Floated aquaculture net cage in open sea

Abstract

The invention relates to a floated aquaculture net cage in an open sea. A first floating pipe and a second floating pipe are vertically correspondingly arranged. A first mesh is mounted between the first floating pipe and the second floating pipe, and the corresponding aquaculture net cage bottom is mounted on the second floating pipe. A stand column is fixed to the first floating pipe, an operation platform is supported above the first floating pipe through the stand column, the height of a second mesh is extendable, and the bottom of the second mesh and the first mesh are combined. Anchor chains are arranged in the circumferential direction of the main structure of the aquaculture net cage at intervals, and are connected, floating balls are arranged on the anchor chains respectively, thefollow-up height of the anchor chains is adjusted along with rising and falling of the sea level through cooperation of gravity and buoyancy, the operation platform is located above a wave energy area, and the first floating pipe is located below the wave energy area. According to the floated aquaculture net cage, the follow-up height is adjusted along with rising and falling of the sea level, the actual and effective aquaculture volume of the aquaculture net cage is guaranteed, the main structure of the aquaculture net cage is prevented from being impacted and influenced by the seawater waveenergy area, and the typhoon resisting performance of the aquaculture net cage is improved.

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.
