Description

Technical Field

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

[0002] In recent years, due to overfishing and environmental pollution, the decline of nearshore fishery resources has become a global problem. Expanding aquaculture in deep-sea and far-sea areas has become an inevitable trend, with aquaculture gradually shifting from nearshore to the deep sea. Cage farming, as an effective method of marine aquaculture, has been widely used and developed globally.

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

[0004] (1) As disclosed in Chinese Patent CN202010759252.8, the modular space truss structure deep-sea cage uses a dense steel structure as the main body of the cage. Its installation structure is complex, the 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 floating type, and the lifting accuracy of the aquaculture cage is uncontrollable. It is easily affected by extreme weather such as typhoons, which causes the main structure of the cage to be deformed by seawater.

[0005] (2) Secondly, modular and standardized product production inevitably leads to smaller individual modules, which puts forward higher requirements for the connecting accessories between the pile legs and the frame system. Existing aquaculture cages have failed to meet the requirements of high modularity and high standardization in terms of connecting accessories.

[0006] (3) Regarding the expansion of aquaculture volume / aquaculture capacity, existing aquaculture cages can only be expanded by increasing the cage volume, but this will result in problems such as insufficient strength. Therefore, the rapid expansion of aquaculture capacity needs further development and research. Summary of the Invention

The modular cage body 3 is controlled by the rack-and-pinion lifting unit, so that the cage body can freely lift along the leg between the water surface and the underwater, realizing functions such as specific water layer aquaculture and typhoon resistance.

[0092] In order to realize the modular and standardized production of aquaculture cages, in this application, one or more assemblies such as legs, cage bodies, and lifting installation units are designed as modular and standardized assemblies. The aquaculture cage has a high degree of assembly generalization, which meets the requirements of rapid installation, high transportability of assemblies, and low transportation cost.

In addition, by designing structures such as the annular mounting ring, the limiting through hole and the marker at the leg connection part, the modular legs can be disassembled, assembled and connected, the legs are recyclable, which facilitates the replacement and maintenance of the legs, and at the same time solves the problem of tooth alignment and connection at the leg connection part.

[0094] This application also provides several types of lifting installation units. Due to the adoption of the modular design concept, the lifting installation units between cage bodies of the same shape are universal, which improves the universality of the assemblies of the modular cage bodies. For the lifting installation units between cage bodies of different shapes, different lifting installation units can be selected according to the shapes of different cage bodies and the assembly structure of the modular cages, so as to meet the installation requirements of cage bodies with various shape designs, improve the applicability of the assemblies of the modular cage bodies, realize modular and standardized mass factory production, ensure manufacturing precision, and facilitate transportation, on-site assembly and cage deployment.

[0095] In addition, the cage body in this application is a cage-shaped space truss structure, which is specifically modularly constructed and expanded by a plurality of cage surface modules.

[0103] As a further preferred solution, each of the lifting installation units in 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, and 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 piece 28; the outer ring panel 24 is arranged 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 side of the inner ring panel 25 forms the inner ring portion 21; a plurality of the horizontal panels 26 are horizontally supported between the outer ring panel 24 and the inner ring panel 25; a plurality of the horizontal panels 26 divide the lifting installation unit into a plurality of hollow chambers; a plurality of the reinforcing plates 27 are arranged upright, and the plurality of reinforcing plates 27 are radially distributed between the outer ring panel 24 and the inner ring panel 25; a plurality of the sliding pieces 28 are evenly distributed on the inner part of the inner ring panel 25, and the contact area between the sliding pieces 28 and the pile leg is smaller than the contact area between the inner ring panel 25 and the pile leg.

[0104] Optionally, the outer ring portion of the second lifting installation unit is further provided with a pin shaft connector 210, as Figure 8 As shown.

[0105] As a further preferred option, such as Figure 14-20 As shown, in this embodiment, the pile leg 1 is a modular pile leg, including at least two pile leg units 12. Each pile leg unit is a hollow tube, and the racks 11 extend outward along the diameter direction on both sides of the hollow tube. Adjacent pile leg units are detachably connected. Each pile leg unit has an annular mounting plate 121 at the connection point. The annular mounting plate is formed by extending radially towards the center from the inner wall of the hollow tube. Each annular mounting plate has multiple limiting through holes 122. The positions of the limiting through holes of the annular mounting plates at the connection point of adjacent pile leg units correspond one-to-one. The two annular mounting plates are stacked on top of each other and are fastened to the limiting through holes by fastening connectors (not shown in the figure) to fix the adjacent pile leg units together. The racks between the adjacent pile leg units extend along the axial direction of the tube.

[0106] The design and manufacture of pile legs need to consider multiple factors, including their strength, stability, corrosion resistance, and maintainability. To address this, this application designs the pile legs for a detachable connection. Specifically, two stacked annular mounting plates are designed on the pile leg unit, with limiting through holes and fastening connectors on the mounting plates. These components work together to lock the two pile leg units in place. When replacing or repairing the pile legs, extensive welding and cutting work is eliminated, improving assembly and disassembly efficiency and reducing maintenance costs.

[0107] However, since this modular pile leg is applied to 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 adjacent pile leg units in order to realize the up-and-down lifting function of the entire gabion body. To solve the above problems, this application also designs multiple position and quantity 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, ensuring the up-and-down lifting function of the gabion body.

[0108] As can be seen, this application designs the legs as modular leg units, which are easy to disassemble and assemble, reducing transportation volume and costs. When leg replacement or repair is needed, extensive welding and cutting work is eliminated, improving assembly and disassembly efficiency and reducing maintenance costs. The height of the legs can be flexibly adjusted according to actual working conditions. The advantage of this technical solution is that it improves the flexibility and convenience of the self-elevating gabion. In addition, it solves the problem of the interlocking teeth of the two leg units, ensuring the vertical lifting function of the gabion body.

[0109] As a further preferred embodiment, each of the annular mounting plates has a central opening 123 in the middle, and each of the pile leg units has a marker near the connection point for positioning the rack direction so that adjacent rack segments can be connected to each other; the marker is one or a combination of two or more of the following: opening, through hole, butt joint, groove, and protrusion.

[0110] This application incorporates a central opening in the annular mounting plate, facilitating timely and rapid observation of the tooth engagement on the pile leg surface during assembly. It also allows for easy adjustment of the alignment of multiple limiting through holes between the two pile legs, enabling rapid assembly and disassembly of the pile legs. In this embodiment, the markers are designed with an open shape, such as... Figure 16-17 As shown, two adjacent pile leg units are provided with two marker openings 124 near the connection point, 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 pile 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 aligned with the same axis. Subsequently, the annular mounting plates at the connection point of the two pile leg units are stacked on top of each other. At this time, the limiting through holes on the two annular mounting plates are aligned with each other. Finally, the two pile leg units are locked together by fastening bolts and other fastening connectors to achieve a fixed connection. In addition, designing the markers as open shapes has an advantage: when the pile legs are installed in the mud, the design of the marker openings 124 helps to improve water tightness and reduce the impact force of water on the pile legs.

[0111] As a further preferred option, the lowest-level pile leg unit is the most important supporting and load-bearing part of the entire gabion. Therefore, this solution incorporates multiple designs to enhance the strength of the pile legs, specifically improving axial and radial support from multiple locations such as the bottom and middle of the pile legs. Specifically: the lowest-level pile leg unit has a mud-entry section 125 at its lower part, and the tube body of the mud-entry section is equipped with several annular reinforcing plates 126 to increase the strength of the tube body; the inner wall of the tube body of the lowest-level pile leg unit is equipped with a reinforcing plate 127, and the reinforcing plate has multiple radially distributed reinforcing ribs 128.

[0112] In this embodiment, multiple annular reinforcing plates are designed inside the tube body of the lowest mud-entry section. Firstly, these plates, evenly distributed on the inner wall of the tube, eliminate or reduce the radial pressure exerted by the silt on the pile leg during installation. Secondly, the annular reinforcing plates have openings in their centers. During the downward pressing of the pile leg, seabed sediment will be pushed into the pile leg to a certain depth, creating negative pressure for fixation. The openings at the bottom of the pile leg are designed to allow silt to enter the pile leg during pressing, increasing the pile leg's grip on the ground. Furthermore, the lowest pile leg unit features a reinforcing plate and radial reinforcing ribs in its center, which enhances the strength of the central part of the pile leg unit, enabling the pile leg to effectively withstand the challenges of the marine environment, such as the impact of ocean currents.

[0113] As a further preferred embodiment, the rack 11 on the lowest-level pile leg unit has two different rack thicknesses: a thick rack 111 and a thin rack 112. The rack thickness on the upper part of the pile leg unit is greater than that on the lower part; the rack thickness on the upper pile leg units is the same as that on the upper rack of the lowest-level pile leg unit. This effectively solves the problem of increasing the upward bearing capacity of the pile leg in the mud, meeting the climbing force requirements of the entire gabion body on the pile leg. On the other hand, the part of the pile leg that enters the mud does not need to bear the upward bearing capacity of the gabion body. Designing it with racks of different thicknesses in different parts helps to reduce the material cost of the pile leg.

[0114] like Figure 21-27 As shown, in this embodiment, the cage surface module includes three types: side module 31, bottom module 32, and top module 33. The side module 31 is located on the side of the modular cage body 3 and forms the side portion of the cage-shaped spatial truss structure. The bottom module 32 is located on the bottom surface of the modular cage body 3 and forms the bottom of the cage-shaped spatial truss structure. The top module is located on the top surface of the modular cage body 3 and forms the top of the cage-shaped spatial truss structure. The three cage surface modules enclose each other to form a cage-shaped spatial truss structure.

[0115] 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 composed of multiple diagonal braces spliced ​​together, and the multiple diagonal braces are connected in a detachable manner. The diagonal brace assembly 313 is a combination of one or more of the following shapes: V-shaped, inverted V-shaped, W-shaped, inverted W-shaped, and X-shaped.

[0116] This embodiment designs multiple crossbeam tubes and diagonal bracing tubes, which are assembled into a surface module in a detachable manner. The standardization of each tube component is high, and each surface module can be assembled, maintained, and repaired independently. The construction time is short, reducing the difficulty of overall assembly and maintenance required for integrally welded cages in the prior art. At the same time, it simplifies maintenance and expansion, and extends the service life of the aquaculture cages.

[0117] As a further preferred embodiment, the diagonal bracing 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 pin shaft connectors 315, and the upper crossbeam 311, the lower crossbeam 312 and the diagonal bracing assembly 313 are provided with pin shaft connectors 315. The aforementioned pin shaft connectors 315 share the same size pin for installation. The upper crossbeam 311, the lower crossbeam 312, the long diagonal brace 3131 and the short diagonal brace 3132 are quickly assembled with each other through pin shaft connectors 315 and pins 316. In this example, the diagonal bracing 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 of one long diagonal brace 3131 via pins and pin connectors 315, forming three X-shaped assemblies. Preferably, the long diagonal braces 3131 are supported on both sides of the side module 31 to improve the strength of the stress point. The pin connectors 315 are standard parts, each including a fixed connection part 3151 and a hanging ear part 3152 connected to the fixed connection part. The pin passes through the hanging ear part 3152.

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

[0119] As a further preferred embodiment, the side module 31 also includes a riser 314 to enhance the connection strength of the side module 31; the riser 314 connects between the upper crossbeam 311 and the lower crossbeam 312 and / or between the diagonal brace assembly 313. This application designs the riser 314, which, according to actual needs, is fixed to the side module in a detachable manner using pins or by welding. The riser 314 prevents the aquaculture cage from deforming, improving the overall structural strength and resistance to wind and waves.

[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 example, the bottom crossbeams 321 are replaced by the lower crossbeams 312 in the side module 31. Each bottom diagonal brace 323 is detachably connected to two adjacent bottom crossbeams 321. The end of the cross tube 322 is detachably connected to the bottom diagonal brace 323. The cross tube 322 is integrally formed or is composed of multiple tubes detachably connected.

[0121] This application designs a bottom module 32 by detachably assembling a bottom crossbeam 321, a cross tube 322, and a bottom diagonal brace 323. The aforementioned tubular components have a high degree of standardization, short construction time, and reduced maintenance difficulty. Furthermore, in this example, the bottom crossbeam 321 of the bottom module 32 can be used in conjunction with the lower crossbeam 312 of the side module 31, or can be replaced by the lower crossbeam 312 in the side module 31. This further reduces the material consumption of the bottom module 32, improves the convenience and reliability of connections between modules, and enhances the strength of the aquaculture cage.

[0122] As a further preferred embodiment, the top 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 aquaculture net cage, and each top diagonal brace 332 is 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] This application designs a top module 33 by detachably assembling a top crossbeam 331, top diagonal brace 332, etc. The aforementioned tubular components have a high degree of standardization, short construction time, and reduced maintenance difficulty. In addition, the top crossbeam 331 of this top module 33 can be used in conjunction 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 material consumption of the top module 33, and further improves the convenience and reliability of the connection between the modules, thereby increasing the strength of the aquaculture cage.

[0124] like Figure 28-31As shown, in the present "mouth"-shaped modular deep-sea aquaculture net cage example, a total of four pile legs are provided, each of the pile legs is equipped with two rack and pinion lifting units 4, which are respectively arranged on the racks on both sides of the pile leg and are in transmission connection with the racks.

[0125] As the modular and standardized production method is more conducive to promoting the industrialization and large-scale development of deep-sea aquaculture net cages, in order to solve the technical problem that the volume of a single module becomes smaller after modular and standardized production and the installation space is limited, the present application improves the installation position and structure of the lifting transmission device, specifically by designing the inner and outer ring portions 22 of the lifting installation unit, which can not only meet the need of maintaining transmission stability for the meshing transmission space of the climbing gear 42, but also meet the installation space requirement of the modular net cage, ensuring the smooth operation and stability of the rack and pinion lifting unit during the entire aquaculture cycle.

[0126] As a further preferred solution, as Figure 31 shown, the mounting base 43 includes a mounting box 431 and connecting lugs 432 disposed 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 accommodating the rack on the pile leg, and the opening 434 is in communication with 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 to mesh with the rack on the pile leg; the connecting lugs 432 are fixedly mounted on the lifting installation unit.

[0127] In addition, the lifting installation unit 2 is provided with a support seat 29 extending from the inner ring portion 21 to the outer ring portion 22, a plurality of crisscross reinforcing ribs are additionally arranged in the support seat 29, and the two connecting lugs 432 are clamped on the support seat 29 and are fixedly connected with the support seat 29. The support seat 29 of the present application is the installation position of the driving device 41 with certain structural reinforcement, which extends from the inner ring portion 21 to the outer ring portion 22 on the lifting installation unit 2. A plurality of crisscross reinforcing ribs are added at this position. The structure of the support seat 29 can not only meet the strength requirement of the lifting installation unit itself, but also meet the bearing capacity and ocean current impact force required during the lifting movement.

[0128] In this example, the mounting base 43 is designed in a box shape, which not only meets the requirement of its own supporting strength, but also meets the requirement of assembly and connection with a plurality of other functional components, specifically including the installation avoidance position for the rack, the installation position for the climbing gear 42, the installation position for the lifting motor, the connecting lugs 432 assembled with the lifting installation node, etc. 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 in transmission connection with the reduction gearbox 413 through the coupling 412, and the climbing gear 42 is fixedly mounted on the transmission shaft of the reduction gearbox 413; the brake 414 is mounted on one side of the lifting motor 411, and is used for emergency stopping of the lifting motor 411. When the lifting motor 411 is suddenly powered off, the brake 414 is triggered to stop the operation of the motor, so as to reduce 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 the present application is internally provided with a pinwheel reducer and a planetary reducer, the pinwheel reducer and the planetary reducer are sequentially arranged at the output end of the lifting motor 411, and the climbing gear 42 is mounted on the transmission shaft of the planetary reducer, so that the entire net cage body can be driven to lift through a wired or wireless control mode, with stable lifting performance.

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