The invention provides a design method of an assembly process of a large-scale aquaculture fishery netting 2 with a ship-shaped truss structure, which comprises the following steps
Building a truss 1 structure: the truss 1 is an outer cubic inner inverted trapezoidal structure formed by main floating steel pipes 7; the U-shaped rings 9 are arranged on the inner sides of the main floating steel pipes 7 at the top and the bottom of the inner side of the truss 1;
fixing the netting 2: the netting 2 is hung on the inner side of the truss 1 and is installed in a matching way with u-shaped rings 9 at the top and the bottom of the inner side of the truss 1 through a longitudinal steel rope arranged on the periphery of the netting 2; the netting 2 penetrates through the u-shaped ring 9 from the bottom to the top in sequence and is tightly installed.
Four corners of the netting 2 are broken edges to form a quadrilateral structure with long four edges, four missing corners and short edges; the section of the netting 2 is trapezoidal; the netting 2 forms an included angle of 30-60 degrees with the vertical surface; the longitudinal steel rope arranged at the bottom of the netting 2 is a bottom steel rope.
The main floating steel pipe 7 at the top of the truss 1 is also provided with a handrail frame 8; four groups of u-shaped rings 9 are arranged along the inner side of the truss 1 along the circumferential direction and are respectively arranged on the inner side of the upper end of the handrail tube of the handrail frame 8, the inner side of the lower end of the handrail tube of the handrail frame 8, the inner side of the top main floating steel tube 7 and the inner side of the bottom main floating steel tube 7; four sets of u-shaped rings 9 are positioned corresponding up and down, and 36 u-shaped rings 9 are arranged in each set.
The longitudinal steel ropes arranged on the top of the netting 2 comprise a lower tying frame rope 5, a middle tying frame rope 4 and an upper tying frame rope 3; the lower tying frame rope 5 is tied and tightened on the U-shaped ring group at the inner side of the top main floating steel pipe 7; the middle tying rope 4 and the upper tying rope 3 are tied inside the lower end of the handrail tube and inside the upper end of the handrail tube in turn.
The middle and upper tether ropes 4 and 3 are located above the water surface at the tether point of the netting 2.
The included angle between the upper tying frame rope 3 and the vertical direction is 58-62 degrees when the upper tying frame rope reaches a stable state; the included angle between the middle tying frame rope 4 and the vertical direction is 88-92 degrees when the middle tying frame rope reaches a stable state; the angle between the lower tying frame rope 5 and the vertical direction is 43-48 degrees when the lower tying frame rope is tied up to a stable state.
The installation distance between the upper part of the netting 2 and the top main floating steel pipe 7 is more than 0.5m, and the installation distance between the bottom end of the netting 2 and the bottom main floating steel pipe 7 is more than 1.0m.
In one embodiment of the present invention, the netting 2 further comprises a side netting;
net bottom: the netting is connected with the lower edge of the side netting and is positioned at the bottom of the net cage.
And (3) preventing the net from jumping: the upper part of the net on the truss 1 is connected with the upper edge of the side net and is vertical to the horizontal plane.
Longitudinal lacing line: a steel cable assembled for strengthening the strength of the middle or the sewing part of the netting and avoiding the breakage of the netting.
Transverse lacing line: the steel cable assembled for strengthening the strength of the middle or the sewing part of the netting and avoiding the breakage of the netting forms a closed rope loop.
Rope tying: the net cage is fixed with a floater and a rope for tying and hanging the sinker.
Outline: a steel cable for reinforcing the edge of the netting.
In the invention, in order to avoid serious deformation of the netting 2 under the action of heavy waves and strong currents, which causes friction between the netting and the main structure of the truss 1 in a fishing ground and damages, so that fish escape and serious culture loss are caused, a certain safety distance needs to be reserved between the netting 2 and the inner side edge of the truss 1, and the upper end and the lower end of the netting 2 are connected and fixed with the upper end and the lower end of the truss 1, so that the netting is prevented from deforming.
In the present invention, the lower tying frame rope 5 is the main stressed rope, and the middle tying frame rope 4 and the upper tying frame rope 3 are stressed less to avoid the guardrail from bearing excessive force.
Further, the middle tying frame rope 4 and the upper tying frame rope 3 are positioned above the water surface at the tying point of the net, so that the shape of the net is maintained, and the fish is prevented from escaping. After the lower tying frame rope 5 is broken due to overlarge external force, the middle tying frame rope 4 and the upper tying frame rope 3 are stressed again, so that the netting is prevented from forming a gap immediately, and the cultured fishes are prevented from escaping and losing a large amount. So main atress rope is tied and is tied up on main superficial steel pipe 7, and upper, middle and lower system frame rope connected system makes the netting 2 keep breeding space and netting 2 bulk strength have multiple guarantee.
In one embodiment, the angle between the upper tether rope 3 and the vertical direction is 60 ° when the upper tether rope reaches the steady state; the included angle between the middle tying frame rope 4 and the vertical direction is 90 degrees when the middle tying frame rope reaches a stable state; the angle between the lower tying frame rope 5 and the vertical direction is 45 degrees when the tying is in a stable state.
Preferably, enough long tying ropes are led out from the cross ropes at the bottom of the net and penetrate through the U-shaped ring 9 of the main floating steel pipe 7 to be fastened to the U-shaped ring 9 of the upper main floating steel pipe 7, so that the bottom of the net 2 can be opened, and the side ropes of the net 2 can be tightened to form a fixed culture space.
Furthermore, a net cover is arranged, so that the net cover can be directly tied on the handrail frame 8 of the main structure of the fishing ground after the fishing ground sinks conveniently.
In one embodiment, the length of the bottom end tying rope of the netting 2 is about 10 meters and is larger than the height 7m of the truss 1, and the bottom end tying rope of the netting 2 passes through the bottom U-shaped ring 9 of the truss main body structure, vertically passes through the top U-shaped ring and is tied at the position of the main floating pipe 7 beside the U-shaped ring 9. This is done to tighten the bottom of the netting 2 and avoid the bottom of the netting 2 from being flexibly deformed and rubbing against the truss structure at the bottom of the truss 1 under the action of strong current.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
