Embodiment Construction

[0028] Attached below Figure 1-6 , the present invention is described in detail.

[0029] Such as Figure 1-3 As shown, the present invention is made up of multi-point mooring system 1, bottom frame 2, net body system 3 and water surface floating body system 4.

[0030] The multi-point mooring system 1 is composed of multiple sets of mooring foundations 1-1, anchor chains 1-2, buoys 1-3 and mooring cables 1-4. The mooring foundation 1-1 can be based on the actual geological type and pasture planning. Flexible selection of suction anchors, large grip anchors or gravity anchors, etc., for example, if the target sea area is sandy soil or clay with good bearing capacity, suction anchors can be used to reduce the sea area occupied by each cage; for sea conditions If the sea area is too harsh, a large holding force anchor can be used to prevent the anchor from slipping. The top of the mooring foundation 1-1 is hingedly connected to the anchor chain 1-2, the upper end of the anch...

Abstract

The invention provides a multi-point-mooring bottom tying net cage comprises a multi-point-mooring system, a bottom framework, a net body system and a water surface floating body system. The bottom tying net cage can be integrally towed in a self-floating mode and is convenient to install; the bottom framework can upwards float and downwards sink, so that the cultivation operation is flexible, convenient and fast. The multi-point-mooring bottom tying net cage cooperates with a cultivation boat or a central platform to perform cultivation operation, culture equipment for remote control, remotefeeding and the like is used, and a plurality of net cages are arranged for configuration, so that large-scale and intelligent cultivation can be realized, and economic benefits are improved.

Description

technical field [0001] The invention relates to a bottom net cage for underwater culture, in particular to a multi-point mooring bottom net cage suitable for deep sea culture. Background technique [0002] The development of marine ranching is inseparable from deep-sea net cage breeding equipment, which involves many engineering issues such as the anti-wave performance of the net cage, bait feeding, net cleaning, monitoring and operation convenience. In deep waters, the wind and waves are generally larger. In particular, the East my country Sea and the South China Sea are located in typhoon-prone areas, and the impact of wind and waves on the cage culture system is particularly obvious. The development of deep-sea cages is that Norway, the United States, and Japan are at the forefront of the world. [0003] The main forms of Norwegian cages are cylindrical cages made of HDPE and sinkable tension leg cages. The advantages of cylindrical mesh cages are low cost, simple stru...
