Balance submerged culture net cage with double buoyancy vertical pipes

Abstract

The invention provides a balance submerged culture net cage with double buoyancy vertical pipes, relating to marine culture net cages. The net cage comprises buoyancy vertical pipes, buoyancy horizontal pipes, pipe caps, bottom anchors, bottom inner tie bar frames, inflation / exhaust pipes, balance submerging devices and a net, and is characterized in that two buoyancy vertical pipes are arranged at each top corner of each net cage frame; a ladder-shaped side frame formed by connecting the buoyancy vertical pipes and the buoyancy horizontal pipes is arranged on each side of the net cage frame; inner cavities of pipes of the ladder-shaped side frame are communicated with each other; double buoyancy vertical pipes share one pipe cap and one bottom anchor connecting disc; each balance submerging device comprises a submerging sub-control device and a submerging single control device; the submerging sub-control device is arranged at the top of each buoyancy vertical pipe; the submerging single control device is arranged at the bottom of each buoyancy vertical pipe; the submerging sub-control device comprises an inflation floating balancer and a pressure relief submerging balancer. The net cage has the beneficial effects that by adopting the novel double buoyancy vertical pipes and the ladder-shaped side frames, the net cage has high buoyancy and high strength; the new balance submerging devices adopting the submerging sub-control devices enable balance submerging to be more stable and reliable and avoid net cage tipping accidents in submerging processes.

Description

Technical field: [0001] The invention relates to a mariculture net cage, in particular to a double buoyancy riser balance submersible floating culture net cage. Background technique: [0002] The existing submersible aquaculture cage is composed of a buoyancy riser connected with a horizontal connecting pipe. It is a regular polygon when viewed from the top. Since only the buoyancy riser generates buoyancy, the buoyancy of the cage is low when it is raised, only the top of the cage. It can be exposed to the water surface, which is not convenient for the maintenance and management of net cages on weekdays, and it is not convenient for harvesting during the harvest period. [0003] A newly disclosed high buoyancy cage is to change the horizontal connecting pipe to a buoyant buoyant horizontal pipe. It divides the original horizontal connecting pipe into two sections, and welds the open end of one of the buoyant horizontal pipes to the buoyancy riser. The closed end of the buoyancy h...

Problems solved by technology

[0004] Another disadvantage of the above two kinds of submersible floating net cages is that the balance submersible device installed in the buoyancy riser, the air-water control devices at the top of the tube and the bottom of the tube are all air-water single control devices, and the submersible The balance control ability of the process is poor, and there is a possibility of the cage tipping over. Once a cage tipping accident occurs during the diving and floating process, it will cause large economic losses to the farmers.
