Embodiment 1

[0027] Such as Figure 1-9As shown, a staggered double-column flexible shallow sea aquaculture seine net includes a post pile 3 connected to the seabed, a main net 4 connected to the post post 3, and the post posts 3 are arranged alternately on both sides of the main net 4, and the main net 4 The cross section is "X" shape, the intersection point is connected by the rope 1, and the floating ball 2 is arranged on the rope 1, the upper part of the main net 4 is connected with the upper end of the column pile 3 through the lasso 6, and the lower part of the main net 4 is connected with the pole by the lasso 6. The lower end of the pile 3 is connected to the buried seabed, and the main net 4 is fixed with a double-layer net 7 between the high tide level and the low tide level, and the double-layer net 7 is a large mesh foot net. This technical solution can avoid the accumulation and entanglement of the seine net at different tidal levels, which will damage the net clothing, and pl...

Embodiment 2

[0029] Such as Figure 2-9 As shown, a staggered double-column flexible shallow sea aquaculture seine net includes a post pile 3 connected to the seabed, a main net 4 connected to the post post 3, and the post posts 3 are arranged alternately on both sides of the main net 4, and the main net 4 The cross section is "X" shape, the intersection point is connected by the rope 1, the upper part of the main net 4 is connected with the upper end of the pile 3 through the lasso 6, and the lower part of the main net 4 is connected with the lower end of the pile 3 through the lasso 6 and buried in the seabed. 3 is fixed to the seabed through the pile foundation 5, and the column pile 3 is fixed to the pile foundation 5 through the fixing device 8. This technical scheme adopts double-column piles with staggered openings to connect the main net 4, so that the stress on the steel rope 1 is more uniform, the stability and the wind and wave resistance of the overall structure of the breeding...

Embodiment 3

[0038] The working principle of the staggered double-column flexible shallow sea aquaculture seine of the present invention is as follows: the piles 3 of the present invention are arranged staggeredly on both sides of the main net 4, so that the stress on the line rope 1 is more uniform, and the stability of the overall structure of the aquaculture seine is improved. At the same time, the flexibility of the net can be fully utilized, and the reasonable ratio of the pile distance can make the resistance of the pile group smaller, the shielding effect is greater, and the ability of the pile to resist sea currents is enhanced. The section of the main net 4 is "X " shape, the intersection point is connected by the line rope 1, the length of the main net 4 in the lower part of the "X" shaped intersection of the main net 4 is equal to the vertical distance between the upper and lower ends of the main net 4, so that the net clothing of the main net 4 is flexible at low tide After the ...

Abstract

The invention discloses a cross-opening double-column flexible shallow sea culture purse seine, belonging to the technical field of purse seine culture devices. The culture purse seine comprises column piles connected with a seabed and a main net connected with the column piles, wherein the column piles are staggered at two sides of the main net, the cross section of the main net is x-shaped, intersection points are connected through a steel rope, the upper part of the main net is connected with upper ends of the column piles through through lassos, the lower part of the main net is connectedwith the lower ends of the column piles through lassos and is embedded into the seabed, the column piles are fixed with the seabed through pile foundations, and the column piles are fixed with the pile foundations through fixing devices. The culture purse seine provided by the invention can prevent the purse seine from being piled up and wound at different tide levels to avoid damage to nettings,and has the functions of protecting the nettings and preventing the nettings from intertwining with each other; therefore, the stress of the steel rope is more uniform, and the stability and the windwave resistance of the whole structure of the culture purse seine are improved; and the culture purse seine is simple in construction, economic and environment-friendly, and has the advantages of universality and sustainability.

Description

technical field [0001] The invention belongs to the technical field of purse seine culture devices, in particular to a staggered double-column flexible shallow sea aquaculture seine. Background technique [0002] my country's seawater cage culture started in the 1970s. In recent years, the scale of cage culture has developed rapidly. The shallow sea seine culture project is a typical marine facility culture model. The piles are directly tied and vertically fixed, which requires high design requirements for pile resistance, tensile fracture resistance and tilt resistance, and the economic cost is also high, and it is easy to cause damage in extreme weather conditions, while the suspension type and The floating rope seine type is more suitable for small and medium-sized aquaculture sea areas, and it is difficult to apply to large-scale and large-scale aquaculture projects. [0003] Prior art, such as the Chinese invention patent with the authorized announcement number CN 103053...
