Research on the three-body kelp harvesting ship based on floating raft aquaculture mode
Floating raft is the most widely promoted kelp aquaculture mode in China. Under this mode, kelp production is high, but the ropes are complex and intertwined. The main method of kelp harvesting is manual. To reduce the labor intensity and improve the harvesting efficiency of kelp, this study designs a three-body kelp harvesting ship based on the floating raft aquaculture mode. This ship can lift, transport, collect, and transfer kelp in a single operation. Apart from the manual assistance required for the release and hanging the seedling rope, all other processes are mechanically automated. The diameter and lead of the rotary-screw propulsor blade were determined through Fluent simulation tests. To verify the actual harvesting effect of the three-body kelp harvesting ship, kelp harvesting performance tests were conducted. The results showed that the working speed and efficiency of mechanized harvesting were significantly higher than manual. The mechanical harvesting efficiency was 18.75 times that of manual, and the per capita harvesting efficiency was 9.33 times that of manual. The kelp loss rate of the harvesting ship was 3.25 %, slightly higher than that of manual. This study can provide a certain reference for the mechanized harvesting of kelp in large-scale aquaculture.
期刊介绍:
Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations.
Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas:
– Engineering and design of aquaculture facilities
– Engineering-based research studies
– Construction experience and techniques
– In-service experience, commissioning, operation
– Materials selection and their uses
– Quantification of biological data and constraints
