Aquaculture net cage elevating adjusting device and gravity aquaculture net cage in open sea areas

Abstract

The invention relates to an aquaculture net cage elevating adjusting device and a gravity aquaculture net cage in open sea areas. A water storage floating bin and a water storage sinking bin of the aquaculture net cage elevating adjusting device communicate with each other to form a communicating vessel through a communicating pipe; the water storage floating bin communicates with the water storage sinking bin through a first water pipe and a second water pipe; the first water pipe controls a switch through an electromagnetic valve; a submersible pump is arranged in the water storage sinking bin; and the submersible pump is connected to the second water pipe, and fresh water in the water storage sinking bin can be sent to the water storage floating bin through the submersible pump. Multiple anchor cables of the gravity aquaculture net cage in open sea areas are distributed along the circumferential direction of a net cage body; the gravity aquaculture net cage in open sea areas corresponding to each anchor cable is provided with the aquaculture net cage elevating adjusting device; and the water storage floating bin of each aquaculture net cage elevating adjusting device is arrangedon the corresponding anchor cable, and the water storage sinking bin corresponding to each anchor cable is arranged at the bottom of the net cage body. The gravity aquaculture net cage can ensure thelong-term reliability of elevating adjustment of the gravity aquaculture net cage, and is simple in structure.

Description

technical field [0001] The invention belongs to the technical field of ups and downs adjustment of aquaculture net cages, and in particular relates to a lifting adjustment device for aquaculture net cages and an open sea gravity type aquaculture net cage. Background technique [0002] During the use of the breeding cage, it is necessary to carry out feeding, harvesting and depth adjustment operations. During the above operation, the lifting and sinking control of the breeding cage in the water body will be involved, and the main body of the breeding cage needs to be adjusted by the auxiliary device. . [0003] The gravity cage is one of the common culture cages, and its lifting control is usually adjusted by the cooperation of floats and sinkers. The patent titled "High Density Polyethylene Frame Gravity Type Net Cage Lifting Control Method" (application number CN200910195659.6) discloses a gravity type net cage lifting control method. The bottom of the net cage is provided...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technologies all realize the control of the ups and downs of the cage by injecting seawater (water source of the external environment) into or discharging the inside of the lifting adjustment device. Since the inside of the lifting adjustment device needs to interact with the external environment, organisms and other suspended matter in the seawater It can block the inlet and outlet, and the microorganisms in the seawater can attach to the inside of the lifting adjustment device and the inlet and outlet to grow and reproduce, and eventually lead to poor inlet and outlet

Therefore, the lifting adjustment device disclosed in the above-mentioned prior art will have problems such as inconvenience and inability to adjust the lifting adjustment after a long period of use, and cannot guarantee long-term normal use.
