A buoyancy adjusting device for a balance micro-force type underwater robot belongs to the field of electronics and structures, and is structurally characterized in that a closed space is defined by a substrate, a displacement plate and a flexible telescopic pipe, and a displacement driver and a spring are used as active power to carry out volume change; according to the specific installation relation, the displacement driver fixed to the base plate rotates and drives the threaded body fixed to the displacement plate or the open end of the piezoelectric ceramic stacked rod through threads of a motor rotor to directly drive the displacement plate to move up and down so as to change the size of the space between the base plate and the displacement plate; the spring is placed between the base plate and the displacement plate and forms certain thrust to push the displacement plate so as to support and balance external water pressure; the displacement driver is connected with an external controller through a sealed lead; the flexible telescopic pipe is a tubular object which can resist radial pressure and can stretch out and draw back in the axial direction, and the flexible telescopic pipe can be formed by connecting a displacement cylindrical surface and a hose or formed by directly connecting a gas-pipe-shaped telescopic pipe with the base plate and the displacement plate. The interior of the adjusting device is vacuumized through a sealed air exhaust hole or a non-sealed air exhaust hole when the combined body is assembled; when current is excited through the lead, the displacement driver forces the displacement plate to move up and down to change the volume, and the purpose of adjusting the buoyancy of the buoyancy adjusting device is achieved.
平衡微力式水下机器人浮力调节装置,属于电子及结构领域.其构造是由基板、位移板、柔性伸缩管围成闭合空间、由位移驱动器、弹簧作为有源动力来进行变容;具体安装关系包括:固定在基板上的位移驱动器,通过电机转子的螺纹来旋转驱动与位移板固定的螺纹体或压电陶瓷叠棒的开放端来直接驱动位移板上下位移来改变基板与位移板之间的空间大小;弹簧放置在基板与位移板之间,并形成一定的推力来推动位移板,以支撑平衡外界的水压;位移驱动器通过密封的引线与外部控制器连接;柔性伸缩管是一个能抵抗径向压力而又能轴向伸缩的管状物、可以由位移柱面与软管连接而成或由气管状伸缩管直接连接基板、位移板组合而成;本调节装置的内部是通过密封抽气孔或无密封抽气孔而在组装合体时抽取真空;当电流通过引线激励时,位移驱动器将迫使位移板上下位移来改变体积,达到了调整该浮力调节装置浮力的目的。
