基于仿生学的梭子蟹蟹钳收拢装置设计

Design of a bionics-based Portunus crab claw closing device

  • 摘要: 为解决梭子蟹捕捞后的抱团问题,需将蟹钳进行单个捆绑,而蟹钳收拢是实现蟹钳捆绑的关键环节。研究设计了一种基于仿生学的梭子蟹蟹钳收拢装置。该装置的设计灵感汲取自梭子蟹蟹钳的自然运动方式,通过对蟹钳的生理结构进行细致分析,深入理解其活动特点,据此设计出一种蟹钳仿生收拢装置。实验结果表明,该装置对10只不同体质量的梭子蟹进行收拢测试,成功收拢了8只,对体积133 mm3、130 g以上的梭子蟹,收拢效果较好。该装置为有效解决梭子蟹蟹钳捆绑问题,提供了一个初步而有效的解决方案。

     

    Abstract: In order to solve the problem of holding pike crabs after fishing, the crab claw of pike crabs need to be tied up individually, and crab claw closing is important for crab claw binding. In this study, a bionics-based crab claw closing device for pike crabs was designed. The design of this device is inspired by the natural movement of Portunus crab claws. After a careful analysis of the physiological structure of crab claw, we understood the characteristics of their activities well, and then designed this bionics-based crab claw closing device. The device tested the pincer closing for 10 Portunus crabs of different body masses, and 8 individuals were successfully closed. For the crabs with size of 133 mm3 and mass over 130 g, the effect is better. Thus, the device provides a preliminary and effective solution to effectively solve the problem of Portunus crab claw closing.
