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.

Abstract

The invention relates to a raising and lowering adjustment device for aquaculture net cage and its open sea gravity type aquaculture net cage. The water storage floating bin and the water storage sinking bin of the raising and lowering adjustment device for aquaculture net cage are connected through a connecting pipe to form a connector, and the water storage floating bin and The water storage tank is communicated with the second water tube through the first water pipe. The first water tube is controlled by a solenoid valve. A submersible pump is arranged in the water storage tank. The submersible pump is connected to the second water tube and can transfer the water storage tank to The fresh water in the tank is pumped to the water storage floating tank. A number of mooring cables of the gravity-type aquaculture cages in the open sea are distributed along the circumferential direction of the cage body. The gravity-type aquaculture cages in the open sea are equipped with lifting and adjusting devices for each mooring cable. The warehouse is arranged on the mooring cable, and the water storage sinker is arranged on the bottom of the net cage body corresponding to each anchoring cable. The invention ensures the long-term reliability of the raising and lowering adjustment of the culture net cage, and has a simple 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...
