Abstract

The utility model provides a fixed net cage, which comprises a square box body composed of six net sheets 3. The utility model is characterized in that four iron chains 1 are respectively fixed on four sides at the bottom of the box body; four side edges of the box body are respectively provided with a plurality of sleeve rings 2; each of four corners on the bottom surface of the box body is respectively fixed on one end of each of four roots of hanging ropes 4 in corresponding; four roots of pile rods 5 are respectively sheathed in the sleeve rings 2 on the four side edges of the box body. The utility model has the advantages of simple structure, low cost and wind and wave resistant, and is suitable to be used in the sea area of shallow sea of which the water depth is from 1.2 meters to 3 meters during the low tide of all silt quality base.

Description

Fixed net cage

The utility model relates to a kind of aquaculture utensil, specifically a kind of fixed net cage.

We know that marine cage fish culture is low because of its aquaculture cost, efficient is high, manageability, generally adopted in the coastal area, but the net cage that uses at present are floating cage that the capacity of anti-storm extreme difference is so cage culture is only limited to the less narrow and small zones of stormy waves such as inner bay.

The purpose of this utility model is exactly to provide a kind of simple structure in order to overcome above-mentioned the deficiencies in the prior art, and cost is low, wind wave resistance, be adapted at all argillo arenaceous at the bottom of, the fixed net cage that uses of time of low water depth of water 1.2-3 rice shallow sea area.

For achieving the above object, the utility model can be realized by following measure, form square box by six net sheets 3, four limits of bottom half are fixed with an iron chains 1 respectively, four sides of casing are respectively equipped with a plurality of collars 2, the corresponding respectively end with four lifting ropes 4 in four angles of tank floor is fixed, and four pile bars 5 are enclosed within respectively in the collar 2 of four sides of casing.

The utility model is simple in structure, and cost is low, and wind wave resistance is adapted at multiple sea area and uses.

The utility model will be further described by embodiment below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

As can be seen from Figure 1, the utility model casing is sewed up by six net sheets 3 and is formed square structure, four limits of tank floor are fixed with an iron chains 1 respectively, four sides of casing are fixed with a plurality of collars 2 respectively, four angles of tank floor are corresponding respectively to link to each other with an end of four lifting ropes 4, be with a pile bar 5 in the collar 2 of four sides of casing respectively, the utility model four pile bars 5 upper ends are respectively equipped with lifting device 6, and lifting device 6 links to each other with lifting rope 4 other ends.

When the utility model uses, at first make a call to four armored concrete concrete stakes in the seabed according to the size and the shape of net cage, then four pile bars 5 are separately fixed on the concrete stake, drive lifting device 6 according to culturing needs, lifting rope 4 can draw high the net cage bottom, net cage is compressed, the same lifting device 6 that discharges relies on iron chains 1 own wt that the sinking of net cage bottom, net cage are stretched.

Claims

1, a kind of fixed net cage, be provided with the square box of forming by six net sheets (3), four limits that it is characterized in that bottom half are fixed with an iron chains (1) respectively, four sides of casing are respectively equipped with a plurality of collars (2), the corresponding respectively end with four lifting ropes (4) in four angles of tank floor is fixed, and four pile bars (5) are enclosed within respectively in the collar (2) of four sides of casing.
