Helm-shaped partition plate for net cage

Abstract

The invention relates to an up-and-down partition plate for a sea floating raft cultivation net cage, which is formed by modifying the conventional up-and-down partition plate for the net cage into a helm shape so as to meet the matching requirement of new technology, namely an underwater automatic washing device (a ring-shaped net scraper) for the net cage. The technical scheme is that: the up-and-down partition plate for the net cage is formed into the helm shape by injection molding or compression molding by using plastic with certain elasticity at one time, and the up-and-down partition plate for the net cage is assembled with a net and other intermediate partition plates for the net cage by the traditional method so as to form the net cage with the helm-shaped up-and-down partition plate. The diameter of the ring part of the helm is equal to that of the intermediate partition plate of the net cage, a steering handle is flaky bar-shaped, and the radius of the ring part from the top end to the center of the helm is over 80mm greater than that of the inner ring of the ring-shaped net scraper. The helm-shaped partition plate for the net cage can prevent the ring-shaped net scraper which is sleeved on the net cage from breaking away from the net cage from neither upside nor downside in sea water, but the steering handle can be folded by manpower, so that the ring-shaped net scraper can be conveniently sleeved on the net cage by using the partition plate. The helm-shaped partition plate for the net cage has the advantages of labor saving, economy, simple structure and easy operation.

Description

Technical field [0001] The present invention relates to a kind of upper and lower partitions on the net cage of floating raft culture in the sea, which is to transform the upper and lower partitions of the existing circular net cage into a steering wheel shape, so as to satisfy a new technology - net cage underwater automatic cleaning device ( Ring net scraping) supporting needs. Background technique [0002] my country has a vast sea area, and the marine aquaculture industry is developing rapidly. The aquaculture output ranks first in the world, and shellfish aquaculture accounts for more than 70% of the total output. At present, floating raft cage aquaculture is widely used. The research on the prevention and control of fouling on net cages of marine shellfish has been carried out for many years, and many papers at home and abroad have reported that fouling attached to net cages is one of the main causes of poor growth and death of shellfish. How to effectively prevent an...
