Self-powered sinking bottom net cage

Abstract

The invention discloses a self-powered submersible net cage which comprises a submersible net cage body with a rigid main frame. A floating frame in the shape of a prismatic table is connected at the upper portion of the main frame. A sealed mesh is connected onto the inner side of the submersible net cage body. A traction cable is connected onto the lower side of the rigid frame and a self-submersion base, and the self-submersion base is provided with a winding-unwinding control assembly. The winding-unwinding control assembly can wind and unwind the traction cable as required so as to control the distance between the self-submersion base and the rigid main frame. The submersible net cage body is connected with a transducer which can convert wave energy to electricity, supply electricity to the winding-unwinding control assembly and store electricity. The winding-unwinding control assembly controls the distance between the self-submersion base and the rigid main frame by winding and unwinding the traction rope, and therefore harvesting and stocking of marketable fishes according to demands are achieved. The transducer generates electricity and store the electricity in the winding-unwinding control assembly. Therefore, the self-powered submersible net cage has the advantages of needing no counterweight system, being convenient to manage, small in energy consumption, good in storm resistance, constant in aquatic water capacity and applicable to middle and lower layer fish breeding.

Description

technical field [0001] The invention relates to an energy-saving rigid bottom-sinking deep-water net cage, in particular to a self-powered bottom-sinking net cage. Background technique [0002] The breeding cage is composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. Wherein the mooring system is the foundation of the cage in the water, once the mooring fixing system has problems in windy and wave weather, it will cause the whole cage to be damaged due to uneven stress. At present, there are three common cage mooring forms at home and abroad: one is the traditional multi-point mooring; the other is the surface grid mooring; the third is the underwater grid mooring. The traditional multi-point mooring system is simple in form. At present, this method is mostly used in coastal floating deep-water cages in my country. In multi-point mooring, there are three types of anchors according to different sea areas. One is pi...
