A kind of deep water aquaculture net cage

Abstract

The invention relates to a net cage for deep-water aquaculture, which comprises a net, a floating body ring, a rigid support, a support plate, an underwater acoustic transducer, an electronic warehouse and a release device; the net adopts a cylindrical structure and is arranged at the top periphery of the net There is a floating body ring, and the periphery of the floating body ring is connected to the support plate through a rigid bracket. The rigid support supports the support plate and is located in the middle above the floating body ring; the underwater acoustic transducer is located on the upper part of the support plate, and the electronic warehouse is located on the lower part of the support plate. , the electronic compartment is equipped with a battery, a control system and a motor; the output shaft of the motor in the electronic compartment is connected to the release device, and the release signal received by the underwater acoustic transducer is transmitted to the control system in the electronic compartment, and then controlled by the control system The motor rotates, thereby controlling the action of the release device. The invention has the advantages of simple structure and convenient operation, can effectively avoid the invasion of the net cage by wind and waves, has high breeding safety, can also be operated by remote control, and can be widely used in the field of marine aquaculture.

Description

technical field [0001] The invention relates to an aquaculture net cage, in particular to a deep-water aquaculture net cage applied in the field of mariculture. Background technique [0002] Mariculture is gradually developing from the shallow water area of ​​the inner bay to the open and deep water area. The ability of the cage to withstand wind and waves is an urgent problem to be solved. However, the performance of traditional cages against wind and waves is poor. According to the wave theory that the wave height decays exponentially with the increase of water depth, the cage Settling to a certain depth of water layer underwater is an important technical measure for the cage to resist wind and waves, thus giving birth to the lifting cage. At present, most of the anti-wind and wave lifting net cages use two processes of inflatable drainage and water intake and exhaust to control the lifting, but there are disadvantages such as complicated and time-consuming operation proce...

[0002] Mariculture is gradually developing from the shallow water area of ​​the inner bay to the open and deep water area. The ability of the cage to withstand wind and waves is an urgent problem to be solved. However, the performance of traditional cages against wind and waves is poor. According to the wave theory that the wave height decays exponentially with the increase of water depth, the cage Settling to a certain depth of water layer underwater is an important technical measure for the cage to resist wind and waves, thus giving birth to the lifting cage

At present, most of the anti-wind and wave lifting net cages use two processes of inflatable drainage and water intake and exhaust to control the lifting, but there are disadvantages such as complicated and time-consuming operation process and excessive sinking force of the net cage configuration, and the lifting technology of the net cage is not yet perfect. Mature

General lifting cages usually float above the water surface, and then quickly go deep into deep water when there is a strong wind and wave. There is also a bottom-sinking lifting cage that usually sinks at the bottom, but its structure is complicated, and it is inconvenient to retract and control.
