Description

Technical Field

[0001] This invention belongs to the technical field of recirculating aquaculture equipment, specifically relating to the structure of a complete life cycle recirculating aquaculture breeding experimental system. Background Technology

[0002] Current fish farming mainly considers the economic benefits generated by the farming. Therefore, when farming, fry that have grown to a certain stage are usually purchased directly from outside and put directly into the farming. That is, the fry are raised directly into adult fish. In order to maximize economic benefits, multiple farming containers are set up. Multiple farming containers are used for production and occupy a relatively large space.

[0003] This type of aquaculture system, or system designed for production purposes or a single production stage, is characterized by high production volume and strong single-function characteristics. However, it has the following specific disadvantages:

[0004] It is uneconomical, water-inefficient, and energy-inefficient. A single system faces a long breeding cycle, and the system is generally configured according to the maximum load in the later stage of breeding. This will inevitably lead to some equipment being idle in the early stage of breeding, or excessive ineffective energy consumption in the early stage of breeding.

[0005] Not applicable. A single system cannot meet the needs of different growth stages, including variations in aquaculture management, water quality, and aquaculture facility structure.

[0006] It cannot meet the needs of breeding experiments. The number of individual units is too small to meet the large number of independent and controllable units required in breeding experiments.

[0007] A simple list of various categories of systems requires a large area, is uneconomical, and makes breeding management difficult. Summary of the Invention

For systems with the same water quality, they are designed to be shared, resulting in high system utilization. Different stages of aquaculture with the same size and different uses share aquaculture facilities, resulting in high facility utilization.

[0068] Throughout the entire cycle, all systems were designed in a circulating water mode, saving water and energy. While meeting experimental requirements, the land use space was greatly improved.

[0069] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0079] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0080] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0081] This invention proposes an embodiment of a complete life-cycle recirculating aquaculture experimental system, comprising:

[0082] The fish egg hatching module 100 includes multiple independent fish egg hatching and breeding systems 110. Each fish egg hatching and breeding system 110 includes a fish egg hatching box 113 and a fish egg hatching water treatment system 120 connected to it.

[0083] To reduce space requirements and achieve multi-layered, three-dimensional aquaculture, the fish egg incubation box 113 is configured in some embodiments as follows: The fish egg incubation system includes:

[0084] Fish egg incubation rack;

[0085] Multiple support members 112 are arranged on the fish egg incubation rack, arranged from top to bottom along the height direction of the fish egg incubation rack.

[0086] An accommodating space is formed between adjacent load-bearing support members 112.

[0087] Multiple sets of fish egg incubation boxes 113 are provided and arranged in the multi-layered containment space. An operating space 114 is formed between the top of the fish egg incubation box 113 and the upper layer support member 112 to facilitate observation and operation.

[0088] The operating space 114 between the fish egg incubation box 113 and the upper support 112 allows the breeder to conveniently observe and remove dead eggs in the original position.

[0089] Since the fish egg incubation box 113 is installed on the support member 112, it can be removed if needed, and then put back after a short operation.

[0090] Multiple fish egg incubation boxes 113 are provided in each group and are evenly arranged on the corresponding layer's support member 112 along the length of the fish egg incubation rack.

[0091] The fish egg incubation pipeline system is connected to multiple sets of the fish egg incubation boxes 113.

[0092] In some embodiments of this application, the fish egg hatching pipeline system includes:

[0093] Fish egg incubation water inlet pipe and fish egg incubation water return pipe, wherein the fish egg incubation water inlet pipe includes:

[0094] Main water inlet pipe;

[0095] Multiple sets of branch water inlet pipes connected to the main inlet pipe are provided, and the branch water inlet pipe sets are respectively arranged below the multi-layer fish egg incubation box 113.

[0096] Main return water pipe;

[0097] And there are multiple sets of branch return water pipe groups connected to the main return water pipe, which are respectively arranged above the multi-layer fish egg incubation box 113.

[0098] Each set of return water pipes includes multiple return water pipes, which are connected to the upper part of multiple fish egg incubation boxes 113 on the corresponding layer.

[0099] In this embodiment, the water inlet method of the fish egg incubation system is set to bottom inlet and top outlet, which can both properly rinse the fish eggs and prevent them from being disturbed.

[0100] The fish egg hatching water treatment system 120 includes existing structures such as a fish egg biological integrated treatment tank and a water pump. The water pump draws water from the return water pipe into the fish egg biological integrated treatment tank for a series of comprehensive treatments such as filtration and sterilization. Then, the water is sent into the fish egg hatching box 113 through the main inlet pipe for recycling.

[0101] The fish egg incubation water treatment system 120 can be installed below the fish egg incubation rack, reducing the space occupied by the external space.

[0102] The fish egg hatching water treatment system 120 also includes a water temperature regulating tank, on which a plate heat exchanger is connected to regulate the water temperature so that the water flow delivered can meet the constant water temperature required for fish egg hatching.

[0103] In this embodiment, the fish egg hatching system is set up in multiple groups side by side, and each group includes a multi-layered fish egg hatching box 113 structure, so that the entire fish egg hatching system is a three-dimensional multi-layered structure with a small overall space occupation. Within the effective space, a large number of fish eggs are hatched, realizing intensive aquaculture.

[0104] The juvenile fish rearing system 200 is used to raise fish hatched from the fish egg incubation box 113, and is equipped with an independent juvenile fish recirculating water treatment system 300 connected to it.

[0105] After hatching from the fish egg incubation box 113, the fish are transferred to the juvenile fish rearing system 200 for further rearing.

[0106] The juvenile fish rearing system 200 and the fish egg hatching module 100 are arranged adjacent to each other.

[0107] Since the water conditions required for raising juvenile fish are different from those for fish eggs and other stages of fish, this embodiment sets up a separate juvenile fish farming system 200 for raising juvenile fish separately. The juvenile fish recirculating water treatment system 300 may include a multi-stage biological treatment tank and a temperature regulation tank and an ultraviolet sterilization and disinfection tank connected to the output end of the multi-stage biological regulation tank, so as to achieve comprehensive treatment of the water quality used for raising juvenile fish.

[0108] The existing structure can also be used for the juvenile fish recirculating water treatment system 300.

[0109] The juvenile fish rearing system 400 is used to rear the fish transferred from the juvenile fish rearing system 200;

[0110] After the fry have been raised in the juvenile fish rearing system 200, they can be transferred to the young fish rearing system 400 for further rearing.

[0111] The preferred juvenile fish rearing system 400 is arranged adjacent to the juvenile fish rearing system 200.

[0112] The adult fish farming system 500 is used to farm fish transferred from the juvenile fish farming system 400;

[0113] Fish that have completed their rearing in the juvenile fish rearing system 400 will be transferred to the adult fish rearing system 500 for further rearing, where they will grow into adult fish.

[0114] The adult fish farming system 500 and the juvenile fish farming system 400 share a common juvenile and adult fish recirculating water treatment system 600;

[0115] Since the aquatic environment required for juvenile and adult fish farming is basically the same, this embodiment allows juvenile and adult fish to share a single juvenile-adult fish recirculating water treatment system 600, which simultaneously treats the water quality in the juvenile fish farming system 400 and the adult fish farming system 500, reducing the space occupied and the required treatment equipment, and lowering costs.

[0116] The transfer track module is arranged between the fish egg hatching module 100, the fry rearing system 200, the fry recirculating water treatment system 300, the juvenile fish rearing system 400, the adult fish rearing system 500, and the juvenile-adult recirculating water treatment system 600, so as to facilitate the transfer of fish eggs or fry at different stages between the various systems and modules.

[0117] The water quality parameter detection component is equipped with multiple sets, which are used to detect water quality parameters in the fish egg hatching box, juvenile fish rearing system, young fish rearing system and adult fish rearing system respectively;

[0118] The controller connects to multiple water quality detection components to acquire water quality parameters in different aquaculture systems.

[0119] It also communicates with the fish egg hatching water treatment system, the juvenile fish recirculating water treatment system, and the juvenile and adult fish recirculating water treatment system to obtain the equipment parameters of each system;

[0120] The display screen, connected to the controller, can at least display water quality parameters and parameters of various system equipment. Setting up transfer tracks between the various aquaculture systems and modules facilitates observation of the fish fry in each system. When fish need to be transferred or separated, transfer equipment can be installed on the transfer track modules to facilitate the transfer and separation of fish fry.

[0121] The complete life cycle recirculating aquaculture experimental system in this embodiment is designed to meet the different environmental requirements of fish farming at different stages. Different farming systems and matching water circulation treatment systems are set up separately for each stage. For example, when fish eggs are hatching, each fish egg hatching and farming system 110 is equipped with its own corresponding fish egg hatching water circulation system. For juvenile fish farming, the environment and water temperature required are different from other stages, so a separate juvenile fish water circulation treatment system is set up.

[0122] For juvenile and adult fish with similar water temperatures and environments, a single recirculating water treatment system is used. Each stage of the aquaculture process, with varying water and quality conditions, is equipped with an independent recirculating water treatment system, while stages with similar conditions share a single system, thus enabling individual control of the aquatic environment.

[0123] The complete life cycle recirculating aquaculture experimental system can realize the entire life cycle of fish farming from spawning to adulthood. Specifically, during farming, adult fish are raised as broodstock in the adult fish farming system 500; after spawning, they are transferred to the fish egg hatching system; the hatched fry are raised in the juvenile fish farming system 200; the well-raised juveniles are then transferred to the juvenile fish farming system 400 for further cultivation; and then transferred to the adult fish farming system 500 to grow into adult fish, completing the first generation of complete life cycle breeding experimental process, thus realizing full life cycle farming.

[0124] Throughout the entire fish fry rearing process, from egg to adult fish, a recirculating water treatment system is used for different stages of fish fry rearing. Furthermore, juvenile fish and adult fish share the same recirculating water treatment system, achieving highly efficient water and energy conservation.

[0125] The water quality parameter detection component in this embodiment may include a water temperature sensor, a salinity sensor, a dissolved oxygen sensor, an ammonia nitrogen sensor, and a pH sensor, for detecting different water quality parameters.

[0126] The parameters can be displayed on the screen connected to the controller, allowing users to intuitively observe parameter changes.

[0127] If the parameter exceeds the set value, the controller will send a signal to the alarm device to notify the user when it detects that the corresponding value has exceeded the limit.

[0128] The controller can also be wirelessly connected to a user terminal APP. Users can download the user terminal APP to their mobile phones or other devices and send messages and notifications to the user terminal APP through the controller.

[0129] The controller can also detect the parameters of the corresponding water treatment equipment in each circulating water treatment system and display them on the screen.

[0130] During use, users can also manually touch the display screen to input control commands or modify parameters.

[0131] Human-computer interaction was achieved through the display screen.

[0132] In some embodiments of this application, a fish egg storage module is also included, which is used to temporarily store fish eggs. The fish egg storage module is a fish egg storage pool, in which fish eggs squeezed out from adult fish can complete fertilization.

[0133] In some embodiments of this application, in order to reduce the space occupied by the entire full life cycle recirculating aquaculture experimental system, multiple independent fish egg hatching and breeding systems 110 are arranged in parallel along the first direction during the layout.

[0134] The fish egg hatching module 100, the juvenile fish rearing system 200, the young fish rearing system 400, and the adult fish rearing system 500 are arranged sequentially along the second direction;

[0135] The juvenile fish recirculating water treatment system 300 and the juvenile and adult fish recirculating water treatment system 600 are arranged on one side of the fish egg hatching module 100, the juvenile fish rearing system 200, the juvenile fish rearing system 400 and the adult fish rearing system 500, with the second direction perpendicular to the first direction.

[0136] Arranging the fish egg hatching module 100, the juvenile fish rearing system 200, the young fish rearing system 400, and the adult fish rearing system 500 in a sequential, side-by-side configuration allows for a compact structural layout among the systems, minimizing space requirements.

[0137] In some embodiments of this application, the juvenile fish rearing system 200 includes:

[0138] It includes multiple sets of juvenile fish rearing containers arranged side by side along the second direction, and each set of juvenile fish rearing containers includes multiple juvenile fish rearing containers 210 arranged along the first direction.

[0139] The 210 sets of juvenile fish rearing containers can be arranged in two or three groups side by side.

[0140] Each group may include multiple juvenile fish rearing containers 210. There may be 10 juvenile fish rearing containers in one group, and two groups may be arranged together.

[0141] The juvenile fish recirculating water treatment system 300 is connected to the multiple sets of juvenile fish rearing containers 210.

[0142] During setup, each group of juvenile fish rearing containers 210 is equipped with multiple juvenile fish inlet water pipes and multiple juvenile fish outlet water pipes, which are respectively connected to multiple juvenile fish rearing containers 210.

[0143] The juvenile inlet water pipes and juvenile return water pipes of the multiple juvenile rearing containers 210 are respectively connected to the juvenile main inlet water pipe and the juvenile main return water pipe.

[0144] In some embodiments of this application, the juvenile fish rearing container 210 includes:

[0145] base body 211;

[0146] The barrel 212 is detachably assembled onto the base 211, and a barrel 212 space is formed inside the barrel 212.

[0147] The base 211 includes:

[0148] The base body has an insertion space formed within it;

[0149] Supporting protrusions are formed by protruding from the bottom of the base body, and multiple protrusions are arranged circumferentially along the base body.

[0150] The barrel 212 is placed in the insertion space and its bottom fits against the support protrusion.

[0151] An annular mounting portion is provided in the middle of the seat body, and an insertion portion is formed at the bottom of the barrel 212. The barrel 212 is inserted into the annular mounting portion through the insertion portion. The annular mounting portion is an annular mounting sleeve. When the barrel 212 is placed inside the seat body, it is inserted into the annular mounting sleeve through the insertion portion at the bottom.

[0152] Multiple breeding equipment 213 are provided, arranged inside the barrel 212 and detachably connected to the barrel 212;

[0153] The breeding apparatus 213 is equipped with an insertion post, and an insertion hole is provided on the barrel 212. The breeding apparatus 213 is inserted into the insertion hole through the insertion post. In use, the insertion post can be inserted into the insertion hole on the top surface of the side wall of the barrel 212 to achieve connection with the barrel 212. When disassembling, the insertion post can be pulled out from the insertion hole.

[0154] Each of the breeding devices 213 has an independent breeding space inside, and the breeding devices 213 are provided with mesh holes to allow the breeding space to communicate with the space of the barrel 212.

[0155] Since the fry are small, to prevent them from colliding with each other, they can be raised in several smaller breeding containers 213. Furthermore, raising them in breeding containers 213 also makes it convenient to transfer them when they reach the required size. During transfer, the breeding containers 213 can be directly removed from the barrel 212 and transferred to the fry breeding system 400.

[0156] A return water pipe section 214 is arranged inside the barrel 212 and extends outward from the seat 211 from the barrel 212. It is sealed to the barrel 212. The return water pipe section 214 is provided with a return water part that draws water from the barrel 212 into the return water pipe section 214.

[0157] The return water section consists of spirally arranged spiral return water holes formed on the wall of the return water pipe section 214. Multiple spiral return water holes are provided and arranged along the height direction of the wall of the return water pipe section 214.

[0158] In some embodiments of this application, a connecting component 215 is provided between the barrel 212 and the return water pipe section 214 to connect the barrel 212 and the return water pipe section 214, thereby achieving a sealed connection between the barrel 212 and the return water pipe section 214.

[0159] The connecting component 215 is arranged at the insert portion, and a closed filling cavity 216 is formed between the connecting component and the insert portion, and the filling cavity 216 is filled with expanding foam.

[0160] The insert and the connecting assembly 215 are connected and sealed by filling the filling cavity 216 with a foam cavity.

[0161] The insertion part has an insertion cavity with openings at both ends. The top opening connects to the space of the barrel 212, and the bottom opening has a diameter smaller than the inner diameter of the insertion cavity. The connecting assembly 215 includes:

[0162] The threaded connector 2151 has a limiting stop 2152 formed at its end and an external thread formed on its exterior. The threaded connector 2151 extends into the insertion cavity through the bottom opening of the insertion part, and the limiting stop abuts against the outer side of the bottom wall of the insertion part.

[0163] The limiting stop part 2152 is a limiting stop rib, which is used to limit the threaded connection.

[0164] Locking member 2153 is located within the installation space and is screwed and fixed to threaded connector 2151;

[0165] The locking member 2153 has an internal thread, which is screwed onto the threaded connector 2151 to connect the threaded connector and the barrel 212.

[0166] The elastic seal 2154 is sleeved on the threaded connector 2151 and pressed between the locking member 2153 and the inner side of the bottom wall;

[0167] The elastic seal is an elastic sealing ring, which is used to achieve a seal.

[0168] The sealing component 2155 is used to seal the top opening of the insertion part, is screwed onto the threaded connector 2151 and is located above the locking component, and its top surface is basically flush with the bottom wall of the barrel body 212.

[0169] The barrel body 212 includes a bottom wall, which is arranged at an angle from the outer edge of the barrel body 212 toward the center of the barrel body 212. The height of the point at the center of the barrel body 212 is lower than the height of any point on the bottom wall of the barrel body 212, that is, the bottom of the barrel body 212 is conical, with the middle position being the lowest.

[0170] Because the bottom wall of the bucket 212 is inclined, the excrement and residual food in the bucket 212 will gather towards the center of the bucket 212. By placing the return water pipe in the center, a large amount of excrement and residual food can be recycled into the return water pipe.

[0202] Furthermore, it achieves the requirement of large-scale breeding while occupying little space;

[0203] The complete life cycle recirculating aquaculture experimental system in this embodiment realizes the cyclical aquaculture of the entire life cycle from broodstock - egg hatching - fry rearing - juvenile rearing - adult fish rearing - broodstock - respawning and hatching, and is equipped with multiple corresponding aquaculture systems and associated recirculating aquaculture systems. The structure of each sub-aquaculture system is rationally designed so that the design of each subsystem meets the personalized, independent, controllable water body and space requirements of the breeding experiment;

[0204] Each aquaculture system includes multiple sets of aquaculture containers, allowing fish fry to form independent and controllable compartments in each container, facilitating differentiated observation, marking, and generational differentiation in breeding experiments.

[0205] The aquaculture systems are matched in terms of water volume. For systems with the same water quality, they are designed to be shared, resulting in high system utilization. Different stages of aquaculture with the same size and purpose share aquaculture facilities, resulting in high facility utilization.

[0206] Throughout the entire cycle, all systems are designed in a circulating water mode, which saves water and energy.

[0207] The fish egg incubation system adopts a three-dimensional multi-layer incubation box structure. The juvenile fish rearing system 200, the young fish rearing system 400, and the adult fish rearing system 500 are all arranged in multiple groups side by side, which greatly improves the land use space while meeting the experimental quantity requirements.
