Multi-way shunt lift type net cage

Abstract

The invention discloses a multi-way shunt lift type net cage. The multi-way shunt lift type net cage comprises an inflating frame, wherein a hexagonal buoyancy force adjusting pipe is arranged on the side of the inflating frame; a hexagonal structure pipe is arranged at the lower end of the inflating frame; an inflating inclined pipe is arranged on the side of the inflating frame from top to bottom and is communicated with the buoyancy force adjusting pipe; meshed clothes is hung on the inner side of the inflating frame; the lower end of the meshed clothes is connected with a sinker; and a hexagonal shunt cover is arranged at the periphery of the part between the buoyancy force adjusting pipe and the structure pipe of the inflating frame. The hexagonal shunt cover serves as a shunt structure and still can segment the water flow in each direction under the action of the water flow, so that the action force of the water flow to the meshed clothes is reduced and the effective culture water body in the meshed clothes and the culture capacity are increased. The multi-way shunt lift type net cage has the advantages of high shunt efficiency, good anti-wave anti-flow effect, low cost, convenience for operation, large effective culture capacity, high reliability and environment friendliness.

Description

technical field [0001] The invention relates to a breeding device, in particular to a multi-directional shunting lifting net cage. Background technique [0002] As a traditional farming method, shallow water cage culture is mainly concentrated in semi-enclosed bays. Affected by economic interests, the density of shallow-water cage culture in some coastal areas of China is relatively high, resulting in poor water flow and severe hypoxia in some cultured water bodies. In addition, residual bait and fish excrement cannot be quickly transported out with the water body, resulting in the environmental capacity of the cultured water body. The overload phenomenon is serious. This farming method not only pollutes the water quality of sea areas, but also affects the quality of farmed fish, and has also become one of the main factors that induce coastal red tides. Therefore, it is the only way for the sustainable development of cage culture to gradually transfer the cage culture from...
