Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture equipment technology, specifically to a deep-sea aquaculture enclosure that is easy to assemble. Background Technology

[0002] With the increasing depletion of marine fishery resources, deep-sea aquaculture, as a sustainable method of marine resource development, has gradually attracted widespread attention. As a crucial facility in deep-sea aquaculture, the structural design, material selection, and installation method of deep-sea aquaculture enclosures directly impact aquaculture efficiency, cost control, and service life.

[0003] Currently, traditional deep-sea aquaculture enclosures mostly use steel or concrete structures. While these structures possess a certain degree of strength and stability, they also present numerous problems. First, steel structures are susceptible to seawater corrosion in the deep-sea environment, resulting in high maintenance costs and a limited lifespan. Second, concrete structures are heavy, difficult to transport and install, have long construction periods, and cause significant impacts on the marine environment.

[0004] In recent years, with the development of polymer materials technology, polyolefin materials have been increasingly used in marine aquaculture equipment due to their advantages such as corrosion resistance, light weight, and high strength. However, existing aquaculture fences using polyolefin materials still have shortcomings in structural design (such as Chinese utility model patent 202320478975.X, "A Novel Hinged Floating Aquaculture Fence"), including complex structures, complex connection methods, low assembly efficiency, and poor structural stability, making it difficult to meet the requirements of high strength, high stability, and easy assembly for deep-sea aquaculture fence structures. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides an easy-to-assemble deep-sea aquaculture enclosure. The enclosure has a simple structure, a simple connection method, is easy to assemble, has good structural stability, and high strength.

[0006] The technical solution adopted to achieve the above-mentioned objectives of this utility model is as follows:

[0007] An easy-to-assemble deep-sea aquaculture enclosure includes a net frame and an operating platform. Both the net frame and the operating platform are closed-loop structures, with the net frame located inside the operating platform. The net frame is fixed to the operating platform by multiple evenly distributed connectors. The net frame is formed by connecting multiple first polyolefin pipe segments end to end in sequence through first pipe segment joints, and the operating platform is formed by connecting multiple second polyolefin pipe segments end to end in sequence through second pipe segment joints.

[0008] Both the mesh support frame and the work platform are hexagonal in shape.

[0009] The netting support and the working platform are distributed on the same plane, and the centers of gravity of the netting support and the working platform are the same.

[0010] The first pipe section joint includes a first pipe body made of polyolefin material and a first covering sleeve made of rubber material. The first pipe body is a straight or elbow. The two ends of the first pipe body are respectively inserted into and bonded to the closer ends of two adjacent first polyolefin pipe sections. The first covering sleeve is respectively wrapped around the connected first pipe body and the first polyolefin pipe section, and the first covering sleeve is bonded to the connected first pipe body and the first polyolefin pipe section respectively.

[0011] The second pipe section connector includes a second pipe body made of polyolefin material and a second covering sleeve made of rubber. The second pipe body is a straight or elbow type. Both ends of the second pipe body are respectively inserted into and bonded to the closer ends of two adjacent second polyolefin pipe sections. The second covering sleeve is respectively wrapped around the connected second pipe body and the connected second polyolefin pipe section, and the second covering sleeve is respectively bonded to the connected second pipe body and the connected second polyolefin pipe section.

[0012] The first covering sleeve is in the form of a two-step structure. The side with the larger inner diameter of the first covering sleeve covers one end of the corresponding first pipe body, and the corresponding end face of the corresponding first pipe body abuts against the shoulder of the first covering sleeve. The side with the smaller inner diameter of the first covering sleeve covers the corresponding first polyolefin pipe section.

[0013] The second sheath is in the form of a two-step structure. The side with the larger inner diameter of the second sheath covers one end of the corresponding second pipe body, and the corresponding end face of the corresponding second pipe body abuts against the shoulder of the second sheath. The side with the smaller inner diameter of the second sheath covers the corresponding second polyolefin pipe section.

[0014] One or more rubber sealing rings are provided between the first pipe fitting body and the corresponding first polyolefin pipe section.

[0015] The connector is provided with a first mounting hole that mates with the first polyolefin pipe section and a second mounting hole that mates with the second polyolefin pipe section. The diameter of the first mounting hole is smaller than that of the second mounting hole. The mesh support passes through each of the first mounting holes, and the corresponding first polyolefin pipe section on the mesh support is interference-fitted with the corresponding first mounting hole. The working platform passes through each of the second mounting holes, and the corresponding second polyolefin pipe section on the working platform is interference-fitted with the corresponding second mounting hole.

[0016] The connector is a one-piece molded structure and is plate-shaped.

[0017] The connector consists of a horseshoe-shaped first plate and a curved second plate. The straight edge of the first plate opposite its curved edge is connected to the edge of the second plate where the chord is located. The straight edge of the first plate opposite its curved edge and the edge of the second plate where the chord is located have the same length. The first mounting hole is opened on the side of the first plate facing away from the second plate, and the second mounting hole is opened on the second plate and at the connection between the second plate and the first plate.

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

[0019] 1. The fence's mesh support and working platform are both closed-loop structures formed by connecting multiple polyolefin pipe segments end to end. When connecting the polyolefin pipe segments, in addition to using pipe fittings for ordinary plug-in and adhesive connections, rubber-coated rings are also wrapped around the pipe fittings and polyolefin pipe segments. The coated rings are then glued to the pipe fittings and polyolefin pipe segments respectively. The adhesive force of the glue and the shrinkage force of the rubber securely connect the pipe fittings and polyolefin pipe segments. This connection method is not only simple and easy to assemble, but also reliable, increasing the structural stability of the mesh support and working platform.

[0020] 2. When connecting the netting support and the work platform, the fence uses an integrally molded plate connector. Only two mounting holes are opened on the integrally molded plate connector. The fence is connected to the netting support and the work platform through the two mounting holes using an interference fit. This connection method is simple, easy to assemble, improves assembly efficiency, and also improves the structural strength and reliability of the fence. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] The easy-to-assemble deep-sea aquaculture enclosure provided in this embodiment is as follows: Figure 1 As shown, the system includes a netting support 1 for suspending the netting and a work platform 2 for aquaculture operations (such as stocking and raising seedlings, and feeding). Both the netting support 1 and the work platform 2 are hexagonal in shape. The netting support 1 is located inside the work platform 2 and is fixed to the work platform by six connectors 6. The six connectors 6 are evenly distributed on the outer circumference of the netting support 1. More connectors 6 can be added to make the connection between the netting support 1 and the work platform 2 more secure. The netting support 1 and the work platform 2 are located on the same plane, and their centers of gravity are the same.

[0029] The mesh support 1 is composed of multiple first polyolefin tube segments 101 (length 1-12m, dn160-630mm, SDR11-21) connected end-to-end via first tube segment joints. The hollow cavity of the mesh support 1 is filled with a density of 0.3-0.5g / cm³. 3 The closed-cell foam prevents water from entering the hollow cavity of the mesh support 1, thus preventing the mesh support 1 from losing buoyancy. The first pipe section joint includes a first pipe body 3 made of polyolefin material and a first covering sleeve 4 made of fluororubber. The first pipe body 3 can be a straight pipe or an elbow. When the frame of the mesh support 1 needs to be assembled through the first polyolefin pipe section 101, a straight pipe is selected as the first pipe body 3. When the two frames of the mesh support 1 need to be assembled and connected, a 120° elbow is used as the first pipe body 3.

[0030] Both ends of the first pipe body 3 are respectively inserted into the closer ends of two adjacent first polyolefin pipe sections 101. Five evenly distributed sealing rings 5, made of nitrile butadiene rubber (HNBR), are provided between the first pipe body 3 and the corresponding first polyolefin pipe section 101. The sealing rings 5 ​​enhance the sealing effect between the first pipe body 3 and the first polyolefin pipe section 101. Adhesive is applied to the inside of both ends of the first pipe body 3, and the adhesive is used to bond the first pipe body 3 to the two adjacent first polyolefin pipe sections 101, strengthening the connection between the first pipe body 3 and the first polyolefin pipe section 101 and enhancing the stability of the mesh support structure 1.

[0031] The first covering sleeve 4 is respectively wrapped around the first pipe body 3 and the first polyolefin pipe segment 101. The first covering sleeve 4 is in a two-step shape. The side of the first covering sleeve 4 with a larger inner diameter wraps around one end of the corresponding first pipe body 3, and the corresponding end face of the first pipe body 3 abuts against the shoulder of the first covering sleeve 4. The side of the first covering sleeve 4 with a smaller inner diameter wraps around the corresponding first polyolefin pipe segment 101. Adhesive is applied to the inner wall of the first covering sleeve 4, and the first covering sleeve 4 is bonded to the first polyolefin pipe segment 101 and the first pipe body 3 by the adhesive. The adhesive force of the adhesive and the shrinkage force of the first covering sleeve 4 enhance the reliability of the connection between the first pipe body 3 and the first polyolefin pipe segment 101, further increasing the structural stability of the mesh support 1.

[0032] The working platform 2 is composed of multiple second polyolefin pipe sections (1-12m in length, DN400-800mm, SDR11-21) connected end-to-end via second pipe section joints, with a filling density of 0.3-0.5g / cm³ within the hollow cavity of the working platform. 3 The closed-cell foam prevents water from entering the hollow cavity of the work platform 2, thus preventing the work platform 2 from losing buoyancy. The second pipe section joint includes a second pipe body made of polyolefin and a second sheath made of fluororubber. The second pipe body can be a straight pipe or an elbow. When the frame of the mesh support needs to be assembled through the second polyolefin pipe section, a straight pipe is selected as the second pipe body. When the two frames of the mesh support need to be assembled and connected, a 120° elbow is used as the second pipe body.

[0033] Both ends of the second pipe fitting body are inserted into the closest ends of two adjacent second polyolefin pipe sections. Five evenly distributed sealing rings, made of nitrile butadiene rubber (HNBR), are provided between the second pipe fitting body and the corresponding second polyolefin pipe sections to enhance the sealing effect between them. Adhesive is applied to the inside of both ends of the second pipe fitting body to bond it to the two adjacent second polyolefin pipe sections, strengthening the connection and enhancing the stability of the mesh support structure.

[0034] The second sheath is respectively wrapped around the connected second pipe fitting body and the second polyolefin pipe section. The second sheath is in a two-step shape, with the side of the second sheath with a larger inner diameter covering one end of the corresponding second pipe fitting body, and the corresponding end face of the second pipe fitting body abutting against the shoulder of the second sheath. The side of the second sheath with a smaller inner diameter covers the corresponding second polyolefin pipe section. Adhesive is applied to the inner wall of the second sheath, and the second sheath is bonded to the second polyolefin pipe section and the second pipe fitting body using the adhesive. The adhesive force of the adhesive and the shrinkage force of the second sheath enhance the reliability of the connection between the second pipe fitting and the second polyolefin pipe section, further increasing the structural stability of the working platform.

[0035] The connector 6 is a one-piece injection-molded structure, and the connector 6 is plate-shaped as a whole. The connector 6 consists of a horseshoe-shaped first plate 601 and a curved second plate 602. The straight edge of the first plate 601 opposite its curved edge connects to the edge of the second plate 602 where the chord is located, and the lengths of the straight edge of the first plate 601 opposite its curved edge and the edge where the chord of the second plate 602 is located are the same. A first mounting hole 7 is provided on the side of the first plate 601 facing away from the second plate 602, and the first mounting hole 7 is close to the curved edge of the first plate 601. A second mounting hole 8 is provided on the second plate 602 and at the connection between the second plate 602 and the first plate 601, and the diameter of the first mounting hole 7 is smaller than that of the second mounting hole 8.

[0036] The mesh support 1 passes through each of the first mounting holes 7, and the corresponding first polyolefin pipe segment 101 on the mesh support 1 is interference-fitted with the corresponding first mounting hole 7. The working platform 2 passes through each of the second mounting holes 8, and the corresponding second polyolefin pipe segment on the working platform 2 is interference-fitted with the corresponding second mounting hole 8. The connector is an integral injection-molded structure.

[0037] The one-piece injection-molded connector 6 avoids the weak connection point problem caused by traditional connection methods (such as bolts, welding, and hinges). The connector forms a firm bond with the netting bracket 1 and the working platform 2, significantly improving the strength and reliability of the overall fence structure. In addition, the one-piece injection-molded connector 6 saves assembly steps, reduces assembly time, and improves assembly efficiency.

[0038] The assembly method for the aforementioned easy-to-assemble deep-sea aquaculture enclosure is as follows:

[0039] 1. First, prefabricate the first polyolefin pipe section 101, the second polyolefin pipe section, the connector 6, the first pipe body 3, the first covering sleeve 4, the second pipe body, the second covering sleeve, and the sealing ring 5;

[0040] 2. An ROV (Remotely Operated Vehicle) is used to assemble the netting support frame and work platform at a designated location in the ocean. When assembling frame A of netting support 1, the first polyolefin pipe segment 101 is connected using a first pipe segment connector with a straight connector. When assembling the first polyolefin pipe segment T101 (marked for ease of understanding) that requires the installation of connectors, one end of the first polyolefin pipe segment T101 is connected first, and then the connector 6 is fitted onto the first polyolefin pipe segment T101. When assembling another adjacent frame B of netting support 1, the first polyolefin pipe segment 101 is connected to one end of frame A using a first pipe segment connector with an elbow. The connection method for frame B is the same as for frame A.

[0041] 3. The assembly method of the work platform 2 is the same as that of the mesh support 1. When assembling the work platform 2, the first second polyolefin pipe segment is passed through any connector 6 connected to the mesh support, and then the work platform 2 is assembled according to the method in step 2. When assembling the work platform 2, pay attention to connecting the corresponding second polyolefin pipe segment to the corresponding connector 6 connected to the mesh support 1.

[0042] 4. After the fence is assembled, lower it to the predetermined depth and then fix it with counterweight chains.
