Problems solved by technology

[0004] The existing circular lifting cages are single-layer structures, and the cultured products are greatly affected by the seawater conditions in the depth direction, the utilization rate of seawater is low, and the cultured species is single; the lifting is slow and easy to tilt; the utilization rate of bait is low; it is inconvenient to collect fish

Embodiment 1

[0020] Such as figure 1 As shown, the present invention discloses a layered electric lifting three-dimensional ecological net cage for deep water aquaculture, which includes an annular frame 1, a sealing net 2, a bottom ring 3, a local reinforcement component 4, a support ring buckle component, a lifting buoy Ball 7, wherein the support ring buckle assembly includes a support ring 5 and a hook chain 6.

[0021] Each floor of the ecological net cage is composed of double-row ring frames 1, wherein the cage frames of the first layer are distributed in double rows horizontally, the cage frames of the second and third layers are distributed in double rows vertically, and the ring frame 1 and the bottom ring 3 are jointly supported The sealing net 2 constitutes an independent and closed breeding space. The local reinforcement component 4 is nested on the four quarter points of the ring frame 1. The support ring buckle component is arranged on the local reinforcement group 4, and th...

Abstract

The invention relates to the field of aquaculture and discloses a layered electric lifting stereoscopic ecological net cage for deep water culture. The layered electric lifting stereoscopic ecological net cage comprises annular frames, sealing nets, bottom rings, supporting buckle assemblies and lift floating balls. Multi-layer stereoscopic ecological culture is adopted, fishes of different varieties can be cultured, manure of the fishes on the upper layer and remaining bait are diffused to the lower layer through the life habits of the different fishes, bait is saved, the utilization rate of the bait is increased, and benefits are increased. The ecological net cage which is reasonably designed can be matched with an advanced bait putting and monitoring device, the net cage is independently installed in deep water with good water quality, paralic environment pollution is avoided, the seawater plane space is saved, and the utilization rate of seawater is increased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a layered electric lifting three-dimensional ecological net cage for deep water aquaculture. Background technique [0002] Existing marine culture net cage mainly contains three kinds of floating type, sinking type, lifting type. Deep water net cages are required to have anti-wind and wave performance, but also to consider the convenience of management and operation, so lift-type net cages are generally used. At present, the main lifting cages in the world include the marine Sparta butterfly cages in the United States, the Muhai type cages in Sweden, and the round lifting cages in Norway. [0003] The circular lifting cage developed by Norway is currently the most widely used deep-water aquaculture cage. It is mainly composed of frame, net, sinker and mooring system. The frame of the net cage is made of multi-circle, hollow, and fully enclosed high-density polyethylene pipes connect...
