Description

A deep water cage

                      

The utility model relates to an aquaculture cage.

Background technique

Most of the current net cages have poor wind and wave resistance, so they can only be set in the inner bay and near-shore shallow seas, and the aquaculture waters are limited. As a result, the scale of seawater cage aquaculture in some areas exceeds the aquaculture capacity of the bay. On the one hand, it makes It is difficult to expand the scale of production. On the other hand, it causes the deterioration of the breeding environment and affects the growth of fish and the ecological environment. The development of deep-sea culture cages that can resist wind and waves is the direction of cage aquaculture.

Contents of the invention

The technical problem to be solved by the utility model is to provide a deep-water cage capable of resisting wind and waves.

Due to the adoption of the above technical scheme, the utility model is a net cage very suitable for deep sea survival and operation. Its posture is stable in the sea, and it is not easy to cause local drift and deformation of the net cage due to the influence of ocean currents and wind waves; the setting of the working platform is convenient for operation; the setting of the skeleton rope can not only make the structure stronger but also facilitate the replacement of fishing nets; the utility model has adjustable buoyancy, The sinker can be raised to raise the fishing net for fishing, and the utility model can be dived to avoid wind and waves when the wind and waves are very large.

The utility model can also adopt the following further technical solutions simultaneously:

The buoyancy of the floating body of the working platform is adjustable. This is beneficial to the buoyancy adjustment of the utility model.

The adjustable buoyancy of the floating body of the working platform means that the working platform is formed by connecting several air tanks, and the air tanks are provided with ballast water tanks that can be filled and drained. Alternatively, the adjustable buoyancy of the floating body of the working platform means that the working platform is formed by connecting several air chambers and ballast water chambers that can be filled and drained. In this way, the working platform can be assembled on site, which facilitates the transportation of the working platform.

The sinker with adjustable buoyancy means that the sinker is equipped with a ballast water tank that can be filled and drained, and the ballast water tank is formed by connecting several sub-ballast water tanks. In this way, the sinker can also be assembled on site, which facilitates the transportation of the sinker.

The outer wall of the working platform is provided with concave ribs along the circumference. In this way, the external force resistance of the working platform can be increased, and the bolts for assembling the working platform can be placed in the ribs without exposing the surface of the working platform, so that the phenomenon of bolt hooking will not occur.

The ballast weight block is arranged on the top of the ballast water tank, the side wall of the ballast water tank is provided with concave pressure ribs along the circumference, and the bottom is provided with supporting feet. In this way, the anti-external force capability of the ballast water tank can be increased, and the bolts of the ballast water tank can be placed in the ribs without exposing the surface of the working platform, so that the phenomenon of bolt hooking will not occur. Lifting when the utility model touches the seabed.

It also has a safety rope for the sinker, and one end of the safety rope is connected to the sinker and the other end is connected to the working platform.

Detailed ways

Refer to attached picture. The utility model comprises a working platform floating body 1, a buoyancy ring 2, a sinker 4 with adjustable buoyancy and a weight block 3, the area surrounded by the buoyancy ring is larger than the area of the working platform, and the working platform is provided with a working port 5. Platform and buoyancy ring and buoyancy ring and sinker are connected with framework rope 6 and line rope 7, and fishing net 8 is connected with line rope.

The buoyancy of the floating body of the working platform may be adjustable.

The adjustable buoyancy of the floating body of the working platform means that the working platform is formed by connecting several air tanks 9, and the air tanks are provided with ballast water tanks 10 which can be filled and drained. The ballast water tank can also be independent from the air tank, so that the working platform is formed by combining the air tank and the ballast water tank.

The aforementioned sinker with adjustable buoyancy means that the sinker is provided with a ballast water tank 11 that can be filled and drained, and the ballast water tank is formed by connecting several sub-ballast water tanks 12 .

The outer wall of the working platform is provided with concave pressure ribs 13 along the circumference. In this way, the connecting bolts 16 of the working platform are in the ribs and are not exposed.

The ballast weight block is arranged on the ballast water tank 11 , the side wall of the ballast water tank is provided with a concave bead 14 along the circumference, and the bottom is provided with a leg 15 . In this way, the connecting bolts 17 of the sub-ballast tanks 12 are inside the bead and are not exposed.

The utility model can also be provided with the safety rope 17 of sinker, and one end of safety rope is connected with sinker, and one end is connected with working platform. Reference numeral 23 is the eye plate and the shackle of the safety rope. Reference numeral 24 is the retractable device of safety rope. Reference numeral 25 is the limit ring of safety rope. The safety rope can play outside the insurance effect to the sinker once the skeleton rope breaks, and is also beneficial to prevent the sinker from drifting and lifting the sinker or assisting the effect.
