Abstract
The invention provides a net-coat connection and fixing structure for shallow sea fence pasture; a plurality of rectangular net-coats are connected end to end and from left to right together and enclose a sea area culture area, and the joints of two adjacent net-coats are fixed at column piles erected at the periphery of the marine culture area by dampers; each net-coat is a copper net, and reinforcing structures are arranged on four sides of the copper nets and in a rectangular area. The reinforcing structures are bundled and fixed on the copper nets; a floating body is fixed on the top edgeof each net-coat. The net-coat connection and fixing structure provided by the invention is characterized in that a plurality of meshes are connected to enclose an area, and two mesh nodes are connected with the column piles by the dampers. The dampers play roles in buffering and resisting wind waves. At the same time, the copper nets are used as the net-coats, the advantages of copper alloy netsin bacteriostasis and biological adhesion prevention are utilized, the abrasion of cultured fish bodies caused by regular replacement and cleaning of traditional net cage net-coats is avoided, the occurrence of fish diseases is reduced, smooth internal and external exchange of culture water bodies is maintained, and the ecological and healthy culture is realized.
Description
technical field [0001] The invention relates to the field of marine aquaculture, in particular to a netting connection and fixing structure for shallow sea fence pastures. Background technique [0002] Cage aquaculture is a relatively mature aquaculture model, and its defects are also obvious. The aquaculture is too concentrated and the aquaculture density is too high, the activity space of fish is relatively small, and the cost per unit of aquaculture water is high. In particular, the volume of the flexible net cage shrinks obviously under the action of ocean currents and wind waves. In recent years, a kind of fence-based farming has been developed in the nearby coastal areas, and the results have been good. At the same time, in recent years, it has been repeatedly invaded by typhoons, resulting in damage to the nets, and the escape of the cultured fish has suffered heavy losses. [0003] The purpose of the present invention is how to improve the stress strength of the net...
