Description

TECHNICAL FIELD

[0002] With the development of marine fishery breeding in China, the demand for breeding net cages is changing towards deep sea and large scale. In the open sea area with water depth of 30-50 meters, the traditional floating net cage is difficult to resist the wind and wave in the severe sea conditions such as typhoon in this kind of sea area, so it is of great significance to study and design the bottom-sitting net cage for fishery production activities in deep sea area. The current deep sea breeding net cage often damages due to the collision between the net cloth and other structures of the net cage, and in severe cases, it will lead to fish escape and cause huge economic losses. In order to prevent the collision between the net cloth and the net cage, the existing bottom-sitting net cage usually adopts the net cloth structure with an inclination angle and loads a pre-tension on the net cloth, which can limit the deformation range of the net cloth, but the net cloth system with an inclination angle will reduce the breeding water of the net cloth, and the excessive pre-tension of the net cloth will make the net cloth bear greater load in extreme sea conditions and cause damage to the net cloth.
