Abstract:

In the existing schemes of kelp harvesting ships,the harvesting device is solidified on the ship,which makes the ship can only be used for kelp harvesting.In addition,there are also problems such as high picking loss,difficult to adapt to the change of tide and inability to cut the tips of kelp according to the required length.All of these have made it difficult to popularize the mechanical harvesting of kelp in China.In view of this,the harvesting device was designed in a modular bionic way:a container was used as the carrier,and a retractable pitching guiding mechanism was set inside it,which could adjust the harvesting angle and the distance from the kelp to the ship with the change of the current;the guiding mechanism cooperated with the limiting-dragging unit to guide and drag the kelp into the harvesting module;with the cooperation of cutting unit and guiding mechanism,the kelp entering the harvesting module could be rooted and taped as required.This scheme realized the separation of ship and machine,which not only improved the utilization rate of the recovery device,but also improved the utilization rate of the ship,and also reduced the labor intensity and improved the labor efficiency.This program was likely to promote the generation of marine harvesting teams,and made the harvesting teams,marine ranches,and local ship owners jointly benefit,promoted the generation of a new model of marine ranch management,and helped kelp become an important producer of blue carbon.However,in this scheme,there were still problems such as mechanism corrosion prevention and intelligent operation that needed further study.
