The invention provides a three-dimensional space maneuvering bionic robot fish and a buoyancy adjusting device. The three-dimensional space maneuvering bionic robot fish comprises a main body structure, a propeller, a buoyancy adjusting device and pectoral fins. The buoyancy adjusting device comprises a buoyancy cylinder and a volume adjusting mechanism arranged in the buoyancy cylinder, the two ends of the buoyancy cylinder are sealed through watertight hatch covers. Water inlet and outlet holes are formed in two ends of the buoyancy cylinder; the volume adjusting mechanism comprises steppingmotors, lead screws, a movable support and a piston; the piston is fixed to one end of the movable support; a disc with a threaded hole in the middle is fixed to the other end of the movable support;the tails of the two stepping motors are fixedly connected; an output shaft of each stepping motor is connected with one lead screw; and the lead screws are matched with the threaded holes of the disc. The device can ensure that the robotic fish rapidly floats up and dives down, and effectively solves the problem that the three-dimensional space maneuverability of the current robotic fish is weak.

    本发明提供的是一种三维空间机动仿生机器鱼及浮力调节装置。三维空间机动仿生机器鱼包括主体结构、推进器、浮力调节装置和胸鳍。浮力调节装置,包括浮力筒和设置于浮力筒内的体积调节机构,浮力筒的两端通过水密舱盖密闭,浮力筒的两端均开有进出水孔,所述的体积调节机构包括步进电机、丝杠、可移动支架和活塞,可移动支架的一端固定活塞,可移动支架的另一端固定中间有螺纹孔的圆盘,两台步进电机的尾部固连,每台步进电机的输出轴上连接一根丝杠,所述丝杠与圆盘的螺纹孔配合。本发明可保证机器鱼快速上浮下潜,有效解决了当前机器鱼三维空间机动能力较弱的问题。
