A breeding water tank for a mobile farming vessel

Abstract

The invention relates to an aquaculture water chamber used for a movable aquaculture factory ship. The aquaculture water chamber comprises a fish farming water chamber body, and the fish farming water chamber body is internally provided with water obtaining traps which pump deep and far sea water to convey the sea water into the fish farming water chamber body; a center line bulkhead is arranged in the middle of the fish farming water chamber body and divides the fish farming water chamber body into two independent chambers including the left chamber and the right chamber; overflow pipes are arranged at the bottom of the fish farming water chamber body and provided with butterfly valves, and the overflow pipes are connected to the positions above designed drafts of sides along the side walls of the fish farming water chamber body; by opening the control butterfly valves of the overflow pipes, water continuously overflows from the bottom of the water chamber to the outside of ship boards to achieve water flow exchange. The water chamber can meet the requirements ofwater flow exchange and dirt discharge of large chamber aquaculture.

Description

technical field [0001] The invention relates to the technical fields of ship engineering and aquaculture, in particular to an aquaculture water tank used for a mobile aquaculture vessel. Background technique [0002] my country is one of the countries with developed aquaculture in the world, and its aquaculture area and total output both rank first in the world. Statistics from the World Food and Agriculture Organization (FAO) show that the total output of my country's mariculture industry was only 100,000 tons in 1955, and has increased year by year since then. It has developed rapidly in the past 30 years. It exceeded 3 million tons in 1990 and rose to 13.4 million tons in 2008, accounting for 51.6% of domestic marine aquatic product production and about 2 / 3 of the world's total marine aquaculture production. Aquatic products can provide human beings with rich protein. In modern times where land resources are increasingly scarce, the importance of aquatic products continu...

Problems solved by technology

In the 1980s, developed countries also put forward the concept of developing large-scale farming ships, but due to the lack of industrial development conditions, the main industry has not been formed.
