Scallop breeding cage with automatic underwater surface cleaner

Abstract

The invention relates to a scallop breeding cage with an automatic underwater surface cleaner, which is composed of a PVC (polyvinyl chloride) rotary disk, a stainless steel clamp, two or more circular hoops and a plurality of polyethylene ropes. The surface of the PVC rotary disk is provided with hollow round holes, and the ropes for suspending the breeding cage pass through the round hole at the center of the PVC rotary disk. The stainless steel clamp is fixed to the bottom of the PVC rotary disk. The circular hoops are respectively made of PVC and stainless steel, the circular hoops are slightly larger than a partition disk inside the breeding cage in diameter, the circular hoops are arranged in parallel from top to bottom, the circular hoops are connected together through the polyethylene ropes, and the polyethylene ropes are evenly wound on the periphery of each circular hoop and sequentially tied to the circular hoops. An assembled device is sleeved on the breeding cage and driven by ocean currents and waves to automatically circle round the cage, and the polyethylene ropes continuously rub the outside surface of the breeding cage to effectively reduce fouling organisms in attachment.

Description

technical field [0001] The invention relates to a net cage for scallop culture, in particular to an underwater automatic cleaning device for the outer surface of a scallop culture cage. Background technique [0002] Shallow sea raft-type hanging cage culture is a widely used shellfish intensive culture method. In recent years, with the increase of breeding species and farming equipment, raft farming equipment such as floats, floating stems, hanging ropes, and net cages provide good attachment substrates and living conditions for the spread of fouling organisms. These fouling organisms such as sea squirts 1. The attachment of mussels has a great influence on the growth of cultured shellfish and the life of cultured cages. First of all, the shellfish cultured in the net cage mainly rely on the intake of food brought by water exchange, and the fouling organisms on the breeding net cage will block the breeding cage, resulting in a decrease in the amount of water exchange inside...

AI Technical Summary

Problems solved by technology

However, since most fouling organisms have a free-living larval stage, they can spread rapidly and attach in large quantities in a short period of time, which brings great difficulties to antifouling and decontamination.

How to effectively prevent and remove fouling organisms has always been a worldwide problem, especially from the perspective of breeding, it is even more difficult to control fouling organisms on breeding equipment. At present, there is no cost-effective method to reduce the adhesion of fouling organisms on cages
