The invention discloses a device for adjusting buoyancy of underwater equipment. The left side and the right side of a barrel are rigidly connected with a left end cover and a right end cover correspondingly, and sealing is conducted through a sealing ring to form a pressure-resistant cabin; a first-stage piston cylinder, a second-stage piston cylinder, a third-stage piston cylinder and a fourth-stage piston cylinder are arranged in the pressure-resistant cabin, the first-stage piston cylinder is rigidly connected with the left end cover and is sealed through a sealing ring, and the fourth-stage piston cylinder is rigidly connected with the barrel piston and is sealed through a sealing ring; the first-stage piston cylinder, the second-stage piston cylinder, the third-stage piston cylinder and the fourth-stage piston cylinder can axially and relatively slide, a ball screw sliding element is rigidly connected with a barrel piston, a ball screw is axially positioned through a thrust bearing, and the end of the ball screw is rigidly connected with an output shaft of a motor and is sealed through a sealing end cover. The motor rotates to drive the ball screw to rotate, and the ball screw sliding element drives the barrel piston to move axially. The fault occurrence probability is reduced, and the reliability of the system is improved.

    本发明公开了一种水下设备调整浮力用装置,筒体的左右两侧分别与左端盖及右端盖刚性连接,并通过密封圈进行密封形成耐压舱;耐压舱内设置有一级活塞缸、二级活塞缸、三级活塞缸和四级活塞缸,一级活塞缸与左端盖刚性连接,并通过密封圈进行密封,四级活塞缸与筒体活塞刚性连接,并通过密封圈进行密封,一级活塞缸、二级活塞缸、三级活塞缸和四级活塞缸能够进行轴向相对滑动,滚珠丝杠滑动元件与筒体活塞刚性连接,滚珠丝杠通过推力轴承进行轴向定位,滚珠丝杠端部与电机输出轴刚性连接,并通过密封端盖进行密封,电机转动能够带动滚珠丝杠转动,滚珠丝杠滑动元件带动筒体活塞进行轴向移动。本发明降低故障发生的概率,提高系统的可靠性。
