Open sea suspended culture cage

Abstract

The invention relates to a floating culture net cage in an open sea area. The first floating tube and the second floating tube are arranged correspondingly up and down, and the first net is installed between the first floating tube and the second floating tube and is installed corresponding to the bottom of the breeding net cage. On the second floating tube, the column is fixed on the first floating tube. The operation platform is supported above the first floating tube by the column. The main structure of the cage is set and connected at intervals in the circumferential direction, and floating balls are respectively connected to the anchor chains. The main structure of the breeding cage is adjusted with the sea level fluctuation through the cooperation between gravity and buoyancy to adjust the height of the operation platform in a wave-like environment. Above the energy zone, the first buoyant tube is below the wave energy zone. The invention realizes the height adjustment of the breeding net cage following the sea level fluctuation, ensures the actual effective breeding volume of the breeding net cage, prevents the main structure of the breeding net cage from being affected by the impact of the seawater wave energy area, and improves the performance of the breeding net cage against typhoon .

Description

technical field [0001] The invention belongs to the technical field of aquaculture net cages, in particular to an open sea area suspension type aquaculture net cage. Background technique [0002] Existing a kind of suspension type culture net cage, the casing structure of culture net cage is anchored by anchor chain and floats in seawater, and existing this suspension type culture net cage mainly has the following deficiencies: [0003] First, because the culture net cage cannot effectively adjust its position in the seawater with the ebb and flow of seawater, part of the culture space of the culture cage is above the water surface at low tide, resulting in the actual effective culture space of the cage reduce; [0004] Second, with the rise and fall of the sea level due to the ebb and flow of seawater, the main structure of the existing aquaculture cages cannot effectively avoid being in the wave energy zone of the seawater, so the waves will directly impact the main struc...

Problems solved by technology

[0003] First, because the culture net cage cannot effectively adjust its position in the seawater with the ebb and flow of seawater, part of the culture space of the culture cage is above the water surface at low tide, resulting in the actual effective culture space of the cage reduce;

[0004] Second, with the rise and fall of the sea level due to the ebb and flow of seawater, the main structure of the existing aquaculture cages cannot effectively avoid being in the wave energy zone of the seawater, so the waves will directly impact the main structure of the aquaculture cages, which increases the number of aquaculture cages. The risk of the main structure of the cage being damaged by the impact of wind and waves

As a result, the ability of aquaculture cages to resist typhoons is relatively weak. Generally, they need to be attached to islands and reefs for construction, which is not suitable for open sea areas with stronger typhoons, which limits the construction and application of aquaculture cages in open sea areas.
