Example 1
The embodiment provides a green-mouth aquaculture net, please refer to fig. 1 to 4, which comprises two net sheets, wherein the side edges of the two net sheets are sewn to form a net bag capable of accommodating aquaculture objects in an expanded state;
the mesh comprises a plurality of round silk single chains 100 arranged at intervals along the length direction of the mesh, a plurality of flat silk strips 200 arranged at intervals along the width direction of the mesh, and a plurality of cotton yarns arranged between two adjacent flat silk strips 200 along the width direction of the mesh;
two adjacent flat silk strips 200 and two adjacent round silk single chains 100 form the main mesh unit of the aquaculture net, and the cotton yarns divide the main mesh unit into the secondary mesh units.
The single round wire chain 100 is formed by connecting a plurality of chain rings in series, and the material is preferably polyethylene or other material having high weather resistance, and as an example of polyethylene, referring to fig. 4, the single round wire chain 100 is formed by connecting a plurality of polyethylene rings in series, and the shape of the polyethylene rings may be circular or elliptical, for example. The chain structure facilitates the penetration of the flat filament 200. The flat filament strip 200 may be threaded through the round filament single chain 100 in various ways, for example, it may be threaded through one of the chain loops, then folded back and threaded through the adjacent chain loop, or may be threaded through the chain loops several times in order to further strengthen the connection. Because the polyethylene has stronger corrosion resistance, the round single-chain 100 can be kept from corrosion and rotting for a long time after being soaked in a corrosive environment (such as seawater) for a long time. In addition, the chain structure has high strength and high bearing capacity.
The above-mentioned flat filament strip 200 is preferably made of polyethylene or other materials with strong weather resistance, for example, the flat filament strip 200 is a flat strip, has good flexibility and weather resistance, and can be kept from corrosion and rotting for a long time after being immersed in a corrosive environment (for example, seawater) for a long time. The flat filament 200 may be inserted, for example, in the following manner: and all the round single-chains 100 sequentially penetrate through one of the net sheets, the edges of the two net sheets are locked by bending, knotting and the like, then all the round single-chains 100 penetrate through the other net sheet in the opposite direction, and after the penetration, the round single-chains extend downwards along the length direction of the breeding net to repeat the weaving action again, and the weaving is repeated in a circulating way until the required length is woven.
Above-mentioned, cotton yarn sets up between two adjacent flat strand silk 200 along the width direction of net piece for reduce main mesh unit, form secondary mesh unit, it is obvious that secondary mesh unit is less than main mesh unit, and cotton yarn can prevent that breed thing (for example blue or green mouth seedling) from easily losing the problem emergence of omitting from main mesh unit because the seedling undersize when the juvenile phase because the seedling. Because the weather resistance of cotton yarn is relatively poor, about 3 to 6 weeks in about soaking, the cotton yarn can automatic degradation to the secondary mesh unit of breed net disappears, remains the major network pore unit, and the major network pore unit can adapt to the breed in thriving and strong growing period to the demand in culture space, avoids the normal growth of too narrow and small secondary mesh unit restriction breed thing. The cotton yarn can be threaded in various ways, for example, the cotton yarn between two adjacent round single-chain 100 goes around and turns back. The method specifically comprises the following steps: after passing through the chain hole of one round silk single chain 100, the cotton yarn extends towards the adjacent round silk single chain 100 and passes through the chain hole of the adjacent round silk single chain 100, after the threading is finished, the cotton yarn turns back to the position below the initial round silk single chain 100 in the opposite direction, and then the threading action is sequentially repeated, and the cotton yarn is circularly reciprocated and gradually goes downwards until the required length is woven. For another example, a piece of cotton yarn sequentially passes through all the round single-chain filaments 100 of the mesh, turns back to the lower side of the original round single-chain filament 100 in the opposite direction after the threading is completed, and then sequentially repeats the above actions, and circulates back and forth and gradually goes down until the required length is woven.
The main mesh unit is preferably formed of two adjacent flat filament strands 200 and two adjacent round filament strands 100, and the main mesh unit is preferably rectangular in shape, and the size of the main mesh unit can be set according to the adult state of the culture.
The secondary mesh unit is formed by separating the primary mesh unit by cotton yarn. The shape of the secondary mesh unit can be, for example, a rectangle, a quadrangle or other irregular shapes according to the way of putting cotton yarns in. More preferably, the secondary mesh unit has a quadrangular shape.
As described above, the side edges of the two meshes are sewn, for example, the two round single-chains 100 are locked by the flat filament 200, and the flat filament 200 sequentially passes through the chain holes of the round single-chains 100 of the two meshes in the length direction of the aquaculture net to achieve the purpose of locking. For another example, the side edges of the two meshes are formed by twisting a plurality of strands of strip-shaped braids, and the twisting manner is various and is not described in detail herein.
