Embodiment 1

[0029] Such as Figure 1-5 As shown, the marine ecological breeding combination net cage includes at least two culture net cages 10 combined by fixed components 30, the culture net cage 10 includes a polygonal main floating platform 13, and the bottom surface of the main floating platform 13 is fixed and vertically arranged The sealing buoy 14, the bottom of the sealing buoy 14 is coaxially connected to the row of buoys 15, the bottom of each row of buoys 15 is connected to the bottom frame 16 corresponding to the shape of the main floating platform 13, the bottom frame 16, the sealing buoy 14 and the inlet Net clothes 40 are all arranged on the float column 15 of the row, and the water permeable holes 152 arranged crosswise are all established on the side and the bottom surface of the float column 15 of the inlet row. Semi-suspension ball 151.

[0030] The present invention utilizes fixing assembly 30 to carry out fixed connection between breeding net cages 10 so that there ...

Embodiment 2

[0040] Net clothing 40 used among the present invention is prepared by following method:

[0041] 1) Put 95 parts of the above-mentioned polyethylene, 5 parts of zinc oxide and 6 parts of titanium dioxide in parts by weight into a mixer and stir evenly for 50 minutes;

[0042] 2) Put the evenly stirred mixture into the reactor, add 10 parts of light calcium carbonate, 3 parts of sodium dithionite, 6 parts of cuprous oxide, and 3 parts of styrene. The temperature is controlled at 95°C to 105°C, and the reaction time is 10-12 minutes;

[0043] 3) Add the reacted mixture into an extruder and extrude to obtain the netting 40.

[0044] The netting 40 prepared by the present invention has the characteristics of high strength, high abrasion resistance, strong oxidation resistance, and strong toughness. During the preparation process, sodium dithionite is used to prevent carbonyl compounds from being produced in the mixture, so as to solve the problem of the netting after being illum...

Embodiment 3

[0046] The marine ecological breeding combined net cage of the present invention uses steps in water:

[0047] 1) Assemble a single breeding cage 10: the main floating platform 13, the auxiliary floating platform 12, and the inner baffle 11 are integrated components. The bottom surface of the floating body 13 is fixedly installed with a sealing floating column 14, an inlet and a row floating column 15, and then the base frame 16 is used to cover the bottom, and then the matching assembly 20 is installed. Aquaculture production is estimated during this period based on the number and weight of the weights 24 removed.

[0048] 2) Assembly: Assemble the fixed plate 32 to the sealing floating column 14, where the assembly can choose to process the opening of the fixed plate 32 and the sealing floating column 14, and then weld the opening on the fixed plate 32, and then install the required quantity The fixing plate 32 of the fixing plate 32, the positioning column 33 is installed ...

Abstract

The invention provides a marine ecological culture combined net cage and belongs to the technical field of aquaculture equipment. The marine ecological culture combined net cage comprises at least twoaquaculture net cage units combined through fixing modules; every aquaculture net cage unit comprises a polygonal main floating platform, the bottom surface of the main floating platform is fixedly connected vertically arranged sealing floating columns, the bottom of every sealing floating column is coaxially connected with an inlet and drainage floating column, the bottom surface of every inletand drainage floating column is connected with a bottom rack corresponding in shape to the main floating platform, the bottom racks, the sealing floating columns and the inlet and drainage floating columns are provided with nets, the side surfaces and the bottom surface of the inlet and drainage floating columns are provided with water holes arranged in a crossed mode, the number of the water inlet holes of the inlet and drainage floating columns is greater than that of the water outlet holes of the inlet and drainage floating columns, and the inlet and drainage floating columns are internallyprovided with semi-floating balls. The marine ecological culture combined net cage connects the aquaculture net cage units through combination, is high in wind and wave resistance, and can achieve wave-induced floatation reducing effects and a self-cleaning function, thereby high in stability in water.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a combined net cage for marine ecological cultivation. Background technique [0002] Deep-sea aquaculture cages refer to aquaculture cages that can be used in relatively deep sea areas (generally, the water depth of the sea area is >20m). It is a brand-new aquaculture facility developed in the past ten years. There are Norway, the United States, Chile, Scotland, Canada, Greece, Turkey, Spain, Australia and other countries. [0003] Deep-sea cages can be divided into floating cages and lifting cages. Lifting cages float on the water surface when the weather is calm, and sink underwater when a typhoon comes to avoid the impact of wind and waves. Sea cage culture is currently the In a mature traditional industry, engineering plastic pipes with better mechanical properties and economical efficiency are generally selected as the floating frame material of...
