Netting and net cage system used for mariculture

Abstract

The invention discloses a netting and net cage system used for mariculture. The netting and net cage system used for mariculture comprises a net cage (1), a plurality of nettings (2), a hoisting device (3) and a plurality of decontamination plates (4), wherein the net cage (1) comprises aisle plates (5) and floating pipes (6); the aisle plates (5) and floating pipes (6) are connected through a connecting plate (7); the floating pipes (6) form a plurality of grids; the bottom parts of the grids are connected with the nettings (2); a guide rail (8) is processed on the top of each aisle plate (5); the hoisting device (3) comprises a bracket, an elevator (9) and a netting supporting frame (10), wherein the elevator (9) is connected with the bracket and the netting supporting frame (10); the bracket is provided with a plurality of universal wheels (11), and the universal wheels (11) are placed in the guide rails (8); and each decontamination plate (4) comprises a scraping plate (12) and a vane (13), wherein the scraping plates (12) and the floating pipes (6) are connected. The netting and net cage system disclosed by the invention can reduce seawater wave force, is convenient in fishing, has a long service life and can prevent alga or shellfish marine organisms from growing on the floating pipes.

Description

technical field [0001] The invention belongs to the technical field of agricultural science and aquatic products, and in particular relates to a net cage system for marine cultivation. Background technique [0002] Net cages are an important tool for marine farming at present. Net cages float on the sea and are used to breed marine organisms under seawater conditions. They generally consist of four parts: cages, nets, fixed parts and accessories. The net material is mainly synthetic fiber or copper alloy. Compared with synthetic fibers, copper alloy netting will not grow algae, so that the seawater in the breeding area has good fluidity, and can provide a suitable water environment for the growth of marine organisms. However, due to the high density of the copper alloy, the entire netting is heavy, which will eventually bring about two problems: one is that under the action of seawater waves, the heavier copper alloy netting makes the connection between the net cage and the...

AI Technical Summary

Problems solved by technology

However, due to the high density of the copper alloy, the entire netting is heavy, which will eventually bring about two problems: one is that under the action of seawater waves, the heavier copper alloy netting makes the connection between the net cage and the net cage bear a very large load. The connection part is easy to be damaged due to excessive force; the second is that the net needs to be pulled out of the water when fishing, and the heavy net is not convenient for manual operation

The floating tube will grow algae or shellfish, which will cause corrosion to the floating tube and reduce the life of the floating tube
