Technical Field
[0001] The utility model relates to the technical field of offshore fishery aquaculture, in particular to a conveniently installable net sheet applied to a cage truss. Background Art
[0002] Cage aquaculture is the main method of offshore fishery product aquaculture at present. With the rapid development of cage aquaculture technology, offshore fishery aquaculture has also obtained huge benefits. However, due to the relatively harsh offshore environmental conditions, problems such as the enrichment of marine organisms on the netting, damage and aging of the netting are likely to occur during the long-term service of cage aquaculture at sea. Once the netting is damaged, it is easy for fish to escape, causing serious economic losses.
[0003] At present, the net sheets of offshore aquaculture cages mainly rely on tying the opposite side ropes to the cage trusses, which have problems such as long cage construction periods, large net sheet installation workloads, and difficulties in replacing net sheets underwater, seriously restricting the development of the offshore aquaculture industry. Therefore, a conveniently installable net sheet is of great significance for promoting the development of offshore fishery aquaculture. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems of large existing net sheet installation workload and difficulty in underwater replacement, and provide a conveniently installable net sheet applied to a cage truss, which can realize the convenient installation and disassembly of the net sheet and the aquaculture cage, greatly improve the efficiency of net sheet installation, reduce the difficulty of underwater net sheet replacement, and reduce the manufacturing and maintenance costs of aquaculture cages.
[0005] To achieve the above purpose, the technical solution provided by the utility model is: a conveniently installable net sheet applied to a cage truss, including a net sheet main body, and further including an extended net sheet, a limiting plate and a connecting piece. Among them, one end of the extended net sheet is woven together with the net sheet main body, and the other end is divided into two layers of net sheets, which are respectively called the first layer of net sheet and the second layer of net sheet. The limiting plate is fixed on the cage truss, and the first layer of net sheet and the second layer of net sheet are detachably fastened on both sides of the limiting plate through the connecting piece.
[0006] Further, the extended net sheet covers the limiting plate.
[0007] Further, the limiting plate is provided with limiting holes for installing the connecting piece.
[0008] Further, the connecting piece includes a nut, a sealing plate, a stud and a gasket. There is at least one stud, which is vertically fixed on the sealing plate. The stud is provided with an external thread for installing the nut. After the stud passes horizontally through the corresponding holes of the two layers of net sheets and the limiting plate, a backing plate and a nut are used to clamp and fix the two layers of net sheets. Among them, the first layer of net sheet is clamped between the sealing plate and the limiting plate, and the second layer of net sheet is clamped between the gasket and the limiting plate.
[0009] Furthermore, the main mesh is a wear-resistant and corrosion-resistant non-metallic mesh, and the mesh size thereof is matched with the types of aquatic products to be cultured.
[0010] Furthermore, the main mesh is a mesh made of ultra-high molecular weight polyethylene.
[0011] Furthermore, the extension mesh is a wear-resistant and corrosion-resistant non-metallic mesh, the strength thereof is greater than that of the main mesh, and the mesh holes thereof are subjected to anti-wear and tensile strengthening treatments.
[0012] Furthermore, the extension mesh is a mesh made of ultra-high molecular weight polyethylene.
[0013] Furthermore, the non-fixed end of the limiting plate is subjected to chamfering and polishing treatments to ensure that its surface is smooth and clean.
[0014] Furthermore, the connecting member is a nylon material part.
[0015] Furthermore, the nut is a hexagonal nut.
[0016] Compared with the prior art, the present utility model has the following advantages and beneficial effects:
[0017] 1. The extension mesh and the main mesh are of the same material and process, which is convenient for processing.
[0018] 2. The whole mesh is light in weight and convenient to carry.
[0019] 3. The connection by studs and nuts is convenient for installation and replacement.
[0020] 4. The mesh and the connecting member are made of non-metallic materials, which are corrosion-resistant by themselves and there is no influence of additional corrosion caused by the potential difference between the mesh and the steel structure of the net cage.
[0021] 5. The limiting plate is covered by the extension mesh, and the marine organisms attached to the mesh will fall off along with the disassembly and replacement of the mesh, and there is no need to clean the marine organisms on the limiting plate when installing again.
[0022] 6. The extension mesh is closely attached to the limiting plate. Even if the netting undergoes creep, the limiting plate can still perform the function of preventing fish from escaping.
[0023] 7. The two layers of the extension mesh are tightly fixed between the sealing plate and the limiting plate and between the gasket and the limiting plate, avoiding the situation that the stress is concentrated on individual net lines, resulting in large deformation or even breakage of the net lines.
