Description

Technical Field

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

[0002] Cage aquaculture is a fish farming method conducted in waterways. Its overall structure includes a frame, netting, floats, sinkers, and cables. The frame can be made of metal, wood, or bamboo, and its design must consider resistance to wind and waves. The netting includes the net skirt, net bottom, net cover, and feeding channels, and its design comes in various forms, such as square, octagonal, and hexagonal.

[0003] After prolonged use, the netting exhibits aging and wear, requiring replacement. For example, Chinese Patent Publication No. CN118177122A discloses a netting replacement device for laid-out gabion cages, comprising: a cylindrical gabion cage, a new netting laying support, an old netting recovery support, and a central rotating shaft. The new netting laying support and the old netting recovery support are connected to the cylindrical gabion cage via the central rotating shaft and rotate around the cage. During rotation, the old netting cage is replaced simultaneously. The old netting recovery support rotates first to recover the old netting, and the new netting laying support follows behind to lay the new netting. This invention uses the cooperation of two supports to complete the overall replacement of the gabion cage netting, achieving integrated and mechanized netting replacement.

[0004] In practice, the netting on three sides is replaced by rotating shafts on three sides. Both the netting before and after replacement are connected to the main body of the net cage by netting clips. The netting is fixed by clips. In windy and wavy weather or when the fish fry move around, the netting may come loose, resulting in poor stability. Furthermore, the netting is not easy to assemble or disassemble from the rotating shafts. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of assembling and disassembling the netting and the loose fixing of the netting, and to propose a deep-sea aquaculture netting replacement device.

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

[0007] Design a deep-sea aquaculture net replacement device, including a net cage body and a replacement device. A central floating platform is provided at the bottom of the net cage body, and the replacement device is provided on the side of the net cage body and at the bottom of the central floating platform.

[0008] The replacement device includes a laying component and a winding component. The laying component and the winding component are respectively equipped with a new net and an old net through a winding roller. The new net and the old net are connected by a connector.

[0009] Furthermore, the laying assembly includes a pair of laying cylinders, which are respectively fixedly connected to the side of the main body of the cage and the bottom of the central floating platform. The winding rollers are rotatably connected inside the pair of laying cylinders, and the pair of winding rollers are respectively in the form of a rod-shaped structure and a frustum-shaped structure.

[0010] Furthermore, the winding assembly includes a pair of winding drums, which have the same structure as the laying drum and are symmetrically arranged therebetween. A through groove is provided between the opposite sides of the laying drum and the winding drum, and the new net and the old net are respectively disposed in the corresponding through grooves.

[0011] Furthermore, a first guide groove is provided between the opposite sides of the upper and lower ends of the main body of the net cage, and a second guide groove is provided on the bottom surface of both the main body of the net cage and the central floating platform. Guide blocks are fixedly connected to both sides of the new net and the old net.

[0012] The new net and the old net located on the side are slidably connected to the first guide groove via the guide block;

[0013] The new net and the old net located at the bottom are slidably connected to the second guide groove via the guide block.

[0014] Furthermore, the connector includes a pair of chains, and a connecting portion is provided around the periphery of the take-up roller. One of the chains is fixed to the other side of the connecting portion, and the other chain is fixed to one end of the new net and the old net. The chains on adjacent sides are engaged and clamped together by chain heads.

[0015] The new net is fixed to the other end of the old net by the connector.

[0016] Furthermore, the pair of take-up rollers rotate synchronously through a drive assembly, which includes a motor. The motor is fixedly connected to the top of both the laying drum and the take-up drum located on the side. One end of the take-up roller located on the top is fixedly connected to the shaft end of the motor, and the other end is fixedly connected to a first bevel gear.

[0017] Furthermore, a second bevel gear is fixedly connected to the end of the take-up roller located at the bottom, and the first bevel gear meshes with the second bevel gear to rotate.

[0018] The beneficial effects of the deep-sea aquaculture net replacement device proposed in this utility model are as follows: This utility model connects the new net and the old net through a connector. The advantage is that by synchronously driving a pair of winding drums and laying drums through the drive component, the old net on the side and bottom can be wound up at the same time, and the new net can be pulled to lay. It is convenient and quick to replace the net at the same time. Furthermore, the connector allows for quick disassembly and assembly between the new net, the old net and the winding drum, which is convenient for replacing damaged nets or disassembling and cleaning the nets. It also avoids the need to connect the winding drum when replacing the nets. The structure is simple and highly practical. Attached Figure Description

[0025] 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.

[0026] Reference Figure 1-5 A deep-sea aquaculture net replacement device includes a net cage body 1 and a replacement device 2. A central floating platform 3 is provided at the bottom of the net cage body 1, and the replacement device 2 is provided on the side of the net cage body 1 and at the bottom of the central floating platform 3.

[0027] The replacement device 2 includes a laying component 21 and a winding component 22. The laying component 21 and the winding component 22 are respectively provided with a new net 4 and an old net 5 through a winding roller 23. The new net 4 and the old net 5 are connected by a connector 6.

[0028] It should be added that the bottom of the main body 1 of the net cage is connected to the seabed by ropes and anchors, and a support frame is fixedly connected between the upper and lower ends of the main body 1 of the net cage.

[0029] Furthermore, the laying assembly 21 includes a pair of laying cylinders 211, which are respectively fixedly connected to the side of the net cage body 1 and the bottom of the central floating platform 3. The winding rollers 23 are rotatably connected inside the pair of laying cylinders 211, and the pair of winding rollers 23 are respectively in the form of a rod-shaped structure and a frustum-shaped structure.

[0030] It is worth mentioning that connecting rods are fixedly connected to the upper and lower ends of the main body 1 of the net cage, as well as between the bottom of the main body 1 of the net cage and the central floating platform 3. The laying cylinder 211 and the winding cylinder 221 are detachably connected to the connecting rods through hose clamps.

[0031] Furthermore, the take-up roller 23 with a bottom has a frustum-shaped structure, and its diameter gradually decreases along the direction of the central floating platform 3.

[0032] Furthermore, the winding assembly 22 includes a pair of winding drums 221, which have the same structure as the laying drum 211 and are symmetrically arranged therebetween. A through groove is provided between the opposite sides of the laying drum 211 and the winding drum 221, and the new net 4 and the old net 5 are respectively disposed in the corresponding through grooves.

[0033] More specifically, a first guide groove 11 is provided between the opposite sides of the upper and lower ends of the main body 1 of the net cage, and a second guide groove 12 is provided on the bottom surface of both the main body 1 of the net cage and the central floating platform 3. Guide blocks 13 are fixedly connected to both sides of the new net 4 and the old net 5.

[0034] The new net 4 and the old net 5, which are located on the side, are slidably connected to the first guide groove 11 via the guide block 13;

[0035] The new net 4 and the old net 5 located at the bottom are slidably connected to the second guide groove 12 via the guide block 13.

[0036] In general, the connector 6 includes a pair of chains 61, and the outer periphery of the take-up roller 23 is provided with a connecting part 231. One of the chains 61 is fixed to the other side of the connecting part 231, and the other chain 61 is fixed to one end of the new net 4 and the old net 5. The chains 61 on adjacent sides are engaged and clamped together by chain heads 62.

[0037] The new net 4 and the other end of the old net 5 are fixed together by the connector 6.

[0038] It should be noted that, normally, a new net 4 is arranged around the take-up roller 23 inside the laying cylinder 211, and the new net 4 is connected to the old net 5 on the outside of the net box body 1 through a connector 6. When the old net 5 is wound up, it pulls the new net 4 to lay it. After the new net 4 and the old net 5 are unlocked and separated through the connector 6, the take-up cylinder 221 can be disassembled and the old net 5 can be taken out for replacement. The connecting part 231 is a cloth, which is fixed on the outside of the take-up roller 23 and can pass through the through groove on the outside of the take-up cylinder 221 and the laying cylinder 211 to connect with the new net 4 or the old net 5.

[0039] When the old net 5 needs to be wound up and the new net 4 needs to be laid, the motor 71 drives the winding rollers 23 on both sides to rotate. Of course, the rotation direction of the shaft ends of the pair of motors 71 is the same. While one motor 71 is unwinding, the other motor 71 is winding up. A sealing box is provided around the motor 71. The sealing box is sealed to the winding drum 221 and the laying drum 211.

[0040] The main body 1 of the cage has a ring structure, and the guide block 13 can be provided with ball bearings on both sides to reduce friction with the guide groove;

[0041] It should be noted that both the first guide groove 11 and the second guide groove 12 have openings on the side near the take-up roller 23. The inner side of the opening is provided with positioning glass beads. The guide block 13 is installed through the opening and is prevented from detaching by abutting against the positioning glass beads.

[0042] Furthermore, the pair of take-up rollers 23 rotate synchronously through a drive assembly 7, which includes a motor 71. The top of the laying drum 211 and the take-up drum 221 located on the side are both fixedly connected to the motor 71, and one end of the take-up roller 23 located on the top is fixedly connected to the shaft end of the motor 71, while the other end is fixedly connected to a first bevel gear 72.

[0043] Finally, the end of the take-up roller 23 located at the bottom is fixedly connected to a second bevel gear 73, and the first bevel gear 72 meshes with the second bevel gear 73 to rotate.

[0044] In specific operation, when the motor 71 drives the take-up roller 23 to rotate, the side take-up roller 23 drives the bottom take-up roller 23 to rotate synchronously through the first bevel gear 72 and the second bevel gear 73, and then the bottom take-up roller 23 lays the new net 4 at the bottom.

[0045] It is important to note that, such as Figure 4 As shown in the diagram, it is for reference only. In actual practice, the first bevel gear 72 and the second bevel gear 73 have the same structure to ensure that the rotation speed is the same and that the netting on one side does not roll up too fast.

[0046] Working method: During operation, a pair of motors 71 rotate synchronously, driving the take-up rollers 23 to rotate. One take-up roller 23 rotates to unwind the new net 4, and the other take-up roller 23 rotates to wind up the old net 5. The new net 4 and the old net 5 slide under the guidance of the guide block 13.

[0047] Furthermore, while the take-up roller 23 rotates, the bottom take-up roller 23 is driven to rotate synchronously through the first bevel gear 72 and the second bevel gear 73, and then the bottom take-up roller 23 lays the new net 4 at the bottom.

[0048] Then, the new net 4 is separated from the old net 5 by separating a pair of chains 61 through the sliding chain head 62, and then the winding drum 221 is disassembled for replacement.

[0049] 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.
