pond enclosure aquaculture" have emerged.

[0003] A utility model patent with announcement number CN216164460U discloses a floating recirculating aquaculture device for fish farming, which can realize the enclosure of a tank-type pond in a pool. The upper part of the tank is provided with a ring of water inlet holes, through which external water is introduced to realize water circulation in the tank. This surface water inlet method makes it easy for algae and attached substances in the pond to clog the water inlet holes, resulting in poor water circulation in the tank, insufficient dissolved oxygen, and difficulty in guaranteeing the farming effect.

[0025] like Figure 1 As shown, the present invention provides a barrel-in-barrel ecological circular aquaculture system, including a floating aquaculture unit 10 set in a water area 1 and an aquaculture wastewater treatment unit 20 set on land 2. The aquaculture wastewater in the floating aquaculture unit 10 is transported to the aquaculture wastewater treatment unit 20 through a sludge suction unit 30. After the aquaculture wastewater is treated by the aquaculture wastewater treatment unit 20, it can be returned to the water area 1.

[0026] like Figure 2-9 As shown, in this embodiment, the floating aquaculture unit 10 includes a floating platform 300 and an aquaculture tank 100 supported on the floating platform 300. After the aquaculture tank 100 is supported on the floating platform 300, part of it is located in the water and part of it is located outside the water surface. In one embodiment, the floating platform 300 is positioned by a positioning member 50 to prevent it from drifting randomly in the water. At least part of the positioning member 50 can be set on the land 2, so that aquaculture-related operations can be performed on the floating platform 300 through the positioning member 50. The positioning member 50 can be a pull rope or a connecting bridge. In one embodiment, the positioning member 50 is set as a connecting bridge, with one end connected to the land 2 and the other end connected to the floating platform 300, so that it can serve as a channel connecting the land 2 and the floating platform 300. In another embodiment, one end of the positioning member 50 is hinged to the floating platform 300 through a hinge member 51, and the other end is connected to the land, so that a stable connecting bridge channel can be formed.

[0027] like Figure 3As shown, the floating platform 300 includes a support 301 and a floating component 302. The floating component 302 is, for example, a foam box, which is connected to the support 301. Therefore, the entire support 301 can be positioned above the water surface through the floating component 302. The support 301 can be a metal frame, such as a steel frame, on which a walkway is laid to facilitate workers' movement. The walkway is, for example, a grating. The support 301 is provided with walkway areas 300a. Multiple walkway areas 300a surround multiple empty areas 300b, for example, 2 or 4, forming a clustered aquaculture. The aquaculture tank 100 is placed in the empty area 300, with part of it in the water and part above the water surface. Since the empty area 300 is surrounded by the walkway areas 300a, workers can perform aquaculture-related operations on the space of the aquaculture tank 100 through the walkway areas 300a. The empty area 300 can be rectangular or circular to support the aquaculture tank 100. In this embodiment, the empty area 300 is rectangular to facilitate shaping and reduce costs. Figure 4 As shown, in one embodiment, a plurality of guard frames 301a are provided on the support 301 along the circumference of the aquaculture tank 100. At least a portion of the guard frames 301a extends along the height of the aquaculture tank 100. In one embodiment, the entire height of the tank is protected by the guard frames 301. The guard frames 301a wrap around the outside of the aquaculture tank in the circumferential direction to prevent it from breaking in the height direction, etc., so that the entire aquaculture tank 100 can be stably placed in the water. Figure 5 As shown, a movable frame 301b is provided on the bracket 301, and a storage rack 301c is provided at the bottom of the movable frame 301b. The movable frame 301b and the storage rack 301c form a storage space 301d. The storage rack 301c can be used to store operating equipment or items, such as the multi-port pipe connector 33 in the suction unit 30 or other equipment, such as suction pipes / water pumps / valves, etc. The storage rack 301c can also be set on the water surface, preferably close to the water surface. The movable frame 301b is set on the bracket 301 by a snap-fit ​​method or a rotation method. This kind of sandwich setting close to the water surface allows some parts to be placed on the water, which not only extends their service life, but also avoids direct exposure and misoperation caused by the sandwich placement, thus increasing safety.

[0028] The breeding tank 100 includes a tank body 101 and a tank bottom 102. The tank body 101 can be circular, and at least a portion of the tank bottom 102 is conical. Existing conventional breeding tanks can be selected, such as... Figure 6As shown, a fish-driving board 200 can be installed inside the aquaculture tank 100. The fish-driving board 200 is a circular plate with a fish-blocking net (not shown in the figure) installed on it. The fish-driving board 200 is designed to move relative to the aquaculture tank 100 along the height direction of the tank 100. Normally, it is located at the bottom of the tank 100. When fishing is needed, it moves towards the water surface to drive the fish to the surface for concentrated fishing. In one embodiment, the fish-driving board 200 is a circular plate with an annular ring 201 on its outermost ring. Multiple reinforcing ribs 202 are arranged between the annular rings 201. The fish-blocking net is laid on the annular rings 201 and / or the reinforcing ribs 202. The fish-driving board 200 is installed inside the aquaculture tank 100 and can move relative to the tank 100. Supported by a support member located inside the breeding tank 100, the outermost ring of the support member has a small gap with the inner wall of the breeding tank 100. Therefore, the fish-driving board 200 will not interfere with the inner wall of the breeding tank when it moves. In one embodiment, multiple connecting rods 203 are spaced apart along the circumference of the breeding tank 100 on the annular ring 201. The multiple connecting rods 203 extend along the height direction of the breeding tank, and one end of each rod has a lifting ring 203a. The rod can be lifted by a crane through the lifting ring 203a, thereby realizing automated movement. In another embodiment, the other end of the connecting rod 203 has a connecting part 203, which is connected to the annular ring 201. The connection method can be, for example, a threaded connection or a welded connection. Figure 7-8As shown, in order to lift the fish-driving board 200, a lifting device 400 is also provided on the floating platform 300. The lifting device 400 includes a frame 401 and a crane 402 mounted on the frame 401. The crane 402 can lift the fish-driving board 200. The crane 402 can be configured as a hoist or similar device. In one embodiment, a pulley 401a is provided on the frame 401. Therefore, one lifting device 400 can move on the floating platform 300 to lift fish in multiple aquaculture tanks. The fish board 200 is lifted. To achieve stable lifting of the fish board 200, in one embodiment, a crane 402 is connected to the fish board 200 via a lifting platform 403. The lifting platform 403 includes multiple lifting arms 403a spaced apart along the circumference of the aquaculture tank. One end of each lifting arm 403a is connected to a fixed plate 403b, and the other end is provided with a lifting connector. The fixed plate 403 is provided with a connecting ring 403b1 that connects to the crane / lifting rope. A first reinforcing beam 403c is connected between the walls 403a. In one embodiment, the first reinforcing beam 403c is arranged in such a way that multiple first reinforcing beams 403c form a closed ring along the circumference of the breeding tank. This arrangement simplifies the structure, makes it aesthetically pleasing, and provides good reinforcement. In another embodiment, a second reinforcing beam 403d is also provided above each lifting arm 403a. The second reinforcing beam 403d and the lifting wall 403a form a triangular structure. This arrangement provides better load-bearing capacity for the lifting arm 403a. In another embodiment, two lifting connectors (403a1 / 403a2) are spaced apart along the diameter of the breeding tank on the lifting arm 403a. The inner lifting connector 403a1 is used to connect with the lifting ring 203a of the connecting rod 203 on the fish-driving board 200. The outer lifting connector 403a2 can be connected with the lifting ring (not shown in the figure) on the breeding tank 100, thereby lifting the entire breeding tank 100, which facilitates the installation and maintenance of the breeding tank 100. like Figure 9 As shown, the fish-driving board 200 and the lifting device 400 in the above embodiment are used. Each connecting rod 203 on the fish-driving board 200 is connected to each lifting arm 403a on the lifting plate 403, thereby achieving a stable lifting effect.

[0029] like Figure 10-11As shown, the sludge suction unit 30 of this utility model includes multiple sludge suction branch pipes 31, a multi-port pipe connector 33, and a conveying pipe 35. One end of each sludge suction branch pipe 31 is connected to the opening 102a at the bottom of the breeding tank 100, and the other end is connected to the branch connector 33a of the multi-port pipe connector 33. Each sludge suction branch pipe 31 is equipped with an on / off valve 32, so that each sludge suction branch pipe 31 can be opened and closed individually. One end of the conveying pipe 35 is connected to the main connector 33b of the multi-port pipe connector 33, and the other end is connected to the aquaculture wastewater treatment unit 20. A water pump 34 is connected to the conveying pipe 35. In this new type of pipe, there are several ways to connect one end of the conveying pipe 35 to the main connector 33b of the multi-port pipe fitting 33. It can be a direct connection or an indirect connection (connected to the main connector 33b via a water pump). For example, in one embodiment, one end of the conveying pipe 35 is directly connected to the main connector 33b of the multi-port pipe fitting 33, and a water pump 34 is installed on the conveying pipe 35 (the conveying pipe 35 is divided into multiple sections by the water pump). In another embodiment, the water pump 34 is connected to the main connector 33b of the multi-port pipe fitting 33, one end of the conveying pipe 35 is connected to the water pump 34, and the other end leads to the aquaculture wastewater. In the processing unit 20 of this invention, there are multiple ways to provide an on / off valve 32 for each suction branch pipe 31. For example, in one embodiment, an on / off valve 32 is provided on the pipe of each suction branch pipe 31. In another embodiment, an on / off valve 32 is provided on the branch joint 33a of the multi-port pipe connector 33 that connects to each suction branch pipe 31. The configuration method can be that a separate on / off valve is connected to the corresponding branch joint 33a, or the corresponding on / off valve 32 is provided on the corresponding branch joint 33a. The on / off valves 32 are concentrated on the multi-port pipe connector 33 for convenient unified operation. In one embodiment, the on / off valve 32 is disposed on the multi-port pipe connector 33, and the multi-port pipe connector 33 and / or the water pump 34 are disposed on the aforementioned shelf 301c and hidden within the storage space 301d, facilitating operation for vacuuming and maintenance. In other embodiments, the water pump 34 can also be disposed on land for maintenance operations on land. In this invention, the on / off valve 32 is configured as a butterfly valve. In another embodiment, the on / off valve 32 can also be configured as a solenoid valve to achieve automatic control. In this invention, the water pump is configured as a variable frequency pump, thereby saving electricity.

[0030] like Figure 12-14As shown, this utility model is equipped with a water guide 60 to guide water from outside the breeding tank into the breeding tank, forming a water circulation within the breeding tank. The circulation process is as follows: the breeding wastewater in the breeding tank 100 is pumped from the bottom opening through the suction unit 30 to the breeding wastewater treatment unit 20, reducing the water volume in the breeding tank. Fresh water from the water area outside the breeding tank enters the breeding tank through the water guide 60 to replenish it, forming a water circulation from bottom to top within the breeding tank. The water guide 60 includes an inlet 60a and an outlet 60b that are interconnected. The inlet 60a is located in the water area outside the breeding tank to introduce water from the external water area into the water guide 60 through the inlet 60a1. The outlet 60b1 of the outlet 60b is used to guide water into the breeding tank, preferably located in the water area outside the breeding tank. There are various ways in which the water guide 60 is installed inside the breeding tank, including a configuration where at least a portion of the water outlet 60b1 is located inside the breeding tank, and a configuration where the water flow from the water outlet 60b1 is located inside the breeding tank. In one embodiment, the water guide 60 can be integrally formed as a single component, such as a water pipe, a flexible hose, or a corrugated pipe. In another embodiment, the water guide 60 includes multiple components, such as an inlet 60a as an inlet pipe and an outlet 60b as an outlet pipe, with the inlet pipe 60a and outlet pipe 60b connected to both sides of a pipe connector 61. In one embodiment, the inlet 60a1 of the end of the inlet pipe 60a connected to the pipe connector 61 is located on the outer side of the tank wall of the breeding tank 100. Located below the water surface, the outlet pipe 60b is equipped with a lifting component 70. The lifting component 70 can be configured as a pull rope or other structure capable of raising and lowering the outlet pipe 60b. The lifting component 70 can be connected to the inlet 60a1. The depth of the inlet 60a1 relative to the water surface 1 can be adjusted via the lifting component 70, allowing for the selective introduction of surface water, middle water, and bottom water. The lifting component 70 can be manually adjusted by pulling it. By adjusting the water depth at the inlet 60a1, water from different water layers can be selectively introduced into the aquaculture tank, effectively regulating the temperature of the aquaculture water. In other embodiments, the lifting component 70 can also be mechanically operated, linked to environmental parameters such as air and water temperature, enabling the aquaculture tank to... In one embodiment, for automatic adjustment of the internal water temperature, multiple water guides 60 are spaced apart along the circumference of the aquaculture tank. An installation opening 62 is provided on the tank body 101 of the aquaculture tank 100, penetrating the side wall of the tank body. The installation opening can be, for example, a mounting hole or a mounting groove. In one embodiment, it is a mounting hole, to which a pipe connector 61 is installed. A water outlet pipe 60b is connected to one end of the pipe connector 61, and its outlet 60b1 is located inside the tank wall of the aquaculture tank 100. In one embodiment, the multiple water outlet pipes 60b are inclined relative to the water surface inside the aquaculture tank. This arrangement increases the impact force of the water flow from the multiple water outlet pipes 60b, increasing the oxygen content while water is entering. In one embodiment, the aquaculture tank has a central axis L1 along its height direction.The center point of the mounting hole has a perpendicular line (O-O1 end) R1 connecting it to the central axis L1. When the breeding tank is circular, the perpendicular line R1 is the radius of the breeding tank. Projected along the height direction of the breeding tank, at least a portion of the water outlet pipe 60b is inclined relative to the radius R1 of the breeding tank. With this arrangement, the water flow from the water outlet pipe 60b impacts the liquid surface inside the breeding tank at an angle. The inclined impact of the water flow from multiple water outlet pipes 60b can cause the water inside the breeding tank to form a vortex, increasing the dissolved oxygen content of the water in the breeding tank. In one embodiment, multiple water outlet pipes 60b are arranged in parallel. With this arrangement, the water flow from each water outlet pipe 60b has the same inclination angle, which is more conducive to the formation of vortices. In another embodiment, the multiple mounting holes are positioned at the same height relative to the tank body. With this arrangement, the water flow from each water outlet pipe 60b has the same impact force, which can help form vortices. In one embodiment, for example... Figure 13 , 14 As shown, the water outlet pipe 60b extends along its length, forming an extension axis L2. Projected along the height of the aquaculture tank, the extension axis L2 is inclined relative to the vertical line R1. In one embodiment, the extension axis L2 intersects the vertical line R1, forming an angle Q1. Q1 is set as an acute angle, greater than 0 degrees and less than or equal to 90 degrees. Q1 mainly adjusts the tilt angle of the water outlet pipe 60b, which is related to the size of the vortex formed. The preferred angle for Q2 is 30-45 degrees, which facilitates the formation of a large-scale vortex in the impact water flow. In one embodiment, the inlet pipe 60a can be a flexible hose for easy adjustment of water intake. The length of the inlet pipe 60a is preferably greater than 1 meter to ensure that it reaches a deeper water layer for water intake. In one embodiment, the length of the inlet pipe 60a is greater than or equal to one-third of the length of the aquaculture tank, and its length is adapted to the size of the aquaculture tank to facilitate the selection of water from a suitable water layer. The outlet pipe 60b can be a rigid pipe to maintain a relative angle. In one embodiment, the outlet pipe 60b can also be equipped with an additional angle retainer to maintain a certain angle to stabilize the formation of the vortex water flow. Figure 15As shown, the water intake process of the water guide 60 of this utility model is as follows: the inlet 60a1 of the inlet pipe 60a is located below the water surface, for example, at the initial water intake level A (level A is below the water surface) in the water area outside a breeding tank. When the aquaculture tailwater in the breeding tank is sucked by the suction unit 30, the water level in the breeding tank drops, and its level B is lower than the initial water intake level A. Under the action of water pressure, water from outside the breeding tank enters the inlet pipe 60a and then flows out from the outlet pipe 60b into the breeding tank. Since the inlet pipe 60a is below the external water surface, its inlet 60a1 does not... It can be blocked by algae and attached substances in the pond, which can keep the water intake stable and continuous, ensuring smooth water circulation. During the water circulation process, the depth of the water inlet pipe 60a in the external water can be adjusted by the lifting component 70 to select water from different water layers. In one embodiment, after the water inlet and outlet pipes 60b achieve stable water output, the water inlet depth of the water inlet pipe 60a can be adjusted by the lifting component 70. Under the siphon effect of the water flow in the outlet pipe 60b, it can select water at a water level X lower than the liquid surface B, thereby enabling it to select water from any different water layer to better regulate the temperature of the water in the breeding tank.

[0031] The aquaculture tank of this utility model is also equipped with an aeration component 80. During non-suction periods of the aquaculture tank (such as during medication or feeding periods), air / oxygen can be blown in through the aeration pipe to increase the dissolved oxygen content of the water in the aquaculture tank. The aeration component can also adjust the aeration rate through a flow meter.

[0032] like Figure 16As shown, the aquaculture wastewater treatment unit 20 of this utility model is installed on land 2 to treat the aquaculture wastewater pumped from the aquaculture tank. It can be configured in various ways, such as a water tank, water tower, water bucket, or pool, depending on the adaptability to different aquaculture environments. In one embodiment, the aquaculture wastewater treatment unit 20 is a cement pool built on land 2. The aquaculture wastewater treatment unit 20 is equipped with an aquaculture wastewater treatment chamber 21. An inlet trough 22 is provided on the side of the aquaculture wastewater treatment chamber 21. The inlet trough has a water flow hole 22a communicating with the aquaculture wastewater treatment chamber 21. The water flow hole 22a is preferably located at the bottom of the inlet trough. Water pumped by the pump is received by the inlet trough 22 and then flows into the aquaculture wastewater treatment chamber 21, which can reduce water flow impact and achieve a slowing effect. In one embodiment, inlet troughs 22 are provided on both sides of the aquaculture wastewater treatment chamber 21, thereby enabling the introduction of multiple groups of aquaculture wastewater and achieving clustered aquaculture filtration. The aquaculture wastewater treatment chamber 21 is equipped with... The system includes a mounting bracket 21a with a filter plate 24. A conical sedimentation zone is located at the bottom of the aquaculture wastewater treatment chamber 21 to facilitate waste sedimentation. After entering the chamber, the aquaculture wastewater undergoes filtration and sedimentation, with feed, fish manure, and other waste deposited in the conical sedimentation zone. The bottom of the conical sedimentation zone is connected to a drain pipe 24, allowing the waste to be discharged via a drain pump. An overflow weir 25 with a drain outlet 25a is also provided within the aquaculture wastewater treatment chamber 21 to discharge the treated water.

[0035] like Figure 17-23As shown, in one embodiment, the present invention can also employ a breeding bucket made of spliced ​​plates. In one embodiment, the body 101 of the breeding bucket 100 of the present invention is formed by multiple plates 110. Along the height direction of the bucket body, the upper end of the bucket body 101 is provided with a first locking member 120 that holds the multiple plates 110, and the lower end is provided with a second locking member 130 that holds the multiple plates 110. The bottom 102 can be connected to the bucket body 101. The bottom 102 is configured to be deformable and unfold into a cone shape. The bottom 102 is provided with an opening 102a. The breeding bucket 100 is provided with a first support member 100a that can support the breeding bucket 100. The breeding bucket 100 is configured to accommodate a fish-driving board 200 that can move relative to the bucket body along the height direction of the bucket body. The breeding bucket 100 is provided with a second support member 100b that can support the fish-driving board 200.

[0036] The body 101 of the aquaculture tank 100 of this utility model is formed by multiple plates 110. The height and diameter of the tank can be customized by adjusting the size of the plates 110, so that the aquaculture tank can be adapted to different water depths according to local conditions. This truly breaks through the bottleneck restricting the promotion of the tank aquaculture method in ponds, and enables the tank aquaculture method in ponds to be widely promoted. The limiting component 100b set in the aquaculture tank 100 can be used to support the fish driving board 200 set in the aquaculture tank 100. When it is necessary to catch fish, the fish driving board 200 is lifted to drive the fish to the top of the tank, which can realize centralized catching, improve catching efficiency, and greatly reduce the injury and mortality of fish.

[0037] In this embodiment, the sheet material 110 can be selected from materials such as metal and plastic. In one embodiment, the sheet material 110 is set as fiberglass sheet (FRP), which is lightweight, strong, corrosion resistant, easy to transport, and can be used for a long time when submerged in water, thus reducing the overall cost of the product.

[0038] In this embodiment, each plate 110 is provided with an insertion part 110a and a mounting groove 110b at both ends. Multiple plates 110 are connected end to end to form a barrel body 101 (the insertion part 110a of one plate 110 is inserted into the mounting groove 110b of the adjacent plate, and the insertion part 110a of the adjacent plate is then inserted into the mounting groove 110b of the next plate 110, and so on, to form an end-to-end connection). In this way, multiple plates 110 are connected end to end to form an annular barrel body 101 (e.g., circular or elliptical), which is quick and convenient to assemble and easy to maintain. During maintenance, it is not necessary to replace the entire barrel body; only the plates that need to be replaced need to be replaced.

[0039] In this embodiment, the first locking member 120 and the second locking member 20 can be disposed on the outer wall or the inner wall of the barrel body. Their structural form can be a ring clamp, etc., and the clamp material can be metal, plastic, etc. In one embodiment, the first locking member 120 is a ring clamp, disposed on the upper end of the barrel body 101 to cover the plate 110. That is, the first locking member 120 covers at least a portion of the outer wall and / or inner wall of multiple plates 110 and the upper end of the plates 110. In one embodiment, the first locking member 120 is provided with a covering groove 121, and the upper end of the plate 110 can be disposed within the covering groove 121 to achieve the covering of the upper end, outer wall, and inner wall of the plate 110. With this arrangement, the first locking member 120 not only locks multiple plates in the circumferential direction... The material 110 covers the upper end of the plate 110, and the locking effect of multiple plates 110 is good and easy to install. In one embodiment, the second locking member 130 can adopt the same structure as the first locking member 120. In this case, along the height direction of the barrel, the multiple plates 110 are equivalent to being sandwiched between the first locking member 120 and the second locking member 130. The multiple plates 110 are connected end to end by snap-fit, and the overall structure is stable and reliable. In other embodiments, the second locking member 130 can also adopt other structures. For example, the second locking member 130 can be set as a sheet-like locking plate, which is connected to the multiple plates 110 and locked by fasteners to achieve locking between the multiple plates 110. In one embodiment, the second locking member 130 is set as a ring-shaped plate, such as a PP plate, which is connected to the multiple plates by fasteners to achieve locking.

[0040] In this embodiment, the upper and / or lower ends of the connection 110 (where the insertion part 110a mates with the mounting groove 110b) of each pair of adjacent plates 110 along the height direction of the barrel body are also connected to the first locking member 120 and / or the second locking member 130 by fasteners (140a). This arrangement is equivalent to any plate 110 being connected to the adjacent plate 110, the first locking member 120, and / or the second locking member 130 by the same fastener. With this structure, the entire barrel body 101 structure is tightly connected, not easily damaged, and has a longer service life. In other embodiments, fasteners (140b) are also provided at the middle part of the connection 110 between two adjacent plates 110 along the height direction of the barrel (excluding the connection between the upper and lower ends and the first locking member 120 and the second locking member 130). Multiple fasteners can be provided at intervals according to the length of the plate 110. The fasteners can be bolts, rivets, or other fasteners. With this arrangement, the middle part of the two adjacent plates 110 along the height direction of the barrel is also fastened by fasteners, and multiple plates will not detach from the connection at the middle part, so the overall structure can be stable.

[0041] In this embodiment, the bottom 102 of the bucket is made of materials such as plastic and silicone, so it can be deformed and unfolded. For example, in one embodiment, the bottom 102 of the bucket is set as a canvas bucket bottom. With this setting, the bottom 102 and the body 101 are made of different materials, which makes it easier to construct a conical bottom space.

[0042] In this embodiment, the bottom 102 can be connected to the outer wall or inner wall of the body 101. In one embodiment, the bottom 102 is connected to the inner wall of the body 101. In another embodiment, the bottom 102 is connected to the body 101 via a second locking member 130, that is, the bottom 102 is sandwiched between the inner wall of the body 101 and the second locking member 130, and a stable connection is achieved by locking the three together with fasteners. In other embodiments... The bottom 102 of the bucket can also be connected to the inner wall of the body 101 via a connector 140. That is, the bottom 102 of the bucket is sandwiched between the inner wall of the body 101 and the connector 140, and the three are locked together by fasteners to achieve a stable connection. The connector 140 can be, for example, a metal or plastic plate. For example, in one embodiment, the connector 140 is set as a PP plate, and the fastener can be a bolt, etc. With this setting, the bottom 102 of the bucket is sandwiched between the inner wall of the body 101 and the connector 140, and the connection effect is better. In one embodiment, the connector 140 and the second locking member 20 can be set as the same component. This setting can reduce costs and has a good overall fixing effect.

[0043] In this embodiment, the opening 102a is connected to a flange 102b or a pipe fitting. With this arrangement, since the flange or pipe fitting is usually made of metal and has a large weight, when the bottom 102 of the tank is placed in water, the weight of the flange or pipe fitting can make the opening 102 located at the bottom of the entire breeding tank 100, which is conducive to the sedimentation of waste into the opening 102 for discharge.

[0044] In this embodiment, the first support member 100a is disposed on the first locking member 120. In one embodiment, at least a portion (outer protrusion 122) of the first locking member 120 protrudes from the outer wall of the barrel body 101 to form the first support member 100a. With this arrangement, the aquaculture barrel 100 can be supported on the floating platform 300 through the radial protrusion 121. In one embodiment, the first locking member 120 is provided with a hook (not shown in the figure). The hook can facilitate the hoisting of the entire aquaculture barrel out of the water for easy maintenance.

[0045] In this embodiment, the second support member 100b is disposed inside the breeding tank. In one embodiment, it is disposed at the bottom of the tank body 101, for example, at the connection or junction of the tank body 101 and the tank bottom 102. In another embodiment, at least a portion (the inner protrusion) of the second locking member 130 protrudes from the inner wall of the tank body 101 to form the second support member 100b. In another embodiment, the second support member 100b may be configured as a plurality of support frames spaced apart along the circumference of the tank body 101. The support frames may be connected to the second locking member 130, the inner wall of the tank body 101, or the aforementioned connecting member 140. In one embodiment, the second support member 100b is connected to the second... The locking member 130 is used to lock the second support member 100b to the second locking member 130 by fasteners. In one embodiment, the fasteners lock the second support member 100b, the second locking member 130, the bottom of the bucket 102, and the body of the bucket 101 at the same time. This setting is reasonable in fastener setting, the locking is stable and the cost is low. The support frame can be, for example, an angle iron. In another embodiment, the second support member 100b can also be an annular ring, which can be connected to the second locking member 130 or the inner wall of the body of the bucket 101 or the aforementioned connecting member 140. In this setting, the second support member 100b can better support the fish-driving board 200 placed in the breeding bucket 100.

[0046] In this embodiment, the breeding tank 100 may also be provided with a separate water inlet hole, through which external water can exchange with the water inside the breeding tank 100. In one embodiment, multiple plates 110 are provided with water inlets, which can directly guide water into the breeding tank or be used to install water inlet components to guide water into the breeding tank.
