One-piece large raft culturing device

Abstract

The invention discloses an integrated large-scale raft type culture device. The culture device comprises a body and a fixed berthing device for fixing the body, wherein the body comprises a PE float of which the top is provided with a working platform, and at least six cantilevers connected with the side of the PE float. The PE float has a cavity; the cantilevers are radially arranged along the side of the PE float; an I-shaped steel bar is connected with the bottom end of the PE float; and a weight is connected with a cable on the underside of the I-shaped steel bar. The culture device has the advantages that: the device has a lower integral center and good stability, and realizes the function of controlling the culture water level conveniently; in addition, the culture device has simple operation, great culture space and high production efficiency; and the operating personnel can walk and patrol on the device so as to conveniently find out hidden dangers and carry out the harvest operation. The integrated large-scale raft type culture device has a reasonable structure, good stability, high culture efficiency, convenient patrol and harvest, and simple water level control.

Description

technical field [0001] The invention relates to an aquaculture device, in particular to an integrated large-scale raft culture device. Background technique [0002] Raft aquaculture has made an important contribution to my country's mariculture and is one of the main methods of mariculture in my country. Although the scale of raft farming in my country ranks first in the world, the types of farming involve algae (kelp, seaweed, asparagus, Eucheuma, agaric, hijiki), shellfish (scallops, oysters, mussels), abalone, There are dozens of species of ginseng, sea urchin, crab, etc. The aquaculture output accounts for more than half of the total domestic mariculture output, and the unit yield has also reached a relatively high level. However, most of my country's mariculture activities are currently concentrated in the near-shore -15-meter isobath In shallow waters, the waters between -15 and -40m isobaths have yet to be vigorously developed. However, due to the strong waves and rapi...

Although the scale of raft farming in my country ranks first in the world, the types of farming involve algae (kelp, seaweed, asparagus, Eucheuma, agaric, hijiki), shellfish (scallops, oysters, mussels), abalone, There are dozens of species of ginseng, sea urchin, crab, etc. The aquaculture output accounts for more than half of the total domestic mariculture output, and the unit yield has also reached a relatively high level. However, most of my country's mariculture activities are currently concentrated in the near-shore -15-meter isobath In shallow waters, the waters between -15 and -40m isobaths have yet to be vigorously developed. However, due to the strong waves and rapid currents in these sea areas, it is not easy to set up raft farming equipment. Research on wind and wave technology, expand new breeding space, and meet the major demand for the healthy and sustainable development of marine fisheries
