Problems solved by technology

However, the domestically produced anti-wind and wave cages are mainly gravity-type cages. This type of cage is made of light materials. Although it has strong wind and wave resistance, it has poor tidal current resistance.
Due to the high flow velocity in most of the off-shore aquaculture areas in my country, some problems have occurred in the actual use of the above-mentioned cages: when the water flow exceeds a certain speed, the net clothing has a large displacement with the direction of the water flow, and the cultured fish have the habit of swimming against the current, so It is easy to cause damage to the fish body, which affects the safety of cage culture
In addition, at present, my country has not yet developed a wind and wave resistant cage that can better meet the needs of flounder and flounder with high economic value such as flounder and flounder.

Embodiment Construction

[0034] See first figure 1 and figure 2 To describe the first embodiment of the anti-storm net cage of the present invention.

[0035] The anti-wind and wave net cage of the present invention can be divided into three parts as a whole: frame structure, net body structure and anchoring structure.

[0036] The frame structure is located at the bottom of the whole net cage and is mainly composed of a horizontal ring member 11 . The horizontal annular member 11 can be made into a polygon (as shown in this embodiment), and it can be made into other shapes, such as a circle and the like. In the center of the horizontal ring member 11, an intermediate connecting ring 12 is arranged, and a plurality of frame ropes 13 are connected between the intermediate connecting ring 12 and the horizontal ring member 11. In order to adjust the tension of the frame rope 13, as image 3 As shown, at the joint between the frame rope 13 and the horizontal ring member 11 , a threaded turnbuckle 14 ...

Abstract

A wind and wave resistant netted case is composed of a frame structure consisting of horizontal ring member, central linking ring and rope system, a net body structure attached to said frame structure and comprising horizontal net, lateral net and netted cover, and an anchor structure consisting of multiple anchors, multiple anchor ropes, and buoyages.

Description

technical field [0001] The invention relates to a net cage for cultivating fish, shellfish and crabs in water, in particular to a wind and wave-resistant net cage which can meet the technical requirements for cultivating flounder and flatfish and which can resist the influence of wind waves and red tides. Background technique [0002] At present, the number of seawater cages in my country has grown to nearly 1 million, of which more than 2,000 domestically produced anti-wind and wave cages have been produced. However, the domestically produced anti-wind and wave net cages are mainly gravity-type net cages. This type of net cage is made of light materials. Although it has a strong ability to resist wind and waves, it has poor tidal current resistance. Due to the high flow velocity in most of the off-shore aquaculture areas in my country, some problems have occurred in the actual use of the above-mentioned cages: when the water flow exceeds a certain speed, the net clothing ha...
