Energy self-supplying type multifunctional deep-sea net cage

Abstract

The invention discloses an energy self-supplying type multifunctional deep-sea net cage, which comprises a net cage (8) positioned in seawater and an anchoring system for connecting the net cage (8) with the seabed and further comprises an ocean energy power generation system, an automatic sedimentation system, an automatic feeding system and a remote monitoring system, wherein the ocean energy power generation system is installed around a frame of the net cage; the automatic sedimentation system is installed on a frame at the upper layer of the net cage (8); the automatic feeding system is installed in the centre on the top of the net cage (8); one terminal of the remote monitoring system is installed on the submarine net cage (8); the other terminal of the remote monitoring system is installed on an shore-side controller; and the two terminals are connected through a GPRS (General Packet Radio Service) network. After adopting the method disclosed by the invention, the energy self-supplying type multifunctional deep-sea net cage is capable of automatically feeding fishes in the net cage, remotely monitoring growth conditions of the fishes and damage conditions of fishing nets, being always the same as ascending and descending of the sea level, and automatically supplying electrical energy required for realizing the above functions.

Description

technical field [0001] The invention relates to the technical field of deep-sea aquaculture, in particular to an energy self-supply multifunctional deep-sea net cage. Background technique [0002] my country's ocean energy resources are very rich, and islands and surrounding areas are rich in renewable ocean energy resources, such as tidal current energy and wave energy. Tidal current energy is the kinetic energy formed when the tidal force of the moon and the sun causes the seawater to produce periodic reciprocating horizontal motion, concentrated in the waterways or bays between the shore and islands, and the tidal current energy power generation directly uses the water flow of the ebb and flow to impact the impeller and other mechanical devices to generate electricity. In addition, in recent years, the global mariculture technology has developed rapidly, especially the cage culture in nearshore waters or open seas has played an important role, which is customarily called...

Problems solved by technology

[0004] 1) Because in the breeding process, maintaining the normal operation of the entire culture cage requires electric energy, and the deep-sea cage is located in the offshore sea area, it is unrealistic to pull the cable from the shore to provide the power supply of the deep-sea cage , On the one hand, it is difficult to install, on the other hand, the cost is also high;

[0005] 2) During the breeding process, it is necessary to regularly feed the fish in the cages, usually by artificial feeding, that is, the farmers regularly go to the sea to the vicinity of the cages to feed the fish in the cages , but this artificial feeding method is greatly restricted by the sea conditions, and it is not possible to go to sea for feeding normally when encountering stormy days, which is not conducive to the normal growth of fish, thus affecting the yield and quality of aquaculture;

[0006] 3) In the process of fish farming, because the net cages are hidden deep in the sea water, the farmers cannot know the growth of the fish on the shore, nor can they know whether the fishing nets on the net cages are damaged;

[0007] 4) Due to the changeable sea surface conditions, the sea level rises and falls, and the net cage will fluctuate and tilt with the sea water. Therefore, it will affect the activities of fish in the net cage, and will also affect the yield and quality of culture.
