Deep water culture net cage

Abstract

The invention relates to a deep water culture net cage. The deep water culture net cage comprises netting, a floating ring, a rigid support, a supporting disk, an underwater acoustic transducer, an electronic storehouse and a release device; the netting adopts a cylindrical structure, the floating ring is arranged on the periphery of the top of the netting, the periphery of the floating ring is connected with the supporting disk through the rigid support, and the rigid support puts up the supporting disk to be located in the middle above the floating ring; the underwater acoustic transducer is arranged on the upper portion of the supporting disk, and the electronic storehouse is arranged on the lower portion of the support disk and internally provided with a battery, a control system and a motor; a motor output shaft inside the electronic storehouse is connected with the release device, after the underwater acoustic transducer transmits a received release signal to the control system inside the electronic storehouse, the motor is controlled by the control system to rotate, and then the release device is controlled to act. The deep water culture net cage is simple in structure, convenient to operate and capable of effectively avoiding intrusion of wind waves to the net cage, the culture safety is high, long distance remote operation can be conducted, and the deep water culture net cage can be widely applied in the field of seaculture.

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...
