Abstract

The utility model relates to a sink-and-float controlling fish-breeding net cage, comprising a float with a float rope and a net cage body that comprises a net, a net circle and a net cover. The utility model is characterized in that the utility model also comprises an overall tube with a branch tube which can be integrated with the tube. A sealing clamp is arranged on the upper end of the branch tube which can be fixed or winded on the float rope. When the sealing clamp is taken away the tube can be aerated or vented air. And the float is a controlling float which comprises a float rope and a rope knot or a rope clamp. The utility model solves the problem of controlling the position of the sink-and-float net cage successfully by aerating air into the rubber tube or venting air from the rubber tube to increase or decrease the buoyancy of the net cage system to control the sinking and floating of the net cages. And the net cage can be fixed in the required water level according to the length of the float rope prepared so that the sink-and-float of the net cage can be controlled effectively, and thus the labors and material needed by prior sink-and-float net cages can be reduced greatly.

Description

Controlled heavy formula fish culture net cage

Technical field the utility model relates to a kind of controlled heavy formula fish culture net cage device.

The background technology net cage is thrown in marine, be in severe sea condition all the year round, existing wind wave resistance net cage has sea net cage system, submergeable fish culture net cage, floating type net cage, the sea net cage system is arranged on the sea in open marine site always, the attack that the gentle elasticity of dependence net cage manufactured materials is resisted high sea, whole net cage is influenced greatly by high sea, is not suitable for culturing demersal fishes; The submergeable net cage is placed on the sea in open marine site at ordinary times and carries out breeding production, come temporarily as high sea, just it is sunk under water certain depth to hide the attack of typhoon wave, its production cost height, operating difficulties is an investment that non-common breed owner can bear; The floating type net cage is deposited in certain depth and carries out breeding production, only when needed just the floating water surface of going up of net cage, finishes about again net cage being sunk under water after the operation, this kind net cage is with low cost, capacity of anti-storm is strong and simple in structure, but its operability is relatively poor, and net cage anti-current ability is relatively poor.

The summary of the invention the purpose of this utility model provides a kind of with low cost, easy and simple to handle, wind wave resistance floating type fish culture net cage that the anti-current ability is strong, to overcome the existing existing deficiency of net cage technique.

The utility model is on existing submerging cage basis, include the float of corkline and the net cage main body that etting, net circle and square constitute, it is characterized in that it also comprises the flexible pipe of the outer etting of the outsourcing flexible pipe that has arm that is fixed on the square periphery, ramuscule pipe as flexible pipe, can fix or around being attached on the corkline, there is clips its upper end, only need take off that clips can be filled, exhaust, above-mentioned flexible pipe and arm can be integral, and can be rubbers.After the rubber hose exhaust, when sinking to required water layer, can control the depth of water by the length of corkline.

Description of drawings

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

Fig. 2 is flexible pipe and connection diagram thereof.

Fig. 3 is the Floater Structure schematic diagram.

Wherein: 1. flexible pipe, 2. square, 3. etting, 4. net circle, 5. float, 6. corkline, 7. arm, 8. clips, 9. knot or rope clamp, the 10. outer etting of flexible pipe.

Embodiment

As Fig. 1, the utility model includes the float 5 of corkline 6 and the net cage main body that etting 3, net circle 4 and square 2 constitute, it is characterized in that it also comprises the flexible pipe 1 of the outer etting 10 of the outsourcing flexible pipe that has arm 7 that is fixed on square 2 peripheries, this arm 7 has one or two, daily fix or around being attached on the corkline 6, there is clips 8 these arm 7 upper ends, and it is promptly inflatable only need to take off clips 8, and above-mentioned rubber hose 1 and arm 7 can be integral.

Above-mentioned float 5 is provided with corkline 6 and knot or rope clamp 9, and promptly above-mentioned float 5 is can be by the length of corkline 6 and the control formula float of knot or rope clamp 9 control net cages water layer of living in.

Obviously, the utility model has solved the positional control problem of floating type net cage preferably, it can by dash to flexible pipe, exhaust increases or the buoyancy that reduces net cage system rises net cage or sinking, and can net cage be fixed in required water layer according to the corkline length that fixes in advance, thereby solve floating type net cage operational problem effectively, significantly reduced the required human and material resources of general submerging cage.
