The invention provides an underwater robot arm with variable buoyancy. The underwater robot arm comprises a box body, a pressure cylinder, a first electric telescopic rod, and a piston. The two sidesof the pressure cylinder are installed in the box body through fixing rods. The bottom of the first electric telescopic rod is fixed to the bottom of the inner wall of the pressure cylinder. The bottom of the piston is fixed to the top of the first electric telescopic rod. According to the underwater robot arm provided by the invention, float bowls are symmetrically distributed on the two sides ofa box body; the area of the air cavity in each flow bowl is adjusted, so that the buoyancy of the box body on the two sides and the whole buoyancy of the float bowl are conveniently adjusted and controlled; the mechanical arm assembly on the box body can be conveniently moved up and down, so that the depth of the underwater robot arm is conveniently adjusted; the structure is simple, use is convenient, adjustment and operation can be conducted at different underwater depths, so that different use requirements of users are met.
本发明提供一种浮力可变的水下机器人手臂。所述浮力可变的水下机器人手臂包括:箱体;压力筒,所述压力筒的两侧均通过固定杆安装于所述箱体的内部;第一电动伸缩杆,所述第一电动伸缩杆的底部固定于所述压力筒内壁的底部;活塞,所述活塞的底部固定于所述第一电动伸缩杆的顶部。本发明提供的浮力可变的水下机器人手臂具有箱体的两侧设置有对称分布的浮筒,通过对浮筒内部的空气腔的面积进行调节,以便于对两侧的箱体以及浮筒整体的浮力进行调节和控制,方便对箱体上的机械臂组件的上下移动,以便于调节水下机器人手臂的深度,结构简单,使用方便,能够在水下的不同深度进行调节和作业,满足使用者不同的使用需求。
