Deepwater aquaculture net cage using wave energy

Abstract

The invention discloses a deepwater aquaculture net cage using wave energy. The deepwater aquaculture net cage using the wave energy comprises a net cage (4), an anchor chain (2) and a foundation pillar (1). One end of the anchor chain (2) is connected with the net cage (3), the other end of the anchor chain (2) is connected with the foundation pillar (1), and the foundation pillar (1) is fixedly installed on the seabed. The deepwater aquaculture net cage using the wave energy further comprises an automatic feeding system, an automatic subsiding system, a remote monitoring system and an ocean power generation system using wave energy. The ocean power generation system is installed on the periphery of the frame of the net cage, the automatic subsiding system is installed on the upper layer frame of the net cage (4), the automatic feeding system is installed on the middle portion of the top portion of the net cage (4), one terminal of the remote monitoring system is installed on the net cage (4) under water, the other terminal is installed on a controller on shore, and two terminals are connected through a general packet radio service (GPRS) network. And therefore, the electric energy generated through the wave energy supplies energy needed by each system in a deepwater cage aquaculture process.

Description

technical field [0001] The invention relates to the technical field of deep-sea aquaculture, in particular to a net cage for deep-sea aquaculture utilizing wave energy. Background technique [0002] my country's ocean energy resources are very rich, and the islands and surrounding areas are rich in renewable ocean energy resources. However, with the development of the economy and the continuous improvement of people's living standards, the demand for marine aquatic resources continues to increase. Overfishing in the ocean has led to a serious decline in natural fishery resources. It is impossible for fishing operations to guarantee the sustainable development of our marine fisheries. [0003] In order to solve the above contradictions, the fishery production mode has shifted from mainly fishing to artificial cage culture. And the ability of existing net cage to resist wind and waves is relatively poor, can only be concentrated in part shallow water sea area, inner bay etc. ...

AI Technical Summary

Problems solved by technology

[0004] 1) Since automatic control functions such as fish feeding, water quality monitoring and net cleaning are to be realized during the breeding process, electric energy is required to maintain the normal operation of the entire breeding cage. The power supply of the existing outlying island cages is mainly through the island diesel engine Power generation, and then the cables transmit electric energy to the cages to ensure the power supply of the cage facilities, but for the open sea area far away from the island, this power supply method is obviously not realistic;

[0005] 2) In addition, the weather environment on the sea surface is changeable, and in the typhoon season, the net cage is easy to overturn, which requires the deep water net cage to have the function of diving to avoid the typhoon, and the net cage of the prior art has poor wind and wave resistance and is easy to overturn;

[0006] 3) In the open sea area, the wind and waves are relatively large, which can easily cause the loss of the effective volume of the cage, and the excessive wind and waves are not suitable for the growth of cultured fish;

[0007] 4) In deep water areas, marine attachments such as seaweed and shellfish are easily attached to the nets, which increases the resistance of the cages, causes the deformation of the cages, and reduces the effective breeding volume. In order to remove the attachments on the nets, now There are a variety of net cleaning mechanisms in the technology, such as high-pressure water guns, automatic net washing machines, etc., but most of them are manually operated or driven by motors, which are cumbersome
