Description

Technical Field

[0001] The utility model relates to the technical field of marine aquaculture, in particular to an independently liftable aquaculture net cage which is convenient for towing. Background Art

[0002] The use of aquaculture cages in offshore aquaculture has the characteristics of vast sea areas, resource conservation, excellent water quality conditions, and convenient management. It is an efficient, environmentally friendly, and economical aquaculture method. Offshore aquaculture cages usually need to be towed to a suitable aquaculture sea area by a tugboat for installation. Before towing, the aquaculture cages usually need to be placed on the surface of a buoyant platform made of steel plates, and fasteners are used to connect the aquaculture cages to the buoyant platform. There are also fasteners to connect the aquaculture cages to the buoyancy box to provide buoyancy for the towing of the aquaculture cages at sea. However, since the aquaculture cages need to be connected to the buoyancy box or buoyancy platform before towing, and since the aquaculture cages are large equipment, placing them on the surface of the buoyancy platform also requires larger lifting equipment, and when towing to the designated location, the cages need to be dismantled from the buoyancy box or buoyancy platform, which affects the towing efficiency and cage installation efficiency. The cages need to be connected to the buoyancy box or buoyancy platform by fasteners, and the fasteners are prone to rust after long-term use in the offshore area, so unstable connections are prone to occur. In addition, the existing cages are usually single large cages, and it is impossible to perform separate operations on some of the cultured animals in the cages. Utility Model Content

[0007] The pile legs can be raised and lowered on the first buoyancy frame;

[0008] The first buoyancy frame and the second buoyancy frame are respectively provided with a containing cavity inside, and the containing cavity is used to place the buoyancy body.

[0009] To further illustrate, there are multiple aquaculture cage modules, and the multiple aquaculture cage modules are arranged side by side.

[0010] Further, the aquaculture cage module further includes a first lifting drive mechanism and a second lifting drive mechanism, and the first lifting drive mechanism and the second lifting drive mechanism are respectively arranged on the first buoyancy frame;

[0011] The driving end of the first lifting drive mechanism is in driving connection with the pile leg, and the first lifting drive mechanism drives the pile leg to move up and down relative to the buoyancy truss;

[0012] The driving end of the second lifting drive mechanism is drivingly connected to the cage frame, and the second lifting drive mechanism drives the cage frame to perform up and down lifting movements relative to the buoyancy truss.

[0013] Further, the first buoyancy frame and the second buoyancy frame have the same structure, the first buoyancy frame comprises a plurality of first support rods and a plurality of first connecting rods, the first support rods are arranged in parallel and spaced apart in the horizontal direction and the vertical direction, the first connecting rods are connected between two adjacent first support rods, and the first connecting rods are arranged in pairs to cross each other so that the first buoyancy frame forms a mesh frame structure, and the first support rods and the first connecting rods enclose the accommodating cavity;

[0014] The net box frame includes a plurality of lifting rods, a plurality of second supporting rods and a plurality of second connecting rods, wherein the plurality of lifting rods are arranged in parallel and spaced apart in the vertical direction, and the plurality of second supporting rods are arranged in parallel and spaced apart in the horizontal direction, and the second supporting rods are connected between two adjacent lifting rods, and the second connecting rods are connected between two oppositely arranged second supporting rods, and the second connecting rods are arranged in pairs so that the net box frame forms a mesh frame structure;

[0015] The driving end of the second lifting drive mechanism is transmission-connected to the lifting rod.

[0016] To further illustrate, the horizontal height of the upper end surface of the lifting rod is higher than the horizontal height of the upper end surface of the second supporting rod.

[0022] 2. Since the cage frames can be independently raised and lowered, different cage frames in the aquaculture cage module can be independently controlled to achieve zoned lifting and lowering and separate operation. For example, when only part of the fish needs to be caught, collected, divided, or replaced, a cage frame can be independently controlled to rise above the horizontal plane, while other cage frames are still in the aquaculture stage. In addition, it is also convenient to perform maintenance operations on a cage frame, such as when only the mesh on a cage frame needs to be maintained or replaced, the cage frame can be raised.

[0023] 3. The buoyancy truss can be used as a standing platform, and the operator can stand on the upper surface of the buoyancy truss to operate. The existing cages cannot provide a standing position for the operator. The operator can only lift the mesh to dry for a long enough time, and then drive a small boat to the next door of the cage to set up a ladder for maintenance, or put the mesh back to the dock for cleaning. The independent lifting aquaculture cage can complete these maintenance operations directly at the installation location. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0035] like Figure 1 As shown, an independently liftable aquaculture cage convenient for towing comprises at least one aquaculture cage module 1, wherein the aquaculture cage module 1 comprises a buoyancy truss 2, at least two cage frames 3 and a plurality of pile legs 4, wherein the buoyancy truss 2 comprises a plurality of first buoyancy frames 21 and at least one second buoyancy frame 22, wherein the plurality of first buoyancy frames 21 are connected end to end to enclose a closed structure having an internal space;

[0036] The second buoyancy frame 22 is connected between two oppositely arranged first buoyancy frames 21 to divide the internal space into at least two cage installation spaces 5, and the cage frame 3 can be independently lifted up and down and arranged in the cage installation space 5, and the cage frame 3 is arranged one by one with the cage installation space 5;

[0037] The pile legs 4 can be raised and lowered and arranged on the first buoyancy frame 21;

[0038] The first buoyancy frame 21 and the second buoyancy frame 22 are respectively provided with a receiving cavity 23 therein, and the receiving cavity 23 is used for placing the buoyancy body.

[0039] By setting the buoyancy truss 2, and the pile legs 4 can be set up and down on the first buoyancy frame 21, the net cage frame 3 can be independently set up and down in the corresponding net cage installation space 5, such as Figure 2As shown, in the initial state, the horizontal plane height where the lower end surface of the pile leg 4 is located is higher than or equal to the horizontal plane height where the lower end surface of the buoyancy truss 2 is located, and the horizontal plane height where the lower end surface of the cage frame 3 is located is higher than or equal to the horizontal plane height where the lower end surface of the buoyancy truss 2 is located, so that the buoyancy truss 2 is located at the bottom of the independently liftable aquaculture cage, and because the buoyancy bodies are placed in the accommodating cavities of the first buoyancy frame body 21 and the second buoyancy frame body 22, the buoyancy truss 2 at this time serves as a part of the structure of the independently liftable aquaculture cage, constituting a "buoyancy platform" at the bottom of the independently liftable aquaculture cage.

[0040] When the independently liftable aquaculture cage needs to be towed to a designated location in the sea area, the independently liftable aquaculture cage is slid into the water via a slipway, and a tugboat is used to connect the independently liftable aquaculture cage via a cable to tow the independently liftable aquaculture cage to the designated location. Due to the existence of the buoyancy body, the buoyancy body can provide a buoyancy greater than the dead weight of the independently liftable aquaculture cage, so that the independently liftable aquaculture cage can be directly towed to the designated location conveniently without disassembling the buoyancy box or the buoyancy platform, and the operation is convenient, which effectively improves the towing efficiency and the efficiency of the cage installation at the designated location, and since the buoyancy truss 2 is a part of the structure of the independently liftable aquaculture cage, during the towing process, the independently liftable aquaculture cage relies on the buoyancy truss 2 in its own structure to provide buoyancy, which can effectively ensure the structural stability of the towed object during the towing process, and there will be no problem that the cage and the buoyancy box or the buoyancy platform need to be connected by fasteners, and the cage and the buoyancy box or the buoyancy platform need to be disassembled when towing to the designated location, resulting in an unstable connection and affecting the towing efficiency, and the problem of low cage installation efficiency caused by the need to disassemble the buoyancy box or the buoyancy platform when towing to the designated location is solved.

[0041] After the independently lifting aquaculture cage is towed to the designated position, the pile legs 4 are lowered and inserted into the mud on the seabed. Under the deadweight of the buoyancy truss 2 and the cage frame 3, a certain supporting force is provided for the pile legs 4 after being inserted into the mud, so that the independently lifting aquaculture cage is more firmly fixed at sea. Then, a mesh is installed on the cage frame 3, so that the cage frame 3 forms a breeding space, and fish or other aquacultured objects can be placed for enclosure and breeding. At this time, the cage frame 3 is lowered so that part of the cage frame 3 enters below the horizontal plane. The independently lifting aquaculture cage does not need to be equipped with the mesh in advance, so it does not need wet towing, which avoids the problem of large water resistance caused by the presence of the net during towing, and effectively improves the towing efficiency. Figure 1 As shown, the independent lifting aquaculture cage is in daily use at this time. Preferably, the cage frame 3 can be lowered to the horizontal plane where its upper end surface is located at the middle position of the buoyancy truss 2.

[0042] Further explanation, since the cage frame 3 can be independently raised and lowered, the different cage frames 3 in the aquaculture cage module 1 can be independently controlled to achieve partitioned lifting and individual operation. For example, when only part of the fish needs to be caught, collected, divided, or replaced, a certain cage frame 3 can be independently controlled to rise above the horizontal plane. Figure 3 As shown, at this time, the other net cage frames 3 are still in the breeding stage. In addition, it is also convenient to perform maintenance operations on a certain net cage frame 3, such as when only the mesh on a certain net cage frame 3 needs to be maintained or the net needs to be changed, the net cage frame 3 can be raised.

[0043] To further explain, after completing the entire breeding cycle, if Figure 4 As shown, all the cage frames 3 can be lifted above the horizontal plane, and the cage frames 3 can be maintained for a long period of time. The buoyancy truss 2 can be used as a standing platform, and the operator can stand on the upper surface of the buoyancy truss 2 to operate. The existing cages cannot provide a standing position for the operator, and the operator can only lift the mesh to dry for a long enough time, and then drive a boat to the next door of the cage to set up a ladder for maintenance, or put the mesh back to the dock for cleaning. The independent lifting aquaculture cage can complete these maintenance operations directly at the installation position.

[0044] The independently lifting aquaculture cage is convenient for towing operation, and there is no need to disassemble the buoyancy box or the buoyancy platform, which effectively improves the towing efficiency and the efficiency of the cage installation at the specified position, and can effectively ensure the structural stability of the towed object during the towing process. The cage frame 3 can be independently lifted and lowered, which is convenient for operation and maintenance operations, and solves the existing problems of unstable connection, low towing efficiency, low cage installation efficiency caused by the need to disassemble the buoyancy box or the buoyancy platform for cage towing, as well as the technical problem of being unable to perform separate operations on a certain part of the aquaculture in the cage.

[0045] like Figure 5 As shown, in another embodiment of the present utility model, the number of the aquaculture cage modules 1 is multiple, and the multiple aquaculture cage modules 1 are arranged side by side.

[0046] By setting a plurality of the aquaculture cage modules 1 and arranging the plurality of the aquaculture cage modules 1 side by side, the plurality of the aquaculture cage modules 1 form a whole of the independently liftable aquaculture cage, so that the typhoon disaster resistance of the independently liftable aquaculture cage is greatly enhanced, and the effect of high-density aquaculture can be achieved, and centralized management is convenient. The cage frame 3 in each of the aquaculture cage modules can be lifted and lowered separately, which can facilitate the independent processing of aquatic products in each cage frame 3 (such as collecting fish, lifting fish and separating fish), and facilitate the maintenance of a single cage frame 3.

[0047] Specifically, two net cage frames 3 are provided, and one second buoyancy frame 22 is provided;

[0048] The second buoyancy frame 22 is arranged in the middle of the closed structure enclosed by the first buoyancy frame 21 to divide the internal space into two cage installation spaces 5 symmetrically arranged relative to the second buoyancy frame 22, and the two cage frames 3 are respectively arranged in the corresponding cage installation spaces 5.

[0049] Specifically, three aquaculture cage modules 1 are provided, and each cage frame 3 can enclose a closed aquaculture space of 10,000 cubic meters of water after the mesh is installed. When three aquaculture cage modules 1 are provided, and two cage frames 3 are provided in each aquaculture cage module 1, there are a total of 60,000 cubic meters of water aquaculture space in the independently lifting aquaculture cage, of which 6 aquaculture spaces of 10,000 cubic meters of water can realize independent lifting partition operation, effectively realizing the independent lifting of small water bodies, and there is no need to operate the aquaculture spaces of 60,000 cubic meters of water at the same time, and only needs to operate different aquaculture spaces independently according to needs.

[0050] Further, the aquaculture cage module 1 further comprises a first lifting drive mechanism and a second lifting drive mechanism, wherein the first lifting drive mechanism and the second lifting drive mechanism are respectively arranged on the first buoyancy frame 21;

[0051] The driving end of the first lifting drive mechanism is in transmission connection with the pile leg 4, and the first lifting drive mechanism drives the pile leg 4 to move up and down relative to the buoyancy truss 2;

[0052] The driving end of the second lifting drive mechanism is in driving connection with the net cage frame 3 , and the second lifting drive mechanism drives the net cage frame 3 to perform up and down lifting movements relative to the buoyancy truss 2 .

[0053] By setting the first lifting drive mechanism and the second lifting drive mechanism, it is possible to drive the pile legs 4 to move up and down relative to the buoyancy truss 2, and to drive the cage frame 3 to move up and down relative to the buoyancy truss 2, thereby facilitating the control of the lifting position of the pile legs 4 and the lifting position of the cage frame 3.

[0054] like Figure 6 and Figure 7As shown, it is further explained that the structures of the first buoyancy frame 21 and the second buoyancy frame 22 are the same, the first buoyancy frame 21 includes a plurality of first support rods 211 and a plurality of first connecting rods 212, the first support rods 211 are arranged in parallel and spaced apart in the horizontal direction and the vertical direction, the first connecting rods 212 are connected between two adjacent first support rods 211, and the first connecting rods 212 are arranged crosswise in pairs to form a mesh frame structure of the first buoyancy frame 21, the first support rods 211 and the first connecting rods 212 enclose the accommodating cavity 23; by arranging the first support rods 211 and the first connecting rods 212, the first support rods 211 can provide horizontal supporting force, the first connecting rods 212 can provide reinforcement for the first buoyancy frame 21 and the second buoyancy frame 22, and the first support rods 211 and the first connecting rods 212 enclose the accommodating cavity 23 to place the buoyancy body.

[0055] The cage frame 3 includes a plurality of lifting rods 31, a plurality of second support rods 32 and a plurality of second connecting rods 33. The plurality of lifting rods 31 are arranged in parallel and spaced apart in the vertical direction, and the plurality of second support rods 32 are arranged in parallel and spaced apart in the horizontal direction. The second support rods 32 are connected between two adjacent lifting rods 31, and the second connecting rods 33 are connected between two oppositely arranged second support rods 32. The second connecting rods 33 are arranged crosswise in pairs to form a mesh frame structure of the cage frame 3. By arranging the second support rods 32 and the second connecting rods 33, a supporting function of the cage frame 3 can be provided, and a mesh can be installed, so that the cage frame 3 is enclosed to form a breeding space after the mesh is installed.

[0056] The driving end of the second lifting drive mechanism is in transmission connection with the lifting rod 31. The lifting rod 31 can be connected with the second lifting drive mechanism to realize the lifting of the net cage frame 3 and the position fixing of the net cage frame 3 after lifting.

[0057] Specifically, four first support rods 211 are provided, and the four first support rods 211 are arranged in parallel and spaced apart to form a rectangular shape. Between two adjacent first support rods 211, a plurality of first connecting rods 212 are arranged and arranged along the length direction of the first support rods 211, so that the first buoyancy frame 21 and the second buoyancy frame 22 form a mesh frame structure. The first buoyancy frame 21 can also be obtained by splicing multiple sections, and multiple sections of the mesh frame structure can be first made, and the multiple sections of the mesh frame structure can be assembled at the assembly site when transported to the slipway. Since the overall volume of the buoyancy truss 2 is very large, it is transported and installed in multiple sections of modules, which can facilitate transportation and save transportation costs, and modular assembly can effectively improve assembly efficiency and save assembly time.

[0058] Specifically, longitudinal racks can be respectively arranged on both symmetrical sides of the pile legs 4, and longitudinal racks can be respectively arranged on both symmetrical sides of the lifting rod 21. The first lifting drive mechanism and the second lifting drive mechanism have the same structure. The first lifting drive mechanism adopts a structure in which a motor is connected to a reduction gear box to drive a gear to rotate. The gear is meshed with the corresponding rack on the pile leg 4, or the gear is meshed with the corresponding rack on the lifting rod 31. When the gear rotates, it drives the pile leg 4 to move up and down, and the gear rotation drives the lifting rod 31 to move up and down.

[0059] Specifically, six legs 4 are provided, and one leg 4 is provided at each corner of the closed structure formed by the first buoyancy frame 21, and the second buoyancy frame 22 is provided with the legs 4 at the position corresponding to the first buoyancy frame 21. By also providing the legs 4 at the position of the second buoyancy frame 22 corresponding to the first buoyancy frame 21, the support stability of the buoyancy truss 2 can be improved, thereby improving the installation stability of the independent lifting aquaculture cage in the sea, and effectively improving the ability to resist typhoon disasters.

[0060] To further explain, the second lifting drive mechanism located in the middle (ie, corresponding to the second buoyancy frame 22 ) may also be arranged on the surface of the second buoyancy frame 22 .

[0061] Specifically, the horizontal height of the upper end surface of the lifting rod 31 is higher than the horizontal height of the upper end surface of the second support rod 32. The length of the lifting rod 31 protrudes from the upper end surface of the second support rod 32. When the mesh needs to be lowered below the water surface, the lifting rod 31 can provide a larger descending distance, so that the second support rod 32 can be lowered to a certain depth below the water surface. For example, when a typhoon comes, the second support rod 32 can be lowered to a certain depth below the horizontal plane (for example, 8 meters below the water surface), so that the breeding space surrounded by the mesh is completely lowered below the horizontal plane, and at the same time, the buoyancy truss 2 is raised a certain distance relative to the pile legs 4 (because the pile legs 4 are already inserted in the mud at this time, the height of the pile legs 4 will not change, but the position of the buoyancy truss 2 relative to the pile legs 4 will change). At this time, the entire buoyancy truss 2 is completely above the horizontal plane. With the weight of the buoyancy truss 2 and the cooperation of the pile legs 4, the overall stability of the independently lifting breeding cage in typhoon resistance can be improved. Moreover, because the breeding space surrounded by the mesh is already at a certain depth below the water surface at this time, this depth can provide a relatively calm breeding environment, so that the independently lifting breeding cage can have better typhoon resistance.

[0062] Preferably, the plurality of legs 4 are respectively arranged at corners of the closed structure enclosed by the first buoyancy frame 21 .

[0063] By arranging the pile legs 4 at the corners of the closed structure enclosed by the first buoyancy frame 21, the pile legs 4 can provide strong support to the four corners of the buoyancy truss 2, thereby ensuring the support stability of the overall structure by the pile legs 4.

[0064] Preferably, the buoyancy truss 2 also includes a plurality of pile seats 24, and the pile seats 24 are provided at the corners of the closed structure enclosed by the first buoyancy frame body 21. The pile seats 24 are penetrated by through holes in the up and down directions, and the pile legs 4 pass through the through holes and are slidably connected to the pile seats 24.

[0065] By providing the pile fixing seat 24, a more stable limiting effect can be provided for the pile legs 4 located at the corners, thereby preventing the pile legs 4 from swinging left and right, and further improving the supporting stability of the pile legs 4 on the overall structure.

[0066] To further explain, the buoyancy body is a foam block or an air bag.

[0067] The buoyancy body may be a foam block or an air bag, so as to provide the aquaculture cage module with a buoyancy greater than its own, so that when the independently liftable aquaculture cage is towed, the independently liftable aquaculture cage can float on the sea surface, facilitating towing.

[0068] A method for using an independently liftable aquaculture cage that is convenient for towing, wherein the method comprises at least one of the following steps:

[0069] The independent lifting aquaculture cage is towed to a designated location: Figure 2 As shown, in the initial state, the horizontal plane height where the lower end surface of the pile leg 4 is located is higher than or equal to the horizontal plane height where the lower end surface of the buoyancy truss 2 is located, and the horizontal plane height where the lower end surface of the cage frame 3 is located is higher than or equal to the horizontal plane height where the lower end surface of the buoyancy truss 2 is located, so that the buoyancy truss 2 is located at the bottom of the independent lifting aquaculture cage, and the independent lifting aquaculture cage is towed to a designated position;

[0070] Installation of the independent lifting aquaculture cage at a designated location: After the independent lifting aquaculture cage is towed to the designated location, Figure 1 As shown, the pile legs 4 are lowered and fixed (specifically, the pile legs 4 are lowered and inserted into the mud fixed on the seabed), a mesh is installed on the cage frame 3, and the cage frame 3 is lowered so that part of the cage frame 3 enters below the horizontal plane;

[0071] The independent lifting of the cage frame 3 in the independent lifting aquaculture cage: Figure 3 As shown, the cage frame 3 is raised above the horizontal plane, and independent operation and maintenance operations are performed on each cage frame 3. The operation operations may be catching fish, collecting fish, sorting fish and changing fish, and the maintenance operations may be maintaining the mesh or maintaining the cage frame 3.

[0072] The method for using the independently liftable aquaculture cage that is convenient for towing is easy to operate, can realize the independent lifting operation of the aquaculture cage, and is convenient for maintenance.

[0073] Further, the method for using the independently liftable aquaculture cage that is convenient for towing further includes the following steps:

[0074] like Figure 8 As shown, the second support rod 32 is lowered below the horizontal plane, and the buoyancy truss 2 is raised relative to the pile legs 4, so that the entire buoyancy truss 2 is completely located above the horizontal plane;

[0075] Alternatively, the buoyancy body is removed, and the buoyancy truss 2 and the cage frame 3 are lowered relative to the pile legs 4, so that the entirety of the buoyancy truss 2 and the cage frame 3 are completely located below the horizontal plane.

[0076] When a typhoon disaster occurs, the buoyancy truss will be greatly impacted, and the water surface may submerge the upper surface of the breeding space surrounded by the mesh. At this time, the second support rod can be lowered below the horizontal plane, and the buoyancy truss can be raised relative to the pile legs so that the entire buoyancy truss is completely above the horizontal plane. With the weight of the buoyancy truss and the cooperation of the pile legs, the overall stability of the independently liftable breeding cage in typhoon resistance can be improved. At this time, since the breeding space surrounded by the mesh is already at a certain depth below the water surface, this depth can provide a relatively calm breeding environment, so that the independently liftable breeding cage can have better typhoon resistance.

[0077] Alternatively, the buoyancy body can be removed, for example, the air in the airbag can be released, and then the buoyancy truss and the cage frame can be lowered relative to the pile legs so that the buoyancy truss and the cage frame as a whole are completely below the horizontal plane (for example, 8 meters below the water surface). At this time, the buoyancy body will not affect the stability of the buoyancy truss below the horizontal plane, and because the breeding space surrounded by the mesh and the buoyancy truss are already at a certain depth below the water surface, this depth can provide a relatively calm breeding environment, so that the independently lifting breeding cage can have better typhoon resistance.

[0078] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
