Description

Large-scale fish culture net cage equipment

Technical Field

The invention belongs to the technical field of aquaculture equipment, and particularly relates to large-scale fish culture net cage equipment.

Background

The net cage culture originated in southeast Asia countries such as Cambodia at the end of 19 th century and then was transmitted to all over the world. In the last 70 th century, cage culture has begun in China, and because of the characteristics of low investment, high yield, mobility, quick response and the like, the cage culture is developed vigorously in lakes and reservoirs all over the country in short decades.

However, the traditional net cage has the problems of fixed installation position, single structure, simple function and low utilization rate.

Disclosure of Invention

The invention aims to solve the technical problem of providing large-scale fish culture net cage equipment which can be moved and positioned and has high utilization rate.

The technical scheme adopted by the invention is as follows: a large-scale fish culture net cage device comprises a large-scale net, a plurality of dynamic positioning culture net cages, a plurality of floaters and a plurality of sinkers; the dynamic positioning aquaculture net cages are used for positioning and supporting the large-scale netting, one side, close to the water surface, of the large-scale netting is connected with the floats, and one side, close to the seabed, of the large-scale netting is connected with the sinkers, so that the shape of the large-scale netting is kept, and the large-scale netting is tensioned.

The invention has the beneficial effects that:

1. compared with the traditional aquaculture net cage, the invention utilizes the characteristic that the dynamic positioning system can actively control the position of the dynamic positioning system, and the dynamic positioning aquaculture net cage is used for carrying out fish culture by depending on a fixed large-scale net clothes while realizing the culture function, thereby obtaining more efficient effect and greatly improving the utilization rate.

2. The dynamic positioning aquaculture net cage can provide necessary assistance for aquaculture activities in the large-scale net, such as stacking of baits, fishing of finished fishes, cleaning of the net and the like. The growth environment in a large water area is closer to the natural environment required by the growth of fishes, and the growth of fish schools is facilitated.

3. The fish activity range is controlled within a depth relatively suitable for the growth of the fishes by prolonging the depth of the large net so as to reduce the loss and environmental pollution caused by the escape of the fishes. The net between the two dynamic positioning aquaculture net cages is tensioned by matching the floater with the sinker, which has simple structure and convenient assembly.

Detailed Description

For a better understanding of the objects, structure and function of the invention, an infusion bag in accordance with the present invention will now be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, the large fish farming net cage of the present invention includes a dynamic positioning farming net cage 5 and a large netting 9.

The dynamic positioning aquaculture net cage 5 can perform the fish aquaculture function and simultaneously position the large netting 9; the large netting 9 is used for enclosing the moving area of the cultured object to avoid the cultured object from escaping; the net hanger 7 and the sinker 11 are used to maintain the shape of the large-sized net. Since the large netting 9 enlarges the culture area, additional auxiliary ships are needed for bait feeding, monitoring and adjusting fish growth and fishing, such as an aquatic product shipping ship, a refrigeration processing ship and an oil tanker, to support the transportation of the fish catch, the supply of fishery production and the like.

Referring to fig. 3, the dynamic positioning aquaculture net cage 5 comprises a dynamic positioning system, a net rack 7, two floating rings 1 and a plurality of lock catches 8; the upper floating ring 1 and the lower floating ring 1 are fixed through net hangers 7, the number of the net hangers 7 is multiple, preferably four, the two floating rings 1 and the plurality of the net hangers 7 are used for fixing net cages 6 to enable the net cages 6 to maintain the shapes, a plurality of lock catches 8 are arranged on one net hanger 7 and can be used for connecting large-scale net cages 9 and dynamic positioning cultivation net cages 5, and underwater robots can be carried on the net hanger 7 for monitoring the growth of fishes; ten dynamic positioning aquaculture net cages 5 are arranged and combined into a decagon shape close to a circle.

The outer side of the floating ring 1 positioned below is provided with a plurality of propellers 4 for positioning, preferably three propellers 4, the operation of the propellers 4 is adjusted to ensure that the aquaculture net cage can be kept at a proper position in the marine environment, and the aquaculture net cage can be used for storing bait and supporting various production and living activities; the propellers 4 are provided at both left and right ends of the floating collar 1 and at the inner end remote from the large net 9. A central control platform 3 is arranged at the center of the dynamic positioning aquaculture net cage 5 and used for controlling the propeller 4 to position the net cage.

The power mechanism of the propeller 4 is a motor and is arranged on the floating ring 1.

A cross sidewalk 2 is fixed in each floating ring 1; the central control platform 3 is arranged in the middle of the cross sidewalk 2 above, the central control platform 3 can be assembled with a navigator and a control system for positioning, and the position of the dynamic positioning aquaculture net cage 5 is adjusted by controlling the operation of the propeller 4 through the computer, so that the large netting 9 is tensioned. The three propellers 4 and the net hanger 7 are equally arranged around the power positioning aquaculture net cage 5.

Referring to fig. 4, a plurality of floats 10 are arranged above the large-sized nets 9, respectively; the lower end of the large-scale netting 9 is fixed by a plurality of small sinkers 11, and a connecting rope 12 is connected with the large-scale netting 9 and the sinkers 11;

the large netting 9 is deeper than the net cage netting 6 of the dynamic positioning aquaculture net cage 5, as shown in fig. 1, the large netting 9 comprises ten identical net sheets which are respectively arranged between the two dynamic positioning aquaculture net cages 5, and the net sheets are fixed by the net racks 7 of the dynamic positioning aquaculture net cages 5 at the left side and the right side. One side of the net piece close to the water surface is connected with a plurality of floaters 10, and one side close to the seabed is connected with a sinker 11 for keeping the shape of the net piece and tensioning the net piece.
