Problems solved by technology

[0004] However, the body of a marine aquaculture system proposed in this comparative document cannot adjust the overall buoyancy, so it can only float on the sea surface. When the wind force on the sea surface is strong, it is easy to tilt, and the ability to resist wind and waves is not strong

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0031] Embodiments of the present invention provide a deep sea culture fish cage device with adjustable buoyancy, such as Figure 1-8 As shown, there are two buoyant tanks 1, two buoyant tanks 1, a fish cage body between the two buoyant tanks 1, and a buoyancy control mechanism on the fish cage body.

[0032] The fish cage body includes a connecting rod 8, a frame member 5, and a main shaft 7. The main shaft 7 is set to two, and the two main shafts 7 are respectively connected with two buoyancy tanks 1, and the axes of the two main shafts 7 coincide, and the frame member 5 It is set as a hollow rectangular frame, and there are multiple frame-shaped members 5, and the multiple frame-shaped members 5 are equiangularly distributed with the main axis 7 as the center, and both side...

Abstract

The invention provides a fish cage device for deep-sea culture with adjustable buoyancy, which relates to the field of marine culture equipment, and includes a buoyancy tank. The body is provided with a buoyancy control mechanism. When the buoyancy-adjustable deep-sea culture fish cage device needs to sink below the sea surface, by opening the first electromagnet assembly and the second electromagnet assembly, and the first electromagnet assembly and the second electromagnet assembly are facing the side of the buoy. The magnetic pole is the same as that of the permanent magnet facing the first electromagnet assembly and the second electromagnet assembly. At this time, under the repulsion of the same pole, the permanent magnet will be subjected to a repulsion inward, so that the permanent magnet drives the piston plate to push inward , so that the sea water enters the buoy, at this time the buoyancy provided by the buoy decreases, and the whole device will move down until it hovers a certain distance below the sea surface, at this time it can avoid the wind on the sea surface, thereby protecting the entire fish cage, very easy to use convenient.

Description

technical field [0001] The invention relates to the technical field of marine aquaculture equipment, in particular to a deep-sea aquaculture fish cage device with adjustable buoyancy. Background technique [0002] Due to the severe decline of traditional fishery resources, marine fishing has shifted from traditional development to conservation and management, and gradually transitioned to deep-sea aquaculture. Deep-sea cage culture technology is of great significance to expand the culture of sea city, reduce environmental pressure, protect and adjust the structure of marine cultured species. [0003] According to the Chinese patent No. 201620498660.1, a marine aquaculture system is proposed, which includes a body surrounded by a closed structure, a bracket is arranged inside the body, a fishing net is arranged on the bracket, and the body includes an inner surrounding pipe, an outer surrounding pipe and several intervals. On the fixed base for fixing the two, the body is pr...
