Abstract

The utility model relates to a pulling type lifting breeding net cage device, which is based on the prior settleable type net cage, and comprises a net cage body which consists of a net hoop, a bottom border of the net cage and an anchoring system. The utility model is characterized in that the utility model also comprises an ordinary underwater windlass which is fixed in the seabed with cordage or shrinking ropes and an underwater cable; the other end of the cordage is connected with the bottom border of the net cage body through a dead wire, the connection terminal of the other end of the underwater cable is arranged in the water surface or circled and attached with a floater. When the heavy weather comes, the net cage is sunk down into the underwater, and fixed in the security aqueous layer, behind the heavy weather, the net cage rises to the water surface, the operation is easy and the current management is convenient, thereby effectively solving the operational problems of the floating type net cage and greatly reducing the labor power and the material resources needed by the ecumenical floating type net cage, and the dead wire is equably distributed in the bottom border of the net cage, thereby making the ascending and falling of the net cage receive strength evenly.

Description

Winding type lifting fish culture net cage device

Technical field

The utility model relates to a kind of winding type lifting fish culture net cage device.

Background technology

Net cage is thrown in marine, is in severe sea condition all the year round, and 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, and whole net cage is influenced greatly by high sea, thereby very high to the requirement of net cage system; The submergeable net cage is placed on the sea in open marine site at ordinary times and carries out breeding production, come interim as high sea, just it is sunk under water certain depth to hide the attack of high sea, its production cost height, operating difficulties, it is an investment that non-common breed owner can bear, in addition because it is by to net cage tubing is annotated, net cage is finished in draining rising and decline, the then discharging uniformly simultaneously of the seawater in the net cage tubing, this will cause the tubing unbalance stress, make net cage frame produce distortion greatly, thereby influence its service life; 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, is not easy to daily management.

Summary of the invention

The purpose of this utility model provides a kind of with low cost, simple to operate, and the wind wave resistance winding type lifting fish culture net cage device of convenient management, long service life is to overcome the existing existing deficiency of net cage device.

The utility model is on existing submergeable net cage basis, comprise the net cage main body that net circle, net cage underframe and mooring system constitute, it is characterized in that it also comprises the common winch under water that has rope or flexible rope and submerged cable that is fixed on the seabed, the other end of above-mentioned rope is connected on the underframe of net cage main body by antilift wire, the binding post of the above-mentioned submerged cable other end is positioned on the water surface or around being attached on the float, its binding post seals..

Description of drawings

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

Wherein: 1. mooring system, 2. net circle, 3. net cage main body, 4. underframe, 5. antilift wire, 6. rope, 7. winch, 8. submerged cable under water.

Embodiment

As Fig. 1, the utility model comprises the net cage main body 3 that net circle 2, net cage underframe 4 and mooring system 1 constitute, it is characterized in that it also comprises the winch under water 7 that has rope 6 and submerged cable 8 that is fixed on the seabed, the other end of above-mentioned rope 6 is connected on the underframe 4 of net cage main body 3 by antilift wire 5, the other end of above-mentioned submerged cable 8 is positioned on the water surface or around being attached on the float, its binding post sealing (figure omits) is so that connect ship.High sea comes interim, only needs to start winch 7 under water by the ship electricity, and the length that changes rope 6 can make net cage be in safe water layer.

Obviously, the utility model has solved the positional control problem of net cage for sea farming preferably, it changes the length of flexible rope by submersible machine, control net cage rising or sinking, come net cage to be sunk under the water at high sea temporarily, be fixed in safe water layer, stormy waves can emerge net cage later, simple to operate, daily management is convenient, thereby solves floating type net cage operational problem effectively, has significantly reduced the required manpower of general submerging cage, material resources, and because antilift wire is uniformly distributed in the net cage underframe, make the rising of net cage and sink stressed evenly, thereby prevent the distortion of net cage frame, increase its service life.

Claims

1, a kind of winding type lifting fish culture net cage device, comprise the net cage main body (3) that net circle (2), net cage underframe (4) and mooring system (1) constitute, it is characterized in that it also comprises the winch under water (7) that has rope (6) and submerged cable (8) that is fixed on the seabed, the other end of above-mentioned rope (6) is connected on the underframe (4) of net cage main body (3) by antilift wire (5).
