Turbot cultivation net cage having anti-pollution function

Abstract

The invention discloses a turbot cultivation net cage having an anti-pollution function, and relates to a turbot cultivation net cage. The turbot cultivation net cage uses a hot-dip galvanized iron pipe, a cylindrical plastic foam floating ball, a high-strength single fast knot polyethylene net, a high-strength nylon warp knitting net, an anti-pollution copper alloy rhombus net, a high-strength fishing polyethylene rope, an ultrahigh-strength rope and high-strength fishing lines and is characterized in that: a net cage floating support is welded into a top frame and a bottom frame by using the hot-dip galvanized iron pipe; the cylinder plastic foam floating ball under the lower surface of the bottom frame of the floating support is coated with waterproof cloth and a small-mesh waste netting; a netting system for the net cage consists of a double-layer synthetic fiber netting serving as a first netting and the anti-pollution copper alloy rhombus net serving as a second netting; the first netting and the second netting are connected in a vertical half-soft mode; the net bottom of the net cage is hung with a square galvanized iron pipe framework with edges of 5.0 meters; and the net cage floating support is connected with a floating rope frame through a cable and tied on a berth fixing system.

Description

technical field [0001] The invention relates to a breeding cage in the technical field of turbot. Background technique [0002] Turbot farming is an important part of aquaculture. Ordinary synthetic fiber rope netting materials and net clothing used in turbot breeding cages are seriously stained and attached during breeding production, resulting in unsmooth water exchange inside and outside the cage, affecting the normal growth and development of turbot and breeding benefits. There are many times of changing the net and the labor intensity of changing the net is relatively high, the raw material consumption of the rope net is large, and the box net will be discarded by the farmer after it is damaged. Ordinary aluminum alloy nets, stainless steel nets or barbed wire materials used in turbot breeding cages will experience serious direct wear and tear between the cage culture and the metal floating frame of the metal cages, resulting in severe sea damage after several months o...

Problems solved by technology

Ordinary synthetic fiber rope netting materials and net clothing used in turbot breeding cages are seriously stained and attached during breeding production, resulting in unsmooth water exchange inside and outside the cage, affecting the normal growth and development of turbot and breeding benefits. There are many times of changing the net, and the labor intensity of changing the net is relatively high, the raw material consumption of the rope net is large, and the netting of the box body will be discarded by the farmers if it is damaged.

Ordinary aluminum alloy nets, stainless steel nets or barbed wire materials used in turbot breeding cages will experience serious direct wear and tear between the cage culture and the metal floating frame of the metal cages, resulting in severe sea damage after several months of use in harsh sea conditions. There will be a serious accident of damage to the metal mesh net cage for mariculture, which restricts the popularization and use of the metal mesh cage for mariculture; common aluminum alloy mesh, stainless steel mesh or wire mesh materials have corrosion and fouling problems in seawater It also seriously restricts the popularization and use of metal net clothing cages for marine aquaculture

During the development of turbot breeding net cages, some problems need to be solved urgently, such as the antifouling problem of cage netting, low cage volume retention, serious drift of net level, and energy consumption of synthetic fiber netting. problems, serious direct wear between the metal netting and the metal floating frame, the corrosion problem of the metal floating frame, and the selection of the optimal height of the turbot breeding cage, etc. These problems have long been a problem in the field of turbot technology. Unresolved technical problems, there is an urgent need for a net with lower energy consumption, better antifouling function, smaller net level drift, higher box volume retention rate, which can improve the economic benefits of cage culture and net cage culture. Cage culture cages for turbot culture without room for development of cage culture and improving the level of cage facilities and equipment
