Abstract

The utility model discloses a steel combined deepwater mesh box capable of sinking and floating, which is a polygon tower structure formed by connecting a plurality of steel unit bent frames end to end. A heavy block is hung on a fishing net on the lower surface of a frame; the bent frames are the tower structure made of steel by connecting fixedly; the bottom part of each unit bent frame is longitudinally provided with a plurality of float tubes with intervals; the float tubes are communicated and connected by respective valves and steel pipe systems and are finally connected to the respective valves of a float through hoses. The utility model can freely lift, descend, and suspend in water according to environmental change of the water; the utility model also has the advantages of simple and stable assembly of the frame of the mesh box, anti-wind wave performance, strong anti-red tide performance, simple structure, and convenient installation.

Description

The steel combined type deep water mesh cage that can rise and fall

Technical field

The utility model relates to the fish culture device, especially a kind of shallow sea deep water fish culture cage.

Background technology

Cage culture is an intensive aquaculture, and traditional floating mat formula net cage is owing to the problem at aspects such as rack intensity, connected modes, and the ability of opposing typhoon and red tide is relatively poor.In addition, general net cage can only bubble through the water column or be suspended under water, and the sink-float inconvenient operation of net cage owing to reasons such as requirement of culturing and seasonal variation, requires net cage to rise and fall easily.Such as typhoon, when red tide arrives, certain depth then makes net cage emerge to avoid net cage breakage and fish kills after typhoon, the red tide again to require to sink under water to net cage.From the round deep water mesh cage of Norway's gravity type of external introduction, though certain superiority is arranged on technology and structure, this net cage investment is big, cost is high, and the fisherman is difficult to bear, so it is bigger to promote difficulty.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, economical and practical steel combined type deep water mesh cage that can rise and fall.

For achieving the above object, the technical solution adopted in the utility model is: the polygonal frame formula structure that it comprises several steel unit framed bents and joins end to end and form, the fishing net identical shaped with polygonal frame is housed below the framework, pouring weight has been hung in the fishing net lower end, the fishing net lid is equipped with in the fishing net upper end, the end face of each steel unit framed bent is laid steel plate, each framed bent bottom, unit equidistantly is provided with the floating drum that several have a small through hole along indulging each, the floating drum mouth of each floating drum is through flexible pipe, the floating drum valve is connected with a public plastic rigid pipe, with the plastic rigid pipe of steel unit framed bent same root number through separately flexible pipe, be connected with valve separately on the valve connecting plate that float is housed.

Each floating drum two ends is fixed on framed bent bottom, steel unit by steel ring, and last lower steel ring connects together with stainless steel bolt.

Said steel unit framed bent is a tower structure, and there is the steel guardrail framed bent inboard, connects for stainless steel bolt between the steel unit framed bent.

The utility model net cage is compared its superiority with existing similar net cage and is:

1) capacity of anti-storm strong, can avoid red tide, can dive into marine enough degree of depth, be not subjected to the invasion and attack of wind and waves and red tide;

2) simple in structure, easy to assembly, steel structure frame can be made parts separately on the coast, installs buoyancy aid and tracheae, is transported to the assembling of cage culture district;

3) the net cage jacking system all has valve control, and is simple to operate flexible, can finish the sink-float and the adjustable speed of net cage in certain degree of depth;

4) net phase float structure all adopts the standardization material, is easy to buying, and is easy for installation, economical and practical, the suitable popularization;

5) etting of net cage is handled by anti-soil technology, can prevent halobiontic adhering to and influences breed.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

The utility model be by six unit framed bents 2 by the stainless steel bolt hexagonal-shaped frame formula structure that is formed by connecting from beginning to end, fishing net 9 is housed below the hexagonal-shaped frame, pouring weight 10 has been hung in fishing net 9 lower ends, fishing net lid 1 is equipped with in fishing net 9 upper ends.As Fig. 1, Fig. 2, shown in Figure 3, framed bent 2 is by the affixed rectangularity tower structure of steel material, and promptly rectangle upper frame 12 is welded with the connecting rod 15 of rectangle underframe 17 by four jiaos.Be welded with straight-bar 18 as bracing piece between the upper and lower framework of rectangle, be welded with cross bar 14 on the rectangle upper frame.Lay two block plates 3 on the rectangle upper frame 12 of each unit framed bent, there is steel guardrail 11 the framed bent inboard, and guardrail supports with straight-bar 13.

Longitudinally be arranged at intervals with four floating drums 4 in the bottom of framed bent, floating drum is a plastic material, and its two ends are fixed by steel ring 16 usefulness stainless steel bolts, and steel ring is with the welding of framed bent bottom.Floating drum mouth 21 is connected with valve 20 by flexible pipe 22, framed bent four floating drums 4 in unit are connected by floating drum valve 20 and plastic rigid pipe 19 separately, with the plastic rigid pipe 19 of steel unit framed bent 2 identical radicals through separately flexible pipe 5, be connected with valve separately 7 on the valve connecting plate 8 that float 6 is housed.As shown in Figure 4, total six roots of sensation flexible pipe 5 is linked to be and a branch ofly is connected with six valves 7.

The sink-float system works principle of this net cage is: when net cage need sink, open the valve 20 and the float place valve 7 of floating drum, can discharge the air in the floating drum, seawater enters floating drum by advancing (row) water small through hole 12, by net cage deadweight and pouring weight 10, thereby net cage is sunk, but sink to precalculated position valve-off 7, if sinking net cage imbalance can be controlled by control valve 7; When need floating, can in floating drum, inflate by net cage by valve 20 and the float place valve of opening 7, water in the floating drum advances (row) mouthful blind hole 23 by floating drum and discharges, can control net cage frame rising balance by control valve 7 equally, stopping to rise can valve-off 7.
