Embodiment

[0012] Example: refer to Figure 1 to Figure 3 , sinking bottom lifting net cage, comprising a sinking bottom net cage body 1 with a rigid main frame 11, wherein: the top of the main frame 11 is connected with a truss-shaped floating frame 12; the inside of the sinking bottom net cage body 1 is connected with a closed net Garment 13; the lower side of the rigid main frame 11 is connected with a traction cable 14; the traction cable 14 is also connected with a self-sinking base with a retractable control assembly 18; the retractable control assembly 18 can retract the traction cable 14 as required to control the self-sinking base and The distance between the rigid main frame 11. By retracting and retracting the control assembly 18, retracting the traction cable 14 to control the distance between the self-sinking base and the rigid main frame 11, the commercial fish can be harvested and stocked as required. The outer side of the rigid main frame 11 is connected with the anchor ...

Abstract

The invention discloses a submergence lifting net cage comprising a submergence net cage body provided with a rigid main frame, wherein a prismatic floating frame is connected to the upper part of the main frame; a closed mesh is connected to the inner side of the submergence net cage body; a traction cable is connected to the lower side of the rigid main frame; the traction cable is further connected with a self-submergence base provided with a coiling and uncoiling control component; the coiling and uncoiling control component can be used for controlling the distance between the self-submergence base and the rigid main frame by coiling and uncoiling the traction cable according to needs. The coiling and uncoiling control component is used for coiling and uncoiling the traction cable to control the distance between the self-submergence base and the rigid main frame in order to harvest and breed commercial fish according to demand. The outer side of the rigid main frame is connected with an anchor rope through the traction cable to form an array system for facilitating management. The invention has the advantages of needing no counterweight system, and being convenient to manage, good in wave and current resistance, constant in aquatic water volume and suitable for breeding middle and lower fishes.

Description

technical field [0001] The invention relates to a rigid bottom-sinking deep-water net cage, in particular to a bottom-sinking lifting net cage. Background technique [0002] The breeding cage is composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. Wherein the mooring system is the foundation of the cage in the water, once the mooring fixing system has problems in windy and wave weather, it will cause the whole cage to be damaged due to uneven stress. At present, there are three common cage mooring forms at home and abroad: one is the traditional multi-point mooring; the other is the surface grid mooring; the third is the underwater grid mooring. The traditional multi-point mooring system is simple in form. At present, this method is mostly used in coastal floating deep-water cages in my country. In multi-point mooring, there are three types of anchors according to different sea areas. One is pile anchors, which ar...
