Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an aquaculture net cage and a combined mooring chain. Background Technology

[0002] Currently, marine aquaculture cages are mainly floating aquaculture cages, including gravity cages and truss cages. All cages floating on the water surface need to be equipped with mooring systems to restrain the cages in a fixed sea area.

[0003] Gravity cages generally use polypropylene ropes for mooring. One end of the polypropylene rope is connected to the cage's floating frame, and the other end is connected to the seabed anchor. However, the polypropylene rope is smaller than seawater, so it will partially float on the sea surface, affecting the navigation of ships. Truss cages generally use metal anchor chains, which will not float on the water surface and affect the navigation of ships, but the cost is higher.

[0004] Therefore, it is necessary to design a mooring chain that is relatively low in cost and does not affect the safety of the vessel. Utility Model Content

[0005] The primary objective of this invention is to provide a modular mooring chain that does not affect the navigation of a vessel and is cost-effective.

[0006] Another objective of this invention is to provide an aquaculture cage employing the aforementioned combined mooring chain cable.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A composite mooring chain includes a surface chain, an underwater chain, and a submerged chain connected in sequence. The surface chain has a density greater than that of seawater and is made of nylon rope. The underwater chain has a density less than that of seawater. The submerged chain has a density greater than that of seawater and is made of abrasion-resistant material.

[0009] Preferably, the underwater cable is made of polypropylene rope.

[0010] Preferably, the submarine chain is made of metal anchor chain.

[0011] Preferably, the surface chain cable is bound and fixed to the underwater chain cable.

[0012] Preferably, the underwater cable is tied and fixed to the submarine cable.

[0013] This utility model relates to an aquaculture cage, including a cage body and the aforementioned combined mooring chain cable. The end of the surface chain cable away from the underwater chain cable is connected to the cage body, and the end of the seabed chain cable away from the underwater chain cable is used to anchor to the seabed.

[0014] Preferably, it also includes a seabed anchor, which is fixed to one end of the seabed chain cable away from the underwater chain cable, and the seabed anchor is used to anchor to the seabed.

[0015] Preferably, it also includes a counterweight, which is connected to the submarine chain or to one end of the underwater chain near the submarine chain.

[0016] Preferably, the counterweight is a stone.

[0017] Compared with the prior art, the combined mooring chain cable of this utility model embodiment has the following advantages:

[0018] In this invention, the combined mooring chain includes a surface chain, an underwater chain, and a submerged chain connected in sequence. The surface chain is used to connect to the cage body. Because the density of the surface chain is greater than that of seawater, and it is made of nylon rope, it will not float on the sea surface, thus not obstructing passing vessels and ensuring navigational safety. The underwater chain, with a density less than that of seawater, will not sink to the seabed and will not be damaged by friction with the seabed. The submerged chain is made of wear-resistant material and has a density greater than that of seawater, allowing it to sink to the seabed and preventing damage from friction. Simultaneously, the submerged chain also holds the underwater chain, preventing it from floating on the surface. Furthermore, the combined mooring chain is not entirely composed of metal anchor chains, thus reducing costs. Attached Figure Description

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] In the description of this utility model, it should be understood that the term "comprising" as used in this specification means the presence of the stated features, integers, steps, operations, parts, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts, components, and / or groups thereof. It should be understood that when we say a part is "connected" to another part, it can be directly connected to the other part, or there may be intermediate parts. The term "and / or" as used herein includes all or any unit and all combinations of one or more associated listed items.

[0023] like Figure 1 As shown, this utility model relates to a combined mooring chain cable, comprising a surface chain cable 1, an underwater chain cable 2, and a seabed chain cable 3 connected in sequence. The density of the surface chain cable 1 is greater than that of seawater and is made of nylon rope. The density of the underwater chain cable 2 is less than that of seawater. The density of the seabed chain cable 3 is greater than that of seawater and is made of wear-resistant material.

[0024] In this invention, the combined mooring chain includes a surface chain 1, an underwater chain 2, and a seabed chain 3 connected in sequence. The surface chain 1 is used to connect to the cage body 4. Because the density of the surface chain 1 is greater than that of seawater, and the surface chain 1 is made of nylon rope, it will not float on the sea surface, thus not obstructing passing ships and ensuring the safety of navigation. The underwater chain 2 has a density less than that of seawater, so it will not sink to the seabed and will not be damaged by friction with the seabed. The seabed chain 3 is made of wear-resistant material, and its density is greater than that of seawater, so it can sink to the seabed and is not easily damaged by friction with the seabed. Simultaneously, the seabed chain 3 can also hold the underwater chain 2, preventing it from floating on the sea surface. Furthermore, the combined mooring chain is not entirely composed of metal anchor chains, thus reducing costs.

[0025] It should be noted that, since the density of seawater is a range value, the density of surface cable 1 is greater than the above range value, the density of underwater cable 2 is less than the above range value, and the density of seabed cable 3 is greater than the above range value.

[0026] In this embodiment, the underwater cable 2 is made of polypropylene rope, so that the density of the underwater cable 2 is less than that of seawater, allowing the underwater cable 2 to float in the sea and not sink to the bottom, thus avoiding damage from friction with the seabed.

[0027] In this embodiment, the submarine chain 3 is made of metal anchor chain, so that the submarine chain 3 can sink to the seabed and has good wear resistance and is not easily worn by seabed friction.

[0028] In this embodiment, the surface cable 1 is tied to the underwater cable 2, and the underwater cable 2 is tied to the seabed cable 3, so that the surface cable 1, the underwater cable 2, and the seabed cable 3 are stably connected together in sequence.

[0029] This utility model also relates to an aquaculture cage, including a cage body 4 and the combined mooring chain cable, wherein the end of the surface chain cable 1 away from the underwater chain cable 2 is connected to the cage body 4, and the end of the seabed chain cable 3 away from the underwater chain cable 2 is used to anchor to the seabed.

[0030] By using the combined mooring chain cable to fix the cage body 4, it is ensured that the cage body 4 is restrained in a specific position and will not affect the passage of ships in the vicinity, thus ensuring safety and at a relatively low cost.

[0031] The aquaculture cage also includes a seabed anchor 5, which is fixed to the end of the seabed chain 3 away from the underwater chain 2. The seabed anchor 5 is used to anchor to the seabed, thereby stabilizing the combined mooring chain on the seabed and ensuring the stability of the aquaculture cage's position.

[0032] In this embodiment, the aquaculture cage also includes a counterweight 6, which is connected to the submarine chain cable 3 or to one end of the underwater chain cable 2 near the submarine chain cable 3, thereby resisting the influence of upward pulling force, avoiding anchor drift, and ensuring the stability of the aquaculture cage position.

[0033] Preferably, the counterweight 6 is a stone body to provide sufficient weight to resist the upward pulling force.

[0034] It should be noted that if the submarine chain cable 3 has sufficient weight to resist the upward pulling force, then the counterweight 6 is not required.

[0035] In summary, this utility model embodiment provides an aquaculture cage, which has the following technical effects:

[0036] 1. The surface chain cable is made of nylon rope with a density greater than that of seawater, so the surface chain cable will not float on the sea surface and will not affect the safety of the ship's navigation.

[0037] 2. The underwater chain cable is made of polypropylene rope, which has a density less than that of seawater, so the underwater chain cable will not sink to the seabed and will not rub against the seabed and wear out.

[0038] 3. The submarine chain cable uses metal anchor chains with a density greater than that of seawater, providing sufficient wear resistance and weight to ensure the stability of the aquaculture cages.

[0039] 4. The combined mooring chain cable includes surface chain cable, underwater chain cable and submarine chain cable. It takes into account the functional requirements of chain cables at different water depths and the mechanical properties of materials, and optimizes the stiffness and flexibility of the combined mooring chain cable, which can significantly improve the wind and wave resistance and safety of aquaculture cages.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
