Description

Technical Field

[0001] The utility model belongs to the technical field of marine ecological aquaculture, and particularly relates to a modular combined cage framework and a marine ecological aquaculture cage system. Background Art

[0002] Cages are essential facilities for marine ecological aquaculture. Different from calm pond aquaculture, the marine aquaculture environment has strong winds and waves. Therefore, steel structure cages are usually adopted. The specific structure is to use various specifications of steel sections for welding. After welding, a cage framework with multiple independent aquaculture units as a whole is formed. Then, floats are installed on the cage framework to generate buoyancy. The disadvantage of this steel structure cage is that it is huge, heavy and difficult to transfer. Therefore, the whole service life cycle of this kind of cage usually only has the first launch and the final salvage. It cannot be reused in different areas. Moreover, when one or some of the aquaculture units need to be cleaned or damaged, the whole cage needs to be lifted. This not only has poor flexibility in use and requires a lot of operators, but also affects other aquaculture units and is not conducive to the healthy growth of aquatic organisms. Therefore, it is difficult to be applied in small-scale marine pastures and fishermen groups. Content of the Utility Model

Detailed Embodiment

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application 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 should not be construed as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or several of such features. In the description of the present application, the meaning of "a plurality of" and "several" is two or more, unless otherwise specifically defined.

[0026] Please refer to Figures 1 to 7 , and now the modular combined net cage framework provided by the present utility model will be described. The modular combined net cage framework includes a plurality of single cage modules 10 and a plurality of side cage modules 20 assembled into one body; each single cage module 10 is distributed in a rectangular array to form a framework main body, and each single cage module 10 is respectively used to connect a netting to enclose its own independent aquaculture space; each side cage module 20 is respectively connected to each side of the framework main body and is used to install a float assembly; wherein, adjacent single cage modules 10, adjacent side cage modules 20, and between a side cage module 20 and its adjacent single cage module 10 are detachably connected through a quick plug structure 30.

[0027] It should be noted that in this embodiment, both the single cage module 10 and the side cage module 20 are formed by welding or detachably connecting metal section steels such as rectangular tubes. Considering the transportation convenience of fishermen users, the single cage module 10 and the side cage module 20 can be a screwed assembly structure of rectangular tubes, so that the rectangular tubes can be used as transportation units for transfer. After arriving at the target area, first assemble the single cage module 10 and the side cage module 20 from the rectangular tubes, and then connect the single cage module 10 and the side cage module 20 through the quick plug structure 30. Similarly, at the end of the aquaculture cycle or when it is necessary to change the aquaculture area, each quick plug structure 30 can be removed to form independent single cage modules 10 and side cage modules 20, and then transferred to the target area. During the transfer process, the single cage module 10 and the side cage module 20 can be further disassembled into rectangular tubes, or can be directly transferred without disassembly, which is flexible in use, convenient for transfer and saves labor.

[0028] In this embodiment, each single-box module 10 is distributed in a rectangular array to form a rectangular or square skeleton body. Then, each side-box module 20 is sequentially installed along the four sides of the skeleton body. Finally, a float assembly such as a buoy or an airbag is installed on each side-box module 20, thereby forming an integral structure that provides buoyancy all around and has high stability.

[0029] Compared with the prior art, the modular combined net cage skeleton provided in this embodiment uses a plurality of independent single-box modules 10 and side-box modules 20 connected together through a quick-insert structure 30, which is convenient for flexible assembly and disassembly and saves labor, thus meeting the need for repeated use in different areas. Underwater, any one or more single-box modules 10 can be removed to clean and repair the netting, thereby avoiding affecting the aquatic organisms in the breeding space enclosed by other single-box modules 10. It is particularly suitable for popularization and application in small-scale marine pastures and among fishermen groups.

[0030] In some embodiments, referring to Figures 2 to 6 , card slots 100 are provided at each corner position of the single-box module 10 and the side-box module 20. The card slots 100 of adjacent single-box modules 10 that are close to each other, the card slots 100 of adjacent side-box modules 20 that are close to each other, and the card slots 100 of adjacent side-box modules 20 and single-box modules 10 that are close to each other together form a mortise and tenon groove / hole 31 / 32. A mortise and tenon pin 33 is inserted into the mortise and tenon groove / hole 31 / 32 to form the quick-insert structure 30.

[0031] It should be noted that the above single-box module 10 is a square box body, and the side-box module 20 is a cuboid box body, and the length of the side-box module 20 is equal to the side length of the single-box module 10. Thus, the four card slots 100 at the four corners of the four single-box modules 10 in the middle can enclose a mortise and tenon hole 32 after the four corners are opposite to each other. Since there are only three card slots 100 opposite to each other between the single-box module 10 at the corner position of the skeleton body and the two adjacent side-box modules 20 on its two adjacent sides, the card slots 100 of the single-box module 10 at this position and the card slots 100 of the two side-box modules 20 together enclose a mortise and tenon groove 31. However, whether it is the mortise and tenon hole 32 or the mortise and tenon groove 31, it can cooperate with the inserted mortise and tenon pin 33 to achieve reliable connection of adjacent modules. When it is necessary to remove one of the single-box modules 10, only the mortise and tenon pins 33 at the four corner positions of this single-box module 10 need to be pulled out.

[0032] To ensure the connection strength, in this embodiment, high-strength steel or additional high-strength steel patch plates are used at each corner position of the single-box module 10 and the side-box module 20, thereby ensuring the structural strength of each card slot 100. At the same time, the mortise and tenon pin 33 is made of high-strength steel. To improve the anti-corrosion performance and avoid corrosion adhesion between the mortise and tenon pin 33 and the mortise and tenon hole 32 or the mortise and tenon groove 31, resulting in difficult disassembly, each card slot 100 and the mortise and tenon pin 33 can be subjected to anti-corrosion plating treatment.

[0033] As a specific structure of the above card slot 100, please refer to Figure 4 and Figure 5 , the card slot 100 includes an inner arc portion 101 and an outward expansion portion 102. The central angle of the inner arc portion 101 is greater than 90 degrees. The outward expansion portion 102 is connected to the mouth of the inner arc portion 101 to form a flared shape. Since the central angle of the inner arc portion 101 is greater than 90 degrees, the size of the mouth formed at the connection position between the inner arc portion 101 and the outward expansion portion 102 is smaller than the diameter of the inner arc portion 101. In this way, it can be restricted that the part of the mortise and tenon pin 33 inserted into the inner arc portion 101 slips off from the outward expansion portion 102. On this basis, forming a flared structure by connecting the outward expansion portion 102 to the mouth of the inner arc portion 101 can not only increase the cross-sectional size of the mortise and tenon pin 33, thereby improving the structural strength of the mortise and tenon pin 33, but also make the part where the mortise and tenon pin 33 cooperates with each card slot 100 form a smooth gradient structure by using the outward expansion portion 102, so as to avoid the mortise and tenon pin 33 from breaking due to excessive stress concentration, and further ensure the connection reliability.

[0034] It should be noted that, as Figure 5 shown, a limiting groove 103 is provided on the side wall of the inner arc portion 101, and an opening ring 34 is clamped in the limiting groove 103, and the opening ring 34 abuts against the end face of the mortise and tenon pin 33. After the mortise and tenon pin 33 is inserted into the mortise hole 32 or the mortise groove 31, the opening ring 34 clamped in the limiting groove 103 forms an axial limit on the mortise and tenon pin 33, so as to avoid the mortise and tenon pin 33 from slipping off and causing the connection to fail. When disassembly is required, only the opening ring 34 needs to be removed and then the mortise and tenon pin 33 can be pulled out, and the operation is simple and labor-saving.

[0035] To further facilitate disassembly, please refer to Figure 4 , a connection hole 331 is provided at the center of the above mortise and tenon pin 33, and the connection hole 331 is used to connect a pin puller. After screwing the pin puller into the connection hole 331, the mortise and tenon pin 33 is pulled outwards by sliding the inertia block of the pin puller. Of course, in order to avoid corrosion of the connection hole 331 caused by long-term immersion in seawater, a waterproof cover can be installed on the end face of the mortise and tenon pin 33 to cover the mouth of the connection hole 331.

[0036] In some possible implementation manners, please refer to Figure 1 , both the single-box module 10 and the side-box module 20 are connected into a cuboid frame by twelve side beams 11 and eight corner joints 12; wherein, the corner joint 12 includes three connecting heads 121 that are perpendicular to each other in pairs, and a quick-insert structure 30 is provided on the corner joint 12, and each connecting head 121 is hermetically inserted and fixed to the end of the corresponding side beam 11.

[0037] The difference between the single - box module 10 and the side - box module 20 is that the short side of the side - box module 20 uses a shorter side beam 11, and the long side and the high side are the same as those of the single - box module 10. Therefore, only two lengths of side beams 11 need to be configured, which can improve the interchangeability of the side beams 11, thereby enhancing the assembly flexibility and convenience. On this basis, since the side beam 11 is a rectangular tube or a square tube, the connection head 121 is inserted and fixed to the side beam 11. Specifically, the connection head 121 is inserted into the inner hole of the side beam 11, and a gasket 133 can be clamped between the end face or the inner hole of the connection head 121 and the side beam 11 to ensure the connection tightness, prevent seawater from entering the side beam 11 and increasing the self - weight, and avoid internal corrosion of the side beam 11 and affecting its service life.

[0038] Specifically, please refer to Figure 6 , in this embodiment, the side beam 11 is a rectangular tube beam suitable for the insertion of the connection head 121, and at least one first perforation 111 is distributed at intervals at both ends of the side beam 11. At least one second perforation 1211 corresponding to the first perforation 111 is provided on each connection head 121. A fastener 13 is inserted through the corresponding first perforation 111 and second perforation 1211 together. After the connection head 121 is inserted into the side beam 11, it is connected by the fastener 13, thereby preventing the connection head 121 from slipping off the side beam 11 and improving the connection stability.

[0039] Optionally, the structure of the fastener 13 in this embodiment is as shown in Figure 7 . The fastener 13 includes a stud 131 and a nut sleeve 132. One end of the nut sleeve 132 is closed and provided with a limit card 1321, and the other end passes through the connection head 121. One end of the stud 131 passes through the connection head 121 and is threadedly connected to the nut sleeve 132. Wherein, gaskets 133 that are hermetically abutted against the side wall of the side beam 11 are sleeved on both the stud 131 and the nut sleeve 132. The ends of the stud 131 and the nut sleeve 132 that pass through the inside of the connection head 121 are screwed and fixed to each other. At the same time, the exposed ends of the stud 131 and the nut sleeve 132 ensure the sealing of the first perforation 111 through the gasket 133, preventing seawater from entering the inside of the connection head 121. Thus, it can prevent the connection ends of the stud 131 and the nut sleeve 132 from contacting seawater and rusting, ensuring that the stud 131 and the nut sleeve 132 can be smoothly disassembled when disassembling the single - box module 10 and the side - box module 20.

[0040] It should be understood that referring to Figure 6 and Figure 7, in this embodiment, grooves 112 are provided at the side wall of the side beam 11 corresponding to each of the first through holes 111. The limiting clamping plate 1321 is embedded in the groove 112 and forms a clamping fit with the groove 112 along the circumferential direction of the first through hole 111. In order to prevent the exposed end of the screw sleeve 132 from protruding from the side wall of the side beam 11 and affecting the connection stability between adjacent modules, a groove 112 that can accommodate the limiting clamping plate 1321 is formed in the side wall of the side beam 11. Thereby, the side walls of the side beams 11 of adjacent modules can be closely attached, thus improving the connection stability. On this basis, the boundaries of the limiting clamping plate 1321 and the groove 112 match and are non-circular, so that the rotational freedom of the screw sleeve 132 can be restricted after the limiting clamping plate 1321 is embedded in the groove 112. When disassembling the fastener 13 and screwing the stud 131, the screw sleeve 132 can be prevented from rotating, thus facilitating the disassembly operation of the fastener 13.

[0041] Based on the same inventive concept, in combination with Figures 1 to 7 it is understood that an embodiment of the present application further provides a marine ecological aquaculture cage system, including the above modular combined cage framework.

[0042] Compared with the prior art, the marine ecological aquaculture cage system provided by the present utility model adopts the above modular combined cage framework, and a plurality of independent single-cage modules 10 and side-cage modules 20 are connected into one body through a quick-insert structure 30, which is convenient for assembly and disassembly and saves labor, thus meeting the requirement of repeated use in different areas. Underwater, any one or more of the single-cage modules 10 can be removed to clean and repair the netting, thereby avoiding affecting the aquatic organisms in the aquaculture space enclosed by other single-cage modules 10. It is particularly suitable for popularization and application in small-scale marine ranches and fisherman groups.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
