Description

Technical Field

[0001] The utility model relates to the field of marine engineering equipment, in particular to a modular deep-sea aquaculture cage and an aquaculture system based on modular assembly. Background Art

[0002] In recent years, the decline of offshore fishery resources due to overfishing and environmental pollution has become a global problem. Expanding aquaculture into deepwater and deep-sea waters has become an inevitable trend, with aquaculture gradually shifting from nearshore to deep-sea areas. As an effective marine aquaculture method, aquaculture cages have been widely used and developed around the world.

[0003] Modular and standardized production methods will help promote the industrialization and large-scale development of deep-sea aquaculture cages. However, existing modular aquaculture cages still have the following defects:

[0004] (1) For example, the modular space truss structure deep-sea cage disclosed in Chinese patent CN202010759252.8 uses a dense steel structure as the cage body. Its installation structure is complex, the degree of standardization is not high, and it is not convenient for transportation and assembly, which is not conducive to on-site assembly and deployment of aquaculture cages. In addition, its lifting method adopts a suspended type, and the lifting accuracy of the aquaculture cage body is uncontrollable. It is easily affected by extreme weather such as typhoons, causing the main structure of the cage to be deformed by sea flow.

[0005] (2) Secondly, modular and standardized product production inevitably leads to the reduction of the size of single modules, which puts higher requirements on the connection accessories between the pile legs and the frame system. The existing aquaculture cages fail to meet the requirements of high modularity and high standardization in terms of connection accessories.

[0006] (3) In terms of the expansion of aquaculture volume / capacity, the existing aquaculture cages can only be expanded by increasing the volume of the cages, but this will lead to problems such as insufficient strength. Therefore, the rapid expansion of aquaculture capacity needs further development and research. Utility Model Content

[0090] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0091] like Figure 1-40 As shown, the rack and pinion lifting aquaculture cage is an advanced modular deep-sea aquaculture cage, which includes pile legs 1, a lifting installation unit 2, a modular cage body 3, and a rack and pinion lifting unit 4. The modular cage body 3 is controlled by the rack and pinion lifting unit, so that the cage body can be freely lifted and lowered along the pile legs on the water surface and underwater, realizing functions such as aquaculture in specific water layers and typhoon protection.

[0092] In order to realize modular and standardized production of aquaculture cages, this application designs one or more assembly parts such as pile legs, cage bodies, lifting and installation units into modular and standardized assembly parts. The assembly parts of the entire aquaculture cage are highly universal, meeting the requirements of rapid installation and high transportability of assembly parts, with low transportation costs.

[0093] Specifically, this application achieves modular installation by designing modular pile legs, which are composed of multiple detachable and assembled pile leg units. This greatly simplifies the transportation and installation process of the pile legs and reduces transportation and installation costs. In addition, the modular pile legs are designed with annular mounting rings, limit holes, markers and other structures at the pile leg joints to achieve disassembly and connection, making the pile legs recyclable, facilitating pile leg replacement and maintenance, and also solving the problem of tooth connection and alignment at the pile leg joints.

[0094] The present application also provides several lifting and installation units. Due to the modular design concept, the lifting and installation units between the same-shaped cage bodies are universal, which improves the universality of the modular cage body assembly parts. The lifting and installation units between the different-shaped cage bodies can be selected according to the shapes of different cage bodies and the assembly structure of the modular cages to meet the installation needs of cage bodies with various shapes, improve the applicability of the modular cage body assembly parts, realize modular and standardized batch factory production, ensure production accuracy and facilitate transportation, and facilitate on-site assembly and cage deployment.

[0095] In addition, the cage body in the present application is a cage-shaped space truss structure, which is specifically modularly constructed and expanded by several cage surface modules. The horizontal cross-sectional shape of the cage body can be various, such as triangle, U-shaped, sun-shaped, field-shaped, quadrangular, pentagonal, hexagonal, octagonal, etc., or it can be assembled in sequence from multiple separate "U-shaped" modular cages, such as double-mouthed, triple-mouthed, multi-mouthed, etc., or it can be assembled in sequence from multiple separate "sun-shaped" modular cages, such as four-mouthed, six-mouthed, eight-mouthed, etc. Figure 2a-h as shown.

[0096] The structure of the modular deep - sea aquaculture cage with various different shapes of the present utility model is further described as follows:

[0097] Embodiment 1: "Square - shaped" modular deep - sea aquaculture cage

[0098] As <00002​​​​​​​​​​​​​In the selection of the lifting installation unit, the "mouth"-shaped modular deep-sea aquaculture cage 100 of this embodiment adopts eight lifting installation units 2-2. There are two installation components 23 on each lifting installation unit 2-2, which are used to install two side modules. The installation components 23 include a first installation component 23-1 and a second installation component 23-2. The first installation component 23-1 installs one of the side modules, and the second installation component 23-2 installs the other side module. The first installation component 23-1 and the second installation component 23-2 are distributed at a 90° angle and are staggered with each other on the same horizontal plane as the two second cavities / racks. Figure 6 shown.

[0102] Specifically, each of the mounting components 23 includes a horizontal mounting portion 231 and an inclined mounting portion 232. The first mounting component is briefly described as an example. Figure 7 As shown, the first mounting assembly 23-1 includes a horizontal mounting portion 231 and an inclined mounting portion 232. The horizontal mounting portion 231 is arranged along the radial direction on the outer wall of the outer ring portion of the lifting mounting unit, and the inclined mounting portion is inclinedly arranged on the upper edge of the outer ring portion of the lifting mounting unit (applicable to the lifting mounting unit of the upper cage body, such as Figure 7 As shown) or the lower edge (applicable to the lifting installation unit of the lower cage body, such as Figure 9 As shown), different lifting installation nodes are selected according to the installation requirements of the cage body; the horizontal installation portion 231 and the inclined installation portion 232 on each of the installation components are located on the same vertical plane.

[0103] As a further preferred solution, each of the first lifting installation unit 2-1, the second lifting installation unit 2-2, the third lifting installation unit 2-3, and the fourth lifting installation unit 2-4 includes an annular installation section body, each annular installation section body includes an outer ring panel 24, an inner ring panel 25, a horizontal panel 26, a reinforcing plate 27, and a sliding sheet 28; the outer ring panel 24 is upright, the inner ring panel 25 is concentrically arranged on the inner side of the outer ring panel 24, the outer side of the outer ring panel 24 forms the outer ring portion, and the inner ring surface The inner side of the plate 25 forms the inner ring portion 21; multiple horizontal panels 26 are horizontally supported between the outer ring panel 24 and the inner ring panel 25; multiple horizontal panels 26 divide the lifting and installation unit into multiple hollow chambers; multiple reinforcing plates 27 are uprightly arranged, and multiple reinforcing plates 27 are radially distributed between the outer ring panel 24 and the inner ring panel 25; multiple sliding sheets 28 are evenly distributed on the inside of the inner ring panel 25, and the contact area between the sliding sheets 28 and the pile legs is smaller than the contact area between the inner ring panel 25 and the pile legs.

[0104] Optionally, the outer ring portion of the lifting installation unit 2 is further provided with a pin connection member 210, such as Figure 8 shown.

[0105] As a further preferred solution, Figure 14-20 As shown, the pile leg 1 of this embodiment is a modular pile leg, comprising at least two pile leg units 12, each of which is a hollow tube body, and the racks 11 extend outwardly on both sides of the hollow tube body along the tube diameter direction; the adjacent two pile leg units are detachably connected, and an annular mounting plate 121 is provided at the connection of each of the pile leg units, and the annular mounting plate is formed by extending from the inner wall of the hollow tube body toward the center position along the radial direction, and each annular mounting plate is provided with a plurality of limiting through holes 122, and the positions of the limiting through holes of the annular mounting plates at the connection of the two adjacent pile leg units correspond one to one, and the two annular mounting plates are stacked on each other and fastened with the limiting through holes by a fastening connector (not shown in the figure) to fix the two adjacent pile leg units in connection, and the rack between the two adjacent pile leg units extends along the axial direction of the tube body.

[0106] The design and manufacture of pile legs need to take into account multiple factors, including their strength, stability, corrosion resistance, and maintainability. To this end, this application designs the pile legs to be detachably connected. Specifically, two stacked annular mounting plates are designed on the pile leg units, and limiting through holes and fastening connectors are designed on the annular mounting plates. When the annular mounting plates are locked together, the two pile leg units can be fixedly connected. When the pile legs need to be replaced or repaired, there is no need for extensive welding and cutting work, which improves the efficiency of disassembly and assembly and reduces maintenance costs.

[0107] However, since the modular pile legs are used in a gear-type lifting transmission device, in addition to achieving a fixed connection between the two pile legs, it is also necessary to consider the connection of the teeth on the adjacent pile leg units to achieve the up and down lifting function of the entire net box body. In order to solve the above problems, the present application also designs multiple positions and numbers of limiting through holes on the annular mounting plate. During the on-site assembly process, by adjusting the alignment of the limiting through holes, the teeth of the two pile leg units can be connected to ensure the up and down lifting function of the net box body.

[0108] As can be seen, the present application designs the pile legs into modular pile leg units, which are easy to disassemble and assemble, reducing the transportation volume and lowering the transportation cost. When the pile legs need to be replaced or repaired, there is no need for a large amount of welding and cutting work, which improves the efficiency of disassembly and assembly and reduces maintenance costs. The required height of the pile legs can be flexibly adjusted according to the actual working conditions. The advantage of this technical solution is that it improves the flexibility and convenience of the self-elevating cage. In addition, it also solves the problem of the mutual connection of the teeth of the two pile leg units, ensuring the up and down lifting function of the cage body.

[0109] As a further preferred embodiment, a central opening 123 is provided in the middle of each of the annular mounting plates, and a marker 124 is provided near the connection portion of each of the leg units for locating the direction of the rack so as to facilitate the connection between two adjacent sections of the rack; the marker is one or a combination of two or more of an opening, a through hole, a butt joint, a groove, and a protrusion.

[0110] This application designs a central opening on the annular mounting plate to facilitate the timely and rapid observation of the connection between the teeth on the surface of the pile legs during the assembly process, and to facilitate the adjustment of the alignment between the multiple limit holes between the two pile legs, thereby achieving rapid assembly and disassembly of the pile legs. Figure 16-17 As shown, two adjacent leg units are provided with two marker openings 124 near the connection, and the two marker openings 124 are located on the same side wall of the pipe body and on the same axis. When the two leg units are installed or assembled, the two marker openings 124 are adjusted to be located on the same side of the pipe body and on the same axis. Subsequently, the annular mounting plates at the connection of the two leg units are stacked on each other. At this time, the limit through-holes on the two annular mounting plates are aligned with each other. Finally, the two leg units are locked together by fastening connectors such as locking bolts to achieve a fixed connection. In addition, designing the marker into an open shape has another advantage. That is, when the leg is installed in the mud, the design of the marker opening 124 helps to improve watertightness and reduce the impact of water on the leg.

[0111] As a further preferred solution, the leg units located at the bottom layer are the primary supporting and load-bearing components of the entire cage. To this end, this solution incorporates multiple features to enhance leg strength, specifically increasing axial and radial support forces at multiple locations, including the bottom and middle of the legs. Specifically, the bottom portion of the leg units located at the bottom layer serves as the mud entry portion 125, with several annular reinforcement plates 126 provided on the tubular body at the mud entry portion to increase its strength. The inner wall of the central tubular body of the leg units located at the bottom layer is provided with a reinforcement plate 127, which is equipped with multiple radially distributed reinforcement ribs 128.

[0112] In this embodiment, multiple annular reinforcement plates are designed within the lowermost mud-entering portion of the pipe body. These plates are evenly distributed along the inner wall of the pipe body, eliminating or reducing the radial compressive force exerted by the mud on the pile legs during installation. Furthermore, the central portion of the annular reinforcement plates is provided with openings. As the pile legs are pressed downward, seabed sediment rushes into the legs, generating negative pressure and fixation after reaching a certain depth. The openings in the lower portion of the legs are designed to allow mud to enter the legs during the downward pressure, thereby increasing the grip of the legs on the ground. Furthermore, a reinforcement plate and radial reinforcement ribs are designed in the middle of the lowest leg unit, enhancing the strength of the central portion of the leg unit, enabling the legs to effectively withstand the challenges of the marine environment, such as the impact of ocean currents on the legs.

[0113] As a further preferred embodiment, the racks 11 on the bottom-most leg units have two different thicknesses: a thick rack 111 and a thin rack 112. The thickness of the racks on the upper leg units is greater than that on the lower leg units; the thickness of the racks on the upper leg units is the same as that of the upper racks on the bottom-most leg units. This effectively improves the upward bearing capacity of the legs above the mud and meets the climbing force requirements of the entire cage body on the legs. Furthermore, the legs entering the mud do not need to bear the upward bearing capacity of the cage body. Designing different rack thicknesses in different locations helps reduce the material cost of the legs.

[0114] like Figure 21-27 As shown, in this embodiment, the cage surface modules include three types: side modules 31, bottom modules 32, and top modules 33; wherein, the side modules 31 are located on the side of the modular cage body 3, and are used to form the side of the cage-shaped space truss structure; the bottom module 32 is located on the bottom surface of the modular cage body 3, and is used to form the bottom of the cage-shaped space truss structure; the top module is located on the top surface of the modular cage body 3, and is used to form the top of the cage-shaped space truss structure; the three cage surface modules are mutually enclosed to form a cage-shaped space truss structure.

[0115] Among them, the side module 31 includes an upper crossbeam 311, a lower crossbeam 312, and a diagonal brace assembly 313; the upper crossbeam 311 and the lower crossbeam 312 are arranged parallel to each other, and the diagonal brace assembly 313 is detachably installed between the upper crossbeam 311 and the lower crossbeam 312; the diagonal brace assembly 313 is spliced ​​by multiple diagonal braces, and the multiple diagonal braces are connected in a detachable manner; the diagonal brace assembly 313 is a combination of one or more shapes selected from V-shape, inverted V-shape, W-shape, inverted W-shape, and X-shape.

[0116] This embodiment designs multiple crossbeam tubes and diagonal bracing tubes, which are assembled into a surface module in a detachable manner. The various tube parts are highly standardized, and each surface module can be independently assembled, maintained and repaired, which shortens the construction time. This reduces the difficulty of overall assembly and maintenance required for the one-piece welded cage in the prior art, and at the same time simplifies maintenance and expansion, thereby extending the service life of the aquaculture cage.

[0117] As a further preferred embodiment, the diagonal brace assembly 313 includes a long diagonal brace 3131 and / or a short diagonal brace 3132; both ends of the long diagonal brace 3131 and the short diagonal brace 3132 are provided with a pin connector 315, and the upper crossbeam 311, the lower crossbeam 312 and the diagonal brace assembly 313 are connected with a pin connector 315, and the above-mentioned pin connector 315 shares the same size of pins for installation, and the upper crossbeam 311, the lower crossbeam 312, the long diagonal brace 3131 and the short diagonal brace 3132 are quickly assembled through the pin connector 315 and the pin 316. In this example, the diagonal brace assembly 313 includes three long diagonal braces 3131 and six short diagonal braces 3132. Every two short diagonal braces 3132 are detachably connected to the middle position of a long diagonal brace 3131 through the pin and the pin connector 315 to form three X-shaped assemblies. Preferably, the long diagonal brace 3131 is supported on both sides of the side module 31 to increase the strength of the force point; the pin connector 315 is a standard part, and includes a fixed connection part 3151 and a hanging ear part 3152 connected to the fixed connection part; the pin is passed through the hanging ear part 3152.

[0118] In each face module of this example, the upper and lower cross beams 311 / 312, diagonal braces and other pipe body connections are fixed to each other by means of pins, thereby speeding up the construction of the aquaculture cage, reducing errors in manual construction, and also reducing labor costs. The pin connectors 315 used in the side modules 31 of this application are all designed at both ends of the pipe body or on the side of the pipe body, and basically include a fixed connection part 3151 and a hanging ear part 3152; the installation between the two pin connectors 315 is also very simple, and they can be quickly connected through the same size pin 316. Therefore, the pin connectors 315 of this application can be designed as universal parts or standard parts according to actual conditions, which can reduce the cost of accessory development and increase assembly speed.

[0119] As a further preferred embodiment, the side modules 31 further include risers 314 for strengthening the connection strength of the side modules 31; the risers 314 are connected between the upper crossbeam 311 and the lower crossbeam 312 and / or between the diagonal brace assemblies 313. The present application designs the risers 314 so that, depending on actual needs, they are fixed to the side modules with detachable pins or welding. The provision of the risers 314 reduces deformation of the aquaculture cage, improving overall structural strength and wind and wave resistance.

[0120] As a further preferred embodiment, the bottom module 32 includes a bottom crossbeam 321, a cross tube 322, and a bottom diagonal brace 323. Multiple bottom crossbeams 321 are connected end to end to form the bottom outer frame of the aquaculture cage. In this embodiment, the bottom crossbeams 321 are replaced by the lower crossbeams 312 in the side modules 31. Each bottom diagonal brace 323 is detachably connected to two adjacent bottom crossbeams 321. The ends of the cross tubes 322 are detachably connected to the bottom diagonal braces 323. The cross tubes 322 are either integrally formed or comprised of multiple detachably connected tubes.

[0121] This application designs a bottom crossbeam 321, a cross tube 322, a bottom diagonal brace 323, etc., which are assembled into a bottom module 32 in a detachable manner. The above-mentioned pipe parts are highly standardized, the construction time is short, and the maintenance difficulty is reduced. In addition, the bottom crossbeam 321 of the bottom module 32 of this example can also be used together with the lower crossbeam 312 of the side module 31, or can be replaced by the lower crossbeam 312 in the side module 31, which further reduces the consumables of the bottom module 32, further improves the convenience and reliability of the connection between the surface modules, and improves the strength of the aquaculture cage.

[0122] As a further preferred embodiment, the top surface module 33 includes a top crossbeam 331 and a top diagonal brace 332; multiple top crossbeams 331 are connected end to end to form the top outer frame of the breeding cage, and each of the top diagonal braces 332 can be detachably connected to two adjacent top crossbeams 331; or the top crossbeam 331 is replaced by the upper crossbeam 311 in the side module 31.

[0123] The present application designs a top crossbeam 331, a top diagonal brace 332, and the like, which are assembled in a detachable manner to form a top surface module 33. The above-mentioned pipe parts are highly standardized, the construction time is short, and the maintenance difficulty is reduced. In addition, the top crossbeam 331 of the top surface module 33 can also be used together with the upper crossbeam 311 of the side module 31, or can be replaced by the upper crossbeam 311 in the side module 31, which further reduces the consumables of the top surface module 33, further improves the convenience and reliability of the connection between the surface modules, and improves the strength of the aquaculture cage.

[0124] like Figure 28-31As shown, this "mouth"-shaped modular deep-sea aquaculture cage example has four legs, each of which is equipped with two rack-and-gear lifting units 4, located on the racks on either side of the leg and connected to the racks. Both rack-and-gear lifting units 4 are mounted on the same lifting mounting unit; each rack-and-gear lifting unit 4 includes a drive unit 41, with a climbing gear 42 located at the power output of the drive unit 41. The drive unit 41 is fixed to the lifting mounting unit via a mounting base 43.

[0125] As modular and standardized production methods are more conducive to promoting the industrialization and large-scale development of deep-sea aquaculture cages, in order to solve the technical problems of smaller volume of single modules and limited installation space after modular and standardized production, this application improves the installation position and structure of the lifting transmission device. Specifically, by designing the inner and outer ring parts 22 of the lifting installation unit, it can not only meet the needs of the meshing transmission space of the climbing gear 42 to maintain transmission stability, but also meet the installation space needs of the modular cages, thereby ensuring the smooth operation and stability of the rack gear lifting unit throughout the entire aquaculture cycle.

[0126] As a further preferred solution, Figure 31 As shown, the mounting base 43 includes a mounting box 431 and a connecting lug 432 arranged at the bottom of the mounting box 431; the mounting box 431 has a hollow chamber 433 for mounting the climbing gear 42 and an opening 434 for receiving the rack on the pile leg, and the opening 434 is connected to the hollow chamber 433; the driving device 41 is mounted on the mounting box 431, and the climbing gear 42 on the driving device 41 extends into the hollow chamber 433 and engages with the rack on the pile leg; the connecting lug 432 is fixedly mounted on the lifting mounting unit.

[0127] In addition, the lifting and mounting unit 2 is provided with a support base 29 extending from the inner ring portion 21 to the outer ring portion 22. A plurality of crisscrossing reinforcement ribs are added to the support base 29. The two connecting lugs 432 are clamped on the support base 29 and fixedly connected to the support base 29. The support base 29 of the present application is located on the lifting and mounting unit 2 where the inner ring portion 21 extends to the outer ring portion 22. The support base 29 has a certain degree of structural reinforcement and is located at this position. The plurality of crisscrossing reinforcement ribs are added to this position. The structure of the support base 29 can meet the strength requirements of the lifting and mounting unit itself and meet the load-bearing capacity and ocean current impact force required during lifting movement.

[0128] In this embodiment, the mounting base 43 is designed to be box-shaped, which not only meets the need for its own support strength but also meets the need for assembly connection with multiple other functional components. Specifically, it includes the mounting avoidance position for the rack, the mounting position of the climbing gear 42, the mounting position of the lifting motor, and the connecting lug 432 for assembling with the lifting mounting node. The above spatial structure is reasonably designed, with high strength and strong stability.

[0129] As a further preferred solution, the driving device 41 includes a lifting motor 411, a coupling 412, a reduction gearbox 413, and a brake 414. The lifting motor 411 is传动连接(这里原文有误,推测是“drivably connected”) to the reduction gearbox 413 through the coupling 412, and the climbing gear 42 is fixedly installed on the transmission shaft of the reduction gearbox 413. The brake 414 is installed on one side of the lifting motor 411 and is used to emergently stop the lifting motor 411. When the lifting motor 411 suddenly loses power, the brake 414 is triggered to stop the motor operation, reducing the risk of the entire net cage during the lifting operation. Optionally, the brake 414 is selected from the PRECIMA brake 414 of Germany, which is a spring-loaded dry friction electromagnetic brake 414.

[0130] The reduction gearbox 413 of this application is provided with a cycloid reducer and a planetary reducer. The cycloid reducer and the planetary reducer are sequentially arranged at the output end of the lifting motor 411, and the climbing gear 42 is installed on the transmission shaft of the planetary reducer, so as to drive the entire net cage body to lift through a wired or wireless control method, and the lifting is stable.

[0133] Compared with Embodiment 1, the differences of the "day"-shaped modular deep-sea aquaculture net cage in Embodiment 2 lie in the shape of the modular net cage body 3 and certain differences in the selection, structure, and assembly of the lifting installation units 2. The rest are the same as those in Embodiment 1 and will not be repeated here.

[0134] Specifically, the modular cage body 3 is composed of seven side modules 31, two bottom modules 32, and a top module 33. The seven side modules 31 are connected end to end to enclose a modular cage body 3 structure in the shape of a Chinese character 'Ri' (日). In this example, for the selection of the lifting and installation units, eight lifting and installation units two 2-2 and four lifting and installation units three 2-3 are adopted.

The structures and transmission methods of the pile legs 1 and the rack and pinion lifting unit 4 are the same as those in Embodiments 1-2, and will not be repeated here. Specifically, the relevant textual records and related drawings in Embodiments 1-2 are cited.

[0140] Compared with Embodiment 1, the difference of the "field" - shaped modular deep - sea aquaculture cage in Embodiment 3 lies in certain differences in the shape of the modular cage body 3 and the selection, structure, and assembly of the lifting and installation units 2.

[0141] Specifically, the modular cage body 3 is composed of twelve side modules 31, four bottom modules 32, and four top modules 33.

In the selection of the lifting and installation units in this example, eight lifting and installation units two 2 - 2, eight lifting and installation units three 2 - 3, and two lifting and installation units four 2 - 4 are adopted.

The structure of the "mouth"-shaped aquaculture cage is specifically described in Example 1 and will not be repeated here. Each adjacent "mouth"-shaped aquaculture cage is connected and fixed to each other by a pin connector 210 designed on the lifting installation unit, so that they can rely on and connect with each other in the sea area, thereby improving the installation stability of the cage under the seabed. When the aquaculture cage needs to be lifted or lowered, the fixed connection between each aquaculture cage is released by disassembling the pin connector 210, thereby realizing the lifting function of each aquaculture cage. The cage of this type can continuously expand its length horizontally to achieve modular expansion aquaculture.

[0145] Example 5 "Six-port" modular deep-sea aquaculture cage
