Sinking and floating type net cage

Abstract

The invention relates to a sinking and floating type net cage. The sinking and floating type net cage comprises at least two floating pipes, multiple floating pipe connection pieces, multiple handrails, at least one set of net, at least one net base rack, at least one sinker, at least one wire collector, at least one anchor, multiple sets of chains or ropes and at least one pipe-in-pipe. The floating pipes are used as floating bodies of the sinking and floating type net cage and are enclosed into two circles. The floating pipe connection pieces are used for fixing the floating pipes together. The handrails are arranged on the floating pipe connection pieces in an inward manner. The at least one sinker is arranged under the net base racks. The wire collectors are arranged between the net base racks and the sinkers. The anchors are arranged at the bottom of the sea and are used for fixing the net cage so that the net cage will not move along with the water flows. The chains or the ropes are used for connecting the floating pipe connection pieces to the net base racks, connecting the net base racks to the wire collectors, connecting the wire collectors to the sinkers and connecting the sinkers to the anchors. The pipe-in-pipes are sealed and filled with gas and arranged in the floating pipes. Adjusting assemblies are arranged on the floating pipes and / or the wire collectors, and are used for adjusting the sinking and floating of the net cage.

Description

technical field [0001] The invention relates to a sinking-floating net cage, which is mainly used for raising fish in water and belongs to the field of plastic sinking-floating net cages. Background technique [0002] China is the world's largest aquaculture country. There are many types of aquaculture and high density. Most of them are cultured with fishing rafts in offshore harbors. In recent years, the harbors have been unable to withstand such high-density aquaculture. Moreover, the exchange of aquaculture water in the harbor is poor, and fish are prone to disease. The abuse of drugs by farmers in order to protect their investment further exacerbates the deterioration of water quality. In 2015, the state promulgated the "Water Ten Measures", which made clear requirements for fish raft farming, gradually removed and replaced, and encouraged fishermen to use deep-water cages to raise fish. Whether it is fish farming in fishing rafts or fish farming in deep-water cages, th...
