Technical Field

The invention relates to the technical field of intelligent fisheries, in particular to a flow blocking device for deep-sea intelligent fishery culture.

Background

Under the condition that aquatic animal protein widely enters the dining table of Chinese people, the aquatic product supply in China is mainly breeding; inland and coastal waters have limited space and are limited by environmental protection and the like, aquatic product cultivation must move to deep open sea areas, and deep open sea cultivation is an important way for solving the increasing aquatic product requirements of China. The deep sea water areas far away from the continents have excellent environmental conditions for developing aquaculture, including high-quality water sources, proper regional or ocean-current water temperatures and far away from land-source pollution and diseases, and safe and reliable facility equipment is the key for development.

At present, no facility for adjusting the water flow state in a fishing ground exists in deep and open sea culture, and water flows are naturally exchanged; when the tide is calm, the flow rate in the fishing ground is low, and the cultured fishes grow normally; when the tide or the wave weather rises and falls, the water flow in the fishing ground is large, the cultured fishes consume more energy to resist the water flow, the growth speed is influenced, and partial fish schools are damaged due to too large water flow or die due to insufficient dissolved oxygen in local areas caused by overcrowding. The ocean current direction in deep sea is subject to more uncertain factors, so that the ocean current direction cannot be judged frequently, and the fixed flow blocking mode cannot form effective ocean current blocking.
