Method for manufacturing low-carbon type jellyfish fence device

Abstract

The invention provides a method for manufacturing a low-carbon type jellyfish fence device. The method adopts bamboo rods, a copper-alloy oblique and square net, high-strength polyethylene monofilaments, ultra-high molecular weight polyethylene net wires and a twelve-strand dacron rope, and is characterized in that high-strength polyethylene monofilament ropes are manufactured by using the high-strength polyethylene monofilaments; the exteriors of the bamboo rods are sheathed with plastic-coated waterproof canvas sleeves; the canvas-sheathed bamboo rods are installed on each side of a jellyfish pool; the high-strength polyethylene monofilament ropes are installed as perpendicular lacing lines in the length direction of the copper-alloy oblique and square net, and two net ends are connected in an equal mesh way by a copper wire with 1mm wire diameter; one high-strength polyethylene monofilament rope is installed on each of the upper edge and the lower edge of the copper-alloy oblique and square net as an upper lacing line and a lower lacing line; the copper-alloy oblique and square net is perpendicularly assembled on the peripheral canvas-sheathed bamboo rods in sequence, and the lower lacing line closely sticks to the bottoms of peripheral grooves; waste meshes are filled in the peripheral grooves and then sand is fully filled and tamped; the twelve-strand dacron rope is tied on the top end of each canvas-sheathed bamboo rod, and the other end of the twelve-strand dacron rope is tied with a wooden pole which is fixedly arranged in sandy soil on the bottom of the jellyfish pool.

Description

technical field [0001] The invention relates to the technology for making jellyfish bar facilities. Background technique [0002] Jellyfish is one of the popular seafood, rich in nutrition. The complete set of equipment and breeding technology for the jellyfish pen comprehensively applies multi-disciplinary technologies such as marine engineering, feed nutrition and disease control. The existing jellyfish fence devices generally use single-thread, single-knot polyethylene monofilament mesh and ordinary synthetic fiber ropes. After about two years of use, they are discarded as waste rope nets. The raw materials of rope nets consume a lot and affect the ecological environment. In winter, the jellyfish pen must be put away from the jellyfish pond, otherwise, once the jellyfish pond freezes in winter, the single-thread and single-knot polyethylene monofilament mesh will be torn and damaged, causing economic losses to the jellyfish pond culture. The single-thread single-knot po...

Problems solved by technology

When the single-thread and single-knot polyethylene monofilament mesh is seriously attached to marine biofouling, the overturning event of the pen device will occur. After the pen device capsizes, the jellyfish in the pen device will escape to the outside of the breeding pen device, and the jellyfish fleeing outside the breeding pen device will Some losses were caused to jellyfish farming due to beach-going deaths or casualties from foreign enemies such as fish, shrimp, and crabs.

The single-thread single-knot polyethylene monofilament mesh used for jellyfish breeding is severely fouled and attached to biofouling, resulting in more frequent mesh changes by farmers, high cost of mesh replacement, high labor intensity for mesh replacement, and poor water exchange inside and outside the mesh device. smooth, affect the normal development of cultured jellyfish, affect the labor cost and comprehensive benefits of cultured jellyfish

During the development of jellyfish pens, the problems that have been exposed so far are the raw material consumption of the mesh, the antifouling of the mesh, the overwintering and ice resistance of the fence device, the poor exchange of internal and external water bodies of the fence device, and the use of rods for the fence device. The potential threat of the above-mentioned problems is very great, which has seriously affected the economic benefits of jellyfish farming, and is a technical problem that has not been solved for a long time in this technical field.
