Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, and in particular to a netting replacement device for deep-sea cages. Background Technology

[0002] Deep-sea cages are large-scale aquaculture facilities set up in open coastal waters at depths of 15 meters or more. They have significant advantages such as strong resistance to wind and waves, large aquaculture capacity, fast fish growth, and good product quality. Their specific structure includes a frame and netting fixed to the outside of the frame.

[0003] A netting replacement device allows for the disassembly and replacement of the netting. For example, Chinese Patent Publication No. CN118177122A discloses a netting replacement device for laid-out gabions, including: a cylindrical gabion, a new netting laying bracket, an old netting recovery bracket, and a central rotating shaft. The new netting laying bracket and the old netting recovery bracket are connected to the cylindrical gabion via the central rotating shaft and rotate around the cylindrical gabion. During rotation, the old netting of the cylindrical gabion can be replaced simultaneously. The old netting recovery bracket rotates first to recover the old netting, and the new netting laying bracket follows behind to lay the new netting. This invention uses the cooperation of two brackets to complete the overall replacement of the gabion, achieving integrated and mechanized netting replacement.

[0004] In practice, the replacement of the netting requires the cooperation of motors and gears. The motors and other equipment operate at sea for a long time, which can easily lead to rust problems, making it inconvenient to maintain the replacement device and affecting the efficiency of netting replacement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing replacement devices, such as inconvenience in maintenance and high maintenance costs, by proposing a replacement device for deep-sea cage netting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a deep-sea cage netting replacement device, including a net frame, the net frame consisting of a support column and at least two support frames, the support frames having a ring structure, the support column being fixedly connected to the midpoint of the two support frames, and a pair of support members being provided around the support column, the pair of support members rotating along half a circumference of the support frame to lay and fold the netting;

[0008] The pair of support members are fixed together by a limiting structure, and the support members and the mesh are detachably connected by an elastic structure.

[0009] Furthermore, the support member has a U-shaped cross-section, with its two arms bent outward to form a bent portion. A pair of support members are arranged opposite each other, and the bent portions on both sides are arranged in a V-shape. The two arms of the support member are rotatably connected to the two ends of the support column, respectively.

[0010] Furthermore, each of the pair of support members is provided with a receiving groove on the opposite side, and a docking part and a docking groove are provided on the opposite side respectively. The pair of support members abut against each other so that the docking part is engaged in the docking groove.

[0011] Furthermore, the limiting structure includes limiting members, and a pair of the supporting members are provided with limiting grooves on the sides. The limiting members are U-shaped and are fixedly connected to the limiting grooves on both sides by fasteners.

[0012] Furthermore, the elastic structure includes an elastomer, and the mesh is stretched to cover the periphery and bottom of the support frame, and several elastomers are evenly distributed at both ends of the mesh. The ends of the elastomers extend outward at an angle to form a pair of protruding structures.

[0013] Furthermore, the receiving groove connects the two sides of the support member to form a slot, the elastic body is inserted into the receiving groove, and the protruding structures on both sides are engaged in the slot through abutment deformation.

[0014] The present invention provides a netting replacement device for deep-sea cages, which has the following advantages: The present invention has a pair of support members rotatably connected to the support column. When one side of the pair of support members abuts against each other, they are fixed together by limiting members to prevent the support members from rotating freely and causing gaps between the two ends of the netting. When the other side of the pair of support members abuts against each other, the pair of support members, together with the bent parts on both sides, form a receiving space, which can then be used to fold and store the netting. In addition, after long-term use, the netting and support members can be separated by unlocking the elastic body, so that the netting can be washed or replaced. The structure is simple and highly practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A deep-sea cage netting replacement device includes a net frame 1, which is composed of a support column 11 and at least two support frames 12. The support frames 12 are in a ring structure. The support column 11 is fixedly connected to the midpoint of the two support frames 12. A pair of support members 2 are provided around the support column 11. The pair of support members 2 rotates along half a circumference of the support frame 12 to lay and fold the netting 3.

[0024] The pair of support members 2 are fixed together by a limiting structure 4, and the support member 2 and the mesh 3 are detachably connected by an elastic structure 5.

[0025] Furthermore, the support member 2 has a U-shaped cross-section, with its two arms bent outward to form a bent portion 21. A pair of support members 2 are arranged opposite each other, and the bent portions 21 on both sides are arranged in a V-shape. The two arms of the support member 2 are rotatably connected to the two ends of the support column 11.

[0026] In this embodiment, as Figure 1 , 4 As shown, a pair of support members 2 are brought together by a relative half-circle rotation, and at this time the netting 3 is laid on the outside of the net frame 1. The net frame 1 and the two support members 2 can support the netting 3 on the one hand, and on the other hand, the support makes the netting 3 and the net frame 1 form a cylindrical structure with an opening.

[0027] Furthermore, by engaging the docking part 23 with the docking groove 24, seafood is prevented from being exposed along the gap. Further still, after the pair of support members 2 rotate in opposite directions to store the netting 3, the bending part 21 makes the pair of support members 2 parallel and creates a space between them. The netting 3 is stored in the space, which facilitates the cleaning of impurities or replacement of the netting 3 and the net frame 1.

[0028] Specifically, the mesh garment 3 can be divided into an outer part and a bottom part. The bottom of the outer part and the bottom part can be fixed together by sewing or other means, so that the outer part of the mesh garment 3 is closed and the top part forms an opening.

[0029] Furthermore, each of the pair of support members 2 is provided with a receiving groove 22 on the opposite side, and a docking part 23 and a docking groove 24 are provided on the opposite side respectively. The pair of support members 2 abut against each other so that the docking part 23 is engaged in the docking groove 24.

[0030] More specifically, the limiting structure 4 includes a limiting member 41, and a pair of the supporting members 2 are provided with limiting grooves 42 on the side. The limiting member 41 has a U-shaped structure and is fixedly connected to the limiting grooves 42 on both sides by fasteners.

[0031] In this embodiment, the fastener is preferably a stainless steel locking bolt. The locking bolt passes through the limiting member 41 and is threadedly connected to the support member 2. The limiting member 41 engages with the limiting groove 42 to prevent the pair of support members 2 from swinging randomly after they are parallel.

[0032] Specifically, after the mesh 3 is stored, the spacing between the pair of support members 2 is increased due to the setting of the bending part 21. Therefore, limiting grooves 42 can be set on both sides of the support member 2, and the pair of support members 2 can be fixed by limiting members 41 of two different specifications.

[0033] In general, the elastic structure 5 includes an elastic body 51. The mesh 3 is stretched to cover the periphery and bottom of the support frame 12, and several elastic bodies 51 are evenly distributed at both ends of the mesh 3. The ends of the elastic bodies 51 extend outwards to form a pair of protruding structures 52.

[0034] Finally, the receiving groove 22 connects the two sides of the support member 2 to form a slot 25, the elastic body 51 is inserted into the receiving groove 22, and the protruding structures 52 on both sides are engaged in the slot 25 by abutting deformation.

[0035] In this embodiment, a reinforcing strip is fixedly connected to the outer edge of the mesh 3, and an elastic body 51 is fixedly connected to the periphery of the reinforcing strip. The elastic body 51 and the protruding structure 52 are integrally formed and are preferably made of materials with deformation capabilities such as rubber and plastic.

[0036] In specific operation, the elastic body 51 and the two protruding structures 52 form a triangular structure. The elastic body 51 is inserted into the receiving groove 22 through the two guide slopes, while the two protruding structures 52 are engaged in the slot 25 through abutment deformation. The two ends of the mesh 3 can be connected and fixed to a pair of support members 2.

[0037] Specifically, the reinforcing strip is inserted into the receiving groove 22 to prevent seafood from leaking out along the gap.

[0038] Working method: During operation, a pair of support members 2 are brought together by half a rotation, the netting 3 covers the outer perimeter of the net frame 1, and the docking part 23 engages with the docking groove 24 to prevent seafood from being exposed along the gaps.

[0039] The limiting member 41 is fixedly connected to the limiting groove 42 by fasteners to prevent the pair of support members 2 from rotating freely.

[0040] At the same time, after squeezing the protruding structures 52 on both sides to deform and bend them, the elastic body 51 can be disassembled by pulling it out after the protruding structures 52 are disassembled. After disassembling the elastic body 51 in sequence, the mesh 3 and the support 2 can be separated.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
