The invention is applicable to the technical field of bionic underwater robots, and provides a fishing robotic fish with adjustable fluctuation fin parameters, which comprises a carrier, a fishing mechanism mounted at the bottom of the carrier, and a fluctuation mechanism comprising a first driving shaft and a second driving shaft, the end of the first driving shaft and the end of the second driving shaft are both connected with driving motors, a plurality of eccentric wheels are installed on the first driving shaft and the second driving shaft at equal intervals, every two adjacent eccentric wheels between the two rotating shafts form an eccentric wheel set, each eccentric wheel set is installed on a swing block, swing rods are installed on the swing blocks, and the swing rods are connected with the driving motors. The oscillating rods in the same group of fluctuation mechanisms are connected with each other through a flexible fin; and a snorkeling mechanism. According to the device, a double-eccentric-wheel structure is innovatively adopted, the adjusting process response is fast, more flexible movement performance is achieved, manual operation can be effectively replaced, the working efficiency is high, and good safety and economic applicability are achieved.

    本发明适用于仿生水下机器人技术领域,提供了一种波动鳍参数可调的捕捞机器鱼,包括载体,所述载体的底部安装有捕捞机构,还包括:波动机构,所述波动机构包括第一驱动轴和第二驱动轴,且所述第一驱动轴和第二驱动轴的端部均连接有驱动电机,所述第一驱动轴和第二驱动轴上均等距安装有若干偏心轮,两个转轴之间相邻的两个偏心轮为一个偏心轮组,各偏心轮组分别安装于一个摆动块上,所述摆动块上安装有摆动杆,同一组所述波动机构中的摆动杆通过一个柔性鳍相互连接;以及潜浮机构。该装置创新性的采用双偏心轮结构,其调节过程响应快,具备更灵活的运动性能,能够有效的代替人工作业,不仅工作效率高,还具有较好的安全性和经济适用性。
