Marine ranching device used in deep sea culture area

Abstract

The invention relates to the field of deep sea culture, in particular to a marine ranching device used in a deep sea culture area. The marine ranching device used in the deep sea culture area comprises a rectangular floating block, gauge piles are welded to the four corners on the bottom of the floating block, the tail ends of the gauge piles are fixedly connected with anchor blocks, a cage is arranged among the gauge piles, and screw rods are arranged in the gauge piles. Motors are fixedly connected with the tops of the gauge piles, the motors are located in the floating blocks, the screw rods are connected with the motors, a fixing frame is arranged between every two adjacent gauge piles, the fixing frames are arranged outside the cage and make no contact with the cage, a plurality of fixing blocks are welded to the fixing frame, bearings sleeve the fixing blocks, rotary shafts are connected with inner rings of the bearings, and a plurality of arc-shaped plates are arranged on the rotary shafts. By means of the marine ranching device, the problems in the prior art are solved that the cage volume loss rate is high, the breeding efficiency is low and the breeding environment is poor.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture, in particular to a marine pasture device for deep-sea aquaculture areas. Background technique [0002] Driven by the social economy and the development of the tourism industry, my country's recreational fishery has developed rapidly. Whether it is from the perspective of economic or social benefits, it has good development prospects and great development potential. Therefore, recreational fishery has a broad space for development. Potential guide, actively guide tourists to participate in recreational fishing activities. Moreover, with the large amount of fishing in the offshore area, the number of fish in the offshore area has decreased greatly, and deep-sea aquaculture is particularly important. At present, the area of ​​mariculture in my country is about 30 million mu, accounting for only about 15% of the usable area of ​​shallow tidal flats. The utilization space and potential of tidal flat...

AI Technical Summary

Problems solved by technology

There are two main reasons for this: 1) The marine ranching equipment currently operating mainly in shallow seas is difficult to adapt to the harsh environmental conditions of the deep sea; 2) The deep-sea marine ranching equipment has not yet solved its energy supply problem well

However, due to the fast current flow and unpredictable direction in the deep sea area, the volume loss rate of the cage is very high, the breeding space is reduced, and the life of the cage is not high, resulting in low breeding efficiency and increased breeding costs.
