Description

Technical Field

[0001] This utility model relates to the field of marine engineering aquaculture cage technology, and in particular to a large-size truss cage with reinforced bottom strength. Background Technology

[0002] In recent years, nearshore aquaculture in my country has approached saturation, making the promotion of deep-sea cage aquaculture imperative. To achieve modular and standardized production of aquaculture cages, existing modular aquaculture cages (such as patent numbers ZL202410973141.5, ZL202410972984.3, ZL202421728072.3, ZL202421736120.3, ZL202421727018.7, ZL202421727276.5, and ZL202421727298.1) are designed with modular and standardized components, including legs, cage body, and lifting installation units. This results in a high degree of component standardization, fast installation, high transshipment capability, and low transportation costs, effectively meeting the needs of the developing deep-sea aquaculture industry.

[0003] However, due to the complex environment of the open sea, with large waves and frequent typhoons, the safety of cage aquaculture is greatly affected. Therefore, the ability to withstand wind and waves is directly related to the aquaculture effect, and the growth of fish will be greatly affected. The bottom module of the current modular cage is usually formed by connecting several poles to form a mesh structure, such as the cage surface module disclosed in patent number ZL202421736120.3, which is specifically composed of bottom crossbeams, cross tubes, and bottom diagonal braces. The strength of this bottom structure, especially the cross tube in the middle, is weak and can only be used for small-sized cages. For large-sized cages with large spans between the legs, especially those with a span of more than 5 meters, this structure cannot guarantee the strength of the bottom mesh module. It is easy for the structure to loosen or even fall off after being hit by fish, causing the fish to escape en masse and resulting in serious economic losses. Utility Model Content

[0013] The side module includes an upper crossbeam, a lower crossbeam, a diagonal brace assembly, a central reinforcing upright, and a side reinforcing upright. The upper and lower crossbeams are arranged parallel to each other, and the diagonal brace assembly is detachably installed between the upper and lower crossbeams.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This application improves the bottom structure of the net cage by setting up a radially reinforced net frame with a certain thickness in the middle. The ends of the radially reinforced net frame are reinforced and connected to the middle of each bottom crossbeam, thereby improving the rigidity of the bottom module and the side module. This effectively prevents the bottom structure of the net cage from loosening or even falling off due to the collision of fish, causing the fish to escape en masse and thus avoiding economic losses.

[0020] 2. This application improves the bottom strength, especially the central area, by designing the radially reinforced net frame as a double-layered structure with a certain thickness. Simultaneously, it provides a robust installation space for netting, fish-attracting lights, and underwater aeration systems. Preferably, the double-layered net cage base is suitable for installing various types of netting, such as polymer netting, turtle-shell netting, and copper alloy netting. After the installation of netting, fish-attracting lights, underwater aeration systems, and other maintenance components, the entire aquaculture net cage maintenance system operates more smoothly. Even during typhoons, the bright fish-attracting lights encourage fish to gather at the bottom, ensuring the safety of the fish. When the underwater oxygen concentration decreases, the aeration system will activate the aerator based on monitoring values, further ensuring the safety of the fish.

[0021] 3. This application designs the structure and assembly relationship between the radial reinforcement mesh frame and the bottom crossbeam tube. The two are assembled into a bottom module in a detachable manner. Whether it is the assembly of the bottom module or the assembly of the radial reinforcement mesh frame itself, the standardization of each tube component is high. Each bottom module and radial reinforcement mesh frame can be assembled, maintained and repaired independently. The construction time is short, which reduces the difficulty of overall assembly and maintenance of the existing one-piece welded mesh cage. At the same time, it simplifies maintenance and expansion and extends the service life of the aquaculture mesh cage.

[0022] 4. In this application, the main body of the net cage is a cage-shaped spatial truss structure, specifically constructed and expanded modularly from several net cage surface modules. The horizontal cross-sectional shape of the net cage body can be various, such as triangular, square, rectangular, square, quadrilateral, pentagonal, hexagonal, octagonal, etc., or it can be assembled sequentially from multiple individual "square" modular net cages, such as double-square, triple-square, multi-square, etc., or assembled sequentially from multiple individual "square" modular net cages, such as quadrilateral, hexagonal, octagonal, etc., to increase the aquaculture volume, achieve rapid modular expansion of the aquaculture area, and improve the applicability of the aquaculture net cage.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] like Figure 1-9 As shown, a large-scale truss cage 100 with bottom strength reinforcement includes pile legs 1 and modular cage body 2; the modular cage body 2 is a cage-shaped space truss structure, which is constructed from multiple modular cage surface modules, and each of the cage surface modules can be detachably installed on the pile legs 1.

[0040] The cage surface module includes a bottom module 21, which is located on the bottom surface of the modular cage body 2 and is used to form the bottom of the cage-shaped space truss structure. The bottom module 21 includes a bottom crossbeam 211 and a radially reinforcing truss 212. Multiple bottom crossbeams 211 are connected end to end to form the bottom outer frame of the cage. The radially reinforcing truss has a central column 2121, from which several supporting skeletons radiate outward evenly. The ends of each supporting skeleton are detachably connected to the middle of the bottom crossbeam 211. The radially reinforcing truss 212 is a double-layer structure, and the overall thickness of the radially reinforcing truss 212 gradually increases from the periphery to the center.

[0041] This application improves the bottom structure of the net cage by setting a radially reinforced net frame 212 with a certain thickness in the middle. The ends of the radially reinforced net frame 212 are reinforced and connected to the middle of each bottom crossbeam 211, thereby improving the rigidity of the bottom module 21 and the side module 22. This effectively prevents the bottom structure of the net cage from loosening or even falling off due to fish collisions, causing the fish to escape en masse and thus avoiding economic losses.

[0042] As a further preferred embodiment, each support frame includes a horizontal bar 2122 and a diagonal bar 2123. One end of the horizontal bar 2122 and the diagonal bar 2123 overlaps to form an installation point that connects to the middle of the bottom crossbeam 211, and the other end is respectively installed on the outside of the central column 2121. Several short bars 2124 are distributed between the horizontal bar 2122 and the diagonal bar 2123 to form a one-piece frame.

[0043] As a further preferred embodiment, the central column 2121, the crossbar 2122 or / and the diagonal bar 2123 are provided with netting installation components for binding or hooking the netting, or limiting components for installing fish-attracting lights or underwater oxygenation systems.

[0044] This application improves the bottom strength, especially the central area, by designing the radially reinforced net frame 212 as a double-layered structure with a certain thickness. Simultaneously, it provides a robust installation space for netting, fish-attracting lights, and underwater aeration systems. Preferably, the double-layered net cage base is suitable for installing various types of netting, such as polymer netting, turtle-shell netting, and copper alloy netting. After the installation of netting, fish-attracting lights, underwater aeration systems, and other maintenance components, the entire aquaculture net cage maintenance system operates more smoothly. Even during typhoons, the bright fish-attracting lights encourage fish to gather at the bottom, ensuring the safety of the fish. When the underwater oxygen concentration decreases, the aeration system will activate the aerator based on monitoring values, further ensuring the safety of the fish.

[0045] As a further preferred embodiment, both ends of the support frame are provided with quick-connect fittings 24. Each quick-connect fitting 24 shares a pin 25 of the same size for installation. The connection between the support frame and the center column 2121 or the middle of the bottom crossbeam 211 is achieved by quick-connect fittings 24 and pins 25 for detachable and quick assembly. The quick-connect fitting 24 is a standard part, including a first hanging ear 241 and a second hanging ear 242. The pin 25 passes through the first hanging ear 241 and the second hanging ear 242.

[0046] This application designs the structure and assembly relationship between the radially reinforced mesh frame 212 and the bottom crossbeam 211 tube. The two are assembled into a bottom module 21 in a detachable manner. Whether it is the assembly of the bottom module 21 or the assembly of the radially reinforced mesh frame 212 itself, the standardization of each tube component is high. Each bottom module 21 and radially reinforced mesh frame 212 can be assembled, maintained and repaired independently. The construction time is short, which reduces the difficulty of overall assembly and maintenance of the integrally welded mesh cage in the prior art. At the same time, it simplifies maintenance and expansion and extends the service life of the aquaculture mesh cage.

[0047] As a further preferred embodiment, the bottom module 21 also includes a bottom diagonal brace 213. Each bottom diagonal brace 213 has a quick-connect connector 24 at both ends. Each quick-connect connector 24 shares a pin 25 of the same size for installation. The connection between the bottom diagonal brace 213 and the middle of two adjacent bottom crossbeams 211 is detachably and quickly assembled through the quick-connect connector 24 and the pin 25. The quick-connect connector 24 is a standard part, including a first hanging ear 241 and a second hanging ear 242. The pin 25 passes through the first hanging ear 241 and the second hanging ear 242.

[0048] As a further preferred option, the cage body in this application is a cage-shaped spatial truss structure, specifically constructed and expanded modularly from several cage surface modules. The horizontal cross-sectional shape of the cage body is consistent with the shape of the bottom outer frame, and various shapes can be designed, such as triangles, squares, rectangular shapes, grid shapes, quadrilaterals, pentagons, hexagons, octagons, etc., or it can be assembled sequentially from multiple individual "square" modular cages, such as double-square, triple-square, multi-square, etc., or assembled sequentially from multiple individual "rectangular" modular cages, such as quadrilateral, hexagonal, octagonal, etc., to expand and increase the aquaculture volume, realize rapid modular expansion of the aquaculture area, and improve the applicability of the aquaculture cage.

[0049] As a further preferred option, the large-size truss cage also includes a side module 22, which is located on the side of the modular cage body 2 and is used to form the side of the cage-shaped space truss structure.

[0050] The side module 22 includes an upper crossbeam 221, a lower crossbeam 222, a diagonal brace assembly 223, a central reinforcing upright 224, and a side reinforcing upright 225. The upper crossbeam 221 and the lower crossbeam 222 are arranged parallel to each other. The diagonal brace assembly 223 is detachably installed between the upper crossbeam 221 and the lower crossbeam 222. The diagonal brace assembly 223 is composed of multiple diagonal braces spliced ​​together, and the multiple diagonal braces are detachably connected. The diagonal brace assembly 223 is a combination of one or more of the following shapes: V-shaped, inverted V-shaped, W-shaped, inverted W-shaped, and X-shaped. The central reinforcing upright 224 is connected between two adjacent X-shaped assemblies, and the side reinforcing upright 225 is connected between the upper crossbeam 221 and the lower crossbeam 222 or / and between the diagonal brace assembly 223. Preferably, the upper crossbeam 221 and lower crossbeam 222 used in the side module 22 can be shared with the bottom crossbeam 211 and top crossbeam 231 on the bottom module 21 and top module 23, which makes the structure more reasonable and the assembly more convenient.

[0051] This embodiment designs multiple crossbeam tubes and diagonal brace tubes, which are assembled into a side module 22 in a detachable manner. The standardization of each tube component is high, and each side module 22 can be assembled, maintained and repaired independently. The construction time is short, which reduces the difficulty of overall assembly and maintenance of the 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.

[0052] Specifically, in this example, the diagonal bracing assembly 223 includes two long diagonal braces 2231 and four short diagonal braces 2232. Each pair of short diagonal braces 2232 is detachably connected to the middle of a long diagonal brace 2231 via a pin 25 and a quick-connect fitting 24, forming two X-shaped assemblies. Preferably, the long diagonal braces 2231 support both sides of the side module 22 to improve the strength of the stress point. A central reinforcing upright 224 is provided between two adjacent X-shaped assemblies. The two ends of the central reinforcing upright 224 are connected between the upper crossbeam 221 and the lower crossbeam 222 via quick-connect fittings 24. The design of the central reinforcing upright 224, on the one hand, strengthens the strength between the two X-shaped assemblies, thereby improving the strength of the side module 22. On the other hand, it provides support space for the installation of the transversely arranged mesh connecting rod 226 in the middle, improving the installation strength of the mesh connecting rod 226 and preventing the mesh from falling off due to strong wind and waves.

[0053] As a further preferred option, each side module 22 is provided with a horizontally arranged net connecting rod 226 in the middle, and the net connecting rods 226 are connected end to end, with the top net fixed to each net connecting rod 226 to confine the fish within the lower breeding depth of the modular net cage body 2.

[0054] The side module 22 of this application features a horizontally arranged netting connecting rod 226. When a typhoon strikes, the top netting can be tied to the connecting rod 226 inside the netting cage, confining the fish to a certain underwater space. This prevents the fish from being violently battered by large waves and currents caused by the typhoon, thus ensuring their safety and survival rate. Furthermore, adding a horizontal connecting rod to the modular netting cage body 2 further enhances the cage's strength. It also divides the large area of ​​netting on the side module 22 into smaller pieces of the same size, but each side module 22 consists of small pieces of netting of the same specifications. This facilitates rapid initial installation and subsequent maintenance, replacement, and disassembly for damaged netting, while also simplifying modular production and maintenance material preparation.

[0055] Furthermore, the mesh connecting rod 226 is designed to be installed in segments, providing a certain buffer for the installation of the mesh and the mesh frame, thereby improving assembly efficiency.

[0056] As a further preferred option, the large-scale truss cage also includes a top surface module 23, which is located on the top surface of the modular cage body 2 and is used to form the top of the cage-shaped space truss structure.

[0057] The top module 23 includes a top crossbeam 231 and a top diagonal brace 232. Multiple top crossbeams 231 are connected end to end to form a top module with the same shape and size as the top module. Each top diagonal brace 232 has quick-connect connectors 24 at both ends. All quick-connect connectors 24 share a pin 25 of the same size for installation. The connection between the top diagonal brace 232 and the middle of two adjacent top crossbeams is detachably and quickly assembled through the quick-connect connectors 24 and the pin 25. The quick-connect connectors 24 are standard parts, including a first hanging ear 241 and a second hanging ear 242. The pin 25 passes through the first hanging ear 241 and the second hanging ear 242.

[0058] As a further preferred embodiment, the large-scale truss cage 100 with reinforced bottom also includes a lifting and mounting unit 3 and a rack and pinion lifting unit 4. A rack 11 extends axially from the outer side of the pile leg 1. The lifting and mounting unit 3 has an inner ring 31 and an outer ring 32. The lifting and mounting unit 3 is movably fitted onto the pile leg 1 via the inner ring 31. The modular cage body 2 is detachably mounted on the outer ring 32 of the lifting and mounting unit 3. Specifically, the connecting ends of the bottom module 21, side module 22, and top module 23 are all detachably mounted on the outside of the lifting unit via quick-connect fittings 24. The rack and pinion lifting unit 4 is mounted on the lifting and mounting unit 3. The power output end of the rack and pinion lifting unit 4 is equipped with a climbing gear 42. The climbing gear 42 meshes with the rack 11 on the pile leg 1 to drive the modular cage body 2 to move freely up and down along the pile leg 1 on and under the water surface.

[0059] As a further preferred embodiment, at least two rack and pinion lifting units 4 are installed on each of the pile legs 1, and the two rack and pinion lifting units 4 are installed on the same lifting mounting unit 3; each rack and pinion lifting unit 4 includes a drive device 41, the climbing gear 42 is disposed at the power output end of the drive device 41, and the drive device 41 is fixedly installed on the lifting mounting unit 3 by a mounting base.

[0060] This application adopts a modular design concept, designing one or more components such as pile legs 1, cage body 2, and lifting installation unit 3 into modular and standardized components. The lifting installation unit 3 is universal among cage bodies of the same shape, which improves the versatility of the modular cage body 2 components, meets the installation needs of cage bodies with various shapes, improves the applicability of the modular cage body 2 components, realizes modular and standardized mass production in factories, ensures manufacturing accuracy and facilitates transportation, and facilitates on-site assembly and cage deployment.

[0061] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
