Abstract

The invention belongs to the technical field of ocean engineering equipment and discloses an elevating culturing net cage comprising a stand column structure, a truss structure, a stay bar structure, a floating drum structure and a fishing net sheet. The stand column structure comprises four or more stand columns; the truss structure is fixed on the four or more stand columns and comprises an upper truss fixed on the upper part of each stand column and a lower truss fixed on the lower part of each stand column; a stay bar is slantwise arranged between two adjacent stand columns; the floating drum structure is formed by floating drum main bodies and water loading devices; the floating drum main body is fixed on the lower ends of each stand column; the fishing net sheet is fixed on the stand column structure, the truss structure and the stay bar structure; each water loading device is disposed in each stand column to control water immersion depth and elevating operation of the net cage via a control of water amount in the floating drum main body; and a depth detection device is disposed in each stand column and connected with the water loading device to feed back depth detection data. The invention provides a deep-sea culturing net cage capable of resisting acute stormy waves.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a heaveable culture cage. Background technique [0002] The main structure of the existing deep water culture net cage is a gravity type HDPE net cage. [0003] Due to the light structure and low strength of the material, it is mainly installed in nearshore bays or semi-enclosed waters with islands and reefs as barriers. Generally, it can only withstand water flow below 0.5m / s. [0004] Under the water flow of 1m / s, 80% of the breeding capacity will be lost, and limited by the material and structure of HDPE cages, the maximum breeding volume can only be 7400 cubic meters. On the other hand, whenever the deep-water cage culture area is hit by a large wind and wave, the structural stability of the cage will be affected under the attack of waves and currents, and the culture volume will also be greatly lost. Especially when dealing with extreme weather such a...
