Embodiment 1

[0073] Embodiment 1: as Figure 2~Figure 13 As shown, 8 mooring rings 5 ​​are evenly and symmetrically arranged on the bottom net frame 4, correspondingly using 8 steel wire ropes 11 to moor between the bottom net frame 4 and the cage frame 1, and the length of the sleeve 8 is about 1 / 4 of net depth, net cage uses 32 sleeves 8 altogether. The schematic diagram of the proposed device after installation is shown in Figure 11 shown.

Embodiment 2

[0074] Embodiment 2: 12 mooring rings 5 ​​are evenly and symmetrically arranged on the bottom net frame 4, and 12 steel wire ropes 11 are used correspondingly to moor between the bottom net frame 4 and the cage frame 1, and the length of the sleeve 8 is about For 1 / 3 of net depth, net cage uses 36 sleeves 8 altogether.

[0075] According to the above ideas, more embodiments can be derived, which are not exhaustive here.

Abstract

The invention discloses a flow-resistant net-cage system with a separable bottom net and side net. The system comprises an anchoring foundation and a net-cage frame, the side net is installed on the lower side of the net-cage frame, the bottom net comprises a bottom net frame, bottom netting is bound to the interior of the bottom net frame, the bottom of the side net is bound to the outer periphery of the bottom frame of the bottom net, and a closed aquaculture space is formed by the side net and the bottom net; multiple steel wires are bound to the bottom net frame at intervals, each steel wire is sequentially sleeved with multiple sleeves connected with each other and placed in net-cage netting, and the upper ends of the steel wires are fastened to the net-cage frame. According to the net-cage system, the bottom net frame is a rigid frame and can control and restrain the side net, so that the volume loss rate of the netting is lowered; assembly and disassembly of the bottom net and the side net can be achieved, so that all kinds of aquaculture operations are convenient; the multiple steel wires sleeved with the sleeves are bound to the inner side of the net-cage system, so that the aquaculture space is effectively maintained; the bottom net is pulled up based on the steel wires by equipment, so that a load transmission path is provided for net pulling workload reduction.

Description

Technical field: [0001] The invention relates to seawater culture net cages, and more specifically relates to a flow-resistant net cage system with detachable bottom nets and side nets. Background technique: [0002] The netting of the cage can be divided into side nets and bottom nets according to the positional relationship, and the side nets and bottom nets are connected to each other to form a closed breeding space. Generally, the bottom net of traditional cages cannot be disassembled, such as figure 1 shown. Regarding the technical development of seawater cages, the following issues deserve attention: [0003] 1. Cleaning of side net and bottom net: [0004] A large number of larvae and spores of marine organisms and microorganisms can move with the current and attach to the seawater anti-wave net cage, which reduces the water exchange inside and outside the box and deteriorates the breeding environment, resulting in frequent fish diseases in the cage culture, and al...
