The invention discloses a floating and sinking mechanism of a bionic robotic fish. The floating and sinking mechanism comprises a body, a head is arranged on the right side of the body, a mounting frame is movably connected to the left side of the head, a bent rod is fixed to the right end of the mounting frame, a plurality of frameworks are fixed to the bent rod, the outer sides of the frameworksare wrapped with outer membranes, and fish tails are arranged at the right ends of the frameworks; a water tank is rotatably connected to the inner side of the mounting frame, an elastic rope and a PLC control part are arranged at the upper end of the water tank, ventral fins are arranged on the front side and the rear side of the water tank, a stop lever is vertically fixed to the upper portionof the left side of the water tank, a base is mounted at the lower end of the water tank, and a water pump is rotatably mounted in the base. By controlling rotation of the water pump, water injectionor drainage into the water tank is controlled, the gravity and buoyancy of the water tank are changed, and the controller can float up and sink down efficiently.

    本发明公开了一种仿生机器鱼的上浮下沉机构,包括本体,所述本体的右侧设置有有头部,头部的左侧活动连接有安装架,安装架的右端固定有弯折杆,弯折杆的固定有若干个骨架,骨架的外侧包覆有外膜,骨架的右端设置有鱼尾;所述安装架的内侧转动连接有水箱,水箱的上端分别设置有弹性绳和PCL控制件,水箱的前后两侧均设置有腹鳍,水箱的左侧上部竖向固定有挡杆,水箱的下端安装有底座,底座内转动安装有水泵。本发明通过控制水泵的转动,从而控制对水箱内注水或者排水,改变其重力和浮力,可以高效的控制器上浮下沉。
