Movable navigating net cage device capable of protecting marine environment

Abstract

The invention discloses a movable navigating net cage device capable of protecting the marine environment, which comprises an upper float, pin mechanisms, shifting navigating propeller mechanisms, a deep-sea base, net cage floating guide piles, anchor chains and anchors. In terms of connection, the upper end of each net cage floating guide pile is connected with the upper float through one pin mechanism, and the lower end of each net cage floating guide pile is fixed to the deep-sea base. By means of the movable navigating net cage device, the problem that current marine environmental pollution by net cages is solved effectively, a net cage can be regularly and flexibly shifted to cultivation, pollution of culture waters is avoided, and disease outbreak, disease spread or large-scale sudden death of culture objects is avoided. The movable navigating net cage device is simple in operation, safe and reliable. The culture net cage can be regularly and flexibly moved to keep fine environment of the culture waters and promote sustainable development of aquaculture, and the movable navigating net cage device has high industrial popularization and application value.

Description

technical field [0001] The patent of the present invention relates to a displaceable sailing net cage device with the function of protecting the marine environment, which belongs to the field of machinery. Background technique [0002] In the process of sea cage culture, due to the small wind and waves near the shore and the slow water flow, it is especially suitable for cage culture. Therefore, the density of the cages is often too high, exceeding the normal capacity of the sea area where the culture is located, which brings serious problems. Adverse consequences: First, the marine environment is seriously polluted. Due to poor water flow and slow exchange of marine substances, uneaten bait in the cages and some excrement of the fish themselves are deposited on the seabed for a long time. It has even become a "barren land", where seaweed and other organisms cannot survive; second, when a large-scale epidemic occurs, fish in net cages that are not infected with the disease c...
