Definitions
- Multi-layered cages especially deep-water cages with multiple layers.
- the invention relates to a multi-layer net gear with a multi-layer structure net box, and a frame member and a structure thereof.
- the multi-layer net gear of the multi-layer net box is composed of a multi-layer sleeve type or a multi-layer horizontal layer-type net.
- the sheet structure is composed of frame members and structures made of plastic or metal materials with a certain strength and formed into a circular or polygonal structure, which can withstand the impact of wind waves with a certain strength. Background technique
- net cages especially deep-water net cages, are composed of a plastic frame floating on the water surface, nets equipped with reinforcement ropes, and vertically-oriented weight blocks.
- the upper part of the net is connected to the upper part of the plastic frame floating on the water, and the bottom of the net is connected by the guidance of the reinforcing rope and the vertically-oriented weight block to form a net box with a certain space for fish farming.
- benthic fishes such as sturgeon and sturgeon are mainly laid flat on the bottom of nets, and existing nets There is only one bottom of the net, which can not allow more benthic fish such as maggots and tadpoles to lie flat, so that the aquaculture volume cannot be expanded, and a large amount of water in the middle of the cage is almost idle, causing unreasonable waste.
- the invention provides a novel multi-layered net box net gear structure and net box frame structure, which can more reasonably and effectively utilize the water body space of the net box and overcome and solve the problems caused by the existing net box net gear and frame structure.
- the problem of inability to expand the breeding volume and breeding species can obviously increase the economic benefits of breeding.
- the technical solution adopted by the present invention to solve its technical problems is: ''
- FIG. 1 Vertical cage-type multilayer nets as shown in Figures 1, 2, and 3 are set in the cages, especially in the deep water cages.
- the shape of the nets can be cylindrical or polygonal. Structure, the bottom adopts the flat bottom mesh form, reinforcing ropes are set around each sleeve net to prevent cracking, and a weight ring for strengthening support and counterweight is set at the bottom.
- the upper part of the net is made of plastic with a certain buoyancy. It can also be made of metal pipes and used to fix multi-layer nettings.
- the nettings can be arranged in multiples in parallel or in multiple nested arrangements.
- a horizontally horizontally laminated multilayer netting as shown in FIG. 4 can also be provided.
- the shape of the netting is in the form of a flat bottom mesh, and a multilayer net is arranged in the longitudinal direction inside the peripheral netting.
- a reinforcing rope is provided on the mesh and the mesh to prevent cracking.
- a weight circle is provided in the middle area of the mesh to strengthen the support and weight. The weight circle should have a certain diameter and a certain through hole in the middle.
- the mesh and the peripheral netting are fixed by a rope connection method.
- a multilayer mesh can be set in the inner area of the cage, that is, it can be divided into multiple layers.
- FIG. 1, FIG. 2, and FIG. 3 are specific structural schematic diagrams of Embodiment 1 of a cage according to the present invention.
- Fig. 4 is a schematic diagram of a specific structure of a second embodiment of a net box according to the present invention.
- Figure 1, Figure 2, and Figure 3 are schematic diagrams showing the structure of the net box netting and frame of Example 1.
- Vertical cage-type multilayer nets as shown in Figures 1, 2, and 3 are set in the cages, especially in the deep water cages.
- the shape of the nets can be cylindrical or polygonal. Structure, the bottom is in the form of a flat-bottomed net, and reinforcing ropes are set around each sleeve net to prevent cracking.
- a bottom is provided to strengthen the support and has a certain weight, which can play a counterweight role and prevent nets.
- the weight circle floating at the bottom, the upper part of the net is made of plastic or metal pipe with a certain buoyancy, and is used to fix the multi-layer net.
- the net can be installed in multiple side-by-side arrangements, and it can also be multiple large and small.
- each sleeve type mesh can adopt single layer mesh or double layer mesh.
- a plastic or metal frame that can float on the water surface is made by electrofusion and electric welding methods, a sleeve net is made and reinforced with ropes, a weight ring is made, and then the sleeve net is formed.
- a plastic or metal frame that can float on the water The net gear and the weight ring are connected to form a complete sleeve net gear.
- the complete sleeve net gear is installed on the net box and fixed. If multiple sleeve nets are installed together, they are side-by-side structure, then they can be installed sequentially. For large and small inter-sleeve structure, in principle, they are installed from the bottom to the top and from the outside to the inside. .
- Fig. 4 is a schematic diagram showing the structure of the net gear and frame of the second embodiment.
- a horizontal and horizontal multilayer multilayer netting as shown in FIG. 4 is set.
- the shape of the netting adopts a flat-bottomed net.
- a multilayer net is arranged in the inner longitudinal direction of the peripheral net.
- a reinforcing rope is provided on the sheet to prevent rupture.
- a weight ring is provided in the middle area of the mesh to strengthen the support and weight. The weight ring should have a certain diameter and a certain through hole in the middle.
- Each layer of mesh and The outer nets are fixed by the method of rope connection. Multiple layers of the same piece can be set in the inner area of the cage, that is, they can be divided into multiple layers to improve the breeding efficiency.
- each piece of the multilayer mesh to be set is assembled and formed with a net clothes, a reinforcing rope and a connecting rope are installed, a weight ring is formed, and then each piece of the multilayer net is connected to the weight ring
- Each piece of netting is provided with a weight circle.
- Each piece of netting can use a single layer of netting or a double layer of netting, so as to form a complete multilayer laminated netting.
- Each piece of the laminated net gear is installed on the outer net gear of the net box from the bottom to the top and from the inside to the outside to form a novel multi-layer net box.
